SECTION 1.2 Purchase Price.

(a) The aggregate amount payable by Purchasers at the Closing for the Bio Companies Shares and the assets of CBM Intellectual Property shall be equal to US $460,000,000 (the “Initial Purchase Price”).

(b) The “Final Purchase Price” shall be an amount equal to the Initial Purchase Price

plus or minus, as applicable,

(i) Working Capital to the extent it exceeds (in which case, the Initial Purchase Price shall be increased) or to the extent it is less than (in which case, the Initial Purchase Price shall be decreased) US $56,000,000 (“Target Working Capital”); provided, however, that there shall be no such increase or decrease unless Working Capital exceeds or is less than, as the case may be, Target Working Capital by more than US $1,000,000, in which case the adjustment required by this clause (i) shall be made on a dollar-for-dollar basis from the first dollar;

minus,

(ii) the Additional Adjustment Amount, if any; provided that the Additional Adjustment Amount shall be deemed to be US $0 unless it exceeds US $500,000, in which case the adjustment required by this clause (ii) shall be made on a dollar-for-dollar basis from the first dollar.

Attached as Section 1.2 of the Bio Companies Disclosure Letter is a schedule setting forth the Company’s good faith, illustrative determination of (i) Working Capital, (ii) any Additional Adjustment Amount and (iii) the Final Purchase Price, in each case as if the Closing Date had been August 31, 2006 and determined in accordance with GAAP (the “Signing Date Adjustment Schedule”). Following the delivery of the Signing Date Adjustment Schedule to Purchasers, the Company will consider such revisions thereto as are reasonably proposed by Purchasers.

(c) In determining the Final Purchase Price, to the extent any components or amounts are not reflected in U.S. dollars, the “spot” or currency market exchange rates as of the date two (2) business days before the Closing Date will be utilized.

SECTION 1.3 Final Purchase Price and Post-Closing Adjustment Amount. Subsequent to the Closing, (i) the Company shall be obligated to make a payment to Lonza America (for itself and as agent for the other Purchasers) to the extent that the Final Purchase Price as finally determined pursuant to Section 1.4 is less than the Initial Purchase Price or (ii) Purchasers shall be obligated to make a payment to the Company (for itself and as agent for the other Sellers) to the extent the Final Purchase Price as finally determined pursuant to Section 1.4 exceeds the Initial Purchase Price. The amount equal to the difference between the Initial Purchase Price and the Final Purchase Price as finally determined pursuant to Section 1.4 is referred to herein as the “Post-Closing Adjustment Amount”. The Post-Closing Adjustment Amount shall be paid pursuant to Section 1.5(b) and (c).

SECTION 1.4 Preparation of the Post-Closing Adjustment Statement.

(a) As soon as practicable on or following the Closing Date, but in no event later than the seventh (7^th) business day following the Closing Date, Purchasers and their Representatives shall conduct a physical count of the Inventory as of the close of business on the

Closing Date. The physical count of such Inventory shall be observed and confirmed by the Company and its Representatives. The results of the physical count of the Inventory, which shall take into account changes in Inventory between the Closing Date and the date on which such physical count is completed, shall be used to prepare the Post-Closing Adjustment Schedule pursuant to paragraph (b) below.

(b) Within thirty (30) days after the Closing Date, Purchasers shall prepare and deliver to the Company a post-Closing purchase price adjustment schedule (the “Post-Closing Adjustment Schedule”) setting forth in reasonable detail Purchasers’ good faith determination of (i) Working Capital, (ii) any Additional Adjustment Amount and (iii) the Final Purchase Price, in each case as of the Closing Date and determined in accordance with GAAP. The Company shall give Purchasers and their Representatives (including their advisors and accountants) such assistance and access to the assets and books and records and relevant personnel of the Company and its Subsidiaries as Purchasers may reasonably request during normal business hours in order to enable Purchasers to prepare the Post-Closing Adjustment Schedule. Following delivery of the Post-Closing Adjustment Schedule, Purchasers shall give the Company and its Representatives (including its advisors and accountants) such assistance and access to the assets and books and records and relevant personnel of Purchasers and the Bio Companies as the Company may reasonably request during normal business hours in order to enable the Company to analyze the Post-Closing Adjustment Schedule.

(c) The Post-Closing Adjustment Schedule shall be final and binding on the parties unless the Company shall, within thirty (30) days following the delivery of the Post-Closing Adjustment Schedule, deliver to Purchasers written notice of objection (the “Objection Notice”) with respect to the Post-Closing Adjustment Schedule. The Objection Notice shall specify in reasonable detail each disputed item on the Post-Closing Adjustment Schedule (each, a “Disputed Item”) and describe in reasonable detail the basis for each Disputed Item, including the data that forms the basis thereof, as well as the amount in dispute. Notwithstanding the delivery of an Objection Notice, the Post-Closing Adjustment Schedule shall be final and binding to the extent any item is not a Disputed Item.

(d) If the Objection Notice is delivered, the parties shall consult with each other with respect to the Disputed Items and attempt in good faith to resolve the dispute. If the parties are unable to reach agreement within fifteen (15) days after delivery of the Objection Notice, either Purchasers or the Company may refer any unresolved Disputed Items to the Independent Accountants. The Independent Accountants shall be directed to render a written report as promptly as practicable and, in any event, within fifteen (15) days after the Independent Accountants’ engagement on the unresolved Disputed Items, within the range of values proposed for each Disputed Item by Purchasers and the Company, and to resolve only those issues of dispute set forth in the Objection Notice. The Independent Accountants shall resolve such issues of dispute on a basis consistent with GAAP, and such resolution shall be final and binding on the parties. The fees and expenses of the Independent Accountants shall be borne by the non-prevailing party if and to the extent that the resolution validates the position of the prevailing party and the Final Purchase Price determined by such resolution is more than one percent (1%) greater or less than the Final Purchase Price proposed by the non-prevailing party. Otherwise,

Purchasers, on the one hand, and the Company, on the other, shall each pay 50% of the fees and expenses of the Independent Accountants.

SECTION 1.5 Closing; Payment of Post-Closing Adjustment Amount.

(c) After the final determination of the Post-Closing Adjustment Amount in accordance with Section 1.4, the Post-Closing Adjustment Amount, if any, shall be paid as follows:

(i) if the Final Purchase Price is greater than the Initial Purchase Price, Purchasers shall pay to the Company (for itself and as agent for the other Sellers) the Post-Closing Adjustment Amount, together with any interest earned on such amount; or

(ii) if the Final Purchase is less than the Initial Purchase Price, the Company (for itself and as agent for the other Sellers) shall pay to Lonza America (for itself and as agent for the other Purchasers) the Post-Closing Adjustment Amount, together with any interest earned on such amount.

(d) Payment of the Post-Closing Adjustment Amount shall be made as soon as practicable, but in no event more than three (3) business days, following the final determination of the Post-Closing Adjustment Amount by wire transfer of immediately available funds to a single account designated in writing at least three (3) business days prior to such payment by the Company or Purchasers, as the case may be, and shall be accompanied by a payment of interest determined by computing simple interest on the Post-Closing Adjustment Amount from the Closing Date to the date of payment at the rate of interest announced publicly by JPMorgan Chase Bank as its “reference rate” (on the basis of a 365-day year).

The foregoing payment by Purchasers shall be, and for all purposes will be considered as, payment on behalf of the Company and in respect of obligations and liabilities of the Company.

(c) The Company represents to Purchasers that upon payment of the amounts set forth in this Section 1.6, the Company and the Bio Companies will not be subject to any further obligations or liabilities with respect to the Credit Agreement or the Pay-Off Amount.

SECTION 1.7 Further Assurances; Post-Closing Cooperation.

(a) Subject to the terms and conditions of this Agreement, at any time or from time to time after the Closing, each of the parties hereto shall execute and deliver such other documents and instruments, provide such materials and information and take such other actions as may reasonably be necessary, proper or advisable, to the extent permitted by Law, to fulfill its obligations under this Agreement.

(b) Following the Closing, each party will afford the other party, its counsel and its accountants, during normal business hours, reasonable access to the books, records, personnel files, payroll files and other data relating to the Bio Companies Business in its possession with respect to periods prior to the Closing and the right to make copies and extracts therefrom, to the extent that such access may be reasonably required by the requesting party in connection with (i) the preparation of Tax Returns, (ii) the determination or enforcement of rights and obligations under this Agreement, (iii) compliance with the requirements of any Governmental Authority, (iv) in connection with any actual or threatened Action or Proceeding, including, but not limited to, the Rubin Litigation or (v) the determination of pension or other benefits.

reasonable efforts to ensure that any employees or personnel of the Bio Companies will appear if called to testify at trial. Further, each party agrees for a period extending seven (7) years after the Closing Date not to destroy or otherwise dispose of any such books, records, personnel files, payroll files and other data unless such party shall first offer in writing to surrender such books, records, personnel files, payroll files and other data to the other party and such other party shall not agree in writing to take possession thereof during the sixty (60) day period after such offer is made. The parties acknowledge and agree that any cooperation and access provided by or on behalf of Purchasers as contemplated in this Section 1.7(b), including but not limited to any cooperation and access provided by Purchasers and their employees and personnel in connection with the Rubin Litigation or any other Company Liability, shall under no circumstances imply that Purchasers, the Bio Companies or their respective Affiliates are assuming or retaining any Liabilities arising out of, resulting from or relating to the Rubin Litigation or such other Company Liability, which Liabilities shall remain obligations of the Company pursuant to the terms of this Agreement.

(c) If, in order properly to prepare its Tax Returns, other documents or reports required to be filed with Governmental Authorities or its financial statements or to fulfill its obligations hereunder, it is necessary that a party be furnished with additional information, documents or records relating to the Bio Companies Business not referred to in paragraph (b) above, and such information, documents or records are in possession or control of the other party, such other party agrees to use its reasonable best efforts to furnish or make available such information, documents or records (or copies thereof) at the recipient’s request, cost and expense.

(e) Any party requesting information pursuant to Section 1.7(b) or (c) shall reimburse the non-requesting party for the reasonable out-of-pocket costs, if any, of creating, gathering, copying and transporting such information.

Each Seller is duly licensed or qualified to do business and is in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased or held under license by it makes such licensing or qualification necessary, except where the failure to be so licensed, qualified or in good standing would not, individually or in the aggregate, reasonably be expected to impair in any material respect the ability of any Seller to perform its obligations hereunder or prevent or materially delay consummation of the Bio Companies Transactions.

(b) Each of the Bio Companies is a corporation or other organization duly organized, validly existing and in good standing under the Laws of the jurisdiction of its incorporation or organization.

Section 2.1(b) of the Bio Companies Disclosure Letter sets forth a true and complete list of the jurisdiction of incorporation or organization of each Bio Company.

(c) The Company has previously made available to Purchasers complete and correct copies of the certificate of incorporation and bylaws (or other comparable organizational documents) of each of the Bio Companies, as amended to the date of this Agreement (the “Bio Companies Charter Documents”).

SECTION 4.2 Other Offers; Etc.

(a) The Company and its Subsidiaries shall, and the Company shall use its reasonable best efforts to cause its and its Subsidiaries’ respective directors, officers, employees and investment bankers (collectively, “Representatives”) to, immediately cease any discussions or negotiations that may be ongoing as of the date of this Agreement with any Person with respect to a Bio Companies Takeover Proposal. During the period from the date of this Agreement until the Closing Date, or such earlier date as this Agreement may be terminated in accordance with its terms, the Company and its Subsidiaries shall not, and the Company shall use its reasonable best efforts to cause its and its Subsidiaries’ Representatives not to, (i) solicit, initiate or knowingly encourage any Bio Companies Takeover Proposal, (ii) participate in any discussions or negotiations with (whether initiated by the Company or not), or furnish any information to, any Person relating to any possible Bio Companies Takeover Proposal, (iii) enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement constituting or related to, or reasonably likely to lead to, any Bio Companies Takeover Proposal (each, a “Bio Companies Acquisition Agreement”), or (iv) make or authorize any statement, recommendation or solicitation to any Person other than the Company in support of any possible Bio Companies Takeover Proposal. Notwithstanding the foregoing, at any time prior to obtaining the Company Stockholder Authorization, (x) the Company and its Representatives may have discussions with any Person that has made an unsolicited Bio Companies Takeover Proposal in order to clarify and understand the terms and conditions of such proposal, (y) the Company may waive the provisions of any “standstill” agreement between the Company and such Person to the extent necessary to permit such Person to submit an unsolicited Bio Companies Takeover Proposal if the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to so waive the applicable provisions of such standstill agreement would not be consistent with the Company Board’s fiduciary duties to the stockholders of the Company under the Laws of the State of Delaware (“Delaware Law”) and (z) if the Company Board (A) receives an unsolicited Bio Companies Takeover Proposal that did not result from a breach of this Section 4.2 and the Company Board determines in good faith (after consultation with outside legal counsel and a financial advisor of nationally recognized reputation) that such unsolicited Bio Companies Takeover Proposal constitutes or would reasonably be expected to lead to a Superior Bio Companies Proposal and (B) determines in good faith (after consultation with outside legal counsel) that the failure to take any of the following actions in response to such Bio Companies Takeover Proposal would not be consistent with its fiduciary duties to the stockholders of the Company under Delaware Law, then the

Company may (x) furnish information with respect to the Bio Companies and the Bio Companies Business to the Person making such Bio Companies Takeover Proposal (provided that the Company shall only provide non-public information pursuant to a confidentiality agreement not less restrictive of the recipient thereof in the aggregate than the Confidentiality Agreement, it being understood that such confidentiality agreement shall not prohibit disclosure to Purchasers of any of the information and materials required to be disclosed or provided to Purchasers pursuant to this Agreement), and (y) participate in discussions and negotiations with such Person regarding such Bio Companies Takeover Proposal and, to the extent reasonably required to evaluate a Bio Companies Takeover Proposal that includes the issuance of securities by the Person making such Bio Companies Takeover Proposal, may enter into a customary confidentiality agreement in order to obtain non-public information with respect to such Person. Without limiting the foregoing, it is understood that any violation of the restrictions set forth in this Section 4.2 by any Representative of the Company or any of its Subsidiaries shall be deemed a breach of this Section 4.2 by the Company.

(b) Except as expressly permitted by this Section 4.2(b), (i) the Company Board and any committee thereof shall not (A) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Purchasers, its recommendation that the holders of Company Common Stock authorize the Bio Companies Transactions (the “Bio Companies Recommendation”) or (B) approve or recommend or propose publicly to approve or recommend to the holders of Company Common Stock, or otherwise permit or cause the Company to accept or enter into, a Bio Companies Takeover Proposal (any action described in this clause (i) being referred to as a “Bio Companies Adverse Recommendation Change”), (ii) neither the Company nor any of its Subsidiaries shall enter into any Bio Companies Acquisition Agreement other than a confidentiality agreement permitted by and subject to the requirements of Section 4.2(a), (iii) neither the Company nor any of its Subsidiaries shall release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which the Company is a party except to the extent the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to so waive the applicable provisions of a standstill agreement would not be consistent with the Company Board’s fiduciary duties to the stockholders of the Company under Delaware Law and (iv) neither the Company Board nor any committee thereof shall agree or resolve to take any actions set forth in clauses (i), (ii) or (iii) of this sentence. Notwithstanding the foregoing or any provision of Section 4.2(a), prior to the Company Stockholder Authorization, (x) other than in connection with a Bio Companies Takeover Proposal, the Company Board may withdraw or modify the Bio Companies Recommendation if it determines in good faith (after consultation with outside legal counsel) that the failure to take such action would not be consistent with its fiduciary duties to the stockholders of the Company under Delaware Law, and (y) subject to Section 4.2(c), if the Company Board (A) receives a Bio Companies Takeover Proposal that it determines in good faith (after consultation with outside legal counsel and a financial advisor of nationally recognized reputation) constitutes a Superior Bio Companies Proposal, and (B) determines in good faith (after consultation with outside legal counsel) that failure to take any of the following actions would not be consistent with its fiduciary duties to the stockholders of the Company under Delaware Law, then the Company Board may (I) make a Bio Companies Adverse Recommendation Change and/or (II) cause the Company to enter into a Bio Companies Acquisition Agreement with respect to such Superior Bio Companies Proposal, but only if the Company shall have concurrently with entering into

such Bio Companies Acquisition Agreement terminated this Agreement pursuant to Section 8.1(c)(i).

(c) If the Company Board determines to effect a Bio Companies Adverse Recommendation Change as provided in Section 4.2(b)(y)(I) or to authorize the Company to enter into a Bio Companies Acquisition Agreement as provided in Section 4.2(b)(y)(II), such Bio Companies Adverse Recommendation Change or Bio Companies Acquisition Agreement (as applicable) may only become effective after the end of the fifth (5^th) business day following Purchasers’ receipt of written notice from the Company (a “Bio Companies Adverse Recommendation Notice”) advising Purchasers that the Company Board intends to effect such Bio Companies Adverse Recommendation Change or to authorize the Company to enter into such Bio Companies Acquisition Agreement, which notice shall contain a copy of the Superior Bio Companies Proposal to which such Bio Companies Adverse Recommendation Change or Bio Companies Acquisition Agreement relates; provided that any material amendment to the terms of such Superior Bio Companies Proposal after the initial Bio Companies Adverse Recommendation Notice shall require a new Bio Companies Adverse Recommendation Notice and restart the five (5) business day period referred to above. In determining whether to effect a Bio Companies Adverse Recommendation Change or to cause the Company to enter into a Bio Companies Acquisition Agreement in response to a Superior Bio Companies Proposal, in each case, as provided in Section 4.2(b)(y), the Company Board shall take into account in good faith any changes to the terms of this Agreement proposed by Purchasers (in response to a Bio Companies Adverse Recommendation Notice or otherwise) in determining whether such Bio Companies Takeover Proposal still constitutes a Superior Bio Companies Proposal.

(d) In addition to the obligations of the Company set forth in Section 4.2(a), (b) and (c), the Company will, unless (and to the extent) the Company Board determines in good faith (after consultation with outside legal counsel) that doing so would not be consistent with its fiduciary duties to the stockholders of the Company under Delaware Law, (i) promptly, and in any event within 24 hours, advise Purchasers orally and in writing of any request for information with respect to a potential Bio Companies Takeover Proposal or of any Bio Companies Takeover Proposal, the financial and other material terms and conditions of such request or Bio Companies Takeover Proposal and the identity of the Person making such request or Bio Companies Takeover Proposal, (ii) keep Purchasers reasonably informed of the status and details (including amendments or proposed amendments) of any and all such requests or Bio Companies Takeover Proposals and (iii) provide to Purchasers as soon as practicable after receipt or delivery thereof (and in any event within 48 hours) copies of all material correspondence and other written material sent or provided to the Company, directly or indirectly, from any third party in connection with any Bio Companies Takeover Proposal or inquiry or sent or provided by the Company to any third party in connection with any Bio Companies Takeover Proposal or inquiry.

SECTION 4.6 Public Announcements. The initial press release to be issued by each of the Company, on the one hand, and Purchasers, on the other, with respect to the execution of this Agreement shall be reasonably agreed upon by Lonza America (for itself and as agent for the other Purchasers) and the Company (for itself and as agent for the Sellers).

Until the Closing Date, the information provided pursuant to this Agreement will be subject to the terms of the Confidentiality Agreement, dated as of April 13, 2006, between Lonza Group and the Company (as it may be amended from time to time, the “Confidentiality Agreement”), which shall survive the termination of this Agreement in accordance with the terms of the Confidentiality Agreement.

(f) With regard to the Debris Field Remediation, the Company and Purchasers shall enter into a mutually satisfactory access agreement.

(g) The first US $500,000 of Remediation Costs incurred by or on behalf of the Company in connection with the Debris Field Remediation obligations under this Section 4.11 shall be paid solely by the Company, the next US $500,000 of Debris Field Remediation Costs incurred by or on behalf of the Company in connection with the Debris Field Remediation obligations under this Section shall be split equally between the Company, on the one hand, and Purchasers, on the other, and all Debris Field Remediation Costs in excess of US $1,000,000 shall be borne by Purchasers; provided that in no event shall the Company or any Seller be responsible for (i) any consequential, incidental or special costs or damages, such as those arising from lost profits or a business interruption, relating to the Debris Field Remediation or (ii) any Remediation Costs or other Losses to the extent that the Remediation Costs or Losses arise from, relate to or are increased or aggravated by the breach of any of Purchasers’ obligations under this Section 4.11.

SECTION 4.17 Insurance.

(a) Purchasers acknowledge and agrees that, upon Closing, all insurance coverage provided in relation to the Bio Companies Business shall cease and no further coverage shall be available to the Bio Companies under any such policies or programs to the extent that such are “claims made” based policies, but (subject to the terms of any relevant policy) without prejudice to any accrued claims which any of the Bio Companies or any Seller, any of their Subsidiaries or Affiliates (in the latter case in relation to the Bio Companies Business) may have made on or prior to Closing under any of such policies; provided that the Bio Companies Business shall retain the benefit of “occurrence” based policies of insurance in relation to events occurring prior to Closing but in respect of which no claim has yet arisen at the time of Closing, it being understood and agreed that the retention by the Bio Companies Business of the benefit of such “occurrence” based policies of insurance shall, to the extent such coverage also exists with respect to the Company or any of its current or former Subsidiaries or Affiliates (other than the Bio Companies), be without prejudice to the rights of the Company or such other current or former Subsidiary or Affiliate to continue to retain the benefit of such “occurrence” based policies of insurance at and after the Closing Date as such policies were in effect on the date prior to the Closing Date.

(b) Purchasers and Sellers agree that any claims made under the insurance policies referred to in Section 4.17(a) in respect of the Bio Companies Business and as to which coverage remains available after Closing shall be administered and collected by Sellers (or by a claims handler appointed by Sellers) on behalf of Purchasers. Purchasers shall cooperate fully with Sellers to enable Sellers to comply with the requirements of the relevant insurer, and Purchasers shall provide such information and assistance as Sellers may reasonably request in connection with any such claim. Without prejudice to the provisions of Sections 9.1 and 9.2, any monies received by Sellers as a result of such claims and not utilized by Sellers prior to the Closing Date to repair the damage, pay the Liability or otherwise resolve the related claim shall be paid over to Purchasers, net of all reasonable costs and expenses of recovery (including, without limitation, all reasonable handling and collection charges by any claims handler appointed by Sellers).

SECTION 4.18 Delivery of Financial Statements. From the date hereof until the Closing, the Company shall deliver to Purchasers unaudited financial statements of the Bioproducts Companies and the Biopharma Companies (a) within fifteen (15) business days after the end of each fiscal month ending after the date of the financial statements delivered pursuant to clauses (iii) and (iv) of Section 2.5(a), monthly financial statements consisting of a balance sheet as of the end of such month and statements of income for that month and for the portion of

The Monthly Financial Statements and the Quarterly Financial Statements shall be prepared on a basis consistent with past practice for the monthly and quarterly interim internal reports of the Bioproducts Companies and the Biopharma Companies. The Annual Financial Statement shall be prepared on a basis consistent with the financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2005 included in the Company SEC Documents.

SECTION 4.19 Termination of Rights; Assignment of Certain Agreements and Rights.

(a) The Sellers agree that, effective as of the Closing, all rights of any of the Sellers and any of their Subsidiaries or Affiliates to directors’ and officers’ indemnification by or from any of the Bio Companies (whether by contract, by-law, Law or otherwise) shall be terminated, void or of no effect and unenforceable by them.

(b) At or prior to the Closing, the Sellers shall, and shall cause their respective Subsidiaries and Affiliates to, use their commercially reasonable efforts to transfer and assign to a Bio Company all of their right, title and interest in and to all of the prior acquisition and indemnity agreements relating to any of the Bio Companies that provide for continuing or available indemnities or payments to or for the benefit of the Bio Companies Business as of the Closing Date, to the extent relating to the Bio Companies Business.

(c) At or prior to the Closing, the Sellers shall, and shall cause their respective Subsidiaries and Affiliates to, use their commercially reasonable efforts to transfer and assign to Purchasers or a Bio Company (other than CBM Intellectual Property) all of the Sellers’ right, title and interest in and to any and all (i) NDAs that provide for continuing or available confidentiality protection for the benefit of, or related to the confidential information of, the Bio Companies or the Bio Companies Business as of or following the Closing Date and (ii) written non-competition, non-solicitation, confidentiality or similar protective covenants or agreements to which any Seller, any Subsidiary of any Seller (excluding the Bio Companies) or any of their respective officers or employees (or former officers or employees) is a party, in each case to the extent such NDA, covenant or agreement relates to or was entered into for the benefit of the Bio Companies or the Bio Companies Business. To the extent any such NDA, covenant or agreement has not been (or under the terms of such NDA, covenant or agreement cannot by its terms be) assigned to Purchasers or a Bio Company, the Company and the other Sellers shall, from and after the date of this Agreement, perform and fully enforce (including not agreeing to any modification, amendment or waiver) and take all actions as may be reasonably requested by Purchasers to prevent the violation or breach by any other party of any such NDA or covenant or

agreement; provided that Purchasers shall reimburse the Company and the other Sellers for the reasonable out-of-pocket costs of any counsel fees and travel and other expenses incurred, after consultation with Purchasers, in connection with their taking any such action.

SECTION 4.20 Non-Competition. During the Restricted Period, the Company shall not, and shall cause its Subsidiaries not to, engage directly or indirectly in any business that competes, directly or indirectly, with the business conducted by the Bio Companies as of the Closing Date in any geographic area in which the Bio Companies conduct that business as of the Closing Date (a “Competing Business”); provided, however, that no owner of less than five percent (5%) of the outstanding stock of any publicly-traded corporation shall be deemed to engage solely by reason thereof in a Competing Business; provided, further, that the provisions of this Section shall not (a) be applicable to any bona fide third party purchaser who acquires all or any substantial portion of the stock or assets of the Company and its Subsidiaries, whether by means of a merger, consolidation, share exchange, business combination or similar transaction, or (b) prohibit the Company or any of its Subsidiaries from acquiring any business if less than 10% of the revenues of such business for its most recently completed fiscal year are attributable to a Competing Business; provided further, however, that in each such case the Company shall not, and shall cause its Subsidiaries not to, provide such third party purchaser or the employees associated with such business with any confidential information of the Bio Companies or the Bio Companies Business. If the final judgment of a court of competent jurisdiction declares that any term or provision of this Section is invalid or unenforceable, the parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed.

SECTION 4.21 Non-Solicitation of Customers and Employees. During the Restricted Period, the Company shall not, and shall cause its Affiliates not to, directly or indirectly, in one or a series of transactions, recruit, solicit or otherwise induce or influence any proprietor, partner, lender, sales agent, joint venturer, investor, lessor, customer, supplier, agent or representative which has a material business relationship with any of the Bio Companies to discontinue, reduce or modify such business relationship with any of the Bio Companies, or (ii) employ or seek to employ any employee of any of the Bio Companies who is then (or was at any time within twelve (12) months prior to the date the Company or any of its Subsidiaries or Affiliates employs or seeks to employ such former employee of the Bio Companies) employed or retained by the Company or any of its Subsidiaries or Affiliates unless such Transferred Bio Companies Employee has been terminated by Purchasers or any of their respective Subsidiaries after the Closing Date. Notwithstanding the foregoing, (a) nothing herein shall prevent the Company and its Subsidiaries from providing a letter of recommendation to an employee or other Person with respect to a future employment opportunity and (b) this Section shall not apply to general solicitations of employment not specifically directed towards employees of the Bio Companies; provided that the provisions of this Section 4.21 shall not be applicable to any bona fide third party purchaser who acquires all or any substantial portion of the stock or assets of the Company and its Subsidiaries, whether by means of a merger, consolidation, share exchange,

business combination or similar transaction; provided further, however, that in each such case the Company shall not, and shall cause its Subsidiaries not to, provide such third party purchaser with any confidential information of the Bio Companies or the Bio Companies Business.

TAX MATTERS

SECTION 6.1 Tax Filings.

(a) (i) Where required by applicable Law, the Company shall include any applicable Bio Companies in, or cause those Bio Companies to be included in, and shall file or cause to be filed, (A) the United States consolidated federal income Tax Returns of the Company for all taxable periods of any applicable Bio Company ending on or prior to the Closing Date, and (B) all other Company consolidated, combined or unitary Tax Returns that include one or more of the Bio Companies for all taxable periods ending on or prior to the Closing Date. The Company shall pay (or cause to be paid) all Taxes attributable to the Tax periods for which the Tax Returns referred to in clauses (A) and (B) above are filed. Within 120 days after the Closing Date (or sooner if reasonably requested by the Company to timely file a Tax Return), Purchasers shall cause each of the Bio Companies included in a Tax Return described in clause (A) or

(B) above to prepare and provide to the Company a package of Tax information materials, including schedules and work papers, required by the Company to enable the Company to prepare and file all Tax Returns (which have not been filed on or before the Closing Date) required to be prepared and filed by the Company pursuant to this paragraph (the “Tax Package”). In addition, on or before the earlier of the date that is thirty (30) days after the Closing Date and the fifth (5^th) business day after the calendar quarter in which the Closing occurs, Purchasers shall cause each of the Bio Companies included in a Tax Return described in clause (A) or (B) above to prepare and provide to the Company a package of Tax information materials, including schedules and work papers, required by the Company in connection with the public release of its results of operations for such quarter in a manner consistent with past practice.

(ii) Prior to the Closing, the Company shall prepare and file, or cause to be prepared and filed, all Tax Returns of or which include any Bio Company, other than Tax Returns described in Section 6.1(a)(i), that are required to be filed (after giving effect to any valid extension of time in which to make such filing) on or prior to the Closing Date. The Company shall cause the Bio Companies to pay all Taxes attributable to the Tax periods for which such Tax Returns are filed.

(iii) After the Closing, Purchasers shall prepare and file, or cause to be prepared and filed, on behalf of the Bio Companies all other Tax Returns of, or which include, a Bio Company (other than those Tax Returns described in Section 6.1(a)(i) or Section 6.1(a)(ii)). Purchasers shall, or shall cause the Bio Companies to, pay (or cause to be paid) all Taxes attributable to the Tax periods for which such Tax Returns are filed.

(b) All Tax Returns described in Section 6.1(a) (including the Tax Package) shall be prepared in a manner consistent with past practice unless a past practice has been finally determined to be incorrect by the applicable Taxing Authority or a contrary treatment is required by applicable Tax Laws (or the judicial or administrative interpretations thereof).

(c) To the extent permitted by applicable Law or administrative practice of any Taxing Authority, any transactions involving any of the Bio Companies that are not in the ordinary course of business occurring on the Closing Date but after the Closing, other than any transactions relating to the sale of any Bio Company or any assets thereof to Purchasers or any of Purchasers’ Affiliates, shall be reported on Purchasers’ consolidated United States federal income Tax Return to the extent permitted by Treasury Regulation §1.1502-76(b)(1)(ii)(B) or on the post-Closing separate company Tax Returns of the applicable Bio Company (if the applicable Bio Company does not file a consolidated federal income Tax Return with Purchasers), and shall be similarly reported on all other Tax Returns of Purchasers or its Affiliates to the extent permitted. The Sellers, Purchasers and the Bio Companies shall not take any position inconsistent with the preceding sentence on any Tax Return.

(d) Purchasers and the Company agree to furnish or cause to be furnished to each other, and each at its own expense, as promptly as practicable, such information (including access to books and records) and assistance, including making employees available on a mutually convenient basis to provide additional information and explanations of any material provided relating to the Bio Companies, as is reasonably necessary for the filing of any Tax

Returns, for the preparation for any audit and for the prosecution or defense of any Action or Proceeding relating to any adjustment or proposed adjustment with respect to Taxes. Purchasers shall retain in their possession or cause the Bio Companies to retain in their possession, and shall provide the Company reasonable access to (including the right to make copies of), such supporting books and records and any other materials that the Company may specify with respect to matters relating to Taxes for any taxable period ending on or prior to or which includes the Closing Date for a period of seven (7) years after the Closing Date or such longer period as may be required by Law. After such time, Purchasers may dispose of such material; provided, that prior to such disposition Purchasers shall give the Company a reasonable opportunity at its expense to take possession of such materials.

(e) No Purchasers or any Affiliate or successor of any Purchaser shall (or shall cause or permit any of the Bio Companies to) amend, refile or otherwise modify any Tax Return relating in whole or in part to any Bio Company with respect to any taxable year or period ending on or before December 31, 2005, without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.

SECTION 6.2 Certain Other Taxes. All transfer, documentary, sales, use, stamp, registration and other such similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement, if any, shall be paid 50% by Purchasers and 50% by the Company, and the party obligated under applicable Law to file all necessary Tax Returns and other documentation with respect to any such transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees, shall file such Tax Returns or other documentation and, if required by applicable Law, the other party will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation and will cooperate with the other party to take such commercially reasonable actions as will minimize or reduce the amount of such Taxes or fees.

SECTION 6.3 Tax Audits.

(a) The Company shall have the right (but not the obligation) to represent the interests of the Bio Companies in and control the conduct of any audit or administrative or court Action or Proceeding, with the participation of Purchasers at Purchasers’ expense, relating to Taxes described in Section 6.1(a)(i) and (ii) (a “Tax Claim”) and the Company shall have the right to employ counsel of its choice at its expense in the conduct of any such contest. Purchasers will reasonably cooperate, and shall cause the Bio Companies to reasonably cooperate, at the Company’s expense, with the Company and its counsel in the defense against or compromise of any claim in any said Action or Proceeding. If the Company does not elect to control a Tax Claim pursuant to this Section 6.3(a) that relates to a separate company Tax of a Bio Company and not a Tax relating to a consolidated, combined or unitary Tax Return that includes the Company or a non-Bio Company Subsidiary of the Company, Purchasers or the Bio Companies may, without affecting its or any other indemnified party’s rights to indemnification under this Article VI, assume and control the defense of such Tax Claim with participation by the Company (at the Company’s expense).

(b) If any Taxing Authority asserts a claim, makes an assessment or otherwise disputes any Taxes for which the Company may have an indemnity obligation pursuant to

Section 6.4(a), Purchasers shall, promptly upon receipt by Purchasers and/or the Bio Companies of notice thereof, inform the Company thereof. The failure of Purchasers or the Bio Companies to timely forward such notification in accordance with the immediately preceding sentence shall not relieve the Company of any indemnity obligation it may have pursuant to Section 6.4(a) except and to the extent that the failure to timely forward such notification actually prejudices the ability of the Company to contest such liability for Taxes or increases the amount of such Taxes.

(c) The Company shall have the right, but not the obligation, to jointly represent the interests of any Bio Company with Purchasers in any audit or administrative or court Action or Proceeding relating to Taxes for any Straddle Period. Any disputes regarding the conduct or resolution of any such audit or proceeding shall be resolved pursuant to Section 6.5.

(d) Purchasers shall have the sole right to represent the interests of the Bio Companies in all audits or administrative or court Actions or Proceedings relating to Taxes other than those specified in Section 6.3(a) and (c).

(e) The Company, on the one hand, and Purchasers and/or the Bio Companies, on the other hand, shall not enter into any compromise or agree to settle any claim pursuant to any Tax audit or Action or Proceeding which would adversely affect the other party without the written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed.

SECTION 6.4 Indemnification.

(a) After the Closing Date, the Company shall, to the fullest extent permitted by applicable Law, indemnify and hold harmless Purchasers and the Bio Companies from and against any and all claims, actions, causes of action, liabilities, losses, damages, and reasonable out-of-pocket expenses and costs (“Tax Losses”) resulting from, arising out of or relating to (i) any Taxes that the Company is responsible to pay pursuant to Section 6.1(a)(i) or (ii), (ii) Taxes of any Bio Company with respect to taxable periods ending on or before the Closing Date, and (iii) the Company’s share of Taxes payable pursuant to Section 6.2; provided, however, that the Company shall not be liable pursuant to this Section 6.4 to the extent of Taxes with respect to which a liability was recorded on the Bioproducts Balance Sheet or Biopharma Balance Sheet made available pursuant to Section 2.5(a) and Tax liabilities taken into account in determining Working Capital for purposes of Article I of this Agreement, (iv) any liability for Taxes resulting directly from making any Section 338 Election, provided such election is made in accordance with Section 6.7, and (v) any liability for Taxes (other than Taxes described in Section 6.2 of this Agreement) imposed on any Bio Company arising a result of the transactions contemplated by this Agreement. The indemnity provided in the foregoing sentence shall include, without limitation, any Tax liability arising by reason of any Bio Company being severally liable for any Taxes of another Person pursuant to Treasury Regulation §1.1502-6 or any analogous state, local or foreign Tax provision, as a transferee or successor, by contract or otherwise. For the avoidance of doubt, the Company’s obligation to indemnify Purchasers pursuant to this Section 6.4(a) is unconditional and not subject to any limitation on the Company’s obligations pursuant to Article IX or any other provision of this Agreement.

(b) After the Closing Date, Purchasers shall, to the fullest extent permitted by applicable Law, indemnify and hold harmless the Company and its Affiliates from and against any and all Tax Losses arising out of or relating to (i) any Taxes of the Bio Companies (including Purchasers’ shares of Taxes payable pursuant to Section 6.2) other than amounts for which the Company has an indemnification obligation pursuant to Section 6.4(a) and (ii) any Taxes resulting from Purchasers’ breach of Section 6.7(a).

(c) For purposes of Sections 6.4(a) and (b), whenever it is necessary to determine the liability for Taxes in the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), (i) real, personal and intangible property Taxes (“Property Taxes”) of the Company and its Subsidiaries allocable to periods ending on or prior to the Closing Date (the “Pre-Closing Tax Period”) shall be equal to the amount of such Property Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Tax Period and the denominator of which is the number of days in the Straddle Period; and (ii) Taxes (other than Property Taxes) allocable to the Pre-Closing Tax Period shall be computed as if such taxable period ended as of the close of business on the Closing Date, provided that exemptions, allowances or deductions that are calculated on an annual basis (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and the period after the Closing Date in proportion to the number of days in each period.

(d) Notwithstanding any other provision of this Agreement to the contrary, the indemnification obligations of the parties under this Section 6.4 shall survive until the expiration of the applicable statute of limitations.

SECTION 6.5 Dispute Resolution. In the event that the Company or any Purchaser disputes the application or interpretation of any provision of Sections 6.1 through 6.3, or the amount or calculation of Taxes, if any, owed by such party thereunder, such party shall deliver to the other a statement setting forth, in reasonable detail, the nature of and dollar amount of any disagreement so asserted. The parties shall attempt in good faith to resolve any such dispute within twenty (20) days following the date of the statement provided pursuant to the preceding sentence. If the parties are unable to resolve such dispute within such twenty (20) day period, the dispute shall be resolved by the Independent Accountants. The Independent Accountants shall finally and conclusively resolve any dispute relating to matters set forth in this Section 6.5 within thirty (30) days following receipt of the submission. The Independent Accountants shall determine, only with respect to the specific disagreements submitted in writing by the Company and the applicable Purchaser, the manner in which such item or items in dispute should be resolved; provided, however, that the dollar amount of any such item or items shall be determined within the range of dollar amounts proposed by the Company, on the one hand, and Purchaser, on the other hand. Any finding by the Independent Accountants shall be a reasoned award stating the findings of fact and conclusions of Law (if any) on which it is based, shall be final and binding upon the parties and shall be the sole and exclusive remedy between the parties regarding the disputed items so presented. The fees and expenses of the Independent Accountants shall be shared by the Company and the applicable Purchaser in proportion to each party’s respective liability for Taxes which are the subject of the dispute as determined by the

Independent Accountants, and the parties shall otherwise bear their own expenses incurred in any dispute resolution pursuant to this Section.

SECTION 6.6 Refunds.

(a) Any refunds (including but not limited to any refunds related to the U.K. Group Relief process) of Taxes (together with any interest received with respect thereto) paid to or in respect of the Bio Companies (including any amounts credited against income Tax to which any Purchaser, its Affiliates or any of the Bio Companies becomes entitled) and that relate to Taxes for which the Company is responsible pursuant to this Article VI shall be for the account of the Company. A Purchaser shall pay over to the Company any such refund or the amount of any such credit (in each case, together with any interest received with respect thereto) within fifteen (15) days after receipt or entitlement thereto. The preceding sentences shall not apply to any refunds or credits to the extent such refunds or credits are (i) reflected as an asset on the Bioproducts Balance Sheet or the Biopharma Balance Sheet or (ii) reflected as an asset in determining Working Capital for purposes of Section 1.2 of this Agreement, in each case, all of which refunds or credits shall be for the account of the applicable Purchaser.

(b) Purchasers shall, if the Company so requests and at the Company’s expense, prepare, execute and file any claims for refunds or credits, or cause the Bio Companies to prepare, execute and file any claims for refunds or credits, to which the Company is entitled under this Section. Purchasers shall permit the Company to control the prosecution of any such refund. Notwithstanding the foregoing, Purchasers shall have no obligations under this Section 6.6(b) to the extent Purchasers reasonably determine that fulfilling their obligations described herein would have a material adverse effect on Purchasers with respect to any taxable periods beginning after the Closing Date.

SECTION 6.7 Certain Elections and Other Tax Matters.

(a) Upon the mutual agreement of the Company and Lonza America (for itself and on behalf of the other Purchasers), the Company and Purchasers shall make or join in making any elections under Section 338 of the Code (and any comparable election under any relevant state or local Law) (a “Section 338 Election”) with respect to the purchase and sale of any of the Bio Companies under this Agreement. In no event shall either party make a Section 338 Election with respect to any Bio Company without the prior written consent of the other party. If either party desires to make one or more Section 338 Elections, it shall notify the other party in writing of such decision within sixty (60) days after the Closing Date. If such other party agrees to make the Section 338 Election, the party proposing the Section 338 Election shall propose an allocation of the Final Purchase Price (which, for this purpose, shall include any Bio Company liabilities properly taken into account for purposes of determining the purchase price under Code Section 338) among the assets of the applicable Bio Company in accordance with Code Section 1060 and the Treasury Regulations promulgated thereunder (and any similar provision of state, local or foreign Law, as appropriate), and shall notify the other party in writing of such proposed Final Purchase Price allocation within fifteen (15) days following receipt of the other party’s written consent to the making of such Section 338 Election. The parties shall cooperate in good faith to agree on an allocation of the Final Purchase Price and, once agreed to, the allocation shall be binding on the parties (the “Allocation”). If the parties

cannot agree upon the Allocation within thirty (30) days following the delivery of the proposed allocation then no such Section 338 Election shall be made. Purchasers and the Company shall report and file Tax Returns (including but not limited to Internal Revenue Service Form 8594 if applicable) in all respects and for all purposes consistent with the Allocation. Neither Purchasers nor the Company shall take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with the Allocation unless required to do so by applicable Law. Within 180 days following the Closing, the Company shall deliver to Purchasers IRS Form 8023 (or applicable successor form) for each Bio Company for which a Code Section 338(h)(10) election is made, fully executed by the Company or other applicable sellers pursuant to the requirements stated therein.

(b) Purchasers shall not permit the Bio Companies to carry back any loss, deduction or credit to any taxable period that ends on, prior to or which includes the Closing Date.

(c) It is the intention of the parties to treat any indemnity payment made under this Article VI as an adjustment to the Final Purchase Price for all federal, state, local and foreign Tax purposes, and the parties agree to file their Tax Returns accordingly.

(d) At least five (5) business days prior to the Closing, the Company shall deliver to Purchasers a schedule setting forth the allocation of the Final Purchase Price among the Bio Companies. If any Purchaser disagrees with the allocation of the Final Purchase Price among the Bio Companies, such Purchaser shall notify the Company of such disagreement and its reasons for so disagreeing, in which case the Company and Purchasers shall cooperate in good faith to resolve the disagreement. To the extent the Company and Purchasers cannot agree on a mutually acceptable determination and/or allocation of the Final Purchase Price, such determination and/or allocation shall be made by each of Purchasers, on the one hand, and the Company, on the other, in connection with their respective U.S. federal, state, and local tax returns and other filings, and each such Person shall report the allocation of the Final Purchase Price among the Bio Companies as such party acting in good faith deems appropriate.

(e) If the transfer of any Bio Company is treated as an “applicable asset acquisition” within the meaning of Code Section 1060 (other than any such transfer for which a Section 338 Election is made, the allocation for which shall be governed by Section 6.7(a) hereof) and the Company and Purchasers have agreed on an allocation of the Final Purchase Price to the interests in such Bio Company pursuant to
Section 6.7(d), then, within ninety (90) days after the Closing Date, Purchasers shall deliver to the Company a schedule allocating the portion of the Final Purchase Price allocable to each Bio Company the sale of which is treated as an applicable asset acquisition (such portion determined pursuant to Section 6.7(d) and increased to take into account any Bio Company liabilities properly included therein) among the assets of the applicable Bio Company in accordance with Code Section 1060 and the Treasury Regulations promulgated thereunder (and any similar provision of state, local or foreign Law, as appropriate). If the Company disagrees with any items reflected on the schedule so provided, the Company shall notify Purchasers of such disagreement and its reasons for so disagreeing, in which case the Company and Purchasers shall cooperate in good faith to resolve the disagreement. To the extent the Company and Purchasers cannot agree on the contents of the

schedule delivered pursuant to this Section 6.7(e), each of the Company and Purchasers shall be free to use their own allocation schedule in preparing their respective U.S. federal, state, local and foreign tax returns and other filings. If the parties are able to agree on an allocation for purposes of this Section 6.7(e), Purchasers and the Company shall report and file Tax Returns (including but not limited to Internal Revenue Service Form 8594 if applicable) in all respects and for all purposes consistent with the allocation and neither Purchasers nor the Company shall take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with the allocation unless required to do so by applicable Law. To the extent consistent with the foregoing, any adjustment to the Final Purchase Price shall be allocated as provided by Treasury Regulation §1.1060-1(c).

SECTION 6.8 Certificate of Non-Foreign Status. At the Closing, each Seller that is not a foreign Person for purposes of Code Section 1445 shall deliver to Purchasers, in a form reasonably satisfactory to Purchasers, a certificate from the Seller certifying as to its non-foreign status that complies with Treasury Regulations section 1.1445-2(b)(2).

SECTION 6.9 Termination of Tax Sharing Agreements. Anything in any other agreement to the contrary notwithstanding, all liabilities and obligations between Sellers or any of their Affiliates, on the one hand, and the Bio Companies, on the other hand, under any Tax allocation or Tax sharing agreement in effect prior to the Closing Date (other than this Agreement) shall cease and terminate as of the Closing Date and the Bio Companies shall have no liability or obligation thereunder after the Closing Date.

ARTICLE VII

EMPLOYEE AND BENEFITS MATTERS

SECTION 7.1 Transferred Bio Companies Employees.

(a) Continued Employment. The Bio Companies shall continue to employ immediately following the Closing each of the individuals employed by the Bio Companies immediately prior to the Closing , including, without limitation, any individual on leave or short-term or long-term disability (each such employee being hereafter referred to as a “Transferred Bio Companies Employee”). No provision of this Agreement shall be construed as limiting the ability of Purchasers to terminate the employment of any Transferred Bio Companies Employee at any time following the Closing for any reason, nor shall they be construed to create any contractual rights between any Transferred Bio Companies Employee and Purchasers.

(b) Continued Compensation and Benefits. Without limiting any of the obligations of Purchasers set forth in this Article VII and subject to Section 7.2(a), effective as of the Closing, Purchasers shall continue or establish, or cause to be continued or established, employee compensation and benefit plans, programs, policies and arrangements (including fringe benefits and severance pay) that will provide benefits and compensation to the Transferred Bio Companies Employees (and, if applicable, their eligible beneficiaries) for a period of at least one (1) year after the Closing (or such longer period as may be required by applicable Law) that are at least substantially comparable in the aggregate to those provided by the Company and its Subsidiaries (including the Bio Companies) to the Transferred Bio Companies Employees (and,

if applicable, their eligible beneficiaries) immediately prior to the Closing. Without limiting the foregoing, Purchasers and their respective Affiliates shall (i) honor all employment, severance, retention and change-in-control agreements by and between the Company or its Subsidiaries and any Transferred Bio Companies Employee or any Former Bio Companies Employee, which agreements shall be assigned to, and assumed by, Purchasers or a Bio Company on or prior to the Closing Date, (ii) for the longer of one (1) year following the Closing and the period during which such benefits are required to be provided by the terms of any applicable Company Plan, continue to maintain for each Transferred Bio Companies Employee the severance arrangements maintained by the Company or any of its Subsidiaries (including the Bio Companies) for each such Transferred Bio Companies Employee immediately prior to the Closing and (iii) assume and perform the obligations of the Company with respect to Transferred Bio Companies Employees and Former Bio Companies Employees under The Cambrex Corporation 2004 Incentive Plan in accordance with the terms of such plan as in effect on the date hereof.

(c) Service Crediting, Etc. For purposes of vesting, eligibility to participate and level of benefits (but not benefit accrual under pension or similar plans and not for purposes of eligibility for any post-retirement medical benefits) under the employee benefit plans of Purchasers and their respective Affiliates which provide benefits to any Transferred Bio Companies Employees after the Closing (the “New Plans”), each Transferred Bio Companies Employee shall be credited with his or her years of service with the Company and its Subsidiaries (including the Bio Companies) before the Closing, to the same extent as such Transferred Bio Companies Employee was entitled, before the Closing, to credit for such service under the corresponding Bio Companies Plan in which such Transferred Bio Companies Employee participated or was eligible to participate immediately prior to the Closing; provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits or to the extent that prior service with a Purchaser and its Affiliates is not provided under such Purchaser Plan for similarly situated employees of Purchasers and its Affiliates who is not a Transferred Bio Companies Employee. In addition, and without limiting the generality of the foregoing but subject to the consent of any applicable insurer or other service provider with respect to a New Plan: (i) each Transferred Bio Companies Employee shall be immediately eligible to participate, without any waiting time, in each New Plan that is an employee welfare benefit plan (within the meaning of section 3(1) of ERISA) to the extent that the Transferred Bio Companies Employee had satisfied the waiting period under a corresponding Bio Companies Plan in which such Transferred Bio Companies Employee participated immediately before the Closing and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Transferred Bio Companies Employee, a Purchaser or its Affiliates shall cause (x) all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless such conditions would not have been waived under the corresponding Bio Companies Plan in which such employee participated immediately prior to the Closing, and (y) any eligible expenses incurred by such employee and his or her covered dependents during the portion of the plan year of the applicable Bio Companies Plan ending on the date such employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

SECTION 7.2 Treatment of Certain Plans and Coverages.

(a) Company Pension Plans. Notwithstanding anything to the contrary contained in this Article VII, but subject to Section 7.3(a), neither Purchasers nor any of the Bio Companies shall have any responsibility for, or liability under or with respect to, The Retirement Plan for Employees of Cambrex Corporation, The Cambrex Corporation Savings Plan, The Cambrex Retiree Medical Plan or the Cambrex Non-Qualified Deferred Compensation Plan (collectively, the “Company Pension Plans”), and the Company Pension Plans shall each retain all assets and liabilities related to Transferred Bio Companies Employees and Former Bio Companies Employees accrued thereunder. Each Purchaser, its Affiliates and their assigns shall cooperate with the Company and its successors and assigns in connection with administering the benefits accrued by Transferred Bio Companies Employees and Former Bio Companies Employees under the Company Pension Plans and to promptly provide all documentation, information and assistance reasonably requested by the Company, its successors and assigns or the administrator of the Company Pension Plans in respect of the administration and or distribution of such benefits. The Company and its Affiliates (other than the Bio Companies) shall indemnify and hold Purchasers and the Bio Companies and their respective Affiliates harmless against all Liabilities related to the Company Pension Plans, regardless of when such Liabilities arise.

(b) Bio Companies Pension Plans. Subject to Section 7.2(a), each deferred compensation, pension, retirement or other similar plan that covers or provides benefits solely to Transferred Bio Companies Employees and/or Former Bio Companies Employees, including, without limitation, the BioWhittaker, Inc. Supplemental Executive Retirement Plan (the “Bio Companies SERP”) and the Non-Qualified Deferred Compensation Plan (collectively, the “Bio Companies Stand-Alone Pension Plans”), shall be sponsored by a Bio Company as of the Closing (and any associated insurance and service provider agreements shall have been assumed by a Bio Company as of the Closing), and the Company shall have caused to be transferred to the applicable Bio Companies sponsorship of any trust established to fund any Bio Companies Stand-Alone Pension Plan. The Company, its Affiliates and their assigns shall provide reasonable cooperation to Purchasers, the Bio Companies and their successors and assigns in connection with administering the Bio Companies Stand-Alone Pension Plans and shall as soon as reasonably practicable provide all documentation, information and assistance reasonably requested by Purchasers, the Bio Companies, their successors and assigns or the administrator of the Bio Companies Stand-Alone Pension Plans in respect of the administration of and/or distribution of benefits from such plans. Purchasers and the Bio Companies shall (i) within thirty (30) days following the Closing, make any contribution required to be made pursuant to section 4.4 of the Bio Companies SERP and (ii) indemnify and hold the Company and its Affiliates harmless against all Liabilities related to the Bio Companies Stand-Alone Pension Plans, regardless of when such Liabilities arise.

(c) Flexible Spending Accounts. Purchasers or an Affiliate of Purchasers shall establish flexible spending accounts for medical and dependent care expenses under a new or existing plan established or maintained under Section 125 or Section 129 of the Code, as applicable (“Purchasers FSAs”), effective as of the Closing Date, for each Transferred Bio Companies Employee who, as of the Closing Date, is a participant in a flexible spending account

for medical or dependent care expenses under a Bio Companies Plan pursuant to Section 125 or Section 129 of the Code (“Company FSAs”). As soon as administratively practicable following the Closing Date, the Company shall provide an accounting to Purchasers of each applicable Transferred Bio Companies Employee’s account balance in Company FSAs, in each case as of the Closing Date. Upon receipt of such accounting, Purchasers shall cause each participating Transferred Bio Companies Employee’s account under Purchasers FSAs to be credited or debited, as applicable, effective on the day after the Closing Date, in an amount equal to the applicable account balance of such Transferred Bio Companies Employee under the corresponding Company FSA as of the Closing Date. As soon as administratively practicable after the delivery of the accounting described above, the Company shall transfer to Purchasers an amount equal to the total contributions made to Company FSAs by Transferred Bio Companies Employees in respect of the plan year in which the Closing Date occurs, reduced by an amount equal to the total claims already paid to Transferred Bio Companies Employees under such plans in respect of such plan year; provided that if such amount is a negative number, Purchasers shall transfer to the Company, within thirty (30) days following the Company’s request, an amount equal to the aggregate deficit balance in such accounts. Purchasers and the Company intend that the actions to be taken pursuant to this Section be treated as an assumption by Purchasers of the portion of Company FSAs and the elections made thereunder attributable to the participating Transferred Bio Companies Employees.

(d) COBRA Coverage. Purchasers shall, commencing on the Closing Date, provide group health plan continuation coverage pursuant to Section 4980B of the Code and Sections 601 through 609 of ERISA (together with the regulations promulgated thereunder, “COBRA Coverage”) to each Transferred Bio Companies Employee (and such employee’s eligible dependents) who is receiving, or is eligible to receive, COBRA Coverage on the Closing or becomes eligible for COBRA Coverage following the Closing.

SECTION 7.3 Treatment of Certain Liabilities.

(a) Post-Termination Welfare Benefits. Purchasers and the Bio Companies shall assume responsibility for, and shall indemnify and hold the Company and its Affiliates harmless against, all Liabilities related to the obligation to provide any post-termination welfare benefits (including, without limitation, long-term disability and post-retirement medical, dental, vision, pharmacy and life insurance benefits) under the Cambrex Retiree Medical Plan to any eligible Transferred Bio Companies Employee or Former Bio Companies Employee at the Rockland facility (and, if applicable, his or her eligible beneficiaries) who has satisfied the eligibility conditions for such benefits as of the Closing and who elects such coverage within thirty (30) days following the Closing.

(b) Other Liabilities. Except as set forth in Section 7.2(a) and Section 7.2(c), Purchasers and the Bio Companies shall assume, discharge, pay and be solely liable for, and shall indemnify and hold the Company and its Subsidiaries harmless from and against, any and all Losses related to Transferred Bio Companies Employees or Former Bio Companies Employees including, without limitation, (i) any earned and unused vacation, holiday pay or other fringe benefits, (ii) any health, accidental death and dismemberment, disability or life insurance coverage and any health and welfare benefits under the Bio Companies Plans, (iii) any

severance pay, salary continuation, retention or other special bonuses or like compensation payable under the Bio Companies Plans, including without limitation, to the extent not paid prior to Closing, accrued bonuses payable on a discretionary basis to employees of the Biopharma Companies in an amount equal to the amounts reserved therefor in the financial statements delivered by the Company to Purchasers pursuant to Section 2.5(a)(iv) and (iv) any other Liability arising out of the employment or termination of employment of the Transferred Bio Companies Employees or Former Bio Companies Employees, in each case whether such Losses relate to or arise out of events, occurrences, actions, omissions, facts or circumstances occurring, existing or asserted before, on or after the Closing Date. Purchasers shall make all necessary arrangements to assume all worker’s compensation claim files, whether open or closed, as of the Closing Date, and will make the necessary arrangements for assuming the continued management of such liabilities, including through providing to the Company at Closing a letter of credit in favor of the Company.

SECTION 7.4 No Plan Amendments; No Third Party Beneficiaries; Non-US Law.

(a) No provision of this Agreement is intended to be, and shall not be construed as, an amendment of an employee benefit plan, program, policy or arrangement nor shall any provision of this Agreement be interpreted to modify, waive or supplement the provisions of any employee benefit plan, program, policy or arrangement.

(b) It is understood and agreed between the parties that all provisions contained in this Agreement with respect to employee benefit plans or employee compensation are included for the sole benefit of the respective parties hereto and do not and shall not create any right in any other person, including, but not limited to, any Transferred Bio Companies Employees or Former Bio Companies Employee, any participant in any benefit or compensation plan or any beneficiary thereof.

(c) Notwithstanding any other provision of this Agreement, Purchasers and Sellers shall (or shall cause their respective Affiliates to) take all commercially reasonable actions necessary to cause the transfer of employment of each Transferred Bio Companies Employee whose employment is governed by a jurisdiction other than the United States from employment with the Seller to employment with Purchasers (or their respective Affiliates) and the Seller and Purchasers agree that all such transfers of employment shall be made in all respects in accordance with the applicable requirements of local Law.

(a) by the mutual written consent of the Company and Purchasers; or

(b) by either the Company or Purchasers:

(i) if any Restraint having any of the effects set forth in Section 5.1(b) shall be in effect and shall have become final and non-appealable; provided that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available to a party if the issuance of such final, non-appealable Restraint was primarily due to the failure of such party to perform any of its obligations under this Agreement;

(ii) if the Closing shall not have been consummated on or before the Outside Date; provided that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to any party whose failure to perform any of its obligations under this Agreement resulted in the failure of the Closing to be so consummated on or before the Outside Date; or

(i) the Company enters into a definitive Bio Companies Acquisition Agreement providing for a Superior Bio Companies Proposal; provided, however, that the Company may only exercise this termination right if the Company has complied with its obligations under Section 4.2, including, without limitation, Section 4.2(c); and provided, further, that such termination shall not be effective unless concurrently therewith the Company fulfills its obligations under Section 8.3;

(ii) any of the representations and warranties of Purchasers set forth in this Agreement shall not be true and correct on and as of the date of such determination as if made on such date (other than those representations and warranties that address matters only as of a particular date which shall be true and correct as of such date), but only to the extent that such failure would cause the condition contained in Section 5.3(a) not to be satisfied as of such date and such condition is, as a result of any such failure, incapable of being satisfied on or before the Outside Date; or

(iii) Purchasers shall have breached or failed to perform or comply with any obligation, agreement or covenant required by this Agreement to be performed or complied with by it, but only to the extent that such breach or failure would cause the condition contained in Section 5.3(b) not to be satisfied as of such date and such condition is, as a result of any such failure, incapable of being satisfied on or before the Outside Date.

(d) by Purchasers, if:

that address matters only as of a particular date, which shall be true and correct as of such date), but only to the extent that such failure would cause the condition contained in Section 5.2(a) not to be satisfied as of such date and such condition is, as a result of such breach or failure, incapable of being satisfied on or before the Outside Date;

(ii) the Company shall have breached or failed to perform or comply with any obligation, agreement or covenant required by this Agreement to be performed or complied with by it, but only to the extent that such breach or failure would cause the condition contained in Section 5.2(b) not to be satisfied as of such date and such condition is, as a result of such breach or failure, incapable of being satisfied on or before the Outside Date;

(iii) a Bio Companies Adverse Recommendation Change shall have occurred;

(iv) an event has occurred or a circumstance exists that could reasonably be expected to have a Bio Companies Material Adverse Effect, but only to the extent that such event or circumstance would cause the condition contained in Section 5.2(c) not to be satisfied as of such date and such condition is, as a result of such event or circumstance, incapable of being satisfied on or before the Outside Date; or

(v) the Company Board or any committee thereof shall have (A) failed to recommend the Bio Companies Transactions to the holders of Company Common Stock in accordance with this Agreement, (B) withdrawn or modified or proposed publicly to withdraw or modify in a manner adverse to Purchasers its approval or recommendation of this Agreement or the Bio Companies Transactions, (C) approved or recommended, or proposed publicly to approve or recommend, a Bio Companies Takeover Proposal to the holders of Company Common Stock, (D) caused the Company or its Subsidiaries or their respective Representatives to take any action that would constitute a breach of Section 4.2, (E) caused any Seller or Bio Company to enter into a Bio Companies Acquisition Agreement, or (F) resolved to take any of the foregoing actions.

SECTION 8.2 Effect of Termination. In the event of the termination of this Agreement by either party as provided in Section 8.1, written notice thereof shall be given to the other party, specifying the provision hereof pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than Sections 4.9, 8.2, 8.3, 10.1, 10.2, 10.3, 10.6, 10.7, 10.8, 10.9, 10.10, 10.12, the penultimate sentence of Section 4.7 and the Confidentiality Agreement in accordance with its terms, all of which shall survive termination of this Agreement at any time) and there shall be no liability as a result thereof on the part of Purchasers or the Company or their respective directors, officers and Affiliates, except (i) the Company may have liability as provided in Section 8.3, and (ii) nothing shall relieve any party from liability for fraud or any willful breach of this Agreement.

SECTION 8.3 Termination Fee.

(a) In the event that:

(i) within sixteen (16) months after termination of this Agreement pursuant to Section 8.1(b)(ii), 8.1(b)(iii) or 8.1(d) the Company shall have consummated an Alternative Bio Companies Takeover Proposal (as defined below); or

(ii) this Agreement is terminated by the Company pursuant to Section 8.1(c)(i);

then the Company shall (A) in the case of a termination described in paragraph (a)(i) of this Section 8.3, upon the consummation of the transaction contemplated by such Alternative Bio Companies Takeover Proposal, or (B) in the case of a termination described in paragraph (a)(ii) of this Section 8.3, on the date of such termination, pay Purchasers the Termination Fee (as defined below) by wire transfer of immediately available funds to an account designated by Purchasers. Upon failure to timely pay any amount payable under this Section 8.3, interest shall accrue on such unpaid amount at the rate of interest announced publicly by JPMorgan Chase Bank as its “reference rate” (on the basis of a 365-day year). “Alternative Bio Companies Takeover Proposal” means a Bio Companies Takeover Proposal that involves the purchase, in a single transaction or series of related transactions, of (i) more than 50% of the assets of the Bio Companies or more than 50% of the equity securities in the Bio Companies (“Alternative Bio Companies Transaction”) or (ii) all or substantially all of the assets of or the equity securities in the Biopharma Companies (“Alternative Biopharma Transaction”). “Termination Fee” means (x) in the case of a termination described in paragraph (a)(ii) of this Section 8.3, US $18,354,000; (y) in the case of an Alternative Bio Companies Transaction, US $18,354,000 less the amount of any Termination Fee previously paid in respect of an Alternative Biopharma Transaction; or (z) in the case of an Alternative Biopharma Transaction, US $2,000,000 unless Purchasers have previously received a Termination Fee in respect of an Alternative Bio Companies Transaction, in which case no Termination Fee shall be payable in connection with such Alternative Biopharma Transaction.

(b) Purchasers and the Company acknowledge and agree that the payment of the Termination Fee as contemplated by Section 8.3(a) is reasonable and not excessive in light of the nature of the transactions contemplated by this Agreement. Purchasers’ right to receive the Termination Fee pursuant to this Section 8.3 shall not be the exclusive remedy for any breach by the Company of any of the representations, warranties, covenants or other provisions of this Agreement and shall be in addition to any other remedies available at law or in equity to Purchasers.

SECTION 8.4 Acknowledgement. The Company acknowledges and agrees that the agreements contained in Section 8.3 are an integral part of the Bio Companies Transactions and that, without these agreements, Purchasers would not enter into this Agreement. If the Company fails promptly to pay the Termination Fee or and, in order to obtain such payment, Purchasers commence a suit that results in a judgment against the Company for the Termination Fee or any portion thereof, the Company shall pay to Purchasers their reasonable costs and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such suit.

ARTICLE IX

INDEMNIFICATION

SECTION 9.1 Indemnification by the Sellers. Following the Closing, except with respect to Taxes (which shall be governed exclusively by Article VI), employee benefits of or other Liabilities to Transferred Bio Companies Employees and Former Bio Companies Employees (which shall be governed exclusively by Article VII) and as expressly provided in the Transition Services Agreement, the Company and the other Sellers, jointly and severally, shall, to the fullest extent permitted by applicable Law, indemnify, defend and hold harmless Purchasers, the Bio Companies and each of their respective Affiliates, directors, officers, successors and assigns (the “Purchaser Indemnitees”) from and against any and all Losses suffered or incurred by any of the Purchaser Indemnitees arising out of, resulting from or relating to any Company Liability (including, without limitation, arising out of the failure of the Company, the other Sellers or their respective Subsidiaries (other than the Bio Companies) to pay, perform or otherwise discharge when due any such Company Liability), whether arising prior to, on or after the Closing.

SECTION 9.2 Indemnification by Purchasers. Following the Closing, except with respect to Taxes (which shall be governed exclusively by Article VI), employee benefits of or other Liabilities to Transferred Bio Companies Employees and Former Bio Companies Employees (which shall be governed exclusively by Article VII) and as expressly provided in the Transition Services Agreement, Purchasers shall, jointly and severally, to the fullest extent permitted by applicable Law, indemnify, defend and hold harmless the Company, each Affiliate of the Company and each of their respective directors, officers, employees, successors and assigns (the “Company Indemnitees”) from and against any and all Losses suffered or incurred by any of the Company Indemnitees arising out of, resulting from or relating to any Bio Companies Liability (including, without limitation, arising out of the failure of any Purchaser or any of the Bio Companies to pay, perform or otherwise discharge when due any such Bio Companies Liability), whether arising prior to, on or after the Closing.

SECTION 9.3 Limitations on Indemnification Obligations. The amount which any party (an “Indemnifying Party”) is or may be required to pay to any other party (an “Indemnitee”) pursuant to Section 9.1 or Section 9.2 shall be reduced (including, without limitation, retroactively) by any Insurance Proceeds or other amount actually recovered by or on behalf of such Indemnitee, in reduction of the related Loss arising out of a Company Liability or Bio Companies Liability; provided, that no party is required to maintain insurance for such purpose. If an Indemnitee shall have received the payment required by this Agreement from an Indemnifying Party in respect of any Loss arising out of a Company Liability or Bio Companies Liability and shall subsequently actually receive Insurance Proceeds or other amounts in respect of such Loss arising out of a Company Liability or Bio Companies Liability, then such Indemnitee shall pay to such Indemnifying Party a sum equal to the amount of such Insurance Proceeds or other amounts actually received (up to but not in excess of the amount of any indemnity payment made hereunder). An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto, or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being

expressly understood and agreed that no insurer or any other third party shall be entitled to a “windfall” (i.e., a benefit they would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification provisions hereof.

SECTION 9.4 Procedures for Indemnification of Third Party Claims. Procedures for indemnification of Third Party Claims shall be as follows:

(a) If an Indemnitee shall receive notice or otherwise learn of the assertion by a Person (including, without limitation, any Governmental Authority) who is not a party to this Agreement of any claim or of the commencement by any such Person of any Action or Proceeding (a “Third Party Claim”) with respect to which an Indemnifying Party may be obligated to provide indemnification pursuant to Section 9.1 or Section 9.2, such Indemnitee shall give such Indemnifying Party written notice thereof promptly after becoming aware of such Third Party Claim; provided that the failure of any Indemnitee to give notice as provided in this Section 9.4(a) shall not relieve the related Indemnifying Party of its obligations under this Article IX, except to the extent that such Indemnifying Party is prejudiced by such failure to give notice. Such notice shall describe the Third Party Claim in reasonable detail and, if ascertainable, shall indicate the amount (estimated if necessary) of the Loss that has been or may be sustained by such Indemnitee.

(b) An Indemnifying Party may elect to defend or to seek to settle or compromise, at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel, any Third Party Claim. Within thirty (30) days after the receipt of notice from an Indemnitee in accordance with Section 9.4(a) (or sooner, if the nature of such Third Party Claim so requires), the Indemnifying Party shall notify the Indemnitee whether the Indemnifying Party will assume responsibility for defending such Third Party Claim. After notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third Party Claim, such Indemnifying Party shall not be liable to such Indemnitee under this Article IX for any legal or other expenses (except expenses approved in advance by the Indemnifying Party) subsequently incurred by such Indemnitee in connection with the defense thereof; provided that if the defendants in any such claim include both the Indemnifying Party and one or more Indemnitees and in any Indemnitee’s reasonable judgment a conflict of interest between one or more of such Indemnitees and such Indemnifying Party exists in respect of such claim, such Indemnitees shall have the right to employ separate counsel to represent such Indemnitees and in that event the reasonable fees and expenses of such separate counsel (but not more than one separate counsel reasonably satisfactory to the Indemnifying Party) shall be paid by such Indemnifying Party. If an Indemnifying Party elects not to assume responsibility for defending a Third Party Claim, or fails to notify an Indemnitee of its election as provided in this
Section 9.4(b), such Indemnitee may defend or (subject to the remainder of this Section 9.4(b) and Section 9.4(d)) seek to compromise or settle such Third Party Claim at the expense of the Indemnifying Party. Neither an Indemnifying Party nor an Indemnitee shall consent to entry of any judgment or enter into any settlement of any Third Party Claim which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee, in the case of a consent or settlement by an Indemnifying Party, or the Indemnifying Party, in the case of a consent or settlement by the Indemnitee, of a written release from all Liability in respect to such Third Party Claim.

(c) If an Indemnifying Party chooses to defend or to seek to compromise or settle any Third Party Claim, the related Indemnitee shall make available to such Indemnifying Party any personnel or any books, records or other documents within its control or which it otherwise has the ability to make available that are necessary or appropriate for such defense, settlement or compromise, and shall otherwise cooperate in the defense, settlement or compromise of such Third Party Claim.

(d) Notwithstanding anything in this Section 9.4 to the contrary, neither an Indemnifying Party nor an Indemnitee may settle or compromise any claim over the objection of the other; provided, however, that consent to settlement or compromise shall not be unreasonably withheld, conditioned or delayed. If an Indemnifying Party notifies the related Indemnitee in writing of such Indemnifying Party’s desire to settle or compromise a Third Party Claim on the basis set forth in such notice (provided that such settlement or compromise includes as an unconditional term thereof the giving by the claimant or plaintiff of a written release of the Indemnitee from all Liability in respect thereof) and the Indemnitee shall notify the Indemnifying Party in writing that such Indemnitee declines to accept any such settlement or compromise, such Indemnitee may continue to contest such Third Party Claim, free of any participation by such Indemnifying Party, at such Indemnitee’s sole expense. In such event, the obligation of such Indemnifying Party to such Indemnitee with respect to such Third Party Claim shall be equal to (i) the costs and expenses of such Indemnitee prior to the date such Indemnifying Party notifies such Indemnitee of the offer to settle or compromise (to the extent such costs and expenses are otherwise indemnifiable hereunder) plus (ii) the lesser of (x) the amount of any offer of settlement or compromise which such Indemnitee declined to accept and (y) the actual out-of-pocket amount such Indemnitee is obligated to pay subsequent to such date as a result of such Indemnitee’s continuing to pursue such Third Party Claim.

(e) In the event of payment by an Indemnifying Party to any Indemnitee in connection with any Third Party Claim, such Indemnifying Party shall, to the fullest extent permitted by applicable Law, be subrogated to and shall stand in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right or claim relating to such Third Party Claim against any claimant or plaintiff asserting such Third Party Claim or against any other Person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right or claim.

SECTION 9.5 Other Procedures for Indemnification.

(a) Any claim on account of a Loss which does not result from a Third Party Claim shall be asserted by written notice given by the Indemnitee to the related Indemnifying Party. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30) day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment. If such Indemnifying Party does not respond within such thirty (30) day period or rejects such claim in whole or in part, such Indemnitee shall be free to pursue such remedies as may be available to such party under this Agreement or under applicable Law.

(b) In addition to any adjustments required pursuant to Section 9.3, if the amount of any Loss shall, at any time subsequent to the payment required by this Agreement, be reduced by recovery, settlement or otherwise, the amount of such reduction, less any expenses incurred in connection therewith, shall promptly be repaid by the Indemnitee to the Indemnifying Party.

SECTION 9.6 Remedies Cumulative. The remedies provided in this Article IX shall be cumulative and shall not preclude assertion by an Indemnitee of any other rights or the seeking any and all other remedies against any Indemnifying Party.

SECTION 9.7 Survival of Indemnities. The obligations of each of the parties under this Article IX shall survive the sale or other transfer by it of any assets or businesses or the assignment by it of any Liabilities with respect to any Loss of the other related to such assets, businesses or Liabilities.

EXHIBIT A

FORM OF TRANSITION SERVICES AGREEMENT

This TRANSITION SERVICES AGREEMENT (this “Agreement”) is made as of [ ], 2006, by and between CAMBREX CORPORATION, a Delaware corporation (“Cambrex”), LONZA AMERICA INC., a Delaware corporation, LONZA BIOPRODUCTS AG, a Swiss company, and LONZA SALES AG, a Swiss company (collectively, “Purchasers”);

W I T N E S S E T H:

WHEREAS, pursuant to that certain Stock Purchase Agreement, dated as of October 23, 2006 (the “Stock Purchase Agreement”; capitalized terms used herein and not otherwise defined herein have the meanings given to such terms in the Stock Purchase Agreement), by and among Cambrex and Purchasers, Cambrex has agreed to sell and Purchasers have agreed to purchase (i) all of the issued and outstanding capital stock of the Bio Companies (excluding the shares of CBM Intellectual Property Inc., a Nevada corporation (“CBM Intellectual Property”)) and (ii) all of the assets of CBM Intellectual Property; and

WHEREAS, pursuant to the Stock Purchase Agreement, Cambrex has agreed to provide certain transition services to Purchasers and the Bio Companies following the Closing Date on the terms and subject to the conditions set forth in this Agreement;

NOW, THEREFORE, in consideration of the premises and covenants set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Cambrex and Purchasers agree as follows:

1. Transition Services. During the term of this Agreement as set forth in Section 5 below (the “Term”), Cambrex shall assist and cooperate with Purchasers to create an orderly transition of the Bio Companies Business in the areas described in Annex A by providing, or causing its Affiliates to provide, to Purchasers and their respective Affiliates (but only to the extent such Affiliates operate the Bio Companies Business) the services set forth in Annex A attached hereto (the “Transition Services”), from the date of this Agreement and for the period of time described in Annex A attached hereto with respect to each of the Transition Services, in the manner and at a relative level of service consistent in all material respects with, but in no event materially higher or lower than, the typical level of service provided by Cambrex or its Affiliates to the Bio Companies Business immediately prior to the date hereof; provided that in no event are such Transition Services deemed to be expert services. Cambrex shall not be obligated to provide any services to Purchasers other than the Transition Services; provided that (i) if any service that Cambrex provided to any of the Bio Companies in the ordinary course of business immediately prior to the date hereof and that is of a transitional nature is inadvertently omitted from the list of Transition Services or (ii) if any Purchaser requires additional services of a transitional nature, then Cambrex and Purchaser agree to negotiate in good faith to amend this Agreement to include such services (to the extent, and only to the extent, that such services can be provided without resulting in a conflict of interest for Cambrex) in Annex A at a cost to be determined in good faith, using the same methodology as Cambrex used to determine the costs set forth in Annex A. Nothing in this Agreement shall require Cambrex to provide priority to

Purchasers with respect to the Transition Services over Cambrex’s businesses or those of any of its Affiliates, Subsidiaries or divisions

2. Billing and Payment. Cambrex shall issue Purchasers invoices for the Transition Services at the beginning of each month during the Term. Each Purchaser shall promptly pay any bills and invoices that it receives from Cambrex or its Affiliates for the Transition Services. Each Purchaser shall pay interest on any amount overdue under this Agreement at the Prime Rate as published in the Wall Street Journal, Eastern Edition in effect from time to time during the term of this Agreement plus two percent (2%) from the date due until payment, or, if lower, the highest interest rate permitted by Law. All invoices shall be paid by wire transfer in accordance with the instructions provided by Cambrex (in writing to the applicable Purchaser or Purchasers) not later than ten (10) days following receipt by the applicable Purchaser or Purchasers of Cambrex’s invoice, unless such invoice is disputed in good faith within ten (10) days after receipt of such invoice. In the event that any Purchaser fails to make payment to Cambrex within forty-five (45) days following receipt by such Purchaser of Cambrex’s invoice (other than any invoice that was timely disputed in good faith), Cambrex may terminate this Agreement upon notice to Purchasers. Purchasers shall not offset any amounts owing to it by Cambrex or any of Cambrex’s Affiliates against amounts payable by Purchaser hereunder.

3. General Intent. Cambrex shall use its reasonable commercial efforts to provide the Transition Services at the price set forth in
Annex A during the Term and such other transition assistance as the parties may otherwise agree. Each Purchaser agrees to use its reasonable commercial efforts to end its need to use such assistance as soon as reasonably practicable and in all events to end such need with respect to each Transition Service not later than the termination of this Agreement pursuant to Section 5.

4. Walkersville Facility. In connection with the provision of the Transition Services, during the Term and for thirty (30) days thereafter, Cambrex and its Representatives shall have full physical access to the data center facilities at Walkersville; provided that Cambrex and its employees and Representatives shall comply with all of the security policies and procedures of Purchasers and the Bio Companies. In addition, all Cambrex employees with offices in the Walkersville facility immediately prior to the date hereof who are providing Transition Services to Purchasers shall be permitted to retain their offices in the Walkersville facility during the Term.

5. Term of Agreement. The term of this Agreement shall commence on the date hereof and shall continue (unless sooner terminated pursuant to the terms hereof) for a period not to exceed two (2) months (the “Transition Period”). Purchasers may request an extension of the term of any Transition Service set forth in Annex A by submitting a written request to Cambrex to extend the term of such service (the “Extension Period”) thirty (30) days prior to the end of any such service term. Cambrex may continue to provide such Transition Service to Purchasers at the price set forth in Annex A during any Extension Period, and Cambrex’s consent to continue providing such service shall not be unreasonably withheld. Notwithstanding anything herein to the contrary, this Agreement and the obligations of Cambrex to provide any services hereunder shall automatically terminate one (1) year after the date hereof.

6. Partial Termination. Any and all of the Transition Services provided by Cambrex and its Affiliates are only terminable earlier than the period specified in Annex A attached hereto by Purchasers on thirty (30) days’ prior written notice to Cambrex. As soon as reasonably practicable following receipt of any such notice, Cambrex shall advise Purchasers as to whether termination of such Transition Service will require the termination or partial termination of, or otherwise affect the provision of, certain other Transition Services. If such is the case, Purchasers may withdraw their termination notice. Otherwise, such termination shall be final. All periodic fees or charges under this Agreement are to be computed on a calendar month basis and, in the event that any Transition Services are terminated pursuant to this Section, the fees or charges shall be prorated on a per diem basis for any partial month. Notwithstanding the foregoing, during any Extension Period the fees and charges shall not be prorated for any partial period for any reason.

7. Non-Solicitation of Employee. For a period of two (2) years following the date hereof, neither Purchasers nor any of their respective Affiliates will directly or indirect solicit the employment of any officer or employee of Cambrex or any of its Affiliates so long as they are employed by Cambrex or any of its Affiliates, without obtaining the prior written consent of Cambrex, provided that the foregoing shall not prohibit any general solicitation or advertising activities not targeted to any such officer or employee nor apply to any individual whose employment is terminated by Cambrex or any Affiliate of Cambrex.

8. Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by any of the parties without the prior written consent of the other party; provided that such consent shall not be required (i) for assignments and transfers by operation of Law, (ii) in the event Cambrex assigns any or all of its rights, interests and obligations hereunder to a Person with whom Cambrex merges or to whom Cambrex sells all or substantially all of its assets and (iii) for assignments and transfers by either party to one or more of its Subsidiaries or Affiliates (in the case of Purchasers such Subsidiaries or Affiliates must be Subsidiaries or Affiliates that operate the Bio Companies Business). Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns. Any purported assignment not permitted under this Section shall be null and void.

9. Confidentiality. Each of the parties will hold, and will cause its Affiliates and Representatives to hold, in strict confidence from any Person (other than any such Affiliate or Representative), unless compelled to disclose by judicial or administrative process or by other requirements of any Law, all confidential or competitively sensitive information received in connection with the provision of the Transition Services, except to the extent that such information can be shown to have been (i) in the public domain (either prior to or after the furnishing of such information) through no fault of such party or its Affiliates or its Representatives or (ii) later acquired by such party, its Affiliates or its Representatives from another source if such party, its Affiliates or its Representatives is unaware that such source is under an obligation to the other party to keep such information confidential. This duty shall continue throughout the term of this Agreement, and any renewals or extensions thereof, and after termination thereof for a period of three (3) years.

10. Limitation of Liability. Neither party shall be liable to the other party or any third party for any special, punitive, consequential, incidental or exemplary damages (including lost or anticipated revenues or profits relating to the same) arising from any claim relating to this Agreement or any of the services provided hereunder, whether such claim is based on warranty, contract, tort (including negligence or strict liability) or otherwise, even if an authorized representative of such party is advised of the possibility or likelihood of the same. In addition, neither party shall be liable to the other party or any third party for any direct damages from any claim arising or allegedly arising from providing or failing to provide the Transition Services or any other services, except to the extent, but only to the extent, that any such claims arise from gross negligence, reckless or willful misconduct or fraud.

11. Notices. All notices, reports, and receipts shall be in writing and shall be deemed duly given on (i) the date of personal or courier delivery, (ii) the date of transmission by facsimile or other electronic transmission service, provided a confirmation copy is also sent no later than the next business day by postage paid, return receipt requested first-class mail or (iii) three (3) business days after the date of deposit in the United States mails, by postage paid, return receipt requested first-class mail, addressed as follows:

The failure or delay of either party to insist upon the other party’s strict performance of the provisions in this Agreement or to exercise in any respect any right, power, privilege, or remedy provided for under this Agreement shall not operate as a waiver or relinquishment thereof, nor shall any single or partial exercise of any right, power, privilege, or remedy preclude other or further exercise thereof, or the exercise of any other right, power, privilege, or remedy; provided, however, that the obligations and duties of either party with respect to the performance of any term or condition in this Agreement shall continue in full force and effect.

13. Relationship of Parties. Except as specifically provided herein, neither party shall act or represent or hold itself out as having authority to act as an agent or partner of the other party, or in any way bind or commit the other party to any obligations. Nothing contained in this Agreement shall be construed as creating a partnership, joint venture, agency, trust or other association of any kind, each party being individually responsible only for its obligations as set forth in this Agreement. All activities by Cambrex under the terms of this Agreement shall be carried on by Cambrex as an independent contractor and not as an agent for Purchasers. Employees of Cambrex performing services hereunder shall remain Cambrex’s employees and shall not be deemed to be employees of any Purchaser.

14. Force Majeure. If either party is prevented from complying, either totally or in part, with any of the terms or provisions of this Agreement by reason of fire, flood, storm, strike, lockout or other labor trouble, any Law, demand or other requirement of any Governmental Authority, riot, war, rebellion, acts of terrorism, acts of the public enemy or other causes beyond the reasonable control of such party or other acts of God, then upon written notice to the other party, the affected provisions and/or other requirements of this Agreement shall be suspended during the period of such disability (the “Disability Period”) and the affected party shall have no liability to the other party or any other party in connection therewith; provided that this Section 14 shall not apply to any payment to Cambrex required by this Agreement to the extent Cambrex or its Affiliates have provided the services for which payment is sought in accordance with the terms of this Agreement. The affected party shall make all reasonable

efforts to remove such disability within thirty (30) days after giving notice of such disability (provided that such efforts shall not include settling any labor disputes). At the request of Purchasers, the Term shall be extended for a time period equal to any Disability Period.

15. Interpretation. The headings and captions contained in this Agreement and in Annex A attached hereto are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. The use of the word “including” herein shall mean “including without limitation”.

16. Counterparts. This Agreement may be executed in one or more counterparts (including by means of signature pages via facsimile), all of which shall be considered one and the same agreement, and shall become effective when one or more such counterparts have been signed by each of the parties and delivered to the other party.

17. Entire Agreement. This Agreement and the Stock Purchase Agreement contain the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, whether written or oral, relating to such subject matter.

18. Representation by Counsel; Interpretation. Cambrex and Purchasers acknowledge that each of them has been represented by counsel in connection with this Agreement and the transactions contemplated hereby. Accordingly, any rule of Law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the party that drafted it has no application and is expressly waived.

19. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be valid and effective under applicable Law, but if any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof.

20. Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware applicable to a contract executed and performed in such State, without regard to principles of conflict of Laws that would require the application of the Laws of another jurisdiction.

21. Survival. The provisions of Sections 2, 4, 7-13 and 15-22 shall survive any termination of this Agreement.

22. Annex A. Annex A attached hereto and referred to herein is hereby incorporated in and made a part of this Agreement as if set forth in full herein.
