      2. BUYER'S REPRESENTATIONS AND WARRANTIES.

      Each Buyer represents and warrants, severally and not jointly, that:

            (a) Investment Purpose. Each Buyer is acquiring the Convertible
Debentures and, upon conversion of Convertible Debentures, the Buyer will
acquire the Conversion Shares then issuable, for its own account for investment
only and not with a view towards, or for resale in connection with, the public
sale or distribution thereof, except pursuant to sales registered or exempted
under the Securities Act; provided, however, that by making the representations
herein, such Buyer reserves the right to dispose of the Conversion Shares at any
time in accordance with or pursuant to an effective registration statement
covering such Conversion Shares or an available exemption under the Securities
Act.

            (b) Accredited Investor Status. Each Buyer is an "Accredited
Investor" as that term is defined in Rule 501(a)(3) of Regulation D.

            (c) Reliance on Exemptions. Each Buyer understands that the
Convertible Debentures are being offered and sold to it in reliance on specific
exemptions from the registration requirements of United States federal and state
securities laws and that the Company is relying in part upon the truth and
accuracy of, and such Buyer's compliance with, the representations, warranties,
agreements, acknowledgments and understandings of such Buyer set forth herein in
order to determine the availability of such exemptions and the eligibility of
such Buyer to acquire such securities.

            (d) Information. Each Buyer and its advisors (and his or, its
counsel), if any, have been furnished with all materials relating to the
business, finances and operations of the Company and information he deemed
material to making an informed investment decision regarding his purchase of the
Convertible Debentures and the Conversion Shares, which have been requested by
such Buyer. Each Buyer and its advisors, if any, have been afforded the
opportunity to ask questions of the Company and its management. Neither such
inquiries nor any other due diligence investigations conducted by such Buyer or
its advisors, if any, or its representatives shall modify, amend or affect such
Buyer's right to rely on the Company's representations and warranties contained
in Section 3 below. Each Buyer understands that its investment in the
Convertible Debentures and the Conversion Shares involves a high degree of risk.
Each Buyer is in a position regarding the Company, which, based upon employment,
family relationship or economic bargaining power, enabled and enables such Buyer
to obtain information from the Company in order to evaluate the merits and risks
of this investment. Each Buyer has sought such accounting, legal and tax advice,
as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Convertible Debentures and the Conversion
Shares.

investment in the Convertible Debentures or the Conversion Shares, nor have such
authorities passed upon or endorsed the merits of the offering of the
Convertible Debentures or the Conversion Shares.

            (f) Transfer or Resale. Each Buyer understands that except as
provided in the Investor Registration Rights Agreement: (i) the Convertible

reliance on Rule 144 under the Securities Act (or a successor rule thereto)

further, if Rule 144 is not applicable, any resale of such securities under
circumstances in which the seller (or the person through whom the sale is made)
may be deemed to be an underwriter (as that term is defined in the Securities
Act) may require compliance with some other exemption under the Securities Act
or the rules and regulations of the United States Securities and Exchange
Commission (the "SEC") thereunder; and (iii) neither the Company nor any other
person is under any obligation to register such securities under the Securities
Act or any state securities laws or to comply with the terms and conditions of
any exemption thereunder. The Company reserves the right to place stop transfer

            (g) Legends. Each Buyer understands that the certificates or other
instruments representing the Convertible Debentures and or the Conversion Shares
shall bear a restrictive legend in substantially the following form (and a stop
transfer order may be placed against transfer of such stock certificates):

      4. COVENANTS.

            (a) Best Efforts. Each party shall use its best efforts to timely
satisfy each of the conditions to be satisfied by it as provided in Sections 6
and 7 of this Agreement.

            (b) Form D. The Company agrees to file a Form D with respect to the
Conversion Shares as required under Regulation D and to provide a copy thereof
to each Buyer promptly after such filing. The Company shall, on or before each

necessary to qualify the Conversion Shares, or obtain an exemption for the
Conversion Shares for sale to the Buyers at the Closing pursuant to this
Agreement under applicable securities or "Blue Sky" laws of the states of the
United States, and shall provide evidence of any such action so taken to the
Buyers on or prior to the Closing Date.

            (c) Reporting Status. Until the earlier of (i) the date as of which
the Buyer(s) may sell all of the Conversion Shares without restriction pursuant
to Rule 144(k) promulgated under the Securities Act (or successor thereto), or
(ii) the date on which (A) the Buyer(s) shall have sold all the Conversion
Shares and (B) none of the Convertible Debentures are outstanding (the
"Registration Period"), the Company shall file in a timely manner all reports
required to be filed with the SEC pursuant to the Exchange Act and the
regulations of the SEC thereunder, and the Company shall not terminate its
status as an issuer required to file reports under the Exchange Act even if the
Exchange Act or the rules and regulations thereunder would otherwise permit such
termination.

<PAGE>

            (d) Use of Proceeds. The Company will use the proceeds from the sale
of the Convertible Debentures for general corporate and working capital
purposes.

            (e) Reservation of Shares. The Company shall take all action
reasonably necessary to at all times have authorized, and reserved for the
purpose of issuance, such number of shares of Common Stock as shall be necessary
to effect the issuance of the Conversion Shares. If at any time the Company does
not have available such shares of Common Stock as shall from time to time be
sufficient to effect the conversion of all of the Conversion Shares, the Company
shall call and hold a special meeting of the shareholders within thirty (30)
days of such occurrence, for the sole purpose of increasing the number of shares
authorized. The Company's management shall recommend to the shareholders to vote
in favor of increasing the number of shares of Common Stock authorized.
Management shall also vote all of its shares in favor of increasing the number
of authorized shares of Common Stock.

            (f) Listings or Quotation. The Company shall promptly secure the
listing or quotation of the Conversion Shares upon each national securities
exchange, automated quotation system or The National Association of Securities
Dealers Inc.'s Over-The-Counter Bulletin Board ("OTCBB") or other market, if
any, upon which shares of Common Stock are then listed or quoted (subject to
official notice of issuance) and shall use its best efforts to maintain, so long
as any other shares of Common Stock shall be so listed, such listing of all
Conversion Shares from time to time issuable under the terms of this Agreement.
The Company shall maintain the Common Stock's authorization for quotation on the
OTCBB.

            (g) Fees and Expenses. Each of the Company and the Buyer(s) shall
pay all costs and expenses incurred by such party in connection with the
negotiation, investigation, preparation, execution and delivery of the
Transaction Documents. The Company shall pay Corporate Strategies, Inc. a fee
equal to ten percent (10%) of the Purchase Price.

            (h) Corporate Existence. So long as any of the Convertible
Debentures remain outstanding, the Company shall not directly or indirectly
consummate any merger, reorganization, restructuring, reverse stock split
consolidation, sale of all or substantially all of the Company's assets or any
similar transaction or related transactions (each such transaction, an
"Organizational Change") unless, prior to the consummation an Organizational
Change, the Company obtains the written consent of each Buyer. In any such case,
the Company will make appropriate provision with respect to such holders' rights
and interests to insure that the provisions of this Section 4(h) will thereafter
be applicable to the Convertible Debentures.

            (i) Transactions With Affiliates. So long as any Convertible
Debentures are outstanding, the Company shall not, and shall cause each of its
subsidiaries not to, enter into, amend, modify or supplement, or permit any
subsidiary to enter into, amend, modify or supplement any agreement,
transaction, commitment, or arrangement with any of its or any subsidiary's
officers, directors, person who were officers or directors at any time during
the previous two (2) years, stockholders who beneficially own five percent (5%)
or more of the Common Stock, or Affiliates (as defined below) or with any
individual related by blood, marriage, or adoption to any such individual or
with any entity in which any such entity or individual owns a five percent (5%)
or more beneficial interest (each a "Related Party"), except for (a) customary
employment arrangements and benefit programs on reasonable terms, (b) any
investment in an Affiliate of the Company, (c) any agreement, transaction,
commitment, or arrangement on an arms-length basis on terms no less favorable
than terms which would have been obtainable from a person other than such
Related Party, (d) any agreement, transaction, commitment, or arrangement which
is approved by a majority of the disinterested directors of the Company; for
purposes hereof, any director who is also an officer of the Company or any
subsidiary of the Company shall not be a disinterested director with respect to
any such agreement, transaction, commitment, or arrangement. "Affiliate" for
purposes hereof means, with respect to any person or entity, another person or
entity that, directly or indirectly, (i) has a ten percent (10%) or more equity
interest in that person or entity, (ii) has ten percent (10%) or more common
ownership with that person or entity, (iii) controls that person or entity, or
(iv) shares common control with that person or entity. "Control" or "controls"
for purposes hereof means that a person or entity has the power, direct or
indirect, to conduct or govern the policies of another person or entity.

            (j) Transfer Agent. The Company covenants and agrees that, in the
event that the Company's agency relationship with the transfer agent should be
terminated for any reason prior to a date which is two (2) years after the
Closing Date, the Company shall immediately appoint a new transfer agent and
shall require that the new transfer agent execute and agree to be bound by the
terms of the Irrevocable Transfer Agent Instructions (as defined herein).

            (k) Restriction on Issuance of the Capital Stock. So long as any
Convertible Debentures are outstanding, the Company shall not, without the prior
written consent of the Buyer(s), (i) issue or sell shares of Common Stock or
Preferred Stock without consideration or for a consideration per share less than
the bid price of the Common Stock determined immediately prior to its issuance,
(ii) issue any warrant, option, right, contract, call, or other security
instrument granting the holder thereof, the right to acquire Common Stock
without consideration or for a consideration less than such Common Stock's Bid
Price value determined immediately prior to it's issuance, (iii) enter into any
security instrument granting the holder a security interest in any and all
assets of the Company, or (iv) file any registration statement on Form S-8.

            (l) Neither the Buyer(s) nor any of its affiliates have an open
short position in the Common Stock of the Company, and the Buyer(s) agrees that
it shall not, and that it will cause its affiliates not to, engage in any short
sales of or hedging transactions with respect to the Common Stock as long as any
Convertible Debenture or warrants to purchase the Warrant Shares shall remain
outstanding.
