Attn: John Donlon

Dear Mr. Donlon:

As you know, there has been some discussion about whether or not Global Access 
Telecommunication Services, Inc. ("Global") is required to obtain the consent 
(the "Consents") of either The Associated Press ("AP") or Hughes Communications 
Galaxy, Inc. ("Hughes") for the sublease to Four Media Company ("4MC") of 
transponder 5 and 7 on Hughes' Galaxy IV satellite which are being subleased to 
Global Access by AP and to AP by Hughes. While we do not necessarily believe the
Consents are required, we are nonetheless in the process of obtaining them at 
this time and agree to use our best efforts to secure the Consents as soon as 
possible.

However, since the obtaining of the Consents may be a time-consuming process and
it is in both Global's and 4MC's interest to expedite the implementation of the 
satellite services contemplated by the agreements between Global and 4MC, Global
is proposing to amend the two agreements between Global and 4MC as set forth 
below.

Therefore, this letter shall serve to amend the Satellite Services Agreement 
between Global and 4MC dated April 12, 1996 for Transponder 5 on Hughes' Galaxy 
IV satellite ("Agreement #1"), and the Satellite Services Agreement between 
Global and 4MC dated April 12, 1996 for Transponder 7 on Hughes' Galaxy IV 
satellite ("Agreement #2"), as follows:

     1. The following shall be added to the Agreement #1 as Section 10, and to 
        Agreement #2 as Section 11:

            "INDEMNIFICATION. Global agrees to indemnify and hold 4MC, its
             ----------------
            directors, officers, employees, contractors, subcontractors, and
            agents (collectively, the "4MC Indemnitees") harmless from, against
            and with respect to any and all claims, damages, liabilities, costs
            and expense (including reasonable attorneys fees) up to a limit of
            an aggregate of $1,000,000 which are incurred in connection with any
            claim against any of the 4MC Indemnities arising out of Global's
            failure to obtain the Consents or establish with Hughes and AP that
            such Consents are not required for the sublease of the Transponder
            to 4MC. This indemnification will survive the obtaining of the
            Consents by one (1) year, and shall thereafter be of no further
            force and effect."

     2. The following shall be added to Agreement #1 as Section 11:

            "11. PREEMPTION. Should AP exercise it rights to preempt Global's
                 -----------
            use of the Transponder pursuant to Paragraph 8.02(b) of the
            Transponder Lease Agreement between AP and Global, dated as of July
            6, 1995, Global agrees to provided to 4MC full-time use of
            Transponder 11 on Galaxy IV, or another transponder acceptable to
            both Global and 4MC (the "Replacement Transponder") for 4MC's use
            pursuant to the terms of the Agreement between Global and 4MC."

     3. The following shall be added to Agreement #2 as Section 12:

            "12. PREEMPTION. Should AP exercise its right to preempt Global's
                 ----------- 
            use of the Transponder pursuant to Paragraphs 8.02(b) of the
            Transponder Lease Agreement between AP and Global, dated as of July
            6, 1996, Global agrees to provide to 4MC full-time use of
            Transponder 9 on Galaxy IV, or another transponder acceptable to
            both Global and 4MC (the "Replacement Transponder") for 4MC's use
            pursuant to the terms of the Agreement between Global and 4MC."

Please indicate your agreement to the above by signing in the space indicated 
below. In the meantime, please call me if you have any questions.


Sincerely,
