3.   REPRESENTATIONS OF THE COMPANY


         The Company represents and warrants to the Purchaser that, other than
as set forth on the Company Schedules attached hereto:

     a. ORGANIZATION. The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Nevada. Each of the
Company's subsidiaries, if any, is a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation. Each of the Company and its subsidiaries, if any, is duly
qualified as a foreign corporation in all jurisdictions in which the failure to
so qualify would have a material adverse effect on the Company and its
subsidiaries, taken as a whole. Schedule 3.a. lists all subsidiaries of the
Company and, except as noted therein, all of the outstanding capital stock of
all such subsidiaries is owned of record and beneficially by the Company. The
Company and its subsidiaries have all requisite corporate power and authority,
and hold all licenses, permits and other required authorizations from
governmental authorities, necessary to conduct their business as it is now being
conducted or proposed to be conducted and to own or lease their properties and
assets as they are now owned or held under lease.

     b. CAPITALIZATION. On the date hereof, the authorized capital of the
Company consists of 50,000,000 shares of Common Stock, par value US$0.001 per
share and 10,000,000 preferred stock, par value US$0.001 per share. On the
Closing Date, 968,384 shares of Common Stock are issued and outstanding and no
shares of Preferred Stock are issued or outstanding. Schedule 3.b. sets forth
all of the options, warrants and convertible securities of the Company, and any
other rights to acquire securities of the Company (collectively the "Derivative
Securities") which are (i) outstanding on the date hereof; (ii) will be
outstanding as of the Closing Date just before Closing; and (iii) will be
outstanding immediately after the Closing, including in each case: (i) the name
and class of such Derivative Securities; (ii) the issue date of such Derivative
Securities; (iii) the number of shares of Common Stock or Preferred Stock of the
Company into which such Derivative Securities are convertible as of the date
hereof; (iv) the conversion or exercise price or prices of such Derivative
Securities as of the date hereof; (v) the expiration date of any conversion or
exercise rights held by the owners of such Derivative Securities; and (vi) any
registration rights associated with such Derivative Securities. Schedule 3.b.
also sets forth all registration rights associated with or covering the



<PAGE>



Common Stock or Preferred Stock. All outstanding securities of the Company are
validly issued, fully paid and nonassessable. No stockholder of the Company is
entitled to any preemptive rights with respect to the purchase of or sale of any
securities by the Company. Except as contemplated herein, none of the shares of
capital stock of the Company is reserved for any purpose, and the Company is
neither subject to any obligation (contingent or otherwise), nor has any option,
to repurchase or otherwise acquire or retire any shares of its capital stock. No
antidilution adjustments with respect to the outstanding securities of the
Company will be triggered by the issuance of the securities contemplated hereby.

     c. CONCERNING THE COMPANY SHARES AND THE WARRANTS. The Securities, when
issued, will be duly and validly issued, fully paid and non-assessable, will be
free and clear of any liens imposed by or through the Company, will not be
subject to preemptive rights and will not subject the holder thereof to personal
liability by reason of being such a holder. There are currently no preemptive
rights of any stockholder of the Company, as such, to acquire any Security.

     d. REPORTING COMPANY STATUS. The Company's Common Stock is registered under
Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). The Company files reports with the Commission pursuant to Section 12
and/or 15(d) of the Exchange Act. The Company has complied in all material
respects with the filing requirements under either Section 13(a) or 15(d) of the
Exchange Act and the applicable rules and regulations of the Commission
promulgated thereunder, except that some of the filings were filed late.

     e. AUTHORIZED SHARES. The Company has available and has reserved a
sufficient number of authorized and unissued shares of Common Stock as may be
necessary to effect the issuance of the Company Shares and the exercise of the
Warrants. The Company understands and acknowledges the potentially dilutive
effect to the Common Stock of the issuance of shares of Common Stock upon the
exercise of the Warrants. The Company further acknowledges that its obligation
to issue shares of Common Stock upon exercise of the Warrants is absolute and
unconditional regardless of the dilutive effect such issuance may have on the
ownership interest of other stockholders of the Company and notwithstanding the
commencement any case under 11 U.S.C. 101 et seq. (the "Bankruptcy Code"). If
the Company becomes a debtor under the Bankruptcy Code, the Company hereby
waives to the fullest extent permitted any rights to relief it may have under 11
U.S.C. 362 in respect of the exercise of the Warrants. At the direction of the
Purchaser, the Company agrees, without cost or expense to the Purchaser, to take
or consent to any and all action necessary to effectuate relief under 11 U.S.C.
362.

     f. LEGALITY. The Company has the requisite corporate power and authority to
enter into this Agreement and the Registration Rights Agreement and to issue and
deliver the Warrants, Common Stock issuable upon the exercise of the Warrants
and the Company Shares.

     g. TRANSACTION AGREEMENTS. This Agreement, the Company Shares, the Warrants
and the Registration Rights Agreement (collectively, the "Primary Documents")
and the transactions contemplated hereby and thereby have been duly and validly
authorized by the Company; the Primary Documents have been duly executed and
delivered by the Company and are each the legal, valid and binding agreement of
the Company, enforceable in accordance with their respective terms, except to
the extent that enforcement of each agreement may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other



<PAGE>



similar laws now or hereafter in effect relating to creditors' rights generally
and to general principles of equity.

     h. NON-CONTRAVENTION. The execution and delivery of the Primary Documents,
and the consummation by the Company of the transactions contemplated hereby and
thereby, does not and will not (i) result in a violation of the Articles of
Incorporation or By-laws of the Company or its subsidiaries, or (ii) conflict
with, or constitute a default (or an event which with notice or lapse of time or
both could become a default) under, or give to others any rights of termination,
amendment or cancellation of, any agreement, indenture or instrument to which
the Company or any of its subsidiaries is a party, or result in a violation of
any law, rule, regulation, order, judgment or decree (foreign or domestic and
including federal and state securities laws and regulations) applicable to the
Company or any of its subsidiaries or by which any material property or asset of
the Company or any of its subsidiaries is bound or affected. Neither the filing
of the registration statement required to be filed by the Company pursuant to
the Registration Rights Agreement nor the offering or sale of the Securities as
contemplated by this Agreement gives rise to any rights, other than those which
have been waived or satisfied on or prior to the date hereof, for or relating to
the registration of any shares of the Common Stock..

     i. APPROVALS. No authorization, approval or consent of any court,
governmental body, regulatory agency, self-regulatory organization, stock
exchange or market or the stockholders of the Company is required to be obtained
by the Company for the entry into or the performance of any Primary Document.

     j. SEC DOCUMENTS, FINANCIAL STATEMENTS. The Company has filed all reports,
schedules, forms and statements required to be filed by it with the Commission
pursuant to the reporting requirements of the Exchange Act (the "SEC
Documents"). As of their respective dates, none of the SEC Documents contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The financial statements of the Company included in the SEC
Documents were prepared in accordance with U.S. generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise indicated in such financial statements or the notes thereto, or
(ii) in the case of unaudited interim statements, to the extent they may not
include footnotes or may be condensed or summary statements) and fairly present
in all material respects the consolidated financial position of the Company and
its consolidated subsidiaries and results of their operations and cash flows for
the periods covered thereby (subject, in the case of unaudited statements, to
normal year-end audit adjustments).

     k. UNDISCLOSED LIABILITIES. The Company has no material obligation or
liability (whether accrued, absolute, contingent, unliquidated, or otherwise,
whether due or to become due) arising out of transactions entered into at or
prior to the Closing of this Agreement, or any action or inaction at or prior to
the Closing of this Agreement, or any state of facts existing at or prior to the
Closing of THIS Agreement, except (a) liabilities reflected on the latest
balance sheet included in the SEC Documents (the "Company Balance Sheet"), (b)
liabilities incurred in the ordinary course of business since the date of the
Company Balance Sheet (none of which is a liability for breach of contract,
breach of warranty, torts, infringements, claims or lawsuits), and (c)
liabilities or obligations disclosed on Schedule 3.k. hereto.

     l. STABILIZATION AND MANIPULATION. Neither the Company, nor, to the
knowledge of the Company, any of its affiliates or their respective agents,
officers, directors or employees has taken or may take, directly or indirectly,
any action designed to cause or result in, or which has constituted or which
might reasonably be expected to constitute, the stabilization or manipulation of
the price of the shares of Common Stock..

     m. ABSENCE OF CERTAIN CHANGES. Except as disclosed to the Purchaser and in
the Company's public filings with the Commission, since June 30, 2002, there has
been no material adverse change nor any material adverse development in the
business, properties, operations, financial condition, prospects, outstanding
securities, employee relations, customer relations or results of operations of
the Company or its subsidiaries, taken as a whole (each, a "Material Adverse
Effect").

     n. Environmental. Except as disclosed in the SEC Documents, and except for
instances of noncompliance with or exceptions to the following that could not
have been, individually or in the aggregate, a Material Adverse Effect: (i) the
Company and its subsidiaries are in full compliance with all environmental laws;
(ii) the Company is not aware of, nor has the Company received notice of, any
past, present, or future conditions, events, activities, practices, or incidents
which may interfere with or prevent the compliance or continued compliance of

subsidiaries have good and marketable title to all of their material properties
and assets, both real and personal, and have good title to all their leasehold
interests, in each case subject only to mortgages, pledges, liens, security
interests, conditional sale agreements, encumbrances or charges (collectively,
"Liens") created in the ordinary course of business.

     p. PROPRIETARY RIGHTS. The Company and its subsidiaries have sufficient
title and ownership of all trademarks, service marks, trade names, internet
domain names, copyrights, trade secrets, information, proprietary rights and
processes necessary for the conduct of their business as now conducted and as

does not conflict with or constitute an infringement on the rights of others.

     q. PERMITS. The Company and its subsidiaries have all franchises, permits,
licenses and any similar authority necessary for the conduct of their business
as now conducted, the lack of which could result in a Material Adverse Effect.
The Company and its subsidiaries are not in default in any respect under any of
such franchises, permits, licenses or similar authority.

     r. ABSENCE OF LITIGATION. Except as disclosed in the Company's public
filings with the Commission, there is no action, suit, proceeding, inquiry or
investigation before or by



<PAGE>



any court, public board or body pending or, to the knowledge of the Company or
any of its subsidiaries, threatened against or affecting the Company or any of
its subsidiaries.

     s. NO DEFAULT. Each of the Company and its subsidiaries is not in default
in the performance or observance of any obligation, covenant or condition
contained in any indenture, mortgage, deed of trust or other instrument or
agreement to which it is a party or by which it or its property may be bound
which default could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect.

     t. TRANSACTIONS WITH AFFILIATES. Except as disclosed in the Company's
public filings with the Commission, there are no agreements, understandings or
proposed transactions between the Company or any of its subsidiaries and any of
their officers, directors or affiliates that, had they existed on June 30, 2002,
would have been required to be disclosed in the Company's Annual Report or an
amendment thereto.

     u. EMPLOYMENT MATTERS. The Company and its subsidiaries are in material
compliance with all federal, state, local and foreign laws and regulations
respecting employment and employment practices, terms and conditions of
employment and wages and hours. There are no pending investigations involving
the Company or any of its subsidiaries by any other governmental agency. There
is no strike, picketing, boycott, dispute, slowdown or stoppage pending or
threatened against or involving the Company or any of its subsidiaries. No
grievance or arbitration proceeding is pending under any expired or existing
collective bargaining agreements of the Company or any of its subsidiaries. No
material labor dispute with the employees of the Company or any of its
subsidiaries exists or, to the knowledge of the Company, is imminent.

     v. ERISA MATTERS. Except as set forth in the Company's public filings with
the Commission, neither the Company nor any ERISA Affiliate of the Company (as
defined below) maintains, administers, contributes to or is obligated to
contribute to any employee pension benefit plan (as defined in Section 3(2) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")),
including, without limitation, any multiemployer plan as defined in Section
3(37) of ERISA; employee welfare benefit plan (as defined in Section 3(1) of
ERISA); or bonus, deferred compensation, stock purchase, stock option, severance
plan, salary continuation, vacation, sick leave, fringe benefit, incentive,
insurance, welfare or similar arrangement (all of the foregoing being hereafter
referred to as a "Plan" and collectively as the "Plans") with respect to any of
its employees. The Company (i) has materially complied with all of the
provisions of each such Plan and all applicable provisions of ERISA and the
Internal Revenue Code of 1986, as amended (the "Code"), (ii) has administered
each such Plan (including the payment of benefits thereunder) in accordance with
the material provisions of each such Plan and all applicable material provisions
of ERISA and the Code, and (iii) no penalties under ERISA or any other
applicable law or regulation are owed to any Plan participant, beneficiary
and/or governmental authority with respect to the failure to file any reports or
other information required under ERISA or any other applicable law or regulation
or to distribute or make available any such reports or other information. The
Company has timely made all required contributions to each such Plan. No such
Plan is subject to Title IV of ERISA or has at any time been subject to Section
3(2) of ERISA or a "multiemployer plan" within the meaning of Section 3(37) of
ERISA or Section 4001(a)(3) of ERISA. None of the Plans is under investigation
or audit by either the United States Department of Labor or the Internal Revenue
Service. For these purposes, "ERISA Affiliate" means all members of a



<PAGE>



controlled group of corporations and all trades and businesses (whether or not
incorporated) under common control and all other entities which, together with
the Company, are treated as a single employer under any or all of Section
414(b), (c), (m) or (o) of the Code on either the date of this Agreement or the
Closing Date.

     w. INSURANCE. The Company and its subsidiaries maintain property and
casualty, general liability, personal injury and other similar types of
insurance that are reasonably adequate, consistent with industry standards and
their historical claims experience. The Company and its subsidiaries have not
received notice from, and have no knowledge of any threat by, any insurer (that
has issued any insurance policy to the Company or its subsidiaries) that such
insurer intends to deny coverage under or cancel, discontinue or not renew any
insurance policy covering the Company or any of its subsidiaries presently in
force.

     x. TAXES. All applicable tax returns required to be filed by the Company
and each of its subsidiaries have been prepared and filed in compliance with all
applicable laws and were true, correct and complete in all material respects
when filed, or if not yet filed have been granted extensions of the filing dates
which extensions have not expired, and all taxes, assessments, fees and other
governmental charges upon the Company, its subsidiaries, or upon any of their
respective properties, income or franchises, required to be paid by the Company
or its subsidiaries have been paid, or adequate reserves therefor have been set
up if any of such taxes are being contested in good faith; or if any of such tax
returns have not been filed or if any such taxes have not been paid or so
reserved for, the failure to so file or to pay would not in the aggregate have a
Material Adverse Effect. All amounts required to be withheld by the Company or
any of its subsidiaries from employees for income, social security and other
payroll taxes have been collected and withheld and have either been paid to the
appropriate agency, set aside in accounts for such purpose or accrued and
reserved upon the books and records of the Company or the appropriate
subsidiary. There were no tax liens on any of the Company's or its subsidiaries'
assets that arose in connection with the failure, or alleged failure, to pay any
taxes except for liens for taxes not yet due and payable. No taxing authority is
asserting or threatening to assert against the Company or any of its
subsidiaries any deficiency or claim for additional taxes and no tax return of
Company or any of its subsidiaries is currently under audit by any tax
authority. The provision for taxes on the Company Balance Sheet adequately
reflects all tax liabilities in accordance with U.S. generally accepted
accounting principles.

     y. FOREIGN CORRUPT PRACTICES ACT. Neither the Company, its subsidiaries nor
any of their respective directors, officers or other agents has: (i) used any
Company funds for any unlawful contribution, endorsement, gift, entertainment or
other unlawful expense relating to any political activity; (ii) made any direct
or indirect unlawful payment of company funds to any foreign or domestic
government official or employee; (iii) violated or is in violation of any
provision of the Foreign Corrupt Practices Act of 1977, as amended; or (iv) made
any bribe, rebate, payoff, influence payment, kickback or other similar payment
to any person.

     z. COMPLIANCE WITH LAW. To the best of their knowledge, the Company and its
subsidiaries have complied in all material respects with all applicable statutes
and regulations of the United States and of all states, municipalities and
applicable agencies and foreign jurisdictions or bodies in respect of the
conduct of its business and operations, and the failure, if any, by the Company
or its subsidiaries to have fully complied with any such statute or regulation
has not and will not result in a Material Adverse Effect.


<PAGE>



     aa. INTERNAL CONTROLS. The Company and its subsidiaries maintain a system
of internal accounting controls sufficient to provide reasonable assurances
that: (i) transactions are executed in accordance with management's general or
specific authorization; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with U.S. generally accepted
accounting principles and to maintain accountability for assets; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

     bb. INVESTMENT COMPANY ACT. The Company and its subsidiaries are not
conducting, and will not conduct, their business in a manner which would cause
any of them to become an "investment company," as defined in Section 3(a) of the
Investment Company Act of 1940, as amended.

     cc. BROKERAGE FEES. The Company and its subsidiaries have not incurred any
liability for any consulting fees or agent's commissions in connection with the
exchange of the Company Shares or the Warrants with the Purchaser and the
transactions contemplated by this Agreement.

     dd. PRIVATE OFFERING. Subject to the accuracy of the Purchaser's
representations and warranties set forth in Section 2 hereof, the offer, sale
and issuance of the Company Shares or the Warrants and the conversion and/or
exercise of such securities into shares of Common Stock, each as contemplated by
this Agreement, are exempt from the registration requirements of the Securities
Act. The Company agrees that neither the Company nor anyone acting on its behalf
will offer any of the Company Shares or the Warrants, or any similar securities,
for issuance or sale, or solicit any offer to acquire any of the same from
anyone so as to render the issuance and sale of such securities subject to the
registration requirements of the Securities Act. The Company has not offered or
sold the Company Shares or the Warrants by any form of general solicitation or
general advertising, as such terms are used in Rule 502(c) under the Securities
Act.

     ee. FULL DISCLOSURE. Neither this Agreement, the Primary Documents nor any
of the schedules, exhibits, written statements, documents or certificates
prepared or supplied by the Company with respect to the transactions
contemplated hereby contain any untrue statement of a material fact or omit a
material fact necessary to make the statements contained herein or therein not
misleading in light of the circumstances under which made. Except as disclosed
in the SEC Documents and except for matters affecting the industry of the
Company as a whole, there exists no fact or circumstance which, to the knowledge
of the Company upon due inquiry, could reasonably be anticipated to have a
Material Adverse Effect or could adversely affect the ability of the Company to
perform its obligations set forth in the Primary Documents.

     ff. MINUTE BOOKS. The Company's minute books, which have been previously
made available to the Purchaser, are in good order, complete, accurate,
up-to-date, and with all necessary signatures, and set forth the Company's
articles of incorporation and bylaws, as amended, and all meetings and actions
taken by the directors and stockholders.

     gg. STOCK RECORDS. The Company's transfer agent for its Common Stock is
Interwest Transfer Co., Inc. The stock transfer books and stock ledgers of the
Company are in good order, complete, accurate, up-to-date, and with all
necessary signatures, and set forth all stock and securities issued,
transferred, and surrendered, including duplicate certificates. No transfer


<PAGE>


has been made without surrender of the proper certificate of the Company, duly
endorsed, and the Company has cancelled and retained such certificates in its
stock records.

4.   CERTAIN COVENANTS AND ACKNOWLEDGMENTS

     a. TRANSFER RESTRICTIONS. The Purchaser acknowledges that, except as
provided in the Registration Rights Agreement, (i) none of the Securities have

sale of the Securities made in reliance upon Rule 144 under the Securities Act
may bE MADE ONLY IN ACCORDANCE WITH THE TERMS OF SAID RULE. THE PROVISIONS OF

such registration shall no longer be required, such Securities shall bear a
restrictive legend in substantially the following form:

     THESE SECURITIES (INCLUDING ANY UNDERLYING SECURITIES) HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE
     SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN
     THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES

required filings in connection with the exchange of the Securities with the

Regulations of the Commission), and to provide copies thereof to the Purchaser
promptly after such filing or filings.

system as soon as practicable. The Company further agrees and covenants that it
will not seek to have the trading of its Common Stock on OTCBB or Nasdaq (when
obtained) suspended or terminated, will use its best efforts to maintain its
eligibility for trading on OTCBB or Nasdaq and, if such trading of its Common
Stock is suspended or terminated, will use its best efforts to requalify its

take such action as the Purchaser may request to qualify the Securities for

continuance of sales therein.

     g. RESERVATION OF COMMON STOCK. The Company shall at all times have
authorized and reserved for the purpose of issuance a sufficient number of
shares of Common Stock to provide for the exercise of the Warrants. The Company

full of the Warrants at such time.

     h. RETURN OF WARRANTS ON EXERCISE. Upon any partial exercise by the
Purchaser of the Warrants, the Company shall issue and deliver to the Purchaser
within three (3) days of the date on which such Warrants are exercised a new
Warrant or Warrants representing the number of adjusted shares of Common Stock

     i. REPLACEMENT WARRANTS. The Warrants will be exchangeable, at the option
of the Purchaser, at any time and from time to time at the office of the
Company, for other Warrants of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Common Stock
as are purchasable under such Warrants. No service charge will be made for such
transfer or exchange.

5.   ACTIONS PRIOR TO AND FOLLOWING CLOSING

6.   TRANSFER AGENT INSTRUCTIONS AND CONVERSION MECHANICS

     a. The Company warrants that no instruction, other than the instructions
referred to in this Section 6 hereof, prior to the registration and sale under
the Securities Act of the Common Stock issuable upon exercise of the Warrants
will be given by the Company to its transfer agent and that the shares of Common
Stock issuable upon exercise of the Warrants shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement, the Registration Rights Agreement and applicable
law. Nothing in this Section 6 shall affect in any way the Purchaser's
obligations and agreement to comply with all applicable securities laws upon
resale of the Securities. If the Purchaser provides the Company with an opinion
of counsel reasonably satisfactory to the Company that registration of a resale
by the Purchaser of any of the Securities in accordance with Section 4(a) of
this Agreement is not required under the Securities Act, the Company shall
permit the transfer of the Securities and, in the case of the Common Stock,
promptly instruct the Company's transfer agent to issue one or more certificates
for Common Stock without legend in such names and in such denominations as
specified by the Purchaser.

     b. The Purchaser shall exercise the Warrants in the manner set forth in the
Warrants. Each date on which Warrants are exercisable in accordance with the
provisions thereof shall be deemed a "Conversion Date" with respect to such
exercise. For purposes of this Agreement, any exercise of the Warrants shall be
deemed to have been made immediately prior to the close of business on the
Conversion Date.

     c. In lieu of delivering physical certificates representing the Common
Stock issuable upon the exercise of the Warrants, provided the Company's
transfer agent is participating in the Depositary Trust Company ("DTC") Fast
Automated Securities Transfer program, on the written request of the Purchaser,
who shall have previously instructed the Purchaser's prime broker to confirm
such request to the Company's transfer agent, the Company shall cause its
transfer agent to electronically transmit such Common Stock to the Purchaser by
crediting the account of the Purchaser's prime broker with DTC through its
Deposit Withdrawal Agent Commission ("DWAC") system no later than three (3)
business days after the applicable Conversion Date relating to the Warrants
(each such delivery date, a "Delivery Date").

     Nothing herein shall limit the Purchaser's right to pursue actual damages
for the Company's failure to so issue and deliver Common Stock to the Purchaser.
Furthermore, in addition to any other remedies which may be available to the
Purchaser, if the Company fails for any reason to effect delivery of such Common
Stock within five (5) business days after the relevant Delivery Date, the
Purchaser will be entitled to revoke the relevant Notice of Conversion or Form
of Election to Purchase by delivering a notice to such effect to the Company,
whereupon the Company and the Purchaser shall each be restored to their
respective positions immediately prior to delivery of such Notice of Conversion
or Form of Election to Purchase. For purposes of this Section 6, "business day"
shall mean any day in which the financial markets of New York are officially
open for the conduct of business therein.

7.   CONDITIONS TO THE COMPANY'S OBLIGATION TO ISSUE THE COMPANY SHARES AND
     WARRANTS.

     The Purchaser understands that the Company's obligation to sell the Company
Shares and the Warrants on the Closing Date to the Purchaser pursuant to this
Agreement is

conditioned upon the satisfaction or waiver by the Company of each of the
following conditions:

     a. The accuracy on the Closing Date of the representations and warranties
of the Purchaser contained in this Agreement as if made on the Closing Date and
the performance by the Purchaser on or before the Closing Date of all covenants
and agreements of the Purchaser required to be performed on or before the
Closing Date.

     b. The absence or inapplicability of any and all laws, rules or regulations
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained.

     c. The Purchaser shall have executed this Agreement and the Registration
Rights Agreement and delivered the same to the Company.

     d. The Purchaser shall have paid the Consideration in accordance with
Section 1.c. above.

8.   CONDITIONS TO THE PURCHASER'S OBLIGATION TO PURCHASE THE COMPANY SHARES AND
     THE WARRANTS

     The Company understands that the Purchaser's obligation to purchase the
Company Shares and the Warrants on the Closing Date is conditioned upon the

the performance by the Company on or before the Closing Date of all covenants

of the State of Nevada, dated a recent date, to the effect that the Company is

     f. The Purchaser shall have received a certified copy of the Articles of
Incorporation and By-laws of the Company as filed with the Secretary of State of
the State of Nevada and any amendments thereto through the Closing Date.

     g. The Purchaser shall have received from the Company such other
certificates and documents as it shall reasonably request, and all proceedings
taken by the Company in connection with the Primary Documents contemplated by
this Agreement, including resolutions adopted by its Board of Directors
authorizing the actions to be taken by it contemplated by the Primary Documents.

     h. No injunction, order, investigation, claim, action or proceeding before
any court or governmental body shall be pending or threatened wherein an
unfavorable judgment, decree or order would restrain, impair or prevent the
carrying out of this Agreement or any of the transactions contemplated hereby,
declare unlawful the transactions contemplated by this Agreement or cause any
such transaction to be rescinded.

     i. The Company shall have obtained in writing or made all consents,
waivers, approvals, orders, permits, licenses and authorizations of, any
registrations, declarations, notices to and filings and applications with, any
governmental authority or any other person or entity (including, without
limitation, security holders and creditors of the Company) required to be
obtained or made in order to enable the Company to observe and comply with all
its obligations under this Agreement and to consummate the transactions
contemplated hereby.

     j. The Company shall have performed all acts described in Section 5 hereof.


9.   INDEMNIFICATION

         A. Indemnification of Purchaser by the Company.

         The Company hereby agrees to indemnify and hold harmless the Purchaser,
its affiliates and their respective officers, directors, partners, shareholders,
employees and members (collectively, the "Purchaser Indemnitees"), from and
against any and all losses, claims, damages, judgments, penalties, liabilities
and deficiencies (collectively, "Losses"), and agrees to reimburse the Purchaser
Indemnitees for all out-of-pocket expenses (including the fees and expenses of
legal counsel), in each case promptly as incurred by the Purchaser Indemnitees
and to the extent arising out of or in connection with:

         1. any misrepresentation, omission of fact or breach of any of the
Company's representations, warranties or covenants contained in this Agreement,
the annexes, schedules or exhibits hereto or any instrument, agreement or
certificate entered into or delivered by the Company pursuant to this Agreement;
or

         2. any failure by the Company to perform any of its covenants,
agreements, undertakings or obligations set forth in this Agreement, the
annexes, schedules or exhibits hereto or any instrument, agreement or
certificate entered into or delivered by the Company pursuant to this Agreement.



<PAGE>


         B. Indemnification of the Company by the Purchaser.

         The Purchaser hereby agrees to indemnify and hold harmless the Company,
its affiliates and their respective officers, directors, partners and members
(collectively, the "Company Indemnitees"), from and against any and all Losses,
and agrees to reimburse the Company Indemnitees for all out-of-pocket expenses
(including the fees and expenses of legal counsel), to the extent arising out of
or in connection with any failure by the Purchaser to perform any of its
covenants, agreements, undertakings or obligations set forth in this Agreement,
the annexes, schedules or exhibits hereto or any instrument, agreement or
certificate entered into or delivered by the Purchaser pursuant to this
Agreement.

         C. Third Party Claims.

         Promptly after receipt by either party hereto seeking indemnification
pursuant to this Section 9 (an "Indemnified Party") of written notice of any
investigation, claim, proceeding or other action in respect of which
indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party against whom indemnification pursuant to this
Section 9 is being sought (the "Indemnifying Party") of the commencement
thereof; but the omission to so notify the Indemnifying Party shall not relieve
it from any liability that it otherwise may have to the Indemnified Party,
except to the extent that the Indemnifying Party is materially prejudiced and
forfeits substantive rights and defenses by reason of such failure. In
connection with any Claim as to which both the Indemnifying Party and the
Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ separate legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs
and expenses of such separate legal counsel to the Indemnified Party if (and
only if): (x) the Indemnifying Party shall have agreed to pay such fees,
out-of-pocket costs and expenses, (y) the Indemnified Party and the Indemnifying
Party reasonably shall have concluded that representation of the Indemnified
Party by the Indemnifying Party by the same legal counsel would not be
appropriate due to actual or, as reasonably determined by legal counsel to the
Indemnified Party, potentially differing interests between such parties in the
conduct of the defense of such Claim, or if there may be legal defenses
available to the Indemnified Party that are in addition to or disparate from
those available to the Indemnifying Party, or (z) the Indemnifying Party shall
have failed to employ legal counsel reasonably satisfactory to the Indemnified
Party within a reasonable period of time after notice of the commencement of
such Claim. If the Indemnified Party employs separate legal counsel in
circumstances other than as described in clauses (x), (y) or (z) above, the
fees, costs and expenses of such legal counsel shall be borne exclusively by the
Indemnified Party. Except as provided above, the Indemnifying Party shall not,
in connection with any Claim in the same jurisdiction, be liable for the fees
and expenses of more than one firm of legal counsel for the Indemnified Party
(together with appropriate local counsel). The Indemnifying Party shall not,
without the prior written consent of the Indemnified Party (which consent shall
not unreasonably be withheld) settle or compromise any Claim or consent to the
entry of any judgment that does not include an unconditional release of the
Indemnified Party from all liabilities with respect to such Claim or judgment.

         D. Right to Indemnification Not Affected by Knowledge.



<PAGE>


         The right to indemnification, payment for Losses or other remedy based
on any representation, warranty, covenant or obligation of a party hereunder
shall not be affected by any investigation conducted with respect to, or any
knowledge acquired (or capable of being acquired) at any time, whether before or
after the execution and delivery of this Agreement or the Closing Date, with
respect to the accuracy or inaccuracy of or compliance with, any such
representation, warranty, covenant or obligation.

10.      EXPENSES

         The Company covenants and agrees with the Purchaser that the Company
shall pay or cause to be paid the following: (i) the fees, disbursements and
expenses of the Purchaser's counsel in connection with the issuance of the
Securities (not to exceed US$6,000), payable on the Closing Date; (ii) all
expenses in connection with registration or qualification of the Securities for
offering and sale under state securities laws as provided in Section 4.f.
hereof; and (iii) all other costs and expenses incident to the performance of
its obligations hereunder which are not otherwise specifically provided for in
this Section 10, including the fees and disbursements of the Company's counsel,
accountants and other professional advisors, if any.

11.      SURVIVAL


         The agreements, covenants, representations and warranties of the
Company and the Purchaser shall survive the execution and delivery of this
Agreement and the delivery of the Securities hereunder until all of the Warrants
are exercised in full and the Company has satisfied in full its obligations
under the terms of the Registration Rights Agreement.

12.      MISCELLANEOUS

     a. GOVERNING LAW. This Agreement shall be governed by and interpreted in
accordance with the internal laws of the State of California.

     b. ARBITRATION. If a dispute arises out of or is related to this Agreement,
or the breach thereof, and such dispute cannot be settled through negotiation,
the dispute may be submitted to final and binding arbitration under the then
current rules of the Hong Kong International Arbitration Centre in Hong Kong,
China. The prevailing party in such arbitration shall be entitled to expenses,
including costs and reasonable attorneys' and other professional fees, incurred
in connection with the arbitration (but excluding any costs and fees associated
with any prior negotiation or mediation). The decision of the arbitrator shall
be final and non-appealable and may be enforced in any court of competent
jurisdiction. The use of any alternative dispute resolution procedures will not
be construed under the doctrine of laches, waiver or estoppel to adversely
affect the rights of the parties.

     c. COUNTERPARTS. This Agreement may be signed in two or more counterparts,
each of which shall be deemed an original.

     d. HEADINGS. The headings of this Agreement are for convenience of
reference only and shall not form part of, or affect the interpretation of, this
Agreement.

     e. INTERPRETATION. This Agreement and each of the Primary Documents have
been entered into freely by each of the parties, following consultation with
their respective counsel, and shall be interpreted fairly in accordance with its
respective terms, without any construction in favor of or against either party.



<PAGE>




     f. SEVERABILITY. If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement or the
validity or unenforceability of this Agreement in any other jurisdiction.

     g. SUCCESSORS. This Agreement shall inure to the benefit of, and be binding
upon the successors and assigns of each of the parties hereto, including any
transferees of the Company Shares and the Warrants.

     h. AMENDMENTS. This Agreement may be amended only by an instrument in
writing signed by the party to be charged with enforcement.

     i. MERGER. This Agreement, together with the other Primary Documents,
supersedes all prior agreements and understandings among the parties hereto with
respect to the subject matter hereof.

     j. EQUITABLE RELIEF. The Company and the Purchaser each recognize that if
any party fails to perform, observe, or discharge any or all of its obligations
under any PRIMARY Document, any remedy at law may prove to be inadequate relief
to the aggrieved party. The Company and the Purchaser therefore agree that an
aggrieved party under any Primary Document, if such party so requests, shall be
entitled to temporary and permanent injunctive relief in any such case without
the necessity of proving actual damages.

     k. NOTICES. Any notice required or permitted hereunder shall be given in
writing (unless otherwise specified herein) and shall be effective upon personal
delivery, via facsimile (upon receipt of confirmation of error-free
transmission) or two business days following deposit of such notice with an
internationally recognized courier service, with postage prepaid and addressed
to each of the other parties thereunto entitled at the following addresses, or
at such other addresses as a party may designate by five days advance written
notice to each of the other parties hereto.
