Dear Mr. Obray:

      This letter agreement sets forth the terms upon which GoAmerica, Inc., a
Delaware corporation ("GoAmerica"), agrees to enter into discussions regarding a
potential business combination with Hands On Video Relay Services, Inc., a
Delaware corporation, and Hands On Sign Language Services, Inc., a California
corporation (individually and together, the "Companies") (the "Transaction"),
and certain related matters.

      In consideration of the substantial amount of resources GoAmerica will
expend in evaluating and negotiating the terms of the Transaction, for providing
a bridge line of credit to Companies (the "Bridge Line") pursuant to a bridge
line credit agreement (the "Bridge Line Agreement") executed by the parties on
the same date as this letter agreement, and of the mutual covenants set forth
below, GoAmerica and Companies and Ronald and Denise Obray agree as follows:

      1. Other Negotiations. Between the date hereof and 11:59 p.m. (California
time) on June 15, 2005, or such earlier time and date as GoAmerica and Companies
mutually agree to discontinue discussions of the Transaction, or such earlier
date if this letter agreement is terminated because GoAmerica denies a Request
for Loan or fails to make an Advance to Companies under Section 2.1 of the
Bridge Line Agreement or later date as mutually agreed in writing by the parties
(the "Expiration Date"), neither Companies nor its officers, directors or agents
(including, without limitation, Ronald and Denise Obray) will take any action to
solicit, initiate, make, entertain, encourage or seek the submission of, or
facilitate inquiries regarding, or enter into any agreement pursuant to, any
inquiry, proposal or offer from any corporation, partnership, person or other
entity or group (other than discussions with GoAmerica) regarding any
acquisition of Companies, any merger or consolidation with or involving
Companies or any acquisition of any material portion of the stock or assets of
Companies, any other business combination with Companies or any financing of
Companies (any such acquisition, merger, consolidation, business combination or
financing, a "Sale Transaction"). Companies and Ronald and Denise Obray agree
that any such negotiations or activities in progress as of the date hereof will
be terminated or suspended during such period. Companies will promptly, and in
any event within 24 hours, notify GoAmerica regarding any contact by any third
party regarding any offer, proposal or inquiry regarding any. In no event will
Companies or Ronald and Denise Obray accept or enter into an agreement
concerning any such Sale Transaction prior to the Expiration Date.

other under this letter agreement if the parties fail for any reason to execute
such a definitive agreement.

this letter agreement preclude any other or further exercise of such rights or
any other rights under this letter agreement.

      5. Notice. All notices, requests, claims, demands, waivers and other
