The Company also proposes to issue and sell at the option of the Initial Purchasers an additional $20,000,000 aggregate principal amount of its 3¼% Contingent Convertible Subordinated Notes Due 2025 (the “Option Securities” and together with the Firm Securities, the “Securities”) as set forth in Schedule I hereto and in accordance with terms set forth below. The Securities will be issued pursuant to an indenture (the “Indenture”), to be dated as of the Closing Date (as defined in Section 2 hereof), between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”).

The Securities will be convertible into shares of common stock of the Company, $0.0001 par value (“Common Stock”). The shares of Common Stock into which the Securities may be convertible are referred to herein as the “Underlying Securities.”

The sale of the Securities and the Underlying Securities will be made without registration under the Securities Act of 1933, as amended (the “Securities

Act”), in reliance on exemptions from the registration requirements of the Securities Act. The Initial Purchasers have advised the Company that the Initial Purchasers will offer and sell the Securities purchased by them hereunder (the “Offering”) in accordance with Section 3 hereof as soon as they deem advisable.

In connection with the Offering, the Company has prepared a preliminary Offering Memorandum dated May 31, 2005 (including the information incorporated by reference therein, the “Preliminary Offering Memorandum”) and a final Offering Memorandum, dated June 2, 2005 (including the information incorporated by reference therein, the “Offering Memorandum”). Each of the Preliminary Offering Memorandum and the Offering Memorandum sets forth or incorporates by reference certain information regarding the Company, the Securities and the Underlying Securities. The Company hereby confirms that it has authorized the use of the Preliminary Offering Memorandum and the Offering Memorandum, and any amendment or supplement thereto, in connection with the Offering. Unless stated to the contrary, all references herein to the Offering Memorandum are to the Offering Memorandum at the date thereof and are not meant to include any amendment or supplement, or any information incorporated by reference therein subsequent to the date thereof and any references herein to the terms “amend,” “amendment” or “supplement” with respect to the Offering Memorandum shall be deemed to refer to and include any information filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), subsequent to the date of the Offering Memorandum which is incorporated by reference therein.

In connection with the Offering, the Company also proposes to enter into a Registration Rights Agreement, to be dated as of the Closing Date, between the Company and the Initial Purchasers (the “Registration Rights Agreement”).

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

Delivery of and payment for the Firm Securities shall be made at the offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill Road, Palo Alto, California 94304 at 9:30 A.M., New York City time, on the fourth full business day following the date of this Agreement, or at such other place, time or date not later than five business days thereafter as the Initial Purchasers and the Company may agree upon.

The Initial Purchasers may from time to time thereafter change the price and other selling terms.

Accordingly, each Initial Purchaser agrees that it will offer and sell the Securities only to persons that it reasonably believes to be qualified institutional buyers as defined in Rule 144A under the Securities Act.

(c) Each Initial Purchaser agrees that neither it nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (as those terms are used in Rule 502(c) of Regulation D under the Securities Act) in connection with any offer or sale of the Securities in the United States.

The Company covenants and agrees with the Initial Purchasers that:

(a) The Company will furnish to the Initial Purchasers and counsel for the Initial Purchasers, without charge, during the period mentioned in paragraph (d) below, as many copies of the Preliminary Offering Memorandum and Offering Memorandum, any documents incorporated by reference therein and any supplements or amendments thereto as they may reasonably request.

(d) If at any time prior to the date on which all of the Securities shall have been sold by the Initial Purchasers, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Initial Purchasers, it becomes necessary to amend or supplement the Offering Memorandum in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Offering Memorandum to comply with applicable law, the Company promptly will prepare an appropriate amendment or supplement to the Offering Memorandum so that the Offering Memorandum as so amended or supplemented will not contain statements that, in the light of the circumstances under which they were made, are misleading, or so that the Offering Memorandum will comply with applicable law.

The foregoing sentences shall not apply to (A) the sale of the Securities under this Agreement, (B) the issuance by the Company of the Underlying Securities pursuant to the terms of the Indenture, (C) the issuance by the Company of shares of Common Stock, stock appreciation rights or common stock equivalents or warrants, rights or options to purchase any of the following, pursuant to any employee, officer or director stock option plan or other benefit plan in effect on the date hereof and described in the Company’s Exchange Act filings (D) the issuance by the Company of any shares of Common Stock upon the exercise of an option, warrant or management subscription right, or the conversion of a security, in each case, outstanding on the date hereof and described in the Company’s Exchange Act filings or (E) the filing of shelf registration statements in respect of the Securities and the Underlying Shares pursuant to the terms of the Registration Rights Agreement or any registration statement in respect of any employee, officer or director stock option or other benefit plan.

(g) Except as contemplated by Section 4(e) or the Registration Rights Agreement, neither the Company, nor any of its Affiliates, nor any person acting on its behalf will, directly or indirectly, make offers or sales of any security, or solicit offers to buy any security, under circumstances that would require the registration of the Securities or the Underlying Securities under the Securities Act.

(h) The Company shall not, and shall use its reasonable best efforts to cause its Affiliates not to, engage in any form of general solicitation or general advertising (as those terms are used in Rule 502(c) of Regulation D under the Securities Act) in connection with any offer or sale of the Securities in the United States.

(i) So long as any of the Securities or the Underlying Securities are “restricted securities” within the meaning of Rule

144(a)(3) under the Securities Act, the Company will, during any period in which it is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act or exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted securities.

(l) The Company shall apply the net proceeds of its sale of the Securities as set forth in the Offering Memorandum.

(m) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Securities in such a manner as would require the Company to register as an “investment company” under the Investment Company Act.

(n) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(o) For so long as any Securities remain outstanding, the Company will furnish to the Initial Purchasers copies of all reports and other communications (financial or otherwise) furnished by the Company to the Trustee or the holders of the Securities.

5. COSTS AND EXPENSES.

The Company will pay all costs, expenses and fees incident to the performance of its obligations under this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Company; the fees and disbursements of counsel for the Company; the cost of printing and delivering to, or as reasonably requested by, the Initial Purchasers copies of the Preliminary Offering Memorandum and the Offering Memorandum and any supplements or amendments thereto and the printing and production of all other documents connected with the transactions contemplated herein (including this Agreement, the Indenture, the Registration Rights Agreement and any other related agreements); the listing fee of the Nasdaq National Market; the expenses arising from having the Securities designated as eligible in the PORTAL market; the expenses associated with the preparation, issuance and delivery to the Initial Purchasers of the Securities; the fees and expenses of the Trustee, including fees and expenses of its counsel; the expenses of the “roadshow” and any other meetings with prospective investors in the Securities; the costs and expenses of advertising relating to the Offering (other than advertising costs and expenses that the Initial Purchasers expressly agree to pay); and the expenses, including the fees and disbursements of counsel for the Initial Purchasers, incurred in connection with the qualification of the Securities under state securities or “Blue Sky” laws; and any fees charged by investment rating agencies for the rating of the Securities. The Company shall not, however, be required to pay for any of the Initial Purchasers’ expenses (other than those related to qualification under state securities or “Blue Sky” laws) except that, if this Agreement shall not be consummated because the conditions in Section 6 hereof are not satisfied, or because this Agreement is terminated by the Initial Purchasers pursuant to Section 9 hereof, or by reason of any failure, refusal or inability on the part of the Company to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on their part to be performed, unless such failure, refusal or inability is due to the default or omission of the Initial Purchasers, the Company shall reimburse the Initial Purchasers for reasonable out-of-pocket expenses, including fees and disbursements of Wilson Sonsini Goodrich & Rosati, counsel for the Initial Purchasers, reasonably incurred in connection with investigating, marketing and proposing to market the Securities or in contemplation of performing their obligations hereunder; but the Company shall not in any event be liable to the Initial Purchasers for damages on account of loss of anticipated profits from the sale by the Initial Purchasers of the Securities.

6. CONDITIONS OF OBLIGATIONS OF THE INITIAL PURCHASERS.

The obligation of the Initial Purchasers to purchase the Firm Securities on the Closing Date and the Option Securities, if any, on the Option Closing Date are subject to the accuracy, as of the Closing Date or the Option Closing Date, as the

case may be, of the representations and warranties of the Company contained herein, and to the performance by the Company of its covenants and obligations hereunder and to the following additional conditions:

(a) The Initial Purchasers shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion of Latham & Watkins, counsel for the Company, dated the Closing Date or the Option Closing Date, as the case may be, addressed to the Initial Purchasers to the effect that:

1. The Company is a corporation under the DGCL, with corporate power and authority to own its properties and to conduct its business as described in the Offering Memorandum. Based on certificates from public officials, such counsel shall confirm that the Company is validly existing and in good standing under the laws of the State of Delaware and is qualified to do business in the States of Alabama, California, Colorado, Florida, Georgia, Massachusetts, New Jersey, New York, North Carolina, Pennsylvania and Texas.

2. This Agreement has been duly authorized by all necessary corporate action on the part of the Company, and this Agreement has been duly executed and delivered by the Company.

3. The Indenture has been duly authorized by all necessary corporate action of the Company, and the Indenture has been duly executed and delivered by the Company and is the legally valid and binding agreement of the Company, enforceable against the Company in accordance with its terms.

4. The Firm Securities have been duly authorized by all necessary corporate action of the Company and the Firm Securities have been duly executed and delivered by the Company, and when authenticated by the Trustee in accordance with the terms of the Indenture and delivered to and paid for by you in accordance with the terms of this Agreement, will be the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

5. The Underlying Securities have been duly authorized and reserved by all necessary corporate action of the Company and the Underlying Securities, if any, issued upon due conversion of the Firm Securities in accordance with the terms of the Firm Securities and the Indenture would, if issued today, be validly issued, fully paid and nonassessable and free of

preemptive rights arising under the Company’s certificate of incorporation, bylaws or the DGCL.

6. The Registration Rights Agreement has been duly authorized by all necessary corporate action of the Company, and the Registration Rights Agreement has been duly executed and delivered by the Company and is the legally valid and binding agreement of the Company, enforceable against the Company in accordance with its terms.

7. The execution and delivery of the Purchase Agreement, the Indenture, the Firm Securities and the Registration Rights Agreement by the Company, the issuance and sale of the Firm Securities by the Company pursuant to this Agreement and the consummation by the Company of the transactions contemplated by this Agreement, the Indenture and the Firm Securities on the date hereof do not:

(i) violate, conflict with or constitute a default under the Company’s certificate of incorporation or bylaws;

(ii) violate or conflict with the DGCL or any federal, California or New York statute, rule or regulation applicable to the Company; or

(iii) violate or conflict with any court or governmental orders, writs, judgments or decrees specifically directed to the Company that were identified to such counsel by an officer of the Company and listed in Exhibit A (the “Court Orders”); or

(iv) violate, conflict with or result in the breach of or any default under any indentures, notes, loan agreements, mortgages, deeds of trust, security agreements and other written agreements and instruments of the Company that are listed as exhibits to the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2004 or the Company’s Quarterly Reports on Form 10-Q for the fiscal quarters ended September 30, 2004, December 31, 2004 or March 31, 2004 (collectively, the “Material Agreements”); or

(v) require any consents, approvals or authorizations to be obtained by the Company, or any registrations, declarations or filings to be made by the Company, in each case, under the DGCL or any federal, California or New York statute, rule or regulation applicable to the Company,

except such as may be required under state securities laws in connection with the purchase and distribution of the Firm Securities by the Initial Purchasers.

8. Assuming that the representations, warranties and agreements of the Initial Purchasers contained in the Purchase Agreement are accurate and have been complied with, no registration of the Firm Securities under the Securities Act of 1933, as amended (the “Securities Act”), and no qualification of the Indenture under the Trust Indenture Act of 1939, as amended, is required for the purchase of the Firm Securities by the Initial Purchasers or the initial resale of the Firm Securities by the Initial Purchasers to “qualified institutional buyers” (as such term is defined under Rule 144A under the Securities Act), in the manner contemplated by this Agreement and the Offering Memorandum. Such counsel need not express an opinion, however, as to when or under what circumstances any Firm Securities initially sold by the Initial Purchasers may be reoffered or resold.

9. The statements in the Offering Memorandum under the captions “Description of Notes” and “Description of Capital Stock,” insofar as they purport to describe or summarize certain provisions of the instruments or constitute a summary of the legal matters or documents referred to therein, are accurate descriptions or summaries in all material respects.

10. The statements in the Offering Memorandum under the caption “Certain United States Federal Income Tax Consequences,” insofar as they purport to summarize certain provisions of the statutes and regulations referred to therein, are accurate summaries in all material respects.

11. With the Initial Purchasers’ consent based solely on a certificate of an officer of the Company as to factual matters, the Company is not, and after giving effect to the sale of the Firm Securities as contemplated in this Agreement and the application of the proceeds as described in the Offering Memorandum under the caption “Use of Proceeds,” will not be required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

12. To such counsel’s knowledge, the Company is not subject to any pending litigation that seeks to restrain or enjoin the Offering or that seeks monetary damages in excess of $1,000,000, other than as set forth in the Offering Memorandum.

The primary purpose of such counsel’s professional engagement was not to establish or confirm factual matters or financial or quantitative information. Therefore, such counsel need not pass upon and need not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Offering Memorandum(1) (except to the extent expressly set forth in the numbered paragraph 10 of such counsel’s opinion letter to the Initial Purchasers of even date thereof), and have not made an independent check or verification thereof (except as aforesaid). However, such counsel will state that in the course of acting as counsel to the Company in connection with the preparation by the Company of the Offering Memorandum, such counsel has reviewed the Offering Memorandum, and participated in conferences and telephone conversations with officers and other representatives of the Company, the independent public accountants for the Company, the Initial Purchasers’ representatives, and the Initial Purchasers’ counsel, during which conferences and conversations the contents of the Offering Memorandum and related matters were discussed. Such counsel may also that state that it has reviewed and relied upon certain corporate records and documents and oral and written statements of officers and other representatives of the Company and others as to the existence and consequence of certain factual and other matters.

In addition to the matters set forth above, such opinion shall also include a statement to the effect that, based on such counsel’s participation, review and reliance as described above, no facts came to its attention that caused it to believe that the Offering Memorandum, as of its date or as of the Closing Date or the Option Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; it being understood that such counsel need not express a belief with respect to the financial statements, schedules, or other financial data included or incorporated by reference in, or omitted from, the Offering Memorandum.

The opinion of such counsel described in this Section shall be rendered to the Initial Purchasers at the request of the Company and shall so state therein.

References to the Offering Memorandum in this subsection (a) shall include any amendment or supplement thereto prepared in accordance with the provisions of this Agreement at the Closing Date or the Option Closing Date, as the case may be.

In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than the Federal laws of the United

(1) To include documents incorporated by referenced into the Offering Memorandum, but excluding financial statements, schedules or other financial data included or incorporated by reference in, or omitted from, the Offering Memorandum.

States and the laws of the States of New York, Delaware and California. Such counsel may also state that, insofar as such opinion involves factual matters, such counsel have relied, to the extent they deem proper, upon certificates of officers of the Company and certificates of public officials; provided that such certificates have been provided to the Initial Purchasers.

(b) The Initial Purchasers shall have received an opinion, dated the Closing Date or the Option Closing Date, as the case may be, of Wilson Sonsini Goodrich & Rosati, counsel for the Initial Purchasers, with respect to certain legal matters relating to this Agreement, and such other related matters as the Initial Purchasers may reasonably require. In rendering such opinion, Wilson Sonsini Goodrich & Rosati shall have received and may rely upon such certificates and other documents and information as they may reasonably request to pass upon such matters.

(c) The Initial Purchasers shall have received, on each of the date hereof, the Closing Date and, if applicable, the Option Closing Date, letters dated the date hereof, the Closing Date or the Option Closing Date, as the case may be, in form and substance satisfactory to the Initial Purchasers and counsel for the Initial Purchasers, of Deloitte & Touche LLP confirming that they are independent public accountants within the meaning of the Securities Act and the applicable published rules and regulations thereunder and stating that in their opinion the financial statements and schedules of the Company examined by them and incorporated by reference in the Offering Memorandum comply in form in all material respects with the applicable accounting requirements of the Securities Act and the Exchange Act and the respective related published rules and regulations; and containing such other statements and information as is ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial and statistical information contained or incorporated by reference in the Offering Memorandum.

(d) The Initial Purchasers shall have received on the Closing Date and, if applicable, the Option Closing Date, as the case may be, a certificate or certificates of the Chief Executive Officer and the Chief Financial Officer of the Company to the effect that, as of the Closing Date or the Option Closing Date, as the case may be, each of them severally represents as follows:

(i) the representations and warranties of the Company contained in Section 1 hereof are true and correct as of the Closing Date or the Option Closing Date, as the case may be;

(ii) he or she has carefully examined the Offering Memorandum (including the documents of the Company

incorporated by reference therein) and, in his or her opinion, as of the Closing Date or Option Closing Date as the case may be, the statements contained in the Offering Memorandum (including the documents of the Company incorporated by reference therein) with respect to the Company are true and correct, and with respect to the Company such Offering Memorandum (including the documents of the Company incorporated by reference therein) does not omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(iii) since the respective dates as of which information is given in the Offering Memorandum, there has not been any Material Adverse Change or any development involving a prospective Material Adverse Change, whether or not arising in the ordinary course of business; and

(iv) the Company has performed all covenants and agreements and satisfied all conditions on its part to be performed or satisfied at or prior to the Closing Date or the Option Closing Date, as the case may be.

(e) The Company shall have furnished to the Initial Purchasers such further certificates and documents confirming the representations and warranties, covenants and conditions contained herein and related matters as the Initial Purchasers may reasonably have requested.

(f) The Securities shall have been designated as PORTAL-eligible securities.

(g) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the Company’s securities or the rating of any Subsidiary by any “nationally recognized statistical rating organization”, as such term is defined for purposes of Rule 436(g)(2) under the Securities Act.

(h) Each of the Indenture and the Registration Rights Agreement shall have been executed and delivered by all the parties thereto.

(i) The Company shall have caused each executive officer and director of the Company to furnish to Deutsche Bank Securities Inc., on or prior to the date of this agreement, a letter or letters, in substantially the form attached hereto as Exhibit A, and such letter or letters shall be in full force and effect.

The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Initial Purchasers.

7. INDEMNIFICATION.

(a) The Company agrees:

(i) to indemnify and hold harmless the Initial Purchasers and the affiliates, directors, officers, agents, representatives and employees of each Initial Purchaser and each person, if any, who controls each Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which any Initial Purchaser or any such affiliate, director, officer, agent, representative, employee or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (x) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Offering Memorandum or any amendment or supplement thereto, (y) the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (z) any act or failure to act, or any alleged act or failure to act by the Initial Purchasers in connection with, or relating in any manner to, the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (x) or (y) above (provided that the Company shall not be liable under this clause (z) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by the Initial Purchasers through its gross negligence or willful misconduct); provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or

alleged omission made in any Preliminary Offering Memorandum, the Offering Memorandum, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser specifically for use in the preparation thereof; and

(ii) to reimburse each Initial Purchaser and each such affiliate, director, officer, agent, representative and employee and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Initial Purchaser, such affiliate, director, officer, agent, representative or employee or such controlling person in connection with investigating or defending or appearing as a third-party witness in connection with any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the Offering, whether or not such Initial Purchaser or any such controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that such Initial Purchaser was not entitled to receive payments for legal and other expenses pursuant to this subparagraph, such Initial Purchaser will promptly return all sums that had been advanced pursuant hereto.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its affiliates, directors, officers, agents, representatives and employees and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or any such affiliate, director, officer, agent, representative, employee or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Offering Memorandum or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and will reimburse any legal or other expenses reasonably incurred by the Company or any such affiliate, director, officer, agent, representative, employee or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Initial Purchaser will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in any Preliminary

Offering Memorandum, the Offering Memorandum or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser specifically for use in the preparation thereof. This indemnity agreement will be in addition to any liability which the Initial Purchasers may otherwise have.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 7, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 7(a) or (b) shall be available to any party who shall fail to give notice as provided in this Section 7(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 7(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense of and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by

Deutsche Bank Securities Inc. in the case of parties indemnified pursuant to Section 7(a) and by the Company in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) 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. If settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(d) To the extent the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchasers. The relative fault 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 the Initial Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 7(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), (i) the Initial Purchasers shall not be required to contribute any amount in excess of the discounts and commissions applicable to the Securities purchased by the Initial Purchasers and (ii) 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.

(e) In any proceeding relating to any Preliminary Offering Memorandum, the Offering Memorandum or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 7 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party.

(f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of the Initial Purchasers or any affiliate, director, officer, agent, representative or employee of any Initial Purchaser or any person controlling the Initial Purchasers, the Company, any director or officer of the Company or any person controlling the Company, (ii) acceptance

of any Securities and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Initial Purchaser or any affiliate, director, officer, agent, representative or employee of the Initial Purchasers or any person controlling any Initial Purchaser, or to the Company, any director or officer of the Company or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7.

8. NOTICES.

All communications hereunder shall be in writing and, except as otherwise provided herein, shall be mailed, delivered, telecopied, faxed or telegraphed and confirmed as follows: if to the Initial Purchasers, to Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10005; Attention: Equity Capital Markets, Fax: (212) 797-9344, with a copy to Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10019, Attention: General Counsel, Fax: (212) 797-4564; if to the Company, to 2300 Orchard Parkway, San Jose, California Attention: Chief Financial Officer, Fax: (408) 428-7894; with a copy to Latham & Watkins LLP, 135 Commonwealth Drive, Menlo Park, California 94025, Attention: Ora T. Fisher, Esq., Fax: (650) 463-2600.

9. TERMINATION.

(a) This Agreement may be terminated by the Initial Purchasers by notice to the Company at any time prior to the Closing Date or the Option Closing Date (if different from the Closing Date and then only as to Option Securities) if any of the following has occurred: (i) since the date as of which information is given in the Offering Memorandum, any Material Adverse Change or any development involving a prospective Material Adverse Change, whether or not arising in the ordinary course of business, (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States would, in the sole judgment of the Initial Purchasers, make it impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, (iii) suspension of trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on any such exchange or market, (iv) the enactment, publication, decree or other promulgation of any statute, regulation, rule or order of any court or other governmental

authority which in the opinion of the Initial Purchasers materially and adversely affects or may materially and adversely affect the business or operations of the Company, (v) the declaration of a banking moratorium by United States or New York State authorities, (vi) any downgrading, or placement on any watch list for possible downgrading, in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Exchange Act), (vii) the suspension of trading of the Company’s common stock by the New York Stock Exchange, the Commission, or any other governmental authority, or (viii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States; or

(b) If any of the conditions hereinabove provided for in Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, the Initial Purchasers may terminate their obligations hereunder by notifying the Company of such termination in writing or by telegram at or prior to the Closing Date or the Option Closing Date, as the case may be.

In such event, the Company and the Initial Purchasers shall not be under any obligation to each other (except to the extent provided in Sections 5 and 7 hereof).

10. DEFAULTING INITIAL PURCHASERS.

(a) If, on a Closing Date, any Initial Purchaser shall fail or refuse to purchase the Firm Securities that they are obligated to purchase pursuant to this Agreement (the “Defaulted Securities”), and arrangements satisfactory to the Company for the purchase of the Firm Securities are not made within 36 hours after such default, then (i) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such Closing Date, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective obligations hereunder bear to the obligations of all non-defaulting Initial Purchasers, or (ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on such Closing Date, this Agreement shall terminate without liability on the part of the Company, except to the extent provided in Sections 5, 7 and 13. If arrangements satisfactory to the Company for the purchase of the Firm Securities are made within 36 hours after such default, the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days,

in order that the required changes, if any, in the Offering Memorandum or in any other documents or arrangements may be effected. Any action taken under this Section 10 shall not relieve any defaulting Initial Purchasers from liability in respect of any default of such Initial Purchasers under this Agreement.

11. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Initial Purchasers and the Company and their respective successors and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Securities from the Initial Purchasers shall be deemed a successor or assign merely because of such purchase.

12. INFORMATION PROVIDED BY THE INITIAL PURCHASERS.

The Company and the Initial Purchasers acknowledge and agree that the only information furnished or to be furnished by the Initial Purchasers to the Company for inclusion in the Offering Memorandum consists of the following information set forth under the section entitled “Plan of Distribution” (i) the table following the first paragraph, (ii) the first sentence of the third paragraph (references to paragraphs exclude the table), (iii) the third sentence of the fourth paragraph, (iv) the seventh paragraph, including the bullet points and (v) the third sentence of the eighth paragraph, in each case insofar as such information relates to the Initial Purchasers.

13. MISCELLANEOUS.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of the Initial Purchasers or any affiliate, director, officer, agent, representative or employee of any Initial Purchaser or any person controlling the Initial Purchasers, the Company, any director or officer of the Company or any person controlling the Company and (c) acceptance of any Securities and payment therefore hereunder.

This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Ladies & Gentlemen:

The undersigned understands that Deutsche Bank Securities Inc. and RBC Capital Markets (the “Initial Purchasers”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) with Symmetricom, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) by the Initial Purchasers of securities convertible into shares of common stock, par value $0.0001, of the Company (the “Common Stock”).

To induce the Initial Purchasers to continue their efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of Deutsche Bank Securities Inc., it will not directly or indirectly offer, sell, pledge, contract to sell (including any short sale), grant any option to purchase or otherwise dispose of any shares of Common Stock (including, without limitation, shares of Common Stock of the Company which may be deemed to be beneficially owned by the undersigned on the date hereof in accordance with the rules and regulations of the Securities and Exchange Commission, shares of Common Stock which may be issued upon exercise of a stock option or warrant and any other security convertible into or exchangeable for Common Stock) or enter into any Hedging Transaction (as defined below) relating to the Common Stock (each of the foregoing referred to as a “Disposition”) for a period from the date hereof until and including the date that is 90 days after the date of the final offering memorandum relating to the Offering (the “Lock-Up Period”). The foregoing restriction is expressly intended to preclude the undersigned from engaging in any Hedging Transaction or other transaction which is designed to or reasonably expected to lead to or result in a Disposition during the Lock-Up Period even if the securities would be disposed of by someone other than the undersigned. “Hedging Transaction” means any short sale (whether or not against the box) or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from the Common Stock.

Notwithstanding the foregoing, the undersigned may transfer (a) shares of Common Stock acquired in open market transactions by the undersigned after the date of the Offering Memorandum, (b) a sufficient number of shares of Common Stock to cover any tax liabilities incurred in conjunction with the vesting of those shares of Common Stock, if any, listed opposite the undersigned’s name on Schedule 1 attached hereto, such number of shares not to exceed the number listed opposite the undersigned’s name on Schedule 1, and (c) any or all of the shares of Common Stock or other Company securities if the transfer is by (i) gift, will or intestacy, or (ii) distribution to partners, members or shareholders of the undersigned; provided that in the case of a transfer pursuant to clause (c) above, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding the securities subject to the provisions of this letter agreement.

The undersigned agrees that the Company may, and that the undersigned will, (i) with respect to any shares of Common Stock or other Company securities for which the undersigned is the record holder, cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company and (ii) with respect to any shares of Common Stock or other Company securities for which the undersigned is the beneficial holder but not the record holder, cause the record holder of such securities to cause the transfer agent for the Company to note stop transfer instructions with respect to such securities on the transfer books and records of the Company.

In addition, the undersigned hereby waives any and all notice requirements and rights with respect to registration of securities pursuant to any agreement, understanding or otherwise setting forth the terms of any security of the Company held by the undersigned, including any registration rights agreement to which the undersigned and the Company may be party, provided that such waiver shall apply only to the proposed Offering, and any other action taken by the Company in connection with the proposed Offering.

The undersigned hereby agrees that, to the extent that the terms of this letter agreement conflict with or are in any way inconsistent with any registration rights agreement to which the undersigned and the Company may be a party, this letter agreement supersedes such registration rights agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement. All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.
