The term “Effective Time” shall be the date and time when the Merger becomes effective, as set forth in the Certificates of Merger, or at such other time as shall be provided by applicable law. 1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the NYBCL, the MGCL and this Agreement. 1.5 Conversion of Adirondack Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Arrow, Merger Sub, Adirondack or the holder of any securities of Arrow or Adirondack: (a) Subject to Sections 1.5(c) and 2.2(e), each share of the common stock, $5.00 par value, of Adirondack (the “Adirondack Common Stock”) issued and outstanding immediately prior to the Effective Time, except for shares of Adirondack Common Stock owned by Adirondack as treasury shares or owned by Arrow or Adirondack (in each case other than shares of Adirondack Common Stock (i) held in any employee benefit plans, trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties or (ii) held, directly or indirectly, by Adirondack or Arrow in respect of debts previously contracted), shall be converted into the right to receive (i) 1.8610 shares (the “Exchange Ratio”, of the common stock, $1.00 par value, of Arrow (the “Arrow Common Stock”) and (ii) $18.72 in cash (“Cash Consideration and collectively with the Exchange Ratio, the “Merger Consideration”). (b) Notwithstanding anything in this Agreement to the contrary, shares of Adirondack Common Stock that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, Sections 623 and 910 of the NYBCL (“Appraisal Shares”) shall not be converted into the Merger Consideration as provided in Section 1.5(a), but instead, at the Effective Time, the Appraisal Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of any such Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive payment of the fair value of such Appraisal Shares in accordance with Sections 623 and 910 of the NYBCL; provided, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Sections 623 and 910 of the NYBCL with respect to such Appraisal Shares or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Sections 623 and 910 of the NYBCL, then the right of such holder to receive the fair value of such holder’s Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for, the right to receive the Merger Consideration as provided in Section 1.5(a), less any applicable tax withholding. Adirondack shall give prompt written notice to Arrow of any demands received by Adirondack for appraisal of any shares of Adirondack Common Stock, and Arrow shall have the right to participate in, and direct all negotiations and Proceedings with respect to such demands. Adirondack shall not, without the prior written consent of Arrow, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of

 
the foregoing. Prior to the Effective Time, Arrow shall not, except with the prior written consent of Adirondack, require Adirondack to make any payment with respect to any demands for appraisal or offer to settle or settle any such demands. (c) All of the shares of Adirondack Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate,” it being understood that any reference herein to an “Old Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of Adirondack Common Stock) previously representing any such shares of Adirondack Common Stock shall thereafter represent only the right to receive (i) a New Certificate representing the number of whole shares of Arrow Common Stock which such shares of Adirondack Common Stock have been converted into the right to receive, (ii) the Cash Consideration, (iii) cash in lieu of fractional shares which the shares of Adirondack Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon, and (iv) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2, without any interest thereon.

(d) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of Adirondack Common Stock owned by Adirondack as treasury shares or owned by Adirondack or Arrow (in each case other than shares of Adirondack Common Stock (i) held in any employee benefit plans, trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or (ii) held, directly or indirectly, by Adirondack or Arrow in respect of debts previously contracted) shall be cancelled and shall cease to exist and no Merger Consideration or other consideration shall be delivered in exchange therefor. 1.6 Treatment of Adirondack Restricted Stock.

Merger Consideration on the same terms as, and shall be treated in the same manner as, all other shares of Adirondack Common Stock in accordance with Section 1.5(a), and (ii) all amounts due and payable pursuant to change in control agreements or other similar payments or benefits under any existing employment, change in control, or other severance agreement or arrangement of Adirondack and its Subsidiaries that become due and payable as a result of the Merger to be paid in full (subject to applicable Taxes required to be withheld, if any, with respect thereto). Adirondack shall, at a regularly scheduled payroll date or a supplemental payroll date prior to the Effective Time, withhold and remit all income and employment taxes resulting from the vesting of such Adirondack Restricted Stock Awards and payments pursuant to this Section 1.6(a)(ii) prior to Closing. (b) At or prior to the Effective Time, Adirondack, the Board of Directors of Adirondack, or the compensation committee of the Board of Directors of Adirondack, as applicable, shall adopt resolutions and take any actions that are necessary to effectuate the treatment of the Adirondack Restricted Stock Awards consistent with the provisions of this Section 1.6. 1.7 Merger Sub Stock. At and after the Effective Time, each share of common stock of Merger Sub, par value $0.01 per share (“Merger Sub Common Stock”), issued and outstanding immediately prior to the Effective Time shall at the Effective Time be converted into and become one share of common stock, $5.00 par value, of the Interim Surviving Corporation. 1.8 Certificate of Incorporation of Interim Surviving Corporation.

Following the consummation of the Holdco Merger, Arrow Bank and Adirondack Bank may, at such time as Arrow elects, consummate the Bank Merger under which Adirondack Bank will merge with and into Arrow Bank pursuant to the Bank Merger Agreement. Arrow Bank shall be the Surviving Bank (the “Surviving Bank”) in the Bank Merger, and shall continue its corporate existence as a national bank. Upon consummation of the Bank Merger, the separate corporate existence of Adirondack Bank shall terminate. The Bank Merger shall become effective at such time and date as Arrow may elect. At such time as Arrow elects to consummate the Bank Merger, Adirondack Bank and Arrow Bank shall execute such certificates of merger and such other documents and certificates as are necessary, required or desirable to make the Bank Merger effective (the “Bank Merger Certificate”). ARTICLE II EXCHANGE OF SHARES 2.1 Arrow to Make Merger Consideration Available. At or prior to the Effective Time, Arrow shall deposit, or shall cause to be deposited, with an exchange agent designated by Arrow (the “Exchange Agent”), for the benefit of the holders of Old Certificates, for exchange in accordance with this Article II, (a) certificates or, at Arrow’s option, evidence of shares in book-entry form (collectively, referred to herein as “New Certificates”), representing the shares of Arrow Common Stock to be issued to holders of Adirondack Common Stock and (b) an amount of cash sufficient to pay the aggregate Cash Consideration payable to holders of Adirondack Common Stock and cash in lieu of any fractional shares (such cash and New Certificates, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”), to be issued pursuant to Section 1.5 and paid pursuant to Section 2.2(a).

 
2.2 Exchange of Shares. (a) As promptly as practicable after the Effective Time, but in no event later than five (5) Business Days thereafter, Arrow shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of Adirondack Common Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive the Merger Consideration pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of Arrow Common Stock, the Cash Consideration and any cash in lieu of fractional shares which the shares of Adirondack Common Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a New Certificate, or, at the election of Arrow, a statement reflecting shares issued in book-entry form, representing that number of whole shares of Arrow Common Stock to which such holder of Adirondack Common Stock shall have become entitled pursuant to the provisions of Article I, and (ii) a check representing the amount of (A) the Cash Consideration, (B) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II and (C) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of Arrow Common Stock which the shares of Adirondack Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to Article I, the Cash Consideration and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2. (b) No dividends or other distributions declared with respect to Arrow Common Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of Arrow Common Stock which the shares of Adirondack Common Stock represented by such Old Certificate have been converted into the right to receive. (c) If any New Certificate representing shares of Arrow Common Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an

 
appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of Arrow Common Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. (d) After the Effective Time, there shall be no transfers on the stock transfer books of Adirondack of the shares of Adirondack Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration, cash in lieu of fractional shares and dividends or distributions as provided in this Article II. (e) Notwithstanding anything to the contrary contained herein, no New Certificates or scrip representing fractional shares of Arrow Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to Arrow Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Arrow. In lieu of the issuance of any such fractional share, Arrow shall pay to each former holder of Adirondack Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of Arrow Common Stock on the Nasdaq Global Select Market (the “Nasdaq”) for the consecutive period of ten (10) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of Adirondack Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest thousandth when expressed in decimal form) of Arrow Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5 . The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares. (f) Any portion of the Exchange Fund that remains unclaimed by the holders of Adirondack Common Stock for twelve (12) months after the Effective Time shall be paid to Arrow. Any former holders of Adirondack Common Stock who have not theretofore complied with this Article II shall thereafter look only to Arrow for payment of the shares of Arrow Common Stock, Cash Consideration, cash in lieu of any fractional shares and any unpaid dividends and distributions on the Arrow Common Stock deliverable in respect of each former share of Adirondack Common Stock that such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Arrow, Adirondack, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of Adirondack Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws.

 
(g) The Surviving Corporation shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the Merger Consideration (including any cash in lieu of fractional shares of Arrow Common Stock), any dividends or distributions payable pursuant to this Section 2.2 or any other consideration otherwise payable pursuant to this Agreement to any holder of Adirondack Common Stock or Adirondack Restricted Stock, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of Tax law. To the extent that amounts are so withheld by Arrow or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Adirondack Common Stock in respect of which the deduction and withholding was made by Arrow or the Exchange Agent, as the case may be. (h) In the event any Old 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 Arrow or the Exchange Agent, the posting by such person of a bond in such amount as Arrow or the Exchange Agent may determine is reasonably necessary 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 the shares of Arrow Common Stock, Cash Consideration, and any cash in lieu of fractional shares, and dividends of distributions, deliverable in respect thereof pursuant to this Agreement without any interest payable thereon.

Notwithstanding the foregoing, neither Arrow nor Adirondack nor any of their respective Subsidiaries shall be required to provide access to or to disclose (x) board and committee minutes that discuss any of the transactions contemplated by this Agreement or (y) information where such access or disclosure would violate or prejudice the rights of Arrow’s or Adirondack’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. (b) Each of Arrow and Adirondack shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the Confidentiality Agreement, dated November 3, 2025, by and between Arrow and Adirondack, as amended, restated or otherwise modified (the “Confidentiality Agreement”).

 
(c) No investigation by either of the parties or their respective representatives shall affect or be deemed to modify or waive the representations and warranties of the other party set forth herein. 6.3 Non-Control. Nothing contained in this Agreement shall give either Arrow or Adirondack, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each of Arrow and Adirondack shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations. 6.4 Shareholder Approvals. (a) Adirondack shall call, give notice of, convene and hold a meeting of its shareholders (the “Adirondack Meeting” to be held as soon as reasonably practicable but no later than 45 days after the S-4 is declared effective, for the purpose of obtaining (a) the Requisite Adirondack Vote, required in connection with this Agreement and the Merger and, (b) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of shareholders in connection with the approval of a merger agreement or the transactions contemplated thereby, and Adirondack shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date and to set the same record date for such meetings. Such meeting may be held virtually, subject to applicable Law and the organizational documents of Adirondack, and Adirondack shall hire a proxy solicitor to assist in obtaining shareholder votes. (b) Subject to Section 6.4(c), Adirondack and its Board of Directors shall use their reasonable best efforts to obtain from the shareholders of Adirondack, including by communicating to the shareholders of Adirondack its recommendation (and including such recommendation in the Proxy Statement) that the shareholders of Adirondack approve this Agreement and the transactions contemplated hereby (the “Adirondack Board Recommendation”). Subject to Section 6.4(c), Adirondack and its Board of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party, the Adirondack Board Recommendation, (ii) the Adirondack Board Recommendation in the Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the Adirondack Board Recommendation within ten (10) Business Days (or such fewer number of days as remains prior to the Adirondack Meeting) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing, a “Recommendation Change”). (c) Subject to Section 8.1 and Section 8.2, if the Board of Directors of Adirondack, after receiving the advice of its outside counsel and, with respect to financial matters, its outside financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable Law to make or continue to make the Adirondack Board Recommendation, the Adirondack Board of Directors may, prior to the

 
receipt of the Requisite Adirondack Vote, submit this Agreement to its shareholders without recommendation (which, for the avoidance of doubt, shall constitute a Recommendation Change) (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event the Adirondack Board of Directors may communicate the basis for its lack of a recommendation to its shareholders in the Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided, that the Adirondack Board of Directors may not take any actions under this sentence unless (i) such action is taken in response to an Acquisition Proposal that is not withdrawn as of the time of taking such action and such Acquisition Proposal constitutes a Superior Proposal and did not result from a breach of Section 6.13, and (ii) the Adirondack Board of Directors (A) gives Arrow at least three (3) Business Days’ prior written notice of its intention to take such action and a reasonable description of the events or circumstances giving rise to its determination to take such action (including the basis for determining that such Acquisition Proposal constitutes a Superior Proposal and the latest material terms and conditions of, and the identity of the third party making, any such Acquisition Proposal, or any amendment or modification thereof), (B) during such three (3) Business Day period, Adirondack has considered and negotiated (and has caused its Representatives to consider and negotiate) with Arrow in good faith (to the extent that Arrow desires to so negotiate) regarding any adjustments or modifications to the terms and conditions of this Agreement, and (C) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by Arrow (if applicable) and, after receiving the advice of Adirondack’s outside counsel and, with respect to financial matters, its outside financial advisors, determines in good faith that (x) it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable Law to make or continue to make the Adirondack Board Recommendation, and (y) such Acquisition Proposal continues to constitute a Superior Proposal. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.4(c) and will require a new determination and notice period as referred to in this Section 6.4(c). 6.5 Legal Conditions to Merger. Subject in all respects to Section 6.1(c) of this Agreement, each of Arrow and Adirondack shall, and shall cause its Subsidiaries to, 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 and regulatory requirements that may be imposed on such party or its Subsidiaries with respect to the Merger, the Holdco Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, including the Merger, the Holdco Merger and the Bank Merger, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, waiver, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by Arrow or Adirondack or any of their respective Subsidiaries in connection with the Merger, the Holdco Merger, the Bank Merger and the other transactions contemplated by this Agreement.

 
6.6 Stock Exchange Listing. (a) Arrow shall cause the shares of Arrow Common Stock to be issued in the Merger to be approved for quotation on the Nasdaq Global Select Marketplace, subject to official notice of issuance, prior to the Effective Time. 6.7 Employee Matters. (a) During the period commencing on the Closing Date and ending on the first anniversary thereof (the “Continuation Period”), Arrow shall or shall cause the Surviving Corporation to provide the employees of Adirondack and its Subsidiaries who continue to be employed by Arrow or its Subsidiaries immediately following the Effective Time and are not subject to retention agreements (the “Continuing Employees”), while employed by the Surviving Corporation or its Subsidiaries after the Effective Time, with annual cash incentive opportunities. Those employees of Adirondack and its Subsidiaries who will not be employed by Arrow or any of its Subsidiaries immediately following the Effective Time, shall be entitled to receive from Adirondack or one of its Subsidiaries prior to the Effective Time (i) severance benefits in a lump sum in accordance with the severance program set forth in Section 6.7(a) of the Adirondack Disclosure Schedule, and (ii) PTO (exclusive of any sick leave) that has accrued but is unused as of the Effective Time. Those employees of Adirondack and its Subsidiaries who are offered retention bonuses pursuant to Section 6.7(c) to remain employed by Arrow or any of its Subsidiaries for a specified period of time following the Effective Time (but not continuing employment beyond the period set forth in the retention agreement), shall receive the same base salary as in effect immediately prior to the Effective Time and shall be entitled to receive from Arrow or one of its Subsidiaries at the end of the retention period if, and only if, such employee does not voluntarily terminate employment or whose employment is terminated for cause prior to the end of such retention period, (i) the amount of such retention bonus, (ii) severance benefits in a lump sum in accordance with the severance program set forth in Section 6.7(a) of the Adirondack Disclosure Schedule, and (ii) PTO (exclusive of any sick leave) that has accrued but is unused as of the Effective Time. Those employees of Adirondack and its Subsidiaries who are offered retention bonuses pursuant to Section 6.7(c) to remain employed by Arrow or any of its Subsidiaries for a specified period of time following the Effective Time and who decline the retention bonus and decide not to remain employed by Arrow or one of its Subsidiaries for the period of time set forth in the retention agreement, shall not be entitled to retention and severance benefits and shall not be entitled to the payment of any PTO that has accrued but is unused as of the Effective Time. (b) Except as otherwise set forth in this Section 6.7, during the Continuation Period, Arrow shall or shall cause the Surviving Corporation to provide the Continuing Employees, while employed by Arrow or its Subsidiaries after the Effective Time, with employee benefits and health insurance that are substantially similar in the aggregate to the employee benefits and health insurance provided to employees of Arrow and its Subsidiaries provided that, for purposes of this Section 6.7(b), employee benefits shall not include any defined benefit pension plan. (c) Arrow and Adirondack may provide a retention pool in the amount set forth in Section 6.7(c) of the Adirondack Disclosure Schedule in retention incentives to certain

 
employees of Adirondack and its Subsidiaries who are not covered by a written employment agreement or change in control agreement for purposes of retaining such employees through and, in some circumstances, after the Closing Date, with the participating employees (including employees that will be retained through and after the Closing Date), amounts, and specific terms of such retention bonuses to be mutually determined by the President and Chief Executive Officer of Adirondack (or his designee) and the President and Chief Executive Officer of Arrow (or his designee). Such retention incentives will be in addition to, and not in lieu of, any severance payment, including the amount that may be paid pursuant to Section 6.7(h). Such designated employees will enter into retention agreements to be provided by Arrow and reasonably acceptable to Adirondack. (d) From and after the Effective Time, Arrow or the Surviving Corporation shall assume and honor all supplemental executive retirement plans that Adirondack and its Subsidiaries have with their current and former officers, directors and employees as listed in Section 6.7(d) of Adirondack Disclosure Schedule. (e) With respect to any employee benefit plans of Arrow or its Subsidiaries in which any Continuing Employees become eligible to participate on or after the Effective Time (the “New Plans”), Arrow shall or shall cause the Surviving Corporation to use best efforts to: (i) waive all exclusions and waiting periods with respect to participation and coverage requirements applicable to such Continuing Employees and their eligible dependents under any New Plans, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Adirondack Benefit Plan, (ii) provide each such Continuing Employee and their eligible dependents with credit for any co-payments and deductibles paid during the year in which the Closing Date occurs prior to the Effective Time under an Adirondack Benefit Plan (to the same extent that such credit was given under the analogous Adirondack Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any New Plans, and (iii) recognize all service of such Continuing Employees with Adirondack and its Subsidiaries (and their respective predecessors, if applicable) for all purposes in any New Plan; for purposes of eligibility, participation and vesting (but not for purposes of benefit accrual) provided that the foregoing service recognition shall not apply (A) to the extent it would result in duplication of benefits for the same period of services, (B) for purposes of any defined benefit pension plan, and (C) to any benefit plan that is a frozen plan or provides grandfathered benefits. (f) Unless otherwise agreed between Arrow and Adirondack, no later than ten (10) days prior to the Closing, effective as of the date immediately preceding the Closing Date and contingent upon the consummation of the Merger, Adirondack shall terminate the Adirondack Bank 401(k) Plan (the “Terminated Plan”). Adirondack shall take (or cause to be taken) all actions that are necessary or appropriate to fully vest all employees in his or her account balance under the Terminated Plan effective as of the Closing Date. Adirondack shall take (or cause to be taken) all actions that are necessary or appropriate to make all employee and employer contributions to the Terminated Plan on behalf of each Continuing Employee in respect of all periods of service ending on or prior to the Closing Date. At least two (2) Business Days prior to the Closing, Adirondack shall provide Arrow with resolutions adopted by Adirondack’s Board of Directors terminating the Terminated Plan the form and substance of which shall be subject to the prior written approval of Arrow, which will not be unreasonably

 
withheld. Continuing Employees shall be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by Arrow or one of its Subsidiaries (the “Arrow 401(k) Plan”), it being agreed that there shall be no gap in participation in a tax-qualified defined contribution plan. Arrow and Adirondack shall take any and all actions as may be required, including amendments to any Arrow 401(k) Plan and/or Terminated Plan, to permit the Continuing Employees who are then actively employed to make rollover contributions to the Arrow 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code), in the form of cash, in kind benefits (if permitted by the Arrow 401(k) Plan), outstanding participant loans or a combination thereof. (g) As of the Effective Time, Arrow shall (i) for Continuing Employees, assume and honor any vacation or personal time off (excluding all sick leave, which for the avoidance of doubt, will not be paid to any employees of Adirondack and its Subsidiaries) (“PTO”) that has accrued but is unused as of the Effective Time under the applicable policies of Adirondack and its Subsidiaries (the “Adirondack PTO Policies”) (including any PTO carried over from a prior year in accordance with Adirondack PTO Policies), (ii) provide additional accruals to Continuing Employees following the Effective Time under the PTO policy of Arrow (“Arrow PTO Policy”) in the same manner as provided to employees of Arrow or its Subsidiaries, (iii) recognize all service of any Continuing Employee with Adirondack and its Subsidiaries for purposes of determining PTO under the Arrow PTO Policy, and (iv) for each employee whose employment is terminated as of the Closing Date, Adirondack shall pay prior to the Effective Time such terminated employee a lump sum cash amount equal to the value of his or her accrued but unused PTO (excluding all accrued sick leave), net of any applicable Taxes. (h) To each eligible Continuing Employee who is not covered by an employment, change in control or similar agreement or plan which provides for severance or similar payments whose employment is terminated involuntarily on or within twelve (12) months following the Closing Date, Arrow shall or shall cause the Surviving Corporation to: (i) provide severance benefits in a lump sum and which is summarized in Section 6.7(h) of the Adirondack Disclosure Schedule, and (ii) provide continued health insurance as required by Law under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) provided such terminated employee timely elects COBRA, with such terminated employee responsible to pay for all COBRA premiums, provided further, that, Arrow’s obligation to provide severance benefits under this Section 6.7(h) is subject to such employee’s execution (and non-revocation) of a release of claims, and provided further that Adirondack will pay prior to the Closing any such severance benefits for employees entitled to a severance payment at Closing. (i) As of the date of this Agreement, Adirondack and Arrow shall enter into settlement agreements with the individuals named in Section 6.7(i) of Adirondack Disclosure Schedule and in the form set forth in Section 6.7(i) of the Adirondack Disclosure Schedule, and which will be signed and dated by the parties on the same date this Agreement is executed. (j) Prior to Closing, Adirondack shall cause Adirondack Bank to transfer ownership of its company-owned automobiles to the individuals named in Section 6.7(j) of the Adirondack Disclosure Schedule, with such individuals to be responsible for any Taxes and tax withholding associated with the transfer of such automobiles, all of which shall be paid prior to the Effective Time.

 
(k) Nothing in this Agreement shall confer upon any employee, officer, director, independent contractor or consultant of Adirondack or any of its Subsidiaries or Affiliates any right to continue in the employ or service of the Surviving Corporation, Adirondack, Arrow or any Subsidiary or Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, Adirondack, Arrow or any Subsidiary or Affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of Adirondack or any of its Subsidiaries or Affiliates at any time for any reason whatsoever, with or without cause. Except as specifically provided in this Agreement, nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Adirondack Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Corporation or any of its Subsidiaries or Affiliates to amend, modify or terminate any particular Adirondack Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including any current or former employee, officer, director, independent contractor or consultant (or any spouse or dependent of such individual) of Adirondack or any of its Subsidiaries or Affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. (l) Adirondack and its Subsidiaries agree to amend immediately after the execution of this Agreement the Adirondack and its Subsidiaries Employee Handbook to reflect the terms and payments provided for under this Section 6.7. 6.8 Indemnification; Directors’ and Officers’ Insurance. (a) From and after the Effective Time, the Surviving Corporation shall indemnify and hold harmless and shall advance expenses as incurred, in each case to the extent (subject to applicable Law and regulation) such persons are indemnified or entitled to such advancement of expenses as of the date of this Agreement by Adirondack pursuant to the Adirondack Certificate, Adirondack Bylaws, the governing or organizational documents of any Subsidiary of Adirondack, any indemnification agreements in existence as of the date hereof that have been disclosed to Arrow, or the NYBCL, each present and former director or officer of Adirondack and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “Adirondack Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages, liabilities and other amounts incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of the fact that such person is or was a director or officer of Adirondack or any of its Subsidiaries and pertaining to matters existing or Occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, the Adirondack Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined in a final determination by a court of competent jurisdiction that such Adirondack Indemnified Party is not entitled to indemnification. (b) For a period of six (6) years after the Effective Time, the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by Adirondack (provided, that the Surviving Corporation may

 
substitute its policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims against the present and former officers and directors of Adirondack or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time; provided, that the Surviving Corporation shall not be obligated to expend, on an annual basis, an amount in excess of 200% of the current annual premium paid as of the date hereof by Adirondack for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, Adirondack, in consultation with, but only upon the consent of Arrow, may (and at the request of Arrow, Adirondack shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year prepaid “tail” policy under Adirondack’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap and, in such case, Arrow shall not have any further obligations under this Section 6.8(b), other than to maintain such prepaid “tail” policy. (c) The provisions of this Section 6.8 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Adirondack Indemnified Party and his or her heirs and representatives. If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving person of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case the Surviving Corporation will cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.8. The obligations of the Surviving Corporation under this Section 6.8 shall not be terminated or modified in a manner so as to adversely affect the Adirondack Indemnified Parties or any other person entitled to the benefit of this Section 6.8 without the prior written consent of the affected Adirondack Indemnified Party or affected person. 6.9 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of Arrow, on the one hand, and a Subsidiary of Adirondack, on the other) or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the Holdco Merger or the Bank Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by Arrow. 6.10 Advice of Changes. Arrow and Adirondack shall each promptly advise the other party of any effect, change, event, circumstance, condition, Occurrence or development (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on it or (ii) that it believes would or would reasonably be expected to cause or constitute a material breach of

 
any of its representations, warranties, obligations, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.10 or the failure of any condition set forth in Sections 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Sections 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.10 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice. 6.11 Litigation. Each party shall give the other party prompt notice of any threatened, legal, administrative, arbitral or other proceedings, claims, actions or governmental or regulatory investigations of any nature against either Arrow, Adirondack, or any of their respective Subsidiaries or any of their current or former directors or executive officers relating to the transactions contemplated by this Agreement (“Litigation”), and shall give the other party the opportunity to participate (at such other’s party’s expense) in the defense or settlement of any such Litigation. To the extent allowed by Law or regulation, each party shall give the other the right to review and comment on all filings or responses to be made by such party in connection with any such Litigation, and will in good faith take such comments into account. No party shall agree to settle any such Litigation without the other party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that the other party shall not be obligated to consent to any settlement which does not include a full release of such other party and its Affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Corporation or any of its Affiliates. 6.12 Corporate Governance. (a) Arrow shall cause Arrow Bank to commit to make the charitable contributions as set forth in Section 6.12(b) of Adirondack Disclosure Schedule. (b) Each of Arrow and Arrow Bank shall take all actions necessary to cause the matters set forth on Exhibit D hereto to occur on the Closing Date. 6.13 Acquisition Proposals. (a) Adirondack agrees that it will not, and will cause each of its Subsidiaries and its officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal (other than the parties to this Agreement and their Representatives) or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment,

 
memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.13) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite Adirondack Vote, Adirondack receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach of this Section 6.13, Adirondack may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal but only to the extent that, prior to doing so, the Board of Directors of Adirondack concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its outside financial advisors) that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable Law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, Adirondack shall have provided such information to Arrow and shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with Adirondack. Adirondack will, and will cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than Arrow with respect to any Acquisition Proposal. Adirondack will promptly (within twenty-four (24) hours) advise Arrow following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide Arrow with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received from or on behalf of the person making such inquiry or Acquisition Proposal in connection with such inquiry or Acquisition Proposal, and will keep Arrow apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Adirondack shall use its reasonable best efforts to (x) enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof and (y) within five (5) Business Days after the date thereof, request and confirm the return or destruction of any confidential information provided to any person (other than the parties to this Agreement and their Representatives in their capacity as such) pursuant to any such agreement. As used in this Agreement, “Acquisition Proposal” means, with respect to Adirondack, other than the transactions contemplated by this Agreement, as it may be amended from time to time, any offer, proposal or inquiry relating to, or any third party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of Adirondack and its Subsidiaries or 25% or more of any class of equity or voting securities of Adirondack or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Adirondack, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting securities of Adirondack or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the

 
consolidated assets of Adirondack, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Adirondack or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of Adirondack. As used in this Agreement, “Superior Proposal” means, with respect to Adirondack, any unsolicited bona fide written offer or proposal made by a third party to consummate an Acquisition Proposal that Adirondack’s Board of Directors determines in good faith (after receiving the advice of its outside counsel and, with respect to financial matters, its outside financial advisors); (x) would, if consummated, result in the acquisition of all, but not less than all, of the issued and outstanding shares of Adirondack’s common stock or all, or substantially all, of the assets of Adirondack; (y) would result in a transaction that (i) involves consideration to the holders of the shares of Adirondack’s common stock that is, after accounting for payment of the Termination Fee that may be required hereunder, more favorable, from a financial point of view, than the consideration to be paid to the holders of shares of Adirondack’s common stock pursuant to this Agreement, considering, among other things, the nature of the consideration being offered, and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond, or in addition to, those specifically contemplated hereby, and which proposal is not conditioned upon obtaining financing and (ii) is, in light of the other terms of such proposal, more favorable to the stockholders of Adirondack than the Merger and the other transactions contemplated by this Agreement; and (z) is reasonably likely to be completed on the terms proposed, in each case, taking into account all legal, financial, regulatory and other aspects of the Acquisition Proposal. 6.14 Public Announcements. Arrow and Adirondack agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by Arrow and Adirondack.

(g) by Adirondack if, without breaching Section 6.13 of this Agreement, Adirondack or Adirondack Bank shall contemporaneously enter into a definitive agreement with a third party providing a Superior Proposal.

 
The party desiring to terminate this Agreement pursuant to clauses (b) through (g) of this Section 8.1 shall give written notice of such termination to the other party in accordance with Section 9.5, specifying the provision or provisions hereof pursuant to which such termination is effected. 8.2 Effect of Termination. (a) In the event of termination of this Agreement by either Arrow or Adirondack as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of Arrow, Merger Sub, Adirondack, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Section 6.2(b), Section 6.14 and this Section 8.2 and Article IX (other than Section 9.1) shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, none of Arrow, Merger Sub or Adirondack shall be relieved or released from any liabilities or damages arising out of its fraud or its willful and material breach of any provision of this Agreement. (b) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of Adirondack or shall have been made directly to the shareholders of Adirondack generally or any person shall have publicly announced (and not withdrawn at least two (2) Business Days prior to the Adirondack Meeting) an Acquisition Proposal, in each case with respect to Adirondack and (A) (x) thereafter this Agreement is terminated by either Arrow or Adirondack pursuant to Section 8.1(c) without the Requisite Adirondack Vote having been obtained (and all other conditions set forth in Sections 7.1 and 7.3 were satisfied or were capable of being satisfied prior to such termination) or (y) thereafter this Agreement is terminated by Arrow pursuant to Section 8.1(d) as a result of a willful breach of this Agreement by Adirondack, and (B) prior to the date that is twelve (12) months after the date of such termination, Adirondack enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then Adirondack shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay Arrow, by wire transfer of same day funds, a fee equal to $3,619,000 (the “Termination Fee”); provided, that for purposes of this Section 8.2(b)(i), all references in the definition of Acquisition Proposal to “25%” shall instead refer to “50%.” (ii) In the event that this Agreement is terminated by Arrow pursuant to Section 8.1(e) or Adirondack pursuant to Section 8.1(g), then Adirondack shall pay Arrow, by wire transfer of same day funds, the Termination Fee within two (2) Business Days of the date of termination.

 
(c) Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages arising out of the other party’s fraud or its willful and material breach of any provision of this Agreement, in no event shall Adirondack be required to pay the Termination Fee more than once. (d) Each of Arrow and Adirondack acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Adirondack fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, Arrow commences a suit which results in a judgment against the Adirondack for the Termination Fee or any portion thereof, Adirondack shall pay the costs and expenses of Arrow (including reasonable attorneys’ fees and expenses) in connection with such suit. In addition, if Adirondack fails to pay the amounts payable pursuant to this Section 8.2, then Adirondack shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the “prime rate” published in The Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full. The amount payable by Adirondack pursuant to Section 8.2(b), and this Section 8.2(d), constitute liquidated damages and not a penalty, and except in the case of fraud or willful and material breach, shall be the sole monetary remedy of Arrow in the event of a termination of this Agreement specified in such applicable section.

4 necessary to authorize the execution and delivery of this Agreement by the Shareholder or the performance of his or her obligations hereunder; (d) the execution and delivery of this Agreement by the Shareholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof will not, conflict with or violate any law or result in any breach of or violation of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien on any of the Shares pursuant to, any agreement or other instrument or obligation binding upon the Shareholder or the Shares (including under the certificate of incorporation and bylaws of Adirondack), nor require any authorization, consent or approval of, or filing with, any Governmental Entity; (e) the Shareholder beneficially owns (as such term is used in Rule 13d-3 of the Exchange Act) and has the power to vote or direct the voting of the Shares, and the number of such Shares as of the date of this Agreement is identified on the signature page hereto; (f) the Shareholder beneficially owns the Shares free and clear of any proxy, voting restriction, adverse claim or other lien (other than any restrictions created by this Agreement or under applicable federal or state securities laws); and (g) the Shareholder has read and is familiar with the terms of the Merger Agreement. The Shareholder agrees that the Shareholder shall not take any action that would make any representation or warranty of the Shareholder contained herein untrue or incorrect or have the effect of preventing, impairing, delaying or adversely affecting the performance by the Shareholder of his or her obligations under this Agreement. The Shareholder agrees, without further consideration, to execute and deliver such additional documents and to take such further actions as are necessary or reasonably requested by Arrow to confirm and assure the rights and obligations set forth in this Agreement. 6.

Entire Agreement; Assignment. The recitals are incorporated as a part of this Agreement. This Agreement and the Merger Agreement constitute the entire agreement among the parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, other than, if the Shareholder is a director or officer of Adirondack, with respect to any employment, non-competition, non-solicit or consulting agreement between the Shareholder and either Arrow or Adirondack, or its affiliates. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. This Agreement shall not be assigned by operation of law or otherwise and shall be binding upon and inure solely to the benefit of each party hereto; provided, however, that the rights under this Agreement are assignable by Arrow to a majority-owned

 
5 affiliate or any successor-in-interest of Arrow, but no such assignment shall relieve Arrow of its obligations hereunder. 8. Remedies/Specific Enforcement. Each of the parties hereto agrees that this Agreement is intended to be legally binding and specifically enforceable pursuant to its terms and that Arrow would be irreparably harmed if any of the provisions of this Agreement are not performed in accordance with its specific terms and that monetary damages would not provide adequate remedy in such event. Accordingly, in the event of any breach or threatened breach by the Shareholder of any covenant or obligation contained in this Agreement, in addition to any other remedy to which Arrow may be entitled (including monetary damages), Arrow shall be entitled to seek injunctive relief to prevent breaches or threatened breaches of this Agreement and to specifically enforce the terms and provisions hereof, and the Shareholder hereby waives any defense in any action for specific performance or an injunction or other equitable relief that a remedy at law would be adequate. The Shareholder further agrees that neither Arrow nor any other person or entity shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this paragraph, and the Shareholder irrevocably waives any right he or she may have to require the obtaining, furnishing or posting of any such bond or similar instrument. 9.
