                        REAFFIRMATION OF VOTING AGREEMENT


         This REAFFIRMATION OF VOTING AGREEMENT, dated as of January 10, 2000
(this "Agreement"), reaffirms the Voting Agreement, dated as of September 15,
1999, by and among Photronics, Inc., a Connecticut corporation ("Parent") and
the other parties listed on the signature page thereof (collectively, the
"Shareholder"), as amended by that certain Amended and Restated Voting
Agreement, dated as of October 26, 1999 among Parent and the other parties
listed on the signature page hereof (the "Voting Agreement").

         WHEREAS, simultaneously with the execution of the Voting Agreement,
Parent, Al Acquisition Corp. ("Merger Sub") and Align-Rite International, Inc.
(the "Company") entered into an Agreement and Plan of Merger (the "Merger
Agreement") providing for, among other things, the merger of Merger Sub with and
into the Company (the "Merger");

         WHEREAS, the parties intend concurrently with the execution of this
Agreement to execute Amendment No.1 ("Amendment No. 1") to the Merger Agreement
in order to provide for certain changes to the terms and conditions thereof.

         WHEREAS, the parties to the Voting Agreement now desire to reaffirm the
Voting Agreement;

         WHEREAS, as of the date hereof, the Shareholder is the beneficial owner
of the number of shares (the "Shares") of common stock, par value $.01 per
share, of the Company set forth opposite such Shareholder's name on Schedule 1
attached hereto. Except as specified herein, terms defined in the Merger
Agreement are used herein as defined therein.

         NOW THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, the parties hereto agree as follows:

         1.       Reaffirmation of Voting Agreement.

                  1.1      Supplement.   Section 1 of the Voting Agreement is

                  1.2      Reaffirmation. The Shareholder reaffirms the Voting
Agreement in its entirety.

2.       Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

3.       Governing Law. This Agreement shall be governed in all respects,
including validity, interpretation and effect, by the laws of the State of
California (without giving effect to the provisions thereof relating to
conflicts of law).

4.       Public Announcements. Shareholder shall not issue any press release or
other statement with respect to the transactions contemplated by this Agreement
and the Merger Agreement, as amended by Amendment No. 1 without the prior
written consent of Parent.

5.       Severability. Any term or provision of this Agreement which is invalid
or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms of
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

6.       Shareholder Capacity. James L. MacDonald makes no agreement or
understanding herein in his capacity as a director or officer of the Company.
The Shareholder signs solely in its capacity as the record holder and beneficial
owner of the Shares and nothing herein shall restrict James L. MacDonald in the
exercise of his fiduciary duties as a director or officer of the Company.

7.       Voting Agreement Confirmed. The Voting Agreement shall remain in full
force and effect.
