Effective as of the Closing Date, the Active Constar Employees will cease to earn benefits under the Crown Retirement Plans and the Constar Group will establish the Constar Retirement Plans for the benefit of the Active Constar Employees. The Constar Retirement Plans will provide benefits for a period of one year after the Closing Date that are at least substantially equivalent in all Material Features (except for the Supplemental Pension Plan provisions of the Crown Salaried Pension Plan) to those provided under the corresponding Crown Retirement Plans immediately before the Closing Date. Except as specifically provided under Section 3.3 and notwithstanding Section 2.2, the Crown Retirement Plans will retain all liabilities and assets related to retirement benefits earned by Active Constar Employees and Former Constar Employees prior to the Closing Date. (b) Governmental Filings. Crown and Constar shall cooperate to make any and all filings required with respect to the Crown Retirement Plans and the Constar Retirement Plans under the Code or ERISA in connection with the Offering or the asset transfers described in this Article III in a timely manner. (c) Determination Letters. Constar shall apply to the Internal Revenue Service for favorable determination letters with respect to the tax-qualified status of the Constar Retirement Plans as soon as practicable after the Closing Date, and Constar, consistent with the terms of this Agreement, shall make such amendments to such Plans as may be required by the Internal Revenue Service in order for Constar to receive favorable determination letters with respect to these Plans. (d) Terms of Participation—Active Constar Employees. Each Constar Retirement Plan shall provide that all service, compensation, and other benefit-affecting determinations that, as of the Closing Date, were recognized under the corresponding Crown Retirement Plan with respect to Active Constar Employees (for periods immediately before the Closing Date) shall, as of immediately after the Closing Date, receive full recognition, credit and validity and be taken into account under such Constar Retirement Plan to the same extent as if such items occurred under such Constar Retirement Plan, except to the extent that duplication of benefits would result. (e) Beneficiary Designations. All beneficiary designations made by Active Constar Employees or their respective alternate payees with respect to the Crown Retirement Plans shall be transferred to and be in full force and effect under the corresponding Constar Retirement Plans until such beneficiary designations are replaced or revoked by the individual who made such beneficiary designation.

Constar Employees, their Beneficiaries and their respective alternate payees immediately after the Closing Date that are at least substantially equivalent in all Material Features to those provided under the Crown Pension Plans immediately before the Closing Date. For purposes of eligibility (including early retirement eligibility), vesting and benefit accrual, all service recognized under the corresponding Crown Pension Plan (for periods immediately before the Closing Date) shall, as of immediately after the Closing Date be recognized and taken into account under the appropriate Constar Pension Plan. For purposes of benefit accrual, all compensation recognized under the corresponding Crown Pension Plan (for periods immediately before the Closing Date) shall, as of immediately after the Closing Date, be recognized and taken into account under the appropriate Constar Pension Plan.

Following the Closing Date, and notwithstanding Section 2.2, the Crown Pension Plans shall retain all liabilities and assets related to Active Constar Employees and Former Constar Employees earned prior to the Closing Date. (d) PBGC Intervention. Notwithstanding any provision of this Agreement to the contrary, in the event that at any time the Pension Benefit Guaranty Corporation (PBGC) or any other Governmental Authority asserts that the Offering may provide justification for the PBGC to seek termination of any Crown Pension Plan or Constar Pension Plan under ERISA or otherwise asserts that the Offering may increase unreasonably the long-run loss to the PBGC (within the meaning of ERISA section 4042(a)(4)) with respect to any Crown Pension Plan or Constar Pension Plan, Crown may, in its sole discretion: (i) Enter into negotiations with the PBGC to resolve these issues and, upon satisfactorily resolving such issues, Constar shall fully comply with the terms of any agreement entered into by Crown with the PBGC; or (ii) Transfer all assets and liabilities with respect to Active Constar Employees and/or Former Constar Employees and their respective alternate payees arising prior to the Closing Date under the applicable Crown Pension Plan to the corresponding Constar Pension Plan in a manner acceptable to the PBGC.

Employees, their Beneficiaries and their respective alternate payees immediately after the Closing Date that are at least substantially equivalent in all Material Features to those provided under the Crown Savings Plans immediately before the Closing Date.

As soon as practicable after the Closing Date, Crown shall cause the accounts of the Active Constar Employees, their Beneficiaries and their respective alternate payees, if any, under the applicable Crown Savings Plan that are held by its related trust to be transferred to the Constar Savings Plan and its related trust, and Constar shall cause such transferred accounts to be accepted by such plan and trust. The transfer of such accounts shall be made: (A) in kind, to the extent the assets consist of investments in a Crown Common Stock fund and (B) otherwise in cash, interests in mutual funds, securities, or other property or in a combination thereof, as the Parties may agree, but, to the extent practicable, shall be invested initially in comparable investment options in the Constar Savings Plan as such accounts were invested immediately before the date of transfer. Any outstanding loan balances under any Crown Savings Plans to Active Constar Employees shall be transferred with the underlying accounts. (ii) Non-Employer Stock Funds. Effective immediately after the Closing Date, the Constar Savings Plan shall provide for both a Crown Common Stock fund and a Constar Common Stock fund as investment options. The Crown Common Stock fund in the Constar Savings Plan shall be referred to as the Non-Employer Stock Fund. The Non-Employer Stock Fund will be maintained under the Constar Savings Plan until at least December 31, 2004, or for such longer period as the applicable Constar Savings Plan fiduciaries determine the Non-Employer Stock Fund to be an appropriate investment under the Constar Savings Plan. The Constar Savings Plan shall provide that, after the Closing Date, no new contributions may be invested in, and no amounts may be transferred from other investment options to, the Non-Employer Stock Fund. The Constar Savings Plan shall provide that no earnings or dividends attributable to the Non-Employer Stock Fund may be reinvested in the Non-Employer Stock Fund. (iii) Provision of Disclosure Materials Relating to Non-Employer Stock Funds. Crown shall provide to Constar in a timely manner such proxy statements, annual reports, and other materials with respect to Crown stock held in the Non-Employer Stock Fund under the Constar Savings Plan as may be reasonably requested by Constar.

ARTICLE IV WELFARE PLANS Section 4.1 General Principles. (a) Assumption of Welfare Plan Liabilities. Effective as of the Closing Date, all Liabilities relating to Active Constar Employees and Former Constar Employees and their Beneficiaries under the Crown Welfare Plans shall cease to be Liabilities of Crown or the Crown Welfare Plans and shall be assumed by the Constar Group and the Constar Welfare Plans including, without limitation, retiree medical benefits. Except as specifically set forth in Sections 4.4 and 4.8, Constar shall not be entitled to assets associated with any Crown Welfare Plan. (b) Continuation of Elections. Constar shall cause the Constar Welfare Plans to recognize and maintain all coverage and contribution elections made by Active Constar Employees (and Former Constar Employees, if applicable) under the Crown Welfare Plans in effect for the period immediately before the Closing Date and shall apply such elections under the Constar Welfare Plans for the remainder of the period or periods for which such elections are by their terms applicable. Constar shall provide coverage to Active Constar Employees (and Former Constar Employees, if applicable) under the Constar Welfare Plans without the need to undergo a physical examination or otherwise provide evidence of insurability, will not impose pre-existing condition exclusions and will recognize and maintain all irrevocable assignments and elections made by Active Constar Employees (and Former Constar Employees, if applicable) in connection with any life insurance coverage under the Crown Welfare Plans. (c) Continuation of Co-Payments. Constar shall cause the Constar Welfare Plans to recognize and give credit for all amounts applied to deductibles, out-of-pocket maximums, and other applicable benefit coverage limits for expenses that have been incurred by Active Constar Employees (and Former Constar Employees, if applicable) under the Crown Welfare Plans for the remainder of the benefit limit year in which the Closing Date occurs. (d) Continuation of Maximum Benefits. Constar shall cause the Constar Welfare Plans to recognize and give credit for all benefits paid to Active Constar Employees and Former Constar Employees under the Crown Welfare Plans, before and during the benefit limit year in which the Closing Date occurs, for purposes of determining when such persons have reached their lifetime maximum benefits under the Constar Welfare Plans. (e) COBRA and HIPAA Obligations. For the period before the Closing Date and for the period following the Closing Date that Crown is providing administrative services with respect to the Constar Welfare Plans pursuant to the terms of the Transition Services Agreement, Crown shall be responsible for administering compliance with the continuation coverage requirements for “group health plans” under Title X of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (COBRA), and the portability requirements under the Health Insurance Portability and Accountability Act of 1996, as amended (HIPAA), with respect to Active Constar Employees, Former Constar Employees and their Beneficiaries and shall be responsible for furnishing all necessary employee change notices with respect to

these persons in accordance with applicable Crown policies and procedures.

Section 4.2 Establishment of Welfare Plans. Effective as of the Closing Date, Constar shall take all actions necessary or appropriate to establish the Constar Welfare Plans to provide Active Constar Employees (and Former Constar Employees, if applicable) benefits that are identical in all Material Features to those benefits provided under the Crown Welfare Plans from time to time during the period that Crown is providing administrative services with respect to the Constar Welfare Plans pursuant to the terms of the Transition Services Agreement. Section 4.3 Vacation and Sick Pay Liabilities. Effective as of the Closing Date, Constar shall assume all Liabilities for vacation, sick leave and other paid time off in respect of all Active Constar Employees (and Former Constar Employees, if applicable) as of the Closing Date.

For the calendar year that includes the Closing Date, the Constar Cafeteria Plan shall recognize all elections, contributions and related claims by Active Constar Employees (and Former Constar Employees, if applicable) to flexible spending or dependent care assistance accounts under the Crown Cafeteria Plan. As soon as practicable after the close of such calendar year, Crown shall reimburse Constar for the aggregate contributions to such accounts withheld by Crown from Active Constar Employees (and Former Constar Employees, if applicable) prior to the Closing Date to the extent that Crown did not exhaust such contributions by providing benefits to Active Constar Employees (and Former Constar Employees, if applicable) prior to the Closing Date, or if benefits paid by Crown to Active Constar Employees (and Former Constar Employees, if applicable) prior to the Closing Date exceeds the contributions withheld by Crown from Active Constar Employees (and Former Constar Employees, if applicable), Constar shall reimburse Crown for such difference. Section 4.5 Severance. The Parties agree that, with respect to Active Constar Employees who, in connection with the Offering, cease to be employees of the Crown Group and become Employees of the Constar Group, such cessation shall not be deemed a severance of employment for purposes of any Plan that provides for the payment of severance, salary continuation or similar benefits. The Parties shall take all such action, including, but not limited to amending any Plan to give effect to the provisions of this Section 4.5. Section 4.6 Vendor Contracts. (a) Pre-Closing Date Negotiation. Before the Closing Date, Crown shall take such steps as are necessary under each ASO Contract, Group Insurance Policy and HMO

Agreement in existence as of the date of this Agreement to permit Constar to participate in the terms and conditions of such ASO Contract, Group Insurance Policy or HMO Agreement beginning immediately after the Closing Date. (b) Terms of Constar Participation. Crown shall determine, and shall promptly notify Constar of, the manner in which Constar’s participation in the terms and conditions of ASO Contracts, Group Insurance Policies and HMO Agreements, as set forth above is to be effectuated. Constar hereby authorizes Crown to act on its behalf to extend to Constar the terms and conditions of the ASO Contracts, Group Insurance Policies and HMO Agreements. Constar shall fully cooperate with Crown in such efforts. (c) Premium/Administration Rates. Crown and Constar shall use their reasonable best efforts to cause each of the insurance companies, HMOs, paid provider organizations and third-party administrators providing services and benefits under the Crown Welfare Plans and the Constar Welfare Plans to maintain the premium and/or administrative rates, based on the aggregate number of participants in both the Crown Welfare Plans, after the Closing Date, and the Constar Welfare Plans. (d) Management of the ASO Contracts, Group Insurance Policies and HMO Agreements. Constar shall be responsible, subject to the direction and control of Crown, for the management of the existing contractual and other arrangements pertaining to the administration of the Constar Welfare Plans. Immediately after the Closing Date, Constar shall be responsible for the management and control of the ASO contracts, Group Insurance Policies and HMO Agreements and other vendor contracts and relationships to the extent such contracts, policies and agreements apply to the Constar Welfare Plans. Notwithstanding the foregoing, nothing contained in this Section 4.6(d) shall permit Constar to direct any insurance carrier, third-party vendor or claims administrator with respect to any contractual arrangement, policy or agreement under any Crown Welfare Plan. Section 4.7 Workers’ Compensation and Unemployment Compensation. Effective as of the Closing Date, Constar shall assume all Liabilities for Active Constar Employees and Former Constar Employees related to any and all workers’ compensation and unemployment compensation matters under any law of any state, territory, or possession of the United States or the District of Columbia and Constar shall be fully responsible for the administration of all such claims. If Constar is unable to assume any of such Liabilities or the administration of any such claim because of the operation of applicable state law or for any other reason, Constar shall reimburse Crown for all such Liabilities. Section 4.8 Retiree Medical Benefits. Following the Closing Date, Crown shall continue to permit Former Constar Employees (and Active Constar Employees, who subsequently become eligible and elect to do so), to pay their portion of the cost of retiree medical benefits through a voluntary deduction from their benefit payments under the applicable Crown Pension Plan. Crown shall cause such deduction to be made and to be remitted to Constar within 30 days of when such amount would otherwise have been paid to such Former Constar Employee (or Active Constar Employee, if applicable).

ARTICLE V EXECUTIVE COMPENSATION PROGRAMS Section 5.1 Excess Benefit Plan. (a) Cessation of Participation. All Active Constar Employees shall cease to be eligible to participate in the Crown Excess Benefit Plan as of the Closing Date. (b) Retention of Liabilities. Notwithstanding any provision of this Agreement to the contrary, effective as of the Closing Date, the Crown Group shall retain all Liabilities in connection with the Crown Excess Benefit for Active Constar Employees (and Former Constar Employees, if applicable) and the Constar Group shall have no responsibility with respect to such Liabilities. Section 5.2 Incentive Plans. Constar shall assume all Liabilities for or related to Active Constar Employees (and Former Constar Employees, if applicable) payable under the Crown Incentive Plans with respect to the period prior to the Closing Date; provided, however, that Crown and Constar may jointly make such adjustments to the financial goals, targets, payments and forms of payment as they deem appropriate to reflect the Offering. As of the Closing Date, Constar shall establish the Constar Incentive Plan covering such of its Active Constar Employees as it in its sole discretion deems appropriate. Section 5.3 Supplemental Executive Retirement Plan. As of the Closing Date, Constar may establish a non-qualified supplemental executive retirement plan (“SERP”) covering such of its Active Constar Employees as it in its sole discretion deems appropriate. The SERP shall provide eligible employees with supplemental retirement benefits equal to the additional benefit that would be payable under the applicable Constar Pension Plan if not for the limitations imposed by sections 401(a)(17) and 415 of the Code or any successor provisions. ARTICLE VI EQUITY-BASED PLANS Section 6.1 Stock Option Awards. After the Closing Date, each unexercised stock option for Crown Common Stock held by an Active Constar Employee shall continue to be held as a option for Crown Common Stock and issuable under the applicable Crown Equity Plan. For such period as Crown owns a 25 percent or greater interest in Constar, employment by the Constar Group of Active Constar Employees holding options for Crown Common Stock shall be treated as employment by the Crown Group for purposes of the applicable Crown Equity Plans. At such time as Crown’s ownership interest in Constar falls below 25 percent or such earlier time as Constar is no longer deemed an “affiliate” under the applicable Crown Equity Plans, employment by the Constar Group shall no longer be treated as employment by the Crown Group for purposes of the Crown Equity Plans. Consequently, the employment of each Active Constar Employee and by the Crown Group shall be considered terminated by Crown for purposes of the Crown Equity Plans and each unexercised stock option for Crown Common Stock held by an Active Constar Employee which previously became exercisable shall remain exercisable only in accordance with the applicable award agreement and any option which is not

yet exercisable shall terminate. With respect to any stock option for Crown Common Stock exercised by an Active Constar Employees or Former Constar Employee, Crown shall be entitled to any tax deduction and in its sole discretion shall determine the treatment related to any such tax deduction with respect to the exercise of such stock options. Section 6.2 Stock Purchase Plan. (a) Establishment of Stock Purchase Plan. Effective as of the Closing Date, Constar shall establish an employee stock purchase plan (the “Constar ESPP”) that will provide benefits for a period of one year after the Closing Date that are at least substantially equivalent in all Material Features to those provided under the Crown Employee Stock Purchase Plan (the “Crown ESPP”) immediately before the Closing Date. (b) Asset Transfer. Prior to the Closing Date, all Active Constar Employees (and Former Constar Employees, if applicable) currently participating in the Crown ESPP shall be given an election to have the total amount of cash credited to their account under the Crown ESPP as of the Closing Date returned to them in a cash lump sum payment (without interest) or to have such amount transferred to the Constar ESPP. ARTICLE VII FOREIGN PLANS AND TRANSITION EMPLOYEES Section 7.1 Foreign Retirement Plans. Crown and Constar shall use their reasonable best efforts so that, as soon as practicable after the Closing Date, all Crown Foreign Plans which provide retirement benefits solely to Active Constar Employees and Former Constar Employees shall be assumed by Constar together with all related assets and liabilities and neither the Crown Group nor any Crown Group Plan shall retain any liability with respect to such Foreign Plans. Section 7.2 Foreign Welfare Plans. Crown and Constar shall use their reasonable best efforts, effective as of the Closing Date, and to the extent allowed under foreign laws, to handle the Foreign Plans which provide welfare benefits in a manner which mirrors the approach outlined in this Agreement for the various employee benefit plans. Section 7.3 Transition Employees. Crown and Constar have agreed that the employees listed in Appendix C will be classified as “Transition Employees.” For the “Applicable Period” (as described below), these Transition Employees will continue to be employed by Crown but will provide services exclusively to Constar in accordance with the Research and Development Agreement. At the end of the Applicable Period, or earlier, if mutually agreed to by the Parties, the Transition Employees shall be terminated by Crown and shall be offered employment with Constar. The “Applicable Period” with respect to Transition Employees who, as of the Closing Date, are in the process of seeking permanent residency in the United States, shall be the later of (i) six months from the Closing Date, and (ii) the period from the Closing Date until the date permanent residency is granted. The “Applicable Period” with respect to Transition Employees who, as of the Closing Date, are not in the process of seeking permanent residency shall be six months from the Closing Date. At such time as the Transition Employees become employed by Constar (the “Transition Date”), the Transition Employees

shall be considered Active Constar Employees and will subject to all of the terms of this Agreement as of the Transition Date. ARTICLE VIII GENERAL Section 8.1 Payment of and Accounting Treatment for Expenses and Balance Sheet Amounts. (a) Expenses. Except as specifically provided in this Agreement, all expenses (and the accounting treatment related to such expenses) related to liabilities through the Closing Date regarding matters addressed in this Agreement shall be handled and administered in the ordinary course by Crown and Constar in accordance with past Crown accounting and financial practices and procedures pertaining to such matters. To the extent such expenses are unpaid as of the Closing Date that pertain to Active Constar Employees or Former Constar Employees, Constar shall be solely responsible for such payment, without regard to any accounting treatment to be accorded such expense by Crown or Constar on their respective books and records. The accounting treatment to be accorded all such expenses, whether such expenses are paid by Crown or Constar, shall be determined by Crown. (b) Balance Sheet Amounts. Constar shall assume any balance sheet liability for any Liabilities assumed by it under this Agreement as of the Closing Date or thereafter, with respect to any Active Constar Employee or Former Constar Employees. The determination of any balance sheet liability as of the Close of the Closing Date shall be determined by Crown consistent with past accounting practices, consistently applied. Section 8.2 Accounting Adjustments. Before the Closing Date, Constar will have established on its books for financial accounting purposes liabilities and reserves for deferred compensation, welfare and other employee benefit plan obligations that will be retained or assumed by Constar under this Agreement, and Crown will have adjusted the liabilities and reserves on its books for financial accounting purposes to take into account Constar’s assumption or retention of Liabilities under this Agreement. The initial adjustments as of the Closing Date, will be made on an estimated basis. After the Parties have finally calculated the actual liabilities under this Agreement, each Party shall appropriately adjust its liabilities and reserves to reflect the amount of the liabilities and reserves that are properly allocable to that Party. Except as otherwise provided in Article III and Article VI, neither Party shall have any obligation to make payments or transfer assets to the other Party with respect to such adjustments.

No waiver of any term, provision or condition of or failure to exercise or delay in exercising any rights or remedies under this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, provision, condition, right or remedy or as a waiver of any other term, provision or condition of this Agreement. Section 8.5 Sharing of Participant Information. Crown and Constar shall share, Crown shall cause each applicable member of the Crown Group to share, and Constar shall cause each applicable member of the Constar Group to share, with each other and their respective agents and vendors (without obtaining releases) all participant information necessary for the efficient and accurate administration of each of the Crown Plans and the Constar Plans.

binding upon, and shall inure to the benefit of, the Parties and their respective successors and permitted assigns. Section 8.8 No Third-Party Beneficiaries; No Termination of Employment. No provision of this Agreement shall be construed to create any right, or accelerate entitlement, to any compensation or benefit whatsoever on the part of any Active Constar Employee or Former Constar Employee under any Crown Plan or Constar Plan or otherwise. Without limiting the generality of the foregoing, neither the Offering nor the termination of the controlled group status of a member of the Constar Group shall cause any employee to be deemed to have incurred a termination of employment that by itself entitles such individual to the commencement of benefits under any of the Crown Plans, any of the Constar Plans, or any individual agreements. Section 8.9 Right to Amend or Terminate Any Plans. Nothing in this Agreement other than those provisions specifically set forth in this Agreement to the contrary shall preclude Constar or Crown, at any time after the Closing Date, from amending, merging, modifying, terminating, eliminating, reducing, or otherwise altering in any respect any Constar Plan or Crown Plan, respectively, any benefit under any Plan or any trust, insurance policy or funding vehicle related to any Constar Plan or Crown Plan. Section 8.10 Effect if Offering Does Not Occur. If the Offering does not occur, then all actions and events that are, under this Agreement, to be taken or occur effective as of the Closing Date, immediately after the Closing Date, or otherwise in connection with the Offering, shall not be taken or occur except to the extent specifically agreed to in writing by Constar and Crown. Section 8.11 Relationship of Parties. Nothing in this Agreement shall be deemed or construed by the Parties or any third party as creating the relationship of principal and agent, or a partnership or joint venture between the Parties, it being understood and agreed that no provision contained in this Agreement, and no act of the Parties, shall be deemed to create any relationship between the Parties other than the relationship set forth in this Agreement. Section 8.12 Affiliates.

The auditing Party shall have the right to make copies of any records at its expense. The Party being audited shall provide the

(ii) The auditing Party’s audit rights under this Section shall include the right to audit, or participate in an audit facilitated by the Party being audited, of any Subsidiaries and affiliates of the Party being audited and of any benefit providers and third parties with whom the Party being audited has a relationship, or agents of such Party, to the extent any such persons are affected by or addressed in this Agreement. The Party being audited shall, upon written request from the auditing Party, provide an individual (at the auditing Party’s expense) to supervise any audit of any such benefit provider or third-party.

Section 8.15 Severability. The provisions of this Agreement are severable and should any provision of this Agreement be void, voidable or unenforceable under any applicable law, such provision shall not affect or invalidate any other provision of this Agreement, which shall continue to govern the relative rights and duties of the Parties as though such void, voidable or unenforceable provision were not part of this Agreement.

(a) Resolution of any and all disputes arising from or in connection with this Agreement, whether based on contract, tort, statute or otherwise, including, but not limited to, disputes in connection with claims by third parties (collectively, “Disputes”), shall be subject to the provisions of this Section 8.18; provided, however, that nothing contained in this Agreement shall preclude either Party from seeking or obtaining (i) injunctive relief or (ii) equitable or other judicial relief to enforce the provisions of this Agreement or to preserve the status quo pending resolution of Disputes hereunder. (b) Either Party may give the other Party written notice of any Dispute not resolved in the normal course of business. The parties shall attempt in good faith to resolve any Dispute promptly by negotiation between executives of the parties who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement. Within 30 days after delivery of the notice, the foregoing executives of both parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary for a period not to exceed 15 business days, to attempt to resolve the Dispute. All reasonable requests for information made by one Party to the other will be honored. If the parties do not resolve the Dispute within such 45 business day period (the “Initial Negotiation Period”), the Parties shall attempt in good faith to resolve the Dispute by negotiation between (a) in the case of Crown, the Chief Financial Officer and (b) in the case of Constar, the Chief Financial Officer (collectively, “Designated Officers”). Such officers shall meet at a mutually acceptable time and place (but in any event no later than 15 business days following the expiration of the Initial Negotiation Period) and thereafter as often as they reasonably deem necessary for a period not to exceed 15 business days, to attempt to resolve the Dispute. (c) If the Dispute has not been resolved by negotiation within 75 business days of the first Party’s notice, or if the Parties failed to meet within 30 business days of the first Party’s notice, or if the Designated Officers failed to meet within 60 business days of the first Party’s notice, either Party may commence any litigation or other procedure allowed by law.
