                                    AGREEMENT

                                 I. DEFINITIONS

         Section 1.01 Defined Terms. As used in this agreement, the following
capitalized terms shall have the meanings respectively assigned to them below,

ascribed to them in the Purchase Agreement and the Notes.


         "Affiliate" means as to any Person or any other Person, directly or
indirectly, controlling or controlled by or under direct or indirect common
control of such Person. For purposes of this definition "control," when used
with respect to any Person, means the power to direct the management and
policies of such Person, directly or indirectly, whether through the ownership
of voting securities, by contract or otherwise, and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.

         "Business Day" shall mean any day that the banks located in the State
of Texas are open to conduct business.

         "Common Stock" shall mean the common stock, no par value per share, of
the Company.

         "Common Stock Equivalents" shall mean all options, warrants (including,
without limitation, the Warrants), securities of any kind (including, without
limitation, securities convertible into or exchangeable or exercisable for
Common Stock) and other rights (in each case whether now existing or hereafter
issued or arising) to acquire from the Company shares of Common Stock (without
regard to whether such options, warrants, securities and other rights are then
exchangeable, exercisable or convertible in full, in part or at all).

         "Company" shall have the meaning set forth in the preamble.

         "Dividend" means, as to any Person, any declaration or payment of any
dividend or distribution (other than a dividend of Common Stock) on, or the
making of any pro rata distribution, loan, advance, or investment to, any shares
of capital stock of such Person.

         "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, and the rules and regulations promulgated thereunder, and any successor
provisions thereto.

         "Exercise Price" shall mean $0.20 per share. The Exercise Price and the

<PAGE>   4

         "Expiration Period" means January 25, 2005.

         "Exercise Quantity" shall mean the number of shares of Common Stock,
determined from time to time, taking into account all shares of Common Stock
theretofore issued upon exercise of the Warrants, required to be issued by the
Company to the holders of the Warrants. Exercise Quantity may be adjusted from
time to time pursuant to the provisions of the Warrants and this Agreement.

         "Fair Value" as of a particular date shall mean the closing asked price
of the Common Stock as reported on a national securities exchange or on the
NASDAQ SmallCap, National Market System or OTC Bulletin Board Service
(collectively, and as applicable, "NASDAQ") or, if a last asked quotation is not
available for the Common Stock, the last sale price of the Common Stock as
reported by NASDAQ, or if not so reported, as listed in the National Quotation
Bureau, Inc.'s "Pink Sheets." If such quotations are unavailable, or with
respect to other appropriate security, property, assets, business or entity,
"Fair Value" shall mean the fair value of such item as determined by mutual
agreement reached by the Holder and the Company or, in the event the parties are
unable to agree, an opinion of PriceWaterhouseCoopers, LLP ("PWC") in accordance
with the following procedure. In the case of any event which gives rise to a
requirement to determine "Fair Value" pursuant to this Agreement, the Company
shall notify the Holders of such event as promptly as practicable, but in any
event within ten (10) calendar days following such event and if the procedures
contemplated herein in connection with determining Fair Value have not been
complied with fully, then any such determination of Fair Value for any purpose
of this Agreement shall be deemed to be preliminary and subject to adjustment
pending full compliance with such procedures.

         Upon the occurrence of an event requiring the determination of Fair
Value, the Company shall give the Holder(s) of the Warrants notice of such
event, and the Company and the Holders shall engage in direct good faith
discussions to arrive at a mutually agreeable determination of Fair Value. In
the event the Company and the Holder(s) are unable to arrive at a mutually
agreeable determination within ten (10) days of the notice, the Company and the
Holder(s) of the Warrants (who, if more than one, shall agree among themselves
by a majority) shall retain PWC. Such firm shall determine the Fair Value of the
security, property, assets, business or entity, as the case may be, in question
and deliver its opinion in writing to the Company and to such Holder within
thirty (30) days of its retention. Each of the Company and the Holders (as a
group) shall submit to PWC their proposed determination of Fair Value, and any
other supporting documentation reasonably requested by PWC. In no event shall
the marketability, or lack thereof, or lack of registration of a security be a
factor in determining the "Fair Value" of such security. The determination so
made shall be conclusive and binding on the Company and such Holder(s), absent
clear and manifest error. The fees and expenses of PWC pursuant to this
provision shall be borne by the Company in advance. In the event the Company
fails to pay such fees, or the retainer or deposit requested by such independent
certified public accounts' firm,



                                       3
<PAGE>   5

within 10 days of the acceptance by PWC (conditional or unconditional) of such
engagement, then the Holders' proposed determination of Fair Value shall be
conclusive and binding upon the Company.

         "Holder" or "Holders" shall mean the Person(s) then registered as the
owners of the Warrants or Warrant Securities, as the case may be, on the books
and records of the Company.

         "Person" shall mean any individual, corporation, partnership, limited
liability company, association, joint-stock company, trust, estate,
unincorporated organization, joint venture, court or governmental or political
subdivision or agency thereof.

other business entity of which more than fifty percent (50%) of the total voting
power of all classes of the outstanding voting stock or other indicia of
ownership is owned, directly or indirectly, by such Person or by one or more
other Subsidiaries of such Person or by such Person and one or more Subsidiaries
thereof, (ii) any partnership (a) the sole general partner or the managing
general partner of which is such Person or a Subsidiary of such Person or (b)
the only general partners of which are such Person or one or more Subsidiaries
of such Person (or any combination thereof) and (iii) any other Person not
described in clauses (i) and (ii) above in which such Person, or one or more
other Subsidiaries of such Person or such Person and one or more other
Subsidiaries thereof, directly or indirectly, owns 50% ownership and the power,
whether by such ownership interest, pursuant to a written contract or agreement
or otherwise, to direct the policies and management or the financial and other
affairs thereof.

         "Warrant Securities" shall mean the shares of Common Stock purchasable
or purchased from time to time under the Warrants or acquirable or acquired upon
any transfer of any such securities, together with all additional securities
receivable or received in payment of Dividends or distributions on or splits of
those securities or receivable or received as a result of adjustments provided

               III. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

qualified to do business as a foreign corporation and is in good standing under
the laws of each state or other jurisdiction where the failure to be so

to be qualified or licensed therein.

         (b) The execution and delivery of this Agreement and the Warrants have
been duly and properly authorized by all requisite corporate action of the
Company and its board of directors, and no consent of any other Person is

this Agreement and the Warrants that has not been obtained. The Company has the
full legal right, power and authority to execute and deliver this Agreement and
the Warrants and to perform its obligations hereunder and thereunder. When

accordance with the terms hereof, for the consideration expressed herein, shall
be duly and validly issued and outstanding, fully paid and nonassessable, and
will be issued in compliance with all applicable federal and state securities or

<PAGE>   8

the Warrants or to perform any obligation hereunder or thereunder (including,
without limitation, issuance of the Warrant Securities). Neither the execution
or delivery of this Agreement or the Warrants, nor compliance therewith
(including, without limitation, issuance of the Warrant Securities), will
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, or result in any violation of, or result in the
creation of any material lien upon any assets or properties of the Company
under, or require any consent, approval, or other action by, notice to or filing
with any court or governmental agency or division pursuant to the Articles of
Incorporation or Bylaws of the Company, as currently in effect, any award of any
arbitrator, or any agreement, instrument or law to which the Company is subject
or by which it or its assets or properties is bound.

         (e) The Warrants are, and the Warrant Securities will be, issued by the
Company to the Investors in a transaction exempt from registration and
qualification under the applicable federal and state securities and blue sky

         Section 4.01 Covenants of the Company. The Company hereby covenants and
agrees that, during the term of this Agreement, unless Holders of outstanding
Warrants evidencing a majority of the Warrants agree otherwise in writing,

         (a) Each of the Warrant Securities issued and delivered upon the
exercise of the Warrants and payment of the Exercise Price will be duly and
validly authorized and issued, will be fully paid and nonassessable, and will
not be subject to any unpaid tax of the Company or any lien imposed on or
created by the Company, whether respecting their issuance to and purchase by the
Holder of the Warrants or otherwise. The Company will take all such actions as
may be necessary to assure that all such Warrant Securities may be so issued
without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange or quotation system upon which
such Warrant Securities may be listed.

         (b) The Company shall reserve and at all times keep available for
issuance an authorized number of shares of Common Stock or Warrant Securities
sufficient to permit the full and immediate exercise of the Warrants and the
full and immediate exercise, exchange and conversion of all other securities,

(i) all annual, quarterly and monthly financial statements made available by the
Company to its shareholders, (ii) all reports, notices and proxy or information
statements sent or made available generally by the Company to its shareholders,

relevant state authorities or any securities exchange, securities quotation
system or other self-regulatory organization.

         (e) The Company agrees that to the extent reasonably necessary to
permit the Holders to sell shares of the Common Stock in accordance with and in
reliance on Rule 144, and for so long as such shares are owned by the Holders
and such shares are not registered for resale under the Securities Act, the
Company will make and keep public information available within the meaning of
Rule 144 at all times from and after the Closing Date, and file with the SEC in
a timely manner all reports and other documents required of the Company under
the Securities Act and the Exchange Act.

(f) The Company shall cooperate with the Holder(s) of the Warrants and the
Warrant Securities in supplying such information as may be reasonably necessary
for the Holder(s) to complete and file any information or other reporting forms
from time to time required by the Commission, relevant state authorities or any
securities exchange, securities quotation system or other self-regulatory
organization, including, without limitation, information pertaining to or
required for the availability of any exemption from the securities laws for the
sale, transfer or other disposition of the Warrants or any of the Warrant
Securities.

         Section 4.02 Indemnification.

         (a) The Company agrees to defend, indemnify and hold harmless, to the
full extent permitted by law, Investors and each other Holder of the Warrants,
this Agreement, or any Warrant Security purchased hereunder, any underwriter(s),
and their respective directors, officers, employees, attorneys and agents, as
well as each other Person (if any) controlling any of the foregoing Persons
within the meaning of Section 15 of the Securities Act, or Section 20 of the
Exchange Act, from and against any and all claims, liabilities, losses and
expenses (including, without limitation, the reasonable disbursements, expenses
and fees of their respective attorneys, accountants and experts) that may be
imposed upon, incurred by, or asserted against any of them, any of their
respective directors, officers, employees, attorneys and agents, or any such
control Person, under the Securities Act, the Exchange Act or any other statute
or at common law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof), arise out of or are related directly or indirectly
to (i) the breach of any of the representations, warranties and/or covenants of
the Company contained herein, or (ii) any alleged untrue



                                       8
<PAGE>   10

statement of any material fact contained, on the effective date thereof, in any
registration statement under which such securities are or were registered under
the Securities Act or the Exchange Act, or in any preliminary prospectus or
final prospectus related thereto, or any amendment or supplement thereto, or any
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and shall reimburse
such Persons for any legal or any other expenses reasonably incurred by such
Persons in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company shall not be
liable in any such case to the extent that any such loss, claim or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in said registration statement, preliminary
prospectus, final prospectus amendment or supplement thereto incident to
registration or qualification of any Warrant Securities in reliance upon and in
strict conformity with written information furnished to the Company by such
Persons with respect to information regarding such Persons expressly for
inclusion therein. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of any such indemnified
Person, and shall survive the transfer of such securities by such Person.
Promptly after receipt of notice of the commencement of any action in respect of
which indemnity may be sought against the Company, the Company shall assume the
defense of such action (including the employment of counsel, who shall be
reasonably satisfactory to the party seeking indemnity hereunder) and the
payment of expenses insofar as such action shall relate to any alleged liability
in respect of which indemnity may be sought against the Company. If the Company
assumes the defense of such action, (i) no compromise or settlement of such
claims may be effected by the Company without the indemnified party's consent
unless (1) there is no finding or admission of any violation of law, regulation,
rule or order or any violation of the rights of any other person or entity and
no effect on any other claims that may be made against the indemnified party,
and (2) the sole relief provided is monetary damages that are paid in full by
Company; and (ii) the indemnified party will have no liability with respect to
any compromise or settlement of such claims effected without its consent. If
notice is given to the Company of the commencement of any action and the Company
does not, within ten days after the indemnified party's notice is given to the
Company, give notice to the indemnified party of its election to assume the
defense of such action, the Company will be bound by any determination made in
such action or any compromise or settlement effected by the indemnified party.

         Section 4.03 Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a claim or
action may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, or if an indemnified party determines that there are defenses
available to it that the Company cannot assert on behalf of the indemnified
party or not being raised by the Company after the indemnified party has given
the Company notice of such defense, or if the indemnified party reasonably
determines that there is a conflict of interest between the Company and the
indemnified party in the claim or action, the indemnified party



                                       9
<PAGE>   11

may, by notice to the Company, assume the exclusive right to defend, compromise,
or settle such claim or action, and the Company will be bound by any
determination of a claim or action so defended or any compromise or settlement
effected.

                                V. ANTIDILUTION

         Section 5.01 No Dilution or Impairment: Adjustments.

         (a) Prohibited Actions. So long as any Warrants are outstanding, the
Company will not avoid or seek to avoid the observance or performance of any of
the terms of this Agreement or the Warrants or impair the ability of the
Holder(s) to realize the full intended economic value thereof, but will at all
times in good faith assist in the carrying out of all such terms, and of the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the Holder(s) of the Warrants against dilution or other
impairment.

         (b) Adjustment of Exercise Price in the Event of Certain Issuances of
Common Stock or Common Stock Equivalents. In case the Company shall at any time
(i) issue or sell Common Stock or Common Stock Equivalents (by merger otherwise)
for less than $0.125 (as adjusted for stock divisions, dividends, combinations,
recapitalizations and reclassifications) (other than (A) delivery of shares of
Common Stock upon exercise of the Warrants, and (B) any Common Stock Equivalents
issued and outstanding on the date hereof), or (ii) issue Common Stock or Common
Stock Equivalents by way of a Dividend or other distribution on any stock of the
Company or effect a forward stock split of the outstanding shares of Common
Stock, the Company shall first obtain approval from the Board of Directors
consisting of at least one representative of the Investors pursuant to the
Shareholders Agreement, and the Exercise Price then in effect shall be
proportionately decreased (on the date of such issuance, sale or split) so that
the new Exercise Price shall be equal to the product of (x) the former Exercise
Price and (y) the lesser of (i) one or (ii) the following fraction:

                    The number of shares of Common Stock and
     Common Stock Equivalents outstanding immediately prior to such issuance
                    The number of shares of Common Stock and
      Common Stock Equivalents outstanding immediately after such issuance

and the Exercise Quantity purchasable upon exercise of the Warrants immediately
prior thereto shall be adjusted so that the new Exercise Quantity shall be equal
to the product of (x) the former Exercise Quantity and (y) the following
fraction:

         (c) Company to Prevent Dilution. In any case at any time or from time
to time conditions arise by reason of action taken by the Company which are not
adequately covered by the provisions of this Article V, and which might
adversely affect the rights of the Holders under any provision of this
Agreement, unless the adjustment necessary shall be agreed upon by the Company
and the Holders, the Board of Directors of the Company shall appoint PWC,
acceptable to the Holders, who at the Company's expense shall give their opinion
upon the adjustment, if any, on a basis consistent with the standards
established in the other provisions of this Article V, necessary with respect to
the Exercise Price and the Exercise Quantity, so as to preserve, without
dilution, the rights of the Holders. Upon the receipt of such opinion, the
Company's Board of Directors shall forthwith make the adjustments described
therein; provide, however, that no such adjustment shall be made to increase the
Exercise Price or decrease the Exercise Quantity.

         (d) Reorganization; Asset Sales; Etc. In case of (i) any capital
reorganization or any reclassification of the capital stock of the Company, (ii)
any consolidation or merger of the Company or any Subsidiary with or into
another Person, (iii) the disposition or transfer of assets of the Company other
than in the ordinary course of the Company's business, (iv) any Dividend or
other distribution to the holders of capital stock of the Company in the form of
any asset, including without limitation securities of the Company, or (v) the
dissolution, liquidation or winding up of the Company, the Holders shall
thereafter be entitled to purchase (and it shall be a condition to the
consummation of any such transaction or event that appropriate provision shall
be made so that such Holders shall thereafter be entitled to purchase) the kind
and amount of shares of stock and other securities and property receivable in
such transaction by a holder of the number of shares of Common Stock of the
Company into which this Agreement entitled the Holders to purchase immediately
prior to such capital reorganization, reclassification of capital stock,
non-surviving combination or disposition; and in any such case appropriate
adjustments shall be made in the application of the provisions of this Article V
with respect to rights and interests thereafter purchasable upon the exercise of
a Warrant.

         (e) Adjustment Statement. Whenever the Exercise Price or Exercise
Quantity is adjusted as herein provided, the Company shall, within ten days
following the consummation of the event triggering such adjustment, deliver to
the Holders a statement signed by the President of the Company and by its
Treasurer or Secretary stating the adjusted Exercise Price and Exercise Quantity
for which the Warrants are exercisable, determined as specified herein. The
statement shall show in detail the facts requiring such adjustment, including a
statement of the consideration received by the Company for any additional stock
issued. Irrespective of any adjustments in the Exercise Price or the Exercise
Quantity or the kind of shares purchasable upon the exercise of the Warrants,
the Warrants theretofore or thereafter issued may continue to express the same
price and number and kind of shares as are stated in the Warrants initially
issuable pursuant to this Agreement.

holders of its capital stock any additional shares of stock of any class or any
other rights; or

Company (other than a change in par value, or a change from par value to no par
value, or a change from no par value to par value, or a change resulting solely
from a subdivision of outstanding shares), or any consolidation or merger, or
any sale, transfer or other disposition of all or substantially all of its
property, assets, business and goodwill as an entirety, or the liquidation,
dissolution or winding up of the Company; or

                  (iv) The Company shall declare a Dividend upon its capital

stock dividend, distribution or subscription rights, or the date on which such
reclassification, reorganization, consolidation, merger, sale, transfer,
disposition, liquidation, dissolution, winding up, or Dividend, as the case may

successor), to conduct an audit of the computations pursuant to the terms hereof
involved in such dispute, including the financial statements or other
information upon which such computations were based. The determination of such
accounting firm shall, in the absence of manifest error, be conclusive and
binding.

contained in this Agreement are not intended and shall not be construed to

manner whatsoever any right or remedy of the



                                       14
<PAGE>   16

Holder(s) under the Company's Certificate of Incorporation, Bylaws or similar
agreements, or any other agreements between the Company and/or its affiliates
and Investors.

         Section 8.03 Reliance. Each party to this Agreement shall be entitled
to rely upon any notice, consent, certificate, affidavit, statement, paper,
document, writing or other communication reasonably believed by that party to be

or permitted hereunder shall be made in writing and be by hand-delivery or
certified mail, return receipt requested, (a) if to Holders, to the address set
forth on the signature page hereof or such other address given by Holders to the

Company, as follows:

                  MigraTEC, Inc.
                  12801 Stemmons Freeway, Suite 710
                  Dallas, Texas  75234
                  Telecopier: (972) 969-0315
                  Attn:   President

         All such notices and communications shall be deemed to have been duly
given upon delivery or attempted delivery during normal business hours.

         Section 8.05 Enforcement. The Company acknowledges that the Holders may
proceed to exercise or enforce any right, power, privilege, remedy or interest
that they may have under this Agreement or applicable law without notice, except
as otherwise expressly provided herein, without pursuing, exhausting or
otherwise exercising or enforcing any other right, power, privilege, remedy or
interest that they may have against or in respect of any other party, or any
other Person or thing, and without regard to any act or omission of such party
or any other Person. The Company's obligations hereunder, including, without
limitation the obligation to issue the Warrant Securities upon exercise of the
Warrants, are absolute and unconditional and are not subject to any abatement,
reduction, setoff, defense, counterclaim or recoupment due or alleged to be due
to, or by reason of, any past, present or future claims which the Company may
have against the Investors or any Holder, or any assignee, thereof, for any
reason whatsoever. All rights and remedies of the party hereto are cumulative of
each other and of every other right or remedy such party may otherwise have at

prejudice or impair the concurrent or subsequent exercise of other rights or
remedies.

         Section 8.06 Equitable Relief. Each party acknowledges and agrees that
it would be impossible to measure in money the damage in the event of a breach
of any of the terms and provisions of this Agreement by any party hereto, and
that, in the event of any such breach, there may not be an adequate remedy at
law, although the foregoing shall not constitute a waiver of any of the party's
rights, powers, privileges and remedies against or in respect of a breaching
party, any other person or thing under this Agreement or applicable law. It is
therefore agreed that, in addition to all other such rights, powers, privileges
and remedies that it may have, each party shall be entitled, without the
obligation to post bond, to injunctive relief, specific performance or such
other equitable relief as such party may request to exercise or otherwise
enforce any of the terms and provisions of this Agreement and to enjoin or
otherwise restrain any act prohibited thereby, and no party will urge, and each
party hereby waives, any defense that there is an adequate remedy available at
law.

         Section 8.07 Merger or Consolidation of the Company. So long as the
Warrants remains outstanding, the Company will not merge or consolidate with or
into, or sell, transfer or lease all or substantially all of its property to,

agreement, the due and punctual performance and observance of each and every
covenant and condition of this Agreement to be performed and observed by the
Company.

         Section 8.08 Interpretation; Headings, Severability.

         (a) The parties acknowledge and agree that since each party and its
counsel have had the opportunity to review and negotiate the terms and
provisions of this Agreement and have contributed to its revision, the normal
rule of construction to the effect that any ambiguities are resolved against the
drafting party shall not be employed in the interpretation of this Agreement,
and its terms and provisions shall be construed fairly as to all parties hereto
and not in favor of or against any party, regardless of which party was
generally responsible for the preparation of this Agreement.

         (b) The Section and other headings contained in this Agreement are for
reference purposes only and shall not affect the meaning or interpretation of
this Agreement.

         (c) In the event that any term or provision of this Agreement shall be
finally determined to be superseded, invalid, illegal or otherwise unenforceable
pursuant to applicable law by a governmental authority having jurisdiction and
venue, such determination shall not impair or otherwise affect the validity,
legality or enforceability: (i) by or before that authority of the remaining
terms and provisions of this Agreement, which shall be enforced as if the
superseded, invalid, illegal or otherwise unenforceable term or provision were
modified to the extent required to permit such provision to be not superseded,
invalid, illegal or unenforceable, or (ii) by or before any other authority of
any of the terms and provisions of this Agreement.

effect until the term of this Agreement has expired, and thereafter with respect
to events occurring prior thereto.

         Section 8.10 No Required Exercise. No term or provision of the Warrants
or this Agreement is intended to require, nor shall any such term or provision
be construed as requiring, any Holder of the Warrants to exercise or sell the
Warrants.

         Section 8.11 Binding Effect. This Agreement shall be binding upon and
enforceable against the parties hereto and their respective successors and
assigns.

         Section 8.12 No Waiver by Action or Course of Dealing. No course of
dealing or any delay or failure to exercise any right hereunder on the part of
any party hereto shall operate as a waiver of such right or otherwise prejudice
the rights, powers or remedies of such party.

         Section 8.13 Waiver; Modification; Amendment. Each and every
modification to and amendment of this Agreement shall be in writing and signed
by the Company, Investors (if at that time Investors is a Holder) and by the
Holders of a majority in interest of all issued and unissued Warrant Securities.

Investors (if at that time it is a Holder) and by the Holders of a majority in
interest of all issued and unissued Warrant Securities and by each party against
whom enforcement of the waiver or consent may be sought. Notwithstanding the
foregoing, no modification, amendment or waiver of any term or provision hereof
with respect to the Exercise Price, the Exercise Quantity, any terms of Article
V hereof, any of the terms of this Section 8.13 or which purports, or has the
effect of, shortening the term of any Warrants or limiting the right or ability
of a Holder thereof to exercise a Warrant shall be enforceable against a Holder
unless such Holder specifically approves, in writing, such modifications,
amendment or modification.

         Section 8.14 Entire Agreement. This Agreement and the Warrants contain
the entire agreement of the parties with respect to the Warrants and supersede
all other representations, warranties, agreements and understandings, oral or
otherwise, among the parties hereto with respect to the Warrants, except as

Exercise Price may be made either by (i) certified check payable to the order of
the Company, (ii) surrender of certificates then held representing, or deduction
from the number of shares issuable upon exercise of this Warrant, of that number
of shares which has an aggregate Fair Value determined in accordance with the
Warrant Agreement on the date of exercise equal to the aggregate Exercise Price

Holder stock certificates aggregating the number of shares of Warrant Securities
purchased.

                  (c) In the event the Holder of this Warrant desires that any
or all of the stock certificates to be issued upon the exercise hereof be
registered in a name or names other than that of the Holder of this Warrant, the
Holder must (i) so request in writing at the time of exercise if the transfer is
not a registered transfer, and (ii) provide to the Company evidence reasonably
satisfactory to the Company to the effect that the proposed transfer may be
effected without registration under the Securities Act.

                  (d) Upon the due exercise by the Holder of this Warrant,
whether in whole or in part, the Holder (or any other person to whom a stock
certificate is to be so issued) shall be deemed for all purposes to have become
the Holder of record of the shares of Common Stock for which this Warrant has
been so exercised, effective immediately prior to the close of business on the
date this Warrant, the completed and signed Exercise Form and the requisite
payment were duly delivered to the Company, irrespective of the date of actual

measured by the income of any Person other than the Company) and other charges
imposed by law payable in connection with the transfer or replacement of this
Warrant.

                  (c) The Company shall deliver or cause to be delivered to the

                  (a) The Company at all times shall maintain at its chief
executive offices an open register for all Warrants, in which the Company shall

transferred, the number of shares of Common Stock or other securities
purchasable hereunder and the corresponding purchase prices.

                  (b) This Warrant may be exchanged for two or more warrants
entitling the identical Holder hereof to purchase the same aggregate Exercise
Quantity at the same Exercise Price per share and otherwise having the same
terms and provisions as this Warrant. The identical Holder may request such an
exchange by surrender of this Warrant to the Company, together with a written
exchange request specifying the desired number of warrants and allocation of the
Exercise Quantity purchasable under the existing Warrant.

transfer is not a registered transfer, evidence reasonably satisfactory to the
Company that such transfer is in compliance with federal and state securities
laws. Within five business days

after the Company's receipt of this Warrant and the Assignment Form so completed
and executed, the Company will issue and deliver to the transferee a new Warrant
representing the portion of the Exercise Quantity transferred at the same
Exercise Price per share and otherwise having the same terms and provisions as
this Warrant, which the Company will register in the new Holder's name.

                  (d) Upon receipt by the Company of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant, and (a) in the case of loss, theft or destruction,
upon receipt by the Company of indemnity reasonably satisfactory to it, or (b)
in the case of mutilation, upon surrender and cancellation thereof, the Company,
at its expense, will execute, register and deliver, in lieu thereof, a new
certificate or instrument for (or covering the purchase of) this Warrant.

                  (e) The Company will not close its books against the transfer
of this Warrant or any of the Warrant Securities in any manner which interferes
with the timely exercise of this Warrant. The Company will from time to time
take all such action as may be necessary to assure that the par value per share
of the unissued Common Stock acquirable upon exercise of this Warrant is at all
times equal or less than the Exercise Price then in effect.

         5. Rights and Obligations of the Company and the Holder. The Company
and the Holder of this Warrant are entitled to the rights and bound by the
obligations set forth in the Warrant Agreement, all of which rights and
obligations are hereby incorporated by reference herein. This Warrant shall not
