                       STOCK PLEDGE AND SECURITY AGREEMENT

      THIS STOCK PLEDGE AND SECURITY AGREEMENT is made this 30th day of
September, 1999 by and between General Automation, Inc. ("Pledgor"), Comerica
Bank-California ("Bank"), and Pacific Mezzanine Fund, L.P. ("PMF" or "Pledge
Holder").

                                    RECITALS

            A.    Bank has entered into a Loan and Security Agreement dated
December 18, 1997, as amended from time to time (the "Bank Loan Agreement"),
with Pledgor, as borrower ("Borrower"). All capitalized terms used herein
without definition have the meanings ascribed to them in the Bank Loan
Agreement.

            B.    PMF has entered into a Loan Agreement dated September __, 1999
(the "PMF Loan Agreement"), with Pledgor, as borrower.

            C.    Pledgor is the record and beneficial owner of ___% of the
outstanding shares of the Common Stock of Liberty ________, a ___________
corporation (the "Stock"), as more particularly described in Exhibit A hereto,
together with all proceeds and substitutions of any thereof, all interest paid
thereon, and all other cash and noncash proceeds of the foregoing (the "Pledged
Collateral").

            D.    Bank has required as a condition of entering into the Second
Amendment to the Bank Loan Agreement that Pledgor deliver this Pledge Agreement
to secure the obligations of Borrower under the Bank Loan Agreement. PMF has
required as a condition of entering into the PMF Loan Agreement that Pledgor
deliver this Pledge Agreement to secure the obligations of Borrower under the
PMF Loan Agreement.

      NOW, THEREFORE, Pledgor, Bank and PMF agree as follows:

      1.    Pledge of Collateral. Pledgor hereby pledges to Bank and grants to
Bank a security interest in the Pledged Collateral, as security for the prompt
performance of all of Borrower's obligations under the Loan Agreement (the "Bank
Obligations"). Pledgor also hereby pledges to PMF and grants to PMF a security
interest in the Pledged Collateral, junior and subordinate to Bank's interest,
as security for the prompt performance of all of Borrower's obligations under
the PMF Loan Agreement (the "PMF Obligations").

      2.    Delivery, Holding and Rights to Pledged Collateral. Any certificate
or certificates for the securities included in the Pledged Collateral,
accompanied by an instrument of assignment duly executed in blank by Pledgor,
have been, or will be immediately upon the subsequent receipt thereof by
Pledgor, delivered by Pledgor to Pledge Holder, and Pledge Holder hereby
acknowledges receipt of the Pledged Collateral and endorsed assignment
instrument. Pledge Holder shall hold the Pledged Collateral first for the
benefit of Bank as security for repayment of the Bank Obligations, and second
for the benefit of PMF as security for repayment of the PMF Obligations. PMF
agrees that its interest in the Pledged Collateral is junior to the interest of
the Bank in the Pledged Collateral.

      3.    Representations, Warranties and Covenants. Pledgor represents and
warrants to and covenants with Bank and PMF that:

            3.1   The Pledged Collateral is owned by Pledgor free and clear of
any security interests, liens, encumbrances, options or other restrictions
created by Pledgor, senior in interest or priority to that granted Bank hereby;

            3.2   Pledgor has full power and authority to create a first lien on
the Pledged Collateral in favor of Bank and a second lien on the Pledged
Collateral in favor of PMF and no disability or contractual obligation exists
that would prohibit Pledgor from pledging the Pledged Collateral pursuant to
this Agreement, and Pledgor will not

                                       1
<PAGE>   2

assign, create or permit to exist any other claim to, lien or encumbrance upon,
or security interest in any of the Pledged Collateral senior to the first
priority security interest granted to Bank and the second priority security
interest granted to PMF hereby; and

            3.3   The Pledged Collateral is not the subject of any present or
threatened suit, action, arbitration, administrative or other proceeding, and
Pledgor knows of no reasonable grounds for the institution of any such
proceedings.

      4.    Release of Pledged Collateral. Upon (a) receipt of notice from Bank
that Pledgor has satisfied in full the Bank Obligations and (b) Borrower's
satisfaction in full the PMF Obligations, Pledge Holder shall release the
Pledged Shares to Pledgor and Pledge Holder shall have no further duties or
obligations hereunder.

      5.    Event of Default as to Bank. Each of the following shall constitute
an event of default by Pledgor as to Bank ("Bank Event of Default") hereunder:

            5.1   The occurrence of an Event of Default under the Bank Loan
Agreement; or

            5.2   The breach of any provision of this Agreement by Pledgor or
the failure by Pledgor to observe or perform any of the provisions of this
Agreement.

      6.    Bank's Remedies Upon a Bank Event of Default. Upon the occurrence of
a Bank Event of Default, Bank shall have the right to exercise all such rights
as a secured party under the California Uniform Commercial Code as it, in its
sole judgment, shall deem necessary or appropriate, including the right to
liquidate the Pledged Collateral and apply the proceeds thereof to reduce the
principal amount outstanding under the Bank Loan Agreement. After the disposal
of any of the Pledged Collateral, Bank may deduct all reasonable legal and other
expenses and attorney's fees for protecting its interest and enforcing its
remedies under the Bank Loan Agreement and this Agreement and shall apply the
residue of the proceeds to, or hold as a reserve against, the Bank Obligations
in such manner as Bank in its reasonable discretion shall determine, and shall
pay the balance, if any to Pledgor.

      7.    Event of Default as to PMF. Termination of the Standstill Period,
defined in and provided for in paragraph 3 of the Subordination Agreement dated
September __, 1999 between Bank and PMF, along with one of the following events,
shall constitute an event of default by Pledgor as to PMF ("PMF Event of
Default") hereunder:

            (a)   The occurrence of an Event of Default under the PMF Loan
Agreement; or

            (b)   The breach of any provision of this Agreement by Pledgor or
the failure by Pledgor to observe or perform any of the provisions of this
Agreement.

      8.    PMF's Remedies Upon a PMF Event of Default. Upon the occurrence of a
PMF Event of Default and five business days after written notice to Bank, PMF
shall have the right to exercise all such rights as a secured party under the
California Uniform Commercial Code as it, in its sole judgment, shall deem
necessary or appropriate, including the right to liquidate the Pledged
Collateral and apply the proceeds thereof to reduce the principal amount
outstanding under the PMF Loan Agreement. After the disposal of any of the
Pledged Collateral, PMF may deduct all reasonable legal and other expenses and
attorney's fees for protecting its interest and enforcing its remedies under the
PMF Loan Agreement and this Agreement and shall apply the residue of the
proceeds to, or hold as a reserve against, the PMF Obligations in such manner as
PMF in its reasonable discretion shall determine, and shall pay the balance, if
any to Pledgor.

      9.    Amendment of Loan Documents. Pledgor authorizes Bank, without notice
or demand and without affecting its liability hereunder, from time to time to
(a) renew, extend, or otherwise change the terms of the Guaranty or the Loan
Documents or any part thereof; (b) take and hold security for the payment of the
Obligations, and exchange, enforce, waive and release any such security; and (c)
apply such security and direct the order or manner of sale thereof as Bank in
its sole discretion may determine.

      10.   Pledgor Waivers. Pledgor waives any right to require Bank to (a)
proceed against Borrower, any Guarantor or any other person; (b) proceed against
or exhaust any security held from Borrower or any Guarantor; (c) marshal any
assets of Borrower or any Guarantor; or (d) pursue any other remedy in Bank's
power whatsoever. Bank may, at its election, exercise or decline or fail to
exercise any right or remedy it may have against Borrower or any security held
by Bank, including without limitation the right to foreclose upon any such
security by judicial or nonjudicial sale, without affecting or impairing in any
way the liability of Pledgor hereunder. Pledgor waives any defense arising by
reason of any disability or other defense of Borrower or by reason of the
cessation from any cause whatsoever of the liability of Borrower. Pledgor waives
any setoff, defense or counterclaim that Borrower may have against Bank. Pledgor
waives any defense arising out of the absence, impairment or loss of any right
of reimbursement or subrogation or any other rights against Borrower. Until all
of the Obligations Borrower owes to Bank have been paid in full, Pledgor shall
have no right of subrogation or reimbursement, contribution or other rights
against Borrower, and Pledgor waives any right to enforce any remedy that Bank
now has or may hereafter have against Borrower. Pledgor waives all rights to
participate in any security now or hereafter held by Bank. Pledgor waives all
presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor, and notices of acceptance of this
Agreement and of the existence, creation, or incurring of new or additional
indebtedness. Pledgor assumes the responsibility for being and keeping itself
informed of the financial condition of Borrower and of all other circumstances
bearing upon the risk of nonpayment of any indebtedness or nonperformance of any
obligation of Borrower, warrants to Bank that it will keep so informed, and
agrees that absent a request for particular information by Pledgor, Bank shall
have no duty to advise Pledgor of information known to Bank regarding such
condition or any such circumstances. Pledgor waives the benefits of California
Civil Code sections 2809, 2810, 2819, 2845, 2847, 2848, 2849, 2850, 2899 and
3433.

      11.   Obligations of Pledge Holder.

            11.1  Determination of Bank Event of Default. Pledge Holder shall
have no duty or right to determine the existence of a Bank Event of Default, but
may, without any liability whatsoever, rely upon the written notice of Bank that
such default has occurred.

            11.2  Notice to Pledge Holder. Unless otherwise provided for in this
Pledge Agreement, no notice, demand or change of instructions of any kind to
Pledge Holder shall be effective unless in writing, signed by both Pledgor and
Bank, and consented to by Pledge Holder in writing.

            11.3  Bankruptcy of a Party. Bankruptcy, insolvency, dissolution, or
absence of any party hereto shall not affect performance on the part of the
Pledge Holder.

            11.4  Duties of Pledge Holder. Pledge Holder shall carry out its
duties under this Pledge Agreement to the best of its ability and in recognition
of the priorities to the Pledged Collateral as set forth in paragraph 2 hereof.

            11.5  Deposit of Pledged Shares in Court. In case any demand is made
by Pledgor, Bank or Pledge Holder, or any of them, which is not assented to by
the other of said parties and which said party has no right to make independent
of the other, Pledge Holder may at its option be relieved from all liability to
either Pledgor or Bank by depositing all of the Pledged Collateral in its
possession or control with the Superior Court for the City and County of Santa
Clara, for the purpose of permitting the Pledgor, Bank and PMF to litigate their
respective rights in said court. The receipt by the Clerk of said court (whether
or not said deposit is made pursuant to court order) shall discharge Pledge
Holder from all liability to Pledgor or Bank, and the same may be pleaded as a
bar to any action against Pledge Holder.

      12.   Indemnity of Pledge Holder. Pledgor shall indemnify and hold Pledge
Holder harmless from all costs, expenses, damages, losses, attorneys' fees,
liabilities, and judgments which Pledge Holder may incur or suffer by reason of
performance of this Pledge Agreement. In the event of any litigation in respect
of this Pledge Agreement, or in the event Pledge Holder commences an
interpleader action, Pledgor promises to pay and reimburse Pledge Holder for all
costs, expenses, damages, losses, attorneys' fees, liabilities, or judgments
which may be incurred or suffered by Pledge Holder.

Grantor has made or filed in respect of any patents, copyrights or trademarks
and the status of any outstanding applications or registrations. Grantor shall
promptly advise Secured Party of any material change in the composition of the
Collateral, including but not limited to any subsequent ownership right of the
Grantor in or to any Trademark, Patent or Copyright not specified in this
Agreement;

            (f) Grantor shall (i) protect, defend and maintain the validity and
enforceability of the Trademarks, Patents and Copyrights (ii) use its best
efforts to detect infringements of the Trademarks, Patents and Copyrights and
promptly advise Secured Party in writing of material infringements detected and
(iii) not allow any Trademarks, Patents or Copyrights to be abandoned, forfeited
or dedicated to the public without the written consent of Secured Party, which
shall not be unreasonably withheld, unless Grantor determines that reasonable
business practices suggest that abandonment is appropriate;

            (g) Grantor shall register or cause to be registered (to the extent
not already registered) with the United States Patent and Trademark Office or
the United States Copyright Office, as applicable, those intellectual property
rights listed on Exhibits A, B and C hereto within thirty (30) days of the date
of this Agreement. Grantor shall register or cause to be registered with the
United States Patent and Trademark Office or the United States Copyright Office,
as applicable, those additional intellectual property rights developed or
acquired by Grantor from time to time in connection with any product prior to
the sale or licensing of such product to any third party (including without
limitation revisions or additions to the intellectual property rights listed on
such Exhibits A, B and C). Grantor shall, from time to time, execute and file
such other instruments, and take such further actions as Secured Party may
reasonably request from time to time to perfect or continue the perfection of
Secured Party's interest in the Collateral;

            (h) This Agreement creates, and in the case of after acquired
Collateral, this Agreement will create at the time Grantor first has rights in
such after acquired Collateral, in favor of Secured Party a valid and

                                       2

perfected first priority security interest in the Collateral in the United
States securing the payment and performance of the obligations evidenced by the
Loan Documents upon making the filings referred to in clause (i) below;

            (i) To its knowledge, except for, and upon, the filing with the
United States Patent and Trademark office with respect to the Patents and
Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests created hereunder, and except as has
been already made or obtained, no authorization, approval or other action by,
and no notice to or filing with, any U.S. governmental authority or U.S.
regulatory body is required either (i) for the grant by Grantor of the security
interest granted hereby or for the execution, delivery or performance of this
Agreement by Grantor in the U.S. or (ii) for the perfection in the United States
or the exercise by Secured Party of its rights and remedies hereunder;

            (j) All information heretofore, herein or hereafter supplied to
Secured Party by or on behalf of Grantor with respect to the Collateral is
accurate and complete in all material respects;

            (k) Grantor shall not enter into any agreement that would materially
impair or conflict with Grantor's obligations hereunder without Secured Party's
prior written consent, which consent shall not be unreasonably withheld. Grantor
shall not permit the inclusion in any material contract to which it becomes a
party of any provisions that could or might in any way prevent the creation of a
security interest in Grantor's rights and interests in any property included
within the definition of the Collateral acquired under such contracts; and

            (l) Upon any executive officer of Grantor obtaining actual knowledge
thereof, Grantor will promptly notify Secured Party in writing of any event that
materially adversely affects the value of any Collateral, the ability of Grantor
to dispose of any Collateral or the rights and remedies of Secured Party in
relation thereto, including the levy of any legal process against any of the
Collateral.

        4. Secured Party's Rights. Secured Party shall have the right, but not
the obligation, to take, at Grantor's sole expense, any actions that Grantor is
required under this Agreement to take but which Grantor fails to take, after
fifteen (15) days' notice to Grantor. Grantor shall reimburse and indemnify
Secured Party for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this section 4.

        5. Inspection Rights. Grantor hereby grants to Secured Party and its
employees, representatives and agents the right to visit, during reasonable
hours upon prior reasonable written notice to Grantor, any of Grantor's plants
and facilities that manufacture, install or store products (or that have done so
during the prior six-month period) that are sold utilizing any of the
Collateral, and to inspect the products and quality control records relating
thereto upon reasonable written notice to Grantor and as often as may be
reasonably requested.

        6. Further Assurances; Attorney in Fact.

            (a) On a continuing basis, Grantor will make, execute, acknowledge
and deliver, and file and record in the proper filing and recording places in
the United States, all such instruments, including appropriate financing and
continuation statements and collateral agreements and filings with the United
States Patent and Trademark Office and the Register of Copyrights, and take all
such action as may reasonably be deemed necessary or advisable, or as requested
by Secured Party, to perfect Secured Party's security interest in all
Copyrights, Patents and Trademarks and otherwise to carry out the intent and
purposes of this Agreement, or for assuring and confirming to Secured Party the
grant or perfection of a security interest in all Collateral.

            (b) Grantor hereby irrevocably appoints Secured Party as Grantor's
attorney-in-fact, with full authority in the place and stead of Grantor and in
the name of Grantor, from time to time in Secured Party's discretion, to take
any action and to execute any instrument which Secured Party may deem necessary
or advisable to accomplish the purposes of this Agreement, including (i) to
modify, in its sole discretion, this Agreement without first obtaining Grantor's
approval of or signature to such modification by amending Exhibit A, Exhibit B
and Exhibit C, thereof, as appropriate, to include reference to any right, title
or interest in any Copyrights, Patents or Trademarks acquired by Grantor after
the execution hereof or to delete any reference to any right, title or interest
in any Copyrights, Patents or Trademarks in which Grantor no longer has or
claims any right, title or interest, (ii) to file, in its sole discretion, one
or more financing or continuation statements and amendments thereto, relative to
any of the Collateral without the signature of Grantor where permitted by law
and (iii) after the occurrence of an Event of Default, to transfer the
Collateral into the name of Bank or a third party to the extent permitted under
the California Uniform Commercial Code.

                                       3

        7. Events of Default. The occurrence of any of the following shall
constitute an Event of Default under the Agreement:

            (a) An Event of Default occurs under the Loan Documents; or

            (b) Grantor breaches any warranty or agreement made by Grantor in
this Agreement and, as to any breach that is capable of cure, Grantor fails to
cure such breach within five (5) days of the occurrence of such breach.

        8. Remedies. Upon the occurrence and continuance of an Event of Default,
Secured Party shall have the right to exercise all the remedies of a secured
party under the California Uniform Commercial Code, including without limitation
the right to require Grantor to assemble the Collateral and any tangible
property in which Secured Party has a security interest and to make it available
to Secured Party at a place designated by Secured Party. Secured Party shall
have a nonexclusive, royalty free license to use the Copyrights, Patents and
Trademarks to the extent reasonably necessary to permit Secured Party to
exercise its rights and remedies upon the occurrence of an Event of Default.
Grantor will pay any expenses (including reasonable attorneys' fees) incurred by
Secured Party in connection with the exercise of any of Secured Party's rights
hereunder, including without limitation any expense incurred in disposing of the
Collateral. All of Secured Party's rights and remedies with respect to the
Collateral shall be cumulative.

        9. Indemnity. Grantor agrees to defend, indemnify and hold harmless
Secured Party and its officers, employees, and agents against: (a) all
obligations, demands, claims, and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Agreement, and
(b) all losses or expenses in any way suffered, incurred, or paid by Secured
Party as a result of or in any way arising out of, following or consequential to
transactions between Secured Party and Grantor, whether under this Agreement or
otherwise (including without limitation reasonable attorneys' fees and
reasonable expenses), except for losses arising from or out of Secured Party's
gross negligence or willful misconduct.

        10. Course of Dealing. No course of dealing, nor any failure to
exercise, nor any delay in exercising any right, power or privilege hereunder
shall operate as a waiver thereof.

        11. Attorneys' Fees. If any action relating to this Agreement is brought
by either party hereto against the other party, the prevailing party shall be
entitled to recover reasonable attorneys' fees, costs and disbursements.

        12. Amendments. This Agreement may be amended only by a written
instrument signed by both parties hereto.

        13. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute the same instrument.

        14. California Law and Jurisdiction; Jury Waiver. This Agreement shall
be governed by the laws of the State of California, without regard for choice of
law provisions. Grantor and Secured Party consent to the exclusive jurisdiction
of any state or federal court located in Santa Clara County, California. GRANTOR
AND SECURED PARTY EACH WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THE LOAN DOCUMENTS, THIS
AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING CONTRACT
CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR
STATUTORY CLAIMS.
