Purchaser that, as of the Closing:

          (a) Organization and Standing.  The Company is a corporation duly
              -------------------------                                    
organized, in good standing and validly existing under the laws of the State of
Nevada and has requisite corporate power to own and operate its properties and
assets and carry on its business as presently conducted.

          (b) Authorization.  The execution, delivery and performance of this
              -------------                                                  
Agreement by the Company has been duly authorized by all requisite corporate
action, and this Agreement constitutes the legal, valid and binding obligation
of the Company enforceable in accordance with its terms, subject as to
enforcement of remedies to applicable bankruptcy, insolvency, reorganization or
similar laws relating to 

                                       1

 
or affecting the enforcement of creditors' rights. The execution, delivery and
performance of this Agreement, and the Warrant and compliance with the
provisions hereof and thereof by the Company does not conflict with, or result

both could result in a default) under, or result in the creation or imposition
of any lien pursuant to the terms of, the Articles of Incorporation or the
Bylaws of the Company.

          (c) Securities. The shares of Warrant Stock issued upon exercise of
              ----------                                                     
the Warrant will be validly issued, fully paid and non-assessable; provided,
however, that such securities shall be subject to restrictions on transfer under
applicable state or federal securities laws.

          4.  Purchaser Representations.  Purchaser represents and warrants to
              -------------------------                                       
the Company, with respect to both its purchase of the Warrant and the issuance
of Warrant Shares upon its exercise, that:

          (a) Company Affairs: Purchaser's Account:  Accredited Investor.
              ----------------------------------------------------------  
Purchaser is aware of the Company's business affairs and financial condition,
has had sufficient opportunity to ask questions of and receive answers from
representatives of the Company and has acquired sufficient information about the
Company to reach an informed and knowledgeable decision to purchase the Warrant.
Purchaser is purchasing the Warrant for investment for Purchaser's own account
only and not with a view to, or for resale in connection with, any
'distribution' thereof within the meaning of the Securities Act of 1933, as
amended (the 'Securities Act').  Purchaser is an 'accredited investor' as such
term is defined in Rule 501(a) of Regulation D under the Securities Act and has
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of investing in the Note, Warrant and the
securities issuable upon conversion or exercise thereof (collectively, the
'Securities'), including a complete loss of its investment.

          (b) Unregistered Securities.  Purchaser understands that neither the
              -----------------------                                         
Warrant nor any shares of Warrant Stock issued upon exercise thereof have been
registered under the Securities Act, by reason of a specific exemption therefrom
which depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

          (c) Holding Period: Legends.  Purchaser further acknowledges and
              -----------------------                                     
understands that the Warrant and any shares of Warrant Stock issued upon
exercise thereof must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is
available.  Purchaser understands that the Warrant and, when and if issued,
certificates evidencing the shares of Warrant Stock issuable upon exercise
thereof, will be imprinted with a legend that prohibits the transfer of such
Warrant or securities, unless they are registered or such registration is not
required in the opinion of legal counsel for the Company.

          (d) Restricted Securities.  Purchaser understands that the securities
              ---------------------                                            
it is purchasing 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 Securities Act only in certain limited circumstances.  In this connection,
Purchaser represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the
Securities Act.

          (e) No Market.  Purchaser further understands that, at the time
              ---------                                                  
Purchaser wishes to sell shares Warrant Stock issued upon exercise of the
Warrant, there may be no public market upon which to make such a sale, and that,
even if such a public market then exists, the Company may not be satisfying the
current public information requirements of Rule 144, and that, in such event,
Purchaser will be 

                                       2

 
precluded from selling such securities under Rule 144 even if any minimum
holding period has been satisfied; provided, however, that the Company shall use
its best efforts to satisfy the current public information requirements of Rule
144.

          5.  General Provisions.
