THIS SECURITIES PURCHASE AGREEMENT (the "Agreement"), dated as of     , 2002,

                           ------
Amount (as defined in Section 7(s) hereto), if any (such difference being the
"Aggregate Principal Amount"), (such notes, in the form attached hereto as
Exhibit B, as the same may be amended, modified or supplemented from time to
- ---------
time in accordance with the terms thereof, the "Notes") that shall be
convertible into shares of the common stock, no par value (the "Common Stock"),

                                         ---------
modified or supplemented from time to time in accordance with the terms thereof,
the "Warrants"). The shares of Common Stock issuable upon exercise of the Notes
are referred to herein collectively as the "Conversion Shares." The shares of
Common Stock issuable upon exercise of the Warrants are referred to herein as
the "Warrant Shares," and the Conversion Shares and the Warrant Shares are
referred to herein as the "Underlying Shares." The Notes, the Warrants, and the
Underlying Shares are referred to herein as the "Securities."
B.     Contemporaneously  with the execution and delivery of this Agreement, the
parties hereto are executing and delivering a Registration Rights Agreement
substantially in the form attached hereto as Exhibit D (as the same may be
amended, modified or supplemented from time to time in accordance with the terms
thereof, the "Registration Rights Agreement") pursuant to which the Company has
agreed to provide the Purchasers with the benefit of certain registration rights
with respect to the Underlying Shares under the Securities Act of 1933, as

                                                           ----------
(each  an  "ASSIGNMENT  OF  RIGHTS  AGREEMENT")(which  Schedule  B  shall  be
                                                       -----------

NOW THEREFORE, in consideration of the promises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and

PURCHASE AND SALE OF NOTES AND WARRANTS

Closing of Notes and Warrants
- -----------------------------
Upon the satisfaction (or waiver) of the conditions set forth in Sections 5 and
6 of this Agreement, the Company shall issue and sell to each Purchaser, and
each Purchaser severally and not jointly agrees to purchase from the Company,
the respective principal amount of Notes, together with the related Warrants,
equal to the product of (A) the percentage set forth opposite such Purchaser's
name on the Schedule of Purchasers attached hereto as Exhibit A multiplied by
                                                      ---------
(B) the Aggregate Principal Amount (the "Closing"). The Company shall issue to
each Purchaser $1,000 principal amount (or such other amount as specified by any
such Purchaser) of the Notes and Warrants to purchase        Warrant Shares for
                                                      ------
each $1,000 tendered by such Purchaser (subject to adjustment for stock splits,
stock dividends and similar transactions). The conversion price for the Notes
and the exercise price (the "Conversion/Exercise Price") for the Warrants shall
be 105.19% of the Closing Price determined in the manner set forth in Section
1(a)(3) below. The date and time of the Closing (the "Closing Date") shall be
12:00 p.m., California time, on August 14, 2002 (or such other date as the
parties may specify), subject to the satisfaction (or waiver) of the conditions
set forth in Sections 5 and 6 of this Agreement. The Closing shall occur on the
Closing Date at the offices of Wilson Sonsini Goodrich & Rosati, 650 Page Mill

Financial Markets for the one (1) Trading Day immediately preceding the date
hereof or (ii) the average of the closing bid price of the Company's Common
Stock as quoted on Bloomberg Financial Markets for each of the five (5)
consecutive Trading Days immediately preceding the date hereof. A "Trading Day"
means a day during which trading in securities generally occurs on the Nasdaq
National Market or, if the Common Stock is not quoted on the Nasdaq National
Market, on the principal other national or regional securities exchange on which
the Common Stock then is listed or, if the Common Stock is not listed on a
national or regional securities exchange, on the National Association of
Securities Dealers Automated Quotation System, on the principal other market on
which the Common Stock is then traded; provided, however, that "Trading Day
shall not include any day (an "excluded day") during which trading in the Common
Stock is suspended for more than three hours between 9:30 a.m. (New York time)
and 4:00 p.m. (New York time).

Form  of  Payment.  On  the  Closing Date, (i) each Purchaser shall pay the
- -----------------
Company for the Notes and the Warrants to be issued and sold to such Purchaser
on such Closing Date, by wire transfer of immediately available funds in
accordance with the Company's written wire instructions attached hereto on
Schedule A, less reasonable expenses to the extent required by Section 4(g) of
- ----------
this Agreement and (ii) the Company shall deliver to each Purchaser properly
authenticated Notes representing the principal amount of Notes and the
corresponding number of Warrants, duly executed on behalf of the Company and
registered in the name of such Purchaser, that the Purchaser is purchasing from
the Company pursuant to this Agreement.

PURCHASER'S  REPRESENTATIONS  AND  WARRANTIES. Each Purchaser represents and
warrants to the Company with respect to only itself that as of the date hereof
and the Closing Date:


                                                                             -2-

Investment Purpose.  Such Purchaser (i) is acquiring the Notes and the Warrants,
- ------------------
(ii) upon conversion of the Notes owned by it, will acquire the Conversion
Shares then issuable upon conversion thereof, and (iii) upon exercise of the
Warrants held by it, will acquire the Warrant Shares then issuable upon exercise
thereof for its own account for investment only and not with a view towards, or
for resale in connection with, the public sale or distribution thereof, except
pursuant to sales registered or exempted under the Securities Act; provided,
                                                                   --------
however, that by making the representations herein, such Purchaser does not
- -------
agree to hold any of the Securities for any minimum or other specific term and
reserves the right to dispose of the Securities at any time; provided, further,
                                                             --------  -------
that such disposition shall be in accordance with or pursuant to a registration
statement or an exemption under the Securities Act.

Accredited Investor Status.  Such Purchaser is an "accredited investor" as that
- --------------------------
term is defined in Rule 501(a) of Regulation D under the Securities Act as of
the date of this Agreement and was not organized for the specific purpose of
acquiring the Securities.

Reliance on Exemptions.  Such Purchaser understands that the Securities are
- ----------------------
being offered and sold to it in reliance on specific exemptions from the
registration requirements of the United States federal and state securities laws
and that the Company is relying upon the truth and accuracy of, and such
Purchaser's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Purchaser set forth herein and in the
applicable Note or Warrant in order to determine the availability of such
exemptions and the eligibility of such Purchaser to acquire the Securities.

Information.  Such Purchaser believes it (i) has been furnished with or believes
- -----------
it has had full access to all of the information that it considers necessary or
appropriate for deciding whether to purchase the Securities, (ii) has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Securities, (iii) can bear the
economic risk of a total loss of its investment in the Securities and (iv) has
such knowledge and experience in business and financial matters so as to enable
it to understand the risks of and form an investment decision with respect to
its investment in the Securities. Neither such inquiries nor any other due
diligence investigations conducted by such Purchaser or its advisors, if any, or
its representatives shall limit, modify, amend or affect the Company's
representations and warranties contained in this Agreement and the Purchaser's
right to rely thereon.

No Governmental Review. Such Purchaser understands that no United States federal
- ----------------------
or state agency or any other government or governmental agency has passed on or
made any recommendation or endorsement of the Securities or the fairness or
suitability of an investment in the Securities nor have such authorities passed
upon or endorsed the merits of the offering of the Securities.

Transfer or Resale.  Such Purchaser understands that, except as provided in the
- ------------------
Registration Rights Agreement, none of the Securities have been or will be
registered under the Securities Act or any state securities laws, and the
Securities may not be offered for sale, sold, assigned or transferred without
registration under the Securities Act or an exemption therefrom and that, in the
absence of an effective registration statement under the Securities Act, such
Securities may only be sold under certain circumstances as set forth in the
Securities Act.


                                                                             -3-

Legends.
- -------
Such Purchaser understands that, until the end of the holding period under Rule
144(k) of the Securities Act (or any successor provision), such Notes and
Warrants (and all securities issued in exchange therefor or in substitution
thereof, other than Underlying Securities, which shall bear the legend set forth
in Section 2(g)(2) of this Agreement, if applicable) shall bear a legend in
substantially the following form:

          THE  SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
          THE  SECURITIES  ACT  OF  1933,  AS  AMENDED, OR APPLICABLE STATE
          SECURITIES  LAWS.  THE  SECURITIES  MAY  NOT BE OFFERED FOR SALE,
          SOLD,  TRANSFERRED,  ASSIGNED,  PLEDGED  OR  HYPOTHECATED  IN THE
          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
          SECURITIES  LAWS  OR  AN  EXEMPTION  THEREFROM.
The legend set forth above shall be removed and the Company shall issue a new
Note or Warrant, as appropriate, of like tenor and aggregate principal amount or
number of shares, as appropriate, and which shall not bear the restrictive
legends required by this Section 2(g)(1), (i) if, in connection with a sale
transaction, such holder provides the Company with an opinion of counsel
reasonably acceptable to the Company to the effect that a public sale,
assignment, pledge or transfer of the Notes or Warrants, as appropriate, may be
made without registration under the Securities Act, or (ii) upon expiration of
the two-year holding period under Rule 144(k) of the Securities Act (or any
successor rule). The Company shall not require such opinion of counsel for the
sale of Securities in accordance with Rule 144 of the Securities Act in the
event that the Seller provides such representations that the Company shall
reasonably request confirming compliance with the requirements of Rule 144.

Such Purchaser understands that, until the end of the holding period under Rule
144(k) of the Securities Act (or any successor provision) with respect to the
Underlying Shares issued upon conversion of the Notes or exercise of the
Warrants, as the case may be, any stock certificate representing Underlying
Shares issued upon conversion of the Notes or exercise of the Warrants shall
bear a legend in substantially the following form unless the Notes submitted for
conversion or the Warrants submitted for Cashless Exercises (as defined in the
Warrants), as the case may be, do not bear the legend specified in Section
2(g)(1):

          THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE HAVE NOT BEEN
          REGISTERED  UNDER  THE  SECURITIES  ACT  OF  1933, AS AMENDED, OR
          APPLICABLE  STATE  SECURITIES  LAWS.  THE  SECURITIES  MAY NOT BE
          OFFERED  FOR  SALE,  SOLD,  TRANSFERRED,  ASSIGNED,  PLEDGED  OR
          HYPOTHECATED  IN  THE  ABSENCE  OF  AN  EFFECTIVE  REGISTRATION
          STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED,  OR  AN  EXEMPTION  THEREFROM.


                                                                             -4-

The legend set forth above shall be removed and the Company shall issue the
Underlying Securities without such legend to the holder of the Underlying
Securities upon which it is stamped, (i) if such Underlying Securities have been
resold or transferred pursuant to the registration statement contemplated by the
Registration Rights Agreement and the registration statement was effective at
the time of such transfer, (ii) if, in connection with a sale transaction, such
holder provides the Company with an opinion of counsel reasonably acceptable to
the Company to the effect that a public sale, assignment, pledge or transfer of
the Securities may be made without registration under the Securities Act, or
(iii) upon expiration of the two-year period under Rule 144(k) of the Securities
Act (or any successor rule).  The Company shall not require such opinion of
counsel for the sale of Securities in accordance with Rule 144 of the Securities
Act, provided that the Seller provides such representations that the Company
shall reasonably request confirming compliance with the requirements of Rule
144.
Such Purchaser understands that, in the event Rule 144(k) as promulgated under
the Securities Act (or any successor rule) is amended to change the two-year
period under Rule 144(k) (or the corresponding period under any successor rule),
(i) each reference in Sections 2(g)(1) and 2(g)(2) of this Agreement to "two (2)
years" or the "two-year period" shall be deemed for all purposes of this
Agreement to be references to such changed period, and (ii) all corresponding
references in the Securities shall be deemed for all purposes to be references
to the changed period, provided that such changes shall not become effective if
they are otherwise prohibited by, or would otherwise cause a violation of, the
then-applicable federal securities laws.

Authorization; Enforcement; Validity. The Transaction Documents have been
- ------------------------------------
duly and validly authorized, executed and delivered on behalf of such Purchaser
and are valid and binding agreements of such Purchaser enforceable against such
Purchaser in accordance with their terms, subject as to enforceability to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law) and to applicable bankruptcy,
insolvency, reorganization, moratorium, liquidation and other similar laws
relating to, or affecting generally, the enforcement of applicable creditors'
rights and remedies and except as the indemnification agreements of such
Purchasers may be legally unenforceable.

Residency.  Such Purchaser is a resident of that country or state specified in
- ---------
its address on the Schedule of Purchasers attached hereto as Exhibit A.
                                                             ---------

Additional Acknowledgement.  Each Purchaser acknowledges that it has
- --------------------------
independently evaluated the merits of the transactions contemplated by this
Agreement, the Notes, the Registration Rights Agreement and the Warrants, that
it has independently determined to enter into the transactions contemplated
hereby and thereby, that it is not relying on any advice from or evaluation by
any other Purchaser, and that it is not acting in concert with any other
Purchaser in making its purchase of securities hereunder. The Purchasers and, to
its knowledge, the Company agree that the Purchasers have not taken any actions
that would deem such Purchasers to be members of a "group" for purposes of
Section 13(d) of the Exchange Act. With the exception of Subsection 2(h), the
Purchasers' representations and warranties made in this Section 2 are made
solely for the purpose of permitting the Company to make a determination that
the offer and sale of the Notes and Warrants pursuant to this Agreement complies


                                                                             -5-

with applicable United States federal and state securities laws and not for any
other purpose. Accordingly, other than Subsection 2(h), the Company should not
rely on such representations and warranties for any other purpose.

REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and
warrants to each of the Purchasers that as of the date hereof subject to such
exceptions as set forth in a Disclosure Schedule:

Organization and Qualification.  The Company and its "Subsidiaries" (which, for
- ------------------------------
purposes of this Agreement, means any entity of which the Company, directly or
indirectly, owns a majority of the capital stock or other equity or similar
interests) are corporations, partnerships or limited liability companies duly
organized and validly existing in good standing under the laws of the
jurisdiction in which they are incorporated or organized, and have the requisite
corporate or other power and authority to own their properties and to carry on
their business as now being conducted. Copies of the Company's articles of
incorporation and bylaws, and all amendments thereto, have been filed as
exhibits to the Company's SEC Documents (as defined below), are in full effect
and have not been modified. Each of the Company and its Subsidiaries is duly
qualified as a foreign corporation or partnership to do business and is in good
standing in every jurisdiction in which its ownership of property or the nature
of the business conducted and proposed to be conducted by it makes such
qualification necessary, except to the extent that the failure to be so
qualified or be in good standing would not have a Material Adverse Effect, and
no proceeding has been instituted in any such jurisdiction revoking, limiting or
curtailing, or seeking to revoke, limit or curtail, such qualification. As used
in this Agreement, "Material Adverse Effect" means any material adverse effect
on the business, properties, assets, operations, prospects, results of
operations or financial condition of the Company and its Subsidiaries, taken as
a whole, or on the transactions contemplated hereby or by the agreements and
instruments to be entered into in connection herewith, or on the authority or
ability of the Company to perform its obligations under the Transaction
Documents. A complete list of Subsidiaries is set forth on Schedule 3(a).
                                                           -------------

Authorization; Enforcement; Validity.  The Company has all requisite corporate
- ------------------------------------
power and authority to enter into and perform its obligations under each of the
Transaction Documents, and to issue the Securities in accordance with the terms
hereof and thereof. The execution and delivery of the Transaction Documents by
the Company and the consummation by it of the transactions contemplated hereby
and thereby have been duly authorized by the Company's Board of Directors, and
no further consent or authorization is required of the Company's Board of
Directors or shareholders. The Transaction Documents have been duly executed and
delivered by the Company and constitute the valid and binding obligations of the
Company, enforceable against the Company in accordance with their terms, except
as such enforceability may be limited by general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) or applicable bankruptcy, insolvency, reorganization,
moratorium, liquidation or similar laws relating to, or affecting generally, the
enforcement of creditors' rights and remedies. Each of the Assignment of Rights
Agreements constitutes the valid and binding obligations of the person listed on
Schedule B that is a party thereto, enforceable against such person in
- ----------
accordance with its terms, except as such enforceability may be limited by
general principles of equity (regardless of whether such


                                                                             -6-

enforceability is considered in a proceeding in equity or at law) or applicable
bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws

remedies.

No Conflicts. The execution, delivery and performance of the Transaction
- ------------
Documents by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby (including, without limitation, the reservation

Agreement, the representations and warranties of the Company and the Purchasers

- ---------
Company shall file a Form 8-K describing the terms of the transactions
contemplated by the Transaction Documents in the form required by the 1934 Act,
and attaching the material Transaction Documents (including, without limitation,
this Agreement, the form of Note, the form of Warrant and the Registration
Rights Agreement, provided that the signature pages and all references to the
names of the Purchasers shall be redacted) as exhibits to such filing (including
all attachments, the "8-K Filing").  From and after the filing of the 8-K Filing
with the SEC, no Purchaser shall be in possession of any material nonpublic
information received from the Company, any of its subsidiaries or any of its
respective officers, directors, employees or agents, that is not disclosed in
the 8-K Filing.  The Company shall not, and shall cause each of its Subsidiaries
and its and each of their respective officers, directors, employees and agents,
not to, provide any Purchaser with any material nonpublic information regarding
the Company or any of its Subsidiaries from and after the filing of the 8-K
Filing with the SEC without the express written consent of such Purchaser.
Subject to the foregoing, neither the Company nor any Purchaser shall issue any
press releases or any other public statements with respect to the transactions
contemplated hereby; provided, however, that the Company shall be entitled,
without the prior approval of any Purchaser, to make any press release or other
public disclosure with respect to such transactions (i) in substantial
conformity with the 8-K Filing and contemporaneously therewith and (ii) as is
required by applicable law and regulations (provided that in the case of clause
(i) each Purchaser shall be consulted by the Company in connection with any such
press release or other public disclosure prior to its release).  No press
release by the Company shall disclose the identity of any Purchaser without such
Purchaser's prior written consent.  The Company shall have the right to approve
before issuance any press releases or any other public statements with respect
to the transactions contemplated by the Transaction Documents.

Termination.  In the event that the Closing shall not have occurred with respect
- -----------
to a Purchaser on or before 15 Business Days from the date hereof due to the
Company's or such Purchaser's failure to satisfy the conditions set forth in
Sections 5 and 6 of this Agreement (and the nonbreaching party's failure to
waive such unsatisfied conditions), the nonbreaching party shall have the option
to terminate this Agreement with respect to such breaching party at the close of
business on such date without liability of any party to any other party, and the
Company shall return any and all funds paid hereunder to the applicable
Purchaser no later than the close of business on the Business Day following such
termination; provided, however, that if this Agreement is terminated pursuant to
this Section 7(n), the Company shall remain obligated to reimburse any
nonbreaching Buyer for the expenses described in Section 4(f) of this Agreement.


                                                                           -20-

Placement Agent.  The Company acknowledges that it has engaged SG Cowen as
- ---------------
placement agent in connection with the sale of the Notes and the Warrants.  The
Company shall be responsible for the payment of all placement agent's fees,
financial advisory fees, or brokers' commissions (other than for persons engaged
by any Purchaser or its investment advisor) relating to or arising out of the
transactions contemplated hereby.  The Company shall pay, and hold each
Purchaser harmless against, any liability, loss or expense (including, without
limitation, attorney's fees and out-of-pocket expenses) arising in connection
with any such claim.

Remedies.  Each Purchaser and each holder of the Securities shall have all
- --------
rights and remedies set forth in the Transaction Documents and all rights and
remedies which such holders have been granted at any time under any other
agreement or contract and all of the rights which such holders have under any
law.  Any person having any rights under any provision of this Agreement shall
be entitled to enforce such rights to recover damages by reason of any breach of
any provision of this Agreement and to exercise all other rights granted by law.
Furthermore, the Company recognizes that in the event that it fails to perform,
observe, or discharge any or all of its obligations under this Agreement, any
remedy at law may prove to be inadequate relief to the Purchasers.  The Company
therefore agrees that the Purchasers shall be entitled to seek temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages and without posting a bond or other security.

Indemnification.  In consideration of each Purchaser's execution and delivery of
- ---------------
the Transaction Documents and in addition to all of the Company's other
obligations under the Transaction Documents, the Company shall defend, protect,
indemnify and hold harmless each Purchaser and each other holder of the
Securities and all of their stockholders, officers, directors, employees and
direct or indirect investors and any of the foregoing persons' agents or other
representatives (including, without limitation, those retained in connection
with the transactions contemplated by this Agreement) (collectively, the
"INDEMNITEES") from and against any and all actions, causes of action, suits,
claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including
reasonable attorneys' fees and disbursements (the "INDEMNIFIED LIABILITIES"),
incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate, instrument or
document contemplated hereby or thereby, (b) any breach of any covenant,
agreement or obligation of the Company contained in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby, or
(c) any cause of action, suit or claim brought or made against such Indemnitee
(other than a cause of action, suit or claim which (x) is brought or made by the
Company and (y) is not a shareholder derivative suit) and arising out of or
resulting from (i) the execution, delivery, performance or enforcement of the
Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby, or (ii) the status of such Purchaser or holder
of the Securities as an investor in the Company.  To the extent that the
foregoing undertaking by the Company may be unenforceable for any reason, the
Company shall make the maximum contribution to the payment and satisfaction of
each of the Indemnified Liabilities which is permissible under applicable law.
Except as otherwise set forth herein, the mechanics and


                                                                           -21-

procedures with respect to the rights and obligations under this Section 7(q)
shall be the same as those set forth in the Registration Rights Agreement,
including, without limitation, those procedures with respect to the settlement
of claims and the Company's rights to assume the defense of claims.

Payment Set Aside.  To the extent that the Company makes a payment or payments
- -----------------
to the Purchasers hereunder or pursuant to any of the other Transaction
Documents or the Purchasers enforce or exercise their rights hereunder or
thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside, recovered from, disgorged by or are
required to be refunded, repaid or otherwise restored to the Company, a trustee,
receiver or any other Person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff
had not occurred.
(s)     Displacement.  In the event that any of the investors signatory to the
        ------------
Securities Purchase Agreement dated January 17, 2002 (the "JANUARY PURCHASE
AGREEMENT"), by and among the Company and such investors (the "JANUARY
INVESTORS"), exercise their option provided in Section 5(g) of the January
Purchase Agreement (the "OPTION RIGHTS") such that, after given effect to the
exercise by the Purchasers of the Option Rights assigned to them pursuant to the
Assignment of Rights Agreements (the "ASSIGNED OPTIONS"), such January Purchaser
have the right to purchase a portion of the Initial Amount of the Notes (such
portion of the Initial Amount that the January Purchasers have the right to
purchase being referred to as the "DISPLACEMENT AMOUNT"), then in lieu of
purchasing such Displacement Amount each Purchaser shall be issued Warrants in
the form attached as Exhibit C hereto (in addition to those already contemplated
                     ---------
by this Agreement) exercisable for that number of shares of Company Common Stock
equal to the quotient of (i) 25% of  the product of (A) the Displacement Amount
multiplied by (B) the percentage set forth opposite such Purchaser's name on
Exhibit A hereto, divided by (ii) the Conversion/Exercise Price; provided,
- ---------                                                        --------
however, that in no event shall the Company be required to  issue (X) in excess
- -------
of 665,000 Warrant Shares pursuant to this Section 7(s) and (Y) to any
Purchasers any Warrants pursuant to this Section 7(s) exercisable for an
aggregate amount in excess of the product of (1) 665,000 Warrant Shares,
multiplied by (2) the percentage set forth opposite such Purchaser's name on
Exhibit A hereto (in the case of either (X) or (Y), subject to adjustment for
stock splits, stock dividends and other similar transactions).  The Company
shall provide the Purchasers notice (pursuant to Section 7(g) hereof) of any
exercise by the January Investors of their Option Rights, including, the amount
of the Notes for which any such Option Rights have been exercised, no later than
the Business Day immediately preceding the Closing Date, and the Purchasers
shall exercise their Assigned Rights so that they can purchase as great a
percentage as possible of the Initial Amount (and so that the Displacement
Amount will be as small as possible).


                                                                           -22-
