PROXY STATEMENT

General Information

This Proxy Statement is furnished in connection with the solicitation of proxies
by the Board of Directors of IBT Bancorp, Inc. (the Corporation) a Michigan
financial holding company, to be voted at the Annual Meeting of Shareholders of
the Corporation to be held on Tuesday, May 7, 2002 at 7:00 p.m. at The Holiday
Inn, 5665 E. Pickard Street, Mount Pleasant, Michigan, or at any adjournment or
adjournments thereof, for the purposes set forth in the accompanying Notice of
Annual Meeting of Shareholders and in this Proxy Statement.

This Proxy Statement has been mailed on April 12, 2002 to all holders of record
of common stock as of the record date.

Voting at the Meeting

The Board of Directors of the Corporation has fixed the close of business on
April 1, 2002 as the record date for the determination of shareholders entitled
to notice of, and to vote at, the Annual Meeting of Shareholders and any
adjournment thereof. The Corporation has only one class of common stock and no
preferred stock. As of April 1, 2002, there were 4,274,400 shares of common
stock of the Corporation outstanding. Each outstanding share entitles the holder
thereof to one vote on each separate matter presented for vote at the meeting.
If the enclosed proxy is executed and returned, it may be revoked at any time
before it is exercised at the meeting. All shareholders are encouraged to date
and sign the enclosed proxy form, indicate their choice with respect to the
matters to be voted upon, and return it to the Corporation.

Election of Directors

The Board of Directors is divided into three classes, with the directors in each
class being elected for a term of three years. At the Annual Meeting of
Shareholders, three directors will be elected for terms ending with the annual
meeting of shareholders in 2005. Mr. Robert O. Smith is not standing for
reelection in 2002. Mr. Smith retired from the Board of Directors on December
31, 2001.

Except as otherwise specified in the proxy, proxies will be voted for election
of the three nominees named below. If a nominee becomes unable or unwilling to
serve, proxies will be voted for such other person, if any, as shall be
designated by the Board of Directors. However, the Corporation's management now
knows of no reason to anticipate that this will occur. Directors are elected by
a plurality of the votes cast, whether in person or by proxy, by holders of the
Corporation's common stock at the Annual Meeting of Shareholders, provided a
quorum (a majority of the shares entitled to be voted at the Annual Meeting of
Shareholders)

is present or represented. Thus, the three nominees for election as directors
who receive the greatest number of votes cast will be elected directors.
Consequently, shares not voted, whether by withholding of authority or
otherwise, have no effect on the election of directors. If a proxy is returned
for such shares or they are represented in person at the Annual Meeting of
Shareholders, they will be counted toward the establishment of a quorum.

Nominees for reelection and other current directors are listed below. Also shown
for each nominee and each other current director is his principal occupation for
the last five or more years, age and length of service as a director of the
Corporation and the Bank.

The Board of Directors of the Corporation met 13 times during 2001. All
incumbent directors attended 75% or more of the meetings held in 2001. The Board
of Directors has an Audit Committee and a Nominating Committee.

The Audit Committee is composed of independent directors who meet the
requirements for independence as defined in Rule 4200(a)(15) of the National
Association of Securities Dealers' listing standards. Information regarding the
functions performed by the Committee, its membership, and the number of meetings
held during the year, is set forth in the "Report of the Audit Committee"
included elsewhere in this annual proxy statement. The Audit Committee is
governed by a written charter approved by the Board of Directors.

The Corporation has a standing Nominating Committee. The Committee consists of
directors Fabiano, Walldorff and Weburg. Shareholders who wish to recommend

Report of the Audit Committee

The Audit Committee oversees the Corporation's financial reporting process on
behalf of the Board of Directors. The Committee consists of directors
Schumacher, Cassel, Walldorff and Weburg. Management has the primary
responsibility for the financial statements and the reporting process including
the systems of internal controls. In fulfilling its oversight responsibilities,
the Committee reviewed the audited consolidated financial statements in the
Annual Report with management including a discussion of the quality, not just
the acceptability, of the accounting principles, the reasonableness of
significant judgments, and the clarity of disclosures in the consolidated
financial statements.

The Committee reviewed with the independent auditors, who are responsible for
expressing an opinion on the conformity of those audited consolidated financial
statements with auditing principles generally accepted in the United States of
America, their judgments as to the quality, not just the acceptability, of the
Corporation's accounting principles and such other matters as are required to be
discussed with the Committee under SAS 61. In addition, the Committee has
discussed with the independent auditors the auditors' independence from
management and the Corporation including the matters in the written disclosures
required by professional auditing standards and considered the compatibility of
nonaudit services with the auditors' independence.

The Committee discussed with the Corporation's internal and independent auditors
the overall scope and plans for their respective audits. The Committee meets
with the internal and independent auditors, with and without management present,
to discuss the results of their examinations, their evaluations of the
Corporation's internal controls and the overall quality of the Corporation's
financial reporting process. The Committee held six meetings during the fiscal
year 2001, and all directors attended 75% or more of the meetings held in 2001.

In reliance on the reviews and discussions referred to above, the Committee
recommended to the Board of Directors (and the Board has approved) that the
audited consolidated financial statements be included in the Annual Report on
Form 10-K for the year ended December 31, 2001 for filing with the Securities
and Exchange Commission. The Committee and the Board have also approved the
reappointment of the Corporation's independent auditors.

The Defined Benefit Pension Plan

The Corporation sponsors a defined benefit pension plan. This plan was
originally adopted in 1973 and was substantially revised in 1989. Only employees
who have attained the age of 21 and who have worked more than 1000 hours in the
current plan year are eligible to participate.

Annual contributions are made to the plan as required by accepted actuarial
principles, applicable federal tax law, and expenses of operating and
maintaining the plan. The amount of contributions on behalf of any one
participant cannot be separately or individually computed.

Pension plan benefits are based on an average of a participant's five highest
years of compensation. A participant may earn a benefit for up to 35 years of
accredited service. Earned benefits are 100 percent vested after five years of
service. Benefit payments normally start when a participant reaches age 65. A
participant with more than five years of service may elect to take early
retirement benefits anytime after reaching age 55. Benefits payable under early
retirement are reduced actuarially for each month prior to age 65 in which
benefits begin.

The following table indicates estimated annual benefits payable upon normal
retirement for various compensation levels and years of service. Additional
benefits may be earned due to integration of social security benefits. The
amounts that may be earned are undeterminable until retirement.

Five Year
Average Years of Accredited Service
of Highest
Compensation 5 15 25 35
------------ --------- ---------- --------- ---------

$20,000 $ 900 $ 2,700 $ 4,500 $ 6,300
50,000 2,250 6,750 11,250 15,750
75,000 3,375 10,125 16,875 23,625
100,000 4,500 13,500 22,500 31,500
125,000 5,625 16,875 28,125 39,375
150,000 6,750 20,250 33,750 47,750
200,000 7,875 23,625 39,375 56,125

The amounts calculated under the plan's benefit formula assume a monthly payment
for life. A married participant will generally receive an actuarially reduced
monthly payment because the participant's surviving spouse will also receive
monthly payments for life after the participant's death. As of December 31,
2001, David W. Hole had 42 years, Richard J. Barz had 29 years, Dennis P. Angner
had 18 years, and Herbert C. Wybenga had one year of credited service under the
plan.

Report on Executive Compensation

In 2001, all executive officers of the Corporation were also officers of one of
the Corporation's subsidiaries. Their service as officers of the Corporation is
generally incidental to their primary service as an officer of a subsidiary. The
executive officers of the Corporation, except for those who are entitled to
director fees, receive no compensation directly from the Corporation. Except for
the President of each subsidiary, the Corporation has delegated the authority
and responsibility for the setting of compensation to the Board of Directors of
each subsidiary. The compensation for the President of each subsidiary is
reviewed and approved by the Corporation's Board of Directors based on
recommendations from each subsidiary's Board of Directors.

The entire Board of Directors of the Corporation serves as a compensation
committee with Hole and Wybenga excused from the meetings where decisions with
respect to their own compensation are made. The Board of Directors has the
responsibility for establishing all formal employee benefit plans offered to
subsidiary employees.

The Board's approach to determining the annual salary of executive officers is
to offer competitive salaries in comparison with market practices. The Board
utilizes regional and national compensation surveys which provide salary ranges
for banks of similar size. Based on these surveys, the Board establishes salary
ranges for all job classifications. Factors used to decide where an executive
officer salary should be within the established range include the historical
financial performance, financial performance outlook, years of service, and job
performance. The salary paid to Hole and Wybenga was in the 50th to 75th
percentile in 2001 and 2000, and in the 25th to 50th percentile in 1999 of the
comparison group. The Board's primary consideration in where Hole and Wybenga's
salaries fit within the defined range was

their years of service as President and CEO and the Corporation exceeding its
financial performance goals.

Dennis P. Angner Ronald E. Schumacher

David W. Hole Herbert C. Wybenga
L. A. Johns

Compensation Committee Interlocks and Insider Participation

The entire Board of Directors serves as a Compensation Committee. Director Hole
was President and CEO of the Corporation and Isabella Bank and Trust during
2001, and Director Wybenga is Chairman, President and CEO of Farmers State Bank.
Neither Hole nor Wybenga participated in any of the procedures which pertain to
their compensation or other related matters and they are excused from the
meetings at such times. Director Angner's compensation is set by Isabella Bank
and Trust. Mr. Angner is not a member of Isabella Bank and Trust's Board of
Directors and does not participate in the setting of his compensation.

Remuneration of Directors

The Corporation paid $600 per board meeting to its directors during 2001 and
$175 per committee meeting attended. Directors of Isabella Bank and Trust are
paid $700 per board meeting and $175 per committee meeting they attend. Farmers
State Bank paid a retainer of $2,000, $400 per board meeting, and $100 per
committee meeting they attended (provided the committee meeting was on a
non-board meeting day). Directors who are officers of a subsidiary are not paid
for attendance at committee meetings.

The Corporation sponsors a deferred compensation plan for directors (the
Directors' Plan). The Directors' Plan was adopted in 1984 and was substantially
revised in 1989 and 1996. Under the Directors' Plan, deferred directors' fees
are converted on a quarterly basis into stock units of the Corporation's common
stock. The fees are converted based on the purchase price for a share of the
Corporation's common stock under the Corporation's Dividend Reinvestment Plan.

Pursuant to the terms of the Directors' Plan, directors of the Corporation and
its subsidiaries are required to defer at least 25% of their earned board fees.
The amount deferred under the terms of the plan in 2001 was $311,000, resulting
in 11,312 stock units being credited to participants' accounts. As of December
31, 2001, there were 108,667 stock units credited to participants' accounts.
Stock units credited to a participant's account are eligible for cash and stock
dividends as payable. All amounts deferred are unsecured claims against the
Bank's general assets. The net cost of this benefit to the Corporation was
$63,000 in 2001.

Distribution from the Directors' Plan occurs when the participant terminates
service with the Bank and/or attains age 65. Distributions may take the form of
shares of Corporation common stock equal to the number of stock units credited
to the participant's account, cash equal to the value of the stock units on the
date of distribution, or a combination of stock and cash. Any Corporation common
stock issued under the Directors' Plan will be considered restricted stock under
the Securities Act of 1933, as amended.

Indebtedness of and Transactions with Management

Certain directors and officers of the Corporation and members of their families
were loan customers of the subsidiary banks, or have been directors or officers
of corporations, or partners of partnerships which have had transactions with
the subsidiary banks. In management's opinion, all such transactions are made in
the ordinary course of business and are essentially on the same terms, including
collateral and interest rates, as those prevailing at the same time for similar
transactions with other customers. These transactions do not involve more than a
normal credit risk. Total loans to these customers were $9,549,000 as of
December 31, 2001.

Stock Performance

The graph on the following page compares the cumulative total shareholder return
on Corporation Common Stock for the last five years with the cumulative total
return on (1) the NASDAQ Stock Market Index, which is comprised of all United
States common shares traded on the NASDAQ and (2) the NASDAQ Bank Stock Index,
which is comprised of bank and bank holding company common shares traded on the
NASDAQ over the same period. The graph assumes the value of an investment in the
Corporation and each index was $100 at January 1, 1997 and all dividends are
reinvested.

As to Other Business Which May Come Before the Meeting

Management of the Corporation does not intend to bring any other business before
the meeting for action. However, if any other business should be presented for
action, it is the intention of the persons named in the enclosed form of proxy
to vote in accordance with their judgment on such business.

Relationship with Independent Accountants

The Board of Directors has reappointed Rehmann Robson, P.C. as independent
auditors of the Corporation for the year ending December 31, 2002.

A representative of Rehmann Robson, P.C., is expected to be present at the
Annual Meeting of Shareholders to respond to appropriate questions from
shareholders and to make any comments they believe appropriate.

Audit Fees
The aggregate fees billed by Rehmann Robson, P.C. for professional services
rendered for the audit of the Corporation's consolidated financial statements
for 2001 and the review of the financial statements included in the
Corporation's quarterly Form 10-Q filings were $53,500.

Financial Information Systems Design and Implementation Fees
For the year 2001, Rehmann Robson did not render to the Corporation professional
services for financial information systems design and implementation.

All Other Fees
The aggregate fees billed by Rehmann Robson, P.C. to the Corporation and its
subsidiaries in 2001 for other audit related services were $15,000 and for
nonaudit related services were $49,000.

The Audit Committee considered whether the provisions of the nonaudit related
services listed under "All Other Fees" above were compatible with maintaining
Rehmann Robson, P.C.'s independence.

Shareholder Proposals

Any proposals which shareholders of the Corporation intend to present at the
next annual meeting of the Corporation must be received before December 12, 2002
to be considered for inclusion in the Corporation's proxy statement and proxy
form for that meeting. Proposals should be made in accordance with Securities
and Exchange Commission Rule 14a-8.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Corporation's
directors and certain officers and persons who own more than ten percent of the
Corporation's common stock, to file with the SEC initial reports of ownership
and reports of changes in ownership of the Corporation's common stock. These
officers, directors, and greater than ten percent shareholders are required by
SEC regulation to furnish the Corporation with copies of these reports.

To the Corporation's knowledge, based solely on review of the copies of such
