ITEM 5.  OTHER EVENTS.

         As previously announced, Intelect Communications, Inc. (the "Company")
closed the issuance of 5,000,000 investment units to The Coastal Corporation
Second Pension Trust ("Coastal") in exchange for a $5 million reduction in
Intelect's obligations under its $12 million Revolving Credit Agreement with
Coastal. Such amount will be available for borrowing by the Company subject to
the terms of the credit agreement. Each"investment unit" consists of one share
of restricted Intelect common stock and one restricted warrant. The warrants,
which are not immediately exercisable, have a term of three years, a strike
price of $0.75 per share and may not be exercised until at least six months
after issuance and after the common stock of the Company has a daily closing
price of $1.20 or more for five consecutive days. In addition, pursuant to the
transaction, the Company agreed that the exercise price of Coastal's currently
outstanding warrants to purchase 450,000 shares and 1,067,308 shares of common
stock of the Company would be re-set to $0.75 per share. Coastal has the right
to designate a person to fill the current vacancy on the Company's Board of

                                    ARTICLE I
                              EXERCISE OF WARRANTS

         Section I.1 Method of Exercise. The Warrants represented hereby may be
exercised by the Holder hereof, in whole or in part, at any time and from time
to time on or after June 15, 2000 until 5:00 p.m., Houston, Texas time, on
December 16, 2002 (the "Exercise Date").

                  (a)      To exercise the Warrants, the Holder hereof shall
deliver to the Company, at the Warrant Office designated in Section 2.1 hereof:

                           (i)      a written notice in the form of the
Subscription Notice attached as an exhibit hereto, stating therein the election
of such holder to exercise the Warrants in the manner provided in the
Subscription Notice;

                           (ii)     payment in full of the Exercise Price (A) in
cash or immediately available funds for all Warrant Shares purchased hereunder,
or (B) if the Company and the Holder mutually elect, through a "cashless" or
"net-issue" exercise of each such Warrant ("Cashless Exercise"); the Holder

                                      -2-
<PAGE>   3


Price for each such Warrant, and the denominator of which shall be the Market
Price; the Subscription Notice shall set forth the calculation upon which the
Cashless Exercise is based, or (C) a combination of (A) and (B) above; and

                           (iii)    this Warrant.

                  (b)      The Warrants shall be deemed to be exercised on the
date of receipt by the Company of the Subscription Notice, accompanied by
payment for the Warrant Shares and surrender of this Warrant, as aforesaid, and
such date is referred to herein as the "Exercise Date". Upon such exercise, the
Company shall, as promptly as practicable and in any event within ten (10)
business days, issue and deliver to such holder a certificate or certificates
for the full number of the Warrant Shares purchased by such holder hereunder,
and shall, unless the Warrants have expired, deliver to the Holder hereof a new
Warrant representing the number of Warrants, if any, that shall not have been
exercised, in all other respects identical to this Warrant. As permitted by
applicable law, the person in whose name the certificates for Common Stock are
to be issued shall be deemed to have become a holder of record of such Common
Stock on the Exercise Date and shall be entitled to all of the benefits of such
holder on the Exercise Date, including without limitation the right to receive
dividends and other distributions for which the record date falls on or after
the Exercise Date and to exercise voting rights.

         Section I.2 Reservation of Shares. The Company shall reserve at all
times so long as the Warrants remain outstanding, free from preemptive rights,
out of its treasury Common Stock or its authorized but unissued shares of Common
Stock, or both, solely for the purpose of effecting the exercise of the
Warrants, a sufficient number of shares of Common Stock to provide for the
exercise of the Warrants, provided that no shares of Common Stock shall be
required to be reserved for issuance upon exercise of this Warrant until the
Restrictions on Exercise have been met, provided further, that if insufficient
shares have been authorized at the time of Coastal's notice of timely exercise
of the Warrants following satisfaction of the Restrictions on Exercise, Coastal
shall be entitled to damages as follows: The amount of damages shall be
calculated as the average closing Market Price for the Common Stock for the ten
(10) Trading Days preceding the deemed date of exercise in accordance with
Section 1.1(b), less the Exercise Price of such Warrant, multiplied by the
number of Warrants sought to be exercised. The Company shall pay the damages
within ten (10) business days and shall, unless the Warrants have expired,
deliver to the Holder hereof a new Warrant representing the number of Warrants,
if any, that shall not have been exercised, in all other respects identical to
this Warrant. The Warrants for which damages are paid in accordance with this
Section shall be deemed exercised.

         Section I.3 Expenses and Taxes. The Company shall pay all expenses, and
taxes (including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.

         Section I.4 Valid Issuance. All shares of Common Stock that may be
issued upon exercise of the Warrants will, upon issuance by the Company, be duly
and validly issued, fully paid and nonassessable and free from all taxes, liens
and charges with respect to the issuance thereof and, without limiting the
generality of the foregoing, the Company shall take no action or fail to take
any action which will cause a contrary result (including, without limitation,
any action that would cause the Exercise Price to be less than the par value, if
any, of the Common Stock).

         Section I.5 Purchase Agreement. The Warrants represented hereby are
part of a duly authorized issuance and sale of Warrants to purchase Common Stock
issued and sold pursuant to the Subscription Agreement between Holder and
Company of even date herewith.

         Section I.6 Acknowledgment of Rights. At the time of the exercise of
the Warrants in accordance with the terms hereof and upon the written request of
the Holder hereof, the Company will acknowledge in writing its continuing
obligation to afford to such holder any rights (including, without limitation,
any right to registration of the Warrant Shares) to which such holder shall
continue to be entitled after such exercise in accordance with the provisions of
this Warrant; provided, however, that if the Holder hereof shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

         Section I.7 No Fractional Shares. The Company shall not be required to
issue fractional shares of Common Stock on the exercise of this Warrant. If more
than one Warrant shall be presented for exercise at the same


                                      -3-
<PAGE>   4


time by the same holder, the number of full shares of Common Stock which shall
be issuable upon such exercise shall be computed on the basis of the aggregate
number of whole shares of Common Stock purchasable on exercise of the Warrants
so presented. If any fraction of a share of Common Stock would, except for the
provisions of this Section 1.7, be issuable on the exercise of this Warrant, the
Company shall pay an amount in cash calculated by it to be equal to the Market
Price of one share of Common Stock at the time of such exercise multiplied by
such fraction computed to the nearest whole cent.

                                   ARTICLE II
                                    TRANSFER

         Section II.1 Warrant Office. The Company shall maintain an office for
certain purposes specified herein (the "Warrant Office"), which office shall
initially be the Company's offices at 1100 Executive Drive, Richardson, Texas
75081 and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the Holder hereof. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

         Section II.2 Ownership of Warrants. The Company may deem and treat the
person in whose name the Warrants are registered as the Holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Article II. Notwithstanding the foregoing, the Warrants
represented hereby, if properly assigned in compliance with this Article II, may
be exercised by an assignee for the purchase of Warrant Shares without having a
new Warrant issued.

         Section II.3 Restrictions on Transfer of Warrants.

                  (a)      The Company agrees to maintain at the Warrant Office
books for the registration and transfer of the Warrants. Subject to the
restrictions on transfer of the Warrants in this Section 2.3, the Company, from
time to time, shall register the transfer of the Warrants in such books upon
surrender of this Warrant at the Warrant Office properly endorsed or accompanied
by appropriate instruments of transfer and written instructions for transfer
satisfactory to the Company. Upon any such transfer and upon payment by the
Holder or its transferee of any applicable transfer taxes, new Warrants shall be
issued to the transferee and the transferor (as their respective interests may
appear) and the surrendered Warrants shall be canceled by the Company. The
Company shall pay all taxes (other than securities transfer taxes or income
taxes) and all other expenses and charges payable in connection with the
transfer of the Warrants pursuant to this Section 2.3.

                  (b)      The Holder of the Warrants agrees that it will
neither (i) transfer the Warrants prior to delivery to the Company of written
notice of such transfer, nor (ii) transfer such Warrant Shares prior to delivery
to the Company of written notice of such transfer, or until registration of such
Warrant Shares under the Securities Act and any applicable state securities or
Blue Sky laws has become effective.

         Section II.4 Compliance with Securities Laws. Subject to the terms of
the Registration Rights Agreement between the Holder and the Company dated as of
the date hereof and notwithstanding any other provisions contained in this
Warrant, the Holder hereof understands and agrees that the following
restrictions and limitations shall be applicable to all Warrant Shares and to
all resales or other transfers thereof pursuant to the Securities Act:

                  (a)      The Holder hereof agrees that the neither this
Warrant nor the Warrant Shares shall be sold or otherwise transferred unless
this Warrant and/or the Warrant Shares are registered under the Securities Act
and applicable state securities or Blue Sky laws or are exempt therefrom.

                  (b)      A legend in substantially the following form will be
placed on the certificate(s) evidencing the Warrant Shares:

                           "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                  NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE


                                      -4-
<PAGE>   5


                  "SECURITIES ACT"), OR ANY OTHER APPLICABLE SECURITIES LAW AND,
                  ACCORDINGLY, THE SECURITIES REPRESENTED BY THIS CERTIFICATE
                  MAY NOT BE RESOLD, PLEDGED, OR OTHERWISE TRANSFERRED, EXCEPT
                  PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER, OR IN A
                  TRANSACTION EXEMPT FROM REGISTRATION UNDER, THE SECURITIES ACT
                  AND IN ACCORDANCE WITH ANY OTHER APPLICABLE SECURITIES LAWS."

                  (c)      Stop transfer instructions will be imposed with
respect to the Warrant Shares so as to restrict resale or other transfer
thereof, subject to this Section 2.4.

                  (d)      The Holder understands that it must bear the economic
risk of the investment for an indefinite period of time because the Warrant
Shares have not been registered under the Securities Act and therefor cannot be
sold unless they are subsequently registered under the Securities Act or an
exemption from such registration is available. The Holder acknowledges that the
Holder or the Holder's representative is familiar with the condition, financial
and otherwise, of the Company. The Holder or the Holder's representative has
such knowledge and experience in financial and business matters that the Holder
or the Holder's representative is able to weigh the information so received and
to evaluate the merits and risks of the Holder's investment in the Warrant
Shares.

                                   ARTICLE III
                                  ANTI-DILUTION

         Section III.1 Anti-Dilution Provisions. The Exercise Price shall be
subject to adjustment from time to time as hereinafter provided. Upon each
adjustment of the Exercise Price, the Holder of this Warrant shall thereafter be
entitled to purchase, at the Exercise Price resulting from such adjustment, the
number of shares of Common Stock obtained by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

         Section III.2 Adjustment of Exercise Price Upon Issuance of Common
Stock.

                  (a)      (i)      If and whenever after the date hereof the
         Company shall issue or sell any Common Stock for no consideration or
         for a consideration per share less than the Exercise Price, then,
         forthwith upon such issue or sale, the Exercise Price shall be reduced
         (but not increased, except as otherwise specifically provided in
         Section 3.2 hereof), to the price (calculated to the nearest one-ten
         thousandth of a cent) determined by dividing (x) an amount equal to the
         sum of (i) the aggregate number of shares of Common Stock Outstanding
         immediately prior to such issue or sale multiplied by the consideration
         received by the Company upon such issuance or sale on a per share basis
         plus (ii) the consideration received by the Company upon such issue or
         sale by (y) the aggregate number of shares of Common Stock Outstanding
         immediately after such issue or sale.

                           (ii)     Notwithstanding the provisions of this
         Section 3.2, no adjustment shall be made in the Exercise Price in the
         event that the Company issues, in one or more transactions, (A) Common
         Stock or Convertible Securities upon exercise of any options issued to
         officers, directors or employees of the Company pursuant to a stock
         option plan or an employment, severance or consulting agreement as now
         or hereafter in effect, in each case approved by the Board of Directors
         (provided that the aggregate number of shares of Common Stock which may
         be issuable, including options issued prior to the date hereof, under
         all such employee plans and agreements shall at no time exceed the
         number of such shares of Common Stock that are issuable under currently
         effective employee plans and agreements); (B) Common Stock upon
         exercise of the Warrants or any other Warrant issued pursuant to the
         terms of the Agreement or otherwise issued to the Holder; (C) Common
         Stock upon exercise of any stock purchase Warrant or option (other than
         the options referred to in clause "(A)" above) or other convertible
         security outstanding on the date hereof; (D) Common Stock upon
         conversion of the Note; or (E) Common Stock issued as consideration in
         acquisitions. In addition, for purposes of calculating any adjustment
         of the Exercise Price as provided in this Section 3.2, all of the
         shares of Common Stock issuable pursuant to any of the foregoing shall
         be assumed to be Outstanding prior to the event causing such adjustment
         to be made.

         (b)      For purposes of this Section 3.2, the following Sections
3.2(b)(i) to 3.2(b)(v) inclusive, shall be applicable:

                  (i)      Issuance of Rights or Options. In case at any time
         after the date hereof the Company shall in any manner grant (whether
         directly or by assumption in a merger or otherwise) any rights to
         subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or securities convertible into or
         exchangeable for Common Stock (such convertible or exchangeable stock
         or securities being herein called "Convertible Securities"), whether or
         not such rights or options or the right to convert or exchange any such
         Convertible Securities are immediately exercisable, and the price per
         share for which shares of Common Stock are issuable upon the exercise
         of such rights or options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (A) the total amount, if
         any, received or receivable by the Company as consideration for the
         granting of such rights or options, plus the minimum aggregate amount
         of additional consideration, if any, payable to the Company upon the
         exercise of such rights or options, or plus, in the case of such rights
         or options that relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (B) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon the
         conversion or exchange of all such Convertible Securities issuable upon
         the exercise of such rights or options) shall be less than the Exercise
         Price in effect as of the date of granting such rights or options, then
         the total maximum number of shares of Common Stock issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         all such Convertible Securities issuable upon the exercise of such
         rights or options shall be deemed to be outstanding as of the date of
         the granting of such rights or options and to have been issued for such
         price per share, with the effect on the Exercise Price specified in
         Section 3.2(a) hereof. Except as provided in Section 3.2(b) hereof, no
         further adjustment of the Exercise Price shall be made upon the actual
         issuance of such Common Stock or of such Convertible Securities upon
         exercise of such rights or options or upon the actual issuance of such
         Common Stock upon conversion or exchange of such Convertible
         Securities.

                           (ii)     Change in Option Price or Conversion Rate.
         Upon the happening of any of the following events, namely, if the
         purchase price provided for in any right or option referred to in
         Section 3.2(b), the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         Section 3.2(b), or the rate at which any Convertible Securities
         referred to in Section 3.2(b), are convertible into or exchangeable for
         Common Stock shall change (other than under or by reason of provisions
         designed to protect against dilution), the Exercise Price then in
         effect hereunder shall forthwith be readjusted (increased or decreased,
         as the case may be) to the Exercise Price that would have been in
         effect at such time had such rights, options or Convertible Securities
         still outstanding provided for such changed purchase price, additional
         consideration or conversion rate, as the case may be, at the time
         initially granted, issued or sold. On the expiration of any such option
         or right referred to in Section 3.2(b), or on the termination of any
         such right to convert or exchange any such Convertible Securities
         referred to in Section 3.2(b), the Exercise Price then in effect
         hereunder shall forthwith be readjusted (increased or decreased, as the
         case may be) to the Exercise Price that would have been in effect at
         the time of such expiration or termination had such right, option or
         Convertible Securities, to the extent outstanding immediately prior to
         such expiration or termination, never been granted, issued or sold, and
         the Common Stock issuable thereunder shall no longer be deemed to be
         Outstanding. If the purchase price provided for in Section 3.2(b) or
         the rate at which any Convertible Securities referred to in Section
         3.2(b) reduced at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible
         Securities, the Exercise Price then in effect hereunder shall, if not
         already adjusted, forthwith be adjusted to such amount as would have
         obtained had such right, option or Convertible Securities never been
         issued as to such Common Stock and had adjustments been made upon the
         issuance of the Common Stock delivered as aforesaid, but only if as a
         result of such adjustment the Exercise Price then in effect hereunder
         is thereby reduced.

                          (iii)    Consideration for Stock. In case at any time
         Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for cash, the consideration therefor shall be deemed to
         be the amount received by the Company therefor. In


                                      -6-
<PAGE>   7


         case at any time any Common Stock, Convertible Securities or any rights
         or options to purchase any such Common Stock or Convertible Securities
         shall be issued or sold for consideration other than cash, the amount
         of the consideration other than cash received by the Company shall be
         deemed to be the fair value of such consideration, as determined
         reasonably and in good faith by the Board of Directors of the Company.
         In case at any time any Common Stock, Convertible Securities or any
         rights or options to purchase any Common Stock or Convertible
         Securities shall be issued in connection with any merger or
         consolidation in which the Company is the surviving corporation, the
         amount of consideration received therefor shall be deemed to be the
         fair value, as determined reasonably and in good faith by the Board of
         Directors of the Company, of such portion of the assets and business of
         the nonsurviving corporation as such Board of Directors may determine
         to be attributable to such Common Stock, Convertible Securities, rights
         or options as the case may be. In case at any time any rights or
         options to purchase any shares of Common Stock or Convertible
         Securities shall be issued in connection with the issuance and sale of
         other securities of the Company, together consisting of one integral
         transaction in which no consideration is allocated to such rights or
         options by the parties, such rights or options shall be deemed to have
         been issued with consideration.

                           (iv)     Record Date. In the case the Company shall
         take a record of the holders of its Common Stock for the purpose of
         entitling them (i) to receive a dividend or other distribution payable
         in Common Stock or Convertible Securities, or (ii) to subscribe for or
         purchase Common Stock or Convertible Securities, then such record date
         shall be deemed to be the date of the issuance or sale of the Common
         Stock or Convertible Securities deemed to have been issued or sold as a
         result of the declaration of such dividend or the making of such other
         distribution or the date of the granting of such right of subscription
         or purchase, as the case may be.

                           (v)      Treasury Shares. The number of shares of
         Common Stock Outstanding at any given time shall not include shares
         owned directly by the Company in treasury, and the disposition of any
         such shares shall be considered an issuance or sale of Common Stock for
         the purpose of this Section 3.2.

         Section III.3 Stock Dividends. In case the Company shall declare a
dividend or make any other distribution upon any shares of the Company, payable
in Common Stock or Convertible Securities, any Common Stock or Convertible
Securities, as the case may be, issuable in payment of such dividend or
distribution shall be deemed to have been issued or sold without consideration.

         Section III.4 Stock Splits and Reverse Splits. In the event that the
Company shall at any time subdivide its Outstanding shares of Common Stock into
a greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Warrant
Shares purchasable pursuant to this Warrant immediately prior to such
subdivision shall be proportionately increased, and conversely, in the event
that the Outstanding shares of Common Stock shall at any time be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
purchasable upon the exercise of this Warrant immediately prior to such
combination shall be proportionately reduced. Except as provided in this Section
3.4, no adjustment in the Exercise Price and no change in the number of Warrant
Shares purchasable shall be made under this Article III as a result of or by
reason of any such subdivision or combination.

         Section III.5 Reorganizations and Asset Sales. If any capital
reorganization or reclassification of the capital stock of the Company, or any
consolidation, merger or share exchange of the Company with another person, or
the sale, transfer or other disposition of all or substantially all of its
assets to another person shall be effected in such a way that a holder of Common
Stock of the Company shall be entitled to receive capital stock, securities or
assets with respect to or in exchange for their shares, then the following
provisions shall apply:

                  (a)      As a condition of such reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer or other
disposition (except as otherwise provided below in this Section 3.5), lawful and
adequate provisions shall be made whereby the holder of Warrants shall
thereafter have the right to purchase and receive upon the terms and conditions
specified in this Warrant and in lieu of the Warrant Shares immediately
theretofore receivable upon the exercise of the rights represented hereby, such
shares of capital stock, securities or assets as may be issued or payable with
respect to or in exchange for a number of Outstanding shares of such Common
Stock equal to the number of Warrant Shares immediately theretofore so
receivable had such reorganization, reclassification,


                                      -7-
<PAGE>   8


consolidation, merger, share exchange or sale not taken place, and in any such
case appropriate provision reasonably satisfactory to such holder shall be made
with respect to the rights and interests of such holder to the end that the
provisions hereof (including, without limitation, provisions for adjustments of
the Exercise Price and of the number of Warrant Shares receivable upon the
exercise) shall thereafter be applicable, as nearly as possible, in relation to
any shares of capital stock, securities or assets thereafter deliverable upon
the exercise of Warrants.

                  (b)      In the event of a merger, share exchange or
consolidation of the Company with or into another person as a result of which a
number of shares of Common Stock or its equivalent of the successor person
greater or lesser than the number of shares of Common Stock Outstanding
immediately prior to such merger, share exchange or consolidation are issuable
to holders of Common Stock, then the Exercise Price in effect immediately prior
to such merger, share exchange or consolidation shall be adjusted in the same
manner as though there were a subdivision or combination of the Outstanding
shares of Common Stock.

                  (c)      The Company shall not effect any such consolidation,
merger, share exchange, sale, transfer or other disposition unless prior to or
simultaneously with the consummation thereof the successor person (if other than
the Company) resulting from such consolidation, share exchange or merger or the
person purchasing or otherwise acquiring such assets shall have assumed by
written instrument executed and mailed or delivered to the Holder hereof at the
last address of such holder appearing on the books of the Company the obligation
to deliver to such holder such shares of capital stock, securities or assets as,
in accordance with the foregoing provisions, such holder may be entitled to
receive, and all other liabilities and obligations of the Company hereunder.
Upon written request by the Holder hereof, such successor person will issue a
new Warrant revised to reflect the modifications in this Warrant effected
pursuant to this Section 3.5.

                  (d)      If a purchase, tender or exchange offer is made to
and accepted by the holders of 50% or more of the Outstanding shares of Common
Stock, the Company shall not effect any consolidation, merger, share exchange or
sale, transfer or other disposition of all or substantially all of the Company's
assets with the person having made such offer or with any affiliate of such
person, unless prior to the consummation of such consolidation, merger, share
exchange, sale, transfer or other disposition the Holder hereof shall have been
given a reasonable opportunity to then elect to receive upon the exercise of the
Warrants either the capital stock, securities or assets then issuable with
respect to the Common Stock or the capital stock, securities or assets, or the
equivalent, issued to previous holders of the Common Stock in accordance with
such offer.

         Section III.6 Adjustment for Asset Distribution. If the Company
declares a dividend or other distribution payable to all holders of shares of
Common Stock in evidences of indebtedness of the Company or other assets of the
Company (including, cash (other than regular cash dividends declared by the
Board of Directors), capital stock (other than Common Stock, Convertible
Securities or options or rights thereto) or other property), the Exercise Price
in effect immediately prior to such declaration of such dividend or other
distribution shall be reduced by an amount equal to the amount of such dividend
or distribution payable per share of Common Stock, in the case of a cash
dividend or distribution, or by the fair value of such dividend or distribution
per share of Common Stock (as reasonably determined in good faith by the Board
of Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for purpose
of such dividend or distribution or, if a record is not taken, the date as of
which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         Section III.7 De Minimis Adjustments. No adjustment in the number of
shares of Common Stock purchasable hereunder shall be required unless such
adjustment would require an increase or decrease of at least one share of Common
Stock purchasable upon an exercise of each Warrant and no adjustment in the
Exercise Price shall be required unless such adjustment would require an
increase or decrease of at least $0.01 in the Exercise Price; provided, however,
that any adjustments which by reason of this Section 3.7 are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations shall be made to the nearest full share or nearest
one-hundredth of a dollar, as applicable.

         Section III.8 Notice of Adjustment. Whenever the Exercise Price or the
number of Warrant Shares issuable upon the exercise of the Warrants shall be
adjusted as herein provided, or the rights of the Holder hereof shall change by
reason of other events specified herein, the Company shall compute the adjusted
Exercise Price and the adjusted number of Warrant Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate


                                      -8-
<PAGE>   9


setting forth the adjusted Exercise Price and the adjusted number of Warrant
Shares issuable upon the exercise of the Warrants or specifying the other shares
of stock, securities or assets receivable as a result of such change in rights,
and showing in reasonable detail the facts and calculations upon which such
adjustments or other changes are based. The Company shall cause to be mailed to
the Holder hereof copies of such Officer's Certificate together with a notice
stating that the Exercise Price and the number of Warrant Shares purchasable
upon exercise of the Warrants have been adjusted and setting forth the adjusted
Exercise Price and the adjusted number of Warrant Shares purchasable upon the
exercise of the Warrants.

         Section III.9 Notifications to Holders. In case at any time the Company
proposes:

                  (a)      to declare any dividend upon its Common Stock payable
in capital stock or make any special dividend or other distribution (other than
cash dividends) to the holders of its Common Stock;

                  (b)      to offer for subscription pro rata to all of the
holders of its Common Stock any additional shares of capital stock of any class
or other rights;

                  (c)      to effect any capital reorganization, or
reclassification of the capital stock of the Company, or consolidation, merger
or share exchange of the Company with another person, or sale, transfer or other
disposition of all or substantially all of its assets; or

                  (d)      to effect a voluntary or involuntary dissolution,
liquidation or winding up of the Company, then, in any one or more of such
cases, the Company shall give the Holder hereof (a) at least ten (10) days' (but
not more than ninety (90) days') prior written notice of the date of which the
books of the Company shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of such issuance, reorganization, reclassification, consolidation, merger, share
exchange, sale, transfer, disposition, dissolution, liquidation or winding up,
and (b) in the case of any such issuance, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, at least ten (10) days' (but not more than ninety
(90) days') prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause "(a)" shall also specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto, and such notice in
accordance with the foregoing clause "(b)" shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock, as
the case may be, for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, share exchange, sale,
transfer, disposition, dissolution, liquidation or winding up, as the case may
be.

         Section III.10 Company to Prevent Dilution. If any event or condition
occurs as to which other provisions of this Article III are not strictly
applicable or if strictly applicable would not fairly protect the exercise or
purchase rights of the Warrants evidenced hereby in accordance with the
essential intent and principles of such provisions, or that might materially and
adversely affect the exercise or purchase rights of the Holder hereof under any
provisions of this Warrant, then the Company shall make such adjustments in the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such exercise and purchase rights as aforesaid, and
any adjustments necessary with respect to the Exercise Price and the number of
Warrant Shares purchasable hereunder so as to preserve the rights of the Holder
hereunder. In no event shall any such adjustment have the effect of increasing
the Exercise Price as otherwise determined pursuant to this Article III except
in the event of a combination of shares of the type contemplated in Section 3.4
hereof, and then in no event to an amount greater than the Exercise Price as
adjusted pursuant to Section 3.4 hereof.

to vote, consent, receive dividends or receive notices (other than as herein
expressly provided) in respect of meetings of stockholders for the election of
directors of the Company or any other matter whatsoever as a stockholder of the
Company. No provision hereof, in the absence of affirmative action by the Holder
hereof to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder hereof, shall give rise to any liability of
such holder for the purchase price of any shares of Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

         Section IV.9 Exchange, Loss, Destruction, etc. of Warrant. Upon receipt

destruction upon delivery of a bond of indemnity or such other security in such
form and amount as shall be reasonably satisfactory to the Company, or in the
event of such mutilation upon surrender and cancellation of this Warrant, the

stolen, destroyed or mutilated Warrant. Any Warrant issued under the provisions
of this Section 4.8 in lieu of any Warrant alleged to be lost, destroyed or
stolen, or in lieu of any mutilated Warrant, shall constitute an original
contractual obligation on the part of the Company. This Warrant shall be
promptly canceled by the Company upon the surrender hereof in connection with
any exchange or replacement. The Company shall pay all taxes (other than
securities transfer taxes or income taxes) and all other expenses and charges
payable in connection with the preparation, execution and delivery of Warrants
pursuant to this Section 4.8.

to such registration rights under the Securities Act and under applicable state
securities laws as are specified in the Registration Rights Agreement.

         Section IV.11 Headings. The Article and Section and other headings
herein are for convenience only and are not a part of this Warrant and shall not
affect the interpretation thereof.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be issued as
of December 17, 1999.

                                    ARTICLE I
                              EXERCISE OF WARRANTS

         Section I.1 Method of Exercise. The Warrants represented hereby may be
exercised by the Holder hereof, in whole or in part, at any time and from time
to time on or after the date hereof until 5:00 p.m., Houston, Texas time, on
August 26, 2002 (the "Exercise Date"). To exercise the Warrants, the Holder
hereof shall deliver to the Company, at the Warrant Office designated in Section
2.1 hereof, (i) a written notice in the form of the Subscription Notice attached
as an exhibit hereto, stating therein the election of such holder to exercise
the Warrants in the manner provided in the Subscription Notice; (ii) payment in
full of the Exercise Price (A) in cash or immediately available funds for all
Warrant Shares purchased hereunder, or (B) if the Company and the Holder
mutually elect, through a "cashless" or "net-issue" exercise of each such
Warrant ("Cashless Exercise"); the Holder shall exchange each Warrant subject to
a Cashless Exercise for that number of Warrant Shares determined by multiplying
the number of Warrant Shares issuable hereunder by a fraction, the numerator of
which shall be the difference between (x) the Market Price and (y) the Exercise
Price for each such Warrant, and the denominator of which shall be the Market
Price; the Subscription Notice shall set forth the calculation upon which the
Cashless Exercise is based, or (C) a combination of (A) and (B) above; and (iii)
this Warrant. The Warrants shall be deemed to be exercised on the date of
receipt by the Company of the Subscription Notice, accompanied by payment for
the Warrant Shares and surrender of this Warrant, as aforesaid, and such date is
referred to herein as the "Exercise Date". Upon such exercise, the Company
shall, as promptly as practicable and in any event within ten (10) business
days, issue and deliver to such holder a certificate or certificates for the
full number of the Warrant Shares purchased by such holder hereunder, and shall,
unless the Warrants have expired, deliver to the Holder hereof a new Warrant
representing the number of Warrants, if any, that shall not have been exercised,
in all other respects identical to this Warrant. As permitted by applicable law,
the person in whose name the certificates for Common Stock are to be issued
shall be deemed to have become a holder of record of such Common Stock on the
Exercise Date and shall be entitled to all of the benefits of such holder on the
Exercise Date, including without limitation the right to receive dividends and
other distributions for which the record date falls on or after the Exercise
Date and to exercise voting rights.

         Section I.2 Expenses and Taxes. The Company shall pay all expenses, and
taxes (including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.


                                      -2-
<PAGE>   3


         Section I.3 Reservation of Shares. The Company shall reserve at all
times so long as the Warrants remain outstanding, free from preemptive rights,
out of its treasury Common Stock or its authorized but unissued shares of Common
Stock, or both, solely for the purpose of effecting the exercise of the
Warrants, a sufficient number of shares of Common Stock to provide for the
exercise of the Warrants.

         Section I.4 Valid Issuance. All shares of Common Stock that may be
issued upon exercise of the Warrants will, upon issuance by the Company, be duly
and validly issued, fully paid and nonassessable and free from all taxes, liens
and charges with respect to the issuance thereof and, without limiting the
generality of the foregoing, the Company shall take no action or fail to take
any action which will cause a contrary result (including, without limitation,
any action that would cause the Exercise Price to be less than the par value, if
any, of the Common Stock).

         Section I.5 Purchase Agreement. The Warrants represented hereby are
part of a duly authorized issuance and sale of Warrants to purchase Common Stock
issued and sold pursuant to the Loan Agreement between Holder and Company of
even date herewith.

         Section I.6 Acknowledgment of Rights. At the time of the exercise of
the Warrants in accordance with the terms hereof and upon the written request of
the Holder hereof, the Company will acknowledge in writing its continuing
obligation to afford to such holder any rights (including, without limitation,
any right to registration of the Warrant Shares) to which such holder shall
continue to be entitled after such exercise in accordance with the provisions of
this Warrant; provided, however, that if the Holder hereof shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

         Section I.7 No Fractional Shares. The Company shall not be required to
issue fractional shares of Common Stock on the exercise of this Warrant. If more
than one Warrant shall be presented for exercise at the same time by the same
holder, the number of full shares of Common Stock which shall be issuable upon
such exercise shall be computed on the basis of the aggregate number of whole
shares of Common Stock purchasable on exercise of the Warrants so presented. If
any fraction of a share of Common Stock would, except for the provisions of this
Section 1.7, be issuable on the exercise of this Warrant, the Company shall pay
an amount in cash calculated by it to be equal to the Market Price of one share
of Common Stock at the time of such exercise multiplied by such fraction
computed to the nearest whole cent.

                                   ARTICLE II
                                    TRANSFER

         Section II.1 Warrant Office. The Company shall maintain an office for
certain purposes specified herein (the "Warrant Office"), which office shall
initially be the Company's offices at 1100 Executive Drive, Richardson, Texas
75081 and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the Holder hereof. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

         Section II.2 Ownership of Warrants. The Company may deem and treat the
person in whose name the Warrants are registered as the Holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Article II. Notwithstanding the foregoing, the Warrants
represented hereby, if properly assigned in compliance with this Article II, may
be exercised by an assignee for the purchase of Warrant Shares without having a
new Warrant issued.

         Section  II.3     Restrictions on Transfer of Warrants.

                  (a) The Company agrees to maintain at the Warrant Office books
for the registration and transfer of the Warrants. Subject to the restrictions
on transfer of the Warrants in this Section 2.3, the Company, from time to time,
shall register the transfer of the Warrants in such books upon surrender of this
Warrant at the Warrant Office properly endorsed or accompanied by appropriate
instruments of transfer and written instructions for transfer satisfactory to
the


                                      -3-
<PAGE>   4

Company. Upon any such transfer and upon payment by the Holder or its transferee
of any applicable transfer taxes, new Warrants shall be issued to the transferee
and the transferor (as their respective interests may appear) and the
surrendered Warrants shall be canceled by the Company. The Company shall pay all
taxes (other than securities transfer taxes or income taxes) and all other
expenses and charges payable in connection with the transfer of the Warrants
pursuant to this Section 2.3.

                  (b) Restrictions in General. The Holder of the Warrants agrees
that it will neither (i) transfer the Warrants prior to delivery to the Company
of written notice of such transfer, nor (ii) transfer such Warrant Shares prior
to delivery to the Company of written notice of such transfer, or until
registration of such Warrant Shares under the Securities Act and any applicable
state securities or Blue Sky laws has become effective.

         Section II.4 Compliance with Securities Laws. Subject to the terms of
the Registration Rights Agreement between the Holder and the Company dated as of
the date hereof and notwithstanding any other provisions contained in this
Warrant, the Holder hereof understands and agrees that the following
restrictions and limitations shall be applicable to all Warrant Shares and to
all resales or other transfers thereof pursuant to the Securities Act:

                  (a) The Holder hereof agrees that the Warrant Shares shall not
be sold or otherwise transferred unless the Warrant Shares are registered under
the Securities Act and applicable state securities or Blue Sky laws or are
exempt therefrom.

                  (b) A legend in substantially the following form will be
placed on the certificate(s) evidencing the Warrant Shares:

                           "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                  NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "SECURITIES ACT"), OR ANY OTHER APPLICABLE
                  SECURITIES LAW AND, ACCORDINGLY, THE SECURITIES REPRESENTED BY
                  THIS CERTIFICATE MAY NOT BE RESOLD, PLEDGED, OR OTHERWISE
                  TRANSFERRED, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
                  STATEMENT UNDER, OR IN A TRANSACTION EXEMPT FROM REGISTRATION
                  UNDER, THE SECURITIES ACT AND IN ACCORDANCE WITH ANY OTHER
                  APPLICABLE SECURITIES LAWS."

                  (c) Stop transfer instructions will be imposed with respect to
the Warrant Shares so as to restrict resale or other transfer thereof, subject
to this Section 2.4.

                  (d) The Holder understands that it must bear the economic risk
of the investment for an indefinite period of time because the Warrant Shares
have not been registered under the Securities Act and therefor cannot be sold
unless they are subsequently registered under the Securities Act or an exemption
from such registration is available. The Holder acknowledges that the Holder or
the Holder's representative is familiar with the condition, financial and
otherwise, of the Company. The Holder or the Holder's representative has such
knowledge and experience in financial and business matters that the Holder or
the Holder's representative is able to weigh the information so received and to
evaluate the merits and risks of the Holder's investment in the Warrant Shares.

                                   ARTICLE III
                                  ANTI-DILUTION

         Section III.1 Anti-Dilution Provisions. The Exercise Price shall be
subject to adjustment from time to time as hereinafter provided. Upon each
adjustment of the Exercise Price, the Holder of this Warrant shall thereafter be
entitled to purchase, at the Exercise Price resulting from such adjustment, the
number of shares of Common Stock obtained by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

         Section III.2 Adjustment of Exercise Price Upon Issuance of Common
Stock.

                  (a) (i) If and whenever after the date hereof the Company
         shall issue or sell any Common Stock for no consideration or for a
         consideration per share less than the Exercise Price, then, forthwith
         upon such issue or sale, the Exercise Price shall be reduced (but not
         increased, except as otherwise specifically provided in Section 3.2
         hereof), to the price (calculated to the nearest one-ten thousandth of
         a cent) determined by dividing (x) an amount equal to the sum of (i)
         the aggregate number of shares of Common Stock Outstanding immediately
         prior to such issue or sale multiplied by the consideration received by
         the Company upon such issuance or sale on a per share basis plus (ii)
         the consideration received by the Company upon such issue or sale by
         (y) the aggregate number of shares of Common Stock Outstanding
         immediately after such issue or sale.

                      (ii) Notwithstanding the provisions of this Section 3.2,
         no adjustment shall be made in the Exercise Price in the event that the
         Company issues, in one or more transactions, (A) Common Stock or
         Convertible Securities upon exercise of any options issued to officers,
         directors or employees of the Company pursuant to a stock option plan
         or an employment, severance or consulting agreement as now or hereafter
         in effect, in each case approved by the Board of Directors (provided
         that the aggregate number of shares of Common Stock which may be
         issuable, including options issued prior to the date hereof, under all
         such employee plans and agreements shall at no time exceed the number
         of such shares of Common Stock that are issuable under currently
         effective employee plans and agreements); (B) Common Stock upon
         exercise of the Warrants or any other Warrant issued pursuant to the
         terms of the Agreement or otherwise issued to the Holder; (C) Common
         Stock upon exercise of any stock purchase Warrant or option (other than
         the options referred to in clause "(A)" above) or other convertible
         security outstanding on the date hereof; (D) Common Stock upon
         conversion of the Note; or (E) Common Stock issued as consideration in
         acquisitions. In addition, for purposes of calculating any adjustment
         of the Exercise Price as provided in this Section 3.2, all of the
         shares of Common Stock issuable pursuant to any of the foregoing shall
         be assumed to be Outstanding prior to the event causing such adjustment
         to be made.

                  (b) For purposes of this Section 3.2, the following Sections
         3.2(b)(i) to 3.2(b)(v) inclusive, shall be applicable:

                           (i) Issuance of Rights or Options. In case at any
         time after the date hereof the Company shall in any manner grant
         (whether directly or by assumption in a merger or otherwise) any rights
         to subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or securities convertible into or
         exchangeable for Common Stock (such convertible or exchangeable stock
         or securities being herein called "Convertible Securities"), whether or
         not such rights or options or the right to convert or exchange any such
         Convertible Securities are immediately exercisable, and the price per
         share for which shares of Common Stock are issuable upon the exercise
         of such rights or options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (A) the total amount, if
         any, received or receivable by the Company as consideration for the
         granting of such rights or options, plus the minimum aggregate amount
         of additional consideration, if any, payable to the Company upon the
         exercise of such rights or options, or plus, in the case of such rights
         or options that relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (B) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon the
         conversion or exchange of all such Convertible Securities issuable upon
         the exercise of such rights or options) shall be less than the Exercise
         Price in effect as of the date of granting such rights or options, then
         the total maximum number of shares of Common Stock issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         all such Convertible Securities issuable upon the exercise of such
         rights or options shall be deemed to be outstanding as of the date of
         the granting of such rights or options and to have been issued for such
         price per share, with the effect on the Exercise Price specified in
         Section 3.2(a) hereof. Except as provided in Section 3.2(b) hereof, no
         further adjustment of the Exercise Price shall be made upon the actual
         issuance of such Common Stock or of such Convertible Securities upon
         exercise of such rights or options or upon the actual issuance of such
         Common Stock upon conversion or exchange of such Convertible
         Securities.

                           (ii) Change in Option Price or Conversion Rate. Upon
         the happening of any of the following events, namely, if the purchase
         price provided for in any right or option referred to in Section
         3.2(b), the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         Section 3.2(b), or the rate at which any Convertible Securities
         referred to in Section 3.2(b), are convertible into or exchangeable for
         Common Stock shall change (other than under or by reason of provisions
         designed to protect against dilution), the Exercise Price then in
         effect hereunder shall forthwith be readjusted (increased or decreased,
         as the case may be) to the Exercise Price that would have been in
         effect at such time had such rights, options or Convertible Securities
         still outstanding provided for such changed purchase price, additional
         consideration or conversion rate, as the case may be, at the time
         initially granted, issued or sold. On the expiration of any such option
         or right referred to in Section 3.2(b), or on the termination of any
         such right to convert or exchange any such Convertible Securities
         referred to in Section 3.2(b), the Exercise Price then in effect
         hereunder shall forthwith be readjusted (increased or decreased, as the
         case may be) to the Exercise Price that would have been in effect at
         the time of such expiration or termination had such right, option or
         Convertible Securities, to the extent outstanding immediately prior to
         such expiration or termination, never been granted, issued or sold, and
         the Common Stock issuable thereunder shall no longer be deemed to be
         Outstanding. If the purchase price provided for in Section 3.2(b) or
         the rate at which any Convertible Securities referred to in Section
         3.2(b) reduced at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible
         Securities, the Exercise Price then in effect hereunder shall, if not
         already adjusted, forthwith be adjusted to such amount as would have
         obtained had such right, option or Convertible Securities never been
         issued as to such Common Stock and had adjustments been made upon the
         issuance of the Common Stock delivered as aforesaid, but only if as a
         result of such adjustment the Exercise Price then in effect hereunder
         is thereby reduced.

                           (iii) Consideration for Stock. In case at any time
         Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for cash, the consideration therefor shall be deemed to
         be the amount received by the Company therefor. In case at any time any
         Common Stock, Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for consideration other than cash, the amount of the
         consideration other than cash received by the Company shall be deemed
         to be the fair value of such consideration, as determined reasonably
         and in good faith by the Board of Directors of the Company. In case at
         any time any Common Stock, Convertible Securities or any rights or
         options to purchase any Common Stock or Convertible Securities shall be
         issued in connection with any merger or consolidation in which the
         Company is the surviving corporation, the amount of consideration
         received therefor shall be deemed to be the fair value, as determined
         reasonably and in good faith by the Board of Directors of the Company,
         of such portion of the assets and business of the nonsurviving
         corporation as such Board of Directors may determine to be attributable
         to such Common Stock, Convertible Securities, rights or options as the
         case may be. In case at any time any rights or options to purchase any
         shares of Common Stock or Convertible Securities shall be issued in
         connection with the issuance and sale of other securities of the
         Company, together consisting of one integral transaction in which no
         consideration is allocated to such rights or options by the parties,
         such rights or options shall be deemed to have been issued with
         consideration.

                           (iv) Record Date. In the case the Company shall take
         a record of the holders of its Common Stock for the purpose of
         entitling them (i) to receive a dividend or other distribution payable
         in Common Stock or Convertible Securities, or (ii) to subscribe for or
         purchase Common Stock or Convertible Securities, then such record date
         shall be deemed to be the date of the issuance or sale of the Common
         Stock or Convertible Securities deemed to have been issued or sold as a
         result of the declaration of such dividend or the making of such other
         distribution or the date of the granting of such right of subscription
         or purchase, as the case may be.

                           (v) Treasury Shares. The number of shares of Common
         Stock Outstanding at any given time shall not include shares owned
         directly by the Company in treasury, and the disposition of any such
         shares shall be considered an issuance or sale of Common Stock for the
         purpose of this Section 3.2.

         Section III.3 Stock Dividends. In case the Company shall declare a
dividend or make any other distribution upon any shares of the Company, payable
in Common Stock or Convertible Securities, any Common Stock


                                      -6-
<PAGE>   7

or Convertible Securities, as the case may be, issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold without
consideration.

         Section III.4 Stock Splits and Reverse Splits. In the event that the
Company shall at any time subdivide its Outstanding shares of Common Stock into
a greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Warrant
Shares purchasable pursuant to this Warrant immediately prior to such
subdivision shall be proportionately increased, and conversely, in the event
that the Outstanding shares of Common Stock shall at any time be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
purchasable upon the exercise of this Warrant immediately prior to such
combination shall be proportionately reduced. Except as provided in this Section
3.4, no adjustment in the Exercise Price and no change in the number of Warrant
Shares purchasable shall be made under this Article III as a result of or by
reason of any such subdivision or combination.

         Section III.5 Reorganizations and Asset Sales. If any capital
reorganization or reclassification of the capital stock of the Company, or any
consolidation, merger or share exchange of the Company with another person, or
the sale, transfer or other disposition of all or substantially all of its
assets to another person shall be effected in such a way that a holder of Common
Stock of the Company shall be entitled to receive capital stock, securities or
assets with respect to or in exchange for their shares, then the following
provisions shall apply:

                  (a) As a condition of such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer or other disposition
(except as otherwise provided below in this Section 3.5), lawful and adequate
provisions shall be made whereby the holder of Warrants shall thereafter have
the right to purchase and receive upon the terms and conditions specified in
this Warrant and in lieu of the Warrant Shares immediately theretofore
receivable upon the exercise of the rights represented hereby, such shares of
capital stock, securities or assets as may be issued or payable with respect to
or in exchange for a number of Outstanding shares of such Common Stock equal to
the number of Warrant Shares immediately theretofore so receivable had such
reorganization, reclassification, consolidation, merger, share exchange or sale
not taken place, and in any such case appropriate provision reasonably
satisfactory to such holder shall be made with respect to the rights and
interests of such holder to the end that the provisions hereof (including,
without limitation, provisions for adjustments of the Exercise Price and of the
number of Warrant Shares receivable upon the exercise) shall thereafter be
applicable, as nearly as possible, in relation to any shares of capital stock,
securities or assets thereafter deliverable upon the exercise of Warrants.

                  (b) In the event of a merger, share exchange or consolidation
of the Company with or into another person as a result of which a number of
shares of Common Stock or its equivalent of the successor person greater or
lesser than the number of shares of Common Stock Outstanding immediately prior
to such merger, share exchange or consolidation are issuable to holders of
Common Stock, then the Exercise Price in effect immediately prior to such
merger, share exchange or consolidation shall be adjusted in the same manner as
though there were a subdivision or combination of the Outstanding shares of
Common Stock.

                  (c) The Company shall not effect any such consolidation,
merger, share exchange, sale, transfer or other disposition unless prior to or
simultaneously with the consummation thereof the successor person (if other than
the Company) resulting from such consolidation, share exchange or merger or the
person purchasing or otherwise acquiring such assets shall have assumed by
written instrument executed and mailed or delivered to the Holder hereof at the
last address of such holder appearing on the books of the Company the obligation
to deliver to such holder such shares of capital stock, securities or assets as,
in accordance with the foregoing provisions, such holder may be entitled to
receive, and all other liabilities and obligations of the Company hereunder.
Upon written request by the Holder hereof, such successor person will issue a
new Warrant revised to reflect the modifications in this Warrant effected
pursuant to this Section 3.5.

                  (d) If a purchase, tender or exchange offer is made to and
accepted by the holders of 50% or more of the Outstanding shares of Common
Stock, the Company shall not effect any consolidation, merger, share exchange or
sale, transfer or other disposition of all or substantially all of the Company's
assets with the person having made such offer or with any affiliate of such
person, unless prior to the consummation of such consolidation, merger, share
exchange, sale, transfer or other disposition the Holder hereof shall have been
given a reasonable opportunity to


                                      -7-
<PAGE>   8

then elect to receive upon the exercise of the Warrants either the capital
stock, securities or assets then issuable with respect to the Common Stock or
the capital stock, securities or assets, or the equivalent, issued to previous
holders of the Common Stock in accordance with such offer.

         Section III.6 Adjustment for Asset Distribution. If the Company
declares a dividend or other distribution payable to all holders of shares of
Common Stock in evidences of indebtedness of the Company or other assets of the
Company (including, cash (other than regular cash dividends declared by the
Board of Directors), capital stock (other than Common Stock, Convertible
Securities or options or rights thereto) or other property), the Exercise Price
in effect immediately prior to such declaration of such dividend or other
distribution shall be reduced by an amount equal to the amount of such dividend
or distribution payable per share of Common Stock, in the case of a cash
dividend or distribution, or by the fair value of such dividend or distribution
per share of Common Stock (as reasonably determined in good faith by the Board
of Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for purpose
of such dividend or distribution or, if a record is not taken, the date as of
which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         Section III.7 De Minimis Adjustments. No adjustment in the number of
shares of Common Stock purchasable hereunder shall be required unless such
adjustment would require an increase or decrease of at least one share of Common
Stock purchasable upon an exercise of each Warrant and no adjustment in the
Exercise Price shall be required unless such adjustment would require an
increase or decrease of at least $0.01 in the Exercise Price; provided, however,
that any adjustments which by reason of this Section 3.7 are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations shall be made to the nearest full share or nearest
one-hundredth of a dollar, as applicable.

         Section III.8 Notice of Adjustment. Whenever the Exercise Price or the
number of Warrant Shares issuable upon the exercise of the Warrants shall be
adjusted as herein provided, or the rights of the Holder hereof shall change by
reason of other events specified herein, the Company shall compute the adjusted
Exercise Price and the adjusted number of Warrant Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate setting forth the
adjusted Exercise Price and the adjusted number of Warrant Shares issuable upon
the exercise of the Warrants or specifying the other shares of stock, securities
or assets receivable as a result of such change in rights, and showing in
reasonable detail the facts and calculations upon which such adjustments or
other changes are based. The Company shall cause to be mailed to the Holder
hereof copies of such Officer's Certificate together with a notice stating that
the Exercise Price and the number of Warrant Shares purchasable upon exercise of
the Warrants have been adjusted and setting forth the adjusted Exercise Price
and the adjusted number of Warrant Shares purchasable upon the exercise of the
Warrants.

         Section III.9  Notifications to Holders. In case at any time the
Company proposes:

                  (a) to declare any dividend upon its Common Stock payable in
capital stock or make any special dividend or other distribution (other than
cash dividends) to the holders of its Common Stock;

                  (b) to offer for subscription pro rata to all of the holders
of its Common Stock any additional shares of capital stock of any class or other
rights;

                  (c) to effect any capital reorganization, or reclassification
of the capital stock of the Company, or consolidation, merger or share exchange
of the Company with another person, or sale, transfer or other disposition of
all or substantially all of its assets; or

                  (d) to effect a voluntary or involuntary dissolution,
liquidation or winding up of the Company, then, in any one or more of such
cases, the Company shall give the Holder hereof (a) at least ten (10) days' (but
not more than ninety (90) days') prior written notice of the date of which the
books of the Company shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of such issuance, reorganization, reclassification, consolidation, merger, share
exchange, sale, transfer, disposition, dissolution, liquidation or winding up,
and (b) in the case of any such issuance, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, at least ten (10) days' (but not


                                      -8-
<PAGE>   9

more than ninety (90) days') prior written notice of the date when the same
shall take place. Such notice in accordance with the foregoing clause "(a)"
shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause "(b)"
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock, as the case may be, for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, as the case may be.

         Section III.10 Company to Prevent Dilution. If any event or condition
occurs as to which other provisions of this Article III are not strictly
applicable or if strictly applicable would not fairly protect the exercise or
purchase rights of the Warrants evidenced hereby in accordance with the
essential intent and principles of such provisions, or that might materially and
adversely affect the exercise or purchase rights of the Holder hereof under any
provisions of this Warrant, then the Company shall make such adjustments in the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such exercise and purchase rights as aforesaid, and
any adjustments necessary with respect to the Exercise Price and the number of
Warrant Shares purchasable hereunder so as to preserve the rights of the Holder
hereunder. In no event shall any such adjustment have the effect of increasing
the Exercise Price as otherwise determined pursuant to this Article III except
in the event of a combination of shares of the type contemplated in Section 3.4
hereof, and then in no event to an amount greater than the Exercise Price as
adjusted pursuant to Section 3.4 hereof.

                                   ARTICLE IV
                                  MISCELLANEOUS

         Section IV.1 Entire Agreement. This Warrant, together with the
Agreement, contain the entire agreement between the Holder hereof and the

the related transactions and supersedes all prior arrangements or understandings
with respect thereto.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

         Section IV.3 Waiver and Amendment. Any term or provision of this
Warrant may be waived at any time by the party which is entitled to the benefits
thereof and any term or provision of this Warrant may be amended or supplemented
at any time by agreement of the Holder hereof and the Company, except that any
waiver of any term or condition, or any amendment or supplementation, of this
Warrant shall be in writing. A waiver of any breach or failure to enforce any of
the terms or conditions of this Warrant shall not in any way effect, limit or
waive a party's rights hereunder at any time to enforce strict compliance
thereafter with every term or condition of this Warrant.

         Section IV.4 Illegality. In the event that any one or more of the
provisions contained in this Warrant shall be determined to be invalid, illegal
or unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision in any other respect and the remaining
provisions of this Warrant shall not, at the election of the party for whom the
benefit of the provision exists, be in any way impaired.

         Section IV.5 Copy of Warrant. A copy of this Warrant shall be filed
among the records of the Company.

         Section IV.6 Notice. All notices, requests, demands or other
communications to or upon the respective parties hereto shall be deemed to have
been duly given or made when delivered to the party to which such notice,

expressly provided) in respect of meetings of stockholders for the election of

                              EXERCISE OF WARRANTS

         Section I.1 Method of Exercise. The Warrants represented hereby may be
exercised by the Holder hereof, in whole or in part, at any time and from time
to time on or after the date hereof until 5:00 p.m., Houston, Texas time, on
August 12, 2004 (the "Exercise Date"). To exercise the Warrants, the Holder
hereof shall deliver to the Company, at the Warrant Office designated in Section
2.1 hereof, (i) a written notice in the form of the Subscription Notice attached
as an exhibit hereto, stating therein the election of such holder to exercise
the Warrants in the manner provided in the Subscription Notice; (ii) payment in
full of the Exercise Price (A) in cash or immediately available funds for all
Warrant Shares purchased hereunder, or (B) if the Company and the Holder
mutually elect, through a "cashless" or "net-issue" exercise of each such
Warrant ("Cashless Exercise"); the Holder shall exchange each Warrant subject to
a Cashless Exercise for that number of Warrant Shares determined by multiplying
the number of Warrant Shares issuable hereunder by a fraction, the numerator of
which shall be the difference between (x) the Market Price and (y) the Exercise
Price for each such Warrant, and the denominator of which shall be the Market
Price; the Subscription Notice shall set forth the calculation upon which the
Cashless Exercise is based, or (C) a combination of (A) and (B) above; and (iii)
this Warrant. The Warrants shall be deemed to be exercised on the date of
receipt by the Company of the Subscription Notice, accompanied by payment for
the Warrant Shares and surrender of this Warrant, as aforesaid, and such date is
referred to herein as the "Exercise Date". Upon such exercise, the Company
shall, as promptly as practicable and in any event within ten (10) business
days, issue and deliver to such holder a certificate or certificates for the
full number of the Warrant Shares purchased by such holder hereunder, and shall,
unless the Warrants have expired, deliver to the Holder hereof a new Warrant
representing the number of Warrants, if any, that shall not have been exercised,
in all other respects identical to this Warrant. As permitted by applicable law,
the person in whose name the certificates for Common Stock are to be issued
shall be deemed to have become a holder of record of such Common Stock on the
Exercise Date and shall be entitled to all of the benefits of such holder on the
Exercise Date, including without limitation the right to receive dividends and
other distributions for which the record date falls on or after the Exercise
Date and to exercise voting rights.

         Section I.2 Expenses and Taxes. The Company shall pay all expenses, and
taxes (including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.



                                      -2-
<PAGE>   3



         Section I.3 Reservation of Shares. The Company shall reserve at all
times so long as the Warrants remain outstanding, free from preemptive rights,
out of its treasury Common Stock or its authorized but unissued shares of Common
Stock, or both, solely for the purpose of effecting the exercise of the
Warrants, a sufficient number of shares of Common Stock to provide for the
exercise of the Warrants.

         Section I.4 Valid Issuance. All shares of Common Stock that may be
issued upon exercise of the Warrants will, upon issuance by the Company, be duly
and validly issued, fully paid and nonassessable and free from all taxes, liens
and charges with respect to the issuance thereof and, without limiting the
generality of the foregoing, the Company shall take no action or fail to take
any action which will cause a contrary result (including, without limitation,
any action that would cause the Exercise Price to be less than the par value, if
any, of the Common Stock).

         Section I.5 Purchase Agreement. The Warrants represented hereby are
part of a duly authorized issuance and sale of Warrants to purchase Common Stock
issued and sold pursuant to the Loan Agreement between Holder and Company of
even date herewith.

         Section I.6 Acknowledgment of Rights. At the time of the exercise of
the Warrants in accordance with the terms hereof and upon the written request of
the Holder hereof, the Company will acknowledge in writing its continuing
obligation to afford to such holder any rights (including, without limitation,
any right to registration of the Warrant Shares) to which such holder shall
continue to be entitled after such exercise in accordance with the provisions of
this Warrant; provided, however, that if the Holder hereof shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such holder any such rights.

         Section I.7 No Fractional Shares. The Company shall not be required to
issue fractional shares of Common Stock on the exercise of this Warrant. If more
than one Warrant shall be presented for exercise at the same time by the same
holder, the number of full shares of Common Stock which shall be issuable upon
such exercise shall be computed on the basis of the aggregate number of whole
shares of Common Stock purchasable on exercise of the Warrants so presented. If
any fraction of a share of Common Stock would, except for the provisions of this
Section 1.7, be issuable on the exercise of this Warrant, the Company shall pay
an amount in cash calculated by it to be equal to the Market Price of one share
of Common Stock at the time of such exercise multiplied by such fraction
computed to the nearest whole cent.

                                   ARTICLE II
                                    TRANSFER

         Section II.1 Warrant Office. The Company shall maintain an office for
certain purposes specified herein (the "Warrant Office"), which office shall
initially be the Company's offices at 1100 Executive Drive, Richardson, Texas
75081 and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the Holder hereof. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

         Section II.2 Ownership of Warrants. The Company may deem and treat the
person in whose name the Warrants are registered as the Holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Article II. Notwithstanding the foregoing, the Warrants
represented hereby, if properly assigned in compliance with this Article II, may
be exercised by an assignee for the purchase of Warrant Shares without having a
new Warrant issued.

         Section  II.3     Restrictions on Transfer of Warrants.

                  (a) The Company agrees to maintain at the Warrant Office books
for the registration and transfer of the Warrants. Subject to the restrictions
on transfer of the Warrants in this Section 2.3, the Company, from time to time,
shall register the transfer of the Warrants in such books upon surrender of this
Warrant at the Warrant Office properly endorsed or accompanied by appropriate
instruments of transfer and written instructions for transfer satisfactory to
the



                                      -3-
<PAGE>   4

Company. Upon any such transfer and upon payment by the Holder or its transferee
of any applicable transfer taxes, new Warrants shall be issued to the transferee
and the transferor (as their respective interests may appear) and the
surrendered Warrants shall be canceled by the Company. The Company shall pay all
taxes (other than securities transfer taxes or income taxes) and all other
expenses and charges payable in connection with the transfer of the Warrants
pursuant to this Section 2.3.

                  (b) Restrictions in General. The Holder of the Warrants agrees
that it will neither (i) transfer the Warrants prior to delivery to the Company
of written notice of such transfer, nor (ii) transfer such Warrant Shares prior
to delivery to the Company of written notice of such transfer, or until
registration of such Warrant Shares under the Securities Act and any applicable
state securities or Blue Sky laws has become effective.

         Section II.4 Compliance with Securities Laws. Subject to the terms of
the Registration Rights Agreement between the Holder and the Company dated as of
the date hereof and notwithstanding any other provisions contained in this
Warrant, the Holder hereof understands and agrees that the following
restrictions and limitations shall be applicable to all Warrant Shares and to
all resales or other transfers thereof pursuant to the Securities Act:

                  (a) The Holder hereof agrees that the Warrant Shares shall not
be sold or otherwise transferred unless the Warrant Shares are registered under
the Securities Act and applicable state securities or Blue Sky laws or are
exempt therefrom.

                  (b) A legend in substantially the following form will be
placed on the certificate(s) evidencing the Warrant Shares:

                           "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
                  NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "SECURITIES ACT"), OR ANY OTHER APPLICABLE
                  SECURITIES LAW AND, ACCORDINGLY, THE SECURITIES REPRESENTED BY
                  THIS CERTIFICATE MAY NOT BE RESOLD, PLEDGED, OR OTHERWISE
                  TRANSFERRED, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
                  STATEMENT UNDER, OR IN A TRANSACTION EXEMPT FROM REGISTRATION
                  UNDER, THE SECURITIES ACT AND IN ACCORDANCE WITH ANY OTHER
                  APPLICABLE SECURITIES LAWS."

                  (c) Stop transfer instructions will be imposed with respect to
the Warrant Shares so as to restrict resale or other transfer thereof, subject
to this Section 2.4.

                  (d) The Holder understands that it must bear the economic risk
of the investment for an indefinite period of time because the Warrant Shares
have not been registered under the Securities Act and therefor cannot be sold
unless they are subsequently registered under the Securities Act or an exemption
from such registration is available. The Holder acknowledges that the Holder or
the Holder's representative is familiar with the condition, financial and
otherwise, of the Company. The Holder or the Holder's representative has such
knowledge and experience in financial and business matters that the Holder or
the Holder's representative is able to weigh the information so received and to
evaluate the merits and risks of the Holder's investment in the Warrant Shares.

                                   ARTICLE III
                                  ANTI-DILUTION

         Section III.1 Anti-Dilution Provisions. The Exercise Price shall be
subject to adjustment from time to time as hereinafter provided. Upon each
adjustment of the Exercise Price, the Holder of this Warrant shall thereafter be
entitled to purchase, at the Exercise Price resulting from such adjustment, the
number of shares of Common Stock obtained by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

         Section III.2 Adjustment of Exercise Price Upon Issuance of Common
Stock.

                  (a)      (i) If and whenever after the date hereof the Company
         shall issue or sell any Common Stock for no consideration or for a
         consideration per share less than the Exercise Price, then, forthwith
         upon such issue or sale, the Exercise Price shall be reduced (but not
         increased, except as otherwise specifically provided in Section 3.2
         hereof), to the price (calculated to the nearest one-ten thousandth of
         a cent) determined by dividing (x) an amount equal to the sum of (i)
         the aggregate number of shares of Common Stock Outstanding immediately
         prior to such issue or sale multiplied by the consideration received by
         the Company upon such issuance or sale on a per share basis plus (ii)
         the consideration received by the Company upon such issue or sale by
         (y) the aggregate number of shares of Common Stock Outstanding
         immediately after such issue or sale.

                           (ii) Notwithstanding the provisions of this Section
         3.2, no adjustment shall be made in the Exercise Price in the event
         that the Company issues, in one or more transactions, (A) Common Stock
         or Convertible Securities upon exercise of any options issued to
         officers, directors or employees of the Company pursuant to a stock
         option plan or an employment, severance or consulting agreement as now
         or hereafter in effect, in each case approved by the Board of Directors
         (provided that the aggregate number of shares of Common Stock which may
         be issuable, including options issued prior to the date hereof, under
         all such employee plans and agreements shall at no time exceed the
         number of such shares of Common Stock that are issuable under currently
         effective employee plans and agreements); (B) Common Stock upon
         exercise of the Warrants or any other Warrant issued pursuant to the
         terms of the Agreement or otherwise issued to the Holder; (C) Common
         Stock upon exercise of any stock purchase Warrant or option (other than
         the options referred to in clause "(A)" above) or other convertible
         security outstanding on the date hereof; (D) Common Stock upon
         conversion or redemption of the Note; or (E) Common Stock issued as
         consideration in acquisitions. In addition, for purposes of calculating
         any adjustment of the Exercise Price as provided in this Section 3.2,
         all of the shares of Common Stock issuable pursuant to any of the
         foregoing shall be assumed to be Outstanding prior to the event causing
         such adjustment to be made.

                  (b) For purposes of this Section 3.2, the following Sections
         3.2(b)(i) to 3.2(b)(v) inclusive, shall be applicable:

                           (i) Issuance of Rights or Options. In case at any
         time after the date hereof the Company shall in any manner grant
         (whether directly or by assumption in a merger or otherwise) any rights
         to subscribe for or to purchase, or any options for the purchase of,
         Common Stock or any stock or securities convertible into or
         exchangeable for Common Stock (such convertible or exchangeable stock
         or securities being herein called "Convertible Securities"), whether or
         not such rights or options or the right to convert or exchange any such
         Convertible Securities are immediately exercisable, and the price per
         share for which shares of Common Stock are issuable upon the exercise
         of such rights or options or upon conversion or exchange of such
         Convertible Securities (determined by dividing (A) the total amount, if
         any, received or receivable by the Company as consideration for the
         granting of such rights or options, plus the minimum aggregate amount
         of additional consideration, if any, payable to the Company upon the
         exercise of such rights or options, or plus, in the case of such rights
         or options that relate to Convertible Securities, the minimum aggregate
         amount of additional consideration, if any, payable upon the issue or
         sale of such Convertible Securities and upon the conversion or exchange
         thereof, by (B) the total maximum number of shares of Common Stock
         issuable upon the exercise of such rights or options or upon the
         conversion or exchange of all such Convertible Securities issuable upon
         the exercise of such rights or options) shall be less than the Exercise
         Price in effect as of the date of granting such rights or options, then
         the total maximum number of shares of Common Stock issuable upon the
         exercise of such rights or options or upon conversion or exchange of
         all such Convertible Securities issuable upon the exercise of such
         rights or options shall be deemed to be outstanding as of the date of
         the granting of such rights or options and to have been issued for such
         price per share, with the effect on the Exercise Price specified in
         Section 3.2(a) hereof. Except as provided in Section 3.2(b) hereof, no
         further adjustment of the Exercise Price shall be made upon the actual
         issuance of such Common Stock or of such Convertible Securities upon
         exercise of such rights or options or upon the actual issuance of such
         Common Stock upon conversion or exchange of such Convertible
         Securities.

<PAGE>   6

                           (ii) Change in Option Price or Conversion Rate. Upon
         the happening of any of the following events, namely, if the purchase
         price provided for in any right or option referred to in Section
         3.2(b), the additional consideration, if any, payable upon the
         conversion or exchange of any Convertible Securities referred to in
         Section 3.2(b), or the rate at which any Convertible Securities
         referred to in Section 3.2(b), are convertible into or exchangeable for
         Common Stock shall change (other than under or by reason of provisions
         designed to protect against dilution), the Exercise Price then in
         effect hereunder shall forthwith be readjusted (increased or decreased,
         as the case may be) to the Exercise Price that would have been in
         effect at such time had such rights, options or Convertible Securities
         still outstanding provided for such changed purchase price, additional
         consideration or conversion rate, as the case may be, at the time
         initially granted, issued or sold. On the expiration of any such option
         or right referred to in Section 3.2(b), or on the termination of any
         such right to convert or exchange any such Convertible Securities
         referred to in Section 3.2(b), the Exercise Price then in effect
         hereunder shall forthwith be readjusted (increased or decreased, as the
         case may be) to the Exercise Price that would have been in effect at
         the time of such expiration or termination had such right, option or
         Convertible Securities, to the extent outstanding immediately prior to
         such expiration or termination, never been granted, issued or sold, and
         the Common Stock issuable thereunder shall no longer be deemed to be
         Outstanding. If the purchase price provided for in Section 3.2(b) or
         the rate at which any Convertible Securities referred to in Section
         3.2(b) reduced at any time under or by reason of provisions with
         respect thereto designed to protect against dilution, then in case of
         the delivery of Common Stock upon the exercise of any such right or
         option or upon conversion or exchange of any such Convertible
         Securities, the Exercise Price then in effect hereunder shall, if not
         already adjusted, forthwith be adjusted to such amount as would have
         obtained had such right, option or Convertible Securities never been
         issued as to such Common Stock and had adjustments been made upon the
         issuance of the Common Stock delivered as aforesaid, but only if as a
         result of such adjustment the Exercise Price then in effect hereunder
         is thereby reduced.

                           (iii) Consideration for Stock. In case at any time
         Common Stock or Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for cash, the consideration therefor shall be deemed to
         be the amount received by the Company therefor. In case at any time any
         Common Stock, Convertible Securities or any rights or options to
         purchase any such Common Stock or Convertible Securities shall be
         issued or sold for consideration other than cash, the amount of the
         consideration other than cash received by the Company shall be deemed
         to be the fair value of such consideration, as determined reasonably
         and in good faith by the Board of Directors of the Company. In case at
         any time any Common Stock, Convertible Securities or any rights or
         options to purchase any Common Stock or Convertible Securities shall be
         issued in connection with any merger or consolidation in which the
         Company is the surviving corporation, the amount of consideration
         received therefor shall be deemed to be the fair value, as determined
         reasonably and in good faith by the Board of Directors of the Company,
         of such portion of the assets and business of the nonsurviving
         corporation as such Board of Directors may determine to be attributable
         to such Common Stock, Convertible Securities, rights or options as the
         case may be. In case at any time any rights or options to purchase any
         shares of Common Stock or Convertible Securities shall be issued in
         connection with the issuance and sale of other securities of the
         Company, together consisting of one integral transaction in which no
         consideration is allocated to such rights or options by the parties,
         such rights or options shall be deemed to have been issued with
         consideration.

                           (iv) Record Date. In the case the Company shall take
         a record of the holders of its Common Stock for the purpose of
         entitling them (i) to receive a dividend or other distribution payable
         in Common Stock or Convertible Securities, or (ii) to subscribe for or
         purchase Common Stock or Convertible Securities, then such record date
         shall be deemed to be the date of the issuance or sale of the Common
         Stock or Convertible Securities deemed to have been issued or sold as a
         result of the declaration of such dividend or the making of such other
         distribution or the date of the granting of such right of subscription
         or purchase, as the case may be.

                           (v) Treasury Shares. The number of shares of Common
         Stock Outstanding at any given time shall not include shares owned
         directly by the Company in treasury, and the disposition of any such
         shares shall be considered an issuance or sale of Common Stock for the
         purpose of this Section 3.2.

         Section III.3 Stock Dividends. In case the Company shall declare a
dividend or make any other distribution upon any shares of the Company, payable
in Common Stock or Convertible Securities, any Common Stock



                                      -6-
<PAGE>   7

or Convertible Securities, as the case may be, issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold without
consideration.

         Section III.4 Stock Splits and Reverse Splits. In the event that the
Company shall at any time subdivide its Outstanding shares of Common Stock into
a greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Warrant
Shares purchasable pursuant to this Warrant immediately prior to such
subdivision shall be proportionately increased, and conversely, in the event
that the Outstanding shares of Common Stock shall at any time be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
purchasable upon the exercise of this Warrant immediately prior to such
combination shall be proportionately reduced. Except as provided in this Section
3.4, no adjustment in the Exercise Price and no change in the number of Warrant
Shares purchasable shall be made under this Article III as a result of or by
reason of any such subdivision or combination.

         Section III.5 Reorganizations and Asset Sales. If any capital
reorganization or reclassification of the capital stock of the Company, or any
consolidation, merger or share exchange of the Company with another person, or
the sale, transfer or other disposition of all or substantially all of its
assets to another person shall be effected in such a way that a holder of Common
Stock of the Company shall be entitled to receive capital stock, securities or
assets with respect to or in exchange for their shares, then the following
provisions shall apply:

                  (a) As a condition of such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer or other disposition
(except as otherwise provided below in this Section 3.5), lawful and adequate
provisions shall be made whereby the holder of Warrants shall thereafter have
the right to purchase and receive upon the terms and conditions specified in
this Warrant and in lieu of the Warrant Shares immediately theretofore
receivable upon the exercise of the rights represented hereby, such shares of
capital stock, securities or assets as may be issued or payable with respect to
or in exchange for a number of Outstanding shares of such Common Stock equal to
the number of Warrant Shares immediately theretofore so receivable had such
reorganization, reclassification, consolidation, merger, share exchange or sale
not taken place, and in any such case appropriate provision reasonably
satisfactory to such holder shall be made with respect to the rights and
interests of such holder to the end that the provisions hereof (including,
without limitation, provisions for adjustments of the Exercise Price and of the
number of Warrant Shares receivable upon the exercise) shall thereafter be
applicable, as nearly as possible, in relation to any shares of capital stock,
securities or assets thereafter deliverable upon the exercise of Warrants.

                  (b) In the event of a merger, share exchange or consolidation
of the Company with or into another person as a result of which a number of
shares of Common Stock or its equivalent of the successor person greater or
lesser than the number of shares of Common Stock Outstanding immediately prior
to such merger, share exchange or consolidation are issuable to holders of
Common Stock, then the Exercise Price in effect immediately prior to such
merger, share exchange or consolidation shall be adjusted in the same manner as
though there were a subdivision or combination of the Outstanding shares of
Common Stock.

                  (c) The Company shall not effect any such consolidation,
merger, share exchange, sale, transfer or other disposition unless prior to or
simultaneously with the consummation thereof the successor person (if other than
the Company) resulting from such consolidation, share exchange or merger or the
person purchasing or otherwise acquiring such assets shall have assumed by
written instrument executed and mailed or delivered to the Holder hereof at the
last address of such holder appearing on the books of the Company the obligation
to deliver to such holder such shares of capital stock, securities or assets as,
in accordance with the foregoing provisions, such holder may be entitled to
receive, and all other liabilities and obligations of the Company hereunder.
Upon written request by the Holder hereof, such successor person will issue a
new Warrant revised to reflect the modifications in this Warrant effected
pursuant to this Section 3.5.

                  (d) If a purchase, tender or exchange offer is made to and
accepted by the holders of 50% or more of the Outstanding shares of Common
Stock, the Company shall not effect any consolidation, merger, share exchange or
sale, transfer or other disposition of all or substantially all of the Company's
assets with the person having made such offer or with any affiliate of such
person, unless prior to the consummation of such consolidation, merger, share
exchange, sale, transfer or other disposition the Holder hereof shall have been
given a reasonable opportunity to



                                      -7-
<PAGE>   8

then elect to receive upon the exercise of the Warrants either the capital
stock, securities or assets then issuable with respect to the Common Stock or
the capital stock, securities or assets, or the equivalent, issued to previous
holders of the Common Stock in accordance with such offer.

         Section III.6 Adjustment for Asset Distribution. If the Company
declares a dividend or other distribution payable to all holders of shares of
Common Stock in evidences of indebtedness of the Company or other assets of the
Company (including, cash (other than regular cash dividends declared by the
Board of Directors), capital stock (other than Common Stock, Convertible
Securities or options or rights thereto) or other property), the Exercise Price
in effect immediately prior to such declaration of such dividend or other
distribution shall be reduced by an amount equal to the amount of such dividend
or distribution payable per share of Common Stock, in the case of a cash
dividend or distribution, or by the fair value of such dividend or distribution
per share of Common Stock (as reasonably determined in good faith by the Board
of Directors of the Company), in the case of any other dividend or distribution.
Such reduction shall be made whenever any such dividend or distribution is made
and shall be effective as of the date as of which a record is taken for purpose
of such dividend or distribution or, if a record is not taken, the date as of
which holders of record of Common Stock entitled to such dividend or
distribution are determined.

         Section III.7 De Minimis Adjustments. No adjustment in the number of
shares of Common Stock purchasable hereunder shall be required unless such
adjustment would require an increase or decrease of at least one share of Common
Stock purchasable upon an exercise of each Warrant and no adjustment in the
Exercise Price shall be required unless such adjustment would require an
increase or decrease of at least $0.01 in the Exercise Price; provided, however,
that any adjustments which by reason of this Section 3.7 are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations shall be made to the nearest full share or nearest
one-hundredth of a dollar, as applicable.

         Section III.8 Notice of Adjustment. Whenever the Exercise Price or the
number of Warrant Shares issuable upon the exercise of the Warrants shall be
adjusted as herein provided, or the rights of the Holder hereof shall change by
reason of other events specified herein, the Company shall compute the adjusted
Exercise Price and the adjusted number of Warrant Shares in accordance with the
provisions hereof and shall prepare an Officer's Certificate setting forth the
adjusted Exercise Price and the adjusted number of Warrant Shares issuable upon
the exercise of the Warrants or specifying the other shares of stock, securities
or assets receivable as a result of such change in rights, and showing in
reasonable detail the facts and calculations upon which such adjustments or
other changes are based. The Company shall cause to be mailed to the Holder
hereof copies of such Officer's Certificate together with a notice stating that
the Exercise Price and the number of Warrant Shares purchasable upon exercise of
the Warrants have been adjusted and setting forth the adjusted Exercise Price
and the adjusted number of Warrant Shares purchasable upon the exercise of the
Warrants.

         Section III.9 Notifications to Holders. In case at any time the Company
proposes:

                  (a) to declare any dividend upon its Common Stock payable in
capital stock or make any special dividend or other distribution (other than
cash dividends) to the holders of its Common Stock;

                  (b) to offer for subscription pro rata to all of the holders
of its Common Stock any additional shares of capital stock of any class or other
rights;

                  (c) to effect any capital reorganization, or reclassification
of the capital stock of the Company, or consolidation, merger or share exchange
of the Company with another person, or sale, transfer or other disposition of
all or substantially all of its assets; or

                  (d) to effect a voluntary or involuntary dissolution,
liquidation or winding up of the Company, then, in any one or more of such
cases, the Company shall give the Holder hereof (a) at least ten (10) days' (but
not more than ninety (90) days') prior written notice of the date of which the
books of the Company shall close or a record shall be taken for such dividend,
distribution or subscription rights or for determining rights to vote in respect
of such issuance, reorganization, reclassification, consolidation, merger, share
exchange, sale, transfer, disposition, dissolution, liquidation or winding up,
and (b) in the case of any such issuance, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, at least ten (10) days' (but not



                                      -8-
<PAGE>   9

more than ninety (90) days') prior written notice of the date when the same
shall take place. Such notice in accordance with the foregoing clause "(a)"
shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause "(b)"
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock, as the case may be, for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, as the case may be.

         Section III.10 Company to Prevent Dilution. If any event or condition
occurs as to which other provisions of this Article III are not strictly
applicable or if strictly applicable would not fairly protect the exercise or
purchase rights of the Warrants evidenced hereby in accordance with the
essential intent and principles of such provisions, or that might materially and
adversely affect the exercise or purchase rights of the Holder hereof under any
provisions of this Warrant, then the Company shall make such adjustments in the
application of such provisions, in accordance with such essential intent and
principles, so as to protect such exercise and purchase rights as aforesaid, and
any adjustments necessary with respect to the Exercise Price and the number of
Warrant Shares purchasable hereunder so as to preserve the rights of the Holder
hereunder. In no event shall any such adjustment have the effect of increasing
the Exercise Price as otherwise determined pursuant to this Article III except
in the event of a combination of shares of the type contemplated in Section 3.4
hereof, and then in no event to an amount greater than the Exercise Price as
adjusted pursuant to Section 3.4 hereof.

                                   ARTICLE IV

provisions contained in this Warrant shall be determined to be invalid, illegal

                               REGISTRATION RIGHTS

         2.1      Demand Registration.

                  2.1.1 Subject to the Subscription Agreement and the rules and
regulations of the Commission, at any time and from time to time, Purchaser may
make a one-time written demand upon the Company to file, within sixty (60) days
after such written demand is made, a registration statement covering the resale
of all of the Registrable Securities on Form S-1, S-2 or S-3 as appropriate with
the Commission (the "Demand Registration Statement"). The Company shall use its
reasonable best efforts to cause such Registration Statement to become effective
as soon after filing as practicable and to cause all of the Registrable
Securities to be qualified in such state jurisdictions as the holders may
request.

                  2.1.2 Except as set forth herein, the Company shall take all
reasonable steps necessary to keep the Registration Statement current and
effective until the lesser of: (i) two years and (ii) until the Registrable
Securities are transferable pursuant to Rule 144 under the Securities Act
without the volume limitations set forth in such rule.

                  2.1.3 The Company shall be entitled to require that a holder
or holders of Registrable Securities refrain from effecting any public sales or
distributions of the Registrable Securities pursuant to a Registration Statement
that has been declared effective by the Commission or otherwise, if the board of
directors of the Company reasonably determines that such public sales or
distributions would interfere in any material respect with any transaction
involving the Company that the board of directors reasonably determines to be
material to the Company. The board of directors shall, as promptly as
practicable, give the holders of the Registrable Securities written notice of
any such development. In the event of a request by the board of directors of the
Company that the holders of Registrable Securities refrain from effecting any
public sales or distributions of the Registrable Securities, the Company shall
be required to lift such restrictions regarding effecting public sales or
distributions of the Registrable Securities as soon as reasonably practicable
after the board of directors shall reasonably determine public sales or
distributions by the holders of the Registrable Securities shall not interfere
with such transaction, provided, that in no event shall any requirement that the
holders of Registrable Securities refrain from effecting public sales or
distributions if the Registrable Securities extend for more than ninety (90)
days.

                  2.1.4 Notwithstanding the foregoing, the one-time demand
registration rights provided in this Section 2.1 shall be subject to the
following additional limitations:

                  (i)      Company shall not be obligated to file such
                           Registration Statement on a Form S-2 or S-3 if it
                           does not then meet the requirements (including the
                           financial statement requirements) of such Form, and
                           if the Company is required to file a Form S-1, it
                           should not be obligated to file the Form S-1 until it
                           shall have prepared current financial statements as
                           required by Form S-1;

                  (ii)     If, upon receipt of any request for registration of
                           Registrable Securities pursuant to this Section 2.1,
                           the Company has then engaged a reputable and
                           nationally or regionally recognized securities or
                           investment banking firm for a registered public
                           offering of Shares of Common Stock, then the Company
                           shall give notice of such negotiations to all holders
                           of Registrable Securities within fifteen (15) days of
                           the date upon which the Company received such
                           holder's request and the Company shall not, for sixty
                           (60) days after giving such notice to such holders,
                           be required to undertake a required registration of
                           the Registrable Securities pursuant to this Section
                           2.1 in response to such holder's request; provided,
                           however, that if such registration statement of such
                           proposed public offering is not filed within sixty
                           (60) days after the Company gives such notice to
                           holders of the Registrable Securities, the Company
                           shall respond to the holder's request for
                           registration of Registrable Securities and, unless
                           otherwise required by the provisions of this Section
                           2.1, register such Registrable Securities, no later
                           than twenty (20) days after the expiration of such
                           sixty (60) day period and as provided herein.

         2.2      Piggyback Registration.

                  2.2.1 Subject to the terms hereof, if at any time or from time
to time the Company or any shareholder of the Company shall determine to
register any of its securities (except for registration statements relating to
employee benefit plans or exchange offers), either for its own account or the
account of a security holder, the Company will promptly give to the holders of
Registrable Securities written notice thereof not less than 30 days prior to the
filing of any registration statement; and include in such registration (and any
related qualification under Blue Sky laws or other compliance), and in the
underwriting involved therein, if any, such Registrable Securities as such
holders may request in a writing delivered to the Company within twenty (20)
days after the holders' receipt of Company's written notice.

                  2.2.2 The holders of Registrable Securities may participate in
any number of registrations until all of the Shares held by holders of
Registrable Securities have been distributed pursuant to a registration or until
the Shares are transferable pursuant to Rule 144 under the Securities Act.

                  2.2.3 If any registration statement is an Underwritten Public
Offering, the right of holders of Registrable Securities to registration
pursuant to this Section shall be conditioned upon each such holder's
participation in such reasonable underwriting arrangements as the Company shall
make regarding the offering, and the inclusion of Registrable Securities in the
underwriting shall be limited to the extent provided herein. Holders of
Registrable Securities and all other shareholders proposing to distribute their
securities through such underwriting shall (together with the Company and the
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the managing underwriter
selected for such underwriting by the Company. Notwithstanding any other
provision of this Section, if the managing underwriter concludes in its
reasonable judgment that the number of Shares to be registered for selling
shareholders (including the holders of Registrable Securities) would materially
adversely effect such offering, the number of Shares to be registered, together
with the number of Shares of Common Stock or other securities held by other
shareholders proposed to be registered in such offering, shall be reduced on a
pro rata basis based on the number of Shares proposed to be sold by the holders
of



                                      -3-
<PAGE>   4

Registrable Securities as compared to the number of Shares proposed to be sold
by all shareholders. If any holder of Registrable Securities disapproves of the
terms of any such underwriting, it may elect to withdraw therefrom by written
notice to the Company and the managing underwriter, delivered not less than 10
days before the effective date. The Registrable Securities excluded by the
managing underwriter or withdrawn from such underwriting shall be withdrawn from
such registration, and shall not be transferred in a public distribution prior
to one hundred twenty (120) days after the effective date of the registration
statement relating thereto, or such other shorter period of time as the
underwriters may require.

                  2.2.4 The Company shall have the right to terminate or
withdraw any registration initiated by it under this Section prior to the
effectiveness of such registration whether or not the holders of Registrable
Securities have elected to include securities in such registration.

         2.3 Expenses of Registration. All Registration Expenses shall be borne
by the Company. Unless otherwise stated herein, all Selling Expenses relating to
securities registered on behalf of the holders of Registrable Securities shall
be borne by the holders of Registrable Securities.

         2.4 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will keep the holders of Registrable Securities advised in writing
as to the initiation of each registration, qualification and compliance and as
to the completion thereof. At its expense, the Company will:

                  2.4.1 Prepare and file with the Commission a registration
statement with respect to such securities and use its commercially reasonable
efforts to cause such registration statement to become and remain effective
until the distribution described in such registration statement has been
completed;

                  2.4.2 Furnish to each underwriter such number of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as such underwriter
may reasonably request in order to facilitate the public sale of the Shares by
such underwriter, and promptly furnish to each underwriter and the holders of
Registrable Securities notice of any stop-order or similar notice issued by the
Commission or any state agency charged with the regulation of securities, and
notice of any NASDAQ or securities exchange listing; and

                  2.4.3 Cause the Shares to be listed on the NASDAQ small-cap
market or a securities exchange on which the Common Stock is approved for
listing.

         2.5      Indemnification.

                  2.5.1 To the extent permitted by law, the Company will
indemnify each holder of Registrable Securities, each of its officers and
directors and partners, and each person controlling such holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Agreement, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages or liabilities (or actions in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened,
to the extent such expenses, claims, losses, damages or liabilities arise out of
or are based on any untrue statement (or alleged untrue statement) of a material
fact contained in any registration statement, prospectus, offering circular or
other similar document, or any amendment or supplement thereto, incident to any
such registration, qualification or compliance, or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, or any violation by the Company of the
Securities Act or any rule or regulation promulgated under the Securities Act
applicable to the Company in connection with any such registration,
qualification or compliance, and the Company will reimburse each holder of
Registrable Securities, each of its officers and directors and partners, and
each person controlling each holder of Registrable Securities, each such
underwriter and each person who controls any such



                                      -4-
<PAGE>   5

underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action; provided, however, that the indemnity contained
herein shall not apply to amounts paid in settlement of any claim, loss, damage,
liability or expense if settlement is effected without the consent of the
Company (which consent shall not unreasonably be withheld); provided, further,
that the Company will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arising out of or is based on any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to the
Company by a holder of Registrable Securities, such controlling person or such
underwriter specifically for use therein; provided, however, that the indemnity
contained herein shall not apply to amounts paid in settlement of any claim,
loss, damage, liability, or expense if settlement is effected without the
consent of such holder of Registrable Securities (which consent shall not be
unreasonably withheld). Notwithstanding the foregoing, insofar as the foregoing
indemnity relates to any such untrue statement (or alleged untrue statement) or
omission (or alleged omission) made in the preliminary prospectus but eliminated
or remedied in the amended prospectus on file with the Commission at the time
the registration statement becomes effective or in the final prospectus filed
with the Commission pursuant to the applicable rules of the Commission or in any
supplement or addendum thereto, the indemnity agreement herein shall not inure
to the benefit of any underwriter if a copy of the final prospectus filed
pursuant to such rules, together with all supplements and addenda thereto, was
not furnished to the person or entity asserting the loss, liability, claim or
damage at or prior to the time such furnishing is required by the Securities
Act.

                  2.5.2 To the extent permitted by law, each holder of
Registrable Securities will, if securities held by such holder are included in
the securities as to which such registration, qualification or compliance is
being effected pursuant to terms hereof, indemnify the Company, each of its
directors and officers, each underwriter, if any, of the Company's securities
covered by such a registration statement, each person who controls the Company
or such underwriter within the meaning of Section 15 of the Securities Act, and
each other person selling the Company's securities covered by such registration
statement, each of such person's officers and directors and each person
controlling such persons within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) by such holder of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
such holder of Registrable Securities of any rule or regulation promulgated
under the Securities Act applicable to holders of Registrable Securities and
relating to action or inaction required of holders of Registrable Securities in
connection with any such registration, qualification or compliance, and will
reimburse the Company, such other persons, such directors, officers, persons,
underwriters or control persons for any legal or other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by such holder of Registrable Securities specifically
for use therein; provided, however, that the indemnity contained herein shall
not apply to amounts paid in settlement of any claim, loss, damage, liability or
expense if settlement is effected without the consent of such holder of
Registrable Securities (which consent shall not be unreasonably withheld).
Notwithstanding the foregoing, the liability of such Holder of Registrable
Securities under this Subsection 2.5.2 shall be limited in an amount equal to
the net proceeds from the sale of the Shares sold by such holder of Registrable
Securities, unless such liability arises out of or is based on willful conduct
by such holder of Registrable Securities. In addition, insofar as the foregoing
indemnity relates to any such untrue statement (or alleged untrue statement) or
omission (or alleged omission) made in the preliminary prospectus but eliminated
or remedied in the amended prospectus on file with the Commission at the time
the registration statement becomes effective or in the final prospectus filed
pursuant to applicable rules of the Commission or in any supplement or addendum
thereto, the indemnity agreement herein shall not inure to the benefit of the
Company or any underwriter, if a copy of the final prospectus filed pursuant to
such rules, together with all supplements and addenda thereto, was not furnished
to the person or entity asserting the loss, liability, claim or damage at or
prior to the time such furnishing is required by the Securities Act.

<PAGE>   6

                  2.5.3 Notwithstanding Sections 2.5.1 and 2.5.2, each party
entitled to indemnification under this Section (the "Indemnified Party") shall
give notice to the party required to provide indemnification (the "Indemnifying
Party") promptly after such Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought, and shall permit the Indemnifying Party to
assume the defense of any such claim or any litigation resulting therefrom,
provided that counsel for the Indemnifying Party, who shall conduct the defense
of such claim or litigation, shall be approved by the Indemnified Party (whose
approval shall not unreasonably be withheld), and the Indemnified Party may
participate in such defense at such party's expense, and provided further that
the failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Agreement unless
the failure to give such notice is materially prejudicial to an Indemnifying
Party's ability to defend such action and provided further, that the
Indemnifying Party shall not assume the defense for matters as to which there is
a conflict of interest or as to which the Indemnifying Party is asserting
separate or different defenses, which defenses are inconsistent with the
defenses of the Indemnified Party. No Indemnifying Party, in the defense of any
such claim or litigation, shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation. No Indemnified Party shall consent to entry of any
judgment or enter into any settlement without the consent of each Indemnifying
Party.

                  2.5.4 If the indemnification provided for in this Section is
unavailable to an Indemnified Party in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and all shareholders offering
securities in the offering (the "Selling Security Holders") on the other from
the offering of the Company's securities, or (ii) if the allocation provided by
clause "(i)" above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
"(i)" above but also the relative fault of the Company on the one hand and the
Selling Security Holders on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and the Selling Security Holders on the other
shall be the net proceeds from the offering (before deducting expenses) received
by the Company on the one hand and the Selling Security Holders on the other.
The relative fault of the Company on the one hand and the Selling Security
Holders on the other shall be determined by reference to, among other things,
whether the untrue (or alleged untrue) statement of material fact (or the
omission) or alleged omission to state a material fact relates to information
supplied by the Company or by the Selling Security Holders and the parties'
relevant intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Selling Security Holders
agree that it would not be just and equitable if contribution pursuant to this
Section were based solely upon the number of entities from whom contribution was
requested or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section. The amount paid
or payable by an Indemnified Party as a result of the losses, claims, damages
and liabilities referred to above in this Section shall be deemed to include any
legal or other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or claim, subject to
the provisions hereof. Notwithstanding the provisions of this Section, no
Selling Shareholder shall be required to contribute any amount or make any other
payments under this Agreement which in the aggregate exceed the proceeds
received by such Selling Shareholder. No person guilty of fraudulent
misrepresentation (within the meaning of the Securities Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent
misrepresentation.

         2.6      Certain Information.

                  2.6.1 The holders of Registrable Securities agree, with
respect to any Registrable Securities included in any registration, to furnish
to the Company such information regarding such holder, the Registrable
Securities and the distribution proposed by the such holder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to herein.



                                      -6-
<PAGE>   7

                  2.6.2 The failure of the holder of Registrable Securities to
furnish the information requested pursuant to Section 2.6.1 shall not affect the
obligation of the Company to the other Selling Security Holders who furnish such
information unless, in the reasonable opinion of counsel to the Company or the
underwriters, such failure impairs or may impair the legality of the
Registration Statement or the underlying offering.

         2.7      Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of Restricted Securities (used herein as defined in Rule
144 under the Securities Act) to the public without registration, the Company
agrees to use its best lawful efforts to:

                  2.7.1 Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times during which the Company is subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act");

                  2.7.2 File with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Exchange Act (at all times during which the Company is subject to such reporting
requirements); and

                  2.7.3 So long as any holder of Registrable Securities owns any
Restricted Securities (as defined in Rule 144 promulgated under the Securities
Act), to furnish to such holder forthwith upon request a written statement by
the Company as to its compliance with the reporting requirements of said Rule
144 and with regard to the Securities Act and the Exchange Act (at all times
during which the Company is subject to such reporting requirements), a copy of
the most recent annual or quarterly report of the Company, and such other
reports and documents of the Company and other information in the possession of
or reasonably obtainable by the Company as such holder of Registrable Securities
may reasonably request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any such securities without
registration.

         2.8      Transferability. The rights conferred by this Agreement shall
be freely transferable to a recipient of Registrable Securities.

         2.9      Governing Law. THIS AGREEMENT SHALL BE GOVERNED IN ALL
RESPECTS BY THE LAWS OF THE STATE OF TEXAS.

         2.10     Entire Agreement; Amendment. This Agreement constitutes the
full and entire understanding and agreement between the parties with regard to
the subject hereof. This Agreement, or any provision hereof, may be amended,
waived, discharged or terminated upon the written consent of the Company and the
Purchaser.

Stock, US $.01 of which 60,936,573 are issued and outstanding as of December 1,
1999, and 50,000,000 shares of Preferred Stock, US $.01, of which 3,719,409
shares are issued and outstanding as of December 1, 1999.

                  (d) Valid Issuance of Securities. Upon receipt of the
consideration from Coastal as described herein, the Stock will be duly
authorized, validly issued, fully paid, and nonassessable.

                  (e) Binding Obligations. This Agreement constitutes the
binding obligation of the Company, enforceable in accordance with its terms,
except to the extent that the enforceability thereof may be limited by
bankruptcy, insolvency or other similar laws affecting creditors' rights
generally or under general principles of equity.

                  (f) Financial Condition. The audited annual consolidated
Financial Statements of the Company and its Consolidated Subsidiaries for its
most recently ended fiscal year ended December 31, 1998 (the "1998 Financial
Statements"), and the unaudited consolidated interim Financial Statements of the
Company and its Consolidated Subsidiaries for its most recently ended fiscal
quarter (for which such annual or quarterly Financial Statements are available),
which have been delivered to Coastal, are complete and correct in all material
respects, have been prepared in accordance with GAAP, consistently applied, and
present fairly the consolidated financial condition and results of the
operations of the Company and its Consolidated Subsidiaries as at the date or
dates and for the period or periods stated (subject only to normal year-end
audit adjustments with respect to such unaudited interim statements). No
material adverse change has since occurred in the consolidated financial
condition or operations of the Company and its Consolidated Subsidiaries, except
as otherwise disclosed to Coastal.

                  (g) Defaults. Except as disclosed to Coastal, neither the
Company nor any Subsidiary is in Default (in any respect which materially and
adversely affects the consolidated business, Property, operations or


                                      -7-
<PAGE>   8


financial condition of the Company and its Consolidated Subsidiaries) under any
instrument evidencing borrowed money to which the Company or a Subsidiary is a
party or by which it is bound.

                  (h) Tax Returns and Payments. The Company has (i) filed all
tax returns which it is required to file, where the failure to file such returns
would have a Material Adverse Effect on the consolidated financial condition or
operations of the Company and its Consolidated Subsidiaries, and (ii) paid, or
has provided adequate reserves for the payment of all material federal and state
income taxes applicable for all prior fiscal years and for the current fiscal
year down to the date hereof.

                  (i) Litigation Representation. Except as disclosed to Coastal
or in the Public Documents, there is no litigation (including without
limitation, derivative actions), arbitration proceedings or governmental
proceedings pending or, to the knowledge of the Company, threatened against it
or any Subsidiary which involves the reasonable probability of a judgment not
covered by insurance or which would have a Material Adverse Effect on the
Company and its Consolidated Subsidiaries.

                  (j) Compliance with ERISA. The Company and each of its
Subsidiaries are in compliance in all material respects with ERISA. Neither the
Company nor any of its Subsidiaries has any material liability under any type of
Plan. No reportable event, as set forth in Section 4043(b) of ERISA, has
occurred and is continuing with respect to any Plan which results in any
material liability to the PBGC.

                  (k) Environmental Matters. Neither the Company nor any
Subsidiary (i) has received written notice, nor has any officer of the Company
otherwise learned, of any claim, demand, action, event, condition, report or
investigation indicating or concerning any potential or actual liability which
individually or in the aggregate would have a Material Adverse Effect, arising
in connection with: (x) any noncompliance with or violation of the requirements
of any applicable federal, state or local environmental health and safety
statutes and regulations or (y) the release or threatened release of any toxic
or hazardous waste, substance or constituent, or other substance into the
environment, (ii) to the best of Company's knowledge, has any liability in
connection with the release or threatened release of any toxic or hazardous
waste, substance or constituent, or other substance into the environment which
in the aggregate would have a Material Adverse Effect, (iii) has received notice
of any federal or state investigation evaluating whether any remedial action is
needed to respond to a release or threatened release of any toxic or hazardous
waste, substance or constituent or other substance into the environment for
which the Company or any Material Subsidiary is or may be liable where the
taking or the failure to take such remedial action would have a Material Adverse
Effect, or (iv) has received notice that the Company or any Material Subsidiary
is or may be liable to any Person under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section
9601 et seq. ("CERCLA"), or any analogous state law, the failure to comply with
which would have a Material Adverse Effect. To the best of the Company's
knowledge, the Company and each Material Subsidiary is in compliance in all
material respects with the financial responsibility requirements of federal and
state environmental laws to the extent applicable, including, without
limitation, those contained in 40 C.F.R., parts 264 and 265, subpart H, and any
analogous state law, the failure to comply with which would have a Material
Adverse Effect.

                  (l) Compliance with Applicable Laws. Neither the Company nor
any Material Subsidiary is in default with respect to any judgment, order, writ,
injunction, decree or decision of any governmental authority, which default
would have a Material Adverse Effect. To the best of the Company's knowledge,
the Company and each Subsidiary is in compliance with all applicable statutes,
rules and regulations, including ERISA, of all governmental authorities, and
(except as disclosed to Coastal) of every exchange on which the Capital Stock of
the Company is listed, a violation of which would have a Material Adverse
Effect. In addition and not in limitation of the foregoing, the transactions
contemplated by this Agreement will not (i) violate any NASDAQ rules applicable
to the Company or, singly or together with other events, cause the Common Stock
to cease to be authorized for quotation on NASDAQ; (ii) constitute a "change of
control" for purposes of NASDAQ Stock Market Rule 4310(c)(25); or (iii) violate
NASDAQ Stock Market Rule 4310(c)(21) regarding voting rights. In addition and
not in limitation of the foregoing, the acquisition of the Common Stock Units
will not require shareholder approval under the laws, rules and regulations of
the SEC, NASDAQ or any provision of the Certificate of Incorporation or By-Laws
of the Company; and the acquisition of the Common Stock Units will not require
the review of the Federal Trade Commission or the Antitrust Division of the U.S.
Department of Justice under the Hart-Scott-Rodino Antitrust Improvements Act of
1976.

                  (m) Patents, Licenses, Etc. Except as disclosed to Coastal,
the Company warrants that it has all right and title to, and has maintained and
caused each Subsidiary to maintain in full force and effect, all material
licenses, copyrights, patents, permits, applications, reports, authorizations,
easements and other rights as are necessary for the conduct of the business of
Company and its Consolidated Subsidiaries, where the termination of such rights
would have a Material Adverse Effect.

                  (n) Disclosure. Each of Company's representations in the
Transaction Documents are true, complete and accurate in all material respects.
Company has disclosed all material facts of which it has knowledge and regarding
the transaction contemplated by this Agreement. Company has not failed to
disclose to Coastal any material fact necessary in order to make any statement
made, in light of the circumstances under which made, not misleading.

         Section 6.02 By Coastal. Coastal represents and warrants to the Company
that:

                  (a) Organizational Status; Authority; Enforceability; No
conflicts; etc. Coastal is a trust, duly formed under the laws of the State of
Texas, and has all requisite power and authority to enter into and perform its
obligations under this Agreement. The execution and delivery of this Agreement
and the consummation of the transactions hereunder have been duly authorized by
all required action. This Agreement has been duly executed and delivered on
behalf of Coastal and is a legal, valid and binding obligation, enforceable in
accordance with its terms, subject to applicable bankruptcy and insolvency laws
and general principles of equity. This Agreement does not conflict with any of
Coastal's organizational documents or any other contract or agreement to which
it is a party, or any law, rule or regulation binding on or applicable to
Coastal.

                  (b) Investment Purpose. The securities to be issued to Coastal
under or as contemplated in this Agreement are being acquired, or will be
acquired, for investment for its own account, and not with a view to, or for
resale in connection with, any distribution of securities within the meaning of
the Securities Act. No securities may be sold, transferred, or otherwise
disposed of without registration under the Securities Act and any applicable
state securities laws, except under any exemption from those laws.

                  (c) Accredited Investor Status. Coastal is an "accredited
investor" as that term is defined in Rule 501(a) of Regulation D promulgated
under the Securities Act.

                  (d) No Litigation. There are no claims, actions, suits,
proceedings or investigations pending, or, to the knowledge of Coastal
threatened against it, which, if adversely resolved, would materially impair its
ability to perform its obligations under this Agreement or which challenge the
legality of, or seek to enjoin, restrain or prohibit the consummation of the
transactions contemplated by this Agreement.

                  (e) Reliance on Exemptions. Coastal understands that the
Common Stock Units, including the Common Stock, the Warrants and the Warrant
Shares, are being issued to it in reliance on specific exemptions from the
registration requirements of United States federal and state securities laws and
that the Company is relying in part upon the truth and accuracy of, and
Coastal's compliance with, the representations and warranties of Coastal in
order to determine the availability of such exemptions and the eligibility of
Coastal to acquire the Common Stock Units, including the Common Stock, the
Warrants and the Warrant Shares.

                  (f) Information. Coastal and its advisors, if any, have been
afforded the opportunity to ask questions of the Company, including its
management. Coastal has sought such accounting, legal and tax advice as it has
considered necessary to make an informed investment decision with respect to its
acquisition of the Common Stock Units, including the Common Stock, the Warrants
and the Warrant Shares. Coastal acknowledges that:

                           (i) it has access to copies of (and acknowledges that
                  the Company has offered to provide, upon request, copies of)
                  the Company's filings with the Securities Exchange Commission
                  (collectively, the "Public Documents");

                           (ii) it understands that the acquisition of Common
                  Stock Units entails various risks including, but not limited
                  to, those outlined in the Public Documents and in this
                  Agreement, and has determined that the Common Stock Units are
                  a suitable investment and that at this time it could bear a
                  complete loss of its investment; and


                                      -9-
<PAGE>   10


                           (iii) any information which Coastal has heretofore
                  represented or furnished to the Company with respect to its
                  financial sophistication is correct and complete as of the
                  date of this Agreement.

                  (g) No Governmental Review. Coastal understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Common Stock
Units, including the Common Stock, the Warrants and the Warrant Shares, or the
fairness or suitability of the investment in the Common Stock Units, including
the Common Stock, the Warrants and the Warrant Shares, nor have such authorities
passed upon or endorsed the merits of the offering.

                  (h) Transfer or Resale. Coastal understands that except as
provided herein: (i) the Common Stock Units, including the Common Stock, the
Warrants and the Warrant Shares, have not been registered under the Securities
Act or any state securities laws, and may not be offered for sale, sold,
assigned or transferred unless (A) subsequently registered, (B) Coastal shall
have delivered to the Company an opinion of counsel, in a generally acceptable
form, to the effect that the Common Stock Units, including the Common Stock, the
Warrants and the Warrant Shares, to be sold, assigned or transferred may be
sold, assigned or transferred pursuant to an exemption from such registration,
or (C) Coastal provides the Company with reasonable assurance that such Common
Stock Units, including the Common Stock, the Warrants and the Warrant Shares,
can be sold, assigned or transferred pursuant to Rule 144 promulgated under the
Securities Act, as amended (or a successor rule thereto)("Rule 144"); and (ii)
any sale of the Common Stock Units, including the Common Stock, the Warrants and
the Warrant Shares, made in reliance on Rule 144 may be made only in accordance
with the terms of Rule 144 and further, if Rule 144 is not applicable, any
resale of the Common Stock Units, including the Common Stock, the Warrants and
the Warrant Shares, under circumstances in which the seller (or the person
through whom the sale is made) may be deemed to be an underwriter (as that term
is defined in the Securities Act) may require compliance with some other
exemption under the Securities Act or the rules and regulations of the
Securities and Exchange Commission thereunder; and (iii) except as expressly
provided in this Agreement or the Registration Rights Agreement, neither the
Company nor any other person is under any obligation to register such shares
under the Securities Act or any state securities laws or to comply with the
terms and conditions of any exemption thereunder.

with which the independent public accountants concur, and subject to normal
year-end audit adjustments with respect to the unaudited quarterly statements
described in Section 7.01(b) hereof.

                  (d) Actions. Notice of all actions, suits, claims, proceeding,

Property (including applicable statutes, regulations, orders and restrictions
relating to environmental standards and controls).

         Section 7.03 Insurance. The Company shall maintain, and cause each

thereof, all as in the judgment of the Company or such Material Subsidiary may
be necessary, so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company or any Material Subsidiary
from discontinuing the use, operation or maintenance of any such Property, or
disposing of any such Property, if such discontinuance or disposal is, in the
judgment of the Board of Directors or the board of directors, board of trustees
or managing partners of the Material Subsidiary concerned, or of any officer (or
other agent employed by the Company or any of its Material Subsidiaries) of the
Company or such Material Subsidiary having managerial responsibility for any

the Company shall maintain and cause each Material Subsidiary to maintain, in
