                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of July 10,
1998, is made and entered into between BLUE RIDGE INVESTORS LIMITED PARTNERSHIP,
a North Carolina limited partnership (the "Purchaser") which is a Federal
Licensee under the Small Business Investment Act of 1958, as amended (the "SBIC
Act"); I 3S, INC., a Texas corporation (the "Company"); JAMES R. PRICE, GARY A.
DOBBINS, CLAY C. SCOTT, JR., CHARLES BO PRICE, GEORGE VENNER, and I3S FUNDING I,
L.L.C. ("Funding") the sole existing holders of capital stock of the Company
(the "Shareholders") who execute this Agreement solely for the purpose of
agreeing to the provisions of Section 2 hereof and waiving any and all
preemptive rights with respect to the issuance of the Class C Shares hereunder.

         Purchaser wishes to purchase from the Company, and the Company wishes
to sell to Purchaser, 875,000 shares of the Company's Class C Common Stock, no
par value per share (the "Class C Shares"), on the terms and conditions set
forth herein.

         NOW, THEREFORE, in consideration of the mutual agreements,
representations and warranties contained in this Agreement, the parties hereto
agree as follows:

1. SALE AND PURCHASE OF CLASS C SHARES; THE CLOSING

         a. Sale and Purchase of Class C Shares. Subject to the terms and
conditions set forth in this Agreement, at the Closing provided for in paragraph
1.d. below, the Company shall sell to Purchaser, and Purchaser shall buy from
the Company, Eight Hundred Seventy Five Thousand (875,000) Class C Common Shares
for an aggregate purchase price of One Million Seven Hundred Fifty Thousand
Dollars ($1,750,000). The Class C Shares shall represent at the time of issuance
6.5029% of all outstanding common stock of the Company on a fully diluted basis
(i.e. calculated as

<PAGE>   2

if all outstanding options, warrants or other rights to acquire or purchase
shares of the Company's common stock, had been exercised).

         b. Payment of Purchase Price. At the Closing, Purchaser shall deliver
the sum of One Million Seven Hundred Fifty Thousand Dollars ($1,750,000) to the
Company by way of a wire transfer in complete payment for the Class C Shares.

         c. Delivery of Stock Certificate. In consideration for Purchaser's
payment for the Class C Shares, at the Closing the Company shall deliver to
Purchaser a stock certificate representing the Class C Shares.

         d. The Closing. The closing of the sale and purchase of the Class C
Shares contemplated hereby (the "Closing"), shall take place at the offices of
the Company, 1330 River Bend, Suite 600, Dallas, Texas, at 10:00 a.m. on the
date hereof, or such other date and time as Purchaser and the Company shall
mutually agree in writing (the "Closing Date"). At the Closing, the Company
simultaneously shall sell 875,000 shares of Class C Common Stock to Spotswood
Capital, LLC ("Spotswood") for $1,750,000 on substantially the same terms and
conditions that are set forth herein with respect to the sale of the Class C
Shares to Purchaser.

2. PREFERENCES, LIMITATIONS AND RELATIVE RIGHTS OF THE CLASS C SHARES

         a. Voting. Except as provided in Section 2.i below, the Class C Shares
shall be entitled to vote on all matters voted on at a shareholders' meeting,
with the same voting rights per share as are granted to the Company's Class A
Common Stock and Class B Common Stock. Purchaser acknowledges that 258,521 of
the Class C Shares shall be transferred to a voting trust pursuant to a Voting
Trust Agreement to be executed and delivered at Closing substantially in the
form of Exhibit A attached hereto.

                                        2

         b. Preemptive Rights. Until such time as a Purchaser Approved Offering
(as defined below) has been consummated or Purchaser has otherwise sold all of
its Class C Shares or other equity interests in the Company, Purchaser shall
have preemptive rights with regard to any future issuances of common stock of
the Company (other than an issuance of common stock pursuant to options that are
approved by the holders of the Company's Class B Common Stock) permitting
Purchaser to purchase additional common shares pro rata at the same price and on
the same terms and conditions of such issuance; provided, however, that if the
holders of the Company's Class B Common Stock waive their rights with respect to
a future issuance of common stock, Purchaser shall not have preemptive rights
with respect to that issuance. For purposes of this Agreement, a Purchaser
Approved Offering shall mean the consummation of an underwritten public offering
of common stock of the Company on the New York Stock Exchange, the American
Stock Exchange, or The Nasdaq Stock Market, Inc. pursuant to a registration
statement filed with the Securities and Exchange Commission under the Securities
Act of 1933, as amended (the "1933 Act"), covering the offer and sale of common
stock of the Company to the public at a price resulting in gross proceeds from
such sale to the Company (before deduction of underwriting discounts and
expenses of sale) of not less than $50,000,000.

         c. Right of First Refusal. Except in the event of and after the
consummation of a Purchaser Approved Offering, and except for gifts, charitable
donations or sales in each case representing less than One Percent (1%) of the
Company's outstanding common stock in the aggregate, no shareholder shall be
permitted to dispose of any shares of the Company's common stock unless such
shares shall have been offered for sale in writing first to the Company and then
to the other shareholders of the Company pro rata. In the event a shareholder
desires to transfer any

                                        3

<PAGE>   4

common shares, the shareholder desiring to make such transfer (the "Transferring
Shareholder") shall deliver written notice (the "Offer Notice") to the Company
and to all other shareholders at least sixty (60) days prior to the proposed
transfer. The Offer Notice will disclose in reasonable detail the proposed
number of shares to be transferred, the proposed transferee and the proposed
price, terms and conditions of the transfer.

                  i. Upon receipt of the Offer Notice, the Company shall have
the option (the "Company's Option") for a period of thirty (30) days to purchase
or otherwise acquire all or part of the shares described in the Offer Notice for
an aggregate amount (such aggregate amount being hereinafter referred to as the
"Option Price") equal to the bona fide purchase price to be paid by the proposed
purchaser as described in the Offer Notice (which amount shall be zero if the
proposed transfer would take the form of a gift or other gratuitous transfer).
The Company shall notify in writing all then current shareholders as to whether
it will exercise, partially exercise or not exercise the Company's Option before
the expiration of the Company's Option.

                  ii. In the event that the Company does not elect to fully
exercise the Company's Option within thirty (30) days after receipt of the Offer
Notice, the remaining shareholders shall have the option (each a "Shareholder's
Option") for a period of ten (10) days from the earlier of (i) their receipt of
written notice from the Company of its decision not to exercise or to only
partially exercise the Company's Option, or (ii) the expiration of the Company's
Option (the "Other Shareholder Election Period"), to purchase or otherwise
acquire all or part of the remaining shares which the Company does not choose to
purchase pursuant to the Company's Option, in proportion to their respective
ownership of shares which, for purposes of such determination, shall include
without duplication all outstanding options, warrants or other rights owned by
such shareholders that are

                                        4

<PAGE>   5

convertible into shares as of the date of such notice from the Company (or the
expiration of the Company's Option), for an amount equal to the applicable
portion of the Option Price. Each shareholder shall notify in writing all then
current shareholders as to whether such shareholder will exercise, partially
exercise or not exercise the shareholder's option before the expiration of the
Other Shareholder Election Period.

                  iii. For a period of ten (10) days from the earlier of (i) the
receipt by the other shareholders of a written notice from a shareholder that it
does not want to exercise its option or will only partially exercise its option,
or (ii) the expiration of the Other Shareholder Election Period, the other
shareholders shall have the right to purchase or otherwise acquire such
shareholder's portion of the shares described in the Offer Notice in proportion
to their respective ownership of shares (determined as described in Section
2.c.ii. above).

                  iv. If shares of a Transferring Shareholder remain unsold
after compliance with the procedures set forth in this Section 2.c., the Company
shall have the final option for ten (10) days to purchase or otherwise acquire
all of the remaining shares proposed to be transferred for an amount equal to
the applicable portion of the Option Price. If, however, the Company and the
other shareholders do not individually or collectively elect to purchase all of
the shares being offered, the Transferring Shareholder may, within thirty (30)
days after the expiration of the Other Shareholder Election Period (subject to
the provisions of Section 2.c.vi. below), transfer all of the shares specified
in the Offer Notice to the transferee identified in the notice at the price and
terms stated in the Offer Notice. Any shares so transferred thereupon shall
continue to be subject to this Agreement, and the transferee shall have the
rights and obligations set forth in this Agreement hereunder with respect to
such shares. If the Transferring Shareholder fails to consummate such transfer
within the thirty-day

                                       5
<PAGE>   6

period after the expiration of the Other Shareholder Election Period, any
transfer of the shares thereafter shall again be subject to the provisions of
this Section 2.c.

                  v. Unless otherwise agreed in writing, signed by the person
against whom such writing is sought to be enforced, the closing of any
acquisition of common shares hereunder pursuant to the Company's Option or a
Shareholder's Option shall take place within forty-five (45) days of an
applicable option's exercise. If any such closing does not take place within
such forty-five day period, then the shares that were to be acquired shall be
offered in accordance with this Section 2.c.
as though the applicable option had not been exercised.

                  vi. Notwithstanding the foregoing provisions of this Section
2.c., the following shall apply in the event of any Involuntary Transfer of
common shares. An "Involuntary Transfer" shall mean any transfer caused by the
death of a shareholder, as well as any transfer, proceeding or action by,
through, as a consequence of, or in which a shareholder shall be deprived or
divested of any right, title or interest in or to any of the common stock of the
Company, including, without limitation, any seizure under levy, attachment or
execution, any transfer in connection with bankruptcy (whether pursuant to a
filing of a voluntary or an involuntary petition under the United States
Bankruptcy Code, or any amendments, modifications, revisions or successors
statutes thereto) or other court proceeding to a debtor-in-possession, trustee
in bankruptcy or receiver or other officer or agency, any transfer to a state or
to a public officer or agency pursuant to any statute pertaining to escheat or
abandoned property, any transfer pursuant to a separation agreement, equitable
distribution agreement or community property distribution agreement, or the
entry of a final court order in a divorce proceeding from which there is no
further right of appeal.

                                       6
<PAGE>   7

                  In the event of any Involuntary Transfer, the Company shall
give written notice to each shareholder upon the occurrence, or prospective
occurrence, of such Involuntary Transfer within fifteen (15) days of the date on
which the Company is notified of the occurrence or prospective occurrence of
such Involuntary Transfer. The foregoing provisions of this Section 2.c. then
shall apply, except (i) the Option Price shall be the value of the Company as
determined by a qualified representative of a nationally recognized investment
banking or accounting firm mutually agreeable to the Company, Purchaser, and the
shareholder who made, or may make, the Involuntary Transfer, multiplied by the
percentage of all equity interests in the Company that is then represented by
the shares that are the subject of the Involuntary Transfer, such independent
appraised value to take into account the earnings and book value of the Company,
and (ii) the appraiser shall deliver written notice of such valuation to the
Company and to all other shareholders promptly following his completion of such
valuation, and such written notice shall be considered the Option Notice for
purposes of this Section 2.c. The cost of the appraisal shall be shared equally
by the Company and the shareholder who made, or may make, the Involuntary
Transfer.

                  At the closing of any purchase by the Company or any
shareholders pursuant to this Section 2.c.vi., the involuntary transferee shall
deliver certificates representing the common shares being purchased, duly
endorsed for transfer and accompanied by all requisite stock transfer taxes, and
such shares shall be conveyed free and clear of any liens, claims, options,
charges, encumbrances or rights of others arising through the action or inaction
of the involuntary transferee, and the involuntary transferee shall so represent
and warrant. The involuntary transferee shall further represent and warrant that
he is the beneficial owner of such shares.

                                       7
<PAGE>   8

                  In the event the provisions of this Section 2.c.vi. shall be
held to be unenforceable with respect to any particular Involuntary Transfer of
common stock, or if all of the shares subject to the Involuntary Transfer are
not purchased by the Company and/or one or more shareholders, and if the
involuntary transferee subsequently desires to transfer such common stock, the
involuntary transferee shall be deemed to be a "Transferring Shareholder" under
Section 2.c. and shall be bound by the other provisions of this Agreement.

                  vii. Notwithstanding anything to the contrary contained in
this Section 2.c., no shareholder shall transfer any common shares at any time
if such action would constitute a violation of any federal or state securities
laws or a breach of the conditions to any exemption from registration of the
shares under any such laws or a breach of any undertaking or agreement of such
shareholder entered into pursuant to such laws or in connection with obtaining
an exemption thereunder. Each shareholder agrees that any shares purchased or
acquired by such shareholder shall bear appropriate legends restricting the sale
or other transfer of such shares in accordance with applicable federal and state
securities laws, in addition to a legend referring to the restrictions set forth
in this Agreement.

         d. Rights With Regard to Registration of Purchaser's Common Shares.

                  i. In the event that the Company registers any of its common
stock or other securities under federal and state securities laws for a primary
offering or a secondary offering by the Company or any of the officers or
directors of the Company who are also shareholders (a "Management Shareholder"),
Purchaser shall have piggy-back registration rights to include all common stock
then owned by Purchaser (collectively, the "Purchaser's Common Shares"), in any
such offering on a pro rata basis. The Company shall give Purchaser notice of
such proposed registration at least thirty (30) days prior to the filing of a
registration statement. Upon the written

                                       8
<PAGE>   9

request of Purchaser delivered to the Company within twenty (20) days after the
receipt of the notice from the Company, which request shall state the number of
Purchaser's Common Shares that Purchaser wishes to sell or distribute publicly
under the registration statement proposed to be filed by the Company, the
Company shall use its best efforts to register Purchaser's Common Shares, and to
cause such registration to become and remain effective so long as the Company
keeps such registration effective as to any other common stock of the Company.
Purchaser's Common Shares registered pursuant to this Section 2.d.i. must be
purchased and offered for sale by a bona fide underwriter or underwriters in a
public offering on a firm commitment basis. The Company's managing underwriter
shall have the right to limit in whole or in part the total number of
Purchaser's Common Shares to be sold hereunder, so long as such limitation is
applied on a pro rata basis with respect to all shares proposed or requested to
be registered by the Company and all shareholders. The expenses of any such
offering shall be borne by the Company, except for Purchaser's pro rata share of
any underwriter's discount or sales agent's commission.

                  ii. If, in connection with any registration under this Section
2.d, any of the common shares of Company stock require registration or
qualification under the securities or "blue sky" laws of any state, or the
approval of any state governmental official or authority, the Company shall take
all requisite action and use its best efforts to cause such shares to be duly
registered, qualified or approved as may be required. If any shares meet the
criteria for listing on any exchange on which such stock of the Company is then
listed, the Company shall apply for and use its best efforts to obtain a listing
of all such shares on such exchange.

                  iii. Except as provided in Section 2.d.i. above, the Company
shall pay all of the expenses in connection with the registration of any shares
of Company stock, including, without

                                       9
<PAGE>   10

limitation, the costs of preparing, printing and filing the registration
statement in compliance with the 1933 Act, the fees and expenses of counsel and
accountants for the Company, Management Shareholders and Purchaser for
qualifying the offering under the securities or "blue sky" laws and regulations
of the state in which the offering is qualified.

         e. Sale of the Company.

                  i. At any time after April 4, 2000, and before the
consummation of a Purchaser Approved Offering, if a bona fide offer is made by
any person (other than Purchaser, or any person or entity related to or
affiliated with Purchaser), to purchase all or substantially all of the assets
or shares of stock of the Company, and Funding gives the Company written notice
that it desires such offer to be accepted, the Company and its shareholders
shall either accept the offer and consummate the sale on the terms and
conditions of the offer (in which case, if the transaction is a stock sale or
merger, Purchaser also shall sell all of its equity interests in the Company on
those terms and conditions), or the Company shall acquire all the equity
interests owned by Purchaser and Funding in the Company on the same terms and
conditions as the offer; provided, however, that if such offer is made prior to
April 4, 2002, the Company shall have no such obligation unless the total
consideration of such offer is at least $50,000,000. If at any time Funding
approves the sale of substantially all of the assets or shares of stock of the
Company, then Purchaser shall vote its shares in favor of the transaction so
approved and, if the transaction is a stock sale or merger, shall sell all of
its equity interests in the Company on the terms and conditions so approved.

         In determining the total consideration for purposes of the foregoing,
any deferred payment shall be discounted to present value at a discount rate of
eight percent (8%) per annum. If the total consideration set forth in the offer
includes anything other than cash and/or marketable securities (the

                                       10
<PAGE>   11

"Non-Cash Consideration") then the Company, at its option, may acquire
Purchaser's equity interests for the product of (a) either (i) the Non-Cash
Consideration specified or (ii) cash in the amount of the fair market value of
the total consideration set forth in the offer, multiplied by (b) the percentage
of all outstanding equity interests of the Company that then is owned by
Purchaser. Such fair market value shall be determined pursuant to the terms of
the Stock Purchase Agreements dated April 4, 1997 and March 31, 1998 by and
among the Company, Funding and the other stockholders of the Company (the
"Funding Purchase Agreements").

         If the offer contemplates an asset sale, the Company may acquire
Purchaser's equity interests for cash equal to the product of (a) the after-tax
value to the Company of the consideration set forth in the offer multiplied by
(b) the percentage of all outstanding equity interests of the Company that is
then owned by Purchaser. If the Company decides to acquire Purchaser's and
Funding's equity interests, the Company shall acquire Purchaser's and Funding's
equity interests for cash within ninety (90) days from the date of Funding's
written notice.

                  ii. At any time before the consummation of a Purchaser
Approved Offering, if any assets or stock of the Company is sold for any reason,
or if the Company is merged or consolidated, then the following payments (the
"Management Shareholder Payments") to the Management Shareholders in connection
with such sale, merger or consolidation shall be deemed, for purposes of this
Agreement, as part of the total consideration to be paid for the Company so that
Purchaser shall be entitled to receive from the Company, pari passu with the
rights of holders of the Company's Class B Common Stock and all other holders of
the Company's Class C Common Stock to be paid with respect to the Management
Shareholder Payments, and before any distribution to shareholders, a priority
distribution equal to the product of (1) the sum of (a) all payments made to

                                       11
<PAGE>   12

a Management Shareholder in consideration of any covenant not to compete or
consulting agreement, plus (b) the component of any compensation to a Management
Shareholder for employment services that is in excess of the prevailing industry
average compensation, paid by companies that are similar to the company that
will be making the payments to the Management Shareholder, for the management
responsibilities actually to be performed by the Management Shareholder, as such
average compensation is mutually agreed between the Company, the Management
Shareholder and Funding, or if they cannot agree, then as determined by a
current survey of total compensation conducted by a qualified representative of
a nationally recognized investment banking or accounting firm mutually agreeable
to the Company, the Management Shareholder, and Funding, multiplied by (2) the
percentage of all equity interests in the Company that is then owned by
Purchaser.

         The priority distribution due Purchaser under this Paragraph 2.e.ii.
shall be paid on the same schedule as the Management Shareholder Payments are
received by the Management Shareholder. If the Company has insufficient funds to
pay the portion of the priority distribution that is due at the time a
Management Shareholder receives a Management Shareholder Payment, the Management
Shareholders receiving Management Shareholder Payments shall pay Purchaser the
amount of such insufficiency pro rata in accordance with the proportionate
amounts of each such Management Shareholder's Payments, such amount to be paid
on the same schedule as the payments are received by the Management Shareholder.

         f. Right of Co-Sale. In addition to the rights set forth in Section
2.c, at any time prior to the consummation of a Purchaser Approved Offering,
Purchaser shall have the right to participate pro rata to the full extent of its
equity interest in the Company in any sale or transfer of stock, other

                                       12
<PAGE>   13

than a gift, charitable donation or other sale or transfer representing less
than One Percent (1%) of the Company's outstanding common stock, by the Company
or any shareholder of the Company.

         g. Rights of Class C Shares on Liquidation, Dissolution or Winding Up.
The following provisions shall apply until the earlier of (i) the consummation
of a Purchaser Approved Offering, or (ii) the redemption or conversion of all
outstanding shares of the Company's Class C Common Stock:

                  i. In the event of any liquidation, dissolution or winding up
of the Company (including without limitation a liquidation or reorganization
under Chapter 11 of the United States Bankruptcy Code of 1978, as amended and as
may hereafter be amended), (a "Liquidation"), after payment of any priority
distributions due to Purchaser under Section 2.e.ii. above, the holders of the
Company's Class C Common Stock then outstanding shall be entitled to be paid out
of the assets of the Company available for distribution to its shareholders
(pari passu with the holders of the Company's Class B Common Stock, and before
any payment shall be made to the holders of any shares of the Company's Class A
Common Stock) an amount equal to the stated value of $2.00 (subject to
appropriate adjustment for stock dividends, stock splits, combinations, and
similar recapitalizations affecting the Company's Class C Common Stock) per
share of the Company's Class C Common Stock (the "Stated Value"), with such
amount to be calculated as of the date of such payment.

                  ii. If, upon any Liquidation, the assets of the Company
available for distribution to its shareholders shall be insufficient (a
"Liquidation Insufficiency") to pay the holders of the Company's Class C Common
Stock and Class C Common Stock the full amount to which they shall be entitled
pursuant to Section 2.g.i., the

                                       13
<PAGE>   14

holders of the Company's Class B Common Stock and the holders of the Company's
Class C Common Stock shall be entitled to receive, pari passu, all the assets of
the Company available for distribution to its shareholders.

                  iii. If there is no Liquidation Insufficiency and payment
shall have been made to the holders of the Company's Class B Common Stock and
the holders of the Company's Class C Common Stock of the full amount to which
they are entitled, the holders of the Company's Class B Common Stock and the
holders of the Company's Class C Common Stock shall then be entitled to share in
all remaining assets and funds of the Company ratably in proportion to the
number of shares of Company common stock held by such holder.

                  iv. Unless such transaction is approved by the directors
elected by the holders of the Company's Class B Common Stock, the merger or
consolidation of the Company into or with another corporation in which the
stockholders of the Company shall own less than Fifty Percent (50%) of the
voting securities of the surviving corporation or the sale, transfer or lease
(but not including a transfer or lease by pledge or mortgage to a bona fide
lender) of all or substantially all of the assets of the Company shall be deemed
to be a Liquidation as such term is used in this Section 2.g. The amount deemed
distributed to the holders of the Company's Class B Common Stock and the holders
of the Company's Class C Common Stock upon any such merger or consolidation
shall be the cash or the value of the property, rights or securities distributed
to such holder by the acquiring person, firm or other entity. The value of such
property, rights or other securities shall be determined by a competent
independent appraiser mutually agreed upon by the holders of the Company's Class
B Common Stock and the Company. The Company shall, upon receipt of such
appraiser's valuation, give prompt written notice of the appraiser's valuation
to the holders of the Company's Class B Common Stock and the holders of the
Company's Class C Common Stock. The fees of such

                                       14
<PAGE>   15

appraiser shall be shared 50% by the Company, and 50% (shared pro rata) by the
holders of the Company's Class B Common Stock and the holders of the Company's
Class C Common Stock.

                  v. The Company's Articles of Incorporation shall contain
provisions consistent with this Section 2.g. until the earlier of (i) the
consummation of a Purchaser Approved Offering, or (ii) the redemption or
conversion of all outstanding shares of the Company's Class C Common Stock.

         i. Representation on the Board of Directors; Visitation Rights. Until a
Purchaser Approved Offering has been consummated or Purchaser no longer owns any
equity interest in the Company, there shall be, and the Company's Articles of
Incorporation shall provide for, at least five (5) members on the Company's
Board of Directors, two (2) of whom shall be elected by the holders of the
Company's Class B Common Stock voting as a class, and the remainder of whom
shall be elected by the holders of the Company's Class A Common Stock voting as
a class. The holders of the Company's Class B Common Stock shall have the right
to remove and replace two (2) members of the Board at any time, and the holders
of the Company's Class A Common Stock shall have the right to remove and replace
the remaining members of the Board at any time. The Company shall pay each
director elected by the holders of the Company's Class B Common Stock a fee of
Two Thousand Five Hundred Dollars ($2,500.00) for attendance at each meeting of
the Board of Directors. Board meetings will occur at least quarterly. The
holders of the Company's Class C Common Stock shall have the right to appoint a
representative who shall have the right to attend meetings of the Company's
Board of Directors as a visitor.

3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         In connection with the purchase of the Class C Shares hereunder, the
Company hereby represents and warrants to Purchaser as follows:

outside accounting firm designated by the Company and reasonably acceptable to

         d. Other Deliveries. The Company shall deliver to Purchaser the

         f. Activities and Proceeds.

                  (i) Neither the Company nor any of its subsidiaries will
         engage in any activities or use directly or indirectly the proceeds
         from the Class C Shares for any purpose for which a small business
         investment company is prohibited from providing funds by the SBIC Act
         and the regulations promulgated thereunder, including Title 13, Code of
         Federal Regulations, Section 107.

                                       32
<PAGE>   33

                  ii. The Company will use the proceeds from the Class C Shares
         to provide working capital to develop existing and future projects. The
         Company will deliver within ninety (90) days of the Closing to
         Purchaser a written report, certified as correct by the Company's chief
         financial officer, verifying the purposes and the amounts for which
         proceeds from the Class C Shares have been disbursed, and, if the
         proceeds have not been fully disbursed within that ninety-day period,
         an additional report also so certified, delivered not later than the
         end of each succeeding ninety-day period, verifying the purposes and
         the amounts for which proceeds have been disbursed. The Company will
         supply to Purchaser such additional information and documents as
         Purchaser reasonably requests with respect to use of proceeds and will
         permit Purchaser to have access to any and all Company records and
         information and personnel as Purchaser deems necessary to verify how
         proceeds have been or are being used and to assure that the proceeds
         have been used for the purposes specified. The Company agrees that any
         diversion by the Company of the proceeds of the Class C Shares for any
         purpose other than those set forth above, without the prior written
         consent of Purchaser, will constitute a breach of the covenants of the
         Company under this Agreement (a "Proceeds Event of Default").

                  iii. The Company will not, without obtaining the prior written
         approval of Purchaser, change within one (1) year of the Closing the
         Company's business activity from that described above to a business
         activity which a small business investment company is prohibited from
         providing funds by the SBIC Act and the regulations promulgated
         thereunder. The Company agrees that any such changes in its business
         activity without such prior written

                                       33
<PAGE>   34

         consent of Purchaser will constitute a breach of the covenants of the
         Company under this Agreement (an "Activity Event of Default").

                  iv. If either a Proceeds Event of Default or an Activity Event
         of Default occurs, Purchaser hereunder shall have the right to demand
         immediate repayment of the purchase price of the Class C Shares,
         together with interest at the rate of 12% per annum to the date of
         repayment, and the Company will immediately make such payment within
         three (3) days of receipt of a demand. The payment remedy is in
         addition to any and all other rights and remedies against the Company
         and others to which Purchaser may be entitled.

                                       40
<PAGE>   41

12. CLAIMS FOR INDEMNIFICATION

          Any claim for indemnification which is based upon a final judgment,
decree or award of a court of competent jurisdiction requiring the payment of
money by any party to this Agreement or any of its officers, directors or
controlling persons, shall be conclusive as to the amount of such claim,
provided a certified copy of such judgment, decree or award accompanies the
notice relating to such claim and provided further that the party seeking
indemnification shall have complied with Section 14 of this Agreement.

         Any claim for indemnification shall be conclusive in all respects
thirty (30) days after receipt by the other party of notice thereof, unless
within such period the indemnifying party shall have sent to the party seeking
indemnification, and the party seeking indemnification shall have received,
notice questioning the propriety of the claim, in which case such claim, unless
settled by agreement of the parties, shall be promptly referred to arbitration
as provided in Section 13. In the event that a party makes a claim for
indemnification, and the indemnifying party contests that claim but the claim is
not settled or referred to arbitration within sixty (60) days after receipt by
the indemnifying party of notice of the claim from the party seeking
indemnification, such claim shall be regarded as conclusive in all respects.

13. DISPUTE RESOLUTION

         All disputes arising hereunder between the parties shall be referred to
arbitration under the Uniform Arbitration Act as adopted in Delaware, according
to the rules of the American Arbitration Association. Judgment upon the award by
the arbitrator may be entered in any court having jurisdiction thereof. As part
of such award, the arbitrator shall be promptly paid by the party that initiates
the proceeding, but the portion of each such fee and expenses which represents
the same

                                       41
<PAGE>   42

percentage thereof as the percentage of the amount of the claim represented by
the amount awarded shall be added to the amount of the award and shall be borne
by the indemnifying party. Any award shall be a conclusive determination of the
matter and shall be binding upon Purchaser and the Company and shall not be
contested by either of them. Arbitration proceedings shall be held in the city
of Dover, Delaware unless the parties agree upon another location. In any such
action the prevailing party, in the judgment of the arbitrator, shall be
entitled to an award of its costs and attorneys' fees incurred in the action.

14. THIRD PARTY CLAIMS

         In the event that any legal proceeding shall be instituted, or any
claim or demand shall be asserted, by any third party in respect of which
indemnity may be sought by Purchaser or the Company pursuant to the provisions
of this Agreement, the party seeking indemnification, with reasonable promptness
after obtaining knowledge of such proceeding, claim or demand shall give written
notice thereof to the other party, who shall then have the right, at its option
and expense, to be represented by counsel of its choice in connection with such
matter, which counsel shall be reasonably satisfactory to the party seeking
indemnification, and to defend against, negotiate, settle or otherwise deal with
any such proceeding, claim or demand; provided, however, that without the prior
written consent of the party seeking indemnification, which consent shall not be
unreasonably withheld, the indemnifying party shall not consent to the entry of
any judgment in or agree to any settlement of any such matters; and provided
further that the party seeking indemnification may retain counsel, at its own
expense, to represent it and participate in connection with any such proceeding
or claim or demand. Failure by the indemnifying party to notify the party
seeking indemnification of the indemnifying party's election to defend any
proceeding, claim or demand with respect to which

                                       42
<PAGE>   43

indemnity is sought within thirty (30) days after notice thereof shall have been
given by the party seeking indemnification shall be deemed a waiver by the
indemnifying party of its right to defend against such matter. If the
indemnifying party assumes defense of any such proceeding, claim or demand, it
shall take or cause to be taken all steps necessary in connection with such
defense, and the party seeking indemnification shall in all events be entitled
to indemnity with respect to such matter, as provided in this Agreement. In the
event that the indemnifying party does not elect to defend any proceeding, claim
or demand with respect to which indemnity is sought, the party seeking
indemnification may defend against, settle or otherwise deal with any such
proceeding, claim or demand in such matter as it may in its good faith
discretion deem appropriate and the indemnifying party shall be liable for
indemnification with respect to such matter, including without limitation the
reasonable costs of such defense, as provided in this Agreement. In the event of
any proceeding, claim or demand by a third party with respect to which a claim
for indemnification is made hereunder, the parties hereto agree that they will
cooperate fully with each other in connection with the defense or settlement of
such matter.

waiver or failure to insist upon strict compliance with such obligation,
agreement or condition shall not operate as a waiver of, or estoppel with

<PAGE>   44

                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of December
30, 1998, is made and entered into between SPOTSWOOD CAPITAL, LLC, a North
Carolina limited liability company (the "Purchaser"); I 3S, INC., a Texas
corporation (the "Company"); JAMES R. PRICE, GARY A. DOBBINS, CLAY C. SCOTT,
JR., CHARLES BO PRICE, GEORGE VENNER, BLUE RIDGE INVESTORS LIMITED PARTNERSHIP
("Blue Ridge") and I3S FUNDING I, L.L.C. ("Funding") (collectively, the
"Shareholders") who execute this Agreement solely for the purpose of agreeing to
the provisions of Section 2 hereof and waiving any and all preemptive rights
with respect to the issuance of the Class C Shares hereunder.

         Purchaser wishes to purchase from the Company, and the Company wishes
to sell to Purchaser, 162,232 shares of the Company's Class C Common Stock, no
par value per share (the "Class C Shares"), on the terms and conditions set
forth herein.

         NOW, THEREFORE, in consideration of the mutual agreements,
representations and warranties contained in this Agreement, the parties hereto
agree as follows:

1.       SALE AND PURCHASE OF CLASS C SHARES; THE CLOSING

         a. Sale and Purchase of Class C Shares. Subject to the terms and
conditions set forth in this Agreement, at the Closing provided for in paragraph
1.d. below, the Company shall sell to Purchaser, and Purchaser shall buy from
the Company, One Hundred Sixty Two Thousand Two Hundred Thirty-Two (162,232)
Class C Shares for an aggregate purchase price of Five Hundred Thousand Dollars
($500,000). The Class C Shares, together with the Class C Common Stock
previously issued to Purchaser, shall represent at the time of issuance 7.10% of
all outstanding common stock of the Company on a fully diluted basis (i.e.
calculated as if all outstanding options,

<PAGE>   2

warrants or other rights to acquire or purchase shares of the Company's common
stock, had been exercised).

         b. Payment of Purchase Price. At the Closing, Purchaser shall deliver
the sum of Five Hundred Thousand Dollars ($500,000) to the Company by way of a
wire transfer in complete payment for the Class C Shares.

         c. Delivery of Stock Certificate. In consideration for Purchaser's
payment for the Class C Shares, at the Closing the Company shall deliver to
Purchaser a stock certificate representing the Class C Shares.

         d. The Closing. The closing of the sale and purchase of the Class C
Shares contemplated hereby (the "Closing"), shall take place at the offices of
the Company, 1330 River Bend, Suite 600, Dallas, Texas, at 10:00 a.m. on the
date hereof, or such other date and time as Purchaser and the Company shall
mutually agree in writing (the "Closing Date"). At the Closing, the Company
simultaneously shall sell (i) 162,232 shares of Class C Common Stock to Blue
Ridge for $500,000 on substantially the same terms and conditions that are set
forth herein with respect to the sale of the Class C Shares to Purchaser, and
(ii) 648,927 shares of Class B Common Stock to Funding for $2,000,000.

2. PREFERENCES, LIMITATIONS AND RELATIVE RIGHTS OF THE CLASS C SHARES

         a. Voting. Except as provided in Section 2.i below, the Class C Shares
shall be entitled to vote on all matters voted on at a shareholders' meeting,
with the same voting rights per share as are granted to the Company's Class A
Common Stock and Class B Common Stock. Purchaser acknowledges that 81,279 of the
Class C Shares shall be transferred to a voting trust pursuant to a

                                        2

<PAGE>   3

Voting Trust Agreement among certain of the parties hereto dated the date hereof
(the "Voting Trust Agreement").

         b. Preemptive Rights. Until such time as a Purchaser Approved Offering
(as defined below) has been consummated or Purchaser has otherwise sold all of
its Class C Shares or other equity interests in the Company, Purchaser shall
have preemptive rights with regard to any future issuances of common stock of
the Company (other than an issuance of common stock pursuant to options that are
approved by the holders of the Company's Class B Common Stock) permitting
Purchaser to purchase additional common shares pro rata at the same price and on
the same terms and conditions of such issuance; provided, however, that if the
holders of the Company's Class B Common Stock waive their rights with respect to
a future issuance of common stock, Purchaser shall not have preemptive rights
with respect to that issuance. For purposes of this Agreement, a Purchaser
Approved Offering shall mean the consummation of an underwritten public offering
of common stock of the Company on the New York Stock Exchange, the American
Stock Exchange, or The Nasdaq Stock Market, Inc. pursuant to a registration
statement filed with the Securities and Exchange Commission under the Securities
Act of 1933, as amended (the "1933 Act"), covering the offer and sale of common
stock of the Company to the public at a price resulting in gross proceeds from
such sale to the Company (before deduction of underwriting discounts and
expenses of sale) of not less than $50,000,000.

         c. Right of First Refusal. Except in the event of and after the
consummation of a Purchaser Approved Offering , and except for gifts, charitable
donations or sales in each case representing less than One Percent (1%) of the
Company's outstanding common stock in the aggregate, no shareholder shall be
permitted to dispose of any shares of the Company's common

                                        3

<PAGE>   4

stock unless such shares shall have been offered for sale in writing first to
the Company and then to the other shareholders of the Company pro rata. In the
event a shareholder desires to transfer any common shares, the shareholder
desiring to make such transfer (the "Transferring Shareholder") shall deliver
written notice (the "Offer Notice") to the Company and to all other shareholders
at least sixty (60) days prior to the proposed transfer. The Offer Notice will
disclose in reasonable detail the proposed number of shares to be transferred,
the proposed transferee and the proposed price, terms and conditions of the
transfer.

                  i. Upon receipt of the Offer Notice, the Company shall have
the option (the "Company's Option") for a period of thirty (30) days to purchase
or otherwise acquire all or part of the shares described in the Offer Notice for
an aggregate amount (such aggregate amount being hereinafter referred to as the
"Option Price") equal to the bona fide purchase price to be paid by the proposed
purchaser as described in the Offer Notice (which amount shall be zero if the
proposed transfer would take the form of a gift or other gratuitous transfer).
The Company shall notify in writing all then current shareholders as to whether
it will exercise, partially exercise or not exercise the Company's Option before
the expiration of the Company's Option.

                  ii. In the event that the Company does not elect to fully
exercise the Company's Option within thirty (30) days after receipt of the Offer
Notice, the remaining shareholders shall have the option (each a "Shareholder's
Option") for a period of ten (10) days from the earlier of (i) their receipt of
written notice from the Company of its decision not to exercise or to only
partially exercise the Company's Option, or (ii) the expiration of the Company's
Option (the "Other Shareholder Election Period"), to purchase or otherwise
acquire all or part of the remaining shares which the Company does not choose to
purchase pursuant to the Company's Option, in proportion to their

                                        4

<PAGE>   5

respective ownership of shares which, for purposes of such determination, shall
include without duplication all outstanding options, warrants or other rights
owned by such shareholders that are convertible into shares as of the date of
such notice from the Company (or the expiration of the Company's Option), for an
amount equal to the applicable portion of the Option Price. Each shareholder
shall notify in writing all then current shareholders as to whether such
shareholder will exercise, partially exercise or not exercise the shareholder's
option before the expiration of the Other Shareholder Election Period.

                  iii. For a period of ten (10) days from the earlier of (i) the
receipt by the other shareholders of a written notice from a shareholder that it
does not want to exercise its option or will only partially exercise its option,
or (ii) the expiration of the Other Shareholder Election Period, the other
shareholders shall have the right to purchase or otherwise acquire such
shareholder's portion of the shares described in the Offer Notice in proportion
to their respective ownership of shares (determined as described in Section
2.c.ii. above).

                  iv. If shares of a Transferring Shareholder remain unsold
after compliance with the procedures set forth in this Section 2.c., the Company
shall have the final option for ten (10) days to purchase or otherwise acquire
all of the remaining shares proposed to be transferred for an amount equal to
the applicable portion of the Option Price. If, however, the Company and the
other shareholders do not individually or collectively elect to purchase all of
the shares being offered, the Transferring Shareholder may, within thirty (30)
days after the expiration of the Other Shareholder Election Period (subject to
the provisions of Section 2.c.vi. below), transfer all of the shares specified
in the Offer Notice to the transferee identified in the notice at the price and
terms stated in the Offer Notice. Any shares so transferred thereupon shall
continue to be subject to this Agreement, and the

                                        5

<PAGE>   6

transferee shall have the rights and obligations set forth in this Agreement
hereunder with respect to such shares. If the Transferring Shareholder fails to
consummate such transfer within the thirty-day period after the expiration of
the Other Shareholder Election Period, any transfer of the shares thereafter
shall again be subject to the provisions of this Section 2.c.

                  v. Unless otherwise agreed in writing, signed by the person
against whom such writing is sought to be enforced, the closing of any
acquisition of common shares hereunder pursuant to the Company's Option or a
Shareholder's Option shall take place within forty-five (45) days of an
applicable option's exercise. If any such closing does not take place within
such forty-five day period, then the shares that were to be acquired shall be
offered in accordance with this Section 2.c. as though the applicable option had
not been exercised.

                  vi. Notwithstanding the foregoing provisions of this Section
2.c., the following shall apply in the event of any Involuntary Transfer of
common shares. An "Involuntary Transfer" shall mean any transfer caused by the
death of a shareholder, as well as any transfer, proceeding or action by,
through, as a consequence of, or in which a shareholder shall be deprived or
divested of any right, title or interest in or to any of the common stock of the
Company, including, without limitation, any seizure under levy, attachment or
execution, any transfer in connection with bankruptcy (whether pursuant to a
filing of a voluntary or an involuntary petition under the United States
Bankruptcy Code, or any amendments, modifications, revisions or successors
statutes thereto) or other court proceeding to a debtor-in-possession, trustee
in bankruptcy or receiver or other officer or agency, any transfer to a state or
to a public officer or agency pursuant to any statute pertaining to escheat or
abandoned property, any transfer pursuant to a separation agreement, equitable

                                        6

<PAGE>   7

distribution agreement or community property distribution agreement, or the
entry of a final court order in a divorce proceeding from which there is no
further right of appeal.

                  In the event of any Involuntary Transfer, the Company shall
give written notice to each shareholder upon the occurrence, or prospective
occurrence, of such Involuntary Transfer within fifteen (15) days of the date on
which the Company is notified of the occurrence or prospective occurrence of
such Involuntary Transfer. The foregoing provisions of this Section 2.c. then
shall apply, except (i) the Option Price shall be the value of the Company as
determined by a qualified representative of a nationally recognized investment
banking or accounting firm mutually agreeable to the Company, Purchaser, and the
shareholder who made, or may make, the Involuntary Transfer, multiplied by the
percentage of all equity interests in the Company that is then represented by
the shares that are the subject of the Involuntary Transfer, such independent
appraised value to take into account the earnings and book value of the Company,
and (ii) the appraiser shall deliver written notice of such valuation to the
Company and to all other shareholders promptly following his completion of such
valuation, and such written notice shall be considered the Option Notice for
purposes of this Section 2.c. The cost of the appraisal shall be shared equally
by the Company and the shareholder who made, or may make, the Involuntary
Transfer.

                  At the closing of any purchase by the Company or any
shareholders pursuant to this Section 2.c.vi., the involuntary transferee shall
deliver certificates representing the common shares being purchased, duly
endorsed for transfer and accompanied by all requisite stock transfer taxes, and
such shares shall be conveyed free and clear of any liens, claims, options,
charges, encumbrances or rights of others arising through the action or inaction
of the involuntary transferee, and the

                                        7

<PAGE>   8

involuntary transferee shall so represent and warrant. The involuntary
transferee shall further represent and warrant that he is the beneficial owner
of such shares.

                  In the event the provisions of this Section 2.c.vi. shall be
held to be unenforceable with respect to any particular Involuntary Transfer of
common stock, or if all of the shares subject to the Involuntary Transfer are
not purchased by the Company and/or one or more shareholders, and if the
involuntary transferee subsequently desires to transfer such common stock, the
involuntary transferee shall be deemed to be a "Transferring Shareholder" under
Section 2.c. and shall be bound by the other provisions of this Agreement.

                  vii. Notwithstanding anything to the contrary contained in
this Section 2.c., no shareholder shall transfer any common shares at any time
if such action would constitute a violation of any federal or state securities
laws or a breach of the conditions to any exemption from registration of the
shares under any such laws or a breach of any undertaking or agreement of such
shareholder entered into pursuant to such laws or in connection with obtaining
an exemption thereunder. Each shareholder agrees that any shares purchased or
acquired by such shareholder shall bear appropriate legends restricting the sale
or other transfer of such shares in accordance with applicable federal and state
securities laws, in addition to a legend referring to the restrictions set forth
in this Agreement.

         d.       Rights With Regard to Registration of Purchaser's Common
                  Shares.

                  i. In the event that the Company registers any of its common
stock or other securities under federal and state securities laws for a primary
offering or a secondary offering by the Company or any of the officers or
directors of the Company who are also shareholders (a "Management Shareholder"),

Purchaser shall have piggy-back registration rights to include all common stock
then owned by Purchaser (collectively, the "Purchaser's Common Shares"), in any

                                       8

<PAGE>   9

such offering on a pro rata basis. The Company shall give Purchaser notice of
such proposed registration at least thirty (30) days prior to the filing of a
registration statement. Upon the written request of Purchaser delivered to the
Company within twenty (20) days after the receipt of the notice from the
Company, which request shall state the number of Purchaser's Common Shares that
Purchaser wishes to sell or distribute publicly under the registration statement
proposed to be filed by the Company, the Company shall use its best efforts to
register Purchaser's Common Shares, and to cause such registration to become and
remain effective so long as the Company keeps such registration effective as to
any other common stock of the Company. Purchaser's Common Shares registered
pursuant to this Section 2.d.i. must be purchased and offered for sale by a bona
fide underwriter or underwriters in a public offering on a firm commitment
basis. The Company's managing underwriter shall have the right to limit in whole
or in part the total number of Purchaser's Common Shares to be sold hereunder,
so long as such limitation is applied on a pro rata basis with respect to all
shares proposed or requested to be registered by the Company and all
shareholders. The expenses of any such offering shall be borne by the Company,
except for Purchaser's pro rata share of any underwriter's discount or sales
agent's commission.

                  ii. If, in connection with any registration under this Section
2.d, any of the common shares of Company stock require registration or
qualification under the securities or "blue sky" laws of any state, or the
approval of any state governmental official or authority, the Company shall take
all requisite action and use its best efforts to cause such shares to be duly
registered, qualified or approved as may be required. If any shares meet the
criteria for listing on any exchange on which such stock of the Company is then
listed, the Company shall apply for and use its best efforts to obtain a listing
of all such shares on such exchange.

                                        9

<PAGE>   10

                  iii. Except as provided in Section 2.d.i. above, the Company
shall pay all of the expenses in connection with the registration of any shares
of Company stock, including, without limitation, the costs of preparing,
printing and filing the registration statement in compliance with the 1933 Act,
the fees and expenses of counsel and accountants for the Company, Management
Shareholders and Purchaser for qualifying the offering under the securities or
"blue sky" laws and regulations of the state in which the offering is qualified.

         e.       Sale of the Company.

                  i. At any time after April 4, 2000, and before the
consummation of a Purchaser Approved Offering, if a bona fide offer is made by
any person (other than Purchaser, or any person or entity related to or
affiliated with Purchaser), to purchase all or substantially all of the assets
or shares of stock of the Company, and Funding gives the Company written notice
that it desires such offer to be accepted, the Company and its shareholders
shall either accept the offer and consummate the sale on the terms and
conditions of the offer (in which case, if the transaction is a stock sale or
merger, Purchaser also shall sell all of its equity interests in the Company on
those terms and conditions), or the Company shall acquire all the equity
interests owned by Purchaser and Funding in the Company on the same terms and
conditions as the offer; provided, however, that if such offer is made prior to
April 4, 2002, the Company shall have no such obligation unless the total
consideration of such offer is at least $50,000,000. If at any time Funding
approves the sale of substantially all of the assets or shares of stock of the
Company, then Purchaser shall vote its shares in favor of the transaction so
approved and, if the transaction is a stock sale or merger, shall sell all of
its equity interests in the Company on the terms and conditions so approved.

                                       10

<PAGE>   11

         In determining the total consideration for purposes of the foregoing,
any deferred payment shall be discounted to present value at a discount rate of
eight percent (8%) per annum. If the total consideration set forth in the offer
includes anything other than cash and/or marketable securities (the "Non-Cash
Consideration") then the Company, at its option, may acquire Purchaser's equity
interests for the product of (a) either (i) the Non-Cash Consideration specified
or (ii) cash in the amount of the fair market value of the total consideration
set forth in the offer, multiplied by (b) the percentage of all outstanding
equity interests of the Company that then is owned by Purchaser. Such fair
market value shall be determined pursuant to the terms of the Stock Purchase
Agreements dated April 4, 1997, March 31, 1998 and the date hereof by and among
the Company, Funding and the other stockholders of the Company (the "Funding
Purchase Agreements").

         If the offer contemplates an asset sale, the Company may acquire
Purchaser's equity interests for cash equal to the product of (a) the after-tax
value to the Company of the consideration set forth in the offer multiplied by
(b) the percentage of all outstanding equity interests of the Company that is
then owned by Purchaser. If the Company decides to acquire Purchaser's and
Funding's equity interests, the Company shall acquire Purchaser's and Funding's
equity interests for cash within ninety (90) days from the date of Funding's
written notice.

                  ii. At any time before the consummation of a Purchaser
Approved Offering, if any assets or stock of the Company is sold for any reason,
or if the Company is merged or consolidated, then the following payments (the
"Management Shareholder Payments") to the Management Shareholders in connection
with such sale, merger or consolidation shall be deemed, for purposes of this
Agreement, as part of the total consideration to be paid for the Company so that
Purchaser shall be entitled to receive from the Company, pari passu with the
rights of holders of the

                                       11

<PAGE>   12

Company's Class B Common Stock and all other holders of the Company's Class C
Common Stock to be paid with respect to the Management Shareholder Payments, and
before any distribution to shareholders, a priority distribution equal to the
product of (1) the sum of (a) all payments made to a Management Shareholder in
consideration of any covenant not to compete or consulting agreement, plus (b)
the component of any compensation to a Management Shareholder for employment
services that is in excess of the prevailing industry average compensation, paid
by companies that are similar to the company that will be making the payments to
the Management Shareholder, for the management responsibilities actually to be
performed by the Management Shareholder, as such average compensation is
mutually agreed between the Company, the Management Shareholder and Funding, or
if they cannot agree, then as determined by a current survey of total
compensation conducted by a qualified representative of a nationally recognized
investment banking or accounting firm mutually agreeable to the Company, the
Management Shareholder, and Funding, multiplied by (2) the percentage of all
equity interests in the Company that is then owned by Purchaser.

         The priority distribution due Purchaser under this Paragraph 2.e.ii.
shall be paid on the same schedule as the Management Shareholder Payments are
received by the Management Shareholder. If the Company has insufficient funds to
pay the portion of the priority distribution that is due at the time a
Management Shareholder receives a Management Shareholder Payment, the Management
Shareholders receiving Management Shareholder Payments shall pay Purchaser the
amount of such insufficiency pro rata in accordance with the proportionate

         Any claim for indemnification which is based upon a final judgment,
decree or award of a court of competent jurisdiction requiring the payment of
money by any party to this Agreement or any of its officers, directors or
controlling persons, shall be conclusive as to the amount of such claim,
provided a certified copy of such judgment, decree or award accompanies the
notice relating to such claim and provided further that the party seeking
indemnification shall have complied with Section 14 of this Agreement.

                                       39

<PAGE>   40

         Any claim for indemnification shall be conclusive in all respects
thirty (30) days after receipt by the other party of notice thereof, unless
within such period the indemnifying party shall have sent to the party seeking
indemnification, and the party seeking indemnification shall have received,
notice questioning the propriety of the claim, in which case such claim, unless
settled by agreement of the parties, shall be promptly referred to arbitration
as provided in Section 13. In the event that a party makes a claim for
indemnification, and the indemnifying party contests that claim but the claim is
not settled or referred to arbitration within sixty (60) days after receipt by
the indemnifying party of notice of the claim from the party seeking
indemnification, such claim shall be regarded as conclusive in all respects.

13.      DISPUTE RESOLUTION

         All disputes arising hereunder between the parties shall be referred to
arbitration under the Uniform Arbitration Act as adopted in Delaware, according
to the rules of the American Arbitration Association. Judgment upon the award by
the arbitrator may be entered in any court having jurisdiction thereof. As part
of such award, the arbitrator shall be promptly paid by the party that initiates
the proceeding, but the portion of each such fee and expenses which represents
the same percentage thereof as the percentage of the amount of the claim
represented by the amount awarded shall be added to the amount of the award and
shall be borne by the indemnifying party. Any award shall be a conclusive
determination of the matter and shall be binding upon Purchaser and the Company
and shall not be contested by either of them. Arbitration proceedings shall be
held in the city of Dover, Delaware unless the parties agree upon another
location. In any such action the prevailing party, in the judgment of the
arbitrator, shall be entitled to an award of its costs and attorneys' fees
incurred in the action.

<PAGE>   41

14.      THIRD PARTY CLAIMS

         In the event that any legal proceeding shall be instituted, or any
claim or demand shall be asserted, by any third party in respect of which
indemnity may be sought by Purchaser or the Company pursuant to the provisions
of this Agreement, the party seeking indemnification, with reasonable promptness
after obtaining knowledge of such proceeding, claim or demand shall give written
notice thereof to the other party, who shall then have the right, at its option
and expense, to be represented by counsel of its choice in connection with such
matter, which counsel shall be reasonably satisfactory to the party seeking
indemnification, and to defend against, negotiate, settle or otherwise deal with
any such proceeding, claim or demand; provided, however, that without the prior
written consent of the party seeking indemnification, which consent shall not be
unreasonably withheld, the indemnifying party shall not consent to the entry of
any judgment in or agree to any settlement of any such matters; and provided
further that the party seeking indemnification may retain counsel, at its own
expense, to represent it and participate in connection with any such proceeding
or claim or demand. Failure by the indemnifying party to notify the party
seeking indemnification of the indemnifying party's election to defend any
proceeding, claim or demand with respect to which indemnity is sought within
thirty (30) days after notice thereof shall have been given by the party seeking
indemnification shall be deemed a waiver by the indemnifying party of its right
to defend against such matter. If the indemnifying party assumes defense of any
such proceeding, claim or demand, it shall take or cause to be taken all steps
necessary in connection with such defense, and the party seeking indemnification
shall in all events be entitled to indemnity with respect to such matter, as
provided in this Agreement. In the event that the indemnifying party does not
elect to defend any proceeding, claim or demand with respect to which indemnity
is sought, the party seeking

                                       41

<PAGE>   42

indemnification may defend against, settle or otherwise deal with any such
proceeding, claim or demand in such matter as it may in its good faith
discretion deem appropriate and the indemnifying party shall be liable for
indemnification with respect to such matter, including without limitation the
reasonable costs of such defense, as provided in this Agreement. In the event of
any proceeding, claim or demand by a third party with respect to which a claim
for indemnification is made hereunder, the parties hereto agree that they will
cooperate fully with each other in connection with the defense or settlement of
such matter.

15.      MISCELLANEOUS.

         a. Counterparts. This Agreement may be executed simultaneously in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

         b. Waiver of Compliance. Any failure of Purchaser or of the Company to
comply with any obligation, agreement or condition contained herein may be
expressly waived in writing by the Company or Purchaser, respectively, but such
waiver or failure to insist upon strict compliance with such obligation,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure. No waiver shall be binding unless
executed in writing by the party or parties making such waiver.

         c. Assignment; Binding on Successors. This Agreement may not be
assigned by any party hereto without the written consent of the other parties
hereto, provided, however, that Purchaser may assign any or all of its rights
and obligations hereunder to any person or entity to whom Purchaser transfers

sole representative of any such transferee in dealing with all matters
