Gentlemen:

        This letter sets forth the agreement which has been reached concerning
the satisfaction of all of the indebtedness of General Automation, Inc., a
Delaware corporation ("GA"), to RadiSys CPD, Inc., a Delaware corporation
formerly known as Sequoia Systems, Inc. and also formerly known as Texas Micro,
Inc. ("RadiSys"), and the release by RadiSys of all other obligations owed to it
by GA in exchange for (a) a cash payment by GA to RadiSys; (b) the issuance of
two promissory notes by GA to RadiSys; and (c) the issuance of shares of GA's
common stock to RadiSys. That agreement is as follows:

        1. Payment by GA. Concurrently with the execution of this letter
agreement, GA will pay to RadiSys the amount of $1,500,000, by wire transfer to
an account designated by RadiSys (the "Cash Payment").

        2. Issuance of Promissory Notes. Concurrently with the execution of this
letter agreement, GA will execute and deliver to RadiSys two Promissory Notes,
one in the original principal amount of $250,000 in the form of Exhibit A
attached to this letter agreement (the "First Note"), and one in the original
principal amount of $500,000 in the form of Exhibit B attached to this letter
agreement (the "Second Note"). The First Note and the Second Note are at times
referred to collectively in this letter agreement as the "Notes").

        3. Issuance of Stock. GA shall issue to RadiSys 1,133,333 shares of GA's
common stock (the "Shares") as soon as is reasonably practicable after the date
of this letter agreement, but in any event within thirty (30) days after the
date of this letter agreement, GA will cause its transfer agent to issue and
deliver to RadiSys a stock certificate, standing in the name of RadiSys,
representing the Shares.

Rights Agreement pertaining to the Shares in the form of Exhibit C attached to
this letter agreement.

            (a) Satisfaction of GA's Obligations Under the Second Note. The
Second Note provides that it is due and payable in full upon the earlier to
occur of the date which is one hundred twenty (120) days following the date of
the Second Note (the "Maturity Date"); or the third business day following the
closing of a loan to GA pursuant to that certain Loan Agreement (the "Loan
Agreement") of even date herewith between GA and Pacific Mezzanine Fund LLP
("PMF"), which loan yields net proceeds to GA of not less than One Million
Dollars ($1,000,000), excluding the initial $3,150,000 loaned by PMF to the
Company pursuant to the Loan Agreement (a "Qualifying Financing"). (A copy of
the Loan Agreement is attached to this letter agreement as Exhibit D.) The
Second Note also provides, however, that in the event that a Qualifying
Financing has not been consummated on or before the Maturity Date, GA may, in
its sole discretion, elect to satisfy GA's entire obligation under the Second
Note by executing and delivering to the holder of the Second Note (the "Holder")
a Secured Convertible Promissory Note with an original principal amount equal to
the sum of the then outstanding principal balance of the Second Note and all
accrued but unpaid interest then owed on the Second Note. If GA elects to
satisfy its obligations under the Second Note in the manner referred to in the
immediately preceding sentence, it shall send written notification of that
election to the Holder (the "Notice"). Within ten (10) business days following
the Holder's receipt of the Notice:

            (b) GA shall execute and deliver to the Holder, against Holder's
execution and delivery to GA of the documents and instruments referred to in
Section 5(b) below, the following:

                (i) A Secured Convertible Promissory Note in substantially the
form of Exhibit E attached to this letter agreement (the "Secured Note"), in an
original principal amount equal to the sum of the then outstanding principal
balance of the Second Note and all accrued but unpaid interest then owed on the
Second Note (the conversion rate on which Secured Convertible Promissory Note
shall be the same as the "Conversion Rate" specified in Section 2.08 of the Loan
Agreement); and

                (ii) A Warrant in substantially the form of Exhibit F attached
to this letter agreement, covering a number of shares (rounded to the nearest
whole share) calculated by dividing the original principal amount of the Secured
Note by $8.00; and

                (iii) Such documents as may reasonably be requested by the
Holder for the purpose of making the Holder a party to the Loan Agreement as a
"Lender" thereunder (provided, however, that (A) in no event shall RadiSys
become obligated thereby to make any loan or advance to GA, other than the loan
evidenced by the Secured Note in the original principal amount specified in
Section 5(a)(i) above, and (B) notwithstanding Section 3.01(j) of the Loan
Agreement, no opinion of GA's counsel will be delivered to RadiSys in connection
with the transactions contemplated by this Section 5); and

                (iv) Such documents as may reasonably be requested by the Holder
for the purpose of making the Holder a party to, and a "Secured Party" under,
that certain Security Agreement of even date herewith entered into by PMF and
GA, a copy of which is attached to this letter agreement as Exhibit G; and

                (v) Such documents as may reasonably be requested by the Holder
for the purpose of making the Holder a party to, and an "Investor" under, that
certain Investors' Rights Agreement of even date herewith entered into by PMF
and GA, a copy of which is attached to this letter agreement as Exhibit H; and

                (vi) Such other documents and instruments (including but not
limited to amendments to the documents referred to in this Section 5(a)) as may
reasonably be requested by the Holder for the purpose of effectuating the
purposes and intent of this Section 5. (xi)

            (c) The Holder shall deliver to GA for cancellation the original of
the Second Note, and shall also execute and deliver to GA, against GA's
execution and delivery to the Holder of the documents and instruments referred
to in Section 5(a) above, the following:

                (i) A Subordination Agreement in favor of each of the Company's
Senior Lenders (as defined in the Loan Agreement), in substantially the form of
Exhibit I attached to this letter agreement; and

                (ii) An Intercreditor Agreement in substantially the form of
Exhibit J attached to this letter agreement; and

                (iii) Such other documents and instruments (including but not
limited to amendments to the documents referred to in this Section 5(b) and
Section 5(a) above) as may reasonably be requested by GA for the purpose of
effectuating the purposes and intent of this Section 5.

        5. Investment Representations of RadiSys. RadiSys understands that the
Shares will be issued to RadiSys without registration under the Securities Act
of 1933, as amended (the "Act"), and without qualification or registration under
the applicable securities laws of any state (the "State Laws") in reliance on
exemptions from such registration and qualification for non-public offerings.
RadiSys further understands that GA is relying on the representations and
warranties set forth in this letter agreement in determining that such
exemptions are available.

        6. RadiSys hereby represents and warrants to GA as follows:

            (a) Investment Intent. The acquisition of the Shares is for
investment for RadiSys' own account, not as a nominee or agent, and not with a
view to the resale or distribution of any part thereof or interest therein.
RadiSys will not offer to sell or sell the Shares or any portion thereof or
interest therein to others except in compliance with the Act and the State Laws.
The undersigned does not have any present intention of distributing or selling
any of the Shares.

            (b) Lack of Registration; Legend on Certificates. RadiSys has been
advised by GA as to the circumstances under which RadiSys is required to take
and hold the Shares, including, without limitation, the following:

                (i) The Shares have not been registered with the Securities and
Exchange Commission (the "SEC") under the Act and must be held for investment
unless subsequently registered under the Act or an exemption from registration
is available.

                (ii) Any and all certificates representing the Shares and any
and all replacements thereof shall bear and be subject to a legend in
substantially the following form affecting the transferability of the Shares:

        THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE ACT
        OF 1933 (THE "FEDERAL ACT") OR QUALIFIED UNDER THE SECURITIES LAWS OF
        ANY STATE,

<PAGE>   5

RadiSys CPD, Inc.

Page 5

        IN RELIANCE ON EXEMPTIONS FROM SUCH REGISTRATION AND QUALIFICATION FOR
        NONPUBLIC OFFERINGS. ACCORDINGLY, THE SALE, TRANSFER OR OTHER
        DISPOSITION OF SUCH SECURITIES OR ANY INTEREST THEREIN MAY NOT BE
        ACCOMPLISHED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER
        THE FEDERAL ACT AND QUALIFICATION UNDER APPLICABLE STATE SECURITIES
        LAWS, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY TO THE EFFECT
        THAT SUCH REGISTRATION AND QUALIFICATION ARE NOT REQUIRED.

            (c) Documents Reviewed by RadiSys. RadiSys has reviewed the
following documents pertaining to GA (the "GA SEC Reports"):

                (i) GA's Report on Form 10-K for the fiscal year ended September
        30, 1998, as filed with the SEC; and

                (ii) GA's Proxy Statement relating to the Annual Meeting of GA's
        shareholders held on March 25, 1999; and

                (iii) GA's Reports on Form 10-Q for the quarters ended December
        31, 1998, March 31, 1999 and June 30, 1999, as filed with the SEC; and

                (iv) GA's Reports on Form 8-K filed with the SEC on February 19,
        1999 and July 14, 1999, respectively.

that inquiries with respect to GA or the documents referred to in Section 6(c)
above may be made by RadiSys to Mr. Richard Nance, GA's Chief Financial Officer,
in writing at 17731 Mitchell North, Irvine, California 92714, or by telephone at

and has received answers from, the officers and directors of GA concerning its
operations, plans and financial condition, and has further been afforded the
opportunity to obtain any additional material necessary to verify the
information so obtained (to the extent GA possesses such material or could

            (e) No Reliance on Other Information. RadiSys has not been furnished
with any oral or written information concerning GA other than the documents
referred to in Section 6(c) above, and the information furnished or made
available to RadiSys by GAI described in Section 6(d) above, and RadiSys has
relied solely on the foregoing in connection with its decision to acquire the
Shares.

            (f) Accredited Investor. RadiSys is an "accredited investor" within
the meaning of Rule 501(a)(3) promulgated by the SEC under the Act.

        7. Representations and Warranties of GA. GA hereby represents and
warrants to RadiSys as follows:

            (a) Organization, Powers and Good Standing. GA is a corporation duly
organized, validly existing and in good standing under the laws of Delaware, and
having its principal place of business in the State of California, and has all
requisite corporate power and authority and the legal right to own and operate
its properties and to carry on its business as heretofore conducted and as
proposed to be conducted. GA is duly qualified to transact business and is in
good standing in each jurisdiction in which the failure so to qualify would have
a material adverse effect on GA. GA has all requisite power and authority to
enter into this letter agreement and to execute and deliver the Notes and to
carry out the transactions contemplated hereby and thereby.

            (b) Authorization, Binding Effect No Conflict, Etc.

                (i) All corporate action on the part of GA necessary for the
authorization, execution and delivery of this letter agreement and the Notes,
the performance of all of GA's obligations hereunder and thereunder and the
authorization, issuance and delivery of the Notes and the Shares has been taken.
This letter agreement and each of the Notes has been duly executed and delivered
by GA. This letter agreement and each of the Notes is a legal, valid and binding
obligation of GA, enforceable against it in accordance with its respective
terms, except as may be affected by bankruptcy, insolvency, reorganization,
moratorium or other similar laws or by equitable principles relating to or
limiting the rights of creditors generally.

                (ii) The execution, delivery and performance by GA of this
letter agreement and the Notes, and the consummation of the transactions
contemplated thereby (including the issuance of the Shares), do not and cannot
(A) conflict with any

<PAGE>   7

Page 7

provision of GA's Certificate of Incorporation or Bylaws, (B) conflict with,
result in a breach of, or constitute (or, with the giving of notice or lapse of
time or both, would constitute) a default under, or require the approval or
consent of any person or entity pursuant to, any material agreement, contract or
instrument to which GA is a party, or violate any provision of applicable law
binding on GA, or (C) result in the creation or imposition of any lien upon any
asset of GA.

                (iii) No governmental approval is or will be required in
connection with the execution, delivery and performance by GA of this letter
agreement or the Notes or the transactions contemplated thereby or to ensure the
legality, validity or enforceability thereof.

            (c) Financial Information Relating to GA. The financial statements
contained in the GA SEC Reports are complete and correct in all material
respects, subject to the absence of footnotes, the absence of a statement of
cash flows and normal year-end adjustments in the case of the interim financial
statements included, and have been prepared in accordance with GAAP. Without
limiting the foregoing, the financial statements contained in the GA SEC Reports
accurately set out and describe the financial condition and operating results of
GA as of the dates, and for the periods, indicated therein.

            (d) Litigation. Except as disclosed in the GA SEC Reports, there are
no actions, suits or proceedings pending or, to the best knowledge of GA,
threatened against or affecting GA, or its assets or properties before any
governmental authority (i) that, if adversely determined, could have a material
adverse effect on GA, (ii) that in any manner draw into question the validity or
the enforceability of this letter agreement or any transaction contemplated
hereby, or (iii) that might result in any change in the current equity ownership
of GA, nor, to GA's Best Knowledge, is there any basis for any matter described
in the foregoing Section 7(d), except as disclosed on Schedule 7(d) attached
hereto. There are no any actions pending or threatened (or any basis therefor
known to GA) involving the prior employment of any of GA's employees, their use
in connection with the businesses of GA of any information or techniques
allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. GA is not a party or subject to the
provisions of any order (except as imposed by laws of general application),
writ, injunction, judgment or decree (except as imposed by laws of general
application) of any court, governmental authority or government agency or
instrumentality. There is no action, suit, proceeding or investigation by GA

currently pending or which GA intends to initiate (as plaintiff), which, if
adversely determined, would be material to GA or its business or prospects.

            (e) Disclosure. GA has fully provided RadiSys with all of the
information which RadiSys has requested for deciding whether to enter into the
transactions contemplated by this letter agreement. The information in any
document, certificate or written statement furnished to RadiSys by or on behalf
of GA with respect to the business, assets, results of operation, financial
condition or prospects of GA for use in connection with the transactions
contemplated by this letter agreement is, when considered as a whole, true and
correct and does not omit to state any material fact required to be stated
therein to make the furnished information not misleading. To GA's best
knowledge, there is no fact (other than matters of a general economic nature)
that has materially and adversely affected or could reasonably be expected to
have a material adverse effect, which has not been disclosed herein, in such
other documents, certificates and statements, or the GA SEC Reports.

            (f) Valid Issuance. The outstanding shares of GA's common stock have
been duly authorized, issued and delivered and are validly outstanding, fully
paid and nonassessable. The Shares, when issued, sold and delivered pursuant to
this letter agreement, will be duly and validly issued, fully paid and
nonassessable. Assuming the accuracy of the representations of RadiSys contained
in Section 6 above, the issuance and sale of the Shares to RadiSys pursuant to
this letter agreement are exempt from the registration requirements of Section 5
of the Securities Act of 1933, as amended, (the "Securities Act") by reason of
the exemption from registration set forth in Section 4(2) of the Securities Act.

            (g) Compliance with Laws and Agreements. Except as disclosed in the
GA SEC Reports or Schedule 7(d) attached hereto, GA is not in violation or
default of any provisions of any material agreement, contract or instrument to
which it is a party or by which it is bound or of any provision of any
applicable law, which violation or default could have a material adverse effect
on GA.

            (h) PMF Consent. PMF has consented to the terms and conditions of
the Second Note, the issuance of the Secured Note in accordance with the
provisions of Section 5 above, and the other transactions contemplated by
Section 5 above.

               does not know or suspect to exist in his favor at the time of

BY RADISYS AND GA.

the Prior Warrant and the Promissory Note.

        11. Miscellaneous.
