ITEM 5. OTHER EVENTS.

    On March 21, 2000 Billing Concepts Corp. (the "Company") and its wholly
owned subsidiary, Lubbock Acquisition Corp., a Delaware corporation
("LAC"), entered into a Plan of Reorganization, Merger and Acquisition
Agreement (the "Agreement") with Operator Service Company, a Texas
corporation ("OSC"), and the stockholders of OSC.  OSC, headquartered in
Lubbock, Texas, is a privately held provider of inbound, directory assistance
and interactive voice response and customer relationship management services
to the telecommunications, car rental and consumer products industries.
Under the terms of the Agreement, the Company agreed to acquire all of the
issued and outstanding shares of capital stock of OSC ("OSC Common Stock") in
exchange for 3.846,154 shares of common stock, $.01 par value, of the Company
("Billing Common Stock").

    The acquisition was consummated on April 4, 2000, pursuant to the terms
of the Agreement, as amended on April 4, 2000, upon (1) filing of Articles of
Merger and a Certificate of Merger with the Secretary of State of the States
of Texas and Delaware, respectively, pursuant to which LAC merged with and
into OSC and became a wholly owned subsidiary of the Company, and (ii)
issuance by the Company of an aggregate of 3.846,154 shares of Billing Common
Stock to the stockholders of OSC.  This amount of consideration paid by the
Company for the OSC Common Stock was arrived at through negotiations between
the Company, OSC and the principal stockholders of OSC and was based on a
variety of factors, including, but not limited to, earnings and revenue, the
value of the goodwill and the nature of the directory assistance and
teleservices industries.  Of the 3,846,154 shares issued, 769,000 shares were
deposited in an escrow account to satisfy certain earnings obligations, and
461,573 shares were deposited in an escrow account to satisfy certain
indemnification obligations.  The acquisition will be accounted for under the
purchase method of accounting.  The Company has granted certain registration
rights for 20% of the shares issued in connection with the acquisition.
Billing Concepts, Inc., a wholly owned subsidiary of the Company, entered
into a employment agreement with a principal of OSC and Operator Service
Company, the surviving corporation in the merger and a wholly owned
subsidiary of the Company, entered into employment agreements with a
principal of OSC and eight other management and technical employees of OSC in
connection with this acquisition.

in the Surviving Corporation without further act or deed, and title to any real
estate or any interest in the real estate vested in either Seller or Purchaser
shall not revert or in any way be impaired.


        2.3 LIABILITIES. The Surviving Corporation shall be liable for all the
debts, liabilities and duties of each of Seller and Purchaser; any action or

Purchaser shall be preserved unimpaired, and all liens upon the property of each
of Seller and Purchaser shall be preserved unimpaired, on only the property
affected by the liens immediately prior to the Effective Time.

         2.4 CERTIFICATE OF INCORPORATION AND BYLAWS. The certificate of
incorporation and bylaws of Purchaser in effect immediately prior to the
Effective Time shall be the certificate of incorporation and bylaws of the
Surviving Corporation following the Merger until otherwise amended or repealed.

         2.5 DIRECTORS AND OFFICERS. The directors and officers of Purchaser
immediately prior to the Effective Time shall be the directors and officers of
the Surviving Corporation until their successors are duly elected or appointed
and qualified in the manner provided in the bylaws of the Surviving Corporation,
or as otherwise provided by law.

         2.6      CONVERSION OR CANCELLATION OF STOCK UPON MERGER

                  (a) In consideration for the Merger, the non-competition
agreements in ARTICLE 12 hereof and the non-disclosure agreement in ARTICLE
13 hereof, as of the Effective Time, by virtue of the Merger and without any
action on the part of the holders of any shares of Seller Stock, or the
holder of the shares of Purchaser Stock, (i) subject to adjustment under
SECTION 2.6(B), Seller Stock outstanding immediately before the Effective
Time shall be converted into the right to receive, subject to the provisions
of SECTION 2.8, 3,846,154 shares of BCC Stock (the "Merger Consideration");
provided, however, that 461,573 shares of the Merger Consideration (the
"Indemnity Holdback Shares") shall be pledged by the Escrow Stockholders to
secure the indemnification obligations of the Stockholders pursuant to
ARTICLE 11 hereof and 769,000 shares of the Merger Consideration (the
"Earnout Holdback Shares") shall be pledged by the Escrow Stockholders to
secure the earnout requirements pursuant to SECTION 10.10 hereof, and (ii)
each share of Purchaser Stock outstanding immediately before the Effective
Time shall be converted into one share of common stock of the Surviving
Corporation. At the Closing, BCC shall deliver to the Stockholders the
certificates representing the Merger Consideration, less the Indemnity
Holdback Shares and less the Earnout Holdback Shares.

                  (b) The number of shares constituting the Merger Consideration
will be subject to reduction at the Closing to the extent the Seller's Working
Capital is not at least $500,000 as of the Effective Time, but BCC elects to
Close, in an amount equal to the deficit between the actual Working Capital as
of the Effective Time and $500,000, valuing the shares of BCC Stock at $6.50 per
share.

         2.7 FRACTIONAL SHARES. Notwithstanding SECTION 2.6, no certificates
or scrip representing fractional shares of BCC Stock shall be issued upon the
surrender for exchange of certificates that prior to the Effective Time
represented shares of Seller Stock, no dividend or

                                       11
<PAGE>

distribution of BCC shall relate to any fractional share interest and no
fractional share interest shall entitle the owner thereof to vote or to exercise
any rights of a stockholder of BCC. In the event that any Former Seller
Stockholder shall be entitled to any fractional share interest, then any
fractional amount shall be rounded down to the nearest whole share.

         2.8 EXCHANGE PROCEDURES.

                  (a) After the Effective Time, each outstanding Certificate
shall, until duly surrendered to Purchaser as contemplated by this SECTION
2.8, be deemed to represent only the right to receive the applicable pro rata
portion of the Merger Consideration.

                  (b) After the Effective Time, there shall be no further
transfer on the records of Seller of Certificates, and each share of Seller
Stock presented or surrendered to Purchaser shall be canceled in exchange for
the applicable pro rata portion of the Merger Consideration as contemplated
by SECTION 2.6. Purchaser shall not be obligated to deliver any part of the
Merger Consideration to any holder of a Certificate until such holder
surrenders such Certificate as provided herein.

                  (c) The stock certificates representing the Indemnity
Holdback Shares shall be held in escrow by U.S. Trust Company of Texas, Inc.,
Dallas, Texas, or another escrow agent selected by BCC (the "Escrow Agent"),
which shall include any successor escrow agent appointed pursuant to the
provisions of SECTION 10.11, and the stock certificates representing the
Earnout Holdback Shares shall be held in escrow by U.S. Trust Company of
Texas, Inc., Dallas, Texas, or another escrow agent selected by BCC, which
shall include any successor escrow agent appointed pursuant to the provisions
of SECTION 10.11.

         2.9 INTERIM DIVIDENDS. No dividends or other distributions declared
after the Effective Time on BCC Stock issuable pursuant to the Merger and
payable to the Former Seller Stockholders after the Effective Time shall be paid
to the holder of any unsurrendered certificates formerly representing shares of
Seller Stock until the certificates shall be surrendered as provided herein,
provided, however, that (a) upon surrender there shall be paid to the
Stockholder in whose name the certificates representing the shares of BCC Stock
shall be issued the amount of unpaid dividends with respect to the holder's
shares of BCC Stock and (b) at the appropriate payment date, or as soon as
practicable thereafter, there shall be paid to the Stockholder the amount of
dividends declared with respect to whole shares of BCC Stock with a record date
on or after the Effective Time but before surrender and a payment date
subsequent to surrender, subject in any case to any applicable escheat laws. No
interest shall be payable with respect to the payment of dividends or other
distributions on surrender of outstanding certificates.

         2.10 FURTHER ASSURANCES. If at any time after the Effective Time the
Surviving Corporation shall consider or be advised that any further assignments
or assurances in law or otherwise are necessary or desirable to vest, perfect or
confirm, of record or otherwise, in the Surviving Corporation, all rights, title
and interests in all the Assets and all privileges, powers and franchises of
Seller and Purchaser, the Surviving Corporation and its proper officers and
directors, in the name and on behalf of Seller and Purchaser, shall execute and

or rights in the Surviving Corporation and otherwise to carry out the purpose of
this Agreement, and the proper officers and directors of the Surviving
Corporation are fully authorized in the name of Seller or otherwise to take any
and all such action.

         2.11 PAYMENTS INTO ESCROW FUNDS. When making the issuances required by
SECTION 2.8 above, and pursuant to the certificates of merger and

<PAGE>


         Seller and each Escrow Stockholder hereby, jointly and severally,
represent and warrant to the BCC Parties that the statements contained in this
Agreement made by Seller and each Escrow Stockholder are correct and complete as
of the date of this Agreement and will be correct and complete as of the Closing
Date (as though made then and as though the Closing Date were substituted for
the date of this Agreement throughout this Agreement), except as set forth in
the disclosure schedule delivered by Seller and each Escrow Stockholder to the
BCC Parties on the date hereof and initialed by the Parties, as the same may be
amended or supplemented from time to time as set forth in SECTION 8.7 hereof
(the "Disclosure Schedule"). The Disclosure Schedule will be arranged in
paragraphs corresponding to the lettered and numbered paragraphs contained in
this Agreement. Seller and each Escrow Stockholder hereby, jointly and
severally, represent and warrant to the BCC Parties as follows:

         4.1 INCORPORATION. Seller is a corporation duly organized, validly
existing and in good standing under the laws of the State of Texas, and is duly
authorized, qualified and licensed under all applicable Governmental
Requirements to carry on its business in the places and in the manner as now
conducted and to own, operate and lease the Assets it now owns, operates or
holds under lease. There has not been any claim by any other jurisdiction to the
effect that Seller is required to qualify or otherwise be authorized to do
business as a foreign corporation therein in order to carry on any of its
businesses as now conducted or to own, lease or operate the Assets. Part 4.1 of
the Disclosure Schedule sets forth a complete list of all jurisdictions in which
Seller is qualified as a foreign corporation, and Seller is in good standing in
each of such jurisdictions. There has not been any claim by any other
jurisdiction to the effect that Seller is required to qualify or otherwise be
authorized to do business as a foreign corporation therein in order to carry on
any of its businesses as now conducted or to own, lease or operate the Assets.
Complete and correct copies of the Articles of Incorporation of Seller and all
amendments thereto, certified in each case by the Secretary of State of the
State of Texas, and of the Bylaws of Seller and all amendments thereto,
certified by the Secretary of Seller, heretofore have been made available to the
BCC Parties. Neither Seller nor any Stockholder has taken any action, or failed
to take any action which action or failure will preclude or prevent Seller's
Business from being conducted in substantially the same manner in which Seller
has heretofore conducted the same. Seller has no Subsidiaries. Seller is not
engaged in any business or operations other than the Business. Except as
completely and accurately set forth on Part 4.1 of the Disclosure Schedule,
Seller is not a party to any partnership or joint venture agreement or any
agreement of any nature to acquire, directly or indirectly, any shares in the
capital of, or other equity or proprietary interest in, any person, firm or
corporation, and Seller is not a party to any agreement to acquire or lease any
other business operations.

         4.2 SHARE CAPITAL.


                                       14
<PAGE>

                  (a) The authorized capital stock of Seller consists of
15,000,000 shares of Seller Stock, of which 8,290,758 shares are outstanding
as of the date hereof and 296,342 shares, representing Rights Against Seller
Stock, are outstanding as of the date hereof. All of the outstanding Seller
Stock is held of record and beneficially by the Stockholders, in the
respective amounts set forth in Part 4.2(a) of the Disclosure Schedule, free
and clear of all Encumbrances and restrictive agreements, other than as
disclosed on Part 4.2(b) of the Disclosure Schedule. All outstanding Seller
Stock is duly authorized and issued in compliance with all federal, state and
foreign securities laws.

                  (b) Except as completely and accurately set forth on Part
4.2(b) of the Disclosure Schedule, there are outstanding on the date hereof
no rights of first refusal, preemptive rights, conversion rights, options,
convertible securities, warrants or other rights to acquire, directly or
indirectly, capital stock from Seller or from any Stockholder (collectively,
"Rights Against Seller Stock"). With the exception of 274,509 shares of
Seller Stock issued and outstanding under Seller's Stock Compensation Plan
dated effective as of January 1, 1996 as "restricted stock", all Rights
Against Seller Stock will be either extinguished or converted into Seller
Stock on or before Closing. All outstanding shares of capital stock of Seller
are duly authorized, validly issued, fully paid, and nonassessable. Except as
completely and accurately set forth in Part 4.2(b) of the Disclosure
Schedule, there are no outstanding bonds, debentures, notes or other
indebtedness or other securities of Seller having the right to vote (or
convertible into, or exchangeable for, securities having the right to vote)
on any matters on which Stockholders of Seller may vote.

                  (c) Neither Seller nor any Stockholder is a party or
subject to any agreement or understanding, and there is no agreement or
understanding between any Persons, that affects or relates to the voting or
giving of written consents with respect to any securities of Seller or the
voting by any director of Seller. Except as set forth on Parts 4.8(a)(xiv)
and 4.14(b) of the Disclosure Schedule and as reflected on the Referenced
Balance Sheet, neither any Stockholder nor any Affiliate thereof is indebted
to Seller. Seller is not indebted to any Stockholder or any Affiliate thereof
and Seller is not under any contractual or other obligation to register any
of its presently outstanding securities or any of its securities which may
hereafter be issued. Except as completely and accurately set forth in Part
4.2(c) of the Disclosure Schedule, there are no outstanding contractual
obligations, commitments, understandings or arrangements of Seller to
repurchase, redeem or otherwise acquire or make any payment in respect of any
shares of capital stock of Seller and no payments, dividends or redemption
rights in respect of any shares of capital stock of Seller are accrued, due
or payable. Except as completely and accurately set forth in Part 4.2(c) of
the Disclosure Schedule, there are no agreements or arrangements pursuant to
which Seller is or could be required to register shares of capital stock or
options under the Securities

                                       15

accounting principles applied on a consistent basis throughout the periods
indicated (except as may be indicated in the notes thereto), and present fairly,
in all material respects, the financial condition of Seller as of the dates and
for the periods indicated thereon (except for, in the case of interim period
financial information, normal year-end adjustments). The Reference Balance Sheet
reflects, as of the Balance Sheet Date, all liabilities, debts and obligations
of any nature, kind or manner of Seller, whether direct, accrued, absolute,
contingent or otherwise, and whether due, or to become due, whether or not such
items are required to be reflected on such balance sheet under generally
accepted accounting principles consistently applied. The Reference Balance Sheet

4.3(b) of the Disclosure Schedule attached hereto and made a part hereof or on
the Reference Balance Sheet, Seller does not have, and none of the Assets,
properties or Business of Seller is subject to, any liabilities or obligations
(accrued, absolute, contingent or otherwise), whether or not such liabilities
are normally shown or reflected on a balance sheet prepared in a manner
consistent with tax-basis or generally accepted accounting principles, except
for liabilities (i) incurred in the Ordinary Course of Business, or (ii) fully
covered by Seller's insurance policies, none of which have had a Material
Adverse Effect.

to the foregoing.

         4.5 COMPETING INTERESTS. Except as set forth on Part 4.5 of the
Disclosure Schedule, neither Seller nor the Escrow Stockholders, nor, to the

<PAGE>

Knowledge of Seller and each Escrow Stockholder, by any other party to a
Contract, and to the Best Knowledge of each Escrow Stockholder, none of the
Contracts will be breached by or give any other party a right of termination as
a result of the transactions contemplated by this Agreement. There are no
pending or, to the Best Knowledge of Seller and each Escrow Stockholder,
threatened disputes with respect to the Contracts. Seller is not obligated to

of Seller and each Escrow Stockholder, there are no facts or circumstances that
could reasonably be expected to result in an obligation of Seller to pay any
such liquidated damages. To the Best Knowledge of Seller and Escrow Stockholder,
there is no reason why any of the Contracts (i) will result in a loss to the
Surviving Corporation on completion by performance or (ii) cannot readily be
fulfilled or performed by the Surviving Corporation on time without undue or
unusual expenditure of money or effort. Copies of all of the documents (or in

and such copies and/or descriptions are true, substantially complete and
accurate and include all amendments, supplements or modifications thereto. All

efforts to obtain such on or before the Closing Date or within a reasonable
period of time after Closing and deliver to the BCC Parties at or prior to the
Closing.

         4.9 EFFECT OF AGREEMENT. The execution and delivery of this Agreement
by each of Seller and each Stockholder and the consummation of the transactions

Incorporation or other charter documents or bylaws of Seller; (b) result in any
violation of any Governmental Requirement applicable to any Stockholder, Seller,
the Assets or the Business; (c) conflict with, or result in any breach of, or
default or loss of any right under (or an event or circumstance that, with
notice or the lapse of time, or both, would result in a default), or the
creation of an Encumbrance pursuant to, or cause or permit the acceleration
prior to maturity or "put" right with respect to, any obligation under, any
contract, indenture, mortgage, deed of trust, lease, loan agreement or other
agreement or instrument to which Seller or any Stockholder is a party or to
which any of the Assets or Business are subject; (d) relieve any Person of any
obligation (whether contractual or otherwise) or enable any Person to accelerate
or terminate any such obligation or any right or benefit enjoyed by Seller or to
exercise any right under any agreement in respect of the Assets or the Business;

waiver or order of any Person (except as may be contemplated by the last
sentence of SECTION 4.8). Except as set forth on Part 4.9 of the Disclosure
Schedule hereto, the execution, delivery and performance of this Agreement by
Seller and each Stockholder will not result in the loss of any governmental
license, franchise or permit possessed by Seller.

Seller. Seller has made available to BCC Parties correct and complete copies of
all patents, registrations, applications, licenses and agreements and has made

respect to the Intellectual Property. Except for agreements itemized on Part
4.11(c) of the Disclosure Schedule, no agreements or arrangements are in effect

to and assumable by Purchaser as set forth herein so as to give Purchaser
exactly the same rights and/or obligations thereunder enjoyed by Seller, without
the requirement of obtaining any consent or approval, giving any prior or
subsequent notice, paying any further royalty or fee to any party thereto or to
any other third party, or performing any duty that has not already been fully
performed by Seller. Each Third-Party Software Agreement is in full force and
effect in accordance with its terms without modification or amendment and
without default by either party thereto, and without dispute by any party as to
any term or condition thereof. To the Best Knowledge of the Seller and each
Escrow Stockholder, there are no facts or documents rendering any Third-Party

Agreement. To the Best Knowledge of the Seller and each Escrow Stockholder,

within a time period to cure, pertaining to any Third-Party Software Agreement.
To the Best Knowledge of the Seller and each Escrow Stockholder, there is no
condition existing that has or will trigger a right to terminate any Third-Party
Software Agreement. To the Best Knowledge of the Seller and each Escrow
Stockholder, there is no requirement in any Third-Party Software Agreement

Software neither infringes nor is being infringed by any third party proprietary
interest, including (without limitation) any third party patent, copyright,
trademark or trade secret interest. Any usage by the Seller or in the Business
of off-the-shelf shrinkwrap and mass-market software is in compliance with the
terms thereof.

                  (e) The Intellectual Property identified in the Disclosure
Schedule constitutes all Intellectual Property used by Seller or necessary to
conduct the Business in the manner it is being conducted and as currently

Purchaser as Surviving Corporation on identical terms and conditions immediately
after the Closing. The Intellectual Property has not been licensed to any Person
or pursuant to any agreement which restricts the ability of Seller or any other
Person to use or license such.

Code, as applicable; (iv) has at all times complied with the bonding
requirements of Section 412 of ERISA; (v) has no issue pending (other than the
payment of benefits in the normal course) nor any issue resolved adversely to
Seller which may subject Seller to the payment of a penalty, interest, tax or
other amount and (vi) can be unilaterally terminated or amended on no more than

<PAGE>

                  (c) ADDITIONAL REPRESENTATIONS PERTAINING TO CERTAIN EMPLOYEE
WELFARE BENEFIT PLANS. All voluntary employee benefit associations have been
submitted to and approved as exempt from federal income tax under Section
501(c)(9) of the Code by the IRS or the applicable submission period will not
have ended prior to the Closing. No plan, arrangement or agreement with any one
or more employees will cause Seller to have liability for severance pay as a
result of the Merger. Except as listed in Part 4.25(a) of the Disclosure
Schedule, Seller does not provide employee benefits, including without
limitation, death, post-retirement medical or health coverage (whether or not
insured) or contribute to or maintain any employee benefit plan which provides
for benefit coverage following termination of employment, nor has it made any
representations, agreements, covenants or commitments to provide that coverage,
except (i) as is required by Section 4980B(f) of the Code or other applicable
statute, (ii) death benefits or retirement benefits under any employee pension
benefit plan as defined in Section 3(2) of ERISA, (iii) benefits the full cost
of which is borne by the current or former employee (or his beneficiary), or
(iv) deferred compensation benefits which have been accrued as liabilities on
the books of Seller and disclosed on its Financial Statements. All group health
plans maintained by Seller have been operated in compliance with Section
4980B(f) of the Code.

                  (d) ADDITIONAL REPRESENTATIONS PERTAINING TO CERTAIN EMPLOYEE
PENSION BENEFIT PLANS. All employee pension benefit plans as defined in Section
3(2) of ERISA which are intended to qualify under Section 401(a) of the Code
have been submitted to and approved as qualifying under Section 401(a) of the
Code by the IRS or the applicable remedial amendment period will not have ended
prior to the Closing. No facts have occurred which if known by the IRS could
cause disqualification of those plans. All employee pension benefit plans to
which Section 412 of the Code is applicable have fully complied with the funding
requirements of that Section and there is no accumulated funding deficiency as
defined in Section 302(a)(2) of ERISA (whether or not waived) in any one or more
of those plans. Seller has paid all premiums (any interest, charges and
penalties for late payment, if any applicable) due the Pension Benefit Guaranty
Corporation (the "PBGC") with respect to each employee pension benefit plan for
which premiums are required. No facts are known by Seller which will materially
increase those premiums within three years of the Closing Date. Except as set
forth on Part 4.25(d) of the Disclosure Schedule, no employee pension benefit
plan maintained by Seller has been terminated under circumstances which would
result in liability to the PBGC. There has been no "reportable event" (as
defined in Section 4043(b) of ERISA and the regulations under that Section) with
respect to any employee pension benefit plan subject to Title IV of ERISA.
Seller has not ceased operations at a facility so as to become subject to the
provisions of Section 4062(e) of ERISA, withdrawn as a substantial employer so
as to become subject to the provisions of Section 4063 of ERISA or ceased making
contributions on or before the date of the Closing to any employee pension
benefit plan subject to Section 4064(a) of ERISA to


                                       34
<PAGE>

which Seller made contributions at any time during the six years prior to the
date of Closing. Seller has not made a complete or partial withdrawal from a
multiemployer plan (as defined in Section 3(37) of ERISA) so as to incur
withdrawal liability as defined in Section 4201 of ERISA. The aggregate
withdrawal liability of Seller, computed as if a complete withdrawal by Seller
had occurred under each multiemployer pension plan as of the date hereof, would
not exceed $10,000.

                  (e) Except as disclosed in Part 4.25(e) of the Disclosure
Schedule, the transactions contemplated by this Agreement will not accelerate
the time of payment or vesting, or increase the amount, of compensation due any
director, officer or employee, consultant or former director, officer,
consultant or employee (including any beneficiary) from Seller. Except as
disclosed in Part 4.25(e) of the Disclosure Schedule, Seller is not obligated to
any employee, officer, or consultant for any deferred salary, bonus or other
compensation.

         4.26     WARRANTIES AND PRODUCT LIABILITY.

                  (a) Except for (i) warranties implied by law and (ii)
warranties disclosed on Part 4.26 of the Disclosure Schedule, Seller has not
given or made any warranties either express or implied in connection with the
sale or rental of goods or services, including, without limitation, warranties
covering the customer's consequential damages. To the Best Knowledge of Seller
and each Escrow Stockholder, and except as set forth in Part 4.26 of the
Disclosure Schedule, there is no state of facts or occurrence of any event
forming the basis of any present claim against Seller with respect to warranties
relating to products produced, manufactured, marketed, sold, transported or
distributed by Seller or services rendered or allegedly offered by or on behalf
of Seller that could reasonably be expected to materially exceed the reserves
therefor.

         10.      SPECIAL CLOSING AND POST-CLOSING COVENANTS.


                                       52
<PAGE>

         The Parties agree as follows with respect to the period following the
Closing:

         10.1 GENERAL. In case at any time after the Closing any further action
is necessary or desirable to carry out the purposes of this Agreement, each of
the Parties will take such further action (including the execution and delivery
of such further instruments and documents) as any other Party reasonably may
request, all at the sole cost and expense of the requesting Party (unless the
requesting Party is entitled to indemnification therefor under ARTICLE 11
hereof). Seller and each Stockholder acknowledges and agrees that from and after
the Closing BCC will be entitled to possession of all documents, books, records
(including Tax records), agreements and financial data of any sort relating to
the Seller.

         10.2 LITIGATION SUPPORT. In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act or transaction on or prior
to the Closing Date involving the Seller, each of the other Parties will
cooperate with him or it and his or its counsel in the contest or defense, make
available their personnel, and provide such testimony and access to their books
and records as shall be necessary in connection with the contest or defense, all
at the sole cost and expense of the contesting or defending Party (unless the
contesting or defending Party is entitled to indemnification therefor under
ARTICLE 11 hereof).

         10.3 TRANSITION. Neither Seller nor any Stockholder will take any
action that is designed or intended to have the effect of discouraging any
lessor, licensor, customer, supplier or other business associate of the Seller
from maintaining the same business relationships with the Surviving Corporation
after the Closing as it maintained with the Seller prior to the Closing. Seller
and each Stockholder will refer all customer inquiries relating to the
businesses of the Seller to BCC from and after the Closing.

         10.4 TERMINATION OF AGREEMENTS. Seller and each Escrow Stockholder
shall take all necessary efforts to ensure that the Agreements listed on Part
8.10 of the Disclosure Schedule are terminated prior to Closing.

         10.5 INTELLECTUAL PROPERTY ASSIGNMENT. Although acknowledged by all
parties as also fully enabled by the Merger memorialized by this Agreement,
Seller shall also execute a separate assignment to Purchaser of all of Seller's
right, title and interest in and to Intellectual Property, including the
Software itemized on Part 1.61 of the Disclosure Schedule. This separate
assignment shall be set forth as EXHIBIT B hereto, and recordation thereof shall
be at the sole discretion of Purchaser. In addition, any employee of the Seller,
including without limitation Michael R. Smith, will execute an


                                       53
<PAGE>

assignment to Seller and Purchaser of his right, title and interest in and to
Intellectual Property upon request of Purchaser.

         10.6 USE OF NAME OF SELLER. Immediately upon the occurrence of the
Closing, Seller and each Stockholder shall cease using the name "Operator
Service Company" and all derivations thereof. Seller and each Stockholder
covenant and agree that after the Closing they will not, directly or indirectly,
use the name "Operator Service Company" or any derivation thereof in connection
with any business enterprise.

         10.7     EMPLOYEE BENEFITS MATTER.

                  (a) Seller and BCC shall cooperate to ensure orderly transfer
of employees of the Seller to employee benefit plans of BCC.

                  (b) This SECTION 10.7 reflects the agreements of the parties
but does not create any rights or obligations except as among the parties to
this Agreement, and it is specifically agreed that no present or future employee
of the Seller will be treated as a third-party beneficiary of the provisions of
this SECTION 10.7. Nothing in this SECTION 10.7 or elsewhere in this Agreement
will preclude the Seller from terminating the employment of any employee of the
Seller, or preclude the Seller from amending or terminating in its discretion
any employee benefit plan maintained by the Seller.

         10.8 TAX-FREE REORGANIZATION. Neither Seller, any Stockholder,
Purchaser or BCC shall take any action which would disqualify the transactions
contemplated by this Agreement from treatment as a tax-free reorganization of
the Seller, to the extent that such treatment is otherwise available to such
Stockholders.

         10.9     S CORPORATION EARNINGS; 2000 INCOME TAX RETURNS.

                  (a) In order to apportion the Seller's 2000 earnings between
the Former Seller Stockholders and the Purchaser, the Actual Earnings (as
defined below) shall be allocated to the Former Seller Stockholders and the
earnings for the period beginning on the Closing Date and ending on the December
31, 2000 shall be allocated to the Purchaser. For tax and accounting purposes,
such apportionment of earnings shall be determined under the closing of the
books method consistent with Code Sections 1362(e)(3) and 1362(e)(6)(D) and the
regulations thereunder. The Former Seller Stockholders, the Seller and the
Purchaser shall take all action necessary to make the election to have the
closing of the books method apply and shall timely file such elections and
reports, including the election required under Regulation Section
1.1362-6(a)(5), to effectuate the use of the closing of the books method. On or
before the Closing Date, Former Seller Stockholders and stockholders of the
Surviving Corporation shall deliver to Purchaser, with a copy to the Stockholder
Representative, consents pursuant to Regulation 1.1362-6(a)(5) of the Code,
effective as of the Effective Time.



                                       54

<PAGE>

                  (b) No later than 60 days after the Closing Date, the
Purchaser shall deliver to the Stockholder Representative a written calculation
(the "Calculation") of the Actual Earnings for Seller to but not including the
Closing Date to be reported on its tax return (the "Actual Earnings"). In the
event the Stockholder Representative does not accept the Calculation as
accurate, the Stockholder Representative shall notify the Purchaser of the
non-acceptance of the Calculation in writing within 10 days after receipt of the
Calculation (the failure of which notice within such 10 days shall be deemed of
the acceptance of Calculation), and the Stockholder Representative and the
Purchaser shall promptly attempt to reach agreement on the correct amount of the
Calculation. In the event the Stockholder Representative and the Purchaser
cannot reach an agreement on the calculation, an independent accounting firm to
be mutually agreed upon by the Purchaser and Stockholder Representative shall
determine the correct amount of the Calculation, which determination shall be
binding on the Former Seller Stockholders and the Purchaser.

                  (c) Based upon the calculation, Purchaser shall pay to Former
Seller Stockholders, within 3 Business Days, the lesser of Actual Earnings or
$100,000, whichever is lower; provided however, any payment required to be made
by Purchaser hereunder shall not be due and payable unless and until Former
Seller Stockholders shall have executed and delivered to Purchaser a release
relating to Purchaser's obligations under this SECTION 10.9 in form and
substance reasonably acceptable to Purchaser.

                  (d) The Surviving Corporation's accountants shall be
responsible for preparing and filing the Seller's 2000 federal and state income
tax returns, and the BCC Parties shall take any and all action required in order
to file the statement that is part of the election not to apply pro rata
allocation as part of the Surviving Corporation's federal income tax return for
the period beginning on the Closing Date and ending on December 31, 2000, all in
accordance with Regulation 1.1362-6(a)(5) of the Code.

         Notwithstanding the foregoing, EBITDA as defined in the Earnout Escrow
Agreement for the entire year 2000 shall be used for purposes of calculations
under the Earnout Escrow Agreement.

         10.10 EARNOUT ESCROW. At Closing, Purchaser and Escrow Stockholders
shall deposit the Earnout Holdback Shares with the Escrow Agent pursuant to the
Earnout Escrow Agreement. The Earnout Escrow Agreement shall be executed and
delivered by the Escrow Stockholders and appropriate BCC Party at Closing. Until
such time as the Earnout Holdback Shares shall have been delivered pursuant to
the terms of the Earnout Escrow Agreement, each Escrow Stockholder covenants and
agrees not to sell, transfer, pledge, assign, hypothecate or dispose of or enter
any contract, option or pledge or understanding (written or not) with respect to
the sale, transfer, pledge, assignment, hypothecation or other disposition of
the Earnout Holdback Shares or any


                                       55
<PAGE>

dividends or distributions that may be declared or paid with respect thereof.
Nothing in this Agreement or the Earnout Escrow Agreement shall require
Purchaser or BCC to take any action after the Effective Time that it determines,
in its sole discretion, is not in the best interests of Purchaser or Surviving
Corporation or to conduct its business or the business of Surviving Corporation
contrary to its business plan or corporate governance.

         10.11 APPOINTMENT OF SUCCESSOR ESCROW AGENT. In the event the Escrow
Agent resigns and is discharged from its duties or obligations under the
Indemnity Escrow Agreement or Earnout Escrow Agreement, BCC will designate a
successor Escrow Agent prior to the expiration of the ten-day period following
the notice date of the Escrow Agent's resignation, by giving written notice to
the Indemnity Escrow Agent or Earnout Escrow Agent, as the case may be, and the
Stockholder Representative. BCC may appoint a successor Escrow Agent without the
consent of the Escrow Stockholders so long as such successor is a bank with
assets of at least $500 million, and may appoint any other successor Escrow
Agent with the consent of the Stockholder Representative, which consent shall
not be unreasonably withheld.

         10.12 HSR. To the extent required by HSR, BCC and Seller and any
requisite Stockholder shall, within 3 Business Days of the date hereof, file the
notification and report form required for the transactions contemplated
hereunder and promptly provide any supplemental information reasonably requested
in connection therewith pursuant to HSR. The Parties shall deliver to each other
copies of all filings, correspondence and orders to and from all Governmental
Authorities in connection with the transaction contemplated hereunder.

         11.      INDEMNITY.

         11.1 INDEMNIFICATION BY THE ESCROW STOCKHOLDERS. Each Escrow

Damages which may now or in the future be paid, incurred or suffered by or
asserted against such party arising out of or resulting from or relating to any
Taxes or Tax Returns of Seller for any period, or portion thereof, up to and
including the Effective Time (collectively, "Tax Losses") including without
limitation any Taxes payable as a result of the pending Texas sales Tax audit
listed on Part ___ of the Disclosure Schedule. Any claim for indemnification
under this SECTION 11.3 must be made prior to the expiration of the applicable

Any claim for indemnification under this SECTION 11.5 must be made within the
Indemnification Period.

         11.6     LIMITATION ON INDEMNIFICATION.

                  (a) The Indemnity Holdback Shares are the source from which
any and all potential claims for indemnification by the BCC Parties and any
other Indemnitee other than the Stockholders under this ARTICLE 11 shall be
satisfied and the Escrow Stockholders shall not have any liability for indemnity
claims hereunder other than the Indemnity Holdback Shares, except (i) to the
extent otherwise provided in SECTION 12.5 and ARTICLE 13 below, (ii) with
respect to claims for indemnification under SECTION 11.5 hereof, for which
Damages shall be paid in cash by the BCC Parties in an amount not to exceed the
Merger Consideration received by each Escrow Stockholder, (iii) any claim for
indemnification based on a breach of a representation, warranty or covenant
contained in SECTION 4.18 or SECTION 4.25 for which Damages shall be paid in
cash by the Escrow Stockholders (without regard to the Indemnity Holdback
Shares) in an amount not to exceed the aggregate Merger Consideration received
by Escrow Stockholders, and (iv) any claim involving the assertion of an
intentional fraud, fraud in the inducement or intentional misrepresentation or
breach, for which Damages shall be paid in cash by the Escrow Stockholders
(without regard to the Indemnity Holdback Shares) in an amount not to exceed the
aggregate Merger Consideration received by Escrow Stockholders. The
indemnification obligations of the Escrow Stockholders pursuant to SECTIONS 11.1
through 11.4 above shall be satisfied through a reduction of the Merger
Consideration effected by cancellation or other disposition by BCC of Indemnity
Holdback Shares pursuant to SECTION 11.7 of this Agreement. For purposes of any
indemnification claim under this ARTICLE 11, the Indemnity Holdback Shares shall
be valued at $6.50 per share.

                  (b) No claim for indemnification under SECTIONS 11.1, 11.2,
11.3, 11.4 and 11.5 may be brought after the expiration of the Indemnification
Period or the applicable statute of


                                       58
<PAGE>

limitations with respect to SECTION 11.3, except for claims made in accordance
with SECTION 11.9 prior to such expiration (whether or not any action, demand or
proceeding is instituted with respect to such claims prior to the expiration of
the Indemnification Period), it being understood, without limitation, that any
Damages arising after the expiration of the Indemnification Period shall be
recoverable upon notice properly given prior to the expiration of the
Indemnification Period.

         11.7 INDEMNITY HOLDBACK. The Indemnity Holdback Shares (which shall
include for purposes of this SECTION 11.7 any distributions accrued or made
thereon after the date of this Agreement), the net proceeds of any sale of
Indemnity Holdback Shares and any other securities or property which may be
issued after the date hereof in exchange for such shares in any merger or
recapitalization or similar transaction involving BCC) shall be deemed as of the
Effective Time to be deposited by the Escrow Stockholders and Purchaser with the
Escrow Agent, and certificates representing the Indemnity Holdback Shares shall
be held by the Escrow Agent. The Escrow Stockholders shall deliver to the Escrow
Agent at the Closing the Indemnity Escrow Agreement, appropriate stock powers
endorsed in blank and such other documentation as the Escrow Agent may
reasonably prescribe to carry out the purposes of this SECTION 11.7 So long as
any Indemnity Holdback Shares are held by the Escrow Agent hereunder, BCC shall
have, and the Escrow Stockholders by execution and/or approval of this Agreement
hereby grant, effective as of the Effective Time, a perfected, first priority
security interest in such Indemnity Holdback Shares to secure payment of amounts
payable by the Escrow Stockholders in respect of claims under this ARTICLE 11.
In connection therewith, the Escrow Stockholders shall execute and deliver such
instruments as BCC or the Escrow Agent may from time to time reasonably request
for the purpose of evidencing and perfecting such security interest.

         11.8 INDEMNITY ESCROW. At Closing, the Purchaser and Escrow
Stockholders shall deposit the Indemnity Holdback Shares with the Indemnity
Escrow Agent pursuant to the Indemnity Escrow Agreement. The Indemnity Escrow
Agreement shall be executed and delivered by the Escrow Stockholders and the
appropriate BCC Parties at Closing. Until such time as the Indemnity Holdback
Shares shall have been delivered to the Escrow Stockholders pursuant to the
terms of the Indemnity Escrow Agreement, each Escrow Stockholder covenants and
agrees with the BCC Parties that no Escrow Stockholder will sell, transfer,
pledge, assign, hypothecate or otherwise dispose of, or enter into any contract,
option or other pledge agreement or understanding (either written or oral) with
respect to the sale, transfer, pledge, assignment, hypothecation or other
disposition of any Indemnity Holdback Shares or any dividends or distributions
that may be declared or paid in respect thereof.

         11.9 PROCEDURE. All claims for indemnification or payment under this
ARTICLE 11 shall be asserted and resolved as follows:

                  (a) An Indemnitee shall promptly give the Indemnitor notice of
any matter which an Indemnitee has determined has given or could give rise to a
right of indemnification under this Agreement stating the amount of the Loss, if
known, and method of computation thereof, all with


                                       59
<PAGE>

reasonable particularity, and stating with particularity the nature of such
matter. Subject to SECTION 11.6(b) hereof, failure to provide such notice shall
not affect the right of the Indemnitee to indemnification except to the extent
such failure shall have resulted in liability to the Indemnitor that could have
been actually avoided had such notice been provided within such required time
period.

                  (b) The obligations and liabilities of an Indemnitor under
this ARTICLE 11 with respect to Losses arising from claims of any third party
that are subject to the indemnification provided for in this ARTICLE 11
("Third-Party Claims") shall be governed by and contingent upon the following
additional terms and conditions: if an Indemnitee shall receive notice of any
Third-Party Claim, the Indemnitee shall give the Indemnitor prompt notice of
such Third-Party Claim and the Indemnitor may, at its option, assume and control
the defense of such Third-Party Claim at the Indemnitor's expense and through
counsel of the Indemnitor's choice reasonably acceptable to Indemnitee. Subject
to the condition that notice be delivered prior to the expiration of one year
after the Effective Time, failure to provide such notice shall not affect the
right of the Indemnitee to indemnification except to the extent such failure
shall have resulted in liability to the Indemnitor that could have been actually
avoided had such notice been provided within such required time period. In the
event the Indemnitor assumes the defense against any such Third-Party Claim as
provided above, the Indemnitee shall have the right to participate at its own
expense in the defense of such asserted liability, shall cooperate with the
Indemnitor in such defense and will attempt to make available on a reasonable
basis to the Indemnitor all witnesses, pertinent records, materials and
information in its possession or under its control relating thereto as is
reasonably required by the Indemnitor. In the event the Indemnitor does not
elect to conduct the defense against any such Third-Party Claim, the Indemnitor
shall cooperate with the Indemnitee (and be entitled to participate) in such
defense and attempt to make available to it on a reasonable basis all such
witnesses, records, materials and information in its possession or under its
control relating thereto as is reasonably required by the Indemnitee. The
Indemnitor understands that if such Third-Party Claim results in an obligation
to indemnify hereunder, Damages shall include all reasonable costs and expenses
of such defense. No Third-Party Claim may be settled by Indemnitor without the
written consent of the Indemnitee. So long as the Indemnitor is vigorously
contesting any such Third-Party Claim in good faith, the Indemnitee shall not
pay or settle such claim without the Indemnitor's consent, which consent shall
not be unreasonably withheld. Written notice of any proposed settlement of any
such claim and the material terms thereof shall be delivered by Indemnitor to
Indemnitee at least ten Business Days prior to any settlement of any such claim.

                  (c) If a claim for indemnity is provided pursuant to this
ARTICLE 11 by an Indemnitee and the Indemnitor does not pay such claim or object
to such claim within 15 Business Days after notice is received by the
Indemnitor, such claim shall be deemed agreed to by the Indemnitor. If the
Indemnitor shall object to such claim, a written notice of such objection
setting forth in reasonable detail the basis for such objection shall be
provided to the Indemnitee and such dispute shall be resolved in accordance with
SECTION 18.11 hereof. In addition, if the claim shall have been determined to
have been a valid claim, Damages shall include interest at the prime rate as
quoted from time to time by Frost National Bank (San Antonio), N.A. (the "Prime
Rate") from the date the claim is first made until fully paid.


                                       60
<PAGE>

         11.10 PAYMENT. Payment of any amounts due pursuant to this ARTICLE 11
shall be made within three Business Days after resolution of the claim.

         11.11 ADJUSTMENT OF LIABILITY. The amount which an Indemnitee shall be
entitled to receive from an Indemnitor with respect to a Loss under this ARTICLE
11 shall be net of any insurance recovery by the Indemnitee on account of such
Loss. Any tax benefit actually realized by an Indemnitee on account of a Loss
that is fully indemnified by an Indemnitor shall be paid to the Indemnitor when
and if such benefit is actually recognized and then only to the extent such
benefit is attributable to the indemnified portion of the Loss. The benefit
actually recognized shall be based on the Federal Tax Returns of the Indemnitee
and any benefit shall not be considered actually recognized unless and until the
Tax Return reflecting such benefit is filed. To the extent such benefit is
disallowed or reduced in connection with any audit, the Indemnitor shall
promptly refund the amount of the benefit so disallowed or reduced.

         11.12 FAILURE TO PAY INDEMNIFICATION. If Indemnitor fails or refuses to
pay any amount due under this ARTICLE 11, the Indemnitee shall proceed in
accordance with the arbitration provisions of SECTION 18.11 hereof; provided,
however, that in the case of indemnification for a Third-Party Claim, such
matter need not be resolved by arbitration until the underlying Third-Party
Claim is finally resolved.

         11.13 COOPERATION. The Indemnitor and the Indemnitee shall cooperate
with each other with regard to any indemnification obligation under this ARTICLE
11 and each shall attempt to make available to the other on a reasonable basis
all personnel records, materials and information in its possession or under its
control as is reasonably requested by the other.

         11.14 INDEMNIFICATION IF NEGLIGENCE OF INDEMNITEE. THE INDEMNIFICATION
PROVIDED IN THIS ARTICLE 11 SHALL BE APPLICABLE WHETHER OR NOT THE SOLE OR
CONCURRENT NEGLIGENCE OR GROSS NEGLIGENCE OF THE PARTY SEEKING INDEMNIFICATION,
OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED ON THE PARTY SEEKING
INDEMNIFICATION, OR THE SOLE OR CONCURRENT LIABILITY IMPOSED VICARIOUSLY ON THE
PARTY SEEKING INDEMNIFICATION, IS ALLEGED OR PROVEN.

         12. NON-COMPETITION AGREEMENT.

         12.1 NON-COMPETITION. In consideration of the benefits of this
Agreement to each Stockholder and as a material inducement to the BCC Parties to
enter into this Agreement and pay to the Stockholders at Closing the Merger
Consideration, each Escrow Stockholder hereby covenants and agrees that,
commencing on the Closing Date and ending (a) one year from the termination of
employment under the Employment Agreement to be executed at Closing, as to James
Kirk Smith, or (b) two years from termination of employment under the Employment
Agreement to be executed at Closing, as to Michael R. Smith, such Escrow
Stockholder shall not, and such Escrow Stockholder shall cause his Associates,
Affiliates and representatives not to, directly or indirectly, as proprietor,
partner, stockholder, director, executive, officer, employee, consultant, joint
venturer,


                                       61

 investor or in any other capacity, engage in, or own, manage, operate
or control, or participate in the ownership, management, operation or control,
of any entity which engages in any business activity which is similar to or in
competition with the business of Surviving Corporation, BCC Parties and their
Affiliates; provided, however, the foregoing shall not prohibit (a) an Escrow
Stockholder, his Associates, Affiliates and representatives from purchasing and
holding as an investment not more than 3% of any class of publicly traded
securities of any entity which conducts a business in competition with the
business of the BCC Parties, so long as such Escrow Stockholder, his Associates,
Affiliates and representatives do not participate in any way in the management,
operation or control of such entity, or (b) Michael R. Smith from accepting
employment during the period of non-competition as long as he obtains the
written permission and authorization of the Board of Directors of BCC.

         12.2 JUDICIAL REFORMATION. Each Escrow Stockholder acknowledges that,
given the nature of the BCC Parties' business, the covenants contained in
SECTION 12.1 establish reasonable limitations as to time, geographic area and
scope of activity to be restrained and do not impose a greater restraint than is
reasonably necessary to protect and preserve the goodwill of the BCC Parties'
business and to protect their legitimate business interests. If, however,
SECTION 12.1 is determined by any court of competent jurisdiction to be
unenforceable by reason of its extending for too long a period of time or over
too large a geographic area or by reason of it being too extensive in any other
respect or for any other reason, it will be interpreted to extend only over the
longest period of time for which it may be enforceable and/or over the largest
geographic area as to which it may be enforceable and/or to the maximum extent
in all other aspects as to which it may be enforceable, all as determined by
such court.

         12.3 CUSTOMER LISTS; NON-SOLICITATION. Each Escrow Stockholder further
covenants and agrees that he shall not, and such Escrow Stockholder will cause
his Associates, Affiliates and representatives not to, directly or indirectly,
(a) use or make known to any person or entity the names or addresses of any
clients or customers of Seller or the BCC Parties or any other information
pertaining to them, provided, however, such limitation shall not apply to any
information which (i) is then generally known to the public, (ii) become or
becomes generally known to the public through no fault of such Escrow
Stockholder, his Associates, Affiliates and representatives, and (iii) is
disclosed in accordance with an order of a court of competent jurisdiction or
applicable law, (b) call on, solicit, take away or attempt to call on, solicit
or take away any clients or customers of Seller or the BCC Parties, nor (c)
solicit for employment, recruit, hire or attempt to recruit or hire any
employees of Seller or the BCC Parties.

         12.4 COVENANTS INDEPENDENT The covenants of each Escrow Stockholder
contained in SECTIONS 12.1, 12.2 and 12.3 of this Agreement will be construed as
independent of any other provision in this Agreement, and the existence of any
claim or cause of action by any Escrow Stockholder against the BCC Parties will
not constitute a defense to the enforcement by the BCC Parties of said
provisions. Each Escrow Stockholder understands that the provisions contained in
SECTIONS 12.1, 12.2 and 12.3 are essential elements of the transactions
contemplated by this Agreement and, but for the agreement of the Escrow
Stockholders to be bound by the provisions of SECTIONS 12.1, 12.2 and 12.3, the
BCC Parties would not have agreed to enter into this Agreement



                                       62
<PAGE>

and the transactions contemplated herein. Each Escrow Stockholder has been
advised to consult with, and represents that he has consulted with, counsel in
order to be informed in all respects concerning the reasonableness and propriety
of SECTIONS 12.1, 12.2 and 12.3 with specific regard to the nature of the
business conducted by Seller and the BCC Parties and each Escrow Stockholder
acknowledges that SECTIONS 12.1, 12.2 and 12.3 are reasonable in all respects.

         12.5 REMEDIES Each Escrow Stockholder acknowledges that in the event of
a breach or a threatened breach by an Escrow Stockholder of any of the
provisions contained in SECTIONS 12.1, 12.2 or 12.3 of this Agreement, the BCC
Parties will suffer irreparable damage or injury not fully compensable by money
damages, or the exact amount of which may be impossible to ascertain, and
therefore, the BCC Parties will not have an adequate remedy at law. Accordingly,
the BCC Parties shall be entitled to such injunctive relief or other equitable
relief, without the necessity of posting bond therefor, from any court of
competent jurisdiction as may be necessary or appropriate to prevent or curtail
any such actual or threatened breach. The foregoing shall be in addition to and
without prejudice to any other rights that the BCC Parties may have under this
Agreement, at law or in equity, including, without limitation, the right to sue
for and recover money damages.

         13. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION. Each Stockholder
recognizes and acknowledges that he has and will have access to certain
confidential information of Seller that is included in the Assets (including,
but not limited to, lists of customers, software designs, system specifications,
trade secrets, Software source code, and costs and financial information) that
after the consummation of the transactions contemplated hereby will be valuable,
special and unique property of Purchaser. Each Stockholder agrees that he will,
and will cause his Associates, Affiliates and representatives, to keep
confidential and not disclose to any other Person or use for his own benefit or
for the benefit of any other Person, and he will use his best efforts to prevent
disclosure by any other Person of, any such confidential information to any
Person for any purpose or reason whatsoever, except to authorized
representatives of Purchaser; provided, however, such limitation shall not apply
to any information which (i) is then generally known to the public; (ii) become
or becomes generally known to the public through no fault of a Stockholder, his
Associates, Affiliates and representatives, and (iii) is disclosed in accordance
with an order of a court of competent jurisdiction or applicable law. Seller or
a Stockholder may have entered into certain confidentiality agreements with
third parties regarding the possible sale of Seller or its Business. Seller
and/or such Stockholder has previously requested that all such third parties
return to Seller all confidential information provided to such parties by or on
behalf of Seller or such Stockholder or that such information be destroyed. At
the Closing, Seller shall assign all of its rights in and to any such
confidentiality agreements to Purchaser. Each Stockholder acknowledges that in
the event of a breach or threatened breach by a Stockholder of any of the
provisions contained in this ARTICLE 13, the BCC Parties will suffer irreparable
damage or injury not fully compensable by money damages, or the exact amount of
which may be impossible to ascertain, and therefore, the BCC Parties will not
have an adequate remedy at law. Accordingly, the BCC Parties shall be entitled
to such injunctive relief or other equitable relief, without the necessity of
posting bond therefor, from any court of competent jurisdiction as may be
necessary or appropriate to prevent or curtail any such actual or threatened
breach. The foregoing shall be in addition to and without prejudice to any other
rights


                                       63
<PAGE>

that the BCC Parties may have under this Agreement, at law or in equity,
including, without limitation, the right to sue for and recover money damages.

this Agreement as provided below:

                  (a) BCC and Seller may terminate this Agreement by mutual
written consent at any time prior to the Closing;

                  (b) BCC may terminate this Agreement by giving written notice
to Seller on or before the Closing Date if BCC is not satisfied with the results
of its continuing business, legal and accounting due diligence regarding the
Seller;

                  (c) BCC may terminate this Agreement by giving written notice
to Seller at any time prior to the Closing (i) in the event the Seller or any
Stockholder has breached any representation, warranty or covenant contained in
this Agreement in any material respect, BCC has notified Seller of the breach,
and the breach has continued without cure for a period of 15 days after the
notice of breach or (ii) if the Closing shall not have occurred on or before May
31, 2000, by reason of the failure of any condition precedent under SECTION 9.1
hereof (unless the failure results primarily from BCC itself breaching any
representation, warranty or covenant contained in this Agreement); and

                  (d) Seller and the Stockholders may terminate this Agreement
by giving written notice to BCC at any time prior to the Closing (i) in the
event BCC has breached any representation, warranty or covenant contained in
this Agreement in any material respect, Seller has notified BCC of the breach,
and the breach has continued without cure for a period of 15 days after the

31, 2000, by reason of the failure of any condition precedent under SECTION 9.2

Agreement).

         15.2 EFFECT OF TERMINATION. If any Party terminates this Agreement
pursuant to ARTICLE 15, all rights and obligations of the Parties hereunder

         16. GUARANTEE. Each Escrow Stockholder hereby (a) unconditionally
guarantees the prompt performance of the obligations of Seller under this
Agreement, (b) waives any requirements of notice, protest, demand or grace with
respect thereto other than those contained in this Agreement and (c) agrees that
the BCC Parties shall not be required to exhaust their remedies against any
other person or party (including, but not limited to, Seller or any Stockholder)
before enforcing the provisions of this guarantee. Each Escrow Stockholder
recognizes and acknowledges that the BCC Parties are relying on this guarantee
in entering into and consummating the transactions contemplated by this
Agreement, and that but for this guarantee the BCC Parties would not enter into
this Agreement or consummate the transactions contemplated hereby. Any liability
resulting from the foregoing guarantee shall be limited to the Indemnity
Holdback Shares.

         17.  STOCKHOLDER REPRESENTATIVE.

                  (a) In order to administer efficiently the implementation of
this Agreement, the waiver of any conditions to the obligations to consummate
the transactions or the settlement of any dispute and notices under this
Agreement or actions, settlement or notices under the Earnout Escrow Agreement
or Indemnity Escrow Agreement, Stockholders hereby appoint James Kirk Smith as
their representative ("Stockholder Representative") and authorize him to take
all action necessary in connection with implementation of the Agreement on
behalf of Stockholders, waive any condition to or obligation to consummate the
transactions, give and receive notices and take any and all action contemplated
to be taken by or on behalf of Stockholders under this Agreement, and of Escrow
Stockholders under the Earnout Escrow Agreement and the Indemnity Escrow
Agreement (collectively, "Escrow Agreements").

                  (b) In the event Stockholder Representative dies, becomes
legally incapacitated or resigns Michael R. Smith shall fill such vacancy and be
deemed Stockholder Representative for all purposes; however, no change of the
Stockholder Representative shall be effective until Purchaser is given notice of
it by the Stockholders.

                  (c) By mere execution of this Agreement, Stockholders agree
that:

                                    (i) Purchaser may rely conclusively on the
                  instructions and decisions of Stockholder Representative as to
                  any actions required or permitted to be taken by Stockholders
                  or Stockholder Representative hereunder and under the Escrow
                  Agreements and no party shall have any cause of action against
                  Purchaser for action taken by Purchaser in reliance upon
                  actions, decisions or instructions of Stockholder
                  Representative.

                                    (ii) all actions, decisions, and
                  instructions of the Stockholder Representative shall be
                  conclusive and binding on Stockholders; no Stockholder shall
                  have a cause of action against Purchaser or Surviving
                  Corporation for any action taken or omitted,



                                       66
<PAGE>

                  decision made or omitted or any instruction as given or
                  omitted by Stockholder Representative hereunder.

                                    (iii) Stockholder Representative shall be
                  deemed to fulfill any fiduciary obligation to Stockholders so
                  long as no Stockholder is adversely affected by any action or
                  failure to act by Stockholder Representative in a
                  disproportionate measure compared to any other Stockholder.

                  (d) Remedies at law for breach of this Section would be
inadequate, therefore Purchaser shall be entitled to injunctive relief, without
the necessity of proving damages in an action to enforce this Section.

                  (e) The provisions of this Section are independent and
severable to constitute an irrevocable power of attorney, coupled with an
interest and surviving death, granted by each Stockholder to the Stockholder
Representative and bind executors, heirs, successors, and legal representatives.
All reasonable fees and expenses incurred by Stockholder Representative shall be
paid by Stockholders pro rata in proportion to their percentage interest in
Seller immediately before the Effective Time. The provisions hereof shall
survive the Effective Time.

         18.  GENERAL PROVISIONS.

         18.1 GOVERNING LAW; INTERPRETATION; SECTION HEADINGS. This Agreement
shall be governed by and construed and enforced in accordance with the laws of
the State of Texas without regard to conflict-of-laws rules as applied in Texas.
The section headings contained herein are for purposes of convenience only and
shall not be deemed to constitute a part of this Agreement or to affect the
meaning or interpretation of this Agreement in any way.

         18.2 SEVERABILITY. Should any provision of this Agreement be held
unenforceable or invalid under the laws of the United States of America or the
State of Texas, or under any other applicable laws of any other jurisdiction,
then the parties hereto agree that such provision shall be deemed modified for
purposes of performance of this Agreement in such jurisdiction to the extent
necessary to render it lawful and enforceable, or if such a modification is not
possible without materially altering the intention of the parties hereto, then
such provision shall be severed herefrom for purposes of performance of this
Agreement in such jurisdiction. The validity of the remaining provisions of this
Agreement shall not be affected by any such modification or severance, except
that if any severance materially alters the intentions of the parties hereto as
expressed herein (a modification being permitted only if there is no material
alteration), then the parties hereto shall use commercially reasonable efforts
to agree to appropriate equitable amendments to this Agreement in light of such
severance, and if


                                       67
<PAGE>

no such agreement can be reached within a reasonable time, any party hereto may
initiate arbitration pursuant to the provisions of SECTION 18.11 to determine
and effect such appropriate equitable amendments.

         18.3 ENTIRE AGREEMENT. This Agreement, the Disclosure Schedule and the
documents and agreements referenced herein set forth the entire agreement and
understanding of the parties hereto with respect to the transactions
contemplated hereby and supersede all prior agreements, arrangements and
understandings related to the subject matter hereof. No representation, promise,
inducement or statement of intention has been made by any party hereto which is
not embodied or referenced in this Agreement, the Disclosure Schedule or the
documents or agreements referenced herein, and no party hereto shall be bound by
or liable for any alleged representation, promise, inducement or statement of
intention not so set forth.

         18.4 BINDING EFFECT. All the terms, provisions, covenants and
conditions of this Agreement shall be binding upon and inure to the benefit of

parties hereto shall not be assigned or delegated by any party hereto without

superseded or canceled, and subject to the authority of Stockholder
Representative under ARTICLE 17, any of the terms, provisions, representations,
warranties, covenants or conditions hereof may be waived, only by a written
instrument executed by all parties hereto, or, in the case of a waiver, by the
party waiving compliance. The failure of any party at any time or times to
require performance of any provision hereof shall in no manner affect the right
to enforce the same. No waiver by any party of any condition contained in this
Agreement, or of the breach of any term, provision, representation, warranty or
covenant contained in this Agreement, in any one or more instances, shall be
deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach of
any other term, provision, representation, warranty or covenant.

         18.7 GENDER; NUMBERS. All references in this Agreement to the

appropriate, be deemed to be singular, and VICE VERSA.

or more counterparts, each of which shall be deemed an original, but all of
which together


                                       68
<PAGE>

shall constitute one and the same instrument. This Agreement shall be binding
when one or more counterparts hereof, individually or taken together, shall bear
the signatures of the parties reflected hereon as signatories.

         18.9 TELECOPY EXECUTION AND DELIVERY. A facsimile, telecopy or other
reproduction of this Agreement may be executed by one or more parties hereto,
and an executed copy of this Agreement may be delivered by one or more parties

         18.11 ARBITRATION.

                  (a) EXCEPTION PRIOR TO EFFECTIVE TIME. The parties acknowledge
that money damages are not an adequate remedy for violations of this Agreement
and that, prior to the Effective Time, any party may, in its sole discretion,
apply to a court of competent jurisdiction for specific performance or
injunctive or such other relief as such court may deem just and proper to
enforce this Agreement or to prevent any violation hereof and, to the extent
permitted by applicable law, each party waives any objection to the imposition
of such relief.

                  (b) EXCEPTIONS TO ENFORCE ARTICLES 12 AND 13. The Parties
expressly reserve the right to petition a court directly for injunctive and
other relief to enforce a breach of the restrictive covenants and non-disclosure
provisions of ARTICLES 12 OR 13 of this Agreement and may seek in conjunction
with such relief, damages caused by breach of ARTICLES 12 OR 13 of this
Agreement.

                  (c) DISPUTES TO BE ARBITRATED. Any controversy of any nature
whatsoever, including but not limited to tort claims or contract disputes,
between the parties to this Agreement or their respective heirs, executors,
administrators, legal representatives, successors and assigns, as applicable,
arising out of or related to this Agreement after the Effective Time, including
the implementation, applicability and interpretation thereof, shall, upon the
written request of one party served upon the other, be submitted to and settled
by arbitration in accordance with the provisions of the Federal Arbitration Act,
9 U.S.C. Section 1-15, as amended. The terms of the commercial arbitration
rules of the American Arbitration Association (the "AAA") shall apply except to
the extent they conflict with the provisions of this paragraph. If the amount in


                                       69
<PAGE>

controversy in the arbitration exceeds Two Hundred and Fifty Thousand Dollars
($250,000), exclusive of interest, attorneys' fees and costs, the arbitration
shall be conducted by a panel of three independent arbitrators. Otherwise, the
arbitration shall be conducted by a single independent arbitrator. The parties
shall endeavor to select independent arbitrators by mutual agreement. If such
agreement cannot be reached within 30 calendar days after a dispute has arisen
which is to be decided by arbitration, the selection of the arbitrator(s) shall
be made in accordance with Rule 13 of the Rules as presently in effect. If three
arbitrators are selected, the arbitrators shall elect a chairperson to preside
at all meetings and hearings. If a dispute is to be resolved by a sole
arbitrator in accordance with the terms hereof, or if the dispute is to be
resolved by a panel of three arbitrators as provided hereinabove, then each such
arbitrator shall be a member of a state bar engaged in the practice of law in
the United States or a retired member of a state or the federal judiciary in the
United States. The award of the arbitrator(s) shall require a majority of the
arbitrators in the case of a panel of arbitrators, shall be based on the
evidence admitted and the substantive law of the State of Texas and shall
contain an award for each issue and counterclaim. The award shall be made 30
days following the close of the final hearing and the filing of any post hearing
briefs authorized by the arbitrator(s). The award of the arbitrator(s) shall be
final and binding on the parties hereto. Each party shall be entitled to inspect
and obtain a copy of non-privileged relevant documents in the possession or
control of the other party. All such discovery shall be in accordance with
procedures approved by the arbitrator(s). Unless otherwise provided in the
award, each party shall bear its own costs of discovery.

                  (d) DISCOVERY. Each party shall be entitled to take one
deposition. Each party shall be entitled to submit one set of interrogatories
which require no more than 30 answers. All discovery shall be expedited,
consistent with the nature and complexity of the claim or dispute and consistent
with fairness and justice. The arbitrator(s) shall have the power to compel any
party to comply with discovery requests of the other parties and to issue
binding orders relating to any discovery dispute which shall be enforceable in
the same manner as awards. The arbitrator(s) also shall have the power to impose
sanctions for abuse or frustration of the arbitration process, including without
limitation, the refusal to comply with orders of the arbitrator(s) relating to
discovery and compliance with subpoenas.

                  (e) ATTORNEYS' FEES. The arbitrator(s) shall require the
non-prevailing party to pay the prevailing party's attorneys' fees and costs
incurred in connection with the arbitration. It is further agreed that any of
the parties hereto may petition the United States District Court for the Western
District of Texas, San Antonio Division, for a judgment to be entered upon any
award entered through such arbitration proceedings. All arbitration proceedings
shall be conducted in San Antonio, Texas.

         18.12 DAMAGE TO ASSETS. If, on or before the Closing Date, the assets
or properties of the Seller are damaged or destroyed, Seller and the
Stockholders shall notify BCC of such damage or destruction. In the event of any
such damage or destruction, BCC shall have the right, in its sole discretion, to
either (i) reduce the Merger Consideration by an amount equal to the value of
the damaged or destroyed asset or assets, and complete the purchase, or (ii)
terminate this Agreement as provided by SECTION 15.1 hereof and not complete the
purchase.

         18.13 EFFECT OF DUE DILIGENCE. No investigation by or on behalf of the
BCC Parties into the business, operations, prospects, assets or condition
(financial or otherwise) of the Seller shall diminish in any way the effect of
any representations or warranties made by Seller or any Stockholder in this
Agreement or shall relieve Seller or any Stockholder of any of its or his
obligations under this Agreement.

         18.14 PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of BCC
and Seller; provided, however, that any Party may make any public disclosure it
believes in good faith is required by applicable law (in which case the
disclosing Party will use its reasonable best efforts to advise the other
Parties prior to making the disclosure).

         18.15 NO THIRD PARTY BENEFICIARIES. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

         18.16 CONSTRUCTION. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty and covenant contained herein shall have
independent significance. If any Party has breached any representation, warranty
or covenant contained herein in any respect, the fact that there exists another
representation, warranty or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the Party has not
breached shall not detract from or mitigate the fact that the Party is in breach
of the first representation, warranty or covenant.

Exhibits, Annexes and Disclosure Schedule identified in this Agreement are
incorporated herein by reference and made a part hereof.

         18.18 SPECIFIC PERFORMANCE. Each of the Parties acknowledges and agrees
that the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Parties shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter, in addition to any other remedy to which they may be
entitled, at law or in equity.

         18.19 REMEDIES CUMULATIVE. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise or beginning of
the exercise of any thereof by any party shall not preclude the simultaneous or
later exercise of any other such right, power or remedy by such party.

                            AND ACQUISITION AGREEMENT

         WHEREAS, a Plan of Reorganization, Merger and Acquisition Agreement
(the "Plan") was executed on March 21, 2000 among Billing Concepts Corp.
("BCC"), Lubbock Acquisition Corp. ("Purchaser") and Operator Service Company
("Seller") and its Stockholders.

         WHEREAS, capitalized terms not defined herein shall have the meanings
assigned in the Plan.

         WHEREAS, the Parties have determined to effectuate the Merger
contemplated under the Plan by having the Seller, rather than the Purchaser, be
the Surviving Corporation.

         WHEREAS, the Earnout Escrow is to be funded by all of the Stockholders
proportionally and not only the Escrow Stockholders.

         NOW THEREFORE, it is agreed as follows:

1.       The fifth recital of the Plan is amended to read:

         "WHEREAS, the respective boards of directors of Purchaser and Seller
         have voted to approve the merger of Purchaser with and into Seller (the
         "Merger") pursuant to the terms and subject to the conditions of this
         Agreement; and"

2 .      The last paragraph of the recitals is amended to read:

         "NOW, THEREFORE, in consideration of the mutual covenants hereinafter
         contained, the parties hereto agree that Purchaser shall be merged with
         and into Seller and that the terms and conditions of the Merger, the
         method of carrying the Merger into effect and certain other provisions
         relating thereto shall be as hereinafter set forth:"

3.        Section 1.64 of the Plan is amended to read:

         "1.64 "SURVIVING CORPORATION" shall mean the Seller, existing at and
         after the Effective Time as a result of the Merger."

4.       The first sentence of Section 2.1 of the Plan is amended to read:


<PAGE>

         "Subject to the terms and conditions of this Agreement, Purchaser shall
         be merged with and into Seller in accordance with all applicable laws,
         with Seller being the Surviving Corporation."

5.       Section 2.6 (a) is amended to read:

         "(a) In consideration for the Merger, the non-competition agreements in
         ARTICLE 12 hereof and the non-disclosure agreement in ARTICLE 13
         hereof, as of the Effective Time, by virtue of the Merger and without
         any action on the part of the holders of any shares of Seller Stock, or
         the holder of the shares of Purchaser Stock, (i) subject to adjustment
         under SECTION 2.6(B), Seller Stock outstanding immediately before the
         Effective Time shall be converted into the right to receive, subject to
         the provisions of SECTION 2.8, 3,846,154 shares of BCC Stock (the
         "Merger Consideration"); provided, however, that 461,573 shares of the
         Merger Consideration (the "Indemnity Holdback Shares") shall be pledged
         by the Escrow Stockholders to secure the indemnification obligations of
         the Stockholders pursuant to ARTICLE 11 hereof and 769,000 shares of
         the Merger Consideration (the "Earnout Holdback Shares") shall be
         pledged by the Stockholders to secure the earnout requirements pursuant
         to SECTION 10.10 hereof, and (ii) each share of Purchaser Stock
         outstanding immediately before the Effective Time shall be converted
         into one share of common stock of the Surviving Corporation. At the
         Closing, BCC shall deliver to the Stockholders the certificates
         representing the Merger Consideration, less the Indemnity Holdback
         Shares and less the Earnout Holdback Shares."

6.       Section 2.11 (a) is amended to read:

         "(a) the BCC Parties shall withhold from each Stockholder on a pro rata
         basis and Purchaser and Stockholders shall deliver to the Escrow Agent
         under the Earnout Escrow Agreement, the Earnout Holdback Shares, to be
         held and distributed by the Escrow Agent pursuant to the terms of this
         Agreement and the Earnout Escrow Agreement; and"

7.       The last sentence of Section 4.8(c) is amended to read:

         "All of the Contracts will be fully vested in Surviving Corporation as
         of the Effective Time of the Merger, without the approval or consent of
         any Person, or, if such approval or consent is required, Escrow
         Stockholders will use their best efforts to obtain such on or before
         the Closing Date or within a reasonable period of time after Closing
         and deliver such to the BCC Parties."

         any other impediment to Surviving Corporation's quiet enjoyment in the
         operation thereof (subject to minor imperfections in the Software that
         are standard in the software industry)."

9.       The first sentence of Section 4.11(d) is amended to read:

         the same rights and/or obligations thereunder enjoyed by Seller,
         without the requirement of obtaining any consent or approval, giving
         any prior or subsequent notice, paying any further royalty or fee to
         any party thereto or to any other third party, or performing any duty

         Service Company" or "OSC" or any derivation thereof in connection with

         Stockholder covenants and agrees not to sell, transfer, pledge, assign,
         hypothecate or dispose of or enter any contract, option or pledge or
         understanding (written or not) with respect to the sale, transfer,
         pledge, assignment, hypothecation or other disposition of the Earnout
         Holdback Shares or any dividends or distributions that may be declared
         or paid with respect thereof. Nothing in this Agreement or the Earnout
         Escrow Agreement shall require Surviving Corporation or BCC to take any
         action after the Effective Time that BCC determines, in its sole
         discretion, is not in the best interests of Surviving Corporation or to
         conduct its business or the business of Surviving Corporation contrary
         to the Surviving Corporation's business plan or corporate governance."

         "Surviving Corporation."

         changed to "Stockholders" with relation to the Earnout Escrow.

         "Purchaser, Surviving Corporation or BCC Parties."

19.      Except as modified above and as otherwise necessary in context to
         reflect the fact that Purchaser will be merging with and into Seller as
         the Surviving Corporation and all Stockholders will be funding the
         Earnout Escrow, all other terms and conditions of the Plan remain in
         full force and effect.
