In addition to making contributions, the Employer, through the Committee, shall furnish the Trustee with such information and data relative to the Plan as is necessary for the proper administration of the Trust.

For purposes of this Agreement, the appointment of an Investment Manager pursuant to this Section 3.3 shall become effective as of the effective date specified in such notice, or, if later, as of the date on which the Trustee receives proper notice of such appointment.

The Committee shall give written notice to the Trustee of the resignation or removal of an Investment Manager previously appointed pursuant to this Section 3.3. From and after the date on which the Trustee receives such notice, or, if later, the effective date of the resignation or removal specified in such notice, the Committee shall be responsible, in accordance with Section 3.4, for the investment and reinvestment of the portion of the Trust previously managed by such Investment Manager, until such time as a successor Investment Manager has been duly appointed pursuant to this Section 3.3.

The Trustee may rely and act upon any certificate, notice or direction of the Investment Manager which the Trustee believes to be genuine and to have been signed by the Investment Manager.

The Trustee shall be under no duty or obligation to review any investment to be acquired, held or disposed of pursuant to such directions nor to make any recommendation with respect to the disposition or continued retention of any such investment. The Trustee shall have no liability or responsibility for its action or inaction pursuant to the direction of, or its failure to act in the absence of directions from, the Committee or an Investment Manager, except to the extent provided in Section 5.1.

The Committee or an Investment Manager appointed pursuant to Section 3.3 may, at any time and from time to time, issue orders for the purchase or sale of securities directly to a broker; and in order to facilitate such transaction, the Trustee upon request shall execute and deliver appropriate trading authorizations. Written notification of the issuance of each such order shall be given promptly to the Trustee by the Committee or the Investment Manager, and the execution of each such order shall be confirmed by written advice to the Trustee by the broker. Such notification shall be authority for the Trustee to pay for securities purchased against receipt thereof and to deliver securities sold against payment therefor, as the case may be.

To the extent that neither the Committee nor an Investment Manager furnishes directions as to the investment of the Trust, the Trustee shall invest and reinvest the Trust in any stable-value investment currently available to the Trust. If no stable-value investment is currently available to the Trust, the Trustee shall invest and reinvest the portion of the Trust subject to this section 3.4(c) in an investment generally recognized as having the lowest investment risk of all investments available to the Trust.

Investment in Short-Term Obligation. Notwithstanding any provisions of this Section 3 to the contrary, the Trustee or its designee, upon the direction of the Committee, may retain uninvested cash or cash balances, without being required to pay interest thereon.

Substitution of Assets. The Employer shall have the right at any time, and from time to time, in its sole discretion, to substitute assets of equal fair market value for any asset held by the Trust. This right is exercisable by the Employer in a nonfiduciary capacity without the approval or consent of any person in a fiduciary capacity.

Trust Income. During the term of this Trust, all income received by the Trust, net of expenses and taxes, shall be accumulated and reinvested.

General. The Employer shall deliver to the Trustee a schedule ("Payment Schedule") that indicates the amounts payable in respect of each Plan participant (and his or her beneficiaries), that provides a formula or other instructions acceptable to the Trustee for determining the amounts so payable, the form in which such amount is to be paid (as provided for or available under the Plan), and the time of commencement for payment of such amounts. Except as otherwise provided herein, the Trustee shall make payments to the Plan participants and their beneficiaries in accordance with such Payment Schedule.

Reporting and Withholding Requirements. The Employer or Trustee shall provide for the reporting and withholding of any federal, state or local taxes that may be required to be withheld with respect to the payment of benefits pursuant to the terms of the Plan and shall pay amounts withheld to the appropriate taxing authorities. Upon the occurrence of a distribution pursuant to the Plan, the Committee shall direct the Trustee to send the Employer an amount, as determined by the Employer, sufficient for the Employer to discharge its withholding obligations with respect to the distribution.

A direction by the Committee to make a distribution from the Trust shall:

be made in writing;

specify the amount determined by the Employer to be sufficient for the Employer to discharge its withholding obligation; and

be deemed to certify to the Trustee that such direction and any payment pursuant thereto are authorized under the terms of the Plan.

Payments by Employer. The Employer may make payment of benefits directly to Plan participants or their beneficiaries as they become due under the terms of the Plan. The Employer shall notify the Trustee of its decision to make payment of benefits directly prior to the time amounts are payable to participants or their beneficiaries. In addition, if the principal of the Trust, and any earnings thereon, are not sufficient to make payments of benefits in accordance with the terms of the Plan, the Employer shall make the balance of each such payment as it falls due. The Trustee shall notify the Employer where principal and earnings are not sufficient.

Payments to Employer. Except as expressly provided in the Plan, the Employer shall have no right or power to direct the Trustee to return to the Employer any of the Trust Fund before all payments of benefits have been made pursuant to the Plan. However upon written request and certification from the Employer of the amount required to pay benefits provided under the terms of the Plan, if the Trustee determines that the value of the assets of the Trust Fund are in excess of 100% of the amount required to pay the benefits provided under the terms of the Plan, then such excess assets, including both principal and income, shall be returned to the Employer.

General Standard of Care. The Trustee, the members of the Committee and any Investment Manager shall at all times discharge their duties with respect to the Trust solely in the interest of the Plan participants and their beneficiaries and with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims, provided, however, that the Trustee shall incur no liability to any person for any action taken pursuant to a direction, request or approval given by the Employer which is contemplated by, and in conformity with, the terms of the Plan or this Trust and is given in writing by the Employer. In the event of a dispute between the Employer and a party, the Trustee may apply to a court of competent jurisdiction to resolve the dispute.

No Liability for Acts of Others. No fiduciary under this Agreement shall be liable for an act or omission of another person in carrying out any fiduciary responsibility where such fiduciary responsibility is allocated to such other person by this Agreement or pursuant to a procedure established in this Agreement.

Legal Counsel. The Trustee may consult with legal counsel (who may be counsel to the Employer) concerning any questions which may arise under this Agreement, and the opinions of such counsel shall be full and complete protection with respect to any action taken, or omitted, by the Trustee hereunder in good faith in accordance with the opinion of such counsel.

Liability Under Plan. The duties and obligations of the Trustee shall be limited to those expressly set forth in this Agreement, notwithstanding any reference herein to the Plan. Notwithstanding any other provision of this Trust Agreement, the Trustee and its officers, directors and agents hereunder shall be indemnified and held harmless by the Employer and the Trust to the fullest extent permitted by law against any and all costs, damages, expenses and liabilities including, but not limited to, attorneys’ fees and disbursements reasonably incurred by or imposed upon it in connection with any claim made against it or in which it may be involved by reason of it being,

The Trustee shall keep accurate and detailed accounts of all investments, reinvestments, receipts, disbursements, and all other transactions hereunder, and all such accounts and the books and records relating thereto shall be open to inspection at all reasonable times by the Employer or the Committee or persons designated by them.

Valuation of Trust. The Trustee or its designee shall value or cause to be valued the Trust as of the last business day of each calendar quarter (“Valuation Date”), and shall report to the Committee the value of the Trust as of such date, within a reasonable time after the first day of the month next following each Valuation Date.

Reports to Committee.

Right of Judicial Settlement. The Trustee, the Committee, and the Employer, or any of them, shall have the right to apply at any time to a court of competent jurisdiction for the judicial settlement of the Trustee’s account. In any such case, it shall be necessary to join as parties thereto only the Trustee, the Committee and the Employer; and any judgment or decree which may be entered therein shall be conclusive upon all persons having or claiming to have any interest in the Trust or under the Plan.

Enforcement of Agreement. To protect the Trust from expenses which might otherwise be incurred, the Employer and the Committee shall have authority, either jointly or severally, to enforce this Agreement on behalf of all persons claiming any interest in the Trust or under the Plan, and no other person may institute or maintain any action or proceeding against the Trustee or the Trust in the absence of written authority from the Employer, the Committee or a judgment of a court of competent jurisdiction that in refusing authority the Committee acted fraudulently or in bad faith.

Taxes. Any taxes that may be imposed upon the Trust or the income therefrom shall be deducted from and charged against the Trust.

Compensation of Trustee; Expenses. The Trustee shall receive for its services hereunder such compensation as may be agreed upon in writing from time to time by the Employer and the Trustee and shall be reimbursed for its reasonable expenses, including counsel fees, incurred in the performance of its duties hereunder. The Trustee shall deduct from and charge against the Trust such compensation and all such expenses unless previously paid by the Employer.

Resignation or Removal of Trustee. The Trustee may resign as trustee hereunder at any time by giving sixty (60) days prior written notice to the Employer. The Employer may remove the Trustee as trustee hereunder at any time by giving the Trustee prior written notice of such removal, which shall include notice of the appointment of a successor trustee. Such removal shall take effect not earlier than sixty (60) days following receipt of such notice by the Trustee unless otherwise agreed upon by the Trustee and the Employer.

Appointment of Successor. In the event of the resignation or removal of the Trustee, a successor trustee shall be appointed by the Employer. Except as is otherwise provided in Section 8.1, such appointment shall take effect upon delivery to the Trustee of an instrument so appointing the successor and an instrument of acceptance executed by such successor. If within sixty (60) days after notice of resignation has been given by the Trustee, a successor has not been appointed as provided in Section 8.1, the Trustee may apply to any court of competent jurisdiction for the appointment of such successor or for instructions. All expenses of the Trustee in connection with the preceding shall be allowed as administrative expenses of the Trust.

Upon the appointment of a successor hereunder, the Trustee shall timely transfer and deliver all assets of the Trust to such successor; provided, however, that the Trustee may reserve such sum of money as it shall in its sole and absolute discretion deem advisable for payment of its fees and all expenses including counsel fees in connection with the settlement of its account, and any balance of such reserve remaining after the payment of such charges shall be paid over to the successor trustee. If such reserve shall be insufficient to pay such charges, the Trustee shall be entitled to recover the amount of any deficiency from the Employer, from the Trust, or from both.

Upon the completion of the succession and the rendering of its final accounts, the Trustee shall have no further responsibilities whatsoever under this Agreement.

Successor Bound by Agreement. All the provisions of this Agreement shall apply to any successor trustee with the same force and effect as if such successor had been originally named herein as the trustee hereunder.

Insolvency. The Trustee shall cease payment of benefits to Plan participants and their beneficiaries if the Employer is Insolvent. The Employer shall be considered "Insolvent" for purposes of this Trust Agreement if (i) the Employer is unable to pay its debts as they become due, or (ii) the Employer is subject to a pending proceeding as a debtor under the United States Bankruptcy Code.

General Creditors. At all times during the continuance of this Trust, the principal and income of the Trust shall be subject to claims of general creditors of the Employer.

The Board of Directors and the Chief Executive Officer of Employer shall have the duty to inform the Trustee in writing of Employer’s Insolvency. If a person claiming to be a creditor of the Employer alleges in writing to the Trustee under penalty of perjury that that Employer has become Insolvent, the Trustee shall take action it deems prudent to determine whether Employer is Insolvent, and, pending such determination, the Trustee shall discontinue payment of benefits to Plan participants or their beneficiaries.

Unless the Trustee has actual knowledge of Employer’s Insolvency, or has received notice from Employer or a person claiming to be a creditor alleging that Employer is Insolvent, the Trustee shall have no duty to inquire whether Employer is Insolvent. The Trustee may in all events rely on the determination of the independent accountant regularly auditing the financial records of Employer as to whether Employer is Insolvent.

If at any time the Trustee has made or received a determination that Employer is Insolvent, the Trustee shall discontinue payments to Plan participants or their beneficiaries and shall hold the assets of the Trust for the benefit of Employer’s general creditors. Nothing in this Trust Agreement shall in any way diminish any rights of Plan participants or their beneficiaries to pursue their rights as general creditors of the Employer with respect to benefits due under the Plan or otherwise.

The Trustee shall resume the payment of benefits to Plan participants or their beneficiaries in accordance with the terms of this Agreement only after the Trustee has received a determination from the independent accountant regularly auditing the financial records of the Employer that the Employer is not Insolvent (or is no longer Insolvent).

During the continuance of the Trust, the fees and expenses of the Trustee shall be paid from the Trust Fund if not paid by the Employer.

Amount of Payments After Resumption. Provided that there are sufficient assets, if the Trustee discontinues the payment of benefits from the Trust pursuant to this Section 9 and subsequently resumes such payments, the first payment following such discontinuance shall include the aggregate amount of all payments due to Plan participants or their beneficiaries under the terms of the Plan for the period of such discontinuance, less the aggregate amount of any payments made to Plan participants or their beneficiaries by the Employer in lieu of the payments provided for hereunder during any such period of discontinuance.

Termination. The Trust shall not terminate until the date on which Plan participants and their beneficiaries are no longer entitled to benefits under the terms of the Plan. Upon termination of the Trust, any remaining assets less any outstanding Trust fees and expenses shall be returned to the Employer.

Binding Effect; Assignability. This Agreement shall be binding upon, and the powers granted to the Employer and the Trustee, respectively, shall be exercisable by the respective successors and assigns of the Employer and the Trustee. Any entity which shall, by merger, consolidation, purchase, or otherwise, succeed to substantially all the trust business of the Trustee shall, upon such succession and without any appointment or other action by the Employer, be and become successor trustee hereunder.

Governing Law. This Agreement and the trust created and the Trust held hereunder shall be interpreted in accordance with the laws of the state of Delaware, except to the extent that such laws are preempted by the federal laws of the United States of America. All contributions to the Trust shall be deemed to take place in the state of Delaware.

Notices. Any communication to the Trustee, including any notice, direction, designation, certification, order, instruction, or objection shall be in writing and signed by the person authorized under the Plan to give the communication. The Trustee shall be fully protected in acting in accordance with these written communications. Any notice required or permitted to be given to a party hereunder shall be deemed given if in writing and hand delivered or mailed, postage prepaid, certified mail, return receipt requested, to such party at the following address or at such other address as such party may by notice specify:

Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity of enforceability of the remaining provisions.

Waiver. Failure of any party to insist at any time or times upon strict compliance with any provision of this Agreement shall not be a waiver of such provision at such time or any later time unless in a writing designated as a waiver and signed by or on behalf of the party against whom enforcement of the waiver is sought.

Non-Alienation. No interest, right or claim in or to any part of the Trust or any payment therefrom shall be assignable, transferable or subject to sale, mortgage, pledge, hypothecation, commutation, anticipation, garnishment, attachment, execution, or levy of any kind, and the Trustee and the Committee shall not recognize any attempt to assign, transfer, sell, mortgage, pledge, hypothecate, commute, or anticipate the same, except to the extent required by law.

Definitions. Unless the context of this Agreement clearly indicates otherwise, the terms defined in the Plan shall, when used herein, have the same meaning as in the Plan.

Headings. The headings of sections are included solely for convenience of reference. If there is any conflict between such headings and the text of the Agreement, the text shall control.

Construction of Language. Whenever appropriate in this Agreement, words used in the singular may be read in the plural; words used in the plural may be read in the singular; and words importing the masculine gender shall be deemed equally to refer to the female gender or the neuter. Any reference to a section number shall refer to a section of this Agreement, unless otherwise indicated.
