EXHIBIT 99.1

                        AMENDMENT TO EMPLOYMENT AGREEMENT
                        ---------------------------------

     THIS AMENDMENT (the "Amendment") to that certain Employment Agreement dated
as of June 24, 2004 (the "Agreement") is made and entered into as of the 8th day
of August, 2006 by and between Concurrent Computer Corporation (the "Company")
and T. Gary Trimm (the "Employee").


     WHEREAS, the Company, through its Board of Directors, and the Employee,
desire to amend the terms and conditions set forth in the Agreement to define
the payments to be made to the employee upon termination of employment;


     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, and for other good and valuable consideration, the parties
agree as follows:

     1.   Amendment
          ---------

          a.   The entire third paragraph of Section 5.4 regarding benefit
          coverage following termination is replaced with the following
          paragraph:

               During the period beginning with the Employee's termination and
               continuing through which time the employee reaches age 65, the
               Company will use its reasonable best efforts to continue the
               Employee's eligibility under its group life insurance,
               hospitalization, medical and dental plans ("Benefits"). To the
               extent Employee is not eligible under the terms of one or more of
               such plans and programs, the Company will provide the Employee
               with the Economic Equivalent for the period through the employee
               reaching age 65. For the purpose of this paragraph, "Economic
               Equivalent" shall mean the amount the Company would have paid for
               such coverage for each employee covered if the Company could
               purchase such coverage or add the Employee to the Company's
               plans. In order to obtain the Benefits, the Employee will have to
               pay the amount that would be the Employee's responsibility if he
               was still employed. The amount paid to the Employee as the
               Economic Equivalent, less the amount of the premium payment which
               is the Employee's responsibility in accordance with the Company
               benefit plan, will be "grossed-up", if taxable (that is, the
               amount necessary to make the Employee whole after taking into
               account (i) the cost of the benefit and (ii) additional income
               taxes, if any, incurred by the Employee on amounts paid to him
               pursuant to this paragraph). Should the Employee find employment
               with another employer ("New Employer") that typically provides
               Benefits to its employees, the Company will cease providing
               Benefits or the Economic Equivalent. If the Employee ceases
               employment with the New Employer and has no Benefits or Economic
               Equivalent from the New Employer, the Employee must immediately
               notify the Company and the Company shall again provide Benefits
               or the Economic Equivalent until the Employee reaches age 65.

     2.   Miscellaneous
          -------------

          a.   This Amendment shall be construed in accordance with the laws of
          the State of Georgia.

          b.   Except as amended hereby, the terms and conditions of the
          Agreement shall remain in effect.

       IN WITNESS WHEREOF, the Company and the Employee have caused this
          Amendment to be executed as of the date first above written.
