AMENDMENT NO. 1 TO EMPLOYMENT AGREEMENT

     THIS AGREEMENT NO. 1 TO EMPLOYMENT AGREEMENT, made as of the 8th day of
May, 1995, by and between STAR GATE TECHNOLOGIES, INC., a Delaware
corporation (the "Company"), and Ray D. Wymer (the "Executive").

                                WITNESSETH:

     Whereas, the parties have entered into an Employment Agreement dated as
of April 13, 1993 (the "Employment Agreement"); and

     Whereas the parties hereto wish to amend the Employment Agreement as set
forth below:

     NOW, THEREFORE, the parties hereto hereby agree as follows:

     1.  AMENDMENT TO EMPLOYMENT AGREEMENT.

         (A)   Section 2.2 of the Employment Agreement is hereby amended in
its entirety to read as follows:

         2.2   BONUS FOR FISCAL 1995.  Executive shall be eligible to receive
     a bonus for fiscal 1995 as follows:

     (a) The target bonus shall be 100% of Executive's base salary for fiscal
         1995. Executive shall be entitled to that bonus amount if the
         objectives set by the budget plan for Digi International Inc. (the
         "Budget Plan" or "Budget") for fiscal 1995 are met.

     (b) If some or all of the objectives of the Budget Plan are not met for
         fiscal 1995, the Board of Directors of Digi will determine in its
         discretion what portion, if any, of the target bonus amount will be
         paid to Executive for that year. If the objectives are exceeded for
         fiscal 1995, the Board may in its discretion award Executive a
         bonus that is larger than the target bonus.

     (c) The bonus for fiscal 1995 shall be paid to Executive on September
         30, 1995 or as soon thereafter as the Company is able to determine
         whether the objectives have been met for that year.

         (B)  Section 2.3 of the Employment Agreement is hereby amended in
its entirety to read as follows:

         2.3  BONUSES BEGINNING IN FISCAL 1996.  Beginning in fiscal 1996, if
     Digi International Inc. meets both net sales and after-tax earnings
     targets set by the Budget Plan by at least 80% for any fiscal year during
     which this Agreement is in effect, then Executive shall be eligible for
     the cash bonuses described below for such year. If the Digi International
     Inc. Budget Plan is less than 80% achieved for either net sales or
     after-tax earnings, neither bonus described below will be paid.

     (a)  If the targets for Digi International Inc. are 100% achieved for
          both net sales and after-tax earnings, Executive shall be entitled



          to a bonus equal to 50% of Executive's base salary. If the Digi
          International Inc. targets for both net sales and after-tax earnings
          are achieved by at least 80%, but for either measure by less than
          100%, Executive will be entitled to a percentage of the foregoing
          bonus amount (i.e., 50% of Executive's base salary) equal to the
          smaller of the percentages of net sales or after-tax earnings that
          were achieved.

     (b)  Provided that the Digi International Inc. targets are at least 80%
          achieved, Executive will also be entitled to an additional bonus
          (the "PMU Bonus") based upon targets for net sales and operating
          income for Digi International Inc.'s Multiuser Product Marketing
          Unit (the "Multiuser PMU").

     (c)  If the Multiuser PMU targets for both net sales and operating
          income are 100% achieved, Executive will be entitled to a PMU
          Bonus equal to 50% of Executive's base salary. If the net sales
          and operating income targets for the Multiuser PMU are both achieved
          by at least 80%, but for either measure by less than 100%, Executive
          will be entitled to a prorated PMU Bonus as set forth below:

          (i)  Three-fourths of the amount of the PMU Bonus will be
               contingent upon operating income. As a result, if the Multiuser
               PMU target for operating income is achieved by at least 80%,
               Executive will be entitled to a percentage of the amount which
               is contingent upon operating income (i.e., three-fourths of
               50% of Executive's base salary) equal to the percentage
               (not exceeding 100%) by which the Multiuser PMU operating income
               was achieved.

          (ii) One quarter of the amount of PMU Bonus will be similarly
               contingent upon net sales. As a result, if the Multiuser PMU
               target for net sales is achieved by at least 80%, Executive
               will be entitled to a percentage of the amount which is
               contingent upon net sales (i.e., one quarter of 50% of
               Executive's base salary) equal to the percentage (not exceeding
               100%) by which the Multiuser PMU target for net sales was
               achieved.

     (d)  If some or all of the objectives of the Budget Plan are exceeded
          for a fiscal year, the Board of Directors of Digi may in its
          discretion award Executive a bonus that is larger than the target
          bonus.

     (e)  The bonuses for each fiscal year shall be paid to Executive on
          September 30 of each year or as soon thereafter as the Company is
          able to determine whether the objectives have been met for that year.

     (f)  The Board of Directors will consult with Executive before
          determining the Budget Plan and Multiuser PMU targets for each fiscal
          year.  However, the Board will have authority to establish

                                    -2-



          the Budget Plan and Multiuser PMU targets for each year in its sole
          discretion.

          (C)  References to "Budget," "Budget Plan" and "Company Budget Plan"
in the remaining provisions of the Employment Agreement shall be deemed to be
references to the budget plan for Digi International Inc., and the references
to the "Company" in Section 3.2(iii) shall be deemed to be a reference to
Digi International Inc.

     2.  EFFECTIVE DATE.  This Amendment No. 1 shall be effective from and
after October 1, 1994.

     3.  NO ADDITIONAL CHANGES.  Except as expressly amended by this
Amendment No. 1, the Employment Agreement shall continue in full force and
effect.

     IN WITNESS WHEREOF, the parties have executed this Amendment No. 1 as of
the date first above written.
