     Re:  Stockholders Agreement

Dear Norman:

          This Letter Agreement confirms the understanding reached between you,
Diamond Triumph Auto Glass, Inc., a Delaware corporation (the "Company"), Green
Equity Investors II, L.P. ("GEI"), Kenneth Levine and Richard Rutta regarding
the applicability of that certain Management Subscription and Stockholders
Agreement (the "Stockholders Agreement"), entered into by and among you, the
Company and GEI as of March 31, 1998, with respect to all Restricted Shares (as
defined in that certain Restricted Stock Agreement entered into between you and
the Company dated as of June 1, 2002 (the "Restricted Stock Agreement")).
Capitalized terms used herein without definition shall have the meaning set
forth in the Stockholders Agreement.

          1.     On the date hereof, you will be awarded Restricted Shares
pursuant to the terms and conditions set forth in the Restricted Stock
Agreement.

          2.     You hereby agree, as a condition to receiving the Restricted
Shares, that all Restricted Shares (whether or not vested) shall be deemed to be
"Covered Shares" under the Stockholders Agreement and shall be subject to the
terms and conditions of the Stockholders Agreement (including, without
limitation, the terms and conditions set forth in Sections 3, 4, 5, 6, 7, 8 and
9 thereof) with the same force and effect as if such Restricted Shares were
originally subject thereto; provided, however, that notwithstanding any
provision to the contrary in Section 4 of the Stockholders Agreement, the Call
Closing shall not occur, and the purchase price per share subject to the
Company's "call" option shall not be determined, prior to the expiration of six
months following the date such shares were first transferred to you; and,
provided, further, that notwithstanding any provision to the contrary in Section
7 of the Stockholders Agreement, the "piggyback" registration rights contained
in such Section 7 shall not apply to any Restricted Shares until the first
applicable public offering following the first date on which the Common Stock is
publicly traded on any national securities exchange, or the Nasdaq National
Market System or on the Nasdaq "Small Cap" Issues System; and, provided,
further, that notwithstanding anything in this Letter Agreement or the
Stockholders Agreement to the contrary, no Restricted Shares may be sold,
transferred, assigned, pledged, encumbered or otherwise disposed of by you prior
to the time the Restrictions (as defined in the Restricted Stock Agreement) with
respect to such Restricted Shares have lapsed.

          3.     In order to effectuate the foregoing, you agree to execute any
additional documents as may be reasonably requested from time to time by the
Company or GEI.

          Please indicate your acceptance of the terms and provisions of this
Letter Agreement by signing both copies of this Letter Agreement and returning
one copy to me. The other copy is for your files. This Letter Agreement shall
constitute an amendment to the Stockholders Agreement as described

in Section 12(a) thereof. This Letter Agreement shall be governed and construed
under the internal laws of the State of New York and may be executed in several
counterparts.
