Parent, Buyer and Seller are each referred to herein as an “Interested Party” and are collectively referred to herein as the “Interested Parties.”

A. Parent, Buyer, Seller and the persons listed on Schedule A to the Asset Purchase Agreement have entered into an Asset Purchase Agreement dated as of April 1, 2005 (as the same may be amended, the “Asset Purchase Agreement” capitalized terms used herein without definition shall have the meaning assigned thereto in the Asset Purchase Agreement) setting forth certain terms and conditions pursuant to which Buyer shall acquire substantially all of the assets of the Business from Seller.

B. Pursuant to Section 2.6 of the Asset Purchase Agreement, a portion of the Purchase Price is to be held in escrow by the Escrow Agent in accordance with the terms and conditions set forth therein and herein to secure certain indemnification obligations of Seller to Buyer and Parent under Article 12 of the Asset Purchase Agreement and/or to be subject to the attainment of the Earn-out Milestones set forth in the Asset Purchase Agreement.

NOW THEREFORE, in consideration of the foregoing and for the mutual covenants and agreements contained herein, and for other good and valuable consideration, the parties hereto agree as follows:

1. ESTABLISHMENT OF ESCROW FUND

1.1 Deposit of Cash and Shares.

(a) Parent agrees that within twenty days after the Closing Date it shall deliver in escrow to the Escrow Agent on Buyer’s behalf: (i) 129,096 shares of Parent’s Common Stock, which shares shall be evidenced by certificates registered in the name of Seller as set forth on Exhibit 1.1-A hereto (such shares, together with any additional shares issued to the registered holders thereof in accordance with Section 1.2 of this Agreement, the “Subject Purchase Shares”); (ii) 70,460 shares of Parent’s Common Stock, which shares shall be evidenced by those certificates registered in the name of Seller set forth on Exhibit 1.1-B hereto (such shares, together with any additional shares issued to the registered holders thereof in accordance with Section 1.2 of this Agreement, the “Subject Earnout Shares”, and together with the Subject Purchase Shares, the

“Subject Shares”); and (iii) 136,776 shares of Parent’s Common Stock, which shares shall be evidenced by those certificates registered in the name of Seller set forth on Exhibit 1.1-C hereto (such shares, together with any additional shares issued to the registered holders thereof in accordance with Section 1.2 of this Agreement, the “Immune Earnout Shares”, and together the Subject Shares, the “Escrow Shares”).

(b) Parent agrees that on the Closing Date it shall deliver in escrow to the Escrow Agent on Buyer’s behalf by wire transfer to the account of the Escrow Agent set forth on Schedule 1 hereto $1,885,318 in immediately available funds (such funds, the “Escrow Cash”, and together with the Subject Shares, the “Subject Funds” and the Escrow Cash and Escrow Shares, together, the “Escrow Fund”).

(d) Seller agrees that on the Closing Date it shall deliver in escrow to the Escrow Agent six stock powers executed in blank bearing signature guarantees. The Escrow Agent shall at any time be entitled to request in writing from Seller additional stock powers executed in blank bearing signature guarantees. If the Escrow Agent is not in timely receipt of the aforementioned stock powers to be delivered on the Closing Date, or any stock powers requested by the Escrow Agent thereafter, then Seller shall indemnify and hold the Escrow Agent harmless as to any liability incurred by it by reason of its not having received the necessary stock powers in order to carry out its duties and obligations under this Agreement, and to reimburse the Escrow Agent for all of its cost or expenses, including, among other things, counsel fees and expenses reasonably incurred by reason of its duties hereunder.

1.2 Dividends, Distributions and Rights of Ownership of Escrow Shares.

(a) So long as the Escrow Shares are held in escrow, any and all shares of Parent’s capital stock resulting from any share dividend, reclassification, stock split, subdivision or combination of shares, recapitalization, merger or other events made with respect to the Escrow Shares shall be delivered to the Escrow Agent, registered in the name of Seller and such shares shall constitute Subject Purchase Shares, Subject Escrow Shares or Immune Escrow Shares, as applicable.

(b) So long as the Escrow Shares are held in escrow, each registered holder thereof shall have the right to vote its respective Escrow Shares and be able to exercise all other incidents of ownership of such Escrow Shares, not inconsistent with the terms and conditions of this Agreement, and any and all cash dividends, dividends payable in property or other distributions of any kind (except for the shares contemplated in Section 1.2(a)) made in respect of such Escrow Shares shall be distributed on the distribution date pertaining thereto by Parent to the registered holder thereof, and Parent and the Escrow Agent (but only as directed in writing by Parent)

- 2 -

agree to take all reasonable steps necessary to allow the exercise of such rights by the registered holder thereof.

1.3 No Encumbrance. None of the Escrow Funds or any beneficial interest therein may be pledged, sold, assigned or transferred, including by operation of law, or may be taken or reached by any legal or equitable process in satisfaction of any debt or other liability of any party hereto prior to the release thereof from escrow in accordance with Section 3.

1.4 Power to Transfer Escrow Cash and Escrow Shares. The Escrow Agent is hereby granted the power to effect any transfer of the Escrow Cash or Escrow Shares in accordance with the terms and provisions of this Agreement.

1.5 Investment of Escrow Cash. The Escrow Agent shall maintain the Escrow Cash in one or more interest-bearing accounts. During the term of this Agreement, the Escrow Cash shall be invested and reinvested by the Escrow Agent, in one or more of the investments set forth on Exhibit 1.5 to the extent permitted by law and as directed in writing by Seller. The Escrow Agent shall have the right to liquidate any such investments in order to provide funds necessary to make required payments under this Agreement. Neither the Escrow Agent, Parent nor Buyer shall have any liability for any loss sustained as a result of any investment made pursuant to the written direction of Seller or as a result of any liquidation of any such investment prior to its maturity, or for the failure of Seller to give the Escrow Agent written directions to invest or reinvest the Escrow Cash. All interest and other income earned by the investment, reinvestment and/or deposit of the Escrow Cash in accordance with this Section 1.5 shall be released from the Escrow Fund and delivered to Seller or as otherwise directed by Seller no later than thirty (30) days after the release of all Escrow Funds.

1.7 Taxation. The Escrow Agent shall act as agent to Seller and will make all appropriate tax filings and withhold all required amounts from distributions thereto. All amounts earned in the Escrow Fund shall be taxed in the hands of Seller. Seller hereby agrees to provide the Escrow Agent with its certified tax identification number by signing and returning a Form W-9 (or a Form W-8 BEN, in case of non-U.S. persons) to the Escrow Agent upon execution and delivery of this Agreement. Seller understands that, in the event its tax identification number is not certified to the Escrow Agent, the Internal Revenue Code, as amended from time to time, may require withholding of a portion of any interest or other income earned on the investment of the Escrow Cash. Seller agrees (i) to assume any and all obligations now or hereafter imposed upon it by any applicable tax law with respect to any payment from or distribution of the Escrow Fund or performance of other activities under this Agreement,

- 3 -

and to instruct the Escrow Agent in writing with respect to the Escrow Agent’s responsibility for withholding and other taxes, assessments or other governmental charges applicable to it, (ii) to instruct the Escrow Agent with respect to any certifications and governmental reporting that may be required under any laws or regulations that may be applicable to it as a result of this Agreement, and (iii) to indemnify and hold the Escrow Agent harmless from any liability or obligation on account of taxes, assessments, additions for late payment, interest, penalties, expenses and other governmental charges that may be assessed or asserted against the Escrow Agent, on its account, on account of or relating to the Escrow Fund, the management established hereby, any payment from or distribution of the Escrow Fund pursuant to the terms hereof or other activities performed hereunder, including without limitation any liability for the withholding or deduction of (or the failure to withhold or deduct) the same, and any liability for failure to obtain proper certifications or to report properly to governmental authorities in connection with this Agreement, including costs and expenses (including reasonable legal fees and expenses), interest and penalties. The foregoing indemnification and agreement to hold harmless shall survive the termination of this Agreement.

2. RESOLUTION OF CLAIMS

2.1 Indemnification Obligations.

(a) Seller acknowledges and agrees that the Subject Funds may, subject to the terms and provisions of this Agreement, serve as a source, but not the sole source, of payment for the indemnity obligations under Article 12 of the Asset Purchase Agreement, including any Claim (as hereinafter defined) resolved pursuant to Section 2.3. Notwithstanding the foregoing, pursuant to Section 12.6 of the Asset Purchase Agreement, Parent’s and Buyer’s claims for indemnification pursuant to Sections 12.2(a)(i) and 12.2(a)(vii) of the Asset Purchase Agreement shall be satisfied solely by the Subject Funds. Payment for any amount determined to be owing to Parent or Buyer under such indemnity obligations (“Damages”) and, without duplication, any award of attorneys’ fees and charges owing to Parent or Buyer pursuant to Section 2.3(c)(iii) of this Agreement (a “Prevailing Party Award”) may, subject to the terms and provisions of Sections 2.1(b), 2.2 and 2.3, be made by the release from escrow and delivery to Parent or Buyer, as the case may be (each such payment, an “Escrow Adjustment”), of Subject Funds equal to the sum of Damages plus any Prevailing Party Award.

(b) Notwithstanding any provision of this Agreement to the contrary, the Subject Earnout Shares shall serve solely as a source for payment for indemnification Claims made by Parent or Buyer pursuant to Section 12.2(a)(iii) of the Asset Purchase Agreement as a result of Seller’s failure to pay any required state sales Taxes in any applicable jurisdiction. To the extent there shall be an Escrow Adjustment with respect to any such Claim, such Escrow Adjustment shall be paid first from the Subject Earnout Shares (valued at the closing price of Parent common stock on the day prior to release) and only upon exhaustion of such funds shall Subject Purchase Shares or Escrow Cash be available for such indemnity; provided, however, that if one or more

- 4 -

Escrow Adjustments are made against the Subject Earnout Shares and it is later determined that the Earnout Milestones were not met, Parent and Buyer shall have the right to obtain the Escrow Adjustment(s) contemplated by this paragraph from the Subject Purchase Shares and Escrow Cash or against the Seller or the Covenantors directly as set forth in Section 12.6 of the Asset Purchase Agreement.

2.2 Notice of Claims. Parent or Buyer, as the case may be (such notifying party, the “Claimant”), shall give Seller written notice of any claim, damage, or legal action or proceeding giving rise to indemnification rights under the Asset Purchase Agreement (a “Claim”) and the amount thereof and shall provide a copy of such notice to the Escrow Agent. Each notice of a Claim for which Claimant seeks an Escrow Adjustment hereunder (a “Notice of Claim”) shall be delivered on or before the Second Release Date (as defined in Section 3.1(b)). Each Claim shall be deemed to be a Contested Claim unless it becomes an Uncontested Claim pursuant to Section 2.3.

2.3 Resolution of Claims. Each Notice of Claim shall be resolved as follows:

(a) Uncontested Claims. In the event that Seller does not contest a Notice of Claim (an “Uncontested Claim”) in writing within thirty (30) days after such Notice of Claim was given thereto, the Claimant may deliver to the Escrow Agent, with a copy to Seller, a written demand (a “Demand”) stating that such Notice of Claim has been given in accordance with this Agreement and that no notice of contest has been received from Seller during the period specified herein and further setting forth the amount of the proposed Escrow Adjustment (which shall not exceed the amount of the Claim set forth in the Notice of Claim) to be made in accordance with this Section 2.3(a). Any such Escrow Adjustment shall be distributed to Parent. If Seller does not contest the Claim within the thirty (30) day period set forth above its right to object to such Claim shall expire.

(b) Contested Claims. If Seller gives written notice to the Claimant and the Escrow Agent contesting all or a portion of any Notice of Claim (a “Contested Claim”) within thirty (30) days following the date upon which said Notice of Claim was given to Seller, then (i) if the applicable Claim arose as the result of one or more third party claims against Claimant in a litigation or arbitration, then such Claim (and any resulting Escrow Adjustment) shall await the final decision, award or settlement of such litigation or arbitration and, if liability to Parent and/or Buyer for any such third party claim is disputed by Seller, until the resolution of any such Arbitrable Claim in accordance with Section 2.3(c), and (ii) if the applicable Claim arose directly between Parent or Buyer on the one hand and Seller or Covenantors on the other hand, including any disputes regarding performance or nonperformance of a party’s obligations under this Agreement, or if liability for any third party claim is disputed by Seller or Covenantors (“Arbitrable Claims”), then such Claim (and any resulting Escrow Adjustment) shall be settled in accordance with Section 2.3(c), provided, any portion of such Claim that is not contested or is subsequently settled by Claimant and Seller or Covenantors, as applicable, shall be deemed to constitute an Uncontested Claim.

- 5 -

(i) Arbitration Rules. Any Arbitrable Claim, and any dispute between any of the Interest Parties under this Agreement, shall be submitted to final and binding arbitration as provided in Section 12.8 of the Asset Purchase Agreement. In the event that the Escrow Agent institutes an action for interpleader in accordance with Section 4.5 as a result of a dispute between the parties, the parties hereby agree to jointly seek to stay such interpleader action pending the resolution of any arbitration commenced by the parties or any dispute pursuant to Section 2.3(b).

(ii) Binding Effect. The final decision of the arbitrator shall be furnished in writing to the Escrow Agent, and the Interested Parties and will constitute a conclusive determination of the issue in question, binding upon Seller and the Interested Parties. The arbitrator shall have the authority to grant any equitable and legal remedies that would be available in any judicial proceeding instituted to resolve an Arbitrable Claim. If the award or decision of the arbitrator concludes that Escrow Cash and Subject Shares are to be released in favor of any Claimant either in satisfaction of Damages or as Prevailing Party Awards, the arbitrator shall specify the amount of Escrow Cash and number of Subject Shares to be so released either in the arbitrator’s final award or decision or a supplementary report or finding. Any judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction over the subject matter thereof.

(iii) Compensation of Arbitrator. The arbitrators will be compensated for their services as provided in Section 12.8(d) of the Asset Purchase Agreement and any expense allocated by such arbitrators against Seller and/or Covenantors shall be deemed to constitute an Uncontested Claim, and if a Demand is issued with respect thereto, shall be satisfied by an Escrow Adjustment in accordance with Section 3.2(b).

(iv) Terms of Arbitration. No arbitrator chosen in accordance with the terms of this Agreement and the Asset Purchase Agreement shall have the power to alter, amend or otherwise affect the terms and provisions hereof or thereof or any other documents executed in connection herewith or therewith.

(v) Exclusive Remedy. Arbitration or mediation under this Section 2.3(c) shall be the sole and exclusive remedy of the parties for any Arbitrable Claim arising out of this Agreement.

(a) Not more than ten business days after the first anniversary of the Closing Date (the “Initial Release Date”) the Interested Parties shall jointly prepare, execute and deliver written notice to the Escrow Agent (such notice, the “Initial Release Notice”) of the Initial Release Amount (including the calculations upon which

- 6 -

such amount is based) to be released from the remaining Subject Funds, pursuant to Section 3.1(c), on the Initial Release Date. The “Initial Release Amount” shall, subject to the limitations set forth in Section 3.1(c), be an amount equal to (i) $2,500,000, less (ii) the sum of (x) the aggregate amount of Escrow Cash plus the value of Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to release or, if not yet released, valued at the closing price of Parent common stock on the day prior to the preparation of the Initial Release Notice), delivered to or deliverable to Parent in satisfaction of Uncontested Claims or Contested Claims which have been settled by the Interested Parties on or before the date the Initial Release Notice is prepared, and (y) the aggregate amount underlying all other Contested Claims pending on the first anniversary of the Closing Date.

(b) Not more than ten business days after the second anniversary of the Closing Date (the “Second Release Date”) the Interested Parties shall jointly prepare, execute and deliver written notice to the Escrow Agent (such notice, the “Second Release Notice”) of the Second Release Amount (including the calculations upon which such amount is based) to be released from the remaining Subject Funds, pursuant to Section 3.1(c), on the Second Release Date. The “Second Release Amount” shall be an amount equal to:

(i) (x) All of the remaining Escrow Cash and all of the remaining Subject Purchase Shares, less (y) the sum of (A) the aggregate amount of Escrow Cash plus the value of Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to the preparation of the Second Release Notice) deliverable to Parent in satisfaction of Uncontested Claims that have not yet been paid out or Contested Claims that have been settled by the Interested Parties but not paid out before the date the Second Release Notice is prepared; and (B) the aggregate amount underlying all Contested Claims pending on the second anniversary of the Closing Date; and

(ii) if the Earnout Milestones have been achieved as set forth in the Asset Purchase Agreement, the remaining Subject Earnout Shares, less (y) the value of Subject Earnout Shares (valued at the closing price of Parent common stock on the day prior to the preparation of the Second Release Notice) deliverable to Parent in satisfaction of Sales Tax Uncontested Claims (as defined below) or Sales Tax Contested Claims (as defined below) which have been settled by the Interested Parties but not paid out on or before the date the Second Release Notice is prepared; and (z) the aggregate amount underlying all Sales Tax Contested Claims pending on the second anniversary of the Closing Date. For purposes of this Agreement, “Sales Tax Uncontested Claims” and “Sales Tax Contested Claims” shall mean Uncontested Claims and Contested Claims, as the case may be, that relate to indemnification Claims made by Parent or Buyer under Section 12.2(a)(iii) of the Asset Purchase Agreement as result of the failure by Seller to pay state sales Taxes in any applicable jurisdiction.

(c) Provided it has received an Initial Release Notice and a Second Release Notice, as applicable, the Escrow Agent shall, on the Initial Release Date and the Second Release Date, respectively, or if such date is not a business day, on the

- 7 -

next business day thereafter, release from escrow and deliver (by first class mail, registered mail or overnight courier service) to Seller (or as otherwise directed by Seller), Escrow Funds equal to the Initial Release Amount and the Second Release Amount, respectively, which amounts (other than the amounts set forth in Sections 3.1(b)(ii) and 3.1(b)(iii)) shall be comprised of 38% Escrow Cash and 62% Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to release). Notwithstanding the foregoing, the amount of Escrow Cash and the number of Subject Purchase Share to be released to Seller on the Initial Release Date shall be reduced to the extent necessary to maintain in escrow after the Initial Release Date fifty percent (50%) of the Escrow Cash and fifty percent (50%) of the number of Subject Purchase Shares (adjusted for stock splits, stock dividends, recapitalizations and similar events) initially deposited in escrow under this Agreement. No Escrow Funds shall be released by the Escrow Agent on the Initial Release Date or on the Second Release Date if it has not received an Initial Release Notice or Second Release Notice, as the case may be.

(d) If the Earnout Milestones as set forth in the Asset Purchase Agreement have not been achieved on the second anniversary of the Closing Date, the Immune Earnout Shares shall be delivered to Parent on the Second Release Date. If the Earnout Milestones as set forth in the Asset Purchase Agreement have been achieved on the second anniversary of the Closing Date, the Immune Earnout Shares shall be delivered to Seller (or as otherwise directed by Seller) on the Second Release Date. The Escrow Agent shall have no responsibility to determine whether the Earnout Milestones have been met. The Immune Earnout Shares to be released to Seller (in the event the Earnout Milestones are met) or to Parent (in the event that the Earnout Milestones shall not be met) shall be determined jointly by Seller and Parent and set forth in a written notice signed by both parties and delivered to the Escrow Agent. The inability of Seller and Parent to agree on, prepare, sign and deliver such written notice shall be an Arbitrable Claim that is subject to resolution pursuant to Section 2.3(c) of this Agreement.

(e) The inability of the Interested Parties to agree on and jointly prepare, execute and deliver the Initial Release Notice and/or the Second Release Notice shall also be an Arbitrable Claim that is subject to resolution pursuant to Section 2.3(c) of this Agreement.

(i) in the case of (i) or (ii) above, the Escrow Agent shall, within ten (10) calendar days of receipt of the settlement agreement or the Claimant Distribution Notice, as applicable, (a) release to Parent the Subject Funds specified in the Escrow Adjustment, which amount shall be either (i) comprised of 38% Escrow Cash and 62% Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to release) or (ii) paid out of the Subject Earnout Shares (valued at the closing price of Parent common stock on the day prior to release), as the case may be, and (b) if the Second Release Date has occurred, and there are no remaining Contested Claims, release the remaining Subject Funds, less the amount of any Uncontested Claims remaining unpaid, from escrow and deliver (by first class mail, registered mail or overnight courier service) the same to Seller (or as otherwise directed by Seller); or

(ii) in the case of (iii) above, unless the First Release Date has not occurred or there are other unpaid Uncontested Claims or other Contested Claims requiring that the amounts continue to be retained, the Escrow Agent shall, within ten (10) calendar days of receipt of the Seller Distribution Notice, release from escrow and deliver (by first class mail, registered mail or overnight courier service) to Seller (or as otherwise directed by Seller), remaining Subject Funds equal to the amount, if any, of Contested Claims which were withheld from the Initial Release Amount or Second Release Amount, as the case may be, which amount shall either be (i) comprised of 38% Escrow Cash and 62% Subject Shares (valued at the closing price of Parent common stock on the day prior to release) or (ii) paid out of the Subject Earnout Shares (valued at the closing price of Parent common stock on the day prior to release), as the case may be; provided, however, that prior to the Second Release Date, no more than the following is eligible for release: $2,500,000, less the sum of (w) the aggregate amount of Escrow Cash plus the value of Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to release) previously released to Seller (or as otherwise directed by Seller) (and never subject to a Claim), (x) the aggregate

- 9 -

amount of Escrow Cash plus the value of Subject Purchase Shares (valued at the closing price of Parent common stock on the day prior to release or, if not yet released, valued at the closing price of Parent common stock on the day prior to the date of any proposed release to Seller pursuant to such Seller Distribution Notice) delivered to or deliverable to Parent in satisfaction of Uncontested Claims or Contested Claims which have been settled by the Interested Parties on or before the date the Initial Release Notice was prepared, and (y) the aggregate amount underlying all other Contested Claims pending on the first anniversary of the Closing Date; provided, further, however, that prior to the Second Release Date the amount of Escrow Cash and the number of Subject Purchase Share to be released to Seller pursuant to the foregoing shall be reduced to the extent necessary to maintain in escrow fifty percent (50%) of the Escrow Cash and fifty percent (50%) of the number of Subject Purchase Shares (adjusted for stock splits, stock dividends, recapitalizations and similar events) initially deposited in escrow under this Agreement.

3.3 Fractional Escrow Shares; Reallocations. Notwithstanding any provision of this Agreement to the contrary, in lieu of releasing any fractional Escrow Shares, any fraction of a released Escrow Share that would otherwise be released shall be rounded down to the nearest whole Escrow Share. In the event any release of Subject Escrow Funds is to be comprised of 38% Escrow Cash and 62% Subject Purchase Shares (or other proportion) pursuant to the terms of this Agreement and there is insufficient Escrow Cash or Subject Purchase Shares to make such an allocation in such proportion, then Escrow Cash or Subject Purchase Shares, as the case may be, shall be released in lieu thereof to satisfy such deficiency.

In the event the Escrow Agent shall resign or shall be removed pursuant to Section 7.1.1, a successor Escrow Agent shall be appointed by the Interested Parties as evidenced by a written notice signed by Parent and Seller and filed with the existing Escrow Agent. If the Interested Parties are unable to agree upon a successor or shall have failed to appoint a successor prior to the expiration of thirty (30) days following the date of the notice of resignation or removal, then the acting Escrow Agent, at the expense of the Interested Parties, may petition any court of competent jurisdiction for the appointment of a successor Escrow Agent or other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto. Each successor Escrow Agent shall execute, acknowledge and deliver to its predecessor, and also to the Interested Parties, an instrument in writing accepting such appointment hereunder, whereupon, subject to Section 7.1.1, the predecessor Escrow Agent shall deliver the balance of the Escrow Fund then its possession to such successor which shall immediately, without any further act, become Escrow Agent hereunder, fully vested with all the duties, responsibilities and obligations of its predecessor; but such predecessor shall, nevertheless, on the written request of its successor or any of the parties hereto, execute and deliver an instrument or instruments transferring to such successor all the rights of such predecessor hereunder, and shall duly assign, transfer and deliver all property, securities and monies held by it pursuant to this Agreement to its successor. Should any instrument be required by any successor for more fully vesting in such successor the duties, responsibilities, and obligations hereby vested or intended to be vested in the predecessor, any and all such instruments in writing shall, on the request of any of the other parties hereto, be executed, acknowledged, and delivered by the predecessor.

7.4 Release. Upon acknowledgment by any successor Escrow Agent of the receipt of the then remaining balance of the Escrow Fund, the then acting Escrow Agent shall be fully released and relieved of all duties, responsibilities and obligations under this Agreement that may arise and accrue thereafter.

7.5 Successors. Any corporation or association into which the Escrow Agent in its individual capacity may be merged or converted or with which it may be

- 13 -

consolidated, or any corporation or association resulting from any merger, conversion or consolidation to which the Escrow Agent in its individual capacity shall be a party, or any corporation or association to which all or substantially all the corporate trust business of the Escrow Agent in its individual capacity may be sold or otherwise transferred, shall be the Escrow Agent hereunder without further act.

8. FEE

The Escrow Agent will be paid one-half by Parent and one-half by Seller for all billed services and expenses hereunder in accordance with the Fee Schedule attached hereto as Exhibit A. In the event that the Escrow Agent is made a party to litigation with respect to the property held hereunder, or brings an action in interpleader, or in the event that the conditions to this Agreement are not promptly fulfilled, or the Escrow Agent is required to render any service not provided for in this Agreement and fee schedule, or there is any assignment of the interests of this Agreement or any modification hereof, the Escrow Agent shall be entitled to reasonable compensation, one-half from Parent and one-half from Seller, for such extraordinary services and reimbursement for all fees, costs, liability, and expenses, including attorneys fees and expenses.

9. TERMINATION; DEFICIENCY CLAIMS

This Agreement and the escrow created hereby shall terminate following Escrow Agent’s delivery, and Parent’s and Buyer’s release of all remaining Escrow Cash and Escrow Shares pursuant to Section 2 or 3 of this Agreement. In the event that the value of the Escrow Cash and Subject Shares released to Parent pursuant to the provisions of this Agreement is insufficient to pay in full to Parent the total amount of the Damages and Prevailing Party Awards to which it and Buyer is entitled, Parent and Buyer shall be entitled to pursue its remedies for any such deficiency to the extent permitted pursuant to Section 12.6 of the Asset Purchase Agreement; provided, that no party hereto in connection with any such action may contest any Uncontested Claim or any Contested Claim that has been resolved in accordance with the provisions of this Agreement. Notwithstanding the foregoing sentence, pursuant to Section 12.6 of the Asset Purchase Agreement, Parent’s and Buyer’s claims for indemnification pursuant to Sections 12.2(a)(i) and 12.2(a)(vii) of the Asset Purchase Agreement shall be satisfied solely by the Subject Funds, and Parent and Buyer will not be entitled to pursue remedies for any deficiency for any such claims that are not satisfied by the Subject Funds.
