6 EMCORE CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS NOTE 1. Interim Financial Information and Description of Business The accompanying unaudited condensed consolidated financial statements of EMCORE Corporation ("EMCORE" or the "Company") reflect all adjustments considered necessary by management to present fairly the Company's consolidated financial position as of March 31, 2001, the consolidated results of operations for the three and six-month periods ended March 31, 2001 and 2000 and the consolidated cash flows for the six-month periods ended March 31, 2001 and 2000. All adjustments reflected in the accompanying unaudited condensed consolidated financial statements are of a normal recurring nature unless otherwise noted. Prior period balances have been reclassified to conform with the current period financial statement presentation. The results of operations for the three and six-month periods ended March 31, 2001 are not necessarily indicative of the results for the fiscal year ending September 30, 2001 or any future interim period. EMCORE has two reportable operating segments: the systems-related business unit and the materials-related business unit. The systems-related business unit designs, develops and manufactures tools and manufacturing processes used to fabricate compound semiconductor wafer and devices. This business unit assists our customers with device design, process development and optimal configuration of TurboDisc production systems. Revenues for the systems-related business unit consist of sales of EMCORE's TurboDisc(R) production systems as well as spare parts and services related to these systems. The materials-related business unit designs, develops and manufactures compound semiconductor materials. Revenues for the materials-related business unit include sales of semiconductor wafers, devices and process development technology. EMCORE's vertically-integrated product offering allows it to provide a complete compound semiconductor solution to its customers. The segments reported are the segments of the Company for which separate financial information is available and for which gross profit amounts are evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. The Company does not allocate assets or operating expenses to the individual operating segments. Services are performed for each other however there are no intercompany sales transactions between the two operating segments. Available segment information has been presented in the Statements of Operations. NOTE 2. Joint Ventures In May 1999, General Electric Lighting and the Company formed GELcore, a joint venture to develop and market High Brightness Light-Emitting Diode ("HB LED") lighting products. General Electric Lighting and the Company have agreed that this joint venture will be the exclusive vehicle for each party's participation in solid state lighting. Under the terms of the joint venture agreement, the Company has a 49% non-controlling interest in the GELcore venture and accounts for its investment under the equity method of accounting. For the three and six-month periods ended March 31, 2001, the Company recognized a loss of $0.9 million and $2.2 million, respectively, related to this joint venture which has been recorded as a component of other income and expense. As of March 31, 2001, the Company's net investment in this joint venture amounted to $7.2 million. In March 1997, the Company and a subsidiary of Uniroyal Technology Corporation formed Uniroyal Optoelectronics LLC, a joint venture, to manufacture, sell and distribute HB LED wafers and package-ready devices. Under the terms of the joint venture agreement, the Company has a 49% non-controlling interest in this joint venture and accounts for its investment under the equity method of accounting. In January 2001, the Company invested an additional $0.8 million in this venture. For the three and six-month periods ended March 31, 2001, the Company recognized a loss of $2.8 million and $5.6 million, respectively related to this joint venture, which has been recorded as a component of other income and expense. As of March 31, 2001, the Company's net investment in this joint venture amounted to $4.2 million. NOTE 3. Acquisitions In January 2001, the Company purchased Analytical Solutions, Inc., and Training Solutions, Inc. both located in Albuquerque, New Mexico. These companies provide engineering support and analytical services in the form of performance analysis, failure analysis, cross sectioning and parts qualification to a wide array of high technology companies. The Company intends that the acquisition of these companies will accelerate product development and qualification with customers, particularly in fiberoptics. The total consideration for these 6

7 two companies was approximately $4.0 million which was paid in both cash and the Company's common stock. The acquisition was recorded using the purchase method of accounting. The Company allocated approximately $3.1 million to goodwill which is being amortized over a period of five years. NOTE 4. Earnings Per Share The Company accounts for earnings per share under the provision of Statement of Financial Accounting Standards No. 128 "Earnings per share". Basic earnings per common share were calculated by dividing net income (loss) by the weighted average number of common stock shares outstanding during the period. Diluted earnings per common share were calculated by dividing net income by the weighted average number of shares and dilutive potential shares outstanding during the year, assuming conversion of the potential shares at the beginning of the period presented. Shares issuable upon conversion of stock options and other performance awards have been included in the diluted calculation of weighted-average shares to the extent that the assumed issuance of such shares would have been dilutive, as illustrated below. The following table reconciles the number of shares utilized in the earnings per share calculations for the three and six-month periods ending March 31, 2001 and 2000, respectively. Three Months Six Months Ended March 31, Ended March 31, ----------------- -------------------- 2001 2000 2001 2000 Net income (loss)................................. $2,944 ($4,207) ($4,064) ($10,865) Preferred stock dividends.................... -- (15) -- (82) Periodic accretion of redeemable preferred stock to mandatory redemption value............................. -- (5) -- (40) ------ ------ ------ ------- Net income (loss) attributable to common shareholders.......................... $2,944 ($4,227) ($4,064) ($10,987) ====== ====== ====== ======= Net income (loss) per basic share............ $0.09 ($0.14) ($0.12) ($0.39) ====== ====== ====== ======= Net income (loss) per diluted share.......... $0.08 ($0.14) ($0.12) ($0.39) ====== ====== ====== ======= Weighted average of outstanding common shares - basic............................... 34,319 29,790 34,158 28,628 Effect of dilutive securities: Stock option and warrants.................. 4,067 -- -- -- ------ ------ ------ ------- Weighted average of outstanding common shares - diluted............................. 38,386 29,790 34,158 28,628 ====== ====== ====== ======= NOTE 5.

Inventories The components of inventories consisted of the following: As of As of (Amounts in thousands) March 31, 2001 September 30, 2000 -------------- ------------------ Raw materials................... $30,181 $19,594 Work-in-process............... 11,244 8,831 Finished goods................ 2,386 2,299 --------------- ------------ Total $43,811 $30,724 =============== ============ NOTE 8. Related Parties The President of Hakuto Co. Ltd. ("Hakuto"), the Company's Asian distributor, is a member of the Company's Board of Directors and Hakuto is a minority shareholder of the Company. During the three and six-month periods ended March 31, 2001, sales made through Hakuto amounted to approximately $4.9 million and $7.8 million, respectively. During the three and six-month periods ended March 31, 2000, sales made through Hakuto amounted to approximately $3.8 million and $7.4 million respectively. From time to time, the Company has lent money to certain of its executive officers and directors. Pursuant to due authorization from the Company's Board of Directors, the Company lent $3.0 million to Reuben F. Richards, Jr., Chief Executive Officer and a director of the Company. The promissory note bears interest at a rate of 5.18% per annum, compounded annually. The note is fully secured by a pledge of certain shares of the Company's common stock. Principal and accrued interest is payable in February 2004. 8

9 NOTE 9. Debt Facilities On March 1, 2001, the Company entered into an Amended and Restated Revolving Loan and Security Agreement with First Union National Bank. This credit facility provides for revolving loans in an amount up to $20.0 million outstanding at any one time, depending on the Company's borrowing base. These loans bear interest payable monthly in arrears at a rate equal to the lesser of the prime rate and LIBOR plus a margin of 1.50%. The credit facility matures on January 31, 2003. The loans under the credit facility are secured by a security interest in substantially all of our personal property. NOTE 10. Recent Accounting Pronouncements In December 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 101. ("SAB 101") "Revenue Recognition in Financial Statements," which provides guidance on the recognition, presentation, and disclosure of revenue in financial statements filed with the SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue and provides guidance for disclosures related to revenue recognition policies. The Company will adopt SAB 101 by the fourth quarter of fiscal year 2001. Currently, the Company recognizes revenue from system sales upon shipment, when title passes to the customer. Subsequent to product shipment, the Company incurs certain installation costs at the customer's facility that are estimated and accrued at the time the sale is recognized. SAB 101 will require the Company to defer revenue and costs related to this installation portion until the service is completed. Had the Company adopted SAB 101, management has determined the impact of such adoption would have resulted in a deferral of approximately $4.0 million of system revenue and an decrease in net income of approximately $3.3 million during the three months ended March 31, 2001. Generally, system installation takes 2-4 weeks, therefore, revenue deferral would be predominantly recognized in the ensuing quarter and the adoption of SAB 101 would be considered only a timing difference predominately on systems shipped during the last month of a quarter. Management does not anticipate that SAB 101 will have an effect on the Company's material and device revenues. NOTE 11. Subsequent Events Debt Facilities - On May 2, 2001 the Company announced it had agreed to privately place $150 million aggregate principal amount of 5% convertible subordinated notes due 2006. The notes are convertible into EMCORE common stock at a conversion price of $48.76 per share. The Company also granted the initial purchasers of the notes a 30-day option to purchase an additional $25 million principal amount of the notes. On May 7, 2001, the Company completed the private placement of $175 million aggregate principal amount of the notes. The Company intends to use the proceeds of the offering for general corporate purposes, including capital expenditures, working capital, funding its joint ventures, repaying existing indebtedness, and research and development. In addition, the Company may use a portion of the proceeds of the offering to strategically acquire or invest in complementary businesses, products or technology, either directly or through its joint ventures. Joint Venture - On April 11, 2001, the Company invested an additional $3.9 million into the GELcore joint venture. Commitments and Contingencies - In 1992, EMCORE received a royalty bearing, non-exclusive license under a patent held by Rockwell International Corporation which relates to an aspect of the manufacturing process used by its TurboDisc systems. In October 1996, EMCORE initiated discussions with Rockwell to receive additional licenses to permit EMCORE to use this technology to manufacture and sell compound semiconductor wafers and devices. In November 1996, EMCORE suspended these negotiations because of litigation surrounding the validity of the Rockwell patent. EMCORE also ceased making royalty payments to Rockwell under the license during the pendency of the litigation. In January 1999, the case was settled and a judgment was entered in favor of Rockwell. On April 25, 2001, the Company entered into a settlement agreement with Rockwell Technologies, LLC which released us from any liability relating to our manufacture and past sales of epitaxial wafers, chips and devices under Rockwell's US Patent No. 4,368,098. At March 31, 2001, the Company was fully reserved for this settlement payment. 9

10 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS This report contains forward-looking statements based on our current expectations, estimates, and projections about our industry, management's beliefs, and certain assumptions made by us. Words such as "anticipates", "expects", "intends", "plans", "believes", "seeks", "estimates", "may", "will" and variations of these words or similar expressions are intended to identify forward-looking statements. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. These statements are not a guarantee of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict. Therefore, our actual results could differ materially and adversely from those expressed in any forward-looking statements as a result of various factors, including, but not limited to: rapid growth which places a strain on our resources; our expectation of continued operating losses; rapid technology changes in the compound semiconductor industry that require us to continually improve existing products, design and sell new products and manage the costs of research and development in order to effectively compete; fluctuations in our quarterly operating results which may negatively impact our stock price; the fact that our joint venture partners, who have control of these ventures, may make decisions that we do not agree with and thereby adversely affect our net income; our exposure to export risks since a large percentage of our revenues are from foreign sales; the potential for us to lose sales if we are unable to obtain government authorization to export our products; the fact that our products are difficult to manufacture and small manufacturing defects can adversely affect our production yields and our operating results; lengthy sales and qualifications cycles for our products that are typical of our industry and, in many cases, require us to invest a substantial amount of time and funds before we receive orders; industry demand for skilled employees, particularly scientific and technical personnel with compound semiconductor experience which exceeds the number of skilled personnel available; protecting our trade secrets and obtaining patent protection which is critical to our ability to compete for business; licenses that may be required to continue to manufacture and sell certain of our compound semiconductor wafers and devices, the expense of which may adversely affect our results of operations; interruptions in our business and a significant loss of sales to Asia which may result if our primary Asian distributor fails to effectively market and service our products; our management's stock ownership which gives them the power to control business affairs and prevent a takeover that could be beneficial to unaffiliated shareholders; the consequences of unsuccessful control of the hazardous raw materials used in our manufacturing process which could result in costly remediation fees, penalties or damages under environmental and safety regulations; our business or our stock price which could be adversely affected by issuance of preferred stock; certain provisions of New Jersey Law and our charter which may make a takeover of our company difficult even if such takeover could be beneficial to some of our shareholders; fluctuations in the price of our common stock which may continue in the future. Our Annual Report on Form 10-K and other SEC filings discuss some of the important risk factors that may affect our business, results of operations and financial condition. We undertake no obligation to revise or update publicly and forward-looking statements for any reason. OVERVIEW: EMCORE Corporation designs, develops and manufactures compound semiconductor wafers and devices and is a leading developer and manufacturer of the tools and manufacturing processes used to fabricate compound semiconductor wafers and devices. Compound semiconductors are composed of two or more elements and usually consist of a metal, such as gallium, aluminum or indium, and a non-metal such as arsenic, phosphorus or nitrogen. Many compound semiconductors have unique physical properties that enable electrons to move through them at least four times faster than through silicon-based devices and are therefore well suited to serve the growing need for efficient, high performance electronic systems. EMCORE offers a comprehensive portfolio of products and systems for the rapidly expanding broadband, wireless communications and solid state lighting markets. We have developed extensive materials science expertise and process technology to address our customers' needs. Customers can take advantage of our vertically integrated solutions approach by purchasing custom-designed wafers and devices from us, or by manufacturing their own devices in-house using one of our metal organic chemical vapor deposition ("MOCVD") production systems configured to their specific needs. Our products and systems enable our customers to cost effectively introduce new and improved high performance products to the market faster in high volumes. The growth in our business is driven by the widespread deployment of fiber optic networks, introduction of new wireless networks and services, rapid 10

11 build-out of satellite communication systems, increasing use of more power efficient lighting sources, increasing use of electronics in automobiles and emergence of advanced consumer electronic applications. Also, the growing demands for higher volumes of a broad range of higher performance devices has resulted in manufacturers increasingly outsourcing their needs for compound semiconductor wafers and devices. Our expertise in materials science and process technology provides us with a competitive advantage to manufacture compound semiconductor wafers and devices in high volumes. We have increased revenues at a compound annual growth rate ("CAGR") of 30% over the three fiscal years ended September 30, 2000, from $47.8 million in fiscal 1997 to $104.5 million in fiscal 2000. Wafers and Devices EMCORE offers a broad array of compound semiconductor wafers and devices, including optical components and components for use in high-speed data communications and telecommunications networks, radio frequency materials ("RF materials") used in mobile communications products such as wireless modems and handsets, solar cells that power commercial and military satellites high brightness light-emitting diodes ("HB LEDs") for several lighting markets and magneto resistive sensors ("MR sensors") for various automotive applications. o Optical Components and Modules. Our family of vertical cavity surface emitting lasers ("VCSEL") and VCSEL array transceiver and transponder products, as well as our photodiode array components, serve the rapidly growing high-speed data communications network markets, including the Gigabit Ethernet, FibreChannel, Infiniband, and Very Short Reach OC-192, the emerging Very Short Reach OC-768 and related markets. Our strategy is to manufacture high cost optical components and subassemblies in-house, using our proprietary technologies, to reduce the overall cost of our transceiver and transponder modules. o RF Materials. We currently produce 4-inch and 6-inch InGaP HBT and pHEMT materials that are used by our wireless customers for power amplifiers for GSM, TDMA, CDMA and the emerging 3G multiband wireless handsets. o Solar Cells.

Benefits of Compound Semiconductors Recent advances in information technologies have created a growing need for efficient, high- performance electronic systems that operate at very high frequencies, have increased storage capacity and computational and display capabilities and can be produced cost-effectively in commercial volumes. In the past, electronic systems manufacturers have relied on advances in silicon semiconductor technology to meet many of these demands. However, the newest generation of high-performance electronic and optoelectronic applications require certain functions that are generally not achievable using silicon-based components. Compound semiconductors have emerged as an enabling technology to meet the complex requirements of today's advanced information systems. Many compound semiconductor materials have unique physical properties that allow electrons to move at least four times faster than through silicon-based devices. 11

12 Advantages of compound semiconductor devices over silicon devices include: operation at higher speeds; lower power consumption; less noise and distortion; and optoelectronic properties that enable these devices to emit and detect light. Although compound semiconductors are more expensive to manufacture than the more traditional silicon-based semiconductors, electronics manufacturers are increasingly integrating compound semiconductors into their products in order to achieve the higher performance demands of today's electronic products and systems. Strategy Our objective is to capitalize on our position as a leading developer and manufacturer of compound semiconductor tools and manufacturing processes to become the leading supplier of compound semiconductor wafers and devices. The key elements of our strategy are to: apply our core materials and manufacturing expertise across multiple product applications; target high growth market opportunities; continue to recognize greater value for our core technology; partner with key industry participants; and, continue our investment in research and development to maintain technology leadership.

13 EMCORE has generated a significant portion of its sales to customers outside the United States. EMCORE anticipates that international sales will continue to account for a significant portion of revenues. Historically, EMCORE has received substantially all payments for products and services in U.S. dollars and therefore EMCORE does not currently anticipate that fluctuations in any currency will have a material effect on its financial condition or results of operations. The following chart contains a breakdown of EMCORE's worldwide revenues by geographic region. For the fiscal years ended September 30, - --------------------------------------------------------------------------------------------------------------------- 2000 1999 1998 - --------------------------------------------------------------------------------------------------------------------- (in thousands) Revenue % of revenue Revenue % of revenue Revenue % of revenue ------------- --------------- ----------- --------------- ----------- ---------------- Region: North America $64,174 62% $27,698 48% $26,648 61% Asia 34,656 33% 28,211 48% 15,527 35% Europe 5,676 5% 2,432 4% 1,585 4% --------------------- ------------- --------------- ----------- --------------- ----------- ---------------- TOTAL $104,506 100% $58,341 100% $43,760 100% ======== ==== ======= ==== ======= ==== For the six months ended March 31, ------------------------------------------------------------------------------------------- 2001 2000 -------------------- -------------------------------------- ------------------------------- (in thousands) Revenue % of revenue Revenue % of revenue ------------------ ------------------- --------------- --------------- Region North America $45,744 52% $22,422 55% Asia 35,639 41% 13,303 33% Europe 6,588 7% 4,701 12% -------------------- ------------------ ------------------- --------------- --------------- TOTAL $87,971 100% $40,426 100% ======= ==== ======= ==== As of March 31, 2001, EMCORE had an order backlog of $155.5 million scheduled to be shipped through March 31, 2002. This represents an increase of 24% or $30.5 million since September 30, 2000. March 2001 backlog also compares favorably to the sequential backlog reported at December 31, 2000 of $155.0 million. EMCORE includes in backlog only customer purchase orders that have been accepted by EMCORE and for which shipment dates have been assigned within the 12 months to follow and research contracts that are in process or awarded. Wafer and device agreements extending longer than one year in duration are included in backlog only for the ensuing 12 months. EMCORE receives partial advance payments or irrevocable letters of credit on most production system orders. EMCORE has two reportable operating segments: the systems-related business unit and the materials-related business unit. The systems-related business unit designs, develops and manufactures tools and manufacturing processes used to fabricate compound semiconductor wafer and devices. This business unit assists our customers with device design, process development and optimal configuration of TurboDisc production systems. Revenues for the systems-related business unit consist of sales of EMCORE's TurboDisc production systems as well as spare parts and services related to these systems. The materials-related business unit designs, develops and manufactures compound semiconductor materials. Revenues for the materials-related business unit include sales of semiconductor wafers, devices, packaged devices, modules and process development technology. EMCORE's vertically-integrated product offering allows it to provide a complete compound semiconductor solution to its customers. The segments reported are the segments of EMCORE for which separate financial information is available and for which gross profit amounts are evaluated regularly by executive management in deciding 13

14 how to allocate resources and in assessing performance. EMCORE does not allocate assets or operating expenses to the individual operating segments. Services are performed for each other however there are no intercompany sales transactions between the two operating segments. Comparison of three and six-month periods ended March 31, 2001 and 2000 Revenues. EMCORE's revenues increased 100% or $24.0 million from $23.9 million for the three- month period ended March 31, 2000 to $47.9 million for the three-month period ended March 31, 2001. For the six-month period ended March 31, 2001, revenues increased 118% or $47.5 million from $40.4 million in 2000 to $88.0 million in 2001. On a sequential basis, revenues reached record levels for the fifth consecutive quarter and increased 20% or $7.8 million from $40.1 million reported in the prior quarter. This increase in revenues was attributable to both systems and materials-related product lines. For the six-month period, systems-related revenues increased 134% or $33.9 million from $25.3 million to $59.3 million. On a sequential basis, systems-related revenues increased 21% or $5.7 million from $26.8 million reported in the prior quarter. The number of MOCVD production systems shipped during the six-month period increased 128% from 18 in 2000 to 41 systems in 2001. Management expects fiscal year 2001 system shipments to increase approximate 90% over fiscal year 2000 shipments to approximately 90 MOCVD systems. Materials-related revenues for the six-month period increased 90% or $13.6 million from $15.1 million to $28.7 million. On a sequential basis, materials-related revenues increased 16% or $2.2 million from $13.3 million reported in the prior quarter. This revenue growth was primarily related to sales of solar cells, pHEMT and HBT epitaxial wafers and VCSELs, which increased 39%, 192% and 304%, respectively, from the prior year. As a percentage of revenues, systems and materials-related revenues accounted for 63% and 37%, respectively, for the six-month period ended March 31, 2000 and 67% and 33%, respectively, for the six-month period ended March 31, 2001. EMCORE expects the product mix between systems and materials to approach 50% as other new products are introduced and production of commercial volumes of these materials commences. International sales accounted for 45% of revenues for the six-month period ended March 31, 2000 and 48% of revenues for the six-month period ended March 31, 2001. Gross Profit. EMCORE's gross profit increased 97% or $9.6 million from $9.9 million for the three- month period ended March 31, 2000 to $19.5 million for the three-month period ended March 31, 2001. For the six-month period ended March 31, 2001, gross profit increased 117% or $19.5 million from $16.7 million in 2000 to $36.1 million in 2001. On a sequential basis, gross profit increased 19% or $3.1 million from $16.5 million. For the six-month period, gross profit earned on systems-related revenues increased 160% or $16.5 million from $10.3 million to $26.7 million. This is due primarily to the increase in sales of production systems, as well as, improved manufacturing efficiencies. Component and service related revenues continue to increase since EMCORE's production system installed base now exceeds 400 MOCVD systems. For the six-month period, gross profit earned on materials-related revenues increased 47% or $3.0 million from $6.4 million to $9.4 million. Management expects gross profits on materials-related sales to increase due to recent yield improvements in manufacturing processes and expected increased production output due to EMCORE's strong order backlog of material-related products. Selling, General and Administrative. Selling, general and administrative expenses increased by 43% or $2.3 million from $5.3 million for the three-month period ended March 31, 2000 to $7.6 million for the three-month period ended March 31, 2001. For the six-month period ended March 31, 2001, selling general and administrative expenses increased 45% or $4.5 million from $10.0 in 2000 to $14.5 million in 2001. On a sequential basis, selling, general and administrative expenses increased 8% or $0.6 million from $7.0 million incurred in the prior quarter. A significant portion of the increase was due to headcount increases in marketing and sales personnel to support domestic and foreign markets and other administrative headcount additions to sustain internal support. As a percentage of revenue, selling, general and administrative expenses decreased from 25% for the six-month period ended March 31, 2000 to 17% for the six-month period ended March 31, 2001. On a sequential basis, as a percentage of revenue, selling, general and administrative expenses decreased from 17% realized in the prior quarter to 16%. Goodwill Amortization. Goodwill of $3.1 million was recorded in connection with our acquisitions of Analytical Solutions, Inc. and Training Solutions, Inc. in January 2001. This goodwill is being amortized over a period of five years. During the three months ended March 31, 2001, goodwill amortization totaled $0.1 million. Research and Development. Research and development expenses increased 157% or $7.3 million from $4.7 million in the three-month period ended March 31, 2000 to $12.0 million in the three month-period ended March 31, 2001. For the six-month period ended March 31, 2001, research and development increased 169% or $15.8 million from $9.4 million in 2000 to $25.2 million in 2001. On a sequential basis, research and development expenses decreased 9% or $1.2 million from $13.2 million incurred in the last quarter. The completion and release of 14

15 several new fiber optic products, including a 10 Gbps serial device and 2.5 Gbps LC/SC TOSAs (optical subassemblies) for various data communications network applications, contributed to the decrease. To maintain growth and to continue to pursue market leadership in materials science technology, management expects the amount to continue to invest a significant amount of its resources in research and development. EMCORE expects the amount of research and development expenditures to continue at levels similar to the second quarter's for the remainder of fiscal year 2001 as the Company finalizes the development and commercialization of new fiber optic products, including long wavelength VCSELs (vertical cavity surface emitting lasers), optical subassemblies and modules. As a percentage of revenue, research and development expenses decreased from 33% for the three months ended December 31, 2000 to 25% for the three months ended March 31, 2001. Interest income, net. For the three-month period ended March 31, 2001, net interest income increased $0.2 million from $0.6 million in 2000 to $0.8 million. For the six-month period ended March 31, 2001, interest expense increased 230% or $1.6 million from $0.7 million in 2000 to $2.3 million in 2001. Higher cash balances early in fiscal year 2001 contributed to increased interest income. Other income, net. Other income for the three months ended March 31, 2001 includes a net gain of $5.9 million related to the settlement of litigation. Equity in unconsolidated affiliates. Because EMCORE does not have a controlling economic and voting interest in its joint ventures, EMCORE accounts for these joint ventures under the equity method of accounting. For the three months ended March 31, 2001, EMCORE incurred a net loss of approximately $0.9 million related to the GELcore joint venture, down from a $1.1 million net loss incurred in 2000. On a sequential basis, GELcore's net loss decreased 32% or $0.4 million from $1.3 million incurred last quarter. EMCORE also incurred a net loss of approximately $2.8 million related to the UOE joint venture in the three months ended March 31, 2001, up from a $1.9 million net loss incurred in 2000. On a sequential basis, UOE's net loss remained flat at $2.8 million for each period. Income Taxes. As a result of its losses, EMCORE did not incur any income tax expense in both the three and six-month periods ended March 31, 2001 and 2000. EMCORE has experienced and expects to continue to experience significant fluctuations in quarterly results. Factors which have had an influence on and may continue to influence EMCORE's operating results in a particular quarter include, but are not limited to, the timing of receipt of orders, cancellation, rescheduling or delay in product shipment or supply deliveries, product mix, competitive pricing pressures, EMCORE's ability to design, manufacture and ship products on a cost effective and timely basis, including the ability of EMCORE to achieve and maintain acceptable production yields for wafers and devices, regional economic conditions and the announcement and introduction of new products by EMCORE and by its competitors. The timing of sales of EMCORE's TurboDisc production systems may cause substantial fluctuations in quarterly operating results due to the substantially higher per unit price of these products relative to EMCORE's other products. If the compound semiconductor industry experiences downturns or slowdowns, EMCORE's business, financial condition and results of operations may be materially and adversely affected. Liquidity and Capital Resources EMCORE has funded operations to date through sales of equity, bank borrowings, subordinated debt and revenues from product sales. In June 1999, EMCORE completed a secondary public offering and raised approximately $52.0 million, net of issuance costs. In March 2000, EMCORE completed an additional public offering and raised approximately $127.5 million, net of issuance costs. As of March 31, 2001, EMCORE had working capital of approximately $64.2 million, including $28.8 million in cash, cash equivalents and marketable securities. Cash used for operating activities approximated $17.5 million during the six-month period ended March 31, 2001 as a result of increases in both inventory and accounts receivable. The increase in accounts receivable was within expectations of the 100% increase in revenues from the prior year. For the six months ended March 31, 2001 net cash used for investment activities amounted to $19.3 million, which represents an increase of 38% or $5.3 million from the prior year. For the six months ended March 31, 2001, EMCORE's capital expenditures totaled $55.9 million, which was used primarily for capacity expansion at both New Jersey and New Mexico's manufacturing facilities. EMCORE quadrupled its production capacity for GaInP HBTs and pHEMTs to meet wireless and fiber optic market demands. Completed in January 2001, EMCORE tripled its cleanroom manufacturing capacity in New Mexico by adding on an additional 36,000 square feet to the existing 50,000 square foot building which houses EMCORE's solar cell, optical components and networking products. EMCORE's planned capital expenditures are expected to total approximately $80.0 million during fiscal year 2001. Capital spending in fiscal year 2001 also includes the purchase of and continued upgrades to manufacturing facilities, continued investment in analytical and diagnostic research and development equipment, upgrading and 15

16 purchasing computer equipment and the manufacture of TurboDisc MOCVD production systems used internally for production of materials-related products. EMCORE's net investment in marketable securities was reduced by $38.9 million during the six months ended March 31, 2001. Net cash provided by financing activities for the six months ended March 31, 2001 amounted to approximately $2.8 million primarily from proceeds of stock option exercises and employee participation in EMCORE's Employee Stock Purchase Plan. On May 2, 2001 the Company announced that that it had agreed to privately place $150 million aggregate principal amount of 5% convertible subordinated notes due 2006. The notes are convertible into EMCORE common stock at a conversion price of $48.76 per share. The Company also granted the initial purchasers of the notes a 30-day option to purchase an additional $25 million principal amount of the notes. On May 7, 2001, the Company completed the private placement of $175 million aggregate principal amount of the notes. The Company intends to use the proceeds of the offering for general corporate purposes, including capital expenditures, working capital, funding its joint ventures, repaying existing indebtedness, and research and development. In addition, the Company may use a portion of the proceeds of the offering to strategically acquire or invest in complementary businesses, products or technology, either directly or through its joint ventures. EMCORE believes that its current liquidity, together with available credit, should be sufficient to meet its cash needs for working capital through fiscal year 2002. Item 7A. Quantitative and Qualitative Disclosures About Market Risk During the six months ended March 31, 2001, EMCORE invested in high-grade corporate debt, commercial paper, government securities and other investments at fixed interest rates that vary by security. No other material changes in market risk were identified. EMCORE had no debt outstanding as of March 31, 2001. 16

Any exchange or registration of transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and provided, that this sentence shall not apply to any exchange pursuant to Section 2.07, 2.10, 2.12(a), 3.06, 6.09(a)(7), 4.02 (last paragraph) or 11.05. Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of (a) any Notes for a period of 15 days next preceding any mailing of a notice of Notes to be redeemed, (b) any Notes or portions thereof selected or called for redemption (except, in the case of redemption of a Note in part, the portion not to be redeemed) or (c) any Notes or portions thereof in respect of which a Note has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Note in part, the portion not to be purchased). All Notes issued upon any registration of transfer or exchange of Notes shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. (b) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Notes upon registration of transfer or exchange of Notes. (c) Each Holder of a Note agrees to indemnify the Company, the Registrar and the Trustee against any liability that may result from the registration of transfer, exchange or assignment of such Holder's Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on registration of transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or other beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. SECTION 2.07. REPLACEMENT NOTES. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee's requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 11

17 Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. SECTION 2.08. OUTSTANDING NOTES. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. If the principal amount of any Note is considered paid under Section 6.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date, a Change in Control Payment Date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. SECTION 2.09. TREASURY NOTES. In determining whether the Holders of the required principal amount of Notes have concurred in any notice, direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded. SECTION 2.10. TEMPORARY NOTES. Until certificates representing Notes are ready for delivery, the Company may prepare and execute, and the Trustee, upon receipt of an Authentication Order, shall authenticate and deliver temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate and deliver definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. SECTION 2.11. CANCELLATION. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, redemption, payment or conversion. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, redemption, payment, conversion, replacement or cancellation and shall destroy canceled Notes (subject to the record retention requirement 12

18 of the Exchange Act), in accordance with their normal procedures. All Notes which are redeemed, purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the maturity date shall be delivered to the Trustee for cancellation. Certification of the destruction of all canceled Notes shall be delivered to the Company. The Company may not hold or resell such Notes or issue new Notes to replace Notes that it has purchase or otherwise acquired or that have been delivered to the Trustee for cancellation. SECTION 2.12. ADDITIONAL TRANSFER AND EXCHANGE REQUIREMENTS. (a) TRANSFER AND EXCHANGE OF GLOBAL NOTES. (1) Definitive Notes shall be issued in exchange for interests in the Global Notes only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for the Global Notes or if it at any time ceases to be a "clearing agency" registered under the Exchange Act, if so required by applicable law or regulation and a successor depositary is not appointed by the Company within 90 days, or (y) an Event of Default has occurred and is continuing. In either case, the Company shall execute, and the Trustee shall, upon receipt of an Authentication Order (which the Company agrees to delivery promptly), authenticate and deliver Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Notes in exchange therefor. Only Restricted Definitive Notes shall be issued in exchange for beneficial interests in Restricted Global Notes, and only Unrestricted Definitive Notes shall be issued in exchange for beneficial interests in Unrestricted Global Notes. Definitive Notes issued in exchange for beneficial interests in Global Notes shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Definitive Notes to the persons in whose names such Notes are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. (2) Notwithstanding any other provisions of this Indenture other than the provisions set forth in Section 2.12(a)(1), a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (b) TRANSFER AND EXCHANGE OF DEFINITIVE NOTES. In the event that Definitive Notes are issued in exchange for beneficial interests in Global Notes in accordance with Section 2.12(a)(1) of this Indenture, on or after such event when Definitive Notes are presented by a Holder to a Registrar with a request: (x) to register the transfer of the Definitive Notes to a person who will take delivery thereof in the form of Definitive Notes only; or (y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Definitive Notes presented or surrendered for register of transfer or exchange: 13

19 (1) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.06(a); and (2) in the case of a Restricted Definitive Note, such request shall be accompanied by the following additional information and documents, as applicable: (i) if such Restricted Definitive Note is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such Restricted Definitive Note is being transferred to the Company or a Subsidiary of the Company, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); (ii) if such Restricted Definitive Note is being transferred to a person the Holder reasonably believes is a QIB in accordance with Rule 144A or is being transferred to a Non-U.S. Person in an offshore transaction in accordance with Rule 903 or Rule 904 or pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or (iii) if such Restricted Definitive Note is being transferred (A) pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144 or (B) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144, Rule 903 or Rule 904) and as a result of which, in the case of a Note transferred pursuant to this clause (B), such Note shall cease to be a "restricted security" within the meaning of Rule 144, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or such Registrar so requests, a customary opinion of counsel, certificates and other information reasonably acceptable to the Company and such Registrar to the effect that such transfer is in compliance with the registration requirements of the Securities Act. (c) TRANSFER OF A BENEFICIAL INTEREST IN A RESTRICTED GLOBAL NOTE FOR A BENEFICIAL INTEREST IN AN UNRESTRICTED GLOBAL NOTE. Any person having a beneficial interest in a Restricted Global Note may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Note and the following additional information and documents in such form as is customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Note (all of which may be submitted by facsimile or electronically): (1) if such beneficial interest is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate); or (2) if such beneficial interest is being transferred (i) pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144 or (ii) pursuant to an exemption from the registration requirements of the Securities Act (other 14

20 than pursuant to Rule 144A, Rule 144, Rule 903 or Rule 904) and as a result of which, in the case of a Note transferred pursuant to this clause (ii), such Note shall cease to be a "restricted security" within the meaning of Rule 144, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Trustee so requests, a customary opinion of counsel, certificates and other information reasonably acceptable to the Company and the Trustee to the effect that such transfer is in compliance with the registration requirements of the Securities Act. The Trustee, as a Registrar and Custodian, shall reduce or cause to be reduced the aggregate principal amount of the Restricted Global Note by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Unrestricted Global Note by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted Global Note is then outstanding, the Company shall execute and the Trustee shall, upon receipt of an Authentication Order (which the Company agrees to deliver promptly), authenticate and deliver an Unrestricted Global Note. (d) TRANSFER OF A BENEFICIAL INTEREST IN AN UNRESTRICTED GLOBAL NOTE FOR A BENEFICIAL INTEREST IN A RESTRICTED GLOBAL NOTE. Any person having a beneficial interest in an Unrestricted Global Note may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of a Restricted Global Note (it being understood that only QIBs may own beneficial interests in Restricted Global Notes). Upon receipt by the Trustee of written instructions or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee, on behalf of any person having a beneficial interest in an Unrestricted Global Note and, in such form as is customary for the Depositary, from the Depositary or its nominee on behalf of the person having such beneficial interest in the Unrestricted Global Note (all of which may be submitted by facsimile or electronically) a certification from the transferor (in substantially the form set forth in the Transfer Certificate) to the effect that such beneficial interest is being transferred to a person that the transferor reasonably believes is a QIB in accordance with Rule 144A. The Trustee, as a Registrar and Custodian, shall reduce or cause to be reduced the aggregate principal amount of the Unrestricted Global Note by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Restricted Global Note by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Restricted Global Note is then outstanding, the Company shall execute and the Trustee shall, upon receipt of an Authentication Order (which the Company agrees to deliver promptly), authenticate and deliver a Restricted Global Note. (e) TRANSFERS OF DEFINITIVE NOTES FOR BENEFICIAL INTEREST IN GLOBAL NOTES. In the event that Definitive Notes are issued in exchange for beneficial interests in Global Notes and, thereafter, the events or conditions specified in Section 2.12(a)(1) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Definitive Notes for interests in Global Notes by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if Definitive Notes are presented by a Holder to a Registrar with a request: (x) to register the transfer of such Definitive Notes to a person who will take delivery thereof in the form of a beneficial interest in a Global Note, which request shall specify whether such Global Note will be a Restricted Global Note or an Unrestricted Global Note; or 15

21 (y) to exchange such Definitive Notes for an equal principal amount of beneficial interests in a Global Note, which beneficial interests will be owned by the Holder transferring such Definitive Notes (provided that in the case of such an exchange, Restricted Definitive Notes may be exchanged only for Restricted Global Notes and Unrestricted Definitive Notes may be exchanged only for Unrestricted Global Notes), the Registrar shall register the transfer or make the exchange as requested by canceling such Definitive Note and causing, or directing the Custodian to cause, the aggregate principal amount of the applicable Global Note to be increased accordingly and, if no such Global Note is then outstanding, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate and deliver a new Global Note; provided, however, that the Definitive Notes presented or surrendered for registration of transfer or exchange: (1) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to Section 2.06; (2) in the case of a Restricted Definitive Note to be transferred for a beneficial interest in an Unrestricted Global Note, such request shall be accompanied by the following additional information and documents, as applicable: (i) if such Restricted Definitive Note is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or (ii) if such Restricted Definitive Note is being transferred pursuant to (A) an exemption from the registration requirements of the Securities Act in accordance with Rule 144 or (B) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144, Rule 903 or Rule 904) and as a result of which, in the case of a Note transferred pursuant to this clause (B), such Note shall cease to be a "restricted security" within the meaning of Rule 144, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate), and, if the Company or the Registrar so requests, a customary opinion of counsel, certificates and other information reasonably acceptable to the Company and the Trustee to the effect that such transfer is in compliance with the registration requirements of the Securities Act; (3) in the case of a Restricted Definitive Note to be transferred or exchanged for a beneficial interest in a Restricted Global Note, such request shall be accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Restricted Definitive Note is being transferred to a person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A or is being transferred to a Non-U.S. Person in an offshore transaction in accordance with Rule 903 or Rule 904; (4) in the case of an Unrestricted Definitive Note to be transferred or exchanged for a beneficial interest in an Unrestricted Global Note, such request need not be accompanied by any additional information or documents; and 16

22 (5) in the case of an Unrestricted Definitive Note to be transferred or exchanged for a beneficial interest in a Restricted Global Note, such request shall be accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Unrestricted Definitive Note is being transferred to a person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A or is being transferred to a Non-U.S. Person in an offshore transaction in accordance with Rule 903 or Rule 904. (f) LEGENDS. (1) Except as permitted by the following paragraphs (2) and (3), each Global Note and Definitive Note (and all Notes issued in exchange therefor or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A hereto (each a "Restricted Global Note" for so long as it is required by this Indenture to bear such legend). Each Restricted Global Note shall have attached thereto a certificate (a "Transfer Certificate") in substantially the form called for by footnote 5 to Exhibit A hereto. (2) Upon any sale or transfer of a Restricted Global Note (w) after the expiration of the holding period applicable to sales of the Notes under Rule 144(k) of the Notes Act, (x) pursuant to Rule 144, (y) pursuant to an effective registration statement under the Notes Act or (z) pursuant to any other available exemption (other than Rule 144A) from the registration requirements of the Securities Act and as a result of which, in the case of a Note transferred pursuant to this clause (z), such Note shall cease to be a "restricted security" within the meaning of Rule 144: (i) in the case of any Restricted Definitive Note, any Registrar shall permit the Holder thereof to exchange such Restricted Definitive Note for an Unrestricted Definitive Note, or (under the circumstances described in Section 2.12(e)) to transfer such Restricted Definitive Note to a transferee who shall take such Note in the form of a beneficial interest in an Unrestricted Global Note, and in each case shall rescind any restriction on the transfer of such Note; provided, however, that the Holder of such Restricted Definitive Note shall, in connection with such exchange or transfer, comply with the other applicable provisions of this Section 2.12; and (ii) in the case of any beneficial interest in a Restricted Global Note, the Trustee shall permit the beneficial owner thereof to transfer such beneficial interest to a transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Note and shall rescind any restriction on transfer of such beneficial interest; provided, that such Unrestricted Global Note shall continue to be subject to the provisions of Section 2.12(a)(2); and provided, further, that the owner of such beneficial interest shall, in connection with such transfer, comply with the other applicable provisions of this Section 2.12. (3) Upon the exchange, registration of transfer or replacement of Notes not bearing the legend described in paragraph (1) above, the Company shall execute, and the Trustee shall authenticate and deliver Notes that do not bear such legend and that do not have a Transfer Certificate attached thereto. 17

23 (4) After the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company may with the consent of the Holder of a Restricted Global Note or Restricted Definitive Note, remove any restriction of transfer on such Note, and the Company shall execute, and the Trustee shall authenticate and deliver Notes that do not bear such legend and that do not have a Transfer Certificate attached thereto. (g) TRANSFERS TO THE COMPANY. Nothing in this Indenture or in the Notes shall prohibit the sale or other transfer of any Notes (including beneficial interests in Global Notes) to the Company or any of its Subsidiaries, which Notes shall thereupon be cancelled in accordance with Section 2.11. SECTION 2.13. CUSIP NUMBERS. The Company in issuing the Notes may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption or purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or purchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers. SECTION 2.14. DEFAULTED INTEREST. If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, PROVIDED that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. ARTICLE 3. REDEMPTION AND PREPAYMENT SECTION 3.01. NOTICES TO TRUSTEE. If the Company elects to redeem Notes pursuant to the provisional or optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 20 days but not more than 60 days before a redemption date, an Officers' Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price. SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED. If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in 18

24 compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a PRO RATA basis, by lot or in accordance with any other method the Trustee considers fair and appropriate. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 20 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. SECTION 3.03. NOTICE OF REDEMPTION. At least 20 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. The notice shall identify the Notes to be redeemed and shall state: (a) the redemption date; (b) the redemption price; (c) the then current Conversion Price; (d) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; (e) the name and address of the Paying Agent and Conversion Agent; (f) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (g) that Notes called for redemption must be presented and surrendered to a Paying Agent to collect the Redemption Price; (h) that Holders who wish to convert Notes must surrender such Notes for conversion no later than the close of business on the Business Day immediately preceding the Redemption Date and must satisfy the other requirements in paragraph 8 of the Notes; (i) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; (j) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 19

25 (k) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the Company shall have delivered to the Trustee, at least 40 days prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. SECTION 3.05. DEPOSIT OF REDEMPTION PRICE. One Business Day prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 6.01 hereof. SECTION 3.06. NOTES REDEEMED IN PART. Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company's written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. SECTION 3.07. PROVISIONAL AND OPTIONAL REDEMPTION. (a) The Notes may be redeemed at the election of the Company, as a whole or in part from time to time, at any time prior to May 20, 2004 (a "PROVISIONAL REDEMPTION"), upon at least 20 and not more than 60 days' notice by mail to the Holders of the Notes at a redemption price equal to $1,000 per $1,000 principal amount of the Notes redeemed plus accrued and unpaid interest, if any (such amount, together with the Make-Whole Payment described below, the "PROVISIONAL REDEMPTION PRICE"), to but excluding the date of redemption (the "PROVISIONAL REDEMPTION DATE") if (1) the Closing Sale Price of the Common Stock has exceeded 150% of the Conversion Price for at least 20 Trading Days within a period of any 30 consecutive Trading Days ending on the Trading Day prior to the date of mailing of the notice of Provisional Redemption (the "NOTICE DATE"), and (2) a shelf registration statement covering 20

26 resales of the Notes and the Common Stock issuable upon conversion thereof is effective and available for use and is expected to remain effective and available for use for the 30 days following the Provisional Redemption Date unless registration is no longer required. Upon any such Provisional Redemption, the Company, shall make an additional payment, at its option, in cash or Common Stock or a combination of cash and Common Stock (the "MAKE-WHOLE PAYMENT") with respect to the Notes called for redemption to holders on the Notice Date in an amount equal to $150.00 per $1,000 principal amount of the Notes, less the amount of any interest actually paid (including, if the Provisional Redemption Date occurs after a record date but before an interest payment date, any interest paid or to be paid in connection with such interest payment date) on such Notes prior to the Provisional Redemption Date. Payments made in Common Stock will be valued at 97% of the average closing sales prices of Common Stock for the five Trading Days ending on the day prior to the Redemption Date. The Company shall make the Make-Whole Payment on all Notes called for Provisional Redemption, including those Notes converted into Common Stock between the Notice Date and the Provisional Redemption Date. (b) Except as set forth in clause (a) of this Section 3.07, the Company shall not have the option to redeem the Notes pursuant to this Section 3.07 prior to May 20, 2004. Thereafter, the Company shall have the option to redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption date, if redeemed during the periods set forth below: Period Percentage ------ ---------- Beginning May 20, 2004 through May 14, 2005................ 101.25% Beginning May 15, 2005 and thereafter...................... 100.00% (c) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof. SECTION 3.08. MANDATORY REDEMPTION. The Company shall not be required to make mandatory redemption payments with respect to the Notes. ARTICLE 4. Conversion SECTION 4.01. CONVERSION PRIVILEGE. A Holder of a Note may convert it into fully paid and nonassessable shares of Common Stock at any time prior to maturity at the Conversion Price then in effect, except that, with respect to any Note called for redemption or submitted or presented for purchase pursuant to Section 6.09, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date or Change in Control Payment Date, as the case may be (unless the Company shall default in making the redemption payment or Change in Control Payment when it becomes due, in which case the conversion right shall terminate on the date such default is cured and such Note is redeemed or purchased, as the case may be). The number of shares of Common Stock issuable upon conversion of a 21

27 Note is determined by dividing the principal amount of such Note by the conversion price in effect on the Conversion Date (the "CONVERSION PRICE"). The initial Conversion Price is stated in Section 8 of the Notes and is subject to adjustment as provided in this Article 4. A Holder may convert a portion of a Note equal to any integral multiple of $1,000. Provisions of this Indenture that apply to conversion of all of a Note also apply to conversion of a portion of it. A Note in respect of which a Holder has delivered a Change in Control Payment Notice pursuant to Section 6.09 exercising the option of such Holder to require the Company to purchase such Note may be converted only if such Change in Control Payment Notice is withdrawn by a written notice of withdrawal delivered to a Paying Agent prior to the close of business on the Business Day immediately preceding the Change in Control Payment Date in accordance with Section 6.09. A Holder of Notes is not entitled to any rights of a holder of Common Stock until such Holder has converted its Notes to Common Stock, and only to the extent such Notes are deemed to have been converted into Common Stock pursuant to this Article 4. SECTION 4.02. CONVERSION PROCEDURE. To convert a Note, a Holder must satisfy the requirements in Section 8 of the Notes. The date on which the Holder satisfies all of those requirements is the conversion date (the "CONVERSION DATE"). As soon as practicable after the Conversion Date, the Company shall deliver to the Holder through the Conversion Agent a certificate for the number of whole shares of Common Stock issuable upon the conversion and a check for any fractional share determined pursuant to Section 4.03 hereof. The Person in whose name the certificate is registered shall become the stockholder of record on the Conversion Date and, as of such date, such Person's rights as a Holder shall cease; PROVIDED, HOWEVER, that no surrender of a Note on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person entitled to receive the shares of Common Stock upon such conversion as the stockholder of record of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person entitled to receive such shares of Common Stock as the stockholder of record thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; PROVIDED FURTHER, HOWEVER, that such conversion shall be at the Conversion Price in effect on the date that such Note shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. No payment or other adjustment shall be made for accrued interest or dividends or distributions on any Common Stock issued upon conversion of the Notes. If any Notes are converted during any period after any record date for the payment of an installment of interest but before the next interest payment date, interest for such notes will be paid on the next interest payment date, notwithstanding such conversion, to the Holders of such Notes. Any Notes that are, however, delivered to the Company for conversion after any record date but before the next interest payment date must, except as described in the next sentence, be accompanied by a payment equal to the interest payable on such interest payment date on the principal amount of Notes being converted. The payment to the Company described in the preceding sentence shall not be required if, during that period between a record date and the next interest payment date, a conversion occurs on or after the date that the Company has issued a redemption notice or Change of Control Offer and prior to the date of redemption stated in such notice or the Change on 22

28 Control Payment Date, as the case may be. No fractional shares will be issued upon conversion, but a cash adjustment will be made for any fractional shares. If a Holder converts more than one Note at the same time, the number of whole shares of Common Stock issuable upon the conversion shall be based on the total principal amount of Notes converted. Upon surrender of a Note that is converted in part, the Trustee shall authenticate for the Holder a new Note equal in principal amount to the unconverted portion of the Note surrendered. SECTION 4.03. FRACTIONAL SHARES. The Company will not issue fractional shares of Common Stock upon conversion of a Note. In lieu thereof, the Company will pay an amount in cash based upon the Closing Sale Price of the Common Stock on the last trading day prior to the date of conversion. SECTION 4.04. TAXES ON CONVERSION. The issuance of certificates for shares of Common Stock upon the conversion of any Note shall be made without charge to the converting Holder for such certificates or for any tax in respect of the issuance of such certificates, and such certificates shall be issued in the respective names of, or in such names as may be directed by, the Holder or Holders of the converted Note; PROVIDED, HOWEVER, that in the event that certificates for shares of Common Stock are to be issued in a name other than the name of the Holder of the Note converted, such Note, when surrendered for conversion, shall be accompanied by an instrument of transfer, in form satisfactory to the Company, duly executed by the registered holder thereof or his duly authorized attorney; and PROVIDED FURTHER, HOWEVER, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificates in a name other than that of the Holder of the converted Note, and the Company shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid or is not applicable. SECTION 4.05. COMPANY TO PROVIDE STOCK. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of issuance upon conversion of Notes as herein provided, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Notes for shares of Common Stock. All shares of Common Stock which may be issued upon conversion of the Notes shall be duly authorized, validly issued, fully paid and nonassessable and free of preemptive rights and free of any lien or adverse claim when so issued. The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Notes, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on the Nasdaq National Market or other over-the-counter market or such other market on which the Common Stock is then listed or quoted; PROVIDED, HOWEVER, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Notes into Common Stock in accordance with the provisions of this Indenture, the Company covenants 23

29 to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such automated quotation system or exchange at such time. SECTION 4.06. ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall be subject to adjustment from time to time as follows: (a) STOCK SPLIT AND COMBINATIONS. In case the Company, at any time or from time to time after the issuance date of the Notes (a) subdivides or splits the outstanding shares of its Common Stock, (b) combines or reclassifies the outstanding shares of its Common Stock into a smaller number of shares or (c) issues by reclassification of the shares of its Common Stock any shares of its capital stock, then the Conversion Price in effect immediately prior to that event or the record date for that event, whichever is earlier, will be adjusted so that the holder of any Notes thereafter surrendered for conversion will be entitled to receive the number of shares of the Company's Common Stock or of its other securities which the Holder would have owned or have been entitled to receive after the occurrence of any of the events described above, had those Notes been surrendered for conversion immediately before the occurrence of that event or the record date for that event, whichever is earlier; (b) STOCK DIVIDENDS IN COMMON STOCK. In case the Company, at any time or from time to time after the issuance date of the Notes, pays a dividend or make a distribution in shares of its Common Stock on any class of its capital stock other than dividends or distributions of shares of Common Stock or other securities with respect to which adjustments are provided in paragraph (1) above or with respect to payments of interest or dividend obligations with respect to a particular series of capital stock in accordance with the terms of such capital stock, the Conversion Price will be adjusted so that the Holder of each Note will be entitled to receive, upon conversion of that Note, the number of shares of the Company's Common Stock determined by multiplying (a) the Conversion Price by (b) a fraction, the numerator of which will be the number of shares of Common Stock outstanding and the denominator of which will be the sum of that number of shares and the total number of shares issued in that dividend or distribution; (c) ISSUANCE OF RIGHTS OR WARRANTS. In case the Company issues to all holders of its Common Stock rights or warrants entitling those holders for a period of not more than 60 days to subscribe for or purchase its Common Stock or securities convertible into its Common Stock at a price per share or conversion price per share less than the Current Market Price, the Conversion Price in effect immediately before the close of business on the record date fixed for determination of shareholders entitled to receive those rights or warrants will be reduced by multiplying the Conversion Price by a fraction, the numerator of which is the sum of the number of shares of the Company's Common Stock outstanding at the close of business on that record date and the number of shares of Common Stock that the aggregate offering price of the total number of shares of the Company's Common Stock so offered for subscription or purchase would purchase at the Current Market Price and the denominator of which is the sum of the number of shares of Common Stock outstanding at the close of business on that record date and the number of additional shares of the Company's Common Stock so offered for subscription or purchase. For purposes of this paragraph (3), the issuance of rights or warrants to subscribe for or purchase securities convertible into shares of the Company's Common Stock will be deemed to be the issuance of rights or warrants to purchase shares of the Company's Common Stock into which those securities are convertible at an aggregate offering price equal to the sum of the aggregate offering price of those securities and the minimum aggregate amount, if any, payable upon conversion of those securities into shares of the Company's Common Stock. This adjustment will be made successively whenever any such event occurs; 24

30 (d) DISTRIBUTION OF INDEBTEDNESS, SECURITIES OR ASSETS. In case the Company shall distribute to all or substantially all holders of its Common Stock any shares of capital stock of the Company (other than Common Stock), evidences of indebtedness or other non-cash assets (including securities of any person other than the Company but excluding (1) dividends or distributions paid exclusively in cash or (2) dividends or distributions referred to in subsection (b) of this Section 4.06), or shall distribute to all or substantially all holders of its Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those rights and warrants referred to in subsection (c) of this Section 4.06 and also excluding the distribution of rights to all holders of Common Stock pursuant to the adoption of a stockholders rights plan or the detachment of such rights under the terms of such stockholder rights plan), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the current Conversion Price by a fraction of which the numerator shall be the current market price per share (as defined in subsection (g) of this Section 4.06) of the Common Stock on the record date mentioned below less the fair market value on such record date (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of the portion of the capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date), and of which the denominator shall be the current market price per share (as defined in subsection (g) of this Section 4.06) of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (e) In case the Company shall, by dividend or otherwise, at any time distribute (a "TRIGGERING DISTRIBUTION") to all or substantially all holders of its Common Stock cash in an aggregate amount that, together with the aggregate amount of (A) any cash and the fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of any tender offer by the Company or a Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 4.06 has been made and (B) all other cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 4.06 has been made, exceeds an amount equal to 10.0% of the product of the current market price per share of Common Stock (as determined in accordance with subsection (g) of this Section 4.06) on the Business Day (the "DETERMINATION DATE") immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying such Conversion Price in effect immediately prior to the Determination Date by a fraction of which the numerator shall be the current market price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.06) on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (determined as aforesaid in this Section 4.06(d)) of any such other consideration so distributed, paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date) and the denominator shall be such current market price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.06) on the 25

31 Determination Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. (f) In case any tender offer made by the Company or any of its Subsidiaries for Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee thereof) of any other consideration) that, together with the aggregate amount of (A) any cash and the fair market value (as determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of any other tender offers by the Company or any Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Conversion Price adjustment pursuant to this Section 4.06 has been made and (B) all cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the Expiration Date and in respect of which no Conversion Price adjustment pursuant to this Section 4.06 has been made, exceeds an amount equal to 10.0% of the product of the current market price per share of Common Stock (as determined in accordance with subsection (g) of this Section 4.06) as of the last date (the "EXPIRATION DATE") tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the "EXPIRATION TIME") multiplied by the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time, then, immediately prior to the opening of business on the day after the Expiration Date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the Expiration Date by a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the current market price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.06) on the Trading Day next succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "PURCHASED SHARES") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the current market price per share of Common Stock (as determined in accordance with subsection (g) of this Section 4.06) on the Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have been in effect based upon the number of shares actually purchased. If the application of this Section 4.06(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 4.06(f). For purposes of this Section 4.06(e), the term "tender offer" shall mean and include both tender offers and exchange offers, all references to "purchases" of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of 26

32 shares pursuant to exchange offers, and all references to "tendered shares" (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. (g) For the purpose of any computation under subsections (b), (c), (d) and (e) of this Section 4.06, the current market price per share of Common Stock on any date shall be deemed to be the average of the daily Closing Sale Prices for the 30 consecutive Trading Days commencing 45 Trading Days before (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under subsections (d) and (e) of this Section 4.06 or (ii) the record date with respect to distributions, issuances or other events requiring such computation under subsection (c), (d) or (e) of this Section 4.06. If no such prices are available, the current market price per share shall be the fair value of share of Common Stock as determined by the Board of Directors (which shall be evidenced by an Officers' Certificate delivered to the Trustee). (h) If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred. SECTION 4.07. NO ADJUSTMENT. No adjustment in the Conversion Price shall be required until cumulative adjustments amount to 1% or more of the Conversion Price as last adjusted; PROVIDED, HOWEVER, that any adjustments which by reason of this Section 4.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. No adjustment need be made for a change in the par value or no par value of the Common Stock. SECTION 4.08. OTHER ADJUSTMENTS. (a) In the event that, as a result of an adjustment made pursuant to Section 4.06 hereof, the Holder of any Note thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock of the Company other than shares of its Common Stock, thereafter the Conversion Price of such other shares so receivable upon conversion of any Note shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Article 4. (b) In the event that shares of Common Stock are not delivered after the expiration of any of the rights or warrants referred to in Section 4.06(b) and Section 4.06(c) hereof, the Conversion Price shall be readjusted to the Conversion Price which would otherwise be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. SECTION 4.09. ADJUSTMENTS FOR TAX PURPOSES. The Company may make such reductions in the Conversion Price, in addition to those required by Section 4.06 hereof, as it determines in its discretion to be advisable in order that any stock dividend, subdivision of shares, distribution or rights to purchase stock or securities or distribution of securities 27

33 convertible into or exchangeable for stock made by the Company to its stockholders will not be taxable to the recipients thereof. SECTION 4.10. NOTICE OF ADJUSTMENT. Whenever the Conversion Price is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Registrar's books a notice of the adjustment and file with the Trustee an Officers' Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment. Unless and until a Trust Officer of the Trustee shall receive written notice of an adjustment of the Conversion Price, the Trustee may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect. SECTION 4.11. NOTICE OF CERTAIN TRANSACTIONS. In the event that: (1) the Company takes any action which would require an adjustment in the Conversion Price; (2) the Company takes any action that would require a supplemental indenture pursuant to Section 4.12; or (3) there is a dissolution or liquidation of the Company; the Company shall mail to Holders at the addresses appearing on the Registrar's books and the Trustee a notice stating the proposed record or effective date, as the case may be, to permit a Holder of a Note to convert such Note into shares of Common Stock prior to the record date for or the effective date of the transaction in order to receive the rights, warrants, securities or assets which a holder of shares of Common Stock on that date may receive. The Company shall mail the notice at least 15 days before such date; however, failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 4.11. SECTION 4.12. EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, MERGERS OR SALES ON CONVERSION PRIVILEGE. If any of the following shall occur, namely: (i) any reclassification or change of outstanding shares of Common Stock issuable upon conversion of Notes (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination or as a result of a reincorporation of the Company in another jurisdiction), (ii) any consolidation or merger to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination) in, outstanding shares of Common Stock or (iii) any sale or conveyance of all or substantially all of the property or business of the Company as an entirety, then the Company, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee providing that the Holder of each Note then outstanding shall have the right to convert such Note into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, sale or conveyance by a Holder of the number of shares of Common Stock 28

34 deliverable upon conversion of such Note immediately prior to such reclassification, change, consolidation, merger, sale or conveyance. In the event that the shares of Common Stock are exchanged or substituted for other securities in connection with any such reclassification, change, consolidation, merger, sale or conveyance, such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 4. If, in the case of any such consolidation, merger, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a Holder of Common Stock includes shares of stock or other securities and property of a corporation other than the successor or purchasing corporation, as the case may be, in such consolidation, merger, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors of the Company shall reasonably consider necessary by reason of the foregoing. The provision of this Section 4.12 shall similarly apply to successive consolidations, mergers, sales or conveyances. In the event the Company shall execute a supplemental indenture pursuant to this Section 4.12, the Company shall promptly file with the Trustee an Officers' Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Notes upon the conversion of their Notes after any such reclassification, change, consolidation, merger, sale or conveyance and any adjustment to be made with respect thereto. SECTION 4.13. TRUSTEE'S DISCLAIMER. The Trustee has no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.10 hereof. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article 4. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.12, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.12 hereof. SECTION 4.14. VOLUNTARY REDUCTION. The Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during the period if the Board of Directors determines that such reduction would be in the best interest of the Company and the Company provides 15 days prior notice of any reduction in the Conversion Price; provided, however, that in no event may the Company reduce the Conversion Price to be less than the par value of a share of Common Stock. 29

35 ARTICLE 5. SUBORDINATION SECTION 5.01. AGREEMENT TO SUBORDINATE. The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes (including the principal of, premium, if any, and interest (including Additional Interest, if any) on all the Notes and the redemption price and Make-Whole Payment, if any, with respect to any Notes being called for redemption and the Change in Control Payment with respect to all Notes subject to purchase pursuant to Section 6.09 hereof) is subordinated in right of payment, to the extent and in the manner provided in this Article 5, to the prior payment in full of all Senior Indebtedness (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Indebtedness. No provision of this Section 5 shall prevent the occurrence of any Default or Event of Default. SECTION 5.02. LIQUIDATION; DISSOLUTION; BANKRUPTCY. Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company's assets and liabilities: (i) holders of Senior Indebtedness shall be entitled to receive payment in full of all Obligations due in respect of such Senior Indebtedness (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Indebtedness) before Holders of the Notes shall be entitled to receive any payment with respect to the Notes (except that Holders may receive Permitted Junior Securities); and (ii) until all Obligations with respect to Senior Indebtedness (as provided in clause (i) above) are paid in full, any distribution to which Holders would be entitled but for this Article 5 shall be made to holders of Senior Indebtedness (except that Holders of Notes may receive Permitted Junior Securities), as their interests may appear. SECTION 5.03. DEFAULT ON DESIGNATED SENIOR INDEBTEDNESS. (a) The Company may not make any payment or distribution to the Trustee or any Holder in respect of Obligations with respect to the Notes and may not acquire from the Trustee or any Holder any Notes for cash or property (other than Permitted Junior Securities) until all principal and other Obligations with respect to the Senior Indebtedness have been paid in full if: (i) a default in the payment of any principal or other Obligations with respect to Designated Senior Indebtedness occurs and is continuing beyond any applicable grace period in the agreement, indenture or other document governing such Designated Senior Indebtedness; or (ii) a default, other than a payment default, on Designated Senior Indebtedness occurs and is continuing that then permits holders of the Designated Senior Indebtedness to accelerate its maturity and the Trustee receives a notice of the default (a "PAYMENT BLOCKAGE NOTICE") from a Person who may give it pursuant to Section 5.12 hereof. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until (A) at least 360 days shall have elapsed since 30

36 the issuance of the immediately prior Payment Blockage Notice and (B) all scheduled payments of principal, premium, if any, and interest on the Notes that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been waived for a period of not less than 180 days. (b) The Company may and shall resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: (i) the date upon which the Trustee receives notice from the Company that the default is cured or waived or ceases to exist, or (ii) in the case of a default referred to in clause (ii) of Section 5.04(a) hereof, 179 days pass after the Payment Blockage Notice is received if the maturity of such Designated Senior Indebtedness has not been accelerated, if this Article 5 otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. SECTION 5.04. ACCELERATION OF NOTES. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the acceleration. SECTION 5.05. WHEN DISTRIBUTION MUST BE PAID OVER. In the event that the Trustee or any Holder receives any payment of any Obligations or distribution of assets of the Company of any kind or character (other than Permitted Junior Securities pursuant to Section 5 hereof),whether in cash, property or securities (including, without limitation, by way of setoff or otherwise) with respect to the Notes at a time when the Trustee or such Holder, as applicable, has actual knowledge that such payment is prohibited by Section 5.03 hereof, such payment shall be held by the Trustee or such Holder, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to, the holders of Senior Indebtedness as their interests may appear or their Representative under the indenture or other agreement (if any) pursuant to which Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all Obligations with respect to Senior Indebtedness remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article 5, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Holders or the Company or any other Person money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 5, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. 31

37 SECTION 5.06. NOTICE BY COMPANY. The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Notes to violate this Article 5, but failure to give such notice shall not affect the subordination of the Notes to the Senior Indebtedness as provided in this Article 5. SECTION 5.07. SUBROGATION. After all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of the Senior Indebtedness and until the Notes are paid in full, Holders of Notes shall be subrogated (equally and ratably with all other Indebtedness PARI PASSU with the Notes and entitled to similar rights of subrogation) to the rights of holders of Senior Indebtedness to receive payments or distributions applicable to Senior Indebtedness to the extent that payments or distributions otherwise payable to the Holders of Notes have been applied to the payment of Senior Indebtedness. A distribution made under this Article 5 to holders of Senior Indebtedness that otherwise would have been made to Holders of Notes (whether by the Company, any Holder, the Trustee or otherwise) is not, as between the Company and Holders, a payment by the Company on the Notes. SECTION 5.08. RELATIVE RIGHTS. This Article 5 defines the relative rights of Holders of Notes and holders of Senior Indebtedness. Nothing in this Indenture shall: (i) impair, as between the Company and Holders of Notes, the obligation of the Company, which is absolute and unconditional, to pay principal of, premium, if any, and interest (including Additional Interest) on the Notes in accordance with their terms; (ii) affect the relative rights of Holders of Notes and creditors of the Company other than their rights in relation to holders of Senior Indebtedness; or (iii) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Indebtedness to receive distributions and payments otherwise payable to Holders of Notes. If the Company fails because of this Article 5 to pay principal of, premium, if any, or interest (including Additional Interest) on a Note on the due date, the failure is still a Default or Event of Default. SECTION 5.09. SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY. No right of any holder of Senior Indebtedness to enforce the subordination of the Indebtedness evidenced by the Notes shall be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any Holder to comply with this Indenture. SECTION 5.10. DISTRIBUTION OR NOTICE TO REPRESENTATIVE. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative. 32

38 Upon any payment or distribution of assets of the Company referred to in this Article 5, the Trustee and the Holders of Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 5. SECTION 5.11. RIGHTS OF TRUSTEE AND PAYING AGENT. Notwithstanding the provisions of this Article 5 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless the Trustee shall have received at its Corporate Trust Office at least five Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article 5. Only the Company or a Representative may give the notice. Nothing in this Article 5 shall impair the claims of, or payments to, the Trustee under or pursuant to Section 9.07 hereof. The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. SECTION 5.12. AUTHORIZATION TO EFFECT SUBORDINATION. Each Holder of Notes, by the Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 5, and appoints the Trustee to act as such Holder's attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 8.09 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Designated Senior Indebtedness are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes. SECTION 5.13. AMENDMENTS. The provisions of this Article 5 shall not be amended or modified without the written consent of the holders of all Senior Indebtedness. SECTION 5.14. AGREEMENT TO SUBORDINATE UNAFFECTED. The provisions of this Article 5 shall remain in full force and effect irrespective of (a) any amendment, modification, or supplement of, or any waiver or consent to, any of the terms of the Senior Indebtedness or the agreement or instrument governing the Senior Indebtedness, (b) the release or non-perfection of any collateral securing the Senior Indebtedness or (c) the manner of sale or other disposition of the collateral securing the Senior Indebtedness or the application of the proceeds upon such sale. SECTION 5.15. CERTAIN CONVERSIONS DEEMED PAYMENT. For the purposes of this Article 5 only, (1) the issuance and delivery of Permitted Junior Securities upon conversion of Notes in accordance with Article 4 shall not be deemed to constitute a 33

39 payment or distribution on account of the principal of, or premium, if any, or interest (including Additional Interest) on the Notes or on account of the purchase or other acquisition of Notes, and (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 4.03), property or securities (other than Permitted Junior Securities) upon conversion of a Note shall be deemed to constitute payment on account of the principal of such Note. Nothing contained in this Article 5 or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders, the right, which is absolute and unconditional, of the Holder of any Note to convert such Note in accordance with Article 4. ARTICLE 6. COVENANTS SECTION 6.01. PAYMENT OF NOTES. The Company shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. The Company shall pay all Additional Interest, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate borne by the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest (without regard to any applicable grace period) at the same rate to the extent lawful. SECTION 6.02. MAINTENANCE OF OFFICE OR AGENCY. The Company shall maintain in the Borough of Manhattan, the City of New York, a Paying Agent, Conversion Agent, Registrar and an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; PROVIDED, HOWEVER, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03. 34

40 SECTION 6.03. REPORTS. Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company shall furnish to the Holders of Notes (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report thereon by the Company's certified independent accountants and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in each case, within the time periods specified in the SEC's rules and regulations; provided, that if the Company files the reports required by this Section 6.03 with the SEC and such reports are publicly available, it shall be deemed to have satisfied its obligation to furnish such reports to the Holders pursuant to this Section 6.03. The Company shall at all times comply with TIA ss. 314(a). SECTION 6.04. RULE 144A INFORMATION REQUIREMENT. Within the period prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make available to any Holder or beneficial holder of Notes or any Common Stock issued upon conversion thereof which continue to be Restricted Notes in connection with any sale thereof and any prospective purchaser of Notes or such Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any Holder or beneficial holder of the Notes or such Common Stock and it will take such further action as any Holder or beneficial holder of such Notes or such Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Notes or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the request of any Holder or any beneficial holder of the Notes or such Common Stock, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. SECTION 6.05. COMPLIANCE CERTIFICATE. (a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers' Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. (b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers' Certificate 35

41 specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. SECTION 6.06. TAXES. The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. SECTION 6.07. STAY, EXTENSION AND USURY LAWS. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. SECTION 6.08. CORPORATE EXISTENCE. Subject to Article 7 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; PROVIDED, HOWEVER, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. SECTION 6.09. OFFER TO REPURCHASE UPON CHANGE OF CONTROL. (a) Upon the occurrence of a Change of Control, the Company shall make an offer (a "CHANGE OF CONTROL OFFER") to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a purchase price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest thereon, if any, to, but excluding, the date of purchase (the "CHANGE OF CONTROL PAYMENT"). Within 10 business days following any Change of Control, the Company shall mail a notice to each Holder stating: (1) that the Change of Control Offer is being made pursuant to this Section 6.09 and that all Notes tendered will be accepted for payment; (2) the purchase price and the purchase date, which shall be 30 business days after the occurrence of a Change of Control (the "CHANGE OF CONTROL PAYMENT DATE"); (3) that any Note not tendered will continue to accrue interest; (4) the name and address of each Paying Agent and Conversion Agent, (5) the Conversion Price and any adjustments thereto, (6) that Notes as to which a Change in Control Payment Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture only to the extent that the Change in Control Payment Notice has been withdrawn in accordance with the terms of this Indenture, (7) that, unless the Company defaults in the payment of the 36

42 Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date; (8) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the Business Day preceding the Change of Control Payment Date; (9) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission, letter or any other written form setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and (10) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. The Company shall comply with the requirements of Rule 13e-4 and Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes in connection with a Change of Control. A "Change in Control" shall be deemed to have occurred if any of the following occurs after the date hereof: (i) any "person" or "group" (as such terms are defined below) is or becomes the "beneficial owner" (as defined below), directly or indirectly (other than as a direct result of repurchases of stock by the Company), of shares of Voting Stock of the Company representing 50% or more of the total voting power of all outstanding classes of Voting Stock of the Company or such person or group (other than the "management group") has the power, directly or indirectly, to elect a majority of the members of the Board of Directors of the Company; provided, that Voting Stock acquired in an exempt transaction shall not constitute a Change in Control, or (ii) the Company consolidates with, or merges with or into, another Person or the Company sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of the assets of the Company, or any Person consolidates with, or merges with or into, the Company, in any such event other than (a) pursuant to a transaction in which the Persons that "beneficially owned" (as defined below), directly or indirectly, shares of Voting Stock of the Company immediately prior to such transaction "beneficially own" (as defined below), directly or indirectly, shares of Voting Stock of the Company representing at least a majority of the total voting power of all outstanding classes of Voting Stock of the surviving or transferee Person or (b) an exempt transaction; or (iii) there shall occur the liquidation or dissolution of the Company. For the purpose of the definition of "Change in Control", (i) "person" and "group" have the meanings given such terms under Section 13(d) and 14(d) of the Exchange Act or any successor provision to either of the foregoing, and the term "group" includes any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor provision thereto), (ii) a "beneficial owner" shall be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the date of this Indenture, except that the number of shares of Voting Stock of the Company shall be deemed to include, in addition to all outstanding shares of Voting Stock of the Company and Unissued Shares deemed to be held by the "person" or "group" (as 37

43 such terms are defined above) or other Person with respect to which the Change in Control determination is being made, all Unissued Shares deemed to be held by all other Persons, and (iii) the terms "beneficially owned" and "beneficially own" shall have meanings correlative to that of "beneficial owner". The term "Unissued Shares" means shares of Voting Stock not outstanding that are subject to options, warrants, rights to purchase or conversion privileges exercisable within 60 days of the date of determination of a Change in Control. The term "exempt transaction" means any purchase from the Company of equity interests in the Company by the management group; provided that the management group does not collectively beneficially own more than 65% of the total Voting Stock of all outstanding classes of Voting Stock of the Company following such purchase. The term "management group" means any of Thomas Russell, The AER 1997 Trust, Robert Louis-Dreyfus, Gallium Enterprises, Inc. and Reuben Richards. Notwithstanding anything to the contrary set forth in this Section 6.09, a Change in Control will not be deemed to have occurred if either: (i) the Closing Sale Price of the Common Stock for any five Trading Days during the period of the ten Trading Days immediately preceding the Change in Control is at least equal to 105% of the Conversion Price in effect on such day; or (ii) in the case of a merger or consolidation, all of the consideration (excluding cash payments for fractional shares in the merger or consolidation constituting the Change in Control) consists of common stock traded on a United States national securities exchange or quoted on The Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such Change In Control) and as a result of such transaction or transactions the Notes become convertible solely into such common stock. (b) A Holder may exercise its rights pursuant to this Section 6.09 upon delivery of a written notice (which shall be in substantially the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Notes, may be delivered electronically or by other means in accordance with the Depositary's customary procedures) of the exercise of such rights (a "CHANGE IN CONTROL PAYMENT NOTICE") to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date. Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Change in Control Payment Notice contemplated by this Section 6.09(b) shall have the right to withdraw such Change in Control Payment Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of business on the Business Day next preceding the Change in Control Payment Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 6.09(a) hereof. Upon receipt by any Paying Agent of the Change in Control Payment Notice specified in this Section 6.09(b), the Holder of the Security in respect of which such Change in Control Payment Notice was given shall (unless such Change in Control Payment Notice is withdrawn as specified below) thereafter be entitled to receive the Change in Control Payment Price with respect to such Note. Such Change in Control Payment Price shall be paid to such Holder promptly following the later of (i) the Change in Control Payment Date with respect to such Note (provided the conditions in this Section 6.09(b) have been satisfied) and (ii) the time of delivery of such Note to a Paying Agent by the Holder thereof in the manner required by this Section 6.09(b). Notes in respect of which a Change in Control 38

44 Payment Notice has been given by the Holder thereof may not be converted into shares of Common Stock on or after the date of the delivery of such Change in Control Payment Notice unless such Change in Control Payment Notice has first been validly withdrawn. (c) On the Change of Control Payment Date, the Company shall, to the extent lawful, (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered and (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of Notes so tendered payment in an amount equal to the purchase price for the Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered by such Holder, if any; PROVIDED, that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Change in Control Payment Price of any Note for which a Change in Control Payment Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Change in Control Payment Date, such Note will cease to be outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Change in Control Payment Price as aforesaid). (d) Notwithstanding anything to the contrary in this Section 6.09, the Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 6.09 hereof and all other provisions of this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. SECTION 6.10. PAYMENT OF ADDITIONAL INTEREST. If Additional Interest is payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee a certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. ARTICLE 7. SUCCESSORS SECTION 7.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS. The Company shall not, directly or indirectly, consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, another Person unless (i) the Company is the surviving corporation or the Person formed by or surviving any such 39

45 consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia, (ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Registration Rights Agreement, the Notes and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee, (iii) immediately after such transaction, no Default or Event of Default exists and (iv) the Company or the surviving corporation, as the case may be, shall have delivered to the Trustee and Officers' Certificate and an Opinion of Counsel, each stating that such merger, consolidation, conveyance, transfer or lease comply with this Article Seven and that all conditions precedent herein provided for relating to such transaction have been satisfied. SECTION 7.02. SUCCESSOR CORPORATION SUBSTITUTED. Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 7.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the "Company" shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; PROVIDED, HOWEVER, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale, assignment, transfer, conveyance or other disposition of all of the Company's assets that meets the requirements of Section 7.01 hereof. ARTICLE 8. DEFAULTS AND REMEDIES SECTION 8.01. EVENTS OF DEFAULT. An "Event of Default" occurs if: (a) the Company defaults in the payment when due of interest on, or Additional Interest with respect to, the Notes and such default continues for a period of 30 days; (b) the Company defaults in the payment when due of principal of or premium, if any, on the Notes when the same becomes due and payable at maturity, upon redemption (including in connection with an offer to purchase) or otherwise; (c) the Company fails to comply with any of the provisions of Section 6.09 hereof; (d) the Company fails to observe or perform any other covenant, representation, warranty or other agreement in this Indenture or the Notes for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class; 40

46 (e) the Company fails to provide timely notice of a Change of Control; (f) the Company: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a custodian of it or for all or substantially all of its property, (iv) makes a general assignment for the benefit of its creditors, or (v) generally is not paying its debts as they become due; or (g) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company in an involuntary case; (ii) appoints a custodian of the Company or for all or substantially all of the property of the Company; or (iii) orders the liquidation of the Company; and the order or decree remains unstayed and in effect for 60 consecutive days. SECTION 8.02. ACCELERATION. If any Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 8.01 hereof with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (g) or (h) of Section 8.01 hereof occurs with respect to the Company, all outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. SECTION 8.03. OTHER REMEDIES. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or 41

47 constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 8.04. WAIVER OF PAST DEFAULTS. Subject to Section 8.02, Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest, if any, or interest on, the Notes (including in connection with an offer to purchase) or a failure by the Company to convert any Notes into Common Stock (PROVIDED, HOWEVER, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. SECTION 8.05. CONTROL BY MAJORITY. Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. SECTION 8.06. LIMITATION ON SUITS. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. SECTION 8.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on or 42

48 after the respective due dates expressed in the Note (including in connection with an offer to purchase), to convert such Note in accordance with Article 4 or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 8.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 8.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 8.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 8.10. PRIORITIES. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: FIRST: to the Trustee, its agents and attorneys for amounts due under Section 9.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; SECOND: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of 43

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 8.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. ARTICLE 9. TRUSTEE SECTION 9.01. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. (b) Except during the continuance of an Event of Default: (i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section; 44

50 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 7.05 hereof.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 9.02. RIGHTS OF TRUSTEE. (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. (c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. (g) The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes unless either (1) a Responsible Officer shall have actual 45

51 knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company of by any Holder of the Notes. SECTION 9.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 9.10 and 9.11 hereof. SECTION 9.04. TRUSTEE'S DISCLAIMER. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company's use of the proceeds from the Notes or any money paid to the Company or upon the Company's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. SECTION 9.05. NOTICE OF DEFAULTS. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. SECTION 9.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES. Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA ss. 313(a) (but if no event described in TIA ss. 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA ss. 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA ss. 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA ss. 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. SECTION 9.07. COMPENSATION AND INDEMNITY. The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by 46

52 any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company shall indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 9.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Company under this Section 9.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 8.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to the extent applicable. SECTION 9.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 9.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (c) a custodian or public officer takes charge of the Trustee or its property; or 47

53 (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 9.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, PROVIDED all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 9.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 9.08, the Company's obligations under Section 9.07 hereof shall continue for the benefit of the retiring Trustee. SECTION 9.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. SECTION 9.10. ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA ss. 310(b). SECTION 9.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The Trustee is subject to TIA ss. 311(a), excluding any creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to the extent indicated therein. 48

54 ARTICLE 10. SATISFACTION AND DISCHARGE SECTION 10.01. SATISFACTION AND DISCHARGE. This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: (1) either: (a) all Notes that have been authenticated (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation; or (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise or will become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Additional Interest, if any, and accrued interest to the date of maturity or redemption; (2) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound; (3) the Company has paid or caused to be paid all sums payable by it under this Indenture; and (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officers' Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 10.02 shall survive. SECTION 10.02. APPLICATION OF TRUST MONEY. All money deposited with the Trustee pursuant to Section 10.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose 49

55 payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 10.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01; PROVIDED that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. SECTION 10.03. REPAYMENT TO COMPANY. The Trustee and each Paying Agent shall promptly pay to the Company upon request any excess money (i) deposited with them pursuant to Section 10.1 and (ii) held by them at any time. The Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors. SECTION 10.04. REINSTATEMENT. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 10.2 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.1 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 10.2; provided, however, that if the Company has made any payment of the principal of or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive any such payment from the money held by the Trustee or such Paying Agent. ARTICLE 11. AMENDMENT, SUPPLEMENT AND WAIVER SECTION 11.01. WITHOUT CONSENT OF HOLDERS OF NOTES. Notwithstanding Section 11.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: (a) to cure any ambiguity, defect or inconsistency; 50

56 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; (c) to provide for the assumption of the Company's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 7 hereof; (d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note; (e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; or (f) to provide for the issuance of additional Notes pursuant to the purchasers option set forth in the Purchase Agreement. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 9.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. SECTION 11.02. WITH CONSENT OF HOLDERS OF NOTES. Except as provided below in this Section 11.02, the Company and the Trustee may amend or supplement this Indenture (including Section 6.09 hereof) and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 8.04 and 8.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be "outstanding" for purposes of this Section 11.02. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. 51

57 It shall not be necessary for the consent of the Holders of Notes under this Section 11.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 8.04 and 8.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 11.02 may not (with respect to any Notes held by a non-consenting Holder): (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; (b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Section 6.09 hereof; (c) reduce the rate of or change the time for payment of interest, including default interest, on any Note; (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); (e) make any Note payable in money other than that stated in the Notes; (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or interest on the Notes; or (g) make any change in Section 8.04 or 8.07 hereof or in the foregoing amendment and waiver provisions. SECTION 11.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect. SECTION 11.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, 52

58 supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. SECTION 11.05. NOTATION ON OR EXCHANGE OF NOTES. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. SECTION 11.06. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article Nine if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 9.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

5 [REVERSE SIDE OF SECURITY] EMCORE CORPORATION 5% CONVERTIBLE SUBORDINATED NOTES DUE 2006 1. INTEREST EMCORE Corporation, a New Jersey corporation (the "Company", which term shall include any successor corporation under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Note at the rate of 5% per annum. The Company shall pay interest semiannually on May 15 and November 15 of each year, commencing November 15, 2001, unless such date is not a business day, in which case, we shall pay interest on the next succeeding business day and such payment shall be deemed to have been paid on such interest payment date and no interest shall accrue during the additional period of time. Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from May 7, 2001; provided, however, that if there is not an existing default in the payment of interest and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Any reference herein to interest accrued or payable as of any date shall include any Additional Interest accrued or payable on such date as provided in the Registration Rights Agreement. 2. METHOD OF PAYMENT The Company shall pay interest on this Note (except defaulted interest) to the person who is the Holder of this Note at the close of business on May 1 or November 1, as the case may be, next preceding the related interest payment date. The Holder must surrender this Note to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may, however, pay principal and interest in respect of any Definitive Note by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder. The Company may mail an interest check to the Holder's registered address. Notwithstanding the foregoing, so long as this Note is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 3. PAYING AGENT, REGISTRAR AND CONVERSION AGENT Initially, Wilmington Trust Company, (the "Trustee," which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar. 4. INDENTURE, LIMITATIONS This Note is one of a duly authorized issue of Notes of the Company designated as its 5% Convertible Subordinated Notes due 2006 (the "Notes"), issued under an Indenture dated as of May 7, 2001 (together with any supplemental indentures thereto, the "Indenture"), between the Company and 5

6 the Trustee. The terms of this Note include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Note is subject to all such terms, and the Holder of this Note is referred to the Indenture and said Act for a statement of them. All capitalized terms used but not defined herein shall have the meaning ascribed to such term in the Indenture. The Notes are subordinated unsecured obligations of the Company limited to $175,000,000 aggregate principal amount, subject to Section 2.2 of the Indenture. The Indenture does not limit other debt of the Company, secured or unsecured, including Senior Indebtedness. 5. PROVISIONAL AND OPTIONAL REDEMPTION The Notes may be redeemed at the election of the Company, as a whole or in part from time to time, at any time prior to May 20, 2004 (a "PROVISIONAL REDEMPTION"), upon at least 20 and not more than 60 days' notice by mail to the Holders of the Notes at a redemption price equal to $1,000 per $1,000 principal amount of the Notes redeemed plus accrued and unpaid interest, if any (such amount, together with the Make-Whole Payment described below, the "PROVISIONAL REDEMPTION PRICE"), to but excluding the date of redemption (the "PROVISIONAL REDEMPTION DATE") if (1) the Closing Sale Price of the Common Stock has exceeded 150% of the Conversion Price for at least 20 Trading Days within a period of any 30 consecutive Trading Days ending on the Trading Day prior to the date of mailing of the notice of Provisional Redemption (the "NOTICE DATE"), and (2) a shelf registration statement covering resales of the Notes and the Common Stock issuable upon conversion thereof is effective and available for use and is expected to remain effective and available for use for the 30 days following the Provisional Redemption Date unless registration is no longer required. Upon any such Provisional Redemption, the Company, shall make an additional payment, at its option, in cash or Common Stock or a combination of cash and Common Stock (the "MAKE-WHOLE PAYMENT") with respect to the Notes called for redemption to holders on the Notice Date in an amount equal to $150.00 per $1,000 principal amount of the Notes, less the amount of any interest actually paid (including, if the Provisional Redemption Date occurs after a record date but before an interest payment date, any interest paid or payable in connection with such interest payment date) on such Notes prior to the Provisional Redemption Date. Payments made in Common Stock will be valued at 97% of the average closing sales prices of Common Stock for the five Trading Days ending on the day prior to the Redemption Date. The Company shall make the Make-Whole Payment on all Notes called for Provisional Redemption, including those Notes converted into Common Stock between the Notice Date and the Provisional Redemption Date. Except as set forth above, the Notes are subject to redemption, at any time on or after May 20, 2004, on at least 20 days and no more than 60 days notice, in whole or in part, at the election of the Company. The Redemption Prices (expressed as percentages of the principal amount) are as follows for Notes redeemed during the periods set forth below: Period Redemption Price ------ ---------------- May 20, 2004 through May 14, 2005........................ 101.25% May 15, 2005 and thereafter.............................. 100.00% 6

7 in each case together with accrued interest up to but not including the Redemption Date; provided that if the redemption date is an interest payment date, interest will be payable to the Holders in whose names the Notes are registered at the close of business on the relevant record dates. 6. NOTICE OF REDEMPTION Notice of redemption will be mailed by first-class mail at least 20 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part, but only in whole multiples of $1,000. On and after the Redemption Date, subject to the deposit with the Paying Agent of funds sufficient to pay the Redemption Price plus accrued interest, if any, accrued to, but not including, the Redemption Date, interest shall cease to accrue on Notes or portions of them called for redemption. 7. PURCHASE OF NOTES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Notes held by such Holder on the date that is 30 Business Days after the occurrence of a Change in Control, at a purchase price equal to 100% of the principal amount thereof together with accrued interest up to, but excluding, the Change in Control Purchase Date. The Holder shall have the right to withdraw any Change in Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 8. CONVERSION A Holder of a Note may convert the principal amount of such Note (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of Common Stock at any time prior to the close of business on May 15, 2006; provided, however, that if the Note is called for redemption or subject to purchase upon a Change in Control, the conversion right will terminate at the close of business on the Business Day immediately preceding the redemption date or the Change in Control Purchase Date, as the case may be, for such Note or such earlier date as the Holder presents such Note for redemption or purchase (unless the Company shall default in making the redemption payment or Change in Control Purchase Price, as the case may be, when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Note is redeemed or purchased). The initial Conversion Price is $48.7629 per share, subject to adjustment under certain circumstances. The number of shares of Common Stock issuable upon conversion of a Note is determined by dividing the principal amount of the Note or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the closing price (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to the Conversion Date. To convert a Note, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Note to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a 7

8 Conversion Agent, and (d) pay any transfer or similar tax, if required. Notes so surrendered for conversion (in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next succeeding interest payment date (excluding Notes or portions thereof called for redemption or subject to purchase upon a Change in Control on a Redemption Date or Change in Control Purchase Date, as the case may be, during the period beginning at the close of business on a regular record date and ending at the opening of business on the first Business Day after the next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such interest payment date on the principal amount of such Note then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such Note, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly repay such funds to such Holder. A Holder may convert a portion of a Note equal to $1,000 or any integral multiple thereof. A Note in respect of which a Holder had delivered a Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Note may be converted only if the Change in Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 9. SUBORDINATION The indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to the prior payment in full in cash of all Senior Indebtedness. Any Holder by accepting this Note agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect. In addition to all other rights of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any terms of any instrument relating to the Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 10. DENOMINATIONS, TRANSFER, EXCHANGE The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 11. PERSONS DEEMED OWNERS The Holder of a Note may be treated as the owner of it for all purposes. 12. UNCLAIMED MONEY If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to money must look to the Company for payment. 8

9 13. AMENDMENT, SUPPLEMENT AND WAIVER Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Notes may be waived in a particular instance with the consent of the Holders of a majority in principal amount of the Notes then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 14. SUCCESSOR CORPORATION When a successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation will (except in certain circumstances specified in the Indenture) be released from those obligations. 15. DEFAULTS AND REMEDIES Under the Indenture, an Event of Default includes: (i) default for 30 days in payment of any interest on any Notes; (ii) default in payment of any principal (including, without limitation, any premium, if any) on the Notes when due; (iii) failure by the Company for 60 days after notice to it to comply with any of its other agreements contained in the Indenture or the Notes; (iv) we fail to comply with any of the provisions of Section 6.09 of the Indenture; (v) we fail to provide timely notice of a change in control; and (vi) certain events of bankruptcy, insolvency or reorganization of the Company. If an Event of Default (other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding may declare all unpaid principal to the date of acceleration on the Notes then outstanding to be due and payable immediately, all as and to the extent provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid principal of the Notes then outstanding shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the absence of default. 16. TRUSTEE DEALINGS WITH THE COMPANY Wilmington Trust Company, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 9

10 17. NO RECOURSE AGAINST OTHERS A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Notes or the Indenture nor for any claim based on, in respect of or by reason of such obligations or their creation. The Holder of this Note by accepting this Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Note. 18.

11 Existing Agreement shall be refinanced with Revolving Loans incurred hereunder, and (iii) the obligations of the Borrower with respect to such existing revolving loans evidenced by the Revolving Note issued under the Existing Agreement shall be deemed to be evidenced by the Revolving Note issued hereunder. It is the intention of the parties hereto that the amendment, restatement and refinancing of the existing revolving loan commitment under the Existing Agreement with the Revolving Loan Commitment herein provided shall be deemed to be a modification of the Borrower's obligations thereunder and not an extinguishment or novation thereof. 2.2.

Subject to the satisfaction of the conditions set forth in Sections 2.1 and 2.4, the Bank shall lend to Borrower the amount specified in such Borrowing Notice, provided, however, that each Revolving Loan shall be made only on a Business Day. In the event that any Borrowing Notice is given to the Bank by telephone, such notice must be confirmed by the Borrower via same day facsimile. All Revolving Loans shall be credited to an account of the Borrower maintained by the Bank. 2.3. Borrowing Warranty.

Borrowing Conditions. Notwithstanding anything contained in this Agreement to the contrary, the Bank shall have no obligation to make any Revolving Loan if an Event of Default or Unmatured Event of Default (a) shall exist on the date of such proposed borrowing or (b) shall result from the making of such Revolving Loan. 2.5. Procedures for Letters of Credit. (A) Issuance of Letters of Credit. Within the Available Commitment, until the Commitment Expiration Date, and provided that no Event of Default shall have occurred and be continuing or would result from the issuance of a Letter of Credit and subject to the limitations of Section 2.1, the Bank may issue Letters of Credit for the account of Borrower on the terms hereinafter set forth. No Letter of Credit shall have a term in excess of 365 days and, in any event, an expiry date beyond the Commitment Expiration Date. Each of the Letters of Credit shall be issued in a form satisfactory to the Bank and pursuant to a Letter of Credit Agreement duly executed by the Borrower.

If the Borrower shall not so reimburse the Bank as provided above, such failure shall be an Event of Default and the Borrower shall pay to the Bank interest on the amount of such payment from the date of such payment by the Bank or the failure of the Borrower to so reimburse the Bank, as applicable, through and including the date of such reimbursement by the Borrower at the Default Rate. (C) Letter of Credit Obligations Absolute.

12 Letter of Credit, the Bank or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction; (iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (v) payment by the Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit; and (vi) any other act or omission to act or delay of any kind of the Bank, or any other person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this section, constitute a legal or equitable discharge of the Borrower's obligations hereunder.

(D) Outstanding Letter of Credit Obligations. In addition to the provisions of this Section 2.5 (B), upon an Event of Default, the full amount of all Letter of Credit Obligations shall be deemed to increase the principal amount deemed outstanding under as Revolving Loans (and any unpaid interest thereon and on unpaid letter of credit fees shall be deemed principal of a Revolving Loan), for purposes of (x) distribution of payments hereunder and (y) application of proceeds realized upon the exercise of remedies hereunder or under any Loan Document; provided, however, if any such Letter of Credit thereafter expires without being drawn upon, the amount thereof shall reduce the principal amount deemed outstanding under the Revolving Loans (as previously increased pursuant to this subsection (D)) and the distributions of payments and proceeds to the Bank shall be adjusted accordingly. 2.6. Issuance Warranty. Each request for a Letter of Credit pursuant to Section 2.5(A) shall constitute a warranty and representation to the Bank that, as of the date of such request and the date of the issuance of any such Letter of Credit, all of the following are true and correct: (a) the representations and warranties of the Borrower set forth in Section 8 below are true and correct, (b) the covenants of the Borrower set forth in Section 10 below have been complied with and are true and correct, and (c) no Event of Default or Unmatured Event of Default shall have occurred or will result from the issuance of any such Letter of Credit described in or the transaction for which such Letter of Credit is being issued. 2.7.

SECTION 3. NOTE EVIDENCING REVOLVING LOANS 3.1. Promissory Note. The Revolving Loans shall be evidenced by an Amended and Restated Secured Revolving Note (the "Revolving Note"), executed on and dated the date hereof, in the principal amount of up to $20,000,000 made by the Borrower in favor of the Bank. The outstanding principal balance of the Revolving Note plus all accrued and unpaid interest shall be due and payable on the Revolving Loan Maturity Date. 3.2. Recordkeeping. The Bank shall record, in accordance with its usual and customary practices, the date and amount of each Revolving Loan, and the interest rate. The Bank may, at its option, record such information on the schedule attached to the Revolving Note. The Bank's records (including such schedule) shall be presumptive evidence of the subject matter thereof. The Bank's failure to so record any such amount or any error in so recording any such amount shall not limit or otherwise affect the Obligations or any part thereof. 9

13 SECTION 4. INTEREST; ADMINISTRATION OF REVOLVING LOANS 4.1. Interest Rate. With respect to each Revolving Loan, the Borrower promises to pay interest on the unpaid principal amount thereof for the period commencing on the date of such Revolving Loan until such Revolving Loan is paid in full at a rate per annum equal to the Lending Rate. Notwithstanding anything contained in this Agreement or the Revolving Note to the contrary, with respect to each Revolving Loan, after the Revolving Loan Maturity Date on upon the occurrence and during the continuance of an Event of Default, the Borrower shall pay interest to the Bank at a rate per annum equal to the Default Rate. 4.2. Payment of Interest. Interest on each of the Revolving Loans shall be payable monthly, in arrears, on the first Business Day of each calendar month and on the Revolving Loan Maturity Date. After the Revolving Loan Maturity Date (whether by acceleration or otherwise) or upon the occurrence and during the continuance of an Event of Default, accrued interest on all Revolving Loans shall be payable on demand. 4.3. Late Payment. Any payment of principal or interest not received within ten days of its due date shall be accompanied by a late charge of three percent (3%) of the amount of such payment. 4.4. Maximum Interest. In no event shall any interest to be paid hereunder exceed the maximum rate permitted by law. In the event the interest rate paid hereunder exceeds the maximum rate permitted by law, the Loan Documents (including the Revolving Note) shall automatically be deemed amended to permit interest charges at an amount equal to, but no greater than the maximum permitted by law. 4.5. Computation of Interest. The interest chargeable hereunder shall be computed on the basis of a 360-day year for the actual number of days in the interest period ("Actual/360 Computation"). The Actual/360 Computation determines the annual effective interest yield by taking the stated (nominal) interest rate for a year's period and then dividing said rate by 360 to determine the daily periodic rate to be applied for each day in the interest period. Accordingly, the Borrower acknowledges that the application of the Actual/360 Computation produces an annualized effective interest rate exceeding that of the nominal rate. SECTION 5. PREPAYMENTS 5.1. Voluntary Prepayments. Borrower may, from time to time, prepay the Revolving Loans in whole or in part, provided that each partial prepayment shall be in a minimum principal amount of $100,000 (or any integral multiple of $50,000 in excess thereof), and any prepayment of the entire principal amount of all Revolving Loans shall include accrued interest to the date of prepayment. 5.2. Mandatory Prepayments. The sum of the outstanding aggregate principal amount of the Revolving Loans plus the Letter of Credit Obligations shall not exceed the Maximum Credit at any time. Without limiting the Bank's rights to demand payment of the Obligations in accordance with the terms of this Agreement, in the event that at any time the sum of the aggregate amount of the outstanding Revolving Loans plus the Letter of Credit Obligation exceed the Maximum Amount (such excess is referred to herein as an "Overadvance"), such Overadvance shall be payable and the Borrower shall pay to the Bank the entire amount of such Overadvance (plus interest thereon) immediately upon the Bank's demand for such amounts. SECTION 6. PAYMENTS AND FEES 6.1. Making of Payments. All payments (including prepayments pursuant to Section 5 above) of principal of, or interest on, the Revolving Loans, together with all other Obligations, shall be made without set off, deduction or counterclaim in Dollars when stated to be due by the Borrower to the Bank in immediately available funds. All payments in respect of Obligations required to be made hereunder and under the other Loan Documents shall be debited by the Bank from a demand deposit account maintained by the Borrower with the Bank. The Borrower agrees that in addition to any other rights of setoff granted to the Bank in the Loan Documents, at the Bank's option, all principal, interest, fees, costs or other charges with respect to the Revolving Loans and the Loan Documents and the proceeds of any and all Revolving Loans made by the Bank to the Borrower may be charged directly to the Borrower's account maintained by the Bank; provided, that the foregoing shall not limit the recourse of the Bank to any source of funds. 6.2. Commitment Fee. [INTENTIONALLY DELETED] 6.3. Origination Fee. In consideration of the renewal and increase of the Maximum Credit contemplated herein, the Borrower shall pay to the Bank an origination fee in the amount of $50,000.00, said fee to be due and payable upon the execution and delivery of this Agreement. 6.4. Due Date. If any payment of principal or interest with respect to any Revolving Loans falls due on a day which is not a Business Day, then such date shall be extended to the next Business Day and additional interest shall 10

14 accrue and be payable for the period of such extension. 6.5. Payments in Respect of Increased Costs. In the event that the Bank shall have determined that any Requirement of Law regarding reserves, capital adequacy, special deposit or other similar requirement(s) or any change therein or in the interpretation or application thereof or compliance by the Bank with any request or directive regarding any such requirements (whether or not having the force of law, so long as the Bank reasonably believes that compliance therewith is necessary) from any central bank or Governmental Authority, does or shall have the effect of reducing the rate of return on the Bank's capital as a consequence of its Commitment or any of its obligations hereunder to a level below that which the Bank could have achieved but for such law or change or compliance (taking into consideration such Bank's policies with respect to capital adequacy or other similar requirements) by an amount deemed by the Bank in the exercise of reasonable discretion to be material, then from time to time, upon submission by the Bank to the Borrower of a written demand therefor which sets forth in reasonable detail the basis for such request and the computation of the amount requested (the amounts set forth in any such demand shall be presumptive evidence thereof, absent manifest error), the Borrower shall pay to the Bank such additional amount or amounts as will compensate the Bank for such increased cost relating to this Agreement from the date of such event, together with any late charge applicable thereto as provided in Section 4.3 hereof and thereafter such similar payments requested by the Bank on the basis set forth above.

15 latter, the "Trademarks") associated with the Collateral in connection with any foreclosure or liquidation together with the right to grant a non-exclusive sublicense, without charge, to any buyer of such Collateral for the purpose of resale.

Any representation or warranty made by the Borrower herein is breached or is false or misleading in any material respect or omits to state a material fact, or any schedule, certificate, financial statement, report, notice, or other writing furnished by the Borrower to the Bank is false or misleading in any material respect or omits to state a material fact on the date as of which the facts therein set forth are stated or certified; or (g) Defaults under other Loans. Borrower or Guarantor defaults under (i) any Contingent Obligation, loan, extension of credit, security agreement, mortgage or other agreement with respect to Indebtedness for borrowed money with the Bank or any other Person, or (ii) any material contract with any Person and such default is declared and is not cured within the time, if any, specified therefor in any agreement covering same; or (h) Collateral. If any portion of the Collateral or any other assets of Borrower or Guarantor having a value singly or in the aggregate in excess of $100,000 are attached, seized, subjected to a writ or distress or warrant, or are levied upon or come within the possession of any receiver, trustee, custodian or assignee for the benefit of creditors and the same is not terminated or dismissed within thirty (30) days or if a notice of lien, levy or assessment of record is filed against the Collateral; or (i) Judgements.

(i) if any Person shall engage in any "prohibited transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code) involving any Plan, (ii) a Reportable Event shall occur with respect to, or proceedings shall commence to have a trustee appointed, or a trustee shall be appointed, to administer or to terminate, any Multiemployer Plan, which Reportable Event or institution of proceedings or appointment of a trustee is likely to result in the termination of such Multiemployer Plan for purposes of Title IV of ERISA, and, in the case of a Reportable Event, the continuance of such Reportable Event unremedied for ten days after notice of such Reportable Event pursuant to Section 4043(a), (c) or (d) of ERISA is given and, in the case of the institution of proceedings, the continuance of such proceedings for ten days after commencement thereof, (iii) the Borrower or an ERISA Affiliate incurs a partial or complete withdrawal from a Multiemployer Plan or (iv) any other event or condition shall occur or exist, with respect to a Plan or Multiemployer 21

25 Plan; and in each case in clauses (i) through (iv) above, such event or condition, together with all other such events or conditions, if any, could subject the Borrower or any of its Subsidiaries to any tax, penalty or other liabilities in the aggregate material in relation to the business, operations, property or financial or other condition of the Borrower taken as a whole; or (k) Change of Control. There shall occur a Change of Control (as defined below). As used herein, "Change of Control" means the acquisition by any person or group of persons (within the meaning of the Securities Exchange Act of 1934, as amended, and the rules and regulation promulgated thereunder, the "Exchange Act") of beneficial ownership (within the meaning of Rule 13d-3 promulgated by the Securities and Exchange Commission, or any successor thereto, under the Exchange Act) of 50.1% or more of the issued and outstanding shares of common stock of the Borrower. 11.2. Effect of Event of Default. If any Event of Default described in Section 11.1(b) shall occur, the Revolving Loan Commitment (if not theretofore terminated) shall automatically and immediately terminate and the Revolving Note and the other Obligations and all other amounts payable under the Loan Documents shall become automatically and immediately due and payable, all without presentment, demand, protest or notice of any kind. Upon the occurrence of any Event of Default and during the continuance thereof (other than the event described in Section 11.1(b)), the Bank may declare the Commitment (if not theretofore terminated) to be terminated and may also declare the Revolving Note, the other Obligations and all other amounts payable under the Loan Documents to be due and payable, whereupon the Revolving Loan Commitment shall immediately terminate and the Revolving Note and the other Obligations shall become immediately due and payable, all without presentment, demand, protest or other notice of any kind. The Bank shall promptly advise the Borrower of any such declaration, but failure to do so shall not impair the effect of such declaration. Except as expressly provided above in this Section presentment, demand, protest and all other notices of any kind are hereby expressly waived by the Borrower. Upon the occurrence of any Event of Default and during the continuance thereof, the Bank, may, at its option, exercise any of its rights under this Agreement, the other Loan Documents or any rights and remedies of a secured party under the Uniform Commercial Code. 11.3. Remedies. Without limiting the generality of the remedies available to the Bank may, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Borrower (all and each of which demands, presentments, protests, advertisements and notices are hereby waived), upon the occurrence and during the continuance of an Event of Default, collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing) in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of the Bank or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Bank shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold. The Borrower further agrees, at the Bank's request, to assemble the Collateral and make it available to the Bank at places which the Bank shall reasonably select, whether at the Borrower's premises or elsewhere. The Bank shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Bank hereunder, including, without limitation, reasonable attorneys' fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Bank may elect; and only after such application and after the payment by the Bank of any other amount required by any provision of law, including, without limitation, any provision of the Uniform Commercial Code, need the Bank account for the surplus, if any, to the Borrower. To the extent permitted by applicable law, the Borrower waives all claims, damages and demands it may acquire against the Bank arising out of the exercise by the Bank of any of its rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Borrower shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the reasonable fees and disbursements of any attorneys employed by the Bank to collect such deficiency. 11.4. Limitation on Duties Regarding Preservation of Collateral. The Bank's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the Uniform Commercial Code or otherwise, shall be to deal with it in the same manner as the Bank deals with similar property for its own account. Neither the Bank nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Borrower or otherwise. 22

26 11.5. Cash Collateral for Letter of Credit Obligation. Without limiting the generality of any right or remedy granted to the Bank hereunder or under any other Loan Document, upon the occurrence, and during the continuance of an Event of Default; the Bank may demand that the Borrower deposit with the Bank cash collateral for the undrawn amount of any Letter of Credit then in effect pursuant to such terms as the Bank may require. In connection therewith, the Borrower shall execute and deliver such agreements, assignments, instruments, financing statement or other documentation as the Bank may deem necessary or appropriate. SECTION 12. GENERAL 12.1. Waiver; Amendments. No delay on the part of the Bank in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by the Bank of any right, power or remedy preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification or waiver of, or consent with respect to, any provision of the Loan Documents shall in any event be effective unless the same shall be in writing and signed and delivered by the Bank and the Borrower (in the case of a document to which the Borrower is a party) and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. 12.2. WAIVER OF TRIAL BY JURY. THE BORROWER WAIVES TRIAL BY JURY IN ANY ACTION, PROCEEDING, CLAIM, OR COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, WITH RESPECT TO, IN CONNECTION WITH OR ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT OR THE LOAN DOCUMENTS OR THE VALIDITY, PROTECTION, INTERPRETATION, ADMINISTRATION, COLLECTION OR ENFORCEMENT HEREOF OR THEREOF, OR ANY CLAIM OR DISPUTE HEREUNDER OR THEREUNDER. NO OFFICER OF THE BANK HAS AUTHORITY TO WAIVE, CONDITION OR MODIFY THIS PROVISION. 12.3. Arbitration. (a) Upon demand of any party hereto, whether made before or after institution of any judicial proceeding, any dispute, claim or controversy arising out of, connected with or relating to this Agreement and the other Loan Documents ("Disputes") between or among parties to this Agreement and other Loan Documents shall be resolved by binding arbitration as provided herein. Institution of a judicial proceeding by a party does not waive the right of that party to demand arbitration hereunder. Disputes may include, without limitation, tort claims, counterclaims, disputes as to whether a matter is subject to arbitration, claims bought as class actions, claims arising from Loan Documents executed in the future, or claims arising out of or connected with the transaction reflected by this Agreement and other Loan Documents. (b) Arbitration shall be conducted under and governed by the Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the American Arbitration Association (the "AAA") and Title 9 of the U.S. Code. All arbitration hearings shall be conducted in the city in which the office of the Bank first stated above is located. The expedited procedure set forth in Rule 51 et seq. of the Arbitration Rules shall be applicable to claims of less that $1,000,000. All applicable statutes of limitation shall apply to any Dispute. A judgment upon the award may be entered in any court having jurisdiction. The panel from which all arbitrators are selected shall be comprised of licensed attorneys. The single arbitrator selected for expedited procedure shall be a retired judge from the highest court of general jurisdiction, state or federal, of the state where the hearing will be conducted or if such person is not available to serve, the single arbitrator may be licensed attorney. Notwithstanding the foregoing, this arbitration provision does not apply to Disputes under or related to swap agreements. (c) Notwithstanding the preceding binding arbitration provisions, Bank and Borrower agree to preserve, without diminution, certain remedies that any party hereto may employ or exercise freely, independently or in connection with an arbitration proceeding or after an arbitration action is brought. Bank and Borrower shall have the right to proceed in any court of proper jurisdiction or by self-help or exercise or prosecute the following remedies, as applicable: (i) all rights to foreclose against any real or personal property or other security by exercising a power of sale granted under Loan Documents or under applicable law or by judicial foreclosure and sale, including a proceeding to confirm the sale; (ii) all rights of self-help including peaceful occupation of real property and collection of rents, set-off, and peaceful possession of personal property; (iii) obtaining provisional or ancillary remedies including injunctive relief, sequestration, garnishment, attachment, appointment of receiver and filing an involuntary bankruptcy proceeding; and (iv) when applicable, a judgment by confession of judgment. Preservation of these remedies does not limit the power of an arbitrator to grant similar remedies that may be requested by a party in a Dispute. Borrower and Bank agree that they shall not have a remedy of punitive or exemplary damages against the other in any Dispute and hereby waive any right or claim to punitive or exemplary damages they have now or which may arise in the future in connection with any Dispute whether the Dispute is resolved by arbitration or judicially. 12.4. Notices. Except as otherwise expressly provided herein, all notices hereunder shall be in writing and shall be delivered by telecopier, hand, overnight delivery or by mail. Notices given by mail shall be deemed to 23

Murphy, Jr. or in the case of either party, such other address as such party may, by written notice, received by the other party to this Agreement, have designated as its address for notices. Notices given by (i) telecopier shall be deemed to have been given when sent, (ii) hand shall be deemed to have been given the same day they have been sent and (iii) overnight delivery shall be deemed to have been given the day after they have been sent, in each case if properly addressed to the party to whom sent, at its address, as aforesaid. The Bank shall be entitled to reasonably rely upon any telephonic notices purportedly given pursuant to the terms of this Agreement and the Borrower shall hold the Bank harmless from any loss, cost or expense ensuing from any such reliance (other than that which results from the Bank's gross negligence or willful misconduct). 12.5. Appointment as Attorney-in-Fact. (a) Powers. The Borrower hereby irrevocably constitutes and appoints the Bank with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Borrower and in the name of the Borrower or in its own name, from time to time in the Bank's discretion, for the purpose of carrying out the terms of this Agreement and, upon the occurrence and during the continuance of any Event of Default to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement and the security interests granted herein, and without limiting the generality of the foregoing, the Borrower hereby gives the Bank the power and right (but not the obligation), on behalf of the Borrower, without notice to or assent by the Borrower, to do the following: (i) in the case of any Account, upon the occurrence and during the continuance of an Event of Default, or in the case of any other Collateral, at any time when any Event of Default shall have occurred and be continuing, in the name of the Borrower or its own name, or otherwise, to open mail addressed to the Borrower, to take possession of and endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Account, Instrument, General Intangible or contract right or with respect to any other Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Bank for the purpose of collecting any and all such moneys due under any such Account, Instrument, General Intangible or contract right or with respect to any other Collateral whenever payable; (ii) to pay or discharge taxes and liens levied or placed on or threatened against the Collateral, to effect any repairs or any insurance called for by the terms of this Security Agreement and to pay all or any part of the premiums therefor and the costs thereof; and (iii) upon the occurrence and during the continuance of any Event of Default, (A) to direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Bank or as the Bank shall direct; (B) to ask or demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (c) to sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any thereof and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against the Borrower with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described in clause (E) above and in connection therewith, to give such discharges or releases as the Bank may deem appropriate; and (G) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Bank was the absolute owner thereof for all purposes, and to do at the Bank's option and the Borrower's expense, at any time, or from time to time, all acts and things which the Bank deems necessary to protect, preserve or realize upon the Collateral and the liens granted hereunder and 24

1 Exhibit 10.1 $175,000,000 EMCORE CORPORATION 5% CONVERTIBLE SUBORDINATED NOTES DUE 2006 REGISTRATION RIGHTS AGREEMENT May 7, 2001 Credit Suisse First Boston Corporation Merrill Lynch, Pierce, Fenner & Smith Incorporated First Union Securities, Inc. c/o Credit Suisse First Boston Corporation Eleven Madison Avenue New York, New York 10010-3629 Dear Sirs: EMCORE Corporation, a New Jersey corporation (the "COMPANY"), proposes to issue and sell to Credit Suisse First Boston Corporation, Merrill Lynch, Pierce, Fenner & Smith Incorporated and First Union Securities, Inc. (collectively, the "INITIAL PURCHASERS"), upon the terms set forth in a purchase agreement of even date herewith (the "PURCHASE AGREEMENT"), $175,000,000 aggregate principal amount of its 5% Convertible Subordinated Notes due 2006 (the "NOTES"). The Notes will be convertible into shares of common stock of the Company (the "COMMON STOCK") at the conversion price set forth in the Offering Circular dated May 1, 2001. The Notes will be issued pursuant to an Indenture, dated as of May 7, 2001 (the "INDENTURE"), by and between the Company and Wilmington Trust Company, as trustee (the "Trustee"). As an inducement to the Initial Purchasers to enter into the Purchase Agreement, the Company agrees with the Initial Purchasers, (i) for the benefit of the Initial Purchasers and (ii) for the benefit of the holders of the Notes and the Common Stock issuable upon conversion or provisional redemption of the Notes (collectively, the "SECURITIES") from time to time until such time as such Securities have been sold pursuant to a Shelf Registration Statement (as defined below) (each of the foregoing a "HOLDER" and, together, the "HOLDERS"), as follows: 1. SHELF REGISTRATION. The Company shall take the following actions: (a) The Company shall promptly (but in no event more than 90 days after the first date of original issuance of the Notes (such 90th day being a "FILING DEADLINE")) file with the Commission and thereafter use its commercially reasonable efforts to cause to be declared effective no later than 180 days after the first date of original issuance of the Notes (such 180th day being an "EFFECTIVENESS DEADLINE") a registration statement (the "SHELF REGISTRATION STATEMENT") on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as defined herein) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the "SHELF REGISTRATION"); PROVIDED, HOWEVER, that

2 no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder. (b) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 2(h) below) from the date of its effectiveness or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) may be sold pursuant to Rule 144(k) under the Securities Act (or any successor rule therefore) (in any case, such period being called the "SHELF REGISTRATION PERIOD"). The Company shall be deemed not to have used its reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless such action is required by applicable law. (c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. (d) Each Holder of Transfer Restricted Securities agrees that if such Holder wishes to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related prospectus, it will do so only in accordance with this Section 1(d) and Section 2(b). Each Holder of Transfer Restricted Securities wishing to sell Transfer Restricted Securities pursuant to a Shelf Registration Statement and related prospectus agrees to deliver a written notice, substantially in the form of Annex A to the Offering Circular (a "NOTICE AND QUESTIONNAIRE") to the Company at least five (5) Business Days prior to any intended distribution of Transfer Restricted Securities under the Shelf Registration Statement (each such Holder delivering the Notice and Questionnaire, a "NOTICE HOLDER"). From and after the date the Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable after the date a Notice and Questionnaire is delivered (i) if required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any other document required under the Securities Act so that the Holder delivering such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related prospectus in such a manner as to permit such Holder to deliver such prospectus to purchasers of the Transfer Restricted Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date (the "Amendment Effectiveness Deadline Date") that is forty-five (45) days after the date such post-effective amendment is required by this clause to be filed; (ii) provide such Holder copies of any documents filed pursuant to Section 1(d)(i); and (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to Section 1(d)(i); provided that if such Notice and Questionnaire is delivered 2

3 during a Deferral Period, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 2(b). Notwithstanding anything contained herein to the contrary, (i) the Company shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in any Registration Statement or related prospectus and (ii) the Amendment Effectiveness Deadline Date shall be extended by up to ten (10) days from the expiration of a Deferral Period (and the Company shall incur no obligation to pay Additional Interest during such extension) if such Deferral Period is in effect on the Amendment Effectiveness Deadline Date; and provided further, that the Company shall not be obligated to file more than one (1) post-effective amendment or supplement in any twenty (20) day period following the date the Shelf Registration Statement is declared effective for the purpose of naming Holders as selling securityholders who were not named in the Shelf Registration Statement at the time of effectiveness. Any Holder who, subsequent to the date the Registration Statement is declared effective, provides a Notice and Questionnaire required by this Section 1(d) pursuant to the provisions of this Section (whether or not such Holder has supplied the Notice and Questionnaire at the time the Shelf Registration Statement was declared effective) shall be named as a selling securityholder in the Shelf Registration Statement and related prospectus in accordance with the requirements of this Section 1(d). 2. REGISTRATION PROCEDURES. In connection with any Shelf Registration contemplated by Section 1 hereof, the following provisions shall apply: (a) The Company shall (i) furnish to each Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Shelf Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Shelf Registration Statement, the Company shall use its reasonable efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose within a reasonable period of time; (ii) include the names of the Holders who propose to sell Securities pursuant to the Shelf Registration Statement, as selling shareholders. (b) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of a Shelf Registration Statement or the initiation of proceedings with respect to a Shelf Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a "Material Event") as a result of which any Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any prospectus shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (C) the occurrence or existence of any pending corporate development, public filing with the SEC or other similar event with respect to the Company that, in the reasonable discretion of the Company, makes it appropriate to suspend the availability of a Shelf Registration Statement and the related prospectus, (i) in the case of clause (B) above, subject to the next sentence, as promptly as practicable prepare and file, if necessary pursuant to applicable law, a post-effective amendment to such Registration Statement or a supplement to the related prospectus or any document incorporated therein by reference or file any other required document that would be incorporated by reference into such Registration Statement and prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and such prospectus does not contain 3

4 any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and, in the case of a post-effective amendment to a Registration Statement, subject to the next sentence, use reasonable efforts to cause it to be declared effective as promptly as is practicable, and (ii) give notice to the Notice Holders that the availability of the Shelf Registration Statement is suspended (a "Deferral Notice") and, upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Transfer Restricted Securities pursuant to the Registration Statement until such Notice Holder's receipt of copies of the supplemented or amended prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus. The Company will use reasonable efforts to ensure that the use of the prospectus may be resumed (x) in the case of clause (A) above, as promptly as is practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of the Company, such suspension is no longer appropriate. The Company shall be entitled to exercise its right under this Section 2(b) to suspend the availability of the Shelf Registration Statement or any prospectus, without incurring or accruing any obligation to pay Additional Interest pursuant to Section 6, for one or more periods not to exceed 90 consecutive days and not to exceed, in the aggregate, 120 days in any 12-month period (such period, during which the availability of the Registration Statement and any prospectus is suspended being a "Deferral Period"). (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Shelf Registration Statement. (d) The Company shall furnish to each Notice Holder included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment thereto (other than an amendment or supplement solely with respect to including the name of a Notice Holder in the Shelf Registration Statement, in which case, the Company shall furnish such amendment solely to such Notice Holder), including financial statements and schedules. (e) The Company shall, during the Shelf Registration Period, deliver to each Notice Holder included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each Notice Holder of the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. (f) Prior to any public offering of the Securities pursuant to the Shelf Registration Statement the Company shall register or qualify or cooperate with the Notice Holders and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or "blue sky" laws of such states of the United States as any Notice Holder reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by the Shelf Registration Statement; PROVIDED, HOWEVER, that the Company shall not be required to (i) qualify 4

5 generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. (g) The Company shall cooperate with the Notice Holders to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to the Shelf Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Notice Holders may request in writing a reasonable period of time prior to sales of the Securities pursuant to the Shelf Registration Statement. (h) If the Company notifies the Initial Purchasers and the Holders in accordance with Section 2(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers and the Holders shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 1(b) above shall be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers and the Holders shall have received such amended or supplemented prospectus pursuant to this Section 2(h). (i) Not later than the effective date of the Shelf Registration Statement, the Company will provide a CUSIP number for the Notes and the Common Stock registered under the Shelf Registration Statement, and provide the trustee with printed certificates for such Notes, in a form eligible for deposit with The Depository Trust Company. (j) The Company will comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company's first fiscal quarter commencing after the effective date of the Shelf Registration Statement, which statement shall cover such 12-month period; provided, that if the Company files the reports required by this Section 3(j) with the SEC and such reports are publicly available, it shall be deemed to have satisfied its obligation to furnish such reports to its securityholders pursuant to this Section 3(j). (k) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. (l) The Company may require each Holder that proposes to sell Securities pursuant to the Shelf Registration Statement to furnish to the Company a Notice and Questionnaire containing such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. (m) The Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder shall reasonably request in order to facilitate the disposition of the Securities pursuant to the Shelf Registration. 5

6 (n) Subject to the execution of a confidentiality agreement reasonably acceptable to the Company, the Company shall (i) make reasonably available for inspection by the Holders, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company's officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; PROVIDED, HOWEVER, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 3 hereof. (o) The Company, if requested by any Notice Holder covered by the Shelf Registration Statement, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Notice Holders and the managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date of the Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the Company and its subsidiaries; the qualification of the Company and its subsidiaries to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 2(m) hereof; the due authorization, execution, authentication and issuance, and the validity and enforceability, of the Securities; the absence, to such counsel's knowledge, of material legal or governmental proceedings involving the Company and its subsidiaries; the absence of governmental approvals required to be obtained in connection with the Shelf Registration Statement, the offering and sale of the Securities, or any agreement of the type referred to in Section 2(m) hereof; the compliance as to form of the Shelf Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and, as of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence from the Shelf Registration Statement and the prospectus included therein, as then amended or supplemented, and from any documents incorporated by reference therein of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof reasonably requested by any underwriters of the Securities and (iii) its independent public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the Notice Holders and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72. (p) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the Securities covered by the Shelf Registration Statement contemplated hereby. 6

7 3. REGISTRATION EXPENSES. (a) Subject to Section 8 hereof, all expenses incident to the Company's performance of and compliance with this Agreement will be borne by the Company, regardless of whether the Shelf Registration Statement is ever filed or becomes effective, including without limitation; (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state "blue sky" or securities laws; (iii) all expenses of printing (including printing of prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company; (v) all application and filing fees in connection with listing the Securities on a national securities exchange or automated quotation system pursuant to the requirements hereof; and (vi) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance). The Company will bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any person, including special experts, retained by the Company. (b) In connection with the Shelf Registration Statement required by this Agreement, the Company will reimburse the Initial Purchasers and the Notice Holders of Transfer Restricted Securities who are selling or reselling Securities pursuant to the "Plan of Distribution" contained in the Shelf Registration Statement for the reasonable fees and disbursements of not more than one counsel, who shall be Latham & Watkins unless another firm shall be chosen by the Notice Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such Shelf Registration Statement is being prepared. 4. INDEMNIFICATION. (a) The Company agrees to indemnify and hold harmless each Notice Holder and each person, if any, who controls such Notice Holder within the meaning of the Securities Act or the Exchange Act (each Notice Holder and such controlling persons are referred to collectively as the "INDEMNIFIED PARTIES") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; PROVIDED, HOWEVER, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration in reliance upon and in conformity with written information pertaining to such Notice Holder and furnished to the Company by or on behalf of such Notice 7

8 Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to the Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Notice Holder from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered by such Notice Holder under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Notice Holder results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final prospectus if the Company had previously furnished copies thereof to such Notice Holder; PROVIDED FURTHER, HOWEVER, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Notice Holders of the Securities if requested by such Notice Holders. (b) Each Notice Holder, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Notice Holder and furnished to the Company by or on behalf of such Notice Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Notice Holder may otherwise have to the Company or any of its controlling persons. (c) Promptly after receipt by an indemnified party under this Section 4 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 4, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 4 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims 8

9 that are the subject matter of such action, and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) If the indemnification provided for in this Section 4 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the exchange of the Securities, pursuant to the Shelf Registration, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Notice Holder or such other indemnified party, as the case may be, on the other, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 4(d), the Notice Holders shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Notice Holders from the sale of the Securities pursuant to the Shelf Registration Statement exceeds the amount of damages which such Notice Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. (e) The agreements contained in this Section 4 shall survive the sale of the Securities pursuant to the Shelf Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 5. HOLDERS OBLIGATIONS. Each Holder agrees, by acquisition of the Transfer Restricted Securities, that no Holder of Transfer Restricted Securities shall be entitled to sell any of such Transfer Restricted Securities pursuant to a Registration Statement or to receive a prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 1(d) hereof and the information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Notice Holder not misleading and any other information regarding such Notice Holder and the distribution of such Transfer Restricted Securities as the Company may from time to time reasonably request. Any sale of any Transfer Restricted Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its plan of distribution is as set forth in the prospectus delivered by such Holder in connection with such disposition, that such prospectus does not as of 9

10 the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan of distribution and that such prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such prospectus, in the light of the circumstances under which they were made, not misleading. Each Holder agrees that within ten (10) business days of any sale, disposition or other transfer of Securities, whether pursuant to a Registration Statement or exemption from registration under the Securities Act, such Holder shall provide written notice to the Company specifying the amount of Securities sold, disposed of or transferred and the name and address of the transferree of such Securities. 6. ADDITIONAL INTEREST UNDER CERTAIN CIRCUMSTANCES. (a) Additional interest (the "ADDITIONAL INTEREST") with respect to the Notes shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a "REGISTRATION DEFAULT"): (i) the Shelf Registration Statement required by this Agreement is not filed with the Commission on or prior to the Filing Deadline; (ii) the Shelf Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline; (iii) the Company fails with respect to a Holder that supplies a Notice and Questionnaire to supplement the Shelf Registration Statement in a timely manner in order to name additional selling shareholders; or (iv) the Shelf Registration Statement required by this Agreement has been declared effective by the Commission but (A) the Shelf Registration Statement thereafter ceases to be effective or (B) the Shelf Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified herein (other than pursuant to Section 1(c) hereof) and (1) the Company fails to cure the Registration Default within five business days by a post-effective amendment or a report filed pursuant to the Exchange Act or (2) if applicable, the Company does not terminate the Deferral Period by the 90th day, as the case may be. Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission. Additional Interest shall accrue daily on the Notes over and above the interest set forth in the title of the Notes from and including the date on which any such Registration Default shall occur to, but excluding, the date on which all such Registration Defaults have been cured, at a rate of 0.50% per annum for the notes (the "ADDITIONAL INTEREST RATE") and, if applicable, on an equivalent basis per share (subject to adjustment in the case of stock splits, stock recombinations, stock dividends and the like) of Common Stock issuable upon conversion of the Notes. (b) A Registration Default referred to in Section 6(a)(iv) hereof shall be deemed not to have occurred and be continuing in relation to the Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to the Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Notice Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in the Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement the Shelf Registration Statement and related prospectus to describe such events; PROVIDED, 10

11 HOWEVER, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. (c) Any amounts of Additional Interest due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the Notes. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest Rate by the principal amount of the Notes and further multiplied by a fraction, the numerator of which is the number of days such Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. (d) "TRANSFER RESTRICTED SECURITIES" means each Security until (i) the date on which such Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (ii) the date on which such Security is distributed to the public pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act. 7. RULES 144 AND 144A. The Company shall use its best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Securities identified to the Company by the Initial Purchasers upon request. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 8. UNDERWRITTEN REGISTRATIONS. If any of the Transfer Restricted Securities covered by the Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering ("MANAGING UNDERWRITERS") will be selected by the Notice Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering (provided that the Holders of Common Stock issued upon conversion of Notes shall not be deemed Holders of Common Stock, but shall be deemed to be Holders of the aggregate principal amount of Notes from which such Common Stock was converted). No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person's Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. Notwithstanding any other provisions of this Agreement to the contrary, the Company shall not be required to pay the expenses of an underwritten offering of Transfer Restricted Securities pursuant to this Section 8 unless such underwritten offering is for Transfer Restricted Securities in the aggregate principal amount of at least $50,000,000 and shall not be required to pay any underwriter discount, commission or similar fees related to the sale of the Transfer Restricted Securities. 11

12 9. MISCELLANEOUS. (a) REMEDIES. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 1 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Sections 1 hereof. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. (b) NO INCONSISTENT AGREEMENTS. The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof. (c) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Transfer Restricted Securities (provided that the Holders of Common Stock issued upon conversion of Notes shall not be deemed Holders of Common Stock, but shall be deemed to be Holders of the aggregate principal amount of Notes from which such Common Stock was converted) affected by such amendment, modification, supplement, waiver or consents. (d) NOTICES. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery: (1) if to a Holder, that is not a Notice Holder, at the most current address given by such Holder to the Company.

(k) SECURITIES HELD BY THE COMPANY. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 13
