                                PRINTRONIX, INC.

                AMENDMENT TO RESTRICTED STOCK PURCHASE AGREEMENT


        This Agreement is made at Irvine, California as of March 26, 1999
between PRINTRONIX, INC., a Delaware corporation (the "Company") and Bruce T.
Coleman (the "Stockholder").

                                    RECITALS

        A.      The Stockholder has acquired shares of the Company (the
"Shares") pursuant to a sale of restricted stock (as that term is used in the
Company's 1994 Stock Incentive Plan) under a restricted stock purchase agreement
(the "Agreement").

        B.      Payment for the Shares was made by promissory note (the "Note")
accompanied by a pledge of the Shares.

        C.      The Company currently has the right to repurchase a portion of
the Shares.

        D.      The parties now desire to amend the Agreement.

        NOW, THEREFORE, the parties hereto amend the Agreement as follows:

                                    AGREEMENT

        1.      Notwithstanding anything in the Agreement to the contrary, the
Company hereby relinquishes any right to repurchase any or all of the Shares and
all such shares are now "vested" as that term is used in the Agreement.

        2.      The parties substitute the promissory note attached hereto as
Exhibit A (the "New Note") in the place of the Note. The Stockholder
acknowledges that the Shares will not be released from the pledge until the New
Note has been paid. Therefore, by virtue of the inability to prepay the New
Note, the Stockholder will be unable to sell the Shares for at least two years.

        3.      The Stockholder shall not voluntarily resign from his position
with the Company for a period of two years from the date hereof. The Stockholder
recognizes that, if he were to terminate the relationship with the Company at a
time when the Company deemed that the continued relationship was in its best
interests, that the Company would be damaged.

        4.      Nothing in this agreement alters the Company's right to
terminate any employment or other relationship with the Stockholder at will,
with or without cause.

        5.      Except as so amended, the Agreement remains in full force and
effect.


                                      -1-

IN WITNESS WHEREOF, this agreement is entered into as of the date first-above
written.

THE COMPANY                                 THE STOCKHOLDER
