                               CREDIT AGREEMENT

THIS CREDIT AGREEMENT (as amended, restated and supplemented from time to time,
this "Agreement") by and between UNITED STATES DATA CORPORATION. ("Borrower")
      ---------                                                    --------  
and TEXAS COMMERCE BANK NATIONAL ASSOCIATION ("Bank") is dated as of June 21,
1996 (the "Effective Date").


REVOLVING CREDIT NOTE 1.1  Subject to the terms and conditions hereof, Bank
agrees to make loans ("Loan" or "Loans") to Borrower from time to time before
                       ----      -----                                       
the Termination Date, not to exceed at any one time outstanding $5,000,000.00
(the "Commitment").  Borrower has the right to borrow, repay and reborrow.  The
Loans may only be used to finance ongoing working capital requirements and
general corporate purposes.  . Chapter 15 of the Texas Credit Code will not
apply to this Agreement, the Note or any Loan.  The Loans will be evidenced by,
and will bear interest and be payable as provided in, the promissory note of
Borrower dated the Effective Date (together with any and all renewals,
extensions, modifications and replacements thereof and substitutions therefor,
the "Note").  "Termination Date" means the earlier of: (a) June 20, 1997; or (b)
     ----      ----------------                                                 
the date specified by Bank pursuant to Section 6.1 hereof.

COMMITMENT FEE  1.2  The Commitment is not subject to a commitment fee.

PAST DUE AMOUNTS  1.3  Each amount due to Bank in connection with the Loan
Documents will bear interest from its due date until paid at the Highest Lawful
Rate unless the applicable Loan Document provides otherwise.

CAPITAL ADEQUACY  1.4  If Bank determines after the date of this Agreement that
any change in applicable laws, rules or regulations regarding capital adequacy,
or any change in the interpretation or administration thereof by any appropriate
governmental agency, or compliance with any request or directive to Bank
regarding capital adequacy (whether or not having the force of law) of any such
agency, increases the capital required to be maintained with respect to the Loan
or Note and therefore reduces the rate of return on Bank's capital below the
level Bank could have achieved but for such change or compliance (taking into
consideration Bank's policies with respect to capital adequacy), then Borrower
will pay to Bank from time to time, within 15 days of Bank's request, any
additional amount required to compensate Bank for such reduction.  Bank will
request any additional amount by delivering to Borrower a certificate of Bank
setting forth the amount necessary to compensate Bank.  The certificate will be
conclusive and binding, absent manifest error.  Bank may make any assumptions,
and may use any allocations of costs and expenses and any averaging and
attribution methods, which Bank in good faith finds reasonable.

STATES OF AMERICA.  To the maximum extent permitted by law, any controversy or
claim arising out of or relating to the Loans or any Loan Document, including
but not limited to any claim based on or arising from an alleged tort or an
alleged breach of any agreement contained in any of the Loan Documents, shall,
at the request of any party to the Loan or Loan Documents (either before or
after the commencement of judicial proceedings), be settled by mandatory and
binding arbitration in accordance with the Commercial Arbitration Rules of the
American Arbitration Association (the "AAA Rules") and pursuant to Title 9 of
the United States Code, or if Title 9 does not apply, the Texas General
Arbitration Act.  In any arbitration proceeding: (i) all statutes of limitations
which would otherwise be applicable shall apply; and (ii) the proceeding shall
be conducted in the city in which the office of Bank originating the Loans is
located, by a single arbitrator if the amount in controversy is $1 million or
less, or by a panel of three arbitrators if the amount in controversy (including
but not limited to all charges, principal, interest fees and expenses) is over
$1 million.  Arbitrators are empowered to resolve any controversy by summary
rulings substantially similar to summary judgments and motions to dismiss.
Arbitrators may order discovery conducted in accordance with the Federal Rules

appointment from a panel, pursuant to the AAA Rules.  Any award rendered in the
arbitration proceeding will be final and binding, and judgment upon any such
award may be entered in any court having jurisdiction.
(b) If any party to the Loan or Loan Documents files a proceeding in any court
to resolve any controversy or claim, such action will not constitute a waiver of
the right of such party or a bar to the right of any other party to seek
arbitration under the provisions of this Section or that of any other claim or
controversy, and the court shall, upon motion of any party to the proceeding,
direct that the controversy or claim be arbitrated in accordance with this
(c) No provision of, or the exercise of any rights under, this Section shall
limit or impair the right of any party to the Loan Documents before, during or
after any arbitration proceeding to: (i) exercise self-help remedies including
but not limited to setoff or repossession; (ii) foreclose any Lien on or
security interest in any Collateral; or (iii) obtain relief from a court of
competent jurisdiction to prevent the dissipation, damage, destruction,
transfer, hypothecation, pledging or concealment of assets or Collateral
including, but not limited to attachments, garnishments, sequestrations,
appointments of receivers, injunctions or other relief to preserve the status
(d) To the maximum extent permitted by applicable law and the AAA Rules, neither
Bank nor any Obligor or any Affiliate, officer, director, employee, attorney, or
agent of either shall have any liability with respect to, and Bank and each
Obligor waives, releases, and agrees not to sue any of them upon, any claim for
any special, indirect, incidental and consequential damages suffered or incurred
by such Person in connection with, arising out of, or in any way related to,
this Agreement or any of the other Loan Documents.  Each of Bank and each
Obligor waives, releases, and agrees not to sue each other or any of their
Affiliates, officers, directors, employees, attorneys, or agents for punitive
damages in respect of any claim in connection with, arising out of, or in any
way related to, this Agreement or any of the other Loan Documents, or any of the
transactions contemplated by this Agreement or any of the other Loan Documents.
Nothing contained herein, however, shall be construed as a waiver of any
Obligor's or the Bank's right to compel arbitration of disputes pursuant to
subparagraphs (a) and (b), above.
(e) Nothing herein shall be considered a waiver of the right or protections
afforded Bank by 12 U.S.C. 91, Texas Banking Code Art. 342-609 or any similar
(f) Each party agrees that any other party may proceed against any other liable
Person, jointly or severally, or against one or more of them, less than all,
without impairing rights against any other liable Persons.  A party shall not be
required to join the principal Obligor or any other liable Persons (e.g.,
sureties or guarantors) in any proceeding against any Person.  A party may
release or settle with one or more liable Persons as the party deems fit without
releasing or impairing right to proceed against any Persons not so released.

warranties, covenants and agreements made by or on behalf of Borrower in
connection with the Loan Documents will survive the execution and delivery of
the Loan Documents; will not be affected by any investigation made by any
Person, and will bind Borrower and successors, trustees, receivers and assigns
of Borrower and will benefit the successors and assigns of the Bank; provided
that Bank's agreement to make Loans to Borrower will not inure to the benefit of
any successor or assign of Borrower.  Except as otherwise provided herein, the
term of this Agreement will be until the later of the final maturity of the Note
and the full and final payment of all Obligations and all amounts due under the
Loan Documents.

DOCUMENTARY MATTERS  7.5  This Agreement may be executed in several identical
counterparts, on separate counterparts; each counterpart will constitute an
original instrument, and all separate counterparts will constitute but one and
the same instrument.  The headings and captions in the Loan Documents have been
included solely for convenience and should not be considered in construing the
Loan Documents.  If any provision of any Loan Document is invalid, illegal or
unenforceable in any respect under any applicable law, the remaining provisions
will remain effective.  The Loans and all other obligations and indebtedness of
Borrower to Bank are entitled to the benefit of the Loan Documents.

EXPENSES  7.6  Any provision to the contrary notwithstanding, and whether or not
the transactions contemplated by this Agreement are consummated, Borrower agrees
to pay on demand all out-of-pocket expenses (including, without limitation, the
fees and expenses of counsel for Bank) in connection with the negotiation,
preparation, execution, filing, recording, modification, supplementing and
waiver of the Loan Documents and the making, servicing and collection of the
Loans.  Borrower agrees to pay Bank's standard Documentation Preparation and
Processing Fee for preparation, negotiation and handling of this Agreement.  The
obligations of the Borrower under this and the following section will survive
the termination of this Agreement.


NATURE OF OBLIGATIONS  7.8  If more than one Borrower executes this Agreement,
all of the representations, warranties, covenants and agreements of Borrower
shall be joint and several obligations of all Borrowers.

USURY NOT INTENDED  7.9  Borrower and Bank intend to conform strictly to
applicable usury laws.  Therefore, the total amount of interest (as defined
under applicable law) contracted for, charged or collected under this Agreement
or any other Loan Document will never exceed the Highest Lawful Rate.  If Bank
contracts for, charges or receives any excess interest, it will be deemed a
mistake.  Bank will automatically reform the Loan Document or charge to conform
to applicable law, and if excess interest has been received, Bank will either
refund the excess to Borrower or credit the excess on any unpaid principal
amount of the Note or any other Loan Document.  All amounts constituting
interest will be spread throughout the full term of the Loan Document or
applicable Note in determining whether interest exceeds lawful amounts.


Unless the context otherwise requires, capitalized terms used in Loan Documents
and not defined elsewhere shall have the meanings provided by GAAP, except as

Affiliate means, as to any Person, any other Person (a) that directly or
