                            STOCK PURCHASE AGREEMENT

         This STOCK PURCHASE AGREEMENT ("Agreement") is dated June 18, 2003
between Richard Melnick ("Purchaser"), and HiEnergy Technologies, Inc., a
Delaware corporation ("Company").

1. PURCHASE AND SALE. Purchaser agrees to buy and the Company agrees to sell and
issue to Purchaser 300,000 shares of the Company's authorized and previously
unissued common stock, par value $0.001 per share (the "Shares"), at a price of
$0.33 1/3 per share, for an aggregate purchase price of $100,000 (the "Purchase
Price").

2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby makes the
following representations and warranties to the Purchaser:

        (A) REGISTERED OFFERING. The offer and sale of the Shares have been
        registered on a Form SB-2 registration statement, Registration No.
        333-101055 ("Registration Statement"), which Registration Statement has
        been declared effective by the Securities and Exchange Commission (the
        "Commission") and the Company has not received notice that the
        Commission has issued or intends to issue a stop order with respect to
        the Registration Statements or that the Commission otherwise has
        suspended or withdrawn the effectiveness of the Registration Statements,
        either temporarily or permanently, or intends or has threatened in
        writing to do so. The Company has delivered to Purchaser the prospectus
        that constitutes a part of the Registration Statement.

        (B) ORGANIZATION AND QUALIFICATION. The Company is a corporation duly
        incorporated, validly existing and in good standing under the laws of
        the State of Delaware with the requisite corporate power and authority
        to own and use its properties and assets and to carry on its business as
        currently conducted. The Company is duly qualified to conduct business
        and is in good standing as a foreign corporation or other entity in each
        jurisdiction in which the nature of the business conducted or property
        owned by it makes such qualification necessary.

        (C) AUTHORIZATION. The Company has the requisite corporate power and
        authority to enter into and to consummate the transactions contemplated
        by this Agreement and otherwise to carry out its obligations hereunder.
        The execution and delivery of this Agreement by the Company and the
        consummation of the transaction contemplated hereby have been duly
        authorized by all necessary action on the part of the Company and no
        further action is required by the Company or its shareholders for the
        Company to execute and consummate this Agreement and the transactions
        contemplated hereby. This Agreement has been duly executed by the
        Company and, when delivered in accordance with the terms hereof, and
        assuming the valid execution hereof by the Purchaser, will constitute
        the valid and binding obligation of the Company enforceable against the
        Company in accordance with its terms, except (a) as such enforceability
        may be limited by bankruptcy, insolvency, reorganization or similar laws
        affecting creditors' rights generally, (b) as enforceability of any
        indemnification and contribution provisions may

<PAGE>

        be limited under the federal and state securities laws and public
        policy, and (c) that the remedy of specific performance and injunctive
        and other forms of equitable relief may be subject to equitable defenses
        and to the discretion of the court before which any proceeding therefor
        may be brought.

        (D) NO CONFLICTS. The execution, delivery and performance of this
        Agreement by the Company and the consummation by the Company of the
        transactions contemplated hereby does not and will not: (i) conflict
        with or violate any provision of the Company's certificate of
        incorporation or bylaws (each as amended through the date hereof), or
        (ii) conflict with, or constitute a default (or an event which with
        notice or lapse of time or both would become a default) under, or give
        to others any rights of termination, amendment or acceleration (with or
        without notice, lapse of time or both) of, any material agreement or
        indebtedness to which the Company is a party or by which any material
        property or asset of the Company is bound or affected, or (iii) result
        in a violation of any law, rule, regulation, order, judgment, decree or
        other restriction of any court, governmental authority or stock market
        to which the Company or the Common Stock is subject. No assurance is
        intended as to the potential effects of the Company's Series A Preferred
        Stock Most Favored Nation provision.

        (E) ISSUANCE OF THE SHARES. The Shares are duly authorized and, when
        issued and paid for in accordance with the terms hereof, will be legally
        issued, fully paid and nonassessable, free and clear of all liens and
        encumbrances (other than any that are the result of any action or
        inaction of the Purchaser).

        (F) DISCLOSURE. Neither the Company nor any other Person acting on its
        behalf has provided the Purchaser or their agents or counsel with any
        information that constitutes or may, in the Company's opinion,
        constitute material non?public information.

3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser hereby
represents and warrants to the Company as follows:

        (A) VALIDITY. Upon the execution and delivery of this Agreement, and
        assuming the valid execution thereof by the Company, this Agreement
        shall constitute the valid and binding obligation of the Purchaser,
        enforceable against the Purchaser in accordance with its terms, except
        (a) as such enforceability may be limited by bankruptcy, insolvency,
        reorganization or similar laws affecting creditors' rights generally,
        (b) as enforceability of any indemnification and contribution provisions
        may be limited under the federal and state securities laws and public
        policy, and (c) that the remedy of specific performance and injunctive
        and other forms of equitable relief may be subject to equitable defenses
        and to the discretion of the court before which any proceeding therefor
        may be brought.

        (B) NO CONFLICTS. The execution, delivery and performance of this
        Agreement by the Purchaser and the consummation by the Purchaser of the
        transactions contemplated hereby does not and will not (i) conflict with
        or violate any provision of the Purchaser's or Company's certificate of
        incorporation or bylaws (each as amended through the date hereof), or
        (ii) conflict with, or constitute a default (or an event which with
        notice or

<PAGE>

        lapse of time or both would become a default) under, or give to others
        any rights of termination, amendment or acceleration (with or without
        notice, lapse of time or both) of, any material agreement or
        indebtedness to which the Purchaser is a party or by which any material
        property or asset of the Purchaser is bound or affected, or (iii) result
        in a violation of any order, judgment or decree of any court to which
        the Purchaser is subject.

        (C) INVESTMENT REPRESENTATION. The Purchaser is not party to any
        agreement or arrangement with respect to a disposition of Shares other
        than this Agreement. The Purchaser is not registered as a broker-dealer
        under the Exchange Act. The Purchaser is purchasing the Shares for the
        Purchaser's own account, for investment purposes only and not with a
        view to distribute or participate in a distribution thereof; provided,
        that the foregoing representation and warranty is not an agreement by
        the Purchaser to hold the Shares for any period of time.

4. PAYMENT. The parties are entering into the Escrow Agreement attached as
Exhibit A (the "Escrow Agreement"), and the Purchaser will wire funds prior to
the Closing Day to the Escrow Agent, as defined in the Escrow Agreement.
Purchaser, in its sole and absolute discretion, shall have until 12:00 noon
Eastern Time on the second (2nd) Trading Day following its transfer of funds to
the Escrow Agent to notify the Escrow Agent in writing of Purchaser's intention
to consummate the Purchase. If such notice is not received timely, the Escrow
agent shall promptly wire the payment back to the Purchaser, and this Agreement
shall be null and voice and of no force or effect whatsoever. If such notice is
received, the Seller shall notify its transfer agent within one (1) Trading Day
thereafter to deliver the Shares to the Purchaser. On the Closing Day: (x) the
Company will deliver to the Purchaser, via the Purchaser's DTC Account through
the Depository Trust Company DWAC system, the number of Shares set forth herein;
and (y) the Escrow Agent will deliver to the Company an amount in United States
dollars equal to the product of the number of Shares that it is acquiring,
multiplied by the Per Share Purchase Price for such Shares, via wire transfer of
immediately available funds to an account designated in writing by the Company
for such purpose. The term "Closing Day" shall mean the first date that the
Company can deliver the Shares, but not later than June 19, 2003.

5. COUNTERPARTS. This Agreement may be executed in two or more counterparts, all
of which shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to the
other party. This Agreement, once executed by a party, may be delivered to the
other party hereto by facsimile transmission of a copy of this Agreement bearing
the signature of the party so delivering this Agreement, which shall be deemed
fully valid and binding. The parties also agree to forward promptly their
original signature on a copy of this Agreement to the other party.

6. ENTIRE AGREEMENT. This Agreement contains the entire understanding of the
parties with respect to the matters covered herein and, except as specifically
set forth herein, neither the Company nor the Purchaser make any representation,
warranty, covenant or undertaking with respect to such matters. No provision of
this Agreement may be amended other than by an instrument in writing signed by
the Company and Purchaser.

7. SEVERABILITY. In the event that any provision of this Agreement shall be
determined to be invalid or unenforceable by any court of competent
jurisdiction, the remainder of this agreement shall not be affected thereby, and

enforceable to the full extent permitted by law.
