APPLICABLE STATE SECURITIES LAWS, OR UNLESS EXEMPTIONS FROM SUCH REGISTRATION
AND QUALIFICATION ARE AVAILABLE.

                            RAINING DATA CORPORATION
                          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
Agreement (the "Purchase Agreement") 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"),
the terms of which are incorporated by this reference. The term "Holder" shall
initially refer to Astoria, which is the initial holder of this Warrant and
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,
$0.10 par value (the "Stock") under the terms and conditions set forth herein.
Capitalized terms used and not otherwise defined in this Common Stock Purchase
Warrant (this "Warrant") shall have the respective meanings assigned to them in
the Purchase Agreement as the same may be supplemented, modified, amended,
renewed or restated from time to time.

Section 1. Price and Exercise of Warrant.

        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").

        1.2 Warrant Price. The price per share at which the shares of Stock are
issuable upon exercise of this Warrant (the "Warrant Shares") shall be Seven
Dollars ($7.00) per share (the "Warrant Price") as adjusted hereunder.



                                       1

        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>   3

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.



                                       3
<PAGE>   4

                (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>   5

                (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>   6

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>   7

        (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>   8

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>   9

                (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>   10

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
