AGREEMENT

      This Agreement ("Agreement") is made as of the 15th day of December, 2005,
by and between Global Resource Corporation, a Nevada corporation (the "Debtor")
and Transnix Global Corporation, a Nevada corporation (the "Secured Party").

                                    RECITALS

      A. Secured Party is the holder of certain 8% convertible debentures (the
"Debentures") issued by the Debtor in the principal amount of $137,900.00, with
accrued interest to date of approximately $11,732.00

      B. The obligations under the Debentures are secured by a 50% membership
interest (the "Membership Interest") in Well Renewal, LLC, a Nevada limited
liability company ("Well Renewal"), which were pledged to the Secured Party (the
"Collateral") under the terms of that certain Pledge Agreement dated as of
November 18, 2005 by and among the Debtor and the Secured Party (the "Pledge
Agreement").

      C. Debtor has failed to make any of the payments under the Debentures
resulting in an Event of Default under the Debentures and the Pledge Agreement,
thereby giving Secured Party rise to all rights and remedies as a secured party
with respect to the Collateral under the Uniform Commercial Code.

      D. The Secured Party desires to accept the Collateral in partial
satisfaction of all amounts due under the Debentures.

                                                     AGREEMENT

      It is agreed as follows:

warranties of the Debtor and Secured Party contained herein and subject to the

accept the Collateral in satisfaction of $35,555.00 of principal and interest
obligations secured under the Debentures; and (ii) Debtor has no objections to
Secured Party accepting the Collateral in satisfaction of $35,555.00 of
principal and interest obligations under the Debentures and agrees to waive any
and all notice periods under the applicable Uniform Commercial Code and further
agrees that it will not seek to redeem the Collateral prior to Closing.

      2. CLOSING.

            2.1 Date and Time. Subject to all of the terms and conditions set

            2.2 Deliveries by Secured Party. The Secured Party shall deliver to
the Debtor a written acknowledgement that the Debtor has satisfied $35,555 of

Party certificates representing the Membership Interest which are either duly

operating agreement of Well Renewal evidencing the assignment of the Membership
Interest to the Secured Party.

      3. COVENANTS. Each party hereto will, before, at, and after the Closing,
execute and deliver such instruments and take such other actions as the other
party or parties, as the case may be, may reasonably require in order to carry
out the intent of this Agreement. Without limiting the generality of the
foregoing, at any time after the Closing, at the request of Well Renewal or the
Secured Party, and without further consideration, the Debtor will execute and
deliver such instruments of sale, transfer, conveyance, assignment and
confirmation and take such action as Well Renewal or the Secured Party may

      THIS SECURITIES PURCHASE AGREEMENT is made as of the 7th day of October

"Company") and Lothian Oil Inc., a Delaware corporation (the "Investor").

      WHEREAS, the Investor has indicated a desire to purchase shares of the
Company's common stock, par value $0.001 per share, ("Common Stock") pursuant to
the terms of this Agreement.

      WHEREAS, the Company has indicated a desire to sell the Newly Issued

      WHEREAS, the Company and the Investor have agreed that this Agreement
shall constitute the entire understanding and agreement among the parties with

      THEREFORE the Company and the Investor (collectively sometimes referred to
as the Parties) agree as follows:

1. PURCHASE AND SALE OF SECURITIES.

      1.1. SALE AND ISSUANCE OF SECURITIES. Subject to the terms and conditions
of this Agreement, the Company agrees to sell to the Investor and the Investor
agrees to purchase from the Company a total of 3,280,000 Shares (the "Newly
Issued Shares") for an aggregate purchase price of $3,444,000, or $1.05 per
share, in cash. Subject to the terms and conditions of this Agreement, including
the Shareholder Approval Requirements set forth at Section 1.2 below, the

purchase of the Company's Common Stock: (i) a warrant for the purchase of
2,860,000 shares at a purchase price of $1.05 per share; (ii) a warrant for the
purchase of 3,000,000 shares at a price of $1.12. per share; and (iii) a warrant

Shares, the exercise price for the Warrants, the number of Newly Issued Shares
to be purchased hereunder and the number of shares of Common Stock obtainable
upon exercise of the Warrants shall be subject to adjustment if the Company (i)
at any time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, in which case the purchase price for the Newly Issued
Shares and the exercise price for the Warrants in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Newly Issued
Shares to be purchased hereunder and the number of shares of Common Stock
obtainable upon exercise of the Warrants shall be proportionately increased or
(ii) if the Company at any time combines (by reverse stock split or otherwise)
one or more classes of its outstanding shares of Common Stock into a smaller
number of shares, the purchase price for the Newly Issued Shares and the
exercise price for the Warrants in effect immediately prior to such combination
shall be proportionately increased and the number of Newly Issued Shares to be
purchased hereunder and the number of shares of Common Stock obtainable upon
exercise of the Warrants shall be proportionately decreased.

      1.2. SHAREHOLDER APPROVAL REQUIREMENTS. The Parties acknowledge that,
pursuant to sections (i)(1)(B) and (i)(1)(D)(ii) of Rule 4350 of the Nasdaq

must be approved by the issuer's shareholders (the "Shareholder Approval
Requirements"). The Parties acknowledge that the Company must comply with the
Shareholder Approval Requirements prior to selling the Newly Issued Shares and
issuing the Warrants. The Company's failure to obtain shareholder approval in
accordance with the Shareholder Approval Requirements shall not constitute a
breach of this Agreement. The Parties agree that if shareholder approval is not

below. The Company's proxy statement relative to this transaction is attached
hereto as Exhibit B (the "Proxy Statement").

Issued Shares in accordance with this Agreement.

Shares and Warrants (the "Closing") shall be held as soon as practicable, but in

3. REPRESENTATIONS AND WARRANTIES OF THE INVESTOR. The Investor hereby
represents and warrants that:

      3.1. ORGANIZATION, GOOD STANDING, POWER AND RIGHTS TO ACQUIRE STOCK. The
Investor is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware and has all requisite corporate power
and authority to enter into the transaction contemplated by this Agreement. The
Investor is duly qualified to transact business and is in good standing in the
States of Delaware and New York.

      3.2. AUTHORIZATION. This Agreement constitutes the valid and legally
binding obligation of the Investor, enforceable in accordance with its terms,
subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors and by general principles of equity.

      3.3. INVESTIGATION. The Investor acknowledges that it has had an
opportunity to discuss the business and affairs of the Company with the
Company's President, Walter G. Mize. The Investor further acknowledges having
had access to information about the Company that it has requested or considers
necessary for purposes of purchasing the Newly Issued Shares, including the
Company's SEC Documents and the exhibits thereto. The foregoing, however, does
not limit or modify the representations and warranties of the Company in Section

term is defined in Regulation D adopted by the SEC.

                                       7
<PAGE>

      3.5. PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with the
Investor in reliance upon the Investor's representation to the Company, which by
the Investor's execution of this Agreement the Investor hereby confirms, that
the Newly Issued Shares and the Warrants will be acquired for investment for the
Investor's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof other than in conformity with the Act
and the rules and regulations promulgated thereunder, and that the Investor has
no present intention of selling, granting any participation in, or otherwise
distributing the same, other than a transfer to a nominee holder or a
majority-owned affiliate.

      3.6. RESTRICTED SECURITIES. The Investor understands that the Newly Issued
Shares it is purchasing, along with the Warrants and the Common Stock underlying
the Warrants, are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances. In this connection, the Investor
represents that it is familiar with Rule 144 promulgated by the Securities and
Exchange Commission, as presently in effect, and understands the resale
limitations imposed thereby and by the Act.

      3.7. AUTHORIZATIONS. All authorizations, approvals or permits, if any, of
any governmental authority or regulatory body that are required to be obtained
by the Investor in connection with the lawful issuance and sale of the Newly
Issued Shares and the Warrants pursuant to this Agreement have been duly
obtained and shall be effective on and as of the Closing.

      3.8. BROKER'S OR FINDERS' FEE. The Investor has not incurred, nor will it
incur, directly or indirectly, any liability for brokerage or finders' fees or
agents' commissions or investment bankers' fees or any similar charges in
connection with the transaction contemplated by this Agreement.

      3.9. LEGENDS. It is understood that the certificates evidencing the Newly
Issued Shares, the Warrants and the Common Stock underlying the Warrants may
bear a legend in substantially the following form:

      "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE,
      PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN
      EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF
      COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED
      UNDER THE ACT."

      3.10 USA PATRIOT ACT REPRESENTATIONS.

            (a) The Investor represents and warrants that the proposed
      investment in the Newly Issued Shares that is being made on its own behalf
      does not directly or indirectly contravene United States federal, state,
      local or international laws or regulations applicable to the Investor,
      including anti-money laundering laws (a "Prohibited Investment").

            (b) Federal regulations and Executive Orders administered by the
      U.S. Treasury Department's Office of Foreign Assets Control ("OFAC")
      prohibit, among other things, the engagement in transactions with, and the
      provision of services to, certain foreign countries, territories, entities
      and individuals. The lists of OFAC prohibited countries, territories,
      persons and entities can be found on the OFAC website at
      www.treas.gov/ofac. The Investor hereby represents and warrants that the
      Investor is not a country, territory, person or entity named on an OFAC
      list, nor is the Investor an entity with whom dealings are prohibited
      under any OFAC regulations.

            (c) The Investor agrees promptly to notify the Company should the
      Investor become aware of any change in the information set forth in this
      Section 3.10. The Investor is advised that, by law, the Company may be
      obligated to "freeze the account" of the Investor, either by prohibiting
      additional capital contributions, declining any withdrawal requests and/or
      segregating the assets in the Investor's account in compliance with
      governmental regulations, and the Company may also be required to report
      such action and to disclose the Investor's identity to OFAC or other
      government agencies.

            (d) The Investor agrees to indemnify and hold harmless the Company,
      its affiliates, their respective directors, officers, members, managers,
      partners, shareholders, employees, agents and representatives (each, an
      "Indemnitee") from and against any and all losses, liabilities, damages,
      penalties, costs, fees and expenses (including legal fees and
      disbursements) (collectively, "Damages") which may result, directly or
      indirectly, from the Investor's misrepresentations or misstatements
      contained herein or breaches hereof.

            (e) The Investor understands and agrees that, notwithstanding
      anything to the contrary contained in any document (including any
      ancillary agreements) if, following the Investor's investment in the Newly
      Issued Shares, it is discovered that the investment is or has become a
      Prohibited Investment, such investment may immediately be redeemed by the
      Company or otherwise be subject to the remedies required by law, and the
      Investor shall have no claim against any Indemnitee for any form of
      Damages as a result of such forced redemption or other action.

            (f) Upon the written request from the Company, the Investor agrees
      to provide all information to the Company to enable the Company to comply
      with all applicable anti-money laundering statutes, rules, regulations and
      policies. The Investor understands and agrees that the Company may release
      confidential information about the Investor to any person if the Company,
      in its sole discretion, determines that such disclosure is necessary to
      comply with applicable statutes, rules, regulations and policies.

      shall any option, warrant, call, right, commitment or agreement (other
      than this Agreement) of any character be granted or made by the Company
      relating to its authorized or issued Common Stock; nor shall the Company
      issue, grant or sell any securities or obligations convertible into or
      exchangeable for Common Stock.

            (c) The Company will not take, agree to take, or knowingly permit to
      be taken any action, nor do or knowingly permit to be done anything in the
      conduct of the business of the Company or otherwise, which would be
      contrary to or in breach of any of the terms or provisions of this
      Agreement, or which would cause any of the Company's representations and
      warranties contained herein to be or become untrue in any material respect
      at the Closing Date. The Company is in the process of amending its
      Articles of Incorporation and its bylaws, as disclosed to the Investor,

      contributions to or investments in, any other individual, firm or
      corporation.

      other contract with any of its management personnel or make, adopt, alter,
      revise, or amend any pension, bonus, profit-sharing or other employee
      benefit plan, or grant any salary increase or bonus to any person.

            (f) The Company shall not authorize, recommend or propose any
      merger, consolidation, acquisition of assets, disposition of assets,
      material change in its capitalization or any comparable event, not in the
      ordinary course of business or in furtherance of the transactions
      contemplated hereby (in each case, other than the transactions
      contemplated hereby and transactions as to which written notice has been
      given to the other companies prior to the date hereof).

officers, directors, employees and agents and each person, if any, who controls
Investor within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act harmless from and against any and all liabilities, losses,
claims, costs, expenses, damages and judgments (including, without limitation,
any legal or other expenses incurred in connection with investigating or
defending any matter, including any action, that could give rise to such
liabilities, losses, claims, costs, expenses, damages and judgments)
(collectively, the "Losses") resulting from or arising out of any breach of any
representation, warranty, or non-performance of any covenant or agreement on the
part of the Company contained in this Agreement or in any statement or
certificate furnished or to be furnished by the Company pursuant hereto or in
connection with the transactions contemplated hereby; and

      7.2 Investor hereby agrees to indemnify and hold the Company, its
officers, directors, employees and agents and each person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act harmless from and against any and all Losses resulting from

                                       13
<PAGE>

      7.3 In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7.1 or 7.2 (the
"Indemnified Party"), the Indemnified Party shall promptly notify the person
against whom such indemnity may be sought (the "Indemnifying Party") in writing.
A delay in giving notice shall only relieve the Indemnifying Party of liability
to the extent the Indemnifying Party suffers actual prejudice because of the
delay. The Indemnifying Party shall have the right, at its option and expense,
to participate in the defense of such a proceeding or claim, but not to control
the defense, negotiation or settlement thereof, which control shall at all times
rest with the Indemnified Party, unless the proceeding or claim involves only
money damages, not an injunction or other equitable relief, and unless the
Indemnifying Party:

            (a) irrevocably acknowledges in writing complete responsibility for
      and agrees to indemnify the Indemnified Party, and

            (b) furnishes satisfactory evidence of the financial ability to
      indemnify the Indemnified Party,

in which case the Indemnifying Party may assume such control through counsel of
its choice and at its expense, but the Indemnified Party shall continue to have
the right to be represented, at its own expense, by counsel of its choice in
connection with the defense of such a proceeding or claim. If the Indemnifying
Party does not assume control of the defense of such a proceeding or claim, (i)
the entire defense of the proceeding or claim by the Indemnified Party, (ii) any
settlement made by the Indemnified Party, and (iii) any judgment entered in the
proceeding or claim shall be deemed to have been consented to by, and shall be
binding on, the Indemnifying Party as fully as though it alone had assumed the
defense thereof and a judgment had been entered in the proceeding or claim in
the amount of such settlement or judgment, except that the right of the
Indemnifying Party to contest the right of the Indemnified Party to
indemnification under the Agreement with respect to the proceeding or claim
shall not be extinguished. If the Indemnifying Party does assume control of the
defense of such a proceeding or claim, it will not, without the prior written
consent of the Indemnified Party settle the proceeding or claim or consent to
entry of any judgment relating thereto which does not include as an
unconditional term thereof the giving by the claimant to the Indemnified Party a
release from all liability in respect of the proceeding or claim. The Parties
hereto agree to cooperate fully with each other in connection with the defense,
negotiation or settlement of any such proceeding or claim.

8. OTHER CLOSING MATTERS.

      8.1. REPAYMENT OF ALMAC FINANCIAL CORPORATION. Prior to or at the Closing,
Almac Financial Corporation will provide the Escrow Agent with a demand for

terminate is not in material breach or default of this Agreement. In the event
of such termination and abandonment, neither the Company nor the Investor (or
any of their respective directors or officers) shall have any liability or
further obligations to any other party to this Agreement, except that nothing
herein will relieve any party from liability for any willful breach of this
Agreement.

      9.2 GOVERNING LAW. This Agreement shall be governed in all respects by the

substituted or additional securities which are by reason of any stock split,

agreements set forth in this Agreement to the same extent the Newly Issued
Shares are at such time covered by such provisions.

      9.4. SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding

and agreement among the Parties with regard to the subject matter hereof.

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR THE SECURITIES LAWS OF ANY
STATE OF THE UNITED STATES. THE SECURITIES EVIDENCED BY THIS CERTIFICATE MAY NOT
BE OFFERED, SOLD OR TRANSFERRED FOR VALUE, DIRECTLY OR INDIRECTLY, IN THE
ABSENCE OF SUCH REGISTRATION UNDER THE ACT AND QUALIFICATION UNDER APPLICABLE
STATE LAWS, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT AND
QUALIFICATION UNDER APPLICABLE STATE LAWS, THE AVAILABILITY OF WHICH IS TO BE

                           UNITED HERITAGE CORPORATION

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

Date of Issuance: October ____, 2005                       Certificate No. W-___

      FOR VALUE RECEIVED, United Heritage Corporation, a Utah corporation (the
"Company"), hereby grants to LOTHIAN OIL INC. or its registered assigns (the
"Registered Holder") the right to purchase from the Company ( ) shares of
Warrant Stock at a price per share of $________ (as adjusted from rime to time
hereunder, the "Exercise Price"). This Warrant is issued pursuant to the terms
of that certain Securities Purchase Agreement, dated of even date herewith (as
amended, supplemented or otherwise modified from time to time, the "Purchase
Agreement"). Certain capitalized terms used herein are defined in Section 3
hereof. The amount and kind of securities obtainable pursuant to the rights
granted hereunder and the purchase price for such securities are subject to
adjustment pursuant to the provisions contained in this Warrant.

      This Warrant is subject to the following provisions:

      (i) Exercise of Warrant.

1. Exercise Period. Subject to paragraph lB hereof, the Registered Holder may
exercise, in whole or in part (but not as to a fractional share of Warrant
Stock), the purchase rights represented by this Warrant at any time and from
time to time after the Date of Issuance to and including the fifth anniversary
of the Date of Issuance (the "Exercise Period").

2. Exercise Procedure.

            (a) This Warrant shall be deemed to have been exercised when the
      Company has received all of the following items (the "Exercise Time")

                                       18
<PAGE>

            (a) a completed Exercise Agreement, as described in paragraph lC
      below, executed by the Person exercising all or part of the purchase
      rights represented by this Warrant (the "Purchaser");

            (b) this Warrant; and

            (c) either (1) a check payable to the Company in an amount equal to
      the product of the Exercise Price multiplied by the number of shares of
      Warrant Stock being purchased upon such exercise (the "Aggregate Exercise
      Price"), (2) the surrender to the Company of debt or equity securities of
      the Company or any of its wholly-owned Subsidiaries having a Market Price
      equal to the Aggregate Exercise Price of the Warrant Stock being purchased
      upon such exercise (provided that for purposes of this subparagraph, the
      Market Price of any note or other debt security or any preferred stock
      shall be deemed to be equal to the aggregate outstanding principal amount
      or liquidation value thereof plus all accrued and unpaid interest thereon
      or accrued or declared and unpaid dividends thereon) or (3) a written
      notice to the Company that the Purchaser is exercising the Warrant (or a
      portion thereof) by authorizing the Company to withhold from issuance a
      number of shares of Warrant Stock issuable upon such exercise of the
      Warrant which when multiplied by the Market Price of the Warrant Stock is
      equal to the Aggregate Exercise Price (and such withheld shares shall no
      longer be issuable under this Warrant).

            (b) Certificates for shares of Warrant Stock purchased upon exercise
      of this Warrant shall be delivered by the Company to the Purchaser within
      five business days after the date of the Exercise Time. Unless this
      Warrant has expired or all of the purchase rights represented hereby have
      been exercised, the Company shall prepare a new Warrant, substantially
      identical hereto, representing the rights formerly represented by this
      Warrant which have not expired or been exercised and shall, within such
      five-day period, deliver such new Warrant to the Person designated for
      delivery in the Exercise Agreement.

            (c) The Warrant Stock issuable upon the exercise of this Warrant
      shall be deemed to have been issued to the Purchaser at the Exercise Time,
      and the Purchaser shall be deemed for all purposes to have become the
      record holder of such Warrant Stock at the Exercise Time.

            (d) The issuance of certificates for shares of Warrant Stock upon
      exercise of this Warrant shall be made without charge to the Registered
      Holder or the Purchaser for any issuance tax in respect thereof or other
      cost incurred by the Company in connection with such exercise and the
      related issuance of shares of Warrant Stock. Each share of Warrant Stock
      issuable upon exercise of this Warrant shall, upon payment of the Exercise
      Price therefor, be fully paid and nonassessable and free from all liens
      and charges with respect to the issuance thereof.

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

                                       19
<PAGE>

            (f) The Company shall at all times reserve and keep available out of
      its authorized but unissued shares of Common Stock, solely for the purpose
      of issuance upon the exercise of this Warrant, such number of shares of
      Warrant Stock issuable upon the exercise of this Warrant. The Company
      shall take all such actions as may be necessary to assure that all such
      shares of Warrant Stock may be so issued without violation of any
      applicable law or governmental regulation or any requirements of any
      domestic securities exchange upon which shares of Warrant Stock may be
      listed (except for official notice of issuance which shall be immediately
      delivered by the Company upon each such issuance). The Company shall not
      take any action which would cause the number of authorized but unissued
      shares of Warrant Stock to be less than the number of such shares required
      to be reserved hereunder for issuance upon exercise of this Warrant.

3. Exercise Agreement. Upon any exercise of this Warrant, the Exercise Agreement
shall be substantially in the form set forth in Annex I hereto, except that if
the shares of Warrant Stock are not to be issued in the name of the Person in
whose name this Warrant is registered, the Exercise Agreement shall also state
the name of the Person to whom the certificates for the shares of Warrant Stock
are to be issued, and if the number of shares of Warrant Stock to be issued does
not include all the shares of Warrant Stock purchasable hereunder, it shall also
state the name of the Person to whom a new Warrant for the unexercised portion
of the rights hereunder is to be delivered. Such Exercise Agreement shall be
dated the actual date of execution thereof.

4. Fractional Shares. If a fractional share of Warrant Stock would, but for the
provisions of paragraph 1A, be issuable upon exercise of the rights represented
by this Warrant, the Company shall, within five business days after the date of
the Exercise Time, deliver to the Purchaser a check payable to the Purchaser in
lieu of such fractional share in an amount equal to the difference between the
Market Price of such fractional share as of the date of the Exercise Time and
the Exercise Price of such fractional share.

5. Restrictive Legend. Unless registered under the Securities Act of 1933, as
amended (the "Act"), each certificate for Warrant Stock purchased upon exercise
of this Warrant shall bear a legend as follows:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR APPLICABLE STATE LAW AND
MAY NOT BE OFFERED FOR SALE, SOLD OR OTHERWISE TRANSFERRED PLEDGED OR
HYPOTHECATED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT
TO SUCH SECURITIES, OR DELIVERY OF AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT SUCH OFFER, SALE OR
TRANSFER, PLEDGE OR HYPOTHECATION IS EXEMPT FROM REGISTRATION OR OTHERWISE IN
COMPLIANCE WITH THE ACT AND APPLICABLE STATE LAW.

                                       20
<PAGE>

         (ii) Adjustment of Exercise Price and Number of Shares. The Exercise
Price shall be subject to adjustment from time to time as provided in this
Section 2, and the number of shares of Warrant Stock obtainable upon exercise of
this Warrant shall be subject to adjustment from time to time as provided in
this Section 2.

1. Subdivision or Combination of Common Stock. If the Company at any time
subdivides (by any stock split, stock dividend, recapitalization or otherwise)
one or more classes of its outstanding shares of Common Stock into a greater
number of shares, the Exercise Price in effect immediately prior to such
subdivision shall be proportionately reduced and the number of shares of Warrant
Stock obtainable upon exercise of this Warrant shall be proportionately
increased. If the Company at any time combines (by reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of shares of
Warrant Stock obtainable upon exercise of this Warrant shall be proportionately
decreased.

2. Notices. Promptly following any adjustment of the Exercise Price, the Company
shall give written notice thereof to the Registered Holder, setting forth in
reasonable detail and certifying the calculation of such adjustment.

      (iii) Definitions. The following terms have meanings set forth below:

            "Common Stock" means, collectively, the Company's Common Stock and
any capital stock of any class of the Company hereafter authorized which is not
limited to a fixed sum or percentage of par or stated value in respect to the
rights of the holders thereof to participate in dividends or in the distribution
of assets upon any liquidation, dissolution or winding up of the Company.

            "Market Price" means as to any security the average of the closing
prices of such security's sales on all domestic securities exchanges on which
such security may at the time be listed, or, if there have been no sales on any
such exchange on any day, the average of the highest bid and lowest asked prices
on all such exchanges at the end of such day, or, if on any day such security is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 P.M., New York time, on such day, or, if on any day
such security is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of 21 days
consisting of the day as of which "Market Price" is being determined and the 20
consecutive business days prior to such day; provided that if such security is
listed on any domestic securities exchange the term "business days" as used in
this sentence means business days on which such exchange is open for trading. If
at any time such security is not listed on any domestic securities exchange or
quoted in the NASDAQ System or the domestic over-the-counter market, the "Market
Price" shall be the fair value thereof determined jointly by the Company and the
Registered Holders; provided that if such parties are unable to reach agreement
within a reasonable period of time, such fair value shall be determined by an
appraiser selected by the Company and approved by the Registered Holder (such
approval not to be unreasonably withheld). The determination of such appraiser
shall be final and binding on the Company and the Registered Holder, and the
fees and expenses of such appraiser shall be paid by the Company.

                                       21
<PAGE>

            "Person" means an individual, a partnership, a joint venture, a
corporation, a limited liability company, a trust, an unincorporated
organization and a government or any department or agency thereof.

            "Warrant Stock" means the Company's Common Stock, par value $0.001
per share.

            Other capitalized terms used in this Warrant but not defined herein
shall have the meanings set forth in the Purchase Agreement.

      (iv) Registration Rights.

1. "Piggy-Back" Registration. The Registered Holder of this Warrant shall have
the right to include all or any portion of this Warrant requested by the
Registered Holder and all of the securities underlying such Warrant, including
the Warrant Stock underlying this Warrant (collectively, the "Registrable
Securities"), as part of any registration statement proposed to be filed by the
Company with the Securities and Exchange Commission for the purpose of
registering any of its Common Stock for its own or its officers', directors', or
shareholders' accounts under the Act for a public offering for cash (other than
in connection with a transaction contemplated by Rule 145(a) promulgated under
the Act or pursuant to Form S-8); provided that this Warrant has been exercised,
or is exercisable prior to the closing of such registration.

2. Terms. The Company shall bear all fees and expenses attendant upon
registering the Registrable Securities, but the Registered Holder shall pay any
and all underwriting commissions and the expenses of any legal counsel selected
by the Registered Holder to represent it in connection with the sale of the
Registrable Securities. In the event of such a proposed registration, the
Company shall furnish the Registered Holder of outstanding Registrable
Securities with not less than forty-five (45) days' written notice thereof prior
to the proposed date of filing of such registration statement. Such notice to
the Registered Holder shall continue to be given for each registration statement
filed by the Company until such time as all of the Registrable Securities have
been registered. The Registered Holder of the Registrable Securities shall
exercise the "piggy-back" rights provided for herein by giving written notice,
within thirty (30) days of the receipt of the Company's notice of its intention
to file a registration statement. The Company shall have the absolute right to
withdraw or cease to prepare or file any registration statement for any offering
referred to in this Section 5 without any obligation or liability to any
Registered Holder.

3. Reduction in Registration Rights. Notwithstanding 5B above, if any managing
underwriter of the securities being offered pursuant to any registration
statement under this Section 4 advises the Company in writing that, in its
opinion, the number of shares to be sold by persons other than the Company would
materially and adversely affect such offering, or the timing thereof, then the
Company shall reduce, pro rata (based upon the number of shares requested to be
included by the Company's officers', directors', shareholders' and all other
securities sought to be registered pursuant to the exercise of contractual
rights comparable to the rights granted in this Section 5) the number of
Registrable Securities to a number deemed satisfactory by such managing
underwriter.

                                       22
<PAGE>

4. Lock-up. Further in the event that any managing underwriter of the securities
being offered pursuant to any registration statement under this Section 5
requires, as a condition of including for registration shares belonging to the
Company's officers, directors, shareholders, that such officers, directors and
shareholders agree to delay the offering and sale of such registered securities
for a period of time (the "Lock-Up Period"), the Registered Holder hereof shall
agree to such Lock-Up Period, provided that such Lock-Up be on the same terms
and conditions as that of the Company's officers, directors and other
shareholders.

5. Limitations. Each Registered Holder shall be entitled to have its Registrable
Securities included in up to three (3) piggy-back registrations pursuant to this
Section 5, provided that, if all of the Registrable Securities are not
registered due to the provisions of Section 5C hereof, then the limitations
contained herein shall not be effective.

6. Indemnification.

      (i) In the event of any registration of any of the Registered Holder's
Registrable Securities under this Section 5, the Company shall indemnify and
hold harmless the Registered Holder, the Registered Holder's directors,
officers, and each entity or person controlling Registered Holder within the
meaning of Section 15 of the Securities Act, if any, with respect to which such
registration, qualification or compliance has been effected pursuant to this
Section 5, and each underwriter, if any, and each entity or person who controls
any underwriter within the meaning of Section 15 of the Securities Act, against
all expenses, claims, losses, damages and liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, or any violation by Company of any rule or regulation
promulgated under the Securities Act applicable to Company and relating to
action or inaction required of Company in connection with any such Registration,
qualification or compliance, and shall reimburse Registered Holder, each of
Registered Holder's directors, officers, employees and agents, and each entity
or person controlling Registered Holder, each such underwriter and each entity
or person who controls any such underwriter, for any legal and any other
expenses reasonably incurred in connection with investigating, preparing or
defending any such claim, loss, damage, liability or action, provided that
Company shall not be liable to Registered Holder or an underwriter in any such
case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based solely on any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
written information furnished to Company by an instrument duly executed by
Registered Holder or an underwriter and stated to be specifically for use
therein.

                                       23
<PAGE>

      (ii) Registered Holder shall, if Registrable Securities are included in
the securities as to which a Registration, qualification or compliance has been
effected pursuant to this Section 5, indemnify Company, each of its directors
and officers, each underwriter, if any, of Company's securities covered by such
registration, qualification or compliance, each entity or person who controls
Company or such underwriter within the meaning of Section 15 of the Securities
Act, and each of its directors, officers, employees and agents, against all
expenses, claims, losses, damages and liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such Registration,
qualification or compliance or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances in which they were
made, not misleading, or any violation by Company of any rule or regulation
promulgated under the Securities Act applicable to Company in connection with
any such Registration, qualification, or compliance, and shall reimburse
Company, such directors, officers, employees, agents, underwriters or control
persons for any legal or any other expenses reasonably incurred in connection
with investigating, preparing or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to Company by an instrument duly
executed by Registered Holder and stated to be specifically for use therein;
provided, however, that Registered Holder's obligations hereunder shall be
limited to an amount equal to the proceeds Registered Holder received for Shares
sold as contemplated herein.

      (iii) Each party entitled to indemnification under this section (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at its own
expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this section unless such failure resulted in actual detriment
to the Indemnifying Party. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party a release from all liability in respect of such claim
or litigation.

                                       24
<PAGE>

      (iv) If the indemnification provided for in this section is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense, as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission

7. No Voting Rights; Limitations of Liability. Except as otherwise set forth in
this Warrant, this Warrant shall not entitle the holder hereof to any voting
rights or other rights as a stockholder of the Company. No provision hereof, in
the absence of affirmative action by the Registered Holder to purchase Warrant
Stock, and no enumeration herein of the rights or privileges of the Registered
Holder shall give rise to any liability of such holder for the Exercise Price of
Warrant Stock acquirable by exercise hereof or as a stockholder of the Company.

8. Transfers, etc. Subject to the transfer conditions referred to in the legend
endorsed hereon, this Warrant and all rights hereunder are transferable, in
whole or in part, without charge to the Registered Holder, upon surrender of
this Warrant with a properly executed Assignment (in the form of Annex II
hereto) at the principal office of the Company.

9. Warrant Exchangeable for Different Denominations. This Warrant is
exchangeable, upon the surrender hereof by the Registered Holder at the
principal office of the Company, for new Warrants of like tenor representing in
the aggregate the purchase rights hereunder, and each of such new Warrants shall
represent such portion of such rights as is designated by the Registered Holder
at the time of such surrender. The date the Company initially issues this
Warrant shall be deemed to be the "Date of Issuance" hereof regardless of the
number of times new certificates representing the unexpired and unexercised
rights formerly represented by this Warrant shall be issued. All Warrants
representing portions of the rights hereunder are referred to herein as the
"Warrants."

10. Replacement. Upon receipt of evidence reasonably satisfactory to the Company
(an affidavit of the Registered Holder shall be satisfactory) of the ownership
and the loss, theft, destruction or mutilation of any certificate evidencing
this Warrant, and in the case of any such loss, theft or destruction, upon
receipt of indemnity reasonably satisfactory to the Company (provided that if
the holder is a financial institution or other institutional investor its own
agreement shall be satisfactory), or, in the case of any such mutilation upon
surrender of such certificate, the Company shall (at its expense) execute and
deliver in lieu of such certificate a new certificate of like kind representing
the same rights represented by such lost; stolen, destroyed or mutilated
certificate and dated the date of such lost, stolen, destroyed or mutilated
certificate.

                                       25

11. Notices. Except as otherwise expressly provided herein, all notices referred
to in this Warrant shall be in writing and shall be delivered personally or sent
