                           securities, and Purchaser is not participating,

violations which either singly or in the aggregate do not and will not have a
Material Adverse Effect. The Company is not required under federal, state or
local law, rule or regulation to obtain any consent, authorization or order of,
or make any filing or registration with, any court or governmental agency in
order for it to execute, deliver or perform any of its obligations under this

PROVIDED that, for purposes of the representation made in this sentence, the
Company is assuming and relying upon the accuracy of the relevant
representations and agreements of Purchaser herein. The Company is not in
violation of any material term of or in material default under its Articles of
Incorporation, of any outstanding series of preferred stock or Bylaws or their

order or any statute, rule or regulation applicable to the Company, which has
not been duly waived as of the date of this Agreement.

                  4.9 SEC DOCUMENTS. The Company has not provided to Purchaser
any information which according to applicable law, rule or regulation, should
have been disclosed publicly prior to the date hereof by the Company but which
has not been so disclosed. As of their respective dates, the SEC Documents
complied, and all similar documents filed with the SEC prior to the Closing Date
will comply, in all material respects with the requirements of the Securities
Act or the Exchange Act, as the case may be, and rules and regulations of the
SEC promulgated thereunder and other federal, state and local laws, rules and
regulations applicable to such SEC Documents, and none of the SEC Documents
contained, nor will any similar document filed with the SEC prior to the Closing
Date contain, 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, as of the dates thereof, complied, and all similar documents filed
with the SEC prior to the Closing Date will comply, as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC and other applicable rules and regulations with respect
thereto. Such financial statements were prepared in accordance with generally
accepted accounting principles applied on a consistent basis 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
as permitted by Form 10-Q of the SEC) and fairly present in all material
respects the financial position of the Company as of 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 year-end audit adjustments).

                  4.10 NO UNDISCLOSED LIABILITIES. Except as set forth in
Schedule 4.10, the Company has no liabilities or obligations of a financial
nature (whether accrued, absolute, contingent or otherwise), which are material,
individually or in the aggregate, and are not disclosed in the SEC Documents,
other than those incurred in the ordinary course of the Company's business
consistent with past practice since September 30, 1999, and which, individually
or in the aggregate, do not or would not have a Material Adverse Effect on the
Company.

                  4.11 LITIGATION AND OTHER PROCEEDINGS. Except as may be set
forth in the SEC Documents or set forth in Schedule 4.11, there are no lawsuits
or proceedings pending or, to the best knowledge of the Company, threatened,
against the Company, nor has the Company received any written or oral notice of
any such action, suit, proceeding or investigation, which might have a Material
Adverse Effect on the Company or which likely would have a Material Adverse
Effect on the transactions contemplated by this Agreement. Except as set forth
in the SEC Documents, no judgment, order, writ, injunction or decree or award
has been issued by or, to the best knowledge of the Company, requested of any
court, arbitrator or governmental agency which likely would have a Material
Adverse Effect on the transactions contemplated by this Agreement.

                  4.12 OTHER DOCUMENTS OR MATERIALS. With respect to any
document or other materials received by Purchaser from the Company or its
representatives other than the Transaction Documents and the SEC Documents, (i)
the Company has no reason to believe any of such documents and materials or any
projections contained therein, as of the date of such other documents or
materials, contained errors or misstatements or do not adequately describe the
status of the development of the Company's technologies or its business as of
such date, and (ii) such documents, materials and projections were prepared by
the Company and its management in good faith.

                  4.13 NATURE OF COMPANY. The Company is not an open-ended
investment company or a unit investment trust, registered or required to be
registered, or a closed end investment company required to be registered, but
not registered, under the Investment Company Act of 1940.

                  4.14 BROKERS, FINDERS. Except for the payment of consulting
fees to Spinneret Financial Systems, Inc., payment of which is the sole
responsibility of the Company, the Company has taken no action which would give
rise to any claim by any person for brokerage commission, finder's fees or
similar payments by Purchaser relating to this Agreement or the transactions
contemplated hereby. Purchaser shall have no obligation with respect to such
fees or with respect to any claims made by or on behalf of other persons for
fees of a type contemplated in this Section 4.14 that may be due in connection
with the transactions contemplated hereby. The Company shall indemnify and hold
harmless each of Purchaser and its employees, officers, directors, agents,
partners and affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses suffered
in respect of any such claimed or existing fees, as and when incurred.

                  4.15 ABSENCE OF CERTAIN CHANGES. Except as set forth in
Schedule 4.15, since December 31, 2000, no Material Adverse Effect has been
suffered by, and no material adverse development has occurred in the business,
properties, operations, financial condition or results of operations of the
Company. The Company has not taken any steps, and does not currently expect to
take any steps, to seek protection pursuant to any bankruptcy law, nor does the
Company have any knowledge or reason to believe that its creditors intend to
initiate involuntary bankruptcy proceedings.

                  4.16 INTELLECTUAL PROPERTY RIGHTS. To its knowledge without
conducting any special investigation and except as set forth on Schedule 4.16,
the Company owns or possesses adequate rights or licenses to use all trademarks,
trade names, service marks, service mark registrations, service names, patents,
patent rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct its businesses as
now conducted. None of the Company's trademarks, trade names, service marks,
service mark registrations, service names, patents, patent rights, copyrights,
inventions, licenses, approvals, government authorizations, trade secrets or
other intellectual property rights has expired or terminated, or is expected to
expire or terminate in the near future. Except as set forth on Schedule 4.16,
the Company does not have any knowledge of any infringement by the Company of
trademarks, trade name rights, patents, patent rights, copyrights, inventions,
licenses, service names, service marks, service mark registrations, trade
secrets or other similar rights of others, or of any such development of similar
or identical trade secrets or technical information by others and, there is no
claim, action or proceeding being made or brought against, or to the best
knowledge of the Company, being threatened against, the Company regarding
trademark, trade name, patent, patent rights, invention, copyright, license,
service name, service mark, service mark registration, trade secret or other
infringement; and the Company is unaware of any facts or circumstances which
might give rise to any of the foregoing. The Company has taken reasonable
security measures to protect the secrecy, confidentiality and value of all of
their intellectual properties.

                  4.17 INTERNAL ACCOUNTING CONTROLS. The Company is not aware
that its system of internal accounting controls is not sufficient to provide
reasonable assurance that (i) transactions are executed in accordance with
management's general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles and to maintain asset accountability,
(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 the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

                  4.18 TAX STATUS. Except as set forth in Schedule 4.18, the
Company has made or filed all federal and state income and all other tax
returns, reports and declarations required by any jurisdiction to which it is
subject and has paid all taxes and other governmental assessments and charges
that are material in amount, shown or determined to be due on such returns,
reports, declarations, except those being contested in good faith and has set
aside on its books provisions reasonably adequate for the payment of all taxes
for periods subsequent to the periods to which such returns, reports, or
declarations apply. There are no unpaid taxes in any material amount claimed to
be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

                  4.19 CERTAIN TRANSACTIONS. Except as set forth in the SEC
Documents and except for arm's length transactions pursuant to which the Company
makes payments in the ordinary course of business upon terms no less favorable
than the Company could obtain from third parties and other than the grant of
stock options, none of the officers, directors or employees of the Company (or
any spouse or relative of any such person) is presently a party to any
transaction with the Company (other than for services as employees, officers and
directors), including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

                  4.20 DILUTION. The number of shares of Common Stock issuable
as Repriced Shares may increase substantially in certain circumstances,
including, but not necessarily limited to, the circumstance wherein the trading
price of the Common Stock declines during the period between the Effective Date
and the end of the Final Repricing Period. The Company's executive officers and
directors have studied and fully understand the nature of the transactions
contemplated by this Agreement and recognize that they have a potential dilutive
effect. The board of directors of the Company has concluded, in its good faith
business judgment, that such issuance is in the best interests of the Company.
The Company specifically acknowledges that its obligation to issue the Repriced
Shares is binding upon the Company and enforceable regardless of the dilution
such issuance may have on the ownership interests of other shareholders of the
Company.

                                       15
<PAGE>

                  4.21 MARKET QUOTES. The Company's Common Stock is presently
quoted on the American Stock exchange under the symbol "EUO". Except as set
forth on Schedule 4.21, the Company is not in receipt of any written notice from
any stock exchange, market or trading facility on which the Common Stock is or
has been listed or traded (or on which it is or has been quoted) to the effect
that the Company is not in compliance with the listing or maintenance
requirements of such stock exchange, market or trading facility or that the
Common Stock will be delisted from such stock exchange, market or trading
facility.

                  4.22 a. Offshore Transaction. Company has not offered these
securities to any person in the United States or to any U.S. person as that term
is defined in Regulation S.

                  b. In regard to this transaction, Company has not conducted
any "direct selling efforts" as that term is defined in Rule 902 of regulation S
nor has Company conducted any general solicitation relating to the offer and
sale of the within securities to persons resident within the United States or
elsewhere.

                  4.23 NO INTEGRATED OFFERING. Neither the Company nor any of
its affiliates nor any person acting on its or their behalf has, directly or
indirectly, at any time since June 1, 1999, made any offer or sales of any
security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under
Regulation D in connection with the offer and sale of the Shares as contemplated
hereby.

         5. USE OF PROCEEDS. The Company will use the proceeds received
hereunder (excluding amounts paid by the Company for legal fees, finder's fees
and escrow fees in connection with the sale of the Common Stock) for the purpose
of woking capital and the Company shall not vary such purpose or amount without
the prior written consent of the Investor in each instance. Unless specifically
consented to in advance in each instance by the Investor, the Company shall not,
directly or indirectly, use such proceeds for the repayment of any outstanding
loan by the Company to any other party.

         6. COMPANY RELIANCE ON PURCHASER'S REPRESENTATIONS. Purchaser
understands that the Company is relying on the truth and accuracy of the
representations and warranties made herein by Purchaser in offering the Shares
for sale and in relying upon applicable exemptions available under the Act and
applicable state securities laws.

                                       16
<PAGE>

         7. RESTRICTED SHARES. Purchaser understands and acknowledges that the
Shares have not been, and will not as of the time issued, be registered under
the Securities Act and that they will be issued in reliance upon exemptions from
the registration requirements of the Securities Act, and thus cannot be resold
unless they are included in an effective registration statement filed under the
Securities Act or unless an exemption from registration is available for such
resale. With regard to the restrictions on resales of the Shares for which a
Registration Statement is not effective, Purchaser is aware: (a) that the
Company will issue stop transfer orders to its stock transfer agent in the event
of attempts to improperly transfer any such Shares, and (b) that a restrictive
legend will be placed on certificates representing the Shares, which legend will
read substantially as follows:

         THESE SECURITIES (THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE
         AND MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT FOR THE SECURITIES OR AN OPINION OF COUNSEL OR
         OTHER EVIDENCE ACCEPTABLE TO THE CORPORATION THAT SUCH REGISTRATION IS
         NOT REQUIRED.

The legend set forth above shall be promptly removed, and the Company shall
issue a certificate without such legend to the holder of any such Unlegended
Shares (as defined below) upon which such legend is stamped, if, unless
otherwise required by state securities laws, (i) such Shares are registered for
resale under the Securities Act, (ii) in connection with a sale transaction,
such holder provides the Company with an opinion of counsel, in a generally
acceptable form, to the effect that a public sale, assignment or transfer of
such Shares may be made without registration under the Securities Act, or (iii)
such holder provides the Company with reasonable assurances that such Shares can
be sold pursuant to Rule 144 promulgated under the Securities Act without any
restriction as to the number of securities acquired as of a particular date that
can then be immediately sold. Notwithstanding the removal of the legend set
forth above in the event the Shares are registered for resale on an effective
registration statement, the Company reserves the right to affix a legend on
certificates representing such Shares that any selling shareholder must comply
with the prospectus delivery requirements of the Securities Act in connection
with any resale. The Company shall bear the cost of the removal of any legend as
anticipated by this Section 7.

         8. OTHER COVENANTS OF THE COMPANY.

                  8.1 FURNISHING OF INFORMATION. As long as Purchaser owns
Shares, the Company covenants to timely file (or obtain extensions in respect
thereof and file within the applicable grace period) all reports required to be
filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of
the Exchange Act. If at any time prior to the date on which Purchaser may resell
all of its Shares without volume restrictions pursuant to Rule 144(k)
promulgated under the Securities Act (as determined by counsel to the Company
pursuant to a written opinion letter to such effect, addressed and acceptable to
the Company's transfer agent for the benefit of and enforceable by Purchaser)
the Company is not required to file reports pursuant to such sections, it will
prepare and furnish to Purchaser and make publicly available in accordance with
Rule 144(c) promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial statements
in form and substance substantially similar to those that would otherwise be
required to be included in reports required by Section 13(a) or 15(d) of the
Exchange Act in the time period that such filings would have been required to
have been made under the Exchange Act. The Company further covenants that it
will take such further action as Purchaser may reasonably request, all to the
extent required from time to time to enable Purchaser to sell its Shares without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 promulgated under the Securities Act.

                  8.2 LISTING OF SHARES. The Company shall, if required by any
applicable listing agreement, (a) not later than the Effective Date, prepare and
file with any national securities exchange, market or trading facility on which
the Common Stock is then listed an additional shares listing application
covering the Shares, (b) take all steps necessary to cause such shares to be
approved for listing on any other national securities exchange, market or
trading facility on which the Common Stock is then listed as soon as possible
thereafter and (c) provide to Purchaser evidence of such listing, and the
Company shall maintain the listing of its Common Stock on such exchange or
market.

                  8.3 FIRST RIGHT. The Company shall not, directly or
indirectly, without the prior written consent of Purchaser, 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 Common Stock or
securities convertible into Common Stock at a price that is less than the market
price of the Common Stock at the time of issuance of such security or investment
(a "Subsequent Financing") for a period of three hundred sixty (360) days after
the Effective Date, except (i) the granting of options or warrants to employees,
officers, directors and consultants, and the issuance of shares upon exercise of
options granted, under any stock option plan heretofore or hereinafter duly
adopted by the Company, (ii) shares issued upon exercise of any currently
outstanding warrants or options and upon conversion of any currently outstanding
convertible debenture, in each case disclosed in Section 4.4 or Schedule 4.4,
(iii) securities issued in connection with the capitalization or creation of a
joint venture with a strategic partner, (iv) shares issued to pay part or all of
the purchase price for the acquisition by the Company of a person (which, for
purposes of this clause (iv), shall not include an individual or group of
individuals), and (v) shares issued in a bona fide public offering by the
Company of its securities, unless (A) the Company delivers to Purchaser a
written notice (the "Subsequent Financing Notice") of its intention to effect
such Subsequent Financing, which Subsequent Financing Notice shall describe in
reasonable detail the proposed terms of such Subsequent Financing, the amount of
proceeds intended to be raised thereunder, the person with whom such Subsequent
Financing shall be effected, and attached to which shall be a term sheet or
similar document relating thereto and (B) Purchaser shall not have notified the
Company by 5:00 p.m. (New York time) on the fifteenth fifth(5th15th) Business
Day after its receipt of the Subsequent Financing Notice of its willingness to
provide, subject to completion of mutually acceptable documentation, financing
to the Company on substantially the terms set forth in the Subsequent Financing
Notice. If Purchaser shall fail to notify the Company of its intention to enter
into such negotiations within such time period, then the Company may effect the
Subsequent Financing substantially upon the terms and to the persons (or
affiliates of such persons) set forth in the Subsequent Financing Notice;
provided that the Company shall provide Purchaser with a second Subsequent
Financing Notice, and Purchaser shall again have the right of first refusal set
forth above in this Section 8.3, if the Subsequent Financing subject to the
initial Subsequent Financing Notice shall not have been consummated for any
reason on the terms set forth in such Subsequent Financing Notice within thirty
(30) Business Days after the date of the initial Subsequent Financing Notice
with the person (or an affiliate of such person) identified in the Subsequent
Financing Notice. The rights granted to Purchaser in this Section 8.3 are not
subject to any prior right of first refusal given to any other person except as
disclosed on Schedule 4.4.

<PAGE>

                  8.4 CERTAIN AGREEMENTS. (a) The Company covenants and agrees
that it will not, without the prior written consent of Purchaser, enter into any
subsequent or further offer or sale of Common Stock or securities convertible
into Common Stock with any third party until the date which is one hundred
eighty (180) days after the Effective Date, unless all of the Initial Shares and
Additional Shares held by the Purchaser have been redeemed by the Company
pursuant to Section 8.9 within ten (10) calendar days of the closing of such
subsequent offer or sale.

                  (b) The provisions of Section 8.4(a) will not apply to: (w)
Common Stock issued pursuant to Rule 144, provided the holder thereof is
required to hold such Common Stock for at least two years from the date of
issuance; (x) a secondary public offering of shares of Common Stock at market;
or (y) the issuance of securities (other than for cash) in connection with a
merger, consolidation, sale of assets, disposition or the exchange of the

further, that such securities would not be included in the Registration
Statement relating to the Initial Shares and a registration statement in respect
of such stock shall not be filed prior to sixty (60) days after the Effective
Date.

                  8.5 LIMITATION ON ISSUANCE OF COMMON STOCK. The Company shall
not issue an aggregate number of Shares under this Agreement that exceeds 19.9%
of the shares of Common Stock issued and outstanding on the date of the Initial
Closing (the "Share Limitation"). If, pursuant to this Agreement the Company
otherwise would be required to issue a number of shares of Common Stock that
exceeds the Share Limitation, then Purchaser shall have the right to require the
Company to (i) pay in lieu of issuance of each additional Share the amount as
determined according to the following formula: (a) for each additional shares
issuable for the First Repricing Period: ((1.40 x $2.25) - First Repricing
Price) x (# of additional First Repriced Shares); (b) for each additional shares
issuable for the Second Repricing Period: ((1.425 x $2.25) - Second Repricing
Price) x (# of additional Second Repriced Shares); and (c) for each additional
shares issuable for the Third Repricing Period: ((1.45 x $2.25) - Third
Repricing Price) x (# of additionalThird Repriced Shares); or (ii) require the
Company to issue Repricing Shares at a price equal to the average of the closing
bid price per share of Common Stock for the last five (5) consecutive trading
days during a Repricing Period (subject to certain equitable adjustments for
certain events occurring during such period).

<PAGE>

                  8.6 AVAILABLE SHARES. The Company shall have at all times
authorized and reserved for issuance, free from preemptive rights, shares of
Common Stock sufficient to yield the number of shares of Common Stock issuable
as may be required to issue the Repriced Shares.

                  8.7 CHANGE OF CONTROL. The Company shall not enter into any
agreement or understanding which may, directly or indirectly, cause or effect a
change in "control" as defined in Rule 405 under the Securities Act of 1933,
without the prior written consent of the Investor

                  8.8 REIMBURSEMENT. If (i) Purchaser, other than by reason of
its gross negligence or willful misconduct, becomes involved in any capacity in
any action, proceeding or investigation brought by any shareholder of the
Company, in connection with or as a result of the consummation of the
transactions contemplated by the Transaction Documents, or if Purchaser is
impleaded in any such action, proceeding or investigation by any person, or (ii)

the federal securities laws, becomes involved in any capacity in any action,
proceeding or investigation brought by the SEC against or involving the Company
or in connection with or as a result of the consummation of the transactions
contemplated by the Transaction Documents, or if Purchaser is impleaded in any
such action, proceeding or investigation by any person, then in any such case,
the Company will reimburse Purchaser for its reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith, as such expenses are incurred. In addition, other than with respect
to any matter in which Purchaser is a named party, the Company will pay to
Purchaser the charges, as reasonably determined by Purchaser, for the time of
any officers or employees of Purchaser devoted to appearing and preparing to

law. Nothing in this Section 9 shall affect in any way Purchaser's obligations
and agreement to comply with all applicable securities laws upon resale of the
Shares.

                  9.2 [Intentionally Omitted]

                  9.3 TRANSMISSION OF CERTIFICATES. The Company will transmit
the certificates representing the unlegended securities ("Unlegended Shares") to
be issued to Purchaser via express courier, by electronic transfer or otherwise,
within three (3) Business Days after receipt by the Company of the certificate
representing the legended Common Stock, and a representation by Purchaser that
such shares have been sold in accordance with the provisions of the Securities
Act (the "Delivery Date").

                  9.4 DELAY. The Company understands that a delay in the
issuance of the Unlegended Shares beyond the Delivery Date could result in
economic loss to Purchaser. On and after the Effective Date as compensation to
Purchaser for such loss, the Company agrees to pay late payments to Purchaser
for late issuance of Unlegended Shares in accordance with the following schedule
(where "No. of Days Late" is defined as the number of days beyond five (5)
Business Days from Delivery Date):

                                          Late Payment For Each
                  No. of Days Late        $10,000 of Common Stock
                  ----------------        -----------------------

                             1                 $100
                             2                 $200
                             3                 $300
                             4                 $400
                             5                 $500
                             6                 $600
                             7                 $700
                             8                 $800
                             9                 $900
                            10                 $1,000
                           >10                 $1,000 +$200 for each Business
                                                        Day Late beyond 10 days

The Company shall pay any payments incurred under this Section 9.4 in
immediately available funds upon demand. Nothing herein shall limit Purchaser's
right to pursue actual damages for the Company's failure to issue and deliver
the Unlegended Shares to Purchaser, except to the extent that such late payments
shall constitute payment for and offset any such actual damages alleged by
Purchaser, and any Buy In Adjustment Amount (as defined below).

                                       23
<PAGE>

                  9.5 COVER. If the Company fails for any reason to deliver the
Unlegended Shares after such Delivery Date and the holder of the Initial Shares
(a "Holder") purchases, in an open market transaction or otherwise, shares of
Common Stock (the "Covering Shares") in order to make delivery in satisfaction
of a sale of Common Stock by such Holder (the "Sold Shares"), which delivery
such Holder anticipated to make using the Unlegended Shares (a "Buy-In"), then
the Company shall pay to such Holder, in addition to all other amounts
contemplated in other provisions of the Transaction Documents, and not in lieu
thereof, the Buy-In Adjustment Amount (as defined below). The "Buy-In Adjustment
Amount" is the amount equal to the excess, if any, of (x) such Holder's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (y) the net proceeds (after brokerage commissions, if any) received by such
Holder from the sale of the Sold Shares. The Company shall pay the Buy-In
Adjustment Amount to such Holder in immediately available funds immediately upon
demand by such Holder. By way of illustration and not in limitation of the
foregoing, if such Holder purchases Covering Shares having a total purchase
price (including brokerage commissions) of $11,000 to cover a Buy-In with
respect to shares of Common Stock that it sold for net proceeds of $10,000, the
Buy-In Adjustment Amount that the Company will be required to pay to such Holder
will be $1,000.

                  9.6 ELECTRONIC TRANSFER. In lieu of delivering physical
certificates representing the Unlegended Shares issuable upon conversion,
provided the Company's transfer agent is participating in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer program, upon request of
Purchaser and its compliance with the provisions contained in this paragraph, so
long as the certificates therefor do not bear a legend and Purchaser thereof is
not obligated to return such certificate for the placement of a legend thereon,
the Company shall use its best efforts to cause its transfer agent to
electronically transmit the Common Stock to Purchaser by crediting the account
of Purchaser's Prime Broker with DTC through its Deposit Withdrawal Agent
Commission system.

                  9.7 The Company will authorize its transfer agent to give
information relating to the Company directly to the Purchaser or the Purchaser's
representatives upon the request of the Purchaser or any such representative, to
the extent such information relates to (i) the status of shares of Common Stock
issued or claimed to be issued to the Purchaser, or (ii) the number of
outstanding shares of Common Stock of all stockholders as of a current or other
specified date. The Company will provide the Purchaser with a copy of the
authorization so given to the transfer agent.

                  9.8 Subject to the completeness and accuracy of the Buyer's
representations and warranties herein, and following the expiration of any
applicable Distribution Compliance Period (as those terms are defined in
Regulation S), the Company, shall, at its expense, take all necessary action
(including the issuance of an opinion of counsel) to assure that the Company's
transfer agent shall issue stock certificates without restrictive legend or stop
orders in the name of Purchaser (or its nominee (being a non-U.S. Person) or
such non-U.S. Persons as may be designated by Buyer). Nothing in this Section,
however, shall affect in any way Buyer's or such nominee's obligations and
agreement to comply with all applicable securities laws upon resale of the
Common Stock or the Reset Shares.

         10. CLOSING DATE.

                  10.1 The closing of the issuance and sale of the Initial
Shares shall occur on the date (the "Closing Date"), which is the first Business
Day after the fulfillment or waiver of all closing conditions pursuant to

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

                  11.4 There shall not be in effect any law, rule or regulation
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained.

                                       25

         12. CONDITIONS TO PURCHASER'S OBLIGATION TO PURCHASE.

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

                  12.1 The existing S-3 Registration Statement shall have been
declared effective by the SEC;

                  12.2 Acceptance by the Company of this Agreement for the sale
of the Initial Shares, as indicated by the Company's execution and delivery of
this Agreement;

                  12.3 Delivery by the Company to the Escrow Agent of the
Certificate in accordance with this Agreement;

                  12.4 The accuracy in all material respects on the Closing Date
of the representations and warranties of the Company contained in this Agreement
as if made on the Closing Date and the performance by the Company on or before
the Closing Date of all covenants and agreements of the Company required to be
performed on or before the Closing Date; and

                  12.5 On the Closing Date, Purchaser having received an opinion
of counsel for the Company, dated the Closing Date, in form, scope and substance
reasonably satisfactory to Purchaser, to the effect set forth hereto and the
Registration Rights Agreement, if applicable.

                  12.6 No statute, rule, regulation, executive order, decree,
ruling or injunction shall be enacted, entered, promulgated or endorsed by any
court or governmental authority of competent jurisdiction which prohibits or
adversely effects any of the transactions contemplated by the Transaction
Documents, and no proceeding or investigation shall have been commenced or
threatened which may have the effect of prohibiting or adversely effecting any
of the transactions contemplated by the Transaction Documents.

                  12.7 From and after the date hereof to and including the
Closing Date, the trading of the Common Stock shall not have been suspended by
the SEC, or the AMEX and trading in securities generally on the New York Stock
Exchange or NASDAQ shall not have been suspended or limited, nor shall minimum
prices have been established for securities traded on NASDAQ, nor shall there be
any outbreak or escalation of hostilities involving the United States or any
material adverse change in any financial market that in either case in the
reasonable judgment of Purchaser makes it impracticable or inadvisable to
purchase the Initial Shares, as the case may be.
