          (d) Neither the Sellers nor, prior to the Closing, any of the Acquired Companies shall, without the prior written consent of Alon, terminate, amend, modify or waive any provision of any confidentiality or similar agreement pertaining to proprietary or confidential documents or information of or concerning the Acquired Companies or their respective businesses to which any of the Sellers or any Acquired Company is a party. Each of the Sellers and, prior to the Closing, the Acquired Companies shall enforce, to the fullest extent permitted under applicable law, the provisions of any such agreements, including using commercially reasonable efforts to obtain injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court having jurisdiction over the matter.

respective legal obligations (including requirements of stock exchanges and similar Governmental Entities), consult with each other, and use reasonable efforts to agree upon the text of any press release or other public communication, before issuing any such press release or public communication with respect to the transactions contemplated hereby and in making any filings with any Governmental Entity or with any national securities exchange with respect thereto.

     6.5 Expenses; Law Firms.

          (a) Except as set forth herein, all costs and expenses (including fees of attorneys, accountants and brokers or finders) incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses; provided however, Alon, on the one hand, and the Sellers, on the other hand, shall each be responsible for one half of (i) all filing fees in connection with the filings required by the HSR Act, (ii) all fees of the entity providing the inventory measurement as set forth in Schedule 2.4(b), and (iii) the premium for the Tail Policy.

          (b) Alon acknowledges that the law firms representing the Sellers and the Company in connection with the Stock Purchase listed on Schedule 6.5 have long-standing relationships with the Sellers, and notwithstanding any payment by the Company of any legal fees of the Sellers or the Acquired Companies pursuant to Section 6.5(a), in the event of any dispute or potential dispute between the parties hereto, the Sellers may desire to engage one or more of such law firms to advise the Sellers in connection with such dispute or potential dispute or any other matter. Accordingly, Alon hereby agrees that it shall not, and shall not permit any of the Acquired Companies to, assert any claim that such representation of the Sellers by such law firms in any such matter creates an impermissible conflict of interest with the interests of the Acquired Companies (or any one of them) under the applicable rules of professional conduct. If the Closing occurs, to the extent of any such potential conflict of interest, Alon hereby waives, on behalf of itself, and the Acquired Companies, any such conflict, and with a full understanding of the implications of such potential conflicts of interest, provides its informed consent to the representation of the Sellers by any or all of such law firms in any such matters that may be adverse to Alon or the Acquired Companies.

     6.6 Employee Matters.

          (a) Until December 31, 2007, Alon shall cause the Acquired Companies to provide the continuing employees of the Acquired Companies employee benefits that are substantially equivalent to those provided to such employees as of the Closing Date by the Acquired Companies. Such benefits shall be provided though Company Benefit Plans, Alon

45

benefit plans or policies, or a combination of the foregoing, as determined by Alon in its discretion. Following the Closing, Alon shall recognize the years of service of each continuing employee of the Acquired Companies with the Acquired Companies prior to the Closing Date for all purposes (other than benefit accrual under a defined benefit pension plan) under the employee benefit plans and policies of Alon; provided, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits for the same period of service or to the extent that such service was not recognized under the corresponding Company Benefit Plan. To the extent that the continuing employees of the Acquired Companies become covered by any Alon group health plan, Alon shall cause any and all pre-existing condition (or actively at work or similar) limitations, eligibility waiting periods and evidence of insurability requirements under such plans to be waived with respect to such continuing employees of the Acquired Companies and their eligible dependents, to the extent satisfied under a corresponding Company Benefit Plan, and shall provide them with credit for any co-payments, deductibles, and offsets (or similar payments) made during the plan year including the date such employees become eligible to participate in such Alon group health plan for the purposes of satisfying any applicable deductible, out-of-pocket, or similar requirements under any such plan. For purposes of this Section 6.6, “continuing employee of the Acquired Companies” means an employee of the Acquired Companies as of the Closing Date.

          (b) Nothing contained in this Section 6.6 shall confer upon any employee of the Acquired Companies any right to continued employment or participation in any Company Benefit Plan at any time after the Closing Date.

          (c) If within one year after the Closing Date, the employment of any continuing employee of the Acquired Companies is terminated by the Acquired Company employer of such continuing employee (excluding any termination which is concurrent with the hiring of such continuing employee by another Acquired Company or an Affiliate of such Acquired Company), for other than cause (as defined under applicable law), the Acquired Companies shall pay such employee a lump sum, promptly after such termination, equal to the product of (i) two weeks of such employee’s base salary immediately prior to such termination (excluding any overtime or bonus payments) and (ii) the number of years of continuous service of such continuing employee with the Acquired Companies. The foregoing payments shall not apply to any continuing employee of the Acquired Companies who is party to a Contract with one of the Acquired Companies that provides for severance benefits upon termination of the employment of such employee or any continuing employee subject to a collective bargaining agreement or other labor contract.

          (d) Alon shall be solely responsible for any required notice and payments under the Worker Adjustment Retraining and Notification Act of 1988 (the “WARN Act”) and any similar state statutes, and otherwise to comply with any such statute with respect to any “plant closing” or “mass layoff” (as defined in the WARN Act) or group termination or similar event affecting any continuing employees of the Acquired Companies occurring on or after the Closing Date. The Sellers shall be solely responsible for causing the Acquired Companies to provide any required notice and payments under the WARN Act, and any similar state statutes, and otherwise to comply with any such statute with respect to any “plant closing” or “mass layoff” (as defined in the WARN Act) or group termination or similar event affecting any employees of the Acquired Companies before the Closing Date.

          (e) Prior to the Closing, the Sellers shall take all actions necessary to terminate the participation in the Company Benefit Plans, effective as of the Closing Date, of each Person that is not an Acquired Company, including, without limitation, Signal Hill Petroleum Inc.

The Sellers shall promptly communicate to Alon the existence or occurrence and the terms of any potential Third Party Acquisition or contact related to any potential Third Party Acquisition that the Sellers, their Affiliates (including the Acquired Companies) or any of their respective officers, directors, trustees, employees, representatives or agents, receive in respect of such a proposed transaction, and the identity of the Person from whom such proposal or contact was received.

          Notwithstanding the foregoing, nothing herein shall prohibit general solicitations by the Sellers or their Affiliates not directed at any specific employees of the Acquired Companies, including any newspaper advertisements or internet job postings.

          (b) The Sellers acknowledge that if they violate any of the covenants contained in Section 6.8(a) (collectively, the “Restrictive Covenants”), it will be difficult to determine the resulting damages to Alon and, in addition to any other remedies Alon may have, Alon shall be entitled to temporary or permanent injunctive relief without the necessity of proving actual damages. Each Seller shall be solely liable for a breach by such Seller of the covenants contained in this Section 6.8, and such liability shall not be joint.

          (iv) consenting or agreeing to, negotiating, entering into settlements and compromises of, and prosecuting and defending litigation, arbitration or other proceedings with respect to, such claims;

          (v) asserting, negotiating, entering into settlements and compromises of, and prosecuting and defending litigation, arbitration or other proceedings with respect to, any other claim by any Alon Indemnified Party against the Sellers for which they are jointly liable, in each case relating to this Agreement, the Holdback Escrow Agreement or the transactions contemplated hereby or thereby; and

          (vi) taking all actions necessary or appropriate in the judgment of the Sellers’ Representative for the accomplishment of the foregoing.

          No Seller will have any right to receive any such notice or communication or take any of the foregoing actions individually.

          (b) Within 10 Business Days after the date hereof the Sellers shall appoint the initial Sellers’ Representative, and notify Alon in writing as to the identity of such person. The Sellers (or their successors), may elect replacements to the Sellers’ Representative by the affirmative vote of at least three of the four Sellers, provided that Alon is notified in writing thereof (including written agreement by such replacement to serve as the Sellers’ Representative as set forth herein). Each of the Sellers acknowledge that actions taken, consents given and representations made by the Sellers’ Representative on behalf of the Sellers pursuant hereto shall be binding upon the Sellers. This appointment and grant of power and authority by each Seller is coupled with an interest and is irrevocable and shall not be terminated by any act of the Seller or by operation of law, whether by the death or incapacity of the Seller or by the occurrence of any other event. The Sellers’ Representative is authorized by the Sellers to take any action on behalf of the Sellers to facilitate or administer the transactions contemplated hereby, including without limitation, amending this Agreement, and executing such other documents or instruments as the Sellers’ Representative deems necessary or appropriate.

     6.13 Release. In consideration of the payments of the Purchase Price by Alon to the Sellers, but subject to Section 6.9, each Seller hereby gives the following general release effective as of the Closing Date.

          (a) Each Seller on behalf of himself or itself and his or its agents (including its trustees, if applicable), successors and assigns, hereby irrevocably and unconditionally releases, acquits and forever discharges each of Alon, the Acquired Companies, and their respective partners, stockholders, members, directors, officers and agents, and respective successors and assigns (collectively, the “Released Parties”), to the extent not prohibited by applicable law, from any and all charges, complaints, claims, obligations, promises, agreements, controversies, damages, causes of action, suits, demands, remedies, costs, losses, debts, expenses and fees, of every type, kind, nature, description or character, whether known or unknown, suspected or unsuspected, liquidated or unliquidated, including those arising out of or in connection with (i) the Seller’s employment with any of the Acquired Companies, if any, (ii) any equity or other interests the Seller may have or claim to have in the Acquired Companies, and (iii) the assets, properties, business, operations and Liabilities of the Excluded Company, whether before, on or after the Closing Date, or the existence of Hazardous Materials in or on soils, sediments, surface water or groundwater at, on, under or from such assets and properties, in each case arising from events, occurrences or circumstance prior to the Closing (the “Claims”). Each Seller represents that he or it has not heretofore assigned or transferred or purported to have assigned or transferred to any Person any Claims released, acquitted and forever discharged herein. This general release shall not affect any rights that the Sellers may have which arise solely under this Agreement, including payment of the Purchase Price, or that arise after the Closing Date.

          (b) Each Seller acknowledges and agrees that the releases made herein constitute final and complete releases of the Released Parties with respect to all Claims. Each Seller expressly acknowledges and agrees that this general release is intended to include in its effect, without limitation, all Claims which Seller does not know or suspect to exist in his or its favor at the time hereof, and this general release contemplates the extinguishment of any and all such Claims. In this regard, each Seller expressly waives the provisions of Section 1542 of the California Civil Code, which states:

          A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Furthermore, each Seller hereby expressly waives and relinquishes any rights and benefits he or it may have under other statutes or common law principles of similar effect. Each Seller understands that the facts under which he or it gives this full and complete release and discharge of the Released Parties may hereafter prove to be different than now known or believed by such Seller and such Seller hereby accepts and assumes the risk thereof and agrees that his or its full and complete release and discharge of the Released Parties shall remain effective in all respects and not be subject to termination, rescission or modification by reason of any such difference in facts.

     6.14 Distribution of Excluded Company. Subject to compliance of Alon with its obligations in Section 6.19, on or before the Closing Date, the Sellers shall cause all of the equity interests in the Excluded Company to be transferred to the Sellers in their Pro Rata Portion as a distribution in partial redemption of the stock of the Company.

     6.15 Subordinated Debt. On or before the Closing Date, the Sellers shall cause the Company to repay to the Sellers the principal amount of the Subordinated Debt. For the avoidance of doubt, the net effect of such repayment shall not result in any adjustment to the Purchase Price.

     6.16 Holdback Escrow Agreement. At or prior to the Closing, Alon and the Sellers shall, and shall use commercially reasonable efforts to cause the Escrow Agent to, execute the Holdback Escrow Agreement.

     6.17 Casualty; Condemnation. In the event that, after execution of this Agreement but prior to the Closing Date, any material asset of the Acquired Companies is subject to (a) loss, destruction or damage (a “Casualty”), or (b) condemnation or partial condemnation by a Governmental Entity (a “Condemnation”), all proceeds from any insurance claims, condemnation awards, compensation or other reimbursements relating to such Casualty or Condemnation (i) received by any Seller or any Affiliate of a Seller, whether before, on or after the Closing Date, shall be promptly paid over to the Company, or (ii) received by the Company whether before, on or after the Closing Date, shall be retained by the Company (and may, for the avoidance of doubt, at the Company’s sole option, be used to repair any such loss, destruction or damage). Any party receiving a notice of Casualty or Condemnation shall notify all other parties to this Agreement in accordance with Section 11.3.

     6.18 Title Commitments. Prior to the Closing, Alon may in its sole discretion obtain a title commitment (the “Title Commitment”) for one or more ALTA title insurance policies (the "Title Policies”) to be issued by a title company selected by Alon (the “Title Company”) and a survey (the “Survey”) with respect to each parcel of Owned Real Property and Leased Real Property. Each Title Commitment shall list as exceptions all matters that may affect title to such Owned Real Property, including, without limitation, all easements, covenants, restrictions, Liens, encumbrances, tenancies and other exceptions to title affecting title to the applicable parcel of Real Property (collectively, the “Exceptions”) and shall include copies of all instruments creating such Exceptions. Alon may following its review of any Title Commitment and no more than ten days after receipt of the Title Commitment, provide the Acquired Companies with written notice of objection to any Exceptions (other than the Permitted Liens, except Permitted Liens which are unrecorded Liens) that it claims constitutes a title or survey defect that first occurred during the period such Owned Real Property was owned by the Acquired Companies, or if a shorter period, during the period the applicable Acquired Company was owned, directly or indirectly, by the Sellers (the “Title Objections”). The Acquired Companies shall use commercially reasonable efforts to cure or remove such Title Objections to Alon’s reasonable satisfaction prior to Closing; provided however, so long as the Acquired Companies have used commercially reasonable efforts to cure or remove such Title Objections, the cure or removal of such Title Objections shall not be a condition of Alon to close the transactions contemplated hereby. Sellers and the Acquired Companies agree to reasonably cooperate with Alon in executing any documents reasonably requested by the Title Company which may be necessary to

issue the Title Policies, including providing any affidavit reasonably requested by the Title Company or Alon to evidence the payment or satisfaction of any Liens, to evidence the payment of any Taxes affecting the Owned Real Property, or to evidence the satisfaction of any other matter which Alon may be required to establish in order to obtain the Title Policies or any endorsement thereto (other than in each case, Permitted Liens, except Permitted Liens which are unrecorded Liens, if satisfied). Alon shall pay the premium for the Title Policies, fees for title searches and costs of any endorsements or deletions to the Title Policies. In addition, Alon shall pay for the costs of Surveys, if any, that Alon elects to obtain with respect to the Real Property or any portion thereof.

     6.19 Bank Facilities.

          (a) At the Closing, Alon will pay to, or make available to the Company for payment to, the lenders under the Term Loan Agreement an amount sufficient to repay the principal and accrued but unpaid interest outstanding thereunder as of the Closing Date, together with all Prepayment Penalties and other amounts due to such lenders in connection with such repayment. The Sellers will cause the Company to apply all funds made available to it pursuant to the immediately preceding sentence to the payments to the lenders under the Term Loan Agreement in the manner contemplated by the immediately preceding sentence.

          (b) The Sellers and the Acquired Companies shall comply with all reasonable requests of Alon to assist Alon in its efforts to (i) cause the Revolving Credit Agreement, and the ability of the Company to effect borrowings thereunder and under the credit facilities provided for therein, to remain in full force and effect immediately after and unaffected by the Closing (subject to Alon pledging the Shares as security for the Acquired Companies’ obligations thereunder if and to the extent requested by the lenders thereunder) or (ii) cause all Liens securing indebtedness and other amounts due under the Revolving Credit Agreement to be released effective as of the Closing (subject to Alon’s fulfillment of its obligations under the immediately succeeding sentence). If, as of five Business Days prior to the Closing, the parties have not received the consent of the lenders under the Revolving Credit Agreement to, as of the Closing, (i) keep the Revolving Credit Facility in full force and effect after the Closing, (ii) release all existing guarantors, sureties, and indemnitors (other than the Acquired Companies) of or under the Revolving Credit Agreement, and any related agreements executed in connection with the Revolving Credit Agreement, from their respective obligations, and (iii) fully reconvey the Upper Bluff Property from any recorded deed of trust encumbering the Upper Bluff Property granted in connection with the Term Loan Agreement, then Alon, at the Closing, shall pay to, or make available to the Company for payment to, the lenders under the Revolving Credit Agreement an amount sufficient to repay the principal and accrued but unpaid interest outstanding thereunder as of the Closing Date, together with all Prepayment Penalties and other amounts due to such lenders in connection with such repayment.

          (a) The representations and warranties made in this Agreement shall survive the Closing as follows:

          (i) the representations and warranties in Sections 3.1, 3.2, 4.1(a), 4.2, 4.3(a) and (c), 4.15(c), 5.1(a) and 5.2 shall survive the Closing indefinitely;

          (ii) the representations and warranties in Sections 4.9 and 4.10 shall survive until 90 days after the applicable statute of limitations (subject, in the case of Section 4.9, to the covenants of Alon in Section 8.2(c) regarding granting of extensions of any statute of limitations and its covenant to timely file);

          (iv) all other representations and warranties in this Agreement shall survive the Closing and will not terminate until the first anniversary of the Closing Date (the “First Holdback Termination Date”);

provided, however, that if a written notice of a claim under Section 7.2(a)(i) or 7.2(b)(i) has been given pursuant to Section 7.4 prior to the expiration of the applicable survival period, then the party giving such notice shall continue to have the right to be indemnified with respect to the matter or matters to which such claim relates until such claim has been finally resolved.

          (b) The covenants and agreements of the parties hereto contained in this Agreement shall, subject to the express terms thereof, survive the Closing indefinitely (subject to the expiration of the statute of limitations, or termination of rights under laches or other equitable bar to the matters covered thereby).

          (c) Subject to Section 7.3(a) and (b), for purposes of this Article VII, in determining (i) whether any representation or warranty in this Agreement was true and correct as of any particular date and (ii) the amount of any Damages in respect of the failure of any such representation or warranty to be true and correct as of any particular date, any qualification or limitation as to materiality (whether by reference to Material Adverse Effect or otherwise) contained in such representation or warranty shall be disregarded.

     7.2 Indemnification.

          (a) Each of the Sellers shall, jointly and severally, indemnify and hold harmless Alon, its Affiliates (including the Acquired Companies following the Closing) and each of their respective officers, directors, employees, agents, successors and assigns (the “Alon Indemnified Parties”) from any and all costs, expenses, losses, Liabilities, damages, amounts paid in settlement, claims, interests, awards, judgments, fines, diminution of value and penalties

(including reasonable legal, accounting and consulting fees and expenses and any other reasonable out-of-pocket expenses) actually suffered or incurred by them (including in connection with any action, suit or proceeding brought or otherwise initiated by any of them) (collectively "Damages”), arising out of or resulting from:

               (i) any failure of any representation or warranty made by the Sellers in this Agreement or any of the other Transaction Documents to be true and correct as of the Closing Date; provided however, that each Seller shall be solely liable for a breach by such Seller of the representations and warranties of such Seller in Article III, and such liability shall not be joint;

               (ii) any breach of any covenant of the Sellers contained in this Agreement required to be performed on or prior to the Closing;

               (iii) any breach of any covenant of the Sellers contained in this Agreement, by its terms, required to be performed after the Closing; provided however, that each Seller shall be solely liable for a breach by such Seller of the covenants contained in Section 6.8, and such liability shall not be joint;

               (iv) the Employee Cash Bonuses or the Company Transaction Expenses; and

               (v) the assets, properties, business, operations and Liabilities of the Excluded Company, whether before, on or after the Closing Date, or the existence of Hazardous Materials in or on soils, sediments, surface water or groundwater at, on, under or from such assets and properties, in each case arising from events, occurrences or circumstances prior to the Closing.

          (b) Alon shall indemnify and hold harmless the Sellers and their Affiliates and each of their respective officers, directors, employees, agents, successors and assigns (the “Seller Indemnified Parties”) from any and all Damages arising out of or resulting from:

               (i) any failure of any representation or warranty made by Alon in this Agreement or any of the other Transaction Documents to be true and correct as of the Closing Date;

               (ii) any breach of any covenant of Alon contained in this Agreement; and

               (iii) the conduct of the business and operations of the Acquired Companies after the Closing Date.

     7.3 Other Limitations.

          (a) Except for claims based on fraud or intentional misrepresentations by the Sellers and claims relating to the matters arising under Section 3.1, 3.2, 4.1(a), 4.2 or 4.3(a) and (c) to which the thresholds described in this Section 7.3(a) shall be inapplicable, the Sellers shall have no liability (for indemnification or otherwise) with respect to (i) any individual claim based

54

on an occurrence, event or circumstance relating to the matters described in Section 7.2(a)(i), unless the Damages with respect to such claim exceed $85,000, or (ii) the matters described in Section 7.2(a)(i) until the total of all Damages with respect to such matters exceeds $2,000,000, and then only for the amount by which such Damages exceed $2,000,000 (and for such purpose, no claims excluded under clause (i) shall be included in determining if such aggregated Damages have been met).

          (b) Except for claims based on fraud or intentional misrepresentations by Alon and claims relating to the matters arising under Section 5.1(a) or 5.2, Alon shall have no liability (for indemnification or otherwise) with respect to (i) any individual claim based on an occurrence, event or circumstance relating to the matters described in Section 7.2(b)(i), unless the Damages with respect to such claim exceed $85,000, or (ii) the matters described in Section 7.2(b)(i) until the total of all Damages with respect to such matters exceeds $2,000,000, and then only for the amount by which such Damages exceed $2,000,000 (and for such purpose, no claims excluded under clause (i) shall be included in determining if such aggregated Damages have been met).

          (c) In no event will the Sellers’ liability (for indemnification or otherwise) with respect to the matters in Section 7.2(a)(i) exceed, in the aggregate, $40,000,000, provided however, (i) the Sellers’ liability for claims or causes of action arising from fraud or intentional misrepresentation by the Sellers or arising from the representations and warranties contained in Sections 3.1, 3.2, 4.1(a), 4.2 and 4.3(a) and (c) shall not be limited to $40,000,000 (collectively, with fraud and intentional misrepresentation, the “Excluded Claims”); provided that with respect to the Excluded Claims, in no event shall the aggregate liability of the Sellers for Damages relating to the Excluded Claims exceed the Purchase Price. Notwithstanding the foregoing, if the Alon Indemnified Parties are entitled to recover any Damages relating to claims or causes of action arising from the Excluded Claims or the matters set forth in Sections 7.2(a)(ii), (iii), (iv) or (v), the Alon Indemnified Parties shall first satisfy such claims for indemnification from the Holdback Amount, and if the Holdback Amount is depleted and shall be insufficient to pay the full amount of such Damages, then such amounts shall be paid by the Sellers.

          (d) Only the Sellers’ Representative, on behalf of the Seller Indemnified Parties, may assert a claim for indemnification against Alon pursuant to this Article VII.

          (e) The amount of any Damages subject to indemnification hereunder shall be reduced by any insurance proceeds actually received by the indemnified party from an unrelated third party on account of such Damages prior to the time payment by the indemnifying party is due and payable under this Agreement. In the event that the indemnifying party pays to or on behalf of an indemnified party any amount in respect of Damages subject to indemnification under this Article VII prior to the indemnified party’s receipt, directly or indirectly, of any insurance proceeds on account of such Damages from an unrelated third party which duplicate, in whole or in part, the payment made by the indemnifying party to or on behalf of the indemnified party, the indemnified party shall remit to the indemnifying party an amount equal to the amount of the insurance proceeds actually received by the indemnified party on account of such Damages which duplicate, in whole or in part, the payment made by the indemnifying party to or on behalf of the indemnified party.

          (f) The amount of any Damages subject to indemnification hereunder shall be reduced by the amount of any net Tax benefit actually realized by such Person after the Closing Date on account of such Damages prior to the time payment by the indemnifying party is due and payable under this Agreement. In the event that the indemnifying party pays to or on behalf of an indemnified party any amount in respect of Damages subject to indemnification under this Article VII and, subsequent to such payment the indemnified party actually realizes a net Tax benefit on account of such Damages, the indemnified party shall remit to the indemnifying party an amount equal to the amount of such net Tax benefit actually realized on account of such Damages.

          (g) Notwithstanding anything contained herein to the contrary, the Sellers shall have no liability hereunder for any Damages to the extent specific reserves for such Damages were reflected on the Closing Date Financial Statements and had the effect of reducing the Closing Date Adjusted Book Value.

          (h) If Alon commences any legal proceedings seeking indemnification hereunder, it shall use commercially reasonable efforts (for a period of 30 days) to serve, and join in such action, all of the Sellers potentially liable therefor. Notwithstanding the foregoing, except as expressly set forth herein, each of the Sellers shall be jointly and severally liable to the Alon Indemnified Parties hereunder for 100% of the Damages to which the Alon Indemnified Parties are entitled under this Agreement. Nothing herein shall effect the rights of such Sellers to contribution from the other Sellers.

          (i) Except for matters disclosed in the Sellers’ Disclosure Schedule, to the extent that such matters constitute exceptions to the Sellers’ representations and warranties, and provided, in the case of Alon, it is in material compliance with its representations and warranties in Section 5.7(f) and its covenants in Section 6.3(e), and in the case of the Sellers, they are in material compliance with their respective representations and warranties in Section 4.24(b) and their covenants in Section 6.3(e), no right or remedy of any Person shall be limited in any respect by any investigation made by such Person, the knowledge of such Person of any breach of any provision of this Agreement or any inaccuracy of any representation, warranty or certificate contained herein or delivered pursuant hereto, or the decision of such Person to consummate the transactions contemplated by this Agreement.

     7.4 Procedures Relating to Indemnification Involving Third Party Claims.

          (a) In order for an indemnified party to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any Person not a party to this Agreement against the indemnified party (a “Third Party Claim”), such indemnified party must promptly notify the indemnifying party in writing of the Third Party Claim after receipt by such indemnified party of written notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been actually prejudiced as a result of such failure. The notice of claim shall describe in reasonable detail the facts known to the indemnified party giving rise to such indemnification claim, and the amount or good faith estimate of the amount arising therefrom. Thereafter, the indemnified party shall promptly deliver to the indemnifying party after the indemnified party’s receipt thereof,

56

copies of all notices and documents (including court papers) received by the indemnified party relating to the Third Party Claim. In the event the provisions of Section 8.4 are inconsistent with any provision of this Article VII, the provisions of Section 8.4 shall control with respect to the contest of Tax matters. In the event that more than one Seller is an indemnifying party hereunder, the indemnified party may provide the notices and other communications required pursuant to this Section 7.5 solely to the Sellers’ Representative.

          (b) The Sellers’ Representative, on behalf of the Sellers (if the indemnified party is an Alon Indemnified Party), or Alon (if the indemnified party is a Seller Indemnified Party), as applicable, shall be entitled to assume and control the defense of such Third Party Claim at its expense (or, in the care of the Sellers’ Representative, at the expense of the Sellers) and through counsel of its choice if it gives written notice of its intention to do so to the indemnified party within 30 calendar days of the receipt of the notice of claim from the indemnified party in which case the indemnifying party shall not be liable to the indemnified party for any fees of counsel or any other expenses with respect to the defense of such Third Party Claim; provided, however, that if the indemnified party reasonably determines based upon written advice of counsel that a conflict of interest exists that would make it inappropriate for the same counsel to represent both the indemnified party and the indemnifying party, then the indemnified party shall be entitled to retain its own counsel at the expense of the indemnifying party; provided, further, that the indemnifying party shall not in such event be responsible hereunder for the fees and expenses of more than one firm of separate counsel in connection with any Third Party Claim in the same jurisdiction, in addition to one firm of local counsel. In the event that the Sellers’ Representative or Alon exercises the right to undertake any such defense against such Third Party Claim as provided above, the indemnified party shall cooperate with the Sellers’ Representative or Alon, as applicable, in such defense and make available to the Sellers’ Representative or Alon, as applicable, at the indemnifying party’s expense, all witnesses, pertinent records, materials and information in the indemnified party’s possession or under the indemnified party’s control relating thereto as is reasonably requested by or on behalf of the indemnifying party. Similarly, in the event the indemnified party is, directly or indirectly, conducting the defense against any such Third Party Claim, the indemnifying party shall cooperate with the indemnified party in such defense and make available to the indemnified party, at the indemnifying party’s expense, all such witnesses, records, materials and information in the indemnifying party’s possession or under the indemnifying party’s control relating thereto as is reasonably requested by the indemnified party.

          (c) No compromise or settlement of such Third Party Claim may be effected by either the indemnified party, on the one hand, or the Sellers’ Representative (if the indemnified party is an Alon Indemnified Party) or Alon (if the indemnified party is a Seller Indemnified Party), on the other hand, without the consent of the other (which shall not be unreasonably withheld or delayed). Notwithstanding the foregoing, the Sellers’ Representative (if the indemnified party is an Alon Indemnified Party) or Alon (if the indemnified party is a Seller Indemnified Party) may pay, settle or compromise a Third Party Claim without the written consent of the indemnified party, so long as such settlement includes (i) an unconditional release of the indemnified party from all Liability in respect of such Third Party Claim, (ii) does not subject the indemnified party to any injunctive relief or other equitable remedy, and (iii) does not include a statement or admission of fault, culpability or failure to act by or on behalf of any indemnified party.

     7.5 Other Claims. A claim for indemnification for any matter not involving a Third Party Claim may be asserted by written notice to the Sellers’ Representative (if the indemnified party is an Alon Indemnified Party) or to Alon (if the indemnified party is a Seller Indemnified Party), as applicable, which notice of claim shall describe in reasonable detail the facts known to the indemnified party giving rise to such indemnification claim, and the amount or good faith estimate of the amounts thereof. Such claims shall be paid promptly after receipt of such notice, unless such claim is disputed, in which case it shall be promptly paid upon resolution of such dispute, if any payment is then due.

     7.6 Mitigation of Damages.

          (a) Alon and the Sellers shall cooperate with each other with respect to resolving any claim or liability with respect to which one party is obligated to indemnify the other party hereunder, including by making commercially reasonable efforts to mitigate or resolve any such claim or liability. In the event that Alon or the Sellers shall fail to make commercially reasonably efforts to mitigate or resolve any claim or liability, which efforts are proposed by the other party, then notwithstanding anything else to the contrary contained herein, the other party shall not be required to indemnify any Person for any Damages to the extent the same could reasonably be expected to have been avoided if Alon or the Sellers, as the case may be, had made such efforts following such proposal.

          (b) If any Alon Indemnified Party requests any payment from the Sellers in respect of any Damages pursuant to Section 7.2(a) and the Acquired Companies or the Alon Indemnified Party could have recovered all or a part of such Damages from a third party (a “Potential Contributor”) based on the underlying claim asserted against the Sellers, the Alon Indemnified Party shall assign, on a non-recourse basis and without any representation or warranty, such of its rights to proceed against the Potential Contributor as are necessary to permit the Sellers to recover from the Potential Contributor any amount paid by the Sellers to the Alon Indemnified Parties.

     7.7 Sole and Exclusive Remedy. Should the Closing occur, except as set forth in the Confidentiality Agreement and Section 6.8(b), (i) Alon’s sole and exclusive remedies for any breach of the representations, warranties or covenants of the Sellers under this Agreement and any other Transaction Documents (other than claims of or causes of action arising from fraud or intentional misrepresentation by the Sellers), shall be the remedies provided in this Article VII and Article VIII, and Alon hereby waives, from and after the Closing, any and all other remedies (other than claims of or causes of actions arising from fraud or intentional misrepresentation by the Sellers) which may be available at law or equity for any breach or alleged breach of the representations, warranties and covenants of the Sellers hereunder, and (ii) the Sellers’ sole and exclusive remedies for any breach of the representations, warranties or covenants of Alon under this Agreement and any other Transaction Documents (other than claims of or causes of action arising from fraud or intentional misrepresentation by Alon), shall be the remedies provided in this Article VII and Article VIII, and each of the Sellers hereby waives, from and after the Closing, any and all other remedies (other than claims of or causes of actions arising from fraud or intentional misrepresentation by Alon) which may be available at law or equity for any breach or alleged breach of the representations, warranties and covenants of Alon hereunder. Notwithstanding the foregoing, nothing herein will limit the right of any party to seek injunctive

or other equitable relief for any breach or alleged or threatened breach of any covenant in this Agreement or any other Transaction Document.

ARTICLE VIII
TAX MATTERS

     8.1 Indemnification Obligations With Respect to Taxes.

          (a) The Sellers shall be responsible for, and shall indemnify, defend and hold harmless Alon and the Acquired Companies from and against:

          (i) all Taxes of the Acquired Companies due with respect to periods ending on or prior to the Closing Date including, all Taxes of the Acquired Companies that are due with respect to periods (“Straddle Periods”) that include but do not end on the Closing Date to the extent attributable to the portion of the Straddle Period ending on the Closing Date;

          (ii) all losses resulting from any inaccuracy in or breach of the representations and warranties with respect to Tax matters that are contained in Section 4.9 or in this Article VIII and any covenants contained in this Agreement with respect to Tax matters (without giving effect to any supplement to the Sellers’ Disclosure Schedule delivered after the date hereof or any materiality qualifier), or contained in any certificate or other Transaction Document delivered pursuant hereto; and

          (iii) all losses imposed on or sustained by Alon or its Affiliates (including the Acquired Companies after the Closing Date), directly or indirectly, by reason of or in connection with the foregoing amounts.

          Notwithstanding the foregoing, the Sellers (i) shall only be liable for such amounts to the extent that such amounts are in excess of the amounts, if any, specifically reserved for such amounts (excluding any reserves for deferred Taxes established to reflect timing differences between book and Tax income) on the Closing Date Balance Sheet and (ii) shall in no event have any liability to Alon or any obligation to indemnify Alon for any Tax liability to the extent resulting from or related to the transactions contemplated by Section 2.3(d).

          (b) Alon shall be responsible for, and shall indemnify, defend and hold harmless the Sellers from and against:

          (i) all Taxes of the Acquired Companies that are due with respect to periods commencing after the Closing Date;

          (ii) all Taxes of the Acquired Companies that are due with respect to Straddle Periods to the extent attributable to the portion of the Straddle Period commencing on the day following the Closing Date;

          (iii) all losses resulting from any breach of any covenants of Alon and Alon contained in this Agreement with respect to tax matters or contained in any certificate or other Transaction Document delivered by Alon pursuant hereto;

          (iv) Taxes of the Acquired Companies that are due with respect to the transactions contemplated by Section 2.3(d); and

          (v) all losses imposed on or sustained by the Sellers or their Affiliates, directly or indirectly, by reason or in connection with the foregoing amounts.

          (c) For purposes of this Article VIII, whenever it is necessary to determine the liability for Taxes of the Acquired Companies for a Straddle Period, the determination of the Taxes for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the Closing Date shall be determined by assuming that the Straddle Period consisted of two taxable years or periods, one of which ended at the close of the Closing Date and the other of which began at the beginning of the day following the Closing Date, and items of income, gain, deduction, loss or credit, and state and local apportionment factors of the Acquired Companies for the Straddle Period shall be allocated between such two taxable years or periods on a “closing of the books basis” by assuming that the books of the Acquired Companies were closed at the close of business on the Closing Date; provided however, (i) exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation; and (ii) periodic taxes, such as real and personal property taxes, shall be apportioned ratably between such periods on a daily basis; provided further however, except with respect to any deduction for Employee Cash Bonuses and the Company Transaction Expenses (which shall be allocated to the pre-Closing Straddle Period), Alon and Sellers agree to report all transactions not in the ordinary course of business occurring on the Closing Date after Alon’s purchase of the Shares on Alon’s Federal income tax return to the extent permitted by Treasury Regulation Section 1.1502-76(b)(1)(ii)(B). Notwithstanding anything to the contrary in this Section 8.1, any item of income, gain, deduction, loss or credit with respect to the transactions contemplated by Section 6.14 shall be allocated to the pre-Closing Straddle Period and any items of income, gains, deduction, loss or credit with respect to the transaction contemplated by Section 2.3(d) shall be allocated to the post-Closing Straddle Period.

          (d) Notwithstanding anything to the contrary in this Agreement, the obligations of the Sellers and Alon under this Article VIII shall be unconditional and absolute, and shall not be subject to a deductible, threshold, or similar concept, but the representations of the Sellers set forth in Section 4.9 shall be subject to the $40,000,000 cap in Section 7.3(c) and such representations shall remain in effect until 90 days after the expiration of the applicable statute of limitations as set forth in Section 7.1.

     8.2 Tax Returns.

          (a) Alon shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Acquired Companies that are filed after the Closing Date.

          (b) All Tax Returns that are to be prepared and filed by Alon pursuant to the preceding paragraph and that relate to Taxes for which the Sellers are liable under this Article VIII (including Straddle Period Tax Returns) shall be submitted to the Sellers not later than 15 days prior to the due date for filing of such Tax Returns, taking into account applicable extensions (or if such due date is within 45 days following the Closing Date, as promptly as practicable following the Closing Date). The Sellers shall have the right to review such Tax

Returns and to review all work papers and procedures used to prepare any such Tax Return. If the Sellers’ Representative, within 10 days after delivery of any such Tax Return, notifies Alon in writing that it objects to any of the items in such Tax Return, the parties shall attempt in good faith to resolve the dispute and, if they are unable to do so, the disputed items shall be resolved (within a reasonable time, taking into account the deadline for filing such Tax Return) by an internationally recognized independent accounting firm chosen by both Alon and the Sellers. Upon resolution of all such items, the relevant Tax Return shall be filed on that basis. The costs, fees and expenses of such accounting firm shall be borne equally by Alon and the Sellers.

          (c) Alon shall not (and shall not cause or permit the Acquired Companies to) amend, refile or otherwise modify (or grant an extension of any statute of limitation with respect to) any Tax Return relating in whole or in part to the Acquired Companies with respect to any taxable year or period ending on or before the Closing Date or with respect to any Straddle Period without the prior written consent of the Sellers’ Representative, which consent may not be unreasonably withheld or delayed. The Sellers shall not amend, refile, or otherwise modify any such Tax Return if such action could have an adverse affect on the liability of the Acquired Companies, without the prior written consent of Alon, which consent may not be unreasonably withheld or delayed.

          (d) All sales, use, transfer and other similar Taxes, including any stock transfer stamp Taxes resulting from the sale of the Shares, shall be borne jointly and severally by the Sellers.

     8.3 Contest Provisions.

          (a) In the event (i) any Seller or their Affiliates or (ii) Alon or its Affiliates receive notice of any pending or threatened Tax audits or assessments or other disputes concerning Taxes with respect to which the other party may incur liability under this Article VIII, the party in receipt of such notice shall promptly notify the other party of such matter in writing, provided that failure to comply with this provision shall not affect a party’s right to indemnification hereunder unless such failure materially adversely affects the party’s ability to challenge such Tax audits or assessments.

          (b) The Sellers shall have the sole right to represent the interests of the Acquired Companies in any Tax audit or administrative or court proceeding relating to any Tax for any taxable period ending on or before the Closing Date, and to employ counsel of their choice at their expense. Notwithstanding the foregoing, the Sellers shall not be entitled to settle, either administratively or after the commencement of litigation, any claim for Taxes with respect to any Tax Return of any of the Acquired Companies which would adversely affect the liability for Taxes of Alon or the Acquired Companies for any period after the Closing Date to any extent (including, but not limited to, the imposition of income Tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of the loss or credit carry forwards) without the prior written consent of Alon, which consent shall not be unreasonably withheld or delayed.

          (c) Alon shall have the sole right to represent the interests of the Acquired Companies in any Tax audit or administrative or court proceeding relating to Taxes with respect to taxable periods including (but not ending on) or beginning after the Closing Date and to employ counsel of its choice at its expense, provided that Alon shall not be entitled to settle, either administratively or after the commencement of litigation, any claim regarding Taxes that would adversely affect the liability of the Sellers for any Taxes for any period ending on or before the Closing Date or for any Straddle Period, without the prior consent of the Sellers’ Representative, which consent shall not be unreasonably withheld or delayed and shall not be required to the extent that Alon has indemnified the Sellers against the effects of such settlement. Where consent to a settlement is withheld by the Sellers’ Representative pursuant to this section, the Sellers may continue or initiate any further proceedings at their own expense, Alon shall not be obligated to incur any further expenses in such matter and the liability of Alon, after giving effect to this Agreement, shall not exceed the liability that would have resulted from the settlement or amended return.

     8.4 Assistance and Cooperation. After the Closing Date, the Sellers, on the one hand, and Alon, on the other hand, shall (and shall cause their respective Affiliates to): (a) assist the other party in preparing and filing any Tax Returns or reports which such other party is responsible for preparing and filing in accordance with this Article VIII; (b) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax Returns of the Acquired Companies; (c) make available to the other and to any taxing authority as reasonably requested all information, records, and documents relating to Taxes of the Acquired Companies; (d) provide timely notice to the other in writing of any pending or threatened Tax audits or assessments of the Acquired Companies for taxable periods for which the other may have a liability under this Article VIII; and (e) furnish the other with copies of all correspondence received from any taxing authority in connection with any Tax audit or information request with respect to any such taxable period.

     8.5 Retention of Records. After the Closing Date, the Sellers, Alon and the Acquired Companies will preserve all information, records or documents relating to liabilities for Taxes of the Acquired Companies until six months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes, provided that neither party shall dispose of any of the foregoing items without first offering such items to the other party.

     8.6 Refunds and Tax Benefit. Except to the extent included as current assets in the Closing Date Adjusted Book Value, any Tax refunds that are received by Alon or the Acquired Companies, and any amount credited against Tax to which Alon or the Acquired Companies become entitled, that relate to the Tax periods or portions thereof ending on or before the Closing Date (including, without limitation, the pre-Closing Straddle Period) shall be for the account of the Sellers, and Alon shall pay to the Sellers, in their Pro Rata Portions, any such refund or the amount of any such credit within 15 days after receipt or entitlement thereto. In addition, to the extent that a claim for refund or a proceeding results in a payment or credit against Tax by a taxing authority to Alon or the Acquired Companies of any amount accrued as a current liability in the Closing Date Adjusted Book Value, Alon shall pay such amount to the Sellers, in their Pro Rata Portions, within 15 days after receipt or entitlement thereto.

     8.7 Other Provisions. The provisions of this Article VIII (and not Section 7.2) shall govern all indemnity claims with respect to Tax matters of the Acquired Companies and the Stock Purchase pursuant to this Agreement. All indemnity payments under this Agreement and any adjustment to any payment of the Purchase Price as described in Section 2.3 shall be treated as an adjustment to the Purchase Price paid for the Shares for tax purposes.

     9.4 Remedies in the Event of Certain Material Adverse Effects on the Company.

          (a) If after the date hereof and prior to the Closing or the termination of this Agreement, there shall be an event, circumstance or occurrence that causes the failure of any condition to the obligation of Alon set forth in Section 9.2(a), (b), or (f) (a “Pre-Closing Adverse Change”) and the Damages that could reasonably be expected to result from such Pre-Closing Adverse Change (the "Damage Estimate") are in the aggregate no more than $40,000,000, then the Sellers may elect to extend the Termination Date to a date no more than 30 days after the occurrence of such Pre-Closing Adverse Change and (i) if the Damages or other effects resulting from such Pre-Closing Adverse Change are curable, to cure the Damages or other effects resulting from such Pre-Closing Adverse Change in all material respects, or (ii) in the event that such Damages or effects are not curable, or the Sellers elect not to cure such Damages or effects, the Sellers may elect to proceed with the Closing, subject to and in accordance with subsection (c) below. For purposes of determining whether the Damage Estimate is no more than $40,000,000 or more

than $40,000,000 in the context of determining whether Alon is obligated to proceed with the Closing pursuant to Section 9.4(c) below, the Damage Estimate shall be determined without regard to any insurance, condemnation or other proceeds. For purposes of determining the amount of any adjustment to the Purchase Price (and, if applicable, the Cash Payment) pursuant to this Section 9.4, the Damage Estimate shall exclude any Damages to the extent that such Damages shall have or have had the effect of reducing the Purchase Price (and the Cash Payment) pursuant to Section 2.3(a) and shall be reduced by the amount of any insurance, condemnation or other proceeds previously received by the Acquired Companies (and, if so received prior to the Closing, retained by the Acquired Companies), and not included in the Closing Date Adjusted Book Value. If following any reduction in the Purchase Price (and, if applicable, the Cash Payment) pursuant to this Section 9.4, the Acquired Companies receive any insurance, condemnation or other proceeds which duplicate, in whole or in part, such reduction in the Purchase Price (and, if applicable, the Cash Payment), Alon shall remit to the Sellers in their Pro Rata Portions an amount equal to the amount of such insurance, condemnation or other proceeds actually so received by the Acquired Companies which duplicate, in whole or in part, such reduction in the Purchase Price (and, if applicable, the Cash Payment).

          (b) If after seven days following the election set forth in subsection (a)(ii) above, the parties have not mutually agreed, after using their good faith reasonable best efforts, to the amount of the Damage Estimate, the parties shall pursue such valuation and/or dispute resolution mechanisms as may be reasonably appropriate and available to the parties to permit in all due haste a determination of the amount of the Damage Estimate prior to the Termination Date, such mechanism to include each party designating one independent expert in the profession most relevant to the nature of the Damages.

     (c) (i) If prior to the Termination Date (as extended pursuant to this Section 9.4, if applicable), the parties (or their independent experts, if applicable) have mutually determined the amount of the Damage Estimate and such amount is no more than $40,000,000, and all other conditions set forth in Sections 9.1, 9.2 and 9.3 have been satisfied or waived, the parties shall proceed with the Closing and the Purchase Price (and Cash Payment) shall be reduced by the agreed amount of the Damage Estimate and the relevant condition set forth in Section 9.2, to the extent not satisfied as a result of the Post-Closing Adverse Change, shall be deemed satisfied. If, prior to the Termination Date (as extended pursuant to this Section 9.4, if applicable), the parties (or their independent experts, if applicable) have mutually determined that the Damage Estimate is greater than $40,000,000 (whether or not the specific amount of the Damage Estimate has been determined) the relevant condition set forth in Section 9.2 shall be deemed to not have been satisfied and Alon shall have all remedies available to it under this Agreement.

          (ii) If, prior to the Termination Date (as extended pursuant to this Section 9.4, if applicable), neither the parties nor their independent experts have mutually determined that the Damage Estimate is either more than $40,000,000 or not more than $40,000,000, the Sellers may elect to extend the Termination Date by an additional fifteen days and the parties’ experts shall promptly provide their respective best and good faith estimate of the Damage Estimate to a third independent expert mutually selected by the parties’ experts (the “Third Expert”), together with all information, materials, work

papers and other data utilized or developed by the parties’ experts in connection with their efforts to determine the amount of the Damage Estimate.

     (A) If, prior to the Termination Date (as further extended pursuant to this clause (ii)), the Third Expert shall have determined the amount of the Damage Estimate, and such amount is no more than $40,000,000, and all other conditions set forth in Sections 9.1, 9.2 and 9.3 have been satisfied or waived, the parties shall proceed with the Closing and the Purchase Price (and Cash Payment) shall be reduced by the amount of the Damage Estimate (so determined) and the relevant condition set forth in Section 9.2, to the extent not satisfied as a result of the specific event, circumstance or occurrence giving rise to the Damage Estimate, shall be deemed satisfied.

     (B) If, prior to the Termination Date (as further extended pursuant to this clause (ii)), the Third Expert shall have determined that the Damage Estimate is greater than $40,000,000 (whether or not the specific amount of the Damage Estimate has been determined), the relevant condition set forth in Section 9.2 shall be deemed to not have been satisfied and Alon shall have all remedies available to it under this Agreement.

     (C) If, prior to the Termination Date (as further extended pursuant to this clause (ii)), the Third Expert shall have determined that the Damage Estimate is less than $40,000,000, but has not determined the specific amount of the Damage Estimate, then if all other conditions set forth in Sections 9.1, 9.2 and 9.3 have been satisfied or waived, (A) the parties shall proceed with the Closing, (B) the relevant condition set forth in Section 9.2, to the extent not satisfied as a result of the Post-Closing Adverse Change, shall be deemed satisfied, (C) the Purchase Price (and Cash Payment), shall be reduced by the Third Expert’s good faith best estimate of the amount of the Damage Estimate, and (D) the Third Expert shall, within 30 days after the Closing, make a final determination of the amount of the Damage Estimate. If the final amount of the Damage Estimate determined by the Third Expert in such 30 day period exceeds the reduction to the Purchase Price (and Cash Payment) made at Closing pursuant to the proceeding sentence, the Sellers shall promptly pay the amount of the difference to Alon. If the final amount of the Damage Estimate determined by the Third Expert is less than such reduction to the Purchase Price (and Cash Payment) made at Closing, Alon shall promptly pay the amount of the difference to the Sellers.

          (iii) If, prior to the Termination Date (as extended pursuant to this Section 9.4, if applicable) the parties or their independent experts have mutually determined that the Damage Estimate is no more than $40,000,000, but neither the parties nor their independent experts have mutually agreed to the specific amount of the Damage Estimate, then if all other conditions set forth in Sections 9.1, 9.2 and 9.3 have been satisfied or waived, (A) the parties shall proceed with the Closing, (B) the relevant condition set forth in Section 9.2, to the extent not satisfied as a result of the Post-Closing Adverse Change shall be deemed satisfied, (C) the Purchase Price (and Cash Payment) shall be reduced by the average of each parties’ expert’s good faith best estimate of the

amount of the Estimated Damages, and (D) the parties’ experts shall promptly provide their best and good faith estimate of the Damage Estimate to the Third Expert, together with all information, materials, work papers and other data utilized or developed by the parties’ experts in connection with their efforts to determine the amount of the Damage Estimate. The Third Expert shall make a final determination of the amount of the Damage Estimate which determination shall be (1) either the amount of the Damage Estimate proposed by either party’s expert or an amount between such two proposals and (2) determined by such Third Expert no later than 30 days after the Closing Date. If the final amount of the Damage Estimate so determined exceeds the reduction to Purchase Price (and Cash Payment) made at Closing pursuant to the preceding sentence, the Sellers shall promptly pay the amount of the difference to Alon. If the final amount of the Damage Estimate so determined is less than such reduction to the Purchase Price (and Cash Payment) made at Closing, Alon shall promptly pay the amount of the difference to the Sellers.

          (d) For all purposes of Section 9.4(c), in the event that any Damage Estimate provided by an expert engaged pursuant to this Section 9.4 shall consist of a range of possible amounts of the Damage Estimate, the midpoint amount in such range shall be deemed to be the Damage Estimate provided by such expert.

          (e) Any mutual determination by the parties or the parties’ experts regarding the Damage Estimate, and any determination by the Third Expert regarding the Damage Estimate, shall be final and binding on the parties. Each party shall bear all costs and expenses of its respective expert and the costs and expenses of the Third Expert shall be shared equally by the parties. Each party shall act in good faith with respect to all matters arising under this Section 9.4, including in negotiating and determining the amount of any Damage Estimate and in its selection of and dealings with its respective independent expert. Each party will fully cooperate with the other party and each of the experts engaged pursuant to this Section 9.4 in the efforts to determine the amount of any Damage Estimate, including the provision of access to any property or facility of any affected Acquired Company and the provision of all information, materials, documents and other data relevant to such determination.

provided, however, that the right to terminate this Agreement pursuant to this subsection (a) shall not be available to the Sellers if the breach of or noncompliance with this Agreement by any of them shall have proximately contributed to the failure referenced in this subsection (a); or

          (b) there has been a material breach by Alon of any representation, warranty, covenant or agreement of Alon contained in this Agreement that is not curable or, if curable, is not cured prior to the earlier of (i) 30 days after written notice of such breach is given by the Sellers to Alon and (ii) the Termination Date; provided that no Seller is then in material default or breach of this Agreement.

Copies to such persons shall also be made with respect to notices sent to the Sellers’ Representative post-Closing, with notices sent to the Sellers’ Representative at the address set forth in the notice of appointment required by Section 6.12,

or to such other address as the Person to whom notice is given may have previously furnished to the other in writing in the manner set forth above; provided that notice of any change of address shall be effective only upon receipt thereof.

     11.4 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California, regardless of the laws or rules that might otherwise govern under applicable principles of conflicts of laws thereof. In the event of the bringing of any action or suit by a party hereto against another party hereunder arising out of or relating to this Agreement, then in that event, (i) the sole forum for resolving such disputes shall be the federal courts located in Orange County, California, and each of the parties hereby irrevocably submits to such exclusive jurisdiction, and (ii) the prevailing party in such action or dispute, whether by final judgment, or out of court settlement shall be entitled to have and recover of and from the non-prevailing parties all costs and expenses of suit, including actual attorneys’ fees. Any judgment or order entered in any final judgment shall contain a specific provision providing for the recovery of all costs and expenses of suit, including actual attorneys’ fees (collectively "Costs”) incurred in enforcing, perfecting and executing such judgment. For the purposes of this paragraph, Costs shall include, without limitation, attorneys’ fees, costs and expenses incurred in (a) appeals, (b) post-judgment motions, (c) contempt proceeding, (d) garnishment, levy, and debtor and third party examination, (e) discovery, and (f) bankruptcy litigation.

     11.5 Specific Performance. The parties recognize that if the Sellers refuse to perform under the provisions of this Agreement, monetary damages alone will not be adequate to compensate Alon for its injury. Alon shall therefore be entitled, in addition to any other remedies that may be available, to obtain specific performance of this Agreement. If any action is brought by Alon to enforce this Agreement, the Sellers shall waive the defense that there is an adequate remedy at law. In the event of a default by the Sellers which results in the filing of a lawsuit for damages, specific performance, or other remedies, Alon shall be entitled to reimbursement from the Sellers of reasonable legal fees and expenses incurred by Alon.

     11.6 Construction. The headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. Unless the context clearly requires otherwise “or” is not exclusive, and “includes” means “includes, but is not limited to.”

     11.7 Counterparts. This Agreement may be executed in counterparts, including facsimile counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission shall be effective delivery of a manually executed counterpart to this Agreement.

     11.8 Parties In Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Agreement, including any employee or former employee of the Acquired Companies (or any beneficiary or dependent thereof), except that each Alon Indemnified Party and Seller

Indemnified Party shall be a third party beneficiary with respect to Article VII and shall be entitled to the rights and benefits of, and to enforce, the provisions thereof.

     11.9 Waiver. No waiver of any breach of the provisions of this Agreement will be deemed to have been made by any party, unless such waiver is expressed in writing and signed by the party against which it is to be enforced. The waiver by any party of any right under this Agreement or to a remedy for the breach of any of the provisions herein shall not operate nor be construed by the breaching party as a waiver of the non-breaching party’s remedies with respect to any other or continuing or subsequent breach.

     11.10 Amendments. No amendment or modification in respect of this Agreement shall be effective unless it shall be in writing and signed by the parties hereto.

     11.11 Further Assurances; Post Closing Cooperation. The parties agree (a) to furnish upon request to each other such further information, (b) to execute and deliver to each other such other documents, and (c) to do such other acts and things, all as any other party hereto may reasonably request for the purpose of carrying out the transactions contemplated by this Agreement. After the Closing Date, Alon shall provide the Sellers reasonable access, during normal business hours and on at least three Business Day’s prior notice, to the records of the Acquired Companies relating to periods prior to the Closing Date for any reasonable purpose. After the Closing, Alon shall cause the Acquired Companies to fulfill all of their obligations hereunder, and shall guarantee such performance.

     11.12 Cumulative Remedies. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any other rights, remedies, powers and privileges provided by law.

     11.13 Disclosure . Notwithstanding anything to the contrary contained in the Disclosure Schedules or in this Agreement, the information and disclosures contained in any section of the Disclosure Schedule shall be deemed to be disclosed and incorporated by reference in any other section of the Disclosure Schedule as though fully set forth in such section of the Disclosure Schedule to the extent that the applicability of such information and disclosure is reasonably apparent on its face. The fact that any item of information is disclosed in any section of the Disclosure Schedule shall not be construed to mean that such information is required to be disclosed by this Agreement. Such information and the dollar thresholds set forth herein shall not be used as a basis for interpreting the terms “material” or “Material Adverse Effect” or other similar terms in this Agreement.
