                   PROXY STATEMENT/PROSPECTUS


This Proxy Statement of CAMAX Manufacturing Technologies, Inc., a Minnesota
corporation ("CAMAX"), and Prospectus of Structural Dynamics Research
Corporation, an Ohio corporation ("SDRC"), (the "Proxy
Statement/Prospectus") is being furnished to the shareholders of CAMAX in
connection with the solicitation of proxies by the Board of Directors of
CAMAX for use at a special meeting of shareholders to be held on
_________________, 1996 (the "Special Meeting").  This Proxy
Statement/Prospectus also constitutes a prospectus of SDRC in respect of up
to 2 million shares of the common stock of SDRC to be issued in connection
with the proposed Merger (as defined herein).

At the Special Meeting, holders of shares of CAMAX common stock, no par
value ("CAMAX Common Stock"), will be asked to adopt an Agreement of Merger
and Plan of Reorganization dated as of January 16, 1996 by and among CAMAX,
SDRC and SDRC Systems, Inc. ("Acquisition Corp.") (the "Merger Agreement"). 
Pursuant to the Merger Agreement, CAMAX will merge with and into Acquisition
Corp. (the "Merger"), and the Articles of Incorporation of Acquisition Corp.
will be amended to change the name of Acquisition Corp. to CAMAX
Manufacturing Technologies, Inc.  At the time the Merger becomes effective,
the CAMAX shareholders will receive, in the aggregate, shares of SDRC common
stock, no par value ("SDRC Common Stock"), having a total value of $30
million (the "Total Value") in exchange for all of the shares of CAMAX
Common Stock issued and outstanding on the effective date of the Merger (the
"Effective Date").  The total number of shares of SDRC Common Stock to be
issued in the Merger shall be determined by dividing the Total Value by the
Applicable Market Value Per Share of SDRC Common Stock.  The "Applicable
Market Value Per Share of SDRC Common Stock" will be the average of the per
share closing price of SDRC Common Stock as reported on the Nasdaq National
Market for the twenty trading days ending on the fifth trading day prior to
the Effective Date.

Ten percent of the total shares to be issued to the CAMAX shareholders in
the Merger will be placed in escrow at the Effective Date until the earlier
of the date SDRC files with the Commission its Report on Form 10-K for the
year ended December 31, 1996 or the first anniversary of the Effective Date,
which shares SDRC will have the right to redeem pursuant to the
indemnification obligations of CAMAX set forth in the Merger Agreement. 
Each CAMAX shareholder will receive that number of shares of SDRC Common
Stock to be issued in the Merger (less the number of shares to be retained
under the Merger Agreement) which represents each shareholder's pro rata
percentage of the CAMAX Common Stock owned immediately prior to the Merger. 
Only whole shares of SDRC Common Stock will be issued in connection with the
Merger.  No fractional shares will be issued.  Any shareholder otherwise
entitled to receive a fractional share will receive cash in lieu thereof
based upon the Applicable Market Value Per Share of SDRC Common Stock,
determined as provided above.

Under the rules and regulations of the Securities and Exchange Commission
(the "Commission"), the solicitation of CAMAX's shareholders to approve the
Merger constitutes an offering of SDRC Common Stock to be issued in
connection with the Merger.  Accordingly, SDRC has filed with the Commission
a Registration Statement on Form S-4 under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to such offering, and this
Proxy Statement/Prospectus does not contain all of the information set forth
in such Registration Statement, certain parts of which are omitted in
accordance with the rules and regulations of the Commission.

This Proxy Statement/Prospectus shall not constitute a prospectus for public
reoffering of the SDRC Common Stock issuable pursuant to the Merger.

THE SECURITIES OF SDRC TO BE ISSUED IN THE MERGER HAVE NOT BEEN APPROVED OR
DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
SECURITIES COMMISSION, NOR HAS THE COMMISSION OR ANY STATE SECURITIES
COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY
STATEMENT/PROSPECTUS, ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
OFFENSE.

The date of this Proxy Statement/Prospectus is _______________, 1996.

[THE BALANCE OF THIS PAGE HAS BEEN LEFT INTENTIONALLY BLANK]

Terms of the Merger and Reasons for the Merger; Conversion of CAMAX Common
Stock; Stock Consideration: Upon consummation of the Merger, the
shareholders of CAMAX will receive, in the aggregate, shares of SDRC Common
Stock having a total value of $30 million (the "Total Value"), in exchange
for all of the shares of CAMAX Common Stock issued and outstanding on the
Effective Date.  The total number of shares of SDRC Common Stock to be
issued in the Merger shall be determined by dividing the Total Value by the
Applicable Market Value Per Share of SDRC Common Stock.  The "Applicable
Market Value Per Share of SDRC Common Stock" will be the average of the per
share closing prices of SDRC Common Stock as reported on the Nasdaq National
Market for the twenty trading days ending on the fifth trading day prior to
the Effective Date.  Ten percent of the total shares to be issued to the
CAMAX shareholders in the Merger will be placed in escrow at the Effective
Date pursuant to the Merger Agreement until the earlier of the date SDRC
files with the Commission its Report on Form 10-K for the year ended
December 31, 1996 or the first anniversary of the Effective Date, which
shares SDRC will have the right to redeem pursuant to the indemnification
provisions of the Merger Agreement and Escrow Agreement (as defined below). 
Both companies determined that the merger of CAMAX with and into SDRC would
be beneficial to the companies and their shareholders.  Among the reasons
for consummating the Merger are that CAMAX shareholders will receive a
premium price for their stock in the Merger and SDRC, by acquiring a company
to broaden and enhance its computer-aided manufacturing business, will be
able to meet certain of its strategic corporate objectives.  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER - Conversion of Shares of CAMAX Common
Stock"; "- Exchange Ratio"; "- Retention of Shares and Redemption by SDRC";
"- Escrow Agreement", and "- Background and Reasons for the Merger."

No Fractional Shares:  No fractional shares will be issued in connection
with the Merger.  CAMAX shareholders will receive cash in lieu of any
fractional shares which they would otherwise be entitled to receive, based
on the Applicable Market Value Per Share of SDRC Common Stock as defined
above.  See "TERMS AND CONDITIONS OF THE PROPOSED MERGER - No Fractional
Shares."

Conditions of Closing:  The Merger is subject to several significant
conditions, including, but not limited to, CAMAX shareholder approval and
other regulatory approvals, including the filing of a pre-merger

Stock to be issued in the Merger, a tax opinion provided to the parties by
SDRC's counsel, identification of CAMAX employees to be employed by SDRC,
the SDRC Common Stock to be issued is approved for listing on the Nasdaq
National Market, no order of any court preventing consummation of the Merger
and the execution and delivery of an Escrow Agreement as of the Effective
Date.  

SDRC and CAMAX each filed an HSR Act pre-merger notification on February 8,
1996.  Under the HSR Act, the Merger may not be consummated until the
expiration of a waiting period of at least 30 days following the receipt of
each filing, unless the waiting period is earlier terminated by the
Antitrust Division or FTC (as defined herein).  On March __, 1996, notice
of early termination under the Act was received by the parties.  See "TERMS
AND CONDITIONS OF THE PROPOSED MERGER - Regulatory Approvals."

SDRC's obligation to consummate the Merger is conditioned, without
limitation, upon the following:  CAMAX's representations and warranties
being true and  correct as of the dates set forth in the Merger Agreement;
CAMAX having performed all of its covenants and obligations on or prior to
the Effective Date; delivery and review of CAMAX's audited financial
statements for the year ended December 31, 1995; assurances by letter from
SDRC's and CAMAX's accountants that the Merger may be accounted for as a
pooling of interests; holders of not more than 10% of the outstanding shares
of CAMAX Common Stock having exercised dissenters' rights; CAMAX's
liabilities on the December 31, 1995 audited balance sheet not exceeding by
20% the liabilities on CAMAX's audited balance sheet dated December 31,
1994; CAMAX's shareholders equity on the audited balance sheet dated
December 31, 1995 being not less than the shareholders' equity on the
audited balance sheet dated December 31, 1994; receipt of an opinion from

property counsel; receipt of consents necessary to permit SDRC to continue
CAMAX's business after the Effective Date; severance arrangements in place

true and correct as of the dates set forth in the Merger Agreement; SDRC
having performed all of its covenants and obligations on or prior to the
Effective Date; receipt of an opinion from SDRC's corporate counsel and the
provision by SDRC of certain closing documents.  See "TERMS AND CONDITIONS
OF THE PROPOSED MERGER - Conditions to Closing."

[THE BALANCE OF THIS PAGE HAS BEEN LEFT INTENTIONALLY BLANK]

Effective Date; Right to Terminate:  The Effective Date will, unless the
parties agree otherwise, occur as soon as practicable after all of the
conditions precedent to the closing required by the Merger Agreement,
including receipt of all regulatory approvals and the expiration of any
applicable waiting periods, have been fully met or effectively waived. 
CAMAX and SDRC each will have the right to terminate the Merger Agreement
if the other party does not satisfy, on or before the Effective Date, the
conditions set forth in the Merger Agreement, or if the Effective Date does
not occur on or before June 30, 1996.  The Merger Agreement automatically
terminates if the CAMAX shareholders do not approve the Merger and Merger
Agreement.  See "TERMS AND CONDITIONS OF THE PROPOSED MERGER - Effective
Date"; and " - Conditions to Closing."

Procedure for Exchange of Shares:  Promptly after the Effective Date, SDRC's
exchange agent will mail to each shareholder of CAMAX a form of transmittal
letter and instructions for the surrender of CAMAX Common Stock certificates
for certificates representing the shares of SDRC Common Stock to which such
shareholder is entitled.  Certificates for shares of SDRC Common Stock will
be issued to shareholders of CAMAX only after their certificates of CAMAX
Common Stock have been surrendered in accordance with such instructions. 
See "TERMS AND CONDITIONS OF THE PROPOSED MERGER - Exchange of
Certificates."

Federal Income Tax Consequences:  The Merger is conditioned, in part, upon
receipt of an opinion of SDRC's counsel with respect to certain tax matters,
including an opinion that no gain or loss (other than with respect to cash
received in lieu of fractional shares or cash received upon the exercise of
dissenters' rights) will be recognized by CAMAX's shareholders upon the
exchange of their CAMAX Common Stock for SDRC Common Stock.  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER - Federal Income Tax Consequences." 
Shareholders are urged to consult their own tax advisors as to the specific
consequences to them of the Merger under federal, state, local and any other
applicable tax laws.

Accounting:  It is intended that the Merger will be accounted for by the
pooling-of-interests method in accordance with generally accepted accounting
principles.  See "TERMS AND CONDITIONS OF THE PROPOSED MERGER - Accounting
Treatment."

will assume the obligations of CAMAX under the CAMAX Systems, Inc. 1985
Incentive Stock Option Plan, the Point Control Co. 1987 Incentive Stock
Option Plan, the CAMAX Systems, Inc. 1987 Non-Qualified Stock Option Plan,
the CAMAX Manufacturing Technologies, Inc. 1995 Long-Term Incentive and
Stock Option Plan and the CAMAX Manufacturing Technologies, Inc. 1995
Directors' Stock Option Plan  (individually, a "CAMAX Option Plan" and,
collectively, the "CAMAX Option Plans"), and each outstanding option to
purchase CAMAX Common Stock ("CAMAX Stock Options") granted under the CAMAX
Option Plans will become an option to acquire SDRC Common Stock on the same
terms and conditions as were applicable under the CAMAX Option Plans, except
that the number of shares subject to each option and the exercise price will
be appropriately adjusted to give effect to the ratio at which shares of
CAMAX Common Stock will be converted into shares of SDRC Common Stock as a
result of the Merger.  See "TERMS AND CONDITIONS OF THE PROPOSED MERGER -
Exchange Ratio."  At the Effective Date, SDRC will also assume the
obligations of CAMAX under three individual non-qualified stock options
granted by Point Control Co. to certain individuals prior to the 1994 merger
between Point Control Co. and CAMAX (the "CAMAX Non-Qualified Options"),
which represent the right to purchase 106,500 shares of CAMAX Common Stock. 
The CAMAX Non-Qualified Options will become options to acquire SDRC Common
Stock on the same terms and conditions as were applicable under the CAMAX
Non-Qualified Options, except that the number of shares subject to each
option and the exercise price will be appropriately adjusted to give effect
to the ratio at which shares of CAMAX Common Stock will be converted into
shares of SDRC Common Stock as a result of the Merger.  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER - Exchange Ratio" and "- Stock Options and
Stock Ownership Plan."

Interests of Certain Persons in the Merger:  Pursuant to the Merger
Agreement, SDRC will choose prior to the Effective Date those CAMAX
employees it determines it will retain after the Effective Date.  Each
employee of CAMAX who becomes an employee of SDRC or its subsidiaries
subsequent to the Merger will be entitled to participate in all employee
benefit plans sponsored by SDRC or its subsidiaries on the same terms and
to the same extent as similarly situated employees of SDRC.  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER - Effect on CAMAX Employees" and "-
Interests of Certain Persons in the Merger."

Recommendation of the Board of Directors of CAMAX: The Board of Directors
of CAMAX believes that the Merger is in the best interests of CAMAX and its
shareholders and has unanimously approved the Merger and the Merger
Agreement.  The Board of Directors of CAMAX unanimously recommends adoption
of the Merger and Merger Agreement to its shareholders.  This recommendation
is based on a number of factors discussed in this Proxy
Statement/Prospectus.  See "TERMS AND CONDITIONS OF THE PROPOSED MERGER -
Background and Reasons for the Merger."

Securities Involved:  For a comparative analysis of CAMAX Common Stock and
SDRC Common Stock, see "DESCRIPTION OF CAPITAL STOCK" and "COMPARISON OF
RIGHTS OF SHAREHOLDERS." 

Opinion of Wessels, Arnold & Henderson:  Wessels, Arnold & Henderson L.L.C.
("WA and H"), a financial advisor hired by CAMAX, has delivered its written
opinion dated January 16, 1996, to the Board of Directors of CAMAX that, as
of such date, the Total Value to be received by the shareholders of CAMAX
in the Merger is fair to the holders of CAMAX Common Stock from a financial
point of view.  WA&H has updated such opinion in an opinion dated the date
of this Proxy Statement/Prospectus.  A copy of the opinion of WA&H dated the
date of this Proxy Statement/Prospectus, which sets forth the assumptions
made, matters considered and limits on the review undertaken, is attached
as Annex B to this Proxy Statement/Prospectus and is incorporated herein by
reference.  Shareholders of CAMAX are urged to read the opinion in its

[THE BALANCE OF THIS PAGE HAS BEEN LEFT INTENTIONALLY BLANK]

Management of Acquisition Corp. after the Merger; Effects of the Merger: 
Acquisition Corp., as the surviving corporation in the Merger (the
"Surviving Corporation"), will remain a direct, wholly owned subsidiary of
SDRC upon consummation of the Merger and will be renamed "CAMAX
Manufacturing Technologies, Inc." at the Effective Date.  The directors of
Acquisition Corp.  immediately prior to the Effective Date will be the
initial directors of the Surviving Corporation, and the officers of
Acquisition Corp. immediately prior to the Effective Date will be the
initial officers of the Surviving Corporation.  SDRC has agreed in the
Merger Agreement to assume all CAMAX Stock Options granted under the CAMAX
Option Plans and the CAMAX Non-Qualified Options.  Certain members of the
management of CAMAX have certain interests in connection with the Merger
that are in addition to the interests of shareholders of CAMAX generally. 
See "TERMS AND CONDITIONS OF THE PROPOSED MERGER - Interests of Certain
Persons in the Merger;" and " - Stock Options and Stock Ownership Plan."

Dissenters' Rights of Appraisal:  Under Sections 302A.471 and 302A.473 of
the Minnesota Business Corporation Act, copies of which are attached hereto
as Annex C, shareholders of CAMAX, under certain circumstances and by
following prescribed statutory procedures, have the right to seek appraisal
for the "fair value" of such holders' shares.  The failure of a shareholder
choosing to execute such right to follow such procedures may result in
termination or waiver of dissenters' appraisal rights.  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER - Rights of Dissenting Shareholders" and
Annex C.  The obligations of SDRC and Acquisition Corp. to consummate the
Merger are subject to the condition that the holders of not more than 10%
of the CAMAX Common Stock entitled to vote at the Special Meeting shall have
asserted and not effectively withdrawn or lost the right to obtain the fair
value of such holders' shares pursuant to applicable provisions of the
Minnesota Business Corporation Act. See "TERMS AND CONDITIONS OF THE
PROPOSED MERGER - Conditions to Closing."

Resales of SDRC Common Stock:  The shares of SDRC Common Stock to be issued
to shareholders of CAMAX in connection with the Merger have been registered
under the Securities Act.  All shares of SDRC Common Stock received by
holders of CAMAX Common Stock upon consummation of the Merger will be freely
transferable by those shareholders of CAMAX not deemed to be "affiliates"
of CAMAX or SDRC.  Shares of SDRC Common Stock held by those CAMAX
shareholders who are deemed to be "affiliates" will be subject to
restrictions on transferability.  See "RESALE OF SDRC COMMON STOCK ISSUED
IN THE MERGER." 

MARKET PRICE FOR COMMON STOCK

SDRC Common Stock is traded on the Nasdaq National Market under the symbol
"SDRC."  There is no public market for the CAMAX Common Stock.  The
following table sets forth the closing price per share of SDRC Common Stock
and the "equivalent per share price" (as defined below) of the CAMAX Common
Stock as of (a) January 16, 1996, the last day of trading of SDRC Common
Stock before the announcement of the Merger, and (b) _________________,
1996, the latest practicable trading day before the filing of this Proxy
Statement/Prospectus with the Commission.  The "equivalent per share price"
of CAMAX Common Stock as of such dates equals the closing price per share
of SDRC Common Stock on such dates multiplied by .0636, which is the assumed
number of shares of SDRC Common Stock into which each share of CAMAX Common
Stock is to  be converted based upon the number of shares of CAMAX Common
Stock issued and outstanding as of the date of this Proxy
Statement/Prospectus as though January 16, 1996 was the Effective Date and
the price was calculated as set forth in the Merger Agreement.  There can
be no assurance that the prices indicated for the SDRC Common Stock will be
indicative of the future market prices of SDRC Common Stock following
consummation of the Merger.

Market Price            SDRC               Equivalent Per Share Price
Per Share At            Common Stock       of CAMAX Common Stock

[THE BALANCE OF THIS PAGE HAS BEEN LEFT INTENTIONALLY BLANK]<PAGE>
    SELECTED HISTORICAL AND PROFORMA CONSOLIDATED FINANCIAL DATA

The following tables set forth selected historical consolidated financial
data of SDRC and CAMAX and unaudited combined proforma financial data giving
effect to the Merger using the pooling-of-interests method of accounting and
reflecting the Exchange Ratio and the proforma adjustments described in the
accompanying notes.

The selected consolidated financial information as of December 31, 1993 and
1994 and for the three years then ended 1994 for SDRC and CAMAX has been
derived from the consolidated financial statements of SDRC and CAMAX, which
statements have been audited by Price Waterhouse LLP and Deloitte & Touche
LLP, respectively, independent accountants.  The selected consolidated
financial information as of December 31, 1990, 1991 and 1992 and for the two
years ended December 31, 1991 for SDRC and CAMAX has been derived from the
consolidated financial statements of SDRC and CAMAX as of and for those
periods.  The selected historical consolidated financial data for SDRC and
CAMAX for the nine-month periods ended September 30, 1995 and 1994 have been
derived from SDRC's and CAMAX's consolidated unaudited financial statements
and include, in the opinion of SDRC's and CAMAX's management, all
adjustments necessary to present fairly the data for such periods.

The historical consolidated financial information and selected financial
data for CAMAX reflect the merger between CAMAX and Point Control Co. (the
"Point Control Co. Merger") which was accounted for as a pooling-of-interests. 
The Point Control Co. Merger was effected in September 1994
through the exchange of 17.75 shares of CAMAX Common Stock for each share
(approximately 395,000 shares) of Point Control Co. common stock held. 

The proforma information set forth below is for illustrative purposes only
and is not necessarily indicative of the operating results or financial
position that would have occurred if the Merger had been consummated as of
the dates specified, nor is it necessarily indicative of future operating
results or financial position.  No provision has been reflected in the
unaudited proforma combined condensed operating data for direct expenses
related to the Merger, which are expected to approximate $____ million.  The
unaudited proforma combined condensed financial information also excludes
any benefits from synergies that may result from the Merger.  The unaudited
proforma combined selected financial information should be read in
conjunction with "Proforma Combined Financial Information."  See "PROFORMA
FINANCIAL STATEMENTS."

Comparative net income (loss) and book value per share data of SDRC and
CAMAX are also set forth below on both a historical and a proforma combined
basis and on a per share equivalent proforma basis.  CAMAX data reflects the
Point Control Co. Merger accounted for as a pooling-of-interests.  Proforma
combined net income (loss) per share is derived from the proforma combined
information presented elsewhere herein, which gives effect to the Merger
under the pooling-of-interests accounting method as if the Merger had
occurred at the beginning of each period and combines the results of SDRC
and CAMAX for the periods presented.  The per share equivalent proforma
combined data is based upon the estimated ratio of shares of CAMAX Common
Stock exchanged for shares of SDRC Common Stock pursuant to the Merger
Agreement.  Book value per share for the proforma combined presentation is
based upon the number of outstanding shares of SDRC Common Stock, adjusted
to include the estimated number of shares of SDRC Common Stock to be issued
as a result of the Merger.  The adjusted share amounts are based on
historical share amounts after giving effect to the proforma adjustments
described elsewhere herein and converting each share of CAMAX Common Stock
into .0636 shares of SDRC Common Stock.  As stated in the Merger Agreement,
the Exchange Ratio is based upon the market value of SDRC's Common Stock for
the twenty day trading period ending five days prior to the Effective Date.

COMPARATIVE PER SHARE DATA
<TABLE>
The following table sets forth certain historical per share data of CAMAX
and SDRC and CAMAX equivalent and proforma combined per share data based on
the assumption that the Merger was effective January 1, 1992 and that the
Merger was accounted for by the pooling-of-interests accounting method.  The
proforma combined per share data is derived from the financial information
in the Proforma  Financial Statements.  The number of shares used for
calculating CAMAX equivalent per share amounts is based on the exchange
ratio of .0636 for CAMAX Common Stock which is based on the assumption of
18,211,692 shares of CAMAX Common Stock issued and outstanding as of
December 31, 1995.  The proforma data is not necessarily indicative of
amounts which would have been achieved had the Merger been consummated at
the beginning of the periods presented and should not be construed as
representative of future operations.  This data should be read in
conjunction with the Proforma Combined Financial Statements and notes
thereto included elsewhere herein, and the separate historical consolidated
financial statements and notes thereto of CAMAX and SDRC, included elsewhere
and incorporated by reference herein, respectively.

OF THE PROPOSED MERGER" below.

the Special Meeting.  As of the Record Date, there were approximately _____
shareholders of record of CAMAX Common Stock.  As of the Record Date there

Voting and Revocability of Proxies

All properly executed proxies that are not revoked will be voted at the
Special Meeting and any postponement or adjournment thereof, in accordance
with the instructions contained therein.  Proxies containing no instructions
regarding the proposals specified in the form of proxy will be voted for
approval of the Merger and the Merger Agreement at the Special Meeting. 
Each record holder of CAMAX Common Stock on the Record Date is entitled to
cast one vote per share, exercisable in person or by properly executed
proxy, on each matter properly submitted for a vote of the shareholders at
the Special Meeting.

If an executed proxy card is returned and a shareholder has abstained from
voting on any matter, the shares represented by such proxy will be
considered present at the Special Meeting for purposes of determining a
quorum and for purposes of calculating the vote, but will not be considered
to have been voted in favor as to such matter.

The presence of a shareholder at the Special Meeting for which such
shareholder has executed a proxy will not automatically revoke such
shareholder's proxy.  A shareholder may, however, revoke a proxy at any time
prior to its exercise by filing a written notice of revocation with, or by
delivering a duly executed proxy bearing a later date to, the Secretary of
CAMAX at the address of the principal executive offices of CAMAX, or by
attending the Special Meeting and voting in person.

Shareholder Votes Required

The presence, in person or by proxy, of a majority of the shares of CAMAX
Common Stock outstanding on the Record Date is necessary to constitute a
quorum at the Special Meeting.  Approval of the Merger and the Merger
Agreement requires the affirmative vote of holders of a majority of the
shares of CAMAX Common Stock outstanding on the Record Date.

It is expected that all of the shares of CAMAX Common Stock beneficially
owned by directors and executive officers of CAMAX and their affiliates on
the Record Date, excluding shares subject to stock options, will be voted
for approval of the Merger and the Merger Agreement.

Solicitation of Proxies; Expenses

CAMAX will bear the costs of soliciting proxies from its shareholders, and
will bear all printing and mailing costs in connection with the preparation
and mailing of this Proxy Statement/Prospectus to CAMAX shareholders.  In
addition to solicitation by mail, the directors, officers and employees of
CAMAX may solicit proxies from shareholders by telephone, facsimile or
letter or in person, but will not be specially compensated for such
activities.

                 TERMS AND CONDITIONS OF THE PROPOSED MERGER

The following description contains, among other information, a summary of
certain provisions of the Merger Agreement and is qualified in its entirety
by reference to the full text thereof, a copy of which is appended as Annex
A to this Proxy Statement/Prospectus and is incorporated herein by
reference.

Background and Reasons for the Merger

CAMAX Background of the Merger.  Early in 1995, management of CAMAX embarked
on an aggressive strategic planning effort to ensure that CAMAX would be in
a position to assert its CAM leadership in the computer-aided design
("CAD")/CAM industry and bring change and improvement to such industry. 
Early in the strategic planning effort, management of CAMAX decided that it
needed a partner to obtain its goal of being the CAM leader in the industry. 
Management of CAMAX believed that the solutions for success in the
mechanical engineering marketplace would be to possess excellence in certain
key areas: CAD, CAM, computer-aided engineering ("CAE") and Product
Information Management ("PIM") and to take that know-how and develop tools
and services that can improve a customer's ability to make higher quality
products more quickly.  CAMAX believes it possesses unquestioned excellence
in the CAM industry, however, CAMAX also believes that it needs to combine
its expertise with other technical areas of the mechanical engineering
marketplace to best serve its customers.

On July 26, 1995, management of CAMAX and Wayne McClelland, Vice
President-Product Management-I-DEAS, of SDRC, met in Minneapolis, Minnesota
and reviewed the architecture of CAMAX's products and discussed CAMAX's
business operations in general.  On August 3, and August 4, 1995, Robert J.
Majteles, the Chief Executive Officer of CAMAX, Al Peter, the Chief
Executive Officer of SDRC, and Mr. McClelland met at SDRC's headquarters in
Milford, Ohio and discussed SDRC's products and business as well as SDRC's
product architecture.  On August 10, 1995, Messrs. Peter and McClelland
traveled to Minneapolis, Minnesota and met with Mr. Majteles to discuss
CAMAX's products and business in greater detail.  Messrs. Majteles and
McClelland had a telephone conference on August 22, 1995 during which they
discussed a potential purchase by CAMAX of all of SDRC's CAM assets and
possible joint ventures.  On August 24, 1995, Mr. McClelland met with Mr.
Majteles and Tom Greene, CAMAX's Vice President-Engineering, in Minneapolis,
Minnesota to further discuss potential asset acquisitions and joint
ventures.  On September 19, 1995, Messrs. McClelland, Majteles and Greene
had a telephone conference during which it was decided to terminate
negotiations regarding (i) CAMAX's purchase of SDRC's assets, and (ii) a
possible joint venture between CAMAX and SDRC.  On October 9 and October 10,
1995 at SDRC's headquarters in Milford, Ohio, Messrs. Peter, McClelland and
Majteles discussed a proposal for SDRC to acquire CAMAX.  On October 20,
1995, the CAMAX executive team met in Minneapolis, Minnesota to discuss a
potential acquisition of CAMAX by SDRC.  On October 23, 1995, SDRC made an
offer to acquire all of the capital stock of CAMAX in exchange for  $20
million of SDRC Common Stock.  At its regularly scheduled meeting on October
27, 1995, the Board of Directors of CAMAX considered SDRC's offer to acquire
CAMAX.  At the October 27 board meeting, management of CAMAX summarized its
opinions regarding the SDRC offer and discussed with the Board of Directors
the relevant terms of the SDRC offer.  The Board of Directors of CAMAX
rejected SDRC's $20 million offer for CAMAX and directed management of CAMAX
to convey such rejection to management of SDRC.

On October 21, 1995, Mr. Majteles requested that Mike Ogborne of WA&H
contact a certain corporation concerning CAMAX's interest in discussing the
possibility of an acquisition, joint venture or other form of transaction
to further CAMAX's strategic plan.  On November 4, 1995, Messrs. Majteles
and Ogborne met in Minneapolis, Minnesota to discuss the results of Mr.
Ogborne's contact and to prepare for a trip by Mr. Majteles to explore
possible transactions with such corporation.  On November 8 and November 9,
1995, Messrs. Majteles and Ogborne met with certain executive officers of
such corporation to discuss a potential acquisition of CAMAX.  On November
13, 1995, a group of such corporation's employees gathered at CAMAX's
headquarters in Minneapolis, Minnesota to conduct due diligence on CAMAX and
to discuss further a potential acquisition.

The Board of Directors of CAMAX met at CAMAX's headquarters in Minneapolis,
Minnesota on November 22, 1995 at which time it was decided to terminate all
contact with the corporation and to pursue a transaction with SDRC if SDRC
was willing to offer $30 million for the acquisition of all of the
outstanding capital stock of CAMAX.  On December 1, 1995, Messrs. Majteles
and Peter had a telephone conference during which time they discussed the
structure of a transaction whereby SDRC would acquire CAMAX.  Between
December 1, 1995 and December 7, 1995, members of management of both SDRC
and CAMAX, with the assistance of outside counsel, reviewed numerous drafts
of letters of intent and negotiated the terms of such letter of intent.  On
December 7, 1995, SDRC and CAMAX entered into a letter of intent (the
"Letter of Intent") whereby SDRC agreed to acquire all of the capital stock
of CAMAX in exchange for $30 million of SDRC Common Stock.  The Letter of
Intent prohibited CAMAX from initiating or holding discussions or
entertaining offers from any other parties concerning the acquisition or
change in control of CAMAX, however structured. 

CAMAX's Reasons for the Merger; Approval by CAMAX Board of Directors.  At
a special meeting of the Board of Directors of CAMAX held on Saturday,
January 13, 1996, at which all directors were present, the Board of
Directors of CAMAX unanimously determined that the Merger is fair to and in
the best interests of CAMAX and its shareholders, unanimously approved the
Merger Agreement and the transactions contemplated by the Merger Agreement
(subject to the resolution of open issues by CAMAX's management and to the
completion of satisfactory documentation) and unanimously resolved to
recommend that the shareholders of CAMAX vote for adoption of the Merger and
the Merger Agreement.  The Board of Directors of CAMAX held another special
meeting on Tuesday, January 16, 1996, at which all directors were present
except for Messrs. Blakely, Carlson and Lipkin, at which time the Board of
Directors were informed of the resolution of the open issues surrounding the
Merger and reaffirmed its approval of the Merger and the Merger Agreement
and its recommendation to the shareholders of CAMAX.  At the meetings held
on January 13 and January 16, 1996, CAMAX's Board of Directors received
advice or presentations from, and reviewed the then-current terms of the
Merger Agreement with, CAMAX's management and accounting, financial and
legal advisors.  The presentation by WA&H at the meeting held on January 13,
1996 is described below under "- Opinion of Wessels, Arnold and Henderson." 
The presentations by Dorsey and Whitney P.L.L.P. and Deloitte and Touche
LLP, CAMAX's legal and accounting advisors, respectively, described and
explained (i) the terms and conditions of the proposed Merger as set forth
in the drafts of the Merger Agreement, (ii) the fiduciary duties applicable
to CAMAX's Board of Directors in the evaluation of the proposed transaction,
(iii) the results of Dorsey and Whitney P.L.L.P.'s legal due diligence, and
(iv) the results of Deloitte and Touche LLP's accounting due diligence.

In reaching its conclusion to enter into the Merger Agreement and recommend
adoption of the Merger Agreement by CAMAX's shareholders, CAMAX's Board of
Directors considered a number of factors, including, without limitation, the
following:

   - The consideration to be received by CAMAX's shareholders in the Merger,
including the fact that the Applicable Value Per Share of SDRC Common Stock
represented a substantial premium over the then-current fair market value
of CAMAX Common Stock, and the relationship between the market value of SDRC
Common Stock and CAMAX's earnings and certain other measures.

   - The presentation by WA&H to CAMAX's Board of Directors at its meeting
on January 13, 1996, including WA&H's opinion dated January 16, 1996 to the
effect that, as of such date, the consideration to be received by the CAMAX
shareholders was fair from a financial point of view.  WA&H has updated such
opinion in a written opinion dated as of the date of this Proxy
Statement/Prospectus.  See "- Opinion of Wessels, Arnold & Henderson."

   - CAMAX's and SDRC's respective businesses, assets, management, financial
condition, results of operations and prospects.

    - The earnings per share of CAMAX Common Stock and SDRC Common Stock.

    -  The opportunity for holders of CAMAX Common Stock to continue to
share in the potential for long-term gains from their investment in CAMAX
through the ownership of SDRC Common Stock following the Merger.

    -  The terms and conditions of the Merger and the Merger Agreement,
including the amount and the form of the consideration, as well as the
parties' representations, warranties and covenants, and the conditions to
their respective obligations.

  - The expectation that the Merger will afford CAMAX's shareholders the
opportunity to receive SDRC Common Stock in a non-taxable transaction for
federal income tax purposes.

   - The expectation that the Merger will be accounted for as a pooling of
interests.

    - The products currently being developed by CAMAX are, to a large
extent, complementary with those offered by SDRC. The markets into which
CAMAX and SDRC products could be sold are similar.

    -  The CAMAX Common Stock is unregistered and no public market exists
for the CAMAX Common Stock.  Following the Merger, CAMAX's shareholders will
hold SDRC Common Stock which may be sold on an established market.

In view of the wide variety of factors considered in connection with its
evaluation of the terms of the Merger, CAMAX's Board of Directors did not
find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the specific factors considered in reaching its
determinations.  Based on the factors described above, CAMAX's Board of
Directors unanimously determined that the Merger is fair and in the best
interests of CAMAX and its shareholders, unanimously approved the Merger
Agreement and the transactions contemplated by the Merger Agreement and
unanimously resolved to recommend that the shareholders of CAMAX vote for
adoption of the Merger Agreement.

The Board of Directors of CAMAX has unanimously approved the Merger and the
Merger Agreement and recommends a vote for the adoption of the Merger and
the Merger Agreement.

SDRC Background and Reasons for the Merger.   Consistent with its strategic
objective of becoming the leading world-wide supplier of team engineering
solutions that encompass CAD, CAM, CAE and PIM, early in 1995 SDRC initiated
an in-depth evaluation of the CAM segment of the mechanical design
automation industry for the purpose of assessing not only where the CAM
industry was at that time but where it was heading in the future.  From this
in-depth strategic analysis, SDRC determined that a cornerstone of its long
term strategy and differentiation in the marketplace would be to offer
concurrent engineering solutions with balanced strength in CAD, CAM, CAE and
PIM. At the time, SDRC marketed (and still markets) a CAM product called
Generative Machining, an advanced technology product that has a number of
areas of uniqueness and strength.  Generative Machining is the only CAD/CAM
product with generative machining capability, it is based on current
architecture, the user interface is highly regarded and it is integrated
with SDRC's main product line, I-DEAS Master Series.  SDRC's Generative
Machining product, while considered in the industry as a quality product,
had acknowledged opportunities for enhancement, particularly in the area of
3- and 5-axis milling capabilities.

During the course of this evaluation, SDRC made the following observations
about trends in the CAM industry:

- -  The CAM market is viable, demonstrating double-digit growth in recent
years.  SDRC attributed this to the acceptance of concurrent engineering,
which positions manufacturing operations as of equal import to design;

- -  SDRC's main competitors have competitive CAM products;

- -  In SDRC's experience, most medium to large companies want an integrated
solution.  Companies buy numerical control (NC) software either as a
component in an integrated CAD/CAM solution or as a best of class product. 
As a general rule, most mid- to large-size companies prefer an integrated
solution and most small companies prefer a best of class solution;

- -  A strong CAM offering could have a positive spill-over effect on the CAD
and (PIM) segments of SDRC's business. Since many companies want an
integrated solution, there would be an opportunity to gain CAD and PIM
business on the strength of a more comprehensive CAM offering; and

- -  Quality CAM software is very difficult to produce and support. 
Programming today's NC machines is a difficult task and tomorrow's machines
will be even more complex. CAM software is going to require an increasing
degree of specialization, particularly as manufacturers want to improve
productivity.

Recognizing the opportunities to further strengthen and expand its CAM
offering, SDRC began to look at ways to move to improve its position in the
CAM industry.  As the evaluation proceeded, it became clear that there were
three main ways for SDRC to accomplish its goal.  First, SDRC could maintain
the status quo, hoping to leverage its strength in the CAD business while
offsetting its product enhancement requirements.  SDRC recognized that this
approach might hinder its ability to provide integrated CAE/CAD/CAM
solutions to its customers and place significant revenue at risk in the
short and long term.  Second, SDRC could further refine its Generative
Machining product internally to bring functionality to the level of other
leaders in the CAM industry.  This alternative presented a timing obstacle
in that SDRC would first have to recruit qualified developers.  Then, the
development effort would take a significant investment of time, creating
some risk that SDRC would fall behind in a rapidly moving market and be
unable to meet current customer demands.  The final alternative was to grow
in the CAM industry through acquisition.  While there could be short term 
issues to be resolved in acquiring and integrating another business with
SDRC's, growth through acquisition would provide SDRC with instant
resources, an immediate revenue stream and market impact.

Given SDRC's assessment that growth through acquisition would provide swift
and effective augmentation of its own CAM offering, SDRC then embarked on
a review and evaluation of the various competitors in the CAM market.  The
CAM marketplace is very fragmented.  There are more than 100 companies
providing CAM products to end users.  Given its interest in rapidly
improving  its position in the CAM segment, SDRC was primarily interested
in the market leaders.  SDRC spent months assessing the respective strengths
and weaknesses of the leaders in the CAM industry.  It evaluated product
offerings, revenues, customer base, market focus and product development
personnel.  Most importantly, SDRC evaluated how it could most effectively
capitalize  on potential synergies between a target company and SDRC.

It became clear to SDRC that the company that most met its profile of an
ideal CAM offering was CAMAX.  First, CAMAX's products, Camand and SmartCAM,
provide a broad NC software capability.  Camand offers strong surface
modeling and multi-axis milling capabilities.  SmartCAM, which CAMAX
acquired when it merged with Point Control Co. in 1994, has strong
production and 2 and 2 1/2 axis milling capabilities.  As compared to other
NC vendors, CAMAX provides a wide range of product capability.  If these
products were combined with SDRC's own Generative Machining, essentially all
of the important functions of NC would be covered.  Additionally, CAMAX
products would present little difficulty in transition and integration into
the standard SDRC product offering.

Secondly, in terms of revenue, CAMAX is the leading independent NC software
vendor.  CAMAX has a strong market presence and a large installed base of
customers.  For SDRC, market presence and customer loyalty were of utmost
importance.  CAMAX has a very positive image in the CAM market.  According
to  an independent industry analyst,  SmartCAM ranks number two and CAMAND
ranks number eight among all similar products.  CAMAX is well known and
respected in the CAM industry.  As regards customer loyalty, it was
essential for SDRC that the company it acquired provided immediate and 
long-term customer relationships.  With its 12,000 customer sites and 22,000
installed users worldwide, CAMAX best fit this element of SDRC's profile.

Thirdly, CAMAX has talented personnel with particular emphasis on its
product development staff.  A talented development staff  would be necessary
to meet the ongoing demands of SDRC's CAM customers.  CAMAX's and SDRC's
development staffs could integrate their shared knowledge of each other's
products strengths and weaknesses to produce a complete CAM offering.

In July and August of 1995, senior management of SDRC met with management
of CAMAX to discuss CAMAX's business and product architecture, and how they
might be integrated with SDRC's.  Management representatives of both
companies had a number of face-to-face and telephonic meetings during this
time period.  The main focus of the discussions was the mechanism for
combining the strengths of both parties' CAM products.  SDRC and CAMAX
considered many alternatives, including a joint venture and an asset
acquisition.  As the discussions progressed and continued into September,
it became apparent to SDRC that the best way for it to meet its strategic
objective of enhancing the CAM piece of its integrated offering would be to
acquire ownership of CAMAX.  An acquisition of the assets alone would give
SDRC only the software, but not the development staff to work with it, and
the relative risks of a joint venture made that alternative unattractive.

Throughout this period, SDRC engaged in an intensive internal valuation of
CAMAX.  The analysis included a number of factors, including historical
revenue, margins, product functionality and capability, strength and size
of customer base, sales volume, strength and size of reseller channels,
comparable transactions in the industry and strategic fit.

On October 23, 1995, SDRC made a written offer to acquire all of the capital
stock of CAMAX in exchange for $20 million of SDRC Common Stock.  The
written offer contained the customary contingencies and qualifications of
such an offer.  SDRC received written notice from CAMAX on or about October
27, 1995 that its Board of Directors had reviewed the offer and determined
that it was insufficient, thereby rejecting the offer.

SDRC continued to assess the importance of the acquisition of CAMAX to its
strategic objectives.  In light of the internal valuation it had performed
for CAMAX, SDRC management reopened discussions with CAMAX management in
late November and early December 1995 about the possibility of an
acquisition of CAMAX by SDRC.  The discussions at this point focused mainly
on price.  Management of both companies agreed in principle on a purchase
price of $30 million.  Between December 1, 1995 and December 7, 1995,
members of management of both SDRC and CAMAX, with the assistance of outside
counsel, reviewed numerous drafts of letters of intent and negotiated the
terms of such letter of intent.  On December 7, 1995, SDRC made a written
offer to acquire all of the capital stock of CAMAX in exchange for $30
million of SDRC Common Stock.  The written offer contained the customary
contingencies and qualifications of such an offer.  CAMAX accepted the
written offer of $30 million and signed the Letter of Intent, which was
contingent upon negotiation of a definitive merger agreement.

During the first week in January 1996, representatives of CAMAX and SDRC
commenced negotiations of the Merger Agreement.  The Chief Financial Officer
of CAMAX and CAMAX's outside legal counsel met in Cincinnati, Ohio on
January 14, 15 and 16, 1996 with representatives from SDRC and its outside
legal counsel to complete the negotiation of the Merger Agreement. 
Following approval by the respective boards of directors of SDRC and CAMAX,
the parties signed the Merger Agreement on January 16, 1996.

Effective Date

The Effective Date of the Merger will occur as soon as practicable after all
conditions precedent contained in the Merger Agreement have been met or
waived, including the expiration of all applicable waiting periods.  CAMAX
and SDRC each will have the right, but not the obligation, to terminate the
Merger Agreement if the Effective Date does not occur on or before June 30,
1996.

Conversion of Shares of CAMAX Common Stock

Each share of CAMAX Common Stock which is issued and outstanding immediately
prior to the Effective Date will be converted at the Effective Date into
SDRC Common Stock and cash in lieu of any fractional shares of SDRC Common
Stock.  See "Exchange Ratio" below.

The Exchange Ratio will be adjusted so as to give CAMAX shareholders the
economic benefit of any stock dividends, reclassifications,
recapitalizations, split-ups, exchanges of shares, distributions or
combinations or subdivisions of SDRC Common Stock or CAMAX Common Stock
effected between the date of the Merger Agreement and the Effective Date.

Exchange Ratio

At the Effective Date of the Merger, all of the shares of CAMAX Common Stock
that are issued and outstanding immediately prior to the Effective Date will
be converted by virtue of the Merger and without further action into that
number of shares of SDRC Common Stock determined by dividing $30 million
(the "Total Value") by the Applicable Market Value Per Share of SDRC Common
Stock (the "Exchange Ratio").  The "Applicable Market Value Per Share of
SDRC Common Stock" will be the average of the per share closing prices of
SDRC Common Stock as reported on the Nasdaq National Market for the twenty
trading days ending on the fifth trading day prior to the Effective Date. 
Each CAMAX shareholder will receive that number of shares of SDRC Common
Stock to be issued in the Merger (less that number of shares to be retained
by SDRC under the Merger Agreement and Escrow Agreement) which represents
each shareholder's pro rata percentage of the CAMAX Common Stock owned
immediately prior to the Merger.


Certificates representing shares of SDRC Common Stock will be distributed
to CAMAX shareholders upon the surrender of their certificates for shares
of CAMAX Common Stock to SDRC.  See "Exchange of Certificates" herein.

Indemnification

CAMAX has agreed that, from and after the Effective Date until the end of
the Retention Period (as defined below), CAMAX will indemnify and hold
harmless SDRC and/or the Surviving Corporation against any expense, loss,
damage, deficiency and/or cost, in the aggregate cumulative amount in excess
of $175,000 during the Retention Period, resulting from any
misrepresentation or breach by CAMAX of any representation, warranty or
covenant made by CAMAX in the Merger Agreement (except that any liability
or potential liability which accrues to CAMAX as a result of its compliance
with any of the covenants or conditions to closing specified in the Merger
Agreement shall not constitute a breach of any of CAMAX's representations
and warranties under the Merger Agreement).  Claims for indemnification made
by SDRC and/or the Surviving Corporation are to be made in accordance with
the Escrow Agreement and the shares of SDRC Common Stock held in escrow
under the terms of the Escrow Agreement are to be the sole remedy of SDRC
and/or the Surviving Corporation for indemnification under the Merger
Agreement.  See "-Escrow Agreement," and "- Retention of Shares and
Redemption by SDRC."

Retention of Shares and Redemption by SDRC

From and after the Effective Date until the earlier of the date SDRC files
with the Commission its Report on Form 10-K for the year ended December 31,
1996 or the first anniversary of the Effective Date (the "Retention
Period"), SDRC Common Stock which represents 10% of the total shares to be
issued to the CAMAX shareholders upon consummation of the Merger will be
placed into escrow pursuant to the terms of the Merger Agreement and the
Escrow Agreement.  SDRC will have the right to redeem such retained shares
as payment for any amounts due SDRC or Surviving Corporation pursuant to the
indemnification obligations of CAMAX set forth in the Merger Agreement.  For
the purposes of a redemption by SDRC, the redeemed shares will be valued at
a price per share equal to the Applicable Market Value Per Share of SDRC
Common Stock as of the Effective Date.

The process for redeeming retained shares will be substantially as described
in the Escrow Agreement appended as Annex D hereof (the "Escrow Agreement).

Upon the earlier of the date SDRC files with the Commission its Report on
Form 10-K for the year ended December 31, 1996 or the first anniversary of
the Effective Date, any retained shares not subject to redemption by SDRC
will be distributed to the CAMAX shareholders on a pro rata basis based upon
their percentage ownership of CAMAX Common Stock immediately prior to the
Effective Date in the same manner as for the Exchange Ratio.

Escrow Agreement

The Merger Agreement provides that 10% of the total shares of SDRC Common
Stock to be issued in the Merger to CAMAX shareholders will be placed into
escrow at the Effective Date pursuant to an Escrow Agreement by and among
CAMAX, SDRC, Terrence W. Glarner and Raymond A. Lipkin (the
"Representatives"), and First Trust National Association, a national banking
association (the "Escrow Agent") (the "Escrow Agreement").  The shares of
SDRC Common Stock to be retained in the Merger (the "Retention Shares") will
establish the escrow fund (the "Escrow Fund") and the Escrow Fund will fund
and be the sole source of securing the indemnification rights set forth in
the Merger Agreement.

Once the shares of SDRC Common Stock are in the Escrow Fund, CAMAX
shareholders will retain all voting rights with respect to such shares in
accordance with their proportionate interests in the shares and any cash
dividends paid on the Retention Shares will be distributed currently to the
CAMAX shareholders.  The Escrow Agreement also provides for the appointment
of Messrs. Glarner and Lipkin as Representatives to act by and on behalf of
the CAMAX shareholders following the Merger.  The Representatives will be
authorized to respond to the assertion of any and all claims for
indemnification by SDRC pursuant to the terms of the Escrow Agreement.

The shares retained in the Escrow Fund will be disbursed to satisfy a claim
for indemnification when either of the following is delivered to the Escrow
Agent:  (a) a certificate signed by SDRC and the Representatives certifying,
or (b) a certified copy of a final non-appealable judgment of a court of
competent jurisdiction determining, that an amount is due to SDRC pursuant
to the Merger Agreement and further specifying the number of shares of SDRC
Common Stock to be transferred thereunder.  The value of the stock to be
disbursed will be based upon the Applicable Market Value Per Share of SDRC
Common Stock as utilized in the Merger Agreement. Upon receipt of the
foregoing, the Escrow Agent is required to promptly cause certificates
representing the appropriate number of shares, with duly executed stock
powers and signatures guaranteed, to be delivered to SDRC.  No fractional
shares will be disbursed.

Upon the expiration of the Retention Period, SDRC will authorize the Escrow
Agent to deliver to the Representatives, on behalf of the CAMAX
shareholders, any shares remaining in the Escrow Fund, subject only to
shares which will continue to be retained pursuant to the Escrow Agreement
for claims which are in process at the time of the expiration of the
Retention Period.

Stock Options and Stock Ownership Plans

As of December 31, 1995, there were outstanding options to purchase
3,290,238 shares of CAMAX Common Stock held by certain directors, officers
and employees of CAMAX pursuant to the CAMAX Option Plans and the CAMAX Non-
Qualified Options.

Pursuant to the Merger Agreement, the CAMAX Option Plans and the CAMAX Non-
Qualified Options shall be assumed by SDRC and participants of such CAMAX
Option Plans and owners of CAMAX Non-Qualified Options shall be entitled to
receive, upon the exercise of options outstanding under the CAMAX Option
Plans and the CAMAX Non-Qualified Options, SDRC Common Stock on the same
terms and conditions as were applicable under the CAMAX Option Plans and the
CAMAX Non-Qualified Options on a pro-rata basis consistent with the Exchange
Ratio.

No Fractional Shares

Only whole shares of SDRC Common Stock will be issued in connection with the
Merger.  In lieu of fractional shares, each shareholder of CAMAX Common
Stock otherwise entitled to a fractional share of SDRC Common Stock will be
paid in cash an amount equal to the amount of such fraction multiplied by
the Applicable Market Value Per Share of SDRC Common Stock.  No such
shareholder will be entitled to dividends, voting rights or other rights in
respect of any such fractional share.

Exchange of Certificates

After the Effective Date, holders of certificates previously representing
shares of CAMAX Common Stock will cease to have any rights as shareholders
of CAMAX and their sole rights will pertain to the shares of SDRC Common
Stock into which their shares of CAMAX Common Stock will have been converted
pursuant to the Merger Agreement.  As soon as practicable after the
Effective Date, SDRC's stock transfer agent (the "Exchange Agent") will send
to each former CAMAX shareholder a letter of transmittal for use in
submitting to the Exchange Agent certificates (or with instructions for
handling lost CAMAX stock certificates) formerly representing shares of
CAMAX Common Stock to be exchanged for certificates representing SDRC Common
Stock (and, to the extent applicable, cash in lieu of fractional shares of
SDRC Common Stock) which the former shareholders of CAMAX are entitled to
receive as a result of the Merger.  Shareholders who become holders of SDRC
Common Stock in the Merger will not be entitled to receive any dividends or
other distributions which may be payable to holders of record of SDRC Common
Stock following the Effective Date until they have surrendered and exchanged
their certificates evidencing ownership of shares of CAMAX Common Stock. 
Any dividends payable on SDRC Common Stock after the Effective Date will be
paid to the Exchange Agent and, upon receipt of the certificates
representing shares of CAMAX Common Stock, the Exchange Agent will forward
to CAMAX shareholders (i) certificates representing their shares of SDRC
Common Stock, (ii) dividends declared thereon subsequent to the Effective
Date (without interest) and (iii) the cash value of any fractional shares
(without interest).  CAMAX'S SHAREHOLDERS ARE REQUESTED NOT TO SUBMIT STOCK
CERTIFICATES UNTIL THEY HAVE RECEIVED WRITTEN INSTRUCTIONS FROM THE EXCHANGE
AGENT TO DO SO.

At the Effective Date, the stock transfer books of CAMAX will be closed and
no transfer of CAMAX Common Stock will thereafter be made on such books. 
If a certificate formerly representing shares of CAMAX Common Stock is
presented to SDRC, it will be forwarded to the Exchange Agent for
cancellation and exchanged for a certificate representing shares of SDRC
Common Stock.

Federal Income Tax Consequences

Pursuant to the Merger Agreement, SDRC and CAMAX will receive a tax opinion
of Dinsmore & Shohl, SDRC's principal outside counsel, substantially to the
effect that the federal income tax consequences of the Merger will be as
follows:

  (a) the Merger will qualify as a tax free reorganization under
368(a)(1)(A) and 368(a)(2)(D) of the Internal Revenue Code of 1986, as
amended (the "Code") and SDRC, Acquisition Corp. and CAMAX will each be a
party to the reorganization;

  (b) no gain or loss will be recognized by SDRC, Acquisition Corp. or CAMAX
as a result of the consummation of the Merger;

  (c) no gain or loss will be recognized by a shareholder of CAMAX upon the
exchange of shares of CAMAX Common Stock for shares of SDRC Common Stock
pursuant to the Merger, except that gain or loss will be recognized by a
CAMAX shareholder on the receipt of cash in lieu of a fractional share of
SDRC Common Stock;

  (d) the adjusted tax basis of the SDRC Common Stock (including fractional
share interests deemed received) received by the CAMAX shareholders pursuant
to the Merger will be the same as the adjusted tax basis of the CAMAX Common
Stock surrendered in exchange therefor;

  (e) the holding period of SDRC Common Stock (including fractional share
interests deemed received) received by the CAMAX shareholders as a result
of the Merger will include the holding period of the shares of CAMAX Common
Stock surrendered therefor, provided that such CAMAX Common Stock is held
as a capital asset by the CAMAX shareholder at the consummation of the
Merger; and

   (f) a shareholder of CAMAX who receives cash in lieu of a fractional
shares of SDRC Common Stock will be treated as if the fractional share were
distributed as part of the exchange and then as having received a cash
distribution in redemption of such fractional share, resulting in gain or
loss upon receipt of such cash taxed as provided in Section 302 of the Code.

The above tax opinion will be based upon certain customary representations
and assumptions referred to in the opinion letter and is expressly
contingent upon satisfaction of the continuity of interest requirement of
the Treasury Regulations.  This requirement will be satisfied if the
shareholders of CAMAX receive and retain SDRC Common Stock equal in value,
as of the Effective Date, to at least 50% of the value of all of the
formerly outstanding shares of CAMAX Common Stock, as of that date.  

In addition, any cash payment to a shareholder who exercises his dissenters'
rights will be a taxable transaction.  Any cash payment received by a
dissenting holder of CAMAX Common Stock who has perfected dissenters' rights
in exchange for such shareholder's shares will be treated as having been
received as a distribution in redemption of such shareholder's shares, the
consequences of which will be determined in accordance with Section 302 of
the Code.

Because of the complexity of the tax laws, and because the tax consequences
to any particular shareholder may be affected by specific matters not common
to all shareholders, it is recommended that CAMAX shareholders consult their
personal tax advisors concerning the consequences of the Merger to them,
including the consequences of the application of state and local tax laws,
if any.

The federal income tax discussion set forth above is based on current law
but may not be specific to the situation of a particular shareholder.  Each
of CAMAX's shareholders should consult his or her own tax advisor as to the
specific tax consequences of the merger to him or her, including the
application and effect of federal, state, local and other tax laws.

Accounting Treatment

The Merger, if completed as proposed, is expected to qualify as a pooling
of interests for accounting and financial reporting purposes.  Accordingly,
under generally accepted accounting principles, as of the Effective Date,
the assets and liabilities of CAMAX will be combined with those of SDRC at
their recorded book values and the shareholders' equity account of CAMAX
will be included as such in SDRC's consolidated balance sheet.  The
financial statements of CAMAX will be combined with the financial statements
of SDRC on a retroactive basis for all prior periods.

Stock Exchange Listing

SDRC has agreed that the SDRC Common Stock to be issued pursuant to the
Merger will be approved for listing on the Nasdaq National Market, subject
to official notice of issuance.  An application will be made for listing
such SDRC Common Stock on the Nasdaq National Market.

Regulatory Approvals

Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), certain acquisition transactions may not be
consummated unless notice has been given and certain information has been
furnished to the Antitrust Division of the United States Department of
Justice (the "Antitrust Division") and the FTC and certain waiting period
requirements have been satisfied.  The Merger is subject to these
requirements.

SDRC and CAMAX each filed with the Antitrust Division and the FTC a
Notification and Report Form with respect to the Merger on February 8, 1996. 
Under the HSR Act, the Merger may not be consummated until the expiration
of a waiting period of at least 30 days following the receipt of each
filing, unless the waiting period is earlier terminated by the FTC and the
Antitrust Division.  On March  ___, 1996, notice of early termination under
the HSR Act was received by the parties.

The FTC and the Antitrust Division frequently scrutinize the legality of
transactions such as the Merger under the antitrust laws.  At any time
before or after the Effective Date, the FTC or the Antitrust Division could
take such action under the antitrust laws as it deems necessary or desirable
in the public interest, including seeking to enjoin the Merger or seeking
the divestiture of certain assets of the parties.  State Attorneys General
and private parties may also bring legal actions under the federal or state
antitrust laws under certain circumstances.  Based upon an examination of
information available to SDRC and CAMAX relating to the businesses in which
SDRC, CAMAX and their respective subsidiaries are engaged, SDRC and CAMAX
believe that the consummation of the Merger will not violate the antitrust
laws.  Nevertheless, there can be no assurance that a challenge to the
proposed Merger on antitrust grounds will not be made or, if such a
challenge is made, that SDRC and CAMAX will prevail.

Limitations on Negotiations by CAMAX

Under the terms of the Merger Agreement, CAMAX has agreed that neither
CAMAX, its subsidiaries nor their respective officers, directors, employees
or agents will initiate or hold discussions, negotiate or bargain with or
entertain offers from any other party concerning the acquisition or change
in control of CAMAX, however structured.  CAMAX has further agreed that in
the event CAMAX receives an unsolicited offer relating to the type of
transaction contemplated by the Merger Agreement, CAMAX will immediately
notify SDRC in writing of the existence and contents of such offer, the
identity of the offeror and will provide SDRC with a copy of the offer and
any related correspondence.  CAMAX has further agreed to immediately inform
any offeror of the existence of the Merger Agreement and that CAMAX will
reject any such third party offer.

Rights of Dissenting Shareholders

The following summary of the applicable provisions of Sections 302A.471 and
302A.473 of the Minnesota Business Corporation Act ("MBCA") is not intended
to be a complete statement of such provisions and is qualified in its
entirety by reference to such sections, the full texts of which are attached
as Annex C to this Proxy Statement/Prospectus. These sections should be
reviewed carefully by any holder who wishes to exercise dissenters' rights
or who wishes to preserve the right to do so, since failure to comply with
the procedures set forth herein or therein will result in the loss of
dissenters' rights.

Sections 302A.471 and 302A.473 of the MBCA provide for rights of
shareholders to dissent and obtain payment of the "fair value" of their
shares, as defined in the statute, in the event of a merger.  The procedures
for asserting dissenters' rights are set forth in such sections, the full
texts of which are reprinted as Annex C to this Proxy Statement/Prospectus. 
All references in Sections 302A.471 and 302A.473 and in this summary to a
"shareholder" are to the record holder of the Common Stock as to which
rights are asserted.  A person having beneficial ownership of CAMAX Common
Stock that is held of record in the name of another person, such as a
broker, nominee, trustee or custodian, must act promptly to cause the record
holder to follow the steps summarized below properly and in a timely manner
in order to perfect whatever dissenters' rights the beneficial owner may
have.  Shareholders who wish to assert their dissenters' rights must fully
comply with the statutory requirements in order to preserve the right to
obtain payment for their shares.  

Any shareholder who wishes to dissent and obtain payment for his or her
shares (i) must file with CAMAX, before the taking of the shareholder vote
on the Merger and the Merger Agreement at the Special Meeting, a written
notice stating the shareholder's intention to demand payment of the fair
value of his or her shares if the Merger is effectuated, and (ii) must not
vote his or her shares for adoption of the Merger and the Merger Agreement. 
Such notice must be filed at CAMAX's executive offices, 7851 Metro Parkway,
Minneapolis, Minnesota 55425, and should specify the shareholder's name and
mailing address, the number of shares of CAMAX Common Stock owned and that
the shareholder intends to demand the value of his or her shares.  This
written demand must be in addition to and separate from any proxy or vote
against the Merger and the Merger Agreement.  Voting against, abstaining
from voting or failing to vote on the Merger will not constitute a demand
for appraisal or the required written notice described in (i) above.  A
shareholder must satisfy requirement (ii) above by voting against approval
of the Merger in person at the Special Meeting or by proxy.  In addition,
a shareholder may satisfy requirement (ii) above by abstaining from voting
his or her shares.  The shareholder can so abstain by not voting in favor
of approval of the Merger and the Merger Agreement at the Special Meeting. 
 A shareholder's failure to vote against the Merger will not constitute a
waiver of dissenters' rights.  However, if a shareholder returns a signed
proxy but does not specify a vote against adoption of the Merger and the
Merger Agreement or direction to abstain, the proxy will be voted for
adoption of the Merger and the Merger Agreement, which will have the effect
of waiving that shareholder's dissenters' rights.

A shareholder of CAMAX may not assert dissenters' rights as to less than all
of the shares of CAMAX Common Stock registered in such holder's name except
where certain shares are beneficially owned by another person but registered
in such holder's name.  If a record owner, such as a broker, nominee,
trustee or custodian, wishes to dissent with respect to shares beneficially
owned by another person, such shareholder must dissent with respect to all
of such shares and must disclose the name and address of the beneficial
owner on whose behalf the dissent is made.  A beneficial owner of CAMAX
Common Stock who is not the record owner may assert dissenters' rights as
to shares held on such person's behalf, provided that such beneficial owner
submits a written consent of the record owner to CAMAX at or before the time
such rights are asserted.

After approval of the Merger and the Merger Agreement by the shareholders
at the Special Meeting, the Surviving Corporation will send a written notice
to each shareholder who filed a written demand for dissenters' rights.  The
notice will contain the address to which the shareholder must send a demand
for payment and the stock certificates in order to obtain payment and the
date by which they must be received, a form to be used in connection
therewith and other related information.

In order to receive fair value for his or her shares, a dissenting
shareholder must, within 30 days after the date such notice was given, send
his or her stock certificates and all other information specified in the
notice from Surviving Corporation to the address specified in such notice. 
A dissenting shareholder will retain all rights as a shareholder until the
Effective Date.  After a valid demand for payment, the related stock
certificates and other information are received, or after the Effective
Date, whichever is later, Surviving Corporation will remit to each
dissenting shareholder who has complied with statutory requirements the
amount Surviving Corporation estimates to be the fair value of such
shareholder's CAMAX Common Stock, with interest commencing five days after
the Effective Date at a rate prescribed by statute.  Such remittance will
be accompanied by Surviving  Corporation's closing balance sheet and
statement of income for a fiscal year ending not more than 16 months before
the Effective Date, together with the latest available interim financial
data, an estimate of the fair value of the shareholder's shares and a brief
description of the method used to reach the estimate, a brief description
of the procedure to be followed demanding supplemental payment, and copies
of Sections 302A.471 and 302A.473.

If the dissenting shareholder believes that the amount remitted by the
Surviving Corporation is less than the fair value of such holder's shares,
plus interest, the shareholder may give written notice to the Surviving
Corporation of such holder's own estimate of the fair value of the shares,
plus interest, within 30 days after the mailing date of the remittance and
demand payment of the difference.  Such notice must be given at the
Surviving Corporation's executive offices at the address set forth above. 
A shareholder who fails to give such written notice within this time period
is entitled only to the amount remitted by the Surviving Corporation.

Within 60 days after receipt of a demand for supplemental payment, the
Surviving Corporation must either pay the shareholder the amount demanded
or agreed to by such shareholder after discussion with the Surviving
Corporation or petition a court for the determination of the fair value of
the shares, plus interest.  The petition shall name as parties all
shareholders who have demanded supplemental payment and have not reached an
agreement with the Surviving Corporation.  The court, after determining that
the shareholder or shareholders in question have complied with all statutory
requirements, may use any valuation method or combination of methods it
deems appropriate to use, whether or not used by the Surviving Corporation
or the dissenting shareholder, and may appoint appraisers to recommend the
amount of the fair value of the shares.  The court's determination will be
binding on all shareholders of the Surviving Corporation who properly
exercised dissenters' rights and did not agree with the Surviving
Corporation as to the fair value of the shares.  Dissenting shareholders are
entitled to judgment for the amount by which the court-determined fair value
per share, plus interest, exceeds the amount per share, plus interest,
remitted to the shareholders by the Surviving Corporation.  The shareholders
shall not be liable to the Surviving Corporation for any amounts paid by the
Surviving Corporation which exceed the fair value of the shares as
determined by the court, plus interest.  The costs and expenses of such a
proceeding, including the expenses and compensation of any appraisers, will
be determined by the court and assessed against the Surviving Corporation,
except that the court may, in its discretion, assess part or all of those
costs and expenses against any shareholder whose action in demanding
supplemental payment is found to be arbitrary, vexatious or not in good
faith.  The court may award fees and expenses to an attorney for the
dissenting shareholders out of the amount, if any, awarded to such
shareholders.  Fees and expenses of experts or attorneys may also be
assessed against any person who acted arbitrarily, vexatiously or not in
good faith in bringing the proceeding.

The Surviving Corporation may withhold the remittance of the estimated fair
value, plus interest, for any shares owned by any person who was not a
shareholder or who is dissenting on behalf of a person who was not a
beneficial owner on January 17, 1996, the date on which the proposed Merger
was first announced to the public (the "Public Announcement Date").  The
Surviving Corporation will forward to any such dissenting shareholder who
has complied with all requirements in exercising dissenters' rights the
notice and all other materials sent after shareholder approval of the Merger
and the Merger Agreement to all shareholders who have properly exercised
dissenters' rights, together with a statement of the reason for withholding
the remittance and an offer to pay the dissenting shareholder the amount
listed in the materials if the shareholder agrees to accept that amount in
full satisfaction.  The shareholder may decline this offer and demand
payment by following the same procedure as that described for demand of
supplemental payment by shareholders who owned their shares as of the Public
Announcement Date.  Any shareholder who did not own shares on the Public
Announcement Date and who fails properly to demand payment will be entitled
only to the amount offered by the Surviving Corporation.  Upon proper demand
by any such shareholder, rules and procedures applicable in connection with
receipt by the Surviving Corporation of the demand for supplemental payment
given by a dissenting shareholder who owned shares on the Public
Announcement Date will also apply to any shareholder properly giving a
demand but who did not own shares of record or beneficially on the Public
Announcement Date, except that any such shareholder is not entitled to
receive any remittance from the Surviving Corporation until the fair value
of the shares, plus interest, has been determined pursuant to such rules and
procedures.

Shareholders considering exercising dissenters' rights should bear in mind
that the fair value of their shares determined under Sections 302A.471 and
302A.473 could be more than, the same as or, in certain circumstances, less
than the consideration they would receive pursuant to the Merger Agreement
if they do not seek appraisal of their shares, and that the opinion of any
investment banking firm as to fairness, from a financial point of view, is
not an opinion as to fair value under such Sections.

Conduct Pending Merger; Representations and Warranties

The Merger Agreement contains certain covenants of the parties which must
be performed as a condition to the parties' consummation of the Merger. 
Both SDRC and CAMAX have agreed to cooperate with each other; allow access
to each of their business operations, corporate information and personnel,
and use reasonable efforts to cause the Merger to qualify for pooling of
interests accounting.  CAMAX has further agreed to the following:  (i) until
the Effective Date, CAMAX will conduct its business in the ordinary course
and will refrain from making any individual disbursements or commitments in
excess of $150,000 subject only to planned disbursements or those made in
accordance with CAMAX's Bonus Plan; (ii) all of CAMAX's subsidiaries will
be wholly-owned by CAMAX or Point Control Co.; (iii) until the Effective
Date and except for the valid exercise of options granted under the CAMAX
Option Plans or the CAMAX Non-Qualified Options, CAMAX's capital structure
will not change, nor will CAMAX pay any dividends or make any distributions
on its stock, without SDRC's prior written consent; (iv) until the Effective
Date, CAMAX will not negotiate with any other party concerning the
acquisition or change of control of CAMAX; (v) CAMAX will not grant any new
options under the CAMAX Option Plans or otherwise; (vi) CAMAX will call a
meeting of its shareholders for the purpose of voting on the Merger and the
Merger Agreement; (vii) CAMAX must use its best efforts to cause its
directors, officers and affiliates not to sell any shares of SDRC Common
Stock until it is legally appropriate to do so; and (viii) CAMAX will make
available to SDRC for review certain of its tax files and returns.

In addition, SDRC has agreed to the following:  (i) SDRC will prepare and
file registration statements to register its stock to be issued in the
Merger and the stock to be issued on the exercise of options; (ii) SDRC may
continue or terminate CAMAX's employee benefit plans, but such plans will
continue in force until terminated and SDRC will honor previously vested
rights and credits for service under CAMAX's employee benefit plans; (iii)
SDRC will file all reports with the Commission necessary to allow CAMAX
shareholders who are deemed affiliates to sell their SDRC Common Stock; (iv)
SDRC will indemnify CAMAX's or its Subsidiaries' officers, directors or
employees for acts or omissions which occurred prior to the Effective Date
to the extent such indemnification would be required under Minnesota law;
(v) SDRC will provide CAMAX with copies of all Commission reports and
filings; and (vi) listing on Nasdaq National Market the shares of SDRC
Common Stock to be issued in the Merger.

SDRC, Acquisition Corp. and CAMAX have also made numerous representations
and warranties to each other with respect to financial and other matters. 
These include, without limitation, representations and warranties to the
effect that both SDRC and CAMAX have the corporate power and authorization
to enter into the proposed transaction, that each will have provided the
other with financial statements, and that SDRC has enough authorized SDRC
Common Stock with which to accomplish the proposed transaction.  CAMAX also
represented and warranted, without limitation, that (i) it has good title
to its assets and properties and that its leases are in order; (ii) there
are no undisclosed violations of ERISA, tax, securities, environmental laws
or other laws; (iii) it has made full disclosure of all of CAMAX's
inventory, contracts, intellectual property, insurance policies, bank
matters, employee benefit plans, employee matters and international business
matters; (iv) CAMAX has appropriate intellectual property protections; and
(v) CAMAX has received a fairness opinion and tax opinion in connection with
the Merger.  SDRC and Acquisition Corp. also represented and warranted that
(i) they had completed their due diligence of CAMAX; (ii) they had delivered
to CAMAX copies of all of their periodic reports prepared and filed with the
Commission pursuant to the Exchange Act, and that such reports are complete
and accurate; (iii) except as disclosed, there has been no material adverse
change in SDRC's business; and (iv) to SDRC's knowledge, neither it nor
Acquisition Corp. has taken or agreed to take any actions which would
prevent the Merger from qualifying as a tax free transaction.

No representations or warranties made by either CAMAX or SDRC and
Acquisition Corp. will survive beyond the Retention Period described in the
Escrow Agreement.  Thereafter, neither CAMAX, SDRC, Acquisition Corp. nor
any officer or director of any of them will have any liability or obligation
with respect to such representations or warranties, with the exception of
any misrepresentations, breaches of warranties or violations of covenants
that were made with intent to defraud. See "Annex A - Agreement of Merger
and Plan of Reorganization." 

Where any of the representations and warranties of CAMAX or other covenants
and conditions are qualified in the Merger Agreement by "knowledge" or "best
knowledge," such term has been defined in the Merger Agreement to mean the
actual knowledge of the current members of the board of directors and
officers through and including the vice president level of CAMAX and its
subsidiaries, as that knowledge has been obtained in the normal conduct of
business and following a reasonable investigation by such individuals.  In
the Merger Agreement, where the term "Material Adverse Effect" is used to
qualify a representation and warranty, covenant or condition with respect
to any party, it means any single or a series of related conditions, events,
changes or occurrences that have or may reasonably be expected to have a
financially adverse effect on the business, operations, results of
operations and/or financial condition of such party and its subsidiaries,
if taken as a whole, in the amount of $125,000 or more.

of the shares of CAMAX Common Stock outstanding on the Record Date.

In addition, the obligations of CAMAX and SDRC to consummate the Merger are

Amendment; Termination

The Merger Agreement may be amended, modified or supplemented by the written
agreement of each of the parties, upon the authorization of each company's
respective Board of Directors and without further approval of CAMAX's
shareholders, except that no amendment, modification or supplement may be
effected without CAMAX shareholder approval if to do so would violate any
applicable provisions of law.

The Merger Agreement may be terminated and the Merger abandoned at any time

Effect on CAMAX Employees

SDRC intends to employ some number of the employees of CAMAX but is not
obligated to do so.  In this regard, SDRC shall, prior to the Effective
Date, identify those employees of CAMAX to be retained by SDRC subsequent
to the Effective Date.  After the Effective Date, pursuant to the Merger
Agreement, SDRC will have the right to continue, amend or terminate any or
all of the CAMAX employee benefit plans ("Benefit Plans") in accordance with
their terms and applicable law; however, until SDRC takes such action, the
Benefit Plans will continue in force for the benefit of any CAMAX employees
who have any present or future entitlement to benefits under such Benefit
Plans.  SDRC will honor the obligations of CAMAX with respect to vested
rights under Benefit Plans and agreements of CAMAX relating to CAMAX
employees in accordance with the terms of such vested rights.  SDRC will
also credit all employees of CAMAX and its Subsidiaries with all service
with CAMAX and its Subsidiaries for purposes of eligibility to participate,
eligibility for benefits, calculation of benefits and vesting under any of
Surviving Corporation's or SDRC's existing or future employee benefit plans,
programs or arrangements under which the right to or the amount of benefits
is based on the service of such employees.  See "Interests of Certain
Persons in the Merger" herein.

Interests of Certain Persons in the Merger

The Board of Directors of CAMAX was aware of the interests of certain
persons in the Merger described below and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby. 

CAMAX's Directors and Officers.  Acquisition Corp. will be the Surviving
Corporation of the Merger, will change its name to CAMAX Manufacturing
Technologies, Inc, an Ohio corporation, and will be a wholly owned
subsidiary of SDRC upon consummation of the Merger.  The directors of
Acquisition Corp. immediately prior to the Effective Date will continue as
the directors after the Effective Date, and the officers of Acquisition
Corp. immediately prior to the Effective Date will continue as the initial
officers of Surviving Corporation after the Effective Date.  After the
Effective Date, no current officer or director of CAMAX will remain as an
officer or director of Surviving Corporation.

Stock Options.  The Agreement provides that outstanding options issued
pursuant to the CAMAX Option Plans and the CAMAX Non-Qualified Options
(including options held by CAMAX's executive officers and directors) will
be exercisable for shares of SDRC Common Stock after the Effective Date of
the Merger.  Of the ___________ options outstanding on the Record Date,
__________ were held by Mr. Majteles, __________ were held by Mr. Furness
and __________ were held by other directors and officers of CAMAX.

Indemnification of Directors and Officers.  SDRC has agreed that, from and
after the Effective Date, SDRC and Surviving Corporation will indemnify each
person who is at the Effective Date, or has been at any time prior to the
Effective Date, an officer, director or employee of CAMAX or any of the
Subsidiaries, for judgments, penalties, fines, including, without
limitation, excise taxes against such officers, directors or employees, with
respect to an employee benefit plan settlement, and reasonable expenses,
including attorneys' fees and disbursements, incurred by such person in
connection with a proceeding, to the extent such indemnification would be
required under Section 302A.521 of the MBCA as in effect on the Effective
Date.

Employment Offer Letters.  In connection with the Merger, SDRC has entered
into letter agreements (the "Offer Letters") with Mr. Furness, all Vice
Presidents of CAMAX and the Controller of CAMAX concerning each such
individual's employment with SDRC following the Merger.  The Offer Letters
provide for a severance payment to each of the Vice Presidents and
Controller of CAMAX equal to one-year's salary if such employee is
terminated other than for cause during the first 24 months following the
Effective Date.  Mr. Furness's Offer Letter states that he will be employed
through December 31, 1996, unless earlier terminated by SDRC, and at that
time, if his employment is not continued with SDRC and provided he is not
terminated for cause, he shall be entitled to a severance payment equal to
18 months' salary.  The Offer Letters also state that Mr. Furness, the Vice
Presidents and the Controller of CAMAX will be employed by SDRC at their
current salary and be entitled to participate in a management bonus plan
similar to the plan each such employee participated in during 1995.

Severance Arrangement.  Following the Merger, Mr. Majteles will not be
employed by SDRC or the Surviving Corporation.  SDRC has agreed to offer Mr.
Majteles, upon consummation of the Merger, the following severance package:
(i) SDRC will ratify the payment to Mr. Majteles of the maximum executive
bonus award by CAMAX for the year ended December 31, 1995 which is estimated
to be $80,000, (ii) SDRC will ratify payment to Mr. Majteles of a lump sum
severance payment equal to three years of Mr. Majteles' current annualized
base pay amount of $135,000, (iii) SDRC will ratify payment to Mr. Majteles
of a lump sum of $17,300 for use in obtaining the assistance of a reputable
executive out-placement firm, (iv) SDRC has agreed to engage Mr. Majteles
as a consultant for a period of six months following the Effective Date for
consideration of $11,250 per month, and (v) SDRC has agreed to compensate
Mr. Majteles at the rate of $11,250 per month for his agreement not to
compete with SDRC in the CAD/CAM/CAE marketplace for 24 months.

CAMAX's Financial Advisors

WA&H has acted as financial advisor to CAMAX in connection with the Merger. 
Pursuant to an engagement letter dated November 10, 1995 (the "Engagement
Letter"), CAMAX retained WA&H to furnish financial advisory and investment
banking services with respect to a possible sale or merger of CAMAX and to
render an opinion as to the fairness, from a financial point of view, to the
CAMAX shareholders of the consideration offered in any proposed sale or
merger.  The amount of consideration to be received by CAMAX shareholders
in the Merger was determined through negotiations between CAMAX management
and SDRC and not by WA&H, although WA&H did assist CAMAX management in these
negotiations.

WA&H is a nationally recognized investment banking firm and is regularly
engaged in the valuation of businesses and securities in connection with
mergers and acquisitions, negotiated underwritings, secondary distributions
of listed and unlisted securities, private placements and valuations for
corporations.  

Pursuant to the Engagement Letter, CAMAX has agreed to pay WA&H, upon
consummation of the Merger, a transaction fee (the "Transaction Fee") of 
$250,000.  Also pursuant to the Engagement Letter, CAMAX paid WA&H a
nonrefundable retainer fee (the "Retainer Fee") of $25,000 upon execution
of the Engagement Letter and a nonfundable opinion fee (the "Opinion Fee")
of $125,000 upon the rendering of WA&H's opinion.   The Retainer Fee and the
Opinion Fee will be credited against the Transaction Fee.  Payment of the
Transaction Fee is contingent upon consummation of the Merger.  CAMAX has
also agreed to reimburse WA&H for its reasonable out-of-pocket expenses, up
to $15,000, and to indemnify WA&H against certain liabilities relating to
or arising out of services performed by WA&H as financial advisor to CAMAX. 
The terms of the Engagement Letter, which are customary in transactions of
this nature, were negotiated at arm's length between CAMAX and WA&H, and the
CAMAX Board of Directors was aware of such fee arrangement at the time of
its approval of the Merger Agreement.

Opinion of Wessels, Arnold & Henderson

WA&H rendered its oral opinion (subsequently confirmed in writing on January
16, 1996) on January 13, 1996 to the CAMAX Board of Directors that, as of
such date and based on the procedures followed, factors considered and
assumptions made by WA&H as set forth therein, the consideration to be
received by the holders of CAMAX Common Stock pursuant to the Merger
Agreement is fair from a financial point of view to the holders of CAMAX
Common Stock.  A copy of the WA&H opinion dated as of the date of this Proxy
Statement/Prospectus (the "Wessels Opinion"), which sets forth the
assumptions made, factors considered, the scope and limitations of the
review undertaken and the procedures followed by WA&H is attached to this
Proxy Statement/Prospectus as Annex B.  CAMAX shareholders are urged to read
the Wessels Opinion in its entirety.  The summary of the Wessels Opinion set
forth herein is qualified in its entirety by reference to the Wessels
Opinion.  The Wessels Opinion applies only to the fairness of the
consideration to be received by the CAMAX shareholders as provided by the
terms of the Merger Agreement and should not be deemed to constitute a
recommendation by WA&H to CAMAX shareholders to vote in favor of any matter
presented in this Proxy Statement/Prospectus.  CAMAX  shareholders should
note that the opinion expressed by WA&H was provided solely for the use of
the CAMAX Board of Directors in its evaluation of the Merger and was not on
behalf of, and was not intended to confer rights or remedies upon SDRC, any
securityholder of SDRC or CAMAX, or any person other than CAMAX's Board of
Directors.  The CAMAX Board of Directors did not impose any limitations on
the scope of the investigation of WA&H with respect to rendering its
opinion.

In connection with its review of the Merger, and in arriving at its opinion,
WA&H has:  (i) reviewed and analyzed the financial terms of the Merger
Agreement and various related documents, (ii) reviewed and analyzed certain
historical and projected financial statements of CAMAX provided by CAMAX's
management, (iii) reviewed and analyzed certain historical and projected
financial statements provided by SDRC's management, (iv) reviewed and
analyzed certain historical business and financial information relating to
both CAMAX and SDRC, (v) conducted discussions with members of the senior
management of CAMAX and SDRC with respect to the business prospects of CAMAX
and SDRC, (vi) reviewed and analyzed certain other information related to
the Merger, (vii) reviewed the financial terms, to the extent publicly
available, of certain comparable merger transactions, and (viii)
participated in discussions and negotiations among representatives of CAMAX
and SDRC and their respective financial and legal advisors.

Based on this information, WA&H performed a variety of analyses and
examinations of the Merger and considered such financial, economic and
market criteria as it deemed necessary in arriving at its opinion.  The
following is a summary of the financial analyses performed by WA&H in
connection with the delivery of the Wessels Opinion.

Comparable Company Analysis.  WA&H used a comparable company analysis to
analyze CAMAX's operating performance relative to a group of publicly traded
companies which WA&H deemed for purposes of its analysis to be comparable
to CAMAX.  In such analysis, WA&H compared multiples of selected financial
data for CAMAX with those of the following publicly traded companies in the
technical software industry: Autodesk, Inc., MacNeal-Schwendler Corporation,
Parametric Technology Corporation, Softdesk, Inc. and SDRC (collectively,
the "Comparable Companies").  Although such companies were considered
comparable to CAMAX for the purpose of this analysis based on certain
characteristics of their respective businesses, none of such companies
possessed characteristics identical to those of CAMAX.  WA&H calculated the
following valuation multiples based on, as to CAMAX, $32,600,000 (which
assumes as of the date of the Wessels Opinion, the exercise of all options
issued pursuant to the CAMAX Option Plans and the CAMAX Non-Qualified
Options, except the unvested options held by Mr. Majteles) to be offered as
consideration in the Merger, and, as to the Comparable Companies, on market
prices and other information available as of the date of the Wessels
Opinion.  Multiples of future earnings were based on projected earnings as
estimated publicly by recognized securities analysts.  The mean and median
for market capitalization as a multiple of each of the indicated statistics
for CAMAX and the Comparable Companies is as follows: (i) projected calendar
year 1995 earnings per share, 33.4x for CAMAX as compared to a mean of 26.0x
and a median of 17.7x for the Comparable Companies, and (ii) projected
calendar year 1996 earnings per share, 16.7x for CAMAX, as compared to a
mean of 17.8x and a median of 14.3x for the Comparable Companies.   In each
of the comparisons of the value to be achieved by the CAMAX shareholders in
the Merger as compared to the mean and median of the market values realized
by the shareholders of the Comparable Companies, the multiples of operation
results achieved by the CAMAX shareholders was approximately equal to that
realized by the shareholders of the Comparable Companies.

Comparable Transactions.  WA&H compared multiples of selected financial data
and other financial data relating to the proposed Merger with multiples paid
in, and other financial data from, 10 selected acquisitions ("Comparable
Transactions") since 1991 of technical software companies (i.e., companies
in the markets for computer-aided design, computer-aided engineering and
electronic design automation software).  The Comparable Transactions were
selected based primarily on the target company's involvement in the
technical software industry.  WA&H calculated the following valuation
multiples based on $32,600,000 to be offered as consideration in the Merger,
and, as to the Comparable Transactions, on the consideration paid to the
target company.  Multiples of latest twelve month revenue, latest twelve
month operating income and latest twelve month net income, were based on
data provided by Securities Data Corporation and WA&H.  The mean and median
for the value of the transaction as a multiple of each of the indicated
statistics for CAMAX and the Comparable Transactions is as follows: (i)
latest twelve months revenue, 1.6x for CAMAX as compared to a mean of 4.5x
and a median of 3.2x for the Comparable Transactions, (ii) latest twelve
months operating income, 22.0x for CAMAX, as compared to a mean of 33.8x and
a median of 23.5x for the Comparable Transactions, (iii) latest twelve
months net income, 33.4x for CAMAX as compared to a mean of 50.3x and a
median of 40.7x for the Comparable Transactions.  WA&H then compared the
multiple of operating income and the multiple of net income for each of the
selected transactions to the estimated growth rate for each target company
at the time of the transaction. The mean and median for the value of the
multiple of operating income divided by the company's estimated growth rate
for CAMAX and the Comparable Transactions is 1.5x for CAMAX as compared to
a mean of 1.3x and a median of 1.2x for the Comparable Transactions.  The
mean and median for the value of the multiple of net income divided by the
estimated growth rate for CAMAX and the Comparable Transactions is 2.2x for
CAMAX as compared to a mean of 1.9x and a median of 1.5x for the Comparable
Transactions.

Discounted Cash Flow Analysis.  WA&H estimated present values of CAMAX using
a discounted cash flow analysis based on projections of future operations
prepared by CAMAX's management.  WA&H calculated present values of projected
operating cash flows after net changes to working capital over the period
between March 31, 1996 and December 31, 1999 using discount rates ranging
from 14% to 22%.  WA&H calculated approximate terminal values of CAMAX as
of December 31, 1999 of 7.5x CAMAX's calendar year 1999 operating income. 
WA&H determined this multiple by analyzing the relationship between the
Comparable Companies' current projected growth rate and the Comparable
Companies' projected 1996 operating income multiple and applying this
relationship to CAMAX's estimated future growth rate as of 1999.  The
terminal value was discounted to present value using the same discount rates
as the cash flows.  WA&H calculated an implied valuation of CAMAX by adding
the present value of the cash flows and the terminal value and then applying
a 30% discount to reflect the fact that CAMAX Common Stock is privately held
and therefore less liquid than stock of comparable publicly-held companies. 
The implied value of CAMAX based on this analysis ranged from $18,431,000
to $32,108,000.  WA&H determined that, at the time of the Wessels Opinion,
the value of the consideration to be received by the CAMAX  shareholders in
the Merger of $32,600,000 was greater than the present value of CAMAX's cash
flows under the range of discounted cash flow valuations discussed above.

The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description.  WA&H
believes that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all factors and analyses, could create an incomplete or
misleading view of the processes underlying its opinion.  In arriving at its
fairness determination, WA&H considered the results of all such analyses. 
In view of the wide variety of factors considered in connection  with its
evaluation of the fairness of the consideration to be received by the
shareholders of CAMAX in the Merger, WA&H did not find it practicable to
assign relative weights to the factors considered in reaching its opinion. 
No company or transaction used in the above analysis as a comparison is
identical to CAMAX or SDRC or the proposed Merger.  The analyses were
prepared solely for purposes of WA&H providing its opinion as to the
fairness of the Merger consideration pursuant to the Merger Agreement to
CAMAX and do not purport to be appraisals or necessarily reflect the prices
at which businesses or securities actually may be sold.  Analyses based upon
forecast of future results are not suggested by such analyses.  As described
above, the Wessels Opinion and presentation to the CAMAX Board of Directors
was one of the many factors taken into consideration by the CAMAX Board of
Directors in making its determination to approve the Merger and the Merger
Agreement.

WA&H assumed and relied upon the accuracy and completeness of the financial,
legal, tax, operating and other information provided by CAMAX and SDRC and
did not independently verify such information.  Further, WA&H assumed that
the Merger will be accounted for as a pooling of interests.  WA&H did not
perform an independent evaluation or appraisal of any of the respective
assets or liabilities of CAMAX.  With respect to financial forecasts, WA&H
assumed that these forecasts were reasonably prepared on bases reflecting
the best currently available estimates and judgments of the management of
CAMAX and SDRC, as the case may be, as to the respective future financial
performance of CAMAX and SDRC.  The Wessels Opinion was based on the
conditions as they existed and the information available to WA&H on the date
of the opinion.  Events occurring after the date of the Wessels Opinion may
materially affect the assumptions used in preparing the WA&H Opinion. 
Further, the Wessels Opinion speaks only as of the date thereof and is based
on the conditions as they existed and information with which WA&H was
supplied as of the date thereof.

The full text of the opinion of Wessels, Arnold & Henderson, L.L.C., a copy
of which is attached as Annex B to this Proxy Statement/Prospectus, includes
certain qualifications and assumptions made, matters considered and
limitations on the reviews undertaken.  The summary and description of the
opinion of Wessels, Arnold & Henderson, L.L.C. contained herein are
qualified in their entirety by reference to the full text of the opinion,
and it is recommended that holders of CAMAX Common Stock read such opinion
in its entirety. 

Effects of Merger

Upon consummation of the Merger, CAMAX will merge with and into Acquisition
Corp. which will change its name to CAMAX Manufacturing Technologies, Inc.,
and CAMAX will cease to exist as a separate entity.

The Board of Directors of SDRC and Surviving Corporation after the Merger
is consummated will consist of all of the members of the Boards of Directors
of SDRC and Acquisition Corp. for the term for which such directors were
elected, subject to each company's Codes of Regulations and in accordance
with law.  The officers of SDRC and Surviving Corporation after the Merger
is consummated will be those officers of SDRC and Acquisition Corp.,
respectively, who are in office at the Effective Date, subject to each
company's Codes of Regulations and in accordance with law.


RESALE OF SDRC COMMON STOCK ISSUED IN THE MERGER

No restrictions on the sale, pledge, transfer or other disposition of the
shares of SDRC Common Stock issued pursuant to the Merger will be imposed
solely as a result of the Merger, other than restrictions on the transfer
of such shares issued to any CAMAX shareholder who may be deemed to be an
"affiliate" of SDRC or CAMAX for purposes of Rule 145 promulgated under the
Securities Act.  Directors, executive officers or holders of 10% or more of
the outstanding shares of CAMAX Common Stock may be deemed to be affiliates
of CAMAX for purposes of Rule 145.  Affiliates may not sell, pledge,
transfer or otherwise dispose of the shares of SDRC Common Stock issued to
them in exchange for their shares of CAMAX Common Stock, unless the
requirements of Rule 145(d) are satisfied or the sale, pledge, transfer or
disposition is otherwise in compliance with the Securities Act and the rules
and regulations promulgated thereunder.  Generally, under Rule 145(d), an
affiliate of CAMAX will be permitted to sell, pledge, transfer or otherwise
dispose of his or her shares of SDRC Common Stock received pursuant to the
Merger if one of the following is satisfied:

(1)  The shares are sold in "broker's transactions" or in transactions
directly with a "market maker."  The affiliate does not solicit or arrange
for the solicitation of purchase orders or make any payments in connection
with the sale to anyone other than the broker or market maker, and the
number of shares sold, together with all other sales of SDRC Common Stock
by such affiliate within the preceding three months, does not exceed one
percent of the outstanding shares of SDRC Common Stock; or

(2)  The affiliate is not an affiliate of SDRC and has been the beneficial
owner of the SDRC Common Stock for at least two years, and there is certain
publicly available information regarding SDRC.

In addition, shares of SDRC Common Stock issued to affiliates in the Merger
may not be sold, pledged, transferred or otherwise disposed of until such
time as financial results covering at least 30 days of combined operations
of SDRC and CAMAX have been published within the meaning of Section 201.01
of the Commission's Codification of Financial Reporting Policies.

Share certificates for SDRC Common Stock issued to affiliates of CAMAX will
bear a legend as follows:

The shares of stock evidenced by this certificate are subject to
restrictions on transfer and may only be transferred after the Issuer has
received an opinion from its counsel that the transfer will be in compliance
with the requirements of Rule 145(d) promulgated under the Securities Act
of 1933.  The Issuer will mail a copy of Rule 145(d) to the shareholder
without charge within five (5) days after written request therefor.

The foregoing is only a general statement of the restrictions on the
disposition of the shares of SDRC Common Stock to be issued in the Merger. 
Accordingly, those shareholders of CAMAX who may be affiliates of CAMAX
should confer with legal counsel with respect to the resale restrictions.


                STRUCTURAL DYNAMICS RESEARCH CORPORATION

Description of Business

SDRC is a leading international supplier of mechanical design automation
software and engineering services used by manufacturers for the design,
analysis, testing and manufacturing of mechanical products.  SDRC is also
a leader in product data management ("PDM") systems, which provide a
comprehensive approach to the management and control of engineering
information.  SDRC's products and services significantly reduce product
development time and cost, resulting in superior product quality by enabling
customers to optimize product designs prior to production.

SDRC was incorporated under the laws of the State of Ohio in 1967.  During
the past five years, it has restructured certain aspects of its business. 
In 1994, SDRC and Siemens Nixdorf Informationssysteme AG (SNI) formed a
joint venture, SDRC Software and Services GmbH, to supply mechanical
CAE/CAD/CAM software and services in Central Europe.  In 1992, SDRC and
Control Data Systems, Inc. established a joint venture company, Metaphase
Technology, Inc., to market product data management software.  In 1989, SDRC
and Nissan Motor Co., Ltd. established a Japanese joint venture company,
ESTECH Corporation, to provide engineering services in Japan and the Far
East. 

At December 31, 1995, SDRC and its subsidiaries had consolidated assets of
$193.5 million, consolidated liabilities of $116.1 million and consolidated
shareholders' equity of $77.4 million.

Software Products and Services

Software Products.  SDRC's primary software products are a comprehensive
software system for mechanical design automation ("MDA") marketed under the
I-DEAS Master Series (TM) name and PDM software marketed under the Metaphase
Series 2 name.  These products allow members of products development teams
to design and optimize a product concept and then track and manage data
associated with such a product throughout the development process.  

I-DEAS (Integrated Design Engineering Analysis Software) Master Series (TM)
("I-DEAS") is a family of tightly-integrated software modules that automate
the entire mechanical product development process.  I-DEAS is one of the
most widely used mechanical design automation software tools in the
industry, with more than 127,000 I-DEAS software licenses in use at more
than 14,000 customer sites worldwide.

I-DEAS allows manufacturers to design, simulate, test and optimize
manufacturing and prototype product concepts in a fraction of the time
required using standalone or partially integrated software tools.  With I-DEAS,
users are able to create and view a "master model," a solid
representation of a product that precisely defines its geometry and material
characteristics.  This master model is easily understood by everyone
concerned with the product, including representatives from management,
marketing and manufacturing.  It can be analyzed to evaluate the mechanical
performance and structural integrity of the design concept, as well as
provide information that can be used to optimize product performance.

Metaphase Series 2 tracks and manages data associated with a product
throughout its development process.  Metaphase Series 2 is based on the
product line of Metaphase Technology, Inc.  Metaphase Series 2 is a modular
PDM system designed to provide the depth and breadth of functionality users
require to meet current and future data management needs.  The software
assists users to improve the way they create, share, access, define,
manufacture and support their products.  

Services.  SDRC also provides customers with technical applications software
support and maintenance, technical support, training and consulting
services.  Technical applications software support and maintenance service
provides telephone "hotline" support, software maintenance corrections for
licensed I-DEAS products, products and features as well as enhancement
versions released during the term of the contract, and documentation updates
to support new vendor hardware and other services that enhance and maintain
the customer's I-DEAS software investment.

SDRC provides basic training for each major I-DEAS software package. 
Advanced training classes are offered for selected I-DEAS applications to
support continued growth of customer skills and to increase the productivity
of departments utilizing I-DEAS.

Building on its extensive knowledge of mechanical design automation
technology and engineering applications, SDRC also provides engineering
consulting services to improve the design of its customers' products, as
well as to improve its customers' development process.  In addition,
advanced training and technology transfer are provided to customers to
enable them to integrate and optimize their mechanical design automation
investment.  Advance computer simulation methods and in-depth application
expertise are utilized for traditional or highly specialized computer
technologies including design audits, product design, troubleshooting and
engineering process design.

Legal Proceedings

Except for the following matters, SDRC is not a party to any litigation
other than ordinary routine litigation incidental to its business. 
Beginning in September 1994 a total of 12 class action lawsuits alleging
various violations of the federal securities laws and two derivative
lawsuits alleging breaches of Ohio corporate law were filed against SDRC
following SDRC's public disclosure of certain accounting irregularities. 
All of the complaints sought unspecified damages.  The class action cases
were consolidated into one case entitled In Re: Structural Dynamics Research
Corporation Securities Litigation, United States District Court, Southern
District of Ohio, Consolidated Master File No. C-1-94-630 (the "Class Action
Case").  Subsequently, the two derivative cases were consolidated into one
case entitled In Re: Structural Dynamics Research Corporation Derivative
Litigation, United States District Court, Southern District of Ohio,
Consolidated Master File No. C-1-94-650 (the "Derivative Case").

The Class Action Case represents a direct claim against SDRC by certain
named plaintiffs acting on behalf of a class of plaintiffs consisting of
certain purchasers of SDRC's common stock between February 3, 1992 and
September 14, 1994.  In December 1995, SDRC and plaintiffs' counsel in the
Class Action Case entered into a Memorandum of Understanding setting forth
the terms of a proposed settlement of this case.  Pursuant to the proposed
settlement, SDRC will establish a settlement fund of $27.6 million
consisting of $17.6 million cash and $10 million in shares of SDRC Common
Stock (to be valued based on market prices at the time of distribution). 
The settlement is subject to final approval of the United States District
Court which has not yet been obtained.

The Derivative Case remains pending.  The legal theory of derivative
litigation is that the named plaintiffs, who are shareholders of the
corporation, are pursuing claims on behalf of the corporation against third
parties whose actions have injured the corporation but against whom the
corporation has refused to take independent action.  In such litigation the
corporation is considered a "nominal" defendant.  In the Derivative Case,
SDRC is therefore a "nominal" defendant.  The "real" defendants consist of
various former officers and employees of SDRC and certain of its directors. 
Since the plaintiffs are theoretically acting on behalf of SDRC, any
recovery in this matter would be for the benefit of SDRC.  However, SDRC
could nevertheless face exposure to liability through the legal obligation,
which could be applicable under certain circumstances, to indemnify and hold
harmless certain of the defendants against whom a judgment might be
rendered.  Although there can be no assurance as to the ultimate outcome of
this matter, SDRC management does not believe it will have a material
adverse impact on the financial condition of SDRC.

Based on the same facts which gave rise to the Class Action Case and the
Derivative Case, the Commission commenced a formal, private investigation
of SDRC  in September 1994 which remains pending.  SDRC is fully cooperating
with this investigation but cannot predict its outcome. 

During 1994 and 1995 SDRC carried $5 million of primary directors and
officers liability insurance coverage from the Federal Insurance Company
plus "excess liability coverage" from Agricultural Excess and Surplus
Insurance Company ("AESIC"), which provides $3 million of such coverage, and
from Old Republic Insurance Company ("Old Republic"), which provides an
additional $2 million of such coverage.  The directors and officers
liability insurance, both primary and excess, is potentially available with
respect to the Class Action Case and the Derivative Case because certain of
SDRC's directors and former officers are personal defendants in those
matters.  Coverage under the excess policies is dependent upon first
exhausting the primary coverage.  SDRC has come to an understanding with the
primary insurer with respect to its coverage, but the excess carriers have 
to date denied coverage.  On October 11, 1995, SDRC and certain officers and
directors named in the Class Action Case and/or the Derivative Case filed
a declaratory judgment action against the excess carriers in a case entitled
Structural Dynamics Research Corporation, et al. v. Agricultural Excess and
Surplus Insurance Company, et al., Clermont County Court of Common Pleas,
Case No. 95-CV-9697.  The action alleges that neither AESIC nor Old Republic
is entitled to rescind its policy or exclude any of the named plaintiffs
from coverage with respect to claims in the Class Action Case or the
Derivative Case.  AESIC and Old Republic each responded and have taken the
position that they are entitled to rescission and that all claims are
excluded under the terms of the policy.  While SDRC intends to vigorously
pursue this case, there can be no assurance as to its ultimate outcome.

              CAMAX MANUFACTURING TECHNOLOGIES, INC.

CAMAX originated as a division of National Computer Systems, Inc. in 1977
and was incorporated as a Minnesota corporation in 1981 under the name
CompuTool Corporation.  Today, CAMAX is the largest company in the world
focused exclusively on the development and support of CAM software for
computerized numerical control ("CNC") applications.  CAMAX develops and
markets software designed to enhance the craftsmanship of its customers,
increase the speed of manufacturing and lower the cost of NC processes.

The CAD/CAM Industry

When CAMAX originated, the computer-aided-design-and-manufacturing
("CAD/CAM") industry was in its infancy, and all design through
manufacturing-related tasks performed with a computer, with the exception
of material resource planning applications, was considered CAD/CAM.  As the
CAD/CAM market developed, increasingly more software capabilities fell
within the general category of CAD/CAM, to the extent that a need for
differentiation created the additional category of CAE. Further development
of the market, combined with competitive forces in the manufacturing
industry, drove the need to catalog, store, and associate CAD/CAM/CAE data
related to single products or assemblies of parts, giving birth to yet
another computerized application for PDM.  What was once CAD/CAM has grown
to become CAD/CAM/CAE and PDM.  Today, the industry includes a broad range
of software products to facilitate design, analysis and manufacturing for
the mechanical, architectural, civil and electrical engineering disciplines.

Engineers, designers, draftsmen, and programmers use CAD/CAM/CAE software
products to create models of products, structures, assemblies, parts and
processes.  These models can then be viewed on a graphics display screen and
used to generate performance analysis, documentation and processing
instructions.  All related data is interrelated, linked and updated with PDM
software.  The economic benefits which have led to the growth of the
CAD/CAM/CAE and PDM industry include:

(1) Generation of accurate digital model descriptions of the designed
objects which can subsequently be easily accessed for reference, change, and
transfer to other locations.

(2) Simulations and tests of performance characteristics can be conducted
so that optimized performance of the modeled objects and manufacturing
materials can be determined without the time and cost of producing
prototypes.

(3) Databases cataloging many products and instructions can be utilized for
subsequent projects to eliminate or reduce duplicative effort.

(4) Revision of an element of a part or assembly can be made with an
immediate, corresponding revision to all affected parts or assemblies.

(5) Transfer of the processing and machining data to production machines can
be accomplished to provide a closer association between production and
material resource requirements, to reduce time and costs and to improve
quality.

CAD, in its simplest form, can be described as the software that allows
users to draw, on-screen, the equivalent of paper blueprints. In its more
advanced form, CAD allows developing 3-dimensional ("3-D") models of the
subject.  By itself, the greatest benefit of CAD is the time savings
provided when a revision is required or when a similar part or product is
to be created.  In conjunction with other software, the benefits can be
multiplied.

CAE is the broad category of analysis tools, typically used by mechanical
engineers to analyze material composition, stress, flow  and temperature
dynamics.  CAE software normally uses a CAD-generated model and applies
physical construction and ambient conditions to the model for analysis.  As
a result of analysis, the material selected for the product to be
manufactured could be changed.  Often the shape of a part, the shape of a
part feature or the location of part features requires changing.  Changes
are made on the model with the CAD software. The benefit that CAE software
provides is the ability to test materials, parts and assemblies under
various conditions to determine the best construction and materials for
given specifications, requirements or conditions, without having to build
or manufacture parts, assemblies or constructions.  

CAM is generally described as the broad category of software that is used
to drive manufacturing equipment or processes, and to disseminate, collect
and archive data to, on and from shop floor equipment and personnel.  Most
often, CAM is used to describe software that generates NC instructions for
numerical control or CNC machine tools, other terms being used for better
defining specific shop-floor related software applications.

NC/CNC machine tools were developed to accelerate manufacturing through a
level of automation that reduces human error and that provides increased
consistency among parts.  Historically, production of complex tools, parts,
dies, and molds has required individual machining by a skilled machinist. 
The scarcity of skilled machinists contributes to the cost and delay
involved in complex machining operations.  NC machines have enabled the
partial automation of these machining tasks.  NC machines read preprogrammed
instructions and perform motions according to those instructions in the
proper order.  CNC machines extend this concept one step further by using
internal memory and processors (controls) to store large complicated
programs and automated routines, and to rapidly generate the signals for
complex simultaneous machining motions.  When properly programmed, CNC
machines can perform complex milling operations more efficiently than
skilled machinists utilizing manual methods.

CAM software expedites the manufacturing processes, particularly the complex
milling and machining operations associated with mold, tool, die and
piece-part manufacturing because CAM systems are used to generate these
complex CNC programs efficiently and accurately.  CAM systems can generate
CNC programs in a manner which provides graphics aids to the operator for
development of complex geometry and cutting tool motion instructions.  These
CAM systems also allow the operator to view a simulation of the program, of
the cutting tool and of the machine-tool motion as the program steps through
its execution sequence.  The CNC programs are usually lengthy and a magnetic
medium or a directly wired or networked transmission is typically used to
send the programs from the programming source to the CNC control.

CAM software, like CAE, receives part models from CAD systems. 
Alternatively, the part can be "traced" with physical devices that convert
part shape to digital data (digitize), with optical recognition systems that
also digitize models, and with highly precise laser digitizing devices. 
When a part model is received by a CAM system, three possibilities exist. 
If the part is to be machined, the CAM software can generate NC instructions
to drive a machine tool to manufacture the part.  If the part is to be
created through a molding, stamping, casting or forging process, the CAD
model must be used to develop the mold or die surfaces to be machined.  This
requires a CAM system with surface modeling capabilities since creating
machinable geometry for a mold or die is also required; a mold or die is not
simply the 3-D reverse of the part.  If the part is not manufacturable as
designed, the model must be modified for machining within the CAM system,
or it must be returned to the CAD system for modification and, perhaps
analysis after modification.

Iterations among CAD, CAM, and CAE software applications consume product
development time.  In addition, tracking revisions and modifications can
become problematic.  Associating individual geometric or material changes
of individual components to each other and to the assemblies that comprise
finished products can be difficult, can create problems or confusion, and
is always time consuming.  To alleviate this problem, software vendors began
development of PDM software, the demand for which is now gaining momentum. 
 PDM software works best where all the software applications that are
creating elements it catalogs, associates and tracks are using the same
underlying software base or architecture.  It is for this reason that large
CAD/CAM/CAE companies are also becoming the primary suppliers of PDM
software.

Integrated systems provide the same underlying architecture for the CAD, CAM
and CAE functions, facilitating interchange of data and data models among
the various components.  Stand-alone systems, whether CAD, CAM, or CAE must
rely on direct data translators or on industry standard data formats to
exchange data. Today, both types of systems exist in all three software
areas.  CAMAX has stand-alone CAM software, which relies on direct
translators and the IGES, VDA and DXF data exchange formats.

Recent Developments

Purchase of ManufacturingExpert.  On August 9, 1994, CAMAX purchased the
assets for the ManufacturingExpert, a CAM software product, from Autodesk,
Inc.  The purchase price for ManufacturingExpert was $1,568,000.  CAMAX paid
$300,000 at the closing, assumed $68,000 in liabilities and entered into a
noninterest-bearing promissory note for $1,200,000 in favor of Autodesk,
Inc. payable in three equal annual installments of $400,000.  The purchase
agreement between CAMAX and Autodesk, Inc. contains a provision whereby
payment of certain amounts owing to Autodesk, Inc. will accelerate upon a
change in control of CAMAX and become immediately due and owing to Autodesk,
Inc.

In connection with CAMAX's acquisition of the ManufacturingExpert assets
from Autodesk, Inc., Autodesk, Inc. granted a license back to CAMAX for the
use of certain of the source code of the ManufacturingExpert software. 
Under the terms of the license agreement, Autodesk, Inc. may, at its option,
terminate the license agreement upon a change of control of CAMAX.

Merger of Point Control.  In September 1994, CAMAX consummated a merger with
Point Control Co., an Oregon corporation ("Point Control"), pursuant to
which each issued and outstanding share of Point Control common stock was
converted into 17.75 shares of CAMAX Common Stock and Point Control became
a wholly-owned subsidiary of CAMAX.  Founded in 1984, Point Control
developed and marketed vertical application software, including its SmartCAM
products, for the general CAM segment of the CAD/CAM industry.

Obsolescence of ManufacturingExpert.  While enhancing ManufacturingExpert
for the product's first maintenance release under the CAMAX name, CAMAX
determined that it could best deliver and continue to deliver advanced NC
functionality through its Camand product, and that it would be more
beneficial to its customers, and more efficient and cost effective for
CAMAX, to develop ManufacturingExpert-like functionality for Camand and to
deliver future releases of Camand to ManufacturingExpert users than to
continue development of ManufacturingExpert.  In the third quarter of 1995,
CAMAX announced a migration program for its ManufacturingExpert users, with
a goal of completing the migration in 1996.  By 1995 year end, CAMAX had
delivered the Camand product to over one half of its entire
ManufacturingExpert customer base.

No further enhancements or releases are planned for the ManufacturingExpert
product.

CAMAX Products

CAMAX software now consists of two product families, Camand and SmartCAM. 
 Differentiation between the two families is best made through complexity
of part geometries, manufacturing processes, and machine-tool motion
required to produce the parts.  CAMAX software products address the needs
of all manufacturers using NC and CNC machine tools and rapid-prototyping
equipment for producing prototypes, parts, tooling, molds and dies.  Key
industries are automotive; tool, die and mold makers; aerospace; general and
industrial machinery; consumer products; suppliers to all these industries;
and general job shops.

Camand, with surface modeling and machining capabilities geared for
geometrically complex parts and for machining with complex machine-tool
motion, is especially suited to mold and die work in all industries,
aerospace component manufacturing, and specialized CNC machining
applications requiring 4 and 5 axes in simultaneous motion.  Typical
applications for Camand's ability to model and machine geometrically complex
parts are automotive stamping dies and plastic injection molds in all
industries.  Applications requiring complex machine tool motion are
exemplified by the machining of turbine blades and aircraft wing spars.

SmartCAM is geared for a wide variety of procedurally complex CNC work. 
Automated and interactive features of the system were developed with a focus
on simplifying, modeling and optimizing the NC machining process for various
types of machine tools.  SmartCAM software allows users to generate NC
programs with multiple NC operations and efficient sequencing of operations
for optimal machine-tool motion.  These capabilities make SmartCAM specially
suited for production machining applications where time savings are
multiplied over dozens, hundreds or thousands of parts.  It is also an ideal
application where production CNC work and 3-axis surface machining are both
required from a single software product.  Because SmartCAM applications have
a broad reach across multiple industries, typical applications are best
categorized by individual SmartCAM application, but can be described,
overall, as general piece-part manufacturing, which comprises nearly 70% of
the market using CNC machine tools.
 
Camand.  Camand comprises several modules which are combined to deliver
integrated packages for specific sectors of the manufacturing markets. 
Camand software makes use of high-resolution graphics with an interactive
user interface supported by a mouse, buttons and dials for dynamic pan,
zoom, rotation and manipulation of geometry.  The recent version 10.0
release of Camand also supports an increasingly popular, ergonomically
engineered, user interface device called the Spaceball, manufactured by the
Spacetec IMC Corporation, to offer an alternative to the combination of
mouse, buttons and dials.

General functionality delivered by the multiple modules of Camand includes
NC programming with interactive editing capabilities, wireframe and surface
modeling, dynamic visualization, NC verification, machine-tool simulation,
and translation from and to nearly all CAD or CAD/CAM systems.  In addition
to selecting standard packages for seat or network licensing, customers may
also select additional  modules, assigning each for seat or network
licensing.  Camand is supported on UNIX workstations and Intel-based PCS
running the Windows NT operating system.

Five separate packages, created by integrating different modules, are
marketed under the general name of Camand.  The packages are Camand Modeler,
Camand NC, Camand Partmaker, Camand Machinist and Camand Multax.  All five
packages, including the Camand Modeler, are geared for users whose ultimate
goal is a manufactured part.  Each software package includes a graphic user
interface, data manager, basic modeling functions, documentation, data
translation and output device drivers.  Also included in each package is an 
easy-to-use programming language which enables users to customize features
for added efficiency or corporate standards, to automate parameter-driven,
associative programming, and to automate repetitive modeling or NC
programming functions.  Software modules not included in packaged systems
are available as purchasable options.

Purchasable options are Camand Lathe, Camand Wire EDM, Camand NCV (a visual
machining verification application), bidirectional IGES and VDA translators,
and Viewmax, software used for high-resolution shading of part models to
check for surface continuity and smoothness.

With the exception of the Camand Modeler, all Camand software packages
include the NC programming functionality and universal postprocessor
necessary to meet the needs of the intended market.  The various software
packages support multiple NC/CNC machine tool types and configurations from
the simplest (Camand Partmaker) to the most complex (CAMAX Multax),
including machining centers, turning centers, mills, lathes, lasers and wire
EDM.  Standard NC program output is APT-CL which is used by the Camand
postprocessor to generate machine specific code to drive NC and CNC machine
tools with up to a 5-axis simultaneous motion. 

The Camand applications, by nature, need to operate within various CAD
environments, and must therefore accept data from multiple sources.  CAMAX
has invested much development effort to accommodate data translation, and
has differentiated the Camand product from competitive offerings with
continuous development and support of industry standard data translators. 
Camand receives CAD data in the IGES, VDA and DXF formats and exports model
data in the IGES and VDA formats.  In addition, Camand exports data for
rapid prototyping systems in a format common to many of these, the STL file
format.

SmartCAM.  SmartCAM applications are based on technology that incorporates
attributes of the target machine tool into the computer model as the user
builds a toolpath.  This allows users to predict results and to optimize the
toolpath for time and material savings before the actual CNC machine code
is generated.  The technological base of SmartCAM also allows users to
customize and automate SmartCAM applications to meet individual
requirements.

The SmartCAM product family, originally developed for the PC platform with
subsequent migration to Unix workstations, comprises seven separate and
distinct applications, each targeting a specific manufacturing process or
machine-tool type, plus an additional six optional modules.  In addition,
certain of the applications are packaged together and offered at bundled
pricing.  The multiple applications within the SmartCAM family provide CNC
programming capabilities across the broadest range of CNC machinery, and one
of the deepest ranges within individual machine-tool categories.

The SmartCAM Production Milling application accommodates production
environments using 3-axis CNC milling machines for producing piece parts
with 2 1/2-axis machine tool motion, typical of high-volume machining
operations in large manufacturing companies and small job shops.  Parts
machined with SmartCAM Production Milling are the most common, typically
incorporating multiple drilling, tapping, threading, pocketing and profiling
operations.   Support for a rotary axis enables rotating parts on a fixture
to machine the part from different directions, or to employ tombstone
machining, the mounting of multiple stock pieces on fixtures for automatic,
sequential rotation into machining position. 

SmartCAM Advanced 3-D Machining incorporates all the capabilities of
Production Milling and adds a third axis of simultaneous motion, and a
fourth axis of positioning motion, enabling users to machine the simpler of
3-dimensional surfaces in addition to all typical 2 1/2-axis machining
operations.  The combination of 2 1/2-axis milling and surface machining
enables Advanced 3-D Machining to provide all the capabilities necessary to
cut most machined parts.
 
SmartCAM FreeForm Machining includes all the functionality of Advanced 3-D
Machining and adds the ability to machine multiple, complex surfaces.  It
is considered to be one of the fastest applications in the industry in
generating CNC programs across geometry incorporating multiple surfaces. 
Because this application has high machining functionality and accepts
ACIS-based solid models and complex IGES surface models for machining, it
is gaining acceptance as a partnership application for several ACIS-based
CAD suppliers.

SmartCAM Production Turning provides the CNC programming required for
piece-part production with 2-axis CNC lathes and supporting linear, contour
and groove roughing operations.  Parts created with 2-axis lathes typically
involve a single profile revolving about the part axis, often having threads
machined on the lathe.  The simplest of these parts can be represented by
cylindrical shapes.  

SmartCAM Advanced Turning elevates the CNC programming capabilities of
Production Turning for application to complex 4-axis lathes and 6-axis
millturn centers, which are specialized CNC machine tools that combine
turning and machining operations on a single machine.   SmartCAM Advanced
Turning enables programming both types of machines to create complex parts
with reduced fixturing, reduced scrap, and increased quality.  In addition
to supporting  these complex machines, Advanced Turning provides all the
capabilities of Production Turning.

SmartCAM Advanced Wire EDM supports the growing category of traveling wire
electric discharge machines, which employ an electrically charged wire
moving through metal to generate the piece-part.  SmartCAM Advanced Wire EDM
provides automated functions that enable untended machine operation,
especially important for this machine type since the EDM process is slow,
relative to other machining operations.

SmartCAM Advanced Fabrication primarily supports the sheet-metal fabrication
industry, although its functions support CNC equipment used in other
industries.  Its CNC programming functions drive sheet-metal punches,
burners, punch/plasma combinations, and laser- and waterjet-cutting
equipment.  Advanced Fabrication supports 2-D and 3-D fabrication
requirements, provides canned cycle (automatic machine) support and part
nesting capabilities.  It does automatic folding and unfolding of flat
patterns and optimizes the CNC programs.  These functions, combined with its
ability to create transition pieces with minimal user input, allows Advanced
Fabrication to also work well in sheet metal fabrication within the HVAC
industry.

The SmartCAM applications are enhanced to operate within various CAD
environments with additional modules that facilitate data translation.   The
AutoCAD SmartCAM Connection allows designers to add machining processes to
AutoCAD mechanical design models to generate CNC programs in SmartCAM
without going through a DXF file transfer.  The SmartCAM CAM Connection
bundle includes IGES and DXF translators.  An additional module, Tape to
Shape, allows converting CNC toolpath data into SmartCAM geometry for
modification or reverse engineering.  In addition, a SmartCAM Localization
Kit is marketed to resellers and system integrators to develop local
language interfaces for SmartCAM applications.

Product Enhancements.  Regular releases of software contribute to CAMAX's
position in the industry.  In 1994, CAMAX began a time-based release
schedule to update all of its products on a regular twice-a-year release
schedule.  As a result, CAMAX is able to provide meaningful enhancements to
its customers in new releases of each product every six months.

CAMAX Market and Customers

The discrete manufacturing industry has undergone and continues to undergo
dramatic changes in process and technology.  Market forces and international
competition, notably from Japan and other Asian regions, are causing
companies to move away from large lot, long production runs that carry
economies of scale, to shorter, more flexible production runs that can
respond to changing market developments.  At the same time, machine tool and
control technologies are evolving to make one-off and rapid response
manufacturing more cost effective.  Manufacturing engineers and NC
programmers are faced with the challenges of increasing quality, controlling
production costs and shortening time to market.

Significant shifts are also occurring in the geographic distribution of the
CAD/CAM market, as the growth in Europe and the Asia/Pacific markets out-paces
the North American market.  In the near term, it is anticipated that
the European market will overtake the North American market and become the
largest single CAD/CAM market.  Longer term, China is believed to have the
largest growth potential for CNC machine tool consumption and, therefore,
provide a large market for NC programming software.  With these geographic
changes, process changes are occurring as well.  While product design,
manufacturing and engineering, and NC programming have in the past been
considered as discrete tasks, companies are now moving towards concurrent
engineering believing that significant benefits can be realized by improving
communications and data sharing among these areas and treating them as
concurrent processes.  Thus the traditional sequential nature of the
design-to-manufacture process is being replaced with concurrent, iterative
processes and systems.

Historically, CAMAX's software and systems have been targeted generally at
the mechanical manufacturing segment of the CAD/CAM market.  This market
segment is composed of two types of customers.  One customer group includes
captive departments within vertically integrated firms which manufacture a
product from engineering specifications and drawings.  The other customer
group consists of independent contractors which perform all or part of these
manufacturing engineering services, such as mold design and manufacture or
piece-part production, for their customers.  Both groups require extensive
CNC programming features such as those offered by CAMAX software.  Each
group can be further subdivided into the type of machining services they
require.  Some need one-off type of manufacturing, such as prototype or
model making.  Similarly, those requiring mold or die machining may require
one-off production or low quantity, high complexity machining.  The largest
category, industry wide, are those who require production piece-part
machining.  Original manufacturers or contractors in this category can
require several small lots of parts machined each year, or may require
frequent lots of thousands of identical parts.

Originally, CAMAX's target market fell in the one-off category, and CAMAX
marketed its Camand software to captive model and prototype shops and to
mold-making and die-making operations of all sizes.  Overall, the
combination of these operations approximates 30% of the entire CNC machining
industry.  Further, when these shops are not captive internal operations,
they typically fall into the third tier supplier category.  To install
stand-alone CAM software in the internal captive shops of large companies,
longer sales cycles are often required because vendors must overcome
corporate policies dictating specific CAD/CAM software for all purposes and
prove that mandated software is incapable of performing necessary functions
before other software is approved.  On the other hand, smaller shops,
typically suppliers to several large companies, require NC programming
capabilities within a system that accepts data from multiple sources. 
These, then, became the bulk of the CAMAX market.

The CAM assets of Autodesk, including the ManufacturingExpert product, were
acquired to address the same mold- and die-making market, but with a product
that operated on a PC platform.  Even with two platforms, CAMAX software was
still targeted for approximately 30% of the market.

Merging with Point Control Co. provided solutions on the same platforms, but
with software to address the needs of the general machining market, which
approximates 70%.  Point Control had also developed an application within
the SmartCAM product line to provide some of the capabilities of
ManufacturingExpert, falling short in some areas and exceeding it in others. 
With the combination of products, CAMAX is now able to address nearly the
entire CNC manufacturing market, although sales to the large companies still
require longer sales cycles due to requirements for company-mandated CAD/CAM
systems or requirements for native-file integration of all applications. 
 
With broad CAM product offerings, CAMAX now has an installed base of
approximately 25,000 seats of software installed at 12,000 customer sites. 
Representative customers are AT&T, Advanced Cardiovascular Systems, American
Mold, ASICS, Ben Hogan, B & B Tool and Mould, Black & Decker, CAE
Electronics, California Amplifier, Converse, Crucam, Custom Mold, Dowty
Aerospace, Edelbrock, FGL Precision Works, Fokker, General Motors, H.S. Die,
Hamilton Standard, Hendrick Motosports, Hewlett-Packard, Hitachi, Honda
Engineering, Industrial Molds, Johnson Controls, JVC, Motorola, Nabisco,
Nissan, Ogihara Seiki, Phillips Plastics, Pioneer, Pratt & Whitney, Red Dog
Industries, Reynolds Mason, Ricoh, SAAB, Satellite Models, Service Tool &
Die, Shimano, Shutt Medical, Starline Manufacturing, Tell Tool, Toyota and
Westinghouse.

CAMAX has historically made sales to existing customers for expansion and
upgrades of the capabilities of their systems.  Many of CAMAX's customers
have ordered additional software or systems from CAMAX subsequent to initial
installations.  CAMAX's expectation is that this pattern will continue.

Competition

The CAM market is highly competitive and is characterized by continual
change and improvement in technology.  CAMAX's existing and potential
competitors can be divided into two major categories.  Large CAD/CAM/CAE
suppliers, with substantially greater financial, marketing and technical
resources than CAMAX, present the greatest competition.  While most of their
applications are not for CAM, and their focus is not CAM, demand for
integrated product sets allow them an advantage in marketing to many
companies. Companies in this category are Computervision, Dassault Systemes,
EDS Unigraphics, Intergraph and Matra Datavision.

A second major category of competitors comprises CAM-focused companies. 
Although CAMAX is the largest of these, as a group of over one hundred
companies, these competitors often have an advantage in either direct local
representation, low price or sub-niche specialization.  Representatives of
this group are CNC Software, DP Technology, Delcam and Gibbs Systems. Within
this category is a growing sub-category which is focusing on a sub-niche of
the CAM market with specialized machining applications that can operate with
data from nearly all CAD, CAD/CAM or CAM software systems, offering fast NC
code generation for the more popular 3-axis styles of machining surfaces. 
Companies in this group are limited, but their growing success is gaining
attention in the industry.  The WorkNC product from Sescoi, Hypermill from
Open Mind Software, and PowerMill from Delcam fall into this group.
  
CAMAX believes that the principal factors enabling its ability to compete
in a CAM market with many suppliers are the breadth and depth of product
offerings, the range of customer support and services, the ability of
products to interface with a variety of widely used hardware, demonstrable
productivity gains from using the product, the size of CAMAX's user base and
alliances with major hardware and software vendors.

CAMAX expects that its business strategy and focus on developing
knowledge-based products with advanced CNC programming features will
continue to limit the number of CAD/CAM companies against which it will
directly compete with its software products.  However, with the growing
number of companies that have developed an interest in satisfying the
machining market with CAM software, there is no assurance that existing CAM
or CAD/CAM or other companies have not or will not begin marketing products
focused on the market selected by CAMAX or that further consolidation in the
marketplace will not produce a supplier capable of marketing products in
CAMAX's market.  Should such developments occur, the degree of competition
within this CAD/CAM niche will intensify.

CAMAX's broad range of applications, with open architecture, provides the
advantages of flexibility and transportability.  Flexibility allows
customers to purchase only that software necessary to drive their specific
type or configuration of machine tool, thereby reducing their entry cost. 
This is a key advantage of the SmartCAM application set.   Transportability
enables customers to purchase hardware configurations which match the
performance and price point they require for running their applications. 
This is an advantage of both Camand and SmartCAM.  The complex modeling,
multi-axis CNC programming and machine-tool simulation tasks can be
performed on high performance systems and tasks such as 2-axis lathe work
and 3-axis milling can be performed on lower priced systems.  Within product
families, CAMAX's software can operate in a networked manner utilizing a
common data base with users operating the systems with common commands and
procedures. Network licensing schemes for Camand allow users to license
specific packages, thereby gaining the benefits of reduced overall costs.

SmartCAM also gives CAMAX an advantage because it provides products ranging
from $3,500 to $13,000 per license.  Camand applications, which are
generally considered "high-end," range from $9,500 to $32,000.  Combined
with CAMAX's attractive trade-up incentives, CAMAX can offer entry-level
packages to customers with limited budgets or those only beginning to use
CNC machines, and keep them moving upward within and across applications. 


Marketing and Sales

CAMAX products are marketed and supported in over 50 countries through a
value added reseller (VAR) channel, which is managed and supported by a
sales force with the assistance of CAMAX application engineers.  Application
engineers demonstrate CAMAX applications to both direct and reseller
prospects, provide advanced training to reseller application and sales
engineers, and act as internal consultants to employees who are dedicated
to reseller and customer training, consulting and support.  Currently CAMAX
has 12 sales people and 13 application engineers.  In addition to sales and
support people located across the United States, CAMAX  also has sales
personnel in The Netherlands, France, and Germany. 

CAMAX uses a standard VAR agreement with its resellers, who represent CAMAX
products in 53 different countries, including Canada, Mexico, U.S.A., Puerto
Rico, West Indies, Costa Rica, Argentina, Brazil, Chile, Colombia, Peru,
Venezuela, Austria, Belarus, Belgium, Croatia, Czech Republic, Denmark,
England, Finland, France, Germany, Greece, Hungary, Ireland, Italy,
Luxembourg, Netherlands, Norway, Poland, Portugal, Russia, Scotland, Spain,
Sweden, Switzerland, Ukraine, Yugoslavia, China (PRC),Hong Kong, Indonesia,
Japan, South Korea, Malaysia, Phillipines, Thailand, Taiwan (ROC),
Singapore, Australia, New Zealand, India, Turkey, and South Africa.

CAMAX sells on a direct basis only to "corporate accounts," which are those
customers who require support agreements directly from the software
manufacturer as a matter of corporate policy.

CAMAX promotes its products through direct advertising, referrals, an
electronic bulletin board service ("BBS"), a Web site, industry trade shows,
and events held and promoted by strategic partner CAD vendors.  Until late
in 1995, direct advertising was restricted to the United States.  Late in
1995, plans for direct advertising were developed to support resellers in
strategic growth areas.  To date, advertising outside of the United States
has been limited, but plans include extending advertising to other areas.

CAMAX product promotion through industry trade shows has increased in recent
years.  CAMAX participates in all major manufacturing-focused trade shows
in the United States, and supports its resellers with participation in
regional shows, both nationally and internationally.  Aside from its direct
exhibits and joint exhibits with resellers, CAMAX usually participates in
several CAD-vendor exhibits at these and other trade shows, as CAMAX
products are seen as complementary and often enabling technologies.

Through trade shows and joint-marketing events, promotion through strategic
CAD partnerships has also been increasing.  CAMAX has participated in
several vendor-specific events with various companies, and has participated
in Autodesk, Hewlett-Packard and Silicon Graphics events worldwide, and
continues to do so.  

Customer Support Services

In addition to sales of its software licenses, CAMAX offers a wide range of
services to ensure that its products deliver value for each customer's
investment.  CAMAX offers tutorials to help users learn the system
independently.  A training group holds formal training classes for customers
and resellers at CAMAX's Minneapolis facility.  The training group also
certifies resellers and educational institutions for authorized training
programs, and assists them in developing training curricula.  Through their
effort, product training is also held at Authorized Training Centers, which
include VAR facilities and public education institutions around the world.

CAMAX maintains a Customer Support group in both the Minneapolis and Eugene
facilities.  These employees are dedicated to providing telephone hot-line,
fax-back support and consulting services for customers and resellers. 
Taking advantage of the time difference between the two facilities, they
provide support from 7:00 A.M. to 7:00 P.M. Central Time.

CAMAX and its representatives also offer on-site support and consulting
services for customers needing access to the higher capabilities of the
software and those needing assistance with their most difficult or unusual
jobs. 

The Application Engineering group, whose primary responsibility is assisting
the direct sales force in support of the VAR channel, consists of skilled
system operators who also act as a test site and laboratory for CAMAX
technology.  Through their direct use of the software and information
received from reseller engineers and customers, they provide data on
application requirements, performance and productivity.  These application
engineers also provide additional post-sale support and consulting services
as a supplement to the Customer Support group.

Finally, CAMAX offers complete software enhancement services through
Software Maintenance Agreements.  Today, approximately 70% of Camand and 35%
of SmartCAM users subscribe to these services and receive all software
updates. 

Sources of Supply

CAMAX develops nearly all of the fundamental application software and system
interface software used in its systems and employs 39 full-time development
personnel.  CAMAX licenses certain third-party software utilities, which its
development group integrates with CAMAX applications.  For example, CAMAX
has contracted with International Technegroup, Inc., a software developer
specializing in data translation and data integration, to develop and
support translators for Camand and SmartCAM.  In addition, to increase its
hardware platform independence, CAMAX has contracted with Ithaca Software,
an Autodesk subsidiary, to supply system software for graphics technology.

As CAMAX changed its sales strategy from one of turnkey provider, supplying
third-party computers and peripherals with its software, to one of
software-only provider, CAMAX has no direct reliance on hardware
manufacturers.  CAMAX delivers its software to VARs, who then provide the
hardware and peripherals with CAMAX software, to supply a turnkey system to
customers.  Direct customers receive software from CAMAX and obtain their
hardware directly from vendors, from CAMAX resellers or from other parties.

The transportable nature of CAMAX's software reduces reliance upon any
particular brand of hardware.  CAMAX currently supports Intel-based PCS
running the DOS, Windows, Windows NT and Windows 95 operating systems, and
UNIX workstations from Silicon Graphics Inc., Hewlett-Packard and Sun
Microsystems.  CAMAX resellers obtain computer hardware and peripherals
either directly from the vendors or through resellers of the hardware
vendors.  

Copyrights, Trade Secrets and Trademarks

CAMAX's SmartCAM software is protected by registered copyrights.  CAMAX also
relies upon the law of trade secrets and the confidentiality provisions of
its contracts with customers to protect its proprietary SmartCAM software.

CAMAX's Camand software is not protected by patents or registered
copyrights, and CAMAX instead relies upon the law of copyright and trade
secrets, and the confidentiality provisions of its contracts with customers
to protect its proprietary software.  Management believes that the
protection of its software by patents or copyrights is less important than
the knowledge, experience and creativity of CAMAX's product development and
marketing staff in an industry characterized by rapid technological change. 
There can be no assurance that competitors could not successfully copy or
duplicate CAMAX's proprietary software.

Camand and SmartCAM are registered trademarks and ManufacturingExpert is a

Employees

As of January 31, 1996, CAMAX had 156 employees, including 30 in sales and
marketing positions, 39 in engineering and product development, 56 in
technical training and support and 31 in financial and administrative roles. 
None of CAMAX's employees is represented by a labor union and CAMAX has not
experienced a work stoppage or labor relations problems and believes its
relations with its employees are good.

Property

CAMAX's principal offices are located at 7851 Metro Parkway, Minneapolis,
Minnesota 55425, in an 26,238 square foot office facility under a lease
expiring in 2000.  CAMAX also leases office facilities in Eugene, Oregon
with an aggregate of 29,200 square feet. In addition, CAMAX leases an
engineering and product development office in High Wycombe, United Kingdom.

Employment Agreement

In connection with the 1994 merger of Point Control and CAMAX, on September

Agreement") with Mr. Bruce Winegarden.  The term of the Employment Agreement
is for two years.  According to the terms of the Employment Agreement, Mr.

reasonable employment duties as the Board of Directors of CAMAX shall assign
to him from time to time.  In consideration of his efforts on behalf of
CAMAX, Mr. Winegarden is to receive a base salary of $150,000 for each year
during the term of the Employment Agreement.  Mr. Winegarden is also
entitled to participate in any incentive compensation plans which may be
established by the Board of Directors of CAMAX during the term of the
Employment Agreement.  If CAMAX  terminates the Employment Agreement because
Mr. Winegarden has become disabled (as defined in the Employment Agreement)
or has committed any criminal act or act of fraud or dishonesty in any
material respect related to or connected with his employment by CAMAX, Mr.
Winegarden is entitled to receive a lump-sum severance payment of $150,000. 
If Mr. Winegarden terminates his own employment with CAMAX prior to
September 2, 1996, he is entitled to receive a lump-sum severance payment
of $75,000 and an additional $75,000 in consideration of his continuing
agreement not to compete with CAMAX for a period of one year after such
termination.  If Mr. Winegarden terminates his own employment with CAMAX
upon expiration of the Employment Agreement, he is entitled to receive
$75,000 in consideration of his continuing agreement not to compete with
CAMAX for a period of one year after such termination.   The Employment
Agreement also requires that any intellectual property conceived of or
created by Mr. Winegarden shall remain the property of CAMAX and that Mr.
Winegarden shall not divulge to anyone or use in any way any confidential
or secret knowledge or information of CAMAX which Mr. Winegarden acquired
or became acquainted with prior to the termination of the Employment
Agreement for whatever reason.  The Employment Agreement will survive the
Merger and become the binding obligation of both the Acquisition Corp. and
Mr. Winegarden in accordance with its terms following the consummation of
the Merger.

Stock Plans

In the following context, all references to fair market value are as
determined by the Board of Directors of CAMAX.

1985 Stock Option Plan.  Pursuant to the 1985 Stock Option Plan, directors,
executive officers, and other employees of CAMAX may receive options to
purchase CAMAX Common Stock.  The 1985 Stock Option Plan was approved by the
Board of Directors in October 1985.  The 1985 Stock Option Plan provides for
the grant of incentive stock options intended to qualify for preferential
tax treatment under Section 422 of the Internal Revenue Code of 1954, as
amended.  The exercise price of all options granted under the 1985 Stock
Option Plan must equal the fair market value of the CAMAX Common Stock at
the time of grant as reasonably determined by a committee of the Board of
Directors.  In the event of a merger, consolidation, reorganization,
recapitalization, stock dividend, stock split or other change in the
corporate structure of CAMAX, appropriate adjustments in the 1985 Stock
Option Plan and outstanding options are to be made by a committee of the
Board of Directors.  The 1985 Stock Option Plan is administered by the
Compensation Committee of the Board of Directors of CAMAX and terminated in
October 1995.  Despite the termination of the 1985 Stock Option Plan, all
options issued pursuant to the 1985 Stock Option Plan shall continue for
their natural term and be exercisable in accordance with their respective
terms.

A total of 175,000 shares of CAMAX Common Stock has been reserved for
issuance under the 1985 Stock Option Plan.  As of December 31, 1995, CAMAX
had outstanding options to purchase an aggregate of 5,100 shares, at a
weighted average exercise price of $2.10 per share, pursuant to the 1985
Stock Option Plan.

1987 Stock Option Plan.  Pursuant to the 1987 Stock Option Plan, directors,
executive officers, other employees, consultants and independent contractors
of CAMAX may receive options to purchase CAMAX Common Stock.  The 1987 Stock
Option Plan was approved by the Board of Directors in November 1987.  The
1987 Stock Option Plan provides for the grant of non-qualified stock options
that do not qualify for preferential tax treatment under Section 422 of the
Code.  The exercise price of all options granted under the 1987 Stock Option
Plan must equal or exceed 50% of the fair market value of the CAMAX Common
Stock at the time of grant as reasonably determined by the Board of
Directors or a committee thereof.  In the event of a merger, consolidation,
reorganization, recapitalization, stock dividend, stock split or other
change in the corporate structure of CAMAX, appropriate adjustments in the
1987 Stock Option Plan and outstanding options are to be made by the Board
of Directors or a committee thereof.  The 1987 Stock Option Plan is
administered by the Compensation Committee of the Board of Directors of
CAMAX and will expire in November 1997, unless terminated earlier by the
Board of Directors of CAMAX as provided in the 1987 Stock Option Plan.

A total of 2,400,000 shares of CAMAX Common Stock has been reserved for
issuance under the 1987 Stock Option Plan.  As of December 31, 1995, CAMAX
had outstanding options to purchase an aggregate of 603,250 shares, at a
weighted average exercise price of $.49 per share, pursuant to the 1987
Stock Option Plan.

Point Control Stock Option Plan.  Pursuant to the Point Control Stock Option
Plan, employees of Point Control received options to purchase Point Control
Common Stock prior to the consummation of the 1994 merger between Point
Control and CAMAX.  In connection with the 1994 merger of Point Control and
CAMAX, the previously issued options to purchase shares of Point Control
Common Stock became the right to purchase shares of CAMAX Common Stock on
the same terms as though all such options had been exercised immediately
prior to the consummation of the merger between Point Control and CAMAX. No
further options were granted to employees of Point Control following the
1994 merger between Point Control and CAMAX.  The Point Control Stock Option
Plan was approved by the Point Control Board of Directors in April 1987 and
approved by Point Control's shareholders in April 1987.  The Point Control
Stock Option Plan provides for the grant of both incentive stock options
intended to qualify for preferential tax treatment under Section 422 of the
Code, and non-qualified stock options that do not qualify for such
treatment.  The exercise price of all options granted under the Point
Control Stock Option Plan must equal or exceed the fair market value of the
Point Control Common Stock at the time of grant as reasonably determined by
the Board of Directors or a committee thereof.  The Point Control Stock
Option Plan also provides for grants of stock appreciation rights. In the
event of a merger, consolidation, reorganization, recapitalization, stock
dividend, stock split or other change in the corporate structure of CAMAX,
appropriate adjustments in the 1987 Stock Option Plan and outstanding
options are to be made by the Board of Directors or a committee thereof. 
The Point Control Stock Option Plan is administered by the Compensation
Committee of the Board of Directors of CAMAX and will expire in April 1997,
unless terminated earlier by the Board of Directors of CAMAX as provided in
the Point Control Stock Option Plan.

A total of 100,000 shares of Point Control Common Stock was originally
reserved for issuance under the Point Control Stock Option Plan.  Following
the 1994 merger between Point Control and CAMAX and giving effect to the
exchange ratio in such merger, a total of 1,775,000 shares of CAMAX Common
Stock has been reserved for issuance under the Point Control Stock Option
Plan.  As of December 31, 1995, CAMAX had outstanding options to purchase
an aggregate of 208,888 shares, at a weighted average exercise price of $.47
per share, pursuant to the Point Control Stock Option Plan.

1995 Stock Option Plan.  Pursuant to the 1995 Stock Option Plan, directors,
executive officers, other employees, consultants and independent contractors
of CAMAX may receive options to purchase CAMAX Common Stock.  The 1995 Stock
Option Plan was approved by the Board of Directors in April 1995 and
approved by CAMAX's shareholders in June 1995.  The 1995 Stock Option Plan
provides for the grant of both incentive stock options intended to qualify
for preferential tax treatment under Section 422 of the Internal Revenue
Code of 1986, as amended, and non-qualified stock options that do not
qualify for such treatment.  The exercise price of all options granted under
the 1995 Stock Option Plan must equal or exceed the fair market value of the
CAMAX Common Stock at the time of grant as reasonably determined by the
Compensation Committee.  The 1995 Stock Option Plan also provides for grants
of stock appreciation rights, restricted stock awards and performance
awards.  Only employees are eligible for the grant of incentive stock
options.   In the event of a merger in which CAMAX is not the surviving
corporation, a transfer of all of CAMAX's stock, a sale of substantially all
of CAMAX's assets or a dissolution or liquidation of CAMAX, all outstanding
options will become exercisable in full at least ten days prior to such
event on such conditions as the Board shall determine, unless the successor
corporation assumes the outstanding options or substitutes substantially
equivalent options.  The 1995 Stock Option Plan is administered by the
Compensation Committee and will expire in May 2005, unless the Board of
Directors terminates the 1995 Stock Option Plan earlier as provided in the
1995 Stock Option Plan.

All stock options previously granted under CAMAX's 1985 Stock Option Plan,
the 1987 Stock Option Plan and the Point Control Stock Option Plan will
remain outstanding in accordance with the terms thereof following the
effectiveness of the 1995 Stock Option Plan.  However, no additional stock
options will be permitted to be granted under CAMAX's 1985 Stock Option
Plan, the 1987 Stock Option Plan or the Point Control Stock Option Plan.

A total of 3,000,000 shares of CAMAX Common Stock has been reserved for
issuance under the 1995 Stock Option Plan.  As of December 31, 1995, CAMAX
had outstanding options to purchase an aggregate of 2,266,500 shares, at a
weighted average exercise price of $.71 per share, pursuant to the 1995
Stock Option Plan.

Directors' Plan.  The 1995 Directors' Stock Option Plan (the "Directors'
Plan") provides for an automatic grant of nonqualified stock options to
purchase 25,000 shares of CAMAX Common Stock to non-employee directors of
CAMAX on the date such individuals become directors of CAMAX, and an option
to purchase 5,000 shares of CAMAX Common Stock on each subsequent annual
shareholder meeting date, subject to certain limitations.  Options granted
on the date an individual becomes a director of CAMAX shall vest and thereby
become exercisable as to one-third of such shares on the date of such grant
and one-third at each of the first and second twelve month anniversary dates
of such grant if the holder remains a director on such dates.  Options
granted on the date of each annual meeting of shareholders become
exercisable one year subsequent to the date of grant, provided, however,
that such option shall only be granted to eligible directors who have served
since the date of the last annual meeting of shareholders and will continue
to serve after the date of grant of such option.  In the event of a merger
in which CAMAX is not the surviving corporation, a transfer of all of
CAMAX's stock, a sale of substantially all of CAMAX's assets or a
dissolution or liquidation of CAMAX, all outstanding options will become
exercisable in full at least ten days prior to such event on such conditions
as the Board shall determine, unless the successor corporation assumes the
outstanding options or substitutes substantially equivalent options.  CAMAX
has reserved 400,000 shares of CAMAX Common Stock for issuance under the
Directors' Plan.  The option price for directors is equal to the fair market
value of the CAMAX Common Stock as of the date of grant.

Pursuant to the Directors' Plan, Mr. Blakely, Mr. Elftmann, Mr. Glarner, Mr.
Hadley and Mr. Lipkin each received options to purchase 10,000 shares of
CAMAX Common Stock, which options are exercisable at $.70 per share, and Mr.
Morley and Mr. Carlson each received options to purchase 25,000 shares of
CAMAX Common Stock, one-third of which vested at the date of grant and are
exercisable at $.70 per share, and the remainder of which options shall vest
and become exercisable one-third at each of the first and second twelve
month anniversary dates of such grant.  No other options have been granted
under the Directors' Plan.

Notes To The Unaudited Proforma Combined Financial Statements

(in thousands, except per share data)

(1)  Introduction

On January 16, 1996, SDRC entered into a definitive agreement to acquire
CAMAX  and its Subsidiaries.  CAMAX provides CAM software for computerized
numerical control machining operations, with products and services designed
to simplify, automate and optimize the machining process, to streamline
production and to accelerate time to market.

SDRC will issue SDRC Common Stock having a market value of $30,000 in
exchange for 100 percent ownership of CAMAX Common Stock.  The total number
of SDRC shares of common stock to be issued will be determined based on the
market price for a twenty day period preceding the fifth day prior to the
close of the transaction.

The proforma combined data (unaudited) as of and for the nine months ended
September 30, 1995 and the years ended December 31, 1994, 1993 and 1992 are
based on the historical consolidated financial statements of SDRC and CAMAX
adjusted to give effect to  the transaction as though it had occurred as of
January 1, 1992.

(2) Proforma Adjustments

The proforma adjustments to the unaudited proforma data are as follows:

a)  To record the issuance of an estimated 1,158 shares of SDRC Common Stock
with a stated value of $.0069 in exchange for all of the outstanding CAMAX
Common Stock, none of which has any par value.  The number of SDRC shares
has been estimated based on a market value of $25.9055 as calculated by the
average closing price of the SDRC stock for the twenty days ending on the
fifth trading day prior to  the public announcement of the Merger.

(b) To conform the accounting for income taxes to FAS 109 as of January 1,
1992 and to establish a 100% valuation allowance against the CAMAX deferred
tax assets since management believes it is more likely than not that the
deferred tax assets will not be realized.

(c) To reclassify the amount paid by Point Control Co. (which was acquired
by CAMAX in 1994) to its employees  who  redeemed their Point Control Co.
stock upon termination of employment. 


                     DESCRIPTION OF CAPITAL STOCK

SDRC is authorized to issue 100,000,000 shares of SDRC Common Stock, without
par value.  As of December 29, 1995, SDRC had outstanding 30,535,975 shares
of SDRC Common Stock.  Acquisition Corp.'s authorized capital stock consists
of 50 shares of common stock, without par value, of which 10 shares are
issued and outstanding.

CAMAX is authorized to issue 50,000,000 shares of CAMAX Common Stock, of
which 18,211,692 shares were issued and outstanding as of December 31, 1995. 
As of December 31, 1995, CAMAX had issued options to purchase a total of
3,290,238 shares of CAMAX Common Stock.  Of this amount, options to purchase
5,100 shares of CAMAX Common Stock had been issued pursuant to CAMAX's 1985
Stock Option Plan at a weighted average exercise price of $2.10 per share;
options to purchase 603,250 shares of CAMAX Common Stock had been issued
pursuant to CAMAX's 1985 and 1987 Stock Option Plans at a weighted average
exercise price of $.49 per share; options to purchase 208,888 shares of
CAMAX Common Stock had been issued pursuant to the Point Control 1987 Stock
Option Plan at a weighted average exercise price of $.47 per share, and
options to purchase 2,266,500 shares of CAMAX Common Stock had been issued
pursuant to CAMAX's 1995 Stock Option Plan at a weighted average exercise
price of $.70 per share.  No additional stock options will be permitted to
be granted under CAMAX's 1987 Stock Option Plan or the Point Control Stock
Option Plan.  Options under the 1995 Stock Option Plan are granted by the
Compensation Committee.  The Compensation Committee may issue options with
varying vesting schedules, but all options granted pursuant to the 1995
Stock Option Plan must be exercised within ten years from the date of grant. 
CAMAX has also issued options to purchase 100,000 shares of CAMAX Common
Stock pursuant to CAMAX's Directors' Plan at an exercise price of $.71 per
share.  CAMAX has also assumed non-qualified options issued by Point Control
to purchase 106,500 shares of CAMAX Common Stock at a weighted average
exercise price of $.42 per share.   Options granted under the CAMAX Option
Plans provide for antidilution adjustments in the event of certain mergers,
consolidations, reorganizations, recapitalizations, stock dividends, stock
splits or other changes in the corporate structure of CAMAX.  Shares of SDRC
Common stock issued to shareholders of CAMAX pursuant to the Merger
Agreement will be validly issued, fully paid and non-assessable.

                    COMPARISON OF RIGHTS OF SHAREHOLDERS

Set forth below is a description and comparison of SDRC Common Stock and
CAMAX Common Stock.  This description and analysis are brief summaries of
relevant provisions of the Articles of Incorporation of SDRC and of CAMAX
and are qualified in their entirety by reference to such documents, to the
parties' respective Codes of Regulations and Bylaws, and to the laws of the
parties' respective states of incorporation.

Voting Rights

Holders of both SDRC Common Stock and CAMAX Common Stock are entitled to one
vote per share on all matters submitted to a vote of shareholders.

The Code of Regulations of SDRC provides for the division of its Board of
Directors into two classes of approximately equal size.  Directors of the
SDRC Board of Directors are elected for two-year terms, and the terms of
office of one-half of the members of the classified Board of Directors
expire each year.  This classification of SDRC's Board may make it more
difficult for a shareholder to acquire control of SDRC and remove management
by means of a hostile takeover.  The Bylaws of CAMAX provide that each
member of the Board of Directors be elected for a one-year term at the
annual meeting of shareholders.

The holders of SDRC Common Stock have the right to vote cumulatively in the
election of directors.  Under applicable Ohio law, cumulative voting in the
election of directors of a corporation will be permitted if (i) written
notice is given by any shareholder of such corporation to the President,
Vice President or the Secretary of such corporation, not less than 48 hours
before the time fixed for holding the meeting at which directors are to be
elected, indicating that such shareholder desires that voting for the
election of directors be cumulative and (ii) announcement of the giving of
such notice is made upon the convening of the meeting by the meeting
Chairman or Secretary or by or on behalf of the shareholder giving such
notice.  In such event, each shareholder will be entitled to cumulate such
voting power as he or she possesses and to give one nominee as many votes
as the number of directors to be elected multiplied by the number of his or
her shares, or to distribute such votes on the same principle among two or
more candidates, as each shareholder sees fit.  Under Minnesota law
cumulative voting is presumed unless denied in the Articles of
Incorporation.  CAMAX's Articles of Incorporation deny cumulative voting
rights.

SDRC is only authorized to effect a merger, consolidation or sale of assets
not in the regular course of business, to dissolve, or amend its Articles
of Incorporation, pursuant to authority given by persons holding two-thirds
of its capital stock.  Minnesota law provides that an amendment to a
corporation's articles of incorporation must be by resolution approved by
the affirmative vote of a majority of the directors present at a meeting or
proposed by a shareholder or shareholders holding 3% or more of the voting
shares entitled to vote thereon.  In addition, any such amendment must be
approved by the affirmative vote of a majority of the shareholders present
at a meeting unless the articles of incorporation require a larger portion
or number.  CAMAX's Articles of Incorporation require the affirmative vote
of the majority of shares of CAMAX capital stock entitled to vote thereon. 
Minnesota law and CAMAX's Bylaws provide that the power to adopt, amend or
repeal the Bylaws shall be vested in the board of directors except that the
board shall not adopt, amend or repeal a bylaw fixing a quorum for meetings
of shareholders, prescribing procedures for removing directors or filling
vacancies in the board or fixing the number of directors or their
classifications, qualifications or terms of office, but may adopt or amend
a bylaw to increase the number of directors.  Notwithstanding the foregoing,
a shareholder or shareholders holding 3% or more of the voting shares
entitled to vote may propose a resolution to adopt, amend or repeal bylaws
adopted, amended or repealed by the board, in which event such resolution
must be approved pursuant to the procedures for amending the articles of
incorporation.

Dividends

Holders of SDRC Common Stock and CAMAX Common Stock are each entitled to
dividends as and when declared by the respective Board of Directors of each
corporation out of funds legally available for the payment of dividends. 
In the past five years, SDRC has not paid a cash dividend on any class of
SDRC capital stock.  CAMAX has never paid cash dividends on CAMAX Common
Stock.

Preemptive Rights

Under Ohio law, shareholders of a corporation are presumed to have
preemptive rights unless denied in the corporation's articles of
incorporation.  The SDRC Articles of Incorporation deny preemptive voting
rights.  Minnesota law also presumes preemptive rights unless otherwise
denied in the articles of incorporation.  CAMAX's Articles of Incorporation
deny preemptive voting rights.

Rights Upon Liquidation

Upon liquidation, dissolution or winding up, the holders of SDRC Common
Stock and CAMAX Common Stock, respectively, are entitled to share pro rata
in the distribution of all of the respective assets of such Company
available therefor.

Indemnification and Personal Liability of Directors and Officers

SDRC's Code of Regulations provides for the indemnification of each director
and officer of the corporation to the fullest extent permitted by Ohio law
against all expenses and liabilities reasonably incurred by or imposed by
him or her in connection with any proceeding or threatened  proceeding in
which he or she may become involved by reason of his or her being or having
been a director or officer.  Generally, Ohio permits such indemnification
provided that the person seeking to be indemnified has acted in good faith
and in a manner reasonably believed to be in or not opposed to the best
interests of the corporation, and with respect to any criminal action, had
no reasonable cause to believe his or her conduct was unlawful, so long as
no judgment or other final adjudication adverse to such person establishes
that his or her acts or omissions (i) were in breach of his or her duty of
loyalty to the corporation or its shareholders, (ii) were not in good faith
or involved a knowing violation of law, or (iii) resulted in his or her
receipt of an improper personal benefit.  The grant of indemnification in
the context of a derivative or other comparable lawsuit may have a circular
effect, inasmuch as any damages recovered in such action will be offset by
the cost of indemnification.

The CAMAX Articles of Incorporation provide that directors of the
corporation shall not be liable to its shareholder for monetary damages for
breaches of fiduciary duty; provided however, that such liability of a
director shall not be eliminated or limited to the extent provided by
applicable law. 


CERTAIN TRANSACTIONS

In connection with the 1994 merger of Point Control and CAMAX, on September
2, 1994, CAMAX entered into a consulting agreement (the "Consulting
Agreement") with Mr. Blakely.  Pursuant to the terms of the Consulting
Agreement, Mr. Blakely is required to devote no less than 450 hours, 325
hours and 200 hours of his time to the business of CAMAX during the first,
second and third twelve month periods following the date of the Consulting
Agreement, respectively.  In consideration of his efforts on behalf of
CAMAX, Mr. Blakely is to receive a consulting fee of $150 per hour. 
According to the terms of the Consulting Agreement, Mr. Blakely is required
to create and maintain distributor relationships, participate in trade
shows, produce and review marketing materials, develop background materials
for industry analysts and publications, maintain key customer relationships
and create future technologies.  In addition to Mr. Blakely's hourly
consulting fee, Mr. Blakely received $50,000 on the date of the Consulting
Agreement, $40,000 on the first anniversary of the Consulting Agreement and
is to receive $30,000 on the second anniversary of the Consulting Agreement
for his agreement not to compete with CAMAX during the term of the
Consulting Agreement.  The Consulting Agreement also requires that any
intellectual property conceived of or created by Mr. Blakely shall remain
the property of CAMAX and that Mr. Blakely shall not divulge to anyone or
use in any way any confidential or secret knowledge or information of CAMAX
which Mr. Blakely acquired or became acquainted with prior to the
termination of the Consulting Agreement for whatever reason.  The Consulting
Agreement will survive the Merger and become the binding obligation of both
Acquisition Corp. and Mr. Blakely in accordance with its terms following the
consummation of the Merger.

Years Ended December 31, 1992, 1993 and 1994

Net Sales.  CAMAX's net sales are derived from license fees for its software
products, from software maintenance and services fees and from other
sources.  Software sales are derived from software licensing fees and
software upgrades to more advanced modules .  Maintenance and services sales
are derived from software maintenance fees, updates to the current versions
of software and training fees.  Other sales are derived primarily from the
resale of hardware products.  The Company recognizes revenue from software
licensing fees in accordance with the provisions of American Institute of
Certified Public Accountants Statement of Position No. 91-1, Software
Revenue Recognition.  Software revenue from the sale of software licenses
is recognized upon shipment to the reseller, or to the end-user if the order
to CAMAX is from the end-user, if collection is probable and remaining
vendor obligations are insignificant.  Product returns and allowances (which
have not been significant through September 30, 1995) are estimated and
provided for at the time of sale.  Maintenance sales from ongoing software
maintenance agreements are recognized ratably over the term of the
maintenance agreement, which is typically 12 months.  Payments for
maintenance fees are generally received in advance.  Sales for training are
recognized when the services are performed.  Sales from the resale of
hardware products are recognized when the hardware products are shipped to
the end-user. 

Total net sales remained relatively constant at $18.1 million, $18.3 million
and $17.8 million in 1992, 1993 and 1994, respectively, representing an
increase of  1% from 1992 to 1993 and a decrease of 3% from 1993 to 1994. 
CAMAX derives its sales from three separate product lines--Camand, SmartCAM
and ManufacturingExpert.  CAMAX distributes the majority of its products
through a worldwide network of third party resellers.

Software  Sales.  Sales from software licenses were $12.6 million, $12.2
million and $11.7 million in 1992, 1993 and 1994, respectively, representing
decreases of 3% from 1992 to 1993 and 4% from 1993 to 1994.  Substantially
all of the period-to-period decline in software sales was due to a decrease
in the number of units of software shipped for the SmartCAM product line. 
Camand accounted for 44%, 50% and 50% and SmartCAM accounted for 56%, 50%
and 46% of total software sales for 1992, 1993 and 1994, respectively, and
ManufacturingExpert accounted for 4% of total software sales for 1994. 
CAMAX purchased the ManufacturingExpert product line in August 1994.

CAMAX anticipates that sales from software licenses will continue to
represent a substantial majority of its sales for the foreseeable future. 
CAMAX also believes that it will continue to experience intense competition
which could result in price reductions, reduced margins or loss of market
share, any of which could materially and adversely affect the Company's
business, operating results and financial condition.  In July 1995, CAMAX
announced a program to eliminate the sale and use of the ManufacturingExpert
product line and to convert these customers to Camand.  Management expects
that there will be declining sales from the sale of software licenses for
ManufacturingExpert in 1996 and no sales in 1997 and future periods.

Maintenance and Services Sales.  Maintenance and services sales were $3.4
million, $4.6 million and $5.5 million in 1992, 1993 and 1994, respectively,
representing increases of 33% from 1992 to 1993 and 21% from 1993 to 1994. 
The growth in each period was primarily attributable to an increase in the
number of customers in CAMAX's installed base purchasing software
maintenance agreements.  For the years, 1992, 1993 and 1994, maintenance and
services sales as a percentage of total net sales accounted for 19%, 25% and
31%, respectively.  CAMAX believes that prior growth in the rates of
increase for maintenance and services sales should not be relied upon as any
indication of growth rates for any future period.

Other Sales.  Other sales were $2.1 million, $1.5 million and $0.5 million
in 1992, 1993 and 1994, respectively, representing decreases of 25% from
1992 to 1993 and 65% from 1993 to 1994.  The decline in each period was
primarily attributable to a de-emphasis on the resale of hardware products
which began in 1993.  For the years, 1992, 1993 and 1994, other sales as a
percentage of net sales accounted for 11%, 8% and 3%, respectively.  During
1995, CAMAX ended its practice of selling hardware products and does not
expect to generate any significant hardware sales in future periods.

International Sales.  Sales outside of North America accounted for 31%, 31%
and 33% of total net sales in 1992, 1993 and 1994, respectively.  The
increase in international sales in 1994 was primarily attributable to an
increase in the number of international resellers marketing CAMAX's
products.  CAMAX intends to continue increasing the number of international
resellers and direct sales personnel within its international markets. 
There can be no assurance that CAMAX's investments in its international
sales and marketing operations will result in increased international sales.

Although exposure to currency fluctuations to date has been insignificant,
there can be no assurance that fluctuations in the currency exchange rates
in the future will not have an adverse impact on CAMAX's operations. 
Additional risks inherent in CAMAX's international business activities
include unexpected changes in regulatory requirements, tariffs and other
trade barriers, costs of localizing products for foreign countries, lack of
acceptance of localized products in foreign countries, longer accounts
receivable payment cycles, difficulties in collecting payment, difficulties
in managing international operations, potentially adverse tax consequences
including repatriation of earnings, reduced protection for intellectual
property and the burdens of complying with a wide variety of foreign laws. 
There can be no assurance that such factors will not have a material adverse
effect on CAMAX's future international sales and, consequently, on CAMAX's
business, operating results and financial condition.

Cost of Sales

Cost of Software Sales.  Cost of software sales consists primarily of third
party royalty fees, manuals, software amortization, product media and
duplication, packaging materials and shipping expenses.  Cost of software
sales was $0.9 million, $0.8 million and $2.2 million in 1992, 1993 and
1994, respectively, representing 8%, 7% and 19% of software sales for each
respective year.  The increase in the cost of software sales from 1993 to
1994 is primarily attributable to the amortization of the cost of the
ManufacturingExpert, acquired in 1994 (See Note 2 of Notes to Consolidated
Financial Statements), product line and the cost of royalties for third
party technology.  

In August 1994, CAMAX purchased the assets of the software product known as
ManufacturingExpert from Autodesk, Inc. ("Autodesk").  The purchase price
was $1.6 million which consisted of $0.3 million in cash, assumption of
liabilities of $0.1 and a noninterest-bearing note of $1.2 million issued
by CAMAX to Autodesk which requires three annual payments of $0.4 million
through 1997.  The purchase price was allocated as follows:  discount for
imputed interest, $0.2 million; services of Autodesk personnel during the
transition period, $0.6 million; and purchased software, $0.8 million.

CAMAX capitalizes software development costs in accordance with SFAS No. 86,
Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed.  Capitalization of software development costs begins
upon the establishment of technological feasibility of the product.  In
1994, CAMAX changed its software development process from a feature-based
release model to a time-based release model.  This development process
significantly reduced the extent of software production costs incurred after
the establishment of technological feasibility.  Because of this change,
CAMAX management believes the amount of any software development costs that
could be capitalized is immaterial. Accordingly, all software development
costs during 1994 were expensed as incurred.  Costs of $0.3 million and $0.5
million were capitalized in 1992 and 1993, respectively.  CAMAX estimated
that such costs had an economic life of two years.  Amortization expense of
$0.3 million, $0.4 million and $0.3 million has been included in cost of
software sales for 1992, 1993 and 1994, respectively.  There will be
amortization of approximately $0.1 million charged to cost of software sales
in 1995 to complete the amortization of the remaining balance of deferred
software development costs.   

Cost of Maintenance and Services Sales.  Cost of maintenance and services
sales consists primarily of the same types of costs as those incurred for
software sales, as well as costs for third party technology maintenance. 
Cost of maintenance and services sales was $0.1 million, $0.2 million and
$0.3 million in 1992, 1993 and 1994, respectively, representing 4%, 3% and
6% of maintenance and services sales for each respective year.  The increase
in the dollar amount of the cost of maintenance and services sales in each
successive year was due primarily to the increase in maintenance and
services sales as well as to an increase in the cost of software maintenance
on third party technology. 

Other Sales.  Cost of other sales consists primarily of the cost of third
party hardware and hardware maintenance purchased by CAMAX and resold to its
customers.  Cost of other sales was $1.5 million, $1.1 million and $0.4
million in 1992, 1993 and 1994, respectively, representing 75%, 69% and 66%
of other sales for each respective year.  The decrease in the dollar amount
of the cost of other sales in each successive year was due primarily to the
decrease in the other sales.  Management believes that the cost of other
sales will be insignificant in future periods.

Operating Expenses

Sales and Marketing.  Sales and marketing expenses consist primarily of
salaries, commissions and bonuses of sales and marketing personnel, travel
and entertainment expenses and promotional expenses.  Sales and marketing
expenses were $9.5 million, $9.8 million and $10.1 million, or 53%, 54% and
57% of total net sales, in 1992, 1993 and 1994, respectively.  The year-to-year
increases in dollar amount and as a percentage of total net sales was
primarily due to increases in marketing and promotional activities. 
Management believes that sales and marketing expenses will increase in
dollar amounts in future periods as it expands its sales and marketing in
international markets.

Research and Development.  Research and development expenses were $3.2
million, $3.9 million and $4.2 million in 1992, 1993 and 1994, or 18%, 21%
and 24% of total net sales, in 1992, 1993 and 1994, respectively.  The
increase in dollar amount in research and development expenses and as a
percentage of total net sales from 1992 to 1993 was primarily due to an
increase in the number of software engineers to develop product
enhancements.  The increase in dollar amount and as a percentage of net
sales from 1993 to 1994 was primarily due to the previously described change
in the software development process. 

General and Administrative.  General and administrative expenses were $1.7
million, $2.2 million and $3.1 million, or 9%, 12% and 18% of total net
sales, in 1992, 1993 and 1994, respectively.  The increase in dollar amount
in general and administrative expenses and as a percentage of total net
sales from 1992 to 1993 was primarily due to an increase in administrative
employees as well as the write-off of certain accounts receivable.  The
increase in dollar amount and as a percentage of total net sales from 1993
to 1994 was primarily due to severance payments made in connection with the
departure of CAMAX's former President and CEO in June 1994, as well as
legal, accounting and other costs associated with the merger of CAMAX and
Point Control Co. in September 1994.

Other Income (Expense)

Other income (expense) consists of the net effect of interest income,
interest expense and miscellaneous income and expense items.  Other expense
was $2,000, $18,000 and $26,000 in 1992, 1993 and 1994, respectively.  

Income Taxes

The effective tax rates for 1992, 1993 and 1994 were 13%, (20%) and (2%),
respectively.  These rates differ from the statutory rate primarily due to
the use of a net operating loss carryforward in 1992 (for CAMAX), the use
of both a net operating loss carryback (for Point Control) and a loss
carryforward (for CAMAX) in 1993 and a net operating loss (consolidated) in
1994.   

Effective January 1, 1993, CAMAX adopted SFAS No. 109, Accounting for Income
Taxes.  CAMAX elected to adopt the requirements of SFAS No. 109 as of
January 1, 1993, rather than retroactively restate prior financial
statements.  The cumulative effect as of January 1, 1993 of adopting SFAS
No. 109 was a credit to income of $1.0 million.  See Note 1 of Notes to
Consolidated Financial Statements.

As of December 31, 1994, CAMAX has net operating loss carryforwards of
approximately $9.8 million, research  and development tax credit
carryforwards of approximately $0.5 million and other tax credit
carryforwards of approximately $0.2 million.  The carryforwards expire in
varying amounts from 1998 to 2010.  There can be no assurance that the net
operating loss carryforwards and the various tax credit carryforwards will
be realized.  CAMAX expects that its effective tax rate for 1995 will also
be significantly below the statutory rate due to the use of net operating
loss carryforwards.  See Note 7 of Notes to Consolidated Financial
Statements.

Nine Months Ended September 30, 1994 and 1995

Net Sales

Total net sales increased by 8% from $13.2 million for the nine months
September 30, 1994 to $14.3 million for the nine months ended September 30,
1995.  Total net sales increased primarily due to sales of software licenses
for ManufacturingExpert (purchased from Autodesk in August 1994 as
previously described) and increased maintenance fees resulting from an
increasing number of CAMAX's customers purchasing software maintenance
agreements.  Sales derived through indirect distribution channels accounted
for the majority of CAMAX's total net sales for the nine months ended
September 30, 1994 and 1995.

Software Sales.  Sales from software licenses increased 12% from $8.7
million for the nine months ended September 30, 1994 to $9.7 million for the
nine months ended September 30, 1995.  The increase was primarily due to
sales of software licenses for ManufacturingExpert.  In the nine months
ended September 30, 1995, Camand accounted for 44%, SmartCAM accounted for
41% and ManufacturingExpert accounted for 15% of total software sales.

Maintenance and Services Sales.  Maintenance and services sales increased
10% from $4.1 million for the nine months ended September 30, 1994 to $4.5
million for the nine months ended September 30, 1995.  The growth was
primarily attributable to an increasing number of CAMAX's customers electing
to purchase software maintenance agreements.  As a percentage of total net
sales, maintenance and services sales remained consistent at 31% for each
of the nine months ended September 30, 1994 and 1995.

Other Sales.  Other sales decreased 92% from $0.5 million for the nine
months ended September 30, 1994 to less than $0.1 million for the nine
months ended September 30, 1995.  The decrease was primarily attributable
to a de-emphasis by CAMAX on the resale of hardware products and related
maintenance.  As a percentage of total net sales, other sales decreased from
3% for the nine months ended September 30, 1994 to less than 1% for the nine
months ended September 30, 1995.

International Sales.  Sales outside of North America as a percentage of
total net sales increased from 32% for the nine months ended September 30,
1994 to 35% for the nine months ended September 30, 1995.  The increase was
primarily due to the increase in the number of international resellers
marketing CAMAX's products.

Cost of Sales

Cost of Software Sales.  Cost of software sales increased from $1.0 million
for the nine months ended September 30, 1994 to $1.1 million for the nine
months ended September 30, 1995, representing 11% and 12%, respectively, of
software sales for each period.  The increase in dollar amount was primarily
due to the increase in sales of software licenses.

Cost of Maintenance and Services Sales.  Cost of maintenance and services
sales increased from $0.2 million for the nine months ended September 30,
1994 to $0.3 million for the nine months ended September 30, 1995,
representing 5% and 7%, respectively, of maintenance and services sales. 
The increase in dollar amount and as a percentage of maintenance and
services sales was primarily due to the increases in maintenance and
services sales and the cost of maintenance on third party technology.

Cost of Other Sales.  Cost of other sales decreased from $0.3 million for
the nine months ended September 30, 1994 to less than $0.1 million for the
nine months ended September 30, 1995, representing 67% and 71%,
respectively, of other sales.  The decrease in dollar amount was due
primarily to the decrease in related other sales.

Operating Expenses

Sales and Marketing.  Sales and marketing expenses increased by 9% from $7.1
million for the nine months ended September 30, 1994 to $7.8 million for the
nine months ended September 30, 1995, representing 54% of total net sales
for each period.  The increase in sales and marketing expenses in dollar
amount was primarily due to increased costs for reseller development and
advertising and promotional costs. 

Research and Development.  Research and development expenses decreased by
2% from $3.0 million for the nine months ended September 30, 1994 to $2.9
million for the nine months ended September 30, 1995, representing 22% and
20%, respectively, of total net sales.  The decrease in research and
development expenses both in dollar amount and as a percentage of total net
sales was primarily due to a fewer number of software engineers devoting
time to development efforts in 1995 then in 1994.

General and Administrative.  General and administrative expenses decreased
by 32% from $2.4 million for the nine months ended September 30, 1994 to
$1.7 million for the nine months ended September 30, 1995, representing 18%
and 12%, respectively, of total net sales.  The decrease in general and
administrative expenses both in dollar amount and as a percentage of total
net sales was primarily due to severance payments made in connection with
the departure of CAMAX's former President and Chief Executive Officer in
June 1994, as well as legal, accounting and other costs associated with the
merger of CAMAX and Point Control Co. in September 1994.

Other Income (Expense)

Other expense was $9,000 for the nine months ended September 30, 1994 as
compared to other income of $17,000 for the nine months ended September 30,
1995, primarily due to increased interest income generated from higher cash
balances.

Income Taxes

Income tax expense for the nine months ended September 30, 1994 was $10,000
as compared to $30,000 for the nine months ended September 30, 1995,
primarily due to an increase in income before income taxes.

Liquidity and Capital Resources

From its inception through 1987, CAMAX financed its operations primarily
through private sales of common stock, totaling over $14 million,and bank
loans.  Since 1988, CAMAX has financed its operations primarily through cash
generated from operations.  In 1992, 1993 and 1994 and the nine months ended
September 30, 1995, $1.8 million, $1.1 million, $1.9 million and $1.1
million, respectively, was generated by operations.  Cash provided by
operations has been primarily the result of net income, adjusted for
depreciation and amortization, generated in each year, except in 1994 where
the collection of accounts receivable provided $1.8 million of cash.

CAMAX's investing activities consist primarily of purchases of property and
equipment.  In 1992, 1993, 1994 and the nine months ended September 30,
1995, CAMAX used $0.9 million, $0.7 million, $0.9 million and $1.6 million,
respectively, to purchase property and equipment, primarily computer
hardware and software.  In addition, CAMAX capitalized software development
costs of $0.3 and $0.5 in 1992 and 1993, respectively, and allocated $0.8
million to purchased software from the purchase of the ManufacturingExpert
product line in 1994.  Beginning in 1994, CAMAX changed its software
development process which resulted in CAMAX incurring immaterial costs after
achievement of technological feasibility.  Management expects that the rate
of purchases of property and equipment will decrease in 1996 to the
approximate 1992-1994 levels.  CAMAX's principal commitments consist
primarily of leases on its facilities in Minneapolis, Minnesota and Eugene,
Oregon.  See Note 5 of Notes to Consolidated Financial Statements.

At September 30, 1995, CAMAX had $2.7 million in cash, cash equivalents and
investments and $1.8 million of working capital.  CAMAX had an unsecured,
noninterest-bearing note outstanding to Autodesk in connection with CAMAX's
purchase of the ManufacturingExpert product line with a principal balance
as of September 30, 1995 of $704,000.  The terms of the note include an
acceleration in the payment of the note in the event of a change in control
of CAMAX.  

CAMAX also had a term loan from a bank that was secured by certain assets
of CAMAX.  The loan bears interest at the bank's reference rate plus 1.625%
(9.75% at September 30, 1995) and expires in November 1998.  The principal
balance of this term loan was $486,000 on September 30, 1995.  At September
30, 1995, CAMAX had outstanding $527,000 in remaining obligations for
capitalized equipment leases which expire in varying timeframes through the
first quarter of 2000.  See Note 4 of Notes to Consolidated Financial
Statements.

CAMAX has short-term lines of credit with two banks for borrowings of up to
$500,000 and $750,000, respectively.  Borrowings under the $500,000 line of
credit agreement bear interest at 1.0% over the reference rate as
established by First Bank Minneapolis (9.75% at September 30, 1995). 
Borrowings under the $750,000 line of credit agreement bear interest at the
bank's reference rate plus 1% (9.75% at September 30, 1995) with a floor of
8.75%.  As part of the $750,000 borrowing arrangement, CAMAX must maintain
a $50,000 compensating balance.  Borrowings under the agreements are
collateralized by substantially all of CAMAX's assets.  Both agreements
contain certain restrictive covenants which, among other things, require
CAMAX to maintain specified levels of net worth.  As of September 30, 1995,
CAMAX had no borrowings outstanding under either agreement.

CAMAX's days sales outstanding were 64, 61, 56 and 66 at December 31, 1992,
1993 and 1994 and September 30, 1995, respectively.  The decrease in days
sales outstanding at December 31, 1994 was primarily due to a decline in
sales in December 1994 from historical levels.

To date, CAMAX has not invested in derivative securities or any other
financial instruments that involve a high level of complexity or risk.

                             LEGAL MATTERS

Dinsmore & Shohl, Cincinnati, Ohio, counsel for SDRC, has rendered its
opinion that the shares of SDRC Common Stock to be issued to the
shareholders of CAMAX in connection with the Merger have been duly
authorized and, if issued pursuant to the Merger Agreement, will be validly
issued, fully paid and non-assessable under the current laws of the State
of Ohio.  Such firm will also render its opinion with respect to certain
federal income tax consequences of the Merger to SDRC, CAMAX and the
shareholders of CAMAX.

John E. McDowell, a partner in Dinsmore & Shohl, is a director of SDRC.  As
of December 31, 1995, partners of Dinsmore & Shohl and attorneys employed
by such firm beneficially owned 105,906 shares of SDRC Common Stock.

INDEPENDENT AUDITORS' REPORT


Board of Directors and Shareholders
CAMAX Manufacturing Technologies, Inc.
Minneapolis, Minnesota

We have audited the consolidated balance sheets of CAMAX Manufacturing
Technologies, Inc. and subsidiaries (the Company) as of December 31, 1993
and 1994 and the related consolidated statements of operations,
shareholders' equity, and cash flows for each of the three years in the
period ended December 31, 1994.  These consolidated financial statements are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on the consolidated financial statements based on our
audits.  The consolidated financial statements give retroactive effect to
the merger of CAMAX Systems, Inc. and Point Control Co., which has been
accounted for as a pooling of interest as described in Note 2 to the
consolidated financial statements.  We did not audit the balance sheet of
Point Control Co. as of December 31, 1993 or the related statements of
operations, shareholders' equity, and cash flows of Point Control Co. for
the years ended December 31, 1992 and 1993, which statements reflect total
assets of $3,915,833 as of December 31, 1993 and total net revenues of
$8,933,436 and $8,705,647 for the years ended December 31, 1992 and 1993. 
Those statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts
included for Point Control Co. for 1992 and 1993, is based solely on the
report of such other auditors.

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 consolidated financial
statements are free of material misstatement.  An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
consolidated 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 and the report of the other auditors provide a reasonable
basis for our opinion.

In our opinion, based on our audits and the report of the other auditors,
the consolidated financial statements referred to above present fairly, in
all material respects, the financial position of CAMAX Manufacturing
Technologies, Inc. and subsidiaries at December 31, 1993 and 1994 and the
results of their operations and their cash flows for each of the three years
in the period ended December 31, 1994 in conformity with generally accepted
accounting principles.

As discussed in Note 1 to the consolidated financial statements, in 1993 the
Company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes."

Report of Independent Accountants

To the Board of Directors
Point Control Co.:

We have audited the consolidated balance sheet of Point Control Co. and
subsidiaries as of December 31, 1993, and the related consolidated
statements of operations, shareholders' equity and cash flows for each of
the two years in the period ended December 31, 1993.  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 used 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.

In our opinion, the financial statements referred to above (not presented
separately herein) present fairly, in all material respects, the
consolidated financial position of Point Control Co. and subsidiaries as of
December 31, 1993, and the consolidated results of their operations and
their cash flows for each of the two years in the period ended December 31,
1993 in conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Company changed its
method of accounting for income taxes in 1992.

equity, and cash flows for the nine-month periods ended September 30, 1995
and 1994 are unaudited.  In the opinion of management, such unaudited
consolidated financial statements include all adjustments, consisting of
only normal, recurring accruals necessary for a fair presentation thereof. 
The results of operations for any interim period are not necessarily
indicative of the results for the year.

Cash and Cash Equivalents - Cash and cash equivalents include temporary cash
investments stated at cost, which approximates market.  The Company
considers all investments with maturities of three months or less when
purchased to be cash equivalents.

Investments - The Company invests in debt securities issued by the U.S.
Treasury, certificates of deposit of financial institutions, and commercial
paper.  All securities have been classified as held to maturity under
Statement of Financial Accounting Standards (SFAS) No. 115 due to the
Company's intent and ability to hold these investments to maturity.  These
investments are recorded at amortized cost.  As fair market value
approximates amortized cost, the unrealized holding gain or loss at each
period end was not significant.

Concentrations of Credit Risk - Financial instruments which potentially
expose the Company to concentrations of credit risk, as defined by SFAS No.
105, consist primarily of trade accounts receivable.  The Company's accounts
receivable are primarily due from its dealer network.  The Company manages
this credit risk by evaluating creditworthiness regularly.  The Company does
not require collateral for its trade accounts receivable.

Inventory - Inventories, which consist of software manuals and supplies, are
valued at the lower of average cost or market.

Property - Property is stated at cost.  Depreciation, which includes the
amortization of assets recorded under capital leases, is computed using the
straight-line method over the asset's estimated useful life or the term of
the capital lease, whichever is shorter.

Capitalized lease amounts included in property were $208,000 and $304,000
which were net of accumulated amortization of $352,000 and $517,000 at
December 31, 1993 and 1994, respectively.

Deferred Computer Software Development Costs - Under the criteria set forth
in the SFAS No. 86, "Accounting for the Costs of Computer Software to Be
Sold, Leased, or Otherwise Marketed," capitalization of software development
costs begins upon the establishment of technological feasibility of the
product.  The establishment of technological feasibility and the ongoing
assessment of the recoverability of these costs require considerable
judgment by management with respect to certain external factors, including,
but not limited to, anticipated future gross product revenues, estimated
economic product lives, and changes of software and hardware technology.

In 1994, the Company changed its software development process from a
feature-based release model to a time-based release model.  This development
process significantly reduced the extent of software production costs
incurred after the establishment of technological feasibility.  Because of
this change, the Company's management believes the amount of any software
development costs that could be capitalized is immaterial.  Accordingly, all
software development costs after December 31, 1993 were expensed as
incurred.

Costs of $308,000 and $483,000 were capitalized in 1992 and 1993,
respectively, and were included in Deferred Software Development Costs.  The
Company estimated that such costs had an economic life of two years. 
Amortization expense of $340,000, $353,000, and $304,000 has been included
in cost of sales for 1992, 1993, and 1994, respectively.

Impairment of Long-Lived Assets - Management of the Company periodically
reviews the carrying value of deferred software development costs and other
intangible assets for potential impairment by comparing the carrying value
of these assets with their related expected future net cash flows.  Should
the sum of the related expected future net cash flows be less than the
carrying value, management will determine whether an impairment loss should
be recognized.  An impairment loss would be measured by the amount by which
the carrying value of the asset exceeds the fair value of the asset.  To
date, except for the writeoff of ManufacturingExpert as discussed in Note
2, management has determined that no impairment of these assets exists.

Revenue Recognition - Revenue from the sale of software licenses is
recognized when the product is shipped to the customer.  Maintenance revenue
is recognized on a monthly basis over the life of the maintenance agreement. 
Revenue from consulting services is recognized when the services are
provided.  Sales outside of North America accounted for 31%, 31% and 33% of
total net sales in 1992, 1993 and 1994, respectively.

Income Taxes - Effective January 1, 1993, the Company adopted SFAS No. 109,
Accounting for Income Taxes.  The Company elected to adopt the requirements
of SFAS No. 109 as of January 1, 1993 rather than retroactively restate
prior financial statements.  Prior to the adoption of SFAS No. 109, the
Company followed the provisions of SFAS No. 96, "Accounting for Income
Taxes."  Under SFAS No. 109, deferred income taxes are recognized for tax
consequences in future years of differences between tax bases of assets and
liabilities and their financial reporting amounts at each period end based
on statutory tax rates applicable to periods in which the differences are
expected to affect taxable income.  As a result of changes in requirements
for the recognition of deferred tax assets contained in SFAS No. 109, the
Company recorded a tax benefit primarily related to existing operating loss
carryforwards.  The cumulative effect as of January 1, 1993 of adopting SFAS
No. 109 was a credit to income of $975,567.

Earnings (Loss) Per Common and Common Equivalent Share - Earnings (loss) per
common and common equivalent share were calculated by dividing net income
(loss) by the weighted average common and common equivalent shares
outstanding during each period.  Common equivalent shares, using the
treasury stock method, include the dilutive effect of all outstanding common
stock options.

Use of Estimates in the Preparation of Financial Statements - The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure
of contingent assets and liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting
period.  Actual results could differ from those estimates.

Reclassifications - Certain 1992 and 1993 amounts have been reclassified to
conform with presentations in the 1994 financial statements.

2. BUSINESS MERGER AND PRODUCT LINE PURCHASE

 Merger with Point Control Co.:

On August 22, 1994, CAMAX Systems, Inc. (CAMAX) and Point Control Co. (PCC)
signed a definitive agreement to merge PCC into CAMAX, which resulted in PCC
becoming a wholly owned subsidiary of CAMAX effective September 2, 1994. 
Under the terms of the agreement, PCC shareholders received 17.75 shares of
CAMAX's common stock for each PCC share and an equivalent conversion for
each PCC stock option outstanding.  Accordingly, CAMAX issued 7,008,520
shares of its common stock for all the outstanding shares of PCC common
stock.  On December 9, 1994, the shareholders of CAMAX voted to amend its
Articles of Incorporation to change the name of the Company to CAMAX
Manufacturing Technologies, Inc.

The merger qualified as a tax-free reorganization and was accounted for as
a pooling of interests.  Accordingly, the Company's consolidated financial
statements have been restated to give retroactive effect to the merger of
CAMAX and PCC for all periods presented.

The combined results include reclassifications to conform the financial
statement presentation between the two companies.  These reclassifications
had no effect on net income (loss) or shareholders' equity as previously
reported by CAMAX or PCC, other than restating the $24,433 cumulative effect
for the adoption of SFAS No. 109 for PCC from fiscal 1992 as previously
reported to fiscal 1993.

Transaction costs relating to the merger of the two companies, which were
expensed in 1994, consist primarily of professional fees.  The costs to
combine the two organizations include provisions for severance costs
relating to the streamlining of the administrative, sales, and marketing
functions.

Purchase of ManufacturingExpert Assets:

On August 9, 1994, the Company purchased the assets for the software product
known as ManufacturingExpert from Autodesk Inc. (Autodesk).  The purchase
price was $1,568,000, which was paid with a down payment of $300,000 in
cash, assumption of $68,000 in liabilities, and issuance of a noninterest-
bearing note for $1,200,000 to Autodesk which requires three annual payments
of $400,000 through 1997 (see Note 4).  The terms of the note include an
acceleration of the note's maturity in the event of a change in control of
the Company.  The note has been discounted in the financial statements at
an imputed interest rate of 9%.  The purchase price was allocated as
follows:

Discount for imputed interest                              $  187,000
Services of Autodesk personnel during transition period       615,000
Value of purchased software                                   766,000
                                                           ----------
                                                           $1,568,000
                                                           ----------
                                                           ----------
The discount is being amortized over the note term as interest expense.  The
cost of the services of Autodesk personnel was expensed ratably over a six-month
period beginning August 9, 1994, the period over which such services
were rendered.  Operating expenses for 1994 and for the nine-months ended
September 30, 1995 include $506,000 and $109,000, respectively for these
transition team services.  The purchased software was amortized completely
during 1994, which is included in cost of sales, because of management's
determination that the expected future net cash flows would not support the
carrying value of this software.

3. LINE OF CREDIT

The Company has short-term lines of credit with two banks for borrowings up
to $500,000 and $750,000, respectively.  Borrowings under the $500,000 line
of credit agreement bear interest at 1.0% over the reference rate as
established by First Bank Minneapolis (8.5% at December 31, 1994). 
Borrowings under the agreement are limited to the lesser of $500,000 or the
Company's borrowing base, which consists of a specified percentage of
certain accounts receivable.  Borrowings under the agreement are secured by
substantially all of the Company's assets.  At December 31, 1994, the
Company had no borrowings outstanding under this line of credit agreement. 
The line of credit agreement contains certain restrictive covenants which,
among other things, require the Company to maintain net worth in an amount
at least equal to two times its obligations and certain indebtedness to the
bank.

The $750,000 line of credit is collateralized with accounts receivable,
inventory, equipment, and general intangibles of PCC.  The interest rate is
variable, based on the bank's reference rate (8.5% at December 31, 1994),
plus 1%, with a floor of 8.75%.  As part of the borrowing arrangement, PCC
is required to maintain a $50,000 compensating balance.  At December 31,
1994, PCC had no borrowings outstanding under this line of credit agreement. 
In addition to a guarantee by the Company, the line of credit agreement
contains certain restrictive covenants which, among others, require PCC to
maintain net worth of not less than $800,000 and a ratio of liabilities to
net worth of less than 3 to 1.  As of December 31, 1994, PCC was in
technical violation of these covenants; however, the bank provided a waiver
of the violations.  In June 1995, the covenants for the line of credit were
renegotiated.

4. LONG-TERM DEBT

Long-term debt at December 31 consists of the following:
                                                              1993     1994

Less current maturities                                    262,357     625,606
                                                           -------   ---------
                                                          $702,785  $1,303,718
                                                          --------   ---------
                                                          --------   ---------
       

Various loan agreements and capitalized leases are collateralized by the
pledge of certain equipment.  Total long-term debt maturities at December
31, 1994 are approximately $626,000 in 1995, $570,000 in 1996, $547,000 in
1997, $157,000 in 1998, and $30,000 in 1999.

5. LEASE COMMITMENTS

The Company leases its facilities and certain equipment under operating
leases with terms of up to 72 months.  Rent expense applicable to operating
leases was $678,000 in 1992, $747,000 in 1993, and $769,000 in 1994.  At
December 31, 1994, the future minimum rental payments required by
noncancelable operating leases are:  1995, $420,000; 1996, $420,000; 1997,
$407,000; 1998, $344,000; 1999, $348,000; and 2000, $61,000.

6. STOCK PLANS

Stock Option Plans - Under a 1985 Incentive Stock Option Plan, options for
175,000 shares of common stock may be granted at 100% of fair market value
at date of grant as determined by the Board of Directors.  Options are
exercisable at a rate determined by the Board of Directors and expire ten

                                ARTICLE 2.
                            CONVERSION OF SHARES

Section 2.1 Conversion Ratio.  All of the shares of CAMAX Common Stock
issued and outstanding as of the close of business on the business date
immediately prior to the Effective Date shall, in the aggregate, without any
action on the part of Surviving Corporation or any holder of such shares,
be converted by the Merger into shares of SDRC Common Stock without par
value ("SDRC Common Stock") having a total value of $30,000,000 (the "Total
Value").  The total number of shares of SDRC Common Stock to be issued shall
be determined by dividing the Total Value by the "Applicable Value Per Share
of SDRC Common Stock."  The "Applicable Value Per Share of SDRC Common
Stock" shall be the average of the last sale prices of the SDRC Common Stock
as reported on the Nasdaq National Market for the 20-trading day period
ending on the fifth trading day prior to the Effective Date (the "Valuation
Period").  Of the total number of shares of SDRC Common Stock so determined,
10% thereof shall be set aside for retention under Section 2.2 below. Each
individual share of CAMAX Common Stock issued and outstanding as of the
close of business on the business date immediately prior to the Effective
Date shall be converted into that number of shares of SDRC Common Stock
equal to the total number of shares of SDRC Common Stock to be issued in the
Merger as provided above (less the number of shares retained pursuant to
Section 2.2) divided by the total number of shares of CAMAX Common Stock
issued and outstanding as of the close of business on the business date
immediately prior to the Effective Date; provided, however, that no
fractional shares of SDRC Common Stock shall be issued pursuant to the
Merger and in lieu thereof cash shall be paid for fractional shares that
would otherwise be issued, in accordance with Section 2.3 below.

Section 2.2 Retention of Shares.  From and after the Effective Date, SDRC
shall retain that number of shares of SDRC Common Stock which represents 10%
of the total shares to be issued to the CAMAX shareholders upon consummation
of the Merger, in accordance with the conversion ratio set forth in Section
2.1 of this Agreement, which SDRC shall have the option of redeeming as
payment for any amounts due SDRC or the Surviving Corporation pursuant to
Article 10 of this Agreement (the "Retention Shares").  For the purposes of
any such redemption by SDRC, the redeemed shares shall be valued at the
Applicable Value Per Share of SDRC Common Stock. 

Upon the earlier of (i) the date that SDRC files its Annual Report on Form
10-K for the year ended December 31, 1996 or (ii) the first anniversary of
the Closing Date, as defined herein, (the "Retention Period") SDRC shall
distribute any Retention Shares not previously redeemed to the CAMAX
shareholders on a pro rata basis based upon their percentage ownership of
CAMAX Common Stock immediately prior to the Effective Date in the same
manner as provided in the last sentence of Section 2.1 above.

Section 2.3 Exchange of Certificates.  After the Effective Date, each holder
of a certificate or certificates for shares of CAMAX Common Stock, upon
surrender of the same duly transmitted to SDRC's stock transfer agent (or
in lieu of surrendering such certificates in the case of lost, stolen,
destroyed or mislaid certificates, upon execution of such documentation as
may be reasonably required by SDRC's stock transfer agent), shall be
entitled to receive in exchange therefor a certificate or certificates
representing the number of whole shares of SDRC Common Stock into which such
holder's shares of CAMAX Common Stock shall have been converted by the
Merger, less that proportion of the Retention Shares attributable to such
shareholder, plus a cash payment for any fraction of a share to which the
holder is entitled, in lieu of such fraction of a share, equal in amount to
the product resulting from multiplying such fraction by the Applicable Value
Per Share of SDRC Common Stock.  Until so surrendered, each outstanding
certificate that prior to the time the Merger becomes effective represented
shares of CAMAX Common Stock shall be deemed for all corporate purposes to
evidence ownership of the number of full shares of SDRC Common Stock into
which the same shall have been converted; provided, however, that dividends
or distributions otherwise payable with respect to shares of SDRC Common
Stock into which CAMAX Common Stock shall have been so converted shall be
paid with respect to such shares only when the certificate  or certificates
evidencing any such shares of CAMAX Common Stock shall have been so
surrendered (or in lieu of surrendering such certificates in the case of
lost, stolen, destroyed or mislaid certificates, upon execution of such
documentation as may be reasonably required by SDRC), and, thereupon, any
such dividends and distributions shall be paid, without interest, to the
holder entitled thereto, subject however to the operation of any applicable
escheat or similar laws relating to unclaimed funds.

Section 2.4  Dissenting Shares.

  (a) Notwithstanding anything in this Agreement to the contrary, if Section
302A.471 of the Minnesota Business Corporation Act shall be applicable to
the Merger, shares of CAMAX Common Stock that are issued and outstanding
immediately prior to the Effective Date and which are held by shareholders
who have not voted such shares in favor of the Merger, who shall have
delivered, prior to any vote on the merger, a written demand for the fair
value of such shares in the manner provided in Section 302A.473 of the
Minnesota Business Corporation Act and  who, as of the Effective Date, shall
not have effectively withdrawn or lost such right to dissenters' rights
("Dissenting Shares") shall not be converted into or represent a right to
receive shares of SDRC Common Stock pursuant to Section 2.1 hereof, but the
holders thereof shall be entitled only to such rights as are granted by
Section 302A.473 of the Minnesota Business Corporation Act.  Each holder of
Dissenting Shares who becomes entitled to payment for such shares pursuant
to Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act
shall receive payment therefor from the Surviving Corporation in accordance
with the Minnesota Business Corporation Act; provided, however, that if such
holder of Dissenting Shares shall have effectively withdrawn such holder's
demand for appraisal of such shares or lost such holder's right to appraisal
and payment of such shares under Section 302A.473 of the Minnesota Business
Corporation Act, such holder or holders (as the case may be) shall forfeit
the right to appraisal of such shares and each such share shall thereupon
be deemed to have been canceled, extinguished and converted, as of the
Effective Date, into and represent the right to receive payment from the
Surviving Corporation of the shares of SDRC Common Stock, as provided in
Section 2.1 hereof.

  (b) CAMAX shall give SDRC (i) prompt notice of any written demand for fair
value, any withdrawal of a demand for fair value and any other instrument
served pursuant to Section 302A.473 of the Minnesota Business Corporation
Act received by CAMAX, and (ii) the opportunity to direct all negotiations
and proceedings with respect to demands for fair value under such
negotiations and proceedings with respect to demands for fair value under
such Section 302A.473 of the Minnesota Business Corporation Act.  CAMAX
shall not, except with the prior written consent of SDRC, voluntarily make
any payment with respect to any demand for fair value or offer to settle or
settle any such demand.

Section 2.5 Plan Stock Options.

  (a) At the Effective Date, each outstanding option to purchase shares of
CAMAX Common Stock (individually, a "Plan Option" and, collectively, the
"Plan Options") issued pursuant to the Point Control Co. 1987 Incentive
Stock Option Plan, CAMAX Systems, Inc. 1985 Incentive Stock Option Plan,
CAMAX Systems, Inc. 1987 Non-Qualified Stock Option Plan, CAMAX
Manufacturing Technologies, Inc. 1995 Long-Term Incentive and Stock Option
Plan and CAMAX Manufacturing Technologies, Inc. 1995 Directors' Stock Option
Plan (individually, a "Plan" and, collectively, the "Plans"), whether vested
or unvested, shall be assumed by SDRC.  Each Plan Option shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Plan Option, the same number of shares of SDRC Common
Stock as the holder of such Plan Option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full
immediately prior to the Effective Date (rounded down to the nearest whole
share), at a price per share equal to (x) the aggregate exercise price for
the shares of CAMAX Common Stock otherwise purchasable pursuant to such Plan
Option divided by (y) the number of full shares of SDRC Common Stock deemed
purchasable pursuant to such Plan Option; provided, however, that in the
case of any option to which Section 421 of the Code applies by reason of its
qualification under Section 422 of the Code ("qualified stock options"), the
option price, the number of shares purchasable pursuant to such option and
the terms and conditions of exercise of such option shall be determined in
order to comply with Section 424(a) of the Code.  The stock appreciation
rights attached to each Plan Option, if any (the "Stock Appreciation
Rights"), shall attach to the option to acquire SDRC Common Stock into which
such Plan Option is converted pursuant to the preceding sentence, on the
same terms and conditions as were applicable under such Plan Option.

  (b) As soon as practicable after the Effective Date, SDRC shall deliver
to the holders of Plan Options appropriate notices setting forth such
holders' rights pursuant to the Plan and the agreements evidencing the
grants of such Plan Options shall continue in effect on the same terms and
conditions (subject to the adjustments required by this Section 2.5) after
giving effect to the Merger and the assumption by SDRC as set forth above. 
SDRC shall comply with the terms of the Plan and ensure, to the extent
required by, and subject to the provisions of, such Plan, that Plan Options
which qualified as qualified stock options prior to the Effective Date
continue to qualify as qualified stock options of SDRC after the Effective
Date.

 (c) SDRC shall take all corporate action necessary to reserve for issuance
a sufficient number of shares of SDRC Common Stock for delivery upon
exercise of Plan Options assumed by it in accordance with this Section 2.5
immediately after the Effective Date.

Section 2.6 Other Stock Options.

 (a) At the Effective Date, each outstanding option to purchase shares of
CAMAX Common Stock (individually, a "Stock Option" and, collectively, the
"Stock Options") issued other than pursuant to the Plan, whether vested or
unvested, shall be assumed by SDRC.  Each Stock Option shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Stock Option, the same number of shares of SDRC Common
Stock as the holder of such Stock Option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full
immediately prior to the Effective Date, at a price per share equal to (x)
the aggregate exercise price for the shares of CAMAX Common Stock otherwise
purchasable pursuant to such Stock Option divided by (y) the number of full
shares of SDRC Common Stock deemed purchasable pursuant to such Stock
Option.

  (b)  As soon as practicable after the Effective Date, SDRC shall deliver
to the holders of Stock Options appropriate notices setting forth such
holders' rights and the agreements evidencing the grants of such Stock
Options shall continue in effect on the same terms and conditions (subject
to the adjustments required by this Section 2.6 after giving effect to the
Merger and the assumption by SDRC as set forth above).

  (c) SDRC shall take all corporate action necessary to reserve for issuance
a sufficient number of shares of SDRC Common Stock for delivery upon

forth on Schedule 3.15, there is no breach or violation of, or default under
any material contract, agreement or commitment, and no event has occurred
which, with notice or lapse of time or both, would constitute a breach,

cancellation, prepayment or acceleration under any such contract, agreement
or commitment.

Material Adverse Effect on CAMAX's business, and there is no claim, suit,
action or proceeding pending or, to the knowledge of CAMAX, threatened

or (ii) challenging CAMAX's or its Subsidiaries' ownership of or right to
use or the validity of any Intellectual Property.  To CAMAX's knowledge,

Benefit Plan under Section 419(A)(f)(7)(C) of the Code.  Each participant
and beneficiary under each of the Benefit Plans, and each of their spouses
and dependents, has received (i) all notices and reports required by ERISA
within the required deadlines, and (ii) adequate and timely notice of all
elections and options permitted under the Benefit Plans.  All required
contributions have been made to each of the Benefit Plans.

  3.19.2 Violations.  CAMAX and its Subsidiaries have not engaged in any
transaction which could result in a material liability under Section 409 of
ERISA or Section 4975 of the Code.  The execution and delivery of this
Agreement will not cause the termination of any of the Benefit Plans,
involve any prohibited transaction within the meaning of Section 406 of
ERISA or Section 4975 of the Code, nor constitute a breach of fiduciary
responsibility with respect to the Benefit Plans.

  3.19.3 Documents.  CAMAX has delivered to SDRC: (i) all determination
letters issued by the IRS within the past five years with respect to the
Benefit Plans, and the requests therefor; (ii) any and all documents

account of or for (i) overtime pay, other than overtime pay for the current
payroll period, (ii) wages or salary for any period other than the current
payroll period, (iii) vacation or time off (or pay in lieu thereof), other

maintained liability coverage with financially sound and reputable insurance
carriers in amounts which are reasonable in light of the business of CAMAX
and its Subsidiaries and its  claims experience.  CAMAX and its Subsidiaries

has received from an independent investment banking firm an opinion, in form

shareholders of CAMAX from a financial point of view and such fairness
opinion shall not have been withdrawn as of the Effective Date.

Letter, CAMAX has received from tax counsel an opinion, in form and
substance satisfactory to CAMAX, a copy of which is attached hereto as

transaction under the Code and such opinion shall not have been withdrawn
as of the Effective Date.

Section 3.30 Additional Tax Matters.  To the knowledge of CAMAX and its
Subsidiaries, neither CAMAX nor any of its Subsidiaries, affiliates or
shareholders has taken or agreed to take any action that would prevent the
Merger from constituting a transaction qualifying as a reorganization under
Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code.

Section 3.31 Corporate Power and Authorization.  The directors of CAMAX, by
resolution adopted by the vote of the directors at a meeting duly called and
held in accordance with applicable law, have duly approved this Agreement,
and have directed that this Agreement be submitted to a vote of CAMAX's
shareholders at a special meeting of shareholders to be called for that
purpose, all in accordance with and as required by law and in accordance
with the Articles of Incorporation and Bylaws of CAMAX.  CAMAX has the
corporate power and authority to enter into this Agreement and to carry out
its obligations hereunder subject to certain required regulatory and
shareholder approvals.  This Agreement, when executed and delivered, will
have been duly authorized and will constitute valid and binding obligations
of CAMAX, enforceable in accordance with their respective terms, except to
the extent that (i) enforceability thereof may be limited by insolvency,
reorganization, liquidation, bankruptcy, readjustment of debt or other laws
of general application relating to or affecting the enforcement of
creditors' rights, and (ii) the availability of certain remedies may be

Attention: Mr. Robert J. Majteles, President and Chief Executive Officer
  Mr. Gregory S. Furness, Executive Vice President and Chief Financial
Officer

Gentlemen:

You have requested our opinion as to the fairness, from a financial point
of view, to the shareholders of CAMAX Manufacturing Technologies, Inc.
("CAMAX" or the "Company"), of the financial terms of the proposed Merger
(the "Merger") between CAMAX and SDRC Systems, Inc., a wholly-owned
subsidiary of Structural Dynamics Research Corporation ("SDRC"). 
Capitalized terms used herein shall have the meaning used in the Agreement
and Plan of Merger ("Agreement") dated January 16, 1996 unless otherwise
defined herein.

Pursuant to the Agreement, the outstanding shares of CAMAX will be converted
into and represent the right to receive such number of shares of SDRC Common
Stock having a Total Value of $30,000,000.  The total number of shares of
SDRC Common Stock to be issued shall be determined by dividing the Total
Value by the Applicable Value Per Share of SDRC Common Stock.  The
Applicable Value Per Share of SDRC Common Stock shall be the average of the
last sale prices of the SDRC Common Stock as reported on the Nasdaq National
Market for the 20 trading day period ending on the fifth trading day prior
to the Effective Date.  In order to render the opinion herein, we have
assumed the Applicable Value Per Share of SDRC Common Stock to be $26.00
which assumption is based on the provisions of the Agreement as if the
Effective Date (which is expected to occur on March 31, 1996) were the date
hereof.

Additionally, the outstanding CAMAX Stock Options and Plan Options, whether
vested or unvested, shall be assumed by SDRC and shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such CAMAX Plan, the same number of shares of SDRC Common
Stock as the holder of such Stock Options or Plan Options would have been
entitled to receive pursuant to the Merger had such holder exercised such
option in full immediately prior to the Effective Date,  The value of the
Stock Options and Plan Options to be assumed by SDRC is estimated to be
approximately $2,6000,000.  The aggregate value of the consideration paid
to CAMAX shareholders and CAMAX option holders is approximately
$32,6000,000.

In arriving at our opinion, we have, among other things:  (i) reviewed and
analyzed the financial terms of the Agreement and various related documents,
(ii) reviewed and analyzed certain historical and projected financial
statements of CAMAX provided by CAMAX's management, (iii) analyzed and
reviewed certain historical and projected financial statements provided by
SDRC's management, (iv) reviewed and analyzed certain historical business
and financial information relating to both CAMAX and SDRC, (v) conducted
discussions with members of the senior management of CAMAX and SDRC with
respect to the business prospects of CAMAX and SDRC, and (vi) reviewed and
analyzed certain other information related to the Merger.  We have also
considered recent merger and acquisition transactions involving similar
companies and have analyzed certain publicly available information,
including financial information relating to public companies whose
operations we deemed comparable to those of CAMAX.  In addition, we have
conducted such other analyses and examinations and considered such other
analyses and examinations and considered such other financial, economic and
market criteria as we have deemed necessary in arriving at our opinion.

In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of the financial, legal, tax, operating and other information
provided to us by the Company and SDRC which we have not independently
verified.  Further, our opinion is based on the assumption that the Merger
will be accounted for as a pooling of interests business combination.  We
have not performed an independent evaluation or appraisal of any of the
respective assets or liabilities of the Company or SDRC and we have not been
furnished with any such appraisals.  With respect to the financial
forecasts, we have assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of the Company and SDRC, as the case may be, as to the respective
future financial performance of the Company and SDRC.

It is understood that this letter is for the information of the Board of
Directors of the Company only, and this letter shall not be published or
otherwise used and no public references to Wessels, Arnold and Henderson
shall be made without our prior consent which consent shall not be
unreasonably withheld.  Further, our opinion speaks only as of the date
hereof and is based on conditions as they exist and information which we
have been supplied as of the date hereof.

Based upon our experience as investment bankers and subject to the
foregoing, including the various assumptions and limitations set forth
herein, it is our opinion that as of the date hereof, the Total Value
offered in the Merger is fair to the shareholders of the Company from a
financial point of view.

Very truly yours,

WESSELS, ARNOLD and HENDERSON, L.L.C.

the articles of an issuing public corporation that provides that section
302A.671 does not apply to a control share acquisition does not give rise
to the right to obtain payment under this section;

 (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,

dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of
this section and section 302A.473, if the beneficial owner submits to the

upon, the notice of the meeting shall inform each shareholder of the right
to dissent and shall include a copy of section 302A.471 and this section and

shareholder and must not vote the shares in favor of the proposed action.

Subd. 4. Notice of procedure; deposit of shares.  (a)  After the proposed
action has been approved by the board and, if necessary, the shareholders,
the corporation shall send to all shareholders who have complied with
subdivision 3 and to all shareholders entitled to dissent if no shareholder
vote was required, a notice that contains:

  (1) The address to which a demand for payment and certificates or
certificated shares must be sent in order to obtain payment and the date by
which they must be received;

  (2) Any restrictions on transfer of uncertificated shares that will apply
after the demand for payment is received;

  (3) A form to be used to certify the date on which the shareholder, or the
beneficial owner on whose behalf the shareholder dissents, acquired the
shares or an interest in them and to demand payment; and

   (4) A copy of section 302A.471 and this section and a brief description
of the procedures to be followed under these sections.

     (b) In order to receive the fair value of the shares, a dissenting

after the notice was given, but the dissenter retains all other rights of
a shareholder until the proposed action takes effect.

  Subd. 5. Payment; return of shares.  (a)  After the corporate action takes
effect, or after the corporation receives a valid demand for payment,
whichever is later, the corporation shall remit to each dissenting
shareholder who has complied with subdivisions 3 and 4 the amount the
corporation estimates to be the fair value of the shares, plus interest,

dissenter the materials described in paragraph (a), a statement of the
reason for withholding the remittance, and an offer to pay to the dissenter
the amount listed in the materials if the dissenter agrees to accept that
amount in full satisfaction.

 The dissenter may decline the offer and demand payment under subdivision
6.  Failure to do so entitles the dissenter only to the amount offered.  If
the dissenter makes demand, subdivisions 7 and 8 apply.

  (c) If the corporation fails to remit payment within 60 days of the
deposit of certificates or the imposition of transfer restrictions on
uncertificated shares, it shall return all deposited certificates and cancel
all transfer restrictions.  However, the corporation may again give notice
under subdivision 4 and require deposit or restrict transfer at a later
time.

   Subd. 6. Supplemental payment;  demand.  If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the
shares plus interest, the dissenter may give written notice to the
corporation of the dissenter's own estimate of the fair value of the shares,
plus interest, within 30 days after the corporation mails the remittance
under subdivision 5, and demand payment of the difference.  Otherwise, a
dissenter is entitled only to the amount remitted by the corporation.

   Subd. 7. Petition; determination.  If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand,
either pay to the dissenter the amount demanded or agreed to by the
dissenter after discussion with the corporation or file in court a petition
requesting that the court determine the fair value of the shares, plus
interest.  The petition shall be filed in the county in which the registered
office of the corporation is located, except that a surviving foreign
corporation that receives a demand relating to the shares of a constituent
domestic corporation shall file the petition in the county in this state in
which the last registered office of the constituent corporation was located. 
The petition shall name as parties all dissenters who have demanded payment
under subdivision 6 and who have not reached agreement with the corporation. 
The corporation shall, after filing the petition, serve all parties with a
summons and copy of the petition under the rules of civil procedure. 
Nonresidents of this state may be served by registered or certified mail or
by publication as provided by law.  Except as otherwise provided, the rules
of civil procedure apply to this proceeding.  The jurisdiction of the court
is plenary and exclusive.  The court may appoint appraisers, with powers and
authorities the court deems proper, to receive evidence on and recommend the
amount of the fair value of the shares.  The court shall determine whether
the shareholder or shareholders in question have fully complied with the
requirements of this section, and shall determine the fair value of the
shares, taking into account any and all factors the court finds relevant,
computed by any method or combination of methods that the court, in its
discretion, sees fit to use, whether or not used by the corporation or by
a dissenter.  The fair value of the shares as determined by the court is
binding on all shareholders, wherever located.  A dissenter is entitled to
judgment in cash for the amount by which the fair value of the shares as
determined by the court, plus interest, exceeds the amount, if any, remitted
under subdivision 5, but shall not be liable to the corporation for the
amount, if any, by which the amount, if any, remitted to the dissenter under
subdivision 5 exceeds the fair value of the shares as determined by the
court, plus interest.

   Subd. 8. Costs; fees; expenses.  (a)  The court shall determine the costs
and expenses of a proceeding under subdivision 7, including the reasonable
expenses and compensation of any appraisers appointed by the court, and
shall assess those costs and expenses against the corporation, except that
the court may assess part or all of those costs and expenses against a
dissenter whose action in demanding payment under subdivision 6 is found to
be arbitrary, vexatious, or not in good faith.

   (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses
of any experts or attorneys as the court deems equitable.  These fees and
expenses may also be assessed against a person who has acted arbitrarily,
vexatiously, or not in good faith in bringing the proceeding, and may be
awarded to a party injured by those actions.

 (c) The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if
any.  (Last amended by Ch. 17, L. '93, eff 8-1-93.)

                             ESCROW AGREEMENT

This Agreement, dated _______, 1996, is made by and among CAMAX
Manufacturing Technologies, Inc., a Minnesota corporation ("CAMAX"),
Structural Dynamics Research Corporation, an Ohio corporation ("SDRC"),
Terrence W. Glarner and Raymond A. Lipkin, acting solely in their capacities
as Representatives (the "Representatives") and First Trust National
Association, a national banking association, as escrow agent (the "Escrow
Agent").

                               INTRODUCTION

A. SDRC, SDRC Systems, Inc., an Ohio corporation ("Surviving Corporation"),
and CAMAX are parties to an Agreement and Plan of Merger dated January
_____, 1996 (the "Agreement") under the terms of which CAMAX will merge with
Surviving Corporation (the "Merger") and all outstanding shares of CAMAX
Common Stock will be converted into a certain number of shares of Common
Stock, without par value, of SDRC ("SDRC Common Stock").  The Agreement
provides for the execution and delivery at the Effective Date thereunder of
an escrow agreement and the delivery of the Retention Shares to the Escrow
Agent for the purpose of establishing an escrow fund (the "Escrow Fund"). 
SDRC and CAMAX have agreed that the execution and delivery of this Escrow
Agreement and the establishment of the Escrow Fund provided for herein shall
satisfy the obligations of the parties to execute and deliver such escrow
agreement.  As hereafter provided, the Escrow Fund hereunder shall fund and
be the sole source of securing the indemnification rights contemplated by
Section 10 of the Agreement (the "Escrow Fund Indemnities").  All
capitalized terms used herein and not otherwise defined shall have the
meanings ascribed to them in the Agreement.

B. The Agreement also provides for the appointment of the Representatives
to act for and on behalf of CAMAX shareholders following the Merger.  The
appointment of the Representatives has been duly approved by the CAMAX
shareholders, and the Representatives have been duly authorized to respond
to the assertion of any and all claims for indemnification by SDRC pursuant
to the terms of this Escrow Agreement and the provisions of the Agreement
pertaining thereto and to act for and on behalf of the CAMAX shareholders
with respect to this Escrow Agreement.

C.  Subsequent to the Effective Date, the Escrow Fund shall be viewed as
owned by the former shareholders of CAMAX and it shall be maintained and
operated in a manner consistent with such ownership.  The Escrow Agent will
administer the Escrow Fund as owned by CAMAX shareholders.

D.  Pursuant to the Agreement, SDRC and CAMAX have agreed that SDRC shall
transfer to the Escrow Agent shares of SDRC Common Stock to be deposited at
the Effective Date in escrow with the Escrow Agent and held in accordance
with the terms of this Escrow Agreement (the "Retention Shares"). 
Accordingly, in consideration of consummating the transactions contemplated
by the Agreement, the covenants and agreements herein set forth, and for
other valuable consideration the receipt of which is hereby acknowledged the
parties further agree as follows:

1. Appointment and Agreement of Escrow Agent.  SDRC, CAMAX and the
Representatives, on behalf of the CAMAX shareholders, hereby appoint First
Trust National Association, as, and First Trust National Association agrees

Minnesota, by the Escrow Agent at 180 E. Fifth Street, St. Paul, Minnesota
55101.

2. Agreement Not Limited by this Escrow Agreement.  This Escrow Agreement
and the deposit of the Retention Shares are without prejudice to and are not
in limitation of, any obligations of CAMAX or the CAMAX shareholders to SDRC
in respect of any of the covenants, representations or warranties of CAMAX,
contained in the Agreement, except insofar as the indemnity obligations of
Section 10 are to be satisfied solely from the Escrow Fund.

3. Establishment of Escrow.

   3.1 Delivery of Property.

      (a)  Simultaneously with the execution of this Escrow Agreement, SDRC,
CAMAX and the Representatives, on behalf of the CAMAX shareholders, have

     (b)  Together with the certificates representing the Retention Shares
transferred to the Escrow Agent, the Representatives have delivered to the
Escrow Agent duly executed stock powers (endorsed in blank) with respect
thereto with signatures guaranteed by a bank or trust company or by a member
firm of the New York Stock Exchange, together with a list of CAMAX
shareholders, including their tax I.D. numbers and addresses.

       (c) The Escrow Fund shall be held and used only for the purposes of
funding the indemnity obligations set forth in Article 10 of the Agreement.

   3.2  Receipt.  The Escrow Agent hereby acknowledges receipt of the
Retention Shares and agrees to hold and disburse the Retention Shares in
accordance with the terms and conditions of this Escrow Agreement and the
Agreement for the uses and purposes stated herein and therein.

   3.3  Voting Rights of Escrowed Shares.  All voting rights with respect
to Retention Shares shall be exercised by CAMAX shareholders in accordance
with their proportionate interests therein, and the Escrow Agent shall from
time to time execute and deliver to CAMAX shareholders such proxies,
consents or other documents as may be necessary to enable the respective
CAMAX shareholders to exercise such rights.

    3.4  Cash Dividends.  Pending the disbursement of the Retention Shares
pursuant to this Escrow Agreement, the Escrow Agent shall hold the
certificates representing the Retention Shares in the Escrow Fund.  All cash
dividends received with respect to Retention Shares shall be income for tax
purposes to CAMAX shareholders and shall be distributed currently by the
Escrow Agent to CAMAX shareholders in accordance with their proportionate
interests in the Retention Shares.

   3.5  Stock Splits/Stock Dividends.  In case SDRC shall at any time
hereafter subdivide or combine the outstanding shares of the SDRC Common
Stock or declare a dividend payable in SDRC Common Stock, the number of
Retention Shares immediately prior to the subdivision, combination or record
date for such dividend payable in common stock shall forthwith be
proportionately increased, in the case of combination, or decreased, in the
case of subdivision, or dividend payable in SDRC Common Stock.

4.  Liabilities etc. Covered.  This Escrow Agreement has been executed and
the deposit of the Retention Shares hereunder has been made pursuant to
Section 2.2 and Article 10 of the Agreement.  The deposit of the  Retention
Shares in the Escrow Fund has been made for the purpose of funding and
securing, to the extent of the Retention Shares, the Escrow Fund Indemnities
until the expiration of the Retention Period.

5. Procedures for Disbursement of the Escrow Fund to SDRC.

   5.1 Disbursement of the Escrow Fund.  Whenever there shall be delivered
to the Escrow Agent (a) a certificate signed by SDRC and the 
Representatives certifying, or (b) a certified copy of a final, non-app-
ealable judgment of a court of competent jurisdiction determining, that an
amount is due to SDRC pursuant to Article 10 of the Agreement and further
specifying the number of shares of SDRC Common Stock, valued as provided in
Section 2.2 of the Agreement, to be transferred hereunder,  the Escrow Agent
shall, to the extent that the amount of Retention Shares then held by it in
the Escrow Fund shall be sufficient for such purpose, promptly (and in no
event later than five business days following receipt of either document
referred to in clauses (a) and (b) of this Section 5.1) cause certificates
representing such number of Retention Shares, and duly executed stock powers
with respect to such certificates, with signatures guaranteed by a bank or
trust company or by a member firm of the New York Stock Exchange, to be
delivered to SDRC.

    5.2 No Fractional Shares.  In the event of any disbursement of Retention
Shares pursuant to subparagraph 5.1, no fractional shares shall be
delivered, but rather the Escrow Agent shall adjust the amount of Retention
Shares to be delivered to SDRC by rounding to the nearest whole share.

6. Expiration of Retention Period.

     (a) On the business day next following the expiration of the Retention
Period, SDRC shall authorize the Escrow Agent to deliver to the
Representatives, on behalf of the CAMAX shareholders, the Retention Shares
then held hereunder in the Escrow Fund, provided however, that there shall
be deducted from the amount to be delivered to the Representatives the
Escrowed Fund Reserved Amount (as defined in Section 7 hereof).

      (b) This Escrow Agreement shall automatically terminate if and when
all the Retention  Shares shall have been distributed by the Escrow Agent
in accordance with the terms of this Escrow Agreement.

7.  Retention of Retention Shares Following the Expiration of the Retention
Period.  In the event that at the expiration of the Retention Period claims
for indemnification shall have been made pursuant to Article 10 of the
Agreement, then SDRC may in good faith, at any time, prior to the expiration
of the Retention Period notify the Escrow Agent to such effect in writing,
which written notice shall describe briefly the nature of each such claim,
the facts and circumstances which give rise to each such claim, and the
estimated amount, based on the good faith judgment of SDRC as determined
solely by SDRC, of the potential liability, with respect to each such claim,
and the provisions of the Agreement or this Escrow Agreement on which each
such claim is based.  SDRC shall promptly deliver to the Representatives a
copy of such written notice.  The Escrow Agent shall have no obligation to
verify that delivery of such notice has been made by SDRC to the
Representatives, but agrees to forward to the Representatives, promptly, by
overnight mail, a copy of the notice, received by it.  Certificates
evidencing Retention Shares having a value (based upon the Applicable Value
Per Share of SDRC Common Stock) equal to one hundred fifty percent (150%)
of the total of the amounts set forth in such written notice with respect
to the claim or claims described therein shall be set aside and retained (to
the extent available in the then remaining Retention Shares) by the Escrow
Agent as a reserve to cover such claim or claims (such certificates so set
aside and reserved, as reduced from time to time pursuant to the provisions
of this Paragraph 7 or of Paragraph 5.1 hereof, being herein called the
"Escrow Fund Reserved Amount").

8.  No Transfer of Retention Shares.  While any Retention Shares shall
continue to be held by the Escrow Agent, neither the CAMAX shareholders nor
the  Representatives will transfer, sell, pledge, create a security interest
in or otherwise dispose of their rights to any of the Retention Shares, or
distributions with respect thereto.

9.  The Escrow Agent.

    9.1 Indemnification of the Escrow Agent.  SDRC and the  Representatives,
on behalf of the CAMAX shareholders, jointly and severally agree to
indemnify and hold the Escrow Agent and its directors, officers and
employees harmless from and against any and all costs, charges, damages, and
attorneys' fees which the Escrow Agent in good faith may incur or suffer in
connection with or arising out of this Escrow Agreement.

    9.2 Duties of The Escrow Agent.  The Escrow Agent shall have no duties
other than those expressly imposed on it herein and shall not be liable for
any act or omission except for its own negligence or willful misconduct.

    9.3 Fees of the Escrow Agent.  The fees and charges of the Escrow Agent
(including its attorneys fees and expenses) with respect to this Escrow
Agreement shall be paid equally by the CAMAX shareholders and SDRC in
accordance with the Escrow Agent's customary fees as charged from time to
time.  The Representatives, on behalf of the CAMAX shareholders, agree that
the Escrow Agent may deduct any unpaid fees due from the CAMAX shareholders
from the Retention Shares prior to the Escrow  Agent's distributing any
assets in connection with the termination of the Escrow Fund.

    9.4 Escrow Agent to Follow Instructions of SDRC and the Representatives.
 Any provision herein to the contrary notwithstanding, the Escrow Agent
shall at any time and from time to time take such action hereunder with
respect to the Retention Shares as shall be agreed to in writing by SDRC and
the  Representatives, provided that the Escrow Agent shall first be
indemnified to its satisfaction jointly and severally, by SDRC and the CAMAX
shareholders upon the dissolution of CAMAX with respect to any of its costs
or expenses which might be involved.

   9.5 Resignation of the Escrow Agent.  The Escrow Agent may resign at any
time by providing SDRC and the Representatives with thirty (30) days'
written notice of its intention to do so, provided that a successor Escrow
Agent has been appointed.  The Escrow Agent's resignation shall be effective
upon delivery of the Retention Shares to the successor Escrow Agent and the
successor assuming the obligations, rights and duties of the Escrow Agent
hereunder.

10.  Other Provisions.

     10.1 Security Interest.

           (a) The  Representatives, on behalf of the CAMAX shareholders,
hereby grant to SDRC a first priority perfected security interest in the
Retention Shares to secure SDRC's rights to indemnification under the
Agreement and SDRC's rights under this Escrow Agreement.  The Escrow
Agreement shall constitute a security agreement under applicable law.

           (b) The parties agree that this security interest shall attach
as of the execution of this Escrow Agreement.  The parties agree that, for
the purpose of perfecting SDRC's security interest in the above designated
Retention Shares held by the Escrow Agent pursuant to this Escrow Agreement,
SDRC designates the Escrow Agent to acquire and maintain possession of the
Retention Shares and act as bailee for SDRC with notice of SDRC's security
interest in said property under the Uniform Commercial Code and that
possession of the Retention Shares by the Escrow Agent acknowledges that it
holds the Retention Shares for SDRC for purposes of perfecting the security
interest.  The Representatives and the Escrow Agent shall take all other
actions requested by SDRC to maintain the perfection and priority of the
security interest in the Retention Shares.

         (c) SDRC shall release the security interest herein granted and the
security interest shall be terminated to the extent of any disbursement of
Retention Shares hereunder by the Escrow Agent in accordance with the terms
of this Escrow Agreement.  Upon final disbursement of any Retention Shares
to the  Representatives, SDRC shall do all acts and things reasonably
necessary to release and extinguish such security interest.  The
Representatives, on behalf of CAMAX shareholders, and SDRC hereby
specifically agrees and acknowledges that the grant of this security
interest pursuant to this Section 10.1 shall not in any way modify either
the procedures the Representatives, CAMAX shareholders and/or SDRC must
follow in order to obtain possession of any of the Retention Shares from
those procedures and rights expressly provided for in this Escrow Agreement
or in the Agreement.

  10.2 Notices.  All notices and other communications hereunder shall be in
writing and shall be sufficiently given if made by hand delivery, by telex,
by telecopier, or by registered or certified mail (postage prepaid and
return receipt requested) to the parties at the following addresses (or at
such other address for a party as shall be specified by it by like notice)
provided that communications given to the Escrow Agent shall be considered
given when received by the Escrow Agent and, provided further, that any
communications to the Escrow Agent directing it to make a disbursement from
the Escrow Fund will be made by the Escrow Agent only upon receipt of
originally executed copies of such communication.

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers

Section 1701.13 of the Ohio Revised Code provides that a corporation may
indemnify or agree 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 an 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, trustee, officer, employee, or agent of another
corporation, domestic or foreign, nonprofit or for profit, 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 termination of any action, suit or
proceeding by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act 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 that he
had reasonable cause to believe that his conduct was unlawful. 
Section 1701.13 further specifies that a corporation may indemnify or agree
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, trustee, officer, employee, or agent of another corporation,
domestic or foreign, nonprofit or for profit, 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 of common pleas,
or the court in which such action or suit was brought, determines 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 as the court of common pleas or such other
court shall deem proper.  In addition, Section 1701.13 requires a
corporation to pay any expenses, including attorneys' fees, of a director
in defending an action, suit or proceeding referred to above as they are
incurred, in advance of the final disposition of the action, suit or
proceeding, upon receipt of an undertaking by or on behalf of the director
in which he agrees to both  (i) repay such amount if it is proved by clear
and convincing evidence that his action or failure to act involved an action
or omission undertaken with deliberate intent to cause injury to the
corporation or undertaken with reckless disregard for the best interests of
the corporation and  (ii) reasonably cooperate with the corporation
concerning the action, suit or proceeding.  The indemnification provided by
Section 1701.13 shall not be deemed exclusive of any other rights to which
those seeking indemnification may be entitled under the Articles of
Incorporation or Code of Regulations of SDRC.

The Code of Regulations of SDRC provides that SDRC shall indemnify each
director and each officer of SDRC, and each person employed by SDRC who
serves at the written request of the President of SDRC as a director,
trustee, officer, employee or agent of another corporation, domestic or
foreign, nonprofit or for profit, to the full extent permitted by Ohio law. 
SDRC may indemnify assistant officers, employees and others by action of the
Board of Directors to the extent permitted by Ohio law.

SDRC carries directors' and officers' liability insurance coverage which
insures its directors and officers and the directors and officers of its
subsidiaries in certain circumstances.

Item 22. Undertakings

(1)   The undersigned registrant hereby undertakes to file during any period
in which offers or sales are being made, a post-effective amendment to this
registration statement:  (i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;  (ii) to reflect in the prospectus
any facts or events arising after the effective date of the registration
statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the
information set forth in the registration statement, and  (iii) to include
any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change
to such information in the registration statement.  The registrant also
undertakes:  (i) that for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof, and  (ii) to remove from
registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.

(2)   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.

(3)   The undersigned registrant hereby undertakes as follows:  that prior
to any public reoffering of the securities registered hereunder through use
of a prospectus which is 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.

(4)   The registrant undertakes that every prospectus  (i) that is filed
pursuant to paragraph (2) immediately preceding, 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 an 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 offering therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

(5)   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 foregoing provisions,
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 of 1933 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 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 whether such
indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of
such issue.

(6)   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.

(7)   The undersigned registrant hereby undertakes to deliver or cause to
be delivered with the prospectus, to each person to whom the prospectus is
sent or given, the latest annual report to security holders that is
incorporated by reference in the prospectus and furnished pursuant to and
meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities
Exchange Act of 1934; and, where interim financial information required to
be presented by Article 3 of Regulation S-X are not set forth in the
prospectus, to deliver or cause to be delivered to each person to whom the
prospectus is sent or given, the latest quarterly report that is
specifically incorporated by reference in the prospectus to provide such
interim financial information.

(8)   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
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.

Ladies and Gentlemen:

This opinion is rendered for use in connection with the Registration
Statement on Form S-4, prescribed pursuant to the Securities Act of 1933,
to be filed by Structural Dynamics Research Corporation (the "Company") with
the Securities and Exchange Commission on February 12, 1996, under which up
to 2,000,000 shares of the Company's Common Stock without par value ("Common
Stock") are to be registered.

We hereby consent to the filing of this opinion as Exhibit 5 and 23.4 to the
Registration Statement and to the reference to our name in the Registration
Statement.

As counsel to the Company, we have examined and are familiar with originals
or copies, certified or otherwise identified to our satisfaction, of such
statutes, documents, corporate records, certificates of public officials,
and other instruments as we have deemed necessary for the purpose of this
opinion, including the Company's Amended Articles of Incorporated and
Amended Code of Regulations and the record of proceedings of the
shareholders and directors of the Company.

Based upon the foregoing, we are of the opinion that:

1. The Company has been duly incorporated and is validly existing and in
good standing as the corporation under the laws of the State of Ohio.

2. When the Registration Statement shall have been declared effective by
order of the Securities and Exchange Commission and up to 2,000,000 shares
of the Common Stock to be issued for sale to the public shall have been
issued and sold upon the terms set forth in the Registration Statement, such
shares will be legally and validly issued and outstanding, fully-paid and
nonassessable.

Very truly yours,

THE FOLLOWING OPINION IS INTENDED TO BE RENDERED UPON THE CLOSING OF THE
TRANSACTION DESCRIBED THEREIN IN SUBSTANTIALLY THE FORM PRESENTED, ASSUMING
NO CHANGES IN THE FACTS OR THE LAW UPON WHICH SUCH OPINION IS BASED, AND
SUBJECT TO RECEIPT, REVIEW AND APPROVAL OF FINAL DOCUMENTS



Structural Dynamics Research Corporation
2000 Eastman Drive
Milford, Ohio 45150

CAMAX Manufacturing Technologies, Inc.
7851 Metro Parkway
Minneapolis, Minnesota 55425

Dear Sirs:

As counsel for Structural Dynamics Research Corporation, ("SDRC"), we have
been requested to render our opinion with respect to certain Federal income
tax consequences of the Agreement of Merger and Plan of Reorganization dated
January 16, 1996, among SDRC, CAMAX Manufacturing Technologies, Inc.
("CAMAX") and SDRC Systems, Inc. providing for the merger of CAMAX into SDRC
Systems, Inc.

We have reviewed the terms of the proposed transaction as set forth in the
Agreement of Merger and Plan of Reorganization and have received
representations from certain executive officers of SDRC and CAMAX and
certain CAMAX shareholders, relating to various factual matters relevant to
the opinions expressed herein.  Our opinion is based on the Agreement of
Merger and Plan of Reorganization, the facts set forth in such
representations and on our analysis of the applicable provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations, Internal Revenue Service Rulings, and judicial decisions
interpreting the Code as in effect on the date hereof, all of which are
subject to change, prospectively or retroactively.  We have not
independently verified the factual matters set forth in the representations.

Based upon and subject to the foregoing, our opinion is as follows:

1.  The merger of CAMAX with and into SDRC Systems, Inc. will constitute a
reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D)
of the Code and, for purposes thereof, SDRC, SDRC Systems, Inc. and CAMAX
each will qualify as a "party to a reorganization" within the meaning of
Section 368(b) of the Code;

2.  No gain or loss will be recognized by CAMAX as a consequence of the
merger;

3.  No gain or loss will be recognized by SDRC Systems, Inc. on the receipt
by SDRC Systems, Inc. of substantially all the assets of CAMAX and the
assumption by SDRC Systems, Inc. of CAMAX's liabilities;

4.  No gain or loss will be recognized by the shareholders of CAMAX who
receive solely SDRC common stock in exchange for shares of CAMAX common
stock pursuant to the Agreement of Merger (disregarding for this purpose any
cash received for fractional share interests to which they may be entitled);

5.  The federal income tax basis of the SDRC common stock to be received by
CAMAX shareholders who exchange their shares of CAMAX common stock solely
for shares of SDRC common stock (disregarding for this purpose any cash
received for fractional share interests to which they may be entitled) will
be, in each instance, the same as the federal income tax basis of the CAMAX
common stock surrendered in exchange therefor;

6.  The holding period of the SDRC common stock received by a CAMAX
shareholder will include, in each case, the period during which the CAMAX
common stock surrendered in exchange therefor was held, provided that the
CAMAX common stock was held as a capital asset by such shareholder on the
date of the exchange; and

7.  Holders of CAMAX common stock who receive cash in lieu of fractional
shares of SDRC common stock will be treated as having received such
fractional share of SDRC common stock and then as having received such cash
in redemption of such fractional share subject to the provisions of Section
302 of the Code.

Our opinion is limited to the matters expressly addressed above.  No opinion
is given or should be inferred as to any other issue.

We consent to the filing of this form of opinion as an exhibit to the
Registration Statement filed in connection with the merger.

Very truly yours,

DINSMORE & SHOHL

Management's Discussion and Analysis of Financial Condition and
Results of Operations 
Structural Dynamics Research Corporation


(in thousands)

The Company operates in two segments: software products and
services, and engineering services.  Revenue in the software
products and services segment consists primarily of revenue from
software licenses, software maintenance contracts and customer
training.  Revenue in the engineering services segment consists of
consulting activities which are undertaken on either a time and
materials or a fixed fee contract basis.


Software Products and Services

The software products and services segment accounted for
approximately 89%, 86% and  85% of SDRC's consolidated revenue for
the years ended December 31, 1994, 1993 and 1992, respectively, and
approximately (108)%, (103)% and 99%  of consolidated operating
income (loss) for the same periods.

Software segment revenue in 1994 increased $20,977 or 16% over
1993. This growth comparison excludes $8,485 of revenue generated
by the SDRC Software and Services GmbH joint venture established in
the first quarter of 1994 and accounted for under the equity
method.  Maintenance revenue derived from annual software
maintenance contracts increased 10% primarily due to license
increases in prior years. Revenue was negatively impacted by a 25%
decline from an OEM customer, whose software marketing agreement
was terminated in December 1994.  Additionally, revenue was
impacted by difficult market conditions in Europe. Software segment
revenue outside of North America accounted for 62%, 63% and 69% of
software revenue in 1994, 1993 and 1992, respectively. The Company
expects the international market to continue to account for a
significant portion of total software segment revenue.

The software segment incurred operating losses of $2,247 in 1994
and $8,657 in 1993.  This improvement was due primarily to
increased revenues partially offset by increased expenses.    

Software segment revenue in 1993 was level with 1992. Management's
expectation was that 1993 revenue would increase more than the
performance ultimately achieved.  The license revenue in 1993
suffered in part from technical problems associated with the I-DEAS
Master Series initial product release in June 1993.  As a result of
the technical problems, a number of customers deferred large
purchase decisions until completion of their benchmark testing of
the   I-DEAS Master Series software after the Company had addressed
the unforeseen problems.  Additionally, revenue was impacted by
difficult economic conditions in Europe and Japan and by a 42%
decline from an OEM customer.  Maintenance revenue derived from
annual software maintenance contracts increased 9% primarily due to
license increases in prior years. 

The software segment incurred an operating loss of $8,657 in 1993
compared to operating income of $12,084 in 1992 resulting from
significant increases in cost of revenue and selling, general and
administrative expenses as described below.


Engineering Services

In 1994, 1993 and 1992, the engineering services segment
represented 11%, 14% and 15%, respectively, of the Company's
consolidated revenue and 8%, 3% and 1% of consolidated operating
income (loss) for the same periods.
 
In 1994, 1993 and 1992, the engineering services segment revenue
decreased 5%, 11% and 15%,  respectively.  The revenue reduction
was due to downsizing portions of the consulting business not
considered synergistic with the software segment.  The Company has
continued to align the engineering services cost structure with the
anticipated revenue stream.


Cost and Expenses

Cost of Revenue.  Cost of revenue consists principally of the
amortization of capitalized software construction costs, external
commissions associated with indirect marketing channels and the
cost of distributing software products and providing engineering
consulting services.  Cost of revenue includes $7,137, $9,539 and
$3,667 for amortization of software construction costs in 1994,
1993 and 1992, respectively.

Cost of revenue for 1994 decreased 6% from 1993 primarily due to
the charge in 1993 of approximately $3,311 relating to software
construction costs determined to be non-recoverable upon the
release of the I-DEAS Master Series product.  Engineering services
consulting costs also declined 5% which is consistent with the
decline in engineering services revenue. These reductions are
partially offset by  a full year of amortization of software
construction costs for the I-DEAS Master Series product which was
initially released in June 1993 and an increase in the software
segment's variable costs directly associated with the product
licensing and distribution.

Cost of revenue in 1993 increased 13% over 1992 due to the
commencement of amortization of software construction costs for the
I-DEAS Master Series product upon its initial release in June 1993,
and approximately $3,311 relating to software construction costs
determined to be non-recoverable upon the release of the I-DEAS
Master Series product.  In addition, variable costs directly
associated with software product licensing and distribution
increased.

Research and Development Expenses.  Research and development
expenses consist primarily of expenses for development of software
products.  These expenses cannot be capitalized in accordance with
Statement of Financial Accounting Standards (SFAS) No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased,
or Otherwise Marketed".  Research and development expenses exclude
capitalized software development costs of  $9,312, $11,282 and 
$9,365 in 1994, 1993 and 1992, respectively.

Research and development expenses amounted to $33,560, $25,937 and
$25,369 in 1994, 1993 and 1992, respectively. During 1994, research
and development expenses increased significantly in line with the
Company's commitment to the technological advancement of its
product line.   Specifically, the product development staff focused
on modifications to I-DEAS Master Series 1.0 and early product
development activities associated with I-DEAS Master Series 3.0.

Royalty fees paid to third parties under licensing agreements,
another component of research and development expenses, increased
significantly in each of the last three years.  Third party royalty
expenses increased 53% in 1994 over 1993 primarily due to fees
associated with product data management (PDM) software developed by
a joint venture investee.

Selling, General and Administrative Expenses.  Selling, general and
administrative expenses consist principally of costs incurred in
the software products and services segment and corporate staff. 
Selling, general and administrative expenses increased 9%, 18% and
26% in 1994, 1993 and 1992, respectively.

During 1994 and 1993, the Company incurred significant expenses
from increased headcount in the sales and technical support
organizations to promote direct sales and support new and existing
customers.  The primary focus was to assist the Company's customers
in their transitioning efforts to the I-DEAS Master Series product
introduced in June 1993.  The Company anticipated higher revenue
growth to offset the incremental headcount costs from sales and
support activities.

In the fourth quarter of 1994, the Company initiated a plan to cut
costs and strengthen its competitive position by reducing its
workforce by 87 people.  These employees were primarily product
development, marketing and administrative personnel.  As a result,
the Company recognized a charge of $1,247 for severance costs and
outplacement assistance for employees.   In 1994, the Company paid
$303 to these employees.   At December 31, 1994, the Company had
accrued severance benefits of $944 related to this matter.  In
February, 1995, the Company further reduced its workforce and will
record a related charge to income of approximately $1,000. 

Additionally, in 1994, the Company incurred severance costs of
$1,919 due to the termination of its former Chief Financial Officer
and the other managers and the resignation of its former Chief
Executive Officer. The former Chief Executive Officer was employed
pursuant to an employment agreement with the Company which provided
for specified severance benefits.

In 1993, the Company recognized expense of $4,200 for the
settlement of a claim by a significant OEM customer.  Certain
discretionary employee benefits were reduced in 1993 to offset the
lower than expected revenue growth as a result of technical issues
associated with the initial introduction of I-DEAS Master Series.



Equity in Losses of Affiliates

During 1992, the Company formed a joint venture with Control Data
Systems, Inc., Metaphase Technology, Inc.  Metaphase is involved in
developing and marketing product data management software.  During
1994, the Company formed a joint venture with Siemens Nixdorf
Informationssysteme AG, SDRC Software and Services, GmbH (SDRC
GmbH) to market the Company's software products in Central Europe. 
The Company's equity in the losses of affiliates represents its
share of Metaphase and SDRC GmbH losses, the majority of which
resulted from the SDRC GmbH joint venture.


Other Income

Other income consists principally of interest income.  Increasing
interest rates in 1994 resulted in higher interest income. In 1994
the Company also received interest on an income tax refund.


Income Taxes

During 1994 and 1993, the Company recorded tax expense of $3,833
and $4,376 on pretax losses of $5,168 and $7,356, respectively. 
Although the Company incurred losses in 1994 and 1993, there were
provisions for income taxes in both years consisting primarily of
income taxes currently payable to foreign jurisdictions and foreign
withholding taxes incurred on the Company's software licensing
revenue.  These withholding taxes can be credited against the
Company's U.S. income tax liability.   Due to U.S. tax net
operating losses (NOLs), the Company is not currently in a position
to utilize these foreign tax credits (FTCs).   The FTCs and NOLs
are available to offset future U.S. income tax liabilities, subject
to various restrictions.  No tax benefit was currently recognized
for these FTCs and NOLs as their realization is not assured. 

Effective January 1, 1992, the Company adopted SFAS No. 109,
"Accounting for Income Taxes".  The cumulative effect (for periods
prior to January 1, 1992) of applying this statement was to
increase net income by $700 or $.02 per share for the year ended
December 31, 1992.

In 1994, the Company received a tax refund of $1,754 for research
and experimentation credits  not previously recorded.


Postemployment Benefits

Effective January 1, 1994, the Company adopted the provisions of
SFAS No. 112, "Employers' Accounting for Postemployment Benefits". 
This statement requires that companies providing postemployment
benefits to their employees accrue the cost of benefits, if
attributable to employees' service already rendered. The Company
provides severance benefits for involuntarily terminated employees.

The cumulative effect of adopting SFAS 112 reduced 1994 income by
$3,896.   The annual incremental charge for future periods is not
anticipated to be material.


Liquidity and Capital Resources

As of December 31, 1994, the Company had $46,240 in cash, cash
equivalents and investments.   The Company's working capital was
$27,590.   As of March 1, 1995, the Company also has an unsecured
bank line of credit of $15,000.

During 1994, 1993 and 1992 the Company generated cash flows from
operations of $6,176, $19,467 and $21,855, respectively.   In 1994,
the sources of net cash provided by operating activities were
significantly reduced by the $16,158 increase in accounts
receivable.   The 1994 growth in accounts receivable over 1993 was
due to the higher level of revenue in the 1994 fourth quarter,
primarily in North American and Far East operations.

The Company had no borrowings in 1994.

The Company's sources of liquidity and funds anticipated to be
generated from operations are expected to be adequate for the
Company's cash requirements in the foreseeable future.  The Company
paid no dividends during the period 1992 through 1994 and intends
to continue its policy of retaining earnings to finance future
growth.  The Company has no current commitments for material
capital expenditures.  See Note 9 to the consolidated financial
statements for additional commitments and contingencies.   The
Company does not expect inflation to have a material impact on its
future operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Structural Dynamics Research Corporation

(in thousands, except per share data)

(1)  Summary of Significant Accounting Policies

(a)  Basis of Consolidation

The consolidated financial statements include the accounts of the
Company and its wholly- owned subsidiaries.  Investments in which
the Company has significant influence, but not control, are
accounted for under the equity method.  All significant
intercompany balances and transactions have been eliminated. 

(b)  Revenue Recognition

The use of software programs is licensed through the Company's
direct sales force and by specific arrangements with certain
hardware vendors and distributors.  Revenue generated from licenses
is recognized when the following criteria have been met: (a) a
written order for the unconditional license of software has been
received, (b) the Company has delivered the products and performed
substantially all services for which it was committed, (c) the
customer is obligated to pay and (d) collectibility is probable.  

Under the terms of a former licensing agreement with an OEM
customer, the Company was unable to determine the amount of revenue
earned until cash was received from the customer.  Amounts recorded
as revenue on the cash basis were $5,877, $7,877 and $13,599 in
1994, 1993 and 1992, respectively.  This licensing agreement was
terminated by the Company in 1994.

Maintenance revenue is recognized ratably over the term of the
agreement and represents the substantial component of deferred
revenue.

The Company recognizes revenue and expenses from engineering
consulting contracts based on the percentage of completion method
of accounting.  When losses are estimated to occur on these
contracts, the entire estimated loss is recognized at that time.

(c)     Earnings (Loss) Per Share

Earnings (loss) per common and common equivalent share is computed
using the weighted average number of common and dilutive common
equivalent shares outstanding during the period. Dilutive common
equivalent shares consist of stock option grants using the treasury
stock method.  

(d)     Cash and Cash Equivalents

The Company considers investments in interest bearing accounts,
certificates of deposit, commercial paper and reverse repurchase
agreements with maturities of less than 90 days to be cash
equivalents.  Reverse repurchase agreements of $11,549 and $19,555
were held at December 31, 1994 and 1993, respectively.   Due to the
short-term nature of the agreements, the Company and the trustee do
not take possession of the securities, which are segregated in the
accounts of the trustee; the Company and the trustee monitor the
underlying market values to assure that sufficient collateral
exists to cover the initial investment and accrued interest.   
(e)     Investments


Effective January 1, 1994, the Company adopted Statement of
Financial Accounting Standards (SFAS) No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" which requires
the Company to distinguish between those securities held for sale
and those for which the ability and intent to hold to maturity
exists.   Unrealized gains and losses on assets held for sale are
included in a separate component of equity.  The effect of adopting
SFAS No. 115 was not material.

The Company invests in marketable securities which are
available-for-sale and are recorded at market value.  The Company
also invests in certificates of deposit which are held-to-maturity
and are recorded at amortized cost which approximates market value.

 Realized and unrealized gains and losses are determined based on
the specific identification method.

(f)     Property and Equipment

Depreciation is primarily computed on the straight-line method. 
Leasehold improvements are amortized on the straight-line method
over the lesser of the life of the lease or the estimated useful
life of the improvement.  The general ranges of years used in
calculating depreciation and amortization are: computer and other
equipment, 2-5 years; office furniture and equipment, 7 years; 
leasehold improvements, 1-10 years.

(g)     Computer Software Construction Costs

The Company designs, develops and markets computer software
products.  Costs related to the construction of software are
capitalized and are amortized over the useful lives of such
software, which are estimated to be no more than five years.
Computer software construction costs are shown net of accumulated
amortization of $11,573 and $4,436 at December 31, 1994 and 1993,
respectively.  As of December 31, 1994 and 1993, computer software
construction costs, net, include only those costs related to
current software products. Amortization is the greater of the
amount computed using (a) the ratio that current gross revenue
bears to the total of current and anticipated future years'
revenue, or (b) the straight-line method over the remaining
estimated economic lives of the software products.  The Company
included in amortization expense approximately $3,311 and $68 for
the years ended December 31, 1993 and 1992, respectively, related
to software construction costs determined to be non-recoverable.

(h)    Foreign Currency Translation and Hedging Contracts

The functional currency of the engineering services foreign
operations is their local currency and their assets and liabilities
are translated at year-end exchange rates.  Translation gains and
losses are not included in determining net income but are
accumulated in a separate component of shareholders' equity.  For
foreign software products and services operations, the U.S. dollar
is the functional currency and foreign currency gains and losses,
which are not material, are included in determining net income.

In 1993 the Company began hedging certain portions of its exposure
to foreign currency fluctuations, primarily the Company's net
assets in foreign subsidiaries, by utilizing forward foreign
exchange contracts.  At December 31, 1994, the Company had
contracts to exchange foreign currencies totaling $16,500 which
matured in January 1995.  Gains and losses associated with these
financial instruments are recorded currently in income to offset
the foreign exchange gains and losses on the assets and liabilities
being hedged.  The interest element of the foreign currency
instruments is recognized over the life of the contract.  Should
the counterparty to these contracts fail to meet its obligations,
the Company would be exposed to foreign currency fluctuations,
along with the cost, if any, to extinguish the contracts.

(i)     Income Taxes

Effective January 1, 1992, the Company adopted SFAS No. 109,
"Accounting for Income Taxes". The cumulative effect of applying
this statement was to increase net income by $700 or $.02 per share
in 1992.  Under SFAS No. 109, deferred tax assets and liabilities
are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of
assets and liabilities and their respective tax bases.  A valuation
allowance is provided against deferred tax assets when the Company
believes it is more likely than not that the deferred tax assets
will not be realized.

The Company does not accrue Federal income taxes on undistributed
earnings of its foreign subsidiaries that have been, or are
intended to be, permanently reinvested.  Undistributed earnings
amounted to approximately $3,705 at December 31, 1994.

(j)     Concentration of Credit Risk

The Company's revenue is generated from customers in diversified
industries, primarily in North America, Europe and the Far East. 
In 1994 and 1993, the Company generated revenue from a significant
customer aggregating 11%.  The Company performs ongoing credit
evaluations of its customers and generally does not require
collateral.  The Company maintains allowances for potential credit
losses which management believes to be adequate in the
circumstances.

The Company invests its excess cash with major financial
institutions with strong credit ratings and, by policy, limits the
amount of credit exposure in any one such institution.

(k)     Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, investments,
accounts receivable, accounts payable, accrued expenses and forward
foreign exchange contracts approximate fair value.

Deferred state and foreign taxes are not material.


(4)   Income Taxes - continued

The provision for income taxes
differs from the amounts computed
by using the statutory  U.S.
Federal income tax rate.  The              Year ended December 31
reasons for the differences
are as follows:                          1994      1993      1992

Computed expected income tax
 expense (benefit)                    $(1,809)   $(2,575)   $4,728

Increase (reduction) resulting
 from:
     Foreign taxes, without current
      benefit                           5,176      3,876       --
     U.S. losses without tax benefit    1,809      2,575       --
     Receipt of research and
      experimentation tax credit refund
          not previously recorded      (1,754)        --       --
     State taxes, net of federal benefit  411        500      646
     Research and experimentation credit   --         --     (354)
     Other, net                            --         --      112
                                       $3,833     $4,376   $5,132

The tax effects of temporary differences
that give rise to the deferred tax assets
and deferred tax liabilities are as
follows:                                   Year ended December 31,
                                            1994            1993
Deferred tax assets:

     Revenue recognition and
     accounts receivable                $      730       $  18,276

     Property and equipment                  1,028             959

     Other liabilities and reserves          2,926             998

     Tax credit and net operating
     loss carryforwards                     24,412           2,661

     Other                                     792             802
          Total deferred tax assets         29,888          23,696

     Valuation allowance                   (19,537)        (14,628)
          Net deferred tax assets           10,351           9,068

Deferred tax liabilities:

     Computer software construction
     costs, net of amortization            (10,351)         (9,068)

          Total net deferred taxes      $       --        $      --

Of the $24,412 in tax credit and net operating loss carryforwards
available at December 31, 1994, $10,908 of foreign tax credits
expire in the years 1997 through 1999, $2,243 of research and
experimentation credits expire in the years 2007 through 2009,
$1,017 of alternative minimum taxes never expire and $10,244 of net
operating losses expire in the year 2009.

The net change in the valuation allowance for deferred tax assets
was an increase of $4,909 in 1994 and $8,533 in 1993.   Of the
$19,537 in valuation allowance at December 31, 1994, $7,908 is
attributable to the tax benefit of stock option exercises.  Such
benefits will be credited to capital in excess of stated value when
realized.


(5)    Postemployment Benefits

In the first quarter of 1994, the Company adopted the provisions of
SFAS No. 112, "Employers' Accounting for Postemployment Benefits". 
This statement requires that entities providing postemployment
benefits to their employees accrue the cost of benefits, if
attributable to employees' service already rendered. The Company
provides severance benefits for involuntarily terminated employees.

The cumulative effect of adopting SFAS 112 reduced income by
$3,896, net of zero tax benefit, in the first quarter of 1994.

In the fourth quarter of 1994 the Company initiated a plan to cut
costs and strengthen its competitive position by reducing its
workforce by 87 people.  These employees were primarily product
development, marketing and administrative personnel.  As a result,
the Company recognized a charge of $1,247 for severance costs and
outplacement assistance for employees.   In 1994, the Company paid
$303 to these employees.  At December 31, 1994, the Company had
accrued severance benefits of $944 related to this matter.  In
February, 1995, the Company further reduced its workforce and will
record a related charge to income of approximately $1,000. 


(6)    Joint Venture Investments

In 1992 the Company and Control Data Systems, Inc. established a
joint venture company, Metaphase Technology, Inc. (Metaphase), to
develop and market product data management software worldwide.  The
Company initially owned a 30% interest in Metaphase and increased
such interest to 50% during 1993. In March 1994 the Company and
Siemens Nixdorf Informationssysteme AG (SNI) formed a joint
venture, SDRC Software and Services GmbH (SDRC GmbH), to market
mechanical CAE/CAD/CAM software and services in Central Europe. 
The Company has a 50% interest in the joint venture.  Previously,
revenue from the Company's activities in this region was reported
on a consolidated basis.  The SDRC GmbH joint venture agreement
requires each venture partner to make additional equity
contributions in the event of venture losses.  SDRC's future
commitment is limited to $2,000 through 1996.  The Company's
investments in the joint ventures are accounted for on the equity
basis.  

Financial data for the year ended December 31, 1994 for Metaphase
and SDRC GmbH is presented below; data for 1993 and 1992 represents
only Metaphase:

(7)    Shareholders' Rights Plan

In 1988 the Board of Directors adopted a Shareholders' Rights Plan
to protect shareholders' interests in the event of an unsolicited
attempt to gain control of the Company. The Rights become
exercisable if a person acquires 20% or more of the Company's
outstanding common stock (Common Stock) or announces a tender offer
which would result in a person or group acquiring 20% or more of
the Common Stock (Distribution Date). If, at any time following the
Distribution Date, and the Company has not redeemed the Rights, the
Company becomes the surviving corporation in a merger or a person
becomes the beneficial owner of 20% or more of the Common Stock
(Triggering Date), each holder of a Right will have the right to
purchase shares of Common Stock having a value equal to two times
the Right's exercise price of $110.  If, at any time following the
Triggering Date, the Company is acquired in a merger or other
business combination transaction in which the Company is not the
surviving corporation, each holder of a Right shall have the right
to purchase shares of Common Stock of the acquiring company having
a value equal to two times the exercise price of the Right.  The
Rights expire on August 10, 1998, and may be redeemed by the
Company for $.0025 per Right.  

(8)     Common Stock and Employee Benefit Plans

In 1991 the shareholders adopted the 1991 Employee Stock Option
Plan.  Under the 1991 plan, the Company has reserved 5,300 shares
of previously unissued common stock.  Options to purchase such
shares may be granted to key employees and executive officers at
the fair market value at the date of grant.

In 1991 the shareholders also adopted the Director's
Non-Discretionary Stock Option Plan which converted the Amended and
Restated 1986 Stock Option Plan into a non-discretionary plan
allowing future grants to outside directors at the fair market
value at the date of grant.  Under the original 1986 plan, the
Company had reserved 7,000 shares of previously unissued common
stock. The status of all outstanding options previously granted to
employees remained unchanged.

In 1994 the shareholders adopted the 1994 Long-Term Stock Incentive
Plan, allowing stock incentives including stock options, stock
appreciation rights, stock awards, and combinations thereof, to be
granted to employees.  The number of shares with respect to which
stock incentives may be granted in one calendar year shall not
exceed 4% of the Company's issued and outstanding common stock.  
No stock incentives other than non-qualified stock options have
been granted under the 1994 plan.

Under the plans, employee options expire ten years from the date of
grant and are exercisable as follows: 33% on the first anniversary
of the grant date; 67% on the second anniversary; and all or any
remaining options on the third anniversary until expiration. 
Director options expire five years from the date of grant and are
exercisable 50% upon expiration of six months from the grant date
and all or any remaining options on the first anniversary of the
grant date until expiration.  As of December 31, 1994 there were
approximately 5,318 shares on which options were exercisable.

In 1990 the Company's Board of Directors established a Stock
Purchase Plan.  Under the plan all domestic full-time employees who
are non-executive officers are entitled to purchase the Company's
common stock at 90% of fair market value. Employees electing to
participate must contribute at least one percent with a maximum of
ten percent of the participants' base salary and commissions each
month.  All incidental expenses related to the issuance of these
shares including the 10% discount have been charged to income.  The
plan has no fixed expiration date, may be terminated by the Company
at any time and has no limitation on the number of shares that may
be issued.

The Company provides retirement benefits to employees principally
through contributory defined contribution retirement plans. 
Expenses related to these plans totaled $2,091, $943 and $1,686 in
1994, 1993 and 1992, respectively.



(9)     Commitments and Contingencies

In September 1994 the Company announced that in the course of an
internal examination, it had discovered that a number of purported
sales to or through third-party distribution channels apparently
did not reflect actual sales and that, as a result, it would be
necessary to restate the Company's financial results.  The Company
issued its restated financial statements for the years ended
December 31, 1993, 1992 and 1991 on January 16, 1995.  The Company
also announced that it had terminated its Vice President and
General Manager of Far East Operations.

On September 15, 1994 the first of a total of 12 class action
lawsuits and two derivative lawsuits was filed.  All of these suits
were filed in the United States District Court, Southern District
of Ohio and alleged a variety of causes of action under the federal
securities laws and Ohio corporate law.  Two of the class action
lawsuits were later voluntarily dismissed.  The remaining cases
were then consolidated into one proceeding.  The complaint demands
money damages in an unspecified amount.

The plaintiffs in this case presently consist of 22 individuals who
allegedly purchased shares of the Company's Common Stock between
February 3, 1992 and September 14, 1994.  The consolidated
complaint contains allegations intended to support the
certification of a class of plaintiffs.   The defendants include
the Company, certain directors and former officers. 

The Securities and Exchange Commission has commenced a formal,
private investigation of the Company arising out of the same facts
which gave rise to the above-described litigation.

The Company intends to defend itself vigorously in this litigation
but is unable, at this time, to determine the amount of loss, if
any, that may result from these matters.  Management does not
believe the ultimate outcome of these matters will have a material
adverse impact on the Company's financial position.

Pursuant to certain contractual obligations, the Company has agreed
to indemnify its directors and officers under certain circumstances
against claims arising from lawsuits. The Company may be obligated
to indemnify certain of its directors and officers for the costs
they may incur as a result of the lawsuits.

The Company is involved in other legal proceedings arising from the
normal course of business, none of which, in management's opinion,
is expected to have a material adverse impact on the Company's
financial position.
