Agreement, and the duties and responsibilities of Escrow Agent under this
Agreement are limited to those expressly and specifically stated in this
Agreement.

            (b)  Escrow Agent will not be personally liable for any act it may
do or omit to do under this Agreement as such escrow agent while acting in good
faith and in the exercise of its own best judgment, and any act done or omitted
by it pursuant to the written advice of its counsel will be conclusive evidence
of such good faith unless, in any event, the same constitutes gross negligence
or willful misconduct.  Escrow Agent will have the right at any time to consult
with its counsel upon any question arising under this Agreement and will incur
no liability for any delay reasonably required to obtain the advise of counsel.

            (c)  Other than those notices or demands expressly provided in this
Agreement, Escrow Agent is expressly authorized to disregard any and all notices
or demands given by Sellers or by any other person, firm or corporation,
excepting only orders or process of court, and Escrow Agent is expressly
authorized to comply with and obey any and all final process, orders, judgment,
or decrees of any court, and to the extent Escrow Agent obeys or complies with
any thereof of any court, it will not be liable to any party to this Agreement
or to any other person, firm or corporation by reason of such compliance.

            (d)  In consideration of the acceptance of this Agreement by Escrow
Agent, Sellers jointly and severally agree, for themselves and their respective
successors and assigns, to promptly pay Escrow Agent its fee and its reasonable
costs and expenses (including court costs and the reasonable fees of its
attorneys, accountants and other consultants and professionals) incurred by it
in connection with its services as escrow agent as contemplated by this
Agreement.  As among themselves, Sellers agree that they will be responsible for
such fee and expenses on a pro rata basis based upon each Seller's portion of
the Sellers' Escrow Shares.  Escrow Agent's fee will be $1,250.  Such sum is
intended as compensation for Escrow Agent's ordinary services as contemplated by
this Agreement.  In the event that Escrow Agent renders services not provided
for in this Agreement, Escrow Agent will be entitled to receive from Sellers
reasonable compensation and reasonable costs for such extraordinary services,
and such compensation and costs will be borne by Sellers on a pro rata basis as
provided above.

            (e)  Escrow Agent will be under no duty or obligation to ascertain
the identity, authority or right of any Sellers (or their agents) to execute or
deliver or purport to execute or deliver this Agreement or any certificates,
documents or papers or payments deposited or called for or given under this
Agreement.

            (f)  Escrow Agent will not be liable for the outlawing of any rights
under any statute of limitations or by reason of laches in respect of this
Agreement or any documents or papers deposited with Escrow Agent.

            (g)  In the event of any dispute among the parties to this Agreement
as to the facts or as to the validity or meaning of any provision of this
Agreement, or any other fact or matter relating to this Agreement or to the
transactions among Sellers, Escrow Agent is instructed that it will be under no
obligation to act, except in accordance with this Agreement or under process or
order of court or, if there be no such process or order, until it has filed or
caused to be filed an appropriate action interpleading Sellers and delivering
the Indemnity Escrow Shares (or the portion thereof in dispute) to such court,
and Escrow Agent will sustain no liability for its failure to act pending such
process of court or order or interpleader of action.

      7.    Modification of Agreement.  The provisions of this Agreement may be
supplemented, altered, amended, modified, or revoked in writing only, signed by
all Sellers and Escrow Agent, and upon payment of all costs and expenses
incident thereto.

      8.    Assignment of Agreement.  No assignment, transfer, conveyance or
hypothecation of any right, title or interest in and to the subject matter of
this Agreement will be binding upon any party, including Escrow Agent, unless
all costs and expenses incident thereto have been paid and then only by the
assent thereto by all parties in writing.

      9.    Miscellaneous.

            (a)  All notices and communications under this Agreement will be in
writing and will be deemed to be duly given if sent by registered mail, return
receipt requested, personal delivery or telecopy (during the recipient's normal
business hours) at the address set forth on Annex 1 attached hereto; or at such
other address or telecopy number as any of the above may have furnished to the
other parties in writing and any such notice or communication given in the
manner specified in this Section 9(a) will be deemed to have been given as of
the date received.  In the event that Escrow Agent, in its sole discretion,
determines that an emergency exists, Escrow Agent may use such other means of
communication as Escrow Agent deems advisable.

            (b)  The undertakings and agreements contained in this Agreement
will bind and inure to the benefit of the parties to this Agreement and their
respective successors and permitted assigns.

            (c)  This Agreement may be executed in one or more counterparts,
each of which will be deemed an original.  Whenever pursuant to this Agreement
Sellers are to deliver a jointly signed writing to Escrow Agent or jointly
advise Escrow Agent in writing, such writing may in each and all cases be signed
jointly or in counterparts and such counterparts will be deemed to be one
instrument.

            (d)  Escrow Agent may resign and be discharged from its duties or
obligations under this Agreement by giving notice in writing of such resignation
to Sellers at least 30 days in advance of such resignation (unless waived in
writing by Sellers).  Such resignation will be effective upon the appointment by
Sellers of a successor escrow agent, which will be a federally chartered bank
having combined capital and surplus of at least $250,000,000.00; provided, that
if any such appointment of any successor agent is not effectuated within 30 days
of such written notice, Escrow Agent may file an action for interpleader and
deposit all funds with a court of competent jurisdiction, all as provided for in
Section 5(g).  Any such successor escrow agent will be appointed by a written
instrument mutually satisfactory to and executed by Sellers, Escrow Agent and
the successor escrow agent.  Any successor escrow agent appointed under the
provisions of this Agreement will have all of the same rights, powers,
privileges, immunities and authority with respect to the matters contemplated
herein as are granted herein to Escrow Agent.

            (e)  Sellers hereby jointly and severally agree to indemnify Escrow
Agent for, and to hold it harmless against, any loss, liability or reasonable
out-of-pocket expense (including court costs and the reasonable fees of its
attorneys, accountants and other consultants and professionals) arising out of
or in connection with this Agreement and carrying out its duties hereunder,
including the reasonable out-of-pocket costs and expenses of defending itself
against any claim of liability, except in those cases where Escrow Agent has
been finally determined by an unappealable order of a court of competent
jurisdiction to have been guilty of gross negligence or willful misconduct. 
Anything in this Agreement to the contrary notwithstanding, in no event will
Escrow Agent be liable for special, indirect or consequential loss or damage of
any kind whatsoever (including, but not limited to, lost profits), even if
Escrow Agent has been advised of the likelihood of such loss or damage and
regardless of the form of action.

            (f)  Sellers are providing Escrow Agent with their Tax
Identification Number (TIN) as assigned by the Internal Revenue Service below
their signatures to this Agreement.  All dividends declared and paid, whether in
cash or in stock, on or with respect to the Deposited Escrow Shares will be
promptly delivered to the Seller who deposited such Deposited Escrow Shares and
reported by the recipient to the Internal Revenue Service as having been
delivered.  Anything to the contrary in this Agreement notwithstanding, the
Seller's Escrow Shares will at all times be owned of record and beneficially by
Sellers, and Sellers will at all times have and be entitled to exercise sole
voting power and, subject to paragraph 5, the power to dispose of or transfer,
the Sellers' Escrow Shares.

            (g)  This Agreement will be governed by and construed in accordance
with the law of the State of Texas without regard to its principles of conflicts
of laws and any action brought under this Agreement will be brought in the
courts of the State of Texas, located in Austin, Travis County, Texas.  Each
party hereto irrevocably waives any objection on the grounds of venue, forum
non-convenience or any similar grounds and irrevocably consents to service of
process by mail or in any other manner permitted by applicable law and consents
to the jurisdiction of such courts.

            (h)  Except as otherwise specified herein, each of the parties will
pay all costs and expenses incurred or to be incurred by it in negotiating and
preparing this Agreement and in closing and carrying out the transactions
contemplated by this Agreement.

            (i)  If any legal action or proceeding is brought for the
enforcement of this Agreement, or because of an alleged dispute, breach, default
or misrepresentation in connection with any of the provisions of this Agreement,
the successful or prevailing party or parties will be entitled to recover
reasonably attorneys' fees and other costs incurred in that action or
proceeding, in addition to any other relief to which it or they may be entitled.

            (j)  The provisions of this Agreement shall apply to any shares or
other securities resulting from any stock split or reverse split,
reclassification, subdivision, consolidation or reorganization of any shares or
other securities of GCI and to any shares or other securities of GCI or any
successor company which may be received by any of the parties hereto by virtue
of their respective ownership of any shares of the Sellers' Escrow Shares.
