After delivery of the Earnout Statement, the Seller Representative and its representatives shall be permitted reasonable access during normal business hours to

4

review the Purchaser’s and the Georgia Business’s contracts and books and records and any work papers (including any work papers of the Purchaser’s and the Georgia Business’s accountants) related to the preparation of the Earnout Statement. The Seller Representative and its representatives shall be entitled to make reasonable inquiries of Purchaser and, subject to Purchaser’s prior approval (which approval shall not be unreasonably withheld, conditioned or delayed), its senior level or other highly knowledgeable employees, accountants and other representatives regarding questions concerning or disagreements with the Earnout Statement arising in the course of their review thereof, and the Purchaser shall use its commercially reasonable efforts to cooperate, and to cause its senior level or other highly knowledgeable employees, accountants and other representatives to cooperate, with and promptly respond to such inquiries.

Section 2.2 Earnout Statement Dispute Resolution.

(a) If the Seller Representative has any objections to the Earnout Statement, the Seller Representative shall deliver to the Purchaser a statement setting forth in reasonable detail each item in dispute, the amount thereof in dispute and the basis for its objections thereto (an “Objections Statement”). If (i) the Seller Representative notifies the Purchaser in writing of its acceptance of the Earnout Statement or (ii) an Objections Statement is not delivered to Purchaser within sixty (60) days after delivery of the Earnout Statement, then the Earnout Statement shall be final, binding and nonappealable and the Purchaser shall, within five (5) Business Days thereafter, pay the Earnout Amount (if any) by wire transfer of immediately available funds to one or more bank accounts designated in writing by the Seller Representative. The Purchaser and the Seller Representative shall negotiate in good faith to resolve any objections set forth in the Objections Statement (and all such discussions related thereto shall, unless otherwise agreed by the Purchaser and the Seller Representative, be governed by Rule 408 of the Federal Rules of Evidence (and any applicable similar state rule)), but if they do not reach a final resolution within thirty (30) days after the delivery of the Objections Statement, either Purchaser or Seller may elect to submit such dispute to the Arbitrator. The Purchaser shall pay the portion of the Earnout Amount (if any) that is not in dispute by wire transfer of immediately available funds to one or more bank accounts designated in writing by the Seller Representative within five (5) Business Days after delivery of the Objections Statement.

(b) If any dispute is submitted to the Arbitrator, each of the Purchaser and the Seller Representative will furnish to the Arbitrator such work papers and other documents and information relating to the disputed issues as the Arbitrator may request and are

5

reasonably available to such party or its accountants and shall otherwise cooperate and comply with the Arbitration Rules (unless the Purchaser and the Seller Representative agree in writing that other arbitration rules or procedures shall apply) and each of the Purchaser and the Seller Representative shall be entitled to present to the Arbitrator material relating to the determination and to discuss, in the presence of the other, the determination with the Arbitrator. The Arbitrator shall resolve only those matters that remain in dispute after the thirty (30)-day resolution period. The Purchaser and the Seller Representative shall instruct the Arbitrator to resolve all such disagreements as soon as practicable but in no event later than seventy-five (75) days after submission of the disputed issues to the Arbitrator. The resolution of the dispute by the Arbitrator shall be final, binding and nonappealable. The Earnout Statement shall be modified to the extent necessary to reflect such determination.

(c) The fees and expenses of the Arbitrator shall be borne 50% by the Purchaser, on the one hand, and 50% by the Seller Representative on behalf of the Seller, on the other hand.

Section 2.3 Payment of Earnout Amounts. With respect to each Earnout Measurement Period, the Purchaser shall pay the Earnout Amount (if any) by wire transfer of immediately available funds to one or more bank accounts designated in writing by the Seller Representative within five (5) Business Days following the date that the Earnout Amount for such Earnout Measurement Period becomes final and binding in accordance with Section 2.2 (Earnout Statement Dispute Resolution), together with interest on any portion of the Earnout Amount that was not reflected in Purchaser’s Earnout Statement but was agreed by the parties or finally determined by the Arbitrator. Such interest shall accrue from the date that is five (5) Business Days after delivery of the Objections Statement until the date of payment, at a rate equal to the prime rate of Citibank, N.A. in effect on the accrual commencement date.

Section 2.4 Operation and Management of the Georgia Business.

(a) Except as the Purchaser and the Seller Representative may otherwise agree in writing or to the extent otherwise provided in this Agreement, the Purchaser shall, and shall cause its Subsidiaries and their respective officers, managers and employees to, use commercially reasonable efforts to (x) operate the Georgia Business at all times during the Earnout Period in good faith and in an economically rational manner consistent with reasonable business practices (including with respect to capital expenditures), and (y) conduct substantially all business and operations of Purchaser and its Subsidiaries primarily relating to the manufacturing, sale and distribution of conventional and isothermal forged disks that are within the capabilities of the Georgia Facility at and through the Georgia Facility; provided that the foregoing shall not prohibit the Purchaser and its Subsidiaries and the Companies and their Subsidiaries from continuing to operate their current businesses, including all currently existing product lines, as conducted on the date hereof. In no event shall the Purchaser, and the Purchaser shall cause its Subsidiaries and their respective officers, managers and employees not to, take, or fail to take, any actions with the primary intention of reducing the amount of Georgia EBITDA during the Earnout Period or otherwise circumventing the earnout contemplated by this Agreement. Without limiting the foregoing, during the Earnout Period, except as the Purchaser and the Seller Representative may otherwise agree in writing, the Purchaser shall not, and the Purchaser shall cause its Subsidiaries and their respective officers, managers and employees not to:

(ii) sell, assign, transfer, convey, lease or otherwise dispose of any equity interests of the Georgia Business Subsidiary, including by stock sale, merger, consolidation, stock swap, business combination, sale of assets or similar transaction, except to or with Purchaser or a Subsidiary of Purchaser, unless appropriate adjustments are made to the earnout contemplated by this Agreement;

(iii) compete in any material respect with the Georgia Business as currently conducted or as currently planned to be conducted, whether as owner, partner, shareholder, or co-venturer, or otherwise, engage, participate or invest in any Person that competes with the Georgia Business as currently conducted or as currently planned to be conducted, in each case unless appropriate adjustments are made to the earnout contemplated by this Agreement; provided, however, that no adjustment to the earnout contemplated by this Agreement shall be required (A) for any investment in publicly traded stock of a company representing less than 5% of the capital stock of such company or (B) in respect of the continued operation of the current businesses of the Companies and their Subsidiaries as conducted on the date hereof;

(iv) provide bundled pricing or similar discounts or incentives to customers that disadvantage the Georgia Business versus Purchaser’s other businesses;

In the event that appropriate adjustments are required to be made to the earnout pursuant to the foregoing provisions, the Purchaser and the Seller Representative shall cooperate in good faith to agree on adjustments with the objective of providing to the Seller Representative the same economic effect as contemplated by this Agreement prior to such event.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the extent possible.

Except as otherwise explicitly provided for elsewhere herein, all rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.
