Purchaser shall pay $142,500,000 of the Purchase Price, as adjusted pursuant to Section 3.1(d), at Closing as set forth in Section 3.1(b), and shall pay the remaining $4,500,000 of the Purchase Price (the “Hold-back Amount”) in accordance with Section 3.1(g).

(d)   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 (i) Working Capital, and the components and calculation thereof in reasonable detail, as of the close of business of the Automotive Business on the Closing Date (the “Estimated Closing Working Capital”), and (ii) the Indebtedness of any Acquired Subsidiaries or that is included in the Assumed Liabilities (the “Assumed Indebtedness”).  Such statement shall be accompanied by a certificate of the chief financial officer of Seller stating that such statement represents Seller’s good faith estimate as of such date of (A) Working Capital of the Automotive Business on the Closing Date determined in accordance with GAAP applied on a basis consistent with the May Balance Sheet, and (B) the Assumed Indebtedness as of the Closing Date.  To the extent that the Estimated Closing Working Capital as shown on the Estimated Statement exceeds the Target Working Capital (such excess, the “Interim Upward Adjustment”), then the Purchase Price will be increased dollar-for-dollar by the amount of the Interim Upward Adjustment, and to the extent that Estimated Closing Working Capital as shown on the Estimated Statement is less than Target Working Capital (such shortfall, the “Interim Downward Adjustment”), then the Purchase Price will be decreased dollar-for-dollar by the amount of the Interim Downward Adjustment.  In addition, the Purchase Price will be reduced dollar-for-dollar by an amount equal to the sum of (i) the estimated Assumed Indebtedness and (ii) the difference between the Target Unbilled Reimbursable Tooling Expenditures and the Agreed Upon Unbilled Reimbursable Tooling Inventory.

(f)    Seller will have 60 days to review the Adjustment Statement, after which period, if Seller has not disputed in writing (an “Objection”) the Adjustment Statement, Seller will be deemed to have accepted and agreed with the Adjustment Statement.  Purchaser shall provide Seller with access to purchase orders and other materials to enable Seller to review the Adjustment Statement in a timely fashion.  An Objection shall set forth a specific description of the basis of the Objection and the adjustments to the amount of Closing Working Capital, Assumed Indebtedness, Closing Third Quarter Capital Expenditures and Closing Third Quarter Tooling Expenditures which Seller believes should be made, which Objection must be delivered to Purchaser on or before the last day of such 60-day period.  Purchaser shall have 30 days to review and respond to the Objection.

(iii)          in the event that an amount of Assumed Indebtedness as of the Closing Date exceeds the Assumed Indebtedness estimated by Seller pursuant to Section 3.1(d), the Purchase Price shall be decreased by the amount of such difference;

7

(iv)          in the event that the amount of Assumed Indebtedness is less than the Assumed Indebtedness estimated by Seller pursuant to Section 3.1(d), the Purchase Price shall be increased by the amount of such difference;

(v)           in the event that the amount of the Closing Third Quarter Capital Expenditures exceeds the Target Capital Expenditure Amount, the Purchase Price shall be increased by the amount of such excess;  and

(vi)          in the event that the amount of the Closing Third Quarter Capital Expenditures is less than the Target Capital Expenditure Amount, the Purchase Price shall be decreased by the amount of such difference.

(vii)         in the event that the amount of the Closing Third Quarter Tooling Expenditures exceeds the Target Tooling Expenditure Amount, the Purchase Price shall be increased by the amount of such excess; and

(viii)        in the event that the amount of the Closing Third Quarter Tooling Expenditures is less than the Target Tooling Expenditure Amount , the Purchase Price shall be decreased by the amount of such difference.

The net of the adjustments described in clauses (i) through (viii) above is the “Final Purchase Price Adjustment Amount.”  To the extent that the Final Purchase Price Adjustment Amount represents an increase in the Purchase Price, Purchaser shall promptly make payment in immediately available funds to Seller of the sum of the Final Purchase Price Adjustment Amount and the Hold-back Amount.  To the extent that the Final Purchase Price Adjustment Amount represents a decrease in the Purchase Price, (i) if the Final Purchase Price Adjustment Amount is greater than the Hold-back Amount, Seller shall promptly make payment in immediately available funds to Purchaser of the positive difference between the Final Purchase Price Adjustment Amount and the Hold-back Amount, and (ii) if the Final Purchase Price Adjustment Amount is less than the Hold-back Amount, Purchaser shall promptly make payment in immediately available funds to Seller of the positive difference between the Hold-back Amount and the Final Purchase Price Adjustment Amount.  Any payment made in accordance with this paragraph shall be made together with interest on such Final Purchase Price Adjustment Amount from the Closing Date to the date of payment at a per annum rate equal to the JP Morgan Chase prime rate.  Notwithstanding anything to the contrary contained herein, no payment of the Hold-back Amount shall be due from Purchaser to Seller under this Section 3.1(g) until the complete registration by the Companies Register (Registro Mercantil) of Barcelona of the New Iberica Shares as contemplated in Section 9.8.

(h)   The Parties shall attempt in good faith to reach an agreement with respect to any matters in dispute.  If the parties are unable to reach agreement with respect to the Adjustment Statement within 30 days following the delivery of Purchaser’s response to an Objection, the matter shall be resolved by an accounting firm mutually acceptable to both parties or, in the absence of agreement, by an accounting firm of national reputation selected by lot after eliminating Seller’s and Purchaser’s principal outside accountants.  The selected accounting firm shall be directed by the Parties to use its best efforts to render its determination within 30-days after such submission.  The

8

determination by the accounting firm so selected of the Adjustment 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 in acting under this Section 3.1 shall be shared equally by Purchaser and Seller.

(i)    Purchaser will give Seller and its representatives reasonable access to the premises of the Automotive Business and Acquired Subsidiaries, to their respective books and records and to the appropriate personnel of Purchaser, the Automotive Business and the Acquired Subsidiaries for purposes of confirming the Adjustment Statement.

(j)    Allocation of Purchase Price.  The Parties (A) shall be bound by the Final Allocation for purposes of determining any and all consequences with respect to Taxes of the Transaction contemplated herein, (B) shall prepare and file all Tax Returns and reports to be filed with any Governmental Authority, including Internal Revenue Service Form 8594, if necessary, in a manner consistent with the Final Allocation and (C) shall take no position inconsistent with the Final Allocation on any Tax Return, any discussion with or proceeding before any Governmental Authority or otherwise.
