(b) Buyer and SeraCare agree to allocate the Purchase Price in accordance with the rules under Section 1060 of the Internal Revenue Code of 1986, as amended (the “Code”) and the Treasury Regulations promulgated thereunder. Such Purchase Price allocation shall be set forth in Schedule 2.1. Buyer and SeraCare recognize that the Purchase Price does not include Buyer’s acquisition expenses and that Buyer will allocate such expenses appropriately. SeraCare and Buyer agree to act in accordance with the computations and allocations contained in Schedule 2.1 (including any modifications thereto reflecting any post-closing adjustments) in any relevant Tax returns or filings, including any forms or reports required to be filed pursuant to Section 1060 of the Code, the Treasury Regulations promulgated thereunder or any provisions of local, state and foreign law (“1060 Forms”), and to cooperate in the preparation of any 1060 Forms and to file such 1060 Forms in the manner required by applicable law.

2.2. Payment of Purchase Price. Except as otherwise set forth in this Section 2.2 or as provided in Section 2.3, the Purchase Price shall be payable by a wire transfer of immediately available federal funds to such bank accounts as shall be designated by SeraCare prior to Closing.

(a) Payment of Initial Amount. Buyer shall pay SeraCare a sum of two million United States Dollars ($2,000,000) (the “Initial Amount”) immediately upon the Closing, subject to any necessary adjustments as set forth in Section 2.3 hereof.

(b) Payment of Royalty Amounts. Buyer shall pay SeraCare royalty amounts of 7.5% of all Net Sales (as defined below) for the initial twelve (12) month period beginning on the Closing Date (the “First Royalty Amount”) and for each of the next sixteen (16) three (3) month periods thereafter (each, a “Royalty Amount” and together, the “Royalty Amounts”). Buyer shall pay the First Royalty Amount to SeraCare within sixty (60) days of the conclusion of the initial twelve (12) month period. Buyer shall pay all subsequent Royalty Amounts to SeraCare within thirty (30) days of the conclusion of each applicable three (3) month period.

(i) Net Sales. The First Royalty Amount and each succeeding Royalty Amount shall be 7.5% of (A) the sum of the gross revenues from the sale or license by Buyer of the Assets acquired herein, (B) minus reasonable reductions relating to normal and customary trade and quantity discounts, allowances and rebates, returns and replacements, warranty costs, special handling or shipping, samples, taxes and duties to the extent the foregoing are actually paid or accrued on the books and records of Buyer in accordance with GAAP (“Net Sales”). For the avoidance of doubt, reductions in gross revenues set forth in clause (B) of the foregoing sentence shall not, without the prior written consent of SeraCare (which consent shall not be unreasonably withheld), include any expense not substantially related to or required for Buyer’s operation of the Business after the Closing Date.

(ii) Written Report. Within sixty (60) days following the end of the initial twelve (12) month period for which the First Royalty Amount is due and payable, and within thirty (30) days following the end of each of the three (3) month periods for which a Royalty Amount is due and payable thereafter, Buyer shall calculate the Net Sales for each such period and shall deliver to SeraCare (A) a written report setting forth in reasonable detail the amount of Net Sales for each such period and (B) documentation reasonably appropriate to support the calculation of Net Sales for each such period (each written report and accompanying documentation, a “Written Report”). Each Written Report shall be accompanied by a certificate signed by the chief financial officer of Buyer stating that information on such Written Report has been derived from the books and records of the Buyer in conformity with GAAP, and that such information is complete and accurate in all material respects.

(iii) Limited Right of Offset. The payment of the First Royalty Amount shall be subject to a limited right of offset based on any Buyer Losses (as defined in Section 8.1(a)) as follows: Buyer may deduct, from the amount due and payable to SeraCare under the First Royalty Payment, for any Buyer Losses resulting from SeraCare’s indemnification of Buyer for breaches of certain of the representations and warranties contained in this Agreement as set forth in Section 8.1(a) hereof, or for any Buyer Losses resulting from SeraCare’s indemnification of Buyer against the Excluded Liabilities as set forth in Section 8.1(a) hereof; provided, however, that any such right of offset exercisable by the Buyer as a result of Buyer Losses pursuant hereto shall terminate immediately upon the calculation and payment of the First Royalty Amount (if any); and provided further, that such right of offset shall be subject to the Seller Threshold described in Section 8.1(b)(ii) hereof, and in any event, the Buyer’s right of offset shall be subject to an aggregate limit of the total amount of the First Royalty Amount due and payable to SeraCare under this Section 2.2(c).

(iv) Resolution of Disputes. SeraCare, together with such legal, financial, or other counsel as it may deem appropriate, shall, from time to time, upon reasonable

prior written notice to Buyer, be given reasonable access to the sales and accounting records of Buyer for the purpose of verifying Net Sales for the initial twelve (12) month period and any of the subsequent three (3) month periods referred to in this Section 2.2(c). If SeraCare disagrees with any Written Report delivered to SeraCare pursuant to Section 2.2(c)(ii) or with the corresponding amount of the First Royalty Amount and any succeeding Royalty Amount due and payable to SeraCare pursuant to this Section 2.2(c), then, within thirty (30) days after the receipt by SeraCare of the applicable Written Report, (such 30-day period to be automatically tolled by reason of Buyer’s failure to make reasonably sufficient books and records timely available to SeraCare in accordance with this Section 2.2(c)(iv)), SeraCare shall notify Buyer in writing of its objections to the Written Report. If SeraCare has not notified Buyer of an objection within such thirty (30) day period, the applicable Written Report shall be deemed final and conclusive. Otherwise, SeraCare and Buyer shall review the Written Report and negotiate in good faith to resolve any discrepancies in accordance with Section 10 hereof.

(v) Operation of the Business. During the initial twelve (12) month period and during each of the subsequent sixteen (16) three (3) month periods in which the First Royalty Amount and any subsequent Royalty Amounts may be due and payable to SeraCare, Buyer shall operate the Business in good faith and shall not take any actions the primary purpose of which is to lower any potential Royalty Amounts.

(a) Calculation of the Closing Inventory Adjustments. The Purchase Price shall be decreased on a dollar-for-dollar basis by the amount (if any) by which the gross book value of SeraCare’s Human Sample Inventory as of the Closing (the “Closing Inventory”) is less than 90% of the gross book value of the Human Sample Inventory as of September 30, 2006 set forth on Schedule 1.2(c) (the “September Inventory”), as such Closing Inventory is finally determined, accepted, deemed accepted or agreed pursuant to this Section 2.3.

(b) Estimated Closing Inventory. Within the five (5) business days prior to the Closing Date, SeraCare shall deliver a certificate, signed by either the Chief Executive Officer or the Chief Financial Officer of SeraCare, setting forth SeraCare’s good faith estimate of the amount of the Human Sample Inventory of the Business at Closing (the “Estimated Closing Inventory”), which Estimated Closing Inventory shall be binding on the parties hereto except as set forth below.

(c) Purchase Price Adjustment. In the event the gross book value of the Estimated Closing Inventory is less than 90% of the gross book value of the September Inventory set forth on Schedule 1.2(c), Buyer shall deduct, on a dollar-for-dollar basis, the amount by which the gross book value of the Estimated Closing Inventory is less than 90% of the gross book value of the September Inventory set forth on Schedule 1.2(c) from the Purchase Price.

(d) Closing Calculation. Within thirty (30) days after the Closing, Buyer shall utilize a sampling process to verify the approximate amount of the Closing Inventory of the Business, and shall provide SeraCare with evidence of such calculation (as later verified or adjusted, the “Closing Calculation”). In the event that the Closing Calculation shows that the

gross book value of the Closing Inventory is less than 90% of the gross book value of the September Inventory, SeraCare shall pay Buyer, on a dollar-for-dollar basis, for the amount of any such discrepancy. Any payments pursuant to this Section 2.3(d) shall be considered adjustments to the Purchase Price for all purposes. Payment of any adjustment to the Purchase Price pursuant to this Section 2.3(d) shall be made by wire transfer to an account designated by Buyer, in United States Dollars, in immediately available federal funds within three (3) business days after the Closing Calculation has been determined.

(e) Verification of Closing Calculation. For a period of thirty (30) days after Buyer provides SeraCare with the proposed Closing Calculation, SeraCare shall be entitled to full access to the relevant records and working papers prepared by or for Buyer during Buyer’s sampling process to aid in SeraCare’s review of the Closing Calculation. To the extent that SeraCare believes the Closing Calculation has not been properly calculated, it shall, within thirty (30) days after receipt of the Closing Calculation, give written notice (“SeraCare’s Objection”) to Buyer, setting forth the basis of SeraCare’s Objection in reasonable detail and, to the extent practicable, the adjustments to the Closing Calculation which SeraCare believes should be made. Failure to so notify Buyer shall constitute acceptance and approval of the Closing Calculation. If Buyer agrees that any change proposed by SeraCare is appropriate, the change shall be made to the Closing Calculation. If the proposed change is disputed by Buyer, then SeraCare and Buyer shall negotiate in good faith to resolve such dispute in accordance with Section 10 hereof.

(f) Proration of Personal Property Taxes. Personal property Taxes and assessments on the Assets for any taxable period commencing prior to the Closing Date and ending after the Closing Date shall be prorated on a per diem basis between Buyer and SeraCare as of the Closing Date; provided, however, that SeraCare shall not be responsible for any increased assessments on personal property resulting from the transactions contemplated hereby. All such prorations shall be allocated so that items relating to time periods ending on or prior to the Closing Date shall be allocated to SeraCare and items relating to time periods beginning after the Closing Date shall be allocated to Buyer. The amount of all such prorations shall be settled and paid on the Closing Date, provided that final payments with respect to prorations that are not able to be calculated as of the Closing Date shall be calculated and paid as soon as practicable thereafter.

2.4. Sale Order. On February 23, 2007, the Bankruptcy Court entered the Sale Order, attached hereto as Exhibit A, approving the sale of the Business for no less than $2,000,000 plus the Royalty Amounts (as defined below) and on substantially the same terms set forth in the draft Agreement that was attached to the Sale Order. The Sale Order (a) provides for a sale of the Assets free and clear of any and all liens, claims, encumbrances and interests, except Permitted Liens, and (b) authorizes the assumption by SeraCare and the assignment to Buyer, effective upon the Closing, of the Equipment Leases and Contracts (the “Assumed Agreements”) set forth on Schedule 2.4 and set forth in a pleading submitted to the Bankruptcy Court on the following terms and conditions:

Such Schedule 2.4 and such exhibit shall set forth the amounts necessary to cure defaults under each of such Assumed Agreements as determined by SeraCare based on SeraCare’s books and records.

(ii) If there exists on the Closing Date any default related to an Assumed Agreement, SeraCare shall be responsible for any amounts to be cured pursuant to Section 365(a) of the Bankruptcy Code as a condition to the assumption and assignment of such Assumed Agreement. At or prior to the Closing Date, SeraCare shall pay all cure amounts for the Assumed Agreements, and Buyer shall cooperate with SeraCare in providing to the Bankruptcy Court any evidence necessary to prove adequate assurance of future performance necessary to effect the assumption and assignment of the Assumed Agreements.

(iii) Buyer shall be responsible for all costs and expenses incurred after the Closing Date that are necessary in connection with providing adequate assurance of future performance with respect to the Assumed Agreements.

Notwithstanding anything to the contrary herein, SeraCare shall have the unconditional right to terminate or reject in the Bankruptcy Court any Equipment Leases or Contracts not assumed by Buyer as Assumed Agreements pursuant to this Section 2.4.

communicate directly with customers of the Business or have access to customer lists principally related to the Business (or other customer-specific information) prior to Closing unless and until Buyer executes a non-solicitation agreement in a form mutually satisfactory to SeraCare and Buyer. Buyer and its representatives will hold in confidence all confidential information obtained from SeraCare, its officers, agents, representatives, employees or customers, as the case may be, in accordance with the provisions of the Non-disclosure Agreement, dated as of May 25, 2006, between Buyer and SeraCare, as amended and currently in effect (the “Confidentiality Letter”).

(a) Subject to the terms and conditions hereof, SeraCare and Buyer agree to use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement, including all of the following (i) obtain prior to Closing all licenses, certificates, permits, approvals, authorizations, qualifications and orders of governmental authorities as are necessary for the consummation of the transactions contemplated hereby, including but not limited to such consents and approvals as may be required by the Bankruptcy Court; (ii) negotiate in good faith to attempt to reestablish and assign the distribution Contract between GE Healthcare and SeraCare to provide for ongoing Human Sample Inventory distribution for the mutual benefit of Buyer and SeraCare, and (iii) effect any necessary registrations or filings.

Subject to the provisions of Section 10 hereof, SeraCare and Buyer shall not take any action inconsistent with their obligations under this Agreement or which would materially hinder or delay the consummation of the transactions contemplated by this Agreement.

5.4. Public Disclosures. Prior to the Closing Date, no party to this Agreement will issue any press release or make any other public disclosures concerning this transaction or the contents of this Agreement without the prior written consent of the other party. Notwithstanding the above, nothing in this Section 5.4 will preclude any party from making any disclosures required by law or regulation or necessary or desirable in conjunction with the filing of any tax return or other document required to be filed with any federal, state or local governmental body, authority or agency, including any filings deemed necessary or advisable under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the

“Exchange Act”), any disclosures to auditors, or any disclosures necessary or desirable in conjunction with any Bankruptcy Court process or proceeding, including, without limitation, filings or disclosures to creditors.

(a) The parties shall retain the books, records, documents, instruments, accounts, correspondence, writings, evidences of title and other papers relating to the Business and the Assets in their possession (the “Books and Records”) for the longer of (i) five (5) years or (ii) the period of time set forth in their respective records retention policies on the Closing Date or for such longer period as may be required by law or any applicable court order.

(b) The parties will allow each other reasonable access to such Books and Records, and to personnel having knowledge of the whereabouts and/or contents of such Books and Records, for legitimate business reasons, such as the preparation of tax returns or the defense of litigation. Each party shall be entitled to recover its out-of-pocket costs (including, without limitation, copying costs) incurred after the Closing in providing such records and/or personnel to the other party. The requesting party will hold in confidence all confidential information identified as such by, and obtained from, the disclosing party, any of its officers, agents, representatives or employees, provided, however, that information which (i) was in the public domain; (ii) was in fact known to the requesting party prior to disclosure by the disclosing party, its officers, agents, representatives or employees; or (iii) becomes known to the requesting party from or through a third party not under an obligation of non-disclosure to the disclosing party, shall not be deemed to be confidential information.

5.6. Employees. Buyer may consider making an offer of employment to certain current or former employees of SeraCare, upon such terms, and with such compensation and benefits, as Buyer may determine in its sole discretion.

5.7. Product Shipment and Inventory Reconciliation. Buyer shall use its best efforts to remove the Inventory (as defined below) from any location other than a public warehouse on the Closing Date at Buyer’s sole cost. From and after the date hereof, Buyer shall be responsible for any facility relocation charges incurred by SeraCare with respect to the Inventory of the Business, whether such charges are incurred prior to, on or after the Closing Date. Where the Inventories are stored in a public warehouse, SeraCare will provide any necessary authorization to permit Buyer to remain or withdraw from such public warehouse. Any removed Inventories shall be transported, at Buyer’s expense, to warehouse locations designated by Buyer. Buyer shall also be responsible for removing, at its sole expense and risk, all equipment and other items constituting Assets acquired by Buyer hereunder which are located at any of SeraCare and its subsidiaries facilities not acquired by Buyer hereunder. Buyer shall promptly reimburse SeraCare for any out-of-pocket costs, fees and expenses incurred by SeraCare and its subsidiaries in connection with the removal, storage or relocation of the Assets from the premises of SeraCare and its subsidiaries or elsewhere where such Assets may be located, whether such charges are incurred prior to, on or after the Closing Date; provided, however, that Buyer shall not reimburse SeraCare for such out-of-pocket costs, fees and expenses in connection with the storage of the Inventory from the date hereof and for thirty (30) days after the Closing Date. For purposes of this Section 5.7, the term “Inventory” shall mean all finished products (other than

finished products that have been billed and are being held for customers’ accounts) of the Business on the Closing Date and all work-in-process, raw materials and packaging materials used in connection therewith, principally related to the Business.

5.8. “As Is” Condition. Notwithstanding anything herein to the contrary, Buyer agrees that it shall accept all Assets in an “As Is” “Where Is” condition at the Closing Date. SeraCare makes no warranty with respect to the value, condition or use of the Assets, whether expressed or implied, including, without limitation, any implied warranty of merchantability or fitness for a particular purpose, except as otherwise provided in Article III hereof.

(a) Until the Closing shall actually have occurred, Buyer acknowledges that it remains subject to the Confidentiality Letter. Buyer further acknowledges that the value to SeraCare of the transactions contemplated by this Agreement would be substantially diminished if Buyer or any of its affiliates were to solicit the employment of any employee of SeraCare or its affiliates (other than pursuant to the terms of the Confidentiality Letter and pursuant to Section 5.6 prior to the Closing Date and other than an hourly worker or an employee who serves in a clerical function). Accordingly, Buyer agrees that, for a period of three (3) years following the Closing Date, neither Buyer nor any affiliate or subsidiary of Buyer shall solicit the employment of any employee or employ any person who is an employee of SeraCare or any of its affiliates (other than pursuant to the terms of the Confidentiality Letter and pursuant to Section 5.6 and other than an hourly worker or an employee who serves in a clerical function); provided, however, that the foregoing provision will not prevent Buyer from hiring any employee of SeraCare or any of its affiliates (i) who responds to a public advertisement placed by Buyer, (ii) who has not been employed by SeraCare during the preceding six (6) months or (iii) who has been terminated by SeraCare.

(b) SeraCare and Buyer agree that a monetary remedy for a breach of the agreements set forth in this Section 5.9 will be inadequate and impracticable and further agree that such a breach would cause irreparable harm, and that the non-breaching party shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damages. In the event of such a breach, the breaching party agrees that the non-breaching party shall be entitled to such injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions as a court of competent jurisdiction shall determine.

(c) If any of the provisions of this Section 5.9 is invalid in part, it shall be curtailed, as to time, location or scope, to the minimum extent required for its validity under the laws of the United States and shall be binding and enforceable with respect to Buyer as so curtailed.

5.10. Financial Capacity. Buyer shall perform all further acts that may be reasonably necessary to provide all funds necessary to enable Buyer to consummate the transactions contemplated by this Agreement and to fund all disbursements of the Business on the Closing Date.

5.11. Financing. Effective at the opening of business on the Closing Date, Buyer shall be responsible for funding all disbursements related to the Assets acquired under this Agreement to the extent such disbursements relate to periods from and after the Closing Date. Any cash, cash equivalents, similar investments, certificates of deposit, Treasury bills, accounts receivable and other marketable securities held by the Business at the Closing shall be treated by the parties consistent with Section 1.3.

(a) Subject to Section 1.3(f), all payments and reimbursements made in the ordinary course of business by any third party in the name of or to SeraCare or any affiliate thereof in connection with or arising out of the Assets or Assumed Liabilities after the Closing Date, or any of the Closing Inventory that is returned to SeraCare or any affiliate thereof, shall be held by such person in trust for the benefit of Buyer and, immediately upon receipt by such person of any such payment, reimbursement or returned portion of the Closing Inventory, such person shall pay over to Buyer the amount of such payment or reimbursement or deliver to Buyer such portion of the Closing Inventory without right of set off.

(b) All payments and reimbursements made in the ordinary course of business by any third party in the name of or to Buyer or any affiliate thereof in connection with or arising out of the Excluded Assets or Excluded Liabilities after the Closing Date shall be held by such person in trust for the benefit of SeraCare and, immediately upon receipt by such person of any such payment or reimbursement, such person shall pay over to SeraCare the amount of such payment or reimbursement without right of set off.

(c) SeraCare covenants and agrees that it will forward to Buyer any mail (physical, electronic or otherwise), facsimile or telephone inquiries of actual or potential clients, customers, suppliers and vendors of or relating to the Business, including, without limitation, customer orders.

(a) SeraCare acknowledges that the agreements and covenants contained in this Section 5.12 are essential to protect the value of the Business being acquired by Buyer. Therefore, SeraCare agrees that for the period commencing on the Closing Date and ending on the fifth (5th) anniversary of the Closing Date (the “Restricted Period”), neither SeraCare or any of its affiliates shall:

(i) participate or engage, directly or indirectly, whether as an agent, consultant, director, shareholder, partner, joint venturer, investor, lender, licensor or otherwise in the sale of human clinical specimens and their accompanying medical information for use in drug discovery (a “Competing Business”);

(ii) solicit or attempt to solicit for a Competing Business any customer or account included within the Assets; or

(iii) solicit the employment of, whether for SeraCare or any Competing Business, any Business Employee.

(b) SeraCare and Buyer agree that a monetary remedy for a breach of the agreements set forth in this Section 5.12 may be inadequate and impracticable and further agree that such a breach may cause irreparable harm, and that the non-breaching party shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damages. In the event of such a breach, the breaching party agrees that the non-breaching party shall be entitled to such injunctive relief, including temporary restraining orders, preliminary injunctions and permanent injunctions as a court of competent jurisdiction shall determine without the necessity of posting bond.

(c) If any of the provisions of this Section 5.12 is found to be invalid by a court of competent jurisdiction, it shall be curtailed, as to time, location or scope, to the minimum extent required for its validity under the laws of the United States and shall be binding and enforceable with respect to SeraCare as so curtailed.

All consents, licenses, approvals, authorizations and orders of federal, state and foreign governmental and regulatory authorities set forth on Schedule 6.1(b) as are necessary in connection with the transfer of the Assets to Buyer or which if not obtained would be reasonably likely to subject Buyer or SeraCare, or any stockholder, officer, director or agent of any such person to civil or criminal liability or could render such transfer void or voidable (the “Required Consents”) shall have been obtained.

(c) Third Party Consents. All required third party licenses, approvals or consents shall have been obtained, including the consents of SeraCare’s customers if any such consents are required pursuant to the terms of the Customer Contracts or the Disclosed Contracts; provided, however, that to the extent that any Customer Contract or Disclosed Contract is not expressly assignable or transferable without the consent of a third party, SeraCare will use reasonable efforts to cooperate with Buyer to negotiate with the applicable third party regarding the assignment or transfer of such Customer Contract or Disclosed Contract, and provided further, that the Closing shall not be made contingent on the valid assignment or transfer of any such Customer Contract or Disclosed Contract. SeraCare and Buyer agree that there shall be excluded from the Assets any Assumed Agreements that are not assignable or transferable pursuant to the Bankruptcy Code or otherwise without the consent of any person other than SeraCare, to the extent such consent shall not have been given prior to the Closing; provided, however, that SeraCare shall have the obligation to use all commercially reasonable

efforts to endeavor to obtain the necessary consents to the assignment thereof and, upon obtaining the requisite consents thereto, such Assumed Agreements shall be assigned to the Buyer at no cost free and clear of all liens other than the Permitted Liens; provided, that SeraCare shall not be required to incur more than immaterial costs to obtain any consent.

(a) SeraCare shall defend, indemnify and hold Buyer and its affiliates harmless from and against and in respect of any and all losses, liabilities, damages, judgments, settlements and expenses, including reasonable attorneys’ fees, incurred by Buyer and its affiliates (hereinafter “Buyer Losses”) which arise out of (i) any breach of any of the representations and warranties contained in Section 3 hereof, (ii) the ownership, operation or use of any of the Excluded Assets or Excluded Liabilities, or (iii) Excluded Liabilities. Buyer shall give SeraCare prompt written notice of any third party claim which may give rise to any indemnity obligation under this Section 8.1, together with the estimated amount of such claim, and SeraCare shall have the right to assume the defense of any such claim through counsel of its own choosing, by so notifying Buyer within sixty (60) days of receipt of Buyer’s written notice. Failure to give prompt notice shall not affect the indemnification obligations hereunder in the absence of actual prejudice. If Buyer desires to participate in any such defense assumed by SeraCare, it may do so at its sole cost and expense. If SeraCare declines to assume any such defense, it shall be liable for all reasonable costs and expenses of defending such claim incurred by Buyer, including reasonable fees and disbursements of counsel. Neither party shall, without the prior written consent of the other party, which shall not be unreasonably withheld, settle, compromise or offer to settle or compromise any such claim or demand on a basis which would result in the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the other party or any subsidiary or affiliate thereof or if such settlement or compromise does not include an unconditional release of the other party for any liability arising out of such claim or demand or any related claim or demand.

(b) The foregoing obligation to indemnify Buyer and its affiliates set forth in Section 8.1(a) shall be subject to each of the following limitations:

(i) SeraCare’s indemnification obligations set forth in Section 8.1(a), including SeraCare’s indemnification obligation with respect to any breach of any of the representations and warranties contained in Section 3 hereof, shall survive for only a period of twelve (12) months after the Closing, and thereafter all such representations and warranties of SeraCare under this Agreement shall be extinguished. No claim for the recovery of any Buyer Losses may be asserted by Buyer after such twelve (12) month period; provided, however, that claims first asserted in writing with reasonable specificity within such period shall not thereafter be barred;

(ii) No reimbursement for Buyer Losses asserted against SeraCare under Section 8.1(a) above shall be required unless and until the cumulative aggregate amount of such Buyer Losses equals or exceeds twenty thousand dollars ($20,000) (the “Seller Threshold”) and then only to the extent that the cumulative aggregate amount of Buyer Losses, as finally determined, exceeds said Threshold.

(iii) SeraCare’s liability to Buyer and its affiliates under this Section 8.1 for Buyer Losses in excess of the Seller Threshold shall not exceed the aggregate amount of the First Royalty Amount of the Purchase Price as set forth in Section 2.2(c). No claims for Buyer Losses under this Section 8.1 shall be paid until after the calculation of the First Royalty Amount due and payable to SeraCare has been made, and no interest shall accrue on such claims. The exclusive method of payment for any amounts owed by SeraCare for the payment of claims for Buyer Losses hereunder shall be to subtract the Buyer Losses (as otherwise qualified or limited herein) from the amount of the First Royalty Amount (if any) due and payable to SeraCare.

(iv) If Buyer receives any insurance proceeds related to Buyer Losses, Buyer shall be required to deduct any insurance proceeds received in respect of such Buyer Losses from the amount it seeks to recover from SeraCare pursuant to this Section 8.1. To the extent that Buyer receives any insurance proceeds pursuant to an insurance claim subsequent to Buyer’s receipt of payment from SeraCare for any Buyer Losses hereunder, Buyer shall promptly reimburse SeraCare in the amount of any such insurance proceeds subsequently received.

(c) The indemnities provided in this Section 8.1 shall survive the Closing. The indemnity provided in this Section 8.1 shall be the sole and exclusive remedy of the indemnified party against the indemnifying party at law or equity for any matter covered by this Agreement.

(d) In no event shall SeraCare or its affiliates be liable to Buyer or its affiliates for special, indirect, incidental, consequential or punitive damages.

(a) Buyer shall defend, indemnify and hold SeraCare and its affiliates harmless from and against and in respect of any and all losses, liabilities, damages, judgments,

settlements and expenses, including reasonable attorney fees, incurred by SeraCare and its affiliates (hereinafter “Seller’s Losses”; together with Buyer Losses, “Losses”) arising out of (i) any breach of any of the representations and warranties contained in Section 4 hereof, (ii) the ownership, operation or use of the Assets on or after the Closing Date, or (iii) all Assumed Liabilities. SeraCare shall give Buyer prompt written notice of any third party claim which may give rise to any indemnity obligation under this Section 8.2, together with the estimated amount of such claim, and Buyer shall have the right to assume the defense of any such claim through counsel of its own choosing, by so notifying SeraCare within sixty (60) days of receipt of SeraCare’s written notice. Failure to give prompt notice shall not affect the indemnification obligations hereunder in the absence of actual prejudice. If SeraCare desires to participate in any such defense assumed by Buyer it may do so at its sole cost and expense. If Buyer declines to assume any such defense, it shall be liable for all costs and expenses of defending such claim incurred by SeraCare, including reasonable fees and disbursements of counsel. Neither party shall, without the prior written consent of the other party, which shall not be unreasonably withheld, settle, compromise or offer to settle or compromise any such claim or demand on a basis which would result in the imposition of a consent order, injunction or decree which would restrict the future activity or conduct of the other party or any subsidiary or affiliate thereof or if such settlement or compromise does not include an unconditional release of the other party for any liability arising out of such claim or demand.

(b) The foregoing obligation to indemnify SeraCare and its affiliates set forth in Section 8.2(a) shall be subject to each of the following limitations:

(i) Buyer’s indemnification obligations set forth in Section 8.2(a), including Buyer’s indemnification obligation with respect to any breach of any of the representations and warranties contained in Section 4 hereof, shall survive for only a period of twelve (12) months after the Closing, and thereafter all such representations and warranties of Buyer under this Agreement shall be extinguished. No claim for the recovery of such Seller’s Losses may be asserted by SeraCare after such twelve (12) month period; provided, however, that claims first asserted in writing with reasonable specificity within such period shall not thereafter be barred.

(ii) No reimbursement for Seller’s Losses asserted against Buyer under Section 8.2(a) above shall be required unless and until the cumulative aggregate amount of such Seller’s Losses equals or exceeds twenty thousand dollars ($20,000) (the “Buyer Threshold”), and then only to the extent that the cumulative aggregate amount of Seller’s Losses, as finally determined, exceeds said Buyer Threshold.

(iii) If SeraCare receives any insurance proceeds related to Seller Losses, SeraCare shall be required to deduct any insurance proceeds received in respect of such Seller Losses from the amount it seeks to recover from Buyer pursuant to this Section 8.2. To the extent that SeraCare receives any insurance proceeds pursuant to an insurance claim subsequent to SeraCare’s receipt of payment from Buyer for any Seller Losses hereunder, SeraCare shall promptly reimburse Buyer in the amount of any such insurance proceeds subsequently received.

(c) The indemnities provided in this Section 8.2 shall survive the Closing. The indemnity provided in this Section 8.2 shall be the sole and exclusive remedy of the indemnified party against the indemnifying party at law or equity for any matter covered by this Agreement.

(d) In no event shall Buyer be liable to SeraCare or its affiliates for special, indirect, incidental, consequential or punitive damages.

8.3. Indemnification Calculations. The parties agree that any indemnification payments made pursuant to this Agreement shall be treated for Tax purposes as an adjustment to the Purchase Price, unless otherwise required by applicable law.

9.1. Termination Events. Without prejudice to other remedies which may be available to the parties by law or this Agreement, this Agreement may be terminated and the transactions contemplated herein may be abandoned:

(b) by either party, if there shall be in effect a final order restraining, enjoining or otherwise prohibiting the consummation of the transaction contemplated by this Agreement;

(c) by either party, if there shall have been a material breach of any representation, warranty, covenant or agreement on the part of the other party contained in this Agreement such that the conditions set forth in either Section 6.2(a) or Section 6.3(a), as applicable, would not be satisfied and which, if curable, shall not have been cured prior to the earlier of (x) thirty (30) days after the giving of written notice of such material breach by the non-breaching party to the breaching party and (y) March 31, 2007; provided, however, that neither Buyer nor SeraCare shall have the right to terminate this Agreement pursuant to this clause (c) if the party giving notice of a material breach is then in material breach of any of its representations, warranties, covenants or agreements set forth in this Agreement such that the conditions set forth in either Section 6.2(a) or Section 6.3(a), as applicable, would not be satisfied; or

(d) by any party by notice to the other party if the Closing shall not have been consummated on or before March 31, 2007, unless extended by mutual written agreement of the parties hereto, so long as the party terminating this Agreement shall not be in default or breach hereunder.

9.2. Effect of Termination. In the event of any termination of the Agreement as provided in Section 9.1 above, this Agreement shall forthwith become wholly void and of no further force and effect and there shall be no liability on the part of Buyer or SeraCare, except that (i) the confidentiality and non-solicitation obligations of Buyer and SeraCare under this Agreement shall remain in full force and effect and (ii) termination shall not preclude either party from suing the other party for breach of this Agreement.

The parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by negotiations between executives who have authority to settle the controversy. Any party may give the other party written notice of any dispute not resolved in the normal course of business. Within twenty (20) days after delivery of said notice, executives of both parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to exchange relevant information and to attempt to resolve the dispute. If the matter has not been resolved within sixty (60) days of the disputing party’s original notice, or if the parties fail to meet within twenty (20) days, either party may initiate legal proceedings to resolve the controversy or claim. If a party’s negotiator intends to be accompanied at a meeting by an attorney, the other party’s negotiator shall be given at least three (3) business days’ notice of such intention and may also be accompanied by an attorney. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and state rules of evidence.

11.1. Notices. All communications provided for hereunder shall be in writing and shall be deemed to be given when delivered in person or by private courier with receipt, when telefaxed and received, or three (3) days after being deposited in the United States mail, first-class, registered or certified, return receipt requested, with postage paid and,

or to such other address as any such party shall designate by written notice to the other parties hereto.

11.2. Bulk Transfers. Buyer waives compliance with the provisions of all applicable laws relating to bulk transfers in connection with the Asset Purchase.

11.3. Transaction Taxes. SeraCare shall be responsible for the payment of all sales and transfer taxes, if any, which may be payable with respect to the consummation of the transactions contemplated by this Agreement and to the extent any exemptions from such taxes are available Buyer and SeraCare shall cooperate to prepare any certificates or other documents necessary to claim such exemptions.

11.4. Further Assurances; Asset Returns. Upon request from time to time, SeraCare shall execute and deliver all documents, take all rightful oaths, and do all other acts that may be reasonably necessary or desirable, in the reasonable opinion of counsel for Buyer, to perfect or record the title of Buyer, or any successor of Buyer, to the Assets transferred or to be transferred under this Agreement, or to aid in the prosecution, defense, or other litigation of any rights arising from said transfer (provided that Buyer shall reimburse SeraCare for all out of pocket costs and expenses resulting from any such request). In the event that Buyer receives any assets of SeraCare that are not intended to be transferred pursuant to the terms of this Agreement, whether or not related to the Business, Buyer agrees to promptly return such assets to SeraCare at SeraCare’s expense.

11.5. Other Covenants. To the extent that any consents needed to assign to Buyer any of the Assets have not been obtained on or prior to the Closing Date, this Agreement shall not constitute an assignment or attempted assignment thereof if such assignment or attempted assignment would constitute a breach thereof. If any such consent shall not be obtained on or prior to the Closing Date, then SeraCare and Buyer, if required under applicable law, shall use their reasonable efforts in good faith to obtain such consent as promptly as practicable thereafter.

11.6. Expenses. Subject to Section 11.3, SeraCare and Buyer shall each pay their respective expenses (such as legal, investment banker and accounting fees) incurred in connection with the origination, negotiation, execution and performance of this Agreement.

11.7. Non-Assignability. This Agreement shall inure to the benefit of and be binding on the parties hereto and their respective successors and permitted assigns. This Agreement shall not be assigned by either party hereto without the express prior written consent of the other party, and any attempted assignment, without such consents, shall be null and void.

11.8. Amendment; Waiver. This Agreement may be amended, supplemented or otherwise modified only by a written instrument executed by the parties hereto. No waiver by either party of any of the provisions hereof shall be effective unless explicitly set forth in writing and executed by the party so waiving. Except as provided in the preceding sentence, no action taken pursuant to this Agreement, including without limitation, any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of

compliance with any representations, warranties, covenants, or agreements contained herein, and in any documents delivered or to be delivered pursuant to this Agreement and in connection with the Closing hereunder. The waiver by any party hereto of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach.

(a) Buyer acknowledges and agrees that SeraCare is not making any representation or warranty whatsoever, express or implied, including, without limitation, in respect of SeraCare, the Business or the Assets, except those representations and warranties of SeraCare explicitly set forth in this Agreement or in the schedules hereto prepared by SeraCare. Each of Buyer and SeraCare agrees neither SeraCare nor any of the respective officers, directors, stockholders, employees, affiliates, representatives or agents of SeraCare shall have any liability or responsibility arising out of, or relating to, any information (whether written or oral), documents or materials furnished by SeraCare or any of its officers, directors, stockholders, employees, affiliates or any of their respective representatives or agents, and any information, documents or materials made available to Buyer in certain “data rooms”, management presentations or any other form in expectation of the transactions contemplated by this Agreement.

(b) All Exhibits and Schedules hereto are hereby incorporated by reference and made a part of this Agreement. Any fact or item which is clearly disclosed on any Schedule or Exhibit to this Agreement in such a way as to make its relevance to a representation or representations made elsewhere in this Agreement or to the information called for by another Schedule or other Schedules (or Exhibit or other Exhibits) to this Agreement readily apparent shall be deemed to be an exception to such representation or representations or to be disclosed on such other Schedule or Schedules (or Exhibit or Exhibits), as the case may be, notwithstanding the omission of a reference or cross-reference thereto. Any fact or item disclosed on any Schedule or Exhibit hereto shall not by reason only of such inclusion be deemed to be material and shall not be employed as a point of reference in determining any standard of materiality under this Agreement.

11.10. Third Parties. This Agreement does not create any rights, claims or benefits inuring to any person that is not a party hereto nor create or establish any third party beneficiary hereto.

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

11.12. Venue and Jurisdiction. Venue for any action or proceeding pertaining to the construction or enforcement of this Agreement shall be the Bankruptcy Court, and the parties hereto consent to the Bankruptcy Court’s exercise of jurisdiction over them with respect to any such action or proceeding.

(a) “affiliate” of a person means a person that directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, the first mentioned person;

(b) “Knowledge” means the actual knowledge of the following officers or employees of SeraCare: Susan Vogt, President and Chief Executive Officer; Gregory Gould, Chief Financial Officer; and Kathi Shea, Vice President, SeraCare Biosciences.

(c) “person” means an individual, corporation, partnership, association, trust, limited liability company, limited partnership, limited liability partnership, partnership, incorporated organization, other entity or group (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended); and

(d) “subsidiary” or “subsidiaries” of Buyer, SeraCare or any other person means any person of which Buyer, SeraCare or such other person, as the case may be (either alone or through or together with any other subsidiary), owns, directly or indirectly, 50% or more of the stock or other equity interests the holder of which is generally entitled to vote for the election of the board of directors or other governing body of such person.

11.14. Entire Agreement. This Agreement, and the Schedules and Exhibits hereto set forth the entire understanding of the parties hereto and no modifications or amendments to this Agreement shall be binding on the parties unless in writing and signed by the party or parties to be bound by such modification or amendment.

11.15. Section Headings; Table of Contents. The section headings contained in this Agreement and the Table of Contents to this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

11.16. Severability. If any provision of this Agreement shall be declared by any court of competent jurisdiction to be illegal, void or unenforceable, all other provisions of this Agreement shall not be affected and shall remain in full force and effect.

11.17. Counterparts. This Agreement may be executed in any number of counterparts, including by electronic mail or facsimile, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument.

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed as of the date first above written.
