(a) Sellers agree that in accordance with Section 2.02(e), at the Closing, share certificates for 2,447,583 shares of Optium Series D-1 Preferred Stock ("SERIES D-1 ESCROW SHARES") and 875,238 shares of Optium NV Common Stock (the "COMMON ESCROW SHARES", and together with the Series D-1 Escrow Shares, the "ESCROW SHARES" or the "ESCROW") shall be held by Optium in Escrow in accordance with the terms of this Agreement. All shares of Optium Stock held by Optium in Escrow shall be applied by Optium in accordance with the terms of this Agreement to make any payments due to Optium under Section 10.02 and/or, at the sole option of Optium, under Section 2.03(e). The Escrow Shares may only be cancelled by Optium or delivered to the Sellers, as applicable. (b) Any shares of Optium's capital stock issued or distributed upon any stock split, stock dividend or recapitalization effected by Optium after the Closing Date (the "NEW SHARES") in respect of any Escrow Shares that have not been released from the Escrow shall be added to the Escrow and be deemed a part thereof and shall be deemed "Escrow Shares" for all purposes hereof. New Shares issued in respect of Escrow Shares which have been released from the Escrow shall not be added to the Escrow, but shall be distributed to the record holders thereof. Cash dividends on Escrow Shares shall not be added to the Escrow but shall be distributed to the record holders thereof. In the event that Optium shall effect a combination of its shares of capital stock after the Closing Date, Optium shall take such necessary action to effect a proportionate applicable combination and reissuance of the Escrow Shares held in escrow. Subject to the terms and conditions of this Agreement, each Seller shall be deemed the 12 record holder of, and shall have voting, dividend, distribution and all other rights with respect to the Escrow Shares held in escrow on behalf of such Seller (including any New Shares added to the Escrow in respect of such Escrow Shares). Each Seller shall have the right to direct Optium to vote the Escrow Shares held on his or her behalf in the manner that such Seller so chooses. (c) From time to time an Optium Indemnified Party (as defined in Section 10.02) may give notice in accordance with Section 10.04 hereof of a claim for indemnification, specifying the nature (in reasonable detail) and amount, in U.S. dollars, of any claim for indemnification under Article X of this Agreement. If the Seller's Representative concedes liability (subject to prior agreement in writing by each of the Major Engana Investors), the Seller's Representative shall deliver to Optium instructions that the number of Escrow Shares being held in escrow equal in value (with each Escrow Share being deemed to have a value of $0.617029 for this purpose only) to the amount claimed in the such notice should be released from Escrow and transferred back to Optium for cancellation and that new certificates evidencing the balance of the Escrow Shares should be issued in the name of Optium and the old certificates cancelled. No earlier than 11 days following dispatch of instructions from the Seller's Representative in accordance with Section 10.04(b), Optium shall cancel the original stock certificates and issue two new stock certificates, a single certificate evidencing the balance Series D-1 Escrow Shares and a single certificate evidencing the balance Common Escrow Shares, each registered in the name of the Optium and held by Optium in escrow. For each claim 73.66% of the total value of such claim shall be released from the Series D-1 Escrow Shares and 26.34% of the total value of such claim shall be released from the Common Escrow Shares. Notwithstanding any of the foregoing, any Seller may elect to make payment of their pro rata portion of any claim in cash by notifying Optium and the Seller's Representative promptly following receipt by such Seller of the instructions of the Seller's Representative described above and no later than ten (10) days following the dispatch of such notice. If any Seller or Sellers make such election to pay for their pro rata portion of any claim with cash, Optium shall, following the receipt of instructions from the Seller's Representative in accordance with Section 10.04(b), cancel the original stock certificates and issue (i) two new stock certificates, a single certificate evidencing the balance Series D-1 Escrow Shares and a single certificate evidencing the balance Common Escrow Shares, each registered in the name of Optium and held by Optium in escrow and (ii) two new stock certificates for each Seller electing to make payment of their pro rata portion of any claim in cash, a single certificate evidencing such Seller's pro rata portion of the Series D-1 Escrow Shares released in connection with such claim and a single certificate evidencing such Seller's pro rata portion of the Common Escrow Shares released in connection with such claim, as and if applicable, each registered in the name of such Sellers and delivered to the Seller's Representative. (d) As promptly as practicable following the release of any Escrow Shares from the Escrow, Optium shall send a written statement to each applicable Seller and the Seller's Representative stating the number of Escrow Shares released and the number of Escrow Shares remaining in the Escrow for the benefit of each Seller Indemnifying Party (as defined in Section 10.02). (e) Upon the Expiration Date (as defined in Section 10.01(b)) and Optium's receipt of written notice and instructions from the Seller's Representative, Optium shall transfer 13 and deliver certificates representing the number of Escrow Shares then remaining in the Escrow to the Seller's Representative, allocated to each Seller based on their pro rata percentages as set forth opposite each such holder's name on SCHEDULE 2.01(b)(ii) hereto (as may be adjusted to reflect any previous determination of any Seller to satisfy any claim by the payment of cash in accordance with Section 2.05(c)), unless any claims are then pending against the Escrow, in which case the number of Escrow Shares to be distributed shall be reduced by the number of Escrow Shares equal in value to the aggregate amount of such claims, pending their resolution in accordance with this Section 10.04 hereof. No new or additional claims may be made by Optium after the Expiration Date. On or before the third Business Day following the resolution of all claims outstanding on Expiration Date, Optium shall deliver any certificates evidencing remaining Escrow Shares held in escrow to the Seller's Representative allocated to each Seller based on their pro rata percentages as set forth opposite each such Seller's name on SCHEDULE 2.01(b)(ii) hereto (as may be adjusted to reflect any previous determination of any Seller to satisfy any claim by payment of cash in accordance with Section 2.05(c)). (f) Any delivery of Escrow Shares to the Seller's Representative required hereunder shall be sent by personal delivery, overnight (up to a maximum of 3 days) delivery by a recognized courier or delivery service to the Sellers at their respective address set forth on SCHEDULE 2.01(a)(i) hereto (or to such other address as any such party may hereafter designate by written notice to the other parties). 2.06. FURTHER ASSURANCES; POST-CLOSING COOPERATION. At any time or from time to time after the Closing, each Seller shall execute and deliver to Optium such other documents and instruments, provide such materials and information and take such other actions as Optium may reasonably request more effectively to vest title to the Shares owned and conveyed by such Seller in and to Optium and to the full extent permitted by Law to put Optium in actual possession and control of the Shares. At any time or from time to time after the Closing, Opium shall execute and deliver to Sellers such other documents and instruments, provide such materials and information and take such other actions as Sellers or Company Optionees may reasonably request more effectively to effect the issuance of the Optium Stock or Company Stock Options to be issued hereunder to the Sellers and Company Optionees and to the full extent permitted by Law to put the Sellers and Company Optionees in actual possession and control of the shares of Optium Stock or the Company Stock Options, as applicable.

CAPITALIZATION. Optium's fully-diluted, fully-converted capitalization immediately prior to the Closing consists of approximately 213,570,235 shares of Optium Common Stock (calculated on an as-converted to Optium Common Stock basis and including shares of Optium Common Stock (or shares convertible into Optium Common Stock) subject to outstanding options to purchase such shares or shares available for issuance pursuant to Optium's equity incentive plans other than as set forth in the next sentence), not including the Escrow Shares and any of the shares or options listed on Schedules 2.01(b)(i), 2.01(b)(iii), and 7.02. For further clarification, such number noted in the first sentence of this Section 5.05 does not include any shares or stock options that are to be issued as set forth in this Agreement. Of such shares, 24,268,500 shares are Series A Convertible Preferred Stock including warrants convertible therefor, convertible into approximately 28,665,553 shares of Optium Common Stock, 41,969,418 shares are Series B Convertible Preferred Stock convertible into approximately 59,598,520 shares of Optium Common Stock, 60,467,087 shares are Series C Senior Convertible Preferred Stock including warrants convertible therefor, convertible into 60,467,087 shares of Optium Common Stock, 25,245,570 shares are Series D Senior Convertible Preferred Stock convertible into 25,245,570 shares of Common Stock, and none are Series D-1 Preferred Stock. The balance of the shares included in Optium's fully-diluted, fully-converted capitalization are comprised of outstanding shares of Optium Common Stock (voting and non-voting), issued options to purchase Optium Common Stock (voting and non-voting) and shares of Optium Common Stock (voting and non-voting) available for issuance pursuant to Optium's equity incentive plans. Optium anticipates that in the near future it will increase the number of shares of Optium Common Stock (voting and non-voting) issuable pursuant to its equity incentive plans. No adjustment to the number of shares of Optium Stock issuable hereunder will be made as a result of any such increase. 5.06. FINANCIAL STATEMENTS.

Accordingly, effective after the Closing and subject to the time limits set forth in Section 10.01 above and the limitations set forth in Section 10.03 below, each of the Sellers, severally and not jointly, on his, her or its own behalf and on behalf of his or her successors, executors, administrators, estate, heirs and assigns (collectively, for the purposes of this Section 10.02, the "SELLER INDEMNIFYING PARTIES", and each individually, a "SELLER INDEMNIFYING PARTY") (or, at the sole option of Optium with respect to any matter subject to indemnification under this Section 10.02, the Company) agree (on a pro-rata basis, based on the proportion that the number of shares of Optium Stock received by each such Seller in connection with the transactions contemplated hereby bears to the number of shares of Optium Stock received by all Sellers in connection with the transactions contemplated hereby) to defend, indemnify and hold Optium, their respective Affiliates (including, effective as of the Closing, the Company) and direct and indirect partners (including partners of partners and stockholders and members of partners), members, stockholders, directors, officers, employees and agents and each person who controls any of them within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (collectively, the "OPTIUM INDEMNIFIED PARTIES" and, individually, an "OPTIUM INDEMNIFIED PARTY") harmless from and against any and all damages (other than punitive damages), liabilities, losses, claims, diminution of value, obligations, liens, assessments, judgments, Taxes, fines, penalties, reasonable costs and expenses (including, without limitation, reasonable fees of a single counsel representing the Optium Indemnified Parties), as the same are incurred, of any kind or nature whatsoever (whether or not arising out of third-party claims and including all amounts paid in investigation, defense or settlement of the foregoing) (other than with respect to and to the extent a payment is made with respect thereto pursuant to Section 2.03, "LOSSES") which may be sustained or suffered by any such Optium Indemnified Party based upon, arising out of, or by reason of any breach of: (a) any representation or warranty made by the Company in Article III of this Agreement or by the Company in a certificate provided in connection with the Closing pursuant to Article IX; or (b) any covenant or other agreement made by the Company in Article VI or elsewhere in this Agreement. 49 Payment of any amount to which an Optium Indemnified Party is entitled shall be made by release of Escrow Shares from the Escrow to Optium for cancellation; PROVIDED, that any one Seller may make such payment in cash by a certified or official bank check payable to Optium and in accordance with Section 2.05 hereof. For this purpose, each share of Optium Stock (whether Optium NV Common Stock or Optium Series D-1 Preferred Stock) shall be deemed to have a value equal to $0.617029 per share (as may be equitably adjusted in the future as a result of any stock split, stock dividend, recapitalization and the like). 10.03. LIMITATIONS ON INDEMNIFICATION. Notwithstanding anything in Section 10.02 to the contrary: (a) None of the Seller Indemnifying Parties shall be liable for Losses in respect of claims made by any Optium Indemnified Party for indemnification for breaches of representations and warranties under Section 10.02 above unless and to the extent the total of all Losses in respect of claims made by the Optium Indemnified Parties for indemnification shall exceed $100,000 in the aggregate (the "THRESHOLD") after which the full amount of Losses shall be recoverable, including such $100,000; (b) the maximum aggregate amount for which the Company and the Seller Indemnifying Parties shall be liable to all Optium Indemnified Parties taken together for Losses under Section 10.02 shall not exceed the initial amount of the Escrow (the "CAP") (with each share of Optium Stock (whether Optium NV Common Stock or Optium Series D-1 Preferred Stock) being deemed to have a value of $0.617029 for this purpose only); (c) the maximum aggregate amount for any Seller shall be liable to all Optium Indemnified Parties taken together for Losses under Section 10.02 shall not exceed the amount the number of such Seller's shares of Optium Stock included in the Escrow (the "INDIVIDUAL CAP"); and (d) None of the Seller Indemnifying Parties shall be liable for Losses in respect of claims made by any Optium Indemnified Party for indemnification for breaches of representations and warranties under Section 10.02(a) above with respect to breaches (i) consciously Known to Optium at the time of the signing of this Agreement, (ii) that would have been Known to Optium had Optium performed a search of the public register of the Australian Securities & Investment Commission, a search of the public registers of the Supreme Court of New South Wales and the Federal Court of Australia two (2) Business Days prior to Closing or (iii) that would have been Known to Optium had Optium performed proprietor searches of Engana Pty Limited on the publicly available databases of IP Australia two (2) Business Days prior to Closing. 10.04. NOTICE; DEFENSE OF THIRD-PARTY CLAIMS. (a) An Optium Indemnified Party shall give written notice of a claim for indemnification under Section 10.02 to the Seller's Representative, each Seller and Optium promptly after receipt of any written claim by any third party and in any event not later than 20 Business Days after receipt of any such written claim (or not later than ten (10) Business Days 50 after the receipt of any such written claim in the event such written claim is in the form of a formal complaint filed with a court of competent jurisdiction and served on the Optium Indemnified Party), specifying in reasonable detail the amount, nature and source of the claim, and including therewith copies of any notices or other documents received from third parties with respect to such claim; PROVIDED, HOWEVER, that failure to give such notice shall not limit the right of a Optium Indemnified Party to recover indemnity or reimbursement except to the extent that the Seller Indemnifying Party suffers any material prejudice or material harm with respect to such claim as a result of such failure. The Optium Indemnified Party shall also provide the Seller's Representative and the Sellers with such further information concerning any such claims as the Seller's Representative or an applicable Seller may reasonably request by written notice. (b) Within ten (10) Business Days after receiving notice of a claim for indemnification or reimbursement, the Seller's Representative shall (upon direction of all Major Engana Investors), by written notice to the Optium Indemnified Party, either (i) concede or deny liability for the claim in whole or in part, or (ii) in the case of a claim asserted by a third party, advise that the matters set forth in the notice are, or will be, subject to contest or legal proceedings not yet finally resolved. If the Seller's Representative concedes liability in whole or in part, it shall, within 20 Business Days of such concession, instruct Optium to pay the amount of the claim to the Optium Indemnified Party to the extent of the liability conceded and the number of Escrow Shares to be released from Escrow to Optium in accordance with Section 2.05 hereof. If the Seller's Representative does not respond or denies liability in whole or in part or advises that the matters set forth in the notice are, or will be, subject to contest or legal proceedings not yet finally resolved, then both Optium and the Seller's Representative shall take no actions to effect the release of any Escrow Shares (except for the amount of any conceded liability as set forth above) until the matter is resolved in accordance with this Agreement. (c) In the case of any third party claim, if, within ten (10) Business Days after receiving the notice described in the preceding paragraph (a), the Seller Indemnifying Party gives written notice to the Optium Indemnified Party stating that the Seller Indemnifying Party would be liable under the provisions hereof for indemnity in the amount of such claim if such claim were valid and that the Seller Indemnifying Party disputes and intends to defend against such claim, liability or expense at the Seller Indemnifying Party's own cost and expense, then counsel for the defense shall be selected by the Seller Indemnifying Party (subject to the consent of such Optium Indemnified Party which consent shall not be unreasonably withheld) and such Seller Indemnifying Party shall not be required to make any payment to the Optium Indemnified Party with respect to such claim, liability or expense as long as the Seller Indemnifying Party is conducting a good faith and diligent defense at its own expense; PROVIDED, HOWEVER, that the assumption of defense of any such matters by the Seller Indemnifying Party shall relate solely to the claim, liability or expense that is subject or potentially subject to indemnification. If the Seller Indemnifying Party assumes such defense in accordance with the preceding sentence, it shall have the right, with the consent of such Optium Indemnified Party, which consent shall not be unreasonably withheld, to settle all indemnifiable matters related to claims by third parties which are susceptible to being settled PROVIDED the Seller Indemnifying Party's obligation to indemnify such Optium Indemnified Party therefor will be fully satisfied only by payment of money by the Seller Indemnifying Party pursuant to a settlement which includes a complete release of such Optium Indemnified Party. The Seller Indemnifying Party shall keep such 51 Optium Indemnified Party apprised of the status of the claim, liability or expense and any resulting suit, proceeding or enforcement action, shall furnish such Optium Indemnified Party with all documents and information that such Optium Indemnified Party shall reasonably request and shall consult with such Optium Indemnified Party prior to acting on major matters, including settlement discussions. Notwithstanding anything herein stated, such Optium Indemnified Party shall at all times have the right to fully participate in such defense at its own expense directly or through counsel; PROVIDED, HOWEVER, if the named parties to the action or proceeding include both the Seller Indemnifying Party and the Optium Indemnified Party and representation of both parties by the same counsel would be inappropriate under applicable standards of professional conduct, the reasonable expense of separate counsel for such Optium Indemnified Party shall be paid by the Seller Indemnifying Party PROVIDED that such Seller Indemnifying Party shall be obligated to pay for only one counsel for the Optium Indemnified Party in any jurisdiction. If no such notice of intent to dispute and defend is given by the Seller Indemnifying Party, or if such diligent good faith defense is not being or ceases to be conducted, such Optium Indemnified Party may undertake the defense of (with counsel selected by such Optium Indemnified Party), and shall have the right to compromise or settle, such claim, liability or expense (exercising reasonable business judgment) and after seeking the consent of the Seller Indemnifying Parties (which consent shall not be unreasonably withheld). If such claim, liability or expense is one that by its nature cannot be defended solely by the Seller Indemnifying Party, then such Optium Indemnified Party shall make available all information and assistance that the Seller Indemnifying Party may reasonably request and shall cooperate with the Seller Indemnifying Party in such defense. 10.05. LIMITATION ON CONTRIBUTION AND CERTAIN OTHER RIGHTS; OTHER LIMITATIONS. (a) The Company and the Sellers hereby agree that if, following the Closing, any claim is made by any Seller, or otherwise becomes due from any Seller, pursuant to this Article X in respect of any Losses (a "LOSS PAYMENT"), such Seller shall have no rights against the Company, or any director, officer or employee thereof (in their capacity as such except in relation to an act of fraud (provided that the applicable individual does not have a right to indemnification or contribution from the Company)), whether by reason of contribution, indemnification, subrogation or otherwise, in respect of any such Loss Payment, and shall not take any action against the Company or any such person with respect thereto. (b) With respect to any claim(s) made by a Seller the basis of which is applicable to all Sellers, Optium shall not be liable for Losses in respect of such claim(s) made unless and to the extent that the Losses in respect of such claim(s) made by the Seller shall exceed the product of (i) $100,000 and (ii) such Seller's Pro Rata Share (as defined herein)(such product, the "MINIMUM CLAIM AMOUNT"), after which the full amount of Losses shall be recoverable, including such Minimum Claim Amount. 10.06. CLAIMS AGAINST SELLERS AND COMPANY OPTIONEES AND AGAINST OPTIUM. Optium will have all rights and remedies under applicable law with respect to Losses resulting from any breaches of representations and warranties made by each of the Sellers and the Company Optionees in Article IV of this Agreement PROVIDED that (i) the maximum amount any Seller shall be liable to Optium as a Seller, other than in the case of fraud by that Seller, shall not exceed the 52 amount of the number of shares of Optium Stock such Seller has received pursuant to this Agreement, including the shares of Optium Stock held in escrow and (ii) the maximum amount any Company Optionee shall be liable to Optium as a Company Optionee, other than in the case of fraud by that Company Optionee, shall not exceed the transfer to the Company of (1) all outstanding Optium Stock Options issued to such Company Optionee and (2) the Optium Stock issued upon exercise of such Optium Stock Options. For this purpose, each share of Optium Stock (whether Optium NV Common Stock or Optium Series D-1 Preferred Stock) shall be deemed to have a value equal to $0.617029 per share (as may be equitable adjusted in the future as a result of any stock split, stock dividend, recapitalization and the like). The Sellers and Company Optionees will have all rights and remedies under applicable law with respect to Losses resulting from any breaches of representations and warranties made by Optium in Article V of this Agreement, subject to the survival periods of such representations and warranties. Payment of any amount to which Optium is entitled from a Seller (in its capacity as a Seller) under this Section 10.06 shall be made only by the delivery of Optium Stock. 10.07. NO WAIVER. No waiver of a closing condition by Optium or Sellers shall limit its or their rights under Section 10.02. 10.08. LIMITATIONS OF LIABILITY AND OBLIGATIONS OF CERTAIN SELLERS. (a) DEUTSCHE.

A liability arising under or in connection with this Agreement is limited to, and can be enforced against Deutsche only to, the extent to which it can be satisfied out of the assets of the Deutsche Trust out of which Deutsche is actually indemnified for the liability. This limitation of Deutsche's liability applies despite any other provision of this Agreement and extends to all liabilities and obligations of Deutsche in any way connected with any representation, warranty, conduct, omission, agreement or transaction related to this Agreement. (ii) No party may sue Deutsche in any capacity other than as responsible entity of the Deutsche Trust, including seeking the appointment of a receiver (except in relation to property of the Deutsche Trust), a liquidator, an administrator, or any similar person to Deutsche or prove in any liquidation, administration or arrangement of or affecting Deutsche (except in relation to property of the Deutsche Trust). (iii) The provisions of this clause 10.08 do not apply to any obligation or liability of Deutsche to the extent that it is not satisfied because under the deed governing the Deutsche Trust or by operation of law there is a reduction in the extent of Deutsche's indemnification out of the assets of the Deutsche Trust, as a result of Deutsche's fraud, negligence or breach of trust. 53 (iv) No attorney, agent, receiver or receiver and manager appointed in accordance with this agreement has authority to act on behalf of Deutsche in a way which exposes Deutsche to any personal liability, and no act or omission of any such person will be considered fraud, negligence or breach of trust of Deutsche for the purpose of clause 10.08(a)(iii). (v) Notwithstanding any other provision of this agreement, Deutsche: (A) is a funds management company which is part of Deutsche Bank AG (the "DEUTSCHE GROUP"); (B) is the responsible entity and manager of a number of managed funds and trusts and has obligations and duties in relation to each of those managed funds and trusts that are similar to its obligations and duties in relation to the Deutsche Trust; (C) may, and other entities in the Deutsche Group may, invest funds in companies or other entities that may compete with Optium or the Company; and (D) cannot foster and promote the business of Optium or the Company where such conduct would breach its obligations to, or adversely impact on, the shareholding of Deutsche or other entities in the Deutsche Group in any such competing company or entity in which funds managed by Deutsche have been invested. (vi) Deutsche warrants that, in respect of the Deutsche Trust, as at the date of this Agreement: (A) it is the only responsible entity of the Deutsche Trust; (B) no action is proposed to remove it as responsible entity of the Deutsche Trust; (C) there is no default under the terms of the constitution of the Deutsche Trust; and (D) it has the power to enter into and perform this Agreement; and (E) Deutsche as responsible entity, has a right of indemnity out of the trust assets of the Deutsche Trust for all liabilities incurred by it under this Agreement in accordance with the terms of the trust.

A liability arising under or in connection with this agreement is limited to and can be enforced against TVP in its capacity as trustee of the TVP No. 3 Fund only to the extent that it can be satisfied out of the property of the TVP No. 3 Fund out of which TVP is actually indemnified for the liability.

(ii) The parties hereto other than TVP may not sue TVP in any capacity other than as trustee of the TVP No. 3 Fund or seek the appointment of a receiver (except in relation to property of the TVP No. 3 Fund), a liquidator, an administrator, or any similar person to TVP or prove in any liquidation, administration or arrangement of or affecting TVP (except in relation to property of the TVP No. 3 Fund). (iii) The provisions of this clause 10.08 do not apply to any obligation or liability of TVP to the extent that it is not satisfied because under the trust deed of the TVP No. 3 Fund or by operation of law there is a reduction in or limitation on the extent of TVP's indemnification out of the assets of the TVP No. 3 Fund, as a result of TVP's fraud, negligence or breach of trust.
