           IRWIN BANK & TRUST COMPANY FILES ARTICLES OF AMENDMENT WITH
               PENNSYLVANIA DEPARTMENT OF BANKING FOR NAME CHANGE

IRWIN,  PENNSYLVANIA,  MARCH 16, 2007 (AMEX:IRW):  Irwin Bank & Trust Company, a
wholly owned subsidiary of IBT Bancorp, Inc. announces that it filed Articles of
Amendment  with the  Pennsylvania  Department  of Banking on or about  March 12,
2007.  The purpose of said amendment is to change the name of Irwin Bank & Trust
Company to Irwin Bank.

Mr. Urtin,  President/CEO  stated, "In 2006, Irwin Bank's Management Team took a
long hard look at  ourselves  to determine if the way we see the Bank - and more
importantly,  the way customers see us - accurately portrays who we are, what we
offer,  and what  makes  us  unique  and a  better  choice  for  banking  in our
community. We also realized that we had to put forth more of an effort to better
serve our customers if we intended to continue to grow and succeed.  We realized
we needed to evolve,  just as the banking  industry  was  evolving - to find new
ways to deliver  the best  possible  products  and  services  to our  customers.
Realizing that we needed expert advice and counsel to set the benchmark for this
"new" position and culture,  Irwin Bank engaged a team of "branding" specialists
to research our market, customer base, banking operations, and our needs for the
future.  After long and hard work,  they  provided a number of  recommendations,
including dropping "Trust Company" after the Irwin Bank name.  Research findings
showed us that  majority of  customers  referred  to us as "Irwin  Bank" and not
"Irwin  Bank &  Trust  Company."  With  that  in  mind,  we put  together  a new
advertising campaign to get the "New" Brand out to the public. Although our name
has changed, Irwin Bank's commitment to its customers has remained the same."

Irwin Bank (the "Bank")  provides a full range of commercial  and retail banking
services.  Irwin Bank was incorporated in 1922 under the laws of Pennsylvania as
a  commercial  bank under the name  "Irwin  Savings & Trust  Company."  The Bank
engages in a full service mortgage, commercial and consumer banking business, as
well as trust and a variety of deposit services  provided to its customers.  The
Bank operates through its main office, six branch offices, two loan centers, and
a trust office as well as through three  supermarket  branches.  The Bank's main
office, full service branch offices, loan centers,  trust office and supermarket
branches are located in the Pennsylvania counties of Westmoreland and Allegheny.
