 -------                                ---------

          WHEREAS, subject to the terms and conditions set forth in this
Agreement, the Company desires to sell to the Purchaser and the Purchaser
desires to purchase from the Company certain shares (the "Initial Shares") of

Initial Closing: (A) the Company shall deliver to the Purchaser: (1) a stock
certificate representing a number of Initial Shares equal to the quotient
obtained by dividing: (x) 7,500,000 by (y) 80% of the average of the ten closing
bid prices of the Common Stock on the OTC Bulletin Board  (as reported by
Bloomberg L.P. at 4:15 PM (New York time for the closing bid price for regular
session trading on such day)) during the consecutive ten Trading Days (as
defined below) immediately preceding the Initial Closing Date (the "Initial
                                                                    -------
Purchase Price"), registered in the name of the Purchaser and free of all
--------------
restrictive legends, (2) a Common Stock purchase warrant, in the form of Exhibit
                                                                         -------
A, dated as of the Initial Closing Date and registered in the name of the
-
Purchaser, pursuant to which the Purchaser shall have the right to acquire a
number of shares of Common Stock equal to 10% of the Initial Shares, upon the
terms and conditions set forth therein (the "Initial Warrant") and (3) a file
                                             ---------------
copy of the Initial Supplement (as defined below) which shall be delivered no
later than the Trading Day immediately following the Initial Closing Date; and
(B) the Purchaser shall deliver $7,500,000 less the fees contemplated in Section

<PAGE>

obligations to acquire and pay for the Initial Shares, that the Company file
with the Securities and Exchange Commission (the "Commission") a supplement to
the Registration Statement (as defined herein) in order to evidence the offer
and sale of the Initial Shares, Initial Reset Shares (as defined herein) and
shares of Common Stock issuable upon exercise of the Initial Warrant pursuant to
the terms hereunder and under the Registration Statement (the "Initial
Supplement"). "Trading Day" means: (a) a day on which the Common Stock is
traded, listed or quoted, as the case may be, on any of the Nasdaq SmallCap
Market, New York Stock Exchange, American Stock Exchange or Nasdaq National
Market, or (b) if the Common Stock is not listed on any of the Nasdaq SmallCap
Market, New York Stock Exchange, American Stock Exchange or Nasdaq National

market, as reported by the OTC Bulletin Board, or (c) if the Common Stock is not
quoted on the OTC Bulletin Board, a day on which the Common Stock is quoted in
the over-the-counter market as reported by the National Quotation Bureau
Incorporated (or any similar organization or agency succeeding its functions of

                   --------

mean any business day.

          (b)  Subject to the terms and conditions set forth in this Agreement,
the Company shall have the right to deliver a written notice to the Purchaser (a
"Subsequent Financing Notice") requiring the Purchaser to purchase, the
 ---------------------------
Additional Shares for an aggregate purchase price of up to $7,500,000 (the
"Additional Purchase Price").  A Subsequent Financing Notice may be delivered no
 -------------------------
earlier than 195 Trading Days following the Initial Closing Date and no later
than 225 Trading Days following the Initial Closing Date, or as otherwise agreed
to by the parties.  The closing of the purchase and sale of the Additional
Shares (the "Additional Closing" and together with the Initial Closing, a
             ------------------
"Closing") shall take place at the offices of Robinson Silverman on the fifth
--------
(5/th/) business day after the Subsequent Financing Notice is deemed delivered
hereunder or on such other date as otherwise agreed to by the parties; provided,
                                                                       --------
that in no case shall the Additional Closing take place unless and until all of
the conditions listed in Section 5 have been satisfied by the Company or waived
by the Purchaser.  The date of the Additional Closing is hereinafter referred to
as the "Additional Closing Date."   Notwithstanding anything herein to the
        -----------------------
contrary, if the product of: (x) the average of the daily trading volume of the
Common Stock on the OTC Bulletin Board for the twenty consecutive Trading Days
immediately preceding the Additional Closing Date and (y) the average of the
volume weighted average price of the Common Stock on the OTC Bulletin Board (as
reported by Bloomberg L.P. at 4:15 PM (New York time) for regular session
trading on such day) for the twenty consecutive Trading Days immediately
preceding the Additional Closing Date (such product, the "Average Price") shall
                                                          -------------
be equal to or less than $200,000, then the Additional Purchase Price shall
equal the product of: (x) the quotient obtained by dividing the Average Price by
200,000 and (y) 7,500,000.

          (c)  At the Additional Closing, if any: (A) the Company shall deliver
to the Purchaser: (1) a stock certificate representing a number of Additional
Shares equal to the quotient obtained by dividing: (x) the Additional Purchase
Price by (y) 80% of the average of the ten closing bid prices of the Common
Stock on the OTC Bulletin Board  (as reported by Bloomberg L.P. at 4:15 PM (New
York time for the closing bid price for regular session trading on such day))
during the ten Trading
<PAGE>

Days immediately preceding the Additional Closing Date (the "Additional Purchase

Price"), registered in the name of the Purchaser and free of all restrictive
legends, (2) a Common Stock purchase warrant, in the form of Exhibit A, dated as
                                                             ---------
of the Additional Closing Date and registered in the name of the Purchaser,
pursuant to which the Purchaser shall have the right to acquire a number of
shares of Common Stock equal to 10% of the Additional Shares, upon the terms and
conditions set forth therein (the "Additional Warrant" and together with the
                                   ------------------
Initial Warrant, the "Warrants") and (3) a prospectus supplement to the
Registration Statement disclosing the sale of the Additional Shares, Additional
Reset Shares (as defined herein) and shares of Common Stock issuable upon
exercise of the Additional Warrant pursuant to the terms hereunder and under the
Registration Statement (the "Additional Supplement") which shall be delivered on
                             ---------------------
the Trading Day immediately following the Additional Closing Date; and (B) the
Purchaser shall deliver the Additional Purchase Price less $2,500 to be paid to
Robinson Silverman in payment of the Purchaser's legal fees in connection with
the Additional Closing, in immediately available funds by wire transfer to an
account designated in writing by the Company for such purpose. It shall be a
condition precedent to the Purchaser's obligations to acquire and pay for the
Additional Shares that the Company file with the Commission the Additional
Supplement.

          2.   Representations and Warranties of the Company.  The Company
               ---------------------------------------------
hereby makes the following representations and warranties to the Purchaser as of
the date hereof:

          (a)  Organization and Qualification.  The Company is a corporation
               ------------------------------
duly incorporated, validly existing and in good standing under the laws of the
State of Nevada with the requisite corporate power and authority to own and use
its properties and assets and to carry on its business as currently conducted.

          (b)  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 and the Warrants by the Company and the
consummation by it of the transactions contemplated thereby have been duly
authorized by all necessary action on the part of the Company and no further
action is required by the Company other than the filings with the Commission of
the prospectus supplements described herein.  This Agreement has been duly
executed by the Company and, assuming the valid execution thereof by the
Purchaser, when delivered in accordance with the terms hereof, will constitute
the valid and binding obligation of the Company enforceable against the Company
in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting creditors' and contracting parties' rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability in a proceeding in equity or at law).

          (c)  Capitalization.  The authorized, issued and outstanding capital
               --------------
stock of the Company is set forth in Schedule 2.1(c). Except as disclosed in
                                     ---------------
Schedule 2.1(c), the Company owns all of the capital stock of each of its
subsidiaries. No shares of Common Stock are entitled to preemptive or similar
rights, nor is any holder of the securities of the Company or any subsidiary
<PAGE>

of the Company entitled to preemptive or similar rights arising out of any
agreement or understanding with the Company or any subsidiary by virtue of the
transactions contemplated by this Agreement. Except as contemplated by this
Agreement or as disclosed in Schedule 2.1(c), there are no outstanding options,
warrants, script rights to subscribe to, calls or commitments of any character
whatsoever relating to, or securities, rights or obligations convertible into or
exchangeable for, or giving any person any right to subscribe for or acquire,
any shares of Common Stock, or contracts, commitments, understandings, or
arrangements by which the Company or any subsidiary of the Company is or may
become bound to issue additional shares of Common Stock, or securities or rights
convertible or exchangeable into shares of Common Stock. Except as disclosed in
Schedule 2.1(c), the issue and sale of the Securities (as hereinafter defined)
pursuant to the terms hereof will not obligate the Company to issue shares of
Common Stock or other securities to any person other than the Purchaser and will
not result in a right of any holder of Company securities to adjust the exercise
or conversion or reset price under any securities of the Company held by such
holders.

          (d)  No Conflicts.  The execution, delivery and performance of this
               ------------
Agreement and the Warrants 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 or articles of incorporation,
bylaws or other charter documents (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, acceleration or cancellation (with or without
notice, lapse of time or both) of, any agreement, credit facility, debt or other
instrument or other understanding 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, injunction,
decree or other restriction of any court or governmental authority to which the
Company is subject (including federal and state securities laws and
regulations).

          (e)  Issuance of the Shares.  The Company has on the date hereof (and
               ----------------------
will, at all times while the Warrants are outstanding, maintain) an adequate
reserve of duly authorized shares of Common Stock, reserved for issuance to the
Purchaser, to enable the Company to perform the exercise and other obligations
under this Agreement and the Warrants.   Such number of  reserved and available
shares of Common Stock shall not be less than 4,984,774.  The shares of Common
Stock issuable upon exercise of the Warrants are collectively referred to herein
as the "Underlying Shares." The Shares, Reset Shares (as defined herein),
        -----------------
Warrants and the Underlying Shares are collectively referred to herein as, the
"Securities."  When issued in accordance with the Warrants, the Underlying
-----------
Shares will be duly authorized, validly issued, fully paid and nonassessable,
free and clear of all liens, encumbrances and rights of first refusal of any
kind.

          (f)  Registration Statement.  The Company's Registration Statement on
               ----------------------
Form S-3 (Commission File No. 333-35358) (the "Registration Statement") was
                                               ----------------------
declared effective by the Commission on May 25, 2000 and the Company has not
received notice that the Commission has issued or intends to issue a stop order
with respect to the Registration Statement or that the Commission otherwise has
suspended or withdrawn the effectiveness of the Registration Statement,
<PAGE>

either temporarily or permanently, or intends or has threatened in writing to do
so. The Registration Statement (including the information or documents
incorporated by reference therein), as of the time it was declared effective,
and any amendments or supplements thereto, each as of the time of filing, did
not contain any untrue statement of material fact or omit to state any material
fact required to be state therein or necessary to make the statements therein
not misleading. The issuance of the Shares, Reset Shares (if applicable) and
Underlying Shares to the Purchaser is covered by the Registration Statement.
$30,000,000 of shares of Common Stock (including shares of Common Stock issuable
upon exercise of warrants) remain unused and unreserved under the Registration
Statement.

          (g)  SEC Documents; Financial Statements. The Company has filed all
               -----------------------------------
reports required to be filed by it under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), including, without limitation, all filings
              ------------
required pursuant to Sections 13(a) and 15(d) thereof, for the two years
preceding the date hereof (or such shorter period as the Company was required by
law to file such material) (the foregoing materials being collectively referred
to herein as the "SEC Documents") on a timely basis or has received a valid
                  -------------
extension of such time of filing and has filed any such SEC Documents prior to
the expiration of any such extension.  As of their respective dates, the SEC
Documents complied in all material respects with the requirements of the
Securities Act of 1933, as amended (the "Securities Act") and the Exchange Act
                                         --------------
and the rules and regulations of the Commission promulgated thereunder, and none
of the SEC Documents, when filed, contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or

otherwise specified in such financial statements or the notes thereto, and
fairly present in all material respects the financial position of the Company
and its consolidated subsidiaries as of and for the dates thereof and the
results of operations and cash flows for the periods then ended, subject, in the
case of unaudited statements, to normal, immaterial, year-end audit adjustments.
Since June 30, 2000, except as specifically disclosed in the SEC Documents: (a)

person acting on its behalf has provided the  Purchaser or its agents or counsel
with any information that constitutes or might constitute material non-public
information.  The Company understands and confirms that the Purchaser shall be
relying on the foregoing representations in effecting transactions in securities

its business and the transactions contemplated hereby are true and correct and

such Purchaser enforceable in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' and contracting
parties' rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

          (b)  No Conflicts.  The execution, delivery and performance of this

is subject (including federal and state securities laws and regulations).

             ------------------------------------

          (a)  Issuance of additional shares of Common Stock.  (i) On each of
               ---------------------------------------------
the 65/th/, 130/th/ and 195/th/ Trading Day following the Initial Closing Date
(each of such three dates, an "Initial Reset Date"), the Company shall issue to
                               ------------------
the Purchaser a stock certificate, registered in the name of the Purchaser and
free of all restrictive legends, representing a number of shares of Common Stock
(the "Initial Reset Shares") calculated in accordance with the following
      --------------------
formula:

 (1/3 of the Initial Shares) x [(Initial Purchase Price)(Initial Percentage) -
 -----------------------------------------------------------------------------
                          Initial Adjustment Price)]
                           --------------------------
                            Initial Adjustment Price

     "Initial Percentage" shall mean: (i) for the first Initial Reset Date,
     115%, (ii) for the second Initial Reset Date, 125% and (iii) for the third
     Initial Reset Date, 140%.

     "Initial Adjustment Price" shall mean the average of the twenty two lowest
     closing bid prices of the Common Stock on the OTC Bulletin Board (as
     reported by Bloomberg L.P. at 4:15 PM (New York time for the closing bid
     price for regular session trading on such day)) during the 65 Trading Days
     immediately preceding the applicable Initial Reset Date, provided that such
     65 Trading Day period shall, at the option of the Purchaser, be extended
     for the number of Trading Days during such period in which the Registration
     Statement ceases to register or remain effective as to all Shares, Reset
     Shares and Underlying Shares.

     If the number calculated in accordance with the foregoing formula is zero
or a negative number, no Initial Reset Shares shall be issuable by the Company
hereunder and the Purchaser shall not be obligated to transfer any shares of
Common Stock to the Company.

          (ii) On each of the 65/th/, 130/th/ and 195/th/ trading day following
the Additional Closing Date, if any (each of such three dates, a "Additional
                                                                  ----------
Reset Date"), the Company shall issue to the Purchaser a stock certificate,
----------
registered in the name of the Purchaser and free of all restrictive legends,
representing a number of shares of Common Stock (the "Additional Reset Shares"
                                                      -----------------------
and together with the Initial Reset Shares, the "Reset Shares") calculated in
                                                 ------------
accordance with the following formula:

    (1/3 of the Additional Shares) x [(Additional Purchase Price)(Additional
    ------------------------------------------------------------------------
                  Percentage) - Additional Adjustment Price)]
                  -------------------------------------------
                          Additional Adjustment Price
<PAGE>

     "Additional Percentage" shall mean: (i) for the first Additional Reset
     Date, 115%, (ii) for the second Additional Reset Date, 125% and (iii) for
     the third Additional Reset Date, 140%.

     "Additional Adjustment Price" shall mean the average of the twenty two
     lowest closing bid prices of the Common Stock on the OTC Bulletin Board (as
     reported by Bloomberg L.P. at 4:15 PM (New York time for the closing bid
     price for regular session trading on such day)) during the 65 Trading Days
     immediately preceding the applicable Additional Reset Date, provided that
     such 65 Trading Day period shall, at the option of the Purchaser, be
     extended for the number of Trading Days during such period in which the
     Registration Statement ceases to register or remain effective as to all
     Shares, Reset Shares and Underlying Shares.

     If the number calculated in accordance with the foregoing formula is zero
or a negative number, no Additional Reset Shares shall be issuable by the
Company hereunder and the Purchaser shall not be obligated to transfer any
shares of Common Stock to the Company.

     (b)  Subsequent Financing.  From the date hereof through the first year
          --------------------
anniversary of the last Closing Date to occur, the Company will not offer, sell,
grant any option to purchase, or otherwise dispose of (or announce any offer,
sale, grant or any option to purchase or other disposition) any of its equity or
equity equivalent securities (including the issuance of any debt or other
instrument at any time over the life thereof convertible into or exchangeable
for Common Stock) at a price which is less than the average of the ten closing
bid prices of the Common Stock on the OTC Bulletin Board  (as reported by
Bloomberg L.P. at 4:15 PM (New York time for the closing bid price for regular
session trading on such day)) during the ten Trading Days (as defined below)
immediately preceding the issuance date thereof.  The restrictions contained in
this paragraph shall not apply to the granting of options to employees, officers
or directors of the Company, and the issuance of Common Stock upon exercise of
such options granted under any stock option plan heretofore or hereinafter duly
adopted by the Company.

     (c)  Registration.  On each Initial Reset Date and each Additional Reset
          ------------
Date on which the Company shall issue Reset Shares pursuant to the terms hereof,
the Company shall file a supplement to the Registration Statement in order to
evidence the issuance of such Reset Shares. If, while the Purchaser holds
Securities, the Registration Statement ceases to register or remain effective as
to 115% of the Shares, Reset Shares and Underlying Shares, (assuming the Warrant
then held by the Purchaser is fully exercised on such date) then held by the
Purchaser (such securities, the "Registrable Securities"), then the Company
shall as soon as possible, but in any event within 15 business days of such
event, prepare and file with the Commission such amendments or supplements to
the Registration Statement, or such additional registration statements (as the
case may be), as may be required to register such Registrable Securities.

     (d)  Liquidated Damages.  If, while  the Purchaser holds Securities, the
          ------------------
Registration Statement ceases to be effective as to all Securities to which it
is required to relate for a period in excess of ten Trading Days then, on such
tenth Trading Day and each tenth Trading Day thereafter until the Registration
Statement becomes effective as to all Securities to which it is required to
relate, the Company shall pay to the Purchaser an amount in cash, as liquidated
damages and not as penalty, equal to 3.0% of the closing bid price of the Shares
and Reset Shares then held by the Purchaser. If the Company fails to pay any
liquidated damages pursuant to this Section in full within seven days after the
date payable, the Company will pay interest thereon at a rate of 15% per annum
(or such lesser maximum amount that is permitted to be paid by applicable law) ,
accruing daily from the date
<PAGE>

such liquidated damages become due until such amounts, plus all such interest
thereon, are paid in full. The liquidated damages pursuant to the terms hereof
shall apply on a pro-rata basis for any portion of a ten-day period prior to a
cure hereunder.

     5.   Conditions precedent to the Additional Closing. Notwithstanding
