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.

     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
December __, 1995, 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 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.

     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
and other shareholders have either agreed in the Merger Agreement, or have
granted proxies, to vote all of our shares in favor of the approval of the
Merger Agreement.

     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 which accompanies this letter.

                                        Very truly yours,



                                        Dana R. Allen
                                        Chairman of the Board
                                             of Directors

and any and all adjournments or postponements thereof.

     The Board of Directors is not currently aware of any other business to come

Prospectus and Exhibit II thereto.

                                      The Merger Agreement is attached hereto as

                                      majority of the outstanding shares of
                                      Sequoia Stock will be required to approve

                                      to TMS, to vote all of their shares in

                                      agreement and proxies.

 The Merger; Merger Consideration:    Upon consummation of the Merger, SAC will
                                      be merged with and into Sequoia and
                                      Sequoia will become a wholly-owned
                                      subsidiary of TMS. In the Merger, each
                                      share of Sequoia Stock issued and
                                      outstanding immediately prior to the
                                      Merger (other than shares held by any
                                      shareholder who shall have perfected his
                                      or her right to dissent under the
                                      California Corporation Code) will be
                                      converted into 2.837 shares of common
                                      stock, $.05 par value, of TMS (the "TMS
                                      Common Stock").

 Determination and                    The Board of Directors of the Company on
   Recommendation of                  November 6, 1995, determined that the
   Directors:                         terms of the Merger Agreement, including
                                      the Merger Consideration to be received by
                                      the Sequoia shareholders, were 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
    of the Merger:                    Merger Agreement, the 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
    Exchange of Certificates:         the Effective Date (other than shares held
                                      of record by Dissenting Shareholders) will
                                      be converted into the right to receive
                                      2.837 shares of TMS Common Stock.
 
 Surrender of Certificates:           Promptly after the Effective Date, a
                                      letter of transmittal with instructions
                                      will be mailed to all holders of record of
                                      Sequoia Stock at the close of business on
                                      the Effective Date of the Merger for use
                                      in surrendering their certificates
                                      representing Sequoia Stock. Certificates
                                      should not be surrendered until the letter
                                      of transmittal is received and completed.

 Tax Consequences                     The Merger is intended to qualify as a 
    to Shareholders:                  tax-free reorganization within the 
                                      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 adviser 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."

    Shareholders:                     in favor of the Merger Agreement may

                                 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 TMS competitors or potential competitors 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; No Current Listing on Stock Exchange.
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. TMS is not currently eligible for inclusion on the
NASDAQ Stock 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.
Therefore, there is no assurance that TMS will qualify for inclusion on the
NASDAQ Stock Market or that a liquid trading market in TMS Common Stock will
develop. 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.

     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 TMS 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

                                      -9-
<PAGE>
 
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 TMS's
competitors 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 TMS's
products 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 TMS's
technology violates its patents in the future. As the number of software
products in the industry increases and the functionality of these products
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 the company, 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 the company.

     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 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

                                      -10-
<PAGE>
 
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 operation 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

     The Merger shall be consummated by the filing a Certificate of Merger with

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 Effective Date (other than
shares held by Dissenting Shareholders) will be converted into the right to
receive 2.837 shares of TMS Common Stock, upon the surrender of the certificate
formerly representing such share of Sequoia Stock; and (ii) each outstanding
share of SAC's common stock will be converted into one share of Sequoia Stock.

     Upon the Effective Date of the Merger, options to purchase Sequoia Stock
will be converted to entitle the holders thereof to purchase 2.837 shares of TMS
Common Stock for each share of Sequoia Stock purchasable under such options at
an exercise price equal to 35.24% of the exercise price under such options.

     Shareholders of the Company holding greater than 59% of the Sequoia Stock
outstanding on the Record Date have agreed to vote or have granted proxies to
TMS to vote, their shares of Sequoia Stock in favor of the Merger Agreement, and
therefore sufficient voting power to approve the Merger Agreement without the
affirmative vote of any of the other shareholders of the Company has been
provided for in the Merger Agreement.

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

     The Merger Agreement may be amended, by actions taken by or on behalf of
the Board of Directors of the Company and TMS at any time before the Effective

                              GENERAL INFORMATION

VOTE REQUIRED

     Approval of the Merger Agreement requires the affirmative vote of the

     Approval of the Merger Agreement by the shareholders of TMS is not

the sole shareholder of SAC, have approved the Merger and the Merger Agreement.

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 the 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 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 on 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.

FRACTIONAL SHARES

     No certificates representing fractional shares will be issued by TMS in
respect of TMS Common Shares 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 securities laws in connection with, the
issuance of such shares.

ACCOUNTING TREATMENT

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

                           BACKGROUND OF THE MERGER

RECOMMENDATION OF SEQUOIA'S BOARD OF DIRECTORS

     THE BOARD OF DIRECTORS OF SEQUOIA BELIEVE THAT THE MERGER IS IN THE BEST
INTERESTS 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 Directors of Sequoia (the "Board") believes the Merger is fair from a
financial point of view and that the Merger and the other transactions
contemplated in connection with the Merger are in the best interest of both
Sequoia and its shareholders. The Board believes Sequoia and TMS will benefit
from the Merger by

                                      -15-
<PAGE>
 
combining operations and by establishing a larger organization and revenue base
to attract customers requiring more substantial resources than either company
fields alone. It is expected that the synergies resulting from the Merger will
enhance the ability of the combined companies to compete in the competitive
document imaging software market. In addition, the Board believes that the
Merger will provide Sequoia shareholders with a route to liquidity for their
investment in Sequoia. THEREFORE, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT SEQUOIA SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER.

SEQUOIA'S REASONS FOR THE MERGER

     The Board of Directors of Sequoia has unanimously determined that the
Merger is advisable and in the best interest of Sequoia and its shareholders. In
making this determination, the Board of Directors considered a variety of
factors, including: benefit from the Merger by combining operations and by
establishing a larger organization and revenue base to attract customers
requiring more substantial resources than either company fields alone; the
Merger Consideration in relation to the present fair market value of Sequoia
Stock, the current value of Sequoia or Sequoia Stock in a negotiated transaction
and in relation to the Board's estimate of the future value of Sequoia as an
independent entity based upon Sequoia's historical and projected results of
operations; Sequoia's current financial and capital position and current and
projected cash flows; the replacement value, tangible book value and going
concern value of Sequoia's assets; the competitive environment for data image
conversion software companies generally; the compatibility of the respective
business and management philosophies of Sequoia and TMS, and the social, legal
and economic effects of the Merger upon the employees, suppliers, customers,
shareholders and other constituents of Sequoia, and the communities in which
Sequoia operates.

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 and Chief Executive Officer of Sequoia, will be elected
to the Board of Directors of TMS. Additionally, in considering the
recommendation of the Board of Directors of Sequoia with respect to the Merger,
Sequoia shareholders should also be aware that certain members of the Board and
officers of Sequoia have interests that may present them with potential
conflicts of interest. See "--Execution of Employment and Non-Competition
Agreements."

OFFICERS, DIRECTORS AND EMPLOYEES

     The Plan of Reorganization 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.

                                      -16-
<PAGE>
 
EXECUTION OF EMPLOYMENT AND NON-COMPETITION AGREEMENTS

     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 (3) year
employment agreement with Dana R. Allen. Under such employment contract, Sequoia
may terminate the above individual at any time for cause, or such individual may
be terminated without cause upon the payment of $__________.

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.

TMS'S 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.

EFFECTIVE DATE OF THE MERGER

     If the Merger Agreement is approved by the 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 _________,
1995.

              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 August 31, 1995 and unaudited pro forma
combined statements of operations for the years ended August 31, 1995 and 1994.
The pro forma combined balance sheet has been prepared on the basis that the
Merger occurred on August 31, 1995. The pro forma combined statements of
operations have been prepared on the basis that the Merger occurred at the
beginning of each 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)  Holders of Sequoia preferred stock converted their holdings to common stock
     at the rate of one share of common stock for one share of preferred stock
     subsequent to August 31, 1995, but prior to the Merger. Adjustments
     reflects conversion of Sequoia preferred stock.

(2)  Adjustment reflects the exchange of Sequoia common shares at August 31,
     1995 (1,214,180) and Sequoia common shares resulting from the conversion of
     the Sequoia preferred stock (70,000) for 2.837 shares of TMS common shares,
     and the resulting increase in additional paid-in-capital. At August 31,
     1995, after giving effect to the Merger, TMS would have had outstanding
     12,048,166 common shares, par value, $.05.

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

(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 their 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 1995 and 1994 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.

(6)  Merger costs estimated at approximately $80,000 to $100,000 have been
     excluded from the pro forma combined statements of operations and will be
     charged to operations in the first and second quarter of fiscal year 1996,
     as incurred. The pro forma combined balance sheet gives effect to such
     expenses as if they had been incurred as of August 31, 1995.

             CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following discussion summarizes certain federal income tax
considerations involved in exchange of Sequoia Stock for TMS Common Stock in the
Merger. 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
capital assets 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 Common Stock in cash rather than to retain
his or her shares of Sequoia 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 to be
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 the day before the first announcement of the Merger, which was
September 8, 1995. 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 thirty (30) days after the date of
the agreement or within thirty (30) days after any statutory or contractual
conditions to the Merger are satisfied, whichever is later.

                                      -22-
<PAGE>
 
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
markets 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 if the court's appraisal exceeds the price
offered, 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 dissenter's 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 October 31, 1995, Sequoia had 12 employees.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF CERTAIN RELEVANT FACTORS

     The Company's operating results have reflected certain trends. The
Company's revenues from the sales of ScanFix toolkits have declined as license
revenues have increased due to the sales of software products developed with
those toolkits. The Company believes revenues from FormFix will increase since
the product's toolkit was released in the last fiscal year.

     Gross margin (i.e., net sales less cost of sales) for fiscal 1995 was
94.5%, and the Company believes that gross margin for fiscal 1996 will decline
due to increased sales and marketing expenditures in fiscal 1996. The Company
has no data reflecting industry gross margins.

     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.

LEGAL PROCEEDINGS OF SEQUOIA

     Sequoia does not have any material pending or threatened litigation.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS OF SEQUOIA

     There have been no changes in or disagreements with the independent
accountants of Sequoia during the two most recent fiscal years or any subsequent
interim period.

MARKET FOR SEQUOIA AND DIVIDENDS

     There is no public or established private market for Sequoia Stock. No
dividends have been paid on Sequoia Stock since its incorporation.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

     Sequoia shareholders of record at the close of business on October 31,
1995, will be entitled to one vote for each share of Sequoia Common Stock then
held. As of that date, Sequoia had 1,284,180 shares of Common Stock issued and
outstanding. As of the date of this Proxy Statement -Prospectus, management of
Sequoia knows of no persons other than those listed below who are deemed to be
the beneficial owners, as such term is defined in Rule 13d-3 promulgated under
the Exchange Act, of more than 5% of the shares of Sequoia Stock.

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 are outstanding. There were
1,284,180 shares of Sequoia Stock issued and outstanding on the Record Date.

     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

                                      -26-
<PAGE>
 
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, shareholder 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 10%
of the votes at the meeting may, upon request in writing to the Chairman of the
Board, President, Vice President or Secretary of the 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.

                                      -27-
<PAGE>
 
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 (10%) 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.

                                 LEGAL MATTERS

     The validity of the TMS Common Stock offered hereby will be passed upon for
TMS by Phillips McFall McCaffrey McVay & Murrah, P.C.

                         ----------------------------


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 10 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 2 and 8 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

                           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)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Revenue Recognition

     Revenue is recognized at the time of shipment, net of allowances for
     estimated future product returns.

     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.

     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.

     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
     $26,545 and $4,270 for each of the years ended August 31, 1995 and 1994,
     respectively.

                                                                     (Continued)

                         Notes to Financial Statements

     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 enactments 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.

(3)  PROPERTY AND EQUIPMENT

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

(6)  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.

                                                                     (Continued)

(7)  RETIREMENT SAVINGS PLAN
             
     The Company has established a retirement savings plan that is available to
     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
     limitiations imposed by the Internal Revenue Service. The Company made no
     contributions to the plan for the years ended August 31, 1995 and 1994.
             
(8)  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
     of $157,768 was determined as of September 1, 1993, and is reported
     separately in the accompanying statement of earnings for the year ended
     August 31, 1994.

     Income tax expense for the years ended August 31, 1995 and 1994 consisted

     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.

                                                                     (Continued)

     The Company believes that it is more likely than not that the results of
     future operations will generate significant taxable earnings to realize the
     deferred tax asset, thus, no valuation allowance has been provided.

     statutory rate of 34% is as follows:

(9)  COMMITMENTS AND CONTINGENCIES

     The Company leases office space for its headquarters facility.  The lease
     term expires on June 1, 1996 with an option to renew for an additional 25
     months.  The minimum future commitment under this lease is approximately
     $17,000.  Rental expense amounted to approximately $22,266 and $18,840 for
     the years ended August 31, 1995 and 1994, respectively.

     In the normal course of business, the Company is from time to time involved
     in various asserted and unasserted claims.  In the opinion of management,
     the ultimate disposition of such matters will not have a material effect on
     the Company's financial position.

                                                                     (Continued)

(10) 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.

       2.01.  THE MERGER.  On the Closing Date, and at the Closing Time, subject
in all instances to each of the terms, conditions, provisions and limitations
contained in this Agreement, SAC will merge with and into Sequoia, by the
filing: (a) with the Secretary of State of the State of Oklahoma of a fully
executed Certificate of Merger in the form attached hereto as Exhibit 2.01(a) in
all material respects, and (b) with the Secretary of State of the State of

                                      I-6
<PAGE>
 
material respects, and (iii) a copy of this Agreement. As described in said
Exhibits, upon the occurrence of the Merger, (i) Sequoia shall be the Surviving
Corporation; (ii) each share of Sequoia Common Stock 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 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 and directors of SAC will
be the officers and directors of the Surviving Corporation; (v) Sequoia, the
Surviving Corporation, as such, shall be the owner of all of the business,
assets, rights and other attributes theretofore held by either SAC or Sequoia;
(vi) the separate existence of SAC shall cease; (vii) the name of the Surviving
Corporation shall thereafter be "Sequoia Data Corporation"; (viii) the Articles
of Incorporation and Bylaws of Sequoia in effect at the Closing Time shall

(ix) Sequoia shall become a wholly-owned subsidiary of TMS.

       2.02.  CONSIDERATION.  Pursuant to the Merger each Sequoia Shareholder
shall be entitled to receive at the Closing, in respect of each share of Sequoia
Common Stock outstanding immediately prior to the Merger owned by such Sequoia
Shareholder (and upon surrender of the certificate therefor, duly endorsed and
in all respects in proper form for transfer), the Consideration, to be payable
as provided in Article III.

       2.03.  CLOSING.  The closing hereunder shall take place at the offices of

Merger. If, after such consummation, such a provision requires amendment,
modification, interpretation, etc., the same may be accomplished by (but only
by) a majority in interest of those receiving the Consideration as a result of
the Merger, and not by Sequoia, if Sequoia comes to be Controlled by TMS as a
result of the Merger.


                                  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:

                                      I-7
<PAGE>
 
              (a)  At the Closing Time:

                   (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

                                      I-8
<PAGE>
 
certificates representing TMS Common Stock until such persons surrender their
certificates which prior to the Closing Date represented Sequoia Common Stock.
Upon such 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
value of such Sequoia Common Stock if the Merger is effected, and if such
Sequoia Shareholders take all other action required in the manner provided in
Section 1300 et seq. of the California Corporation Law. Such holders shall be
entitled to payment for such Sequoia Common Stock in accordance with the
provisions of Section 1300 et seq. of the California Corporation Law if
applicable.

       3.05.  NON-DILUTION.  In the event that, at any time after the date
hereof and prior to the Effective Date, TMS shall effect (a) a dividend upon TMS
Common Stock payable in TMS Common Stock or in the common stock, preferred stock
or other securities of TMS or any affiliated corporation, (b) a split or
combination of outstanding TMS Common Stock into a greater or smaller number of
TMS Common Stock, or (c) any reorganization or reclassification of TMS Common
Stock, or any liquidation, or any consolidation or merger with another
corporation, or the sale of all or substantially all of its assets to another
person (collectively, any "Organic Change"), in such a way that holders of
outstanding TMS Common Stock shall be entitled to receive (either directly, or
upon subsequent liquidation) cash, stock, securities, or other property with
respect to or in exchange for such TMS Common Stock, then, as a condition of
provisions shall be made whereby the Sequoia Shareholders immediately prior to
the Effective Date, other than holders of Dissenting Shares ("Sequoia
Shareholders") shall be entitled, under the same terms otherwise applicable to
their receipt of the TMS Common Stock in the Merger,

                                      I-9
<PAGE>
 
to become entitled to receive on the Effective Date, in lieu thereof or in
addition to the TMS Common Stock to which such Sequoia Shareholders are entitled
immediately prior to such dividend, split, combination or Organic Change, such
cash, stock, securities, or other property which Sequoia Shareholders would have
owned or been entitled to receive if the Sequoia Shareholders had owned the TMS
Common Stock, immediately prior to the happening of such event or the record
date therefor, and in any such case appropriate provisions shall also be made
with respect to Sequoia Shareholders' rights and interests to the end that the
provisions of this Section 3.05 shall thereafter be applicable in relation to
any stock, securities, or other property thereafter payable or deliverable to
Sequoia Shareholders pursuant to the earlier application of the provisions of
this Section 3.05.

Agreement or the Merger or any related transaction based upon any agreements,

       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.

       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 of TMS,
all technical

                                     I-12
<PAGE>
 
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.

       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.

                       REPRESENTATIONS AND WARRANTIES OF

authority having jurisdiction, or cause the suspension or revocation of any
authorization, consent, approval or license, presently in effect, which affects
or binds the Seller, Sequoia or any of its Subsidiaries or any of its or their

of Sequoia and its Subsidiaries, taken as a whole, and will not have a material
adverse effect on the validity of this Agreement or on the validity of the
consummation of the Merger, (iii) conflict with or result in a material breach

       5.06.  FINANCIAL STATEMENTS. Sequoia has heretofore delivered to SAC the
Audited Financial Statements of Sequoia. All of the historical financial
statements contained in the Audited Financial Statements were prepared from the
books and records of Sequoia, were prepared in accordance with GAAP, and fairly
and accurately reflect the financial position and condition of Sequoia as at the
dates and for the periods indicated. Without limiting the foregoing, at the date

assets in the Sequoia Balance Sheet shall not be more than their fair saleable
value (on an item by item basis) at that date; and Sequoia shall have had no
Liabilities, other than those included in the Sequoia Balance Sheet or in
amounts in excess of those included for such liabilities in the Sequoia Balance

prepare financial statements on the same basis that it has done so in the past,
will promptly deliver the same to SAC, and agrees that from and after such
delivery the foregoing representations will be applicable to each financial
statement so prepared and delivered.

       5.07.  ABSENCE OF MATERIAL DIFFERENCES FROM DISCLOSURE DOCUMENT. Except
as specifically disclosed in Sequoia Disclosure Document:

              (i)    No Undisclosed Liabilities. Neither Sequoia nor any of its
       Subsidiaries has any Liabilities which are not adequately reflected or
       reserved against on the face of the Sequoia Balance Sheet, except
       Liabilities incurred since the date of the Sequoia Balance Sheet in the
       ordinary course of business and consistent with past practice, without
       limiting the foregoing, (a) there are no unpaid leasehold improvements at
       any of Sequoia's facilities or locations for which Sequoia is or will be
       responsible, (b) there are no deferred rents due to lessors at or with
       respect to any of such facilities or locations, and (c) the Sequoia
       Disclosure Document sets forth, as a part thereof, each Liability of
       Sequoia, in an amount in excess of $10,000 and the aggregate amount of
       Liabilities to each person to whom such aggregate exceeds $10,000.

              (ii)   No Material Adverse Change, Etc. Since the date of the
       Sequoia Balance Sheet, other than as contemplated or caused by this
       Agreement, there has not been (a) any material adverse change in the
       operations, financial condition, assets, business, prospects or results
       of operations of Sequoia; (b) any damage, destruction or loss, whether
       covered by insurance or not, having a material adverse effect on the
       operations, financial conditions, assets, business, prospects or results
       of operations of Sequoia; (c) any entry into or termination of any
       material commitment, contract, agreement or transaction (including,
       without limitation, any material borrowing or capital expenditure or sale
       or other disposition of any material asset or assets) other than this
       Agreement and agreements executed in the ordinary course of business; (d)
       any redemption, repurchase or other acquisition for value of its capital
       stock by Sequoia, or any issuance of capital stock of Sequoia or any
       subsidiary or of securities convertible into or rights to acquire any
       such capital stock or any dividend or distribution declared, set aside or
       paid on capital stock of Sequoia; (e) any transfer of or rights granted
       under any material leases, licenses, agreements, patents, trademarks,
       tradenames or copyrights; (f) any sale or other disposition of any asset
       of Sequoia or any Subsidiary, or any mortgage, pledge or

                                     I-16
<PAGE>
 
       imposition of any lien or other encumbrance on any asset of Sequoia other
       than in the ordinary course of business, or any agreement relating to any
       of the foregoing; or (g) any default or breach by Sequoia or any
       Subsidiary in any material respect under any contract, license or permit.
       Since the date of the Sequoia Balance Sheet, Sequoia and its Subsidiaries
       have conducted their businesses only in the ordinary and usual course,
       and, without limiting the foregoing, no changes have been made in (a)
       executive compensation levels, (b) the manner in which other employees of
       Sequoia and its Subsidiaries are compensated, or (c) supplemental
       benefits provided to such employees, or (d) inventory levels in relation
       to sales levels, except, in any such case, in the ordinary course of
       business and, in any event, without material adverse effect on the
       financial condition or results of operations of Sequoia.

              (iii)  Taxes.  Sequoia and its Subsidiaries have properly filed or
       caused to be filed all federal, state, local and foreign income and other
       tax returns, reports and declarations that are required by applicable law
       to be filed by them, and have paid, or made full and adequate provision
       for the payment of, all federal, state, local and foreign income and
       other taxes properly due for the periods covered by such returns, reports
       and declarations, except such taxes, if any, as shall be adequately
       reserved against in the Sequoia Balance Sheet.

              (iv)  Litigation. (a) No material investigation or review by any
       governmental entity with respect to Sequoia or any of its Subsidiaries is
       pending or, to the best of the knowledge of Sequoia, threatened (other
       than inspections and reviews customarily made of businesses such as that
       of 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 federal, state, municipal or other governmental
       department, commission, board, bureau, agency or instrumentality. The
       Sequoia Disclosure Document includes a brief description of each
       litigation matter included therein except claims for amounts of less than
       $1,000.

              (v)  Employees, Etc. There are, except as disclosed on the Sequoia
       Disclosure Document, no collective bargaining, bonus, profit sharing,
       compensation or other plans, agreements, trusts, funds or arrangements
       maintained by Sequoia or any Subsidiary for the benefit of their
       directors, officers or employees, and there are no employment,
       consulting, severance or indemnification arrangements, agreements or
       understandings between Sequoia or any of its Subsidiaries, on the one
       hand, and any current or former directors, officers or other employees
       (or affiliates thereof of Sequoia or any of its Subsidiaries, on the
       other hand). The Sequoia Disclosure Document identifies each person whose
       income from Sequoia in the fiscal year ended on the date of Sequoia
       Balance Sheet exceeded, or whose income from Sequoia in the fiscal year
       begun immediately thereafter is at a rate exceeding, $75,000 per annum,
       and describes any contractual arrangement for the employment or
       compensation of each such person. Sequoia is not, and following the
       Closing will not be, bound by any express or implied contract or
       agreement to employ, directly or as a consultant or otherwise, any person
       for any specific period of time or until

                                     I-17
<PAGE>
 
       any specific age except as specified in agreements in writing identified
       in the Sequoia Disclosure Document or executed pursuant to the provisions
       hereof, if any.

              (vi)   Compliance With Laws. Each of Sequoia and its Subsidiaries
       is in substantial compliance with all, and has received no notice of any
       violation of any, laws or regulations applicable to its operations,
       including without limitation the use of premises occupied by it, or with
       respect to which compliance is a condition of engaging in any aspect of
       the business of Sequoia and its Subsidiaries and each has all permits,
       licenses, zoning rights and other governmental authorizations necessary
       to conduct its business as presently conducted.

              (vii)  Ownership of Assets. Each of Sequoia and its Subsidiaries
       has, except as disclosed in the Sequoia Disclosure Document, 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. 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
              such claim (whether or not pending or threatened). No claim is
              pending or threatened to the effect that

                                     I-18
<PAGE>
 
              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 documen tation 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
       into or exchangeable or exercisable for any shares of its capital stock,
       and there are no contracts, commitments, understand-

                                     I-19
<PAGE>
 
       ings, 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 "multiemp loyer 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-20
<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 oper ations 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
       Disclosure Document contains a description

                                     I-21
<PAGE>
 
       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 after due inquiry, there is
       not now, and there has never been, any employment by Sequoia

                                     I-22
<PAGE>
 
       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 repre
sentations 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

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 Schedules or Exhibits delivered by it under this Agreement,
promptly after the occurrence of the

                                     I-23
<PAGE>
 
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 condi
tion 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-24
<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 their

                                     I-25
<PAGE>
 
       business organizations and good will, keep available the services of
       their respective officers and employees and maintain good relationships
       with suppliers, 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 or (ii) split, combine or reclassify any of its outstanding
       securities or declare, set aside or pay any dividend or other
       distribution or make any exchange for or redemption of any such
       securities payable in cash, stock or property with respect to such
       securities;

              (c)  neither it nor any of its Subsidiaries shall (i) issue or
       agree to issue any additional shares of, or rights of any kind to acquire
       any shares of, its capital stock of any class or (ii) enter into any
       contract, agreement, commitment or arrangement with respect to any of the
       foregoing;

              (d)  neither it nor any of its Subsidiaries shall create, incur or
       assume any long-term or short-term indebtedness for money borrowed or
       make any capital expenditures or commitment for capital expenditures,
       except in the ordinary course of business and consistent with past
       practice;

              (e)  neither it nor any of its Subsidiaries shall (i) adopt, enter
       into or amend any bonus, profit sharing, compensation, stock option,
       warrant, pension, retirement, deferred compensation, employment,
       severance, termination or other employee benefit plan, agreement, trust
       fund or arrangement for the benefit or welfare of any officer, director
       or employee, except as provided in Section 7.02 hereof, or (ii) agree to
       any material (in relation to historical compensation) increase in the
       compensation payable or to become payable to, or any increase in the
       contractual term of employment of, any officer, director or employee
       except, with respect to employees who are not officers or directors, in
       the ordinary course of business in accordance with past practice;

              (f)  neither it nor any of its Subsidiaries shall sell, lease,
       mortgage, encumber, or otherwise dispose of or grant any interest in any
       of its assets or properties except for sales, encumbrances and other
       dispositions or grants in the ordinary course of business and consistent
       with past practice and except for liens for taxes not yet due or liens or
       encumbrances that are not material in amount or effect and do not impair

Sequoia or the Seller pertaining to this Agreement or the Merger shall be
reviewed and approved prior to release by SAC; provided, however, that such

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.

       7.10.  UPDATING OF EXHIBITS AND DISCLOSURE DOCUMENTS.  Sequoia shall
notify SAC of any changes, additions or events which may cause any material
change in or addition to the Sequoia Disclosure Document or any Schedules or
Exhibits delivered by it under this Agreement promptly after the occurrence of
the same and again at the Closing by delivery of appropriate updates to the
Sequoia Disclosure Document and to all such Schedules and Exhibits. No such
notification made pursuant to this Section shall be deemed to cure any breach of
any representation or warranty made in this Agreement unless SAC specifically
agrees thereto in writing nor shall any such notification be considered to
constitute or give rise to a waiver by SAC of any condition set forth in this
Agreement.

to in Section 6.06 above, the foregoing representations shall remain in effect
and Sequoia shall be responsible for all information regarding Sequoia contained

       10.01. TERMINATION.  This Agreement and the Merger may be terminated at
any time prior to the Closing, whether before or after any approval by
shareholders:

              (a)  By mutual consent of SAC and Sequoia; or

              (b)  By either SAC or Sequoia, upon written notice to the other,
       if the conditions to such party's obligations to consummate the Merger,
       in the case of SAC, as provided in Section 8.01, or, in the case of
       Sequoia, as provided in Section 8.02, cannot reasonably be satisfied on
       or before December 31, 1995 unless the failure of condition is the result
       of the material breach of this Agreement by the party seeking to
       terminate.

       10.02. AMENDMENT.  This Agreement may be amended by Sequoia and SAC by
action taken at any time but after the Merger has been approved by the Sequoia
Shareholders no amendment shall be made which materially reduces the
Consideration or which in any way materially and adversely affects the rights of
Sequoia or its shareholders without the further approval of such Sequoia
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
Seller appoints Sequoia the agent and attorney-in-fact of such Seller to the
extent (but only to the extent) necessary to bind the Seller to amendments to
this Agreement approved by Sequoia to the limited extent set forth in this
Section 10.02

       10.03. WAIVER.  At any time prior to the Closing Date, SAC or Sequoia, by
action taken by their respective Boards of Directors, may (a) extend the time
for the performance of any of the obligations or other acts of the other parties
hereto, (b) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto or (c) waive
compliance with any of the agreements or conditions contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
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.

       (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 is
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:

       (c)    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 Section 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; CONSENTS

       (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 of such approval, accompanied
by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
the price

                                      II-1
<PAGE>
 
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;
                    UNCERTIFIED 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
share 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 share, 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 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 thereof 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 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).

                                      II-3
<PAGE>
 
       (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.

       (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.

<PAGE>
 
       (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 attach 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 the 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 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 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

                                      II-1
<PAGE>
 
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 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
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first

                                      II-3
<PAGE>
 
class mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

       The undersigned registrant hereby undertakes to supply by means of a 
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

       The undersigned Registrant hereby undertakes as follows: prior to any
public offering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

       The Registrant undertakes that every prospectus (i) that is filed
pursuant to the immediately preceding paragraph or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used
in connection with the offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes 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 bona fide offering hereof.

                                  SIGNATURES


       Pursuant to the requirements of the Securities Act of 1933, the
registrant has duly caused this registration statement to be signed on its

                            EXCULPATORY PROVISIONS
                            ----------------------

  No director of the Corporation shall be liable to the Corporation or any of
its shareholders for monetary damages for breach of fiduciary duty as a
director, provided that this provision does not eliminate the liability of the
director (i) for any breach of the director's duty of loyalty to the Corporation
or its shareholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 1053 of the Oklahoma General Corporation Act, or (iv) for any
transaction from which the director derived an improper personal benefit. For
purposes of the prior sentence, the term "damages" shall, to the extent
permitted by law, include without limitation, any judgment, fine, amount paid in
settlement, penalty, punitive damages, excise or other tax assessed with respect
to an employee benefit plan, or expense of any nature (including, without
limitation, counsel fees and disbursements). Each person who serves as a
director of the Corporation while this Article X is in effect shall be deemed to
be doing so in reliance on the provisions of this Article X, and neither the
amendment or repeal of this Article X, nor the adoption of any provision of this
Certificate of Incorporation inconsistent with this Article X, shall apply to or
have any effect on the liability or alleged liability of any director or the
Corporation for, arising out of, based upon, or in connection with any acts or
omissions of such director occurring prior to such amendment, repeal, or
adoption of an inconsistent provision. The provisions of this Article X are
cumulative and shall be in addition to and independent of any and all other
limitations on or eliminations of the liabilities of directors of the
Corporation, as such, whether such limitations or eliminations arise under or
are created by any law, rule, regulation, bylaw, agreement, vote of shareholders
or disinterested directors, or otherwise.

  If the Oklahoma General Corporation Act is amended to further limit or
eliminate liability of this Corporation's directors for breach of fiduciary
duty, then a director of this Corporation shall not be liable for any such
breach to the fullest extent permitted by the Oklahoma General Corporation Act
as so amended. If the Oklahoma General Corporation Act is amended to increase or
expand liability of the Corporation's directors for breach of fiduciary duty, no
such amendment shall apply to or have any effect on the liability or alleged
liability of any director of this Corporation for or with respect to any acts or
omissions of such director occurring prior to the time of such amendment or
otherwise adversely affect any right or protection of a director of this
Corporation existing at the time of such amendment.
