Company with respect to its purchase of the Shares as follows:

                                       6
<PAGE>   7

        (a) Organization; Authority. The Purchaser is a limited partnership duly
organized, validly existing and in good standing under the laws of the State of
California, is duly qualified to conduct business and is in good standing under
the laws of each jurisdiction in which the nature of its business or the
ownership or leasing of its properties requires such qualification. The
Purchaser has all requisite power and authority to own and operate its
properties and assets. The execution, delivery and performance by the Purchaser
of this Agreement and the Registration Rights Agreement and all other agreements
or instruments related thereto have been duly authorized by all necessary action
on the part of the Purchaser. The Purchaser has all right, power and authority
to enter into, execute and deliver this Agreement and the Registration Rights
Agreement and to consummate the transactions contemplated hereby, and this
Agreement and said Registration Rights Agreement, once executed by the Company
and the Purchaser, will constitute the legally binding valid obligations of the
Purchaser enforceable in accordance with its terms, such enforceability being
subject only to laws of general application relating to bankruptcy, insolvency
and the relief of debtors and rules of law governing specific performance,
injunctive relief or other equitable remedies.

        (b) Accredited Investor. The Purchaser is an "accredited investor" as
that term is defined in Rule 501(a) of Regulation D of the Securities Act of
1933 ("Securities Act") (excerpts of the definition of "accredited investor" are
attached hereto and made a part hereof as Exhibit D). The principal office of
Purchaser is located in the State indicated in the space provided in the
signature page hereof.

        (c) Experience. The Purchaser, by reason of his or its business and
financial experience has such knowledge, sophistication and experience in
financial and business matters and in making investment decisions of this type
that the Purchaser is capable of (i) evaluating the merits and risks of an
investment in the Shares and making an informed investment decision, (ii)
protecting his or its own interest and (iii) bearing the economic risk of such
investment. If the Purchaser has retained a stockholder representative with
respect to the investment in the Shares, then the Purchaser shall, prior to or
at the Closing hereunder, (x) acknowledge in writing such representation and (y)
cause such representative to execute and deliver such statements or other
certificates to the Company containing such representations as are reasonably
requested by the Company.

        (d) Investment Intent. The Purchaser is acquiring the Shares for
investment for his or its own account, not as a nominee or agent and not with
the view to, or any intention of, a resale or distribution thereof, in whole or
in part, or the grant of any participation therein. The Purchaser has not been
formed for the specific purpose of acquiring the Shares.

                                       7
<PAGE>   8

        (e) Certain Restrictions. The Purchaser understands that the Shares have
not been registered under the Securities Act or state securities laws and are
being issued by reason of a specific exemption from the registration provisions
of the Securities Act and applicable state securities laws that depend upon,
among other matters, the bona fide nature of the investment intent and the
accuracy of the Purchaser's representations as expressed herein. The Purchaser
further understands that the Company shall have no obligation to register the
Shares 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 pursuant to the Registration Rights Agreement
to be entered into in connection with this Agreement. The Purchaser acknowledges
that the Shares must be held indefinitely unless subsequently registered under
the Securities Act or unless an exemption from such registration is available.
The Purchaser hereby acknowledges that because of the restrictions on transfer
or assignment of such Shares to be issued hereunder, the Purchaser may have to
bear the economic risk of the investment commitment in the Shares for an
indefinite period of time. The Purchaser further acknowledges and understands
that any investment in the Company is inherently speculative and subject to
material financial risks and that its or his entire investment in the Company
could be lost.

        (f) Compliance with Securities Laws. The Purchaser 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, in connection
with any offer, sale, pledge, transfer or other disposition of the Shares. In
furtherance of the foregoing, and in addition to the restrictions contained
herein or in the Registration Rights Agreement, the Purchaser will not offer to
sell, exchange, transfer, pledge, or otherwise dispose of any of the Shares
unless at such time at least one of the following is satisfied: (i) a
registration statement under the Securities Act covering the Shares proposed to
be sold, transferred or otherwise disposed of, describing the manner and terms
of the proposed sale, transfer or other disposition, and containing a current
prospectus, shall have been filed with the SEC and shall then be effective under
the Securities Act; (ii) such transaction shall be permitted pursuant to the
provisions of Rule 144; (iii) counsel representing the Purchaser, satisfactory
to the Company, shall have advised the Company in a written opinion letter
reasonably satisfactory to the Company and its counsel, and upon which the
Company and its counsel may rely, that no registration under the Securities Act
would be required in connection with the proposed sale, transfer or other
disposition; or (iv) an authorized representative of the SEC shall have rendered
written advice to the Purchaser (sought by the Purchaser or counsel to the
Purchaser, with a copy thereof and of all other related communications delivered
to the Company) to the effect that the SEC would take no action, or that the
staff of the SEC would not recommend that the SEC take action, with respect to
the proposed sale, transfer or other disposition if consummated. The Purchaser
is aware of the provisions of Rule 144 promulgated under the Securities Act
which permit limited resale of shares

                                       8
<PAGE>   9

purchased in a private placement subject to the satisfaction of certain
conditions, including the requirement that the Shares be held for a minimum of
one (1) year and in certain cases two (2) years, after they have been purchased
and paid for within the meaning of Rule 144.

        (g) Restrictive Legend. All certificates representing the Shares
deliverable to the Purchaser hereunder and any certificates subsequently issued
with respect thereto or in substitution therefor, unless a sale, transfer or
other disposition is executed pursuant to one or more of the alternative
conditions set forth in Section 4(f) shall have occurred, or unless the
conditions of paragraph (k) of Rule 144 promulgated under the Securities Act
shall have been satisfied, shall bear a legend substantially as follows, in
addition to any legend the Company determines in its sole judgment is required
pursuant to any applicable legal requirement:

               "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,
        SOLD, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE
        WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, AND THE
        OTHER CONDITIONS SPECIFIED IN THAT CERTAIN COMMON STOCK PURCHASE
        AGREEMENT DATED AS OF DECEMBER 4, 2000 AND THAT CERTAIN REGISTRATION
        RIGHTS AGREEMENT DATED AS OF DECEMBER 4, 2000, COPIES OF EACH OF WHICH
        RAINING DATA CORPORATION WILL FURNISH, WITHOUT CHARGE, TO THE HOLDER OF
        THIS CERTIFICATE UPON WRITTEN REQUEST THEREFOR"

The Company, at its discretion, may cause a stop transfer order to be placed
with its transfer agent(s) with respect to the certificates for the Shares but
not as to the certificates for any part of the Shares as to which said legend is
no longer appropriate when one or more of the alternatives set forth in Section
4(f) shall have been satisfied.

        (h) Access to Information. The Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that the Purchaser reasonably
considers important in making the decision to purchase the Shares. The Purchaser
has received and has reviewed the SEC Filings of the Company. The Purchaser has
had an opportunity to discuss the business, management and financial affairs and
prospects of the Company and its subsidiaries with the Company's management and
has had the opportunity to review the United States facilities of the Company
and its subsidiaries. The Purchaser acknowledges and understands that such
discussions, as well as any written information issued by the Company, were
intended to describe certain material aspects of its business and prospects but
were not intended as and were not a thorough or exhaustive description or
disclosure of the subject matter thereof.

                                       9
<PAGE>   10

        (i) Absence of Claims. The Purchaser has no knowledge of any causes of
action or other claims that could have been or in the future might be asserted
by the Purchaser against the Company or any of its predecessors, successors,
affiliates, assigns, directors, employees, agents or representatives arising out
of facts or circumstances occurring at any time on or prior to the date hereof
and in any manner relating to any duty or obligation of the Company or such
other related person or entity to the Purchaser or any affiliate.

        (j) No Conflict. The execution and delivery of the Agreement and the
consummation of the transactions contemplated hereby will not materially
conflict with any legally enforceable contract or agreement between the
Purchaser and any third person or entity; and the Purchaser is not a party to
any outstanding agreement which any material obligation or agreement is
inconsistent with this Agreement.

        (k) Full Disclosure. The representations and warranties of the Purchaser
contained in this Agreement do not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements contained herein or therein in light of the circumstances under which
they were made not misleading.

        (l) Brokers or Finders. The Purchaser has not incurred and will not
incur, as a result of any action taken by the Purchaser or its representative or
agent, any liability for brokerage or finders' fees or agents' commissions or
any similar charges in connection with this Agreement or the transactions
contemplated hereby. Purchaser agrees to fully indemnify and defend and hold
harmless the Company from and against all such liabilities incurred by Purchaser
in connection with the transactions contemplated by this Agreement, and all
costs and expenses (including reasonable fees of counsel) of investigating and
defending such claims.

        (m) Effective Dates. The representations and warranties of the Purchaser

further shall be true in all material respects on and as of the Closing as
though made at that time.

        4.     REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.

        The Purchaser hereby represents and warrants and covenants to the
Company with respect to his purchase of the Shares as follows:

        (a) Authority. The Purchaser has all right, power and authority to enter
into, execute and deliver this Agreement and the Registration Rights Agreement
and to consummate the transactions contemplated hereby, and this Agreement and
said Registration Rights Agreement, once executed by the Company and the
Purchaser, will

                                       6
<PAGE>   7

constitute the legally binding valid obligations of the Purchaser enforceable in
accordance with its terms, such enforceability being subject only to laws of
general application relating to bankruptcy, insolvency and the relief of debtors
and rules of law governing specific performance, injunctive relief or other
equitable remedies.

        (b) Accredited Investor. The Purchaser is an "accredited investor" as
that term is defined in Rule 501(a) of Regulation D of the Securities Act of
1933 ("Securities Act") (excerpts of the definition of "accredited investor" are
attached hereto and made a part hereof as Exhibit D). The Purchaser is resident
of the State indicated in the space provided in the signature page hereof.

        (c) Experience. The Purchaser, by reason of his or its business and
financial experience has such knowledge, sophistication and experience in
financial and business matters and in making investment decisions of this type
that the Purchaser is capable of (i) evaluating the merits and risks of an
investment in the Shares and making an informed investment decision, (ii)
protecting his or its own interest and (iii) bearing the economic risk of such
investment. If the Purchaser has retained a stockholder representative with
respect to the investment in the Shares, then the Purchaser shall, prior to or
at the Closing hereunder, (x) acknowledge in writing such representation and (y)
cause such representative to execute and deliver such statements or other
certificates to the Company containing such representations as are reasonably
requested by the Company.

        (d) Investment Intent. The Purchaser is acquiring the Shares for
investment for his or its own account, not as a nominee or agent and not with
the view to, or any intention of, a resale or distribution thereof, in whole or
in part, or the grant of any participation therein. The Purchaser has not been
formed for the specific purpose of acquiring the Shares.

        (e) Certain Restrictions. The Purchaser understands that the Shares have
not been registered under the Securities Act or state securities laws and are
being issued by reason of a specific exemption from the registration provisions
of the Securities Act and applicable state securities laws that depend upon,
among other matters, the bona fide nature of the investment intent and the
accuracy of the Purchaser's representations as expressed herein. The Purchaser
further understands that the Company shall have no obligation to register the
Shares 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 pursuant to the Registration Rights Agreement
to be entered into in connection with this Agreement. The Purchaser acknowledges
that the Shares must be held indefinitely unless subsequently registered under
the Securities Act or unless an exemption from such registration is available.
The Purchaser hereby acknowledges that because of the restrictions on transfer
or assignment of such Shares

                                       7
<PAGE>   8

to be issued hereunder, the Purchaser may have to bear the economic risk of the
investment commitment in the Shares for an indefinite period of time. The
Purchaser further acknowledges and understands that any investment in the
Company is inherently speculative and subject to material financial risks and
that its or his entire investment in the Company could be lost.

        (f) Compliance with Securities Laws. The Purchaser 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, in connection
with any offer, sale, pledge, transfer or other disposition of the Shares. In
furtherance of the foregoing, and in addition to the restrictions contained
herein or in the Registration Rights Agreement, the Purchaser will not offer to
sell, exchange, transfer, pledge, or otherwise dispose of any of the Shares
unless at such time at least one of the following is satisfied: (i) a
registration statement under the Securities Act covering the Shares proposed to
be sold, transferred or otherwise disposed of, describing the manner and terms
of the proposed sale, transfer or other disposition, and containing a current
prospectus, shall have been filed with the SEC and shall then be effective under
the Securities Act; (ii) such transaction shall be permitted pursuant to the
provisions of Rule 144; (iii) counsel representing the Purchaser, satisfactory
to the Company, shall have advised the Company in a written opinion letter
reasonably satisfactory to the Company and its counsel, and upon which the
Company and its counsel may rely, that no registration under the Securities Act
would be required in connection with the proposed sale, transfer or other
disposition; or (iv) an authorized representative of the SEC shall have rendered
written advice to the Purchaser (sought by the Purchaser or counsel to the
Purchaser, with a copy thereof and of all other related communications delivered
to the Company) to the effect that the SEC would take no action, or that the
staff of the SEC would not recommend that the SEC take action, with respect to
the proposed sale, transfer or other disposition if consummated. The Purchaser
is aware of the provisions of Rule 144 promulgated under the Securities Act
which permit limited resale of shares purchased in a private placement subject
to the satisfaction of certain conditions, including the requirement that the
Shares be held for a minimum of one (1) year and in certain cases two (2) years,
after they have been purchased and paid for within the meaning of Rule 144.

        (g) Restrictive Legend. All certificates representing the Shares
deliverable to the Purchaser hereunder and any certificates subsequently issued
with respect thereto or in substitution therefor, unless a sale, transfer or
other disposition is executed pursuant to one or more of the alternative
conditions set forth in Section 4(f) shall have occurred, or unless the
conditions of paragraph (k) of Rule 144 promulgated under the Securities Act
shall have been satisfied, shall bear a legend substantially as follows, in
addition to any legend the Company determines in its sole judgment is required
pursuant to any applicable legal requirement:

                                       8
<PAGE>   9

               "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,
        SOLD, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE
        WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, AND THE
        OTHER CONDITIONS SPECIFIED IN THAT CERTAIN COMMON STOCK PURCHASE
        AGREEMENT DATED AS OF DECEMBER 4, 2000 AND THAT CERTAIN REGISTRATION
        RIGHTS AGREEMENT DATED AS OF DECEMBER 4, 2000, COPIES OF EACH OF WHICH
        RAINING DATA CORPORATION WILL FURNISH, WITHOUT CHARGE, TO THE HOLDER OF
        THIS CERTIFICATE UPON WRITTEN REQUEST THEREFOR"

The Company, at its discretion, may cause a stop transfer order to be placed
with its transfer agent(s) with respect to the certificates for the Shares but
not as to the certificates for any part of the Shares as to which said legend is
no longer appropriate when one or more of the alternatives set forth in Section
4(f) shall have been satisfied.

        (h) Access to Information. The Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that the Purchaser reasonably
considers important in making the decision to purchase the Shares. The Purchaser
has received and has reviewed the SEC Filings of the Company. The Purchaser has
had an opportunity to discuss the business, management and financial affairs and
prospects of the Company and its subsidiaries with the Company's management and
has had the opportunity to review the United States facilities of the Company
and its subsidiaries. The Purchaser acknowledges and understands that such
discussions, as well as any written information issued by the Company, were
intended to describe certain material aspects of its business and prospects but
were not intended as and were not a thorough or exhaustive description or
disclosure of the subject matter thereof.

        (i) Absence of Claims. The Purchaser has no knowledge of any causes of
action or other claims that could have been or in the future might be asserted
by the Purchaser against the Company or any of its predecessors, successors,
affiliates, assigns, directors, employees, agents or representatives arising out
of facts or circumstances occurring at any time on or prior to the date hereof
and in any manner relating to any duty or obligation of the Company or such
other related person or entity to the Purchaser or any affiliate.

        (j) No Conflict. The execution and delivery of the Agreement and the
consummation of the transactions contemplated hereby will not materially
conflict with any legally enforceable contract or agreement between the
Purchaser and any third

                                       9
<PAGE>   10

person or entity; and the Purchaser is not a party to any outstanding agreement
which any material obligation or agreement is inconsistent with this Agreement.

        (k) Full Disclosure. The representations and warranties of the Purchaser
contained in this Agreement do not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements contained herein or therein in light of the circumstances under which
they were made not misleading.

        (l) Brokers or Finders. The Purchaser has not incurred and will not
incur, as a result of any action taken by the Purchaser or its representative or
agent, any liability for brokerage or finders' fees or agents' commissions or
any similar charges in connection with this Agreement or the transactions
contemplated hereby. Purchaser agrees to fully indemnify and defend and hold
harmless the Company from and against all such liabilities incurred by Purchaser
in connection with the transactions contemplated by this Agreement, and all
costs and expenses (including reasonable fees of counsel) of investigating and
defending such claims.

        (m) Effective Dates. The representations and warranties of the Purchaser
in this Agreement are true in all respects as of the date of this Agreement and
further shall be true in all material respects on and as of the Closing as
though made at that time.

        5. PURCHASER'S CONDITIONS TO CLOSING. The obligation of the Purchaser to
