                              EMPLOYMENT AGREEMENT
                                       and
                             COVENANT NOT TO COMPETE

         EMPLOYMENT AGREEMENT and COVENANT NOT TO COMPETE (the "Employment
Agreement"), by and between WORLDQUEST NETWORKS, INC. ("WorldQuest") and Victor
E. Grijalva ("Executive"), effective as of May 14, 2003.

                                   WITNESSETH:

         WHEREAS, WorldQuest desires to continue to utilize the services of the
Executive as its Vice President, Chief Financial Officer, Treasurer and
Secretary and the Executive is willing to render such services; and

         WHEREAS, WorldQuest and the Executive desire to evidence in this
Employment Agreement the terms under which the Executive will perform such
services;

         NOW THEREFORE, in consideration of the premises and other good and
valuable consideration, receipt of which is hereby acknowledged, the Executive
and WorldQuest agree as follows:

         1. Title and Duties

                  (a) The Executive's title will be Vice President, Chief
         Financial Officer, Treasurer and Secretary of WorldQuest. The
         Executive's duties and responsibilities will be as described in
         WorldQuest's Bylaws (as in effect as of the date of this Employment
         Agreement) and the Executive shall at all times report directly to the
         President and Chief Executive Officer and the Board of Directors of
         WorldQuest, or as otherwise agreed by the Executive. The Executive will
         exercise due diligence and reasonable care in the performance of the
         Executive's duties under this Employment Agreement.

         2. Term

                  (a) Unless earlier terminated as provided for herein, the term
         of this Employment Agreement will be for three years, beginning on
         April 14, 2003, and ending on April 13, 2006 (the "Term").

                  (b) If the Executive's employment with WorldQuest is
         terminated by the Executive due to the Executive's voluntary
         resignation (other than voluntary resignation following "Constructive
         Termination", as defined below) or by WorldQuest for "Cause" (as
         defined below), this Employment Agreement shall terminate immediately
         (except for the provisions of Paragraphs 4, 5, 6 and 7). For purposes
         of this Employment Agreement, the Executive may be terminated for
         "Cause" by majority vote of (excluding the Executive) the Board of
         Directors of WorldQuest as a result of (i) refusal to implement or
         adhere to policies or directives of the Board of Directors of
         WorldQuest; or (ii) gross negligence that is materially injurious to
         the operations or financial condition of WorldQuest; and such conduct
         or condition causing termination for Cause is not cured within thirty
         days after written notice is delivered to the Executive from
         WorldQuest. For these purposes, no refusal to act or failure to adhere
         shall be considered as grounds for Cause unless it is done, or omitted
         to be done, in bad faith without reasonable belief that the action or
         omission was in the best interest of WorldQuest. In the event
         corrective action is not satisfactorily taken by the Executive, a final
         written notice of termination shall be provided to the Executive by
         WorldQuest.

                  (c) If the Executive's employment is terminated during the
         Term of this Employment Agreement due to resignation following
         "Constructive Termination" (as defined below) or for any other reason
         other than the Executive's voluntary resignation or discharge for
         Cause, this Employment Agreement shall terminate immediately (except
         for the confidentiality provisions of Paragraph 4(a) and the provisions
         of Paragraphs 5, 6 and 7) and the Executive shall receive:

                           (i) The Executive's Base Salary as described in
                  Paragraph 3(a) through the date of termination;

<PAGE>

                           (ii) the Executive's regular Base Salary will be
                  continued for a period of six months;

                           (iii) to the extent determined by the stock plan
                  committee, in its sole discretion, full vesting in all stock
                  options previously granted to the Executive (irrespective of
                  the date of the grant of such stock options and irrespective
                  of the vesting schedule otherwise applicable to such stock
                  options; to the extent determined by the stock plan committee,
                  in its sole discretion, the Executive shall be permitted to
                  retain such options for future exercise or sell such stock
                  received on exercise as though the Executive had remained in
                  the employment of WorldQuest until the end of the regular
                  Term, and WorldQuest shall take such actions as are permitted
                  by applicable law to cause such vesting and option retention;
                  and

                           (iv) additionally, the provisions of Paragraphs 7(g)
                  and 7(h) shall remain in effect as though this Employment
                  Agreement expired at the end of its regular Term described in
                  Paragraph 2(a), irrespective of its earlier termination.

                  For purposes of this Employment Agreement a "Constructive
         Termination" shall be deemed to have occurred in the event that (i) the
         Executive's Base Salary as defined in Paragraph 3(a), bonus
         compensation under Paragraph 3(b), other compensation as described in
         Paragraphs 3(c) and 3(d) is reduced; (ii) a significant diminution in
         the Executive's responsibilities, authority or scope of duties is
         effected by the Board of Directors and such diminution is made without
         the Executive's written consent (without regard to whether or not any
         change is made to the Executive's title); (iii) WorldQuest materially
         breaches this Employment Agreement or (iv) a Change in Control of
         WorldQuest occurs. For purposes of this Employment Agreement, a "Change
         in Control of WorldQuest" means the occurrence of any of the following
         events after the date hereof: (a) any "person" or "group" (as such
         terms are used in Sections 13(d) and 14(d) of the Securities Exchange
         Act of 1934, as amended (the "Exchange Act")) is or becomes the
         "beneficial owner" (as defined in Rule l3d-3 under the Exchange Act),
         directly or indirectly, of more than 20% of the total voting stock of
         WorldQuest; (b) WorldQuest is merged with or into or consolidated with
         another person and, immediately after giving effect to the merger or
         consolidation, (A) less than 80% of the total voting power of the
         outstanding voting stock of the surviving or resulting person is then
         "beneficially owned" (within the meaning of Rule l3d-3 under the
         Exchange Act) in the aggregate by (x) the stockholders of WorldQuest
         immediately prior to such merger or consolidation, or (y) if a record
         date has been set to determine the stockholders of WorldQuest entitled
         to vote with respect to such merger or consolidation, the stockholders
         of WorldQuest as of such record date and (B) any "person" or "group"
         (as defined in Section 13(d)(3) or 14(d)(2) of the Exchange Act) has
         become the direct or indirect "beneficial owner" (as defined in Rule
         l3d-3 under the Exchange Act) of more than 20% of the voting power of
         the voting stock of the surviving or resulting person; (c) WorldQuest,
         either individually or in conjunction with one or more of its
         subsidiaries, sells, assigns, conveys, transfers, leases or otherwise
         disposes of, or the subsidiaries sell, assign, convey, transfer, lease
         or otherwise dispose of, all or substantially all of the properties and
         assets of WorldQuest and the subsidiaries, taken as a whole (either in
         one transaction or a series of related transactions), to any person
         (other than WorldQuest or a wholly owned subsidiary); or (d) the
         liquidation or dissolution of WorldQuest. Any resignation by the
         Executive as a result of assertion of a Constructive Termination shall
         be communicated by delivery to the President and Chief Executive
         Officer of WorldQuest of thirty days' advance written notice of such
         Constructive Termination and the grounds therefor, during which period
         WorldQuest shall be entitled to cure or remedy the matters set forth in
         such notice to the Executive's reasonable satisfaction. Unless the
         Executive shall withdraw such notice prior to the expiration of such
         thirty day period, such resignation shall take effect upon the
         expiration of thirty days from the date of the delivery of such notice.
         Any other resignation by the Executive shall be communicated by thirty
         days' advance written notice.

                  (d) If the Executive shall die, or become disabled and cannot
         perform the Executive's duties, this Employment Agreement shall
         terminate immediately. For purposes of this Employment Agreement, the
         Executive shall be disabled as of the first date on which the Executive
         shall become eligible to receive disability benefits under WorldQuest's
         long-term disability plan (or Social Security disability benefits at a
         time when WorldQuest does not maintain a long-term disability plan or
         such plan is not available to the Executive). WorldQuest will maintain
         for a period of twenty-four months from the date of the Executive's
         death or disability, all Directors and Officers Liability Insurance
         that WorldQuest was maintaining for the Executive and/or the
         Executive's estate as of the date of the Executive's death or
         disability.

         3. Compensation

                  (a) Each year during the Term hereof, the Executive will be
         paid a base salary of $150,000 per annum ("Base Salary"), payable in
         accordance with WorldQuest's payroll guidelines, subject to applicable
         tax and benefit plan withholding. Increases may be made to the
         Executive's Base Salary at the discretion of the President and Chief
         Executive Officer, based upon the Executive's individual performance.

                  (b) The Executive shall be a participant in any incentive
         compensation plan sponsored by WorldQuest, at the highest level of
         executive participation.

                  (c) The Executive shall be designated as a participant in one
         or more option or stock-based compensation plans established by
         WorldQuest, and shall be entitled to purchase shares of common stock of
         WorldQuest provided thereunder.

                  (d) The Executive shall be entitled to participate in all of
         WorldQuest's benefit programs for senior management executives. The
         Executive shall participate in, and be eligible to receive benefits
         under, any "employee welfare benefit plans" and "employee pension
         benefit plans" (as such terms are defined in the Employee Retirement
         Income Security Act of 1974, as amended) and business travel insurance
         plans and programs as shall apply to general and/or executive employees
         of WorldQuest.

                  (e) The Executive shall be entitled to participate in such
         other compensation arrangements and receive such other perquisites as
         the Board of Directors of WorldQuest in its sole discretion determines,
         provided that WorldQuest shall pay or reimburse the Executive for all
         reasonable business, travel or entertainment expenses incurred in
         connection with the performance of services under this Employment
         Agreement. WorldQuest shall furnish the Executive with an office
         commensurate with the Executive's title and adequate for the
         performance of the Executive's duties, and with secretarial assistance
         and similar services.

         4. Confidentiality and Non-Competition

                  (a) The Executive recognizes and acknowledges that the
         Executive will have access to certain information concerning WorldQuest
         that is confidential and proprietary and constitutes valuable and
         unique property of WorldQuest. The Executive agrees that the Executive
         will not at any time, either during or after the Executive's
         employment, disclose to others, use, copy or permit to be copied,
         except pursuant to the Executive's duties on behalf of WorldQuest or
         its successors, assigns or nominees, any secret or confidential
         information of WorldQuest (whether or not developed by the Executive)
         without the prior written consent of the Board of Directors of
         WorldQuest.

                  (b) The Executive and WorldQuest agree that the Executive, by
         virtue of his position with WorldQuest, is in possession of highly
         sensitive information regarding WorldQuest's investors, contracts,
         plans and operations, and those of its corporate affiliates, that the
         Executive is WorldQuest's representative to current and potential
         clients, that other entities each compete vigorously with WorldQuest
         throughout various portions of WorldQuest's area of operations, and the
         Executive's use of such knowledge for the benefit of a competitor of
         WorldQuest would provide a competitive advantage to a competitor that
         would be highly detrimental to WorldQuest. The Executive's skills,
         knowledge and services are unique, and the success or failure of
         WorldQuest is dependent upon the Executive's services. The Executive
         agrees that WorldQuest has a legitimate business interest in protecting
         this information and preventing competitors from utilizing such
         information. Therefore, the Executive agrees that, for a period of
         twelve months following the termination of this Employment Agreement by
         the Executive other than due to Constructive Termination or discharge
         without Cause, the Executive will not engage in any Prohibited
         Competitive Activities as provided in Paragraph 4(c) below.

                                       3
<PAGE>

                  (c) During the time period specified in Section 4(b), the
         Executive shall not:

                           (1) Directly or indirectly own, operate, manage,
                  consult with, control, participate in the management or
                  control of, be employed by, maintain or continue any interest
                  whatsoever in any international interest telephony and/or
                  money transfer business or enterprise the principal markets of
                  which are the United States and/or India; or

                           (2) Directly or indirectly solicit business from any
                  individual or entity doing regular and substantial business
                  with WorldQuest in the United States and/or India at any time
                  during the Term of this Employment Agreement.

                  Such activities are defined as "Prohibited Competitive
         Activities".

                  (d) WorldQuest and the Executive agree that money damages may
         not be adequate to compensate WorldQuest for the Executive's breach of
         any provision of this Paragraph 4 and that WorldQuest therefor will be
         entitled to a decree for specific performance of other appropriate
         remedy, including injunctive relief, to enforce the Executive's
         performance of any such provision. The Executive expresses, agrees and
         acknowledges that this Covenant Not to Compete is necessary for the
         protection of WorldQuest because of the nature and scope of its
         business and the Executive's position with, and services for,
         WorldQuest. The Executive acknowledges that any breach of this Covenant
         Not to Compete would result in irreparable damage to WorldQuest.

                  (e) The Executive expressly agrees and acknowledges as
         follows:

                           (1) This Covenant Not to Compete is reasonable as to
                  time and geographical area and does not place any unreasonable
                  burden upon the Executive;

                           (2) The general public will not be harmed as a result
                  of enforcement of this Covenant Not to Compete;

                           (3) The Executive has requested or has had the
                  opportunity to request that his personal legal counsel review
                  this Covenant Not to Compete; and

                           (4) The Executive understands and hereby agrees to
                  each and every term and condition of this Covenant Not to
                  Compete.

         5. Indemnification

                  If, at any time during or after the Term of this Employment
         Agreement, the Executive is made a party to, or is threatened to be
         made a party in, any civil, criminal or administrative action, suit or
         proceeding by reason of the fact that the Executive is or was a
         director, officer, employee, or agent of WorldQuest, or of any other
         corporation or any partnership, joint venture, trust or other
         enterprise for which the Executive served as such at the request of
         WorldQuest, then the Executive shall be indemnified by WorldQuest
         against expenses actually and reasonably incurred by the Executive or
         imposed on the Executive in connection with, or resulting from, the
         defense of such action, suit or proceeding, or in connection with, or
         resulting from, any appeal therein if the Executive acted in good faith
         and in a manner the Executive reasonably believed to be in or not
         opposed to the best interest of WorldQuest, and, with respect to any
         criminal action or proceeding, had no reasonable cause to believe the
         Executive's conduct was unlawful, except with respect to matters as to
         which it is adjudged that the Executive is liable to WorldQuest or to
         such other corporation, partnership, joint venture, trust or other
         enterprise for gross negligence or willful misconduct in the
         performance of the Executive's duties. As used herein, the term
         "expenses" shall include all obligations actually and reasonably
         incurred by the Executive for the payment of money, including, without
         limitation, attorney's fees, judgments, awards, fines, penalties and
         amounts paid in satisfaction of a judgment or in settlement of any such
         action, suit or proceeding, except amounts paid to WorldQuest or such
         other corporation, partnership, joint venture, trust or other
         enterprise by the Executive.

                                       4

         6. Arbitration

                  Except as provided in Paragraph 4, any controversy or claim
         arising out of or relating to this Employment Agreement, or any breach
         thereof, except as provided in Paragraph 4 shall be adjudged only by
         arbitration in accordance with the rules of the American Arbitration
         Association, and judgment upon such award rendered by the arbitrator
         may be entered in any court having jurisdiction thereof. The
         arbitration shall be held in the City of Dallas, Texas, or such other
         place as may be agreed upon at the time by the parties to the
         arbitration. The arbitrator(s) shall, in their award, allocate between
         the parties the costs of arbitration, which shall include reasonable
         attorneys' fees of the parties, as well as the arbitrators' fees and
         expenses, in such proportions as the arbitrator(s) deem just.

         7. Other Provisions

                  (a) This Employment Agreement will be governed by, and
         construed and enforced in accordance with, the laws of the State of
         Texas, excluding any conflicts of law, rule or principle that might
         otherwise refer to the substantive law of another jurisdiction.

                  (b) Except as otherwise indicated, this Employment Agreement
         is not assignable without the written authorization of both parties;
         provided that WorldQuest may assign this Employment Agreement to any
         entity to which WorldQuest transfers substantially all of its assets or
         to any entity which is a successor to WorldQuest by reorganization,
         incorporation, merger or similar business combination. In the event of
         any such transfer or assignment by WorldQuest, the rights and
         privileges of the Board hereunder shall be vested in the Board of
         Directors or other governing body of the transferee or successor
         entity. However, notwithstanding anything to the contrary contained
         herein, this Employment Agreement will be binding upon any successor
         (whether direct or indirect, by purchase, merger, consolidation or
         otherwise) to all or substantially all of the business and/or assets of
         WorldQuest, and WorldQuest will require any such successor by
         agreement, in form and substance satisfactory to the Executive, to
         expressly assume and agree to perform this Employment Agreement in the
         same manner and to the same extent that WorldQuest would be required to
         perform if no such succession had taken place. In addition to the
         Executive's rights above, if a Change in Control of WorldQuest occurs
         as described in Paragraph 2(c) above, the failure of WorldQuest to
         obtain such agreement prior to the effectiveness of any such succession
         shall be a breach of this Employment Agreement and shall entitle the
         Executive to compensation from WorldQuest in the same amount and on the
         same terms as the Executive would be entitled to hereunder if the
         Executive resigned from the Executive's employment due to a
         Constructive Termination, as described in Paragraph 2(c) above, except
         that for purposes of implementing the foregoing, the date on which any
         such succession becomes effective shall be deemed the date of
         termination. As used in this Employment Agreement, "WorldQuest" shall
         mean WorldQuest as hereinbefore defined and any successor to its
         business and/or assets as aforesaid which executes and delivers the
         agreement provided for in this Paragraph 7(b) or which otherwise
         becomes bound by all the terms and provisions of this Employment
         Agreement by operation of law. This Employment Agreement and all rights
         of the parties hereto shall inure to the benefit of and be enforceable
         by the parties hereto, their assigns, personal or legal
         representatives, executors, administrators, successors, heirs,
         distributees, devises and legatees.

                  (c) Except as otherwise provided herein, the provisions of
         Paragraphs 4, 5 and 6 of this Employment Agreement shall survive the

         of any breach by the other party hereto of any condition or provision
         of this Employment Agreement to be performed by such other party shall

         provision or a waiver of a similar or dissimilar provision or condition
         at the same or at any prior or subsequent time.

                  (e) Any notice or other communication required or permitted

                  (f) If any one or more of the provisions or parts of a
         provision contained in this Employment Agreement including, without
         limitation, the restrictions contained in Paragraph 4, shall for any
         reason be held to be invalid, illegal or unenforceable in any respect,
         such invalidity or unenforceability shall not affect any other
         provision or part of a provision of this Employment Agreement, but this
         Employment Agreement shall be reformed and construed as if such invalid
         or illegal or unenforceable provision or part of a provision had never
         been contained herein and such provisions or part thereof shall be
         reformed so that it would be valid, legal and enforceable to the
         maximum extent permitted by law.

                  (g) The Executive shall not be required to mitigate damages
         (or the amount of any compensation provided under this Employment
         Agreement to be paid) following the Executive's termination of
         employment, by seeking employment or otherwise.

                  (h) WorldQuest shall maintain during the Term of this
         Employment Agreement and for a period of twenty-four months thereafter
         Directors and Officers Liability Insurance covering the Executive (or
         the Executive's estate, if the Executive is deceased or incompetent),
         which provides coverage at least as favorable to the Executive (or the
         Executive's estate, if the Executive is deceased or incompetent), as
         coverage under WorldQuest's policy in effect on the date of execution
         of this Employment Agreement, and which coverage shall be increased
         from time to time in such amounts as the Board may determine to be
         appropriate in light of WorldQuest's operations.

                  (i) WorldQuest will not amend the provisions of its governing
         documents which pertain to the Executive's indemnification in the
         Executive's capacity as an officer and/or member of the Board of
         WorldQuest except to substitute therefor provisions which are more
         favorable to the Executive, except as otherwise required by law or the
         rules of any securities exchange or similar entity, or by applicable
         law.

                                WARRANT AGREEMENT

THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE HEREOF
HAVE NOT BEEN REGISTERED UNDER EITHER THE SECURITIES ACT OF 1933, AS AMENDED
("ACT") OR APPLICABLE STATE SECURITIES LAWS ("STATE ACTS") AND SHALL NOT BE
SOLD, PLEDGED, HYPOTHECATED, DONATED, OR OTHERWISE TRANSFERRED (WHETHER OR NOT
FOR CONSIDERATION) BY THE HOLDER EXCEPT UPON THE ISSUANCE TO THE COMPANY OF AN
OPINION OF COUNSEL OR SUBMISSION TO THE COMPANY OF SUCH EVIDENCE AS MAY BE
SATISFACTORY TO COUNSEL TO THE COMPANY, IN EACH SUCH CASE, TO THE EFFECT THAT
ANY SUCH TRANSFER SHALL NOT BE IN VIOLATION OF THE ACT AND THE STATE ACTS.

              WARRANT TO PURCHASE 1,881,250 SHARES OF COMMON STOCK

                        TERAFORCE TECHNOLOGY CORPORATION
                            (a Delaware corporation)
                              1240 E. Campbell Road
                             Richardson, Texas 75081

                     Not Transferable or Exercisable Except
                        upon Conditions Herein Specified

         TERAFORCE TECHNOLOGY CORPORATION, a Delaware corporation ("Company"),
hereby certifies that ODYSSEY CAPITAL, LLC, its registered successors and
permitted assigns registered on the books of the Company maintained for such
purposes, as the registered holder hereof ("Holder"), for value received, is
entitled to purchase from the Company the number of fully paid and
non-assessable shares of Common Stock of the Company, $.01 par value ("Shares"
or "Common Stock"), stated above at the purchase price per Share set forth in
Section 1(b) below (the number of Shares and Exercise Price being subject to
adjustment as hereinafter provided) upon the terms and conditions herein
provided.

                                    RECITALS

         WHEREAS, Odyssey Capital, LLC was engaged by the Company to serve as
its non-exclusive financial advisor and pursuant to such engagement, the Company
is hereby issuing to Holder, a warrant to purchase shares of Common Stock (this
"Warrant"), subject to the following terms and conditions:

         1.       Exercise of Warrants.

         (a) Subject to subsection (b) of this Section 1, upon presentation and
surrender of this Warrant Agreement, with the attached Purchase Form duly
executed, at the principal office of the Company, or at such other place as the
Company may designate by notice to the Holder hereof, together with a certified
or bank cashier's check payable to the order of the Company in the amount of the
Exercise Price times the number of Shares being purchased (or in the case of
exercise pursuant to Section 1(c)(i) or (ii), as set forth in such sections),
the Company shall deliver to the Holder hereof, as promptly as practicable,
certificates representing the Shares being purchased. This Warrant may be
exercised in whole or in part; and, in case of exercise hereof in part only, the
Company, upon surrender hereof, will deliver to the Holder a new Warrant
Agreement or Warrant Agreements of like tenor entitling the Holder to purchase
the number of Shares as to which this Warrant has not been exercised.

WARRANT AGREEMENT                                                 AUGUST 4, 2003
                                       1
<PAGE>
         (b) This Warrant may be exercised at a price of $0.16 per share (the
"Exercise Price"); provided however, that the Exercise Price shall be subject to
adjustment pursuant to Section 6(b). The Warrant shall expire upon the close of
business July 31, 2007.

         (c) The Exercise Price shall be payable at the time of exercise. The
Exercise Price may be paid in cash (by cashiers' check) or by: (i) surrender of
shares of Common Stock of the Company already owned by the Holder, having a
Market Price (as defined below) equal to the Exercise Price per share; or (ii)
upon surrender of the Warrant at the principal office of the Company together
with notice of election, in which event the Company shall issue Holder a number
of Shares computed using the following formula:

                  X = Y (A-B)/A

where:            X = the number of Shares to be issued to Holder (not to exceed
                  the number of Shares set forth on the cover page of this
                  Warrant Agreement, as adjusted pursuant to the provisions of
                  Section 6 of this Warrant Agreement).

                  Y = the number of Shares for which the Warrant is being
                  exercised.

                  A = the Market Price of one Share (for purposes of this
                  Section 1(c)), the "Market Price" shall be defined as the
                  average closing price on the exchange on which the Common
                  Stock trades for the five trading days prior to the date of
                  exercise of this Warrant Agreement; provided if the Common
                  Stock does not trade on any exchange, the Market Price shall
                  equal the average closing bid price in the over-the-counter
                  market for the five trading days prior to the date of exercise
                  of this Warrant Agreement, as reported by the National
                  Association of Securities Dealers Automated Quotation System;
                  and, provided further, that if the common stock is not quoted
                  or listed by any organization, the fair value of the common
                  stock, as determined by the Board of Directors of the Company,
                  whose determination shall be conclusive, shall be used).

                  B = the Exercise Price.

         2.       Exchange and Transfer of Warrant.

         At any time prior to the exercise hereof, upon presentation and
surrender to the Company, this Warrant (a) may be exchanged, alone or with other
Warrants of like tenor registered in the name of the Holder, for another Warrant
or other Warrants of like tenor in the name of such Holder exercisable for the
same aggregate number of Shares as the Warrant or Warrants surrendered, but (b)
may not be sold, transferred, hypothecated, or assigned, in whole or in part,
without the prior written consent of the Company.

         3.       Rights and Obligations of Warrant Holder.

         (a) The Holder of this Warrant Agreement shall not, by virtue hereof,
be entitled to any rights of a stockholder in the Company, either at law or in
equity; provided, however, that in the event that any certificate representing
the Shares is issued to the Holder hereof upon exercise of this Warrant, such
Holder shall, for all purposes, be deemed to have become the holder of record of
such Shares on the date on which this Warrant Agreement, together with a duly
executed Purchase Form, was surrendered and payment of the Exercise Price was
made, irrespective of the date of delivery of such Share certificate. The rights
of the Holder of this Warrant are limited to those expressed herein and the
Holder of this Warrant, by his acceptance hereof, consents to and agrees to be
bound by and to comply with all the provisions of this Warrant Agreement,
including, without limitation, all the obligations imposed upon the Holder
hereof by Sections 2 and 5 hereof. In addition, the Holder of this Warrant
Agreement, by accepting the same, agrees that the Company may deem and treat the
person in whose name this Warrant Agreement is registered on the books of the
Company maintained for such

WARRANT AGREEMENT                                                 AUGUST 4, 2003
                                       2
<PAGE>

purposes as the absolute, true and lawful owner for all purposes whatsoever,
notwithstanding any notation of ownership or other writing thereon, and the
Company shall not be affected by any notice to the contrary.

         (b) No Holder of this Warrant Agreement shall be entitled to vote or
receive dividends or to be deemed the holder of Shares for any purpose, nor
shall anything contained in this Warrant Agreement be construed to confer upon
any Holder of this Warrant Agreement any of the rights of a stockholder of the
Company or any right to vote, give or withhold consent to any action by the
Company, whether upon any recapitalization, issue of stock, reclassification of
stock, consolidation, merger, conveyance or otherwise, receive notice of
meetings or other action affecting stockholders (except for notices provided for
herein), receive dividends, subscription rights, or otherwise, until this
Warrant shall have been exercised and the Shares purchasable upon the exercise
thereof shall have become deliverable as provided herein; provided, however,
that any such exercise on any date when the stock transfer books of the Company
shall be closed shall constitute the person in whose name the certificate for
those Shares are to be issued as the record holder thereof for all purposes at
the opening of business on the next succeeding day on which such stock transfer
books are open, and the Warrant surrendered shall not be deemed to have been
exercised, in whole or in part as the case may be, until the next succeeding day
on which stock transfer books are open for the purpose of determining
entitlement to dividends on the Company's common stock.

         4.       Shares Underlying Warrant.

         The Company covenants and agrees that all Shares delivered upon
exercise of this Warrant shall, upon delivery and payment therefor, be duly and
validly authorized and issued, fully paid and non-assessable, and free from all
stamp taxes, liens and charges with respect to the purchase thereof.

         5.       Representations and Warranties of Holder; Disposition of
                  Warrant or Shares.

         (a) The Holder acknowledges that it has had access to all material
information concerning the Company which it has requested. The Holder also
acknowledges that it has had the opportunity to, and has to its satisfaction,
questioned the officers of the Company with respect to this Warrant. The Holder
is purchasing the Warrant and any Common Stock issued upon exercise thereof for
investment for its own account only and not with a view to, or for resale in
connection with, any "distribution" thereof in violation of the Act or State
Acts. The Holder further represents that it understands that the Warrant and
Common Stock to be issued upon exercise thereof have not been registered under
the Act or State Acts by reason of specific exemptions therefrom, which
exemptions depend upon, among other things, the bona fide nature of the Holder's
investment intent as expressed herein. The Holder is an "accredited investor" as
defined in Regulation D promulgated under the Act.

         (b) The Holder of this Warrant Agreement and any transferee hereof or
of the Shares issuable upon the exercise of the Warrant Agreement, by their
acceptance hereof, hereby understand and agree that the Warrant, and the Shares
issuable upon the exercise hereof, have not been registered under either the Act
or State Acts and shall not be sold, pledged, hypothecated, or otherwise
transferred (whether or not for consideration) except upon the issuance to the
Company of an opinion of counsel favorable to the Company or its counsel or
submission to the Company of such evidence as may be satisfactory to the Company
or its counsel, in each such case, to the effect that any such transfer shall
not be in violation of the Act or the State Acts. It shall be a condition to the
transfer of this Warrant that any transferee of this Warrant deliver to the
Company his written agreement to accept and be bound by all of the terms and
conditions of this Warrant Agreement.

         (c) The stock certificates of the Company that will evidence the shares
of Common Stock with respect to which this Warrant may be exercisable will be
imprinted with a conspicuous legend in substantially the following form:

<PAGE>

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER EITHER THE SECURITIES ACT OF 1933 ("ACT") OR
                  THE SECURITIES LAWS OF ANY STATE ("STATE ACTS"). SUCH
                  SECURITIES SHALL NOT BE SOLD, PLEDGED, HYPOTHECATED, OR
                  OTHERWISE TRANSFERRED (WHETHER OR NOT FOR CONSIDERATION) AT
                  ANY TIME WHATSOEVER EXCEPT UPON REGISTRATION OR UPON DELIVERY
                  TO THE COMPANY OF AN OPINION OF ITS COUNSEL SATISFACTORY TO
                  THE COMPANY OR ITS COUNSEL THAT REGISTRATION IS NOT REQUIRED
                  FOR SUCH TRANSFER OR THE SUBMISSION OF SUCH OTHER EVIDENCE AS
                  MAY BE SATISFACTORY TO THE COMPANY OR ITS COUNSEL TO THE
                  EFFECT THAT ANY SUCH TRANSFER SHALL NOT BE IN VIOLATION OF THE
                  ACT, STATE ACTS OR ANY RULE OR REGULATION PROMULGATED
                  THEREUNDER."

         (d) The Company has granted Holder registration rights to the shares
underlying this Warrant, as set forth in the Registration Rights Agreement
between the Company and the Holder dated July 3, 2003.

         6.       Adjustments.

         The number of Shares purchasable upon the exercise of each Warrant is
subject to adjustment from time to time upon the occurrence of any of the events
enumerated below:

         (a) If at any time after the date of this Warrant and so long as this
Warrant is outstanding, there is (i) a stock split, stock dividend, subdivision,
or similar distribution with respect to the Common Stock, (ii) a combination of
the Common Stock, or (iii) a sale or issuance of Common Stock, or exchangeable
for its Common Stock, or any rights, options or warrants to subscribe for or to
purchase of its Common Stock, then, in such event, the Exercise Price shall be
adjusted in accordance with (b) below.

         (b) Immediately upon the effective date of any event requiring
adjustment pursuant to (a), the Company shall adjust the Exercise Price then in
effect (to the nearest whole cent) as follows:

                  (i) If the Company (A) shall pay a stock dividend or otherwise
         make a distribution or distributions on shares of its Common Stock
         payable in shares of Common Stock, (B) subdivide outstanding shares of
         Common Stock into a larger number of shares, (C) combine outstanding
         shares of Common Stock into a smaller number of shares, or (D) issue by
         reclassification of shares of Common Stock any shares of capital stock
         of the Company, the Exercise Price shall be multiplied by a fraction of
         which the numerator shall be the number of shares of Common Stock
         (excluding treasury shares, if any) outstanding before such event and
         of which the denominator shall be the number of shares of Common Stock
         outstanding after such event. Any adjustment made pursuant to this
         subparagraph (i) shall become effective immediately after the record
         date for the determination of stockholders entitled to receive such
         dividend or distribution and shall become effective immediately after
         the effective date in the case of a subdivision, combination or
         re-classification.

                  (ii) If the Company shall distribute to all holders of Common
         Stock evidences of its indebtedness or assets or rights or warrants to
         subscribe for or purchase any security (excluding those referred to in
         subparagraph (i) above), then in each such case the Exercise Price
         shall be determined by multiplying the Exercise Price in effect
         immediately prior to the record date fixed for determination of
         stockholders entitled to receive such distribution by a fraction of
         which the denominator shall be the Market Price of Common Stock
         determined as of the record date mentioned above, and of which the
         numerator shall be such Market Price of the Common Stock on such record
         date less the then fair market value at such record date of the portion
         of such assets or evidence of indebtedness so distributed applicable to
         one outstanding share of Common Stock as determined by the Company's
         board of directors in good faith; provided, however, that if the Holder
         disputes such amount, the Holder may select a nationally recognized or
         major regional investment banking firm or firm of independent certified

WARRANT AGREEMENT                                                 AUGUST 4, 2003
                                       4
<PAGE>

         public accountants of recognized standing (an "Appraiser") paid for by
         the Holder and the Company equally, in which case the fair market value
         shall be equal to the average of the determinations by the Company's
         board of directors and such Appraiser. In either case the adjustments
         shall be described in a statement provided to the Holder of the portion
         of assets or evidences of indebtedness so distributed or such
         subscription rights applicable to one share of Common Stock. Such
         adjustment shall be made whenever any such distribution is made and
         shall become effective immediately after the record date mentioned
         above.

                  (iii) In case the Company (A) consolidates with or merges into
         any other entity and is not the continuing or surviving entity of such
         consolidation or merger, or (B) permits any other entity to consolidate
         with or merge into the Company and the Company is the continuing or
         surviving Company but, in connection with such consolidation or merger,
         the Common Stock is changed into or exchanged for common stock or other
         securities of any other entity or cash or any other assets, or (C)
         transfers all or substantially all of its properties and assets to any
         other entity, or (D) effects a reorganization or reclassification of
         the equity of the Company in such a way that holders of Common Stock
         shall be entitled to receive stock, securities, cash or assets with
         respect to or in exchange for Common Stock, then, and in each such
         case, proper provision shall be made so that, upon the exercise of the
         Warrant at any time after the consummation of such consolidation,
         merger, transfer, reorganization or reclassification, the Holder shall
         be entitled to receive (at the Exercise Price in effect for Common
         Stock issuable upon such exercise of the Warrant immediately prior to
         such consummation), in lieu of Common Stock issuable upon such exercise
         of the Warrant prior to such consummation, the stock and other
         securities, cash and assets to which the Holder would have been
         entitled upon such consummation if such Holder had so exercised the
         Warrant immediately prior thereto.

                  (iv) In the event that the Company issues or sells any Common
         Stock or securities which are convertible into or exchangeable for its
         Common Stock, or any rights, options or warrants to subscribe for or to
         purchase its Common Stock for "Consideration" (as defined below) at a
         price per share ("Per Share Selling Price") which is less than the
         Exercise Price in effect immediately prior to the time of such issue or
         sale, then the Exercise Price shall be adjusted downward to equal such

                  received, before deducting therefrom any commissions or
                  expenses paid by the Company.

                           (W) In case of the issuance (otherwise than upon

                  the Company) of additional shares of Common Stock for a
                  consideration other than cash or a consideration partly other
                  than cash, the amount of the consideration other than cash
                  received by the Company for such shares shall be deemed to be
                  the fair value of such consideration as determined in good
                  faith by the Company's board of directors.

                           (X) In the case of the issuance by the Company in any
                  manner of any rights to subscribe for or to purchase shares of
                  Common Stock, or any options for the purchase of shares of
                  Common Stock or stock convertible into Common Stock, all
                  shares of Common Stock or stock convertible into Common Stock
                  to which the holders of such rights or options shall be
                  entitled to subscribe for or purchase pursuant to such rights
                  or options shall be deemed to be outstanding as of the date of
                  the offering of such rights or the granting of such options,
                  as the case may be, and the minimum aggregate consideration
                  named in such rights or options for the shares of Common Stock
                  or stock convertible into Common Stock covered thereby, plus
                  the consideration, if any, received by the Company for such
                  rights or options, shall be deemed to be the "Consideration"
                  received by the Company (as of the date of the offering of
                  such rights or the granting of such options, as the case may
                  be) for the issuance of such shares.

                           (Y) In case of the issuance or issuances by the
                  Company in any manner of any obligations or of any shares of
                  stock of the Company that shall be convertible into or
                  exchangeable for Common Stock, all shares of Common Stock
                  issuable upon the conversion or exchange of such obligations
                  or shares shall be deemed to be issued as of the date such
                  obligations or shares are issued, and the amount of the
                  "Consideration" received by the Company for such additional
                  shares of Common Stock shall be deemed to be the total of (x)
                  the amount of consideration received by the Company upon the
                  issuance of such obligations or shares, as the case may be,
                  plus (y) the minimum aggregate consideration, if any, other
                  than such obligations or shares, receivable by the Company
                  upon such conversion or exchange, except in adjustment of
                  dividends.

                           (Z) The amount of the "Consideration" received by the
                  Company upon the issuance of any rights or options referred to
                  in subparagraph (X) above or upon the issuance of any
                  obligations or shares which are convertible or exchangeable as
                  described in subparagraph (Y) above, and the amount of the
                  consideration, if any, other than such obligations or shares
                  so convertible or exchangeable, receivable by the Company upon
                  the exercise, conversion or exchange thereof shall be
                  determined in the same manner provided in subparagraphs (V)
                  and (W) above with respect to the consideration received by
                  the Company in case of the issuance of additional shares of
                  Common Stock; provided, however, that if such obligations or
                  shares of stock so convertible or exchangeable are issued in
                  payment or satisfaction of any dividend upon any stock of the
                  Company other than Common Stock, the amount of the
                  "Consideration" received by the Company upon the original
                  issuance of such obligations or shares of stock so convertible
                  or exchangeable shall be deemed to be the value of such
                  obligations or shares of stock, as of the date of the adoption
                  of the resolution declaring such dividend, as determined by
                  the board of directors as of that date. Upon the expiration of
                  any rights or options referred to in subparagraph (X), or the
                  termination of any right of conversion or exchange referred to
                  in subparagraph (Y), or any change in the number of shares of
                  Common Stock deliverable upon exercise of such options or
                  rights or upon conversion of or exchange of such convertible
                  or exchangeable securities, the Exercise Price then in effect
                  shall forthwith be readjusted to such Exercise Price as would
                  have obtained had the adjustments made upon the issuance of
                  such options, rights or convertible or exchangeable securities
                  been made upon the basis of the delivery of only the number of
                  shares of Common Stock actually delivered or to be delivered
                  upon the exercise of such rights or options or upon the
                  conversion or exchange of such securities.

         (c) Upon each adjustment of the Exercise Price pursuant to (b) above,
the Warrant outstanding prior to such adjustment in the Exercise Price shall
thereafter evidence the right to purchase, at the adjusted Exercise Price, that
number of shares of Common Stock (calculated to the nearest hundredth) obtained
by (i) multiplying the number of shares of Common Stock issuable upon exercise
of the Warrant prior to adjustment

of the number of shares of Common Stock by the Exercise Price in effect prior to
adjustment of the Exercise Price and (ii) dividing the product so obtained by
the Exercise Price in effect after such adjustment of the exercise price.

         (d) In case the Company (i) consolidates with or merges into any other
entity and is not the continuing or surviving entity of such consolidation or
merger, or (ii) permits any other entity to consolidate with or merge into the
Company and the Company is the continuing or surviving Company but, in
connection with such consolidation or merger, the Common Stock is changed into
or exchanged for common stock or other securities of any other entity or cash or
any other assets, or (iii) transfers all or substantially all of its properties
and assets to any other entity, or (iv) effects a reorganization or
reclassification of the equity of the Company in such a way that holders of
Common Stock shall be entitled to receive stock, securities, cash or assets with
respect to or in exchange for Common Stock, then, and in each such case, proper
provision shall be made so that, upon the exercise of this Warrant at any time
after the consummation of such consolidation, merger, transfer, reorganization
or reclassification, the Holder shall be entitled to receive (at the aggregate
Exercise Price in effect for Common Stock issuable upon such exercise of this
Warrant immediately prior to such consummation), in lieu of Common Stock
issuable upon such exercise of this Warrant prior to such consummation, the
stock and other securities, cash and assets to which such Holder would have been
entitled upon such consummation if such Holder had so exercised this Warrant
immediately prior thereto.

         7.       Loss or Destruction.

         Upon receipt of evidence satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant Agreement and, in the case of
any such loss, theft or destruction, upon delivery of an indemnity agreement or
bond satisfactory in form, substance and amount to the Company or, in the case
of any such mutilation, upon surrender and cancellation of this Warrant
Agreement, the Company will execute and deliver, in lieu thereof, a new Warrant
Agreement of like tenor.

         8.       Survival.

         The various representations, warranties, rights and obligations of the
Holder hereof as set forth herein shall survive the exercise of the Warrants
represented hereby and the surrender of this Warrant Agreement.

         9.       Notices.

         Whenever any notice, payment of any purchase price, or other
communication is required to be given or delivered under the terms of this
Warrant, it shall be in writing and delivered by hand delivery or United States
registered or certified mail, return receipt requested, postage prepaid (or
similar delivery if outside of the United States), and will be deemed to have
been given or delivered on the date such notice, purchase price or other
communication is so delivered or posted, as the case may be; and, if to the
