enrollment requirements within thirty (30) days after the date he first becomes

                                        3



election as soon as administratively practicable after such deferral election is
submitted to and accepted by the Committee.

     If a Director fails to meet all requirements contained in this Section 3
within the period required, the Director shall not be eligible to participate in
the Plan during such Plan Year.

     3.04 ACCOUNTS. Company agrees to create a Deferred Money Account and a
Stock Unit Account as described in Section 4 below to be maintained on the books
of Company in the name of each Participant.

     Section 4. ALLOCATIONS TO ACCOUNT.

     4.01 PARTICIPANT CONTRIBUTIONS. Each Participant shall defer all or any
portion (subject to a minimum required deferral of at least 25%) of his
director's salary (if any), retainer and fees which are earned for the year from
any Participating Company commencing after the date of said election as he may
specify in said written notice to the Participating Company, and such amounts so
deferred shall be paid only as provided in the Plan. Participant may change the
amount of, or suspend, future deferrals with respect to the Director's salary
(if any), fees and retainers earned for years commencing after the date of
change or suspension as he may specify by written notice to the Participating
Company; provided such change is made prior to January 1 of the calendar year in
which the amount to be deferred is earned.

     4.02 CONTRIBUTION TO STOCK UNIT ACCOUNT. For each Participant electing to
participate in this Plan, each Participating Company for whom the Participant
has made a deferral election shall maintain a Deferred Money Account which shall
be converted quarterly into a Stock Unit Account for each Plan Participant. Each
Participant shall be furnished quarterly with a statement of his Accounts.

     The deferred salary (if any), retainers and fees of each Participant shall
be credited as a dollar amount to the Participant's Deferred Money Account on
the date the amount would otherwise be payable to Participant and shall be
converted into stock units quarterly at each of the Valuation Dates by dividing
the dollar balance of such Deferred Money Account as of the end of each quarter
by the price of a share of IBT common stock as determined by the IBT Bancorp,
Inc. Stockholder Dividend Reinvestment and Employee Stock Purchase Plan, or if
said plan is not in operation at that time, as determined by the Board of
Directors of IBT. The number of stock units for full shares so determined shall
be credited to the Participant's Stock Unit Account and the aggregate value
thereof at said closing price shall be charged to the Participant's Deferred
Money Account. Any cash balance remaining in the Participant's Deferred Money
Account after such charge shall be aggregated with subsequent credits to the
Account at the next Valuation Date to be converted into additional stock units.

     Additional credits will be made to each Participant's Deferred Money
Account in dollar amounts equal to the cash dividends (or the fair market value
of dividends paid in property) the Participant would have received from time to
time had he been the owner on the record dates with respect thereto of the
number of shares of IBT common stock equal to the number of stock units in his
Stock Unit Account on such dates. In the case of a stock dividend or stock
split, additional credits will be made to each Participants' Stock Unit Account
of the number of stock units equal to


                                        4



the number of full shares of IBT common stock in the case of a stock dividend or
a stock split which such Participant would have received from time to time had
he been the owner on the record dates with respect thereto of the number of
shares of IBT common stock equal to the number of stock units in his Stock Unit
Account on such dates.

     Section 5. VESTING.

     Subject to satisfying the distribution events set forth in Section 6 below,
Participant's interest in his Deferred Money Account and his Stock Unit Account
shall be 100% vested and nonforfeitable at all times.

     Section 6. COMMENCEMENT OF DISTRIBUTION.

     6.01 DISTRIBUTION DATES. The form and manner in which distributions will be
made from the Plan shall be determined in accordance with Section 7 below. No
amount standing from time to time to the credit of the Participant in his
Deferred Money Account or his Stock Unit Account shall be assignable or
alienable by Participant, nor may any such payment be used as collateral or in
any other fashion by Participant prior to payment by the Company. Subject to
Section 6.03 below, no amount standing from time to time to the credit of
Participant in his Deferred Money Account or his Stock Unit Account shall be
payable to Participant (or to Participant's Beneficiary) until the earliest of
the following distribution dates:

          (e)  a Change of Control; or

          (f)  Participant's complete Separation From Service with Company.

     6.02 TIME OF DISTRIBUTION. When the amounts credited to Participant's
Deferred Money Account and Stock Unit Account become payable pursuant to Section
6.01 above, distribution of such benefit shall begin on the first day of the
sixth month following the first Valuation Date immediately following the
earliest distribution date, or as soon as administratively practicable
thereafter.

     Notwithstanding the foregoing, Participant may elect A delayed distribution
date. The delayed distribution date may be a specific future date or the
attainment of a specified age by the Participant (not to exceed the
Participant's attainment of age 75), so long as the delayed distribution date
is:


                                        5



     (a)  requested at least twelve (12) months prior to the earliest
          distribution date;

     (b)  the election does not take effect until at least twelve (12) months
          after the date on which the election is made; and

     (c)  the payment is postponed for a period of not less than five (5) years
          from the date the payment would otherwise have been made.

     6.03 ACCELERATING THE TIME OF PAYMENT. Notwithstanding the distribution
dates set forth in Section 6.01 above, an early distribution may be made as soon
as administratively possible in accordance with IRS Prop. Reg. 1.409A-3(h)(2)
and subsequent guidance following the occurrence of any of the following events:

     (a)  to fulfill the requirements of a domestic relations order;

     (b)  as necessary to comply with a certificate of divestiture as defined in
          Code Section 1043(b)(2);

     (c)  to make payment of certain employment and/or income taxes;

     (d)  de minimis cashout amounts not exceeding $10,000;

     (e)  in accordance with an Unforeseeable Financial Emergency as described

     (f)  certain arrangement terminations of the Plan as described in Section
          11 hereof.

     6.04 DELAYING PAYMENTS UNDER CERTAIN CIRCUMSTANCES. A payment may be
delayed in accordance with IRS Prop. Reg. 1.409A-2(b)(5) (and such other
guidance published after the Effective Date) under the following circumstances
as described in the Regulation:

     (a)  Payments subject to Code Section 162(m) where the Company reasonably
          anticipates that its deduction with respect to such payment would be
          limited or eliminated by the application of Code Section 162(m).

     (b)  Payments that would violate a loan covenant or similar contractual
          requirement of the Company, where such violation would cause material
          harm to the Company and the Company entered into the agreement or
          covenant for legitimate business reasons and not to avoid restrictions
          under Code Section 409A;

     (c)  Payments that would violate Federal securities laws or other
          applicable laws; or

     (d)  Such other events and conditions as permitted by applicable law.


                                        6



     Any missed or delayed payments shall be made to the Participant (or to his
Beneficiary) at the earliest date at which the Company reasonably anticipates
that the payment will not cause the harm to be avoided by the application of
this Section 6.04.

     Section 7. MANNER AND FORM OF DISTRIBUTION.

     7.01 MANNER OF PAYMENT. Upon the occurrence of a distribution event set
forth in Section 6, the Participant shall receive:

          (a)  payment in cash of the balance in his Deferred Money Account
               maintained with the Participating Company, if any, remaining
               after the last Valuation Date occurring in the calendar year of
               the distribution event, but after the date of the distribution
               event; and

          (b)  payment of the balance in his Stock Unit Account maintained with
               the Participating Company as of the date of the distribution
               event, in shares of IBT common stock, or at the option of the
               Participant as he directs by written notice delivered to the
               Participating Company within thirty (30) days after the date of
               the distribution event, in cash equal to the purchase cost of
               such shares, or in any combination of stock or cash.

     7.02 FORM OF PAYMENT. Participant's benefit payable from the Plan Account
shall be distributed in a single lump sum, unless an election is made to change
the form of payment to an installment payment by submitting an election form to
the Committee in accordance with the following:

     (a)  the election shall have no effect until at least twelve (12) months
          after the date the election is made; and

     (b)  the first benefit payment shall be delayed at least five (5) years
          from the Participant's originally scheduled benefit commencement date
          described in Section 6.01.

     Installment payments made under this Section 7.02 shall be equal annual
installments payable over a period of ten (10), fifteen (15) or twenty (20)
years, said installment payments to be treated as a single payment pursuant to
IRS Prop. Reg. 1.409A-2(b)(2)(iii) and future guidance; provided however,
pursuant to IRS Prop. Reg. 1.409A-2(h)(1) and other applicable law, if
Participant dies before all installment payments have been made, all remaining
amounts shall be paid to Participant's Beneficiary in a single lump sum.

     Notwithstanding the foregoing, the Committee shall interpret all provisions
relating to changing the form of benefit payment under this Section 7.02 in a
manner that is consistent with Code Section 409A and other applicable tax law,
including but not limited to Treasury guidance or Regulations issued after the
Effective Date. Accordingly, if a Participant's subsequent benefit distribution
election would result in the changing of the length of the benefit payment
period (e.g., a Participant changes an existing distribution election from
annual installments to a lump sum payment; from 10 annual installments to 5
annual installments, etc.), and the Committee determines such


                                        7



election to be inconsistent with Code Section 409A or other applicable tax law,
the election shall not be effective.

     Section 8. PAYOUT/SUSPENSIONS FOR UNFORESEEABLE FINANCIAL EMERGENCY.

     (a)  If the Participant experiences an Unforeseeable Financial Emergency,
          the Participant may petition the Committee to suspend deferrals to the
          extent deemed necessary by the Committee to satisfy the Unforeseeable
          Financial Emergency. If suspension of deferrals is not sufficient to
          satisfy the Participant's Unforeseeable Financial Emergency, or if
          suspension of deferrals is not required under Code Section 409A and
          other applicable tax law, the Participant may further petition the
          Committee to receive a partial or full payout from the Plan. The
          Participant shall receive a payout from the Plan only to the extent
          such payout is deemed necessary by the Committee to satisfy the
          Participant's Unforeseeable Financial Emergency, plus amounts
          necessary to pay taxes reasonably anticipated as a result of the
          distribution.

          Deferrals made under the Plan may also be suspended if the Participant
          is required under IRS Regulation 1.401(k) - 1(d)(3) to cancel all
          deferral elections to be eligible to receive a hardship distribution
          under an arrangement subject to Code Section 401(k).

     (b)  The payout shall not exceed the lesser of (i) the vested balance in
          the Participant's Accounts, calculated as of the close of business on
          or about the date on which the amount becomes payable, as determined
          by the Committee in its sole discretion, or (ii) the amount necessary
          to satisfy the Unforeseeable Financial Emergency, plus amounts
          necessary to pay taxes reasonably anticipated as a result of the
          distribution. Notwithstanding the foregoing, a Participant may not
          receive a payout from the Plan to the extent that the Unforeseeable
          Financial Emergency is or may be relieved (A) through reimbursement or
          compensation by insurance or otherwise, (B) by liquidation of the
          Participant's assets, to the extent the liquidation of such assets
          would not itself cause severe financial hardship or (C) by suspension
          of deferrals under this Plan, if the Committee, in its sole
          discretion, determines that suspension is required by Code Section
          409A and other applicable tax law. A deferral election made after the
          termination of a deferral election due to an Unforeseeable Financial
          Emergency shall be treated as an initial deferral election.

     (c)  If the Committee, in its sole discretion, approves a Participant's
          petition for suspension, the Participant's deferrals under this Plan
          shall be suspended as of the date of such approval. If the Committee,
          in its sole discretion, approves a Participant's petition for
          suspension and payout, the Participant's deferrals under this Plan
          shall be suspended as of the date of such approval and the Participant
          shall receive a payout from the Plan in a single lump sum within sixty
          (60) days of the date of such approval.

     (d)  Notwithstanding the foregoing, the Committee shall interpret all
          provisions relating to suspension and/or payout under this Section 8
          in a manner that is consistent with


                                        8



          Code Section 409A and other applicable tax law, including but not
          limited to Treasury guidance and Regulations issued after the
          Effective Date.

     Section 9. DEATH BENEFIT.

     9.01 BENEFICIARY DESIGNATION. Participant may designate a Beneficiary to
receive any benefit payable to Participant from this Plan in the event of
Participant's death prior to the complete distribution of benefits payable under
the Plan. The benefit shall be distributed in a single lump sum.

     9.02 PAYMENT OF DEATH BENEFIT. The death benefit payable under the Plan
shall be paid in accordance with the rules described in Section 9.02(a) through
(e) below.

          (a)  The designation of a Beneficiary shall be effective when made on
               a form supplied by the Plan Administrator, signed by Participant
               and actually received and approved in writing by the Plan
               Administrator.

          (b)  No Beneficiary shall have any rights under this Plan until the
               death of Participant. Participant may revoke a Beneficiary
               designation at any time prior to Participant's demise and
               designate an alternative death benefit Beneficiary. Participant
               may designate primary and contingent Beneficiaries. A contingent
               Beneficiary designation will become effective only after the
               death of any and all primary Beneficiaries.

          (c)  If more than one Beneficiary is named in either category (primary
               or contingent), benefits will be paid according to the following
               rules:

               (i)  Beneficiaries may be designated to share equally or to
                    receive specific percentages of the amount distributed; and

               (ii) If a Beneficiary dies before Participant dies, only
                    surviving Beneficiaries will be eligible to receive any
                    benefits in the event of the death of the Participant. If
                    more than two Beneficiaries are originally named to receive
                    different percentages of the benefit, surviving
                    Beneficiaries will share in the same proportion to each
                    other as indicated in the original designation.

          (d)  A person, trust, estate or any other legal entity may be
               designated as a Beneficiary.

          (e)  If a Beneficiary has not been designated, or if a Beneficiary
               designation is ineffective for any reason, Participant's estate
               shall be the Beneficiary.


                                        9



     Section 10. UNSECURED UNFUNDED PLAN.

     Participant's Deferred Money Account and Stock Unit Account shall be
bookkeeping accounts only, and Company shall not be required in any way to fund
the Accounts. Company shall have no obligation to set aside, earmark, or entrust
any fund, policy or money with which to pay its obligation under this Plan.
Participant, or any successor in interest, shall be and remain a general
creditor of Company with respect to amounts deferred under this Plan in the same
manner as any other unsecured creditor who has a general claim for an unpaid
liability. Company shall be the sole owner and beneficiary of any assets
acquired for its general account under this Plan. Company shall not make any
loans or extend credit to Participant, or any successor in interest, which shall
be offset by benefits payable under this Plan.

     Section 11. PLAN AMENDMENT AND TERMINATION.

     IBT may amend or terminate the Plan by action of its Board of Directors at
any time in its sole discretion without the consent of Participant or his
Beneficiary. No amendment or termination shall adversely affect the benefit to
which Participant or his Beneficiary is entitled under the Plan prior to the
date of such amendment or termination. In the event of Plan termination, all
amounts credited to Participant's Deferred Money Account and Stock Unit Account
shall be paid after said Plan termination to Participant or his Beneficiary at
the time and in the form set forth in Sections 6 and 7 above.

     Notwithstanding the foregoing termination distribution provisions, in the
event the Company entirely terminates all account balance deferred compensation
plans that would be aggregated with this Plan under IRS Prop. Reg. 1.409A-1(c)
and subsequent guidance, with respect to all plan participants, all amounts
payable under this Plan on account of the termination shall be distributed in
accordance with IRS Prop. Reg. 1.409A(h)(2)(viii)(C) (and such other Treasury
guidance or Regulations issued after the Effective Date) not less than twelve
(12) months and not more than twenty-four (24) months following the termination
date. Furthermore, the Company shall not establish or adopt any new arrangement
that would be aggregated under Prop. Reg. 1.409A-1(c) with this Plan for a
period of five (5) years following the termination date. In addition, to the
extent permissible under Code Section 409A and other applicable tax law,
including but not limited to Notice 2005-1 and such other Treasury guidance or
Regulations issued after the Effective Date, following a Change of Control the
Employer shall be permitted to (i) terminate the Plan by action of its Board of
Directors, and (ii) distribute the vested Account balances to Participants in a
lump sum no later than twelve (12) months after the date of the Change of
Control.

     Section 12. EXPENSES.

     Company shall pay all costs, charges and expenses relating to the
establishment and operation of the Plan.

     Section 13. NONASSIGNABILITY.

     The benefits payable under the Plan and the right to receive future
benefits under the Plan may not be anticipated, alienated, pledged, encumbered
or subject to any charge or legal process, and if


                                       10



any attempt is made to do so, or if a person eligible for any benefits becomes
bankrupt, the interests under the Plan of the person affected may be terminated
by the Administrator which, in its sole discretion, may cause the same to be
held or applied for the benefit of one or more dependents of such person or make
any other disposition of such benefits that it deems appropriate.

     Section 14. DIRECTOR STATUS.

     The Plan does not, and will not, give any Participant the right to continue
as a Director of a Company, nor will the Plan confer any right to any benefit
under the Plan unless such right has specifically accrued under the terms of the
Plan.

     Section 15. ADMINISTRATION.

     The Boards of Directors of the Participating Companies shall appoint an
impartial Administrative Committee consisting of individuals who are not
participants in the Plan. The Administrative Committee shall have the sole and
exclusive discretionary authority to construe and interpret the terms and
provisions of this Plan, make factual determinations and decide all questions of
eligibility and the amount and time of any benefit payment. Such interpretations
shall be final and binding on all persons. No member of the Administrative
Committee shall, in any event, be liable to any person for any action taken or
omitted in connection with the interpretation, construction or administration of
this Plan, so long as such action or omission to act be made in good faith. In
no event, however, shall the provisions of Section 10 or any other provisions in
this Plan prevent the Participant from seeking legal recourse for any claim he
may have under this Plan.

     The Committee shall have the authority to adopt, alter and repeal such
administrative rules, guidelines and practices governing this Plan as it shall,
from time to time, deem advisable. It may delegate such ministerial functions as
necessary for the operation of the Plan to its agents, including, but not
limited to:

          (a)  maintenance of rules determining eligibility for participation
               and benefits;

          (b)  maintenance of records and bookkeeping, including but not limited
               to the amount payable by each participating Company to its
               respective Participants;

          (c)  calculation and payment of benefits;

          (d)  making recommendations to the Administrator with respect to Plan
               administration; and

          (e)  establishing and carrying out a funding policy and method
               consistent with the objectives of the Plan.

     The Committee's interpretations and determinations shall be final and
binding on all persons and parties concerned. The Committee may make such
provision to withhold any taxes which it is required to withhold from any
applicable benefit payment. Participant, however, shall be responsible for the
payment of all individual tax liabilities relating to any such payment.


                                       11



     Section 16. CLAIMS PROCEDURE.

     16.01 PRESENTATION OF CLAIM. Any Participant or Beneficiary of a deceased
Participant (such Participant or Beneficiary being referred to below as a
"Claimant") may deliver to the Committee a written claim for a determination
with respect to the amounts distributable to such Claimant from the Plan. If
such a claim relates to the contents of a notice received by the Claimant, the
claim must be made within sixty (60) days after such notice was received by the
Claimant. All other claims must be made within 180 days of the date on which the
event that caused the claim to arise occurred. The claim must state with
particularity the determination desired by the Claimant.

     16.02 NOTIFICATION OF DECISION. The Committee shall consider a Claimant's
claim within a reasonable time, but no later than ninety (90) days after
receiving the claim. If the Committee determines that special circumstances
require an extension of time for processing the claim, written notice of the
extension shall be furnished to the Claimant prior to the termination of the
initial ninety (90) day period. In no event shall such extension exceed a period
of ninety (90) days from the end of the initial period. The extension notice
shall indicate the special circumstances requiring an extension of time and the
date by which the Committee expects to render the benefit determination. The
Committee shall notify the Claimant in writing:

     (a)  that the Claimant's requested determination has been made, and that
          the claim has been allowed in full; or

     (b)  that the Committee has reached a conclusion contrary, in whole or in
          part, to the Claimant's requested determination, and such notice must
          set forth in a manner calculated to be understood by the Claimant:

          (i)  the specific reason(s) for the denial of the claim, or any part
               of it;

          (ii) specific reference(s) to pertinent provisions of the Plan upon
               which such denial was based;

          (iii) a description of any additional material or information
               necessary for the Claimant to perfect the claim, and an
               explanation of why such material or information is necessary;

          (iv) an explanation of the claim review procedure set forth in Section
               16.03 below; and

          (v)  a statement of the Claimant's right to bring a civil action
               following an adverse benefit determination on review.

     16.03 REVIEW OF A DENIED CLAIM. On or before sixty (60) days after
receiving a notice from the Committee that a claim has been denied, in whole or
in part, a Claimant (or the Claimant's duly authorized representative) may file
with the Committee a written request for a review of the denial of the claim.
The Claimant (or the Claimant's duly authorized representative):


                                       12



     (a)  may, upon request and free of charge, have reasonable access to, and
          copies of, all documents, records and other information relevant to
          the claim for benefits;

     (b)  may submit written comments or other documents; and/or

     (c)  may request a hearing, which the Committee, in its sole discretion,
          may grant.

     16.04 DECISION ON REVIEW. The Committee shall render its decision on review
promptly, and no later than sixty (60) days after the Committee receives the
Claimant's written request for a review of the denial of the claim. If the
Committee determines that special circumstances require an extension of time for
processing the claim, written notice of the extension shall be furnished to the
Claimant prior to the termination of the initial sixty (60) day period. In no
event shall such extension exceed a period of sixty (60) days from the end of
the initial period. The extension notice shall indicate the special
circumstances requiring an extension of time and the date by which the Committee
expects to render the benefit determination. In rendering its decision, the
Committee shall take into account all comments, documents, records and other
information submitted by the Claimant relating to the claim, without regard to
whether such information was submitted or considered in the initial benefit
determination. The decision must be written in a manner calculated to be
understood by the Claimant, and it must contain:

     (a)  specific reasons for the decision;

     (b)  specific reference(s) to the pertinent Plan provisions upon which the
          decision was based;

     (c)  a statement that the Claimant is entitled to receive, upon request and
          free of charge, reasonable access to and copies of, all documents,
          records and other information relevant to the Claimant s claim for
          benefits; and

     (d)  a statement of the Claimant s right to bring a civil action.

     16.05 LEGAL ACTION. A Claimant s compliance with the foregoing provisions
of this Section 16 is a mandatory prerequisite to a Claimant's right to commence
any legal action with respect to any claim for benefits under this Plan.

     Section 17. NO RIGHTS AS A SHAREHOLDER.

     No Participant shall have any voting or other rights or privileges of a
shareholder of IBT common stock by reason of crediting of stock units to the
Participant's Stock Unit Account.

     Section 18. LEGALITY OF ISSUANCE.

     No shares of IBT common stock shall be issued under this Plan unless and
until IBT has determined that all applicable provisions of state and federal law
have been satisfied.


                                       13



     Section 19. BINDING EFFECT.

     This Plan shall be binding upon and inure to the benefit of the parties to
the Plan and upon the successors and assigns of each Participating Company, and
upon the heirs and legal representatives of the Participant.

     Section 20. INCOMPETENCY.

     If a Participating Company shall find that any person to whom any payment
is payable under this Plan is unable to care for his affairs because of illness
or accident, or is a minor, any payment due (unless a prior claim therefore
shall have been made by a duly appointed guardian, a committee or other legal
representative) may be paid to the spouse, a child, a parent, a brother or
sister, or a custodian determined pursuant to the Uniform Gift to Minors Act, or
to any person deemed by the Participating Company to have incurred expense for
such person otherwise entitled to payment, in such manner and proportions as the
Participating Company may determine. Any such payment shall be a complete
discharge of the liabilities of the Participating Company under this Plan.

     Section 21. SEVERABILITY.

     In the event that any of the provisions of this Plan or portion of the
Plan, are held to be inoperative or invalid by any court of competent
jurisdiction, then: (1) insofar as is reasonable, effect will be given to the
intent manifested in the provision held invalid or inoperative, and (2) the
validity and enforceability of the remaining provisions will not be affected
thereby.

     Section 22. CONSTRUCTION.

     This Plan shall be construed under the laws of the State of Michigan and
Code Section 409A and the Treasury guidance and Regulations promulgated
thereunder. The invalidity or unenforceability of any one or more provision of
the Plan shall not affect the validity or enforceability of the Plan, which
shall remain in full force and effect to the extent permitted by law. If any
provisions of this Plan shall be held illegal or invalid for any reason, said
legality or invalidity shall not affect the remaining parts of this Plan, and
this Plan shall be construed and enforced as if said illegal and invalid
provision had not been included in the Plan.
