RECITALS

A. Union Bank of California has established the Union Bank of California SELECTBENEFIT Prototype Defined Contribution Plan (the "Plan") for the benefit of adopting Employers. The Plan is a master prototype plan intended as a qualified retirement plan under Internal Revenue Code Sections 401 and 501, and similar provisions of applicable state law. The Plan is intended to comply with the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) as amended from time to time.

B. The Plan provides for contributions by adopting Employers and Participants to be held in trust, invested, and paid out by the Trustee to or for the benefit of Participants and their Beneficiaries or representatives for the accomplishment of the purposes of said Plan.

C. The Prototype Sponsor desires to provide a trust pursuant to the Plan which is intended to be a tax exempt trust under Section 501 of the Internal Revenue Code and regulations issued pursuant thereto (the "Code"), and under similar provisions of the California Revenue and Taxation Code and any other applicable state law.

AGREEMENT

NOW, THEREFORE, the Prototype Sponsor hereby adopts this Trust Agreement as hereinafter set forth, and the Trustee agrees to receive and hold any and all cash and property which has been or may be paid or delivered to it as Trustee hereunder from time to time in trust for the uses and purposes and upon the terms and conditions hereinafter stated.

ARTICLE 1

TRUST FUND

1.1 Signing Authority; Trustee's Reliance. The Employer's President or other duly authorized officer shall certify in writing to the Trustee the names and specimen signatures of the Administrator, and the Employer or Administrator shall notify the Trustee in writing of all those who are authorized to act as or on behalf of the Employer or Administrator (collectively, "Authorized Representative") and give the Trustee their names and specimen signatures, which shall be updated as necessary by the Employer or Administrator. The Employer or Administrator shall promptly notify the Trustee if any person so designated is no longer authorized to act on behalf of the Employer or Administrator. Until the Trustee receives written notice that a person is no longer authorized to act on behalf of the Employer or Administrator, the Trustee may continue to rely on the Employer's or Administrator's designation of the identity and authority of such person, and any directions given by such Authorized Representative.

1.2 Acceptance of Assets. All contributions or transfers shall be received by the Trustee in cash or in any other property administratively acceptable to the Trustee. The Trust shall consist of the contributions and transfers received by the Trustee, together with the income and earnings from them and any increments to them. The Trustee shall administer the Trust without distinction between principal and income. The Trustee shall have no duty to compute any amount to be transferred or paid

to it by the Employer and it shall not be responsible for the collection of any contributions or transfers to the Trust. Nor shall the Trustee have any duty to see that the contributions received comply with the provisions of the Plan, or to see that funds deposited with it are deposited in accordance with the provisions of the Plan.

1.3 Funding Policy. The Administrator shall have the responsibility for establishing and carrying out a funding policy and method, as specified in Section 402(b)(1) of ERISA, consistent with the objectives of the Plan and the requirements of ERISA, taking into consideration the Plan's short-term and long-term financial needs. The Administrator shall assure that sufficient liquidity shall be maintained to meet the reasonably anticipated requirements of the Trust Fund for payment of expenses of administration, investment and management, and for distribution of benefits to Participants and Beneficiaries.

The funding and investment policies established by the Administrator may be modified at any time by the Administrator, who shall furnish written notice of any such changes affecting the operation of the Trust to the Trustee.

ARTICLE II

INVESTMENTS

2.1 Administrator Authority. Except as provided below, the Administrator shall have all power over, and responsibility for, the management, disposition, and investment of the Trust Assets, and the Trustee shall comply with proper directions (whether transmitted in writing, electronically, via teletransmission, digitally, or in any other form acceptable to Trustee) of the Administrator concerning those assets. The Administrator shall not issue directions in violation of the terms of the Plan and Trust or prohibited by the fiduciary responsibility rules of ERISA. Except to any extent required by ERISA, or otherwise provided in this Trust Agreement, the Trustee shall have no duty or responsibility to review, initiate action, or make recommendations regarding Trust Assets and shall retain all such assets until directed in writing by the Administrator to dispose of them.

2.2 Participant Direction Within Employer Selected Investment Options. In the case of Plans that allow for Participant or Beneficiary direction of investments among investment alternatives and their underlying investment vehicles chosen by the Employer or the Administrator ("Investment Options"), the Participant or Beneficiary shall have full investment authority over the investment of assets allocated to such Participant's account (the "Participant Directed Account" or "Account") in that the Participant or Beneficiary shall select among the investment Options. If the Plan so provides, such Participant Directed Accounts are intended to qualify as ERISA Section 404(c) accounts. To the extent allowed under the Internal Revenue Code, ERISA and applicable regulations thereunder, neither the Employer, the Administrator nor the Trustee shall have any responsibility for monitoring the directions of the Participant or Beneficiary, nor shall they be liable in any manner for investment or other losses or have any other liability for following the directions of the Participant or Beneficiary or any agent designated by them.

The Administrator shall establish uniform and nondiscriminatory rules for the operation of Participant Directed Accounts. Participant Directed Accounts shall be subject to the provisions of the Plan. As provided under ERISA Section 404(c), the Trustee shall not be liable for any loss, or by reason of any breach, which results from such Participant's or Beneficiary's exercise of control. In the absence of directions from a Participant or Beneficiary, the Administrator shall direct the investment of the Participant Directed Account. The Trustee shall have no duty or responsibility to review or make recommendations regarding investments made at the direction of the Participant, Beneficiary, Administrator or Employer. The Trustee may refuse to comply with any directions which the Trustee deems to be improper or contrary to the provisions of the Trust, ERISA or the Code and shall have no liability for such refusal.

2.3 Participant Individually Directed Accounts ("IDAs"). In the case of plans allowing for Participant direction of earmarked accounts, and upon approval of the Administrator, which shall be made in a nondiscriminatory manner, each Participant or Beneficiary shall have the right to direct the investment of all or part of his or her individual account balance. The Participant and the Administrator shall notify the Trustee in writing of such intent and said notice shall state the portion of the Participant's account that he or she desires to be so directed (the "Individually Directed Account" or "XXX"). The Administrator and/or the Trustee shall have the right to refuse to make any investment which, in their opinion, could disqualify the Plan, cause the income of the Trust to be subject to tax, result in a prohibited transaction as defined in ERISA or section 4975(c) of the Code, or is not administratively acceptable to the Administrator and the Trustee. In such case, neither the Administrator nor the Trustee shall be responsible or liable for any loss or expense that may result from such refusal or failure to comply with any direction from the Participant.

As provided under ERISA Section 404(c), neither the Trustee nor any other fiduciary shall be liable for any loss, or by reason of any breach, which results from such Participant's or Beneficiary's exercise of control. In the absence of directions from a Participant or Beneficiary, the Administrator may direct the Investment of the Individually Directed Account. The Trustee shall have no duty or responsibility to review or make recommendations regarding investments made at the direction of the Administrator, Participant or Beneficiary. Any fees, costs, expenses or taxes directly attributable to any Individually Directed Account shall be charged by the Trustee on a reasonable basis directly to such Individually Directed Account, unless otherwise paid by the Employer. The Administrator may terminate any Participant's right to direct the investment of his or her Account, if such direction, in the Administrator's sole discretion, is not in the interest of the Plan or may result in administrative burden to the Administrator or the Trustee.

The Participant or Beneficiary, as applicable, shall be authorized to appoint a broker, agent or investment manager as defined in Section 3(38) of ERISA ("Agent") to whom the Participant or Beneficiary delegates his or her authority to direct the Trustee with respect to investments in the Participant's or Beneficiary's Individually Directed Account. Upon receipt of the Participant's or Beneficiary's designation of such Agent, Trustee shall comply with the Agent's investment directions for the Participant's or Beneficiary's XXX as though they were the Participant's or the Beneficiary's directions, and shall have no liability for following such Agent's directions. The Agent's authority to direct the Participant's or Beneficiary's XXX shall continue until the Participant or Beneficiary gives written notice to the Agent and the Trustee that the Agent's appointment has been revoked.

2.4 Independent Investment Manager. The Employer or Administrator may appoint one or more Investment Managers as defined in Section 3(38) of ERISA to direct the Trustee in the investment of all or a specified portion of the assets of the Trust Fund. The Administrator may also remove any Investment Manager. The Administrator shall promptly notify the Trustee in writing of the appointment or removal of any Investment Manager.

The Administrator shall cause the Investment Manager to acknowledge to the Trustee in writing that the Investment Manager is a fiduciary with respect to the Plan and Trust. If the foregoing conditions are met, the Investment Manager shall have the power to manage, acquire, retain, or dispose of any Trust Assets subject to the Investment Manager's management and direction. The Trustee shall not be liable for the acts or omissions of such Investment Manager, or be under an obligation to review the investments of, or to invest or otherwise manage any asset of the Trust that is subject to the management and direction of such Investment Manager. The Investment Manager shall only make directions which are in compliance with the applicable provisions of ERISA and any regulations or rulings issued thereunder.

2.5 Trustee Investment Authority. The Administrator may also delegate its investment authority to the Trustee for all or part of the Trust. Such delegation must be in writing and delivered to the Trustee.

Upon acceptance of such delegation, the Trustee shall have full power and authority to invest and reinvest the portion of the Trust so designated by the Administrator in investments of any kind permitted under this Trust Agreement.

The Administrator is responsible for providing the Trustee with the funding policy and investment guidelines for the Trust, and the Trustee's responsibility for investment of the assets in the portion of the Trust for which Trustee has investment discretion shall be subject to, and is limited by, the funding policy and investment guidelines issued to it by the Administrator, and by the fiduciary standards of ERISA.

The Trustee shall be responsible for proper diversification of the Trust only if all of the Plan's assets are subject to the Trustee's management. The Administrator, and not the Trustee, shall be responsible for the funding policy, for overall diversification of Plan assets, and for overall compliance of the Trust with statutory limitations on the amount of the Trust's investment in securities or real property of the Employer or its affiliated companies ("Employer Securities" or "Employer Real Property", as those terms are defined in ERISA Section 407).

2.6 Employer Securities. Except as authorized pursuant to Sections 2.2, 2.3 and 2.4, the Administrator shall have sole responsibility and liability for the investment in, and management and disposition of, Employer Securities (as that term is defined in Section 409(l) of the Code). Notwithstanding the previous sentence, if the Employer Securities are thinly traded or not publicly traded on an established exchange, than the Administrator shall have sole responsibility to provide valuations of such Employer Securities.

(a) The Directing Party may direct investment of up to the entire amount of the Trust Assets over which Directing Party has investment authority into Employer Securities if permitted by law. The Directing Party shall not authorize or direct the investment of Trust Assets in Employer Securities unless the Administrator is satisfied that the Employer Securities are exempt from registration under the Federal Securities Act of 1933, as amended, and are exempt from qualification under the California Corporate Securities Law of 1988, as amended, and of any other applicable blue sky law, or in the alternative that the Employer Securities have been so registered and/or qualified. The Administrator shall also specify what restrictive legend on transfer, if any, is required to be set forth on the certificates for the Employer Securities and the procedure to be followed by the Trustee to effectuate a resale of such Employer Securities. The Directing Party shall not direct the investment in "Employer Securities" as that term is used in ERISA, if such investment would be prohibited by ERISA. The Directing Party shall only direct the investment of funds into Employer Securities if (i) those securities are traded on an exchange permitting a readily ascertainable fair market value, or (ii) the Administrator shall have obtained a current valuation by an independent appraiser, and periodically (but no less frequently than annually) supplies updated independent valuations while the Employer Securities remain in the Trust. In determining the value of Employer Securities not traded on an exchange on a periodic basis, the Trustee may conclusively rely on the independent appraisal or other form of valuation acceptable to the Trustee and submitted to it by the Administrator.

(b) For any portion of the Trust Fund which consists of Employer Securities, the voting or proxy or other rights with respect to such Employer Securities shall be passed through to Participants as provided in this section. With respect to Employer Securities that are allocated to Participants' accounts, each Participant shall be entitled to direct the Trustee as to the manner in which such Employer Securities then allocated to his or her account(s) will be voted as to the items specified in Code Section 409(e)(2) or 409(e)(3), as the case may be. Such directions may be achieved through the use of proxy or similar statements delivered to the Participants with respect to the Employer Securities allocated to their accounts. The Administrator shall provide any information requested by the Trustee that is necessary or convenient in connection with obtaining

and preserving the confidentiality of the Participants' directions. Any allocated Employer Securities with respect to which Participants are entitled to issue directions pursuant to the foregoing and for which directions are not received by the Trustee shall be voted in the same proportion as the shares of Employer Securities for which voting directions have been received, unless the Trustee is required by law to exercise its discretion in voting such shares. Any allocated Employer Securities with respect to which Participants are not entitled to issue directions pursuant to the foregoing, and all unallocated Employer Securities, shall be voted by the Trustee in the same proportion as the shares for which voting directions have been received, unless the Trustee is required by law to exercise its discretion in voting such shares. In the event that no voting rights for the Employer Securities are required by law or the terms of the Plan to be passed through to Participants, the Employer Securities shall be voted by the Trustee as instructed by the Administrator.

(c) In response to a tender offer, the Trustee shall tender only those allocated shares for which the Directing Parties' directions to tender have been received; any allocated but unvoted shares shall not be tendered. Any unallocated shares shall be retained or tendered in accordance with instructions from the Administrator, to the extent permitted by law.

(d) The Employer or Administrator shall ensure that Participants receive at least as much information regarding the proxy or tender offer matters as is sent to shareholders. The Trustee shall have no duty to provide Participants with information necessary to make an informed decision with respect to the voting or tendering of Employer Securities, which shall be the exclusive duty of the Employer or Administrator.

(e) The Employer shall indemnify and hold harmless the Trustee with respect to (i) any claim, demand or loss in connection with making Employer Securities available as Investment Options, and (ii) any action taken or not taken with regard to voting or tendering Employer Securities except for losses resulting from the Trustee's negligence or willful misconduct, because the Trustee shall have no discretion with respect to such action unless required by law.

(f) The Trustee shall not be liable under the Plan or the Trust for any purchase or sale of, or investment in or retention of, Employer Securities held as Trust assets, whether retention is due to (i) instructions to retain, (ii) inability to sell due to any Federal or State securities law restrictions, or (iii) the unmarketable or illiquid nature of the investment.

2.7 Employer Real Property. Except as authorized pursuant to Sections 2.3 and 2.4, the Administrator shall have sole responsibility and liability for the investment in, and management and disposition of, Employer Real Property. Notwithstanding the previous sentence, the Administrator shall have sole responsibility to provide valuations of such Employer Real Property.

The Directing Party shall not authorize or direct the investment in "Employer Real Property", as that term is used in ERISA, if such investment would be prohibited by ERISA. The Directing Party shall only authorize or direct the investment of funds into Employer Real Property, if the Administrator has obtained a current valuation by an independent appraiser, and periodically supplies updated valuations while the Employer Real Property remains in the Trust. In determining the value of Employer Real Property on a periodic basis, the Trustee may conclusively rely on the independent appraisal or other form of valuation acceptable to the Trustee and submitted to it by the Administrator.

The Trustee shall not be liable under the Plan or the Trust for any investment in, or retention or disposition of, Employer Real Property held as Trust assets, whether retention is due to (i) instructions to retain, (ii) inability to sell due to any restrictions, or (iii) the unmarketable or illiquid nature of the investment.

2.8 Insurance Products. The Directing Party may direct the Trustee in writing to invest assets of the Trust in insurance products of all kinds authorized under the Plan, including but not limited to: group or individual insurance contracts, annuity contracts, and guaranteed investment contracts,

provided however that such contracts are issued by an insurance company or companies qualified to do business in more than one state. The Directing Party shall have the sole responsibility for and shall direct the Trustee with respect to such insurance products. The investment in, valuation of, and management and disposition of these insurance products shall be the sole responsibility of the Directing Party, and the Trustee shall follow their directions with respect to such insurance products and shall have no liability therefore.

2.9 Participant Loans. Where loans are made to Plan Participants or Beneficiaries ("Participant Loans"), all fiduciary duties and responsibilities for administration of the Trust with respect to any Participant Loans shall rest with the Administrator or a named fiduciary which shall be appointed by the Administrator (the "Loan Fiduciary"). These duties shall include but not be limited to the review and acceptance or rejection of loan applications, making of the Participant Loans, determination of allowable Participant Loan amount, the determination of any grace period for delinquent loans in accordance with regulations, after which Trustee shall declare default and issue tax reports, and determination of when to foreclose on collateral securing defaulted loans. Additionally, the Loan Fiduciary shall establish the interest rate to be charged for the Participant Loan, the maturity date of the loan, the amount which may be loaned, and the amount of the affected vested account balance which may secure the Participant Loan under applicable laws and regulations. In the absence of a formal appointment of a Loan Fiduciary, the Administrator shall be the Plan's Loan Fiduciary. All loan documents shall be prepared by Trustee upon written direction of the Loan Fiduciary unless otherwise agreed to by Trustee.

2.10 Participant Loans—Omnibus Loan Asset. If the Administrator directs the Trustee to hold the participant loan portfolio as an omnibus asset of the Trust (the "Omnibus Loan Asset"), the Loan Fiduciary, or the loan administrator appointed by the Administrator ("Loan Administrator"), shall direct and administer loans made to Participants or Beneficiaries pursuant to the Plan.

(a) The Loan Administrator, or the Loan Fiduciary, shall have responsibility for such loans including, without limitation, responsibility for the following: the development of procedures and documentation for Participant loans; the acceptance of loan applications, the preparation and execution of loan documentation; the disclosure of interest rate information as required by Regulation Z of the Federal Reserve Board promulgated pursuant to the Truth in Lending Act (15 U. S. C. §1801 et. seq.); the enforcement of promissory note terms, including, but not limited to, directing the Trustee to take specified actions, including to fund loans and receive loan payments; and the maintenance of accounts and records regarding interest and principal payments on notes. The Trustee shall not be responsible for reviewing such documents, records and procedures, but the Trustee may, from time to time, examine such documents, records and procedures as it deems appropriate.

(b) The Loan Fiduciary or Loan Administrator, as applicable, shall collect loan payments from Participants and Beneficiaries, and shall forward a net amount to the Trustee, with a statement directing allocation of receipts on a monthly basis. The Loan Fiduciary or Loan Administrator shall render an accounting to the Administrator, on a monthly or quarterly basis, which shall set forth the Participants' loan balances for each Participant loan and in the aggregate all investments, principal and income receipts, disbursements and other transactions effected by it with respect to the Participant loans during the accounting period since the last report to the Administrator, and shall provide a fair market valuation of the Omnibus Loan Asset to the Trustee no less frequently than quarterly. The Trustee may rely on such valuation prepared and submitted by the Loan Fiduciary or Loan Administrator in valuing Trust Assets as required by this Trust Agreement and shall be under no liability for the Trust Assets administered by the Loan Fiduciary, or for accounting for Participant loans or transactions relating to Participant loans in accordance with the Loan Fiduciary's accounting and reports.

(c) The Trustee shall account for Participant loans in the aggregate, as a single asset of the Trust, identified as the Omnibus Loan Asset. Within thirty (30) days of the close of each fiscal year of the Trust, and within thirty (30) days of the termination of this Trust Agreement, the Loan Fiduciary or Loan Administrator shall file with the Administrator a written accounting setting forth in the aggregate all investments, receipts, disbursements and other transactions effected by the Loan Fiduciary or Loan Administrator with respect to Participant loans during such fiscal year or the period from the close of the last fiscal year to the date of such termination, and the Loan Fiduciary or Loan Administrator shall provide the Trustee with a fair market valuation of the Omnibus Loan Asset as of the close of each Plan Year. The Trustee may rely on such fair market valuation provided by the Loan Fiduciary or Loan Administrator in valuing and accounting for Trust Assets as required by this Trust Agreement and shall be under no liability for accounting for Participant loans.

(d) The Administrator shall direct the Trustee with respect to all returns and filings required by the Internal Revenue Code and regulations, or applicable State law, as a result of any Participant loan, including, but not limited to, returns and filings required by reason of failure by the borrower to make any payments. The Trustee shall be under no liability for failure to file such returns or reports, unless as a result of failure to follow Administrator's direction.

(a) To cause all or any part of the Trust to be held in the name of the Trustee (which in such instance need not disclose its fiduciary capacity) or, as permitted by law, in the name of any nominee, and to acquire for the Trust any investment in bearer form. Trustee may combine certificates representing such investments with certificates of the same issuer that it holds in other fiduciary capacities; or it may deposit or arrange for the deposit of such securities in a qualified central depository even though such securities may then be merged and held in bulk in the name of the nominee of the depository along with other securities deposited by other persons. Additionally, Trustee may deposit or arrange for deposit of any securities issued by the United States government or one of its agencies or instrumentalities in such a depository or with a Federal Reserve Bank.

4.2 Records. The Trustee shall maintain or cause to be maintained suitable records, data and information relating to its functions hereunder. The Trustee shall keep accurate and detailed accounts of all investments, receipts, disbursements and other actions hereunder, except for Omnibus Loan Assets, which shall be reflected as provided in Section 2.10. Its books and records relating thereto shall be open to inspection and audit at all reasonable times by the Employer, the Administrator or their duly authorized representatives.

4.3 Accounts. Periodically, as specified by the Employer, or the Participant in the case of IDAs, and within sixty (60) days after the close of each Plan Year and within sixty days after the resignation of the Trustee as provided in Article VII hereof, the Trustee shall render to the Employer, investment Manager or the Participant in the case of IDAs, a written account showing in reasonable summary the investments, receipts, disbursements and other transactions engaged in by the Trustee during the preceding Plan Year or accounting period with respect to the Trust. Such account shall set forth the assets and liabilities of the Trust, valued as of the end of the accounting period.

The Employer, Investment Manager, or the Participant in the case of XXX, shall have sixty (60) days after the Trustee's mailing of each such account within which to file with the Trustee written objections to such account. Upon the expiration of each such period, the Trustee shall be forever released and discharged from all liability and accountability to the Employer, the Participant and the Trust with respect to the propriety of its acts and transactions shown in such account except with respect to any such acts or transactions as to which a written objection has been filed within such sixty (60) day period with the Trustee.

4.4 Valuation of Special Assets. Notwithstanding anything herein to the contrary, the Trustee shall have no duty or responsibility to obtain valuations of any Trust assets whose value is not readily determinable on an established market. The Employer, Administrator, Investment Manager or directing Participant shall have sole responsibility to supply periodic valuations of such assets to the Trustee in a timely manner. The Employer or the Participant, or the Trust as appropriate, shall bear sole responsibility for the cost of obtaining said valuations. The Trustee may conclusively rely on such valuations provided by the Employer, Investment Manager, Administrator or Participant. If they fail to provide such values, the Trustee may take whatever action it deems reasonable, including employment of attorneys, appraisers or other professionals, the expense of which will be borne by the Trust. Despite the foregoing, all values of unlisted or thinly traded Employer Securities shall be determined by an appraisal by a qualified independent appraiser acceptable to the Trustee, the expense of which will be borne by the Trust or the Employer as appropriate.

4.5 Reports. The Trustee shall file such descriptions and reports and shall furnish such information and make such other publications, disclosures, registrations and other filings as are required of the Trustee by ERISA or other applicable law, except for fillings in connection with Employer Securities, which shall be the sole responsibility of the Employer.

4.6 Directions to Trustee. The Trustee is authorized to act upon proper directions of the Employer, the Administrator, Investment Manager, any other fiduciary, Participant, Beneficiary, Directing Party, and their Authorized Representatives, as applicable, including directions given by photostatic teletransmission using facsimile signature, or those instructions which are digitally recorded on the UBOC Voice Response Unit ("VRU") or internet website. The Trustee is also authorized to act on verbal instructions in its discretion prior to receipt of written or photostatic teletransmission instructions. The Trustee is hereby authorized to record conversations and facsimile transmissions made in connection with the Trust. The Trustee's recording or lack of recording of any such oral, internet or digital instructions, and/or receipt or lack of receipt of directions by facsimile transmissions or otherwise, as reflected in the Trustee's records maintained in the ordinary course of business, shall constitute conclusive proof of the Trustee's receipt or non-receipt of such instructions.

The Trustee shall not be liable for losses attributable to any directions, lack of directions or exercise of control by a party with investment discretion over the Trust or any part thereof. Likewise, the Trustee shall have no duty or responsibility to review or make recommendations regarding Investments made at the direction of any party with investment discretion over the Trust or any portion thereof.

4.7 Authorized Representative. The Employer or the Administrator shall inform the Trustee immediately in writing of the appointment of any Authorized Representative to whom the Employer or the Administrator has given authorization to direct the Trustee with respect to the Trust, any change in tax status, or any other change in circumstances which could affect the Trustee's administration or management of the Trust.

The Trustee may rely on such designations and follow any instructions of such Authorized Representatives, whether verbal, by facsimile or in writing as though they were Employer's, Administrator's, Investment Manager's or Participant's instructions, as applicable, and Trustee's business record entry of any directions by any of them shall be conclusive proof of the giving of such directions.

Any transactions initiated by the Trustee before receiving actual notice of any change with respect to (a) such Authorized Representative(s) or their authority, (b) the termination of the Account, or (c) termination of the fiduciary status of the Employer or Administrator, shall be valid and binding on the Employer or their successors and assigns, and the Trust.

4.8 Wire Transfers. The Trustee shall follow the Employer's or Administrator's wire transfer instructions in compliance with the security procedures promulgated by the Trustee and agreed to by the Employer. The Trustee shall perform a telephonic verification to Employer or Employer's Authorized Representative or such other security procedure, as Trustee may require, prior to wiring funds or following facsimile directions. The Employer assumes all risk of delay of transfer if the Trustee is unable to reach the Employer or the Employer's Authorized Representative, or in the event of delay as a result of attempts to comply with any security procedure selected by the Employer.

ARTICLE V

RESTRICTIONS ON DISTRIBUTION

5.1 Persons to Receive Payment.

(a) The Trustee shall, except as otherwise provided below, pay all amounts payable hereunder only to, or for the benefit of, the person or persons designated under the Plan or deposit to the Participant's or Beneficiary's checking or savings account or individual Retirement Account as directed by the Administrator and not to any other person or corporation, and only to the extent of assets held in the Trust for the benefit of the Participant. The Administrator's instructions to the

Trustee to make distributions or not to make distributions, and the amount thereof, shall be conclusive on all parties, including but not limited to Participants and Beneficiaries.

(b) In the event any controversy shall arise as to the person or persons to whom any distribution or payment is to be made by the Trustee, or as to any other matter arising in the administration of the Plan or Trust, the Trustee may retain the amount in controversy pending resolution of the controversy or the Trustee may file an action seeking declaratory relief and/or may interplead the Trust Assets or funds in issue, and name as necessary parties the Employer and/or any or all persons making conflicting demands.

(c) Whether a distribution or payment check has been issued or not, the Trustee shall not be liable for the payment of any interest or income on any amount paid or withheld or interpleaded under subsection (b).

Notwithstanding the, foregoing, the Employer may agree to allow Participants and Beneficiaries to borrow from the Plan, and to secure their loans with their vested Account balances, to the extent provided under the Plan and this Trust Agreement.

5.3 Qualified Domestic Relations Orders. The preceding section shall also apply to the creation, assignment, or recognition of a right to any benefit payable with respect to a Participant pursuant to a domestic relations order, unless such an order is determined by the Administrator to be Qualified Domestic Relations Order, as defined in ERISA and in Section 414 (p) of the Code. Any domestic relations order entered before January 1, 1985 will be treated as a Qualified Domestic Relations Order if payment of benefits has commenced as of such date, and may be treated as a Qualified Domestic Relations Order if payment of benefits had not commenced as of such date, even though the order does not satisfy the requirements of Section 414(p). The Administrator shall direct the Trustee, in writing, as to the disposition of any domestic relations order and shall direct the Trustee as to any distributions necessary pursuant to any order determined by the Administrator to be a Qualified Domestic Relations Order.

The Employer may remove the Trustee upon thirty (30) days' prior written notice to the Trustee, which notice may be waived by the Trustee. However, notwithstanding the foregoing or any other provision of the Plan or this Trust Agreement to the contrary, the Trustee shall have an unrestricted right of Immediate resignation effective upon thirty (30) days' prior written notice to the Employer with respect to any portion of the Trust Assets consisting of Employer Securities or Employer Real Property, at which time the Employer's President and Chief Financial Officer shall be treated as having appointed themselves Trustees and as having filed their acceptance of appointment with the Trustee and shall automatically become the Successor Co-Trustees until a new successor Trustee is appointed by them.

6.2 Designation of Successor Trustee. Upon notice of Trustee's resignation or removal, Employer shall promptly designate a Successor Trustee who will accept transfer of the assets of the Trust.

and shall be treated as having filed their acceptance of appointment with the former Trustee and shall automatically become the Successor Co-Trustees until a new Successor Trustee is appointed.

6.3 Court Appointment of Successor. If the Employer does not designate a Successor Trustee, or if a Successor Trustee designated by the Employer has not accepted its appointment, within thirty (30) days after the Trustee gives notice of its resignation or receives notice of removal, the Trustee may, at the expense of the Trust, apply to a court of competent jurisdiction to appoint a Successor Trustee. Until a Successor Trustee is appointed, the Trustee shall be entitled to be compensated for its services according to its published fee schedule then in effect for acting as Trustee in accordance with the Plan and Trust.

6.4 Successor's Powers. A Successor Trustee shall have the same powers and duties as those conferred upon the original Trustee hereunder. A resigning Trustee shall transfer the Trust Assets and shall deliver the books, accounts and records of the Trust to the Successor Trustee as soon as practicable. The resigning Trustee is authorized, however, to reserve such amount as may be necessary for the payment of its fees and expenses incurred prior to its resignation or removal, and the Trust Assets shall remain liable to reimburse the resigning or removed Trustee for any costs, expenses or attorneys' fees or losses incurred, whether before or after resignation or removal, due solely to Trustee's holding title to and administration of Trust Assets.

LIABILITIES

8.1 Declaration of Intent. In keeping with the public policy expressed in Section 410(a) of ERISA, nothing in this Article purports to relieve a fiduciary from liability for any responsibility, obligation or duty under Part 4 of Title I of ERISA. However, to the full extent permitted in Section 405 of ERISA and otherwise as not prohibited by law, it is the intent of this Article to relieve each fiduciary from all liability for any acts or omissions of any other fiduciary or any other person and to declare the absence of liabilities of all persons referred to in this Article to the extent not imposed by law or by provisions of this Trust Agreement. Each of the following Sections, in declaring such limitations, is set forth without limiting the generality of this Section but in each case shall be subject to the provisions, limitations and policies set forth in this Section. Additionally, to the full extent

permitted in ERISA Section 404(c), no fiduciary shall be liable for any investment selection, investment loss or by reason of any breach of fiduciary duty of breach of this Agreement which results from Participant's or Beneficiary's exercise of control over the assets of his or her Accounts or XXX.

8.2 General Limitations of Liability

(a) No fiduciary shall be liable with respect to a breach of fiduciary duty under Title I of ERISA if such breach was committed before he, she or it became a fiduciary or after he, she or it ceased to be a fiduciary.

8.3 Liability of the Trustee.

(a) The Trustee shall have no powers, duties or responsibilities with regard to the administration of the Plan or to determine the rights or benefits of any person having or claiming an Interest under the Plan or in the Trust or under this Trust Agreement or to control any disposition of the trust or part thereof which is directed by the Administrator.

(b) The Trustee shall have no liability for the adequacy or timeliness of contributions for the purposes of the Plan or for enforcement of the payment thereof.

(e) During such period or periods of time, if any, as a Directing Party is directing the investment and management of Trust Assets, the Trustee shall have no obligation to determine the existence of any conversion, redemption, exchange, subscription or other right relating to securities purchased on the directions of a Directing Party, if notice of any such right was given prior to the purchase of such securities. If such notice is received by the Trustee after the purchase of such securities, the Trustee shall notify the Directing Party. The Trustee shall have no obligation to exercise any such right unless it is informed of the existence of the right and is instructed to exercise such right, in writing, by the Directing Party within a reasonable time prior to the expiration of such right.

(f) If a Directing Party directs the Trustee to purchase securities issued by any foreign government or agency thereof, or by any corporation domiciled outside of the United States, it shall be the responsibility of such Directing Party to advise the Trustee in writing with respect to any laws or regulations of any foreign countries or any United States territories or possessions which shall apply, in any manner whatsoever, to such securities, including, but not limited to, receipt of dividends or interest or reclamation of foreign taxes by the Trustee for such securities. If the Trustee is directed not to reclaim foreign taxes, the Trustee shall have no responsibility to reclaim any such taxes. Any expenses, costs or extraordinary fees incurred by the Trustee for the reclamation of foreign taxes shall be charged to the Trust.

(a) The Trustee shall not be liable for, and the Employer agrees to indemnify and hold harmless the Trustee, its officers, directors, employees and agents from and against any loss, or liability, claims, demands, damages and expenses, (including reasonable attorneys' fees and costs

incurred by the Trustee), any claims of breach of fiduciary duty brought by any person or entity, lawsuits, disputes of any kind, and any taxes or penalties incurred by the Trustee, which may arise from (i) any acts taken in accordance with directions (or any failure to act in the absence of such directions) from the Administrator, Employer, Investment Manager, Authorized Representative, Participant, Beneficiary, Loan Fiduciary or any other person designated to act on their behalf which the Trustee reasonably believes to have been given by them; (ii) the negligence or willful misconduct of the Administrator, Employer, Investment Manager, Participant, Beneficiary, Authorized Representative, Loan Fiduciary or any other person designated to act on their behalf, or (iii) any act or omission by the Employer, Administrator, Investment Manager, Participant, Beneficiary, Authorized Representative, Loan Fiduciary or any other person designated to act on their behalf which results in loss to the Trust, except in the event of the Trustee's negligence or material breach of this Agreement which directly relates to and causes the loss to the Trust.

The Trust, and not the Trustee, shall be responsible for payment of any expenses of clearing any hazardous substances found in connection with the property held as an Asset of the Trust, to the extent not paid by other responsible parties. This section will survive the sale or other disposition of any real estate investment of the Trust Fund and the termination of this Agreement.

ARTICLE IX

DURATION AND TERMINATION

9.1 Irrevocability. This Trust is hereby declared to be irrevocable, except with respect to Section 9.2 below. It is intended that this Trust shall be tax-exempt and that the Plan and Trust shall qualify under Sections 401(a) and 501(a) of the Code. However, notwithstanding any other provisions of the Trust, if the Internal Revenue Service is requested to issue to the Employer a favorable written determination or ruling with respect to the initial qualification of the Plan and exemption of the Trust from tax and such request is denied, the Trustee shall, after receiving a written direction from the

Administrator, pay to each Participant that portion of the Trust applicable to said Participant's voluntary contributions, if any, and provided the Plan so states, pay to the Employer any part of the Trust attributable to Employer contributions then remaining in the Trustee's possession, provided, however, that all distributions shall be adjusted for any investment losses and Trustee's fees and costs incurred to date. As a condition to such repayment, the Employer agrees to indemnify, defend and hold the Trustee harmless from all claims, including claims of breach of fiduciary duty, actions, demands, or liabilities and attorney fees and costs arising in connection with such repayment.

9.2 Termination. This Trust may be terminated at any time by the Employer. Upon such termination, the Trust assets shall be distributed by the Trustee as and when directed by the Administrator in accordance with the provisions of this Trust Agreement and the Plan document. From the date of termination of the Plan and until the final distribution of the Trust, the Trustee shall continue to have all powers provided under this Trust that are necessary or desirable for the orderly liquidation and distribution of the Trust. In no instance, upon any termination and subsequent distribution, shall the Trust or any part of it be used for, or diverted to, purposes other than for the exclusive benefit of Participants, their Beneficiaries, and for defraying the administrative expenses of the Plan and Trust until all Plan liabilities have been satisfied, except in the instance of the failure of the Trust initially to qualify for tax-exempt status as set forth in Section 9.1.

Upon termination of the Plan, the Trust Fund shall be distributed as directed by the Administrator; provided, however, that the Trustee shall not be required to make any distribution prior to receipt of a determination letter from the Internal Revenue Service that the termination does not adversely affect the tax-exempt status of the Plan and Trust. In the event the Administrator requests distribution of the Trust assets (a) without receipt of a favorable determination letter on Plan termination, or (b) upon failure to receive a favorable determination on initial qualification, the Employer shall indemnify and hold the Trustee harmless against all claims, liability, costs and fees, including but not limited to any attorneys' fees and costs, any taxes or penalties, and any claims of breach of fiduciary duty brought by any person or entity.

9.3 Duration. This Trust shall continue in full force and effect for the maximum period of time permitted by law, unless this Trust is sooner terminated in accordance with the Plan, the Code and ERISA.

(b) if an Employer's contribution or payment is conditioned on initial qualification of the plan under Section 401 of the Code, and if the plan receives an adverse determination with respect to its initial qualification, then this section shall not prohibit the return of such contribution to the Employer, as contemplated by Section 403 of ERISA; and

(c) if an Employer's contribution or payment is conditioned upon the deductibility of such amount under Section 404 of the Code, then, to the extent the deduction is disallowed, this section shall not prohibit the return of such contribution to the Employer (to the extent disallowed) within one year after such determination of disallowance of the deduction.
