ARTICLE III

PURCHASE PRICE

     3.1 Determination of Purchase Price.

          (a) Subject to the terms and conditions of this Agreement and in consideration of the sale, transfer, assignment, conveyance and delivery by Seller and Aerojet (to the extent of their respective ownership interests) of the Purchased Assets to Purchaser, Purchaser shall pay to Seller an aggregate amount equal to One Hundred Nineteen Million Dollars ($119,000,000), which shall be paid at Closing as set forth in Section 3.1(b) and which shall be subject to adjustment pursuant to the terms of this Section 3.1 (as so adjusted, the “Purchase Price”).

          (b) The Purchase Price shall be paid by Purchaser to Seller at the Closing as follows:

     (i) by wire transfer of immediately available funds in an aggregate amount of One Hundred Million Dollars ($100,000,000); and

     (ii) by delivery of a promissory note payable to Seller in the original principal amount of Nineteen Million Dollars ($19,000,000) on substantially the terms and conditions set forth on Exhibit D (the “Note”).

          (c) No later than three (3) Business Days prior to the Closing Date, Seller shall prepare and deliver, or cause to be prepared and delivered, to Purchaser a written estimate (the “Estimated Statement”) of the items of the 2005 Budgeted Capital Expenditures that have been both incurred and paid by or on behalf of Seller as of the Closing Date (“Completed Capital Expenditures”). Subject to further adjustment pursuant to Section 3.1(f) hereof, (A) to the extent that the Estimated Statement reflects Completed Capital Expenditures of less than Nineteen Million Dollars ($19,000,000), the cash portion of the purchase price payable at Closing shall be decreased by the amount of such difference; and (B) to the extent that the Estimated Statement reflects Completed Capital Expenditures of more than Nineteen Million Dollars ($19,000,000), the cash portion of the purchase price payable at Closing shall be increased by the amount of such excess.

          (d) Within 45 calendar days after the Closing Date, Purchaser shall cause to be prepared and delivered to Seller (i) a balance sheet of the Business as of the

15

Exhibit 2.1

Closing Date prepared in accordance with GAAP applied on a consistent basis with the May Balance Sheet and including such items set forth on the May Balance Sheet (the “Closing Balance Sheet”), and (ii) a statement (“Capital Expenditures Statement”) of the Completed Capital Expenditures.

          (e) Following receipt of the Closing Balance Sheet and the Capital Expenditures Statement, Seller will have 45 calendar days to review both the Closing Balance Sheet and the Capital Expenditures Statement, after which period, if Seller has not disputed in writing (an “Objection”) the Closing Balance Sheet or the Capital Expenditures Statement, Seller will be deemed to have accepted and agreed with the Closing Balance Sheet and the Capital Expenditures Statement, and the Closing Balance Sheet and the Capital Expenditures Statement shall be final and binding upon the Parties. During such period, Purchaser shall make available its accounting staff and internal auditors to respond to questions of Seller relating to the Closing Balance Sheet and the Capital Expenditures Statement and shall furnish to Seller such work papers and other documents and information relating to the Closing Balance Sheet and the Capital Expenditures Statement as Seller may reasonably request and are available to Purchaser or its Affiliates. An Objection shall set forth a general description of the basis of the Objection and the adjustments to the Closing Balance Sheet or the Capital Expenditures Statement or both that Seller believes should be made, which Objection must be delivered to Purchaser on or before the last day of such 45-day period, in which case each item in the Closing Balance Sheet and the Capital Expenditures Statement that is not disputed in such Objection shall be deemed to be agreed to by Seller and shall be final and binding upon the Parties. Purchaser shall have 30 days to review and respond to the Objection.

          (f) To the extent that the Estimated Statement reflects Completed Capital Expenditures of more than the amount shown on the Capital Expenditures Statement (such difference an “Overpayment”), then the purchase price shall be decreased by the amount of such Overpayment, and Seller shall promptly make payment in immediately available funds to Purchaser in the amount of the Overpayment. To the extent that the Estimated Statement reflects Completed Capital Expenditures of less than the amount shown on the Capital Expenditures Statement (such difference an “Underpayment”), the purchase price shall be increased by the amount of such Underpayment, and Purchaser shall promptly make payment in immediately available funds to Seller in the amount of such Underpayment.

          (g) The Parties shall attempt in good faith to reach an agreement with respect to any matters in dispute regarding the Closing Balance Sheet and/or the Capital Expenditures Statement. If the Parties are unable to reach agreement with respect to the Closing Balance Sheet and/or the Capital Expenditures Statement within 30 days following the delivery of Purchaser’s response to an Objection, any remaining disputed items shall be referred for final binding resolution to an accounting firm mutually acceptable to both Parties or, in the absence of such agreement, by an accounting firm (with no existing or prior material business with either Seller or Purchaser) of national reputation selected by lot. The selected accounting firm shall be directed by the Parties to (i) determine each disputed item on the Closing Balance Sheet on the basis consistent with the May Balance Sheet, (ii) determine each disputed item on the Capital

16

Exhibit 2.1

Expenditures Statement in accordance with GAAP, (iii) render its determination within 30 days after such referral for binding resolution is made, and (iv) upon reaching a determination, deliver to both Purchaser and Seller a modified Closing Balance Sheet and/or Capital Expenditures Statement reflecting the items that have become final and binding upon the Parties and the accounting firm’s determination of each disputed item. The determination by the accounting firm so selected of the Closing Balance Sheet and/or the Capital Expenditures Statement (with such modifications therein, if any, as reflect such determination) shall be conclusive and binding upon the Parties. The fees and expenses of such accounting firm shall be shared equally by the Seller Parties, on the one hand, and Purchaser, on the other hand. Nothing herein shall be construed to authorize or permit the accounting firm to determine any questions or matters whatsoever under or in connection with this Agreement except for the resolution of the disputed items submitted to them for determination in accordance with this Section 3.1(g).

          (h) Each Party shall provide the other Parties and their respective representatives reasonable access to the premises of the Business, to their respective books and records and to their respective appropriate personnel for purposes of preparing and confirming the Closing Balance Sheet, the Capital Expenditures Statement and the CAPEX Statement.

     3.2 Certain Budgeted Capital Expenditures.

          (a) Within 45 days of following the completion of the Identified Capital Project, Purchaser shall cause to be prepared and delivered to Seller a detailed summary (including supporting backup) (the “CAPEX Statement”) of the actual capital expenditures (the “Actual Expenditures”) incurred by the Business for the capital project identified on Schedule 3.2 (the “Identified Capital Project”). In the event that the amount of the Actual Expenditures for the Identified Capital Project exceeds the Guaranteed Amount by Two Million Dollars ($2,000,000.00) or less, then Seller shall promptly make payment in immediately available funds to Purchaser in the amount of fifty percent (50%) of such excess. In the event that the amount of the Actual Expenditures for the Identified Capital Project exceeds the Guaranteed Amount by more than Two Million Dollars ($2,000,000.00), then Seller shall have no obligation to pay Purchaser any amounts (other than the payment obligation set forth in the foregoing sentence). In the event that the amount of the Actual Expenditures for the Identified Capital Project is less than the Guaranteed Amount by Two Million Dollars ($2,000,000.00) or less, then Purchaser shall promptly make payment in immediately available funds to Seller in the amount of fifty percent (50%) of such difference. In the event that the amount of the Actual Expenditures for the Identified Capital Project is less than the Guaranteed Amount by more than Two Million Dollars ($2,000,000.00), then Purchaser shall have no obligation to pay Seller any amounts (other than the payment obligation set forth in the foregoing sentence).

          (b) The Parties shall attempt in good faith to reach an agreement with respect to any matters in dispute regarding the Actual Expenditures and/or the CAPEX Statement. Any disputes regarding the Actual Expenditures or the CAPEX Statement

17

Exhibit 2.1

shall be governed by the same procedures set forth in Section 3.1(g) hereof for the Closing Balance Sheet and the Capital Expenditures Statement.

     3.3 Allocation of Purchase Price.

          The Parties agree that they will use their respective best efforts to determine the allocation of the Purchase Price to meet the requirements of Section 1060 of the Code. Each of the Parties agrees to prepare and file in a timely manner an IRS Form 8594 and other appropriate information, as required by Section 1060 of the Code and pertinent regulations and Internal Revenue Service instructions, with respect to those Purchased Assets required to be reflected on such Form. The Parties each agree to submit to the other a draft copy of any Form 8594 it proposes to file with respect to the Purchased Assets at least 45 days before the proposed filing date thereof and to jointly discuss and attempt to agree, in good faith, to the contents thereof. Each Party shall provide to the other Party the final version of such Form and information promptly after filing. To the extent the amount paid for the Purchased Assets is adjusted after the Closing Date, the Parties agree to revise and amend any agreed Schedule and their respective Forms 8594 in the same manner and according to the same procedure.

Exhibit 2.1

     3.5 Further Conveyances and Assumptions; Consents.

          (a) Without derogating the rights of Purchaser pursuant to Section 7.10, nothing in this Agreement nor the consummation of the Transaction shall be construed as an attempt, offer or agreement to assign any Purchased Asset, including any Contract, Governmental Permit, Environmental Permit, certificate, approval, authorization or other right, which by its terms or by Law is nonassignable without the consent of a Third Party or Governmental Authority or is cancelable by a Third Party or Governmental Authority in the event of an assignment (“Nonassignable Assets”) unless and until such consent shall have been obtained. Seller shall, and shall cause its Affiliates to, use its reasonable best efforts to cooperate with Purchaser at its request in endeavoring to obtain such consents or novations (if appropriate) promptly; provided, however, that such cooperation shall not require Seller or any of its Affiliates to remain secondarily liable or to make any material payment to obtain any such consent or novation with respect to any Nonassignable Asset except as required under applicable statute or regulation with respect to any Governmental Permits and Environmental Permits. To the extent permitted by any applicable Law, Seller and Purchaser shall request that each Governmental Authority or Person whose consent is requested treat as confidential all information, documents and other materials submitted to it in connection with such request.

          (b) Purchaser and Seller shall use their respective reasonable best efforts to obtain, or to cause to be obtained, any consent, substitution, approval or amendment required to novate all obligations under any and all Contracts or other obligations or liabilities that constitute Assumed Liabilities or to obtain in writing the release of Seller and its Affiliates so that, in any such case, Purchaser shall be solely responsible for such Assumed Liabilities.

          (c) Notwithstanding anything in this Agreement to the contrary, unless and until any consent or approval with respect to any Nonassignable Asset is obtained, such Nonassignable Asset shall not constitute a Purchased Asset and any associated liability shall not constitute an Assumed Liability for any purpose under this Agreement.

          (d) In the event that any Governmental Permit, Environmental Permit or right granted by a Governmental Authority that would otherwise have been a Purchased Asset is a Nonassignable Asset, Seller shall provide such assistance as Purchaser may reasonably request in Purchaser’s efforts to obtain a comparable permit, license or right.

          (e) Upon the written request of Purchaser and upon Purchaser’s waiver of the appropriate closing condition, if any such consent shall not be obtained, then Seller and Purchaser shall do all things reasonably necessary and cooperate with each other in any legal, reasonable and economically feasible arrangement designed to provide to Purchaser the benefit of any such Nonassignable Asset (in which case, Purchaser shall make up to and no more than those payments Purchaser would have otherwise been required to make (if any) to obtain the full benefits under such Nonassignable Assets had they been assigned to Purchaser).

Seller shall use commercially reasonable efforts to cooperate in facilitating the performance of Purchaser’s obligation to make such offers. Employment by Purchaser of any such Business Employees accepting such offers (“Transferred Employees”) shall be effective at Closing.

36

Exhibit 2.1

solely responsible for any and all obligations or liability with respect to the employment, or termination of employment, of any such employee.

Nothing in this Agreement shall restrict any right of Purchaser to terminate any employee or to amend or terminate employee benefits after the Closing Date to the extent permitted under applicable laws, rules, regulations and collective bargaining agreements. Purchaser shall grant or cause to be granted full credit to the Transferred Employees for (i) time recognized under the employee benefit plans and employee policies of Seller and its Affiliates and predecessors prior to the Closing Date for purposes of vacation, other paid time off, severance pay, welfare benefits, vesting and eligibility for early retirement under Purchaser’s retirement plans and any other purposes for which the employee’s service may be relevant, and (ii) payments made by Transferred Employees toward welfare plan annual deductible limits and the like. Purchaser shall waive any provisions of its welfare benefit plans pursuant to which any Transferred Employees and their dependents are subject to waiting periods for coverage, provided that such provisions did not previously exist under welfare benefit plans of Seller or its Affiliates with respect to such employees or their dependents immediately prior to the Closing Date.

On or before the Closing Date, Seller shall supplement Schedule 6.2(b) to include any additional Business Employees who experience an “employment loss” between the date of execution of this Agreement and the Closing Date. If, during a 90-day period following the Closing Date, Purchaser takes or omits to take any action that would trigger the WARN Act, Purchaser shall indemnify and hold harmless Seller, from

37

Exhibit 2.1

and against any and all claims which Seller may incur with respect to current and former Business Employees.

          (c) Notwithstanding anything contained in this Agreement to the contrary, Purchaser shall not provide retiree medical benefits under any Employee Benefit Plan to Transferred Employees.

          (d) Purchaser shall implement a severance plan or plans (“Purchaser’s Severance Plan”) that shall provide benefits to any Transferred Employee whose employment is involuntarily terminated without cause after the Closing Date, equal to the benefits such Transferred Employee would have received under Seller’s severance plan that applied to such Transferred Employee immediately prior to the Closing Date. Purchaser’s Severance Plans shall remain in force for at least 12 months following the Closing Date. Purchaser shall indemnify Seller and hold it harmless from and against any and all claims from plans or arrangements that are specifically identified on Schedule 6.2(d) attached hereto and made for severance pay or allowance, termination pay or allowance or pay in lieu of notice (including government-mandated separation benefits) arising out of any action by Purchaser with respect to the employment of any Transferred Employee after the Closing Date.

          (e) Purchaser shall (i) cover the Transferred Employees under a medical and dependent care flexible spending account plan sponsored by Purchaser (“Purchaser’s Section 125 Plan”), (ii) recognize the elections that each such Transferred Employee had in effect under Seller’s medical and dependent care flexible spending accounting plan (“Seller’s Section 125 Plan”) for the calendar year in which such Transferred Employee becomes covered under Purchaser’s Section 125 Plan, (iii) cause Purchaser’s Section 125 Plan to assume the account balances associated with each Transferred Employee’s flexible spending accounts under Seller’s Section 125 Plan, and (iv) be responsible for reimbursement of all previously unreimbursed reimbursable medical and dependent care claims incurred by Transferred Employees in such calendar year. Accordingly, (A) cash equal to any amounts credited to a Transferred Employee’s flexible spending account that has not previously been used to pay a claim of such Transferred Employee shall be transferred by Seller to Purchaser at the Closing Date, and (B) cash equal to any amount of claims paid to a Transferred Employee in excess of the amount credited to such Transferred Employee’s flexible spending account shall be transferred by Purchaser to Seller at the Closing Date.

          (f) Effective as of the Closing Date, Purchaser shall assume and succeed to all of the obligations of Seller under the IAM Agreement, except as otherwise provided herein. In order to satisfy Purchaser’s obligation to provide Group Insurance for Retirees under Article XXXIV of the IAM Agreement, Seller and Aerojet shall permit Transferred Employees hired by Seller or Aerojet prior to January 1, 1997 to participate in Aerojet’s Salaried Retiree Group Medical, Drug and Dental Plans (under the same terms and conditions applicable to salaried retirees of Aerojet and subject to all changes in such terms and conditions uniformly made by Aerojet) upon satisfying the eligibility requirements of such plans. Seller and Aerojet shall count Transferred Employees’

38

Exhibit 2.1

service with, and attainment of age 55 while employed by, Purchaser for purposes of satisfying those eligibility requirements.

          (g) With respect to all Employee Benefits Plans other than an Employee Benefit Pension Plan, except to the extent accrued as a liability on the Closing Balance Sheet, Seller and Seller’s Employee Benefit Plans shall be responsible for all claims incurred prior to the Closing Date. Likewise, Purchaser and Purchaser’s Employee Benefit Plans shall be responsible for all claims incurred on or after the Closing Date. For purposes of this subsection, “incurred” shall mean the provision of any services (i.e., the service date) under Seller’s Employee Benefit Plans, except that with respect to disability benefits, “incurred” shall mean the submission of any claim by a participant or beneficiary for benefits under such plan. Seller shall indemnify Purchaser for any claim incurred prior to the Closing Date pursuant to this subsection, and Purchaser shall indemnify Seller for any claim incurred on or after the Closing Date.

          (h) (i) Effective as of the Closing, Purchaser shall establish and/or amend a tax-qualified, defined contribution plan(s) (each a “Purchaser 401(k) Plan”), to provide for participation by Transferred Employees immediately following the Closing Date. Purchaser may establish or amend one Purchaser 401(k) Plan for salaried Transferred Employees and may establish or amend another Purchaser 401(k) Plan for Transferred Employees covered by the IAM Agreement. A Purchaser 401(k) Plan shall take into account for purposes of eligibility and vesting each Transferred Employee’s service with Seller. The Purchaser 401(k) Plan for Transferred Employees covered by the IAM Agreement shall satisfy the requirements of Article XXXI of the IAM Agreement.

          (ii) Upon Closing, Seller shall fully vest all Transferred Employees’ account balances under the Seller’s defined contribution plan (“Seller’s 401(k) Plan”).

          (iii) All Transferred Employees shall be entitled to elect (A) to receive a distribution of their vested account balances under Seller’s 401(k) Plan in accordance with its terms, (B) to maintain such accounts in Seller’s 401(k) Plan in accordance with its terms, or (C) to elect a rollover of cash equal to their respective account balances (plus any unpaid participant loans in such accounts) directly to a Purchaser 401(k) Plan designated by the Purchaser. If any Transferred Employee elects to roll over his or her account balance to Purchaser 401(k) Plan, then Seller shall cause the trustee of Seller’s 401(k) Plan to transfer to the trustee or other funding agent of such Purchaser 401(k) Plan cash equal to the assets allocated to the accounts of such employee under Seller’s 401(k) Plan, plus any note or other evidence of any outstanding participant loan from Seller’s 401(k) Plan. Seller shall indemnify Purchaser, and Purchaser’s officers, employees and agents against any liability for fiduciary breach incurred as a result of the liquidation of a Transferred Employee’s account balance under Seller’s 401(k) Plan to cash prior to the rollover of such Transferred Employee’s account balance to a Purchaser 401(k) Plan. No rollover shall be made unless and until Seller and Purchaser each provide each other with a current favorable determination letter from the IRS, or an opinion of counsel, as to the qualification (as to form rather than operation) of its respective plan(s).

39

Exhibit 2.1

          (iv) Except as provided in the indemnification provision of Paragraph (iii) above, upon completion of the rollover of assets described in this Section 6.2(h) to a Purchaser 401(k) Plan, such Purchaser 401(k) Plan shall assume the benefit liabilities under Seller’s 401(k) Plan with respect to the amount of cash and participant loans rolled over with respect to those Transferred Employees who have elected a rollover to such Purchaser 401(k) Plan, and neither Seller nor Seller’s 401(k) Plan shall have any further obligation or responsibility with respect to such liabilities, which shall be considered for all purposes as having been satisfied as a result of such rollover.

     (i) (i) Effective as of the Closing, Purchaser shall establish or amend a tax-qualified, defined benefit pension plan(s) (each a “Purchaser Pension Plan”) to provide for participation by the Transferred Employees immediately following the Closing Date. A Purchaser Pension Plan shall take into account all relevant aspects of a Transferred Employee’s service with Seller and its Affiliates before the Closing Date. The Purchaser Pension Plan for Transferred Employees covered by the IAM Agreement shall satisfy the requirements of Article XXXI of the IAM Agreement.

     (ii) As soon as practicable following the Closing Date, but no later than sixty (60) days following the Closing Date, Seller and/or Parent shall cause to be transferred from the GenCorp Consolidated Pension Plan (“Seller’s Pension Plan”) to a Purchaser Pension Plan designated by Purchaser cash equal to the accrued benefit obligation under Seller’s Pension Plan as of the Closing Date for all Transferred Employees (the “Accrued Benefit Obligation”), adjusted to reflect a pro rata share of the investment experience (positive or negative) of Seller’s Pension Plan from the Closing Date until the date of transfer, and decreased by any benefit payments made with respect to Transferred Employees and a pro rata share of normal administrative and investment expenses incurred between the Closing Date and the date of transfer.

          (A) The Accrued Benefit Obligation shall be determined using actuarial assumptions and methods considered by Seller’s actuary to be reasonable under Code section 414(l) as of the Closing Date. Within a reasonable time prior to the transfer of the Accrued Benefit Obligation in accordance with this Section 6.2(i)(ii), Seller shall provide to Purchaser the data upon which Seller’s actuary determined the Accrued Benefit Obligation, including the names, service dates, credited service, accrued benefits at the Closing Date, compensation history and other relevant information with respect to each Transferred Employee’s accrued benefit.

          (B) If Purchaser’s actuary identifies, within thirty (30) days of the foregoing transfer of assets, a disagreement between that actuaries that is not mutually resolved concerning the amount of the Accrued Benefit Obligation that is more than five percent (5%) of the Accrued Benefit Obligation as determined by Seller’s actuary, each of such actuaries shall together, appoint a third actuary from a nationally recognized actuarial firm to resolve their differences (the costs of the third actuary shall be shared equally by Seller and Purchaser). In such event, the third actuary’s determination of any dispute shall be final.

          (C) Notwithstanding anything contained in this Section 6.2(i)(ii), no transfer of assets shall be made unless and until Seller and Purchaser provide each other with a copy of a

40

Exhibit 2.1

current favorable determination letter from the IRS as to the qualification of its respective plan or, if such plan has not yet received a determination letter from the IRS or has been amended since the date of said determination, an opinion of legal counsel to the plan indicating that there are no plan provisions that in form are reasonably likely to adversely affect the qualified status of the plan.

     (iii) As of the date of transfer of assets in accordance with Section 6.2(i)(ii), Purchaser’s Pension Plan shall assume the liability and obligation for payment of benefits accrued by the Transferred Employees under Seller’s Pension Plan, consistent with the calculation of the Accrued Benefit Obligation of Transferred Employees under Section 6.2(i)(ii) hereof.

     (iv) Seller represents that the value of assets to be transferred to Purchaser’s Pension Plan(s) shall meet the requirements of Treasury Regulation Section 1.414(l)-1, as certified by Seller’s actuary.

     (v) Immediately after the transfer of assets and liabilities contemplated by this Section 6.2(i), Purchaser’s Pension Plan(s) shall provide a benefit for each Transferred Employee that is at least equal to the accrued benefit of such Transferred Employee under Seller’s Pension Plan at the Closing Date, which shall be consistent with the calculation of the Accrued Benefit Obligation of Transferred Employees under Section 6.2(i)(ii) hereof. A Transferred Employee’s service with Purchaser shall be counted for the purpose of vesting and early retirement subsidies applicable to such transferred accrued benefit.

          (j) For a period of twelve (12) months following the date of this Agreement, Purchaser shall not make any material changes to any of the Purchaser’s Employee Benefit Plans, to the extent that the effect of any such change would be to make the benefits provided under such modified plans, together with any new or existing plans that Purchaser may permit Transferred Employees to participate in during such twelve-month period, not comparable, on an aggregate basis, to those benefits under Purchaser’s Employee Benefit Plans to which Transferred Employees would be entitled to receive under Section 6.2(a) of this Agreement if the Closing were to occur as of the date hereof.

Each Party has advised the other that it believes it must issue a press release regarding the Transaction and intends to do so. Each Party agrees that it will promptly review any and all such press releases from the other Party and will not unreasonably delay its consent nor unreasonably withhold its consent.

In case at any time after the Closing Date any further action is necessary or desirable to carry out the purposes of this Agreement, each of the Parties hereto shall take all such action, including without limitation, to vest, secure, perfect, protect or enforce the rights and interests of Purchaser in and to the Pharmaceutical Intellectual Property that does not constitute Licensed Intellectual Property (the “Transferred Property Rights”). Seller Parties shall be responsible for one-half and Purchaser shall be responsible for one-half of all filing fees related to formal filings required for the assignment and transfer of the Transferred Property Rights.

Purchaser shall use its reasonable best efforts to provide to Seller or Other Seller any Tax Returns which it is required to prepare and file at least ten days before such Tax Returns are due to be filed.

     7.9 Tax Matters.

          (a) Except as provided in Section 7.8, Seller shall be responsible for filing all returns for Taxes relating to the Purchased Assets and the income and operation of Seller before the Closing, regardless of when such returns are due.

          (b) The Parties understand and agree that this Agreement shall be interpreted, and that the Parties shall administer their dealings in relation to this Agreement, so as to effect the following principles relating to Taxes:

          (i) Purchaser shall be responsible for (A) all Taxes arising out of the ownership and operation of the Business attributable to the period beginning on the day after the Closing Date, (B) the Assumed Taxes, and (C) one-half of any Transfer Taxes as provided in Section 7.8.

47

Exhibit 2.1

          (iv) The Party responsible for any Tax pursuant to Sections 7.9(b)(i) or (ii) shall be responsible for any increase in such Tax upon audit, provided, however, that Purchaser shall not be liable for an increase in Tax upon audit for any Tax included in Assumed Taxes in excess of the amount of such Tax that was accrued on the Closing Balance Sheet.

     7.10 Licensed Intellectual Property.

          Subject to Section 8.5, this Section 7.10 and the rights of any Third Party, and except for (a) the Polyfox Intellectual Property and (b) those Intellectual Property Rights (i) considered Excluded Assets, or (ii) governed by the Trademark License Agreement, effective as of the Closing Date, Aerojet grants to Purchaser an irrevocable, perpetual, exclusive, sublicensable, transferable, worldwide and royalty-free right and license under the Pharmaceutical Intellectual Property that is not owned by Seller but is owned, controlled or licensed by Aerojet (the “Licensed Intellectual Property”), to use all Licensed Intellectual Property solely in connection with the Business (the “Pharmaceutical Field”). Such license shall be exclusive, even as to Aerojet. For purposes of this Section 7.10, “use,” includes, without limitation, make, have made, reproduce, display or perform (publicly or otherwise), prepare derivative works based on, offer for sale, sell, distribute, import, disclose, license, sublicense, dispose of, and otherwise exploit, solely in connection with the Business. Aerojet covenants not to license any Licensed Intellectual Property to any Third Party in the Pharmaceutical Field and not to assert, enforce or otherwise exercise any rights in the Pharmaceutical Field with respect to the Licensed Intellectual Property. Notwithstanding the provisions of Section 3.5, if Purchaser is unable to assert or enforce any Licensed Intellectual Property rights in the Pharmaceutical Field against a Third Party, Aerojet agrees to cooperate fully and as necessary, at Purchaser’s expense, to pursue such assertion or enforcement, including, without limitation, by joining as a party plaintiff, giving Purchaser the authority to institute and prosecute such assertion or enforcement, executing such documents as Purchaser may reasonably request in connection therewith and, upon the request of Purchaser, making available at reasonable times and under appropriate conditions all relevant personnel, records, papers, information, samples and other similar materials in the possession of Aerojet. If Purchaser still does not have the authority to assert or enforce such rights against the Third Party, Aerojet agrees to initiate proceedings, at Purchaser’s expense, against such Third Party in the name of Aerojet. Purchaser shall have the right to control, using counsel of Purchaser’s choice, any such assertion or enforcement, including without limitation settlement discussions relating to, and any declaratory judgment action arising from such enforcement; provided, however, that Purchaser shall be responsible for all of the costs and expenses of such assertion, enforcement, settlement, settlement discussions or declaratory judgment, and Purchaser (and its assigns) shall not, unless first obtaining Aerojet’s written consent, make any such assertion, enforcement or settlement, or enter into settlement discussions or seek any declaratory judgment, that would in any way alter, change, reduce, diminish, or otherwise impact Aerojet’s rights in the Licensed Intellectual Property outside of the Pharmaceutical Field.

48

Exhibit 2.1

     7.11 No Solicitation.

          Until the earlier of (a) the Closing and (b) the termination of this Agreement pursuant to its terms, no Seller Party shall, and each Seller Party shall cause its representatives not to, directly or indirectly, (i) initiate, solicit or encourage (including by way of furnishing information regarding the Business or the Purchased Assets or Assumed Liabilities) any inquiries, or make any statements to Third Parties which may reasonably be expected to lead to any proposal concerning the sale of the Business or the Purchased Assets or Assumed Liabilities (whether by way of merger, purchase of capital shares, purchase of assets or otherwise) (a “Competing Transaction”); or (ii) hold any discussions or enter into any agreements with, or provide any information or respond to, any Third Party concerning a proposed Competing Transaction or cooperate in any way with, agree to, assist or participate in, solicit, consider, entertain, facilitate or encourage any effort or attempt by any Third Party to do or seek any of the foregoing.

     7.12 Certain Notifications.

          From the date of this Agreement until the Closing, with respect to the Business, each Seller Party shall promptly notify Purchaser in writing regarding any:

          (a) any circumstance or event that could reasonably be expected to have a Material Adverse Effect on the Business;

          (b) fact, circumstance, event, or action by any Seller Party (i) which, if known on the date of this Agreement, would have been required to be disclosed in or pursuant to this Agreement; or (ii) the existence, occurrence, or taking of which would result in any of the representations and warranties of any Seller Party contained in this Agreement or in any Transaction Document not being true and correct when made or at Closing;

          (c) breach of any covenant or obligation of any Seller Party hereunder; and

          (d) circumstance or event which will result in, or could reasonably be expected to result in, the failure of any Seller Party to timely satisfy any of the closing conditions specified in Article IX of this Agreement.

     7.13 Seller Merger into Aerojet.

          Purchaser has reviewed those documents attached hereto as Exhibit K (the “Merger Documents”) related to the merger of Seller into Aerojet, with Aerojet as the surviving entity (the “Merger”). During the Standstill Period, no Seller Party shall approve or consummate a transaction involving the transfer of the Purchased Assets or the Business (by way of merger, asset acquisition or otherwise) other than the Merger on the terms and conditions set forth in the Merger Documents except after Purchaser has reviewed, commented on and approved in writing all of the agreements to be entered into in connection with any such transaction (including any substantive revisions to the Merger Documents) and the implementation of such agreements and such transactions; provided that Purchaser’s review and approval of such agreements and such transactions shall not be unreasonably withheld or delayed.

49

Exhibit 2.1

     7.14 Release From Pre-Closing Environmental Liabilities.

          Seller Parties shall use their commercially reasonable best efforts to obtain on or before the Closing a written acknowledgment and release from the United States Environmental Protection Agency and the California Department of Toxics Substances Control stating that Purchaser is not, and by its acquisition of the Purchased Assets and the operation of the Business following the Closing will not become, responsible for any Pre-Closing Environmental Liabilities, including without limitation those liabilities identified under the Partial Consent Decree. If such acknowledgment and release is not obtained on or before Closing, Seller Parties shall continue to use their commercially reasonable best efforts following Closing to obtain such acknowledgment and release as promptly as practicable following the Closing. Purchaser shall assist Seller Parties in all such efforts. Notwithstanding the foregoing, if despite such commercially reasonable best efforts by Seller Parties, such acknowledgement and release is not obtained (before or after the Closing), Seller Parties shall have no liability to Purchaser or its Affiliates for such failure and no such failure shall in any way delay the timing of the Closing.

     7.15 Consents.

          As promptly as possible after the date of this Agreement and prior to Closing, Seller shall use its commercially reasonable efforts to obtain all Required Consents. Purchaser shall not be required to agree to any material changes in, or the imposition of any material condition to the transfer to Purchaser of, any Contract or Governmental Permit or expend any material funds or incur any other burden as a condition to Seller obtaining any Required Consent.

     7.16 Parent Guaranty.

          On the Closing Date, Parent shall enter into the Guaranty in substantially the form set forth in Exhibit L (the “Guaranty”).

     7.17 Efforts to Close.

          Each of the Parties hereto agrees to use commercially reasonable best efforts to bring about the satisfaction of the conditions required to be performed by it under this Agreement prior to and at the Closing.

     7.18 Survey Disapproved Items

          The Parties acknowledge that Purchaser has not been delivered the Survey prior to the execution hereof, which Seller shall provide at least twenty (20) days prior to the Closing. Purchaser shall have seven (7) days after the date Purchaser has received the Survey to deliver to Seller written notice (“Purchaser’s Survey Notice”) of any encroachments or encumbrances on title shown on such Survey disapproved by Purchaser (“Disapproved Items”). The Parties agree that Disapproved Items shall not include any encroachment or encumbrance (i) set forth on Schedule 4.4(a), Schedule 4.5(b), or Schedule 4.5(g) hereto; (ii) on the preliminary title report dated June 1, 2005 from First American Title, a copy of which was provided to Purchaser’s counsel prior to the date hereof; (iii) that constitute Permitted Liens, or (iv) that individually or in the aggregate, does not materially interfere with the use of Leased Property for the Business as currently conducted. Purchaser’s failure to timely deliver Purchaser’s Survey Notice shall be

50

Exhibit 2.1

deemed to be Purchaser’s approval of any matters so disclosed. If Purchaser timely notifies Seller of Disapproved Items and all or some of the Disapproved Items are not cured or deleted as exceptions to title prior to the Closing, such Disapproved Items shall be a Purchaser Indemnity Claim pursuant to Section 11.1 hereof. Seller’s failure to cure or delete any Disapproved Items shall not be deemed to be a breach of this Agreement by Seller or entitle Purchaser to any offset against the Purchase Price.

     7.19 PolyFox Intellectual Property.

          The Parties shall use their respective commercially reasonable efforts to obtain the necessary governmental consents, if any, required to (i) effectuate the transfer of the Polyfox Intellectual Property to Purchaser on the Closing Date, and (ii) enter into the Polyfox License. To the extent such required consents have not been received prior to the Closing Date, the Parties agree that pending such consents, Aerojet will license to Purchaser the rights under the Polyfox Intellectual Property in all fields (subject to the terms of the Omnova Licensing Agreement) other than Reserved Field (as defined in Exhibit J attached hereto) (including fine chemicals for use in life sciences). The form of such license to Purchaser shall be such that no consents will be required (e.g. no right to manufacture).

ARTICLE VIII

POST CLOSING COVENANTS

     8.1 Access to Books and Records; Seller Party Confidentiality.

          (a) For a period of five years after the Closing Date or for such longer period of time as may be required to comply with Section 8.2, each Party hereto shall, upon reasonable notice, afford each of the other Parties with reasonable access to the books and records of such Party related to Seller, the Business, the Purchased Assets or the Assumed Liabilities during normal business hours in the event that such access is required to determine any matter related to the requesting Party’s rights and obligations hereunder or with respect to compliance with any requirements of any Governmental Authority or any other obligation of the requesting Party.

          (b) All non-public information regarding Purchaser made available or disclosed by Purchaser to any Seller Party or their respective agents in connection with this Agreement or the Transaction shall be deemed “Confidential Information” hereunder. No Seller Party shall, without the prior written consent of Purchaser, disclose to any Third Party (except such Seller Party’s third party advisors or except as required by Law or Order and only after compliance with the following sentence) or use any Confidential Information for any purpose other than compliance with Section 8.2. In the event that a Seller Party is required by Law or Order to disclose any of the Confidential Information, such Seller Party will notify Purchaser as soon as practicable (unless prohibited by Law) so that Purchaser may seek an appropriate protective order or other appropriate remedy or, in Purchaser’s sole discretion, waive compliance with the terms of this Section 8.1 (and if Purchaser seeks such an order, such Seller Party will provide such cooperation as Purchaser shall reasonably request). Upon Purchaser’s written request,

51

Exhibit 2.1

each Seller Party shall either return to Purchaser or certify destruction of all documentation containing Confidential Information. Confidential Information shall not include (i) any information that is known by any Seller Party or the general public at the time of disclosure or thereafter becomes known to the general public through no act of any Seller Party in violation of this Agreement, (ii) is independently developed by a Seller Party, (iii) is disclosed to a Seller Party by a Third Party without, to Seller’s knowledge, any breach of confidentiality obligation to Purchaser, or (iv) is approved for disclosure by the prior written consent of Purchaser. This provision shall survive (i) the termination of this Agreement for a period of two (2) years following the date of such termination or (ii) for a period of two (2) years following the termination of the compliance obligations under Section 8.2, whichever is longer.

     8.2 Cooperation on Tax Matters; Tax Reporting Consistent.

          (a) The Parties agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable and without cost to the other Party, such information (including access to books and records) and assistance, including assistance from employees of the Business, relating to the Business as is reasonably necessary for the filing of any federal, state or local return (including any report required pursuant to Section 6043 of the Code and all Treasury Regulations promulgated thereunder), for the preparation for any audit, and for the prosecution or defense of any claim, suit or proceeding relating to any proposed adjustment of any Tax for which either Party is liable under this Agreement (“Tax Contest”). The Parties agree to retain or cause to be retained all books and records pertinent to the Business until the applicable period for assessment under applicable law (giving effect to any and all extensions or waivers) has expired, and to abide by or cause the abidance with all record retention agreements entered into with any Governmental Authority. Purchaser shall give Seller reasonable notice prior to transferring, discarding or destroying any such books and records relating to Tax matters and, if Seller so requests, Purchaser shall allow Seller to take possession of such books and records. The Parties shall cooperate with each other in the conduct of any audit or other proceedings involving the Business for any Tax purposes and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this Section 8.2.

          (b) Notwithstanding any provision in Section 11.3 to the contrary (but specifically including the limitations set forth in Section 11.5), the provisions of this Section 8.2 (b) will apply with respect to any audit, proceeding or claim by any Tax Authority that relates to taxes assessed by such Tax Authority for which the other Party is financially responsible.

          (i) Each Party receiving a notice of any audit, proceeding or claim by any Tax Authority (such Party is referred to herein as the “Notified Party”) will promptly notify the other Party of, and reasonably coordinate with the other Party, the response to and settlement of, any such audit, proceeding or claim for Tax by a Tax Authority for which the other Party is financially responsible hereunder (such other Party is referred to herein as the “Financially Responsible Party”). With respect to any claim arising out of a form or return signed by a Party to this Agreement, such Party will have the right to

52

Exhibit 2.1

control the response to and settlement of the claim, except that the Financially Responsible Party will have the right to participate in the responses and settlements commensurate with its potential economic responsibilities and liabilities for Taxes under this Agreement and no responses or settlements shall be proffered by the Notified Party without the prior written consent of the Financially Responsible Party, which consent shall not be unreasonably withheld or delayed. Each Party will provide any information related to such claim reasonably requested by the other Party not otherwise prohibited from disclosure under Law.

          (ii) The Financially Responsible Party may direct the Party that has the right to control the response to or settlement of any claim under this Section 8.2(b) to challenge the imposition of any such Tax liability (if such challenge is not precluded under local Law). If a Party requests the other to challenge the imposition of any Tax liability, the requesting Party will reimburse the other for all reasonable legal, accounting and other professional fees and expenses it incurs in connection with such challenge. If such a challenge cannot be perfected without pre-paying the Tax at issue, then the Financially Responsible Party wishing to challenge the imposition of the Tax must pay such Tax to the other Party which shall immediately be paid to the Tax Authority or, if appropriate, to the Tax Authority directly. Neither Party will enter into a settlement of any Tax liability that creates a binding financial obligation for the other Party without the other Party’s prior written consent, which consent shall not be unreasonably withheld or delayed.

     8.3 No Further Investigation; Environmental Cooperation.

          (a) With respect to the Leased Property, and the property subject to the Warehouse Lease, on and after the Closing Date, Purchaser, on behalf of itself and its Affiliates and its successors and assigns, agrees not to, and agrees not to enter into any agreement that would permit its successors or assigns or the successors or assigns of its Affiliates to, (A) take any voluntary action, including any sampling of the soil or groundwater, or to initiate or encourage any action by any third party, including any Governmental Authority or third party, which could reasonably be expected to lead to a claim or demand by such Governmental Authority or third party under any Environmental Law; provided that if any Law, including any Environmental Law, with respect to the Leased Property or the Owned Property, or the defense of any Third Party Claim against Purchaser, requires Purchaser or any of its Affiliates, successors or assigns to investigate, take action, initiate or encourage any such action, Purchaser will promptly notify Seller of such requirement and the content and timing of any action that Purchaser (or their respective Affiliates, successors or assigns) proposes to take, and the Parties shall consult with each other regarding the satisfaction of such requirement; or (B) use or store any of the chemicals set forth on Schedule 8.3 hereto.

          (b) In addition to, and not in derogation of, any other provisions of this Agreement, Purchaser, on behalf of itself, its Affiliates, successors and assigns, agrees that it shall provide Seller Parties and their respective representatives reasonable access to the premises of the Business, to their respective books and records and to their respective appropriate personnel (as are relevant to Seller’s inquiry) for the sole purposes of

53

Exhibit 2.1

proving a liability is an Assumed Environmental Liability or is otherwise not a Pre-Closing Environmental Liability. Seller shall provide Purchaser with at least 10 days written notice of Purchaser’s intent to obtain information related to Assumed Environmental Liability pursuant to this provision and shall specifically identify the nature of Seller’s inquiry and the specific information sought in writing so as to minimize the disruption of the Business. Purchaser, on behalf of itself, its Affiliates, successors and assigns, agrees that (i) Purchaser shall provide Seller Parties with copies of any Governmental Authority audit findings regarding any Releases or compliance with any Environmental Law; and (ii) Purchaser shall provide Seller Parties all relevant information regarding their respective use of Hazardous Substances, including, without limitation, Material Safety Data Sheet (MSDS) on or about the Leased Property.

     8.4 Guarantees for Benefit of the Business.

          Following Closing, Purchaser shall use commercially reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and otherwise to remove or replace Seller or any Affiliate of Seller as the guarantor, maker or obligor on all guarantees for borrowed money, letters of credit, customs bonds and similar instruments in the name of the Business outstanding on the Closing Date other than those relating to Excluded Liabilities no later than 120 days following the Closing Date. Seller Parties shall use commercially reasonable efforts to assist Purchaser in these endeavors. Purchaser will indemnify Seller against any and all liabilities of Seller or any such Affiliate (i) resulting from a call on any such obligation prior to such removal or replacement of Seller or such Affiliate, as applicable, or (ii) arising out of any default by Purchaser in the performance of the obligations contained in this Section 8.4; provided, however, that, so long as Purchaser has used commercially reasonable efforts in this regard, Purchaser shall have no liability to Seller Parties solely as the result of any failure to so remove or replace Seller or any Affiliate of Seller as the guarantor, maker or obligor on any such guarantee. The indemnification of Seller under this Section 8.4 will be governed by the indemnification provisions set forth in ARTICLE XI hereto.

     8.5 Aerojet Trade Name and Trademarks.

     On the Closing Date, Aerojet shall enter into a trademark license agreement with Purchaser for the use of the Aerojet name in connection with the Business during a period not to exceed fifteen (15) months after the Closing Date, on a royalty-free basis and in the form set forth in Exhibit M (the “Trademark License Agreement”).

INDEMNIFICATION; SURVIVAL OF
REPRESENTATIONS AND WARRANTIES

     11.1 Indemnity Obligations of Seller Parties.

          Subject to the provisions of this ARTICLE XI, from and after the Closing Date each Seller Party, jointly and severally, hereby agrees to indemnify, defend and hold Purchaser (which for purposes of this Article shall include all directors, officers, employees, agents, Affiliates and representatives of Purchaser) harmless from, and to reimburse Purchaser for, any Purchaser Indemnity Claim arising under the terms and conditions of this Agreement. For purposes of this Agreement, the term “Purchaser Indemnity Claim” shall mean any and all losses, damages, amounts paid in settlement, deficiencies, claims, liabilities, obligations, suits, actions, proceedings, fees, penalties, Remedial Action costs, interest costs and expenses of any nature whatsoever, including reasonable attorney’s fees, court costs and other out-of-pocket costs and expenses of preparing, investigating, defending and/or settling the foregoing (collectively, “Losses”), incurred or sustained by Purchaser resulting from (i) subject to Section 11.4 hereof, any breach of any representation and warranty of any Seller Party contained in this Agreement; (ii) any breach or non-fulfillment of, or any failure to perform, any of the covenants, agreements

59

Exhibit 2.1

or undertakings of any Seller Party that are contained in this Agreement; (iii) any Excluded Liabilities; or (iv) any Disapproved Item.

     11.2 Indemnity Obligations of Purchaser.

          Subject to the provisions of this ARTICLE XI, from and after the Closing Date Purchaser hereby agrees to indemnify, defend and hold Seller (which for purposes of this Article shall include all directors, officers, partners, employees, agents, Affiliates and representatives of Seller) harmless from, and to reimburse Seller for, any Seller Indemnity Claims arising under the terms and conditions of this Agreement. For purposes of this Agreement, the term “Seller Indemnity Claim” shall mean any Losses incurred by Seller or any of Seller’s Affiliates resulting from (i) subject to Section 11.4 hereof, any breach of any representation and warranty of Purchaser which is contained in this Agreement; (ii) any breach or non-fulfillment of, or failure to perform, any of the covenants, agreements or undertakings of Purchaser which are contained in this Agreement; (iii) the Assumed Liabilities; or (iv) the Assumed Environmental Liabilities.

     11.3 Notification of Claims.

          (a) Except as otherwise provided in Section 8.2(b) hereof, subject to the provisions of this ARTICLE XI, in the event of the occurrence of an event which any Party (the “Indemnified Party”) asserts constitutes a Purchaser Indemnity Claim or a Seller Indemnity Claim, as applicable, such Party shall provide the indemnifying Party with prompt notice of such event and shall otherwise make available to the indemnifying Party all relevant information which is material to the claim, including information with respect to the availability of insurance coverage, and which is in the possession of the Indemnified Party. An Indemnified Party’s failure to give timely notice as provided above or to furnish the indemnifying Party with any relevant information shall not constitute a defense (in part or in whole) to any claim for indemnification by such Party, except and only to the extent that such failure shall result in any material prejudice to the indemnifying Party.

          (b) The indemnifying Party shall have a period of 60 days after the time of delivery of any such notice to object to the claim made in such notice. If the indemnifying Party does not object to the claim made in the Claim Notice in a written statement that is delivered to the Indemnified Party prior to the expiration of such 60-day period, such failure to so object shall be an irrevocable acknowledgment by the indemnifying Party that the Indemnified Party is entitled indemnification under Sections 11.1 or 11.2, as applicable, for the full amount of the Losses set forth in the such notice, subject to the Basket and Purchaser’s Cap or Seller’s Cap, as applicable.

          (c) If such event involves the claim of any third party (a “Third Party Claim”), the indemnifying Party shall have the right to elect to join in the defense, settlement, adjustment or compromise of any such Third Party Claim, and to employ counsel to assist such Indemnified Party in connection with the handling of such claim, at the sole expense of the indemnifying Party, and no such claim shall be settled, adjusted or compromised, or the defense thereof terminated, without the prior consent of the indemnifying Party unless and until the indemnifying Party shall have failed, after the lapse of a reasonable period of time, but in no event more than 30 days after written notice to it of the Third Party Claim, to join in the defense, settlement, adjustment or

60

Exhibit 2.1

compromise of the same. Upon receipt of written notice of any Third Party Claim, the Indemnified Party shall promptly, but in no event later than 15 days prior to the date a response or answer thereto is due (unless a response or answer is due within fewer than 15 days from the date the Indemnified Party received notice thereof and then so long as reasonably possible prior to the due date thereof), inform the indemnifying Party in writing thereof. Any indemnifying Party may elect, at such Party’s sole expense, to assume control of the defense, settlement, adjustment or compromise of any Third Party Claim, with counsel reasonably acceptable to each Indemnified Party, insofar as such claim relates to the liability of the indemnifying Party, provided that such indemnifying Party shall obtain the consent of all Indemnified Parties (which consent shall be deemed given if any request for consent is not responded to within ten Business Days) before entering into any settlement, adjustment or compromise of such claims, or ceasing to defend against such claims, if as a result thereof, or pursuant thereto, (i) there would be imposed on an Indemnified Party any material liability or obligation not covered by the indemnity obligations of the indemnifying parties under this Agreement (including, without limitation, any injunctive relief or other remedy), (ii) any Indemnified Party would be required to admit any liability on the part of such Indemnified Party or (iii) the Indemnified Parties would not receive an unconditional release of all applicable indemnified claims. In connection with any Third Party Claim, the Indemnified Party, or the indemnifying Party if it has assumed the defense of such claim pursuant to the preceding sentence, shall diligently pursue the defense of such Third Party Claim and the Indemnified Party shall cooperate with the indemnifying Party in connection with such claim, make available personnel, witnesses, books and records relevant thereto and grant such authorizations to the agents, representatives and counsel of the indemnifying Party as the indemnifying Party may request.

          (d) In case the indemnifying Party objects in writing to any claim or claims made in any such notice in accordance with this Section 11.3, the Parties shall attempt in good faith to agree upon the rights of the respective Parties with respect to each of such claim or claims. If no such agreement can be reached after good faith negotiation, such dispute shall be resolved in accordance with Sections 12.2 through 12.4.

     11.4 Survival.

          All representations and warranties contained herein, and the rights of the Parties to seek indemnification with respect thereto, shall survive the Closing and shall expire at the close of business the second anniversary of the Closing Date, except that representations contained in Section 4.9 and Section 4.14 shall survive until the expiration of the respective statute of limitations applicable to the matters described therein and representations contained in Section 4.4(a) and Section 4.5(b) shall survive indefinitely.

     11.5 Limitations.

          (a) An indemnifying Party will not have liability under Section 11.1(i) or Section 11.2(i), as the case may be, unless the claim exceeds the Threshold, and until the aggregate amount of liability actually incurred by the Indemnified Party with respect to all Purchaser Indemnity Claims or Seller Indemnity Claims (in each case that exceed the Threshold, if applicable), as the case may be, exceeds one and a half percent (1.5%)

61

Exhibit 2.1

of the Purchase Price (the “Basket”), in which event, the indemnifying Party will be required to pay the entire amount of such Purchaser Indemnity Claims or Seller Indemnity Claims in excess of the Basket. In addition to the foregoing, except as set forth in Section 11.5(b), the maximum aggregate amount for which indemnification with respect to Section 11.1(i) may be sought will be 50% of the Purchase Price (“Seller’s Cap”) and the maximum aggregate amount for which indemnification with respect to Section 11.2(i) may be sought will be 50% of the Purchase Price (“Purchaser’s Cap”); provided, however, (i) Seller’s obligation to indemnify Purchaser for any Pre-Closing Environmental Liability shall not be subject to the Threshold or Basket, (ii) Seller’s obligation to indemnify Purchaser for any Losses under this Article XI with respect to any Pre-Closing Environmental Liability shall not be subject to Seller’s Cap and shall be limited only (x) to the extent Purchaser contributed to or exacerbated the condition or circumstance forming the basis of such Losses which are not caused by Purchaser or its Affiliates and (y) to the most cost-effective, remedial alternative that is protective of human health and the environment and is consistent with and meets the requirements of any applicable Environmental Law and any Governmental Authority based upon the use of the property as industrial property, (iii) Seller’s obligation to indemnify Purchaser for any Losses under this Article XI with respect to any Retained Taxes shall not be subject to Seller’s Cap, (iv) Seller’s obligation to indemnify Purchaser for any Losses under this Article XI with respect to any Excluded Liabilities shall not be subject to the Threshold or Basket or Seller’s Cap; and (v) Seller’s obligation to indemnify Purchaser for any Losses arising out of the breach of any covenants of Seller contained herein shall not be subject to the Threshold or Basket or Seller’s Cap; and further provided that Purchaser’s obligation to indemnify Seller for any Assumed Environmental Liability shall not be subject to the Threshold or Basket or Purchaser’s Cap; (ii) Purchaser’s obligation to indemnify Seller for any Losses under this Article XI with respect to any Assumed Liabilities shall not be subject to the Threshold or Basket or Purchaser’s Cap; and (iii) Purchaser’s obligation to indemnify Seller for any Losses arising out of the breach of any covenants of Purchaser contained herein shall not be subject to the Threshold or Basket or Purchaser’s Cap.

          (b) Notwithstanding anything to the contrary contained herein, no Seller Party nor any of their respective Affiliates shall have any liability under this ARTICLE XI for any Purchaser Indemnity Claim to the extent arising out of or in connection with any action (whether the taking of soil or groundwater samples or otherwise) prohibited by Section 8.3, whether by Purchaser or any other Person, including any subsequent owner or operator of any part of the Business.

          (c) The amount for which indemnification may be sought for any Purchaser Indemnity Claim or Seller Indemnity Claim shall (i) be net of any amounts recovered or recoverable by the Indemnified Party or an Affiliate of the Indemnified Party under applicable insurance policies or otherwise, and (ii) be (A) reduced to take into account any net Tax benefit realized by the Indemnified Party arising from the incurrence or payment of amounts for which indemnification is claimed and (B) increased to take into account any net Tax cost incurred by the Indemnified Party arising from the receipt of indemnity payments hereunder (including any Tax resulting from the payment under this subclause (B)). In computing the amount of any such Tax or Tax

62

Exhibit 2.1

benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt or accrual of any indemnity payment hereunder or incurring or paying any indemnified claim. Any indemnity payment hereunder shall initially be made without regard to this Section 11.5(c) and shall be increased or reduced to reflect any such net Tax cost (including gross-up) or net Tax benefit only after the Indemnified Party has actually realized such cost or benefit. For the purposes of this Agreement, an Indemnified Party shall be deemed to have “actually realized” a net Tax cost or a net Tax benefit to the extent that, and at such time as, the amount of Taxes payable by such Indemnified Party is increased above or reduced below (including the receipt by any Indemnified Party of a refund of Taxes), as the case may be, the amount of Taxes that such Indemnified Party would be required to pay but for the receipt or accrual of the indemnity payment or the incurrence or payment of such indemnified claim.

          (d) No claims for Indemnification shall include indirect, consequential, punitive, special or exemplary damages or any claim for a multiplier effect or any capitalization of out-of-pocket expenses or lost profits, provided, however, that the foregoing shall not be construed to preclude recovery by the Indemnified Party in respect of Losses directly incurred from Third-Party Claims. Both Parties shall use commercially reasonable efforts to mitigate their damages. No Indemnified Party shall be indemnified under this ARTICLE XI for any matter to the extent that such Indemnified Party has been compensated for such matter pursuant to the Purchase Price adjustment contained in Section 3.1.

          (e) The Parties agree that, following the Closing, the indemnification and other provisions set forth in this ARTICLE XI will be the sole and exclusive remedy of Purchaser against Seller, on the one hand, and of Seller against Purchaser, on the other hand, arising out of this Agreement; provided, however, that this Section 11.5(d) shall not preclude a Party from bringing an action for specific performance or other equitable remedy to require a Party to perform its obligations under this Agreement or any agreement referenced herein. Notwithstanding the foregoing, nothing herein will eliminate the availability to the Parties of any equitable remedies with respect to any dispute that may arise under this Agreement or limit any claim based upon fraud.

     12.4 Waiver of Jury Trial.

          EACH PARTY TO THIS AGREEMENT WAIVES ITS RESPECTIVE RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTION OR ANY DEALINGS BETWEEN ANY OF THE PARTIES HERETO RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.

66

Exhibit 2.1

     12.6 Other Definitional and Interpretive Matters.

     Unless otherwise expressly provided, for purposes of this Agreement, the following rules of interpretation shall apply:

          (a) Calculation of Time Period. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day.

          (b) Gender and Number. Any reference in this Agreement to gender shall include all genders, and words imparting the singular number only shall include the plural and vice versa.

          (c) Headings. The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. All references in this Agreement to any “Section” are to the corresponding Section of this Agreement unless otherwise specified.

          (d) Herein. The words such as “herein,” “hereinafter,” “hereof,” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires.

          (e) Including. The word “including” or any variation thereof means “including, without limitation” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it.

          (f) Efforts. The obligation of a Party to use reasonable best efforts or commercially reasonable efforts to accomplish an objective does require a reasonable expenditure of funds or the incurrence of a reasonable liability on the part of the obligated Party based on the facts and circumstances of each situation requiring such efforts.

     12.7 Schedules and Updated Schedules.

          Disclosure of information in any of the Schedules shall be deemed to be disclosure of such information in any other relevant Schedule and with respect to any relevant representation or warranty in this Agreement. Except as expressly provided in this Agreement, no schedule or exhibit may be updated, supplemented, modified or otherwise changed without the written consent of Purchaser and each Seller Party. Any schedule permitted to be updated pursuant to the express terms of this Agreement will be updated by the appropriate party in good faith.

67

     12.8 Amendments; Waiver; Assignment.

          This Agreement, including, without limitation, the Schedules, the attachments or any other document or certificate delivered pursuant hereto, may be amended, modified, superseded or canceled and any of the terms, provisions and conditions hereof may be waived only by a written instrument executed by all of the Parties hereto. Notice or knowledge of any matter shall not constitute a waiver of any representation or warranty with respect to such matter. The waiver by any Party of any breach of any provision shall not be construed as a waiver of any other provision by such Party. Each Party shall have the right to waive fulfillment of a condition or covenant or compliance with a representation or warranty of which it is the beneficiary. This Agreement and all or any rights hereunder may be assigned by either Party upon prior notice to the other Party; provided, however, that no such assignment shall relieve the assigning Party from its obligations, representations, warranties, indemnities or covenants under this Agreement and the other Transaction Documents and no such assignment and assumption shall diminish the other Party’s rights, remedies and defenses under this Agreement or applicable law generally against the assigning Party or its assignee, as the case may be. In the event that Purchaser so assigns this Agreement and/or any or all rights hereunder, then Purchaser shall enter into the Guaranty in substantially the form set forth in Exhibit O (the “Purchaser Guaranty”).

     12.9 Entire Agreement; Beneficiaries; No Third Party Beneficiaries.

          This Agreement, the Schedules and Exhibits hereto, the Confidentiality Agreement and the Transaction Documents constitute the entire agreement among the Parties hereto and supersedes all prior agreements, understandings and arrangements, oral or written, between the Parties hereto with respect to the subject matter hereof. This Agreement inures to the benefit of and shall be binding on and enforceable by each of the Parties hereto or any of them, their respective representatives, successors, permitted assigns and the indemnitees described in Section 11.1 and Section 11.2. Nothing in this Agreement, express or implied, is intended to or shall (a) confer on any Person other than the Parties hereto and their respective successors or assigns any rights (including third-party beneficiary rights), remedies, obligations or liabilities under or by reason of this Agreement or (b) constitute the Parties hereto as partners or as participants in a joint venture.

     12.10 Currency.

Exhibit 2.1

     12.12 Severability.

          In the event any provision of this Agreement or the application thereof becomes or is declared by a court of competent jurisdiction illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and shall not be affected thereby and each provision hereof shall be valid and enforced to the fullest extent permitted by law. The Parties further agree to replace such illegal, void or unenforceable provision of this Agreement with a legal, valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such illegal, void or unenforceable provision

     12.13 Schedules.

          The Parties acknowledge and agree that (i) the Schedules to this Agreement may include certain items and information solely for informational purposes for the convenience of Purchaser, (ii) the disclosure by Seller of any matter in the Schedules shall not be deemed to constitute an acknowledgment by Seller that the matter is required to be disclosed by the terms of this Agreement or that the matter is material, and (iii) disclosure in one Schedule, to the extent that such disclosure would be reasonably appropriate in the context in which it would be made, will be deemed to be an exception to any representation and included on such relevant exception Schedule.

     12.14 Other Remedies.

          Except as otherwise provided herein (including, without limitation Sections 11.5(c) and 11.5(d)), any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.
