ITEM 5.   OTHER EVENTS.

     On July 25, 1996, the Board of Directors of U.S. Long Distance Corp., a
Delaware corporation (the "Company"), declared a pro rata dividend on the
outstanding common stock of the Company, $.01 per share ("Company Common
Stock"), of such number of shares of the common stock, par value $.01 per share
(the "Billing Common Stock"), of Billing Information Concepts Corp. ("Billing"),
as shall be necessary to distribute to stockholders of record of the Company on
the record date for the Distribution one share of Billing Common Stock for each
share of Company Common Stock outstanding on the record date (the
"Distribution").  The dividend is payable to holders of record of Company Common
Stock at the close of business on July 29, 1996.  The Distribution shall be
effective at the commencement of business on August 2, 1996 (the "Distribution
Date").

     Billing is a wholly-owned subsidiary of the Company that will, upon the
effectiveness of the Distribution, own the business and assets of, and will be
responsible for liabilities associated with, the third party billing
clearinghouse and information management services business currently owned by
the Company.  The Distribution will result in 100% of the outstanding shares of
Billing Common Stock being distributed to holders of the Company Common Stock on
a pro rata basis.

     The dividend has been declared pursuant to the terms of a Distribution 
Agreement dated as of July 10, 1996 between the Company and Billing (the 
"Distribution Agreement").The Distribution Agreement provides, among other 
things, for (i) certain preliminary transactions; (ii) the Distribution; 
(iii) the division between Billing and the Company of certain assets and 
liabilities with Billing retaining substantially all of the commercial 
billing clearinghouse and information management services business and the 
Company retaining its direct billing function, pursuant to which the Company 
will continue to directly bill its direct dial long distance charges; (iv) 
the sharing of the obligations under certain warrants previously issued by 
the Company; (v) the issuance by Billing of a stock option to a former 
Company director who has agreed to join the Board of Directors of Billing in 
consideration of his joining the Board of Directors of Billing and to replace 
an expiring, unvested option to acquire shares of Common Stock; and (vi) 
certain other agreements governing the relationship between Billing and the 
Company following the Distribution.  Subject to certain exceptions, the 
Distribution Agreement also provides for assumptions of liabilities and cross 
indemnities designed to allocate, effective as of the Distribution Date, 
financial responsibility for the liabilities arising out of or in connection 
with the third party billing clearinghouse and information management 
services business to Billing and its subsidiaries, and financial 
responsibility for the liabilities arising out of or in connection with the 
direct dial long distance telecommunication services and operator services 
businesses, including the Company's internal billing functions, to the 
Company and its retained subsidiaries.  Under the Distribution Agreement, 
Billing will transfer to the Company on the Distribution Date cash in an 
amount necessary to cause the Company's working capital to be approximately 
$21,500,000 after taking into account payment by the Company of the direct 
costs of the Distribution estimated to be approximately $10,000,000 and the 
receipt by the Company of $8,785,000 in connection with the dissolution of 
its subsidiary MegaPlus Dialing, Inc.  The calculation of this cash amount 
will be based upon current assets and current liabilities as reported on the 
Company's balance sheet at June 30, 1996. 

      To avoid adversely affecting the intended tax consequences of the 
Distribution and related transactions, the Distribution Agreement provides 
that, until the second anniversary of the Distribution Date, the Company must 
obtain an opinion of counsel reasonably satisfactory to Billing or a 
supplemental tax ruling from the Internal Revenue Service before the Company 
may make certain material dispositions of its assets, engage in certain 
repurchases of the Company capital stock or cease the active conduct of its 
business independently, with its own employees and without material changes. 
Because the terms of certain waivers and consents under the Company's and/or 
Billing's, or their respective subsidiaries', debt agreements require that, 
after the Distribution, the Company or Billing, and/or their respective 
subsidiaries, each remain liable as a guarantor and continue to pledge 
security with respect to certain indebtedness that cannot be economically 
separated under existing arrangements and allocated to only the Company or 
only Billing prior to the Distribution Date, each of the Company and Billing 
has agreed in the Distribution Agreement to pay annually to each other a 
credit support fee equal to 1% per annum of the average monthly balance of 
indebtedness guaranteed by one on behalf of the other for as long as such 
guarantees continue after the Distribution Date.

     The Company has also entered into certain other agreements with Billing in
connection with the Distribution Agreement that set forth certain specific
allocations of liabilities between Billing and the Company.  These agreements
include the Benefit Plans and Employment Matters Allocation Agreement, the Tax
Sharing Agreement, the Transitional Services and Sublease Agreement, the Zero
Plus-Zero Minus Billing and Information Management Services Agreement, the One
Plus Billing and Information Management Services Agreement, the
Telecommunications Agreement and the Leasing Agreement, each dated as of July
10, 1996.  The Benefit Plans and Employment Matters Allocation Agreement
provides that, effective as of the Distribution Date, Billing will, or cause one
or more of its subsidiaries to, assume or retain, as the case may be, all
liabilities of the Company, to the extent unpaid as of the Distribution Date,
under employee benefit plans, policies, arrangements, contracts and agreements,
with respect to employees who, on or after the Distribution Date will be
employees of Billing or its subsidiaries, and the Company will, or cause one or
more of its subsidiaries to, assume or retain, as the case may be, all
liabilities of the Company, to the extent unpaid as of the Distribution Date,
under employee benefit plans, policies, arrangements, contracts and agreements
with respect to employees who on or after the Distribution Date 

                                     -2-

will be employees of the Company or its subsidiaries.  The Benefit Plans and 
Employment Matters Allocation Agreement also provides for the adjustment to 
the exercise price of each outstanding option issued under the Company's 1990 
Employee Stock Option Plan and 1993 Non-Employee Director Plan to allocate 
the exercise price of each such option among such option and the option that 
will be issued by Billing immediately prior to the Distribution under similar 
plans adopted by Billing to such option holders for an equal number of shares 
of Billing Common Stock on the basis of the relative fair market values of 
the underlying common stock of each of the Company and Billing after the 
Distribution.  Further, all restrictions on the Company Common Stock awarded 
under the Company's Restricted Stock Plan shall lapse immediately prior to 
the Distribution and all such shares shall vest immediately prior to the 
Distribution.

     The Tax Sharing Agreement provides that with respect to periods ending on
or before September 1996, the fiscal year end for the Company, the Company is
responsible for (i) filing both consolidated federal tax returns for the
Company's affiliated group and combined or consolidated state tax returns for
any group that includes a member of the Company's affiliated group, including in
each case Billing and its subsidiaries for the relevant periods of time such
companies were members of the applicable group, and (ii) paying the taxes
related to such returns (including any subsequent adjustments resulting from the
redetermination of tax liabilities by the applicable taxing authorities).
Billing will reimburse the Company the taxes attributable to Billing or any of
its subsidiaries and the cost of preparation of the associated tax returns
related thereto.

     Under the Transitional Services and Sublease Agreement (i) the Company will
provide to Billing for six months after the Distribution Date certain services
requested by Billing for the conduct of Billing's business; (ii) the Company
will sublease to Billing certain office space on a month to month basis and
certain other office space through March 31, 1997 with Billing to share equally
the Company's out of pocket costs on the space should the Company be unable to
sublease the space for the remainder of the term ending in January 1998; and
(iii) Billing will provide to USLD for six months after the Distribution Date
certain services requested by the Company for the conduct of the Company's
business.  The fee for the Company's and Billing's services will be based on a
cost plus basis or other negotiated arms length basis.  The subleases are on the
same terms and conditions as the terms and conditions of the lease agreements
pursuant to which the Company leases such space from its landlord. Subject to
the termination provisions of the agreement, the Company and Billing will be
free to procure such services from outside vendors or may develop an in-house
capability to provide such services and Billing may lease office space from
outside landlords.

     Under the Zero Plus-Zero Minus Billing and Information Management Services
Agreement and the One Plus Billing and Information Management Services
Agreement, Billing will provide to the Company billing through local telephone
companies for certain qualifying zero plus, zero minus and one plus direct
dialed or operator assisted station to station or person to person calls.  The
Company will be charged for the local telephone company's applicable fees,
charges, chargebacks, credits and adjustments as prescribed in the agreement
between Billing and the local telephone company as well as billing service fees,
charges, chargebacks, credits and assessments of Billing.  Each agreement has an
initial term of three years. The Telecommunications Agreement provides that the
Company will provide to Billing certain direct dial long distance and 800
services for a three year term with additional one year automatic renewal
unless terminated as provided in the agreement.  Finally, under the Leasing
Agreement the Company may elect to lease an airplane owned by Billing on an
hourly or volume usage basis.

     The foregoing summaries of the Distribution Agreement, Benefit Plans and
Employment Matters Allocation Agreement, Tax Sharing Agreement, Transitional
Services and Sublease Agreement, Zero Plus-Zero Minus Billing and Information
Management Services Agreement and Telecommunications Agreement are qualified in
their entirety by reference to the respective agreements that are included as
Exhibits 10.1, 10.2, 10.3, 10.4, 10.5 and 10.6 to this Form 8-K.

     On August 1, 1996, the Board of Directors of the Company received the 
updated opinions, effective as of August 2, 1996, of (i) The Chicago 
Corporation to the effect that, based upon the factors set forth in such 
opinion, the Distribution is in the best interests of the stockholders of the 
Company from a financial point of view after considering other alternatives 
that were available regarding Billing; (ii) Houlihan Lokey Howard & Zukin, 
Inc. to the effect that based upon the conditions set forth therein (a) with 
respect to the Company before the Distribution and with respect to each of 
the Company and Billing, assuming the Distribution is consummated as 
proposed, immediately after and giving effect to the Distribution on a pro 
forma basis (1) the fair value of such company's aggregate assets would 
exceed such company's total liabilities (including contingent liabilities), 
and (2) the present fair salable value for such company's aggregate assets 
would be greater than such company's probable liabilities on its debts as 
such debts become absolute and mature or due; (b) with respect to each of the 
Company and Billing, assuming the Distribution is consummated as proposed, 
immediately after the giving effect to the Distribution (1) such company 
would be able to pay its debts and other liabilities (including contingent 
liabilities) as they become absolute and mature or due, and (2) the capital 
remaining in such company after the Distribution would not be unreasonably 
small for the business in which such company is engaged, as management has 
indicated it is now conducted and is proposed to be conducted following 
consummation of the Distribution; and (c) the excess of the value of 
aggregate assets of the Company, before consummation of the Distribution, 
over the total identified liabilities (including contingent liabilities) of 
the Company would equal or exceed the value of the Distribution to the 
Company stockholders plus the stated capital of the Company; and (iii) Arter 
& Hadden, based upon certain representations made by the Company and Billing,
to the effect, among other things, that receipt of shares of Billing 
Common Stock will be tax free for federal income tax purposes to the 
stockholders of the Company and that the Company will not recognize income, 
gain or loss as a result of the Distribution. The Board of Directors, 
following review and consideration of such opinions, accepted such opinions. 
The Board of Directors determined that all conditions to the Distribution 
have been satisfied. Accordingly, the Board of Directors determined that the 
Distribution shall occur on August 2, 1996.

                           DISTRIBUTION AGREEMENT

      This DISTRIBUTION AGREEMENT (this "Agreement") is made as of this 10th 
day of July, 1996, between U.S. Long Distance Corp., a Delaware corporation 
("USLD"), and Billing Information Concepts Corp., a Delaware corporation and 
wholly-owned subsidiary of USLD ("Billing").

                                  RECITALS

      WHEREAS, USLD, through its subsidiaries, (i) provides direct dial long
distance services, primarily to commercial customers, and operator services for
the hospitality and private pay phone industries (the "Telecommunications
Group") and (ii) provides billing clearinghouse and information management
services for other direct dial long distance and operator services companies and
for information providers, equipment suppliers and other telecommunication
services providers (the "Billing Group").

      WHEREAS, the Board of Directors of USLD has determined that it is in the
best interests of USLD and the stockholders of USLD to separate the 
Telecommunications Group and the Billing Group, and, in order to effect such 
separation, to cause certain USLD subsidiaries conducting the business of the 
Billing Group to merge with and into two wholly owned subsidiaries of Billing 
and for the Telecommunications Group to transfer to Billing certain assets

                             PRELIMINARY TRANSFERS


      Section 2.01.   PRELIMINARY TRANSFERS.  Prior to the Distribution Date,
USLD shall take or cause to be taken all actions necessary (i) to contribute
two of its wholly owned subsidiaries (U.S. Billing Corp. and U.S.
Billing, Inc.) to Billing, (ii) to cause MegaPlus Dialing, Inc., its wholly
owned subsidiary to sell to USLD for $8,785,000 all of the preferred and
common shares of ZeroPlus Dialing, Inc. that it owns and then to dissolve,
(iii) to cause ZeroPlus Dialing, Inc. to redeem all the preferred and
repurchase all of the common shares previously sold by


                                        9 
<PAGE>


MegaPlus Dialing, Inc. to USLD for $8,785,000, (iv) cause its two 
subsidiaries engaged in the Billing Group Business (Zero Plus Dialing, Inc. 
and Enhanced Services Billing, Inc.) to be merged with U.S. Billing Corp. and 
U.S. Billing, Inc., with Zero Plus Dialing, Inc. and Enhanced Services 
Billing, Inc. surviving, and Zero Plus Dialing, Inc. changing its name to 
Billing Information Concepts, Inc., (v) to cause the transfer, assignment, 
delivery and conveyance to Billing or any Billing Group Subsidiary of all of 
USLD's and its Subsidiaries' right, title and interest in the remaining 
Billing Group Assets and (vi) to effect the cash allocation set forth in 
Section 2.07 below.

      Section 2.02.   TRANSFERS OF ASSETS FROM BILLING GROUP SUBSIDIARIES TO
USLD OR TELECOMMUNICATIONS GROUP SUBSIDIARIES.   Prior to the Distribution
Date, Billing shall take or cause to be taken all action necessary to cause the
transfer, assignment, delivery and conveyance to USLD or any Telecommunications
Group Subsidiary of all of Billing's and its Subsidiaries' right, title and
interest in the Telecommunications Group Assets, if any.

      Section 2.03.   TRANSFERS NOT EFFECTED PRIOR TO THE DISTRIBUTION.  To
the extent that any transfers required and legally made by this Article II shall
not have been fully effected on the Distribution Date, the parties shall
cooperate to effect such transfers as promptly as shall be practicable following
the Distribution Date.  Nothing herein shall be deemed to require the transfer
of any assets or the assumption of any Liabilities which by their terms or
operation of law cannot be transferred or assumed; PROVIDED, HOWEVER, that
USLD and Billing and their respective Subsidiaries and Affiliates shall
cooperate in seeking to obtain any necessary consents or approvals for the
transfer of all assets and Liabilities contemplated to be transferred pursuant
to this Article II.  In the event that any such transfer of assets or
Liabilities has not been consummated effective as of the Distribution Date, the
party retaining such asset or Liability shall thereafter hold such asset in
trust for the use and benefit of the party entitled thereto (at the expense of
the party entitled thereto) and retain such Liability for the account of the
party by whom such Liability is to be assumed pursuant hereto, and take such
other actions as may be reasonably required in order to place the parties,
insofar as reasonably possible, in the same position as would have existed had
such asset been transferred or such Liability been assumed as contemplated
hereby.  As and when any such asset or Liability becomes transferable, such
transfer and assumption shall be effected forthwith.  The parties agree that,
except as set forth in this Section 2.03, as of the Distribution Date, each
party hereto shall be deemed to have acquired complete and sole beneficial
ownership over all of the assets, together with all rights, powers and
privileges incidental thereto, and shall be deemed to have assumed in accordance
with the terms of this Agreement all of the Liabilities, and all duties,
obligations and responsibilities incidental thereto, which such party is
entitled to acquire or required to assume pursuant to the terms of this
Agreement.

      Section 2.04.   COOPERATION REGARDING ASSETS.  In the case that at any
time after the Distribution Date, Billing reasonably determines that any of the
Telecommunications Group Assets are essential for the conduct of the Billing
Group Business, or USLD reasonably determines that any of the Billing Group
Assets are essential for the conduct of the Telecommunications Group Business,
and the nature of such assets makes it impracticable for Billing or USLD, as the
case may be, to obtain substitute assets or to make alternative


                                        10 
<PAGE>


arrangements on commercially reasonable terms to conduct their respective 
businesses, and reasonable provisions for the use thereof are not already 
included in the Related Agreements, then Billing (with respect to the Billing 
Group Assets) and USLD (with respect to the Telecommunications Group Assets) 
shall cooperate to make such assets available to the other party on 
commercially reasonable terms, as may be reasonably required for such party 
to maintain normal business operations (provided that such assets shall be 
required to be made available only until such time as the other party may 
reasonably obtain substitute assets or make alternative arrangements on 
commercially reasonable terms to permit it to maintain normal business 
operations.)

      Section 2.05.   NO REPRESENTATIONS OR WARRANTIES; CONSENTS.  Except as 
specifically provided in this Agreement or in any Related Agreement, each of
the parties hereto understands and agrees that no party hereto is, in this
Agreement, in any Related Agreement, or otherwise, representing or warranting in
any way (i) as to the value or freedom from encumbrance of, or any other matter
concerning, any assets of such party, or (ii) as to the legal sufficiency to
convey title to any asset transferred pursuant to this Agreement or any Related
Agreement.  It is also agreed and understood that there are no warranties,
express or implied, as to the merchantability or fitness of any of the assets
either transferred to or retained by the parties, as the case may be, and all
such assets shall be "as is, where is" and "with all faults"; provided, however,
that the absence of warranties shall have no effect upon the allocation of
Liabilities under this Agreement and provided further that Billing represents
and warrants that, prior to the Distribution Date, Billing and the Billing Group
have maintained their cash balances, accounts payable, accounts receivable and
borrowings under their line of credit with FINOVA Capital Corporation in a
manner consistent with the customary practices of the Billing Group Business.
Each party hereto understands and agrees that no party hereto is, in this
Agreement, in any Related Agreement or otherwise, representing or warranting in
any way that the obtaining of any consents or approvals, the execution and
delivery of any amendatory agreements and the making of any filings or
applications contemplated by this Agreement, any Related Agreement or otherwise
will satisfy the provisions of any or all applicable laws or judgments or other
instruments or agreements relating to such assets.  Notwithstanding the
foregoing, the parties shall use their good faith efforts to obtain all consents
and approvals, to enter into all reasonable amendatory agreements and to make
all filings and applications that may be reasonably required for the
consummation of the transactions contemplated by this Agreement and the Related
Agreements, and shall take all such further reasonable actions as shall be
reasonably necessary to preserve for each of the Billing Group and the USLD
Group, to the greatest extent feasible, the economic and operational benefits of
the allocation of assets and Liabilities provided for in this Agreement.  In
case at any time after the Distribution Date any further action is necessary or
desirable to carry out the purposes of this Agreement, proper officers and
directors of each party to this Agreement shall take all such necessary or
desirable action.

      Section 2.06.   PRELIMINARY TRANSFER INSTRUMENTS.  In connection with
the Preliminary Transfers, the merger of USLD's subsidiaries engaged in the
Billing Group Business with wholly owned subsidiaries of Billing, the assignment
of assets and the assumption of Liabilities and other related transactions
contemplated by this Agreement and any Related Agreements, the parties shall
execute, or cause to be executed by the appropriate entities, the Preliminary


                                        11

<PAGE>


Transfer Instruments in such forms as the parties shall reasonably agree.  All
transactions involving capital stock shall be effected by means of delivery of
stock certificates and executed stock powers and notation on the stock record
books of the corporation or other legal entities and, to the extent required by
applicable law, by notation on public registries.

      Section 2.07.   CASH ALLOCATION; CASH MANAGEMENT.

      (a)   CASH ALLOCATION ON THE DISTRIBUTION DATE.  As of the close of 
business on the Distribution Date, Billing shall transfer to USLD out of the 
cash bank balances and short-term investments ("Cash") that it and the 
Billing Group Subsidiaries then hold Cash in an amount necessary for USLD's 
working capital to be approximately $21,500,000 after taking into account the 
payment by USLD of the direct costs of the Distribution and all Preliminary 
Transfers ("USLD Initial Cash Balance"), and Billing shall retain all other 
Cash.  The calculation of the cash amount to be transferred will be based on 
current assets and current liabilities as reported on the USLD balance sheet 
at June 30, 1996.  To the extent practicable, the parties shall use their 
reasonable best efforts to take all necessary action to cause the Cash 
balances of the USLD Group immediately prior to consummation of the 
Distribution to equal the USLD Initial Cash Balance.  In the event the actual 
Cash balances of the USLD Group as of the Distribution are less than the USLD 
Initial Cash Balance, the amount of the deficiency shall be recorded in the 
accounts of USLD and Billing as of the Distribution Date as a payable from 
Billing to USLD (which payable will be paid as promptly as practicable 
following the Distribution); and in the event the actual Cash balances of the 
USLD Group as of the Distribution Date exceeds the USLD Initial Cash Balance, 
the amount of such excess shall be recorded in the accounts of USLD and 
Billing as of the Distribution Date as a payable from USLD to Billing (which 
payable will be paid as promptly as practicable following the Distribution).

      (b)   CASH MANAGEMENT AFTER THE DISTRIBUTION DATE.  Billing shall
establish and maintain a separate cash management system and accounting records
with respect to the Billing Group effective as of 12:01 a.m. on the day
following the Distribution Date.  Thereafter, (i) any payments by USLD or the
Telecommunications Group Subsidiaries on behalf of Billing or the Billing Group
Subsidiaries in connection with the Billing Group (including, without
limitation, any such payments in respect of Liabilities or other obligations of
Billing or the Billing Group Subsidiaries under this Agreement and the Related
Agreements) shall be recorded in the accounts of the Billing Group as a payable
from the Billing Group to the USLD Group; (ii) any payments by Billing or the
Billing Group Subsidiaries on behalf of USLD or the Telecommunications Group
Subsidiaries in connection with the Telecommunications Group Business
(including, without limitation, any such payments in respect of Liabilities or
other obligations of USLD or the Telecommunications Group Subsidiaries under
this Agreement and the Related Agreements) shall be recorded in the accounts of
the USLD Group as a payable from the USLD Group to the Billing Group; (iii) any
cash payments received by USLD and the Telecommunications Subsidiaries relating
to the Billing Group Business shall be recorded in the accounts of the USLD
Group as a payable from the USLD Group to the Billing Group; (iv) any cash
payments received by Billing or the Billing Group Subsidiaries relating to the
Telecommunications Group Business shall be recorded in the accounts of the
Billing Group as a payable from the Billing


                                        12

<PAGE>


Group to the USLD Group; (v) Billing and USLD shall make adjustments for late 
deposits, checks returned for not sufficient funds and other 
post-Distribution Date transactions as shall be reasonable under the 
circumstances consistent with the purpose and intent of this Agreement and 
the Related Agreements; and (vi) the net balance due to the USLD Group or the 
Billing Group, as the case may be, in respect of the aggregate amounts of 
clauses (i), (ii), (iii), (iv) and (v) shall be paid by Billing or USLD, as 
appropriate, as promptly as practicable.  For purposes of this Section 
2.07(b), the parties contemplate that the Telecommunications Group Business 
and the Billing Group Business, including, but not limited to, the respective 
parties' administration of accounts payable and accounts receivable, will be 
conducted in the normal course.


                                 ARTICLE III.

                 ASSUMPTION AND SATISFACTION OF LIABILITIES

      Section 3.01.   ASSUMPTION AND SATISFACTION OF LIABILITIES.   Except as
set forth in the Benefit Plans and Employment Matters Allocation Agreement, the
Tax Sharing Agreement, the Transition Services and Sublease Agreement, the
Leasing Agreement or other Related Agreements, effective as of and after
the Distribution Date, (a) Billing shall, and/or shall cause  the Billing Group
Subsidiaries to, assume, pay, perform and discharge in due course all of the
Billing Group Liabilities, and (b) USLD shall, and/or shall cause the
Telecommunications Group Subsidiaries, to assume, pay, perform and discharge in
due course all of the Telecommunications Group Liabilities.

      Section 3.02.   USLD AND BILLING GUARANTEES.  (a)  Billing shall use its
reasonable best efforts to obtain the release of any USLD Guarantee existing on
and after the Distribution Date.  USLD shall use its best efforts to obtain the
release of any Billing Guarantee existing on and after the Distribution Date.

      (b)   Commencing on the first business day of calendar year 1997 after the
Distribution, and on the first business day of each calendar year thereafter,
Billing shall become obligated to pay to USLD, in cash, a Credit Support Fee in
respect of each USLD Guarantee that was outstanding at any date during the
immediately preceding calendar year and USLD shall become obligated to pay to
Billing, in cash, a Credit Support Fee in respect of each Billing Guarantee that
was outstanding at any date during the immediately preceding calendar year.  The
Credit Support Fee payable with respect to any USLD Guarantee or Billing
Guarantee, as the case may be, shall be an amount equal to the Credit Support
Fee times the average outstanding monthly balance of the principal amount of
indebtedness for the applicable calendar year (and for calendar 1996 from the
Distribution Date through December 31, 1996), the payment of which
is guaranteed pursuant to the applicable USLD Guarantee or Billing Guarantee.
The aggregate amount of any such Credit Support Fee shall be paid by January 31,
of the applicable year.

                                  ARTICLE IV.

                         OBLIGATIONS FOR USLD WARRANTS


      Section 4.01.  SHARING OF WARRANT OBLIGATIONS.  USLD has issued certain 
Warrants, of which approximately 225,000 Warrants were outstanding and 
unexercised as of the date of this Agreement.  USLD and Billing have agreed 
that, in connection with the Distribution, Billing will assume its 
proportionate share of the obligations represented by the Warrants, as set 
forth below in this Article IV.


      Section 4.02.  ISSUANCE OF BILLING COMMON STOCK UPON EXERCISE OF 
WARRANTS.  (a) Following the Distribution Record Date, upon exercise of a 
Warrant to purchase a share of USLD Common Stock and payment of the exercise 
price therefor, at USLD's option, the holder of the Warrant will be entitled 
to receive, in addition to each share of USLD Common Stock issuable upon 
exercise of the Warrant, one share of Billing Common Stock.  Upon receipt of 
a notice of exercise of Warrants, USLD, if it so elects, will 
promptly provide notice thereof to Billing or a transfer agent designated by 
Billing to receive such notice (which notice will contain the number of 
shares of Billing Common Stock issuable by Billing in connection with such 
exercise, the person in whose name such shares are to be issued and the 
address for delivery of the share certificates issuable to such person); and 
in such event Billing shall promptly thereafter (and in any event within five 
Business Days after receipt of such notice) issue the shares of Billing 
Common Stock as set forth in such notice.  Billing and USLD will, and will 
cause their respective transfer agents to, work together in good faith to 
establish procedures to ensure that such notices are received by Billing, and 
such shares are issued by Billing, as promptly as practicable.


      (b)  Notwithstanding the provisions of Section 4.02(a) above, Billing 
shall not be required to issue any frational shares of Billing Common Stock 
upon exercise of any Warrant.  If any fraction of a share of Billing Common 
Stock would, except for the provision of this Section 4.02(b), be issuable on 
the exercise of any Warrants, Billing shall pay to the exercising Warrant 
holder (in lieu of issuance of such fractional share) an amount in cash equal 
to such fraction multiplied by the Billing Warrant Exercise Amount, where the 
"Billing Warrant Exercise Amount" equals the Billing Applicable Percentage 
(as defined below) multiplied by the exercise price paid by the Warrant 
holder upon such exercise.


      Section 4.03.  ALLOCATION OF EXERCISE PRICE.  In the event Billing is 
required to issue shares of Billing Common Stock pursuant to Section 4.02 
above, Billing shall be entitled to receive the Billing Applicable 
Percentage (as defined below) of the exercise price paid upon the exercise of 
any Warrants (which exercise price currently is $12.50 per share for the 
Warrants held by Paytel Northwest, Inc. and $12.50 per share for the Warrants 
held by Communications Central, Inc.).  Such Billing Applicable Percentage 
shall be paid over to Billing by USLD as promptly as practicable following 
USLD's receipt of the exercise price for any Warrants.  The term "Billing 
Applicable Percentage" shall mean the result of the following calculation, 
expressed as a percentage: (i) the Post Distribution Billing Closing Stock 
Price, DIVIDED BY (ii) the sum of (x) the Post Distribution Billing Closing 
Stock Price PLUS (y) the Post Distribution USLD Closing Stock Price.

      Section 4.04.  AMENDMENT TO WARRANTS.  At USLD's option and request, 
Billing agrees to execute prior to the Supplemental Warrant Agreements
reflecting any changes necessary to implement the agreements set forth in this
Article IV.



                                  ARTICLE V.

                      OBLIGATIONS FOR NON-PLAN OPTIONS

      Section 5.01.   GRANT OF NON-PLAN OPTION.  (a) Billing agrees to grant 
to a former USLD Director who has agreed to join the Board of Directors of 
Billing, in consideration of his joining the Billing Board of Directors and 
to replace an unvested option for 5,000 of USLD Common Stock, a non-qualified 
stock option of Billing to purchase 5,000 shares of Billing Common Stock 
("Billing "Non-Plan Option") at an exercise price that preserves the current 
spread between the exercise price of the USLD unvested option and the price of 
the USLD Common Stock as of the Cut Off Date.


      (b) For purposes of determining the exercise price of the Billing 
Non-Plan Option, the following formula shall be used to maintain the holder's 
exercise price spread per share from the unvested USLD option to the Billing 
Non-Plan Option.  The exercise price spread per share shall be maintained by 
setting the exercise price for the Billing Non-Plan Option so that the 
differences between (a) the Post Distribution Billing Closing Stock Price and 
(b) the adjusted price of the Billing Non-Plan Option shall be equal to the 
difference between (y) the USLD Closing Price on the day prior to the Record 
Date and (z) the exercise price of the former Director's USLD unvested option 
on the day prior to the Record Date.


      (c) The obligation of Billing to issue Billing Common Stock upon the 
exercise of the Billing Non-Plan Option shall be adjusted in accordance with 
paragraph 5.01(b).  Except for that adjustment, the terms of the Billing 
Non-Plan Option will be the same as those in effect for the USLD unvested 
option prior to the Distribution.


      (d) Billing agrees to execute and deliver to the Billing Non-Plan 
Option holder following the Distribution the Billing Non-Plan Option 
agreement.



                                  ARTICLE VI.

                               THE DISTRIBUTION

      Section 6.01.   COOPERATION PRIOR TO THE DISTRIBUTION.

      (a)   Billing and USLD shall cooperate in preparing, filing with the
Commission and causing to become effective any registration statements or
amendments thereof that are appropriate to reflect the establishment of, or
amendments to, any employee benefits plans and other plans contemplated by the
Benefit Plans and Employment Matters Allocation Agreement.


                                        15

appropriate under the securities or blue sky laws of states or other political
subdivisions of the United States in connection with the transactions

      (c)   Billing and USLD shall use all reasonable efforts to obtain any
third-party consents or approvals necessary or desirable in connection with the
transactions contemplated hereby ("Consents").

      (d)   Billing and USLD will use all reasonable efforts to take, or cause
to be taken, all actions, and to do, or cause to be done, all things necessary
or desirable under applicable law, to consummate the transactions contemplated
under this Agreement and the Related Agreements.

      Section 6.02.   USLD BOARD ACTION; CONDITIONS PRECEDENT TO THE

            (viii) Billing's application to effect the listing of the Billing

            (ix)   the transactions contemplated hereby shall be in compliance

            (xii)  no material adverse change shall have occurred with 
respect to USLD or Billing, the securities markets or general economic or

Billing, make the transactions contemplated by this Agreement inadvisable.

PROVIDED, HOWEVER, that (x) any such condition may be waived by the USLD
Board in its sole discretion, and (y) the satisfaction of such conditions shall
not create any obligation on the part of USLD or any other party hereto to

forth in Section 11.07 or alter the consequences of any such termination from
those specified in such Section.

      Section 6.03.   THE DISTRIBUTION.  On the Distribution Date, subject to

                                 ARTICLE VII.

                               INDEMNIFICATION

      Section 7.01.   INDEMNIFICATION BY USLD.  Except as otherwise expressly
set forth in a Related Agreement, USLD shall indemnify, defend and hold harmless
Billing and each of the Billing Group Subsidiaries, and each of their respective
directors, officers, employees, agents and Affiliates and each of the heirs,
executors, successors and assigns of any of the foregoing


                                        17 
<PAGE>


(the "Billing Indemnitees") from and against the Telecommunications Group 
Liabilities and any and all losses, Liabilities, damages including without 
limitation, the costs and expenses of any and all Actions, threatened 
Actions, demands, assessments, judgments, settlements and compromises 
relating thereto and attorneys' fees and any and all expenses whatsoever 
reasonably incurred in investigating, preparing or defending against any such 
Actions or threatened Actions (collectively, "Billing Indemnifiable Losses" 
and, individually, a "Billing Indemnifiable Loss") of the Billing Indemnitees 
arising out of or due to the failure or alleged failure of USLD, any 
Telecommunications Group Subsidiary, or any of their respective Affiliates to 
(i) pay, perform or otherwise discharge in due course any of the 
Telecommunications Group Liabilities, or (ii) comply with the provisions of 
Section 7.04.  To the extent that counsel is provided to Billing under this 
indemnification, such counsel shall be selected by USLD and such counsel may 
include its in-house corporate counsel.

      Section 7.02.   INDEMNIFICATION BY BILLING.  Except as otherwise
expressly set forth in a Related Agreement, Billing shall indemnify, defend and
hold harmless USLD and each of the Telecommunications Group Subsidiaries, and
each of their respective directors, officers, employees, agents and Affiliates
and each of the heirs, executors, successors and assigns of any of the foregoing
(the "USLD Indemnitees") from and against the Billing Group Liabilities and any
and all losses, Liabilities, damages, including, without limitation, the costs
and expenses of any and all Actions, threatened Actions, demands, assessments,
judgments, settlements and compromises relating thereto and attorneys' fees and
any and all expenses whatsoever reasonably incurred in investigating, preparing
or defending against any such Actions or threatened Actions (collectively, "USLD
Indemnifiable Losses" and, individually, a "USLD Indemnifiable Loss") of the
USLD Indemnitees arising out of or due to the failure or alleged failure of
Billing, any Billing Group Subsidiaries, or any of their respective Affiliates
to (i) pay, perform or otherwise discharge in due course any of the Billing
Group Liabilities or (ii) comply with the provisions of Section 7.04.  The
"Billing Indemnifiable Losses" and the "USLD Indemnifiable Losses" are
collectively referred to as the "Indemnifiable Losses."  To the extent that
counsel is provided to USLD under this Indemnification, such counsel shall be
selected by Billing and such counsel may include its in-house corporate counsel.

      Section 7.03.   INSURANCE PROCEEDS.  The amount that any party (an
"Indemnifying Party") is or may be required to pay to any other Person (an
"Indemnitee") pursuant to Section 7.01 or Section 7.02 shall be reduced
(including, without limitation, retroactively) by any Insurance Proceeds or
other amounts actually recovered by or on behalf of such Indemnitee in reduction
of the related Indemnifiable Loss.  If an Indemnitee shall have received the
payment required by this Agreement from an Indemnifying Party in respect of an
Indemnifiable Loss and shall subsequently actually receive Insurance Proceeds,
or other amounts in respect of such Indemnifiable Loss as specified above, then
such Indemnitee shall pay to such Indemnifying Party a sum equal to the amount
of such Insurance Proceeds or other amounts actually received.

      Section 7.04.   PROCEDURE FOR INDEMNIFICATION.  (a)  Except as may be
set forth in a Related Agreement, if an Indemnitee shall receive notice or
otherwise learn of the assertion by a Person (including, without limitation, any
governmental entity) who is not a party to this Agreement or to any of the
Related Agreements of any claim or of the commencement by any


                                        18

<PAGE>


such Person of any Action with respect to which an Indemnifying Party may be 
obligated to provide indemnification pursuant to this Agreement (a 
"Third-Party Claim"), such Indemnitee shall give such Indemnifying Party 
written notice thereof promptly after becoming aware of such Third-Party 
Claim; PROVIDED, that the failure of any Indemnitee to give notice as 
required by this Section 7.04 shall not relieve the Indemnifying Party of its 
obligations under this Article VII, except to the extent that such 
Indemnifying Party is prejudiced by such failure to give notice.  Such notice 
shall describe the Third-Party Claim in reasonable detail, and shall indicate 
the amount (estimated if necessary) of the Indemnifiable Loss that has been 
or may be sustained by such Indemnitee.

      (b)   An Indemnifying Party may elect to defend or to seek to settle or
compromise, at such Indemnifying Party's own expense and by such Indemnifying
Party's own counsel, any Third-Party Claim, provided that the Indemnifying Party
must confirm in writing that it agrees that the Indemnitee is entitled to
indemnification hereunder in respect of such Third-Party Claim.  Within 20 days
of the receipt of notice from an Indemnitee in accordance with Section 7.04(a)
(or sooner, if the nature of such Third-Party Claim so requires), the
Indemnifying Party shall notify the Indemnitee of its election whether to assume
responsibility for such Third-Party Claim (provided that if the Indemnifying
Party does not so notify the Indemnitee of its election within 20 days after
receipt of such notice from the Indemnitee, the Indemnifying Party shall be
deemed to have elected not to assume responsibility for such Third-Party Claim),
and such Indemnitee shall cooperate in the defense or settlement or compromise
of such Third-Party Claim.  After notice from an Indemnifying Party to an
Indemnitee of its election to assume responsibility for a Third-Party Claim,
such Indemnifying Party shall not be liable to such Indemnitee under this
Article VII for any legal or other expenses (except expenses approved in advance
by the Indemnifying Party) subsequently incurred by such Indemnitee in
connection with the defense thereof; PROVIDED, that if the defendants in any
such claim include both the Indemnifying Party and one or more Indemnitees and
in such Indemnitees' reasonable judgment a conflict of interest between such
Indemnitees and such Indemnifying Party exists in respect of such claim, such
Indemnitees shall have the right to employ separate counsel and in that event
the reasonable fees and expenses of such separate counsel (but not more than one
separate counsel reasonably satisfactory to the Indemnifying Party) shall be
paid by such Indemnifying Party.  If an Indemnifying Party elects not to assume
responsibility for a Third-Party Claim (which election may be made only in the
event of a good faith dispute that a claim was inappropriately tendered under
Section 7.01 or 7.02, as the case may be) such Indemnitee may defend or (subject
to the following sentence) seek to compromise or settle such Third-Party Claim.
Notwithstanding the foregoing, an Indemnitee may not settle or compromise any
claim without prior written notice to the Indemnifying Party, which shall have
the option within 10 days following the receipt of such notice (i) to disapprove
the settlement and assume all past and future responsibility for the claim,
including reimbursing the Indemnitee for prior expenditures in connection with
the claim, or (ii) to disapprove the settlement and continue to refrain from
participation in the defense of the claim, in which event the Indemnifying Party
shall have no further right to contest the amount or reasonableness of the
settlement if the Indemnitee elects to proceeds therewith, or (iii) to approve
the amount of the settlement, reserving the Indemnifying Party's right to
contest the Indemnitee's right to indemnity, or (iv) to approve and agree to pay
the settlement.  In the event


                                        19

<PAGE>


the Indemnifying Party makes no response to such written notice from the 
Indemnitee, the Indemnifying Party shall be deemed to have elected option 
(ii).

      (c)   If an Indemnifying Party chooses to defend or to seek to compromise
any Third-Party Claim, the Indemnitee shall make available to such Indemnifying
Party any personnel and any books, records or other documents within its control
or which it otherwise has the ability to make available that are necessary or
appropriate for such defense.

      (d)   Any claim on account of an Indemnifiable Loss that does not result
from a Third-Party Claim shall be asserted by written notice given by the
Indemnitee to the applicable Indemnifying Party.  Such Indemnifying Party shall
have a period of 15 days after the receipt of such notice within which to
respond thereto.  If such Indemnifying Party does not respond within such 15-day
period, such Indemnifying Party shall be deemed to have refused to accept
responsibility to make payment.  If such Indemnifying Party does not respond
within such 15-day period or rejects such claim in whole or in part, such
Indemnitee shall be free to pursue such remedies as may be available to such
party under applicable law or under this Agreement.

      (e)   In addition to any adjustments required pursuant to Section 7.03, if
the amount of any Indemnifiable Loss shall, at any time subsequent to the
payment required by this Agreement, be reduced by recovery, settlement or
otherwise, the amount of such reduction, less any expenses incurred in
connection therewith, shall promptly be repaid by the Indemnitee to the
Indemnifying Party.

      (f)   In the event of payment by an Indemnifying Party to any Indemnitee
in connection with any Third-Party Claim, such Indemnifying Party shall be
subrogated to and shall stand in the place of such Indemnitee as to any events
or circumstances in respect of which such Indemnitee may have any right or claim
relating to such Third-Party Claim against any claimant or plaintiff asserting
such Third-Party Claim.  Such Indemnitee shall cooperate with such Indemnifying
Party in a reasonable manner, and at the cost and expense of such Indemnifying
Party, in prosecuting any subrogated right or claim.

      Section 7.05.   REMEDIES CUMULATIVE.  The remedies provided in this
Article VII shall be cumulative and shall not preclude assertion by any
Indemnitee of any other rights or the seeking of any and all other remedies
against any Indemnifying Party.

      Section 7.06.   SURVIVAL OF INDEMNITIES.  The obligations of each of
Billing and USLD under this Article VII shall survive the sale or other transfer
by it of any assets or businesses or the assignment by it of any Liabilities,
with respect to any Indemnifiable Loss of the other related to such assets,
businesses or Liabilities.


                                 ARTICLE VIII.

Saltzman, Lee Cooke and James E. Sowell.


      Section 8.02.   RESIGNATIONS; USLD BOARD.  Billing shall cause all of
its directors and Billing Group Employees to resign, effective as of the
Distribution Date, from all boards of directors or similar governing bodies of
USLD or any of its Subsidiaries on which they serve, and from all positions as

except that Parris H. Holmes, Jr. shall serve as a director of both Billing and
USLD and as Chairman of both the USLD Board and the Billing Board.  USLD shall
cause all of its directors and the Telecommunications Group Employees to resign
from all boards of directors or similar governing bodies of Billing or any of
its Subsidiaries on which they serve, and from all positions as officers or
employees of Billing or any of its Subsidiaries in which they serve, except that
Parris H. Holmes, Jr. shall serve as a director of both Billing and USLD and as
Chairman of both the USLD Board and the Billing Board and as Chief Executive
Officer of Billing.

      Section 8.03.   CERTIFICATE AND BYLAWS.  On or prior to the Distribution
Date, Billing shall adopt the Billing Certificate and the Billing Bylaws, and
shall file the Billing Certificate with the Secretary of State of the State of
Delaware.  USLD shall provide all necessary stockholder approvals for the
Billing Certificate prior to the filing of the Billing Certificate with the
Secretary of State of the State of Delaware.

      Section 8.04.   CERTAIN POST-DISTRIBUTION TRANSACTIONS.


      (a)   BILLING.  (i) Billing shall, and shall cause each of the Billing
Group Subsidiaries to, comply with each representation and statement made, or to
be made, to any Person in connection with the Tax Opinion with respect to any
transaction contemplated by this Agreement, and (ii) until the second
anniversary of the Distribution Date, neither Billing nor any of its
Subsidiaries shall (a) make a material disposition, by means of a sale or
exchange of assets or capital stock, a distribution to stockholders or
otherwise, of any substantial portion of its assets, (b) repurchase or issue any
Billing capital stock (other than stock issued pursuant to employee plans or
outstanding options or Warrants), or (c) in the case of Billing, cease the
active conduct of a material portion of its business independently, with its own
employees and without material change, unless, in each of cases (a), (b) and
(c), in the opinion of counsel to Billing, which opinion shall be reasonably
satisfactory to USLD, or pursuant to a favorable IRS letter ruling or tax
opinion reasonably satisfactory to USLD, such act or omission would not
adversely affect the tax consequences of the Distribution to USLD or the
stockholders of USLD, as set forth in any ruling issued by any taxing authority
or tax opinion; and Billing has no present intention to take any such actions.


      (b)   USLD.  (i) USLD shall, and shall cause each of the
Telecommunications Group Subsidiaries to comply with each representation and
statement made, or to be made, to any Person in connection with the Tax Opinion
with respect to any transaction contemplated by this Agreement; and (ii) until

                                        21

<PAGE>


of its Subsidiaries shall (a) make a material disposition, by means of a sale 
or exchange of assets or capital stock, a distribution to stockholders or 
otherwise, of any substantial portion of its assets (other than Billing Group 
Assets in connection with the Distribution or transactions effected in 
contemplation thereof), (b) repurchase or issue any capital stock of USLD 
(other than stock issued pursuant to employee plans or outstanding options or 
Warrants), or (c) in the case of USLD, cease the active conduct of a material 
portion of its business independently, with its own employees and without 
material change, unless, in each of cases (a), (b) and (c), in the opinion of 
counsel to USLD, which opinion shall be reasonably satisfactory to Billing, 
or pursuant to a favorable IRS letter ruling or tax opinion reasonably 
satisfactory to Billing, such act or omission would not adversely affect the 
tax consequences of the Distribution to Billing or the stockholders of 
Billing, as set forth in any ruling issued by any taxing authority or tax 
opinion; and USLD has no present intention to take any such actions.

      Section 8.05.   BILLING RIGHTS PLAN.  Prior to the Distribution Date,
the Billing Board may elect, in its sole discretion, to recommend that Billing
adopt a stockholder rights plan (the "Billing Rights Plan").  The Billing Rights
Plan will be substantially similar to the USLD Rights Plan and will provide for
the distribution of preferred share purchase rights ("Billing Rights") with
respect to each share of Billing Common Stock.  The Billing Rights will be
attached to the Billing Common Stock and will not be exercisable, or
transferrable apart from the Billing Common Stock, unless and until certain
events occur.  If certain events occur relating to the acquisition by an
acquiring person of Billing Common Stock, or a merger or other combination of
Billing with an acquiring person, the Billing Rights will entitle holders (other
than the acquiring person) to purchase either Billing Common Stock or common
stock of the acquiring person at a discount.  The specific terms of the Billing
Rights will be determined by the Board of Directors of Billing consistent with
the description thereof in the Information Statement.

      Section 8.06.   USE OF THE "USLD" NAME AND THE USLD LOGO.
Notwithstanding anything to the contrary in this Agreement (including the
conveyance to Billing of the Transferred Intellectual Property) or in any
Related Agreement, the parties hereto agree that USLD shall retain the exclusive
right to use the mark "USLD" without limitation or expiration and the right to
use the USLD Logo following the Distribution.

      Section 8.07.   NONCOMPETITION AGREEMENT; RESTRICTED TRANSACTIONS.  (a)
Each USLD and Billing agrees that for a period of one (1) year after the
Distribution Date, whether a breach of this Agreement or any Related Agreement
is alleged or not, neither USLD nor Billing will, without the prior written
consent of the other, which consent may be withheld in the sole discretion of
each, engage, whether for compensation or not, as an owner, partner,
stockholder, investor or in any other capacity whatsoever in any activity or
endeavor that competes directly or indirectly with the business of the other as
engaged in, or proposed to be engaged in, as of the Distribution Date; provided,
however, that nothing contained herein shall prohibit either USLD or Billing
from engaging in a merger, consolidation or other business combination with
another person or entity with departments or divisions that competes with either
USLD or Billing, as the case may be.  Such restriction applies worldwide.



                                        22

<PAGE>


      (b)   Each USLD and Billing further agrees for a period of six (6) 
months after the Distribution Date, notwithstanding any allegation of breach 
of this Agreement or any Related Agreement, not, without the prior written 
consent of the other, to solicit, influence or attempt to influence any 
employee of the other to terminate his or her employment or other contractual 
relationship with his or her respective employer for any reason including, 
without limitation, working for such soliciting party.  Either Billing or 
USLD may elect to pay to the other fifty percent (50%) of the total previous 
12 months salary and bonus of any employee of the other for the privilege of 
soliciting the employment of such employee without the necessity of obtaining 
the consent of the employing party.

      (c)   The covenants of USLD and Billing contained in Section 8.07 will be
construed as independent of any other provision in this Agreement; and the
existence of any claim or cause of action by USLD or Billing against the other
will not constitute a defense to the enforcement of said covenants.  Each USLD
and Billing further agrees and acknowledges that this Section 8.07 (1) is
reasonable as to length of time, scope and geographic area for purposes of
protecting the commercial advantages enjoyed by each USLD and Billing, (2) does
not impose a greater restraint than is necessary to protect the goodwill or
business interests of each USLD and Billing and (3) is more than adequately paid
for in the consideration derived by each USLD and Billing under this Agreement.
Each of USLD and Billing also agree that the arbitrators (under Section 11.13)
have jurisdiction to modify any provisions of this Section 8.07 in accordance
with the court's or arbitrators' respective ruling as to reasonableness or scope
of application and that this Agreement shall remain enforceable as modified or
amended in the jurisdiction where this Agreement is so modified or amended.

                                  ARTICLE IX.

      Section 9.01.   PROVISION OF CORPORATE RECORDS.

      (a)   Except as may otherwise be provided in a Related Agreement, USLD
shall arrange as soon as practicable following the Distribution Date, to the
extent not previously delivered in connection with the transactions contemplated
in Article II, for the transportation (at Billing's cost) to Billing of the
Billing Books and Records in USLD's possession, except to the extent such items
are already in the possession of Billing or a Billing Subsidiary.  The Billing
Books and Records shall be the property of Billing, but shall be available to
USLD for review and duplication until USLD shall notify Billing in writing that
such records are no longer of use to USLD.

      (b)   Except as otherwise provided in a Related Agreement, Billing shall
arrange as soon as practicable following the Distribution Date, to the extent
not previously delivered in connection with the transactions contemplated in
Article II, for the transportation (at USLD's cost) to USLD of the USLD Books
and Records in Billing's possession, except to the extent such items are already
in the possession of USLD.  The USLD Books and Records shall be the property of
USLD, but the USLD Books and Records that reasonably relate to the Billing Group


                                        23 
<PAGE>

Business shall be available to Billing for review and duplication until Billing
shall notify USLD in writing that such records are no longer of use to Billing.

      Section 9.02.   ACCESS TO INFORMATION.

      Except as otherwise provided in a Related Agreement, from and after the
Distribution Date, USLD shall afford to Billing and its authorized accountants,
counsel and other designated representatives reasonable access (including using
reasonable efforts to give access to persons or firms possessing information)
and duplicating rights during normal business hours to all records, books,
contracts, instruments, computer data and other data and information relating to
pre-Distribution operations (collectively, "INFORMATION") within USLD's
possession insofar as such access is reasonably required by Billing for the
conduct of its business, subject to appropriate restrictions for classified or
Privileged Information.  Similarly, except as otherwise provided in a Related
Agreement, Billing shall afford to USLD and its authorized accountants, counsel
and other designated representatives reasonable access (including using
reasonable efforts to give access to persons or firms possessing information)
and duplicating rights during normal business hours to Information within
Billing's possession, insofar as such access is reasonably required by USLD for
the conduct of its business, subject to appropriate restrictions for classified
or Privileged Information.  Information may be requested under this Article IX
for the legitimate business purposes of either party, including without
limitation, audit, accounting, claims (including claims for indemnification
hereunder), litigation and tax purposes, as well as for purposes for fulfilling
disclosure and reporting obligations and for performing this Agreement and the
transactions contemplated hereby.  The parties hereby agree that Billing shall
also grant to USLD reasonable access to data maintained by Billing after the
Distribution that contain data and other information reasonably related to the
Telecommunications Group Assets or the Telecommunications Group Business, for
purposes of review and retrieval of such data (including the generation of
reports containing such data).  USLD agrees to reimburse Billing for the
reasonable costs of the use of such computer systems.  The parties also agree
that USLD shall grant to Billing reasonable access to data maintained by USLD
after the Distribution that certain data and other information reasonably
related to the Billing Group Assets or the Billing Group Business, for purposes
of review and retrieval of such data (including the generation of reports
containing such data).  Billing agrees to reimburse USLD for the reasonable
costs of the use of such computer systems.

      Section 9.03.   PRODUCTION OF WITNESSES.  At all times from and after
the Distribution Date, each of Billing and USLD shall use reasonable efforts to
make available to the other, upon written request, its and its Subsidiaries'
officers, directors, employees and agents as witnesses to the extent that such
persons may reasonably be required in connection with any Action.

      Section 9.04.   REIMBURSEMENT.  Except to the extent otherwise
contemplated in any Related Agreement, a party providing Information or witness
services to the other party under this Article IX shall be entitled to receive
from the recipient, upon the presentation of invoices therefor, payments of such
amounts, relating to supplies, disbursements and other out-of-pocket expenses
(at cost) and direct and indirect expenses of employees who are witnesses or
otherwise 


                                        24 
<PAGE>

furnish assistance (at cost), as may be reasonably incurred in
providing such Information or witness services.

      Section 9.05.   RETENTION OF RECORDS.  Except as otherwise required by
law or agreed to in a Related Agreement or otherwise in writing, each of Billing
and USLD may destroy or otherwise dispose of any of the Information, which is
material Information and is not contained in other Information retained by USLD
or Billing, as the case may be, at any time after the tenth anniversary of this
Agreement, provided that, prior to such destruction or disposal, (a) it shall
provide no less than 90 or more than 120 days prior written notice to the other,
specifying in reasonable detail the Information proposed to be destroyed or
disposed of and (b) if a recipient of such notice shall request in writing prior
to the scheduled date for such destruction or disposal that any of the
Information proposed to be destroyed or disposed of be delivered to such
requesting party, the party proposing the destruction or disposal shall promptly
arrange for the delivery of such of the Information as was requested at the
expense of the party requesting such Information.

      Section 9.06.   CONFIDENTIALITY.  Each of USLD and its Subsidiaries on
the one hand, and Billing and its Subsidiaries on the other hand, shall hold,
and shall cause its consultants and advisors to hold, in strict confidence, all
Information concerning the other in its possession or furnished by the other or
the other's representatives pursuant to this Agreement or the Related Agreements
(except to the extent that such Information has been (i) in the public domain
through no fault of such party or (ii) later lawfully acquired from other
sources by such party), and each party shall not release or disclose such
Information to any other person, except its auditors, attorneys, financial
advisors, rating agencies, bankers or other consultants and advisors, unless
compelled to disclose by judicial or administrative process, or as reasonably
advised by its counsel or by other requirements of law, or unless such
Information is reasonably required to be disclosed in connection with (x) any
litigation with any third-parties or litigation between the USLD Group and the
Billing Group, (y) any contractual agreement to which the USLD Group or the
Billing Group are currently parties, or (z) in exercise of either party's rights
hereunder or under any Related Agreement.

      Section 9.07.   PRIVILEGED MATTERS.  Billing and USLD recognize that
legal and other professional services that have been and will be provided prior
to the Distribution Date have been and will be rendered for the benefit of both
the USLD Group and the Billing Group and that both the USLD Group and the
Billing Group should be deemed to be the client for the purposes of asserting
all Privileges.  To allocate the interests of each party in the Privileged
Information, the parties agree as follows:

      (a)   USLD shall be entitled, in perpetuity, to control the assertion or
waiver of all Privileges in connection with Privileged Information that relates
solely to the Telecommunications Group, whether or not Privileged Information is
in the possession of or under the control of USLD or Billing.  USLD shall also
be entitled, in perpetuity, to control the assertion or waiver of all Privileges
in connection with Privileged Information that relates solely to the subject
matter of any claims constituting Telecommunications Group Liabilities, now
pending or which may be asserted in the future, in any lawsuits or other
proceedings initiated


                                        25

<PAGE>


against or by USLD, whether or not the Privileged Information is in the 
possession of or under the control of USLD or Billing.

      (b)   Billing shall be entitled, in perpetuity, to control the assertion
or waiver of all Privileges in connection with Privileged Information that
relates solely to the Billing Group, whether or not the Privileged Information
is in the possession of or under the control of USLD or Billing.  Billing shall
also be entitled, in perpetuity, to control the assertion or waiver of all
Privileges in connection with Privileged Information that relates solely to the
subject matter of any claims constituting Billing Group Liabilities, now pending
or which may be asserted in the future, in any lawsuits or other proceedings
initiated against or by Billing, whether or not the Privileged Information is in
the possession of Billing or under the control of USLD or Billing.

      (c)   Billing and USLD agree that they shall have a shared Privilege, with
equal right to assert or waive, subject to the restrictions in this Section
9.07, with respect to all Privileges not allocated pursuant to the terms of
Sections 9.07(a) and (b).  All Privileges relating to any claims, proceedings,
litigation, disputes, or other matters that involve both Billing and USLD in
respect of which Billing and USLD retain any responsibility or liability under
this Agreement or any Related Agreement, shall be subject to a shared Privilege.

      (d)   No party may waive any Privilege that could be asserted under any
applicable law, and in which the other party has a shared Privilege, without the
consent of the other party, except to the extent reasonably required in
connection with any litigation with third-parties or as provided in subsection
(e) below.  Consent shall be in writing, or shall be deemed to be granted unless
written objection is made within 20 days after notice upon the other party
requesting such consent.

      (e)   In the event of any litigation or dispute between a member of the
USLD Group and a member of the Billing Group, either party may waive a Privilege
in which the other party has a shared Privilege, without obtaining the consent
of the other party, provided that such waiver of a shared Privilege shall be
effective only as to the use of Information with respect to the litigation or
dispute between the USLD Group and the Billing Group, and shall not operate as a
waiver of the shared Privilege with respect to third-parties.

      (f)   If a dispute arises between the parties regarding whether a
Privilege should be waived to protect or advance the interest of either party,
each party agrees that it shall negotiate in good faith, shall endeavor to
minimize any prejudice to the rights of the other party, and shall not
unreasonably withhold consent to any request for waiver by the other party.
Each party specifically agrees that it will not withhold consent to waiver for
any purpose except to protect its own legitimate interests.

      (g)   Upon receipt by any party of any subpoena, discovery or other
request that arguably calls for the production or disclosure of Information
subject to a shared Privilege or as to which the other party has the sole right
hereunder to assert a Privilege, or if any party obtains knowledge that any of
its current or former directors, officers, agents or employees have received any
subpoena, discovery or other requests that arguably calls for the production or


                                        26

<PAGE>


disclosure of such Privileged Information, such party shall promptly notify 
the other party of the existence of the request and shall provide the other 
party a reasonable opportunity to review the Information and to assert any 
rights it may have under this Section 9.07 or otherwise to prevent the 
production or disclosure of such Privileged Information.

      (h)   The transfer of the Billing Books and Records and the USLD Books and
Records and other Information between USLD and its Subsidiaries and Billing and
its Subsidiaries, is made in reliance on the agreement of Billing and USLD, as
set forth in Sections 9.06 and 9.07, to maintain the confidentiality of
Privileged Information and to assert and maintain all applicable Privileges.
The access to information being granted pursuant to Sections 9.01 and 9.02
hereof, the agreement to provide witnesses and individuals pursuant to Section
9.03 hereof and the transfer of Privileged Information between USLD and its
Subsidiaries and Billing and its Subsidiaries pursuant to this Agreement shall
not be deemed a waiver of any Privilege that has been or may be asserted under
this Agreement or otherwise.


                                  ARTICLE X.

                                  INSURANCE

      Section 10.01.  POLICIES AND RIGHTS INCLUDED WITHIN THE BILLING GROUP
ASSETS.  Without limiting the generality of the definition of the Billing Group
Assets set forth in Section 2.01 or the effect of Section 2.01, the Billing
Group Assets shall include (a) any and all rights of an insured party under each
of the Shared Policies, specifically including rights of indemnity and the right
to be defended by or at the expense of the insurer, with respect to all
injuries, losses, liabilities, damages and expenses incurred or claimed to have
been incurred on or prior to the Distribution Date by any party in or in
connection with the conduct of the Billing Group or, to the extent any claim is
made against Billing or any of its Subsidiaries, the Telecommunications Group,
and which injuries, losses, liabilities, damages and expenses may arise out of
insured or insurable occurrences or events under one or more of the Shared
Policies; PROVIDED, HOWEVER, that nothing in this clause shall be deemed
to constitute (or to reflect) the assignment of the Shared Policies, or any of
them, to Billing and (b) the Billing Group Policies.


      Section 10.02.  POST-DISTRIBUTION DATE CLAIMS.  If, subsequent to the
Distribution Date, any person, corporation, firm or entity shall assert a claim
against Billing or any of its Subsidiaries with respect to any injury, loss,
liability, damage or expense incurred or claimed to have been incurred prior to
the Distribution Date in, or in connection with, the conduct of the Billing
Group Business or, to the extent any claim is made against Billing or any of its
Subsidiaries, the Telecommunications Group Business, and which injury, loss,
liability, damage or expense may arise out of insured or insurable occurrences
or events under one or more of the Shared Policies, USLD shall at the time such
claim is asserted be deemed to assign, without need of further documentation, to
Billing any and all rights of an insured party under the applicable Shared
Policy with respect to such asserted claim, specifically including rights of
indemnity and the right to be defended by or at the expense of the insurer;
PROVIDED, HOWEVER, 


                                        27 

<PAGE>


that nothing in this sentence shall be deemed to constitute (or to reflect) 
the assignment of the Shared Policies, or any of them, to Billing.

      Section 10.03.  ADMINISTRATION AND RESERVES.  (a)  Notwithstanding the
provisions of Article III, but subject to any contrary provisions of any Related
Agreement, from and after the Distribution Date:

            (i)   Billing shall be entitled to any reserves established by USLD
      or any of its Subsidiaries, or the benefit of reserves held by any
      insurance carrier, with respect to the Billing Group Liabilities; and

            (ii)  USLD shall be entitled to any reserves established by USLD or
      any of its Subsidiaries, or the benefit of reserves held by any insurance
      carrier, with respect to the Telecommunications Group Liabilities.

      (b)   INSURANCE PREMIUMS.  Billing shall have the right but not the
obligation to pay the premiums, to the extent that USLD does not pay premiums
with respect to Telecommunications Group Liabilities (retrospectively-rated or
otherwise), with respect to Shared Policies and the Billing Group Policies, as
required under the terms and conditions of the respective Policies, whereupon
USLD shall forthwith reimburse Billing for that portion of such premiums paid by
Billing as are attributable to the Telecommunications Group Liabilities.  USLD
shall provide continued coverage under its director and officer liability
insurance policy for a period of not less than five years for acts that took
place or were alleged to have taken place prior to the Distribution Date
covering persons who were directors and officers of USLD prior to the
Distribution Date.  Fifty percent of the additional premiums, if any, for such
coverage shall be reimbursed by Billing within 15 days of the Distribution Date.
Such coverage for director and officer liability insurance shall not be
discontinued by USLD without the consent of Billing, which consent shall not be
unreasonably withheld.

      (c)   ALLOCATION OF INSURANCE PROCEEDS.  Insurance Proceeds received
with respect to claims, costs and expenses under the Policies shall be paid to
Billing with respect to the Billing Group Liabilities and to USLD with respect
to the Telecommunications Group Liabilities.  Payment of the allocable portions
of indemnity costs of Insurance Proceeds resulting from the liability policies
will be made to the appropriate party upon receipt from the insurance carrier.
In the event that the aggregate limits on any Shared Policies are exceeded, the
parties agree to provide an equitable allocation of Insurance Proceeds received
after the Distribution Date based upon their respective bona fide claims.  The
parties agree to use their best efforts to cooperate with respect to insurance
matters.

      Section 10.04.  AGREEMENT FOR WAIVER OF CONFLICT AND SHARED DEFENSE.  In
the event that Insured Claims of both Billing and USLD exist relating to the
same occurrence, Billing and USLD agree to jointly defend and to waive any
conflict of interest necessary to the conduct of that joint defense.  Nothing in
this paragraph shall be construed to limit or otherwise alter in any way the
indemnity obligations of the parties to this Agreement, including those created
by this Agreement, by operation of law or otherwise.

      (b)   Such arbitration shall be conducted in Bexar County, Texas.

      (c)   Any judgment upon the award rendered by the arbitrators may be
entered in any court having jurisdiction thereof.  The arbitrators shall not,

relief before such court (i) to restrain the other party from breaching this
Agreement or (ii) for specific enforcement of this Section 11.13.  The parties
agree that any legal remedy available to a party with respect to a breach of
this Section 11.13 will not be adequate and that, in addition to all other legal
remedies, each party is entitled to an order specifically enforcing this Section
11.13.

      (e)   The Parties hereby consent to the jurisdiction of the federal courts
located in the State of Texas for all purposes under this Agreement.

      (f)   Neither party nor the arbitrators may disclose the existence or

written consent of both parties, except as required to fulfill applicable
disclosure and reporting obligations, or as otherwise required by law.

      (g)   Each party shall bear its own costs incurred in the arbitration.  If
either party refuses to submit to arbitration any dispute required to be
submitted to arbitration pursuant to this Section 11.13, and instead commences
any other proceeding, including, without limitation, litigation, then the party
who seeks enforcement of the obligation to arbitrate shall be entitled to its
attorneys' fees and costs incurred in any such proceeding.

      Section 11.14.  PROMPT ACTION.   Where the terms of this Agreement
require payment or action "as promptly as possible," "as soon as practicable,"

      Section 11.15.  APPLICABILITY TO RELATED AGREEMENTS.  To the extent that

governed by the applicable provisions in this Agreement.

a Nonqualified Award of a Billing Stock Option to purchase a number of shares of
Billing Common Stock under the Billing 1996 Comprehensive Stock Plan equal to
the number of shares of USLD Common Stock purchasable under the Existing USLD
Stock Option and (2) each non-employee director of USLD that is a grantee of


                                     -10-
<PAGE>



an Existing USLD Stock Option under the USLD 1993 Non-Employee Director Plan, a
Billing Stock Option to purchase a number of shares of Billing Common Stock
under the Billing 1996 Comprehensive Stock Plan equal to the number of shares of
USLD Common Stock purchasable under the Existing USLD Stock Option. The Billing
Stock Options will be subject to the same terms and conditions of the
corresponding Existing USLD Stock Options, except that the exercise price of the
Billing Stock Options shall be set as described in paragraph 2.4(c)(iii) and the
Distribution shall not be deemed a termination of employment of any Retained
Employee or Billing Employee for purposes of the USLD 1990 Employee Stock Option
Plan or the Billing 1996 Comprehensive Stock Plan.  The Existing USLD Stock
Options shall remain in effect with the same terms and conditions, including
that the same number of shares of USLD Common Stock shall be purchasable upon
exercise thereof, except that the exercise price of the Existing USLD Stock
Options shall be adjusted pursuant to paragraph 2.4(c)(iii).

      (iii) ADJUSTMENT AND SETTING OF EXERCISE PRICES.  The adjusted exercise
price (the "Adjusted USLD Option Exercise Price") of each Existing USLD Stock
Option and the exercise price of the related Billing Stock Option shall be as
follows.  The Adjusted USLD Option Exercise Price shall equal the product of (1)
the exercise price of the Existing USLD Stock Option multiplied by (2) the ratio
of (a) the Post Conversion Stock Price of USLD Common Stock to (b) the sum of
(x) the Post Conversion Stock Price of the USLD Common Stock plus (y) the Post
Conversion Stock Price of the Billing Common Stock.  The exercise price of the
related Billing Stock Option shall equal the product of (1) the exercise price
of the related Existing USLD Stock Option multiplied by (2) the ratio of (a) the
Post Conversion Stock Price of Billing Common Stock to (b) the sum of (x) the
Post Conversion Stock Price of the Billing Common Stock plus (y) the Post
Conversion Stock Price of the USLD Common Stock.

      (d)   COMMUNICATION REGARDING TERMINATION OF EMPLOYMENT, VESTING AND 
LAPSE OF RESTRICTIONS.  USLD shall promptly notify Billing of the termination 
of employment of any Retained Employee holding Billing Stock Options or 
restricted shares of Billing Common Stock and of any amendment to an Existing 
USLD Stock Option held by a Retained Employee holding a related Billing Stock 
Option.  Billing shall promptly notify USLD of the termination of employment 
of any Billing Employee holding an Existing USLD Stock Option or restricted 
shares of USLD Common Stock and of any amendment to a Billing Stock Option 
held by a Billing Employee holding a related Existing USLD Stock Option.  
Such notices with respect to termination shall specify the date of 
termination, the reason for termination (e.g. for cause, without cause, upon 
a change of control, etc.), whether the termination is with or without 
written consent and that the impact that such termination has on any 
outstanding grant or award of options on restricted shares. Such notices 
with respect to  amendments to an Existing USLD Stock Option or Billing Stock 
Option shall specify the amendment, the name of the Retained Employee or 
Billing Employee, as applicable, and such other information as the other 
party shall reasonably require. USLD agrees that each Existing USLD Stock 
Option held by a Billing Employee whose related Billing Stock Option is 
amended following the Distribution Date shall be deemed amended and shall be 
amended to the same extent as the related Billing Stock Option is amended 
without further action. Billing agrees that each Billing Stock Option held by 
a Retained Employee whose related Existing USLD Stock Option is amended 
following the Distribution Date shall be deemed amended and shall be amended 
to the same extent as the related Existing USLD Stock Option is amended 
without further action.


      (e)   CHANGE IN CONTROL.  Each Existing USLD Stock Option agreement 
provides or will provide, and each relating Billing Stock Option agreement 
will provide, that (a) upon a change of control (as defined in the 
applicable stock option agreement) of USLD, all nonvested Existing USLD Stock 
Options, whether held by a Retained Employee or a Billing Employee, and all 
nonvested Billing Stock Options held by Retained Employees shall immediately 
vest, and (b) upon a change of control (as defined in the applicable stock 
option agreement) of Billing, all nonvested Billing Stock Options, whether 
held by a Retained Employee or a Billing Employee, and all nonvested Existing
USLD Stock Options held by Billing Employees shall immediately vest.


      (f)  DETERMINATION OF CONSENT TO TERMINATION OF EMPLOYMENT OF BILLING 
EMPLOYEES UNDER USLD EMPLOYEE STOCK PLAN.  USLD agrees that with respect to 
Billing Employees who hold USLD Stock Options under the USLD 1990 Employee 
Stock Plan, for purposes of Section 14 of the USLD 1990 Employee Stock Plan, 
the giving or withholding of consent to the termination of employment of a 
Billing Employee shall be as determined by Billing and stated in the notice 
of termination provided by Billing to USLD as required by Section 2.4(d) 
above.

plan in which they were enrolled prior to the Distribution.  The medical/dental

HMOs and PPOs providing coverage) to be responsible for, the administration of
the continuation coverage requirements imposed by Code Section 4980B and ERISA
Sections 601 through 608 as they relate to any USLD Current Qualified

      (d)   In the event that subsequent to the Distribution Date, refunds are
received from or additional premium adjustments become payable to carriers
providing health or medical insurance where such amounts are the result of
actual experience differing from that used to compute premiums for any periods
prior to the Distribution Date, such refunds or obligations will be shared
between USLD and Billing based on the following formula.  Billings share will
equal the percentage represented by the average number of Billing employees
during the period to which the refund or obligation relates divided by the
average total of Billing and USLD employees during such period.  USLD's share
will equal  the percentage represented by the average number of USLD employees
during the period to which the refund or obligation relates divided by the
average total of Billing and USLD employees during such period.

      2.7   VACATION AND SICK PAY LIABILITIES.

      (a)   DIVISION OF LIABILITIES.  Effective on the Distribution Date, USLD
shall retain, as to the Retained Employees, and, Billing shall assume, as to the
Billing Employees, all accrued liabilities (whether vested or unvested, and
whether funded or unfunded) for vacation and sick leave in respect of such
employees as of the Cutoff Date.  USLD shall be solely responsible for the
payment of such vacation or sick leave to Retained Employees after the Cutoff
Date and Billing shall be solely responsible for the payment of such vacation or
sick leave to Billing Employees after the Cutoff Date. Each party shall provide
to its own Employees on the Distribution Date the same vested and unvested
balances of vacation and sick leave as credited to such Employee on the USLD
payroll systems on the Cutoff Date.  The preceding sentence shall not be
construed as in any way limiting the right of either USLD or Billing to change
its vacation or sick leave policies as it deems appropriate.

      (b)   FUNDED RESERVES.  Assets attributable to funded reserves for the
vacation or sick leave liabilities being divided in accordance with Section
2.7(a) (whether held in a trust, a voluntary employees beneficiary association,
or any other funding vehicle) shall be allocated in an appropriate and equitable
manner between USLD and Billing.

      2.8   PRESERVATION OF RIGHT TO AMEND OR TERMINATE PLANS.  Except as
otherwise expressly provided in Article 2, no provisions of this Agreement,
including, without limitation, the agreement of USLD or Billing, or any Retained
Subsidiary or Billing Subsidiary, to make a contribution or payment to or under
any Plan herein referred to for any period, shall be construed as a limitation
on the right of USLD or Billing or any Retained Subsidiary or Billing Subsidiary
to amend such Plan or terminate its participation therein which USLD or Billing
or any Retained Subsidiary or Billing Subsidiary would otherwise have under the
terms of such Plan or otherwise.  No provision of this Agreement shall be
construed to create a right in any employee or former employee, or dependent or
beneficiary of such employee or former employee, under a Plan which such person
would not otherwise have under the terms of the Plan itself.

      2.9   NOTICE.  USLD and Billing acknowledge that USLD and the Retained
Subsidiaries, on the one hand, and Billing and the Billing Subsidiaries, on the
other hand, may incur costs and expenses, including, but not limited to,
contributions to Plans and the payment of insurance premiums arising from or
related to any of the Plans that are, as set forth in this Agreement, the
responsibility of the other party hereto.  Accordingly, USLD (and any Retained
Subsidiary


                                     -13-
<PAGE>



responsible therefor) and Billing (and any Billing Subsidiary responsible
therefor) shall (i) give notice to the other party of the costs to be incurred
prior to payment and (ii) demand that the other party which has the obligation
to pay shall pay the cost and expense.

Statements), as described in Section 5 of Revenue Procedure 84-77, 1984-2 IRS
Cumulative Bulletin 753 ("Rev. Proc. 84-77").  Under this procedure Billing as

Individuals reflecting all wages paid and taxes withheld by both USLD as the
predecessor and Billing as the successor employer for the entire year during
which the Distribution takes place.  USLD shall provide all required Forms W-2

aforesaid agreement under Rev. Proc. 84-77, each business unit or business
operation of USLD shall be assigned to either USLD or Billing, depending upon
whether it is a Retained Business or a Billing Business, and each Retained
Individual or Billing Individual associated with such business unit or business
operation shall be assigned for payroll reporting purposes to USLD or Billing,
as the case may be.

      (b)   FORMS W-4 AND W-5.  Billing and USLD agree to adopt the
alternative procedure of Rev. Proc. 84-77 for purposes of filing IRS Forms W-4
(Employee's Withholding Allowance Certificate) and W-5 (Earned Income Credit
Advance Payment Certificate).  Under this procedure USLD shall provide to
Billing as the successor employer all IRS Forms W-4 and W-5 on file with respect
to each Billing Individual, and Billing will honor these forms until such time,
if any, that such Billing Individual submits a revised form.

      (c)   GARNISHMENTS, TAX LEVIES, CHILD SUPPORT ORDERS, QUALIFIED MEDICAL
CHILD SUPPORT ORDERS AND WAGE ASSIGNMENTS.  With respect to Employees with
garnishments, tax levies, child support orders, qualified medical child support
orders, and wage assignments in effect with USLD on the Cutoff Date, Billing
with respect to each Billing Individual shall honor such payroll deduction
authorizations or court or governmental orders applicable to Billing Plans, and

as specified by the court or governmental order that was filed with USLD.
Likewise, USLD with respect to each Retained Individual shall honor such payroll
deduction authorization or court or governmental orders applicable to USLD Plans
and will continue to make payroll deductions and payments to any authorized
payee, as specified by the court or governmental order that was filed with USLD.

      (d)   AUTHORIZATIONS FOR PAYROLL DEDUCTIONS.  Unless otherwise
prohibited or provided by this Agreement or another agreement entered into in
connection with the Distribution, or by a Plan document, with respect to
Employees with authorizations for payroll deductions in effect with USLD on the
Cutoff Date, Billing as the successor employer will honor such payroll deduction
authorizations relating to each Billing Individual, including, without
limitation, scheduled loan repayments to the 401(k) Retirement Plan and direct
deposit of payroll, bonus advances and types of authorized company receivables
usually collectible through payroll


                                     -14-

deductions, and shall not require that such Billing Individual submit a new
authorization to the extent that the type of deduction by Billing does not
differ from that made by USLD.

                         LABOR AND EMPLOYMENT MATTERS

      Notwithstanding any other provision of this Agreement or any other
Agreement between USLD and Billing to the contrary, USLD and Billing understand

      3.1   SEPARATE EMPLOYERS.  After the Distribution Date and the
separation of Employees into their respective companies, USLD and Billing will
be separate and independent employers.

      3.2   EMPLOYMENT POLICIES AND PRACTICES.  USLD and Billing may adopt,
continue, modify or terminate such employment policies, compensation practices,
retirement plans, welfare benefit plans, and other employee benefit plans or
policies of any kind or description, as each may determine, in its sole
discretion, are necessary and appropriate.

      3.3   CLAIMS.

      (a)   SCOPE.  This section is intended to allocate all liabilities for
employment-related claims involving USLD or Billing including, but not limited
to, claims against either or both USLD and Billing and their respective

employee benefit plans and plan administrators and fiduciaries; provided,
however, that this section shall not apply to any indemnification between the
parties for matters and services contemplated in that certain Transitional
Services and Sublease Agreement between the parties dated July 10, 1996 and

and hold harmless the other party under this Section 3.3 shall include the
following obligations of the party having such duty:  to provide a legal defense
and incur all attorneys' fees and litigation costs that may be associated with
such a defense; to pay all costs of settlement or judgment where the
indemnifying party has the full duty to do so or to pay the full percentage of
the party's share when the duty is only a percentage of the full settlement or
judgment; and to hold harmless from all claims and costs that may be asserted
with or arising from the duty of the indemnifying party to defend and indemnify.



                                     -15-

occurring on or before the Cutoff Date.

      (e)   DISTRIBUTION AND OTHER JOINT LIABILITY CLAIMS.  Where
employment-related claims alleging or involving joint and several liability
asserted against USLD and Billing are not separately traceable to liabilities
relating to Retained Individuals or Billing Individuals, any liability shall be
appointed between USLD and Billing in accordance with the percentage that each
party's Employees represents of the combined total number of Employees of both
parties, as described below.  The percentage of the liability assumed by USLD
shall equal the ratio of (i) the total number of Retained Employees on the
Distribution Date to (ii) the combined total number of Retained Employees and
Billing Employees on such date.  The percentage of the liability assumed by
Billing shall equal the ratio of (i) the total number of Billing Employees on

harmless the other to the extent of the indemnifying party's apportioned

claims arising from acts occurring after the Distribution and division of the
Employees between the parties and not relating to, arising from, or in
connection with the Distribution will be the sole responsibility of USLD as to
Retained Individuals and of Billing as to Billing Individuals.  Each Company
will indemnify, defend, and hold harmless the other from employment-related
claims of the other company.

      3.4   FUNDING OF PLANS.  Without limitation to the scope and application
of Section 3.3, any claims by or on behalf of Employees or any federal, state or
local government agency for alleged underfunding of, or failure to make payments
to, health and welfare funds based on acts or omissions occurring on or before
the Cutoff Date or arising from or in connection with the Distribution, will be
the sole responsibility of each party as to its own employees (i.e., USLD with
respect to Retained Individuals and Billing with respect to Billing
Individuals), and the responsible party will indemnify, defend, and hold
harmless the other from any such claims.

      3.5   NOTICE OF CLAIMS.  Without limitation to the scope and application
to each party in the performance of its duties under Section 3.3 and 3.4 herein,
each party will notify in writing and consult with the other party prior to
making any settlement of an employee claim, for the purpose of avoiding any
prejudice to such other party arising from the settlement.

      3.6   ASSUMPTION OF EMPLOYMENT TAX RATES.  Changes in state unemployment
tax experience as of the Cutoff Date shall be handled as follows:  In the event
an option exists to allocate state unemployment tax experience of USLD, the USLD

aggregate unemployment tax costs for both USLD and


                                     -16-

combined.

create any third party contractual or other common law rights.  No person shall
be deemed a third-party beneficiary of the agreement between Billing and USLD.

      3.11  ATTORNEY-CLIENT PRIVILEGE.  Consistent with the provisions of the
Distribution Agreement, the provisions herein requiring either party to this

periods ending on or before the Closing Date;

                  (2)   all U.S. and foreign Tax and Information Returns of the

Periods that are not required to be filed for periods ending on or before the
Closing Date;

                  (3)   all U.S. and foreign Tax and Information Returns of the
USLD Group and any USLD Member for all Straddle Periods and Post-Closing Taxable
Periods; and

                  (4)   all U.S. and foreign Tax and Information Returns not
otherwise required to be filed by USLD or Billing pursuant to this Section
2.1(a) and Section 2.1(b).

            (b)   BY BILLING.  Billing shall prepare and timely file (or cause

other information reasonably requested by the other party in connection with the
preparation of such Tax and Information Returns promptly after such request.

      2.3 TAXABLE YEAR.  Billing and USLD agree that, for Tax purposes, (i)
for the period ending on the Closing Date, the Billing Member shall be included
in the consolidated federal Tax Return of the Pre-Spin-Off Group for the Taxable

      2.4 STRADDLE PERIOD TAXES.

            (a)   For purposes of this Agreement, Taxes shall be allocated
between the Pre- and Post-Closing Straddle Periods, in USLD's reasonable
judgment with the consent of the appropriate Billing personnel, which shall not
be unreasonably withheld, in the following manner:  (A) to the extent not
impractical, Taxes shall be allocated on the basis of the actual taxable income
for each such period, determined by closing the books of the Pre-Spin-Off Group
at the close of business on the Closing Date; and (B) to the extent that such an
allocation based on a closing of the books is impractical, USLD shall be
authorized to allocate Taxes based on rounding to the next nearest accounting
period-end.

            (b)   USLD shall pay to Billing within fourteen (14) days after
receipt of an executed Straddle Period Tax Return prepared by Billing pursuant
to Section 2.1(b), the excess of any amount so allocated (based on the amount of
Tax shown on such Tax Return) to the Pre-Closing Straddle Period over the amount
of any estimated Taxes previously paid by any Pre-Spin-Off Member to the
relevant Taxing Authority prior to the Closing Date; or Billing shall pay to
USLD within fourteen (14) days after the filing of such Tax Return the excess of
the amount of any estimated Taxes previously paid by any Pre-Spin-Off Member to
the relevant Taxing Authority prior to the Closing Date over the amount so
allocated to such Period.

      2.5 PAYMENT OF TAXES.  USLD shall pay (i) all Taxes shown to be due
and payable on all Tax Returns filed by (A) USLD pursuant to Section 2.1(a)
hereof and (ii) subject to Section 3, all Taxes that shall thereafter become due
and payable with respect to all Tax Returns filed pursuant to Sections 2.1(a) as
a result of a Final Determination; PROVIDED, HOWEVER, that Billing shall
reimburse USLD within fourteen (14) days of receipt of notification from USLD
for the amount of Net Taxes that are attributable to any Billing Member on a
Separate Return Basis for all Pre-Closing Taxable Periods that shall thereafter
become due and payable as a result of a Final Determination.  Billing shall pay
all Taxes attributable to all Tax Returns filed by Billing pursuant to Section
2.1(b) hereof.

      2.6 AMENDMENTS TO TAX RETURNS.  No Tax Returns for any Pre-Closing
Taxable Periods filed by USLD may be amended without USLD's and Billing's

            (a)   USLD shall be entitled to any refund of Taxes and any Tax
Benefits realized as a result of a Final Determination with respect to all Tax
Returns filed by USLD pursuant to Section 2.1(a); provided, however, that USLD
shall reimburse Billing for the amount of any Tax Benefit attributable to any
Billing Member for all Pre-Closing Taxable Periods which arises as a result of a
Final Determination.  (Any refund resulting from the application of a net
operating loss carryback is deemed attributable to the corporation generating
such net operating loss.)  Billing shall be entitled to any refund with respect
to all Tax Returns filed by Billing pursuant to Section 2.1(b).  Any such
refunds attributable to a Straddle Period shall be allocated

between the Pre-Closing Straddle Period and Post-Closing Straddle Period on a
basis consistent with the method used to allocated the Tax liability for such
Straddle Period.  With respect to Straddle Period Tax Returns prepared by
Billing pursuant to Section 2.1(b), USLD shall be entitled to any refund
attributable to a Pre-Closing Straddle Period.

            (b)   If USLD or any USLD Member receives a Tax refund or Tax
Benefit to which Billing or any Billing Member is entitled pursuant to this
Agreement, USLD shall pay (in accordance with Section 4) the amount of such Tax
refund or Tax Benefit to Billing within fourteen (14) days of receipt thereof.

            (c)   Except as otherwise provided in this Agreement, if Billing or
any Billing Member receives a Tax refund or Tax Benefit to which USLD or any
USLD Member is entitled pursuant to this Agreement, Billing shall pay (in
accordance with Section 4) the amount of such Tax refund or Tax Benefit
(including any interest received thereon) to USLD within fourteen (14) days of
receipt thereof.

      2.8 CARRYBACKS.  Neither Billing nor USLD shall file any carryback
claim for federal Taxes or state, local or foreign Taxes in a Combined
Jurisdiction for the Billing Group or any Billing Member or the USLD Group or
any USLD Member into a Pre-Closing Taxable Period without the prior written
consent of USLD or Billing, as applicable, which shall not be unreasonably
withheld.

      2.9 PENDING TAX AUDIT.  Notwithstanding any provision to the contrary 
in this Agreement, the taxes, refunds, penalties, interest and attorney and 
accountant fees arising with respect to the currently pending Internal 
Revenue Service aduit of USLD's taxable years ending September 30, 1992, 1993 
and 1994 (the "Pending Audit") shall be governed by the provisions of this 
Section 2.9.

            (a)   Any tax deficiency payable as a result of the Pending Audit 
(whether by settlement with the Internal Revenue Service or by final 
judgement in a litigation of the issues arising in such Pending Audit) plus 
related penalties and interest shall be allocated to and paid by USLD and 
Billing, respectively, in proportion to the respective market capitalization 
of their issued and outstanding stock as of the Closing Date based on the per 
share price of USLD common stock and Billing common stock, as applicable, 
determined by using the average of the closing sales price per share of that 
common stock on the NASDAQ National Market for each of ten consecutive 
trading days beginning with the including the Closing Date.

            (b)   Any tax refund payable as a result of the Pending Audit 
attributable to adjustments to depreciation deductions will be distributed to 
USLD and Billing, respectively, depending on which company owns after the 
Closing Date the assets with respect to which the depreciation deductions 
were adjusted and in proportion to such respective adjustments.

            (c)   Any interest payable with respect to the refunds described 
in (b) above will be payable first to USLD as reimbursement for amounts 
previously paid or accrued for attorney and accountant fees with respect to 
the Pending Audit and any remaining amounts shall be allocated between the 
companies in the same proportion as the refund payments under (b) above.

            (d)   All attorney and accountant fees with respect to the 
Pending Audit shall be paid or accrued by USLD.

      SECTION 3. INDEMNIFICATION.

      3.1 BY USLD.

            (a)   TAXES.  Except as provided in Section 3.2, USLD shall

and (ii) all Net Taxes attributable to any Billing Member on a Separate Return
Basis for all Pre-Closing Taxable Periods that shall thereafter become due and

affected or impaired thereby.  It is hereby stipulated and declared to be the

a waiver thereof, nor shall any single or partial exercise of any right preclude
any other or further exercise of the same or any other right, nor shall any
waiver of any right with respect to any occurrence be construed as a waiver of
such right with respect to any other occurrence.

permitted assigns, and shall survive any acquisition, disposition or other
corporate restructuring or transaction involving either party.

      7.10 NO THIRD-PARTY BENEFICIARIES.  This Agreement is solely for the
benefit of the parties to this Agreement and their respective Affiliates and
should not be deemed to confer upon


                                        11

agreements and stipulations of Billing hereinafter expressed, hereby leases, 
demises and rents to Billing (i) approximately 6,200 square feet of the space 
occupied by USLD at Suite 800, 9311 San Pedro, San Antonio, Texas, together 
with the right to use the hallways, restrooms and common areas of Suite 800 
and the 8th floor (the "8th Floor Subleased Premises") more fully described 
in EXHIBIT C attached hereto and made a part hereof for all purposes and (ii) 
approximately 18,633 square feet of the space occupied by Billing at Suite 
400, 9311 San Pedro, San Antonio, Texas, together with the right to use 
hallways, restrooms and common areas of Suite 400 and the 4th floor (the "4th 
Floor Subleased Premises") more fully described in EXHIBIT D attached hereto 
and made a part hereof for all purposes (collectively, the 4th Floor 
Subleased Premises and the 8th Floor Subleased Premises are referred to as 
the "Subleased Premises").  The Subleased Premises are situated in the Nowlin 
building (the "Building") located in the city of San Antonio in Bexar County, 
Texas.  The Building is located on a tract of land situated in said county, 
which land is more fully described in EXHIBIT E attached hereto and made a 
part hereof for all purposes.



           (b)    To have and to hold the Subleased Premises, together 
with the appurtenances thereto, unto Billing beginning on the date of the 
Distribution until terminated as provided in Section 4, to be used and 
occupied by Billing for general office purposes. 



            (c)   In consideration of this sublease, Billing shall pay to 
USLD at the address stated herein the sum of (i) approximately $6,500 per 
month for the 8th Floor Subleased Premises and (ii) approximately $19,600 per 
month for the 4th Floor Subleased Premises in legal tender of the United 
States of America, payable, without demand, in advance on or before the 1st 
day of each calendar month during the full term hereof; provided, however, 
that if the term of this sublease commences on a date other than the 1st day 
of the calendar month, the first rental payment to be made on said 
commencement date shall be the rental for one calendar month plus the 
prorated rental remainder for the calendar month in which the subleased term 
commences.



            (d)   Insofar as the provisions of that certain Office Lease 
Agreement dated September 29, 1988 by and between Nowlin Building 
Partnership, Ltd., as Landlord, and USLD, as Tenant, as amended (the "Main 
Lease"), do not conflict with the specific provisions herein contained, they 
and each of them are incorporated into this Agreement as fully as if 
completely rewritten, and Billing agrees to be bound to USLD by all of the 
terms of the Main Lease and to assume and perform all of the obligations and 
responsibilities of USLD pursuant to the Main Lease and to indemnify and hold 
harmless USLD from any claim or liability under the Main Lease except for the 
payment of rental by USLD to the Landlord as provided in the Main Lease. The 
relationship between Billing and USLD hereunder shall be the same as that 
between USLD and the Landlord under the Main Lease.

or otherwise, the other may terminate the services portion of this Agreement 
upon ten (10) days' written notice to the Defaulting Party specifying the

      billing and collection.

SECTION 2.  SCOPE OF AGREEMENT.

Customer hereby agrees to purchase from BICI the services described in Section 3
herein, and BICI agrees to provide such services at the time and in the manner,
and subject to the terms and upon the conditions, set forth herein.  Customer
agrees that BICI shall be the EXCLUSIVE source for LEC billing and information
management services in the United States and Canada for the billing telephone
companies listed in Exhibit A, attached hereto.  However, nothing contained
herein shall be interpreted to prohibit Customer from contracting directly with
any LEC for its own direct LEC billing and collection agreement, provided that
Customer shall notify BICI of its intent at least sixty (60) days prior to
activation of such agreement.  As BICI enters into billing and collection
arrangements with additional LECs, BICI will provide billing and information
management services to Customer for such LECs on the same terms and conditions
as contained herein.

SECTION 3.  BILLING SERVICES.
      
      (a)   SUBMISSION OF EMI BILLING RECORDS.  Customer shall submit to BICI 
its EMI Billing Records for its qualifying MTS calls for BICI to submit to 
each LEC under contract with BICI.  Customer shall be responsible for 
submitting to BICI EMI Billing Records that contain adequate information so 
that BICI and the LECs can process such EMI Billing Records.  Customer shall 
submit these EMI Billing Records to BICI once per week, except when Customer 
cannot satisfy BICI's minimum volume requirements as described in paragraph 
7.(f), in which case Customer shall submit its EMI Billing Records at least 
once per month.  The cost of these submissions shall be borne by Customer.  
The date BICI receives Customer's EMI Billing Records will be, for those 
records, the "Submission Date."

                                        3 
<PAGE>



      (b)   BICI'S EDITS AND SCREENS.  Upon receipt of Customer's EMI Billing 
Records, BICI will promptly process Customer's EMI Billing Records through 
BICI's computer edits and screens.  Those EMI Billing Records that pass 
BICI's edits and screens shall be "Valid EMI Billing Records."  Those EMI 
Billing Records that do NOT pass BICI's edits and screens shall be "BICI 
Rejected Records," and shall be returned to Customer.
      
      (c)   SUBMISSION TO LECS.  Promptly after receipt of Customer's EMI 
Billing Records (within five (5) Business Days after such receipt for the 
RBOCs and GTE, or within ten (10) Business Days after such receipt for 
Independent Telephone Companies), BICI will submit Customer's Valid EMI 
Billing Records to the appropriate LECs.
      
      (d)   PURCHASE BY LEC.  Each LEC shall be responsible, to the extent
required by its agreement with BICI, to purchase Customer's Valid EMI Billing
Records.

      (e)   BILLING AND COLLECTION BY LEC.  Each LEC shall be responsible, for
such Valid EMI Billing Records purchased by the LEC, for the billing and
collection of the revenue, for Customer's qualifying MTS calls, from End Users
residing within the applicable billing area of such LEC.
      
      (f)   PRINTING OF CUSTOMER'S NAME ON END USER'S LEC TELEPHONE BILL: 
Wherever possible, BICI will use its best efforts to cause each Billing 
Telephone Company to print Customer's name, along with the associated Valid 
EMI Billing Records, on each End User's telephone bill.  Customer 
acknowledges that where the Billing Telephone Companies do not provide this 
service, Customer's name shall not appear on the End User's telephone bill.

SECTION 4:  LEC PAYMENTS, FEES AND CHARGES:
      
      (a)   PAYMENT BY LECS:  Each LEC shall make payments to BICI for Valid 
EMI Billing Records purchased from Customer in accordance with the LEC's 
billing and collection agreement with BICI.
      
      (b)   AMOUNT PAID BY LECS:  The LEC shall pay to BICI the gross amount 
of Valid EMI Billing Records purchased by the LEC LESS the then-applicable 
fees, charges, charge backs, credits and adjustments as prescribed in its 
billing and collection agreement with BICI.
       
       (c)  LEC FEES, CHARGES, CHARGE BACKS, CREDITS AND ADJUSTMENTS: 
Customer acknowledges and understands that BICI is and will be bound by the 
terms of its billing and collection agreement with each LEC with respect to 
each LEC's right to deduct or to reduce its collectible funds for: (i) the 
amount charged by each LEC for processing, billing and collecting Customer's 
Valid EMI Billing Records ("LEC Processing Fees"), (ii) any Unbillable 
Records, (iii) any Post-Billing Adjustments or Credits provided to End Users, 
(iv) any reserve for anticipated Uncollectible Amounts ("Bad Debt Holdback 
Reserve"), and (v) any LEC Bad Debt "true-ups" (i.e. periodic true-ups 
between the Bad Debt Holdback Reserve and the actual Uncollectible Amounts 
realized by the LECs).  In addition, Customer shall be responsible for any 
data transmission and distribution fees for delivering or receiving 
Customer's EMI Billing Records and for any other LEC charges specifically 
related to billing and collecting Customer's EMI Billing Records.  Customer 
further agrees that payment of all amounts described in this paragraph 4.(c)

                                        4 
<PAGE>



shall be its sole responsibility and that BICI may withhold such amounts from 
payments to Customer.  Should such amounts exceed the amounts due to 
Customer, such amounts shall be due and payable by Customer to BICI within 
ten (10) Business Days of notification by BICI of any amounts due.  A 
schedule setting forth BICI's contractual average LEC Processing Fees for 
each LEC is attached hereto as Exhibit B hereto.

      (d)   BAD DEBT HOLDBACK RESERVE:  BICI will holdback or cause the LECs 
to holdback an amount estimated to be sufficient to set-off any Uncollectible 
Amounts that may be determined after the date BICI makes its final payment to 
Customer for Customer's Valid EMI Billing Records billed and collected by the 
LEC.  Any Bad Debt Holdback Reserve withheld by the LEC shall be passed 
through to Customer on the same percentage or the same amount as BICI was 
assessed by the individual LECs.  However, once sufficient data becomes 
available to BICI from the LECs to enable BICI to determine a specific Bad 
Debt history attributable to Customer, the Bad Debt Holdback Reserve rate 
shall be based on Customer's specific historical Uncollectible Amounts.  A 
schedule setting forth the past twelve months' average Bad Debt Holdback 
Reserve withheld by each LEC is attached hereto, for your reference, as 
Exhibit G.

      (e)   MONTHLY LEC BAD DEBT TRUE-UP.  Between six and eighteen (6 - 18) 
months after BICI submits Customer's EMI Billing Records to the LECs for 
billing and collection, the LECs will determine the actual amounts collected 
from the End Users and true-up the difference between this amount and the 
face amount of Customer's Valid EMI Billing Records purchased by the LEC.  
BICI will provide Customer monthly reports on Bad Debt true-ups for these 
differences.  If the amount of these true-ups is "in favor" (positive) of 
Customer, BICI will remit such amount to Customer when BICI receives the 
true-up amount from the LECs.  If the amount of these true-ups is "not in 
favor" (negative) of Customer, BICI will withhold such amounts from the next 
scheduled payment due to Customer.  If the amounts due to Customer are not 
sufficient to satisfy such true-up amounts, such amounts shall be due and 
payable by Customer to BICI within ten (10) Business Days of notification by 
BICI of any amounts due.

      (f)   LEC PROCESSING FEE CALCULATION.  Each calendar month BICI will 
determine the number of End User bills (renderings) that were or will be 
required to bill all of BICI's similarly situated customer's Valid EMI 
Billing Records submitted to BICI during that month and the average number of 
Valid EMI Billing Records contained on each End User's bill.  BICI will then 
multiply these quantities by its contractual LEC Processing Fee schedules for 
each LEC to calculate the "Average LEC Processing Fees" for each LEC.  
Exhibit B, attached hereto, contains the Average LEC Processing Fees for each 
LEC for the date thereof.  BICI will then multiply this Average LEC 
Processing Fee for each LEC by the number of Customer's Valid EMI Billing 
Records submitted to each LEC to calculate Customer's LEC Processing Fees.  
These Average LEC Processing Fees will also include any data transmission 
fees, distribution fees, programming fees and any other charges directly 
associated with billing Customer's Valid EMI Billing Records.

      (g)   END USER INQUIRY AND REBATE.  Primary End User inquiry, 
investigation and rebate policies are set forth in Exhibit F attached hereto. 
Customer shall be responsible for payment of all Post-Billing Adjustments and 
Credits provided to End Users by either the LEC or BICI.  Such amounts may be 
deducted weekly from the amounts due to Customer.  If the amount due to 
Customer is not sufficient to satisfy these amounts, then Customer shall pay 
BICI such amount

                                        5 
<PAGE>



as is required to satisfy these amounts within ten (10) Business Days of
notification by BICI of any amounts due.

      (h)   REJECTED RECORDS.  Those EMI Billing Records that fail BICI's 
edits and screens and not submitted to the LECs for billing and collection, 
BICI Rejected Records, shall be returned to Customer at no charge.  
Unbillable Records rejected by the LEC, through no fault of BICI, shall be 
charged the same BICI Processing Fees as described in Exhibit C attached 
hereto.
      
      (i)   RESUBMITTED EMI BILLING RECORDS:  Unbillable Records which are 
resubmitted to the LECs for billing and collection shall be charged the 
standard BICI Processing Fees as described in Exhibit C attached hereto.

SECTION 5.  BICI BILLING SERVICE FEES, CHARGES AND CHARGE BACKS.

In addition to the LEC Processing Fees, charges, charge backs, credits and 
adjustments set forth in Section 4, Customer agrees to pay to BICI and BICI 
may deduct from amounts collected by the LECs on behalf of Customer and paid 
to BICI, the following BICI billing service fees, charges, charge backs, 
credits and assessments:

      (a)   A billing and information management service fee, the BICI 
Processing Fee, for each Valid EMI Billing Record submitted to the LECs for 
billing and collection by BICI, as specified in Exhibit C attached hereto;
      
      (b)   An End User inquiry, investigation and rebate fee for each Valid 
EMI Billing Record submitted to the LECs for billing and collection by BICI, 
as specified in Exhibit C attached hereto;
      
      (c)   Any Post-Billing Adjustment or Credit amounts refunded to End 
Users by BICI's customer service inquiry and investigation activities, along 
with any LEC charges associated with making such refunds to End Users;

      (d)   A charge, as specified in Exhibit C attached hereto, for any 
submission of EMI Billing Records that contains less than the minimum volume 
requirements of BICI for each "library code";

      (e)   An additional End User inquiry, investigation and rebate fee, as 
described in Exhibit C attached hereto, for each inquiry that exceeds one 
percent (1%) of the number of Valid EMI Billing Records for each library code 
processed by BICI on behalf of Customer each month; and

      (f)   ACCOUNTS RECEIVABLE RECONCILIATION SYSTEM - FASTRACK:  Customer 
shall pay to BICI an initial, one-time fee, as described in Exhibit C 
attached hereto, for BICI's accounts receivable reconciliation system known 
as FASTRACK.

As collateral for all obligations now existing or hereafter arising from 
Customer to BICI, Customer hereby grants to BICI a security interest in all 
the following property of Customer, whether now owned or hereafter acquired 
or created, and all proceeds and products thereof:

                                        6 
<PAGE>



      (a)   All amounts paid, and all amounts owing, by each LEC to BICI on
accounts for Customer's EMI Billing Records;

      (b)   All accounts owing from an End User to Customer arising from
services which give rise to Customer's EMI Billing Records;

      (c)   All amounts deposited by Customer with BICI pursuant to paragraph
13.(b) hereof; and

      (d)   all amounts owing and all amounts to be owing from BICI to Customer.

SECTION 6.  PAYMENTS TO CUSTOMER.

      (a)   DETERMINATION OF AMOUNT DUE TO CUSTOMER.  BICI will determine the
amount collected by each LEC for Customer's Valid EMI Billing Records and deduct
the then-applicable fees, charges, charge backs, credits and adjustments of the
LECs and BICI.  If the amount due to Customer is not sufficient to satisfy these
fees, charges, charge backs, credits and adjustments, then Customer shall pay
this difference to BICI within ten (10) Business Days of notification by BICI of
any amounts due.

      (b)   RESERVES AND TRUE-UPS FOR UNBILLABLE RECORDS:  BICI will reserve an
amount, from one month to the next, that is equal to Customer's prior history
for Unbillable Records.  BICI will recalculate Customer's historical experience
quarterly from its prior three months results.  Until such history can be
determined for Customer, BICI will reserve two and one-half percent (2.5%) from
the amount due to Customer.  BICI will true-up this reserve each month when the
information becomes available from the LECs.  BICI will then return excess
amounts to Customer or withhold additional amounts as may be required to satisfy
these liabilities from the amounts due to Customer.

      (c)   PAYMENT SCHEDULES:  BICI will advance to Customer the estimated
amount determined under paragraph 6.(a) above within seven (7) Business Days of
receipt by BICI of any funds from a LEC for Customer's EMI Billing Records;
PROVIDED, HOWEVER, that if Customer has ceased doing business for five (5)
Business Days, is the subject of a bankruptcy proceeding, or a receiver, trustee
or custodian is appointed over substantially all of Customer's assets, or if
Customer fails to make any deposit required under paragraph 13.(b), or if BICI
has reasonable grounds to believe that the fees, charges, charge backs, credits
and adjustments to Customer may exceed any amount owing or to become owing from
BICI to Customer, BICI may withhold payments to Customer until all such amounts
have been determined and deducted from the amount owing to Customer.  If the
amount owing to Customer is determined not sufficient to satisfy these fees,
charges, charge backs, credits and adjustments, then Customer shall pay the
difference to BICI within ten (10) Business Days of notification by BICI of any
amount due.

      (d)   METHOD OF PAYMENT:  BICI will make all advance payments and final
payments due to Customer, using ACH wire transfer, each Tuesday or the first
Business Day following Tuesday should Tuesday not fall on a Business Day based
on the schedule described in paragraph 6.(c) herein.


                                        7 
<PAGE>



      (e)   ACCOUNTING FOR FUNDS:  Funds received from the LECs for Customer's
Valid EMI Billing Records, less applicable fees, charges, charge backs, credits
and adjustments, shall be deposited and held by BICI in a common account until
such time as the amount determined to be due Customer is paid to Customer.  BICI
will maintain an accounting of the balance owing or to be owing by BICI to
Customer of such amounts deposited and held by BICI.

SECTION 7.  CUSTOMER'S OBLIGATIONS.

The Customer agrees as follows:
      
      (a)   COOPERATION BY CUSTOMER.  Customer agrees to cooperate with BICI to
the fullest extent possible and to the best of Customer's ability to facilitate
the provisioning of services described in Section 3 herein.  Such cooperation
shall include, but not be limited to, the following:

            (i)   Supplying BICI with Customer's identification codes, any and
      all certifications of regulatory authority necessary for Customer to offer
      its services, and any other information and documents necessary or helpful
      to BICI; and

            (ii)  Supplying BICI with all technical information and assistance
      with testing that may be necessary or helpful to BICI in providing its
      services herein.

      (b)   APPLICABLE APPROVALS AND COMPLIANCE WITH LAW.  Customer shall
obtain and keep current all applicable federal, state and local licenses,
certifications and approvals and shall fully comply with all other applicable
federal, state and local regulations, laws, rules and Tariffs.  Customer agrees
that BICI shall assume and will assume no responsibility for such compliance
whatsoever.  Customer acknowledges and understands that certain LEC billing
systems contain edits and screens that "block" Customer's EMI Billing Records
from being billed to End Users until BICI can demonstrate to such LECs that
Customer has proper authority for providing its services to the End User.
Customer further acknowledges and understands that it may take as long as sixty
(60) days after notification to the LECs of such authority before the LECs will
begin billing Customer's EMI Billing Records.  Therefore, BICI will not be
responsible for billing Customer's EMI Billing Records for services provided
prior to the LECs removing their regulatory edits and screens from their billing
systems.

      (c)   VALIDATION.  Customer shall validate all collect, third party and
calling card billed MTS calls using the LECs' LIDBs (line information data
bases) or some other alternative validation method that is acceptable to the
LECs and to BICI.
      
      (d)   COMPLETED CALLS.  Customer acknowledges and agrees that where
required, Customer shall be in compliance with the FCC's order to determine call
connection using hardware or software "answer detection."  Customer further
agrees that it will submit to BICI only those EMI Billing Records for calls that
represent valid, completed calls as defined in Exhibit D attached hereto.

      (e)   AGED EMI BILLING RECORDS.  Customer shall not submit EMI Billing
Records to BICI that are more than ninety (90) days old or that exceed the "age
of toll" acceptable by the LECs, whichever is less.


                                        8 
<PAGE>



      (f)   MINIMUM TRANSMISSION VOLUMES.  Customer shall not submit to BICI
fewer than five thousand (5,000) EMI Billing Records per "library code" in any
transmission of its EMI Billing Records.  The minimum BICI Processing Fee, as 
set forth in Exhibit C attached hereto, shall apply if the minimum volume per
transmission is not met.

      (g)   OBJECTIONABLE CONTENT.  Customer agrees, as a condition of BICI's
performance under this Agreement, that BICI will not provide billing and
information management services which BICI deems harmful, damaging or against
public policy, including, but not limited to:

            (i)   Services which explicitly or implicitly refer to sexual
      conduct;

            (ii)  Services which contain indecent, obscene or profane language;

            (iii) Services which allude to bigotry, racism, sexism or other
      forms of discrimination;

            (iv)  Services which through advertising, content or delivery are
      deceptive, or that may take unfair advantage of minors or the general
      public;

            (v)   Services which are publicly accessible, multi-party
      connections commonly known as "gab" or "chat" services;

            (vi)  Services which are prohibited by Federal, state, or local laws
      or Tariffs; or

            (vii) Services which individual LECs exclude from the "types" of
      services or products for which their policies permit them to bill and
      collect.

      (h)   NO OTHER BILLING ARRANGEMENT:  Customer warrants that the EMI
Billing Records submitted and to be submitted by Customer to BICI pursuant to
this Agreement are NOT and will NOT be subject to any other valid or
existing billing and collection agreement, have NOT been billed previously and
will NOT be billed by another party following their submission by Customer to
BICI.

SECTION 8.  PROTECTION OF CONFIDENTIAL INFORMATION.

As used herein, "Confidential Information" shall mean (a) proprietary
information, (b) information marked or designated as confidential, (c)
information otherwise disclosed in a manner consistent with its confidential
nature, (d) information of one party, whether or not in written form and whether
or not designated as confidential, that is known or should reasonably be known
by the other party as being treated as confidential, and (e) information
submitted by one party to the second party where the second party knows or
reasonably should know that the first party is obligated to keep the information
confidential.  The parties hereto expressly recognize and acknowledge that, as
result of the provision of services pursuant to this Agreement, Confidential
Information which may be proprietary to each party must or may be disclosed to
the other.  Each party hereby agrees that it will make no disclosure of
Confidential Information provided under this Agreement without the prior written
consent of the other party.  Additionally, each party shall restrict disclosure
of said information to its own employees, agents or independent contractors to
whom disclosure is necessary and who have agreed to be bound by the obligations
of confidentiality hereunder.  Such employees, agents or independent contractors
shall use reasonable care, but not less care than they use with respect to their
own information of like character, to prevent disclosure of any Confidential
Information.  Nothing contained in this Agreement shall be considered as
granting or conferring rights by license or otherwise in any Confidential
Information disclosed.


                                        9 
<PAGE>



SECTION 9.  TAXES.
      
      (a)   CALCULATION OF TELECOMMUNICATIONS TAXES:  BICI will be responsible
for calculating or will use its best efforts to cause the LECs to calculate the
following taxes applicable to each MTS call and allow them to be passed through
to the End User, such taxes being referred to herein collectively as "Taxes":
Federal excise tax, any state and local sales taxes or tax-like charges, or any
Foreign Intrastate Taxes or foreign tax-like charges.  Notwithstanding the
foregoing, Customer acknowledges and agrees it is responsible for compliance
with all taxing requirements; therefore, Customer shall promptly notify BICI of
any tax or tax-like surcharges and the associated rates that apply to Customer's
MTS calls in any specific jurisdiction.

      (b)   BILLING AND COLLECTION OF TAXES:  BICI will, for the benefit of and
on behalf of Customer, use its best efforts to cause the LECs to bill End Users
for all Taxes.  Customer acknowledges and agrees that BICI is acting merely as
Customer's agent with respect to arranging for the billing and collection of
Taxes, and in no event shall BICI be entitled to retain or receive from 
Customer, or from any End User, any statutory fee or share of Taxes to which
the person collecting the same may be entitled under applicable law.

      (c)   TAX EXEMPT STATUS FOR END USERS:  BICI will have the authority, on
behalf of Customer, to authorize the LECs to calculate Taxes in the same manner
as the LECs calculate Taxes for their End Users and to authorize the LECs to
establish the tax exempt status of End Users in the same manner as the LECs
establish such status for their End Users.  If Customer's MTS calls are exempt
from federal, state and local Taxes or tax-like charges, Customer shall so
indicate on each EMI Billing Record submitted to BICI.

      (d)   FILING AND PAYMENT OF TAXES:  Based upon the information
calculated by BICI and/or received from the LECs with respect to Taxes assessed,
billed and collected by the LECs, BICI will, on behalf of Customer, prepare and
file in a timely manner with the applicable taxing authorities all returns
covering Taxes, and will, on behalf of Customer, but only to the extent of
amounts otherwise owing from BICI to Customer, pay in full and promptly remit to
such taxing authorities all Taxes owed thereto.  Upon written request, BICI will
provide to Customer copies of any and all tax returns and other applicable
information relating to the payment of Taxes by BICI within thirty (30) days
after being filed and paid by BICI.

      (e)   HOLD HARMLESS:  Customer shall indemnify and hold BICI and its
employees, agents and representatives free and harmless from and against any
Claim (including, without limitation, reasonable attorneys' fees and court
costs) relating to or arising out of any Taxes, penalties, interest, additions
to tax, surcharge or other amounts to which BICI may be subject or incur,
relating to or arising out of (i) BICI's reliance upon any calculations,
determinations or other directives, or lack thereof, given by Customer to BICI
with respect to the calculation, assessment, billing and/or collection of any
Taxes contemplated by this Agreement; or (ii) a determination by the Internal
Revenue Service or any other taxing authority that any amount paid by BICI
pursuant to paragraph 9.(d) above with respect to Taxes was insufficient, except
in the event such insufficiency was the result of gross negligence on the part
of BICI; provided, however, that Customer shall not be required to indemnify 
BICI or the employees, agents and


                                        10 
<PAGE>



representatives thereof for any loss, damage, Claim, cause of action or other
liability to the extent, but only to the extent, caused by the gross negligence
or willful misconduct of BICI.

      (f)   BILLED TAXES:  Customer shall be responsible for the payment of
any additional Taxes or tax-like charges assessed against BICI based on the
revenues collected by BICI from Customer's Valid EMI Billing Records, "Billed
Taxes" under this Agreement, excluding Federal and state income Taxes.

SECTION 10.  FORCE MAJEURE.

BICI shall not be held liable for any delay or failure in performance of any 
part of this Agreement or Exhibits attached hereto from any cause beyond its 
control and without its fault or negligence, such as acts of God, acts of 
civil or military authority, government regulations, embargoes, epidemics, 
war, terrorist acts, riots, insurrections, fires, explosions, earthquakes, 
nuclear accidents, floods, strikes, power blackouts, volcanic action, other 
major environmental disturbances, unusually severe weather conditions, 
inability to secure products or services of other persons or transportation 
facilities, or acts or omissions of transportation common carriers.

SECTION 11.  LIMITATION OF LIABILITY.

      (a)   BICI will use its best efforts at all times to provide prompt and 
efficient service; however, BICI makes no warranties or representations 
regarding the services except as specifically stated in this paragraph 11.(a).
BICI will use due care in processing all work submitted to it by Customer and 
agrees that it will, at its expense, correct any errors which are due solely 
to malfunction of BICI's computers, operating systems or programs or errors 
by BICI's employees or agents.  Correction shall be limited to reprocessing 
Customer's EMI Billing Records.  BICI will not be responsible in any manner 
for failures of, or errors in, proprietary systems and programs other than 
those of BICI, nor shall BICI be liable for errors or failures of Customer's 
software or operational systems. THIS WARRANTY IS EXCLUSIVE AND IS IN LIEU OF 
ALL OTHER WARRANTIES, AND CUSTOMER HEREBY WAIVES ALL OTHER WARRANTIES, 
EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY 
OF MERCHANTABILITY OR FITNESS FOR USE FOR A PARTICULAR PURPOSE.  Should there 
be any failure in performance or errors or omissions by BICI with respect to 
the information being processed and being submitted to the LECs for billing 
and collection, BICI's liability shall be limited to using its best efforts 
to correct such failure.  In no event, except as specifically set forth herein,
shall BICI be liable to Customer or any third parties (including Customer's 
customers) for any Claim even if BICI has been advised of the possibility of
such Claim.

      (b)   Due to the nature of the services being performed by BICI, Customer
agrees that in no event will BICI be liable for any Claim caused by BICI's
performance or failure to perform hereunder which is not reported by Customer in
writing to BICI within thirty (30) days of such performance or failure to
perform.

      (c)   Customer shall indemnify and save harmless BICI from and against any
Claim asserted against BICI by third parties and arising out of Customer's use
of the services provided


                                        11 
<PAGE>



under this Agreement, unless such Claim arises out of the willful misconduct or
gross negligence of BICI.

      (d)   Liability of BICI in any and all categories and for any and all
Claims arising out of this Agreement or out of any act or omission relating
thereto shall, in the aggregate, not exceed one (1) month's average of BICI's
Processing Fees to Customer over the twelve (12) months preceding such date in
which the damage or injury is alleged to have occurred, but if this Agreement
has not been in effect for twelve (12) months preceding such date, then over
such fewer number of preceding months that this Agreement has been in effect.

SECTION 12.  TERM OF AGREEMENT.

The initial term of this Agreement shall begin on the date on page 1 of this
Agreement or the date Customer begins submitting its EMI Billing Records to 
BICI, whichever is later, and continue in full force and effect for a minimum
period of one (1) year from such date unless terminated in accordance with 
paragraph 14.(b)(i) and shall automatically renew for successive periods of one
(1) year unless terminated by written notice from either party at least sixty
(60) days prior to the scheduled expiration date.

Notwithstanding anything to the contrary contained herein, if Customer is
currently billing more than twenty-five thousand (25,000) EMI Billing Records
per month, Customer may elect an initial term for this Agreement of two (2) or
three (3) years.  Should Customer elect to extend the initial term of this
Agreement, Customer shall pay BICI a minimum Processing Fee, as described in
Exhibit C attached hereto, each month for the entire term of this Agreement.  In
consideration for such, BICI will charge Customer a reduced billing services fee
for the term selected which coincides with the BICI fee schedule as presented in
Exhibit C, attached hereto.

SECTION 13.  EXPIRATION OR TERMINATION.

      (a)   PAYMENT UPON EXPIRATION OR TERMINATION:  Upon the expiration or
termination of this Agreement for any reason, Customer agrees to satisfy, when
or before due, any and all of its obligations arising under this Agreement.

      (b)   DEPOSIT FOR CHARGES:  In addition, Customer acknowledges and 
understands that certain LEC charges for Uncollectible Amounts, Bad Debt 
true-ups and Post-Billing Adjustments and Credits which are not determined by 
the LECs or provided to BICI for a period of up to eighteen (18) months after 
the final processing of Customer's EMI Billing Records by BICI on behalf of 
Customer. Customer further acknowledges and agrees that payment of these 
amounts shall be its sole responsibility.  To ensure such payments, Customer 
shall, at the expiration or termination of this Agreement for any reason, 
deposit with BICI an amount equal to two and one-half percent (2.5%) of the 
face amount of Customer's gross billings for the prior twelve (12) months, or 
such other amount as is estimated by BICI, based on Customer's prior history, 
necessary to satisfy such charges.  Such deposited amount shall be used by 
BICI to pay Uncollectible Amounts, Bad Debt true-ups, Post-Billing Adjustments
and Credits and other charges incurred on behalf of Customer for billing and 
collecting Customer's EMI Billing Records submitted by Customer to BICI during
the term of this Agreement. Each quarter BICI will re-examine the amount of 
funds deposited and make such adjustments as BICI estimates may

                                        12 
<PAGE>



be necessary to satisfy the aforementioned charges.  BICI will provide Customer
with proper documentation to substantiate charges attributable to Customer on
the same and consistent method as BICI determines such charges for all of its
customers.  At the end of eighteen (18) months from the expiration or
termination date, BICI will return all unused amounts to Customer.

      (c)   REMAINING LIABILITY:  Notwithstanding the foregoing, the deposit 
of such amounts does not relieve or waive Customer's responsibility and 
obligation to pay its obligations to BICI including, without limitations, any 
and all fees, charges, charge backs, credits and adjustments associated with 
billing and collecting its EMI Billing Records.  In the event such associated 
fees, charges, charge backs, credits and adjustments exceed the amount of the 
deposit described in paragraph 13.(b), Customer shall remit to BICI such 
additional amounts as are required to satisfy Customer's obligations under 
this Agreement to BICI within ten (10) Business Days of notification by BICI 
of any such amounts due.

      (d)   SAVINGS CLAUSE:  Except as otherwise provided herein, expiration
or termination of this Agreement under this Section 13 shall terminate all
further rights and obligations of the parties hereunder, provided that:
            (i)   Neither BICI nor Customer shall be relieved of its respective
      obligations to pay any sums of money due or to become due or payable or
      accrued under this Agreement;
            (ii)  If such expiration or termination is a result of a default
      hereunder or a breach hereof by a party hereto, the other party shall be
      entitled to pursue any and all rights and remedies it has to redress such
      default or breach in law or equity, subject to Sections 11, 14 and 24
      hereof; and
            (iii) The provisions of Sections 8 and 9 hereof, except paragraph
      9.(b), shall survive the expiration or termination of this Agreement.
      
      (e)   EARLY TERMINATION OF EXTENDED TERM AGREEMENT:  If Customer elects
to extend the initial term of this Agreement and should Customer terminate or
breach this Agreement before the expiration of the full initial term elected by
Customer upon execution hereof, BICI will recalculate and Customer shall pay to
BICI a processing fee for all EMI Billing Records processed under this Agreement
based on the current processing fee schedule at the one (1) year rate, attached
hereto as Exhibit C, plus ten percent (10%) for each EMI Billing Record
processed under this Agreement, at Customer's monthly volume levels.

SECTION 14.  DEFAULT AND REMEDIES.

      (a)   DEFAULT:  Either Party shall be in default hereunder if it:
            (i)   Fails to make any payment specified hereunder when or before

      notice;
            (ii)  Breaches any other material covenant or undertaking contained

      three (3) Business Days, resorts to any insolvency law, declares that it

      upon, all or any material part of the property of such party.
      
      (b)   REMEDIES:  Time is of the essence of this Agreement.  In the event

      provisions of paragraph 13.(d), by giving written notice thereof to the

      under applicable law; and
            (vi)  All rights and remedies shall be cumulative and can be

consent to any default under this Agreement, shall be effective unless the same
shall be in writing and signed by or on behalf of the party against whom such
modification, amendment, waiver or consent is claimed.  In addition, no course
of dealing or failure of any party to strictly enforce any term, right or

parties and supersedes all prior or contemporaneous agreements, and oral or

shall be an original; but such counterparts shall together constitute but one

The headings in this Agreement are for convenience only and shall not be

It is the intent of the parties hereto that Customer shall be considered by

for the same or lesser BICI Processing Fee, than any other similarly situated 
customer of BICI under this Agreement.  BICI will promptly reduce Customer's 
monthly BICI Processing Fee and minimum revenue guarantees if it should grant 
a lower rate per call or provide a greater number of out-cleared messages for 
the same or lesser BICI Processing Fee to any customer of BICI under this 
Agreement, similarly situated to Customer.  Regardless of the mechanics of 
the aforementioned, it is the intent of this clause and the principle 
hereunder that Customer be treated as well as or better than the most

Any controversy, dispute or Claim arising out of or in connection with this

Association. In the event of any procedural matter not covered by the 
aforesaid rules, the procedural law of the State of Texas shall govern.  The 
arbitration tribunal shall consist of three arbitrators.  The party 
initiating arbitration shall nominate one arbitrator in the request for 
arbitration and the other party shall nominate a second in the answer thereto 
within 15 days of receipt of the request.  The two arbitrators so named will 
then jointly appoint the third arbitrator.  If the answering party fails to 
nominate its arbitrator within the fifteen day period, or if the arbitrators 
named by the parties fail to agree on the third arbitrator within thirty 
days, the Office of the American Arbitration Association in Dallas, Texas 
shall make the necessary appointments of such arbitrator(s).  The arbitrator 
shall only have authority to award compensatory damages and shall not have 
authority to award punitive damages, other non-compensatory damages or any 
other form of relief: the parties hereby waive all rights to and claims for 
relief other than compensatory damages.  The decision or award of the 
arbitration tribunal (by a majority determination, or if there is no 
majority, then by the determination of the third arbitrator, if any) shall be 
final, and judgment upon such decision or award may be entered in the courts 
of the

State of Texas.  By execution and delivery of this Agreement, each of the

                         TELECOMMUNICATIONS AGREEMENT

      This Agreement is entered into this 10th of July, 1996, by and between
U. S. LONG DISTANCE, INC., a Texas corporation with its principal office at 9311
San Pedro, Suite 100, San Antonio, Texas 78216 ("USLD"), and BILLING INFORMATION
CONCEPTS INC., a Delaware corporation with its principal office at 9311 San
Pedro, Suite 400, San Antonio, Texas 78216 ("Customer").

                                  WITNESSETH:

      WHEREAS, USLD is in the business of providing telecommunications services;
and

      WHEREAS, Customer desires to purchase telecommunications services from
USLD:

      NOW, THEREFORE, in consideration of the mutual promises and convenants
contained herein, and for other good and valuable consideration, the parties do
hereby contract and agree as follows:

      1.    USLD agrees to furnish to Customer, and Customer agrees to purchase
from USLD, the telecommunication services as set forth in EXHIBIT "A" attached
hereto and made a part of this Agreement as if set forth verbatim herein.

      2.    This Agreement shall commence on the date on which U.S. Long 
Distance Corp. distributes the common stock, par value $.01 per share, of 
Billing Information Concepts Corp. to the holders of U.S. Long Distance 
Corp.'s common stock, par value $.01 per share (the "Commencement Date") and 
continue for a period of three (3) years. This Agreement shall be extended, 
on the same terms and conditions, for an additional period of one (1) year 
unless either party notifies the other party in writing not less than sixty 
(60) days prior to the termination date of its desire to terminate this 
Agreement.

      3.    During the term of this Agreement, USLD shall charge for the
telecommunication services, and Customer shall pay for such telecommunication
services, that amount as determined by using the rates set out in EXHIBIT "A."

      4.    USLD shall give Customer at least forty-five (45) days' notification
in the event any service rate in EXHIBIT "A" is modified.  Upon such
notification, Customer will have the right to terminate this Agreement without
penalty by providing USLD written notice within thirty (30) days of Customer's
intent to cancel service sixty (60) days from notice.

      5.    Customer hereby acknowledges that USLD's charges for the provision
of its telecommunication services will be billed on a monthly basis and that
payment for such services is due and payable fifteen (15) days from the invoice
date.  Late payments will be assessed a late charge of 1.5% per month.  Payments
not received within thirty (30) days of the invoice date will result in the
right of USLD to cancel and terminate the services provided herein, after
providing Customer with written notice, via facsimile, of such intent to
terminate service and allowing Customer ten (10) working days to cure the
deficiency.

      6.    Should Customer dispute any of the monthly charges on its monthly
invoice, it shall notify USLD of the disputed charges not later than ten (10)
days from the date of invoice.  This notice shall set forth in writing all
details concerning the disputed charges.  In the event of a dispute, Customer
shall pay the entire invoice in accordance with the payment terms set forth
therein.  After resolution of the disputed portion of the invoice, the
adjustment, if any, shall be immediately credited to Customer's account.

      7.    Should Customer claim any exemption of any sales, use or other tax,
then Customer shall provide documentation regarding such exemption to USLD.
USLD will be allowed to maintain a copy of such


<PAGE>



documentation in its offices in San Antonio, Texas.  It will be the
responsibility of Customer to make sure that its proof of exempt status remains
current.

      8.    No term or provision of this Agreement shall be deemed waived, and
no breach shall be deemed excused, unless such waiver or consent shall be in
writing and signed by the party claimed to have waived or consented.  No consent
by any party to, or waiver of, a breach or default by the other, whether
expressed or implied, shall constitute a consent to, waiver of or excuse for any
different or subsequent breach or default.

      9.    Neither USLD nor Customer shall be liable to the other for any
consequential, indirect, special or incidental damages whatsoever, including,
without limitation, any loss of revenue, goodwill, or profits or claims by third
parties or otherwise in connection with or related to any of the services
provided pursuant to this Agreement.

      10.   USLD warrants that the equipment used in providing the services to
Customer pursuant to this Agreement is suitable for the uses intended, and
Customer warrants and represents that it is fully authorized to contract for the
services under this Agreement.

           USLD MAKES NO OTHER WARRANTIES, EITHER EXPRESSED OR IMPLIED.

      11.   This Agreement authorizes USLD to start provisioning of
telecommunications services, as set forth herein, to Customer on the
Commencement Date.  This Agreement also authorizes USLD to act as Customer's
agent in placing orders with other carriers in order to provide
telecommunications services, if requested.

      12.   If the performance of the respective obligations of USLD or Customer
shall be prevented or interfered with by reason of any fire, flood, epidemic,
earthquake or any other act of God, explosion, strike or other disputes, riot or
civil disturbance, war (whether declared or undeclared) or armed conflict, any
municipal ordinance or state or federal law, governmental order or regulation or
order of any court of competent jurisdiction, or other similar forces not within
the control of USLD nor Customer, as the case may be, then Customer and/or USLD,
as the case may be, shall not be liable to the other for its failure to perform
such obligations hereunder.

      13.   If any term or provision of this Agreement shall be found to be
illegal or unenforceable, then, notwithstanding such illegality or
unenforceability, this Agreement shall remain in full force and effect and such
term or provision shall be deemed to be deleted.  In addition, this Agreement
shall be terminated upon the determination of a governmental entity having
jurisdiction over the services provided under this Agreement.

      14.   Except as otherwise provided herein, the remedies provided for in
this Agreement are in addition to any other remedies available at law or in
equity, by statute or otherwise.

      15.   Should it be necessary for either party to this Agreement to retain
the services of an attorney to enforce its rights under this Agreement, and
should any suit be necessary to enforce said rights, then the prevailing party
shall be entitled to receive reasonable attorney's fees from the other party.
      
      16.   This Agreement shall be governed by the substantive laws of the
State of Texas, without regard to conflict of law principles, with venue at San
Antonio, Texas.

      17.   This Agreement shall be binding upon and inure to the benefit of
USLD and Customer and their respective successors and assigns.  USLD retains the
right to assign all or part of this Agreement.  This Agreement may not be
assigned by Customer without the prior written consent of USLD.  USLD reserves
the right to obtain necessary credit information or require additional security
deposits from successors and assigns.

      18.   This Agreement, including the exhibits hereto and the documents and
instruments referred to therein, embodies the entire agreement and understanding
of the parties hereto in respect of the subject matter contained herein.  There
are no restrictions, promises, representations, warranties, covenants or
undertakings, other than those expressly set forth or referred to herein.  This
Agreement, and any documents and instruments contemplated hereby, supersedes all
prior agreements and understandings between the parties with respect to such
subject matter.

      19.   This Agreement may be amended, modified or supplemented only by an
instrument in writing executed by the party against which enforcement of the
amendment, modification or supplement is sought.

      20.   This Agreement may be executed in two (2) or more counterparts, each
of which shall be deemed an original.  It shall not be necessary in making proof
of this Agreement to produce or account for more than one (1) of such
counterparts.

      IN WITNESS WHEREOF, the parties have signed this Agreement as of the day
and year first above written, and the individuals signing below warrant that
they have authority to sign for and on behalf of the respective parties.
