        NOW, THEREFORE, in consideration of the mutual promises and the mutual covenants and agreements contained herein, the parties agree as follows:

The "Expiration Date" shall mean the earlier of (i) the date and time on which the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement, (ii) the date and time on which the Merger Agreement shall be terminated pursuant to its terms, or (iii) the date and time on which an Optium Board Recommendation Change (as defined in the Merger Agreement) occurs. Notwithstanding the foregoing, the Stockholder may make (a) transfers by will or by operation of law, in which case this Agreement shall bind the transferee, (b) transfers in connection with estate and charitable planning purposes, including transfers to relatives, trusts, and charitable organizations, subject to the transferee agreeing in writing to be bound by the terms of, and perform the obligations of the Stockholder under, this Agreement and the Proxy (as defined in Section 3), (c) transfers to Optium to satisfy withholding tax obligations upon the vesting of shares of restricted stock and (d) any sale of Shares issuable upon exercise of a stock option that would otherwise expire in accordance with its terms but for the exercise thereof if such sale is effected substantially concurrently with such exercise and in compliance with Optium's policies and applicable law.

        2.    Agreement to Vote Shares.    At any meeting of the Optium stockholders called with respect to any of the following, and at any adjournment thereof, and with respect to any written consent solicited with respect to any of the following, the Stockholder agrees to vote the Shares: (i) in favor of the adoption and approval of the Merger Agreement and the Merger and all other transactions contemplated by the Merger Agreement as to which stockholders of Optium are called upon to vote or consent and (ii) against (A) approval of any proposal made in opposition to or in competition with consummation of the Merger and the Merger Agreement, (B) any merger, consolidation, sale of assets, reorganization or recapitalization involving Optium (other than the Merger), and (C) any liquidation, dissolution or winding up of Optium (each of the foregoing being referred to as an "Opposing Proposal"). The Stockholder, as the holder of voting stock of Optium agrees to be present, in person or

---

by proxy, at all meetings of stockholders of Optium which relate to the Merger or an Opposing Proposal so that all Shares are counted for the purposes of determining the presence of a quorum at such meetings. This Agreement is intended to bind the Stockholder only with respect to the specific matters set forth herein, and shall not prohibit the Stockholder from acting in accordance with any fiduciary duties the Stockholder may have as an officer or director of Optium.

        3.    Irrevocable Proxy.    Concurrently with the execution of this Agreement, the Stockholder agrees to deliver to Finisar a proxy in the form attached hereto as Annex A (the "Proxy"), which shall be irrevocable to the extent provided therein; provided that the Proxy shall be automatically revoked upon termination of this Agreement in accordance with its terms.

        5.1    Ownership of Shares.    Except as specifically described on Annex B to this Agreement, the Stockholder (i) is the holder and beneficial owner of the Shares, which at the date hereof and at all times until the Expiration Date will be free and clear of any liens, claims, options, charges or other encumbrances, (ii) does not beneficially own any shares of stock of Optium other than the Shares and (iii) has full power and authority to make, enter into, deliver and carry out the terms of this Agreement and the Proxy.

        5.2    Validity; No Conflict.    This Agreement constitutes the legal, valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting or relating to creditors' rights generally and by general principles of equity. Neither the execution of this Agreement by the Stockholder nor the consummation of the transactions contemplated hereby will result in a breach or violation of the terms of any agreement by which the Stockholder is bound or of any decree, judgment, order, law or regulation now in effect of any court or other governmental body applicable to the Stockholder.

        5.3    No Voting Trusts or Agreements.    Between the date of this Agreement and the Expiration Date, the Stockholder will not, and will not permit any entity under the Stockholder's control to, deposit any shares of Optium capital stock held by the Stockholder or such entity in a voting trust or subject any shares of Optium capital stock held by the Stockholder or such entity to any arrangement or agreement with respect to the voting of such shares of capital stock, other than agreements entered into with Finisar, unless the trustee of such trust agrees in writing to be bound by the terms of this Agreement.

        5.4    No Proxy Solicitations.    Between the date hereof and the Expiration Date, the Stockholder will not (a) solicit proxies or become a participant in a "solicitation" (as such term is defined in Rule 14a-11 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) with respect to an Opposing Proposal, (b) initiate a stockholders' vote or action by written consent of Optium stockholders with respect to an Opposing Proposal or (c) become a member of a "group" (as such term is used in Section 13(d) of the Exchange Act) with respect to any voting securities of Optium with respect to an Opposing Proposal.

        6.    Representations, Warranties and Covenants of Finisar.    Finisar represents, warrants and covenants to the Stockholder as follows:

        6.2    Validity; No Conflict.    This Agreement constitutes the legal, valid and binding obligation of Finisar, enforceable against Finisar in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting or relating to creditors' rights generally and by general principles of equity. Neither the execution of this Agreement by Finisar nor the consummation of the transactions contemplated hereby will result in a breach or violation of the terms of any agreement by which Finisar is bound or of any decree, judgment, order, law or regulation now in effect of any court or other governmental body applicable to Finisar.

        7.    Additional Documents.    The Stockholder and Finisar hereby covenant and agree to execute and deliver any additional documents necessary or desirable, in the reasonable opinion of Finisar's legal counsel or the Stockholder, as the case may be, to carry out the intent of this Agreement.

        8.    No Agreement Until Executed.    Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement and/or the Proxy shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the Board of Directors of Optium has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the certificate of incorporation of Optium, the possible consummation of the Merger, (b) the Merger Agreement is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

        9.2    Binding Effect and Assignment.    This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the parties hereto may be assigned by any of the parties without the prior written consent of the other.

        9.3    Amendments and Modifications.    This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by the parties hereto.

        9.4    Specific Performance: Injunctive Relief.    The parties hereto acknowledge that Finisar will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of the Stockholder set forth herein. Therefore, it is agreed that, in addition to any other remedies which may be available to Finisar upon such violation, Finisar shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to it at law or in equity.
