ARTICLE I
THE MERGER

         1.1      THE MERGER.     Subject to the terms and conditions of this Agreement, including Section 9.11 hereof, in accordance with the Michigan Business Corporation Act, as amended (the "MBCA" ), at the Effective Time, First Federal shall merge with and into MergerSub. MergerSub shall be the Surviving Entity in the Merger and shall continue its existence as a limited liability company under the laws of Michigan, and as a wholly owned Subsidiary of Mackinac. As of the Effective Time, the separate corporate existence of First Federal shall cease.

         1.2      EFFECTIVE TIME.     The Merger shall become effective upon the filing on the Closing Date of the Certificate of Merger (the "Certificate of Merger" ) with the Corporations Division of the Michigan Department of Licensing and Regulatory Affairs ( "LARA" ) as provided in the MBCA. The term "Effective Time" shall be the date and time when the LARA accepts the Certificate of Merger for filing in accordance with the MBCA.

         1.3      CLOSING.     On the terms and subject to the conditions set forth in this Agreement, the closing of the transactions contemplated by this Agreement (the "Closing" ) shall take place at the offices of Honigman Miller Schwartz and Cohn LLP, 660 Woodward Ave, 2290 First National Building, Detroit, Michigan 48226 at a time determined by Mackinac that follows the close of trading on the date that is the later of (i) three (3) Business Days after the satisfaction or waiver (subject to applicable Law) of the latest to occur of the conditions set forth in ARTICLE VII (other than those conditions that by their nature are to be satisfied or waived at the Closing, but subject to the satisfaction of such conditions

         1.4      ARTICLES OF ORGANIZATION OF THE SURVIVING ENTITY.     At the Effective Time, the articles of organization and operating agreement of MergerSub in effect immediately prior to the Effective Time (subject to any amendment to the articles of organization set forth in the Certificate of Merger) shall be the articles of organization and operating agreement of the Surviving Entity until thereafter amended in accordance with applicable Law.

         1.5      TAX CONSEQUENCES.     It is intended that the Merger shall qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a "plan of reorganization" for purposes of Sections 354 and 361 of the Code. From and after the date of this Agreement and until the Closing Date, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could reasonably be expected to prevent the Merger from qualifying as a "reorganization" within the meaning of Section 368(a) of the Code.

         1.6      EFFECTS OF THE MERGER.     Subject to the terms and conditions of this Agreement, at the Effective Time, First Federal shall be merged with and into MergerSub and the separate corporate existence of First Federal shall cease. At the Effective Time, First Federal and MergerSub shall become a single limited liability company as the Surviving Entity. The effect of the Merger upon each of First Federal and the Surviving Entity shall be as provided in Chapter Seven of the MBCA with respect to the merger of domestic corporations with a domestic business organization. Without limiting the generality of the foregoing, and subject to the MBCA, at the Effective Time: (a) all the rights, privileges, powers, franchises, licenses, and interests in and to every type of property (whether real, personal or mixed) of MergerSub and First Federal, shall vest in the Surviving Entity, (b) all choses in action MergerSub and First Federal shall continue unaffected and uninterrupted by the Merger and shall accrue to the Surviving Entity and (c) all debts, liabilities and duties of MergerSub and First Federal shall become the debts, liabilities and duties of the Surviving Entity.

         1.7      CONVERSION OF STOCK.     At the Effective Time, by virtue of the Merger and without any action on the part of Mackinac, MergerSub, First Federal or the holder of any of the following securities (each a "Mackinac Common Shareholder" or a "First Federal Common Shareholder" ):

         (a)      No Effect on Mackinac Common Stock.     Each share of the common stock, no par value per share, of Mackinac (the "Mackinac Common Stock" ), issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

         (e)      Adjustments to Prevent Dilution.     If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of Mackinac or First Federal, respectively, shall occur (or for which the relevant record date will occur) as a result of any reclassification, recapitalization, stock split (including a reverse stock split) or subdivision or combination or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, the Merger Consideration, the Exchange Ratio and any other dependent items, as applicable, shall be equitably and proportionately adjusted, if necessary and without duplication, to reflect such change.

         (f)      Further Adjustments.     In the event that, as of the Determination Date (as defined below):

           (i)   The number obtained by dividing the Average Closing Price by the Mackinac Initial Price is greater than 1.20; and

the Exchange Ratio shall be adjusted such that the Exchange Ratio shall equal the number derived by multiplying the Exchange Ratio by the quotient obtained by dividing (i) the Maximum Adjustment Price by (ii) the Average Closing Price.

        As used herein, the following terms shall have the meanings indicated:

         "Average Closing Price" shall mean the volume weighted average price per share of the Mackinac Common Stock (based on "regular way" trading on the NASDAQ Stock Market only) over the twenty consecutive Trading Days ending on the Trading Day immediately prior to the Determination Date, as calculated by Bloomberg Financial LP under the function "VWAP".

ARTICLE II
DELIVERY OF MERGER CONSIDERATION

         2.1      EXCHANGE AGENT.     Prior to the Effective Time, Mackinac shall appoint a bank or trust company selected by Mackinac and reasonably acceptable to First Federal or Mackinac's transfer agent, pursuant to an agreement (the "Exchange Agent Agreement" ), to act as exchange agent (the "Exchange Agent" ) hereunder.

         2.2      DELIVERY OF MERGER CONSIDERATION.     At or prior to the Effective Time, Mackinac shall (i) authorize the Exchange Agent to deliver an aggregate number of shares of Mackinac and cash equal to the aggregate Merger Consideration to be issued and paid to the First Federal Common Shareholders and (ii) cash sufficient to pay holders of what would have been fractional shares of Mackinac Common Stock pursuant to Section 2.3(e) of this Agreement (the "Exchange Fund" ), and First Federal shall deliver cash sufficient to pay the Special Dividend which shall be promptly paid by the Exchange Agent, pro-rata based on the outstanding First Federal Common Stock on the Closing Date, to the First Federal Common Shareholders .

         2.3      EXCHANGE PROCEDURES.     

         (a)    As a condition to receiving the Merger Consideration for each share of First Federal Common Stock held, each First Federal Common Shareholder shall be required to duly execute

4

and deliver to the Exchange Agent a letter of transmittal (each, a "Letter of Transmittal" ). As promptly as practicable, but in any event no later than five Business Days following the Effective Time, and provided that First Federal has delivered, or caused to be delivered, to the Exchange Agent all information that is necessary for the Exchange Agent to perform its obligations as specified herein, the Exchange Agent shall mail to each holder of record of a First Federal Certificate evidencing such shares (a "First Federal Certificate" ) a Letter of Transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the First Federal Certificate shall pass, only upon delivery of the First Federal Certificate to the Exchange Agent) and instructions for use in effecting the surrender of the First Federal Certificates in exchange for the Merger Consideration as provided for in this Agreement (such Letter of Transmittal and instructions to include applicable provisions with respect to delivery of an "agent's message" or other appropriate instructions with respect to First Federal Certificates that are book-entry shares). Each First Federal Common Shareholder, upon proper surrender of First Federal Certificates to the Exchange Agent, accompanied by duly executed Letters of Transmittal, shall be entitled to receive in exchange therefor (i) the Merger Consideration to which such First Federal Common Shareholder shall have become entitled pursuant to the provisions of Section 1.7, and/or (ii) a check representing the amount of cash in lieu of fractional shares that such holder has the right to receive hereunder. Each First Federal Certificate so surrendered shall be cancelled. Until so surrendered, each First Federal Certificate will be deemed for all purposes after the Effective Time to represent and evidence solely the right to receive the Merger Consideration to be paid therefor pursuant to this Agreement. Except as required by Law, no interest shall be payable with respect to the cash payable for fractional shares. If any First Federal Common Shareholder is unable to locate any First Federal Certificate(s) to be surrendered for exchange, the Exchange Agent shall deliver the corresponding share of the Merger Consideration to the registered Shareholder thereof upon receipt of a lost certificate affidavit and an indemnity agreement in a form acceptable to the Exchange Agent and Mackinac.

         (b)    No dividends or other distributions with respect to Mackinac Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Mackinac Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this ARTICLE II . Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Certificate in accordance with this ARTICLE II , the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Mackinac Common Stock represented by such Certificate and paid prior to such surrender date, and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to the whole shares of Mackinac Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Mackinac Common Stock issuable with respect to such Certificate.

         (c)    In the event of a transfer of ownership of a Certificate representing First Federal Common Stock that is not registered in the stock transfer records of First Federal, the Merger Consideration (including cash in lieu of fractional shares of Mackinac Common Stock) shall be issued or paid in exchange therefor to a Person other than the Person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such First Federal Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment or issuance shall pay any transfer or other similar taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate, or establish to the reasonable satisfaction of Mackinac that the tax has been paid or is not applicable.

5

         (d)    After the Effective Time, there shall be no transfers on the stock transfer books of First Federal of the shares of First Federal Common Stock that were issued and outstanding immediately prior to the Effective Time other than to settle transfers of First Federal Common Stock that occurred 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 cancelled and exchanged for the applicable Merger Consideration and any cash in lieu of fractional shares of Mackinac Common Stock to be issued or paid in consideration therefor in accordance with the procedures set forth in this ARTICLE II .

         (e)    Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of Mackinac Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to Mackinac 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 Mackinac. In lieu of the issuance of any such fractional share, Mackinac shall pay to each former shareholder of First Federal 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, rounded to the nearest one tenth of a cent, of the closing sale prices of Mackinac Common Stock based on information reported by the Nasdaq Stock Market (the "Nasdaq" ) (as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source reasonably selected by Mackinac) for the five (5) trading days immediately preceding the Effective Time (the "Mackinac Closing Price" ) by (ii) the fraction of a share (after taking into account all shares of First Federal Common Stock held by such holder at the Effective Time and rounded to the nearest thousandth when expressed in decimal form) of Mackinac Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.7.

         (f)     Any portion of the Exchange Fund that remains unclaimed by the shareholders of First Federal as of the one year anniversary of the Effective Time may be paid to Mackinac. In such event, any former shareholders of First Federal who have not theretofore complied with this ARTICLE II shall thereafter look only to Mackinac with respect to the Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the Mackinac Common Stock deliverable in respect of each share of First Federal Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Mackinac, First Federal, the Exchange Agent or any other Person shall be liable to any former holder of shares of First Federal Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws.

         (g)    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 reasonably required by Mackinac or the Exchange Agent, the posting by such Person of a bond in such amount as Mackinac 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 applicable Merger Consideration deliverable in respect thereof in accordance with the terms of this Agreement and requirements of this ARTICLE II .

         (b)    Subject to applicable Laws relating to the exchange of information, Mackinac and First Federal shall, upon request, furnish each other with all information concerning Mackinac, First Federal and their respective Subsidiaries, 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 Mackinac, First Federal or any of their respective Subsidiaries to any Governmental Entity in connection with the transactions contemplated by this Agreement.

         (b)    Mackinac and First Federal shall comply with, and shall cause their respective Representatives, directors, officers and employees to comply with, all of their respective obligations under the Confidentiality Agreement, which shall survive the termination of this Agreement in accordance with the terms set forth therein.

         6.3      SEC FILINGS AND SHAREHOLDER APPROVAL.     

         (a)    First Federal and Mackinac shall as promptly as practicable prepare and file with the SEC a joint proxy statement/prospectus relating to the First Federal Shareholders' Meeting and the Mackinac Shareholders' Meeting (the "Joint Proxy Statement" ). First Federal and Mackinac shall as promptly as practicable prepare, and Mackinac shall file with the SEC, a registration statement on Form S-4 (the "Form S-4" ) in which the Joint Proxy Statement will be included as a prospectus, and Mackinac and First Federal shall use their respective reasonable best efforts to cause the Form S-4 to be declared effective by the SEC as promptly as practicable after filing. The Joint Proxy Statement, and any amendment or supplement thereto, shall, except in the case of a withdrawal or modification of the First Federal Board Recommendation expressly permitted by Section 6.3(b), include the First Federal Board Recommendation and the Mackinac Board Recommendation. The parties shall notify each other promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Joint Proxy Statement or the Form S-4 or for additional information and shall supply each other with copies of all correspondence between such party or any of its Representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Joint Proxy Statement, the Form S-4 or the Merger. If, at any time prior to the receipt of the Requisite Shareholder Approvals, any event occurs with respect to First Federal, Mackinac or any of their respective Subsidiaries, or any change occurs with respect to other information supplied by a party for inclusion in the Joint Proxy Statement or the Form S-4, which is required to be described in an amendment of, or a supplement to, the Joint Proxy Statement or the Form S-4, such party shall promptly notify the other party of such event, and First Federal and Mackinac shall cooperate in the prompt filing with the SEC of any necessary amendment or supplement to the Joint Proxy Statement and the Form S-4 and, to the extent required by applicable Law, in disseminating the information contained in such amendment or supplement to the shareholders of First Federal and Mackinac. Without limiting the foregoing, First Federal and Mackinac shall make all necessary filings with respect to the Merger under the Securities Act, the Exchange Act, applicable state blue sky laws and the rules and regulations thereunder, and shall cooperate in seeking timely to obtain any actions, consents, approvals or waivers, and in making any filings or furnishings of information, required in connection therewith (including in connection with the Joint Proxy Statement and the Form S-4).

         (b)    First Federal shall take all action necessary in accordance with the Maryland General Corporation Law and the First Federal Articles of Incorporation and First Federal Bylaws to duly call, give notice of, convene and hold a meeting of its shareholders as promptly as practicable for the purpose of obtaining the First Federal Requisite Shareholder Approval (such meeting or any adjournment or postponement thereof, the "First Federal Shareholders' Meeting" ), and, except in the

38

case of a withdrawal or modification of the First Federal Board Recommendation expressly permitted by this Section 6.3(b), shall solicit, and use its reasonable best efforts to obtain, the First Federal Requisite Shareholder Approval thereat. Except as expressly provided in the immediately following sentence, the board of directors of First Federal shall (i) recommend to its shareholders the approval and adoption of this Agreement and the transactions contemplated herein (the "First Federal Board Recommendation" ), (ii) include the First Federal Board Recommendation in the Joint Proxy Statement and (iii) not approve, agree to or recommend, or propose to approve, agree to or recommend, any Acquisition Proposal or Alternative Transaction. The board of directors of First Federal shall be permitted (x) not to recommend to First Federal's shareholders that they give the First Federal Requisite Shareholder Approval or (y) to otherwise withdraw or modify in a manner adverse to Mackinac the First Federal Board Recommendation, in each case only (A) if after receiving an unsolicited bona fide Acquisition Proposal that constitutes a Superior Proposal, the board of directors of First Federal determines in its good faith judgment, after receiving the advice of outside legal counsel, that, in light of such Superior Proposal, the board of directors would be in violation of its fiduciary duties under applicable law if it failed to withdraw or modify the First Federal Board Recommendation, (B) after the fifth Business Day following delivery by First Federal to Mackinac of written notice advising Mackinac that the board of directors of First Federal intends to resolve to so withdraw or modify the First Federal Board Recommendation absent modification of the terms and conditions of this Agreement; (C) if, assuming this Agreement was amended to reflect all adjustments to the terms and conditions hereof proposed by Mackinac during such five Business Day period, such Acquisition Proposal would nonetheless continue to constitute a Superior Proposal; and (D) if First Federal has complied with its obligations set forth in this Section 6.3(b) (and, if applicable, Section 6.3(c)) and Section 6.9; provided, however, that following each and every material revision to such Superior Proposal, First Federal shall be required to deliver a new written notice to Mackinac in accordance with this Section 6.3(b) and to again comply with the requirements of this Section 6.3(b). Without limiting the foregoing, if the board of directors of First Federal has withdrawn or modified the First Federal Board Recommendation as expressly permitted by this Section 6.3(b), then the board of directors of First Federal may submit this Agreement to First Federal's shareholders without recommendation (although the resolutions adopting this Agreement as of the date hereof may not be rescinded or amended), in which event the board of directors of First Federal may communicate the basis for its lack of a recommendation to First Federal's shareholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by applicable law. For purposes of this Agreement, "Superior Proposal" means a bona fide, unsolicited written Acquisition Proposal that (x) is obtained not in breach of this Agreement for all of the outstanding shares of First Federal Common Stock, on terms that the board of directors of First Federal determines in its good faith judgment (after consultation with outside counsel and a financial advisor and after taking into account all the terms and conditions of the Acquisition Proposal and this Agreement (including any proposal by Mackinac to adjust the terms and conditions of this Agreement), including any break-up fees, expense reimbursement provisions, conditions to and expected timing and risks of consummation, the form of consideration offered and the ability of the party making such proposal to obtain financing for such Acquisition Proposal, and after taking into account all other legal, financial, strategic, regulatory and other aspects of such proposal, including the identity of the party making such proposal, and this Agreement) are more favorable from a financial point of view to its shareholders than the Merger, (y) is reasonably likely to receive all necessary regulatory approvals and be consummated and (z) does not contain any condition to closing or similar contingency related to the ability of the party making such proposal to obtain financing.

         (c)    If an Acquisition Proposal (the terms and conditions of which are more favorable from a financial point of view to First Federal's shareholders than the Merger) shall have been

39

communicated to or otherwise made known to the shareholders of First Federal and thereafter First Federal shall have failed to obtain the First Federal Requisite Shareholder Approval at the First Federal Shareholders' Meeting, then, unless this Agreement shall have been terminated pursuant to its terms, if, during the ten Business Day period following such failure to obtain the First Federal Requisite Shareholder Approval, Mackinac proposes to adjust the terms and conditions of this Agreement such that the transactions contemplated herein (as adjusted) would be no less favorable from a financial point of view to First Federal's shareholders than such Acquisition Proposal, First Federal shall (i) resubmit the transaction to First Federal's shareholders at a second duly called, noticed, convened and held meeting of First Federal's shareholders for the purpose of obtaining the First Federal Requisite Shareholder Approval (such meeting or any adjournment or postponement thereof, the "Second First Federal Shareholders' Meeting" ), with the timing of the Second First Federal Shareholders' Meeting to be determined at the reasonable request of Mackinac and (ii) again otherwise comply with Section 6.3(b) as if the Second First Federal Shareholders' Meeting were the First Federal Shareholders' Meeting; provided, that if (1) prior to the First Federal Shareholders' Meeting the board of directors of First Federal shall have taken (and not reversed or withdrawn) in accordance with Section 6.3(b) any of the actions contemplated by clauses (x) and/or (y) of the third sentence of Section 6.3(b); (2) assuming this Agreement was amended to reflect all adjustments to the terms and conditions hereof proposed by Mackinac during the 10 Business Day period following the failure to obtain the First Federal Requisite Shareholder Approval at the First Federal Shareholders' Meeting, the applicable Acquisition Proposal underlying the First Federal board of directors' actions described in clause (1) above would nonetheless continue to constitute a Superior Proposal; and (3) First Federal has complied with its obligations set forth in Section 6.3(b), this Section 6.3(c) and Section 6.9, then First Federal shall thereafter no longer be bound by the provisions of this Section 6.3(c) (for the avoidance of doubt, without limiting in any respect any other provision of this Agreement) (a "No-Match Event" ).

         (d)    Mackinac shall take all action necessary in accordance with the MBCA and the Mackinac Articles of Incorporation and Mackinac Bylaws to duly call, give notice of, convene and hold a meeting of its shareholders as promptly as practicable for the purpose of obtaining the Mackinac Requisite Shareholder Approval (such meeting or any adjournment or postponement thereof, the "Mackinac Shareholders' Meeting" ), and, except in the case of a withdrawal or modification of the First Federal Board Recommendation expressly permitted by Section 6.3(b) or otherwise, shall solicit, and use its reasonable best efforts to obtain, the Mackinac Requisite Shareholder Approval thereat. Mackinac shall use its commercially reasonable best efforts to cooperate with First Federal to hold the Mackinac Shareholders' Meeting on the same day and at the same time as the First Federal Shareholders' meeting, and to set the same record date for such meeting.

         (e)    Promptly following the execution and delivery of this Agreement, Mackinac, as sole member of MergerSub, shall adopt this Agreement and approve the Merger, in accordance with the Michigan Limited Liability Company Act.

         6.4      PUBLIC DISCLOSURE.     Mackinac and First Federal agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of Mackinac and First Federal. Thereafter, First Federal and Mackinac will consult with and provide each other the reasonable notice of any press release or other public (or non-confidential) statement or comment prior to the issuance of such press release or such other statement or comment relating to this Agreement or the transactions contemplated herein and shall not issue any such press release or such other statement or comment prior to such notice except as may be required by applicable Law. In addition, neither Mackinac nor First Federal shall issue any such press release or such other statement or comment without the prior approval of the other party (which approval shall not be unreasonably withheld or delayed), except as may be required by applicable Law.

40

         6.5      EMPLOYEE BENEFIT MATTERS.     

         (a)    From the Closing Date through the first anniversary thereof, Mackinac shall maintain or cause to be maintained employee benefit plans and compensation opportunities for the benefit of employees (as a group) who are actively employed by First Federal and its Subsidiaries on the Closing Date ( "Covered Employees" ) that provide employee benefits and compensation opportunities that, in the aggregate, are substantially comparable to the employee benefits and compensation opportunities that are generally made available to similarly situated employees of Mackinac or its Subsidiaries (other than First Federal and its Subsidiaries), as applicable; provided that (i) in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of Mackinac or its Subsidiaries; and (ii) until such time as Mackinac shall cause Covered Employees to participate in the employee benefit plans and receive compensation opportunities that are made available to similarly situated employees of Mackinac or its Subsidiaries (other than First Federal and its Subsidiaries), a Covered Employee's continued participation in employee benefit plans of First Federal and its Subsidiaries (on the same terms and conditions offered under such employee benefit plans immediately prior to the Closing Date), and continued opportunity to be eligible for compensation under the plans of First Federal and its Subsidiaries shall be deemed to satisfy the foregoing provisions of this sentence (it being understood that participation in any different Mackinac plans may commence at different times).

         (b)    To the extent that a Covered Employee becomes eligible to participate in an employee benefit plan maintained by Mackinac or any of its Subsidiaries (other than First Federal or its Subsidiaries), Mackinac shall cause such employee benefit plan to recognize the service of such Covered Employee with First Federal or its Subsidiaries for purposes of eligibility, participation, vesting and benefit accrual under such employee benefit plan of Mackinac or any of its Subsidiaries, to the same extent that such service was recognized immediately prior to the Effective Time under a corresponding First Federal Benefit Plan in which such Covered Employee was eligible to participate immediately prior to the Effective Time; provided that such recognition of service shall not (i) operate to duplicate any benefits of a Covered Employee with respect to the same period of service, (ii) apply for purposes of any retiree medical plans or for purposes of benefit accrual under any defined benefit pension plan or (iii) apply for purposes of any plan, program or arrangement that is grandfathered or frozen, either with respect to level of benefits or participation.

         (c)    With respect to any fully insured welfare benefit (health, dental/vision, life/AD&D, LTD) plans currently sponsored by First Federal or its Subsidiaries, Mackinac shall continue each such group insurance contract in force under its current terms after the Effective Time until the end of the plan year or policy year of such welfare benefit plan, provided that , should Mackinac determine, in its sole discretion, that Covered Employees should instead be offered benefits under the welfare benefit plans sponsored by Mackinac or its Subsidiaries, such fully insured welfare benefit plans of First Federal may be may be terminated as of any date on or after the Effective Time in the sole and absolute discretion of Mackinac. With respect to any group health plan of Mackinac or any of its Subsidiaries (other than First Federal and its Subsidiaries) in which any Covered Employee is eligible to participate for the plan year in which such Covered Employee is first eligible to participate, Mackinac shall use commercially reasonable efforts to cause any preexisting condition limitations or eligibility waiting periods under such Mackinac or Subsidiary plan to be waived with respect to such Covered Employee to the extent that such limitation would have been waived or satisfied under the First Federal Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time. In the event some or all of the Covered Employees become eligible to participate in any group health plan of Mackinac or any of its Subsidiaries (other than First Federal and its Subsidiaries) prior to the end of the plan year of the First Federal group health plans which includes the Effective Time, Mackinac shall use

41

commercially reasonable efforts to recognize any health care expenses incurred by such Covered Employee in the year that includes the Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate) for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such health, dental or vision plan of Mackinac or any of its Subsidiaries.

         (d)    No later than one day prior to the Effective Time, the First Federal Board, or, if appropriate, any committee administering the First Federal of Northern Michigan Employees' Savings and Profit Sharing Plan, shall adopt such resolutions or take such other actions as are required to terminate such plan effective on a date that is prior to the Effective Time. First Federal shall preserve all documentation and records related to such plan.

         (e)    Without limiting the generality of Section 9.12, the provisions of this Section 6.5 are solely for the benefit of the parties to this Agreement, and no current or former employee or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement. In no event shall the terms of this Agreement be deemed to (i) establish, amend or modify any First Federal Benefit Plan or any "employee benefit plan" as defined in Section 3(3) of ERISA, or any other benefit plan, program, agreement or arrangement maintained or sponsored by Mackinac, First Federal or any of their respective Affiliates; (ii) alter or limit the ability of Mackinac or any of its Subsidiaries (including, after the Closing Date, First Federal and its Subsidiaries) to amend, modify or terminate any First Federal Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date; or (iii) confer upon any current or former employee, officer, director or consultant any right to employment or continued employment or continued service with the Mackinac or any of its Subsidiaries (including, following the Closing Date, First Federal and its Subsidiaries), or constitute or create an employment agreement with any employee.

         6.6      ADDITIONAL AGREEMENTS.     Subject to the terms and conditions of this Agreement, each of First Federal and Mackinac agree to cooperate fully with each other and to use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective, at the time and in the manner contemplated by this Agreement, the Merger and the Bank Merger. 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 Mackinac, on the one hand, and a Subsidiary of First Federal, on the other) or to vest the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of either party to the Merger, the proper officers and directors of each party and their respective Subsidiaries shall, at Mackinac's sole expense, take all such necessary action as may be reasonably requested by Mackinac.

         6.7      INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.     

         (a)    From and after the Effective Time, each of the Surviving Entity and Mackinac shall indemnify and hold harmless each person who is now, or who has been at any time before the date of this Agreement, or who becomes before the Effective Time, an officer or director of First Federal (each, a "First Federal Indemnified Party" ) against all losses, claims, damages, costs, expenses (including attorneys' fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of the Surviving Entity, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding, investigation or other legal proceeding, whether civil, criminal, administrative or investigative or investigation (each, a "Claim" ), in which an First Federal Indemnified Party is, or is threatened to be made, a party or witness or arising out of the fact that such person is or was a director or officer of First Federal or a Subsidiary if such Claim pertains to any matter of fact arising, existing or occurring at or before the Effective Time (including the Merger and the other transactions

42

contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the fullest extent permitted under the First Federal Articles of Incorporation or First Federal Bylaws to the extent permitted by applicable Law. The Surviving Entity shall pay reasonable expenses (including reasonable attorneys' fees) in advance of the final disposition of any such proceeding to each First Federal Indemnified Party to the full extent permitted by applicable state or federal Law upon receipt of an undertaking to repay such advance payments if he shall be adjudicated or determined to be not entitled to indemnification under this Section 6.7(a).

         (b)    Any First Federal Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 6.7, upon learning of any Claim, shall promptly notify Mackinac and the Surviving Entity thereof. In the event of any such Action (whether arising before or after the Effective Time), (i) Mackinac or the Surviving Entity shall have the right to assume the defense thereof and neither Mackinac nor the Surviving Entity shall be liable to such First Federal Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such First Federal Indemnified Parties in connection with the defense thereof, except that if Mackinac or the Surviving Entity elects not to assume such defense or counsel for the First Federal Indemnified Parties advises that there are substantive issues which raise conflicts of interest between Mackinac or the Surviving Entity and the First Federal Indemnified Parties, the First Federal Indemnified Parties may retain counsel satisfactory to them, and Mackinac or the Surviving Entity shall pay all reasonable fees and expenses of such counsel for the First Federal Indemnified Parties promptly as statements therefor are received; provided that Mackinac and the Surviving Entity shall be obligated pursuant to this paragraph (b) to pay for only one firm of counsel for all First Federal Indemnified Parties in any jurisdiction; (ii) the First Federal Indemnified Parties will cooperate in the defense of any such Claim; and (iii) neither Mackinac nor the Surviving Entity shall be liable for any settlement effected without its prior written consent; and provided, further, that neither Mackinac nor the Surviving Entity shall have any obligation hereunder to any First Federal Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that the indemnification of such First Federal Indemnified Party in the manner contemplated hereby is prohibited by applicable Law.

         (c)    Mackinac shall, or shall cause the Surviving Entity to, use its reasonable best efforts (and First Federal shall cooperate prior to the Effective Time in these efforts) to maintain in effect for a period of six years after the Effective Time First Federal's existing directors' and officers' liability insurance policy ( provided that Mackinac or the Surviving Entity may substitute therefor (i) policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous or (ii) with the consent of First Federal given prior to the Effective Time, any other policy) with respect to claims arising from facts or events which occurred prior to the Effective Time and covering persons who are currently covered by such insurance; provided that neither Mackinac nor the Surviving Entity shall be obligated to make aggregate annual premium payments for such six-year period in respect of such policy (or coverage replacing such policy) which exceed, for the portion related to First Federal's directors and officers, 250% of the annual premium payments on First Federal's current policy in effect as of the date of this Agreement (the "Maximum Amount" ). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Mackinac or the Surviving Entity shall use its reasonable best efforts to maintain the most advantageous policies of directors' and officers' liability insurance obtainable for a premium equal to the Maximum Amount. In lieu of the foregoing, Mackinac, or First Federal with the prior written consent of Mackinac (not to be unreasonably withheld) (in the case of the First Federal, with an aggregate cost not to exceed $100,000), may obtain on or prior to the Effective Time, a six-year "tail" prepaid policy providing equivalent coverage to that described in this Section 6.7(c).

Common Stock immediately prior to such transaction do not, in the aggregate, own at least 80 percent of each of the outstanding shares of First Federal Common Stock and the outstanding voting power of the surviving or resulting entity in such transaction immediately after the consummation thereof in substantially the same proportion as such holders held the shares of First Federal Common Stock immediately prior to the consummation thereof.
