The Board of Directors
Integral Systems, Inc.
6721 Columbia Gateway Drive
Columbia, Maryland 21046

Dear Members of the Board of Directors:

I am writing to you on behalf of Vintage Partners, L.P. (collectively, Vintage
or we), which owns 9.9% of the common stock Integral Systems, Inc. (the Company
or Integral Systems).

We are writing to express our surprise and dismay at the Companys Form 8K
filing on Friday, August 13, 2010 describing the adoption of significant
revisions to the Companys charter documentation and governance provisions.
We believe these revisions serve to disenfranchise the Companys stockholders,
seek to entrench the current Board and management, and are contrary to
principles of good corporate governance.  We believe the Company had made
positive progress with respect to stockholder participation in the governance
of the Company following its 2006 correspondence with Mellon HBV
Alternative Strategies LLC, in keeping with recent market trends. We are
very concerned that the Board appears to have completely undone this progress
by implementing measures which include implementation of a classified board
of directors, increasing the percentage of stockholders required to call a
special meeting to a majority (as opposed to 25%), and providing the Board the
sole power to set the number of directors and fill vacancies that serve only to
limit stockholder participation in the governance of the Company and insulate
the Board.  We were very surprised to see the Board make these significant
governance changes without consulting with, or receiving approval from, the
Companys stockholders.

In addition, as you know, we have made several requests for basic historical
financial information regarding the Company, so that we could provide input (as
requested by you) on the Companys operational efficiency and strategy, and have
offered to enter into a customary nondisclosure agreement regarding this
information.  As you are aware, we believe there are several opportunities to
reduce the Companys operating expenses, which would result in a significant
increase in profitability. These cost reductions would simultaneously
increase Integral Systems chances to win future program awards from an
increasingly cost-focused Department of Defense.

While we originally were assured on several occasions that this information
would be promptly forthcoming and the Company was
interested in working with us to improve its cost structure and ultimately
stockholder value, the Company later changed positions and indicated it
would not share this information with us.

As the Companys largest stockholder, we are very concerned that the Companys
Board is not acting in the best interests of the Companys stockholders, and we
are prepared to take immediate action, if necessary, to preserve stockholder
value.

We urge the Board to immediately repeal these governance changes, or
at a minimum submit them to a binding stockholder vote.  In addition, as we
have previously indicated, we are prepared to work constructively with the
Company to improve stockholder value and encourage the Company to provide us
the necessary information to do so.

Very truly yours,



Brian Kahn
Manager of its General Partner
