                         BURLINGAME, CALIFORNIA 94010
Dear Shareholder of
Sequoia Computer Corporation:

    
     You are cordially invited to a Special Meeting of the Shareholders (the
"Meeting") of Sequoia Computer Corporation, a California corporation (the
"Company" or "Sequoia"), at which you will be asked to vote upon a merger (the
"Merger") of SCC Acquisition Corp. ("SAC"), a wholly-owned subsidiary of TMS,
Inc. ("TMS"), with and into the Company.  If the Merger is approved and
consummated, you will be entitled to receive 2.837 shares of TMS Common Stock,
$.05 par value ("TMS Common Stock"), for each share of Common Stock of the
Company that you own.     
    
     TMS Common Stock is traded on the over-the-counter market, and is not 
currently eligible for listing on the Nasdaq-NMS, Nasdaq Small Cap Market or 
any exchange.  TMS Common Stock is considered to be a "penny stock" under the 
rules of the Securities and Exchange Commission.  See "Risk Factors."     
    
     Enclosed are a Notice of Special Meeting of Shareholders and a Proxy
Statement - Prospectus for the Meeting to be held at 10:00 a.m., P.S.T., on
March 15, 1996, at the Company's office located at 433 Airport Boulevard, Suite
414, Burlingame, California.     
    
     The Board of Directors has carefully reviewed and considered the terms and
conditions of the Amended Plan of Reorganization and Agreement of Merger (the
"Merger Agreement") pertaining to the Merger. On the basis of all factors which
it deemed relevant, the Board of Directors has concluded that the Merger
Agreement and the Merger contemplated thereby are fair to and in the best
interests of the Company's shareholders. The terms of the Merger, as well as
other important information, are contained in the enclosed Proxy Statement -
Prospectus. Also being delivered herewith in connection with the Merger is the
TMS Annual Report to Shareholders for the year ended August 31, 1995, and the
TMS Notice of Annual Meeting and Proxy Statement for the 1995 Annual Meeting of
Shareholders. You are urged to read the Proxy Statement - Prospectus and the
accompanying documents carefully.     

     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT YOU VOTE FOR THE MERGER.

    
     
    
     Shareholders who do not vote to approve and adopt the Merger Agreement and
who properly exercise dissenters' rights of appraisal with respect to their
shares, and otherwise comply with the provisions of Section 1300  et seq., of
the California Corporations Code, will be entitled, if the Merger is
consummated, to seek appraisal of the "fair value" of their shares instead of
receiving shares of TMS Common Stock.  Such provisions of the California
Corporations Code are appended as Exhibit II to the Proxy Statement - Prospectus
which accompanies this letter.     
    
     Under California law, the Merger may not be consummated unless approved by
the holders of at least a majority of all outstanding shares of Common Stock. I
have agreed in the Merger Agreement to vote all of my shares in favor of the
approval of the Merger Agreement, and approval of the Merger Agreement is
thereby assured.     
        
     Even though approval of the Merger is assured, your vote is nonetheless
important. If you do not vote in person at the Meeting or vote by proxy, the
Company must wait up to 30 days to determine whether you are dissenting to the
Merger. The Merger cannot be completed until the extent of dissenters' shares is
known. Therefore, if you do not intend to dissent to the Merger, the Board
believes that your vote is still necessary to complete the Merger at the
earliest opportunity.     
    
     Thank you for your continued support of Sequoia.      

                                   Very truly yours,

                                   Dana R. Allen
                                   Chairman of the Board
                                   of Directors

                                     the California Corporations Code) will be converted into 2.837 shares of
                                     common stock, $.05 par value, of TMS (the "TMS Common Stock").

                                     fair to the shareholders of the Company and recommended adoption of
                                     the Merger Agreement by the shareholders.  See "Background of the
                                     Merger."
 
Effective Date                       Subject to the terms and conditions of the Merger Agreement, the
   of the Merger:                    Merger will become effective (the "Effective Date") upon the filing of
                                     certain documents with the Secretary of State of Oklahoma and the
                                     Secretary of State of California.  The Effective Date is currently
                                     expected to be the date of the Meeting.
 
Conversion of Sequoia Stock;         Each share of Sequoia Stock outstanding at the Effective Date (other
   Exchange of Certificates:         than shares held of record by Dissenting Shareholders) will be converted
                                     into the right to receive 2.837 shares of TMS Common Stock.

Tax Consequences                     The Merger is intended to qualify as a tax-free reorganization within the
   to Shareholders:                  meaning of Section 368(a) of the Internal Revenue Code of 1986, as
                                     amended (the "Code").  Due to the individual nature of tax
                                     consequences, each shareholder is urged to consult his own tax advisor
                                     with respect to the tax consequences to him of the Merger, including the
                                     effects of state, local, foreign and other tax laws.  See "Certain Federal
                                     Income Tax Consequences of the Merger."

                                     was the day before first announcement of the terms of the Merger)
                                     judicially appraised and paid to them in cash.  Such shareholders must:
                                     (i) vote against the Merger or abstain from voting for the Merger; (ii)

                              shareholder is required to include a claim setting
                              forth his or her opinion of the fair market value
                              of the shares with the shareholder's demand to
                              exercise his or her dissenters rights; (ii) the
                              claim by the dissenting shareholder represents an
                              offer to sell the shares by the dissenting
                              shareholder to Sequoia; (iii) Sequoia may accept
                              the offer to purchase the shares, with interest at
                              the legal rate, within thirty (30) days after the
                              approval of the Merger Agreement, or the Effective
                              Date of the Merger; (iv) if the dissenting
                              shareholder and Sequoia are unable to agree upon
                              the fair market value of the shares, then either
                              party may, within six months after the approval
                              date, seek a court determination of appraisal of
                              the fair market value of the shares. The
                              procedures for determining the fair market value
                              of dissenting shareholder's shares, as well as the
                              right of judicial appraisal of the fair market
                              value of such shares is set forth in the Section
                              entitled "Rights of Dissenting Shareholders."    
    
                              Statutory Compliance Necessary.  The full text of
                              the Corporations Code is attached to this Proxy
                              Statement - Prospectus as Exhibit II. Any
                              deviation from the statutory requirements may
                              result in a termination of dissenters' appraisal
                              rights. See "Rights of Dissenting
                              Shareholders."    
    
                              Effect of Substantial Amounts of Dissenting
                              Shares. For several reasons, a substantial amount
                              of dissenting shares would, even though
                              insufficient to disapprove the Merger Agreement,
                              make consummation of the Merger unlikely. First,
                              is a condition for closing of the Merger by SAC
                              and TMS that there be no more than 15,000
                              dissenting shares of Sequoia Stock. Second, a
                              substantial amount of dissenting shares would
                              prohibit pooling-of-interests accounting treatment
                              for the Merger, which would be undesirable to both
                              TMS and Sequoia. Therefore, it is unlikely that
                              there will be a closing of the Merger if there is
                              a substantial amount of dissenting shares.
                              Nevertheless, in the event the level of dissenting
                              shares are of such a magnitude as to prohibit
                              pooling-of-interests accounting treatment, Sequoia
                              shareholders would receive an amended Proxy
                              Statement - Prospectus describing the resulting
                              accounting treatment and the effect of known
                              dissenting shares.

                                  RISK FACTORS

     In addition to the other information in this Proxy Statement - Prospectus,
the following risk factors should be considered carefully in evaluating TMS, its
business and the Merger.

     Variability of Quarterly Operating Results.  TMS revenues and operating
results can vary substantially from quarter to quarter.  License revenues, which
represented approximately 55% of total revenues in fiscal 1995, are difficult to
forecast because of factors such as the size and timing of individual license
transactions, changes in customer budgets and deployments of units incorporating
TMS software, and general economic conditions.  In recent years, TMS has
emphasized software development services as a means of mitigating the
variability of revenues and operating results, and the principal growth in TMS
revenues has been in the area of services.  Although TMS currently has a backlog
of software development services and document conversion services, there is no
assurance that TMS will be able to maintain that backlog.

     Competition and Market Trends.  The computer software market is highly
competitive.  As the markets in which TMS products and services are sold
continue to develop and as TMS enters new markets, TMS expects that additional
competitors will enter those markets and that competition will become more
intense.  Some of the competitors or potential competitors of TMS have greater
financial, marketing, or technical resources than TMS.  These competitors may be
able to adapt more quickly to new or emerging technologies and standards or
changes in customer requirements or may be able to devote greater resources to
the promotion and sale of their products than TMS.  Many of these competitors
market, or can potentially market, their products directly to the ultimate
consumers of such products and may have more ability to control pricing and
marketing decisions which may affect their revenues.  There can be no assurance
that TMS will be able to continue competing successfully in this industry.
Continued investment in research and product development and in marketing will
be required to permit TMS to compete successfully, and there is no assurance
that TMS will have the necessary capital resources to fund that investment.     

     Possible Volatility of Stock Price.  Trading of TMS Common Stock has been
limited; however, if trading becomes more active, the trading price in the
future could be subject to wide fluctuations in response to quarterly variations
in operating results, announcements of technological innovations or new products
by TMS or its competitors, as well as other events or factors.  In addition, the
stock market has from time to time experienced extreme price and volume
fluctuations which have particularly affected the stock price of many high
technology companies and which often have been unrelated to the operating
performance of these companies.  These broad market fluctuations may adversely
affect the market price of TMS Common Stock.     
    
     No Current Listing on Stock Exchange; Effect of "Penny Stock" Status. TMS
Common Stock is traded on the over-the-counter market and is not currently
eligible for inclusion on the Nasdaq Small Cap Market or any other stock
exchange and eligibility for such inclusion following completion of the Merger
is subject to compliance with several requirements, such as a minimum market
price of TMS Common Stock. Moreover, the Company's Common Stock is considered to
be a "penny stock" under the rules of the Commission. Trading in penny stocks
tends to be limited because broker-dealers must comply with special procedures,
disclosures and practices. To qualify for listing on the Nasdaq Small Cap Market
and also to be elevated from penny stock status, TMS must meet certain
requirements which it does not currently meet, particularly that the market
price of TMS Common Stock exceed $3.00 per share. To satisfy this requirement,
it may be necessary to effect a reverse stock split.    
                                      10
<PAGE>
 
    
There is no assurance that a reverse split will be successful in reaching such a
minimum price or that the price of TMS Common Stock would, after adjustment for
the reverse split, trade at the same level as the pre-split shares. TMS has,
from time to time, considered a reverse split and may effect a reverse split in
the future; however, there are no present commitments to do so. In any event,
even if an exchange listing is obtained, there can be no assurance that the
market for TMS Common Stock will become liquid or active or that liquidity or
activity, if achieved, will be sustained. See "Background of the Merger - 
Considerations Regarding the Market for TMS Common Stock."      
    
     Dependence Upon a Single Customer.  During fiscal 1995, one customer,
POWERCOM, accounted for approximately 27% of TMS' total revenue; however,
revenue from such customer is expected to decline in fiscal 1996.  For the first
quarter of fiscal 1996, another customer, Toro, accounted for 15% of total
revenue in that quarter and revenues for that customer are expected to decline
in the third quarter of fiscal 1996.  Although TMS has probable new contracts
with other customers that could replace the decline in revenues associated with
POWERCOM and Toro, there can be no assurance that the efforts of TMS to replace
such revenues will be successful, and the extent to which such revenues are not
replaced could have a material adverse effect on the revenues and net income of
TMS.     

    
     Risks of Software Product Development. The future success of TMS will
depend on its ability to develop and release, on a timely basis, new software
products and upgrades. TMS has historically engaged in software development
services for customers and it derives revenues from such services and licensing
revenue from the customer's future use of the software developed by TMS. The
software development process is inherently unpredictable. Development time and
the achievability of design objectives may not be determinable until very late
in the development process. Problems and delays in product development may
result in the delay or cancellation of planned product or service offerings by
TMS and its strategic partners, and such problems and delays could have an
adverse effect on the operating results of TMS. Consequently, the receipt of
service and licensing revenue from these customers will also be delayed. There
can be no assurance that TMS will not experience similar problems and delays in
the future, resulting in material adverse effects on TMS operating results.
Furthermore, no complex software product is totally free of errors, and
significant errors may go undetected for some time. Discovery of significant
errors may delay or cancel product releases and, if not discovered until after
product release, may necessitate recall of products by TMS and its strategic
partners and expose TMS to substantial expense and claims for 
reimbursement.     


     Dependence on Key Personnel.  TMS believes that its continued success will
depend in large part upon its ability to attract and retain highly-skilled
technical, managerial and marketing personnel.  Competition for such personnel
in the software industry is intense, and TMS has from time to time experienced
difficulty in locating candidates with appropriate qualifications.  There can be
no assurance that TMS will be successful in attracting and retaining the
personnel it requires to develop and market new and enhanced products and
conduct its operations successfully.

    
     Dependence on Proprietary Technology.  TMS relies on a combination of trade
secret, copyright and trademark laws, nondisclosure agreements and other
contractual provisions and technical measures to protect its proprietary rights.
There can be no assurance that these protections will be adequate or that the
competitors of TMS will not independently develop technologies that are
substantially equivalent or superior to the technology of TMS.  TMS makes source
code available to certain of its customers and this may increase the likelihood
of misappropriation or other misuse of the intellectual property of TMS.
Furthermore, TMS has no patents, and existing copyright laws afford only limited
protection.  In addition, the laws of certain countries in which the products of
TMS are or may be licensed do not protect its products and intellectual property
rights to the same extent as the laws of the United States.  There can be no
assurance that a third party will not assert that the technology of TMS violates
its patents in the future.  As the number of software products in the industry
increases and the functionality of these products      

                                       11
<PAGE>
 
further overlap, TMS believes that software developers may become increasingly
subject to infringement claims. Any such claims, with or without merit, can be
time consuming and expensive to defend.

    
     Potential Issuance of Preferred Stock; Anti-Takeover Provisions.  The Board
of Directors of TMS has the authority to issue up to 1,000,000 shares of
Preferred Stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of these shares without any further vote or action by
the shareholders.  The rights of the holders of TMS Common Stock will be subject
to, and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future.  The issuance of the Preferred Stock,
while providing desirable flexibility in connection with possible acquisitions
and other corporate purposes, could have the effect of making it more difficult
for a third party to acquire a majority of the outstanding voting stock of TMS,
thereby delaying, deferring or preventing a change in control of TMS.
Furthermore, such Preferred Stock may have other rights, including economic
rights, senior to the TMS Common Stock, and as a result, the issuance of such
stock could have a material adverse effect on the market value of the TMS Common
Stock.  TMS has no present plans to issue shares of Preferred Stock.  TMS may in
the future adopt other measures that may have the effect of delaying, deferring
or preventing a change in control of TMS.  Certain of such measures may be
adopted without any further vote or action by the shareholders.  TMS has no
present plans to adopt any such measures.  TMS is also afforded the protection
of Section 1145 of the Oklahoma General Corporation Act, which could delay or
prevent a change in control of TMS, impede a merger, consolidation or other
business combination involving TMS or discourage a potential acquiror from
making a tender offer or otherwise attempting to obtain control of TMS.     

     No Dividends on TMS Stock. TMS has never paid a cash dividend on TMS Common
Stock and TMS does not currently intend to pay cash dividends on TMS Common
Stock in the foreseeable future.

    
     Voting Power of Officers and Directors.  Subsequent to the Merger, the
officers and directors of TMS, inclusive of Dana R. Allen, Chairman, President
and Chief Executive Officer of Sequoia, will retain voting power of
approximately 32.1% of the issued and outstanding shares of TMS Common Stock and
therefore will be able exert a significant degree of influence in the election
of the Board of Directors and the control over the affairs of TMS.     

    
     Future Acquisitions.  TMS may in the future pursue acquisitions of
complementary products, technologies and businesses. Future acquisitions by TMS
may result in potentially dilutive issuances of equity securities, the
incurrence of additional debt and amortization expenses related to goodwill and
other intangible assets, which could adversely affect the profitability of TMS.
In addition, acquisitions involve numerous risks, including difficulties in the
assimilation of the operations, products and personnel of the acquired company,
the diversion of management's attention from other business concerns, risks of
entering markets in which TMS has limited or no direct prior experience, and the
potential loss of key employees of the acquired company. TMS is continually
reviewing product and technology acquisition opportunities, although there are
currently no discussions, commitments or agreements, other than the Merger,
which would be material to TMS. In the event that such an acquisition does
occur, there can be no assurance as to the effect thereof on the business,
financial condition or results of operations of TMS.     

                             THE MERGER AGREEMENT

GENERAL

     The following is a summary of certain provisions of the Merger Agreement,
which is attached as Exhibit I to this Proxy Statement - Prospectus.  Such
summary is qualified in its entirety by reference to the Merger Agreement.

THE MERGER

                                       12

State of California. The Merger will be held at a closing which will occur as
promptly as practical following the time at which the shareholders of the
Company shall have adopted the Merger Agreement. The Merger Agreement provides
that, at the Effective Date and subject to the satisfaction of certain
conditions, SAC will be merged with and into the Company. Following the Merger,
the Company will continue as the surviving corporation (the "Surviving
Corporation") and the separate existence of SAC shall cease. In the Merger: (i)
each share of Sequoia Stock issued and outstanding immediately prior to the

     Dana R. Allen, who holds 56% of the Sequoia Stock outstanding as of the

Directors of TMS.

     In the Merger Agreement, the Company has represented and warranted to TMS
and SAC, among other things: (a) that it and each of its subsidiaries is duly

notice of its default under any material agreement.     
    
     In the Merger Agreement, TMS and SAC have represented and warranted to the
Company, among other things: (i) that each of TMS and SAC is a corporation duly
organized, validly existing and in good standing under the laws of the state of
its organization and has all requisite corporate power and authority to own,
lease and operate its properties and to carry on its business as now being
conducted in all material respects; (ii) that they have full corporate power and
authority to execute and deliver the Merger Agreement and to consummate the
transactions contemplated thereby; (iii) that the execution and delivery of the
Merger Agreement will not conflict with or result in a breach of any provision
of their Certificates of Incorporation or Bylaws; (iv) that reports filed by TMS
with the Commission do not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading; (v) that no representation or warranty by TMS or
SAC in the Merger Agreement contains any untrue statement of a material fact or
omits to state a material fact required to be stated therein necessary in order
to make the statements therein, in light of the circumstances in which they were
made, not misleading; (vi) that no fees are owed to any brokers or investment
bankers by TMS or SAC; and (vii) SAC holds sufficient shares of TMS Common Stock
to consummate the Merger.         

     The Company has, among other things, agreed to conduct its operations
according to its ordinary and usual course of business and consistent with past
practice.  In that regard, the Company has agreed that it will not, except as
otherwise expressly provided in the Merger Agreement, engage in certain types of
transactions including to:  (i) issue, sell, set aside or pledge, or authorize
or propose the issuance, sale or pledge of any shares of capital stock of any
class (including Sequoia Stock) or securities convertible into such shares, or
any rights, warrants or options to acquire any such shares or other convertible
securities; (ii) purchase or otherwise acquire, or propose to purchase or
otherwise acquire, any outstanding shares of Sequoia Stock; (iii) declare or pay
any dividend on or distribution of any shares of its capital stock; (iv) propose

any financial arrangement with any employee of the Company; (vi) sell, mortgage
or dispose of any material portion of 

                                       14
<PAGE>
 
the Company's assets; (vii) enter into any material contracts except in the
ordinary course of business; (viii) propose, recommend or authorize any merger
besides the Merger; or (ix) agree in writing or propose to take any of the
foregoing actions or any action which would make any representation or warranty
in the Merger Agreement untrue or incorrect.
    
     Under the Merger Agreement, the Company has agreed to give SAC and its
authorized representatives access to the personnel, offices, and other
facilities and to the books and records of the Company and agreed to permit SAC
to make such inspections as it may require and to cause its officers to furnish
SAC with financial and operating data and other information with respect to the
business and properties of the Company as SAC may from time to time 
request.     

     Except as set forth in the Merger Agreement, or as required by applicable
law, the Merger Agreement provides that the Company shall not, directly or
indirectly, encourage, solicit, participate in or initiate discussions or
negotiations with, or provide any information to, any corporation, partnership,
person or other entity or group (other than TMS or an affiliate or associate of
TMS) concerning any merger, sale of assets, sale of shares of Sequoia Stock or
similar transaction involving the Company or any subsidiary of the Company.

     The Merger Agreement provides that, subject to its terms, each of the
parties will use its best efforts to take or cause to be taken, all actions, and
do, or cause to be done, necessary, proper or advisable under applicable laws
and regulations to consummate and make effective the transactions contemplated
by the Merger Agreement and will use its best efforts to obtain all necessary
consents to the Merger. If at any time after the Effective Date any further
action is necessary or desirable to carry out the purposes of the Merger
Agreement, the parties have agreed that the proper officers and directors of
each party shall take all such necessary action.

     The Merger Agreement provides that TMS, SAC and the Company will consult
with each other before issuing any press release or otherwise making any public
statements with respect to the Merger and shall not issue any such press release
or make any such public statement prior to such consultation, except as may be
required by law.
    
     Although the Merger Agreement does not require that the Merger qualify as a
tax-free reorganization under the Code or as a pooling-of-interests for
accounting and financial reporting purposes, both TMS and Sequoia are unlikely
to complete the Merger in the event either of these treatments are not
applicable to the Merger. In the event either were inapplicable to the Merger
and the parties nonetheless desired to complete the Merger, proxies for approval
of the Merger by Sequoia shareholders would be resolicited.     

TERMINATION; AMENDMENTS; WAIVER

     The Merger Agreement may be terminated and the Merger contemplated thereby
may be abandoned at any time prior to the Effective Date notwithstanding
approval thereof by the shareholders of the Company: (i) by the written mutual
consent of the duly authorized Board of Directors of SAC and the Company; (ii)
by SAC or by the Company, if any representation or warranty of the other party
is or becomes untrue in any material respect or if the other party materially
breaches any of its covenants or agreements in the Merger Agreement; or (iii) by
SAC or the Company if the Effective Date shall not have occurred on or before
March 31, 1996; provided that this termination right shall not be available
to any party whose failure to fulfill any obligation under the Merger Agreement
causes or results in the failure of the Effective Date to occur on or before
such date.     
    
     The Merger Agreement may be amended by actions taken by or on behalf of
the Boards of Directors of the Company and TMS at any time before the Effective
Date but, after the approval of the shareholders of the Company, no amendment
shall decrease the consideration of 2.837 shares of TMS Common Stock to be
received by shareholders for each share held by them.     

     The Merger Agreement provides that all costs and expenses incurred in
connection with the transactions contemplated thereby shall be paid by the party
incurring such expenses.

                              GENERAL INFORMATION

VOTE REQUIRED

     Approval of the Merger Agreement requires the affirmative vote of the
holders of a majority (more than 50%) of the outstanding Sequoia Stock. Each
holder of Sequoia Stock as of the Record Date is entitled to one vote for each
Sequoia Stock held. On the Record Date, there were 1,284,180 shares of Sequoia
Stock outstanding.
    
     Dana R. Allen, President, Chief Executive Officer and Chairman of the 
Company, owns 719,719 shares of Sequoia Stock (approximately 56% of the 
outstanding Sequoia Stock) and has agreed in the Merger Agreement to vote all of
his shares in favor of the Merger Agreement.  Approval of the Merger Agreement 
is assured by Mr. Allen's agreement.     
    
     Approval of the Merger Agreement by the shareholders of TMS is not
required. The Board of Directors of SAC and the Board of Directors of TMS, as
the sole shareholder of SAC, have approved the Merger and the Merger Agreement.
Under the Oklahoma General Corporation Act, approval by the shareholders of a
parent corporation is not required for the merger of a subsidiary with another
corporation.     

VOTING RIGHTS AND PROCEDURES

     Any person signing and mailing the enclosed proxy may vote in person if in
attendance at the Meeting.  Proxies may be revoked at any time before they are
voted by notifying the Secretary of such revocation, in writing, at the Meeting,
or by submitting a later dated proxy.  Sequoia shareholders are encouraged to
vote on the matters to come before the Meeting by marking their preferences on
the enclosed proxy and by dating, signing, and returning the proxy in the
enclosed envelope.  If a preference is not indicated on a proxy, the proxy will
be voted "FOR" the proposal to approve the Merger Agreement.

    
     It is not anticipated that matters other than those described above and in
the Notice of Special Meeting, to which this Proxy Statement - Prospectus is
appended, will be brought before the Meeting for action, but if any other
matters properly come before the Meeting, it is intended that votes thereon will
be cast pursuant to said proxies in accordance with the best judgment of the
proxy holders.     

     With respect to the tabulation of votes on any other matter, abstentions
are treated as present or represented and entitled to vote at the Meeting, while
non-votes by nominees are treated as not being present or represented and not
entitled to vote at the Meeting.

CONVERSION OF SHARES IN THE MERGER

     At the Effective Date, each share of Sequoia Stock issued and outstanding
immediately prior thereto (other than shares of Sequoia Stock held by any
shareholder who shall have perfected his or her right to dissent under the
California Corporations Code) will be automatically converted into the right to
receive 2.837 shares of TMS Common Stock.

EXCHANGE OF CERTIFICATES

    
     American Stock Transfer, as exchange agent (the "Exchange Agent"), will
provide transmittal forms to Sequoia shareholders to be used in forwarding their
certificates for shares of Sequoia Stock into which their Sequoia shares were
converted in the Merger. Until such surrender, certificates representing Sequoia
Stock will be deemed to represent the number of shares of TMS Common Stock into
which such shares of Sequoia Stock were converted in the Merger, except that the
holders of Sequoia certificates will not be entitled to receive dividends or any
other distributions from TMS until such certificates are so surrendered. When
such certificates are surrendered, the holders of TMS certificates issued in the
Merger will be paid, without interest, any dividends or other distributions
which may have become payable with respect to such TMS Common Stock since the
Effective Date.     

                                       16
<PAGE>
 
FRACTIONAL SHARES
    
     No certificates representing fractional shares will be issued by TMS in
respect of TMS Common Stock issued pursuant to the Merger and no TMS dividend,
stock split or interest will relate to any fractional share. No fractional share
interests will entitle the owner thereof to vote or to any rights of a
shareholder of TMS. In lieu of any such fractional shares, TMS shall deliver
whole shares of TMS Common Stock by rounding down to the next number if the
fraction is less than .5 and rounding up to the next highest number if the
fraction is .5 or greater.     

REGISTRATION
    
     TMS has registered the TMS Common Stock issuable upon conversion of the
Sequoia Stock in the Merger pursuant to a filing with the Commission of a
Registration Statement on Form S-4 with respect to, and will take any actions
necessary under the state blue sky or securities laws in connection with, the
issuance of such shares.     

RIGHTS OF DISSENTING SHAREHOLDERS     
    
     Pursuant to Chapter 13 of the California Corporations Code (the
"Corporations Code"), any Sequoia shareholder who desires to receive the fair
market value of his or her Sequoia Stock in cash rather than to receive
TMS Common Stock as part of the Merger may do so if he or she complies with the
provisions of the Corporations Code pertaining to the exercise of dissenters'
rights. The following is a summary of such provisions of the Corporations Code
and is qualified in its entirety by reference to such provisions, copies of
which are attached to this Proxy Statement - Prospectus as Exhibit II.     
    
     Sequoia shareholders have the right to dissent from approval of the Merger
and to demand payment in cash for their shares.  In general, to perfect the
right to dissent, a shareholder must take the following actions: (a) vote
against the Merger or abstain from voting for the Merger; (b) submit a demand in
writing, no later than 30 days after the Approval Date (as such term is defined
below), that Sequoia purchase the shareholder's shares and pay the shareholder
the fair market value of the shares in cash; and (c) within 30 days after the
Approval Date, submit the certificates representing the shares to be purchased,
stamped with a legend identifying them as dissenting shares. The "Approval Date"
is the date Sequoia mails notice of shareholder approval of the Merger pursuant
to Section 1301 of the Corporations Code. Such notice will notify shareholders
of the Approval Date as well as the address to which demands for payment by
dissenting shareholders should be sent. Such notice will constitute an offer by
Sequoia to buy any dissenting shares.    
    
     The demand for payment must state the number and class of the shares held
of record by the shareholder that the shareholder wants Sequoia to purchase. The
demand must state what the shareholder claims to be the fair market value of the
shares as of September 7, 1995, which was the day before the first announcement
of the Merger. The statement of fair market value constitutes an offer by the
shareholder to sell the shares at such price. Assuming that the Merger is
approved by the required vote, shareholders who do not meet those requirements
are bound by the terms of the Merger Agreement.    
    
     If a dissenting shareholder and Sequoia agree that the shares are
dissenting shares and agree upon the fair market value for the shares, Sequoia
will pay the dissenting shareholder the agreed value with interest at the legal
rate from the date of such agreement, within 30 days after the date of the
agreement or within 30 days after any statutory or contractual conditions to the
Merger are satisfied, whichever is later. If, within six months after the
Approval Date, Sequoia denies that the shares are      

                                       17
<PAGE>
 
        
dissenting shares, or Sequoia and the shareholder fail to agree upon the fair
market value of the shares, then the shareholder or Sequoia may seek a court
determination of whether the shares are dissenting shares, the fair market
value of the dissenting shares, or both. The shareholder may recover the amount
the court determines to be the fair market value of each dissenting share
multiplied by the number of dissenting shares Sequoia must purchase, plus
interest at the legal rate from the date of judgment. The judgment is payable
only upon endorsement and delivery to Sequoia of the certificates for the shares
described in the judgment. The cost of the action shall be apportioned as the
court considers equitable, but Sequoia shall pay the costs (including in the 
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate from the date upon which Sequoia notified shareholders of the
Approval Date) if the value awarded by the court for the shares is more than
125% of the price offered by Sequoia. The dissenting shareholder and persons
claiming under the shareholder will be bound by the terms of the Merger
Agreement if the shareholder transfers the shares before submitting them to be
legended or withdraws the demand that Sequoia purchase the shares, or if, within
six months after the Approval Date, Sequoia and the shareholder have neither
agreed on the fair market value of the shares nor filed a petition as set forth
above.     
    
     A vote in favor of the Merger Agreement constitutes a waiver of dissenters'
rights under Chapter 13 of the Corporations Code.  Because a proxy which does
not contain voting instructions will, unless revoked, be voted FOR approval and
adoption of the Merger Agreement and the transactions contemplated thereby, a
holder of shares of Sequoia Stock who votes by proxy and who wishes to exercise
his or her dissenters' rights must, after notifying Sequoia of his or her
intention to dissent, either (a) vote AGAINST the approval and adoption of the
Merger Agreement and the transactions contemplated thereby or (b) abstain from
voting on the approval and adoption of the Merger Agreement and the transactions
contemplated thereby.  Further, a vote against approval of the Merger Agreement
or abstaining to vote for the Merger Agreement does not satisfy the requirement
of a written demand for payment or the other actions required by Chapter 13 of
the Corporations Code to perfect dissenters' rights.  Such written demand for
payment must be in addition to and separate from any proxy regarding the Merger
Agreement.     
    
     Failure to follow the provisions of Chapter 13 of the Corporations Code
will result in a loss of dissenters' rights. In addition, if Sequoia and TMS
abandon the Merger, the right of a dissenting shareholder to be paid the fair
market value of his or her shares will cease.     

STOCK OPTIONS AND WARRANTS     

     In the event the Merger is consummated, Sequoia's stock options and
warrants will be converted into options or warrants to purchase shares of TMS
Common Stock with each such option or warrant being converted into the right to
purchase 2.837 shares of TMS Common Stock for each share of Sequoia Common Stock
purchasable under such option or warrant at an exercise price equal to 35.24% of
the exercise price per share of Sequoia Common Stock under such option or
warrant. Each of the remaining terms and conditions of the outstanding Sequoia
stock options and warrants shall remain in full force and affect and shall be
assumed and accepted by TMS upon the consummation of the Merger.     

EFFECTIVE DATE OF THE MERGER     
    
     If the Merger Agreement is approved by requisite vote of the Sequoia
shareholders, and the other conditions to the Merger are satisfied or waived,
the Merger will become effective upon the filing of a Certificate of Merger with
the Secretary of State of the State of Oklahoma and an Officer's Certificate and
Merger Agreement with the Secretary of State of the State of California.  It is
presently contemplated that the Effective Date will occur on or about March 15,
1996.  The           

                                       18

Effective Date could, however, be delayed to allow for the 30-day time period to
elapse with respect to those shareholders who did not vote in favor of the
Merger or who did not vote at the Meeting, whether in person or by proxy.     

ACCOUNTING TREATMENT

     The Merger is expected to qualify as a "pooling-of-interests" for
accounting and financial reporting.


                           BACKGROUND OF THE MERGER

SUMMARY OF EVENTS     
    
     In the late spring and early summer 1995, discussions began between Maxwell
Steinhardt, President of TMS, and Dana R. Allen, Chairman of Sequoia, concerning
a possible business combination to consolidate the two operations into a company
able to better compete in the imaging industry. Mr. Steinhardt and Mr. Allen
considered the following key issues: technology and product compatibilities
between the companies, distribution approaches, customers, revenue mix, company
cultures, markets of opportunity, company outlooks and possible structures of
the proposed transaction. As a result of these negotiations, the Company
believed that TMS and Sequoia would be highly complementary in technology and
products, share many customers and have the ability to combine technologies,
products, and marketing and selling infrastructures to their mutual benefit.    
    
     In meetings during August and September 1995, the Sequoia Board met and
reviewed Sequoia's future as a small, privately-held company in an increasingly
competitive and technologically changing computer software industry. The Board
believed that in order for Sequoia to continue to compete in the imaging
industry it needed to expand the market share for its existing products, develop
new markets and build a staff of software developers to continue product
innovation. However, the Board believed that although the Company had operated
profitably for 11 consecutive quarters through the fiscal year ended August 31,
1995, and revenues had generally increased from quarter to quarter, net cash
provided by operations was insufficient to fund Sequoia's financial and human
resources needs to rapidly respond to these market opportunities. Moreover, the
Board had concerns regarding the Company's ability, as a privately-held company,
to achieve investment liquidity for the benefit of its shareholders and option
holders.    
    
     To address the issues relating to expansion and the need for additional
human and financial resources, the Board initially considered raising capital
through a private placement. Due to Sequoia's difficulty in the past in raising
significant capital through private placements, and the lack of liquidity for
Sequoia Stock, the Board did not believe that sufficient capital could be raised
on terms, or in a time frame, satisfactory to the Company. A private placement
also did not address the lack of a secondary market for the resale of shares
held by Sequoia's existing shareholders. An initial public offering was also
considered, but the Board concluded that this option was not viable, given the
relatively small size of the Company's revenues and earnings.     
    
     In light of the difficulty of pursuing either a private or public offering
of Sequoia Stock, the Board next considered the prospects of combining its
operations with a company in the imaging industry. The Board desired to locate a
public company with which Sequoia had a strong business relationship, common
customers and complementary products. Based upon these factors, the Board
viewed TMS as an attractive opportunity for a business combination.
The Board also believed that the size of TMS relative to Sequoia was also
important, in that Sequoia's contributions would have greater impact on the
earnings and revenues of the combined entity than it would if Sequoia were
merged with a larger company.     
         
    
     During August 1995, negotiations continued between TMS and Sequoia,
principally through Mr. Steinhardt and Mr. Allen, who reported to their
respective Boards of Directors. Negotiations also involved other officers of
each company, as well as legal counsel for Sequoia and TMS. These negotiations
concentrated primarily on possible structures for the transaction. TMS proposed
that the transaction take the form of an exchange of stock, which was acceptable
to Sequoia, so long as there was a mechanism adopted whereby Sequoia
shareholders would be issued additional shares based upon Sequoia's performance
in the two years following the Merger. Sequoia proposed a basic formula for such
a performance feature, which was acceptable to TMS, and a proposed letter of
intent (the "Letter of Intent") was prepared, that set forth the material terms
pursuant to which TMS would combine with Sequoia by means of a merger with SAC.
    
    
     The Sequoia Board reviewed the Letter of Intent and considered the factors
discussed below. On September 6, 1995, the Letter of Intent was executed, which
provided for a merger in which each share of Sequoia Stock would be converted
into 2.5222 shares of TMS Common Stock (or an aggregate of 4,444,444 shares
(inclusive of shares of TMS Common Stock issuable upon exercise of outstanding
options to purchase Sequoia Stock)). The Letter of Intent also provided for a
performance feature whereby up to 4,444,444 additional shares of TMS Common
Stock would be issued if certain Sequoia net income and revenue goals were
achieved in the two years following the Merger. On the date of announcement of
the Letter of Intent, the closing bid price per share of TMS Common Stock was
$.59.    
        
     A review by Sequoia and TMS of the accounting treatment for the Merger as
contemplated by the Letter of Intent revealed that the performance feature would
prohibit pooling-of-interests accounting treatment. To address this concern, TMS
proposed that a maximum of 4,444,444 shares of TMS Common Stock be issued in the
Merger and that the performance feature be stricken. Sequoia rejected this
proposal and as a result of these additional negotiations, TMS and Sequoia
executed an amended Letter of Intent, which increased the number of shares of
TMS Common Stock issuable in exchange for each outstanding share of Sequoia
Stock to 2.837 shares (or an aggregate of 5,284,366 shares (inclusive of shares
of TMS Common Stock issuable upon exercise of outstanding options to purchase
Sequoia Stock)) and the performance feature was stricken. The principal benefit
to both parties from the this revised structure was that, based upon the 
earnings of both companies for fiscal 1995, the earnings per share of the
combined company would not be less than the earnings per share (adjusted for the
exchange rate in the Merger) of each company separately. By striking the
performance feature, Sequoia shareholders will receive no additional shares of
TMS Common Stock after completion of the Merger, except for the exercise of
outstanding options by the holders thereof.     
    
     On November 7, 1995, TMS, SAC, Sequoia and Dana R. Allen executed the
Merger Agreement.      
    
    On December 6, 1995, TMS, SAC and Sequoia entered into Amendment No. 1 to
the Merger Agreement which, among other things, extended the deadline for
closing of the Merger to March 31, 1996. The terms of such amendment are
reflected in the Merger Agreement attached to this Proxy Statement -Prospectus
as Exhibit I.

SEQUOIA'S REASONS FOR THE MERGER; RECOMMENDATION OF SEQUOIA'S BOARD OF 
DIRECTORS     

    
     THE BOARD OF DIRECTORS OF SEQUOIA (THE "SEQUOIA BOARD") BELIEVES THAT THE
MERGER IS IN THE BEST INTEREST OF SEQUOIA AND ITS SHAREHOLDERS, AND UNANIMOUSLY
RECOMMENDS TO ITS SHAREHOLDERS THAT THEY VOTE FOR THE APPROVAL OF THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.     

    
     The Sequoia Board has given careful consideration to the Merger, the
business of TMS and Sequoia, the potential benefits to be achieved by both
Sequoia and its shareholders, the relative values of Sequoia and TMS, the
interests of management in the Merger, and the risks of the Merger to Sequoia
and its shareholders. See "Risk Factors". Based on the foregoing considerations
discussed in detail below, the Sequoia Board believes that the transactions
contemplated by the Merger Agreement are fair and in the best interest of
Sequoia and its shareholders and unanimously recommends that Sequoia's
shareholders vote FOR approval of the Merger.     

    
BUSINESS SYNERGIES BETWEEN SEQUOIA AND TMS     

        
     The Board believes that Sequoia's products are complementary to the
products and services offered by TMS, and that, because Sequoia and TMS serve
different segments of the digital document imaging market, there are
opportunities to expand market shares without detracting from the sales of
either company.     

    
     TMS operations include products and services, and its products are
primarily text and image retrieval "toolkits," which are software development
products that allow customers to develop new software application or customize
existing applications.  Services include software design and development, custom
programming, CD-ROM Publishing, consulting and the conversion of paper 
documents for use in electronic publishing environment.     

    
     Sequoia's products are primarily document image enhancement and forms
processing software toolkits and applications for OCR (Optical Character
Recognition) assistance. Sequoia does some custom programming, but has more
demand for such services than it can supply.     

    
     The Sequoia Board believes that Sequoia's products complement TMS products.
For instance, creation of a typical document imaging software product may
require the use of seven software development toolkits. Sequoia markets three of
the needed toolkits (ScanFix, GrayFix, and FormFix) and TMS markets another
three (ScanDirector, ViewDirector, and MasterView). The remaining required
program may be acquired from many different vendors. Many customers of the two
companies have been using both Sequoia's and TMS' products for several
years.    
    
     TMS intends to market Sequoia's products to its existing customers and
Sequoia will market TMS' software products and software development services to
its customers. Sequoia's customers often desire custom programming services to
integrate or modify Sequoia's software products into their existing
technologies. The Merger will provide a single source for both products and
services.    
    
     When combined, Sequoia and TMS will field one of the largest suites of core
technologies for the digital document imaging market. This will make the
combined entity more attractive in marketing to large integrators and software
developers looking for a technology partner.

FINANCIAL FAIRNESS     
    
     Due to the relatively high cost to small companies of investment banking
fairness opinions, the Sequoia Board did not obtain an outside independent
valuation of Sequoia, but rather conducted its own analysis of Sequoia's results
of operations, including comparisons of Sequoia to other publicly traded
companies. Furthermore, the Sequoia Board reviewed TMS' historical operations as
set forth in its public filings and internal corporate documents.    
        
             
    
     The Sequoia Board examined the financial ratios of publicly-traded stocks
in the imaging industry and used such ratios as a guide for valuing TMS and
Sequoia. The Board used two principal ratios: stock market price to sales
("Price/Sales"), and stock market price to earnings ("Price/Earnings"). The
Board relied upon the ratios of the following companies in the imaging industry:
(i) Cornerstone Imaging Inc. (Price/Sales: 1.4; Price/Earnings: 21.0); (ii)
Excalibur Technology Corporation (Price/Sales: 13.7; Price/Earnings: not
available (loss)); FileNet Corporation (Price/Sales: 2.9; Price/Earings: 33);
and Innodata Corporation (Price/Sales: 1.17; Price/Earnings: 16.88).     
    
     The analysis began with a valuation of TMS Common Stock. In this process,
the Board did not speculate on possible increases or decreases in the price of
TMS Common Stock as a result of the Merger or other factors. Sequoia recognized
that from the commencement of merger negotiations to the time of the execution
of the Letter of Intent, the bid price of TMS Common Stock was trading in the
range of $.59 to $1.00. On September 7, 1995, the date the Letter of Intent was
executed, the bid price of TMS Common Stock was $.59 per share, which was at the
low end of that range.    
             

    
     The Board valued the TMS Common Stock at $.90 per share, which was in the
range of bid prices during the four months prior to the execution of the Letter
of Intent. At $.90 per share, TMS Common Stock had a Price/Sales ratio of 1.96
per share and a Price/Earnings ratio of 11.25, based on the results of
operations of TMS as of August 31, 1995. Although this value was $.31 per share
higher than the bid price of $.59 per share on the day the Letter of Intent was
executed, the Board believed that other factors such as the TMS net operating
loss carryforward of approximately $5,200,000 as of August 31, 1995 for federal
income taxes and the relatively illiquid market for TMS Common Stock supported a
higher value for the TMS Common Stock.    
    
     A supporting factor of such valuation, though not dispositive because of
the relatively illiquid nature of the market for TMS Common Stock, is that since
September 15, 1995, the bid price of TMS Common Stock has traded in the range of
$.80 to $1.31. On February 5, 1996, the bid price of TMS Common Stock was
$1.19.          

    
     Based upon a market value of TMS Common Stock of $.90 per share, the value
received by Sequoia shareholders and option holders would be approximately $2.55
per share, which would be the equivalent to a Price/Sales ratio of 4.8 and a
Price/Earnings ratio of 22.4. The Board believed that both ratios were
consistent with current valuations of the companies reviewed by the Board.
Moreover this price was in excess of the highest price paid for Sequoia Stock
($1.50 per share, adjusted for the exchange rate in the Merger) in any private 
placement of Sequoia Stock.     
    
     For several reasons, the Board believes that these ratios are the best
indicators for determining the values of TMS Common Stock and Sequoia Stock.
First, book values were not viewed as the principal valuation method because
software companies traditionally have low book values due to the nature of their
principal assets, i.e., software and technical know-how, and that such assets
are not generally reflected as significant assets on the balance sheet. Second,
although Sequoia is privately-held and the market for TMS Common Stock has not
traditionally been active, the Board believed that the investment community will
apply those ratios, or comparable ratios, to the combined company as TMS Common
Stock becomes more actively traded and once listing on a stock exchange is
achieved. The Board believes that the Merger and the increase in revenues to TMS
therefrom is likely to attract more attention from investors and market makers,
who will apply ratios similar to these. However, there can be no assurance that
following the Merger such increased attention will be realized, that a stock
exchange listing, if achieved, will result in increased analyst or investor
attention, or that TMS Common Stock will be valued highly relative to other
companies in the industry.     

                                       21
<PAGE>
 
        
     Following execution of the Letter of Intent, Sequoia's Chief Financial
Officer performed a  due diligence investigation of the financial condition of
TMS, as indicated in TMS' public filings and in internal documents disclosed to
Sequoia. The Board believes that the results of this investigation supported the
Board's conclusions as to the valuation of TMS Common Stock and Sequoia
Stock.    
             
    
Considerations Relating to the Market for TMS Common Stock

     The Sequoia Board believes that, in addition to the strategic business 
advantages and financial fairness of the Merger, Sequoia shareholders will be 
provided with an opportunity for liquidity of their investment. TMS Common 
Stock is publicly traded on the over-the-counter market and, as such, will offer
Sequoia shareholders the ability to sell their shares into a market which has 
not existed for Sequoia.
  
     Although publicly traded, TMS Common Stock has not historically been
actively traded and is not currently eligible for inclusion on the Nasdaq Stock
Market or any other stock exchange. To qualify for listing on the Nasdaq Small
Cap Market, two principal requirements must be satisfied: (i) TMS total assets
must increase from $3,301,280 at November 30, 1995 to over $4,000,000; and (ii)
the market price per share of TMS Common Stock must exceed $3.00 per share.
Based upon the pro forma financial statements giving effect to the Merger, TMS
would have, assuming consummation of the Merger as of November 30, 1995, total
assets of approximately $4,060,593. Therefore, the total assets requirement
would be satisfied if, following consummation of the Merger, total assets remain
at that level or are increased; a decline could mean that, in order to meet the
total assets requirement, additional assets would need to be obtained through
(i) equity or debt financing, (ii) working capital provided by operations or
(iii) acquisitions. TMS Common Stock has traded below the $3.00 minimum bid
price and a reverse stock split may be necessary to cause the bid price of TMS
Common Stock to exceed $3.00. There is no assurance that a reverse split will be
successful in reaching such a minimum price or that the price of TMS Common
Stock would, after adjustment for the reverse split, trade at the same level as
the pre-split shares. TMS has, from time to time, considered a reverse split and
may effect a reverse split in the future; however, there are no present
commitments to do so.

     Because TMS Common Stock is not listed on the Nasdaq Stock Market or an 
exchange, it is considered to be a "penny stock" under the rules of the 
Commission. Acquiring, holding and selling penny stocks involve certain risks 
and considerations. Investors who sell their shares of penny stocks will receive
the bid price per share, less a "markdown," which is compensation charged by the
dealer in the security. Further, trading in penny stocks tends to be limited 
because broker-dealers must comply with special procedures, disclosures and 
practices. Prior to the purchase of a penny stock, investors are required to be 
given a statement which outlines certain risks in investing in penny stocks. 
Generally, this statement pertains to the sales practices of dealers in penny 
stocks, the compensation of such dealers and other matters relating to 
purchasing penny stocks from securities dealers.

     The Sequoia Board recognized that even if an exchange listing is obtained, 
there can be no assurance that the market for TMS Common Stock will become 
liquid or active or that liquidity or activity, if achieved, will be sustained.
                                                                                
PERCENTAGE OWNERSHIP FOLLOWING THE MERGER     

     Assuming that none of the outstanding options to purchase Sequoia's Stock
are exercised prior to the Effective Date and no exercise of dissenters rights
by Sequoia shareholders, immediately following the consummation of the Merger,
Sequoia shareholders will beneficially own TMS Common Stock representing
approximately 30.1% of the outstanding shares.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     As provided in the Merger Agreement, upon the consummation of the Merger,
Dana R. Allen, Chairman, President and Chief Executive Officer of Sequoia, will
be elected to the Board of Directors of TMS and will execute a three-year
employment agreement with Sequoia. See "--Employment Agreement with Dana R.
Allen." The Board of Directors does not view the execution of such employment
agreement as a conflict of interest, inasmuch as the agreement does not confer
upon Mr. Allen substantially greater rights respecting employment than that
afforded him prior to the Merger. TMS however, views the agreement as a
significant measure to preserve the proprietary information of Sequoia.     

OFFICERS, DIRECTORS AND EMPLOYEES

     The Merger Agreement provides that Dana R. Allen is to be nominated
to the Board of Directors of TMS prior to and as a condition to the Merger.
Further, although TMS will have no obligation to continue to employ persons
currently employed by Sequoia, it is anticipated that subsequent to the Merger
the present employees of Sequoia, including officers, will continue to be
employed by Sequoia at the salary or wage rates, terms, conditions and benefits
in effect as of the Effective Date. Moreover, all indemnification provisions
currently in effect under Sequoia's Articles of Incorporation or bylaws with
respect to officers, directors, employees and agents of Sequoia will be
continued in full force and effect.

EMPLOYMENT AGREEMENT WITH DANA R. ALLEN     

                                       22
<PAGE>
 
        
      In connection with and as a condition to the consummation of the Merger,
Sequoia is required to exert its best efforts to execute a three-year
employment agreement with Dana R. Allen. Under such employment contract, Mr.
Allen will receive a salary of $75,000 per year, which shall be reviewed
annually with respect to salary increases. Mr. Allen will be entitled to
participate in employee benefit plans available to employees generally. Sequoia
may terminate Mr. Allen at any time with or without cause, which shall be
effective 90 days from termination notice. In such an event, Mr. Allen shall
receive his annual salary through the effective date of termination. In
addition, the agreement requires Mr. Allen to maintain the confidentiality of
the proprietary and trade secret information of TMS.     

TMS' REASONS FOR THE MERGER

     TMS is acquiring Sequoia as part of its overall strategy of acquiring
independent software companies. TMS believes that the Merger will enable TMS to
expand its capabilities, provide it with the opportunity to serve additional
customers in the software industry, and position it to meet emerging trends
within that industry. In addition, the combination of revenues and assets of
Sequoia will contribute to improving the ability of TMS to include TMS Common
Stock on the Nasdaq Stock Market.


              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

    
     Set forth on the following pages is certain unaudited pro forma combined
financial information with respect to the Merger, including an unaudited pro
forma combined balance sheet as of November 30, 1995 and unaudited pro forma
combined statements of operations for the three months ended November 30, 1995
and the years ended August 31, 1995, 1994 and 1993. The pro forma combined
balance sheet has been prepared on the basis that the Merger occurred on
November 30, 1995. The pro forma combined statements of operations have been
prepared on the basis that the Merger occurred at the beginning of the earliest
year presented. The Merger is expected to qualify as a "pooling-of-interests"
for accounting and financial reporting, and has been structured to qualify as a
tax free reorganization. The unaudited pro forma combined financial statements
should be read in conjunction with the notes thereto and the financial
statements of TMS and Sequoia included elsewhere or incorporated herein. The pro
forma combined results of operations are not necessarily indicative of future
operations of TMS or results that actually would have occurred had the Merger
been effected on the dates indicated.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

    
(1)  Adjustment reflects the exchange of Sequoia common shares at November 30,
     1995 for 2.837 shares of TMS common shares, and the resulting increase in
     additional paid-in-capital.  At November 30, 1995, after giving effect to
     the Merger, TMS would have had outstanding 12,121,730 common shares, par
     value, $.05.  On November 30, 1995, TMS and Sequoia had 8,478,511 and
     1,284,180 Common Shares outstanding, respectively.     

    
(2)  Adjustment reflects offset of TMS' non-current deferred tax asset by the
     amount of Sequoia's non-current deferred tax liability.     

    
(3)  Merger costs incurred of approximately $120,000 have been recognized in the
     pro forma combined statements of operations for the three months ended
     November 30, 1995.  Additional merger costs estimated at approximately
     $30,000 to $50,000 will be charged to operations as incurred.  The pro
     forma combined balance sheet gives effect to $50,000 of such expenses as if
     they had been incurred as of November 30, 1995.     

(4)  Sequoia adopted Statement of Financial Accounting Standards No. 109 (SFAS
     No. 109), Accounting for Income Taxes, as of September 1, 1993, and
     recorded the cumulative effect of the accounting change in its 1994
     Statement of Operations.  The cumulative effect of the accounting change
     ($157,768) has been excluded from the 1994 unaudited pro forma combined
     statement of operations.

    
(5)  In calculating the pro forma weighted average common and common equivalent
     shares, the 2.837 exchange ratio was applied to the Sequoia stock options
     and the exercise price was adjusted to 35.24% of the Sequoia exercise
     price.  Dilutive effect of Sequoia stock options was determined by
     reference to market prices of TMS common stock.

             CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
    
     Myers, Hawley, Morley, Myers & McDonnell, tax counsel to the Company, has
provided the Company with its opinion as to the federal income tax consequences
related to the Merger. Such opinion is based upon current law, accompanying
Treasury Regulations (the "Regulations"), published positions of the Internal
Revenue Service (the "Service"), relevant judicial and other authorities and
upon an assumption that the Merger will be carried out in the manner described
in this Proxy Statement - Prospectus. This opinion is not binding upon the
Service, and no assurance can be given that were the Service to challenge the
stated tax treatment of the Merger it would not be successful. This opinion is 
set forth below.     

     The Merger will constitute a tax-free reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").
    
     No gain or loss will be recognized by a holder of Sequoia Stock upon the
exchange of Sequoia Stock solely for TMS Common Stock.  The aggregate basis of
the TMS Common Stock received in the Merger by a holder of Sequoia Stock will be
the same as the aggregate basis of Sequoia Stock surrendered in exchange
therefor.  The holding period of the TMS Common Stock received in the Merger by
a holder of Sequoia Stock will include the holding period of Sequoia Stock
surrendered in exchange therefor, provided that the holder held Sequoia Stock as
a capital asset as of the Effective Date.     

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY.  DUE TO THE INDIVIDUAL NATURE OF TAX CONSEQUENCES, EACH
SHAREHOLDER IS URGED TO CONSULT HIS TAX ADVISOR WITH RESPECT TO THE TAX
CONSEQUENCES TO HIM OF THE MERGER AND THE EXERCISE OF STATUTORY RIGHTS OF
DISSENTING SHAREHOLDERS, INCLUDING THE EFFECTS OF STATE, LOCAL, FOREIGN AND
OTHER TAX LAWS.

                       RIGHTS OF DISSENTING SHAREHOLDERS
    
     Pursuant to Chapter 13 of the California Corporations Code (the
"Corporations Code"), any Sequoia shareholder who desires to receive the fair
market value of his or her Sequoia Stock in cash rather than to retain his or
her shares of Sequoia Stock as part of the Merger may do so if he or she
complies with the provisions of the Corporations Code pertaining to the exercise
of dissenters' rights. The following is a summary of such provisions of the
Corporations Code and is qualified in its entirety by reference to such
provisions, copies of which are attached to this Proxy Statement - Prospectus as
Exhibit II.     
        
     Sequoia shareholders have the right to dissent from approval of the Merger
and to demand payment in cash for their shares.  In general, to perfect the
right to dissent, a shareholder must take the following actions: (a) vote
against the Merger or abstain from voting for the Merger; (b) submit a demand in
writing, no later than 30 days after the Approval Date (as such term is defined
below), that Sequoia purchase the shareholder's shares and pay the shareholder
the fair market value of the shares in cash; and (c) within 30 days after the
Approval Date, submit the certificates representing the shares to be purchased,
stamped with a legend identifying them as dissenting shares. The "Approval Date"
is the date Sequoia mails notice of shareholder approval of the Merger pursuant
to Section 1301 of the Corporations Code. Such notice will notify shareholders
of the Approval Date as well as the address to which demands for payment by
dissenting shareholders should be sent. Such notice will constitute an offer by
Sequoia to buy any dissenting shares.     
    
     The demand for payment must state the number and class of the shares held
of record by the shareholder that the shareholder wants Sequoia to purchase. The
demand must state what the shareholder claims to be the fair market value of the
shares as of September 7, 1995, which was the day before the first announcement
of the Merger.     
                                       30
<PAGE>
 
The statement of fair market value constitutes an offer by the shareholder to
sell the shares at such price. Assuming that the Merger is approved by the
required vote, shareholders who do not meet those requirements are bound by the
terms of the Merger Agreement.     
    
     If a dissenting shareholder and Sequoia agree that the shares are
dissenting shares and agree upon the fair market value for the shares, Sequoia
will pay the dissenting shareholder the agreed value with interest at the legal
rate from the date of such agreement, within 30 days after the date of the
agreement or within 30 days after any statutory or contractual conditions to the
Merger are satisfied, whichever is later. If, within six months after the
Approval Date, Sequoia denies that the shares are dissenting shares, or Sequoia
and the shareholder fail to agree upon the fair market value of the shares, then
the shareholder or Sequoia may seek a court determination of whether the shares
are dissenting shares, the fair market value of the dissenting shares, or both.
The shareholder may recover the amount the court determines to be the fair
market value of each dissenting share multiplied by the number of dissenting
shares Sequoia must purchase, plus interest at the legal rate from the date of
judgment. The judgment is payable only upon endorsement and delivery to Sequoia
of the certificates for the shares described in the judgment. The cost of the
action shall be apportioned as the court considers equitable, but Sequoia shall
pay the costs (including in the discretion of the court, attorneys' fees, fees
of expert witnesses and interest at the legal rate from the date upon which
Sequoia notified shareholders of the Approval Date) if the value awarded by the
court for the shares is more than 125% of the price offered by Sequoia. The
dissenting shareholder and persons claiming under the shareholder will be bound
by the terms of the Merger Agreement if the shareholder transfers the shares
before submitting them to be legended or withdraws the demand that Sequoia
purchase the shares, or if, within six months after the Approval Date, Sequoia
and the shareholder have neither agreed on the fair market value of the shares
nor filed a petition as set forth above.    
    
     A vote in favor of the Merger Agreement constitutes a waiver of dissenters'
rights under Chapter 13 of the Corporations Code.  Because a proxy which does
not contain voting instructions will, unless revoked, be voted FOR approval and
adoption of the Merger Agreement and the transactions contemplated thereby, a
holder of shares of Sequoia Stock who votes by proxy and who wishes to exercise
his or her dissenters' rights must, after notifying Sequoia of his or her
intention to dissent, either (a) vote AGAINST the approval and adoption of the
Merger Agreement and the transactions contemplated thereby or (b) abstain from
voting on the approval and adoption of the Merger Agreement and the transactions
contemplated thereby.  Further, a vote against approval of the Merger Agreement
or abstaining to vote for the Merger Agreement does not satisfy the requirement
of a written demand for payment or the other actions required by Chapter 13 of
the Corporations Code to perfect dissenters' rights.  Such written demand for
payment must be in addition to and separate from any proxy regarding the Merger
Agreement.     

     Failure to follow the provisions of Chapter 13 of the Corporations Code
will result in a loss of dissenters' rights. In addition, if Sequoia and TMS
abandon the Merger, the right of a dissenting shareholder to be paid the fair
market value of his or her shares will cease.

                      INFORMATION WITH RESPECT TO SEQUOIA

BUSINESS OF SEQUOIA
        
     Sequoia was founded on September 9, 1987.  Sequoia is in the business of
producing innovative software products in the document imaging industry.
Sequoia's principal place of business is located in Burlingame, California and
as of January 31, 1996, Sequoia had 12 employees.     

MANAGEMENT'S DISCUSSION AND ANALYSIS OF CERTAIN RELEVANT FACTORS
    
     The Company's operating results have reflected certain trends. In fiscal
1995, revenue from the sale of ScanFix toolkits began to flatten at the same
time that royalty revenue from ScanFix increased. The increase in royalties
resulted from many customers completing their own products for resale and
reporting royalties to the Company. During the first quarter of fiscal 1996, the
Company's royalties from ScanFix continued to represent a significant percentage
of revenues, amounting to approximately 17% of total revenue. In addition, the
Company saw an increase in revenue from the sale, to existing customers, of
optional feature tools that can be added to the existing ScanFix product. The
Company released its FormFix product in fiscal 1995 and during the first quarter
of fiscal 1996 sales of this product represented approximately 24% of total
revenue. The Company expects royalties from the FormFix product to increase over
the next few years, after customers have completed their own products for
resale.     
       
     Gross profit for fiscal 1995 was 94.5% compared to 90.1% in fiscal 1994. 
The increase can primarily be attributable the increase in royalty revenues 
which essentially results in little or no cost to the Company. During the first 
quarter of fiscal 1996, the Company's gross profit was 91.1%. The slight 
decrease compared to the 94.5% realized in fiscal year 1995 was primarily due
to the change in the mix of product versus royalty revenue. Volatility in gross
profit margins is directly impacted by the mix of product and royalty revenues
and is expected to continue.    
        
     Earnings from operations as a percent of net sales were 35.2% for the 1995 
fiscal year, and 10.8% for the first quarter of fiscal 1996. The decline for the
first quarter of fiscal 1996 was primarily due to nonrecurring legal and 
accounting costs associated with the Merger and increased sales and marketing 
expenses. The Company expects fiscal 1996 earnings from operations as a percent 
of net sales to be less than fiscal 1995 as a result of the same factors that 
affected the first quarter.     
    
     At August 31, 1995, 85 days of net sales were outstanding in accounts
receivable, compared to 58 days of net sales outstanding at August 31, 1994.
This increase in days net sales outstanding is a direct result of a substantial
decrease in allowances for returns and doubtful accounts. At August 31, 1995,
13% of accounts receivable was reserved for returns and doubtful accounts,
compared to 43% of accounts receivable reserved at August 31, 1994. During
fiscal 1995, improved methods of evaluation of sales and collection of overdue
accounts decreased the number of returns and unpaid accounts. Using the value of
accounts receivable before such allowances, 98 days of net sales were
outstanding in accounts receivable at August 31, 1995, compared to 102 days of
net sales outstanding at August 31, 1994.    

     For fiscal 1995, the Company estimates that domestic government sales were
less than 10% of total domestic sales, and estimates that foreign sales were 28%
of total sales.

     Sequoia does not have any material pending or threatened litigation.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS OF SEQUOIA

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Sequoia has no material business relationships with, did not engage in any
material transactions with and had no material indebtedness due from, any of its
directors and officers or any member of their families or their affiliates.

                         DESCRIPTION OF SEQUOIA STOCK
    
     The only classes of capital stock of Sequoia authorized by the Articles of
Incorporation of Sequoia, as amended, consist of 20,000,000 shares of common
stock, no par value ("Sequoia Stock") and 10,000,000 shares of preferred stock,
of which 70,000 shares have been designated as Series A Preferred Stock, and
none of the authorized shares of such series of preferred stock are outstanding.
There were 1,284,180 shares of Sequoia Stock issued and outstanding on the
Record Date.  As of January 31, 1996, there were options outstanding to purchase
578,656 shares of Sequoia Stock.     

     Holders of Sequoia Stock are entitled to one vote for each share of Sequoia
Stock held on all matters submitted to a vote of shareholders.  Pursuant to the
Articles of Incorporation of Sequoia, in the election of directors, shareholders
are permitted to cumulate their votes.  All issued and outstanding shares of
Sequoia Stock are fully paid and non-assessable.

        COMPARATIVE RIGHTS OF TMS SHAREHOLDERS AND SEQUOIA SHAREHOLDERS

     If the proposed Merger is consummated, the Sequoia shareholders will become
holders of shares of TMS Common Stock. Thereafter, the rights and privileges of
such shareholders will be governed by the provisions of the Oklahoma General
Corporation Act (the "OGCA") and the Certificate of Incorporation and Bylaws of
TMS. A comparison of the various rights of a shareholder of Sequoia as governed
by the Corporations Code and Sequoia's Articles of Incorporation and Bylaws,
with such rights of a shareholder of TMS as governed by the OGCA and the
Certificate of Incorporation and Bylaws of TMS is set forth below. This summary
does not purport to be a complete statement of all of the differences in the
rights of such holders and is qualified in its entirety by reference to the
above-mentioned laws, Certificate of Incorporation and Bylaws.

DISSENTERS' RIGHTS
    
     Under the Corporations Code, shareholders who dissent from certain
corporate actions, such as mergers and other corporate "reorganizations," may in
certain circumstances, demand appraisal of, and obtain payment for, the "fair
value" of their shares by following the procedures prescribed in Chapter 13 of
the Corporations Code. Such statutory procedures are described elsewhere in this
Proxy Statement - Prospectus. Although shareholders of an Oklahoma corporation
who dissent from such corporate actions are also provided appraisal rights, the
right to dissent and therefore exercise appraisal rights must be exercised in a
different manner than that required under the Corporations Code. Specifically,
under the OGCA, shareholders who desire to exercise their appraisal rights and
dissent from such corporate action must provide express written notice of their
intent to exercise such rights prior to the holding of the shareholder vote for
approval of the action. Abstention from, or merely voting against approval is
not sufficient under the OGCA for providing notice of one's intent to exercise
his or her appraisal rights. In contrast, under the Corporations Code, Sequoia
shareholders are permitted to exercise their appraisal rights and thereby
dissent from such corporate actions at any time within 30 days after shareholder
approval of the corporate action provided that the shareholder voted against the
corporate action or abstained from voting thereon.      

CUMULATIVE VOTING
    
     The right of Sequoia shareholders to cumulate their votes in connection
with the election of directors is guaranteed by the Corporations Code.
Cumulative voting provisions are intended to aid minority shareholders in
securing representation on the Board of Directors. At each election of
directors, every shareholder entitled to vote in such election has the right to
demand, before the taking of such vote, to vote, in person or by proxy, the
number of shares owned by him or her for as many persons as there are directors
to be elected and for whose election he or she has a right to vote, or cumulate
his or her votes by giving one candidate as many votes as the number of such
directors multiplied by the number of his or her shares, or by distributing such
votes on the same principle among any number of such candidates.     
    
     Under the OGCA, cumulative voting is only allowed if it is so provided for
in a corporation's Certificate of Incorporation. As the Certificate of
Incorporation of TMS does not include a provision granting shareholders the
right to cumulate votes, no such rights will be available to Sequoia
shareholders subsequent to the Merger. Accordingly, the holders of more than 51%
of the shares will be able to elect the Board of Directors and minority
shareholders will not be able to elect a representative to the Board.     

RIGHT TO CALL SPECIAL MEETINGS
    
     Under the Corporations Code, shareholder(s) entitled to cast at least ten 
percent of the votes at the meeting may, upon request in writing to the Chairman
of the Board, President, Vice President or Secretary of the     

                                       35
<PAGE>
 
corporation, demand that a special meeting of the corporation's shareholders be
held. The OGCA has no corresponding provision and special meetings of
shareholders may only be called by the corporation's board of directors. As a
consequence, shareholders have no right to require that the corporation hold a
special meeting to address issues of concern that may be raised by shareholders.

RIGHT TO APPROVE AND REMOVE DIRECTORS
    
     Under the Corporations Code, shareholders: (i) are entitled to elect
directors to fill vacancies which are not filled by the board of directors; (ii)
may hold a special meeting to elect a completely new board of directors when the
filling of a vacancy by the board of directors results in a board of directors
in which less than a majority of directors were elected by the shareholders; and
(iii) provided that the suit is brought by holder of ten percent or greater of
any class of outstanding securities, may bring suit to remove a director of the
basis of fraudulent or dishonest acts or gross abuse of authority or discretion
with reference to the corporation and may bar the reelection of any director so
removed for a period prescribed by the court. None of these rights are available
to shareholders of an Oklahoma corporation.     

RIGHT TO REVIEW CORPORATE BOOKS AND RECORDS

     Under the Corporations Code, shareholders are granted broad rights to
obtain copies of and review corporate accounting books and minutes of board and
shareholder meetings upon written demand and may review such records at any
reasonable time during the corporation's usual business hours. While
shareholders are provided similar rights under the OGCA, the corporation may
require that the shareholder provide the corporation with a proper purpose
before permitting the shareholder to inspect such books and records.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Corporations Code and the OGCA both provide for the indemnification of
officers and directors of the corporation under certain circumstances. There is
a distinction however, between the implementation of the indemnification
provisions of each state's law. Specifically, under the Corporations Code, an
officer or director is not entitled to receive indemnification in the event of
any settlement of any judicial or other proceeding unless the settlement is
approved by the court. Approval of the court is not required under the OGCA.

     The validity of the TMS Common Stock offered hereby will be passed upon for

                         Independent Auditors' Report
                         ----------------------------


The Board of Directors
Sequoia Computer Corporation:


We have audited the accompanying balance sheets of Sequoia Computer Corporation
(the Company), dba Sequoia Data Corporation, as of August 31, 1995 and 1994, and
the related statements of earnings, shareholders' equity, and cash flows for the
years then ended.  These financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
    
As discussed in Note 12 to these financial statements, the Company is expected
to merge with TMS, Inc., a publicly held computer software company, early in the
Company's fiscal 1996, subject to negotiation and execution of a definitive
agreement between the two companies.     

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Sequoia Computer Corporation as
of August 31, 1995 and 1994, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.
    
As discussed in Notes 3 and 9 to the financial statements, in 1994 the Company
adopted the provisions of Statement of Financial Accounting Standards No. 109,
Accounting for Income Taxes.

                         Notes to Financial Statements

                  November 30, 1995 and 1994 (Unaudited), and
                           August 31, 1995 and 1994


(1)  Description of Company

     Sequoia Computer Corporation (the Company), dba Sequoia Data Corporation,
     was incorporated in the state of California in 1987.  The Company develops
     and markets innovative software products in the document image processing,
     image enhancement, forms processing, and data entry industries.  The
     Company's products include ScanFix, FormFix, and GrayFix software tool
     kits.

(2)  Unaudited Financial Information

     The unaudited interim financial statements as of November 30, 1995, and for
     the three-month periods ended November 30, 1995 and 1994, reflect all
     adjustments which are, in the opinion of management, necessary for a fair
     presentation of financial position, results of operations and cash flows.
     All adjustments are normal and recurring.  The financial information for
     the interim periods may not necessarily be indicative of the results
     expected for the year.

(3)  Summary of Significant Accounting Policies

     Revenue Recognition

     Revenue is recognized at the time of shipment, net of allowances for
     estimated future product returns.  The Company's obligations after the
     point of sale are insignificant.  Costs relating to any post sale
     obligations are therefore expensed as incurred.

     Cash and Cash Equivalents

     Cash and cash equivalents consist primarily of highly liquid money market
     accounts carried at cost plus accrued interest, which approximates market
     value.  All cash equivalents have maturities of less than three months at
     the time of purchase.

     Short-Term Investments

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
     No. 115, Accounting for Certain Investments in Debt and Equity Securities,
     for investments held as of September 1, 1994.  Under the provisions of
     SFAS No. 115, the Company has classified its investments as "available-for-
     sale." Such investments are recorded at fair value and unrealized gains and
     losses, if material, are reported as a separate component of equity until
     realized.  The cost of securities sold is based upon the specific
     identification method.  There was no cumulative effect on earnings as a
     result of the adoption of SFAS No. 115.

     Property and Equipment

     Property and equipment are stated at cost.  Depreciation is computed using
     the straight-line method over the estimated useful lives of the respective
     assets, which range from three to seven years.

                                                                     (Continued)

                         Notes to Financial Statements


     Capitalized Software Development Costs

     The Company capitalizes software development costs after the technological
     feasibility of the product has been established in accordance with SFAS No.
     86, Accounting for the Cost of Computer Software to be Sold, Leased, or
     Otherwise Marketed.  Such costs are amortized using the straight-line
     method over the estimated economic life of the product, which is generally
     two years from the date of product release.  The amortization expense was
     $11,655 and $2,562 for each of the three months ended November 30, 1995 and
     1994, respectively, and $26,545 and $4,270 for each of the years ended
     August 31, 1995 and 1994, respectively.  This amortization approximates or
     is greater than that which would be determined using the ratio of current
     product revenue to the total anticipated product revenue.  The Company
     periodically evaluates unamortized capitalized software costs to determine
     that such costs are recoverable.

     Income Taxes

     Effective September 1, 1993, the Company adopted the provisions of SFAS No.
     109, Accounting for Income Taxes, and has reported the cumulative effect of
     that change in the method of accounting for income taxes in the
     accompanying 1994 statement of earnings.  SFAS No. 109 prescribes an asset
     and liability approach that results in the recognition of deferred tax
     assets and liabilities for the expected future tax consequences of events
     that have been recognized in the Company's financial statements or tax
     returns.  In estimating future tax consequences, SFAS No. 109 generally
     considers all expected future events other than future enactment's of
     changes in tax laws or rates.

     Patent Costs

     Patent costs are comprised of capitalized costs associated with obtaining
     patent rights for certain software products.  Such costs will be amortized
     over the useful life of the patents on the straight-line method once the
     patents have been obtained.

(4)  Property and Equipment

     Property and equipment consisted of the following as of November 30 and
     August 31:

     exercisable at such times and under such conditions as determined by the
     Board of Directors at the date of grant.  To date, all options have been
     issued with an exercise price no less than the fair value at the date of
     grant.  The fair value of the Company's stock is determined by the Board of
     Directors.  As of November 30, 1995, and August 31, 1995, 578,656 options
     were outstanding of which 444,656 were vested, and as of August 31, 1994,

(7)  Preferred Stock

     Each share of Series A preferred stock is convertible at the option of the
     shareholder at a rate of one share of common stock for one share of Series
     A preferred stock.  Preferred stock would be automatically converted by the
     Company to common stock on the occurrence of any major event.

     In addition, preferred stock shareholders have preference over common stock
     shareholders in a liquidation, and would receive the first 15 cents per
     share of any dividend announced by the Company, on a noncumulative basis.
     To date, no dividends have been announced by the Company.

     During the three months ended November 30, 1995, the preferred stock was
     converted to common stock.

(8)  Retirement Savings Plan

     The Company has established a retirement savings plan that is available to
     all employees with a minimum of five years of service.  Employees may elect
     to contribute up to 15% of their annual salary, subject to special
     limitations imposed by the Internal Revenue Service.  The Company made no
     contributions to the plan for the three months ended November 30, 1995 and
     1994, or for the years ended August 31, 1995 and 1994.

(9)  Income Taxes

     As discussed in Note 2, the Company adopted SFAS No. 109 as of September 1,
     1993.  The cumulative effect of this change in accounting for income taxes

     As of August 31, 1995, the Company has federal net operating loss
     carryforwards of approximately $273,000, which expire in the years 2005
     through 2008.

     The state of California allows 50% of net operating losses incurred to be
     carried forward for five years.  Accordingly, the Company has a net
     operating loss carryforward for state tax purposes of approximately $32,000
     as of August 31, 1995.  The carryforward expires in the year 1998.

     The Internal Revenue Code of 1986 and the California Conformity Act of 1987
     substantially restrict the ability of a corporation to utilize existing net
     operating losses in the event of an "ownership change" of the Company, as
     defined.

(12) Subsequent Events     

     On September 6, 1995, the Company entered into a Letter of Intent for a
     plan of merger with TMS, Inc. (TMS), a publicly held computer software
     company.  On September 21, 1995, the Company and TMS agreed to amend the
     Letter of Intent for changes in the number of TMS shares to be issued for
     all of the issued and outstanding shares of the Company's common stock.
     Under the amended Letter of Intent, TMS will issue a maximum of 5,000,000
     shares of its common stock in exchange for all outstanding shares of the
     Company's common stock.  In addition, holders of the Company's common stock
     options at the time of the merger will receive TMS common stock options of
     corresponding value.  The Company anticipates that the merger will be
     consummated during the first quarter of the Company's fiscal 1996 and will
     be accounted for using the pooling-of-interests method.  Consummation of
     the merger is subject to several conditions, including negotiation and
     execution of a definitive agreement.

     In addition, in anticipation of the merger, the holders of all of the
     preferred stock converted their holdings to common stock in October at the
     rate of one share of common stock for one share of preferred stock, as
     outlined in Note 6.

action on the part of the holder thereof, be transformed and converted into the
right to receive, upon surrender of the certificate for such share of Sequoia
Common Stock, the Consideration; (iii) each share of common stock of SAC
outstanding prior to the Merger will, by said occurrence and with no further
action on the part of the holder thereof, be transformed and converted into 100
shares of Sequoia Common Stock, so that thereafter TMS will be the sole and
exclusive owner of equity securities of Sequoia; (iv) the then-serving officers

     2.02.  CONSIDERATION.  Pursuant to the Merger each Sequoia Shareholder
shall be enti tled to receive at the Closing, in respect of each share of

                                  ARTICLE III

                CONVERSION AND EXCHANGE OF SEQUOIA COMMON STOCK

     3.01.  CONVERSION AND EXCHANGE OF SHARES.  The manner of converting the
shares of Sequoia Common Stock issued and outstanding immediately prior to the
Closing Time of the Merger into shares of TMS Common Stock shall be as follows:

            (a)  At the Closing Time:

                                      I-6
<PAGE>
 
                 (i)    Each share of Sequoia Common Stock issued and
     outstanding immediately prior to the Closing Time shall, by virtue of the
     Merger and without any action on the part of the holder thereof,
     automatically be converted into 2.837 fully paid and nonassessable shares
     of TMS Common Stock (which, assuming 1,284,180 shares of Sequoia Common
     Stock outstanding, shall equal 3,643,219 shares of TMS Common Stock).

            (b)  After the Closing Time.

                 (i)    Each Sequoia Shareholder shall be entitled, upon
     surrender to TMS of an outstanding certificate or certificates (duly
     endorsed and in all respects in proper form for transfer), theretofore
     representing shares of Sequoia Common Stock, to receive therefor a
     certificate or certificates representing the number of full shares of TMS
     Common Stock to which such Sequoia Shareholder is entitled. Until so
     surrendered, each such outstanding certificate which prior to the Closing
     Time represented shares of Sequoia Common Stock shall be deemed for all
     corporate purposes (subject to the further provisions of this Section
     3.01(b)(i)) to evidence ownership of the number of shares of TMS Common
     Stock into which such shares of Sequoia Common Stock shall have been so
     converted. After the Closing Date, there shall be no further registry of
     transfers on the records of shares of Sequoia Common Stock outstanding
     immediately prior to the Closing Date, and, if certificates representing
     such shares are presented to TMS, they shall be canceled and exchanged for
     TMS Common Stock as herein provided.

                 (ii)   Neither certificates nor scrip for fractional shares of
     TMS Common Stock will be issued, but TMS shall issue and deliver whole
     shares of TMS Common Stock taking into account any fractional shares
     created by reason of the Merger by rounding down to the next lowest number
     if such fraction is less than .5, and rounding up to the next highest
     number if such fraction is .5 or greater.

     3.02.  VESTED RIGHTS AND NON-VESTED RIGHTS.  At Closing, all unexercised
Vested Rights and Non-Vested Rights will be converted to options to purchase
shares of TMS Common Stock, with each such Right entitling the holder thereof to
purchase 2.837 shares of TMS Common Stock for each share of Sequoia Common Stock
purchasable thereunder, at an exercise price equal to 35.24% of the exercise
price per share of Sequoia Common Stock under such Right.  The expiration date
of Vested Rights which, by their terms in effect as of the date of this
Agreement, expire on or before the Closing Date, shall be extended to a date
ninety (90) days following the Closing Date.

     3.03.  DIVIDENDS; TRANSFER TAXES.  No dividends or other distributions that
are declared after the Closing Date on TMS Common Stock and are payable to the
holders of record thereof after the Closing Date will be paid to persons
entitled by reason of the Merger to receive certificates representing TMS Common
Stock until such persons surrender their certificates which prior to the Closing
Date represented Sequoia Common Stock.  Upon such

                                      I-7
<PAGE>
 
surrender, there shall be paid to the person in whose name the certificates
representing such TMS Common Stock shall be issued, any dividends or other
distributions which shall have become payable with respect to such TMS Common
Stock between the Closing Date and the time of such surrender.  In no event
shall the person entitled to receive such dividends or other distributions be
entitled to receive interest on such dividends or other distributions be
entitled to receive interest on such dividends or other distributions.  If any
cash or certificate representing TMS Common Stock is to be paid to or issued in
a name other than that in which the certificate surrendered in exchange therefor
is registered, it shall be a condition of such exchange that the certificate so
surrendered shall be properly endorsed and otherwise in proper form for transfer
and that the person requesting such exchange shall pay to TMS any transfer or
other taxes required by reason of the issuance of the certificates for such TMS
Common Stock in a name other than that of the registered holder of the
certificate surrendered, or shall establish to the satisfaction of TMS that such
tax has been paid or is not applicable.  Notwithstanding the foregoing, neither
TMS nor any party hereto shall be liable to Sequoia for any TMS Common Shares or
dividends or other distributions thereon delivered to a public official pursuant
to applicable escheat or unclaimed property laws.  No fees or other charges
shall be assessed or imposed by TMS or any person acting for or on behalf of
TMS, upon holders of Sequoia Common Stock who surrender such shares for exchange
in connection with this Agreement.

     3.04.  DISSENTING SHARES.  The provisions of Section 3.01 through 3.03
inclusive shall not apply to Sequoia Common Stock (the "Dissenting Shares") held
by Sequoia Shareholders who do not vote such Sequoia Common Stock in favor of
the approval and adoption of this Agreement and the Merger and who deliver a
written notice to Sequoia in the manner required by Section 1300 et seq. on the
California Corporation Law, stating the intention to demand payment of the fair

     TMS and SAC hereby represents and warrants to Sequoia and to the Seller:

the Closing be a corporation duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of incorporation and has
the requisite corporate power and authority to carry on its business as it is
now being conducted.  Each of TMS and SAC is, or will prior to the Closing be
duly qualified as a foreign corporation to do business, and is in good standing,
in each jurisdiction where the character of its properties owned or leased or
the nature of its activities makes such qualification necessary.

     4.02.  AUTHORITY RELATIVE TO THIS AGREEMENT.  TMS and SAC each has the
requisite corporate power and authority to enter into this Agreement and to
carry out its respective obligations hereunder.  The execution and delivery of
this Agreement and the consummation of the transactions contemplated hereby have
been duly authorized and approved by the governing bodies of TMS and SAC and no
other corporate proceedings on the part of TMS or SAC are necessary to approve
and adopt this Agreement or to approve the consummation of the Merger, including
delivery of the Consideration.  This Agreement has been duly and validly
executed and delivered by SAC and by TMS and constitutes a valid and binding
Agreement of SAC and TMS, enforceable in accordance with its terms.

     4.03.  ABSENCE OF BREACH; NO CONSENTS.  The execution, delivery and
performance of this Agreement, and the performance by SAC and TMS of its
obligations hereunder (except for compliance with any regulatory or licensing
laws applicable to the business of SAC, all of which, to the extent applicable
to TMS and SAC, will be satisfied in all material respects prior to the Closing)
do not, except as disclosed in Schedule 4.03, (i) conflict with or result in a
breach of any of the provisions of the Certificates of Incorporation or By-Laws
of TMS or SAC, (ii) contravene any law, rule or regulation of any State of or of
the United States, or any applicable foreign jurisdiction, or any order, writ,
judgment, injunction, decree, determination or award, or cause the suspension or
revocation of any authorization, consent, approval or license, presently in
effect, which affects or binds TMS or SAC or any of its or their material
properties, except where such contravention will not have a material adverse
effect on the

                                      I-9
<PAGE>
 
business, condition (financial or otherwise) or operations of TMS or SAC, (iii)
conflict with or result in a material breach of or default under any material
indenture or loan or credit Agreement or any other material Agreement or
instrument to which TMS or SAC is a party or by which it or they or any of its
or their material properties may be affected or bound, (iv) require the
authorization, consent, approval or license of any third party of such a nature
that the failure to obtain the same would have a material adverse effect on the
business of TMS or SAC, or (v) constitute grounds for the loss or suspension of
any permits, licenses or other authorizations material to the business of TMS or
SAC.

     4.04.  BROKERS.  No broker, finder or investment banker is entitled to any
brokerage, finder's or other fee or commission in connection with this Agreement
or the Merger or any related transaction based upon any agreements, written or
oral, made by or on behalf of TMS or SAC.

     4.05.  CAPITALIZATION.  The authorized capital stock of TMS consists of
50,000,000 shares of TMS Common Stock and 1,000,000 shares of preferred stock.
There is no other capital stock authorized for issuance.  As of the date of the
TMS Balance Sheet, 8,404,947 shares of TMS Common Stock were validly issued and
outstanding, fully paid and nonassessable, no shares of TMS Common Stock were
held in treasury, and no shares were reserved for issuance, nor were there
outstanding any options, warrants, convertible instruments or other rights,
agreements or commitments to acquire TMS Common Stock, except as described in
the Audited Financial Statements of TMS or in the Public Reports (as defined in
Section 4.07).

     4.06.  INVESTMENT.  TMS is acquiring the shares of Sequoia Common Stock for
its own account without a view to the distribution thereof within the meaning of
the Securities Act, and will not directly or indirectly offer or sell the shares
of Sequoia Common Stock or solicit any offer to purchase such shares, other than
in conformity with the Securities Act.  TMS acknowledges that the shares of
Sequoia Common Stock have not been registered under the Securities Act, and TMS
will not transfer any such shares except in compliance with such Securities Act
or an opinion that registration is not required under the Securities Act, and a
legend to that effect shall be placed on the certificates representing the
shares of Sequoia Common Stock.

     4.07.  FILINGS WITH THE SEC.  TMS has filed Quarterly Reports on Form 10-Q
for the fiscal quarters ended May 31, 1995 (the "Most Recent TMS Fiscal Quarter
End"), February 28, 1995 and November 30, 1994, and a Form 10-K Annual Report
for the fiscal year ended August 31, 1995 with the SEC as required under the
Securities Act and the Securities Exchange Act of 1934 (the "Exchange Act")
(collectively, the "Public Reports").  Each of the Public Reports has complied
with the Securities Act and the Exchange Act in all material respects.  None of
the Public Reports, as of their respective dates, contained any untrue statement
of a material fact or omitted to state a material fact necessary in order to
make the statements made therein, in light of the circumstances under which they
were made, not misleading.

                                      I-10
<PAGE>
 
     4.08.  FINANCIAL STATEMENTS.  The Audited Financial Statements of TMS and
the financial statements included in or incorporated by reference into the
Public Reports (including the related notes and schedules) have been prepared in
accordance with GAAP, applied on a consistent basis throughout the periods
covered thereby, and present fairly the financial condition of TMS as of the
indicated dates and the results of operations of TMS for the indicated periods;
provided, however, that the interim statements are subject to normal year-end
adjustments, consistent with the past practices of TMS.

     4.09.  EVENTS SUBSEQUENT TO THE DATE OF THE TMS BALANCE SHEET.  Since the
date of the TMS Balance Sheet, there has not been any material adverse change in
the business, financial condition, operations or results of operations of TMS
taken as a whole.

     4.10.  ENVIRONMENT, HEALTH AND SAFETY.  Except as set forth in the Public
Reports:  (i) TMS has complied with all Environmental, Health and Safety Laws,
and has not been notified that any action, suit, proceeding, hearing,
investigation, charge, complaint, claim, demand, or notice has been filed or
commenced against TMS alleging any failure to so comply; and (ii) TMS has no
liability for damage to any site, location, or body of water (surface or
subsurface), for any illness of or personal injury to any employee or other
individual, or for any reason under any Environmental, Health, and Safety Law.

     4.11.  OWNERSHIP OF ASSETS.  Each of TMS and its Subsidiaries has, except
as disclosed in the Public Reports or the TMS Financial Statements, good,
marketable and insurable title, or valid, effective and continuing leasehold
rights in the case of leased property, to all real property (as to which, in the
case of owned property, such title is fee simple) and all personal property
owned or leased by it or used by it in the conduct of its business in such a
manner as to create the appearance or reasonable expectation that the same is
owned or leased by it, free and clear of all liens, claims, encumbrances and
charges, except liens for taxes not yet due and minor imperfections of title and
encumbrances, if any, which singly and in the aggregate are not substantial in
amount and do not materially detract from the value of the property subject
thereto or materially impair the use thereof.  TMS does not know of any
potential action by any party, governmental or other, and no proceedings with
respect thereto have been instituted of which TMS has notice, that would
materially affect the ability of Sequoia to use and to utilize each of such
assets in its business or in the business of its Subsidiaries.  TMS has received
no notices from any mortgagee regarding any properties owned by TMS.

     4.12.  PROPRIETARY RIGHTS.  (i)  TMS and each of its Subsidiaries possesses
full ownership of, or adequate and enforceable long-term licenses or other
rights to use (without payment), all Proprietary Rights owned by or registered
in the name of TMS or any of its Subsidiaries or used in the business of TMS or
any of its Subsidiaries. No claim is pending or, to the best of knowledge of
TMS, threatened to the effect that the operations of TMS infringe upon or
conflict with the asserted rights of any other person under any Intellectual
Property, and there is no basis for any such claim (whether or not pending or
threatened).  No claim is pending or threatened to the effect that the
Proprietary Rights owned or licensed by TMS, or which TMS otherwise has the
right to use, is invalid or unenforceable by TMS, and there is no basis for any
such claim (whether or not pending or threatened).  To the best knowledge

                                      I-11
<PAGE>
 
of TMS, all technical information developed by and belonging to TMS which has
not been patented has been kept confidential.  TMS has not granted or assigned
to any other person or entity any right to manufacture, have manufactured,
assemble or sell the services of TMS, except for standard value-added reseller
agreements.

            (i)  To the best knowledge of TMS, no third party has claimed or has
reason to claim that any person employed by or affiliated with TMS has:  (a)
violated or may be violating any of the terms or conditions of his employment,
non-competition or non-disclosure agreement with such third party, (b) disclosed
or may be disclosing or utilized or may be utilizing any trade secret or
proprietary information or documentation of such third party or (c) interfered
or may be interfering in the employment relationship between such third party
and any of its present or former employees.  No third party has requested
information from TMS which suggests that such a claim might be contemplated.  To
the best knowledge of TMS, no person employed by or affiliated with TMS has
employed or proposes to employ any trade secret or any information or
documentation proprietary to any former employer, and to the best knowledge of
TMS, no person employed by or affiliated with TMS has violated any confidential
relationship which such person may have had with any third party, in connection
with the development, manufacture or sale of any proposed service of TMS and TMS
has no reason to believe there will be any such employment or violation.  To the
best knowledge of TMS, neither the execution or delivery of this Agreement, nor
the carrying on of the business of TMS as officers, employees or agents by any
officer, director or key employee of TMS, nor the conduct or proposed conduct of
the business of TMS, will conflict with or result in a breach of the terms,
conditions or provisions of or constitute a default under any contract, covenant
or instrument under which any such person is obligated.

     4.13.  UNDISCLOSED LIABILITIES.  Except as otherwise set forth in the
Public Reports, TMS has no Liabilities except for: (i) Liabilities set forth on
the face of the Most Recent Balance Sheet of TMS (or in any notes thereto); and
(ii) Liabilities which have arisen after the Most Recent TMS Fiscal Quarter End
in the ordinary course of business.

     4.14.  LEGAL COMPLIANCE.  Except as otherwise disclosed in the Public
Reports, TMS has complied with all applicable laws (including rules,
regulations, codes, plans, injunctions, judgments, orders, decrees, rulings and
charges thereunder) of federal, state, local and foreign governments and all
agencies thereof, except where the failure to so comply would not have a
material adverse effect upon the financial condition or operations of TMS, and
no action, suit, proceeding, hearing, investigation, charge, complaint, claim,
demand, or notice has been filed or commenced against TMS alleging any failure
to so comply.

     4.15.  LITIGATION.  Except as otherwise set forth in the Public Reports,
TMS is not: (i) subject to any outstanding injunction, judgment, order, decree,
ruling, or charge; or (ii) a party or threatened to be made a party to any
action, suit, proceeding, hearing, or investigation of, in, or before any court
or quasi-judicial or administrative agency of any federal, state, local, or
foreign jurisdiction of or before any arbitrator, the result of which could have
a material adverse effect on its financial condition or operations of TMS.

                                      I-12

     4.16.  PRODUCT LIABILITY.  Except as otherwise set forth in the Public
Records, TMS has no liability arising out of any injury to individuals or
property as a result of the ownership, possession, or use of any product
manufactured or sold by TMS, the result of which could have a material adverse
effect on its business or operations.

     4.17.  FOREIGN CORRUPT PRACTICES ACT.  TMS has not taken any action which
would cause it to be in violation of the Foreign Corrupt Practices Act of 1977,
as amended, or any rules and regulations thereunder.  To the best knowledge of
TMS after due inquiry, there is not now, and there has never been, any
employment by TMS of, or beneficial ownership in TMS by, any governmental or
political official in any country in the world.

     4.18.  VOTING IN FAVOR OF THE MERGER.  The Merger and the other agreements
and transactions contemplated by the Agreement have been voted in favor of and
adopted by the Board of Directors of TMS.

     4.19.  FULL DISCLOSURE.  The documents, certificates and other writings
furnished or to be furnished by or on behalf of TMS to Sequoia pursuant to the
provisions of this Agreement, taken together in the aggregate, do not and will
not contain any untrue statement of a material fact, or omit to state any
material fact necessary to make the statements made, in the light of the
circumstances under which they are made, not misleading.

     Sequoia), nor has any governmental entity indicated to Sequoia an intention
     to conduct the same, and (b) there is no action, suit or proceeding pending
     or, to the best of the knowledge of Sequoia, threatened against or
     affecting Sequoia or its Subsidiaries at law or in equity, or before any

     marketable and insurable title, or valid, effective and continuing
     leasehold rights in the case of leased property, to all real property (as
     to which, in the case of owned property, such title is fee simple) and all
     personal property owned or leased by it or used by it in the conduct of its
     business in such a manner as to create the appearance or reasonable
     expectation that the same is owned or leased by it, free and clear of all
     liens, claims, encumbrances and charges, except liens for taxes not yet due
     and minor imperfections of title and encumbrances, if any, which singly and
     in the aggregate are not substantial in amount and do not materially
     detract from the value of the property subject thereto or materially impair
     the use thereof. Sequoia does not know of any potential action by any
     party, governmental or other, and no proceedings with respect thereto have
     been instituted of which Sequoia has notice, that would materially affect
     Sequoia's ability to use and to utilize each of such assets in its business
     or in the business of its Subsidiaries. Sequoia has received no notices
     from any mortgagee regarding any properties owned by Sequoia. The Sequoia
     Disclosure Document contains a detailed listing of all assets that consist
     of (a) accounts receivable as provided in clause (xii) below, (b)
     miscellaneous current assets in excess of $25,000, (c) prepaid expenses in
     excess of $10,000 (d) real property, and (e) gross aggregate additions for
     each of the past four years, by location, of (A) buildings and
     improvements, (B) furniture and fixtures, (C) leasehold improvements, or
     (D) automobiles and trucks.

            (viii)  Proprietary Rights.  a.  Sequoia and each of its
            Subsidiaries possesses full ownership of, or adequate and
            enforceable long-term licenses or other rights to use (without
            payment), all Proprietary Rights owned by or registered in the name
            of Sequoia or any of its Subsidiaries or used in the business of
            Sequoia or any of its Subsidiaries. Set forth in the Sequoia
            Disclosure Document is a list and brief description of all
            Intellectual Property of Sequoia, and all applications for such
            which are in the process of being prepared, owned by or registered
            in the name of Sequoia, or of which Sequoia is a licensor or
            licensee or in which Sequoia has any right, and in each case a brief
            description of such right. No claim is pending or, to the best of
            Sequoia's knowledge, threatened to the effect that the operations of
            Sequoia infringe upon or conflict with the asserted rights of any
            other person under any Intellectual Property, and there is no basis
            for any

                                      I-17
<PAGE>
 
            such claim (whether or not pending or threatened). No claim is
            pending or threatened to the effect that the Proprietary Rights
            owned or licensed by Sequoia, or which Sequoia otherwise has the
            right to use, is invalid or unenforceable by Sequoia, and there is
            no basis for any such claim (whether or not pending or threatened).
            All prior art known to Sequoia which may or be or may have been
            pertinent to the examination of any United States patent or patent
            application listed in the Sequoia Disclosure Document has been cited
            to the United States Patent and Trademark Office. To the best of
            Sequoia's knowledge, all technical information developed by and
            belonging to Sequoia which has not been patented has been kept
            confidential. Sequoia has not granted or assigned to any other
            person or entity any right to manufacture, have manufactured,
            assemble or sell the services of Sequoia.

                    b.  To the best of Sequoia's knowledge, no third party has
            claimed or has reason to claim that any person employed by or
            affiliated with Sequoia has: (1) violated or may be violating any of
            the terms or conditions of his employment, non-competition or non-
            disclosure agreement with such third party, (2) disclosed or may be
            disclosing or utilized or may be utilizing any trade secret or
            proprietary information or documentation of such third party or (3)
            interfered or may be interfering in the employment relationship
            between such third party and any of its present or former employees.
            No third party has requested information from Sequoia which suggests
            that such a claim might be contemplated. To the best of Sequoia's
            knowledge, no person employed by or affiliated with Sequoia has
            employed or proposes to employ any trade secret or any information
            or documentation proprietary to any former employer, and to the best
            of Sequoia's knowledge, no person employed by or affiliated with
            Sequoia has violated any confidential relationship which such person
            may have had with any third party, in connection with the
            development, manufacture or sale of any proposed service of Sequoia
            and Sequoia has no reason to believe there will be any such
            employment or violation. To the best of Sequoia's knowledge, neither
            the execution or delivery of this Agreement, nor the carrying on of
            the business of Sequoia as officers, employees or agents by any
            officer, director or key employee of Sequoia, nor the conduct or
            proposed conduct of the business of Sequoia, will conflict with or
            result in a breach of the terms, conditions or provisions of or
            constitute a default under any contract, covenant or instrument
            under which any such person is obligated.

            (ix)    Subsidiaries, Etc.  Except as set forth in the Sequoia
     Disclosure Document, Sequoia has no Subsidiaries, and neither Sequoia nor
     any of its Subsidiaries described in the Sequoia Disclosure Document is a
     partner of or joint venturer with any other person or Entity. All of the
     issued and outstanding shares of capital stock of each Subsidiary are owned
     of record and beneficially by Sequoia or another Subsidiary of Sequoia, are
     validly issued, fully paid and nonassessable and are owned free and clear
     of all liens, charges, claims, pledges, security interests, equities,
     encumbrances, reservations or contractual restrictions on transfer of any
     nature whatsoever; and no Subsidiary has outstanding any securities,
     warrants, options or other rights convertible

                                      I-18
<PAGE>
 
     into or exchangeable or exercisable for any shares of its capital stock,
     and there are no contracts, commitments, understandings, arrangements or
     restrictions by which any Subsidiary is bound to issue shares of its
     capital stock.

            (x)     Employee Benefit Plans.  Neither Sequoia nor any Entity
     required to be aggregated with Sequoia under Sections 414(b), (c), (m) or
     (n) of the Code sponsors, maintains, has any obligation to contribute to,
     has any liability under, or is otherwise a party to, any Benefit Plan. With
     respect to each Benefit Plan in the Sequoia Disclosure Document, to the
     extent applicable:

                    (a)  Each such Benefit Plan has been maintained and operated
            in all material respects in compliance with its terms and with all
            applicable provisions of ERISA, the Code and all regulations,
            rulings and other authority issued thereunder;

                    (b)  All contributions required by law to have been made
            under each such Benefit Plan (without regard to any waivers granted
            under Section 412 of the Code) to any fund or trust established
            thereunder or in connection therewith have been made by the due date
            thereof;

                    (c)  Each such Benefit Plan intended to qualify under
            Section 401(a) of the Code is the subject of a favorable unrevoked
            determination letter issued by the Internal Revenue Service as to
            its qualified status under the Code, which determination letter may
            still be relied upon as to such tax qualified status, and no
            circumstances have occurred that would adversely affect the tax
            qualified status of any such Benefit Plan;

                    (d)  The actuarial present value of all accrued benefits
            under each such Benefit Plan subject to Title IV of ERISA did not,
            as of the latest valuation date of such Benefit Plan, exceed the
            then current value of the assets of such Benefit Plan allocable to
            such benefits, all as based upon the actuarial assumptions and
            methods currently used for such Benefit Plan;

                    (e)  None of such Benefit Plans that are "employee welfare
            benefit plans" as defined in Section 3(1) of ERISA provides for
            continuing benefits or coverage for any participant or beneficiary
            of a participant after such participant's termination of employment;
            and

                    (f)  Neither Sequoia nor any trade or business (whether not
            incorporated) under common control with Sequoia within the meaning
            of Section 401 of ERISA has, or at any time has had, any obligation
            to contribute to any "multiemployer plan" as defined in Section
            3(37) of ERISA.

            (xi)    Facilities.  Sequoia Facilities are (as to physical plant
     and structure) structurally sound and none of Sequoia Facilities, nor any
     of the vehicles or other equipment used by Sequoia in connection with its
     business, has any material defects and

                                      I-19
<PAGE>
 
     all of them are in all material respects in good operating condition and
     repair and are adequate for the uses to which they are being put; none of
     such Sequoia Facilities, vehicles or other equipment is in need of
     maintenance or repairs except for ordinary, routine maintenance and repairs
     which are not material in nature or cost.  Sequoia is not in breach,
     violation or default of any lease with respect to or as a result of which
     the other party (whether lessor, lessee, sublessor or sublessee) thereto
     has the right to terminate the same, and Sequoia has not received notice of
     any claim or assertion that it is or may be in any such breach, violation
     or default.

            (xii)   Accounts Receivable.  All accounts receivable of Sequoia and
     each Subsidiary, whether reflected in the Sequoia Balance Sheet or
     otherwise, represent transactions in the ordinary course of business, and
     are current and collectible net of any reserves shown on such Balance Sheet
     (which reserves are adequate and were calculated consistent with past
     practice). The Sequoia Disclosure Document specifically identifies (a) the
     aging of Receivables, (b) each Receivable in excess of $10,000, (c) each
     Receivable in an amount in excess of $1,000 that is more than 90 days past
     due, and (d) each receivable from a person or Entity from whom the
     aggregate of such Receivables exceeds $25,000.

            (xiii)  Inventories.  All Inventories of Sequoia and its
     Subsidiaries reflected in the Sequoia Balance Sheet, are of a quality and
     quantity usable and salable in the ordinary course of business, except for
     obsolete items and items of below-standard quality, all of which are in the
     aggregate immaterial to the business, financial condition, results of
     operations or prospects of Sequoia. Items included in such Inventories are
     carried on the books of Sequoia, and are valued on the Sequoia Balance
     Sheet, at the lower of cost or market and, in any event, at not greater
     than their net realizable value, on an item by item basis, after
     appropriate deduction for costs of completion, marketing costs,
     transportation expense and allocation of overhead.

            (xiv)   Contracts.  Except as identified in the Sequoia Disclosure
     Document, Sequoia has no contracts, agreements or understandings, written
     or verbal, provided however, that Sequoia may have, and the Sequoia
     Disclosure Document need not identify, any such contracts, agreements or
     understandings that fall into one of the following categories:  (a) those
     that are terminable on notice of less than 32 days and do not involve
     payments or obligations of more than $1,000 in any period of 31 days or
     less (on termination or otherwise); or (b) those that involve aggregate
     payments or obligations of less than $5,000.  The Sequoia Disclosure
     Document shall, however, identify each contract otherwise exempt from
     disclosure by (b) above if Sequoia's obligations, in the aggregate, under
     all such contracts, agreements or understandings with persons or entities
     similarly situated (e.g., all non-union employees, all suppliers, all
     licensees, all landlords, etc.) exceeds $25,000 per annum.  The Sequoia
     Disclosure Document includes a brief summary of each such contract,
     agreement or understanding identified therein, or of the type of such
     contracts and the aggregate exposure or commitment under similar contracts
     in the case of contracts included by reason of the preceding sentence.
     Without in any respect limiting the foregoing, the Sequoia

                                      I-20
<PAGE>
 
     Disclosure Document contains a description of all leases of properties by
     Sequoia, including all amendments, supplements, extensions and
     modifications thereof, identifying, inter alia, the date each such document
     was executed and its effective period.  Sequoia is not a party to any
     executory contract to sell or transfer any part of any leasehold interest
     of Sequoia other than this Agreement.  True and accurate copies of all
     leases, and of all amendments, supplements, extensions and modifications
     thereof, have heretofore been delivered to SAC by Sequoia.

            (xv)    Accounts Payable.  The accounts payable reflected on the
     Sequoia Balance Sheet will, and those reflected in the most recent balance
     sheet included in the Unaudited Financial Statements do, and those
     reflected on the books of Sequoia at the time of the Closing will, reflect
     all amounts owed by Sequoia in respect of trade accounts due and other
     short-term liabilities commonly identified as accounts payable, and the
     actual Liability of Sequoia in respect of such obligations was not, and
     will not be, on any of such dates, in excess of the amounts so reflected on
     the balance sheets or the books of Sequoia, as the case may be.

            (xvi)   Labor Matters.  Except as set forth in the Sequoia
     Disclosure Document, there are no activities or controversies, including,
     without limitation, any labor organizing activities, election petitions or
     proceedings, proceedings preparatory thereto, unfair labor practice
     complaints, labor strikes, disputes, slowdowns or work stoppages, pending
     or, to the best of the knowledge of Sequoia, threatened, between Sequoia or
     any of its Subsidiaries and any of its or their employees.

            (xvii)  Insurance.  Sequoia and its Subsidiaries have insurance
     policies in full force and effect which provide for coverages which are
     usual and customary in the business of Sequoia and its Subsidiaries as to
     amount and scope, and are adequate to protect Sequoia against any
     reasonably foreseeable risk of loss, including business interruption.  The
     Sequoia Disclosure Document identifies each of Sequoia's insurance
     policies, indicating the carrier, amount of coverage, annual premium, risks
     covered, placing broker or agent and other relevant information as to each.
     Sequoia has not within the past three (3) years received any notice of
     cancellation of any insurance agreement.

            (xviii) Title to and Utilization of Real Properties.  Except as
     disclosed in the Sequoia Disclosure Document, Sequoia owns fee simple,
     insured title to all real property identified therein or in any document
     referred to herein as owned by Sequoia and, has unbridled right to use the
     same, and is not aware of any claim, notice or threat to the effect that
     its right to own and use such property is subject in any way to any
     challenge, claim, assertion of rights, proceedings toward condemnation or
     confiscation in whole or in part, or is otherwise subject to challenge.

            (xix)   Foreign Corrupt Practices Act.  Sequoia has not taken any
     action which would cause it to be in violation of the Foreign Corrupt
     Practices Act of 1977, as amended, or any rules and regulations thereunder.
     To the best of Sequoia knowledge

                                      I-21
<PAGE>
 
     after due inquiry, there is not now, and there has never been, any
     employment by Sequoia of, or beneficial ownership in Sequoia by, any
     governmental or political official in any country in the world.

     5.08.  FULL DISCLOSURE.  The documents, certificates and other writings
furnished or to be furnished by or on behalf of Sequoia to SAC pursuant to the
provisions of this Agreement, taken together in the aggregate, do not and will
not contain any untrue statement of a material fact, or omit to state any
material fact necessary to make the statements made, in the light of the
circumstances under which they are made, not misleading.

     5.09.  ACTIONS SINCE BALANCE SHEET DATE.  Except as set forth on the
Sequoia Disclosure Document, from the date of this Agreement through the Closing
Date, Sequoia will have taken no actions that would be prohibited under the
provisions of this Agreement (without the prior consent of SAC).


                                  ARTICLE VI

                           COVENANTS OF TMS AND SAC

     6.01.  AFFIRMATIVE COVENANTS.  From the date hereof through the Closing
Date, each of TMS and SAC will take every action reasonably required of it in
order to ensure the prompt and expedient consummation of the Merger
substantially as contemplated hereby, and will exert all reasonable efforts to
cause the same to be consummated, provided in all instances that the
representations and warranties of the Company and the Seller herein are and
remain true and accurate and that the covenants and agreements of Sequoia and of
the Seller herein are honored.

     6.02.  COOPERATION.  TMS and SAC shall cooperate with Sequoia and the
Seller and their counsel, accountants and agents in every way in carrying out
the transactions contemplated herein, and in delivering all documents and
instruments deemed reasonably necessary or useful by Counsel to Sequoia.

     6.03.  EXPENSES.  Whether or not the Merger is consummated, all costs and
expenses incurred by TMS and SAC in connection with this Agreement and the
Mergers contemplated hereby shall be borne by them.

     6.04.  PUBLICITY.  Prior to the Closing any written news releases by TMS
and SAC pertaining to this Agreement or the Merger shall be reviewed and
approved prior to release by Sequoia, provided, however, that such review and
approval shall not be required of releases by TMS and SAC if prior review and
approval would prevent the timely and accurate dissemination of such press
release as required to comply, in the judgment of counsel, with any applicable
law, rule or policy.

     6.05.  UPDATING OF EXHIBITS AND DISCLOSURE DOCUMENTS.  TMS and SAC shall
notify Sequoia of any changes, additions or events which may cause any change in
or addition to any

                                      I-22
<PAGE>
 
Schedules or Exhibits delivered by it under this Agreement, promptly after the
occurrence of the same and at the Closing by the delivery of updates of all
Schedules and Exhibits.  No notification made pursuant to this Section shall be
deemed to cure any breach of any representation or warranty made in this
Agreement unless Sequoia specifically agrees thereto in writing nor shall any
such notification be considered to constitute or give rise to a waiver by
Sequoia of any condition set forth in this Agreement.

     6.06.  REGISTRATION.  TMS agrees that promptly following the execution
hereof, it will commence preparation of a registration statement on Form S-4 (or
such other form as may be appropriate) under the Securities Act, and will
otherwise proceed promptly to satisfy the requirements of the Securities Act
with respect to the Merger, including those of Rule 145 if applicable.  TMS
represents that, insofar as the information contained in the same relates to TMS
(including information incorporated therein by reference), the Prospectus
contained in said registration statement will (A) comply as to form with the
relevant requirements of the form on which it is filed and (B) not contain, as
of the effective date thereof, any untrue statement of a material fact or any
omission to state a material fact necessary to make the statements contained
therein, in light of the circumstances under which they are made, not
misleading.  TMS further agrees that it will, within ninety days of the Closing
of the Merger, file a Registration Statement of Form S-8 (or such other form as
may be appropriate) under the Securities Act, covering the issuance of TMS
Common Stock upon the exercise of Vested Rights and Non-Vested Rights that are
held by employees of Sequoia.


                                  ARTICLE VII

                    COVENANTS OF THE SELLER AND OF SEQUOIA

     7.01.  AFFIRMATIVE COVENANTS.  From the date hereof through the Closing
Date, Sequoia and the Seller will take every action reasonably required of each
of them in order to ensure the prompt and expedient consummation of the Merger
substantially as contemplated hereby, and will exert all reasonable efforts to
cause the same to be consummated.

     7.02.  EMPLOYMENT CONTRACTS.  Pending the Closing, and effective upon the
consummation of the Merger, Sequoia will exert its best efforts to execute
three-year employment contracts with each of the persons identified on Schedule
7.02, at an annual salary equal to that set forth for such individual in such
Schedule, in the form of Exhibit 7.02.  Sequoia will also execute a non-
competition agreement with Dana R. Allen, Seller hereunder, the provisions of
which will preclude such of the Seller from engaging in business competitive
with that of Sequoia, directly or indirectly, alone or in collaboration with
others, except with the written consent of SAC or as a shareholder of less than
1% of the common stock of a publicly-held company engaged in one or more of such
businesses, which agreement of such Seller agrees to execute.

     7.03.  NAME.  The Seller agrees that following consummation of the Merger
he shall make no attempt to make any use of the name "Sequoia Data Corporation,"
"Sequoia Computer Corporation" or any name utilizing the word "Sequoia" in
conjunction with operations in any

                                      I-23
<PAGE>
 
respect in competition with those of Sequoia as its business was conducted prior
to the Closing, or authorize others to do so, without the consent of TMS.

     7.04.  ACCESS AND INFORMATION.  Sequoia shall afford to SAC and its
accountants, counsel and other representatives reasonable access during normal
business hours throughout the period prior to the Closing to all of its and its
Subsidiaries properties, books, contracts, commitments, records (including, but
not limited to, tax returns) and personnel and, during such period, Sequoia
shall furnish promptly to SAC (i) all written communications to its directors or
to its shareholders generally, (ii) internal monthly financial statements when
and as available, and (iii) all other information concerning its or any of its
subsidiaries' business, properties and personnel as SAC may reasonably request,
but no investigation pursuant to this Section 7.04 shall affect any
representations or warranties of Sequoia, or the conditions to the obligations
of SAC to consummate the Merger contained in this Agreement.  In the event of
the termination of this Agreement, SAC will, and will cause its representatives
to, deliver to Sequoia or destroy all documents, work papers and other material,
and all copies thereof, obtained by it or on its behalf from Sequoia (or any
subsidiary) as a result of this Agreement or in connection herewith, whether so
obtained before or after the execution hereof, and will hold in confidence all
confidential information that has been designated as such by Sequoia in writing
or by appropriate and obvious notation, and will not use any such confidential
information except in connection with the Merger, until such time as such
information is otherwise publicly available.  TMS and its representatives shall
assert their rights hereunder in such manner as to minimize interference with
the business of Sequoia.

     7.05.  NO SOLICITATION.  Sequoia and its respective Subsidiaries, the
Seller and those acting on behalf of any of them will not, and Sequoia will use
its best efforts to cause its officers, employees, agents and representatives
(including any investment banker) to not, directly or indirectly, solicit,
encourage or initiate any discussions with, or negotiate or otherwise deal with,
or provide any information to, any person or Entity other than TMS, SAC and
their respective officers, employees and agents, concerning any merger, sale of
substantial assets or similar transaction involving Sequoia or any subsidiary or
division of Sequoia or any sale of any of its capital stock or of any subsidiary
or division.  Sequoia will notify SAC immediately upon receipt of any inquiry,
offer or proposal relating to any of the foregoing.  None of the foregoing shall
prohibit providing information to others in a manner in keeping with the
ordinary conduct of Sequoia's business, or providing information to government
authorities.

     7.06.  CONDUCT OF BUSINESS PENDING THE MERGER.  Sequoia and the Seller
covenant and agree, severally and jointly, with TMS that, prior to the
consummation of the Merger or the termination of this Agreement pursuant to its
terms, unless TMS shall otherwise consent in writing, which consent shall not be
unreasonably withheld or delayed, and except as otherwise contemplated by this
Agreement or disclosed in the Sequoia Disclosure Document, Sequoia will comply
with each of the following:

            (a)  its business and the business of its Subsidiaries shall be
     conducted only in the ordinary and usual course, it shall use reasonable
     efforts and shall cause each of its Subsidiaries to use reasonable efforts
     to keep intact its and

                                      I-24
<PAGE>
 
     their business organizations and good will, keep available the services of
     their respective officers and employees and maintain good relationships
     with suppli ers, lenders, creditors, distributors, employees, customers and
     others having business or financial relationships with them, and it shall
     immediately notify SAC of any event or occurrence or emergency material to,
     and not in the ordinary and usual course of business of, it or any of its
     Subsidiaries;

            (b)  it shall not (i) amend its Articles of Incorporation or By-Laws

time prior to the Closing, whether before or after any approval by shareholders:

     provided in Section 8.02, cannot reasonably be satisfied on or before

Shareholders. This Agreement may not be amended except by an instrument in
writing signed on behalf of Sequoia and SAC. By executing this Agreement, the

this Agreement approved by Sequoia to the limited extent set forth in this
Section 10.02

hereto, (b) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto or (c) waive

party.

     10.04. RELIEF.  In the event of liability on the part of any party in
accordance with the provisions of this Agreement, the parties recognize and
acknowledge that monetary measures of damages will not reasonably be calculable
and that specific performance and injunctive relief should therefore be
available to the other party.

Provisions of the California Corporations Code governing dissenters' rights.
     
     (S)  1300.  REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES;
                 CORPORATE PURCHASE AT FAIR MARKET VALUE; DEFINITIONS
    
     (a)  If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b).  The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.      

     (b)  As used in this chapter, "dissenting shares" means share which come
within all of the following descriptions:
    
     (1)  Which were not immediately prior to the reorganization or short-form
merger either (A) listed on any national securities exchange certified by the
Commissioner of Corporations under subdivision (o) of Section 25100 or (B)
listed on the list of OTC margin stocks issued by the Board of Governors of the
Federal Reserve System, and the notice of meeting of shareholders to act upon
the reorganization summarizes this section and Sections 1301, 1302, 1303 and
1304; provided, however, that this provision does not apply to any shares with
respect to which there exists any restriction on transfer imposed by the
corporation or by any law or regulation; and provided, further, that this
provision does not apply to any class of shares described in * * * subparagraph
(A) or (B) if demands for payment are filed with respect to 5 percent or more of
the outstanding shares of that class.      

     (2)  Which were outstanding on the date for the determination of
shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the reorganization or, (B) if described in * * * subparagraph (A) or
(B) of paragraph (1) (without regard to the provisos in that paragraph), were
voted against the reorganization, or which were held of record on the effective
date of a short-form merger; provided, however, that * * * subparagraph (A)
rather than * * * subparagraph (B) of this paragraph applies in any case where
the approval required by Section 1201 is sought by written consent rather than
at a meeting.

     (3)  Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

     (4)  Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

     (c)  As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.
    
     (S)  1301.  NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS;
                 DEMAND FOR PURCHASE; TIME; CONTENTS      

     (a)  If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date

                                      II-1
<PAGE>
 
of such approval, accompanied by a copy of Sections 1300, 1302, 1303, 1304 and
this section, a statement of the price determined by the corporation to
represent the fair market value of the dissenting shares, and a brief
description of the procedure to be followed if the shareholder desires to
exercise the shareholder's right under such sections.  The statement of price
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.

     (b)  Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value.  The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

     (c)  The demand shall state the number and class of shares held of record
by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
    
     (S)  1302.  SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT;
                 UNCERTIFICATED SECURITIES      
    
     Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase.  Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.      

     (S) 1303.   PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR
                 MARKET VALUE; FILING; TIME OF PAYMENT
    
     (a)  If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement.  Any agreements fixing the
fair market value of any dissenting shares as between the corporation and the
holders thereof shall be filed with the secretary of the corporation.      

     (b)  Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of

                                      II-2
<PAGE>
 
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

     (S)  1304.  ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR
                 FAIR MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATION;
                 DETERMINATION OF ISSUES; APPOINTMENT OF APPRAISERS

     (a)  If the corporation denies that the shares are dissenting shares, or
the corporation and the shareholder fail to agree upon the fair market value of
the shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

     (b)  Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

     (c)  On the trial of the action, the court shall determine the issues.  If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue.  If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

     (S) 1305.   REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT;
                 JUDGMENT; PAYMENT; APPEAL; COSTS

     (a)  If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share.  Within the time fixed
by the court, the appraisers, or a majority of them, shall make and file a
report in the office of the clerk of the court.  Thereupon, on the motion of any
party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant.  If the court finds the report
reasonable, the court may confirm it.

     (b)  If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.
    
     (c)  Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment is entered.     

     (d)  Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment.  Any party may appeal from the judgment.

     (e)  The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of

                                      II-3
<PAGE>
 
compliance with Sections 1300, 1301 and 1302 if the value awarded by the court
for the shares is more than 125 percent of the price offered by the corporation
under subdivision (a) of Section 1301).

     (S) 1306.   PREVENTION OF IMMEDIATE PAYMENT; STATUS AS CREDITORS; INTEREST

     To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

     (S) 1307.   DIVIDENDS ON DISSENTING SHARES

     Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

     (S) 1308.   RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION; WITHDRAWAL
                 OF DEMAND FOR PAYMENT

     Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined.  A
dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto.

     (S) 1309.   TERMINATION OF DISSENTING SHARE AND SHAREHOLDER STATUS

     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

     (a)  The corporation abandons the reorganization.  Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

     (b)  The shares are transferred prior to their submission for endorsement
in accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

     (c)  The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d)  The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

                                      II-4
<PAGE>
 
     (S) 1310.   SUSPENSION OF RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS;
                 LITIGATION OF SHAREHOLDERS' APPROVAL

     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.


     (S) 1311.   EXEMPT SHARES

     This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

     (S) 1312.   RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND
                 MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION;
                 CONDITIONS
    
     (a)  No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have right
at law or in equity to attack the validity of the reorganization or short-form
merger, or to have the reorganization or short-form merger set aside or
rescinded, except in any action to test whether the number of shares required to
authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.      
    
     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.    
    
     (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

                    INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Oklahoma General Corporation Act grants every corporation the power to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending, or completed action, suit, or proceeding, whether
civil, criminal, administrative, or investigative (other than by action by or in
the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines, and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit, or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

     The Oklahoma statute also grants every corporation the power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee, or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee, or
agent of another corporation, partnership, joint venture, trust, or other
enterprise against expenses, including attorneys' fees, actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation, except that no
indemnification shall be made in respect of any claim, issue, or matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the corporation unless and only to
the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.

     The Oklahoma statute provides that to the extent that a director, officer,
employee, or agent of a corporation has been successful on the merits or
otherwise in defense of any action, suit, or proceeding referred to in the
statute, or in defense of any claim, issue, or matter therein, he shall be
indemnified against expenses, including attorneys' fees, actually incurred by
him in connection therewith.

     Articles Nine and Ten of the Registrant's Certificate of Incorporation
indemnify and exculpate the directors, officers, employees, and agents of the
Registrant from and against certain liabilities.  Article Nine provides that the
Registrant shall indemnify to the full extent permitted under the Oklahoma
General Corporation Act any director, officer, employee, or agent of the
Registrant.  Article Ten provides that a director of the Registrant shall have
no personal liability

                                      II-1
<PAGE>
 
to the Registrant or its shareholders for monetary damages for breach of
fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to the Registrant or its shareholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) for acts or omissions specified in Section 1053 of
the Oklahoma General Corporation Act regarding the unlawful payment of dividends
and the unlawful purchase or redemption of the Registrant's stock, and (d) for
any transaction from which the director derived an improper personal benefit.

ITEM 22.  UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 22, above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable.  In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted against the registrant by such director, officer
or controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

     The undersigned registrant hereby undertakes that for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange

                                      II-3
<PAGE>
 
Act of 1934) that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to

     the effective date of the registration statement (or the most recent post-

          (iii) To include any material information with respect to the plan of 
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new 
registration statement relating to the securities offered therein, and the 
offering of such securities at that time shall be deemed to be the initial bona 
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any 
of the securities being registered which remain unsold at the termination of 
the offering.
