                          NOTES TO FINANCIAL STATEMENTS
                                  JUNE 30, 1997

A.        BASIS OF PRESENTATION

          The accompanying unaudited financial statements have been prepared in
          accordance with the instructions to Form 10-Q and do not include all
          of the information and footnotes required by generally accepted
          accounting principles for complete financial statements. In the
          opinion of management, all adjustments (consisting only of normal
          occurring accruals) considered necessary for a fair presentation have
          been included.

B.        ACCOUNTING POLICIES

          NET LOSS PER SHARE

          Net loss per common share is computed by dividing the net loss by the
          weighted average common shares outstanding during each period. Common
          stock equivalents, consisting of common shares issuable upon the
          exercise of stock options (using the treasury stock method), are not
          included in the net loss per common share computation as their effect
          would be anti-dilutive.

          RECENT ACCOUNTING PRONOUNCEMENT

          In February 1997, the Financial Accounting Standards Board issued SFAS
          128, Earnings per Share. SFAS 128 will be effective for financial
          statements for periods ending after December 15,1997, including
          interim periods, and establishes standards for computing and
          presenting earnings per share. In its consolidated financial
          statements for the year ending December 31, 1997, the Company will
          make the required disclosures of basic and diluted earnings per share,
          as applicable, and provide a reconciliation of the numerator and
          denominator of its basic and diluted earnings per share computations.
          All prior period earnings per share data will be restated by the
          Company in the period of adoption of SFAS 128, which is not expected
          to have a material effect on the presentation of the Company's
          earnings (loss) per common share data.

                            BROCK INTERNATIONAL, INC.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS - THE QUARTER ENDED JUNE 30, 1997 COMPARED TO THE QUARTER
ENDED JUNE 30, 1996, AND THE SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO THE SIX
MONTHS ENDED JUNE 30, 1996.

Total revenues decreased 29.9% from $5,818,000 in the second quarter of 1996 to
$4,080,000 in the second quarter 1997. Year to date, total revenues decreased
42.6% to $7,488,000 from $13,043,000 in the same period of 1996. These decreases
were due to lower software and services revenues. Software revenues decreased
49.9% from $2,377,000 in the second quarter of 1996 to $1,191,000 in the same
period of 1997. For the first six months of 1997 software revenues decreased
65.9% to $1,910,000 from $5,600,000 in 1996.

Revenues from international license sales increased 25.7% from $806,000 in the
second quarter of 1996 to $1,013,000 in the corresponding quarter of 1997. Year
to date, revenues from international licenses decreased 54.4% from $2,804,000 in
1996 to $1,279,000 in 1997. As a percentage of total revenues, international
revenues increased to 24.8% in the second quarter of 1997 compared to 13.9% in
second quarter 1996, but year to date, decreased as a percentage of total
revenues from 21.5% in 1996 to 17.1% in 1997. During the second quarter of 1997
there were no sales to customers in any foreign country which were in excess of
10% of total revenues. The decrease in year to date international and domestic
software revenue can be attributed to a smaller sales force, 37 employees in the
second quarter of 1996 compared to 14 employees in the second quarter of 1997.
During the second quarter of 1997, the sales force began rebuilding and three
new sales employees were brought on board which management believes will begin
to contribute to generating sales revenue.

Services revenues decreased 28.7% from $1,875,000 in the second quarter of 1996
to $1,336,000 in the second quarter of 1997. Year to date, services revenues
decreased 38.3% from $4,214,000 in 1996 to $2,601,000 in 1997. The decrease in
services revenues is consistent with the year to date decrease in domestic
software license revenues. Maintenance revenues increased 5.3% from $1,310,000
in the second quarter of 1996 to $1,380,000 in the same period of 1997. For the
first six months of 1997, maintenance revenues remained fairly consistent at
$2,644,000 from $2,661,000 for the first six months of 1996. Other revenues
decreased 32.4% from $256,000 in the second quarter of 1996 to $173,000 in the
second quarter of 1997. Year to date, other revenues decreased 41.4% to $333,000
in 1997 from $568,000 in 1996 primarily due to decreases in certain reimbursable
travel charges consistent with the decline in services revenue.

During the second quarter of 1997, the Company continued to see the results of
the restructuring of operations initiated during the fourth quarter of 1996. The
results included company wide decreases of personnel and related costs totaling
approximately $1,556,000 during the first six months of 1997 which were on
target with expected results. Company personnel declined 57.3% from 213
employees at June 30, 1996 to 91 employees at June 30, 1997. This decrease in
personnel contributed to overall declines in expenses for both second quarter
1997 and year to date 1997.

 Cost of software revenues decreased 72.0% from $511,000 in the second quarter
of 1996 to $143,000 in the second quarter of 1997. Year to date, cost of
software revenues decreased 82.3% from $1,118,000 in 1996 to $198,000 in 1997.
This decrease is a result of a decrease in the amount of amortization of
capitalized software from $462,000 in the second quarter of 1996 to $126,000 in
the second quarter of 1997. The decrease in amortization resulted from the
Company's 1996 write-down of capitalized software costs relating to versions of
the Company's TakeControl and Brock Activity Manager product series to net
realizable value at December 31, 1996. Third party software and documentation
costs decreased 65.3% from $49,000 in the second quarter of 1996 to $17,000 in
the second quarter of 1997. For the first six months of 1997 third party
software and documentation costs have decreased 73.0% from $115,000 in 1996 to
$31,000 in 1997 as a result of fewer software licenses sold. Cost of software
revenues include costs of third party software, amortization of capitalized
software costs and costs of packaging and documentation materials and related
media costs.

Cost of revenues for services decreased 39.6% from $1,609,000 in the second
quarter of 1996 to $972,000 in the second quarter of 1997 due to decreases in
the number of service personnel and related costs. Year to date, costs of
revenues for services decreased 43.8% to $1,928,000 in 1997 from $3,430,000
during the same period of 1996. In the second quarter of 1996 service staff
numbered 67 employees compared to 32 employees during the second quarter of
1997. Costs of revenues for maintenance decreased 7.5% from $510,000 in the
second quarter of 1996 to $472,000 in the second quarter of 1997. Year to date,
costs of revenues for maintenance decreased 10.9% from $1,046,000 in 1996 to
$932,000 in 1997. The decrease is primarily due to decreases in support
personnel and personnel related costs.

Cost of other revenues decreased 11.9% from $194,000 in the second quarter of
1996 to $171,000 in the second quarter of 1997; and, year to date, decreased
33.5% from $495,000 in 1996 to $329,000 in 1997 due to a decrease in
reimbursable travel charges consistent with the decline in services revenue.

Sales and marketing expense decreased 36.9% from $2,393,000 in the second
quarter of 1996 to $1,511,000 in the second quarter of 1997. Year to date, sales
and marketing expense decreased 53.6% to $2,444,000 in 1997 from $5,272,000 in
1996. The decreases were primarily due to a decrease in commissions associated
with the decrease in software sales revenues. There were also decreases in
payroll, payroll associated costs, and travel expenses related to the decrease
in sales and marketing personnel from 53 employees at June 30, 1996, to 21
employees at June 30, 1997.

The Company's product innovation and development expenditures decreased 68.8%
from $1,281,000 in the second quarter of 1996 to $400,000 in the second quarter
of 1997. During the second quarter of 1996, $705,000 was capitalized; however,
no capitalization was recorded during the second quarter of 1997 because
development activities qualifying for capitalization were immaterial. Product
development expense, net of costs capitalized, decreased 30.6% from $576,000 in
the second quarter of 1996 to $400,000 in the second quarter of 1997 and year to
date decreased 15.2% to $924,000 in 1997 from $1,090,000 during the same period
of 1996. These decreases were due to the combination of no new costs being
capitalized and the decreases in development personnel, personnel related costs
and contract services.

General and administrative expenses decreased 33.5% to $699,000 in the second
quarter of 1997 from $1,051,000 in the second quarter of 1996. Year to date,
general and administrative expenses decreased 3.5% from $1,894,000 in 1996 to
$1,828,000 in 1997. The decreases resulted primarily from decreases in personnel
and personnel related costs including telephone and insurance.

The above factors combined to result in a decrease of approximately 59.6% in net
loss for the second quarter of 1997, from a loss of $604,000 in the second
quarter of 1996 to a loss of $244,000 in the second quarter of 1997. Net loss
per share for the period decreased from a loss of $0.12 per share for the second
quarter of 1996 to a loss of $0.05 for the second quarter of 1997.

BALANCE SHEET

Net accounts receivable decreased 38.7% from $4,120,000 at December 31, 1996, to
$2,524,000 at June 30, 1997, as a result of the collection of outstanding
receivables and the decrease in sales revenues for the first six months of 1997.
Accrued restructuring costs declined 46.5% from $1,111,000 at December 31, 1996
to $594,000 at June 30, 1997 as a result of payments made. The remaining accrual
includes $116,000 in severance payable through the end of year, and $478,000 in
costs associated with non-cancelable leases which will amortize over the
remaining life of the leases. The line of credit, short term note, and long term
note all decreased 100% with the March 21, 1997 payoff of all outstanding
balances.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1997, the Company had cash and marketable securities of $4,735,000
and believes that its present liquidity position is sufficient to finance the
Company's operations during 1997. During the first quarter of 1997, the Company
paid off, in full, its outstanding line of credit and note payable, and related
interest for a total of $2,199,657. This accounts for the decrease in cash and
marketable securities from $6,947,000 at December 31, 1996 compared to
$4,735,000 at June 30, 1997. The line of credit has been closed.

As of July 25, 1997, the Company has entered into an option to purchase an
internet based software company, Netgain Corporation. Option payments of
$285,000 have been made and additional option payments of $70,000 monthly will
be made until the exercise of the option, or January 31, 1998, whichever occurs
first. If the option is exercised, 200,000 shares of the Company's common stock
will be placed in escrow and will be released based upon achievement of targeted
revenues realized from sale of Netgain products. Additional shares may be issued
depending on the achievement of future revenues from sale of Netgain products.
The Company believes its current cash position is sufficient to fund its
operations as well as these option payments.

EXHIBIT 10.15

                                OPTION AGREEMENT


         This Option Agreement (the "Agreement") is made and entered into this
25th day of July, 1997 among Brock International, Inc., a Georgia corporation
("Brock"), and NetGain Corporation, a Georgia corporation ("NetGain"):

         For value received, and in consideration of the mutual covenants
contained herein, the parties hereto agree as follows:

                                    ARTICLE I
                             OPTION TO CAUSE MERGER

         1.1  Grant of Options. NetGain hereby grants to Brock, subject to the
terms and conditions hereinafter set forth, and in consideration of the payment
by Brock to NetGain, on the date hereof, of the sum of $200,000 by check
delivered to NetGain, an exclusive and irrevocable right and option (the
"Option") to require NetGain to approve the merger (the "Merger") of NetGain
into and with Brock Acquisition, Inc., a Georgia corporation and a newly formed,
wholly owned subsidiary of Brock (the "Subsidiary") pursuant to an Agreement and
Plan of Merger between Brock, NetGain and the Subsidiary in the form attached
hereto as Exhibit A (the "Merger Agreement"). Brock may exercise the option at
any time prior to the close of business on January 31, 1998 by giving written
notice of its exercise of the Option to NetGain, which notice shall state that
Brock is exercising the option and requiring the Board of Directors and
stockholders of NetGain to approve the Merger. Within three business days of
receipt of notice from Brock that it is exercising the Option, NetGain shall
cause its Board of Directors, either at a meeting duly called and held or by
unanimous written consent, to approve the Merger Agreement, and to cause a
special meeting of stockholders of NetGain to be held to approve the Merger,
which meeting shall be held as soon as practicable after approval of the Merger
by the Board of Directors of NetGain and, in any event, within 30 days after
exercise by Brock of the Option.

         1.1  Continuation of Option. In order to continue the Option in full
force and effect, on the third business day prior to the fifteenth or last day
of a month next following the Closing Date (as hereinafter defined) and on each
third business day prior to the fifteenth and last day of each month thereafter
until exercise, lapse or expiration of the Option, Brock shall pay to NetGain by
wire transfer (each payment hereinafter referred to as a "Bimonthly Payment" and
collectively as "Bimonthly Payments"), as payment for the continuation of the
Option, the sum of $35,000. If such wire transfer is not received by NetGain by
the close of business on the date it is due to be made, NetGain agrees to notify
Brock by telephone, followed by written notice sent to Brock by telecopy, as
provided in Section 9.4 hereof. Upon receipt of such notice of failure to
receive a Bimonthly Payment, Brock will have to the end of the next business day



<PAGE>   2


following such notice to cure the failure to make the Bimonthly Payment. If
Brock fails to make a bimonthly payment or fails to cure the nonreceipt of a
Bimonthly Payment as provided herein, the Option will lapse and will thereafter
be null and void. Brock shall not be obligated to exercise the Option and may
discontinue to make Bimonthly Payments provided for in this Section 1.2 and
allow the Option to lapse, provided, however, it shall give written notice of
such determination to NetGain at such time Brock determines to allow the Option
to lapse. In the event such written notice of Brock's determination to allow the
Option to lapse is given, Brock shall advance, as a loan to NetGain evidenced by
NetGain's promissory note (to be substantially in the form attached hereto as
Exhibit B) at the time such Bimonthly Payments shall have otherwise been due,
amounts equal to each of the next two Bimonthly Payments which would have been
due after the date of such notice of Brock's election to allow the Option to
lapse, including (i) one loan, in an amount equal to a Bimonthly Payment, to be
made by Brock to NetGain on February 11, 1998, provided that, between January 1,
1998 and January 15, 1998, the Option lapses or is otherwise not exercised by
Brock, and (ii) another loan, in an amount equal to a Bimonthly Payment to be
made by Brock to NetGain on February 24, 1998, provided that, after January 15,
1998, the Option lapses, expires or is otherwise not exercised by Brock.
NetGain's promissory note given in respect of all such advances shall be payable
in full 90 days after the notice by Brock of its determination to allow the
Option to 1.2 lapse, or with respect to the loans provided for in clauses (i)
and (ii), 90 days after each such loan.

         1.3 Issuance of Shares Upon Lapse or Expiration of the Option. If Brock
should fail to exercise the Option on or before its expiration date either by
reason of Brock's determination to allow the Option to lapse, a failure to make
a Bimonthly Payment or upon Brock's failure to exercise the Option, in
consideration of the payments theretofore made by Brock to NetGain (other than
the advances against NetGain's promissory note or notes, if any) NetGain shall
issue to Brock on the earlier of (i) receipt of notice from Brock of its
determination to allow the Option to lapse, or (ii) January 31, 1998, shares of
common stock, $.01 par value ("NetGain Common Stock"), which, at the time of
issue, shall represent 10% of the then fully diluted equity of NetGain. For
purposes of the immediately preceding sentence, "fully diluted equity of
NetGain" shall mean the sum of the number of outstanding shares of NetGain
Common Stock plus the number of shares of NetGain Common Stock issuable upon the
exercise of then outstanding options to purchase NetGain Common Stock or upon
the conversion or exercise of any other outstanding instruments or rights
entitling the holder thereof to purchase shares of NetGain Common Stock which
are outstanding on the date of such notice or such date. Brock acknowledges that
the shares of NetGain Common Stock which would be issued to it pursuant to this
Section 1.3 shall not have been registered under the Securities Act of 1933, as
amended, that Brock would acquire such shares for investment only and not with a
view toward the distribution thereof and that any disposition of such shares by
Brock will be made only in accordance with the registration provisions of the
Securities Act and applicable state securities or "blue sky" laws, or pursuant
to a valid exemption from registration under such laws.

         1.4 Delivery of Proxies. In order to ensure that Brock shall have the
right to cause the Board of Directors of NetGain to approve the Merger and to
call a special meeting of stockholders of NetGain to approve the Merger and to
cause the stockholders of NetGain to 


                                       2
<PAGE>   3


approve the Merger at such meeting, NetGain shall deliver to Brock on the
Closing Date, irrevocable proxies (individually a "Proxy" and collectively, the
"Proxies"), in the form attached hereto as Exhibit C, from stockholders of
NetGain holding at least a majority on the Closing Date of the issued and
outstanding shares of NetGain Common Stock on a fully diluted equity basis (and
including Proxies from those individuals whose names appear in Section 7.1(f)
hereof).

                                   ARTICLE II
                       THE MERGER AND THE MERGER AGREEMENT

         2.1 The Merger. In the event Brock exercises the Option, the Merger
shall occur as soon as practicable after approval of the Merger and the Merger
Agreement by the stockholders of NetGain. In such an instance, NetGain agrees to
execute and deliver the Merger Agreement and such other documents, certificates
and agreements as may be contemplated hereby or thereby or as shall be necessary
or appropriate in connection therewith in order to permit the filing of the
Merger Agreement with the Secretary of State of the State of Georgia as soon as
practicable after the approval of the Merger by the stockholders of NetGain.

         2.2 The Merger Agreement. The Merger shall occur pursuant to the Merger
Agreement, which shall be in the form attached hereto as Exhibit A. The Merger
shall become effective upon the filing of the Merger Agreement with the
Secretary of State of the State of Georgia, which date and time is hereafter
referred to as the "Effective Date of the Merger".

         2.3 The Escrow Agreement. As contemplated hereby and by the Merger
Agreement, each of the holders of NetGain Common Stock at the Effective Date of
the Merger shall enter into an escrow agreement (the "Escrow Agreement") in the
form attached hereto as Exhibit D providing for, among other things, the
delivery of shares of common stock, $.01 par value, of Brock ("Brock Common
Stock") issuable pursuant to the Merger Agreement into escrow under the terms of
the Escrow Agreement and for the indemnification by holders of NetGain Common
Stock of Brock from and against Undisclosed Liabilities (as defined in the
Escrow Agreement) of NetGain. In order to comply with its obligation to insure
execution and delivery by each of the holders of NetGain Common Stock of the
Escrow Agreement, between the date of the meeting of the Board of Directors of
NetGain to approve the Merger and the meeting of the stockholders of NetGain to
approve the Merger, NetGain shall cause the Escrow Agreement to be executed by
each of the holders of NetGain Common Stock, but shall hold the Escrow Agreement
for delivery to Brock upon the Effective Date of the Merger.

                                   ARTICLE III
                                   THE CLOSING

         3.1 The Closing. The closing of the Merger shall be held at the offices
of Powell, Goldstein, Frazer, and Murphy LLP in Atlanta, Georgia on the date of
the meeting of the 


                                       3
<PAGE>   4
NetGain stockholders to approve the Merger, immediately following such meeting,
at which time the documents to be delivered pursuant to this Agreement shall be
executed and delivered. Such date is referred to in this Agreement as the
"Closing Date".

referred to as the "NetGain Plans" and NetGain Plans together with any such
plans maintained by any entity which together with NetGain constitutes a single
employer within the meaning of Section 414 of the Internal Revenue Code of 1986

with NetGain constitutes a single employer within the meaning of the Code
(hereinafter referred to as the "NetGain Group") have no outstanding, present or
future obligation or liability to contribute to a multiemployer plan. If any
Group Plans were terminated on the Closing Date, no member of the NetGain Group
would have any liability as a result of the termination. Each member of the
NetGain Group has made full and timely payment of, or has accrued on its
financial statements, pending full and timely payments, all amounts which are
required under the terms of each NetGain Group Plan and in accordance with
applicable law for the plan year within which the Closing Date falls. No member
of the NetGain Group has any liability with respect to any NetGain Group Plan.
All NetGain Group Plan comply in all material respects with ERISA and, when

in substantial compliance with the requirements of ERISA and, when applicable,
with the requirements of the Code. Other than routine claims for benefits, there
are no actions, audits, investigations, suits, or claims pending, or threatened
against any of The NetGain Group Plans or any fiduciary of any of The NetGain
Group Plans or against the assets of any of The NetGain Group Plans. The

NetGain Group Plan which is intended to meet the requirements of Section 401(a)
of the Code, no member of NetGain Group has any obligation to any retired or
former employee, or any current employee upon retirement, under any NetGain

         (b) There exists no actual or, to the knowledge of NetGain, threatened
    termination, cancellation or limitation of, or any modification or change

    licensor to NetGain; and

         (c) There are no defaults or claims purported, or alleged defaults, or 
    any state of facts which, with notice, lapse of time or both, would
    constitute defaults under any obligations on the part of NetGain to be
    performed under any instruments, documents, agreements (oral or written) to
    which NetGain is a party, including, without limitation, any contracts or
    licenses, the consequences of which in the aggregate would cause material
    damage or additional costs and expenses to NetGain.

returns. Each such return is or will be true, correct and complete in all
material respects, and copies of such returns have been or will be provided to
Brock. NetGain agrees to capitalize all research and development expenditures
accrued for NetGain Products and any other accrued research and development
expenditures on its 1997 annual tax returns. As of the date hereof and as of the
Closing Date, NetGain has and will have accrued in accordance with generally
accepted accounting principles all taxes and governmental charges, including
deferred taxes, that are or will become due and payable with respect to its
operations through the Closing Date. All amounts required to be withheld by
NetGain from its employees (as classified for payroll tax purposes by the
appropriate governmental authority, without regard to the classification by
NetGain) for income tax, social security contributions, unemployment tax,
workers' compensation, or other employment tax purposes have been and will be
withheld and, if applicable, paid to the appropriate governmental agencies. The
transaction resulting in the acquisition by NetGain of all of its assets from

paid all income taxes, if any, that were due with respect to the Predecessor's
income for all periods prior to the Closing Date. No claim or assessment is
pending or, to the knowledge of NetGain, threatened against NetGain, the
Predecessor, or the members of the Predecessor. There are no pending or, to the
knowledge of NetGain, threatened audits of any tax return of NetGain, the
Predecessor, or the members of the Predecessor. Neither NetGain, the
Predecessor, or the members of the Predecessor have executed a waiver or consent
extending any statute of limitations for the assessment or collection of any
taxes which remains outstanding. NetGain is not, nor has it ever been, a member
of a consolidated group of corporations as defined in Section 1504 of the Code,
or comparable provision of the laws of any state.

                  in negotiations with any Person (as hereinafter defined),
                  whether such negotiations are initiated by NetGain or

                  of any Person, other than Brock, relating to the possible
                  acquisition of NetGain (whether by way of merger, purchase of
                  capital stock, purchase of assets or otherwise) or any
                  material portion of its capital stock or assets;

                                    (ii)provide information with respect to

                                    (iii) enter into any agreement with any
                  Person, other than Brock, providing for the possible
                  acquisition of NetGain (whether by way of merger, purchase of
                  capital stock, purchase of assets or otherwise) or any
                  material portion of its capital stock or assets; or

                  (b) If NetGain receives any unsolicited offer or proposal to
         enter into negotiations relating to the possible acquisition by NetGain
         by any person other than Brock, NetGain shall immediately notify Brock

         remedy at law for a breach or threatened breach by Brock of the terms
         of Section 6.5, and NetGain therefore

<PAGE>   19

         agrees that if it should breach its agreement contained in Section 6.5,

         intent between Brock and NetGain on July 9, 1997, upon execution of
         this Agreement and in respect of Bimonthly Payments, to reimburse Brock
         for the expenses Brock shall have incurred in connection with the
         transactions contemplated hereby and as partial reimbursement to Brock
         for its damages arising out of loss of bargain; provided, however, the
         right to receive such payment shall not be Brock's exclusive remedy for
         such breach and Brock shall have, in addition to the right to receive
         such payment, such other rights and remedies in respect of such breach
         as may be provided at law or in equity including, without limitation,

         such breach or the continuation thereof by NetGain.

customers and vendors and the use of NetGain's assets and its product
development activities) and NetGain shall promptly advise Brock in writing of
any change or event having, or which, insofar as can reasonably be foreseen,
could have, a material adverse effect on the business, operations, financial
condition or prospects of NetGain.

the Effective Date of the Merger or the earlier termination of this Agreement
pursuant to Article VIII hereof, NetGain agrees not to take or cause to be taken
any action which would reasonably be expected to have the effect of causing
Brock not to exercise the Option or which would cause the Merger not to be
consummated and NetGain agrees to use its reasonable best efforts to take, or
cause to be taken, all actions and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws or regulations to
consummate and make effective as promptly as practicable the transactions
contemplated by this Agreement.

required by law.

the other hand, shall pay the expenses (including legal fees and expenses)
incurred by Brock and NetGain, respectively, in connection with the transactions

such expenses incurred by NetGain through the Effective Date of the Merger,
should the Merger occur. On the Effective Date of the Merger, the stockholders
of NetGain shall have contributed to the capital account of NetGain such amount
as may be 



                                       19
<PAGE>   20


necessary to cause the accrued liabilities of NetGain on the Effective Date of
the Merger not to exceed payroll expenses of NetGain accrued since the last
Bimonthly Payment and up to $10,000 of other current liabilities incurred by
NetGain in the ordinary course of business, and such amount contributed by the
stockholders of NetGain to its capital account shall be used to discharge
liabilities of NetGain in excess of such amounts.

         6.10     Notification of Certain Matters.  NetGain shall give prompt 
notice to Brock of the occurrence, or failure to occur, of any event, which
occurrence or failure to occur would be likely to cause:

                                    (i) any representation or warranty contained
                  in this Agreement to be untrue or inaccurate in any respect

         that a stockholder of NetGain shall become an employee or stockholder
         of Brock on or after the Effective Date of the Merger shall in no way

         9.6   Benefits, Assignments.  This Agreement is not intended to confer 
against any Person other than the parties hereto any rights or remedies
hereunder and shall not be assigned by operation of law or otherwise.

         9.7  Governing Law.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of Georgia applicable to contracts made
and to be performed therein.

         9.8  Construction. The language used in this Agreement will be deemed 
to be the language chosen by the parties to express their mutual intent, and no
rule of strict construction shall be applied against any party. Nothing in any
schedule delivered to Brock pursuant to this Agreement shall be deemed adequate
to disclose an exception to a representation or warranty made herein unless such
schedule identifies the exception with particularity and describes the relevant
facts in detail. Without limiting the generality of the foregoing, the mere
listing (or inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made herein
(unless the representation or warranty has to do with the existence of the
document or other items themselves). 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.

         9.9  Arbitration. Except for the equitable remedies provided for in 
this Agreement, the parties hereto have agreed to settle all disputes by binding
arbitration by a single arbitrator in accordance with the rules of the American
Arbitration Association.
