THIS ASSET PURCHASE AGREEMENT (this “Agreement”) is entered into as of November 8, 2006, (the “Agreement Date”) between MedImmune, Inc., a Delaware corporation (“Seller”), and ZLB Behring AG, a Swiss corporation (“Purchaser”).

Recitals

WHEREAS, Seller owns certain assets relating to the manufacture, distribution, marketing and sale of a biological product known as CytoGam® (cytomegalovirus immune globulin intravenous) (the “Product”), which assets are referred to herein as the Acquired Assets (as more particularly defined below); and

WHEREAS, Seller desires to sell to Purchaser, and Purchaser desires to purchase from Seller, the Acquired Assets (as defined below), and Purchaser has agreed to assume from Seller the Assumed Liabilities (as defined below), all on the terms and conditions set forth in this Agreement; and

WHEREAS, except as otherwise expressly provided, capitalized terms used herein shall have the meanings set forth in Annex A.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

1.                                      SALE AND PURCHASE OF ASSETS.

1.1          Purchase and Sale.  On the terms and subject to the conditions of this Agreement, Seller shall sell, assign, transfer, convey and deliver to Purchaser, and Purchaser shall purchase, from Seller, as of the Effective Time, all the right, title and interest of Seller in, to and under the Acquired Assets in consideration for payment of the Purchase Price (as defined below) and the assumption by Purchaser of the Assumed Liabilities. The purchase and sale of the Acquired Assets and the assumption of the Assumed Liabilities are referred to in this Agreement collectively as the “Acquisition.”

1.2          Transfer of Assets.

(a)           Acquired Assets.  The term “Acquired Assets” means all Seller’s rights, title and interest in, to and under those certain assets set forth below and further described in Schedule 1.2(a), subject to any limitations, restrictions or conditions imposed under the Assigned Contracts, the Assumed Liabilities or this Agreement:

(viii)        the Seller’s interest in the database software and the data identified on Schedule 1.2(a)(viii);

(x)            all goodwill relating to the Acquired Assets; and

(xi)           all rights in and to all warranties, guarantees and indemnities with respect to the Acquired Assets or Assumed Liabilities, and, except as provided in Section 1.2(b)(vi), all rights, claims or causes of action of Seller and/or any of its Affiliates relating to any Acquired Asset or any Assumed Liability, whether known or unknown, contingent or noncontingent.

(b)           Excluded Assets.  Notwithstanding anything to the contrary in Section 1.2(a) and elsewhere in this Agreement, all assets of Seller other than the Acquired Assets (the “Excluded Assets”) are not part of the Acquisition.  By way of clarification and not limitation, the following assets (as further described on Schedule 1.2(b)) shall be Excluded Assets and shall remain the property of Seller after the Closing:

(vii)         all rights of Seller or any of its Affiliates under this Agreement, the Related Instruments and the Ancillary Agreements; and

(viii)        all Retained Information.

2

(c)           Liens and Encumbrances.  Subject to any limitations or conditions imposed by the Assigned Contracts and as otherwise provided in this Agreement, Purchaser is acquiring the Acquired Assets free and clear of all liabilities, obligations and commitments of Seller or any of its Affiliates, other than the Assumed Liabilities, and free and clear of all Liens and Encumbrances, other than Permitted Liens.

1.3          Assumed and Excluded Liabilities.

(a)           Assumed Liabilities.  Upon the terms and subject to the conditions of this Agreement, Purchaser hereby assumes, and from and after the Effective Time Purchaser shall pay, perform, discharge and otherwise fully satisfy when due, any and all liabilities, obligations and commitments arising out of or related to the liabilities set forth below and further described in Schedule 1.3(a) (the “Assumed Liabilities”):

(i)            except to the extent set forth in Section 1.3(b)(i), all liabilities, obligations and commitments arising out of or relating to any product liability, breach of warranty or similar claim for injury to person or property, if asserted following the Effective Time, to the extent that such liabilities, obligations or commitments (A) result from the use or misuse of Product included in any lot released by or on behalf of Purchaser after the Effective Time (“Purchaser Lot”), (B) otherwise relate to Product included in any Purchaser Lot (including all Proceedings relating to any such liabilities) or (C) subject to the Transition Services Agreement, relate to, or derive from, the sale, handling or distribution of the Product (including Product from any lot released by or on behalf of Seller prior to the Effective Time (“Seller Lot”)) after the Effective Time by or on behalf of Purchaser;

(ii)           except to the extent specifically provided in Section 1.3(b)(ii), all liabilities arising out of or relating to the ownership of the Governmental Authorizations from and after the Effective Time, including the responsibility for all product complaints, recalls, lookbacks, market withdrawals and field corrections with respect to any Product included in any Purchaser Lot;

(iii)          subject to Section 5.5 below, all liabilities arising out of or relating to the return of any Product included in any lot from which Seller had not shipped any vials of Product prior to the Effective Time;

(iv)          subject to Section 5.5, all liabilities, obligations and commitments arising out of or relating to any rebates, chargebacks, or administrative fees related to any Product that are asserted or requested on or after [*****];

(v)           all liabilities for Taxes arising out of or relating to, directly or indirectly, the Acquired Assets (including the Product), or the ownership, sale or lease of any of the Acquired Assets, other than the Excluded Tax Liabilities, and in each case only to the extent such Taxes relate to periods or transactions after the Effective Time;

3

(vi)          all liabilities arising on or after the Effective Time under or relating to, directly or indirectly, the Assigned Contracts, other than liabilities for breaches occurring prior to the Effective Time;

(vii)         all other liabilities, obligations and commitments of whatever kind and nature, primary or secondary, direct or indirect, absolute or contingent, known or unknown, whether or not accrued, arising out of or relating to, directly or indirectly, the Acquired Assets (including the Product), or the ownership, sale or lease of any of the Acquired Assets, or the marketing, sale or distribution of the Product, or the conduct of the Product-Related Business, but in each case only to the extent arising after the Effective Time; and

(viii)        except to the extent specifically provided in Section 1.3(b), any and all other liabilities, obligations and commitments, of whatever kind and nature, primary or secondary, direct or indirect, absolute or contingent, known or unknown, whether or not accrued, arising out of or relating to, directly or indirectly, the Acquired Assets (including the Product), to the extent arising after the Effective Time.

For avoidance of doubt, nothing in this Section 1.3(a) is intended to, or shall be interpreted to, limit or otherwise reduce the Liabilities of Purchaser as they may occur and/or exist after the Effective Time by virtue of Purchaser’s ownership of the Acquired Assets or operation of the Product-Related Business, but rather, this Section 1.3(a) is solely intended to identify and provide for the assumption by Purchaser of those Liabilities of Seller that are specifically assumed by Purchaser hereunder and which, but for such assumption, would remain Liabilities of Seller.

(b)           Excluded Liabilities.  Notwithstanding any other provision of this Agreement or any Related Instrument, Purchaser is not hereby assuming any Excluded Liability, each of which shall be retained and paid, performed and discharged when due by Seller. The term “Excluded Liability” shall mean those liabilities which are not Assumed Liabilities, including:

(i)            all liabilities arising out of or relating to any product liability, breach of warranty or similar claim for injury to person or property, to the extent such liabilities, obligations or commitments (A) result from the use or misuse of Product included in any Seller Lot, or (B) otherwise relate to Product included in any Seller Lot (including all Proceedings relating to any such liabilities), except in the case of both (A) and (B) to the extent such liabilities relate to or derive from the sale, handling or distribution of such Product after the Effective Time by or on behalf of Purchaser;

(ii)           all liabilities arising out of or relating to the ownership of the Governmental Authorizations prior to the Effective Time, including the responsibility for all product complaints, recalls, market withdrawals and field corrections with respect to any Product included in any Seller Lot;

4

(iii)          subject to Section 5.5 below, all liabilities arising out of or relating to the return of any Product included in any lot from which Seller had shipped at least one Product vial prior to the Effective Time, provided, that Purchaser maintains substantially the same Product return policies with respect to Product in any lots for which Seller retains return liability;

(iv)          subject to Section 5.5 below, all liabilities, obligations and commitments arising out of or relating to any rebates, chargebacks, or administrative fees related to any Product that are asserted or requested prior to [*****];

(v)           all liabilities arising out of or claims or complaints originating, occurring, arising or brought against Seller relating to or affecting the Product or the Product-Related Business with respect to any time prior to the Effective Time;

(vi)          any Tax payable with respect to any business, asset, property or operation of Seller or any member of any affiliated group of which Seller is a member (including any Taxes relating to or arising out of the operation of the Acquired Assets) relating to any Pre-Effective Time Tax Period, other than any Tax for which Purchaser is responsible pursuant to Section 5.8, provided that notwithstanding Section 5.8, Purchaser shall not assume any liability for transfer Taxes to the extent such transfer Tax is measured by gain realized by Seller from the sale of the Acquired Assets (an “Excluded Tax Liability”) and, for this purpose, in the case of a taxable period that begins before and ends after the Effective Time (a “Straddle Period”), (i) any Tax that is based on income, revenue, sales, payments or wages shall be allocated between the portion of the Straddle Period that is a Pre-Effective Time Tax Period and the remainder of the Straddle Period, as if based on a closing of the books as of the Effective Time, (ii) and any other Tax shall be allocated in proportion to the number of the days of the Straddle Period ending before and after the Effective Time;

(vii)         any liability of Seller or any of its Affiliates arising out of or relating to any Excluded Asset;

(viii)        any liability of Seller or any of its Affiliates for royalties accrued in connection with the manufacture and sale of Product prior to the Effective Time;

(ix)           any liability of Seller or any of its Affiliates for accounts payable incurred in connection with the manufacture and sale of Product prior to the Effective Time;

(x)            except as otherwise expressly provided in this Agreement or the Transition Services Agreement, any liability for acts of Seller after the Effective Time; and

(xi)           except to the extent specifically provided in Section 1.3(a) any and all other liabilities, obligations and commitments of whatever kind and nature, primary or secondary, direct or indirect, absolute or contingent, known or unknown, whether or not accrued, arising out of or relating to, directly or indirectly, the Acquired Assets (including the Product) but only to the extent related to any period prior to the Effective Time.

5

(c)           No Offset.  Each of Purchaser’s and Seller’s obligations under this Section 1.3 will not be subject to offset or reduction by reason of any actual or alleged breach of any representation, warranty or covenant contained in this Agreement or any Ancillary Agreement or Related Instrument or any right or alleged right to indemnification hereunder.

1.4          Closing.  The closing of the Acquisition provided for in this Agreement (the ”Closing”) will take place at the offices of Seller’s counsel, Hogan & Hartson L.L.P. at 555 Thirteenth Street, N.W., Washington, D.C. at a mutually agreeable time on the date three (3) business days after the date on which all of the conditions precedent set forth in Sections 6 and 7 below are satisfied or waived (or such other date as Seller and Purchaser mutually agree).  The time of consummation of the transactions contemplated by this Agreement (“Effective Time”) is deemed to be at 12:01 a.m. Maryland time on the date on which the Closing occurs (the “Closing Date”).

1.5          Purchase Deposit.

(a)           Payment of Deposit.  Upon execution of this Agreement, Purchaser shall deliver to Seller a deposit of Five Million Dollars ($5,000,000) (the “Purchase Deposit”), to be held by Seller.  For purposes of calculating any accrued interest on the Purchase Deposit, the Parties agree to use an interest rate of [*****] per annum from and after the date of delivery.  The Purchase Deposit is a deposit against, and component of, the Purchase Price defined in Section 1.6 and shall be applied to the Purchase Price at the Closing.

(b)           Return of Deposit.  In the event that Purchaser terminates this Agreement as permitted pursuant to Section 9.1(c), the Purchase Deposit shall be returned to Purchaser.  The Purchase Deposit shall also be returned to Purchaser in the event the Agreement is terminated by mutual agreement pursuant to Section 9.1(a).  Interest on the Purchase Deposit shall be paid out to Purchaser when the Purchase Deposit is paid out.

(c)           Forfeit of Deposit.  The Purchase Deposit, plus accrued interest, shall be forfeited by Purchaser and be retained by Seller in the event that this Agreement is terminated by Seller pursuant to Section 9.1(b), other than pursuant to either condition precedent Section 6.3, Legal Proceedings, or Section 6.4, Consents, in which case the Purchase Deposit, plus accrued interest, shall be returned to Purchaser.

1.6          Purchase Price.  In addition to any other amounts due hereunder, in consideration of the sale, assignment, conveyance, license and delivery of the Acquired Assets hereunder, Purchaser shall assume the Assumed Liabilities and pay to Seller, by wire transfer of immediately available funds directly to an account designated by Seller, when due, the following (subject to the adjustments set forth in this Section 1, the “Purchase Price”):

(a)           Up-Front Payment.  An up-front component consisting of:

(i)            the Purchase Deposit paid pursuant to Section 1.5; and

(ii)           Forty-Five Million Dollars ($45,000,000) (the “Cash Amount”) payable at Closing.

6

(b)           Equipment Payment.  The value of (i) the manufacturing equipment set forth on Schedule 1.2(a)(vii) and (ii) the plasma database software set forth on Schedule 1.2(a)(viii) (collectively, the “Equipment Payment”) payable at Closing.

(c)           Inventory Payment.  The Estimated Inventory Value calculated pursuant to Section 1.8 (the “Initial Inventory Payment,” and together with the Cash Amount and the Equipment Payment, the “Closing Payment”) payable at Closing and subject to adjustment for any Inventory Variance in accordance with Section 1.8.

(d)           Milestone Payments.  The following Milestone Payments:

(i)            [*****] (the “First Milestone Payment”) payable when Cumulative Net Sales reach [*****] (the “First Milestone”);

(ii)           [*****] (the “Second Milestone Payment”) payable when Cumulative Net Sales reach [*****] (the “Second Milestone”); and

(iii)          [*****] (the “Third Milestone Payment” and together with the First Milestone Payment and the Second Milestone Payment, the “Milestone Payments”) payable when Cumulative Net Sales reach [*****] (the “Third Milestone” and together with the First Milestone and the Second Milestone, the “Milestones”).

1.7          Milestone Payments.

(a)           Payment Procedures.

(i)            Within ten (10) days after the end of each calendar quarter in which Cumulative Net Sales have reached a Milestone, Purchaser shall deliver to Seller a written notice stating that a Milestone has been reached and that a Milestone Payment will be made by Purchaser within thirty (30) days after the end of such calendar quarter (the “Milestone Notice”). Such Milestone Notice need not include specific Cumulative Net Sales information.  Even if Purchaser or Seller determines, subsequent to delivery of a Milestone Notice, that a Milestone was not reached, delivery of such Milestone Notice by Purchaser based on its good faith belief that reaching a Milestone was imminent, and the payment by Purchaser of the Milestone Payment based thereon, shall not constitute a breach of this Agreement.

(ii)           On or before thirty (30) days after the end of each calendar quarter, Purchaser shall deliver to Seller a report (the “Quarterly Sales Report”) setting forth (x) Product sales for such quarter and (y) Cumulative Net Sales as of the end of such quarter.  Purchaser shall pay each Milestone Payment to Seller within thirty (30) days of the end of the first such calendar quarter in which the Cumulative Net Sales exceed the applicable Milestone as set forth in the Quarterly Sales Report for such quarter or, even if Cumulative Net Sales have not exceeded such Milestone, within (30) days of the end of a calendar quarter for which a Milestone Notice was delivered by Purchaser.  Purchaser’s obligation to make the Milestone Payments shall not expire, regardless of the amount of time required for Cumulative Net Sales to exceed the applicable Milestones.

7

(b)           Combination Products.  If Purchaser markets, distributes or sells a formulation of the Product or if any derivative thereof is present in combination with another substance (a “Combination Product”), the Net Sales of the Product for the purposes of calculating the Cumulative Net Sales shall be based on the amount of Product (or any derivative thereof) in the Combination Product, as follows:

(i)            the amount of the Product (or any derivative thereof) in the Combination Product shall be compared to the amount of the Product (or any derivative thereof) present as monotherapy, in order to identify the percentage of the monotherapy dose of the Product present in the Combination Product (such percentage being referred to as the “Product Percentage”).

(ii)           the Product Percentage shall be multiplied by the sale price of the Combination Product and such product shall be deemed to be Net Sales of the Product for the purposes of calculating Cumulative Net Sales pursuant to this Section 1.7(b).

(c)           Diligence.  Purchaser shall use its commercially reasonable efforts to commercialize the Product and generate maximum sales of Product for so long as any Milestone remains unachieved.  Each Party acknowledges that there is no assurance that the Milestones will be achieved.

(d)           Records; Audit.

(i)            Records Retention.  Purchaser, its Affiliates and sublicensees will maintain complete and accurate books, records and accounts in sufficient detail to confirm the accuracy of Cumulative Net Sales information reported to Seller (including the Monthly Sales Reports) (the “Sales Records”), which Sales Records will be retained by the applicable Party until all Milestone Payments have been paid in full.

(ii)           Audit.  Seller will have the right, no more frequently than once per year, to have an independent certified public accounting firm of internationally recognized standing, reasonably acceptable to Purchaser (the “Independent Audit Accounting Firm”), to have access during normal business hours, and upon reasonable prior written notice, to such of the Sales Records of Purchaser, its Affiliates and sublicensees as may be reasonably necessary to verify the accuracy of information needed to calculate Milestone Payments required hereunder.  The Independent Audit Accounting Firm will disclose to the Parties only whether the Cumulative Net Sales reported by the Purchaser are correct or incorrect and the specific details concerning any discrepancies.  As between Seller and Purchaser, Seller will bear all costs of such audit, unless the audit reveals a discrepancy in Seller’s favor sufficient to trigger an unrealized Milestone Payment, in which case such audit shall not be counted for purposes of the once-per-year limitation of Seller’s audit rights.

8

(e)           Security for Milestone Payments.  If at any time prior to the full payment of the Milestone Payments, based on Cumulative Net Sales reflected in a Quarterly Sales Report, a Milestone Notice or the results of an audit under Section 1.7(d)(ii), the Purchaser fails to make any Milestone Payment when due, Seller shall notify Purchaser in writing of such failure to make a Milestone Payment, and Purchaser shall have fifteen (15) days from delivery of such written notice by Seller to pay to Seller the Milestone Payment then due.  If Purchaser fails to pay to Seller such Milestone Payment then due within such fifteen (15) day period, Purchaser shall within five (5) days after the expiration of such fifteen (15) day period (A) pay to Seller the Milestone Payment then due and (B) complete, execute and deliver an escrow agreement in substantially the form attached hereto as Exhibit F, with such changes as reasonably required by the Escrow Agent (the “Escrow Agreement”) and such related documents as are reasonbly required by the Escrow Agent in connection therewith, and deposit into an escrow account, pursuant to such Escrow Agreement, immediately available funds in the amount of the aggregate total unpaid Milestone Payments not then due (the “Escrow Deposit”).  The Escrow Agreement shall provide that a Milestone Payment shall be made from the Escrow Deposit to Seller upon (1) the joint instruction of the Parties, (2) Seller’s delivery of a statement of audit under Section 1.7(d)(ii) verifying Cumulative Net Sales in excess of a Milestone accompanied by Seller’s certification that Purchaser has failed to pay the corresponding Milestone Payment or (3) Seller’s delivery of a signed statement of the Independent Audit Accounting Firm indicating that it has been unable to complete an audit under Section 1.7(d)(ii) due to Purchaser’s failure to reasonably cooperate with any such audit for any ten-business day period (or periods).  The balance of the Escrow Deposit may be reduced to the amount of the unpaid Milestone Payments as future Milestone Payments are made.  The Escrow Deposit shall serve as security for the obligations of Purchaser to make Milestone Payments when due, and shall remain outstanding unless and until all such Milestone Payments have been received by Seller.

(f)            Acceleration of Milestone Payments.

(i)            (A)          A Change of Control of Purchaser (including, without limitation, failure by Purchaser to provide Seller with written notice no less than one (1) business day prior to a Change of Control of Purchaser), (B) the failure of Purchaser to provide the Quarterly Sales Report within fifteen (15) days after written notice from Seller of such failure, (C) the failure of Purchaser to provide any Milestone Notice when due, (D) the failure of Purchaser to make a Milestone Payment required pursuant to clause (A) of the second sentence of Section 1.7(e) or the failure of Purchaser to deposit the Escrow Deposit in accordance with clause (B) of the second sentence of Section 1.7(e), or (E) the failure of Purchaser to comply with the diligence requirements set forth in Section 1.7(c), shall each be referred to as a “Milestone Acceleration Event.”

(ii)           Upon the occurrence of a Milestone Acceleration Event under Section 1.7(f)(i)(A), Section 1.7(f)(i)(B), Section 1.7(f)(i)(C) or Section 1.7(f)(i)(D), or a Milestone Acceleration Event that remains uncured for a period of fifteen (15) days with respect to Section 1.7(f)(i)(E), unless Seller otherwise notifies Purchaser in writing, all of the unpaid Milestone Payments shall immediately become due and payable, and in addition to any other remedies available at law or equity, Seller may pursue all available remedies pursuant to the Parent Guarantee, simultaneously with or in advance of pursuing remedies under this Agreement, provided that Seller may not pursue remedies under the Parent Guarantee for Milestone Payments paid to Seller pursuant to the Escrow Agreement from the Escrow Deposit.  For the avoidance of doubt, (A) in the event any Milestone Payment is paid to Seller from the Escrow Deposit by the Escrow Agent, Seller shall no longer be entitled to seek payment of such Milestone Payment from Purchaser or Guarantor and (B) Seller agrees to use reasonable efforts for ninety (90) days to fund any Milestone Payment which is due from the Escrow Deposit, prior to pursuing remedies under the Parent Guarantee.  Also, if Purchaser has fully funded the Escrow Deposit, any Milestone Payment that is paid to Seller by Purchaser or Guarantor directly, rather than by Escrow Agent from the Escrow Deposit, shall result in a prompt disbursement to Purchaser by the Escrow Agent from the Escrow Deposit in the amount of such Milestone Payment, and Seller agrees to execute any joint written instruction required to effect such disbursement.

1.8          Inventory Calculations.

(a)           Inventory.  At least three (3) business days prior to the projected Closing Date, Seller shall deliver to Purchaser Schedule 1.8 which shall set forth an estimate of the amount of the value of the Inventory, determined in accordance with GAAP, as consistently applied by Seller (the “Estimated Inventory Value”) as of the Closing Date.  The final calculation of the value of the Inventory as of the Effective Time, determined in accordance with GAAP, as consistently applied by Seller (the “Inventory Value”) shall be determined, and a payment for the difference between the Inventory Value and the Estimated Inventory Value shall be made to Purchaser or Seller, as the case may be, as follows:

(i)            No later than twenty-one (21) days following the Closing, Seller shall examine its records to determine the quantities of Inventory existing as of the Effective Time and deliver a statement of Inventory Value to Purchaser (the “Statement of Inventory Value”).

(ii)           Purchaser may dispute any amounts reflected on the Statement of Inventory Value on the basis that the Inventory Value was not accurate or correctly determined, and Purchaser shall have access to such Product Records, including Retained Information, as are reasonably necessary to support such determination; provided, however, that Purchaser shall have notified Seller in writing of each disputed item, specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute, within fifteen (15) days after Seller’s delivery of the Statement of Inventory Value to Purchaser.  In the event of such a dispute, Seller and Purchaser shall attempt to reconcile their differences, and any resolution by them as to any disputed amounts shall be final, binding and conclusive on the Parties.  If Seller and Purchaser are unable to resolve any such dispute within fifteen (15) days after Purchaser’s delivery of its notice of dispute to Seller, Seller and Purchaser shall submit the items remaining in dispute for resolution to a mutually acceptable independent accounting firm of national reputation (the “Independent Accounting Firm”), which shall, within twenty (20) business days after such submission, determine and report to Seller and Purchaser its determination of the payment obligation for such remaining disputed items, and such report shall be final, binding and conclusive on the Parties.  In acting under this Agreement, the Independent Accounting Firm shall be entitled to the privileges and immunities of arbitrators.

10

(b)           Purchase Price Adjustment.  The Statement of Inventory Value shall be deemed final for the purposes of this Agreement upon the earlier of (x) the failure of Purchaser to notify Seller of a dispute within fifteen (15) business days after Seller’s delivery of the Statement of Inventory Value to Purchaser or (y) the resolution of all disputes pursuant to this Section 1.8.  If the difference between the Estimated Inventory Value and the final Statement of Inventory Value (the “Inventory Variance”) exceeds two percent (2%) of the Estimated Inventory Value, then within five (5) business days of the Statement of Inventory Value being deemed final, a payment shall be made as follows:

(i)            if the amount of the Inventory Value reflected on the final Statement of Inventory Value is less than the Estimated Inventory Value, then Seller shall pay an amount equal to the Inventory Variance to an account designated by Purchaser by wire transfer in immediately available funds;

(ii)           if the amount of the Inventory Value reflected on the final Statement of Inventory Value exceeds the Estimated Inventory Value, then Purchaser shall pay an amount equal to the Inventory Variance to an account designated by Seller by wire transfer in immediately available funds; or

(iii)          if the Inventory Variance is less than two percent (2%) of the Estimated Inventory Value, no payment shall be made on account of the Inventory Variance.

(c)           Fees for Inventory Review.  The fees and disbursements of the Independent Accounting Firm shall be allocated to Purchaser in the same proportion as (x) the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that are unsuccessfully disputed by Purchaser (as finally determined by the Independent Accounting Firm) bears to (y) the total amount of such remaining disputed items so submitted, and the balance shall be paid by Seller.

1.9          Allocation of Purchase Price.  The Purchase Price shall be allocated in detail among the various Acquired Assets in accordance with this Section 1.9.

(a)           Initial Allocation.  Subject to the adjustments described in this Section 1.9, the Purchase Price shall be allocated among the Acquired Assets as follows:

(i)            the Purchase Price minus the Estimated Inventory Value plus any Assumed Liabilities that are required to be treated as part of the purchase price for federal income tax purposes shall be allocated among the Acquired Assets (other than the Inventory) and the goodwill and going concern value of the Product-Related Business as set forth on Schedule 1.9 (the “Allocation Schedule”); and

(ii)           the Estimated Inventory Value shall be allocated among the Inventory as set forth on the Allocation Schedule.

(b)           Revised Allocation.  Within fifteen (15) days after the determination of the Inventory Value, Seller shall prepare and deliver to Purchaser an amended Allocation Schedule prepared in accordance with Section 1060 of the Code and the regulations thereunder (the “Revised Allocation”) that reflects (i) the Inventory Value, which shall be allocated among the Inventory, and (ii) any adjustments in the allocation of the initial Purchase Price and Assumed Liabilities among the Acquired Assets reasonably necessary to reflect changes in the Acquired Assets between the Agreement Date and the Effective Time.

11

(c)           Milestone Allocations.  Within thirty (30) days after the payment of each Milestone Payment, Seller and Purchaser shall agree on an amended Allocation Schedule (a “Milestone Allocation”) that reflects the payment of the Milestone Payment as additional Purchase Price and allocates such additional Purchase Price among the Acquired Assets in a manner consistent with the provisions of Section 1060 of the Code and the Treasury Regulations thereunder.

(d)           Tax Allocation.  In accordance with Section 1060 of the Code and Treasury Regulations thereunder, Purchaser and Seller agree, unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code, to be bound by the Revised Allocation and Milestone Allocation, to file all Tax Returns (including Internal Revenue Service (“IRS”) Form 8594 and any supplemental or amended IRS Form 8594) in accordance with the aforementioned allocations, and not to take any position inconsistent with the aforementioned allocations in the course of any audit, examination, other administrative or judicial proceeding; provided, however, that the provisions of this Section 1.9(d) shall apply only with respect to, and to the extent of any Tax Returns filed by Seller or Purchaser with a U.S. federal, state or local Tax authority and shall not prevent either Seller or Purchaser from seeking relief from the competent authorities under any treaties providing for avoidance of double taxation.

1.10        Prorations.

(a)           Prorations.  Subject to Sections 1.2 and 1.3 above, all royalties, contract payments, and other prepaid and deferred items relating to the Acquired Assets and Assumed Liabilities shall be prorated between Purchaser and Seller in accordance with the principle that (i) Seller shall be responsible for expenses relating to the manufacture and sale of the Products during the periods prior to the Effective Time and (ii) Purchaser shall be responsible for expenses relating to the manufacture and sale of units of Product during the periods after the Effective Time.

(b)           Timing of Payment.  Any prorations pursuant to this Section 1.10 will, insofar as feasible, be determined and paid on the Closing Date, and the Parties shall agree on a statement setting forth all such prorations as soon as practicable after the Closing.  Final settlement and payment by the appropriate Party of the net amount of prorations owing to the other Party shall occur no later than thirty (30) days after the actual amount becomes known.

1.11        Risk of Loss.  At the Effective Time, title to the Acquired Assets is hereby transferred to Purchaser and Purchaser shall hereafter bear all risk of loss associated with the Acquired Assets and be solely responsible for procuring adequate insurance to protect the Acquired Assets against any such loss.

12
