WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Business Combination and also to prescribe certain conditions to the Business Combination;

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I
THE MERGER

1.1 The Merger.

Subject to the terms and conditions of this Agreement, in accordance with the Delaware General Corporation Law (the "DGCL"), at the Effective Time (as defined in Section 1.2 hereof), Merger Sub shall merge into Herkimer, with Herkimer being the surviving corporation (hereinafter sometimes called the "Surviving Corporation") in the Merger. Upon consummation of the Merger, the corporate existence of Merger Sub shall cease and the Surviving Corporation shall continue to exist as a Delaware corporation and a wholly owned subsidiary of SBU.

1.2 Effective Time.

The Merger shall become effective on the Closing Date (as defined in Section 9.1 hereof), as set forth in the certificate of merger (the "Certificate of Merger") in the form attached as Exhibit B hereto which shall be filed with the Secretary of State of the State of Delaware on the Closing Date. The term "Effective Time" shall be the date and time when the Merger becomes effective on the Closing Date, as set forth in the Certificate of Merger.

1.3 Effects of the Merger.

At and after the Effective Time, the Merger shall have the effects set forth in Sections 259 and 261 of the DGCL.

1.4 Conversion of Herkimer Common Stock.

At the Effective Time, subject to Sections 1.4(b) and 2.2(c) hereof, each share of Herkimer common stock, par value $1.00 per share ("Herkimer Common Stock") issued and outstanding prior to the Effective Time (excluding shares held by stockholders who perfect their dissenters' rights of appraisal as provided in Section 1.4(d) hereof) shall, by virtue of this Agreement and without any action on the part of the holder thereof, be converted into the right to receive an amount of cash that results from dividing (i) $64,000,000 by (ii) the number of shares of Herkimer Common Stock issued and outstanding immediately prior to the Effective Time (the "Merger Consideration"), without interest and subject to adjustment as provided elsewhere herein.

Upon the Effective Time, all of the shares of Herkimer Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each certificate (each a "Certificate") previously representing any such shares of Herkimer Common Stock shall thereafter represent the right to receive the Merger Consideration. Certificates previously representing shares of Herkimer Common Stock shall be exchanged for cash upon the surrender of such Certificates in accordance with Section 2.2 hereof, without any interest thereon. If prior to the Effective Time Herkimer should split or combine its common stock, or pay a dividend or other distribution in such common stock, then the Merger Consideration shall be appropriately adjusted to reflect such split, combination, dividend or distribution.

At the Effective Time, all shares of Herkimer Common Stock that are owned by Herkimer as treasury stock and all shares of Herkimer Common Stock that are owned directly or indirectly by Partners Trust or Herkimer or any of their respective Subsidiaries (other than shares of Herkimer Common Stock held directly or indirectly in trust accounts, managed accounts and the like or otherwise held in a fiduciary capacity that are beneficially owned by third parties (any such shares, and shares of Partners Trust Common Stock which are similarly held, whether held directly or indirectly by Partners Trust or Herkimer, as the case may be, being referred to herein as "Trust Account Shares") and other than any shares of Herkimer Common Stock held by Partners Trust or Herkimer or any of their respective Subsidiaries in respect of a debt previously contracted (any such shares of Herkimer Common Stock, and shares of Partners Trust Common Stock which are similarly held, whether held directly or indirectly by Partners Trust or Herkimer being referred to herein as "DPC Shares")) shall be canceled and shall cease to exist and no cash or other consideration shall be delivered in exchange therefor. All shares of Partners Trust Common Stock that are owned by Herkimer or any of its Subsidiaries (other than Trust Account Shares and DPC Shares) shall become treasury stock of Partners Trust.

Any holder of shares of Herkimer Common Stock who perfects such holder's dissenters' rights in accordance with and as contemplated by Section 262 of the DGCL shall be entitled to receive such payments as may be determined pursuant to such provision of Law; provided that no such payment shall be made to any dissenting stockholder unless and until such dissenting stockholder has complied with the applicable provisions of the DGCL. In the event that after the Effective Time a dissenting stockholder of Herkimer fails to perfect or effectively withdraws or loses such holder's rights to appraisal and of payment of such holder's shares of Herkimer Common Stock, the Surviving Corporation shall issue and deliver the consideration to which such holder of shares of Herkimer Common Stock is entitled under this Section 1.4 (without interest) upon surrender of such holder's Certificate or Certificates.

1.5 Certificate of Incorporation.

At the Effective Time, the Certificate of Incorporation of the Surviving Corporation shall be amended and restated so as to read in its entirety like the Certificate of Incorporation of Merger Sub with Article I of the Certificate of Incorporation amended to read as follows: "The name of the corporation is Herkimer Trust Corporation, Inc."

1.6 Bylaws.

At the Effective Time, the Bylaws of the Surviving Corporation shall be amended and restated so as to read like the Bylaws of Merger Sub.

1.7 Directors and Officers.

At the Effective Time, the directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation. As of the Effective Time, Partners Trust shall amend its bylaws to increase the size of its Board of Directors by one member, and thereupon appoint ▇.▇. ▇▇▇▇▇▇▇ ("▇▇. ▇▇▇▇▇▇▇"), the Chairman and Chief Executive Officer of Herkimer, to serve as an additional member of the Board of Partners Trust in the class of directors whose terms expires at the 2004 annual meeting of stockholders; provided however, that Partners Trust shall have no obligation to appoint ▇▇. ▇▇▇▇▇▇▇ if he is not a member of the Herkimer Board of Directors immediately prior to closing. Partners Trust also shall cause SBU to amend its bylaws to increase the size of its Board of Directors by one member, and thereupon appoint ▇▇. ▇▇▇▇▇▇▇, to serve as an additional member (the "New Member") of the Board of Directors of SBU; provided, however, that SBU shall have no obligation to appoint the New Member to serve on SBU's Board if such person is not a member of the Herkimer Board of Directors immediately prior to closing.

1.8 Modification of Structure

Notwithstanding any provision of this Agreement to the contrary, Partners Trust and SBU, with the prior written consent of Herkimer, which consent shall not be unreasonably withheld or delayed, may elect, subject to the filing of all necessary applications and the receipt of all required regulatory approvals, to modify the structure of the transactions contemplated hereby so long as (i) there are no material adverse federal income tax consequences to the stockholders of Herkimer as a result of such modification; (ii) the consideration to be paid to holders of Herkimer Common Stock under this Agreement is not thereby changed in kind or reduced in amount solely because of such modification; and (iii) such modification will not be likely to materially delay or jeopardize receipt of any required regulatory approvals or impair or prevent the satisfaction of any conditions precedent to the Merger described in Article VII hereof.

ARTICLE II
EXCHANGE Procedures

2.1 SBU to Make Funds Available.

At or prior to the Effective Time, SBU shall deposit, or shall cause to be deposited, with Partners Trust's transfer agent, Registrar and Transfer Company, or such other bank, trust company or transfer agent as SBU may select (the "Exchange Agent"), for the benefit of the holders of Certificates, cash sufficient in the aggregate for the Exchange Agent to make full payment of the Merger Consideration pursuant to Section 1.4 (the "Exchange Fund"). There shall be a written agreement between Partners Trust and the Exchange Agent in which the Exchange Agent expressly undertakes the obligation to pay the Merger Consideration as provided herein. Herkimer shall have the right to review the agreement with the Exchange Agent prior to it being finalized.

2.2 Exchange.

As soon as practicable, but no more than two business days after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates a form letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration pursuant to this Agreement. Upon surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive promptly in exchange therefor a check representing the amount of cash to which such holder shall have become entitled pursuant to the provisions of Article I hereof, and the Certificate so surrendered shall forthwith be canceled. No interest will accrue or be paid to the holder of any outstanding shares of Herkimer Common Stock.

As of the Effective Time, there shall be no transfers on the stock transfer books of Herkimer of the shares of Herkimer Common Stock which were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be canceled and exchanged for the Merger Consideration as provided in this Article II.

Any portion of the Exchange Fund that remains unclaimed by the shareholders of Herkimer six months after the Effective Time may be returned to SBU. After such funds have been returned to SBU, any shareholders of Herkimer who have not theretofore complied with this Article II shall thereafter look only to SBU for payment of the Merger Consideration deliverable in respect of each share of Herkimer Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of SBU, Partners Trust, Merger Sub, Herkimer, the Exchange Agent or any other person shall be liable to any former holder of shares of Herkimer Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by SBU, the posting by such person of a bond in such amount as SBU may reasonably direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate a check representing the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

The reserve for taxes will not be less than the amount shown on the December 31, 2001 financial statements plus the GAAP reserve for fiscal year 2002 taxes, determined without regard to the existence of the reserve on the consolidated balance sheet of Herkimer as of December 31, 2001.

5.2 Merger Covenants.

Notwithstanding that Herkimer believes that it has established all reserves and taken all provisions for possible loan losses required by GAAP and applicable laws, rules and regulations, Herkimer recognizes that Partners Trust may have adopted different loan, accrual and reserve policies (including loan classifications and levels of reserves for possible loan losses). In that regard, and in general, from and after the date of this Agreement to the Effective Time, Herkimer shall consult and cooperate with Partners Trust in order to formulate the plan of integration for the Merger, including, among other things, (i) with respect to conforming, based upon such consultation, Herkimer Bank's loan, accrual and reserve policies to those policies of Partners Trust and in that regard shall, among other things, establish such additional loan loss reserves as necessary to so conform Herkimer Bank's policies and (ii) structure the balance sheet of Herkimer Bank to conform to Partners Trust's business plan and in that regard shall, among other things, change its asset mix as may be reasonably requested; provided, however, that no such additional accruals or loan loss reserves will be required to be made and no change in asset mix will be required to be made (i) more than two business days prior to the Closing Date and (ii) unless Herkimer has received a written certification from Partners Trust that all conditions precedent described in Section 7.1 hereof have been satisfied as of such date (except those by which their nature cannot be satisfied until the Closing Date). No such additional accruals or loan loss reserves made by Herkimer or Herkimer Bank pursuant to this Section 5.2 shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of Herkimer or Herkimer Bank or its management with any such adjustments.

5.3 Compliance with Antitrust Laws.

Each of Partners Trust and Herkimer shall use its reasonable best efforts to resolve objections, if any, which may be asserted with respect to the Merger under antitrust laws, including, without limitation, the HSR Act. In the event a suit is threatened or instituted challenging the Merger as violative of antitrust laws, each of Partners Trust and Herkimer shall use its reasonable best efforts to avoid the filing of, or resist or resolve such suit. Partners Trust and Herkimer shall use their reasonable best efforts to take such action as may be required: (a) by the Antitrust Division of the Department of Justice or the Federal Trade Commission in order to resolve such objections as either of them may have to the Merger under antitrust laws, or (b) by any federal or state court of the United States, in any suit brought by a private party or governmental entity challenging the Merger as violative of antitrust laws, in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order, or other order which has the effect of preventing the consummation of the Merger. Reasonable best efforts shall not include, among other things and to the extent Partners Trust so desires, the willingness of Partners Trust to accept an order agreeing to the divestiture, or the holding separate, of any assets of Partners Trust or Herkimer.

ARTICLE VI
ADDITIONAL AGREEMENTS

6.1 Regulatory Matters.

Partners Trust will prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, and to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and Governmental Entities which are necessary or advisable to consummate the transactions contemplated by this Agreement. Herkimer shall cooperate with Partners Trust to effect the foregoing. Herkimer and Partners Trust shall have the right to review in advance, and to the extent practicable each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to Herkimer or Partners Trust, as the case may be, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement; provided, however, that nothing contained herein shall be deemed to provide either party with a right to review any information provided to any Governmental Entity on a confidential basis in connection with the transactions contemplated hereby. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to contemplation of the transactions contemplated herein.

Herkimer shall, upon request, furnish Partners Trust with all information concerning Herkimer, Herkimer Bank and their directors, officers and shareholders and such other matters as may be reasonably necessary in connection with any statement, filing, notice or application made by or on behalf of Partners Trust to any Governmental Entity in connection with the Business Combination or the other transactions contemplated by this Agreement.

Partners Trust shall, upon request, furnish Herkimer with all information concerning Patrners Trust and SBU as may be reasonably necessary for inclusion in a proxy statement which may be furnished to shareholders of Herkimer in connection with the Special Meeting (as defined in Section 6.3 hereof). None of the information relating to Partners Trust or SBU supplied or to be supplied by Partners Trust or SBU to Herkimer expressly for inclusion in such proxy statement, as of the date such proxy statement is mailed to shareholders of Herkimer and up to and including the date of the meeting of shareholders to which such proxy statement relates, will contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Partners Trust and Herkimer shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement which causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval (defined in Section 7.1(c) hereof) will not be obtained or that the receipt of any such approval will be materially delayed.

6.2 Access to Information.

Upon reasonable notice and subject to applicable Laws relating to the exchange of information, Herkimer shall accord to the officers, employees, accountants, counsel and other representatives of Partners Trust, access, during normal business hours during the period prior to the Effective Time, to all its and Herkimer Bank's properties, books, contracts, commitments and records and, during such period, Herkimer shall make available to Partners Trust (i) a copy of each report, schedule, registration statement and other document filed or received by it (including Herkimer Bank) during such period pursuant to the requirements of federal or state banking laws and (ii) all other information concerning its (including Herkimer Bank) business, properties and personnel as Partners Trust may reasonably request. Partners Trust shall receive notice of all meetings of the Herkimer and Herkimer Bank Board of Directors and any committees thereof, and of any management committees (in all cases, at least as timely as all Herkimer and Herkimer Bank, as the case may be, representatives to such meetings are required to be provided notice). A representative of Partners Trust shall be permitted to attend all meetings of the Board of Directors (except for the confidential portion of such meetings which relate to the Merger or a Competing Proposal ("Confidential Matters") of Herkimer or Herkimer Bank, as the case may be) and such meetings of committees of the Board of Directors and management of Herkimer and Herkimer Bank which Partners Trust desires. Partners Trust will hold all such information in confidence to the extent required by, and in accordance with, the provisions of the Confidentiality Agreement.

No investigation by either of the parties or their respective representatives shall affect the representations and warranties of the other set forth herein.

Herkimer shall provide Partners Trust with true, correct and complete copies of all financial and other information provided to directors of Herkimer and Herkimer Bank in connection with meetings of their Boards of Directors or committees thereof.

6.3 Shareholder Meeting.

Herkimer shall take all steps necessary to duly call, give notice of, convene and hold a meeting of its shareholders within 60 days after the date of this Agreement for the purpose of voting upon the approval of this Agreement and the Merger (the "Special Meeting"). Management and the Board of Directors of Herkimer shall recommend to Herkimer's shareholders approval of this Agreement, including the Merger, and the transactions contemplated hereby, together with any matters incident thereto, and shall oppose any third party proposal or other action that is inconsistent with this Agreement or the consummation of the transactions contemplated hereby; provided, however, that Herkimer shall not be obligated to recommend or oppose, as the case may be, if the Board of Directors of Herkimer determines in good faith, after the receipt of advice from counsel, that such recommendation or opposition, as the case may be, would result in a breach of its fiduciary duties under applicable Delaware law; provided further, however, that notwithstanding anything to the contrary in the foregoing, Herkimer shall hold its Special Meeting in accordance with the time period specified in the first sentence of this Section 6.3.

6.4 Legal Conditions to Business Combination.

Each of Partners Trust and Herkimer shall use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements which may be imposed on such party with respect to the Business Combination and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement and (b) to obtain (and to cooperate with the other party to obtain) any consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party which is required to be obtained by Herkimer or Partners Trust in connection with the Business Combination and the other transactions contemplated by this Agreement.

6.5 Employees.

To the extent permissible under the applicable provisions of the Code and ERISA, for purposes of crediting periods of service for eligibility to participate and vesting, but not for benefit accrual purposes, under the section 401(k) plan maintained by Partners Trust or SBU, as applicable, individuals who are employees of Herkimer or any Subsidiary at the Effective Time and who become eligible to participate in such plans will be credited with periods of service with Herkimer or any Subsidiary before the Effective Time as if such service had been with Partners Trust or SBU, as applicable.

If required by Partners Trust in writing delivered to Herkimer not less than five business days before the Closing Date, Herkimer and each Subsidiary, as applicable, shall, on or before the day immediately preceding the Closing Date, terminate any Plan that includes a qualified cash or deferred arrangement within the meaning of Code Section 401(k) (collectively, the "401(k) Plans") and no further contributions shall be made to any 401(k) Plan after such termination. Herkimer shall provide to Partners Trust (i) certified copies of resolutions adopted by the Board of Directors of Herkimer or such Subsidiary, as applicable, authorizing such termination and (ii) an executed amendment to each 401(k) Plan in form and substance reasonably satisfactory to Partners Trust to conform the plan document for such Plan with all applicable requirements of the Code and regulations thereunder relating to the tax-qualified status of such Plan. Partners Trust and SBU will not be obligated to make any matching or other employer contributions to any 401(k) Plan after the Merger.

After the Effective Time, except to the extent that Partners Trust or its Subsidiaries continues Plans in effect, employees of Herkimer or its Subsidiaries who become employed by Partners Trust or any of its Subsidiaries will be eligible for employee benefits that Partners Trust or such Subsidiary, as the case may be, provides to its employees generally and, except as otherwise required by this Agreement, on substantially the same basis as is applicable to such employees, provided that nothing in this Agreement shall require any duplication of benefits. Partners Trust will or will cause SBU to (i) give credit to employees of Herkimer and its Subsidiaries, with respect to the satisfaction of the limitations as to pre-existing condition exclusions and waiting periods for participation and coverage that are applicable under the employee welfare benefit plans (within the meaning of Section 3(1) of ERISA) of Partners Trust or SBU, equal to the credit that any such employee had received as of the Effective Time towards the satisfaction of any such limitations and waiting periods under the comparable employee welfare benefit plans of Herkimer or its Subsidiaries.

After the Liquidation, Partners Trust and each relevant Partners Trust Subsidiary will honor, without modification, and perform the obligations of Herkimer and Herkimer Bank under, the contracts, plans and arrangements listed in Section 6.5(d) of the Herkimer Disclosure Schedule.

6.8 Advice of Changes.

Partners Trust, SBU and Herkimer shall promptly advise each other of any change or event that, individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect on it or to cause or constitute a material breach of any of its representations, warranties or covenants contained herein. From time to time prior to the Effective Time, each party will promptly supplement or amend its disclosure schedule delivered in connection with the execution of this Agreement to reflect any matter which, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in such disclosure schedule or which is necessary to correct any information in such disclosure schedule which has been rendered inaccurate thereby. No supplement or amendment to such disclosure schedule shall have any effect for the purpose of determining satisfaction of the conditions set forth in Sections 7.2(a) or 7.3(a) hereof, as the case may be, or the compliance by Herkimer with the covenants set forth in Section 5.1 hereof.

6.9 Current Information.

During the period from the date of this Agreement to the Effective Time, Herkimer will cause one or more of its designated representatives to confer on a regular and frequent basis (not less than monthly) with representatives of Partners Trust and SBU and to report the general status of the ongoing operations of Herkimer. Herkimer will promptly notify Partners Trust and SBU of any material change in the normal course of business or in the operation of the properties of Herkimer and of any governmental complaints, investigations or hearings (or communications indicating that the same may be contemplated), or the institution or the threat of litigation involving Herkimer, and will keep Partners Trust and SBU fully informed of such events.

6.13 Indemnification and Insurance.

(a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, in which any person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer or employee of Herkimer or Herkimer Bank (the "Indemnified Parties") is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer or employee of Herkimer or Herkimer Bank or any of their respective predecessors or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate and defend against and respond thereto to the extent permitted by applicable law and the Certificate of Incorporation and Bylaws of Herkimer or Organization Certificate and Bylaws of Herkimer Bank, as the case may be. It is understood and agreed that after the Effective Time, Partners Trust shall indemnify and hold harmless, as and to the fullest extent permitted by applicable law and the Certificate of Incorporation and Bylaws of Herkimer or Organization Certificate and Bylaws of Herkimer Bank, as the case may be, as in effect immediately prior to the Effective Time, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney's fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by law upon receipt of any undertaking required by applicable law), judgments, fines and amounts paid in settlement ("Damages") in connection with any such threatened or actual claim, action, suit, proceeding or investigation, and in the event of any such threatened or actual claim, action, suit, proceeding or investigation (whether asserted or arising before or after the Effective Time), the Indemnified Parties may retain counsel reasonably satisfactory to Partners Trust; provided, however, that (1) Partners Trust shall have the right to assume the defense thereof and upon such assumption Partners Trust shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Partners Trust elects not to assume such defense or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are issues which raise conflicts of interest between Partners Trust and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to Partners Trust, and Partners Trust shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) Partners Trust shall be obligated pursuant to this paragraph to pay for only one firm of counsel for each Indemnified Party, (3) Partners Trust shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld or delayed), and (4) Partners Trust shall not be obligated pursuant to this paragraph to the extent that a final judgment determines that any Damages are as a result of the gross negligence or willful misconduct or result from a decision made by the Indemnified Party when the Indemnified Party had no good faith belief that he or she was acting in the best interests of Herkimer. Partners Trust shall have no obligation to advance expenses incurred in connection with a threatened or pending action, suit or preceding in advance of final disposition of such action, suit or proceeding, unless (i) Partners Trust would be permitted to advance such expenses pursuant to the DGCL and Partners Trust's Certificate of Incorporation or Bylaws, and (ii) Partners Trust receives an undertaking by the Indemnified Party to repay such amount if it is determined that such party is not entitled to be indemnified by Partners Trust pursuant to the DGCL and Partners Trust's Certificate of Incorporation or Bylaws. Any Indemnified Party wishing to claim indemnification under this Section 6.13, upon learning of any such claim, action, suit, proceeding or investigation, shall notify Partners Trust thereof; provided, however, that the failure to so notify shall not affect the obligations of Partners Trust under this Section 6.13 except to the extent such failure to notify materially prejudices Partners Trust. Partners Trust's obligations under this Section 6.13 continue in full force and effect for a period of six years from the Effective Time; provided, however, that all rights to indemnification in respect of any claim asserted or made within such period shall continue until the final disposition of such claim.

If Partners Trust or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any entity, then and in each case, the successors and assigns of Partners Trust shall assume the obligations set forth in this Section 6.13.

(b) Partners Trust shall purchase for the benefit of the persons serving as executive officers and directors of Herkimer and Herkimer Bank immediately prior to the Effective Time, directors' and officers' liability insurance coverage for two years after the Effective Time, under either Herkimer's policy in existence on the date hereof, or under a policy of similar coverage and amounts containing terms and conditions which are generally not less advantageous than Partners Trust's current policy, and in either case, with respect to acts or omissions occurring prior to the Effective Time which were committed by such executive officers and directors in their capacity as such ("Tail Insurance"), provided, however, that Partners Trust shall not be required to expend more than 150% of the current amount expended by Herkimer to maintain or procure insurance coverage pursuant hereto.

by either Partners Trust or Herkimer if the Merger shall not have been consummated on or before April 30, 2003, unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements of such party set forth herein;

by either Partners Trust or Herkimer (provided that the terminating party is not in breach of its obligations under Section 6.3 hereof) if the approval of the shareholders of Herkimer hereto required for the consummation of the Merger shall not have been obtained by reason of the failure to obtain the required vote at a duly held meeting of shareholders or at any adjournment or postponement thereof;

by either Partners Trust or Herkimer (provided that the terminating party is not then in breach of any representation, warranty, covenant or other agreement contained herein that, individually or in the aggregate, would give the other party the right to terminate this Agreement) if there shall have been a breach of any of the representations or warranties set forth in this Agreement on the part of the other party, if such breach, individually or in the aggregate, has had or is likely to have a Material Adverse Effect on the breaching party, and such breach shall not have been cured within 30 days following receipt by the breaching party of written notice of such breach from the other party hereto or such breach, by its nature, cannot be cured prior to the Closing;
