                      CDPD VALUE ADDED RESELLER AGREEMENT

     This CDPD Value Added Reseller Agreement (this "Agreement"), dated as of
May 6, 1997 is made between AT&T Wireless Data, Inc., a Delaware corporation
doing business as AT&T Wireless Services, for cellular digital packet data
("CDPD") communications service (defined below) provided by AT&T Wireless Data,
Inc., d/b/a AT&T Wireless Services and its Affiliates, collectively, ("AT&T"),
and GoAmerica, a corporation organized under the laws of the State of Delaware,
for and on behalf of its Affiliates (as defined below) and any permitted
assignee (collectively, "Customer").

                                    RECITALS

     A.  Customer would like to receive Service from AT&T, in connection with
Customer's provision of certain value-added communications services to its End
Users.

     B.  AT&T wishes to provide Service to Customer based upon the value-added
communications services provided by Customer to its End Users, in accordance
with the terms
and conditions of this Agreement.

                                   AGREEMENTS

     In consideration of the mutual promises contained in this Agreement, the
Parties hereby agree as follows:

Section 1.  Definitions

1.1  Affiliate means, with respect to any entity, any other entity that directly
Controls, is Controlled by or is under common Control with the first entity.

1.2  Application means the combination of the Service and Customer's value added
communications services provided to its End Users.  The Application is more
specifically described in Exhibit A hereto.

1.3  Control (and all conjugations thereof) means, with respect to any entity,
the direct or indirect possession of the power to direct the management and
policies of such entity.

1.4  End User means the individuals or entities obtaining access to Service from
Customer.

1.5  Number means, for each End User, the AT&T network and service identifier
numbers and various other network, equipment and service numbers assigned to
Customer for that End User to obtain access to Service.

<PAGE>

1.6  Service means the cellular digital packet data (CDPD) service offered by
AT&T. Cellular digital packet data service generally consists of a wireless data
communications service in which data is sent through a cellular network in a
connectionless packet data format in accordance with the most recent CDPD
specifications, similar to the manner in which data is sent over a TCP/IP Local
Area Network.

1.7  Service Area means those portions of AT&T's CDPD operating areas as
identified by AT&T from time to time (the "Service Area") and as set forth in
Exhibit B hereto, as amended from time to time.

Section 2.  The Service

     2.1  Provision

          2.1.1  Service is available to each of Customer's users or units
within AT&Ts Service Area as long as Customer's CDPD transmitting and receiving
equipment (the "Equipment") is turned on, programmed with AT&T network and
service identifier numbers (collectively, the "Numbers").

          2.1.2  Service provided pursuant to this Agreement will be provided
only upon the request of Customer's authorized representatives, and not by End
Users, and only in connection with the Application.

          2.1.3  Customer is not authorized under this Agreement to use the
Service independent of the Application or in conjunction with any other
Application unless such Application is described and attached in Exhibit A
hereto.

     2.2  Support Services.  AT&T will provide to Customer, and not directly to
End Users, network monitoring, technical assistance and trouble-shooting support
of the Service through AT&T's technical assistance center (the "ATAC").  The
ATAC will be staffed and available to Customer's authorized representatives
twenty-four (24) hours per day, seven (7) days per week to perform these
functions and to address Customer's inquiries.  Customer will provide AT&T with
access to contacts and dispatch information to facilitate appropriate response
to Service interruptions.

     2.3.  Numbers.  Customer shall be issued an initial amount of Numbers as
set forth in the Service Plan attached as Exhibit C hereto. Customer may order
additional Numbers by completing a Service Request Form. Additional Numbers will
be issued to Customer provided Customer is not in default hereof, and subject to
any requirements for a security deposit.  AT&T may change any of Customer's
Numbers from time to time, by giving Customer written notice thereof. AT&T will
use its best efforts to minimize such changes. Customer will inform its End
Users of the provisions of this Section and agrees that neither it nor its End
Users will acquire any proprietary right in any specific Number provided by
AT&T.

     2.4  Use

          2.4.1  Customer will use the Service only for lawful business purposes
and only in connection with the Application, and may resell the Service only in
connection with the Application and as provided by this Agreement.

          2.4.2  AT&T authorizes Customer to provide any or all of the Service
to End Users in connection with End Users' use of the Application.

          2.4.3  AT&T is obligated only to Customer, with which it is in privity
of contract, and not to End Users, with whom AT&T is not in privity.  End Users
are not to be deemed third-party beneficiaries of this Agreement.

          2.4.4  Customer is solely responsible for all risks and expenses
incurred with its actions or omissions in the provision of the Service or the
provision of the Application to End Users, including but not limited to payment
to AT&T for all charges for Service used by Customer or its End Users or third
Parties using a Number assigned to Customer.  In connection with such
activities, Customer will act in all respects for its own account and will be
responsible for such things as credit verification, deposits, billing,
collection, bad debts and any [charges for] unauthorized use of the Service by
End Users or any third Party using a Number assigned to Customer.

          2.4.5  Customer will disclose to End Users the provisions set forth in
Exhibit D.

          2.4.6  Customer is responsible for all End User support regarding all
aspects of End Users' use of the Service (whether arising in connection with
hardware, software or Service), including but not limited to issues relating to
modems, protocol stacks, software configuration and setup, usability issues,
Service activation, Service coverage, billing, and any and all other aspects of
technical services and customer care.  This includes, but is not limited to,
Customer taking the End Users' calls and using reasonable commercial efforts to
remedy any Customer or End User-identified problem without AT&T's participation.
Customer will report a problem to AT&T only upon reasonable verification that
the problem is due to reasons other than misuse, malfunction or the failure of
the Customer Equipment to meet the technical standards for compatibility with
the Service, or failure of the End User to understand how to use the Service.

          2.4.7  The Service will not be used to transmit any communication
where the message, or its transmission or distribution would involve any local
court order or regulation or would likely be offensive to the recipient or
recipients thereof.

     2.5  Continuing Right.  AT&T will have the continuing right to market and
sell the service and any other communications services to any third Parties,
including but not limited to current, future and potential End Users of
Customer.

                                       3
<PAGE>

     2.6  Procedures.  Customer will comply with AT&T's procedures for obtaining
Numbers and for activating Service with respect to any End User. AT&T may from
time to time modify these procedures by giving Customer written notice of such
modification.

     2.7  Service Area.  The Service is available only within the Service Area
and is subject to (a) transmission limitations caused by atmospheric,
topographical or other conditions affecting transmission, (b) equipment
modifications, repairs and other similar activities necessary for the proper or
improved operation of the Service, and (c) equipment failures beyond AT&T`s
reasonable Control.  AT&T will not be responsible for any interruption or
inability to use the Service that results from equipment or systems used in
connection with the Service or the Application.  AT&T may amend Exhibit B to add
or delete any portion of the Service Area from time to time and will use good
faith efforts to provide prior written notice to Customer.

     2.8  Interruptions and Field Trials.  The Service may be temporarily
refused, limited, interrupted or curtailed due to governmental regulations or
orders, system capacity limitations or equipment maintenance, repair,
modifications, upgrades or relocation.  AT&T will make reasonable efforts to
perform scheduled maintenance or repairs on Sundays during the hours of four
(4:00) a.m. to six (6:00) a.m. AT&T will attempt to notify Customer of scheduled
and unscheduled network outages that are expected to last more than two (2)
hours and that may affect the Service.  Customer will cooperate, at AT&T's
expense, in conducting any field tests and trials that AT&T or any Service
provider reasonably determines are necessary or desirable to ensure the
performance and reliability of the Service.

Section 3.  Interconnection

     Customer will be required to obtain and pay for any interconnection
services required to connect Customer to AT&T's CDPD network to be used by End
Users.  In the event that individual connectivity to End Users is required,
Customer will follow AWS policies and procedures for such connections.

Section 4.  Customer Equipment

     Customer will be responsible for the acquisition, programming,
installation, maintenance and repair of all equipment (other than equipment
comprising portions of AT&T's CDPD network) necessary to enable Customer and its
End Users to receive the Service ("Customer Equipment"). Customer will ensure
that all Customer Equipment is technically and operationally compatible with the
Service and meets all applicable federal and state laws, rules and regulations.

Section 5. Rates

5.1  Customer will pay AT&T for Service provided to Customer and its End Users
in accordance with the Service Plan.  Unless the Service Plan provides
otherwise, AT&T shall not increase the rates contained in the Service Plan
within **** from the effective date of this

          and Exchange Commission.

Agreement. Thereafter, however, AT&T may increase the rates contained in the
Service Plan from time to time on thirty days (30) written notice to Customer;
provided, however, if such increase is unacceptable to Customer, Customer may
terminate this Agreement by providing AT&T with written notice at least fifteen
(15) days in advance of such termination. Notwithstanding the foregoing, if AT&T
rescinds its notice of rate increase within such fifteen days, this Agreement
will not terminate, but will remain in full force and effect. AT&T may decrease
the rates contained in the Service Plan from time to time upon written notice to
Customer, effective on the date specified on such notice. To the extent AT&T
arranges for Customer to receive Service from non-AT&T Service providers,
Customer will pay AT&T for Service at Company's regular retail rate for such
Service.

     5.2  *****

Section 6.  Invoices, Payments, Taxes and Security Deposits

     6.1  Invoices.  AT&T will provide Customer written invoices on a monthly
basis.

     6.2  Payment.  Customer will pay each invoice within thirty (30) days
following its receipt thereof.  Any payment not received by the due date will
accrue interest at the rate of one and one-half percent (1.5%) per month or the
maximum lawful rate.  Additional fees will be assessed for any check returned
for insufficient funds.

     6.3.  Disputed Charges.  If the amount of any invoice is disputed, Customer
will pay the entire amount of the invoice by the due date and will include with
such payment a detailed statement sufficient to allow AT&T to ascertain the
disputed amount and the reasons for the dispute.  Any amount not disputed within
ninety (90) days of an invoice due date may not thereafter be disputed.
Customer and AT&T will use good faith efforts to resolve any dispute within
sixty (60) days of receipt of such statement.

     6.4  Taxes.    Customer will pay all applicable federal, state and local
sales, use, public utilities, gross receipts or other taxes or fees imposed on
AT&T as a result of this Agreement (other than taxes imposed on the net income
of AT&T).  Customer will provide certificates of resale required for the states
in which it will resell service, as indicated on Exhibit C.  Customer will
reimburse AT&T for any such taxes or fees paid by AT&T on Customer's behalf.

     6.5.  Security Deposits.  AT&T may from time to time require Customer to
provide it with a cash deposit, irrevocable letter of credit, or other security
acceptable to AT&T based upon AT&T's assessment of Customer's creditworthiness.

Billing Guidelines for Calls.
-----------------------------

          1.  General.  AT&T will bill Customer on a monthly basis for Service
              --------
furnished under this Agreement, including regular monthly Service charges and
usage charges for all data transmissions processed through the Number.  Usage
charges include charges on a per kilobyte basis for transmissions that are sent
or received by Equipment programmed with a Number assigned to Customer.  Usage
charges may also include charges for additional services offered by AT&T which
Customer may subscribe to at rates determined by AT&T from time to time.

          2.  Access Charges.  Access charges are billed monthly in arrears.
              ---------------
Usage charges are billed monthly in arrears.  If AT&T agrees to provide Service
features to Customer, Company reserves the right to charge a reasonable fee for
adding or deleting Service features.

          3.  Measurement.  The measurement of a transmission is in kilobytes.
              ------------

          4.  Loss of Registration.  Registration may be "lost" (i.e.,
              ---------------------
involuntarily disconnected) for a variety of reasons, including atmospheric
conditions, topography, weak batteries, system overcapacity, movement outside a
service area, and gaps in coverage within a service area.  Loss of registration
may result in retransmissions and additional usage charges.

Minimum Number Requirements:
----------------------------

         Customer shall maintain, within ***** of the date of this Agreement, a
minimum of ***** active Numbers.

     Exchange Commission.
                                      16
<PAGE>

Failure to Meet Minimum Number Requirements.  In the event Customer fails to
--------------------------------------------
achieve the minimum Number requirements set forth in this Exhibit C for any
given *****, Customer shall pay to AT&T in addition to all other amounts due the
difference between Customer's actual Numbers and the required minimum Numbers
times the minimum monthly usage set forth in Exhibit C for each ***** in which
Customer fails to achieve such minimum.  Continued failure to meet Minimum
Number Requirements shall give rise to AT&T's right to terminate under section
7.2.4

Promotional Tools: AT&T will provide Customer with up to ***** Numbers, at *****
------------------
*****, with ***** usage in AT&T markets, and up to ***** Numbers at a rate of
*****, with ***** ***** in AT&T markets. Usage outside of AT&T markets and all
taxes on usage relating to such Numbers will remain the responsibility of
Customer.

VAR Rate (SVR) plan to be more competitive with other network providers
offerings as well as to be consistent with our own retail pricing.  We have also
added ***** plans, which hopefully will allow you to be more creative with your
pricing as well as drive higher margins.

To summarize the changes in the ***** plan, we have implemented the following:

The additional rate plans that you can now take advantage of are as follows:
