                             STOCK OPTION AGREEMENT

         This Stock Option Agreement, dated as of September 24, 2001 (the "Grant
Date"), is entered into by Raining Data Corporation f/k/a Omnis Technology
Corporation, a Delaware corporation (the "Company"), and Carlton Baab ("you" or
"your").

         For the following mutual undertakings and for other good and valuable
consideration, the Company and you agree as follows:

         1. Grant. The Company grants you a stock option to purchase up to One
Million (1,000,000) shares of the common stock of the Company during the term
hereof, at an option exercise price of $1.55 per share (the "Option"). The
Option shall vest ratably on a daily basis over a period of six (6) months from
the date hereof, and shall cease to vest upon your termination of employment
with the Company for any reason.

         2. Method of Exercise. You can exercise this option by providing
written notice of exercise and by paying the exercise price to the Company in
(a) cash, (b) shares of common stock of the Company having a Fair Market Value
equal to the exercise price on the exercise date (but only to the extent that
such exercise of the Option would not result in an accounting compensation
charge with respect to the shares used to pay the exercise price) or (c) payment
through a broker-dealer sale and remittance procedure pursuant to which you (i)
shall provide written instructions to a Company designated brokerage firm to
effect the immediate sale of some or all of the purchased shares and remit to
the Company, out of the sale proceeds available on the settlement date,
sufficient funds to cover the aggregate exercise price payable for the purchased
shares and (ii) shall provide written directives to the Company to deliver the
certificates for the purchased shares directly to such brokerage firm in order
to complete the sale transaction. You will be subject to reasonable limitations
on the number of requested exercises during any monthly or weekly period as
determined by the administrator of the Plan. The Company is not required to
issue fractional shares. You will have no rights as a stockholder until this
option is exercised.

         3. Option Term. The term of this option is ten (10) years from the
Grant Date and terminates for all purposes on September 23, 2011; provided
however that this option shall terminate two (2) years after the date of your
termination of employment with the Company for any reason.

         4. Transferability. This option is not transferable or assignable by
you other than upon your death by will or the laws of descent and distribution;
provided however that you may transfer this option to an inter vivos or
testamentary trust for passing to beneficiaries upon your death, or by gift to
your Immediate Family (as defined below). With these exceptions this option may
be exercised solely by you during your lifetime. All terms of the option still
apply in the event of a permitted transfer.

                                       1

         5. Plan. This option is being granted to you under the Raining Data
Corporation 1999 Stock Option Plan (the "Plan"). Defined or capitalized terms
used in this agreement and not otherwise defined herein shall have the meanings
given them in the Plan.

         6. Termination on Corporate Transaction; Acceleration; Assumption.
Notwithstanding any contrary provision hereof, effective upon the consummation
of a Corporate Transaction (as defined below), this Option shall terminate
unless the Option is assumed by the successor corporation or parent thereof in
connection with such Corporate Transaction; provided that, immediately prior to
the effective date of the Corporate Transaction, this Option shall vest as to
all then unvested shares covered by this Option. The Company shall give you
reasonable notice of a Corporate Transaction to enable you to exercise this
Option prior to the effective date of the Corporate Transaction to the extent
this Option is then exercisable in accordance with the terms of this Option
Agreement.

         7. Tax Status. This option is a Nonincentive Option. This option is not
intended to qualify as an Incentive Option within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended, and therefore you may be subject
to adverse tax consequences upon the exercise of the Option. You should consult
with your professional advisors concerning the tax effects of this option and
its exercise. On exercise of a Nonincentive Option, you will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the shares on the date of
exercise over the exercise price. If you are an employee or a former employee,
the Company may be required to withhold from your compensation or collect from
you and pay to the applicable taxing authorities an amount in cash equal to a
percentage of this compensation income at the time of exercise, and may refuse
to honor the exercise and refuse to deliver shares if such withholding amounts
are not delivered at the time of exercise. If shares obtained upon the exercise
of a Nonincentive Option are held for more than one year, any gain realized on
disposition of the shares will be treated as long-term capital gain for federal
income tax purposes and subject to tax at a maximum rate of 20%.

         8. State of Residence. You represent that you are a resident of the
State of California.

         9. Tax Withholding. You agree to satisfy all applicable foreign,
federal, state and local income and employment tax withholding obligations,
including without limitation such other tax obligations incident to the receipt
of the shares issuable upon exercise of the Option. Upon exercise of all or any
part of this option, the Company or your employer may offset or withhold (from
any amount owed by the Company or your employer to you) or collect from you or
your employer an amount sufficient to satisfy such tax obligations and/or the
employer's withholding obligations.

         10. Authority. This agreement has been duly executed and delivered by
each of us and constitutes the legally binding agreement and obligation of each
party and is enforceable in accordance with its terms.

         11. Definitions.
