person. The person also must agree to notify Supplier of any instances of which it is aware in which the confidentiality of the information has been breached.

Spinco shall assume all Liabilities for or related to Active Spinco Employees (and Former Spinco Employees, if applicable) payable under any bonus plan sponsored or maintained by Spinco or Supplier with respect to the period prior to the Distribution Date; provided, however, that Supplier and Spinco may jointly make such adjustments to the financial goals, targets, payments and forms of payment as they deem appropriate to reflect the Distribution. As of the Distribution Date, Spinco may establish a bonus plan covering such of its Active Spinco Employees as it in its sole discretion deems appropriate.

ARTICLE VI
STOCK INCENTIVE PLANS

6.1 Stock Option Awards.

(a) Effective as of the Distribution Date, Spinco shall establish an equity-based incentive plan for the benefit of Spinco's employees, consultants and directors ("Spinco Stock Incentive Plan"), with such terms as Spinco determines, in its sole discretion.

(b) Except as provided in Section 6.1(c) for Key Recipients and Section 6.1(d) for Director Recipients, employees and consultants who have received unexercised options (whether vested or unvested) to purchase Supplier Common Stock ("Supplier Options") under the Supplier Stock Incentive Plans before the Distribution Date, and who become employees or consultants of Spinco on the Distribution Date, will have each of their unexercised Supplier Options converted into options to purchase Spinco Common Stock ("Spinco Options") under the Spinco Stock Incentive Plan as of the Distribution Date, subject to the following terms and conditions:

(i) The terms of the conversion described in this Section will be determined by reference to, and in consideration of, the ratio of the market price of Supplier common stock and Spinco Common Stock immediately before or after the distribution. The conversion will

preserve the then intrinsic value of the existing Supplier Options. Following the conversion contemplated by this Section, the aggregate market value of the Spinco Common Stock purchasable under the Spinco Options immediately after the Distribution will be approximately equal to the aggregate market value of the Supplier Common Stock that was purchasable under the Supplier Options immediately before the distribution, with the aggregate exercise price of the Spinco Options being the same as the Supplier Options (except to the extent the number of shares purchasable is rounded down to the nearest whole share).

(ii) The term, vesting and other terms of the Spinco Options will be the same as the terms of the current Supplier Options; notwithstanding any contrary provision of the Spinco Stock Incentive Plan.

(c) Each Key Recipient of Supplier Options under the Supplier Stock Incentive Plans before the Distribution Date who becomes an employee or consultant of Spinco on the Distribution Date, will, have 30% of his or her unexercised vested Supplier Options converted into Spinco Options under the Spinco Stock Incentive Plan as of the Distribution Date. The remaining 70% of his or her vested, unexercised Supplier Options shall remain under the terms of the Supplier Stock Incentive Plan ("Key Supplier Options"). Unvested Supplier Options held by Key Recipients (other than the Designated Key Recipient identified on Schedule I) will be converted into Spinco Options in accordance with Section 6.1(b). Unvested Supplier Options held by the Designated Key Recipient identified on Schedule I will remain under the terms of the Supplier Stock Incentive Plan as unvested Key Supplier Options. Supplier will administer the applicable Supplier Stock Incentive Plan to provide that the holders of the Key Supplier Options will not be treated as terminating employment or service with Supplier due to the Distribution, solely for purposes of determining the terms applicable to the Key Supplier Options after the Distribution Date. The term, vesting and other terms of the Spinco Options will be the same as the terms of the current Supplier Options. The valuation and determination of the number of Spinco Options and Supplier Options will be made in the same manner as described in Section 6.1(b)(i).

(d) Each recipient of Supplier Options who is a director of Supplier ("Director Recipient") before the Distribution Date will have 30% of his or her unexercised Supplier Options converted into Spinco Options under the Spinco Stock Incentive Plan as of the Distribution Date. The remaining 70% of his or her unexercised Supplier Options shall remain under the terms of the Supplier Stock Incentive Plan ("Director Supplier Options"). Supplier will administer the applicable Supplier Stock Plan to provide that the holders of the Director Supplier Options who do not remain as directors of Supplier after the Distribution will not be treated as terminating service from Supplier due to the Distribution, solely for purposes of determining the terms applicable to the Director Supplier Options after the Distribution Date. The term, vesting and other terms of the Spinco Options will be the same as the terms of the current Supplier Options. The valuation and determination of the number of Spinco Options and Supplier Options will be made in the same manner as described in Section 6.1(b)(i).

(e) Spinco shall make such additional awards under the Spinco Stock Incentive Plan to Active Spinco Employees, consultants and directors as it in its sole discretion deems appropriate.

6.2 Employee Stock Purchase Plan.

(a) Effective as of the Distribution Date, Spinco shall establish an employee stock purchase plan (the "Spinco ESPP") that will provide benefits that are similar to those provided under the Supplier Employee Stock Purchase Plan (the "Supplier ESPP") immediately before the Distribution Date.

(b) Effective as of the Distribution Date, Supplier shall amend the Supplier ESPP to provide that any amounts contributed by Active Spinco Employees to the Supplier ESPP shall be

transferred to Spinco and shall be applied to the purchase of Spinco Common Stock under the Spinco ESPP. The rights to purchase Supplier Common Stock, which have been earned under the Supplier ESPP shall be converted, in accordance with the procedures described in Section 6.1(b) and applicable law, into rights to purchase Spinco Common Stock under the Spinco ESPP effective as of the Closing Date. The initial "purchase period" under the Spinco ESPP will end on the same date that such period is scheduled to end under the Supplier ESPP. Additional purchase periods under the Spinco ESPP will be subject to the terms and conditions determined by Spinco in its sole discretion.

ARTICLE VII
FOREIGN PLANS

7.1 Foreign Retirement Plans. Supplier and Spinco shall use their reasonable best efforts so that, as soon as practicable after the Distribution Date, all Supplier Foreign Plans which provide retirement benefits solely to Active Spinco Employees and Former Spinco Employees shall be assumed by Spinco together with all related assets and liabilities and neither Supplier nor any Supplier Group Plan shall retain any liability with respect to such Foreign Plans.

7.2 Foreign Welfare Plans. Supplier and Spinco shall use their reasonable best efforts, effective as of the Distribution 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.

ARTICLE VIII
ACCOUNTING

8.1 Payment of and Accounting Treatment for Expenses.

(a) Except as specifically provided in this Agreement, all expenses (and the accounting treatment related to such expenses) related to liabilities through the Distribution Date regarding matters addressed in this Agreement shall be handled and administered in the ordinary course by Supplier and Spinco in accordance with past Supplier accounting and financial practices and procedures pertaining to such matters. To the extent such expenses are unpaid as of the Distribution Date that pertain to Active Spinco Employees or Former Spinco Employees, Spinco shall be solely responsible for such payment, without regard to any accounting treatment to be accorded such expense by Supplier or Spinco on their respective books and records. The accounting treatment to be accorded all such expenses, whether such expenses are paid by Supplier or Spinco, shall be determined by Supplier.

(b) Spinco shall assume any balance sheet liability for any Liabilities assumed by it under this Agreement as of the Distribution Date or thereafter, with respect to any Active Spinco Employee or Former Spinco Employees. The determination of any balance sheet liability as of the close of business on the Distribution Date shall be determined by Supplier consistent with past accounting practices, consistently applied.

8.2 Accounting Adjustments. Before the Distribution Date, Spinco 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 Spinco under this Agreement, and Supplier will have adjusted the liabilities and reserves on its books for financial accounting purposes to take into account Spinco's assumption or retention of Liabilities under this Agreement. The initial adjustments as of the Distribution 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.

ARTICLE IX

10.6 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 Spinco or Supplier, at any time after the Distribution Date, from amending, merging, modifying, terminating, eliminating, reducing, or otherwise altering in any respect any Spinco plan or Supplier Plan, respectively, any benefit under any Plan or any trust, insurance policy or funding vehicle related to any Spinco Plan or Supplier Plan.

10.11 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.

(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 Supplier, the Chief Financial Officer and (b) in the case of Spinco, 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.

This Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respective successors and permitted assigns. Notwithstanding the foregoing, Spinco may, and hereby gives notice to Supplier that it intends to, pledge its rights and obligations under this Agreement to its lenders as collateral to secure indebtedness outstanding under its senior secured credit facility and all renewals, refundings, refinancings and replacements thereof.

10.16 Interpretation. Words in the singular shall be held to include the plural and vice versa and words of one gender shall be held to include the other genders as the context requires.
