                            RAINING DATA CORPORATION

                       NOTE AND WARRANT PURCHASE AGREEMENT

        THIS NOTE AND WARRANT PURCHASE AGREEMENT (the "Agreement") is made as of
November 30, 2000, by and between RAINING DATA CORPORATION, a Delaware
corporation, formerly Omnis Technology Corporation (the "Company"), and ASTORIA
CAPITAL PARTNERS, L.P., a California limited partnership ("Astoria").

        WHEREAS, the Company, Raining Merger Sub, Inc., a Delaware corporation
(a subsidiary of the Company), PickAx, Inc., a Delaware corporation, and Gilbert
Figueroa as the named stockholder of PickAx, Inc. propose to enter in a business
combination in exchange for the Common Stock of the Company (the "Merger")
pursuant to an Agreement and Plan of Merger dated August 23, 2000 (the "Merger
Agreement").

        WHEREAS, as a condition of the Merger, Astoria has agreed to forgive and
cancel its note receivable from PickAx, Inc. pursuant to the terms and
conditions hereof, effective as of the Closing of the Merger.

        NOW, THEREFORE, the parties hereby agree as follows:

        1. THE NOTE AND WARRANT.

        1.1 THE NOTE AND WARRANT. In connection with the Merger, Astoria hereby
irrevocably agrees to forgive and cancel the 10% Senior Convertible Note from
PickAx, Inc. dated March 16, 2000 in the principal amount of $17,300,000,
together with all interest or other liabilities thereon (the "PickAx Note"), in
consideration of the issuance of (a) a promissory note of the Company in the
principal amount of eighteen million five hundred twenty-five thousand four
hundred sixteen dollars and sixty-seven cents ($18,525,416.67), bearing interest
at Eight Percent (8%) per annum compounded annually, executed and delivered
concurrently herewith in the form attached hereto as Exhibit A (the "Note") and
(b) a warrant to purchase 500,000 shares of Common Stock of the Company at $7.00
per share in the form attached hereto as Exhibit B (the "Warrant").

        In connection with the cancellation and forgiveness of the PickAx Note
hereunder, Astoria acknowledges and agrees that effective as of the Note Closing
(as hereinafter defined) (i) the PickAx Note and all related obligations and
liabilities are and shall be fully cancelled and forgiven and deemed fully and
forever released and discharged as to all persons or entities, automatically and
without any further act; (ii) all security interests and liens and any other
related rights which PickAx, Inc. or any affiliate thereof has granted to
Astoria with regard to the PickAx Note shall be cancelled and released and
discharged, automatically and without any further act; and (iii) to the extent
any UCC-1 financing statements evidencing any such security interest were filed,
Astoria shall promptly file UCC termination statements in the relevant
jurisdictions evidencing release and shall provide the Company with true copies
of such filings.

Astoria further will promptly execute and deliver such other agreements and
instruments in form and substance satisfactory to the Company, as the Company
may reasonably request to further evidence and effect cancellation and
forgiveness and discharge and release of the PickAx Note and the release and
discharge of the security interests and liens granted to Astoria pursuant to the
PickAx Note and any other agreement executed and delivered in connection
therewith.

        1.2 CLOSINGS. The purchase and sale of the Note and Warrant (the "Note
Closing") will take place concurrently with the Closing of the Merger at the
offices of PickAx, Inc. at 1691 Browning, Irvine, California 92606 at Closing
Date (as defined in the Merger Agreement).

        2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to Astoria as of the Note Closing that:

        2.1 ORGANIZATION, STANDING AND POWER. The Company is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware and has all requisite corporate power and authority to own, lease
and operate its properties and to carry on its business as contemplated to be
conducted (the "Business"). The Company is duly qualified and in good standing
to conduct business in each jurisdiction in which the business it is conducting,
or the operation, ownership or leasing of its properties, makes such
qualification necessary, except where the failure to be so qualified would not
result in a Material Adverse Effect (as defined herein). For purposes hereof,
the term "Material Adverse Effect" means any material adverse change in, or
material adverse effect on, the business, prospects, assets, results of
operations, value or condition (financial or otherwise) of the Company, its
subsidiaries and/or the Business (individually or taken as a whole), or any
event or circumstance which would likely prevent, hinder or materially delay the
consummation of any of the transactions contemplated by this Agreement or the
Note.

        2.2 AUTHORITY AND ENFORCEABILITY. The Company has all requisite
corporate power and authority to execute and deliver this Agreement and the Note
and to perform fully its obligations hereunder and thereunder. The execution and
delivery of this Agreement, the Note and the Warrant (the "Loan Agreements") and
the consummation of the transactions contemplated hereby and thereby have been
duly authorized by all necessary corporate action on the part of the Company.
The Loan Agreements have been duly executed and have been delivered by the
Company and, assuming the Loan Agreements constitute valid and binding
agreements of the other parties hereto and thereto, the Loan Agreements
constitute legal, valid and binding agreements and obligations of the Company,
enforceable against the Company in accordance with their respective terms,
subject to applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws now or hereafter in effect relating to creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity regardless of whether enforceability is considered in a proceeding at law
or in equity.

        2.3 OMNIS SEC REPORTS. To the best of the knowledge of the Company, the
Form 10-KSB/A of the Company for the period ended March 31, 2000, the Form
10-QSB of the Company for the period ended June 30, 2000 and the definitive
Proxy Statement of the Company in connection with the Merger ("Proxy
Statement"), in each case as filed with the Securities and Exchange Commission
("SEC") pursuant to the Exchange Act (the "Omnis SEC Reports"), complied at the
time they were filed in all material respects with applicable requirements of
the Securities Exchange Act of 1934 and the rules and regulations thereunder;
and none of such Omnis SEC Reports, as of their respective filing dates (as
amended through the date hereof), contained or, with respect to Omnis SEC
Reports filed after the date hereof and on or prior to the Closing, will contain
any untrue statement of a material fact or omitted or, with respect to such
Omnis SEC Reports filed after the date hereof and on or prior to the Closing,
will omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, subject in all respects to all disclaimers and
qualifications set forth in each of such Omnis SEC Reports; provided, however,
that the foregoing representations and warranties of the Company shall not apply
to and are not made with respect to any information included or incorporated by
reference into the Proxy Statement or any statements in the Proxy Statement
which are based in whole or in material part on such information that (a) has
been provided by PickAx or Astoria or any representative or agent thereof, (b)
describes the assets, capitalization, management, business or business prospects
of PickAx or Astoria, or (c) describes the assets, capitalization, management,
business or business prospects following consummation of the Merger of (i) the
Company, (ii) PickAx or any PickAx subsidiaries or (ii) the Company and PickAx
and/or any PickAx subsidiaries on a consolidated basis, including, but not
limited to, any consolidated and/or pro forma financial information.

        2.4 NO MATERIAL ADVERSE CHANGES. Except as specifically contemplated by
this Agreement, after August 10, 2000 (the date of the latest filing of Omnis
SEC Reports) through the date of the Agreement there has not been any change or
event having a material adverse effect on the Company (with the exception of (i)
the Merger and the transactions and events contemplated by the Merger Agreement
and related documents, (b) the termination of employment of certain employees of
the Company in connection with or in contemplation of the Merger and (c) facts
or conditions relating exclusively to political or economic matters of general
applicability that will adversely affect comparable entities generally).

        3. REPRESENTATIONS AND WARRANTIES OF ASTORIA. Astoria hereby represents
and warrants to the Company as of the Closing that:

        3.1 AUTHORIZATION. Astoria has full power and authority to enter into
the Loan Agreements and the Loan Agreements constitute valid and legally binding
agreement and obligations of Astoria, enforceable in accordance with their
respective terms.



                                       3
<PAGE>   4

        3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. The Note, the Warrant and the
Common Stock of the Company issuable upon exercise of the Warrant (collectively,
the "Securities") are being acquired by Astoria for investment for its own
account, and not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and Astoria has no present intention of
selling, granting any participation in, or otherwise distributing the same.
Astoria does not have any contract, undertaking, agreement or arrangement with
any person to sell, transfer or grant participation in any of the Securities to
such person or to any third person. Astoria has not been organized for the
purpose of acquiring the Securities.

        3.3 DISCLOSURE OF INFORMATION. Astoria understands that any loan to the
Company or investment in the Securities involves substantial risks. Astoria has
been given the opportunity to make a thorough investigation of the business and
activities of the Company. Astoria further has been afforded the opportunity to
obtain any additional information deemed necessary by Astoria to verify the
accuracy of any representations made or information conveyed to Astoria. Astoria
has had an opportunity to ask questions of and receive answers from the Company
or its officers concerning the Company and the terms and conditions of the
offering and sale of the Securities.

        3.4 INVESTMENT EXPERIENCE. Astoria by reason of its business and
financial experience has such knowledge, sophistication and experience in
financial and business matters and in making investment and lending decisions of
this type that it is capable of (i) evaluating the merits and risks of an
investment in the Securities and making an informed investment decision, (ii)
protecting its own interests and (iii) bearing the economic risk of such
investment, including the complete loss thereof.

        3.5 ACCREDITED INVESTOR. Astoria is an "accredited investor" within the
meaning of Rule 501(a) of Regulation D of the Securities Act of 1933
("Securities Act"), as presently in effect (excerpts of the definition of
"accredited investor" are attached as Exhibit C hereto).

        3.6 RESTRICTED SECURITIES. Astoria understands that the Securities have
not been registered under the Securities Act or state securities laws and will
be issued by reason of a specific exemption from the registration provisions of
the Securities Act and applicable state securities laws that depends upon, among
other matters, the bona fide nature of the investment intent and the accuracy of
Astoria's representations as expressed in this Agreement. Astoria further
understands that except as provided in the Warrant, the Company shall have no
obligation to register the Securities under the Securities Act or any state
securities laws or to take any action that would make available any exemption
from the registration requirements of such laws (except as set forth in the
Warrant). Astoria hereby acknowledges that because of the restrictions on
transfer or assignment of the Securities Astoria may have to bear the economic
risk of the investment commitment in the Securities for an indefinite period of
time.

        3.7 FURTHER LIMITATIONS ON DISPOSITION. In addition to the limitations
on transfer or assignment of the Warrant and shares of Common Stock issuable
upon exercise of the Warrant as described in the Warrant, Astoria will observe
and comply with the Securities Act and the rules and regulations promulgated
thereunder, as now in effect and as from time to time amended, and any
applicable state securities laws in connection with any offer, sale, pledge,
transfer or other disposition of the Securities. In furtherance of the foregoing
and without limiting any other representations and warranties in this Agreement,
Astoria will not offer to sell, exchange, transfer, pledge, or otherwise dispose
of any of the Securities unless at such time at least one of the following is
satisfied:

                (a) There is then in effect a Registration Statement under the
Securities Act as filed with the United States Securities and Exchange
Commission covering such proposed disposition; and such disposition is made in
accordance with such Registration Statement;

                (b) Such transaction shall be permitted pursuant to the
provisions of SEC Rule 144;

                (c) (i) Astoria shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and (ii) if requested by
the Company, Astoria shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company and its counsel, that such
disposition will not require registration of such shares under the Securities
Act or registration or qualification under any applicable state securities laws;
or

                (d) An authorized representative of the SEC shall have rendered
written advice to Astoria (sought by Astoria or counsel to Astoria, with a copy
thereof and of all other related communications delivered to the Company) to the
effect that the SEC would take no action with respect to the proposed sale,
transfer or other disposition if consummated; and such proposed sale, transfer
or other disposition did not violate any applicable state securities laws.

        3.8 LEGENDS.

                (a)The certificates evidencing the Securities or any substitute
therefor may bear one or more of the following legends or their substantial

                          COMMON STOCK PURCHASE WARRANT


500,000 Shares of Common Stock                                 November 30, 2000
                                                          San Carlos, California


        Reference is hereby made to that certain Note and Warrant Purchase

Delaware corporation, formerly Omnis Technology Corporation (the "Company") and
Astoria Capital Partners, L.P., a California limited partnership ("Astoria"),
the terms of which are incorporated by this reference. The term "Holder" shall

shall further refer to any subsequent permitted holder of this Warrant from time
to time.

        The Company hereby certifies that, for value received, Holder is
entitled to purchase from the Company, on or before the Expiration Date (as
defined below), up to Five Hundred Thousand (500,000) duly authorized, validly
issued, fully paid and non-assessable shares of Common Stock of the Company,

Capitalized terms used and not otherwise defined in this Common Stock Purchase
Warrant (this "Warrant") shall have the respective meanings assigned to them in

        1.1 Term of Warrant. This Warrant shall be exercisable for a period of
five (5) years after the date hereof (the expiration date for this Warrant is
hereinafter referred to as the "Expiration Date").

                                       1
<PAGE>   21

        1.3 Exercise of Warrant.

                (a) This Warrant may be exercised, in whole or in part, upon
surrender to the Company at its then principal offices in the United States of
the certificate or certificates evidencing this Warrant to be exercised,
together with the form of election to exercise attached hereto as Exhibit A duly
completed and executed, and upon payment to the Company of the aggregate Warrant
Price for the number of Warrant Shares in respect of which this Warrant is then
being exercised.

                (b) Payment of the aggregate Warrant Price may be made (i) in
cash or by cashier's or bank check or (ii) if the Stock is at the time traded on
any national securities exchange or in any United States interdealer quotation
system, by making a Cashless Exercise (as defined herein). Upon a "Cashless
Exercise" the Holder shall receive Stock on a net basis such that, without the
payment of any funds, the Holder shall surrender this Warrant in exchange for
the number of shares of Stock equal to the product of (i) the number of shares
of Stock as to which this Warrant is being exercised, multiplied by (ii) a
fraction, the numerator of which is the per share closing price of such Stock as
of the close of trading on the last trading day prior to the date of the
Cashless Exercise (or, if no such closing price is reported for such day, the
mean between the closing bid and the closing asked prices on the principal
national securities exchange or in the principal United States interdealer
quotation system on which the Stock is traded)("Trading Price") less the then
Warrant Price, and the denominator of which is said Trading Price.

                (c) Subject to Section 2 hereof, upon surrender of this Warrant,
and the duly completed and executed form of election to exercise, and payment of
the Warrant Price in cash or pursuant to the Cashless Exercise, the Company
shall cause to be issued and delivered to the Holder or such other person as the
Holder may designate in writing hereunder a certificate or certificates for the
number of full shares of Stock so purchased upon the exercise of this Warrant.
Such certificate or certificates shall be deemed to have been issued and any
person so designated to be named therein shall be deemed to have become a holder
of record of such Warrant Shares as of the date of the surrender of this
Warrant, and the duly completed and executed form of election to exercise, and
payment of the Warrant Price; provided however, that if, the date of surrender
of this Warrant and payment of the Warrant Price is not a business day, the
certificates for the Warrant Shares shall be issued as of the next business day
(whether before or after the Expiration Date), and, until such date, the Company
shall be under no duty to cause to be delivered any certificate for such Warrant
Shares or for shares of such other class of stock.

        1.4 Fractional Interests. The Company shall not be required to issue
fractions of shares of Stock on the exercise of this Warrant. If any fraction of
a share of Stock would be issuable upon the exercise of this Warrant (or any
portion thereof), the Company shall purchase such fraction for an amount in cash
equal to the same fraction of the last reported closing price of the Stock on
the NASDAQ National Market System or any other national



                                       2
<PAGE>   22

securities exchange or market on which the Stock is then listed or traded, and
if not so listed or traded, at the then fair market value of a single share of
Stock as determined in good faith by the Board of Directors of the Company,
which determination shall be binding and conclusive.

Section 2. Exchange and Transfer of Warrant and Warrant Shares.

                (a) This Warrant and the Warrant Shares have not been registered
under any securities laws and shall be subject to the rights, restrictions,
limitations, representations, warranties and covenants set forth in the Purchase
Agreement at all times. In connection therewith this Warrant hereby does bear
and any stock certificates issued pursuant to the exercise of this Warrant or
any substitute therefor shall bear the legends described in the Purchase
Agreement.

                (b) This Warrant may be transferred, in whole or in part,
without restriction, subject to receipt of an opinion from Morrison & Foerster
LLP or any other law firm satisfactory to the Company that such transfer will
not require registration or qualification under applicable securities laws (or
such registration or qualification has been effected) and as otherwise provided
in the Purchase Agreement. A transfer may be registered with the Company by
submission to it of this Warrant, together with the annexed Assignment Form
attached hereto as Exhibit B duly completed and executed. After the receipt by
the Company of this Warrant and the Assignment Form so completed and executed
and after compliance with all conditions hereunder, the Company will issue and
deliver to the transferee a new warrant (representing the portion of this
Warrant so transferred) at the same Warrant Price per share and otherwise having
the same terms and provisions as this Warrant, which the Company will register
in the new holder's name. In the event of a partial transfer of this Warrant,
the Company shall concurrently issue and deliver to the transferring holder a
new warrant that entitles the transferring holder to purchase the balance of
this Warrant not so transferred and that otherwise is upon the same terms and
conditions as this Warrant. Upon the due delivery of this Warrant for transfer,
the transferee holder shall be deemed for all purposes to have become the holder
of the portion of this Warrant so transferred, effective immediately prior to
the close of business on the date of such delivery, irrespective of the date of
actual delivery of the new warrant representing this Warrant so transferred.

                (c) In the event of the loss, theft or destruction of this
Warrant, the Company shall execute and deliver an identical new warrant to the
Holder in substitution therefor upon the Company's receipt of (i) evidence
reasonably satisfactory to the Company of such event and (ii) if requested by
the Company, an indemnity agreement reasonably satisfactory in form and
substance to the Company. In the event of the mutilation of or other damage to
this Warrant, the Company shall execute and deliver an identical new warrant to
the Holder in substitution therefor upon the Company's receipt of the mutilated
or damaged warrant.

                (d) The Company shall pay all costs and expenses incurred in
connection with the exercise, exchange, transfer or replacement of this Warrant,
including, without limitation, the costs of preparation, execution and delivery
of a new warrant and of stock certificates representing all Warrant Shares for
which the Warrant is being exercised; provided, that the Holder shall pay all
taxes payable in connection with the exercise or transfer or replacement of this
Warrant and any transfer or disposition of the Warrant Shares.

Section 3. Certain Covenants. The Company covenants that during the period this
Warrant is exercisable in accordance with its terms, the Company will (i)
reserve from its authorized and unissued Stock, a sufficient number of shares to
provide for the issuance of Stock upon exercise of this Warrant or (ii) if at
any time the number of authorized but unissued shares of Stock shall not be
sufficient to effect the exercise of this Warrant in full, in addition to such
other remedies as shall be available to the Holder, the Company will use its
best efforts to take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Stock to
such number of shares as shall be sufficient for such purposes; subject to
applicable securities laws and the limitations set forth in the Purchase
Agreement. The Company will not, by amendment of its Certificate of
Incorporation or otherwise, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant.

Section 4. Adjustment of Warrant Price and Number of Warrant Shares.

        The Warrant Price per share and the number and kind of securities
purchasable upon the exercise of this Warrant shall be subject to adjustment
from time to time upon the occurrence of certain events, as hereinafter
provided.

                (a) In case the Company shall after the date hereof (i) pay a
dividend or make a distribution on its Stock in shares of its Stock, (ii) engage
in a stock split or reverse stock split or combination of its outstanding Stock,
or (iii) issue any shares by reclassification of its Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation) without receipt of consideration, the
Warrant Price for the Shares in effect at the time of such event shall be
proportionally adjusted as herein provided so that the Holder, upon exercise of
this Warrant after such date, shall be entitled to receive the aggregate number
and kind of shares of Stock which, if this Warrant had been exercised
immediately prior to such transaction date, it would have owned upon such
exercise and been entitled to receive upon such dividend, distribution, stock
split or reverse stock split, combination or reclassification.

                (b) Whenever the Warrant Price payable upon exercise of this
Warrant is adjusted pursuant to Section 4(a) hereof, the number of Warrant
Shares purchasable upon exercise of this Warrant shall simultaneously be
adjusted by multiplying the number of Warrant Shares issuable upon exercise of
this Warrant immediately before the event that caused the adjustment by the
Warrant Price in effect as of the date of this Warrant and dividing the product
so obtained by the Warrant Price, as adjusted.



                                       4
<PAGE>   24

                (c) No adjustment in the Warrant Price shall be required unless
such adjustment would require an increase or decrease of at least 0.75% in such
price; provided however that any such adjustments not required to be made in
this Subsection shall be carried forward and taken into account in any
subsequent adjustment. For these purposes all calculations under this Section 4
shall be made to the nearest cent or to the nearest one-thousandth of a share,
as the case may be.

                (d) Whenever the Warrant Price and number of Warrant Shares is
adjusted hereunder, as herein provided, the Company shall promptly cause a
notice setting forth the adjusted Warrant Price and adjusted number of shares
issuable upon exercise of this Warrant to be mailed to the Holder. The
certificate setting forth the computation shall be signed by the Chief Financial
Officer of the Company.

                (e) In the event that at any time, as a result of any adjustment
made pursuant to the foregoing Section 4(a), the holder of this Warrant
thereafter shall become entitled to receive any shares of the capital stock of
the Company, other than Stock, thereafter the number of such other shares so
receivable upon exercise of this Warrant shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Stock contained in Section 4(a). Subject to the
foregoing exception, no adjustment shall be made hereunder for (i) any dividend
or distribution or other transaction by the Company in any class of its
preferred stock; or (ii) any changes occurring on account of the issuance of
capital stock of the Company at any time upon the exercise of any stock options,
rights or warrants or upon the conversion of any convertible securities or debt
(whether existence on or after the date of this Warrant) or other issuance of
capital stock of the Company in a private or public offering for consideration.

                (f) In the event that during the Term hereof the Company shall
issue additional shares of its Common Stock for a consideration per share
("Issue Price") less than the then applicable Warrant Price as adjusted
hereunder, then and in each such case the then existing Warrant Price shall be
reduced, as of the opening of business on the date of such issue or sale, to a
price determined by multiplying the Warrant Price by a fraction (i) the
numerator of which shall be (A) the number of shares of Common Stock deemed
outstanding (as defined below) immediately prior to such issue or sale, plus (B)
the number of shares of Common Stock which the aggregate consideration received
(as defined below) by the Company for the total number of additional shares of
Common Stock so issued would purchase at such Warrant Price and (ii) the
denominator of which shall be the number of shares of Common Stock deemed
outstanding (as defined below) immediately prior to such issue or sale plus the
total number of additional shares of Common Stock so issued. For the purposes of
the preceding sentence, the number of shares of Common Stock deemed to be
outstanding as of a given date shall be the sum of (A) the number of shares of
Common Stock actually outstanding and (B) the number of shares of Common Stock
which could be obtained through the exercise or conversion of all other rights,
options and convertible securities on the day immediately preceding the



                                       5
<PAGE>   25

given date. For these purposes no adjustment shall be made for (i) any
transaction otherwise governed by this Section 4 or by Section 5 hereunder; (ii)
any dividend or distribution or other transaction by the Company in any class of
its preferred stock; (iii) any issuance of capital stock of the Company at any
time upon the exercise of any stock options, rights or warrants by any employee
or independent contractor or other service provider, licensor, vendor or lender
of the Company; or (iv) the Merger as defined in the Purchase Agreement. For the
purpose of making any adjustment required under this Section 4(f), the
consideration received by the Company for any issue or sale of Common Stock
shall (A) to the extent it consists of cash, be computed at the net amount of
cash received by the Company after deduction of any underwriting or similar
commissions, compensation or concessions paid or allowed by the Company in
connection with such issue or sale but without deduction of any expenses payable
by the Company, and (B) to the extent it consists of property other than cash,
be computed at the fair value of that property as determined in good faith by
the Board of Directors.

Section 5. Consolidation, Merger or Sale of Assets.

        (a) In case of any consolidation of the Company with, or merger of the
Company with or into any other entity (other than a merger which does not result
in any reclassification, conversion, exchange or cancellation of outstanding
shares of Stock), or any sale or transfer of all or substantially all of the
assets of the Company or of the entity formed by such consolidation or resulting
from such merger or which acquires such assets, as the case may be, after the
date hereof, the Holder shall have the right thereafter to exercise this Warrant
for the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer by a holder of the number of shares
of Stock for which this Warrant may have been exercised immediately prior to
such consolidation, merger, sale or transfer, assuming (i) such holder of Stock
is not a person with which the Company consolidated or into which the Company
merged or which merged into the Company or to which such sale or transfer was
made, as the case may be ("Constituent Person"), or an Affiliate of a
Constituent Person and (ii) in the case of a consolidation, merger, sale or
transfer which includes an election as to the consideration to be received by
the holders, such holder of Stock failed to exercise its rights of election as
to the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer (provided however that if the kind
or amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer is not the same for each share of Stock
held immediately prior to such consolidation, merger, sale or transfer by other
than a Constituent Person or an Affiliate thereof and in respect of which such
rights of election shall not have been exercised ("Non-Electing Share"), then
for the purposes of this Section the kind and amount of securities, cash, and
other property receivable upon such consolidation, merger, sale or transfer by
each Non-Electing Share shall be deemed to be the kind and amount so receivable
per share by a plurality of the Non-Electing Shares). For purposes of this
Section 5, "Affiliate" shall have the meaning given to such term in Rule 12b-2
promulgated under the Securities and Exchange Act of 1934, as amended (the "1934
Act").



                                       6
<PAGE>   26

        (b) Adjustments for events subsequent to the effective date of such a
consolidation, merger and sale of assets shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Warrant. In any such event,
the Company shall exercise its best efforts to have effective provisions made in
the certificate or articles of incorporation of the resulting or surviving
corporation, in any contract of sale, conveyance, lease or transfer, or
otherwise so that the provisions set forth herein for the protection of the
rights of the Holder shall thereafter continue to be applicable; and any such
resulting or surviving corporation shall expressly assume the obligation to
deliver, upon exercise, such shares of stock, other securities, cash and
property. The provisions of this Section 5 shall similarly apply to successive
consolidations, mergers, sales, leases or transfers.

Section 6. Registration Rights.

        (a) Piggyback Registration. If the Company proposes to register any of
its securities at any time after the date hereof, the Company shall notify the
Holder in writing at least thirty (30) days prior to filing any such
registration statement under the Securities Act or 1933, as amended (the
"Securities Act"), for purposes of effecting a public offering of securities of
the Company (excluding registration statements relating to any employee benefit
plan or a corporate reorganization, including securities issued by the Company
in an acquisition transaction). The Holder shall have the right to include in
such registration statement all or any part of the Holder's Warrant Shares or
other securities into which the Warrant Shares have been or may be converted
("Registrable Securities"). If the Holder elects to include in any such
registration statement all or any part of the Holder's Registrable Securities,
then the Holder shall, within twenty (20) days after receipt of the
above-described notice from the Company, so notify the Company in writing, and
in such notice shall inform the Company of the number of Registrable Securities
the Holder wishes to include in such registration statement. If the Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, the Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company on or before the date set forth above with respect to offerings of
its securities, all upon the terms and conditions set forth herein.

        (b) Underwriting. If a registration statement under which the Company
gives notice under this Section is for an underwritten offering, then the
Company shall so advise the Holder. In such event, the right of the Holder to
include its Registrable Securities in a registration pursuant to this Section
shall be conditioned upon the Holder's participation in such underwriting and
the inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriter(s) selected for such
underwriting. Notwithstanding any other provision of this Agreement, if the
managing underwriter determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares (including Registrable Securities) from the
registration



                                       7
<PAGE>   27

and the underwriting, and the number of shares that may be included in the
registration and the underwriting shall be allocated, first, to the Company, and
second, to the Holder. The Holder may elect to withdraw from any offering by
written notice to the Company and the underwriter, delivered at least twenty
(20) days prior to the effective date of the registration statement. Any
Registrable Securities excluded or withdrawn from such underwriting shall be
excluded and withdrawn from the registration.

        (c) Expenses. All expenses incurred in connection with a registration
pursuant to this Section (excluding underwriters' and brokers' discounts and
commissions; and the fees and disbursements of special counsel for the Holder),
including, without limitation all federal registration and qualification fees,
"blue sky" registration and qualification fees for up to five (5) states,
printers' and accounting fees, fees and disbursements of counsel for the Company
shall be borne by the Company.

        (d) Indemnification. In the event any Registrable Securities are
included in a registration statement pursuant hereto:

                (1) By the Company. To the extent permitted by law, the Company
will indemnify and hold harmless the Holder, the partners, officers and
directors of the Holder, any underwriter (as defined in the Securities Act) for
Holder and each person, if any, who controls the Holder or underwriter within
the meaning of the Securities Act or the 1934 Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the l934 Act or other federal or state law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively, "Violations" and, individually, a "Violation"): (i)
any untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto; (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(iii) any violation or alleged violation by the Company of the Securities Act,
the 1934 Act, any federal or state securities law or any rule or regulation
promulgated under the Securities Act, the 1934 Act or any federal or state
securities law in connection with the offering covered by such registration
statement; and the Company will reimburse the Holder, each partner, officer or
director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability or action; provided however,
that the indemnity agreement contained in this subsection shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable in any such
case for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by such Holder, partner, officer, director, underwriter
or controlling person of the Holder.



                                       8
<PAGE>   28

                (2) By the Holder. To the extent permitted by law, the Holder
will indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, or underwriter
may become subject under the Securities Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by the Holder expressly for
use in connection with such registration; and the Holder will reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, or underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action; provided however,
that the indemnity agreement contained in this subsection shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; and provided further, that the total amounts
payable in indemnity by the Holder under this Section in respect of any
Violation shall not exceed the net proceeds received by the Holder in the
registered offering out of which such Violation arises.

                (3) Notice. Promptly after receipt by an indemnified party under
this Section of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section, but the omission so to deliver written
notice to the indemnifying party will not relieve it of any liability that it
may have to any indemnified party otherwise than under this Section.

                (4) Defect Eliminated in Final Prospectus. The foregoing
indemnity agreements of the Company and the Holder are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus
but eliminated or remedied in the amended prospectus on file with the SEC at the



                                       9
<PAGE>   29

time the registration statement in question becomes effective or the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified party
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

        (e) "Market Stand-Off" Agreements.

                (i) Notwithstanding any contrary provision in the Purchase
Agreement or this Warrant, the Holder agrees that such Holder shall not (A)
lend, offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, this Warrant or any shares of Stock issuable under this Warrant or
any securities convertible into or exercisable or exchangeable for this Warrant
or such Stock, or (B) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
this Warrant or such Stock or any securities convertible into or exercisable or
exchangeable for this Warrant or such Stock, whether any such transaction is to
be settled by delivery of Stock or such other securities, in cash or otherwise,
without the prior written consent of the Company during the period beginning on
the Effective Date of this Warrant and ending on March 31, 2001.

                (ii) The Holder hereby further agrees that it shall not, to the
extent Registrable Securities are not included in any registration statements
and if requested by the Company or an underwriter of securities of the Company,
sell or otherwise transfer or dispose of any Warrant Shares or securities into
which they have been or may be converted (other than to donees or partners of
the Holder who agree to be similarly bound and further subject to the prior
written consent of the Company, which shall not be unreasonably withheld) for up
to one hundred eighty (180) days following the effective date of a registration
statement of the Company filed under the Securities Act for a firm commitment
underwritten offering of newly-issued common stock of the Company; provided,
however, that all executive officers, directors and 1% shareholders of the
Company then holding Common Stock of the Company enter into similar agreements.
In order to enforce the foregoing covenant, the Company shall have the right to
place restrictive legends on the certificates representing the shares subject to
this Section and to impose stop transfer instructions with respect to the
Warrant Securities (and the Warrant Shares of every other person subject to the
foregoing restriction) until the end of such period.



                                       10

Section 7. Limitations on Rights and Obligations of the Warrant Holder. This
Warrant shall not entitle the Holder to any voting rights or dividends or any
other rights of a stockholder in the Company.

Section 8. Capital Transactions. Neither the grant of this Warrant nor the
issuance of Warrant Shares nor any other provision of this Warrant shall in any
manner limit or affect the right of the Company to adjust, reclassify,
recapitalize, restructure, reorganize or otherwise change its capital or
business structure or issue options or warrants or other rights to its
securities or to merge, consolidate, dissolve, liquidate or sell or transfer or
otherwise dispose of all or any part of its stock, business or assets at any
time.

permitted hereunder shall made pursuant to the notice provisions set forth in
the Purchase Agreement.

modified, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of such modification, waiver,
discharge or termination is sought.

Section 11. Applicable Law. This Warrant is being delivered in and shall be
construed in accordance with the laws of the State of California, without regard
to conflicts of laws principles.

Section 12. Severability. If any provision of this Warrant shall be judicially
determined to be invalid, illegal or unenforceable by a court of competent
jurisdiction, the validity, legality and enforceability of the remaining
provisions shall not in any manner be affected or impaired and shall remain in
full force and effect.

Section 13. Interpretation. Sections and section headings contained in this
Warrant are for reference purposes only, and shall not affect in any manner the
meaning of interpretation of this Warrant. Whenever the context requires,
references to the singular shall include the plural and the plural the singular
and any gender shall include any other gender. The parties acknowledge that each
party has reviewed this Warrant, and no provision of this Warrant shall be
interpreted for or against any party because such party or its representative
drafted such provision.

Section 14. Successors and Assigns. Except as otherwise expressly provided
herein and subject to any restrictions on transfer under applicable securities
laws, the provisions hereof shall inure to the benefit of and be binding upon
each of the parties; the successors and assigns of the Company; and the heirs,
devisees, executors, administrators, representatives, successors and assigns of
Holder.

                        DEFINITION OF ACCREDITED INVESTOR
           (as provided in Rule 501 under the Securities Act of 1933)

        (a) Accredited Investor. "Accredited Investor" shall mean any person who
comes within any of the following categories, or who the issuer reasonably
believes comes within any of the following categories, at the time of the sale
of the securities to that person:

               . . .

                (3) Any organization described in Section 501 (c) (3) of the
        Internal Revenue Code, corporation, Massachusetts or similar business
        trust, or partnership, not formed for the specific purpose of acquiring
        the securities offered, with total assets in excess of $5,000,000;

                (4) Any director, executive officer, or general partner of the

        executive officer, or general partner of a general partner of that
        issuer;

                (5) Any natural person whose individual net worth, or joint net
