                               IBT BANCORP, INC.
                      STOCKHOLDER DIVIDEND REINVESTMENT AND
                          EMPLOYEE STOCK PURCHASE PLAN


                              ARTICLE I. - PURPOSE


                   Effective February 19, 1991, IBT Bancorp, Inc. adopted the
IBT Bancorp, Inc. Stockholder Dividend Reinvestment and Employee Stock Purchase
Plan to provide a simple, systematic and convenient method of acquiring shares
of Common Stock of the Company, without payment of any brokerage commission,
service charge or other expenses. Participants also avoid the necessity of safe
keeping their certificates, for shares of Common Stock credited to their Plan
Accounts. The Plan has been amended and restated and the Company has adopted the
amended and restated Plan effective as of April 29, 2003.

                   The shares of Common Stock acquired under the Plan will be
purchased from the Company. The net proceeds received therefrom will be added to
the working capital of the Company and will be used for general corporate
purposes.

              ARTICLE III. - PARTICIPATION BY DIVIDEND REINVESTMENT

                  3.1 Enrollment: A Stockholder who was participating in the
Plan as of the Effective Date shall continue to participate in the Plan. Any
other Stockholder may enroll in the Plan's Dividend Reinvestment feature at any
time after the Effective Date by completing an Authorization Card and returning
it to the Plan Administrator. Authorization Cards may be obtained by writing the
Plan Administrator at the Company's address.

                  3.2 Commencement: Reinvestment of dividends in Common Stock
shall commence with the next dividend payment after receipt of the Authorization
Card by the Plan Administrator, provided it is received by the Plan
Administrator on or before the record date for that dividend; otherwise,
reinvestment of dividends shall be delayed until the next dividend payment.

                  3.3 Investment Option: The Authorization Card shall provide
for the purchase of additional shares of Common Stock through the following
investment options:

                           (a) Full Dividend Reinvestment. Full dividend
reinvestment directs the Company to pay to the Plan Administrator all of the
Participant's cash dividends on all of the shares of Common Stock then or
subsequently registered in the Participant's name; or

                           (b) Partial Dividend Reinvestment. Partial dividend
reinvestment directs the Company to pay to the Plan Administrator the
Participant's




cash dividends on that number of shares of Common Stock designated in the
appropriate space of the Authorization Card and permits the Participant to
continue to receive cash dividends on the balance of the shares of Common Stock
registered in the Participant's name.

                  In the event a Participant elects Partial Dividend
Reinvestment, the Company is authorized to issue to the Participant separate
stock certificates, one representing shares designated for participation under
the Plan and another representing shares excluded from the Plan.

                  A Participant may select only one of the above options. In all
cases, cash dividends on shares of Common Stock credited to a Participant's Plan
Account shall be reinvested in accordance with the Plan.

                  3.4 Dividend Reinvestment: On each Investment Date a
Participant's full or partial cash dividend shall be remitted by the Company to
the Plan Administrator. The Plan Administrator shall reinvest that dividend, as
well as the full cash dividend on shares of Common Stock credited to the
Participant's Plan Account, in shares of Common Stock purchased directly from
the Company, and shall credit whole and fractional shares to the Participant's
Plan Account (computed to three decimal places). A fractional share of Common
Stock shall earn a proportionate share of future dividends. Such purchases shall
be made by the Plan Administrator promptly (no later than within 30 days of the
receipt), except where curtailment or suspension of purchases is necessary to
comply with applicable provisions of federal or state laws.




                  3.5 Amendment of Investment Option. A Participant may amend
his or her investment option at any time by giving written notice to the Plan
Administrator at the Company's address. Any amendment to a Participant's
investment option shall be effective as of the record date coinciding with, or
next following, the date the amendment is received by the Plan Administrator.

                  3.6 Withdrawal of Dividend Reinvestment Enrollment. A
Participant may withdraw from the Plan's Dividend Reinvestment feature at any
time by giving written notice to the Plan Administrator at the Company's
address. If the request to withdraw is received by the Plan Administrator on or
after the record date for a dividend payment, any dividend paid on the
Investment Date shall be invested for the Participant's Plan Account. The
request shall be processed as promptly as possible by the Plan Administrator
following such Investment Date.

                  As soon as practicable following withdrawal, the Plan
Administrator shall send the Participant at no charge, a certificate in the
Participant's name, for the whole shares of Common Stock in the Participant's
Plan Account and a cash payment shall be made for any fraction of a share.

                  Notwithstanding anything in this Section 3.6 to the contrary,
if the Participant so requests, the Plan Administrator shall sell such whole
shares of Common Stock and remit to the Participant the proceeds, less any
related brokerage commission and applicable stock transfer tax.



                  3.7 Disposition of all Shares: If a Participant disposes of
all shares of Common Stock registered in the Participant's name, the Plan
Administrator shall continue to reinvest the dividends on the shares credited to
the Participant's Plan Account until otherwise notified.

                  3.8 Accrued Shares: A Participant in the Plan's Dividend
Reinvestment feature may deposit certificates for Common Stock now or hereafter
registered in the Participant's name for credit in his or her Plan Account as
accrued shares under the Plan. Such certificates shall be transferred to the
Plan Administrator or its agent as agent for the Participant. This service shall
be provided at no charge to the Participant.

              ARTICLE IV. - PARTICIPATION BY COMPENSATION DEDUCTION

                  4.1 Enrollment: An Employee who was participating in the Plan
as of the Effective Date shall continue to participate in the Plan. Any other
Employee may enroll in the Plan's compensation deduction feature at any time
after the Effective Date by completing an Authorization Card and returning it to
the Plan Administrator. Authorization Cards may be obtained by contacting the
Company's Secretary.

                  4.2 Commencement of Deductions: The deduction of amounts from
the Participant's compensation (for purposes hereof "compensation" shall also
include board director fees) shall commence with the Participant's next regular
compensation check following receipt by the Plan Administrator of the completed
Authorization Card, if the Authorization Card is received by the Plan
Administrator not less than 96 hours before compensation checks are distributed.




                  4.3 Investment Options: The Authorization Card shall provide
for the deduction from the Participant's compensation on a bi-weekly basis (or
such other basis determined by the Company's Board of Directors) based on a
minimum and maximum amount set by the Company's Board of Directors from
time-to-time.

                  4.4 Purchase of Common Stock: Amounts deducted from a
Participant's compensation shall be remitted by the Employer to the Plan
Administrator who shall invest said amounts in shares of Common Stock purchased
directly from the Company. Such purchases shall be made no later than the first
work day of the month following the month in which said amounts were deducted,
except where curtailment or suspension of purchases is necessary to comply with
applicable provisions of federal or state laws.

                  4.5 Amendment of Compensation Deduction: A Participant may
amend his or her compensation deduction election at any time by giving written
notice to the Plan Administrator. Any amendment to a Participant's compensation
deduction election shall be effective as of the Participant's next regular
compensation check if the written notice is received by the Plan Administrator
not less than 96 hours before compensation checks are distributed.

                  4.6 Withdrawal of Compensation Deduction Enrollment: A
Participant may withdraw from the Plan's compensation deduction feature at any
time by giving written notice to the Plan Administrator. Any request to withdraw
shall be effective as of the Participant's next regular compensation check if
the notice to withdraw is received




by the Employer not less than 96 hours before compensation checks are
distributed. A Participant who withdraws from the Plan's compensation deduction
feature may not reparticipate in the Plan until one year has elapsed from the
date the Plan Administrator receives the withdrawal notice.

                  As soon as practicable following withdrawal, the Plan
Administrator shall send the Participant at no charge, a certificate in the
Participant's name, for the whole shares of Common Stock in the Participant's
Plan account and a cash payment shall be made for any fraction of a share.

                  Notwithstanding anything in this Section 4.6 to the contrary,
if the Participant so requests, the Plan Administrator shall sell such whole
shares of Common Stock and remit to the Participant the proceeds, less any
related brokerage commission and applicable stock transfer tax.

                  4.7 Automatic Dividend Reinvestment: All shares purchased for
the Participant pursuant to the Plan's compensation deduction feature shall be
credited to the Participant's Plan Account and will automatically participate
in, and be governed by, the terms and conditions of the Plan's Dividend
Reinvestment feature (as set forth in Article III above).

                           ARTICLE V. - PLAN OPERATION

                  5.1 Per-Share Price of Common Stock: The per-share price of
shares of Common Stock purchased from the Company under the Plan shall be
determined by the Board of Directors of the Company. In making the
determination, the Board of




Directors will consider the financial condition of the Company and its recent
operating results, values of publicly traded securities of other financial
institutions giving effect to the relative book values and earnings of such
institutions and the lack of liquidity of the Common Stock, and such other
factors as the Board in its sole and absolute discretion deems relevant.

                  5.2 Price of any Fraction of a Share: Whenever, pursuant to
the terms of the Plan, a Participant receives cash for any fraction of a share
of the Common Stock, said cash payment shall be determined on the basis of the
most recent per-share price for shares of Common Stock purchased from the
Company under the Plan.

                  5.3 Commingling of Monies: In making purchases for
Participant's Plan Accounts, the Plan Administrator may commingle the
Participant's dividends and compensation deductions with those of others
participating in the Plan. It is understood that any monies held under the Plan
will not bear interest.

                  5.4 Issuance of Stock Certificates:

                           (a) Registration of Certificates. Certificates for
shares of Common Stock purchased for a Participant shall be registered in the
name of the Plan Administrator or its agent and, except as provided in (b)
below, shall not be issued in the Participant's name while the Participant is
enrolled in the Plan.

                           (b) Reissuance in Participant's Name. A Participant
in the Plan's Dividend Reinvestment feature who desires to continue enrollment
in the Plan, but elects to have the whole shares of Common Stock credited to the
Participant's Plan




Account reissued in the Participant's name, can do so at no charge upon written
request to the Plan Administrator. Certificates for fractional shares of Common
Stock shall not be issued under any circumstances. A Participant in the Plan's
compensation deduction feature may elect to receive a distribution of whole
shares of Common Stock under the Plan only if he or she withdraws from Plan
participation in accordance with Section 4.6.

                  If the request to have whole shares of Common Stock reissued
in the Participant's name is received by the Plan Administrator on or after the
record date for a dividend payment, any dividend paid on the aforementioned
whole shares on the Investment Date shall be invested for the Participant's Plan
Account. The request shall be processed as promptly as possible by the Plan
Administrator following such Investment Date.

                  5.5 Costs to Participants: The Participant shall incur no
costs for purchases of Common Stock by the Plan Administrator. However, if at
the time of termination of Plan participation a Participant directs the Plan
Administrator to sell shares of Common Stock credited to the Participant's Plan
Account, the Participant shall pay any related brokerage commission and
applicable stock transfer tax. Service charges, such as administration fees if
the Plan should be administered by someone other than the Company, are the
responsibility of the Company.





                  5.6 Reports to Participants:

                           (a) Purchase Reports. As soon as practicable
following each purchase of shares of Common Stock for a Participant, the
Participant shall receive a statement showing the amount invested, purchase
price, the number of shares purchased, total shares accumulated, and other
relevant information for the year to date.

                           (b) Other Reports. Each Participant shall receive
copies of the same communications sent to all other holders of shares of Common
Stock, including the Company's quarterly reports and annual report to
shareholders, a notice of the annual meeting and proxy statement and (if
necessary) Internal Revenue Service information (on Form 1099) for reporting
dividend income received.

                           (c) Address. All notices, statements, and reports
from the Plan Administrator to a Participant shall be addressed to the
Participant at his or her last address of record with the Plan Administrator.
The Participant agrees to notify the Plan Administrator promptly in writing of
any change of address.

                  5.7 Termination of Participant's Plan Account: The Company may
terminate a Participant's Plan Account at any time in its discretion by giving
written notice to the Participant. As soon as practicable following termination,
the Plan Administrator shall send the Participant a certificate in the
Participant's name, for the whole shares of Common Stock in the Participant's
Plan Account and a cash payment shall be made for any fraction of a share.




                  Notwithstanding anything in the preceding paragraph to the
contrary, if the Participant so requests, the Plan Administrator shall sell such
whole shares of Common Stock and remit to the Participant the proceeds, less any
related brokerage commission and applicable state transfer tax.

                  5.8 Termination of the Plan:

                  In the event the Company should terminate the Plan, as soon as
practicable following termination, the Plan Administrator shall send each
Participant a certificate in the Participant's name, for the whole shares of
Common Stock in the Participant's Plan Account and a cash payment shall be made
for any fraction of a share.

                  Notwithstanding anything in the preceding paragraph to the
contrary, if the Participant so requests, the Plan Administrator shall sell such
whole shares of Common Stock and remit to the Participant the proceeds, less any
related brokerage commission and applicable stock transfer tax.

                          ARTICLE VI. - ADMINISTRATION

                  6.1 Appointment of Plan Administrator: The Plan shall be
administered by the Plan Administrator which shall be the Company, a committee
designated by the Board of Directors of the Company, or any entity and its
agents, chosen by the Company to administer the Plan.

                  6.2 Duties of Plan Administrator: The Plan Administrator shall
administer the Plan, keep records, send statements of account activity and other




required reports to Participants, and perform any other duties related to the
Plan. Shares of Common Stock purchased under the Plan and held by the Plan
Administrator shall be registered in its name or the name of its agent
designated for that purpose, as agent for each Participant in the Plan.

                  6.3 Resignation of Plan Administrator: Should the Plan
Administrator resign or otherwise cease to act as agent for the Participants,
the Company shall make other arrangements as it deems appropriate for the
administration of the Plan.

                  6.4 Liability of the Company and the Plan Administrator:
Neither the Company, the Plan Administrator, nor any agent employed by the Plan
Administrator shall be liable in administering the Plan or any act done in good
faith, or for any good faith omission to act, including, without limitation, any
claims of liability:

                           (a) arising out of failure to terminate the
Participant's Plan Account upon such Participant's death prior to receipt of
notice in writing of such death;

                           (b) with respect to the prices at which shares of
Common Stock are purchased or sold for the Participant's Plan Account or the
time when such purchases or sales are made (provided, however that nothing
herein shall be deemed to constitute a waiver of any rights that a Participant
might have under the Securities Exchange Act of 1934 or applicable federal and
state securities laws); and

                           (c) for any fluctuations in the market price after
purchase or sale of shares of Common Stock.




                          ARTICLE VII. - MISCELLANEOUS

                  7.1 Non-Guarantee of Profit: Nothing contained herein, shall
be construed as an assurance by the Company of a profit to the Participant or
protection against loss on shares of the Common Stock purchased under the Plan.

                  7.2 Other Services: The Plan Administrator may charge the
Participant for services performed at the request of a Participant and not
provided for herein.

                  7.3 Pledging of Common Stock: Shares of Common Stock credited
to the Participant's Plan Account under the Plan may not be pledged. A
Participant who wishes to pledge such shares must request that certificates for
such shares be issued in the Participant's name.

                  7.4 Voting of Shares: For each meeting of shareholders, a
Participant shall receive proxy material that will enable the Participant to
vote both the shares of Common Stock registered in the Participant's name
directly and/or whole shares of Common Stock credited to the Participant's Plan
Account. Participants will not be permitted to vote fractional shares of Common
Stock.

                  7.5 Income Tax: It is understood by the Participant that the
reinvestment of dividends and/or the reduction in a Participant's compensation
does not relieve the Participant of any income tax and applicable payroll taxes
which may be payable. The Company shall not withhold taxes from dividends,
unless the Internal Revenue Service directs the Company to withhold 20% of any
dividend payment to




specified Participants who under-report dividend income. In such a situation,
the amount withheld shall not be reinvested under the Plan.

                  7.6 Stock Dividends and Related Matters: Stock dividends in
the form of Common Stock or stock splits distributed by the Company on shares of
Common Stock held by the Plan Administrator for a Participant shall be credited
to the Participant's Plan Account. Certificates for such stock dividends and
stock splits distributed on shares of Common Stock registered in the name of the
Participant shall be mailed directly to the Participant. In the event of a
subscription rights offering or a dividend in the form of a stock other than
Common Stock, such rights or other stock shall be mailed directly to a
Participant in the Plan in the same manner as to holders of Common Stock not
participating in the Plan.

                  7.7 Suspension, Modification, or Termination of the Plan:
Notwithstanding anything herein to the contrary, the Company reserves the right
to interpret and regulate the Plan as it deems desirable or necessary. The
Company reserves the right to suspend, modify or terminate the Plan at any time,
but such action shall have no retroactive effect that would prejudice the
interests of Participants. Notice of any such suspension, modification, or
termination shall be sent to all Participants.

                  7.8 Governing Law: The terms and conditions of this Plan, the
Authorization Card signed by the Participant (which is deemed a part of this
Plan), and the Plan's operation shall be governed by and construed in accordance
with the laws of the State of Michigan and the rules of the Securities and
Exchange Commission.

                  Dated this 29th day of April, 2003.
