          (c) InterSAN Warrants. At the Effective Time, all then outstanding warrants to purchase InterSAN Capital Stock (each, an “InterSAN Warrant”) which are not exercised or do not otherwise expire as of the Effective Time shall be assumed by Finisar and converted into a warrant (an “Assumed Warrant”) to acquire, on the same terms and conditions as were applicable under the InterSAN Warrant, such number of shares of Finisar Common Stock which the holder of such InterSAN Warrant would have been entitled to receive pursuant to the Merger pursuant to Section 2.2(b) if the InterSAN Warrant had been exercised prior to the Effective Time (rounded down to the nearest whole share) at a price per share (rounded up to the nearest whole cent) equal to (i) the aggregate exercise price of the InterSAN Capital Stock purchasable pursuant to such InterSAN Warrant immediately prior to the Effective Time divided by (ii) the number of full shares of Finisar Common Stock purchasable pursuant to the Assumed Warrant.

     Section 2.3 Exchange of Certificates. The procedures for exchanging outstanding shares of InterSAN Capital Stock for Finisar Common Stock and cash pursuant to the Merger are as follows:

          (a) Exchange Agent. Promptly after the Effective Time, Finisar shall cause to be deposited with an exchange agent designated by Finisar (the “Exchange Agent”), for exchange in accordance with this Section 2.3, through the Exchange Agent, shares of Finisar Common Stock issuable and payable to the holders of InterSAN Capital Stock pursuant to Section 2.2, less the Escrow Shares issuable and deliverable to the Escrow Agent pursuant to Section 2.4 (such shares of Finisar Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”), in exchange for outstanding shares of InterSAN Capital Stock.

          (b) Exchange Procedures. Upon surrender by a holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of InterSAN Capital Stock (each a “Certificate” and, collectively, the “Certificates”) whose shares were converted pursuant to Section 2.2 into shares of Finisar Common Stock, together with (i) a duly executed letter of transmittal (in a form to be provided by Finisar prior to the Closing), which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Finisar and InterSAN may reasonably specify, and (ii) instructions for use in effecting the surrender of the Certificates in exchange for shares of Finisar Common Stock, the holder of such Certificate shall be entitled to receive in exchange therefor the number of whole shares of Finisar Common Stock into which such InterSAN Capital Stock has been converted pursuant to the provisions of Section 2.2 less the number of whole Escrow Shares in respect of such InterSAN Capital Stock that is placed in escrow pursuant to Section 2.4. The Certificates so surrendered shall immediately be canceled. If requested by a holder of record of InterSAN Capital Stock in the letter of transmittal delivered to Finisar, Finisar shall cause the shares of Finisar Common Stock issued in exchange for the shares of InterSAN Capital Stock to be transferred by book entry to an account established by such holder at a broker to be identified by InterSAN who shall be reasonably acceptable to Finisar. If requested by a holder of InterSAN Common Stock acquired upon the exercise of an InterSAN Option for which InterSAN is obligated to withhold federal or state taxes, Finisar shall retain the number of shares of Finisar Common Stock otherwise issuable to such holder equal to the amount of InterSAN’s statutory tax withholding obligations in complete satisfaction of the

5

holder’s liability therefor to InterSAN and Finisar. In the event of a transfer of ownership of InterSAN Capital Stock which is not registered in the transfer records of InterSAN, the shares of Finisar Common Stock to which the holder is entitled may be issued to a transferee if the Certificate representing such InterSAN Capital Stock is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.3, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the shares of Finisar Common Stock and cash in lieu of any fractional shares of Finisar Common Stock as contemplated by this Section 2.3.

          (c) InterSAN Restricted Stock. Notwithstanding the foregoing, if any unvested shares of InterSAN Capital Stock subject to a right of repurchase by InterSAN (“InterSAN Restricted Stock”) remain outstanding immediately prior to the Effective Time, subject to the surrender of the Certificate or Certificates representing such shares of the InterSAN Restricted Stock in accordance with the foregoing terms of this Section 2.3, the shares of Finisar Common Stock into which such shares of InterSAN Restricted Stock are converted shall be held by the Secretary of Finisar subject to the terms and conditions of the agreement(s) between such holders and InterSAN (the “Restricted Stock Agreements”) until the expiration of the right of repurchase to which such shares of InterSAN Restricted Stock were subject thereunder, and Finisar shall cause the Secretary of Finisar to release such number of shares of Finisar Common Stock to the former holder of InterSAN Restricted Stock from time to time and at such time as such right of repurchase expires pursuant to, and in accordance with, the terms and conditions of the Restricted Stock Agreements.

          (d) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Finisar Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Finisar Common Stock represented thereby and no cash payment in lieu of fractional shares payable to any such holder pursuant to subsection (f) below shall be paid until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the whole shares of Finisar Common Stock issued in exchange for such Certificate, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Finisar Common Stock to which such holder is entitled pursuant to subsection (f) below and the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Finisar Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Finisar Common Stock.

          (e) No Further Ownership Rights in InterSAN Capital Stock. All shares of Finisar Common Stock delivered upon the surrender for exchange of shares of InterSAN Capital Stock in accordance with the terms hereof (including any cash paid pursuant to subsection (d) or (f) of this Section 2.3) shall be deemed to have been delivered in full satisfaction of all rights pertaining to such shares of InterSAN Capital Stock, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of InterSAN

6

Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Section 2.3.

          (f) No Fractional Shares. No fractional shares of Finisar Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a shareholder of Finisar. Notwithstanding any other provision of this Agreement, each holder of shares of InterSAN Capital Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Finisar Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Finisar Common Stock multiplied by the Finisar Share Price.

          (g) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the stockholders of InterSAN after one year after the Effective Time shall be delivered to Finisar, upon demand, and any stockholders of InterSAN who have not previously complied with this Section 2.3 shall thereafter look only to Finisar for payment of their claim for Finisar Common Stock, any cash in lieu of fractional shares of Finisar Common Stock, and any dividends or distributions with respect to Finisar Common Stock.

          (h) No Liability. Neither the Exchange Agent, Finisar nor InterSAN shall be liable to any holder of shares of InterSAN Capital Stock or Finisar Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

          (i) Lost Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, Finisar shall issue in exchange for such lost, stolen or destroyed Certificate the shares of Finisar Common Stock issuable in exchange therefor pursuant to the provisions of this Article II, together with cash, if any, in lieu of fractional shares in accordance with Section 2.3(f) hereof. The Board of Directors of Finisar may in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to provide to Finisar an indemnity agreement against any claim that may be made against Finisar with respect to the Certificate alleged to have been lost, stolen or destroyed.

     Section 2.4 Escrow.

          (a) At the Closing, or as soon as practicable after the Effective Time, Finisar will cause to be deposited into escrow (the “Escrow”) certificates representing the Escrow Shares. The Escrow Shares shall be held by U.S. Bank Trust National Association or such other financial institution as Finisar and InterSAN shall mutually determine (the “Escrow Agent”) in accordance with and subject to the provisions of an Escrow Agreement substantially in the form of Exhibit B hereto (the “Escrow Agreement”). The Escrow Shares shall be deemed to have been contributed only by holders of issued and outstanding InterSAN Capital Stock immediately prior to the Effective Time (“InterSAN Stockholders”). The percentage of the Escrow Shares contributed on behalf of each holder of InterSAN Common Stock contributing to the Escrow, as shown in a schedule to be delivered at the Closing and attached to the Escrow Agreement, shall

7

be ten percent (10%) of the shares of Finisar Common Stock entitled to be received by each such holder of InterSAN Common Stock at the Effective Time; provided, however, that if ten percent (10%) of the shares of Finisar Common Stock to be delivered to any holder of InterSAN Common Stock is less than ten (10) shares, such holder shall not be obligated to contribute shares of Finisar Common Stock to the Escrow. The percentage of the Escrow Shares contributed on behalf of each holder of InterSAN Preferred Stock contributing to the Escrow, as shown in a schedule to be delivered at the Closing and attached to the Escrow Agreement, shall be ten percent (10%) of the shares of Finisar Common Stock entitled to be received by each such holder of InterSAN Preferred Stock at the Effective Time; provided, however, that if ten percent (10%) of the shares of Finisar Common Stock to be delivered to any holder of InterSAN Preferred Stock is less than ten (10) shares, such holder shall not be obligated to contribute shares of Finisar Common Stock to the Escrow.

          (b) The Escrow Shares shall be subject to claims of indemnification under Article IX and the procedures specified in the Escrow Agreement. Subject to the provisions of Section 9.2(d), the sole recourse for claims under this Agreement shall be the Escrow Shares.

     Section 2.5 Dissenters’ Rights. In the event the Merger becomes effective without the approval of the holders of 100% of the outstanding shares of InterSAN Capital Stock, any shares of InterSAN Capital Stock held by stockholders who properly exercise and perfect the appraisal rights set forth in Section 262 of the DGCL (and, if InterSAN is subject to Section 2115 of the California Corporations Code, such rights as may be granted to persons in Chapter 13 of the California Corporations Code) (the “Dissenting Shares”) shall not be converted pursuant to Section 2.2, but shall instead be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to the provisions of the applicable law. Finisar shall have the right to control all negotiations and proceedings with respect to the determination of the appropriate value of the InterSAN Capital Stock pursuant to the applicable law. InterSAN agrees that, without the prior written consent of Finisar or as required under the applicable law, it will not voluntarily make any payment with respect to, or determine or offer to determine, the value of the InterSAN Capital Stock. Each holder of Dissenting Shares (a “Dissenting Shareholder”) who, pursuant to the provisions of the applicable law, becomes entitled to payment of the value of InterSAN Capital Stock, as determined pursuant to applicable law, shall receive payment therefor (but only after the value therefor shall have been agreed upon or finally determined pursuant to the provisions of the applicable law). In the event that any holder of InterSAN Capital Stock fails to make an effective demand for payment or otherwise loses his, her or its status as a Dissenting Shareholder, Finisar shall, as of the later of the Effective Time or the occurrence of such event, issue and deliver, upon surrender by such Dissenting Shareholder of his, her or its Certificate(s), the shares of Finisar Common Stock and cash, including any cash payment in lieu of fractional shares, in each case without interest thereon, to which such Dissenting Shareholder would have been entitled under Section 2.2.

     Section 6.3 Access to Information. Upon reasonable notice, InterSAN shall afford to the officers, employees, accountants, counsel and other representatives of Finisar, reasonable

32

access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records and, during such period, InterSAN shall promptly furnish or make available to Finisar or its representatives all other information concerning its business, properties and personnel as such other party may reasonably request. Unless otherwise required by law, the parties will treat any such information which is nonpublic in confidence in accordance with the Mutual Nondisclosure Agreement dated October 3, 2004 (the “Confidentiality Agreement”) between Finisar and InterSAN, which Confidentiality Agreement shall continue in full force and effect in accordance with its terms. No information or knowledge obtained in any investigation pursuant to this Section 6.3 shall affect or be deemed to modify any representation or warranty contained in this Agreement or the conditions to the obligations of the parties to consummate the Merger.

     Section 6.4 Legal Conditions to Merger. Each of Finisar and InterSAN will take all reasonable actions necessary to comply promptly with all legal requirements which may be imposed on itself with respect to the Merger (which actions shall include, without limitation, furnishing all information reasonably necessary in connection with approvals of or filings with any Governmental Entity) and will promptly cooperate with and furnish information to each other in connection with any such requirements imposed upon either of them or any of their Subsidiaries in connection with the Merger. Each of Finisar and InterSAN will take all reasonable actions necessary to obtain (and will cooperate with each other in obtaining) any consent, authorization, order or approval of, or any exemption by, any Governmental Entity required to be obtained or made by InterSAN, Finisar or any of their Subsidiaries in connection with the Merger or the taking of any action contemplated thereby or by this Agreement and to enable the Closing to occur as promptly as practicable.

     Section 6.5 Public Disclosure. Finisar and InterSAN shall consult with each other before issuing any press release or otherwise making any public statement with respect to the Merger or this Agreement and neither party shall issue any such press release or make any such public statement prior to receiving written consent to such press release or public statement from the other party, except as may be required by law or by the rules or regulations of the SEC or the NNM.

     Section 6.6 Tax-Free Reorganization. Finisar and InterSAN each intend that the Merger shall qualify for treatment as a reorganization within the meaning of Section 368(a) of the Code. Finisar and InterSAN each agree to refrain from taking any action prior to, on or after the Effective Time that would cause the Merger to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code. Finisar and InterSAN agree to report the Merger as a reorganization on all Tax Returns.

     Section 6.7 Nasdaq Quotation. Finisar agrees to continue the quotation of Finisar Common Stock on the NNM during the term of this Agreement. Finisar shall take all actions within its power and use its best efforts to cause the shares of Finisar Common Stock to be issued in connection with the Merger to be approved for quotation on the NNM, subject to official notice of issuance, prior to the Closing Date.

33

     Section 6.8 Securities Law Matters.

          (a) Unless Finisar elects to file a Registration Statement pursuant to Section 6.8(g) below, as soon as practicable following the execution of this Agreement, Finisar, with the cooperation of InterSAN, will file a request for a hearing (the “Hearing”) before the Commissioner of Corporations of the State of California (the “California Commissioner”) to consider the terms, conditions and fairness of the transactions contemplated by this Agreement pursuant to Section 25142 of the California Corporations Code, together with an application for a permit relating to the transactions contemplated by this Agreement and the Certificate of Merger (the “Permit”). Finisar shall take all actions reasonably required to complete the request for Hearing, the application for Permit and such other notices and documents as may be reasonably required in connection with the Hearing and the application for Permit. InterSAN shall promptly furnish to Finisar all data and information relating to InterSAN as Finisar shall reasonably determine to be necessary in connection with such request and application and such other notices and documents as may be required in connection with the Hearing and application for Permit. Finisar and InterSAN shall use their respective best efforts to cause the Hearing to take place and the Permit to be issued at the earliest practicable date.

          (b) Finisar shall prepare and file with appropriate state securities or “Blue Sky” authorities all applications for qualification or approval (or notices required to perfect exemptions from such compliance) as may be required in connection with the Merger. InterSAN shall use all reasonable efforts to assist Finisar as may be necessary to comply with all appropriate state securities or Blue Sky laws which may be applicable in connection with the Merger.

          (c) In connection with the Hearing, InterSAN shall prepare, with the cooperation of Finisar, a disclosure document (the “Consent Solicitation Statement”) describing this Agreement and the transactions contemplated hereby for the purpose of soliciting the approval of InterSAN stockholders. Finisar shall provide such information about itself as InterSAN shall reasonably request. The information supplied by InterSAN for inclusion in the Consent Solicitation Statement shall not, on the date the Consent Solicitation Statement is first mailed to InterSAN Stockholders, nor at the Effective Time, contain any statement which, at such time, is false or misleading with respect to any material fact, or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they are made, not false or misleading, or omit to state any material fact necessary to correct any statement in any earlier communication which has become false or misleading. Notwithstanding the foregoing, InterSAN makes no representation, warranty or covenant with respect to any information supplied by Finisar or Sub which is contained in any of the foregoing documents. The information supplied by Finisar for inclusion in the Consent Solicitation Statement shall not, on the date the Consent Solicitation Statement is first mailed to InterSAN’s stockholders, nor at the Effective Time, contain any statement which, at such time, is false or misleading with respect to any material fact, or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they are made, not false or misleading; or omit to state any material fact necessary to correct any statement in any earlier communication which has become false or misleading. Notwithstanding the foregoing, Finisar and Sub make no representation, warranty or covenant with respect to any information supplied by InterSAN which is contained in any of the foregoing documents.

34

          (d) The Consent Solicitation Statement shall constitute a disclosure document for the offer and issuance of shares of Finisar Common Stock to be received by the holders of InterSAN Capital Stock in the Merger. Finisar and InterSAN shall each use reasonable efforts to cause the Consent Solicitation Statement to comply with applicable federal and state securities laws requirements. Each of Finisar and InterSAN agrees to provide promptly to the other such information concerning its business and financial statements and affairs as, in the reasonable judgment of the providing party or its counsel, may be required or appropriate for inclusion in the Consent Solicitation Statement or in any amendments or supplements thereto, and to cause its counsel and auditors, if applicable, to cooperate with the other’s counsel and auditors, if applicable, in the preparation of the Consent Solicitation Statement. InterSAN will promptly advise Finisar, and Finisar will promptly advise InterSAN, in writing if at any time prior to the Effective Time either InterSAN or Finisar shall obtain knowledge of any facts that might make it necessary or appropriate to amend or supplement the Consent Solicitation Statement in order to make the statements contained or incorporated by reference therein not misleading or to comply with applicable law. The Consent Solicitation Statement shall contain the unanimous recommendation of the Board of Directors of InterSAN that the stockholders of InterSAN approve the Merger and this Agreement and the unanimous conclusion of the Board of Directors that the terms and conditions of the Merger are fair and reasonable to the stockholders of InterSAN. Anything to the contrary contained herein notwithstanding, InterSAN shall not include in the Consent Solicitation Statement any information with respect to Finisar or its affiliates or associates, the form and content of which information shall not have been approved by Finisar prior to such inclusion.

          (e) Upon receipt of the Permit, InterSAN shall, as promptly as possible but not later than three (3) days following the effectiveness of the Permit, submit this Agreement and the transactions contemplated hereby to the stockholders of InterSAN for approval and adoption as provided by the DGCL and its Certificate of Incorporation and Bylaws. InterSAN shall use all reasonable efforts to solicit and obtain the consent of the InterSAN stockholders sufficient to approve the Merger and this Agreement and to enable the Closing to occur as promptly as practicable. InterSAN shall ensure that the meeting of the stockholders of InterSAN called for the purpose of approving the Merger and this Agreement, or the solicitation of written consents of the stockholders of InterSAN without a meeting, is conducted, and that all proxies solicited by InterSAN in connection with any such meeting are solicited, in compliance with applicable law and the InterSAN charter documents. Subject to the provisions of Section 8.1(e) of this Agreement, InterSAN’s obligation to call, give notice of, convene and hold the stockholders’ meeting, or to solicit the written consent of its stockholders without a meeting, in accordance with this Section 6.8(e) shall not be limited to or otherwise affected by the commencement, disclosure, announcement or submission to InterSAN of any Acquisition Proposal.

          (f) Schedule 6.8(f) sets forth those persons who, in InterSAN’s reasonable judgment are or may be “affiliates” of InterSAN within the meaning of Rule 145 promulgated under the Securities Act (each such person a “InterSAN Affiliate”). InterSAN shall provide Finisar such information and documents as Finisar shall reasonably request in connection with Finisar’s review of such list. InterSAN shall use all reasonable efforts to deliver or cause to be delivered to Finisar, promptly following the execution of this Agreement (and in any case prior to the Closing), from each of the InterSAN Affiliates an executed Affiliate Agreement in the form attached hereto as Exhibit C. Finisar shall be entitled to place appropriate legends on the

35

certificates evidencing any Finisar Common Stock to be received by such InterSAN Affiliates pursuant to the terms of this Agreement, and to issue appropriate stop transfer instructions to the transfer agent for Finisar Common Stock, consistent with the terms of such Affiliate Agreements.

          (g) If Finisar and InterSAN mutually agree, or in the event that the California Commissioner notifies Finisar or InterSAN of the California Commissioner’s determination not to grant the Hearing, not to permit the mailing of the Hearing Notice and/or not to issue the Permit (or that any of the foregoing will be conditioned upon a material alteration to the terms of this Agreement, any exhibit or schedule hereto or the transactions contemplated hereby or thereby) (such date on which Finisar and InterSAN receive such notification, the “Notification Date”), then, Finisar shall use commercially reasonable efforts to cause the shares of Finisar Common Stock issued in the Merger (collectively, the “Registrable Securities”) to be registered under the Securities Act so as to permit the resale thereof, and in connection therewith shall use its best efforts to prepare and file with the SEC within fifteen (15) days following the Closing Date, and shall use commercially reasonable efforts to cause to become effective no later than sixty (60) days thereafter, a registration statement (the “Registration Statement”) on Form S-3 or on such successor form as is then available under the Securities Act covering the Registrable Securities; provided, however, that each holder of Registrable Securities (“Holder”) shall provide all such information and materials to Finisar and take all such action as may be required in order to permit Finisar to comply with all applicable requirements of the SEC and to obtain any desired acceleration of the effective date of such Registration Statement. Such provision of information and materials is a condition precedent to the obligations of Finisar pursuant to this Section 6.8(g). Finisar shall not be required to effect more than one (1) registration under this Section 6.8(g). The offering made pursuant to such registration shall not be underwritten. Notwithstanding the foregoing, Finisar shall be entitled to postpone the filing or declaration of effectiveness of the Registration Statement for a reasonable period of time not to exceed thirty (30) calendar days after the deadlines therefore set forth in this Section 6.8(g), if Finisar determines that there exists material nonpublic information about Finisar which would be required by the Securities Act to be disclosed in the Registration Statement, the disclosure of which, in the good faith determination of the Board of Directors of Finisar, would be detrimental to Finisar.

               Subject to the limitations of this Section 6.8(g), Finisar shall: (i) prepare and file the Registration Statement with the SEC in accordance with this Section 6.8(g) with respect to the Registrable Securities and shall take all actions within its power or control to cause the Registration Statement to become effective as promptly as practicable after filing and to keep the Registration Statement effective until twelve (12) months after the Effective Time; (ii) prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary, and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all securities proposed to be registered in the Registration Statement during the period specified in clause (i) above; and (iii) furnish to each Holder such number of copies of any prospectus (including any preliminary prospectus and any amended or supplemented prospectus) in conformity with the requirements of the Securities Act, and such other documents, as each Holder may reasonably request in order to effect the offering and sale of the Registrable Securities to be offered and sold.

36

               Notwithstanding any other provision of this Section 6.8(g), Finisar shall have the right at any time to require that all Holders suspend further open market offers and sales of Registrable Securities pursuant to the Registration Statement whenever, and for so long as, in the reasonable judgment of Finisar in good faith after consultation with counsel, there is or may be in existence material undisclosed information or events with respect to Finisar (the “Suspension Right”). In the event Finisar exercises the Suspension Right, such suspension will continue for the period of time reasonably necessary for disclosure to occur at a time that is not materially detrimental to Finisar and its stockholders or until such time as the information or event is no longer material, each as determined in good faith by Finisar after consultation with counsel. Finisar will use all reasonable efforts to limit the length of the suspension to thirty (30) calendar days or less. Finisar agrees to notify the Holders promptly upon termination of the suspension. Notwithstanding any other provision of this Section 6.8(g), in no event shall the Suspension Right be exercised (i) more than two (2) times in any 12-month period or (ii) for a total of more than ninety (90) days in any 12-month period.

               Finisar will indemnify each Holder, each of its officers and directors and partners, and each person controlling such Holder within the meaning of Section 15 of the Securities Act against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, preliminary prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any registration, qualification or compliance effected pursuant to this Section 6.8, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation or any alleged violation by Finisar of any rule or regulation promulgated under the Securities Act or the Exchange Act in connection with any such registration, qualification or compliance, and Finisar will reimburse each such Holder, each of its officers and directors, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, as such expenses are incurred, provided that Finisar will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to Finisar by such Holder or controlling person and specifically for use therein.

               It shall be a condition to Finisar’s obligations hereunder to register the Registrable Securities of any Holder that such Holder agrees to indemnify Finisar, each of Finisar’s directors and officers, each person who controls Finisar within the meaning of Section 15 of the Securities Act, and each other such Holder, each of its officers and directors and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any 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 will reimburse Finisar, such other Holders,

37

directors, officers, persons or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as such expenses are incurred, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information about such Holder or such Holder’s plans for distributing the Registrable Securities furnished to Finisar by such Holder specifically for use therein.

               Each party entitled to indemnification under this Section 6.8(g) (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party’s expense; provided, however, that an Indemnified Party (together with all other Indemnified Parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to differing or potentially differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 6.8(g) unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

               If the average of the closing prices per share of the Finisar Common Stock on the NNM over the five (5) day period ending one (1) day prior to the date on which the Registration Statement is declared effective (the “S-3 Share Price”) is less than the Finisar Share Price, Finisar shall deliver to each holder of Registrable Securities a whole number of shares of Finisar Common Stock (rounded to the nearest whole share) equal to the difference between (i) the number of shares of Registrable Securities issued to such holder at the Effective Time divided by the quotient of the S-3 Share Price and the Finisar Share Price less (ii) the number of shares of Registrable Securities issued to such holder at the Effective Time.

     Section 6.9 Employment Matters.

          (a) Effective on the Closing Date, Chris Melville and Christina Mercier (the “Key Employees”) will become employees of the Surviving Corporation pursuant to the terms of Employment Agreements in the form of Exhibit D-1 and Exhibit D-2 hereto, respectively (the “Employment Agreements”).

38

          (b) Prior to the Closing Date, Finisar will make offers of “at will” employment (on behalf of the Surviving Corporation) to all employees of InterSAN recommended by the Chief Executive Officer of InterSAN and set forth on Schedule 6.9(b) hereto, such offers to be conditioned upon the consummation of the Merger. The employment of all InterSAN employees whose employment will not be continued by the Surviving Corporation will be terminated by InterSAN prior to the Closing Date.

          (c) Prior to the Closing Date, all InterSAN employees who continue as employees of Finisar or InterSAN following the Effective Time (the “Continuing Employees”) shall have executed Finisar’s standard form of confidential information and invention assignment agreement.

          (d) Finisar agrees to maintain offices at InterSAN’s existing facility, or an equivalent facility, in Scotts Valley, California for the Continuing Employees for at least twelve (12) months following the Closing Date.

          (e) Finisar agrees to provide Continuing Employees who are terminated for reasons other than cause prior to the six (6) month anniversary of the Closing Date with their then current base salaries as set forth in the list provided to Finisar and with equivalent employee benefits as described in Section 6.10 below. For purposes of this Section 6.9(e), “Cause” means a Continuing Employee’s (i) theft, dishonesty or falsification of any documents or records of InterSAN, Finisar, the Surviving Corporation or any of their respective affiliates; (ii) breach of the employee confidential information and invention assignment agreement of InterSAN, Finisar, the Surviving Corporation or any of their respective affiliates; (iii) willful failure to perform any reasonably assigned duties after written notice from InterSAN, Finisar, the Surviving Corporation or any of their respective affiliates of, and a reasonable opportunity (not to exceed 30 days) to cure, such willful failure; (iv) conviction (including any plea of guilty or nolo contendere) of any felony or other crime(s) involving moral turpitude; or (v) repeated willful failure to abide by the workplace conduct guidelines and employee policies of InterSAN, Finisar, the Surviving Corporation or any of their respective affiliates following written notification of such willful failure.

          (f) Finisar agrees that Continuing Employees other than the Key Employees will retain their current titles as set forth in the list provided to Finisar and the current reporting structure following the Closing Date; provided, however, that Finisar shall have the right in its sole discretion to change such titles and reporting structure as necessary to implement changes in Finisar’s plans and strategies for the Surviving Corporation and Finisar following the Closing Date.

          (g) Finisar agrees to maintain the base salaries of Continuing Employees at no less than the current levels set forth in the list provided to Finisar, and in all events at the level of compensation provided to Finisar employees holding comparable positions, until the earlier of their termination of employment or a performance review in the summer of 2006.

     Section 6.10 Employee Benefits. All Continuing Employees shall be eligible to participate in those benefit plans and programs (the “Finisar Plans”) that are available to other Finisar employees holding comparable positions. To the extent permitted by the Finisar Plans or

39

as required by law, each Continuing Employee shall be given credit, for purposes of any service requirements for participation or vesting, for his or her period of continuous service with InterSAN prior to the Effective Time.

     Section 6.11 Termination of 401(k) Plan. Effective as of the day immediately preceding the Effective Time, InterSAN shall terminate any and all InterSAN Employee Plans that are subject to the requirements of Code Section 401(k) (collectively, the “401(k) Plan”) unless Finisar notifies InterSAN, in writing, no later than five (5) days prior to the Effective Time that such termination is not required. Prior to the Effective Time, InterSAN shall provide to Finisar (i) executed resolutions by InterSAN’s Board of Directors authorizing the termination of the 401(k) Plan and (ii) an executed amendment to the 401(k) Plan sufficient to assure compliance with all applicable requirements of the Code and regulations thereunder so that the tax-qualified status of the 401(k) Plan shall be maintained at the time of termination. The form and substance of such resolutions and amendment shall be subject to the prior review and approval of Finisar.

     Section 6.12 Brokers or Finders. Each of Finisar and InterSAN represents, as to itself, its Subsidiaries and its Affiliates, that no agent, broker, investment banker, financial advisor or other firm or person is or will be entitled to any broker’s or finder’s fee or any other commission or similar fee in connection with any of the transactions contemplated by this Agreement, except White Dove Partners (“White Dove”), financial advisor to Finisar. Except for the fees and expenses of White Dove which are to be paid by Finisar, each of Finisar and InterSAN agrees to indemnify and hold the other harmless from and against any and all liability for any broker’s or finder’s fee or any other commission or similar fee in connection with any of the transactions contemplated by this Agreement.

     Section 6.13 Additional Agreements; Reasonable Efforts. Subject to the terms and conditions of this Agreement, each of the parties agrees to use all reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement, including cooperating fully with the other party, including by provision of information. Without limiting the generality of the foregoing, (a) InterSAN will provide to Finisar all financial and accounting records that shall be reasonably requested by Finisar for the purpose of preparing financial statements of InterSAN for any period, or as of any date, prior to the Effective Time to the extent such financial statements are required by GAAP or the applicable rules and regulations of the SEC and (b) Finisar will take such actions as may be necessary to provide InterSAN stockholders with the Merger Consideration which they are entitled to receive hereunder within two (2) business days after receipt of the documents to be delivered by the InterSAN stockholders specified in Section 2.3(b) and will disclose information concerning the Merger to the public, if required by the rules or regulations of the SEC, within two (2) business days after the Effective Time. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of either of the Constituent Corporations, the proper officers and directors of each party to this Agreement shall take all such necessary action.

40

     Section 6.14 Expenses. The parties shall each pay their own legal, accounting, financial advisory and consulting fees and other out-of-pocket expenses related to the negotiation, preparation and carrying out of this Agreement and the transactions herein contemplated. In the event the Merger is consummated, all legal, accounting, financial advisory and consulting fees and expenses incurred by InterSAN (whether paid or accrued) relating to the negotiation, preparation and carrying out of this Agreement and the transactions contemplated hereby, and obtaining all authorizations, consents, orders or approvals of, or declarations or filings with, all Governmental Entities in connection with such transactions (the “InterSAN Transaction Expenses”) shall be paid by the Surviving Corporation; provided, however, that any InterSAN Transaction Expenses in excess of $50,000 shall be borne by the former security holders of InterSAN, as hereinafter provided. InterSAN shall provide a schedule of estimated InterSAN Transaction Expenses not later than two (2) business days prior to the Closing (the “Closing InterSAN Transaction Expense Schedule”). In the event that the Closing InterSAN Transaction Expense Schedule sets forth InterSAN Transaction Expenses in excess of $50,000 (“Excess InterSAN Transaction Expenses”), the Merger Consideration shall be reduced as set forth in Section 2.1(n). In the event that the Merger Consideration was not reduced by the full amount of Excess InterSAN Transaction Expenses pursuant to Section 2.1(n) or if any Excess InterSAN Transaction Expenses are identified after the Effective Time, Finisar shall be entitled to assert a claim against the Escrow Shares pursuant to Article IX hereof in order to recover all such Excess InterSAN Transaction Expenses.

     Section 6.15 Amendment to InterSAN’s Certificate of Incorporation. InterSAN shall use all reasonable efforts to obtain the approval by its stockholders of an amendment to its Certificate of Incorporation to provide that the liquidation preferences set forth in Article IV, Section 2 therein shall not apply to the Merger and that the allocation of the Merger Consideration shall be as set forth in this Agreement.

     Section 6.16 Waiver Agreements by Disqualified Individuals. Prior to the Effective Time and, in any event, prior to the earliest time following the date of this Agreement at which any payment or benefit which would constitute an “excess parachute payment” within the meaning of Section 280G of the Code as a consequence of any transaction or event contemplated by this Agreement (each such payment or benefit being hereinafter referred to as a “Potential Excess Parachute Payment”) in the absence of satisfaction of the shareholder approval requirements described in Section 280G(b)(5) of the Code (the “Shareholder Approval Requirements”) is paid or provided to or for the benefit of any person who, with respect to InterSAN, is a “disqualified individual” within the meaning of Section 280G(c) of the Code, InterSAN shall require such person to agree in writing, in a form reasonably acceptable to Finisar (a “Waiver Agreement”), to forfeit such person’s right to receive each and every Potential Excess Parachute Payment unless, subsequent to the date of such Waiver Agreement, the stockholders of InterSAN approve such Potential Excess Parachute Payment in compliance with the Shareholder Approval Requirements.

          (a) by the mutual written consent of Finisar and InterSAN;

          (b) by either Finisar or InterSAN if the Merger shall not have been consummated by June 30, 2005; provided, however, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose failure to fulfill any obligation or whose breach of any representation and warranty under this Agreement has been the cause of or resulted in the failure of the Merger to occur on or before such date;

          (c) by either Finisar or InterSAN if a court of competent jurisdiction or other Governmental Entity shall have issued a nonappealable final order, decree or ruling or taken any other action, in each case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger, except, if the party relying on such order, decree or ruling or other action has not complied with its obligations under Section 6.4 of this Agreement;

          (d) by Finisar if the Board of Directors of InterSAN shall have withdrawn or modified its recommendation of this Agreement or the Merger for approval by the InterSAN stockholders in a manner adverse to Finisar or shall have publicly announced or disclosed to any third party its intention to do any of the foregoing;

In the event of termination of this Agreement as provided in Section 8.1, there shall be no liability or obligation on the part of Finisar, InterSAN, Sub or their respective officers, directors, stockholders or Affiliates, except to the extent that such termination results from the willful breach by a party of any of its covenants set forth in this Agreement, except that the provisions of Sections 6.12 and 6.14 of this Agreement and the confidentiality provisions set forth herein and in the Confidentiality Agreement shall remain in full force and effect and survive any termination of this Agreement.

45

     Section 8.3 Amendment. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the stockholders of InterSAN, but, after any such approval, no amendment shall be made which by law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

     Section 8.4 Extension; Waiver.

ARTICLE IX

ESCROW AND INDEMNIFICATION

     Section 9.1 Survival of Representations and Warranties. If the Merger occurs, all of the representations and warranties contained in this Agreement shall survive the Closing Date for a period of twelve (12) months following the Closing Date (the “Termination Date”).

     Section 9.2 Indemnification.

          (a) Subject to the terms and conditions contained in this Article IX, Finisar, its officers, directors, employees, agents and attorneys, all Subsidiaries and Affiliates of Finisar, and the respective officers, directors, employees, agents and attorneys of such entities (all such persons and entities being collectively referred to as the “Finisar Group”) shall be entitled to recover from the Escrow any and all losses, damages, costs and expenses (including reasonable legal fees and expenses) which any member of the Finisar Group may sustain or incur which are caused by or arise out of (i) any inaccuracy in or breach of any of the representations, warranties or covenants made by InterSAN in this Agreement, including the InterSAN Disclosure Schedule, (ii) any Excess InterSAN Transaction Expenses that are not reflected in the calculation of the Net Merger Consideration, or (iii) any breach of this Article IX or the Escrow Agreement (collectively, “Finisar Losses”).

          (b) No member of the Finisar Group shall be entitled to recover any Finisar Losses unless the aggregate amount of all Finisar Losses under all claims are equal to or greater than $50,000 and no Indemnification Claim shall be made for individual amounts of less than $10,000. Funds shall be released from the Escrow on a dollar for dollar basis for claims in excess of $50,000 in the case of Finisar Losses under Section 9.2(a)(i) and for the full amount of all Finisar Losses under Section 9.2(a)(ii). The aggregate amount which may be recovered by the Finisar Group for all Finisar Losses shall not exceed the Escrow Shares, except as otherwise provided in Section 9.2(d) below.

46

          (c) The right of a member of the Finisar Group to recover a Finisar Loss under this Article IX is subject to the condition that the Stockholders’ Representative (as defined in Section 9.6) shall have received written notice of an Indemnification Claim (as defined in Section 9.3) for such Finisar Loss on or before the Termination Date.

          (d) The provisions of Section 9.5 below shall not limit, in any manner, any remedy at law or in equity to which any member of the Finisar Group shall be entitled against InterSAN or any stockholder of InterSAN as a result of willful fraud or intentional misrepresentation by InterSAN, any stockholder of InterSAN or any of their respective representatives. The InterSAN stockholders shall be severally and not jointly liable for any such remedy at law or in equity.

          (e) The amount of Finisar Losses shall be computed after giving effect to the receipt of any insurance proceeds and tax benefits with respect thereto.

     Section 9.3 Procedures for Indemnification.

          (a) As used in this Article IX, the term “Indemnitee” means the member or members of the Finisar Group seeking recovery from the Escrow.

          (b) A claim for indemnification hereunder (an “Indemnification Claim”) shall be made by Indemnitee by delivery of a written notice signed by an executive officer of Finisar to the Stockholders’ Representative and the Escrow Agent requesting indemnification and specifying in reasonable detail the basis on which indemnification is sought (and shall include relevant documentation related to the Indemnification Claim), the amount of the asserted Finisar Losses and, in the case of a Third Party Claim (as defined in Section 9.4), containing (by attachment or otherwise) such other information as Indemnitee shall have concerning such Third Party Claim.

          (c) If the Indemnification Claim involves a Third Party Claim, the procedures set forth in Section 9.4 hereof shall be observed by Indemnitee and the Stockholders’ Representative.

     Section 9.4 Defense of Third Party Claims. Should any claim be made or suit or proceeding be instituted against an Indemnitee which, if prosecuted successfully, would be a matter for which such Indemnitee is entitled to indemnification under this Article IX (a “Third Party Claim”), the obligations and liabilities of the parties hereunder with respect to the portions of such Third Party Claims that are covered by the indemnification provisions in this Article IX (but excluding all other portions of such Third Party Claims and all counterclaims and the like by the Indemnitee or its affiliates) shall be subject to the following terms and conditions:

          (a) Indemnitee shall give the Stockholders’ Representative and the Escrow Agent written notice of any such Third Party Claim promptly after receipt by Indemnitee of notice thereof, and the Stockholders’ Representative may undertake control of the defense thereof by counsel of its own choosing, which counsel shall be reasonably acceptable to the Indemnitee. In such event, Indemnitee may participate in the defense through its own counsel at its own expense. If, however, the Stockholders’ Representative fails or refuses to undertake the defense of such Third Party Claim within twenty (20) days after written notice of such claim has

47

been delivered to the Stockholders’ Representative by Indemnitee, Indemnitee shall have the right to undertake the defense, compromise and, subject to Section 9.5, settlement of such Third Party Claim with counsel of its own choosing. Failure of Indemnitee to furnish written notice to the Stockholders’ Representative or the Escrow Agent of a Third Party Claim shall not release the InterSAN Stockholders from their obligations hereunder, except to the extent they are prejudiced by such failure.

          (b) Indemnitee and the Stockholders’ Representative shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available records relating to such claim and furnishing employees of Indemnitee as may be reasonably necessary for the preparation of the defense of any such Third Party Claim or for testimony as witness in any proceeding relating to such claim.

          (c) Unless the Stockholders’ Representative has failed to fulfill its obligations under this Article IX, no settlement by Indemnitee of a Third Party Claim shall be made without the prior written consent by or on behalf of the Stockholders’ Representative, which consent shall not be unreasonably withheld or delayed. If the Stockholders’ Representative has assumed the defense of a Third Party Claim as contemplated by this Section 9.4, no settlement of such Third Party Claim may be made by the Stockholders’ Representative without the prior written consent by or on behalf of Indemnitee, which consent shall not be unreasonably withheld or delayed.

     Section 9.5 Manner of Indemnification.

          (a) The Escrow Shares deposited into Escrow pursuant to the Escrow Agreement in accordance with the provisions of Section 2.5 shall provide a fund against which members of the Finisar Group may assert claims of indemnification under this Article IX. Except as specifically provided in Section 9.2(d), the sole recourse of any member of the Finisar Group for claims with respect to this Agreement or the transactions contemplated by this Agreement is to the Escrow Shares.

          (b) Each claim asserted against the InterSAN Stockholders pursuant to this Article IX shall be made only in accordance with the procedures set forth herein and in the Escrow Agreement, subject to the provisions of Section 9.2(d) hereof.

     Section 9.6 Appointment of Stockholders’ Representative. For purposes of this Agreement, the InterSAN Stockholders hereby consent to the appointment of Ned Carlson as the representative and attorney-in-fact for and on behalf of the InterSAN Stockholders (the “Stockholders’ Representative”), and to the taking by the Stockholders’ Representative of any and all actions and the making of any decisions required or permitted to be taken by him under this Agreement or the Escrow Agreement, including, without limitation, the exercise of the power to (i) execute the Escrow Agreement on behalf of the InterSAN Stockholders, (ii) authorize delivery to Finisar of Escrow Shares in satisfaction of Indemnification Claims, (iii) agree to, negotiate, enter into settlements and compromises of and comply with orders of courts and awards of arbitrators with respect to such Indemnification Claims, (iv) resolve any Indemnification Claims and (v) take all actions necessary in the judgment of the Stockholders’ Representative for the accomplishment of the foregoing and all of the other terms, conditions and

48

limitations of this Agreement and the Escrow Agreement. Accordingly, the Stockholders’ Representative has unlimited authority and power to act on behalf of each InterSAN Shareholder with respect to the Escrow Agreement and the disposition, settlement or other handling of all Indemnification Claims. Each InterSAN Stockholder will be bound by all actions taken by the Stockholders’ Representative in connection with all Indemnification Claims, and Finisar shall be entitled to rely on any action or decision of the Stockholders’ Representative or taken by any person that Finisar reasonably believes to be authorized to act on behalf of the Stockholders’ Representative. The Stockholders’ Representative will incur no liability with respect to any action taken or suffered by it in reliance upon any notice, direction, instruction, consent, statement or other document believed by it to be genuine and to have been signed by the proper person (and shall have no responsibility to determine the authenticity thereof), nor for any other action or inaction, except his own willful misconduct or bad faith. In all questions arising under this Agreement or the Escrow Agreement, the Stockholders’ Representative may rely on the advice of counsel, and the Stockholders’ Representative will not be liable to anyone for anything done, omitted or suffered in good faith by the Stockholders’ Representative based on such advice. Except as expressly provided herein, the Stockholders’ Representative will not be required to take any action involving any expense unless the payment of such expense is made or provided for in a manner satisfactory to him. The expenses of the Stockholders’ Representative shall be paid from the Escrow Shares to the extent any Escrow Shares are available after payment of all Finisar Losses under this Article IX. At any time during the term of the Escrow Agreement, holders of a majority of the Escrow Shares then held in Escrow may, by written consent, appoint a new representative as the Stockholders’ Representative by sending notice and a copy of the written consent appointing such new representative signed by holders of a majority of the Escrow Shares to Finisar and the Escrow Agent. Such appointment will be effective upon the later of the date indicated in the consent or the date such consent is received by Finisar and the Escrow Agent. The Stockholders’ Representative may resign at any time. Upon the resignation of the Stockholders’ Representative, a successor, who shall be bound by all of the terms of this Section 9.6, shall be named pursuant to Section 11 of the Escrow Agreement.
