        2.1    Purpose.    This Plan herein set forth has been created for the primary purpose of providing benefits for certain key employees that cannot be provided under the Huntsman Defined Benefit Pension Plan, the Huntsman Money Purchase Pension Plan and the Huntsman Salary Deferral Plan because of certain limitations of current law and plan design. The Plan is intended to be an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees for purposes of the Employee Retirement Income Security Act of 1974, as amended ("ERISA") and shall be administered as such.

ARTICLE IV

DEFINED BENEFIT PENSION PLAN SUPPLEMENTAL BENEFIT

        4.1    Benefit.    A Vested Defined Benefit Pension Plan Member (or in the case of death benefits, the Beneficiary of a Vested Defined Benefit Pension Plan Member) who becomes eligible to receive benefits under the Defined Benefit Pension Plan on or after the Effective Date of this Plan shall be entitled to a benefit under this Plan equal to the positive difference, if any, between (a) and (b) below:

The determination of the benefits payable to the Member under this Article and any present value determinations shall be made by an actuary using the assumptions and methods used under the Defined Benefit Pension Plan for similar determinations. To the extent the Vested Defined Benefit Plan Member is entitled to receive benefits under more than one plan that is a Defined Benefit Pension Plan hereunder, the Plan Administrator shall determine the manner in which the benefit hereunder shall be determined as to each Defined Benefit Pension Plan so as to accomplish the intent of this Plan without providing duplicate benefits for the same service.

        4.2    Payment of Benefits.    Benefits payable under this Article IV shall be paid beginning as of the date you first became eligible to begin receiving a normal retirement benefit from the Defined Benefit Pension Plan; provided, however, you may change the date as of which the benefit becomes payable by submitting a written request to the Plan Administrator. The change will not be effective unless the Plan Administrator, in its sole discretion, approves the proposed date, the proposed date is the date as of which benefits will commence to the Member under the Defined Benefit Pension Plan and the request is received at least 30 days prior to the Termination Date. The normal form of the benefit is a life annuity for the life of the Member, payable monthly. The amount due the Member shall be paid in one of the following forms as selected by the Member in writing (which if it is not the normal form shall be the actuarial equivalent of the benefit expressed in the normal form):

In the event the Member makes no election as to the form of payment, the benefits of the Member shall be paid to the Member in the form of a life annuity. Notwithstanding the foregoing, in the event the present value of the benefits under this Article with respect to a Defined Benefit Pension Plan do not exceed $25,000, such benefits shall be paid in the form of a single lump sum payment to the Member without regard to the form of payment elected by the Member.

        Any death benefits payable under this Plan on account of the death of a Member prior to the commencement of benefits under this Plan shall be paid to the spouse of the Member in the form of an annuity over the life of the spouse; provided, however, in the event the present value of the benefits under this Article with respect to a Defined Benefit Pension Plan do not exceed $25,000, the benefits shall be paid in the form of a single lump sum payment to the spouse of the Member. There are no preretirement death benefits under this plan for a Member who is not married on the date of death.

        4.3    Change in Form of Payment.    A Member may change his/her election of the form of payment by submitting an election form to the Plan Administrator at least 30 days prior to the Commencement Date; provided such election shall not be effective unless the Plan Administrator, in its sole discretion, approves the form of payment selected.

        5.3    Accounting Device Only.    The account shall be utilized solely as a device for the measurement and determination of the amounts to be paid to the Member under this Plan. The account shall not constitute or be treated as a trust fund of any kind.

        5.5    Form of Payment.    The amount due the Member shall be paid in one of the following forms as elected by the Member in writing:

        In the event payment is made in installments, the account used to measure the amount due the Member shall continue to be adjusted for interest under rules prescribed by the Plan Administrator as provided in Section 5.1(b). In the event no form of payment is elected, the amount due the Member shall be paid in a form of installments over a 10 year period. Notwithstanding the foregoing, in the event the amount due the Member under this Article does not exceed $25,000, such benefits shall be paid in the form of a single lump sum payment to the member without regard to the form of payment elected by the Member.

        5.6    Requirements for Valid Election as to Form of Payment.    An election of a Member as to the form of payment (other than an election made at the time the Member became a Member of this Plan) shall not be valid (I) unless submitted in writing to the Plan Administrator at least 30 days prior to the Commencement Date and (ii) unless the Plan Administrator, in its sole discretion, approves the form of payment selected.

        5.7    Payment to Beneficiary.    In the event a Member dies before receiving his/her full benefit under this Article, the Employer shall pay any remaining amount due on behalf of the Member hereunder to the Beneficiary of the Member. Such payment shall be in the form of a single cash payment and shall be paid within 60 days of the date of death. A Member may designate a Beneficiary on the form prescribed by and delivered to the Plan Administrator. If no Beneficiary is properly designated under this Plan, then the Beneficiary shall be the person entitled under the terms of the Money Purchase Pension Plan to receive any death benefits payable under the Money Purchase Pension Plan on account of the death of that Member.

The benefits payable under this Article VI shall be paid in the form of a single cash lump sum payment within 60 days of the date of the Change of Control.


ARTICLE VII

OTHER BENEFITS TAKEN INTO ACCOUNT

        For purposes of this Plan, the Employer shall take into account and credit against its obligations hereunder with respect to any Defined Benefit Pension Plan Member or Money Purchase Pension Plan Member (or the Beneficiary of such a Member), as the case may be, the actuarial value of any payments or benefits provided said Member that was intended to compensate said Member for benefits that could not be provided under the Defined Benefit Pension Plan or the Money Purchase Pension Plan, as the case may be, but are intended to be provided under this Plan. Any such payments or benefits shall be disregarded in calculating the compensation of a Member that is taken into account for purposes of calculating the unrestricted benefit or contribution allocation under Sections 4.1(a) or 5.1(a).


ARTICLE VIII

CLAIMS AND REVIEW PROCEDURES

        8.1    Claims Procedure.    The Plan Administrator shall notify the Member or beneficiary ("claimant") in writing, within ninety (90) days of his or her written application for benefits, of his or her eligibility or noneligibility for benefits under the Plan. If the Plan Administrator determines that a claimant is not eligible for benefits or full benefits, the notice shall set forth (1) the specific reasons for such denial, (2) a specific reference to the provisions of the Plan on which the denial is based, (3) a description of any additional information or material necessary for the claimant to perfect his or her claim, and a description of why it is needed, and (4) an explanation of the Plan's claims review procedure and other appropriate information as to the steps to be taken if the claimant wishes to have the claim reviewed. If the Plan Administrator determines that there are special circumstances requiring additional time to make a decision, the Plan Administrator shall notify the claimant of the special circumstances and the date by which a decision is expected to be made, and may extend the time for up to an additional ninety-day period.

8


        8.2    Review Procedure.    If a claimant is determined by the Plan Administrator not to be eligible for benefits, or if the claimant believes that he or she is entitled to greater or different benefits, the claimant shall have the opportunity to have such claim reviewed by the Plan Administrator by filing a petition for review with the Plan Administrator within sixty (60) days after receipt of the notice issued by the Plan Administrator. Said petition shall state the specific reasons which the claimant believes entitle him or her to benefits or to greater or different benefits. Within sixty (60) days after receipt by the Plan Administrator of the petition, the Plan Administrator shall afford the claimant (and counsel, if any) an opportunity to present his or her position to the Plan Administrator orally or in writing, and the claimant (or counsel) shall have the right to review the pertinent documents. The Plan Administrator shall notify the claimant of its decision in writing within the sixty-day period, stating specifically the basis of its decision, written in a manner calculated to be understood by the claimant and the specific provisions of the Plan on which the decision is based. If, because of the need for a hearing, the sixty-day period is not sufficient, the decision may be deferred for up to another sixty-day period at the election of the Plan Administrator, but notice of this deferral shall be given to the claimant. In the event of the death of a claimant, the same procedures shall apply to the claimant's beneficiaries.


ARTICLE IX

ADMINISTRATION OF THE PLAN

        9.1    Plan Administration.    The Plan Administrator shall have the full authority to interpret and construe the Plan and to issue such administrative procedures as it deems appropriate. The Plan Administrator shall have the duty and responsibility of maintaining records, making the requisite calculations and disbursing the payments hereunder. The Plan Administrator's interpretations, determinations, regulations and calculations shall be final and binding on all persons and parties concerned.

        9.2    Amendment and Termination.    

        9.3    Payments.    The Employer will pay all benefits arising under this Plan. There shall be deducted from each payment any federal, state or local withholding or taxes or charges which may be required under applicable law as determined by the Employer. The benefits hereunder shall not be

9


treated as compensation from the Employer for purposes of any other benefit plan or program of the Employer unless specifically designated as compensation in such other benefit plan or program.

        9.4    Non-assignability of Benefits.    The benefits payable hereunder or the right to receive future benefits under the Plan may not be anticipated, alienated, pledged, encumbered, or subjected to any charge or legal process, and if any attempt is made to do so, or a person eligible for any benefits becomes bankrupt, the interest under the Plan of the person affected may be terminated by the Plan Administrator which, in its sole discretion, may cause the same to be held or applied for the benefit of one or more of the dependents of such person or make any other disposition of such benefits that it deems appropriate.

        9.5    Status of Plan.    Nothing contained herein shall be construed as providing for assets to be held in trust or escrow or any other form of asset segregation for the Member or for any other person or persons to whom benefits are to be paid pursuant to the terms of this plan, the Member's only interest hereunder being the right to receive the benefits set forth herein. To the extent any person acquires a right to receive benefits under this Plan, such right shall be no greater than the right of any unsecured general creditor of the Employer.

        9.6    Indemnification.    To the extent permitted by law, the Employer shall indemnify each member of the Board of Directors and any other employee of the Employer to whom duties are assigned with respect to this Plan, against expenses (including any amount paid in settlement) reasonably incurred by him/her in connection with any claims against him/her by reason of his/her conduct in the performance of his/her duties under the Plan, except in relation to matters as to which he/she acted fraudulently or in bad faith in the performance of such duties. This right of indemnification shall be in addition to any other right to which the Board or other person may be entitled as a matter of law or otherwise, and shall pass to the estate of a deceased person.

        9.7    Reports and Records.    The Plan Administrator and those to whom the Plan Administrator has delegated duties under the Plan shall keep records of all their proceedings and actions and shall maintain books of account, records, and other data as shall be necessary for the proper administration of the Plan and for compliance with applicable law.

        9.8    Finances.    The costs of the Plan shall be borne by the Employer. The rights of the Member (or of his Beneficiary) to benefits under the Plan shall be solely those of an unsecured general creditor of the Employer. Any assets acquired by or held by the Employer or set aside in a trust set up by the Employer shall not be deemed to be held as security for the performance of the obligations of the Employer under this Plan. Notwithstanding the foregoing, to the extent under the terms of a trust set up by the Employer payments are made by the Trustee of said Trust to the Member with respect to benefits under this Plan, such payments shall satisfy the obligations of the Employer hereunder to the extent of the payments made.

        9.9    Nonguarantee of Employment.    Nothing contained in this Plan shall be construed as a contract of employment between the Employer and any Member, or as a right of any Member to be continued in employment of the Employer, or as a limitation on the right of the Employer to discharge any of its employees, with or without cause.

        9.10    Applicable Law.    All questions pertaining to the construction, validity and effect of the Plan shall be determined in accordance with the laws of the United States and to the extent not pre-empted by such laws, by the laws of the State of Utah.

        9.11    Headings.    The headings of Sections and Articles in this Plan are for convenience purposes only and shall in no way control or be used in the interpretation of the content of the Sections or Articles or this Plan as a whole.

10



        9.12    Number and Gender.    Where the context requires, the singular shall include the plural and the plural shall include the singular, and any gender shall include both other genders.


ARTICLE X

TRANSFER OF EMPLOYEES AMONG AFFILIATED COMPANIES

        The transfer of a Member from employment with the Employer to employment with an Affiliate shall not be deemed a termination of employment under this Plan. If the Affiliate is an Employer under this Plan, that Employer shall determine whether the Member shall continue to participate in this Plan as an employee of that Employer. Each Employer shall maintain the accounts or benefit for the Member that relates to the benefits earned as an employee of that Employer (based upon the manner in which the benefits under the underlying qualified plan to which the account or benefit relates are attributed among the employers as determined in its discretion by the Plan Administrator of this Plan); provided however, the Employers may agree among themselves to transfer the obligations among themselves so that the benefits under the Plan are paid through a single Employer.

        To the extent a succeeding Employer permits Employee to participate in this Plan, such Employer shall determine the extent to which the prior elections made by the Member shall continue to apply to the Member. In the event the Member is transferred to an Affiliate that does not participate in this Plan, the Member shall cease to participate in this Plan but the former Employer shall continue to maintain the accounts and benefits of the Member earned under this Plan until the benefits become payable to the Member hereunder.
