NOW THEREFORE, in consideration of the mutual promises, covenants and agreements contained herein, the adequacy and sufficiency of all of which are hereby acknowledged, the Parties agree as follows:

1.                                      Capitalized Terms.  Capitalized terms not otherwise defined in this Agreement shall be defined as set forth in the Merger Agreement.

2.                                      Termination of the Merger Agreement.  Huntsman has validly terminated the Merger Agreement in accordance with its terms pursuant to Section 7.1 of the Merger Agreement.  Promptly following the Effective Date, Hexion shall take all actions reasonably required to terminate any tender offers for securities of Huntsman and its affiliates then outstanding in connection with the Transactions contemplated by the Merger Agreement, including the Debt Offer.

4

Apollo entities set forth in Paragraph 3 of Annex A attached hereto satisfies any portion of such amount, Hexion agrees to use diligent efforts to obtain reimbursement or other recovery from its insurance providers; provided, however, that this obligation to use diligent efforts shall not be deemed to require Hexion to waive or compromise its rights to insurance coverage for any other liability or claim.  Any amounts so recovered, net of expenses incurred for such recovery, shall be promptly paid by Hexion pro rata to the Apollo entity or entities set forth in Paragraph 3 of Annex A attached hereto up to the amount that such entity has paid in satisfaction of the payment obligation set forth in this paragraph.

Harris) and the Hexion Parties (except for Craig O. Morrison) to pay such amount shall continue in full force and effect.

7.                                      Indemnification.

(a)                                  Huntsman shall indemnify and hold the Hexion Releasees and Apollo Releasees harmless from any claim for indemnification or contribution or any

12

other claim asserted against either the Hexion Releasees or the Apollo Releasees by any of Credit Suisse, Cayman Islands Branch, Credit Suisse Securities (USA) LLC, Deutsche Bank AG Cayman Islands Branch, Deutsche Bank AG New York Branch, Deutsche Bank Securities Inc., and Deutsche Bank Trust Company Americas, or any of their respective affiliates or assignees (collectively, the “Banks”), that in any way relates to or arises out of any claims made by the Huntsman Parties against the Banks (collectively, the “Indemnified Matters”).  Such indemnification by Huntsman shall include but is not limited to the claim for indemnification asserted by the Banks against Hexion in the New York Action Against the Banks, and the claim for contribution asserted by the Banks against the Apollo Parties in the Texas Action Against the Banks; provided, however, that Huntsman will not be required to indemnify the Apollo Parties or the Hexion Parties for any legal fees or expenses incurred by the Banks.  The aggregate amount paid by Huntsman to the Hexion Releasees and/or the Apollo Releasees pursuant to the terms of this paragraph shall not exceed the amounts of Huntsman’s recovery collected, if any, in the Texas Action Against the Banks net of attorney fees, costs and expenses related to the Texas Action Against the Banks.  Notwithstanding the foregoing, the Hexion Releasees and Apollo Releasees shall bear and not be indemnified for their own attorneys fees and expenses in defending such Banks’ claims.

(b)                                 In furtherance of but without limiting its indemnification obligation, Huntsman agrees that it will reduce or credit, against any judgment or settlement that it may obtain against any of the Banks, an amount equal to the full amount of any judgment that the Banks may at any time obtain or have obtained against any of the Hexion Releasees or Apollo Releasees on any claim, including any claim for

13

contribution or indemnification, that in any way relates to or arises out of any of the Indemnified Matters.

(c)                                  In the event Huntsman settles any claim against any of the Banks that in any way relates to or arises out of any of the Indemnified Matters, Huntsman shall obtain a release in favor of the Hexion Releasees and the Apollo Releasees of any and all liability that any of the Hexion Releasees or the Apollo Releasees may have to any of the Banks that arises out of the Indemnified Matters.

(d)                                 Huntsman shall take all appropriate and necessary actions (including delaying distribution of amounts payable under a judgment) so as to assure the full and complete effectuation of the protections set forth in this section of the Settlement Agreement.  It is agreed that any breach of the obligations set forth in this Paragraph 7 will result in irreparable injury to the Hexion Releasees and the Apollo Releasees and that Huntsman shall be subject to (in addition to and without limiting any other available remedies) injunctive relief and shall be liable for all attorneys’ fees, costs and expenses incurred in connection with procuring injunctive relief or otherwise enforcing the obligations set forth herein.

(e)                                                                                  The Hexion Releasees and the Apollo Releasees agree to use diligent efforts to vigorously defend and contest any claim, action or proceeding in respect of which indemnification could be sought under this Paragraph 7.  The Hexion Releases and the Apollo Releasees agree that they will not settle, compromise or consent to the entry of any judgment with respect to any claim, action or proceeding in respect of which indemnification could be sought under this Paragraph 7 without the prior written consent of the Huntsman Parties, which consent shall not be unreasonably withheld.

14

16

proceeding or to give appropriate testimony or file any necessary documents in any legal or regulatory proceeding or as may be required by law, each of the Parties will use its commercially reasonable efforts not to make any public statements (including in any filing with the SEC or any other regulatory or governmental agency, including any stock exchange) that are inconsistent with, or otherwise contrary to, the jointly approved statements in the press release(s) issued pursuant to this Paragraph 11.

12.                               Choice of Law.  This Agreement and all matters arising out of or relating to this Agreement, and all transactions and events contemplated hereby or thereby, shall be governed by, and construed, performed, and enforced in accordance with, the laws of the State of Delaware, without giving effect to its conflicts or choice of law rules.

December    , 2008

Dear                      :

This letter memorializes our agreement as of the Effective Date of the Settlement Agreement and Release dated December      , 2008 between and among the Huntsman Parties, the Hexion Parties, and the Apollo Parties (capitalized terms not otherwise defined in this letter are used as defined in the Settlement Agreement and Release), that Huntsman shall pay the Apollo Parties an amount in cash equal to 20% of the value of any cash and noncash consideration that is in excess of $500 million ($500,000,000) that Huntsman may obtain or receive in settlement in connection with any claims made by Huntsman against the Banks arising from or relating to the Merger Agreement, the Transactions referred to therein (including but not limited to the Financing), and related matters, such claims including but not limited to the Texas Action Against the Banks (the “settlement”), after Huntsman first recovers its attorneys’ fees, costs, and expenses in making that claim; provided, however, that:

(1)                                  in no circumstance shall the aggregate amount of any payments owed by Huntsman to the Apollo Parties under this letter exceed $425 million ($425,000,000);

(2)                                  in the event trial commences in the Texas Action Against the Banks, any interest on the part of the Apollo Parties shall terminate immediately, and Huntsman shall not owe any portion of any subsequent recovery to the Apollo Parties under this letter; and

(3)                                  in the event that Huntsman or any of its subsidiaries issues a security or debt instrument to any of the Banks in connection with the settlement, the amount of consideration deemed to be obtained or received by Huntsman in connection therewith shall be the excess of any of the value of the consideration provided by the Banks over the value of the security or debt instrument issued.

For the purposes of this letter, the value of (1) any consideration consisting of securities listed on a national securities exchange or traded on the NASDAQ shall be equal to the average closing price per share of such security as reported on such exchange or NASDAQ for the 10 trading days prior to the date of settlement; and (2) any other form of noncash consideration shall be the full market value of that noncash consideration as determined by a nationally recognized independent

investment banking firm mutually selected within three business days after the Huntsman Parties advise the Apollo Parties of the settlement, by the Huntsman Parties and the Apollo Parties, which determination shall be made by such investment banking firm within 15 business days after the date of their engagement.  The determination of the investment banking firm shall be binding upon the parties.

Payment in full of all amounts due to Huntsman under the Settlement Agreement is a condition precedent to the obligation to pay any sums of money pursuant to this letter for the benefit of the Huntsman Parties and if such condition precedent is not met prior to April 1, 2009, this letter shall terminate.  The obligations of this letter are also separate and severable, in their entirety, from the Settlement Agreement.  The Huntsman Parties shall not challenge in any way the validity or enforceability of this letter or any provision thereof.  In the event that this letter or any provision hereof is invalid or unenforceable, or fails for any reason, it shall have no effect on the validity or enforceability of the Settlement Agreement.

The provisions of the Settlement Agreement relating to Choice of Law and Jurisdiction shall also apply to this letter.

This letter may be executed simultaneously or in actual or telecopied counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same letter.
