A mechanically reproduced facsimile signature is treated the same as a handwritten signature.

GENERAL AGREEMENTS

NOMINEES

A. Loss sustained by any nominee organized by the Insured for the purpose of handling certain of its business transactions and composed exclusively of its Employees shall, for all the purposes of this bond and whether or not any partner of such nominee is implicated in such loss, be deemed to be loss sustained by the Insured.

ADDITIONAL OFFICES OR EMPLOYEES—CONSOLIDATION, MERGER OR PURCHASE OF ASSETS—NOTICE

B. If the Insured shall, while this bond is in force, establish any additional offices, other than by consolidation or merger with, or purchase or acquisition of assets or liabilities of, another institution such offices shall be automatically covered hereunder from the date of such establishment without the requirement of notice to the Underwriter or the payment of additional premium for the remainder of the premium period.

Page 3 of 8

If the Insured shall, while this bond is in force, consolidate or merge with, or purchase or acquire assets or liabilities of, another institution, the Insured shall not have such coverage as is afforded under this bond for loss which

CHANGE OF CONTROL—NOTICE

C. When the Insured learns of a change in control, it shall give written notice to the Underwriter.

As used in this General Agreement, control means the power to determine the management or policy of a controlling holding company or the Insured by virtue of voting stock ownership. A change in ownership of voting stock which results in direct or indirect ownership by a stockholder or an affiliated group of stockholders of ten percent (10%) or more of such stock shall be presumed to result in a change of control for the purpose of the required notice.

Failure to give the required notice shall result in termination of coverage for any loss involving a transferee, to be effective upon the date of the stock transfer.

REPRESENTATION OF INSURED

D. The Insured represents that the information furnished in the application for this bond is complete, true and correct. Such application constitutes part of this bond.

Any misrepresentation, omission, concealment or incorrect statement of a material fact, in the application or otherwise, shall be grounds for the rescission of this bond.

JOINT INSURED

E. If two or more Insureds are covered under this bond, the first named Insured shall act for all Insureds. Payment by the Underwriter to the first named Insured of loss sustained by any Insured shall fully release the Underwriter on account of such loss. If the first named Insured ceases to be covered under this bond, the Insured next named shall thereafter be considered as the first named Insured. Knowledge possessed or discovery made by any Insured shall constitute knowledge or discovery by all Insureds for all purposes of this bond. The liability of the Underwriter for loss or losses sustained by all Insureds shall not exceed the amount for which the Underwriter would have been liable had all such loss or losses been sustained by one Insured.

NOTICE OF LEGAL PROCEEDINGS AGAINST INSURED—ELECTION TO DEFEND

F. The Insured shall notify the Underwriter at the earliest practicable moment, not to exceed 30 days after notice thereof, of any legal proceeding brought to determine the Insured’s liability for any loss, claim or damage, which, if established, would constitute a collectible loss under this bond. Concurrently, the Insured shall furnish copies of all pleadings and pertinent papers to the Underwriter.

The Underwriter, at its sole option, may elect to conduct the defense of such legal proceeding, in whole or in part. The defense by the Underwriter shall be in the Insured’s name through attorneys selected by the Underwriter. The Insured shall provide all reasonable information and assistance required by the Underwriter for such defense.

If the Underwriter elects to defend the Insured, in whole or in part, any judgment against the Insured on those counts or causes of action which the Underwriter defended on behalf of the Insured or any settlement in which the Underwriter participates and all attorneys’ fees, costs and expenses incurred by the Underwriter in the defense of the litigation shall be a loss covered by this bond.

If the Insured does not give the notices required in subsection (a) of Section 5 of this bond and in the first paragraph of this General Agreement, or if the Underwriter elects not to defend any causes of action, neither a judgment against the Insured, nor a settlement of any legal proceeding by the Insured, shall determine the existence, extent or amount of coverage under this bond for loss sustained by the Insured, and the Underwriter shall not be liable for any attorneys’ fees, costs and expenses incurred by the Insured.

With respect to this General Agreement, subsections (b) and (d) of Section 5 of this bond apply upon the entry of such judgment or the occurrence of such settlement instead of upon discovery of loss. In addition, the Insured must notify the Underwriter within 30 days after such judgment is entered against it or after the Insured settles such legal proceeding, and, subject to subsection (e) of Section 5, the Insured may not bring legal proceedings for the recovery of such loss after the expiration of 24 months from the date of such final judgment or settlement.

LIMIT OF LIABILITY

Section 4.

Aggregate Limit of Liability

The Underwriter’s total liability for all losses discovered during the Bond Period shown in Item 2 of the Declarations shall not exceed the Aggregate Limit of Liability shown in Item 3 of the Declarations. The Aggregate Limit of Liability shall be reduced by the amount of any payment made under the terms of this bond.

Upon exhaustion of the Aggregate Limit of Liability by such payments:

The Aggregate Limit of Liability shall not be increased or reinstated by any recovery made and applied in accordance with subsections (a), (b) and (c) of Section 7. In the event that a loss of Property is settled by the Underwriter through the use of a lost instrument bond, such loss shall not reduce the Aggregate Limit of Liability.

Single Loss Limit of Liability

(e) If any limitation embodied in this bond is prohibited by any law controlling the construction hereof, such limitation shall be deemed to be amended so as to equal the minimum period of limitation provided by such law.

(f) This bond affords coverage only in favor of the Insured. No suit, action or legal proceedings shall be brought hereunder by any one other than the named Insured.

VALUATION

Section 6. Any loss of Money, or loss payable in Money, shall be paid, at the option of the Insured, in the Money of the country in which the loss was sustained or in the United States of America dollar equivalent thereof determined at the rate of exchange at the time of payment of such loss.

Securities

The Underwriter shall settle in kind its liability under this bond on account of a loss of any securities or, at the option of the Insured, shall pay to the Insured the cost of replacing such securities, determined by the market value thereof at the time of such settlement. However, if prior to such settlement the Insured shall be compelled by the demands of a third party or by market rules to purchase equivalent securities, and gives written notification of this to the Underwriter, the cost incurred by the Insured shall be taken as the value of those securities. In case of a loss of subscription, conversion or redemption privileges through the misplacement or loss of securities, the amount of such loss shall be the value of such privileges immediately preceding the expiration thereof. If such securities cannot be replaced or have no quoted market value, or if such privileges have no quoted market value, their value shall be determined by agreement or arbitration.

If the applicable coverage of this bond is subject to a Deductible Amount and/or is not sufficient in amount to indemnify the Insured in full for the loss of securities for which claim is made hereunder, the liability of the Underwriter under this bond is limited to the payment for, or the duplication of, so much of such securities as has a value equal to the amount of such applicable coverage.

Property other than Money, Securities or Records

The Underwriter may, at its election, pay the actual cash value of, replace or repair such property. Disagreement between the Underwriter and the Insured as to the cash value or as to the adequacy of repair or replacement shall be resolved by arbitration.

(c) Recoveries, whether effected by the Underwriter or by the Insured, shall be applied net of the expense of such recovery first to the satisfaction of the Insured’s loss which would otherwise have been paid but for the fact that it is in excess of either the Single or Aggregate Limit of Liability, secondly, to the Underwriter as reimbursement of amounts paid in settlement of the Insured’s claim, and thirdly, to the Insured in satisfaction of any Deductible Amount. Recovery on account of loss of securities as set forth in the second paragraph of Section 6 or recovery from reinsurance and/or indemnity of the Underwriter shall not be deemed a recovery as used herein.
