                   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 June 27, 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, no par value ("SDRC Common Stock") to be issued in connection
with the proposed Merger (as defined herein).

The SDRC Common Stock offered hereby involves a certain degree of
risk.  See "Risk Factors" beginning on Page 21.

   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."), as amended (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, 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 second
trading day prior to the mailing date set forth in this Proxy
Statement/Prospectus to the CAMAX shareholders (the "Mailing Date"). 
The Applicable Market Value Per Share of SDRC Common Stock is
$29.75 per share.  The CAMAX shareholders will receive an aggregate
of 1,008,403 shares of SDRC Common Stock, or .0551 shares of SDRC
Common Stock for each share of CAMAX Common Stock owned, of which
10% will be held in escrow pursuant to the Merger Agreement and
Escrow Agreement.  Accordingly, at the Effective Date, the CAMAX
shareholders will receive an aggregate of 907,563 shares of SDRC
Common Stock; and, individually, the CAMAX shareholders will receive
 .0496 shares of SDRC Common Stock for each share of CAMAX Common
Stock owned, assuming the aggregate number of outstanding shares of
CAMAX Common Stock remains unchanged between the Record Date and the
Effective Date.  In addition, in accordance with the Merger
Agreement, SDRC will assume all of CAMAX's outstanding stock options
valued by Wessels, Arnold & Henderson, L.L.C. at $2.6 million as of
the date hereof.  (See "TERMS AND CONDITIONS OF THE PROPOSED MERGER
- - Opinion of Wessels, Arnold & Henderson; - Comparable Company
Analysis; - Comparable Transactions; and - Discounted Cash Flow
Analysis.")     

   Ten percent of the total shares to be issued to the CAMAX
shareholders in the Merger, 100,840 shares, 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.  However, because such retained shares are subject to
redemption for claims for indemnification by SDRC, there can be no
assurance that at the expiration of the Retention Period (as defined
below) there will be any retained shares remaining for distribution
to CAMAX shareholders.    

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 May ___, 1996.

                  SUMMARY OF THE PROXY STATEMENT/PROSPECTUS

The following is a summary of certain information contained
elsewhere in this Proxy Statement/Prospectus and the documents
incorporated herein by reference.  This is not intended to be a
summary of all information relating to the Merger and is qualified
in its entirety by reference to the more detailed information
contained elsewhere in this Proxy Statement/Prospectus, including
the Annexes hereto, and the documents incorporated by reference in
this Proxy Statement/Prospectus.

Introduction:

The Boards of Directors of CAMAX and SDRC have each unanimously
approved the Agreement of Merger and Plan of Reorganization dated as
of January 16, 1996, as amended on May 6, 1996 (the "Merger
Agreement") pursuant to which CAMAX will be merged with and into
Acquisition Corp., a wholly-owned subsidiary of SDRC, if the
shareholders of CAMAX approve the Merger by the requisite
shareholder vote and certain other conditions are satisfied.  The
CAMAX Board of Directors, at meetings held on January 13, and
January 16, 1996, at which all directors were present, determined
that the Merger is fair to and in the best interests of CAMAX and
its shareholders and unanimously approved the Merger Agreement and
unanimously resolved to recommend that the shareholders of CAMAX
vote for the adoption of the Merger and Merger Agreement.  In
connection with this decision, the CAMAX Board of Directors received
advice from CAMAX management, Deloitte & Touche LLP, its accounting
advisor, Wessels, Arnold & Henderson, LLC ("WA&H"), its financial
advisor, and Dorsey & Whitney, LLP, its legal advisor.  On May 6,
1996, the Board of Directors of CAMAX held a special meeting to
consider certain amendments to the Merger Agreement.  First, the
Board of Directors of CAMAX considered and unanimously approved an
amendment to Section 2.1 of the Merger Agreement which modified the
calculation of the Applicable Value Per Share of SDRC Common Stock
by changing the Valuation Period from the 20-trading day period
ending on the fifth trading day prior to the Effective Date to the
20-trading day period ending on the second trading day prior to the
date of the Proxy Statement/Prospectus.  Second, the Board of
Directors of CAMAX considered and unanimously granted direction to
management of CAMAX to make any further changes to the Merger
Agreement it deems necessary in order to carry out and effectuate
the Merger as previously approved, including, but not limited to,
amending Section 8.1(iv) of the Merger Agreement to extend the
termination date of the Merger Agreement to July 31, 1996.  At its
May 6, 1996 special meeting, the Board of Directors of CAMAX once
again determined that the Merger is fair to and in the best
interests of CAMAX and its shareholders and resolved to recommend
that the shareholders of CAMAX vote for adoption of the Merger and
the Merger Agreement.

At the January 13, 1996 meeting, WA&H rendered to the CAMAX Board of
Directors its oral opinion (subsequently confirmed in writing at the
January 16, 1996 meeting) that as of January 16, 1996 and based on
the procedures followed, factors considered and assumptions made by
WA&H, 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.  See
"TERMS AND CONDITIONS OF THE PROPOSED MERGER - Background and
Reasons for the Merger."

On January 16, 1996 the SDRC Board of Directors met and unanimously
approved the Merger and Merger Agreement.  The SDRC Board of
Directors relied upon the advice of its management, Price Waterhouse
LLP, its accounting advisor, and Dinsmore & Shohl, its legal
advisor, to make the determination to approve the Merger and Merger
Agreement.  SDRC did not retain an outside financial advisor for
this transaction.

   Beneficial Ownership by Officers and Directors:  As of the close
of business on May 22, 1996, the executive officers and directors
of CAMAX and their affiliates beneficially owned 7,750,541 shares,
or approximately 39.9%, of the outstanding shares of CAMAX Common
Stock. This figure includes options for the purchase of shares of
CAMAX Common Stock which were exercisable on that date.  See "CAMAX
MANUFACTURING TECHNOLOGIES, INC. - Principal Shareholders of 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 computer-aided manufacturing ("CAM")
leadership in the computer-aided design/computer-aided manufacturing
industry and bring change and improvement to such industry. 
Management of CAMAX determined that it needed a partner to reach its
goal of being the CAM leader in the industry and believed that the
solutions for success in the mechanical engineering marketplace
would be to possess technical expertise in certain key areas: 
computer-aided design ("CAD"), CAM, computer-aided engineering
("CAE") and product data management ("PDM").

SDRC, consistent with its strategic objective of becoming the
leading world-wide supplier of team engineering solutions that
encompass CAD, CAM, CAE and PDM, early in 1995 initiated an in-depth
evaluation of the CAM segment of the mechanical design automation
industry for the purpose of assessing the CAM industry.  From this
in-depth strategic analysis, SDRC determined that a cornerstone of
its long-term strategy would be to offer concurrent engineering
solutions with balanced strength in CAD, CAM, CAE and PDM. 
Recognizing the opportunities to further strengthen and expand its
CAM offering, SDRC began to look at ways to improve its position in
the CAM industry.  SDRC evaluated the various competitors in the CAM
market and found that CAMAX was the company that most closely met
its ideal profile.

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 Thomas A. 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 another 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.  CAMAX retained WA&H
pursuant to an engagement letter dated November 10, 1995.  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 other 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 legal 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. 

During the first week of 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 SDRC's Vice
President and General Counsel and SDRC's outside legal counsel to
complete negotiation of the Merger Agreement. 

The terms of the Merger Agreement were negotiated with the objective
of structuring the transaction in a manner that would be
advantageous from a tax, financial and accounting standpoint to each
of SDRC, CAMAX and CAMAX's shareholders.  See "TERMS AND CONDITIONS
OF THE MERGER -- Federal Income Tax Consequence."  SDRC and CAMAX
determined, upon the advice of their financial, legal and accounting
advisors, that a merger transaction accounted for as a pooling of
interests would allow the companies to achieve their objectives. 
Following the approval by the respective boards of directors of SDRC
and CAMAX, the parties signed the Merger Agreement on January 16,
1996.  


    
   Terms of 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 second trading day prior to the Mailing
Date.  The Applicable Market Value Per Share of SDRC Common Stock is
$29.75 per share.  The CAMAX shareholders will receive an aggregate
of 1,008,403 shares of SDRC Common Stock, or .0551 shares of SDRC
Common Stock for each share of CAMAX Common Stock owned, of which
10% will be held in escrow pursuant to the Merger Agreement and
Escrow Agreement.  Accordingly, at the Effective Date, the CAMAX
shareholders will receive an aggregate of 907,563 shares of SDRC
Common Stock; and individually, CAMAX shareholders will receive
 .0496 shares of SDRC Common Stock for each share of CAMAX Common
Stock owned assuming the aggregate number of outstanding shares of
CAMAX Common Stock remains unchanged between the Record Date and the
Effective Date.  In addition, in accordance with the Merger
Agreement, SDRC will assume all of CAMAX's outstanding stock options
valued by WA&H at $2.6 million as of the date hereof.  (See "TERMS
AND CONDITIONS OF THE PROPOSED MERGER - Opinion of Wessels, Arnold 
& Henderson; - Comparable Company Analysis; - Comparable
Transactions; and - Discounted Cash Flow Analysis").  Ten percent of
the total 1,008,403 shares or 100,840 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
fair 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 notification under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 ("HSR Act"), SDRC's registration under the
Securities Act of the SDRC Common 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 February 28, 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 an opinion from CAMAX's intellectual property counsel; receipt of
consents necessary to permit SDRC to continue CAMAX's business after

documents.  SDRC has no present intention to waive or modify any of
the conditions to Closing.

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 July 31, 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."

Effect of the Merger on CAMAX Stock Options:  At the Effective
Date, SDRC 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 two 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
71,000 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&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 entirety.  See "TERMS AND CONDITIONS OF
THE PROPOSED MERGER - CAMAX's Financial Advisors", " - Opinion of
Wessels, Arnold and Henderson"; and Annex B.


[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." 

Comparison of Holders of SDRC Common Stock and CAMAX Common Stock: 
The rights of holders of CAMAX Common Stock are currently governed
by Minnesota law, CAMAX's Articles of Incorporation, and its Bylaws. 
At the Effective time, CAMAX shareholders (except holders who
perfect their dissenters rights) will become shareholders of SDRC,
and their rights will be governed by Ohio law and by SDRC's Amended
Articles  of Incorporation and Amended Code of Regulations.  The
rights of a holder of SDRC Common Stock are similar in some respects
and different in other respects from the rights of a holder of CAMAX
Common Stock. For a detailed explanation of these rights, see
"COMPARISON OF RIGHTS OF SHAREHOLDERS."

    Except for the historical information contained herein, the
discussion in this Proxy Statement/Prospectus contains forward-looking 
statements that involve risks and uncertainties.  SDRC's and
CAMAX's actual results could differ materially from those discussed
in the forward-looking statements.  Factors which could cause or
contribute such differences include, but are not limited to, those
discussed in the sections entitled "Risk Factors," and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations", as well as those discussed elsewhere in this Proxy
Statement/Prospectus and any documents incorporated herein by
reference.    

RISK FACTORS

The following factors regarding the Merger and SDRC should be
carefully considered:

   Shares Held in Escrow.  Of the total number of 1,008,403 shares
of SDRC Common Stock to the issued in the Merger, 10% or 100,840
shares will be held in escrow as the sole source from which any
claims by SDRC for indemnification under the Merger Agreement may be
satisfied.  Accordingly, up to 10% of the total consideration to be
received by CAMAX shareholders is subject to the risk of forfeiture
in the event SDRC becomes entitled to indemnification, for example
as the result of CAMAX's breach of representations and warranties
contained in the Merger Agreement.  Further, during the term of the
escrow, which runs until the earlier of the first anniversary of the
Effective Date or the date SDRC files its Report on Form 10-K for
the year ending December 31, 1996, the shares held in escrow are
non-transferable and cannot be pledged as security for loans.  See
"TERMS AND CONDITIONS OF THE PROPOSED MERGER -- Escrow
Agreement."    

Highly Competitive Industry.  SDRC is engaged in the development and
marketing of software products that include CAE, CAD, CAM and PDM. 
The market for CAE, CAD, CAM and PDM software is intensely
competitive.  Certain of SDRC's existing and potential competitors
may have more extensive technical, marketing and financial resources
than SDRC.  There can be no assurance that competitive pressures
will not adversely affect SDRC's business in the future.

Rapid Technological Change.  The CAE, CAD, CAM and PDM industries
are characterized by rapid technological advances in both software
and hardware.  Consequently, to maintain its competitive position,
SDRC must continually enhance its existing products, pursue the
development and introduction of new products and remain on the
forefront of a number of advanced technologies.  To respond to
rapidly changing technology, SDRC will be required to continue to
make substantial investments in research and development, and there
can be no assurance that its efforts will continue to be successful.

Recent Management Changes; Dependence on Key Personnel.  In late
1994 and early 1995, SDRC effected a number of changes in its
management team which is now almost entirely new.  Although the
Company's first fiscal year under the direction of the new
management was very successful operationally from a financial
performance standpoint, there can be no assurance that such success
will continue.  SDRC's continued success is dependent upon its
continued ability to attract and retain qualified management and
other employees.  Competition for such employees is intense, and the
loss of certain employees or SDRC's inability to attract, retain and
motivate highly skilled employees in the future could adversely
affect its business.

International Business.  A substantial portion of SDRC's revenues
are derived from its business conducted in Europe and the Asia
Pacific region.  There are risks in the operation of business
outside the United States, including among others, the difficulty of
administering businesses abroad, exposure to foreign currency
fluctuations and devaluations or restrictions on money supplies,
foreign and domestic export laws and regulations, taxation tariffs,
import quotas and restrictions and other political and economic
events beyond SDRC's control.  SDRC has not experienced any material
effects of these risks as of yet, however, there can be no assurance
that some or all of these effects will not affect SDRC in the
future.

Lack of Dividends.  SDRC has not paid cash dividends on its
common stock in the last five years and cash dividends are not
presently contemplated at any time in the foreseeable future.

Attraction and Retention of Key Personnel.  SDRC's ability to
develop commercially viable products and to maintain a competitive
position in a business environment characterized by intense
competition and technological change depends upon, among other
factors, its ability to attract and retain skilled programming,
engineering, management, sales and marketing personnel. Competition
for the services of such personnel is intense, and there can be no
assurance that SDRC will be able to attract or retain the personnel
necessary for SDRC's success.  The loss by SDRC of the services of
any of its key personnel could have a material adverse impact on the
business and prospects of SDRC.

Domestic and International Economic Conditions.  SDRC's business
is subject to general economic conditions, both in the United States
and abroad.  A substantial decline in economic conditions in any
significant geographic area could have a material adverse effect
upon the results of SDRC's operations and financial condition.

Integration of Operations.  SDRC entered into the Merger
Agreement with the expectation that the Merger will result in
beneficial synergies.  See "TERMS AND CONDITIONS OF THE PROPOSED
MERGER - Background and Reasons for the Merger."  Achieving the
anticipated benefits of the Merger will depend in part upon whether
the integration of the two companies' businesses is accomplished in
an efficient and effective manner, and there can be no assurance
that this will occur.  The successful combination of companies in a
high technology industry may be more difficult to accomplish than in
other industries.  The combination of the two companies will
require, among other matters, integration of SDRC's and CAMAX's
respective engineering and programming personnel and product
offerings and coordination of their sales, marketing and research
and development efforts.  There can be no assurance that such
integration will be accomplished smoothly or successfully.  The
difficulties of such integration may be increased by the necessity
of coordinating geographically separated organizations.  The
integration of certain operations following the Merger will require
the dedication of management resources which may temporarily
distract attention from the day-to-day business of the combined
company.  The inability of management to integrate the operations of
the two companies successfully could have a material adverse effect
on the business and the results of operations of SDRC.

Distributors and Customers.  There can be no assurance that
distributors and present and potential customers of SDRC and CAMAX
will continue their current buying patterns without regard to the
announced Merger.  Certain customers of the two companies may defer
purchasing decisions as they evaluate SDRC's future product strategy
and consider aggressive pricing programs of certain competitors of
the companies.  Any such deferrals could have a material adverse
effect upon the results of operations of SDRC subsequent to the
Merger.

Intellectual Property Protection.  Each of SDRC and CAMAX
considers its respective intellectual property, including
trademarks, patents and copyrights, to be significant to its
business.  There can be no assurance, however, that any of the
intellectual property rights currently in place will provide
adequate protection for the technologies or products they cover.  In
addition, the process of obtaining and protecting intellectual
property rights can be long and expensive.




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) May 23, 1996, the last day of the 20-day
trading period ending two days prior to the Mailing Date.  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 .0551, which is the actual number
of shares of SDRC Common Stock into which each share of CAMAX Common
Stock is to  be converted based upon May 23, 1996 being the end date
of the 20 trading day period and the price 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
January 16, 1996        $23.75              $1.3086

[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, 1991, 1992 and 1993 and for each of the two years in the period
ended December 31, 1992 for SDRC and CAMAX has been derived from the
consolidated financial statements of SDRC and CAMAX as of and for
those periods.  The selected consolidated financial information as
of December 31, 1994 and 1995 and for each of the three years in the
period ended December 31, 1995 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
historical consolidated financial information for SDRC and CAMAX for
the three-month periods ended March 31, 1995 and 1996 has been
derived from the consolidated unaudited financial statements of SDRC
and CAMAX and include, in the opinion of SDRC's and CAMAX's
management, respectively, 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 $1,882,000.  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 represent the
actual Exchange Ratio which converts each share of
CAMAX Common Stock into .0551 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 two days prior to the Mailing Date.

During 1993-1994, the Company's level of expenses increased to support 
technological development and revenue growth. As anticipated revenue
growth did not materialize, the Company's expenses exceeded revenue
resulting in operating and net losses.  In 1995, the anticipated
cost of the class action lawsuit settlement, net of estimated insurance
proceeds, was included in the results of the operations.

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, 1993 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
 .0551 for CAMAX Common Stock which is based on the assumption of
18,293,321 shares of CAMAX Common Stock issued and outstanding as of
May 23, 1996.  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

                             VOTING AND PROXIES

Date, Time and Place of Special Meeting of Shareholders


    
   This Proxy Statement/Prospectus is being furnished to the
shareholders of CAMAX Manufacturing Technologies, Inc., a Minnesota
corporation ("CAMAX"), in connection with the solicitation by the
Board of Directors of CAMAX of proxies to be used at a special
meeting of shareholders (the "Special Meeting") to be held on
June 27, 1996, at 10:00 a.m., Central Daylight Savings
Time, at CAMAX's headquarters at 7851 Metro Parkway, Minneapolis,
Minnesota 55425, and at any adjournments thereof.  This Proxy
Statement/Prospectus and the enclosed form of proxy are first being
sent to shareholders of CAMAX on or about May 28, 1996.    

Proposal to Merge CAMAX into Acquisition Corp.

At the Special Meeting, shareholders of CAMAX will be asked to
adopt a Merger and an Agreement of Merger and Plan of Reorganization
dated as of January 16, 1996, by and among CAMAX, Structural
Dynamics Research Corporation ("SDRC") and SDRC Systems, Inc.
("Acquisition Corp."), as amended on May 6, 1996 (the "Merger
Agreement").  Pursuant to the Merger Agreement, CAMAX will merge
with and into Acquisition Corp. (the "Merger").  See "TERMS AND
CONDITIONS OF THE PROPOSED MERGER" below.

Record Date and Outstanding Shares

   Shareholders of record of CAMAX Common Stock at the close of
business on May 22, 1996 (the "Record Date") are entitled to notice
of and to vote at the Special Meeting.  As of the Record Date, there
were approximately 233 shareholders of record of CAMAX Common
Stock.  As of the Record Date there were 18,293,321 shares of
CAMAX Common Stock outstanding.  However, due to the potential
exercise of options to purchase CAMAX Common Stock, it is possible
that there may be additional  shares of CAMAX Common Stock
outstanding as of the Effective Date.  Except for the shareholders
identified below under "CAMAX MANUFACTURING TECHNOLOGIES, INC. -
Principal Shareholders of CAMAX," there were no persons known to the
management of CAMAX to be the beneficial owners of more than 5% of
the outstanding shares of CAMAX Common Stock.    

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.

It is not expected that any matter not referred to herein will be
presented for action at the Special Meeting.  If any other matters
are properly brought before the Special Meeting, the persons named
in the proxies will have discretion to vote on such matters in
accordance with their best judgment.  However, shares represented by
proxies will not be used to vote "FOR" postponement or adjournment
of the Special Meeting for the purpose of allowing additional time
for soliciting additional votes "FOR" the approval of the Merger and
the Merger Agreement.  Only those shares represented in person at
the Special Meeting will be entitled to vote "FOR" postponement or
adjournment of the Special Meeting for the purpose of allowing
additional time for soliciting additional votes "FOR" the approval
of the Merger and the Merger Agreement.  The grant of a proxy will
also confer discretionary authority on the persons named in the
proxy as proxy appointees to vote in accordance with their best
judgment on matters incident to the conduct of the Special Meeting,
except as stated in the preceding sentence.

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.

   6,615,290 shares of CAMAX Common Stock (excluding shares subject
to stock options) are beneficially owned by directors and executive
officers of CAMAX and their affiliates at the Record Date (36.2% of
the total number of outstanding shares of CAMAX Common Stock at such
date).  Approval of the Merger and the Merger Agreement requires the
affirmative vote of holders of a majority of the shares of CAMAX
Common Stock on the Record Date.  It is expected that the entire
36.2% of the total number outstanding shares of CAMAX Common Stock
on the Record Date owned by the directors, executive officers and
their affiliates will be voted in favor 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
Data Management ("PDM") 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 Thomas A. 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 CAM 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 another 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 other 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 & Whitney LLP and Deloitte & 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 & Whitney LLP's legal due
diligence, and (iv) the results of Deloitte & Touche LLP's
accounting due diligence.  On May 6, 1996, the Board of Directors of
CAMAX held a special meeting to consider certain amendments to the
Merger Agreement.  First, the Board of Directors of CAMAX considered
and unanimously approved an amendment to Section 2.1 of the Merger
Agreement which modified the calculation of the Applicable Value Per
Share of SDRC Common Stock by changing the Valuation Period from the
20-trading day period ending on the fifth trading day prior to the
Effective Date to the 20-trading day period ending on the second
trading day prior to the date of the Proxy Statement/Prospectus. 
Second, the Board of Directors of CAMAX considered and unanimously
granted direction to management of CAMAX to make any further changes
to the Merger Agreement it deems necessary in order to carry out and
effectuate the Merger as previously approved, including, but not
limited to, amending Section 8.1(iv) of the Merger Agreement to
extend the termination date of the Merger Agreement to July 31,
1996.  At its May 6, 1996 special meeting, the Board of Directors of
CAMAX once again determined that the Merger is fair to and in the
best interests of CAMAX and its shareholders and resolved to
recommend that the shareholders of CAMAX vote for adoption of the
Merger and the Merger Agreement.

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

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.  6,615,290 shares
of CAMAX Common Stock (excluding shares subject to stock options)
are beneficially owned by directors and executive officers of CAMAX
and their affiliates at the Record Date (36.2% of the total number
of outstanding shares of CAMAX Common Stock at such date).  Approval
of the Merger and the Merger Agreement requires the affirmative vote
of holders of a majority of the shares of CAMAX Common Stock on the
Record Date.  It is expected that the entire 36.2% of the total
number of outstanding shares of CAMAX Common Stock on the Record
Date owned by the directors, executive officers and their affiliates
will be voted in favor 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 PDM,
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 PDM  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 PDM segments of SDRC's business. Since many companies
want an integrated solution, there would be an opportunity to gain
CAD and PDM 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 25,000
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 product 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.  In connection with its evaluation
of CAMAX, SDRC'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.

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.  An amendment to the Merger Agreement
to change the date on which the companies would value the SDRC stock
to determine the exchange ratio and to extend the termination date
to July 31, 1996 was adopted by the parties on May 6,
1996.  A copy of the Amendment to the Agreement of Merger and Plan
of Reorganization is included herein in Annex A.    

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 July 31, 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" is 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 second trading day prior to the
Mailing Date which is $29.75 per share.  On the Effective Date, each
CAMAX shareholder will receive .0551 shares of SDRC Common
Stock (which does not include that number of shares to be retained
by SDRC under the Merger Agreement and Escrow Agreement) for each
share of CAMAX Common Stock owned immediately prior to the
Merger.  In addition, in accordance with the Merger Agreement, SDRC
will assume all of CAMAX's outstanding stock options valued by
Wessels, Arnold & Henderson, L.L.C. at $2.6 million as of the date
hereof.    

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"), 100,840 shares of SDRC Common Stock
which represent 10% of the total 1,008,403 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 of
$29.75 which is equal to the Applicable Market Value Per Share of
SDRC Common Stock as of the Mailing Date.    

The procedures for redemption by SDRC of all or part of the
Retention Shares from escrow is set forth in the Escrow Agreement,
a copy of which is appended hereto as Annex D (the "Escrow
Agreement").  The Escrow Agreement provides that whenever either (a)
a certificate signed by SDRC and the representatives named in the
Escrow Agreement or (b) a certified copy of a final non-appealable
judgment of a court of competent jurisdiction is delivered to the
Escrow Agent determining that an amount is due to SDRC pursuant to
the indemnification provisions of the Merger Agreement and further
specifying the number of shares of SDRC Common Stock, valued as
described in the preceding paragraph, to be transferred, the Escrow
Agent shall promptly cause certificates representing the appropriate
number of retained shares to be delivered to SDRC.  The items in the
Merger Agreement which would cause SDRC to seek redemption of the
Retention Shares are losses, damages, expenses, deficiencies or
costs resulting from any breach or misrepresentation by CAMAX of any
representation, warranty or covenant made by CAMAX in the Merger
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.  Because the
Retention Shares are subject to redemption for claims for
indemnification by SDRC, there can be no assurance that at the
expiration of the Retention Period, there will be any Retention
Shares remaining for distribution to the CAMAX shareholders.

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 100,840 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.  Neither the
Retention Shares nor each CAMAX shareholder's respective interest in
the Retention Shares is transferable until the expiration of the
Retention Period.  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.  The
right of a CAMAX shareholder to receive and transfer the Retention
Shares, if any, at the termination of the Retention Period will not
be affected by such shareholder's disposition, prior to the
termination of the Retention Period, of any or all of the shares of
SDRC Common Stock issued to such shareholder upon consummation of
the Merger.  Pursuant to the terms of the Merger Agreement, each
CAMAX shareholder, upon consummation of the Merger, will become the
beneficial owner of that aggregate number of shares of SDRC Common
Stock which includes that proportion of the Retention Shares
attributable to such shareholder.

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 May 22, 1996, there were outstanding options to purchase
3,179,109 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, 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 will qualify as a "party to a reorganization" within
the meaning of Section 368(b) of the Code;

(b) no gain or loss will be recognized by SDRC, Acquisition Corp.
or CAMAX as a consequence 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 federal income tax basis of the SDRC Common Stock to be
received by the 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 interest 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;

(e) the holding period of 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 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; 

(f) 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; and

(g) 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, subject
to the provisions of Section 302 of the Code.

The above tax opinion will be based upon certain customary
representations and assumptions referred to in the opinion letter to
be provided at the Closing.  The Closing of the Merger 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.  The mechanism in place to ensure
that the CAMAX shareholders meet the continuity of interest
requirements of the Treasury Regulations, CAMAX will solicit from
its management and shareholders holding 1% or more of the CAMAX
Common Stock representation letters to the effect that such
shareholders will retain their shares for the requisite period of
time.  The representation letters will evidence these shareholders'
intent to retain their shares.  If members of management or 1%
shareholders should sell 50% of their shares before the required
holding period has expired, a lack of such intent may be evident. 
If management and the 1% shareholders do not have the requisite
intent to hold the shares, then there is no continuity of interest,
and the consequence will be that the Merger will not be treated as
a tax-free reorganization.  Although CAMAX will use its best
efforts, there can be no assurance that CAMAX will be able to obtain
such letters from its management or 1% or greater shareholders.

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 February 28,
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.

Conditions to Closing

The Merger Agreement must be approved by the affirmative vote of a
majority 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 also subject to receipt of an opinion of SDRC's counsel
with respect to certain tax matters.  See "Federal Income Tax

The obligations of SDRC and CAMAX to consummate the Merger are
further subject to various other conditions set forth in the Merger

actions, proceedings or investigations of any kind pending or
threatened with respect to the transactions contemplated by the
Merger Agreement and the filing of a pre-merger notification with
the Department of Justice and the Federal Trade Commission under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the
expiration of all applicable waiting periods.   

SDRC's obligation to consummate the Merger is further conditioned,
without limitation, upon the following:  CAMAX's representations and

receipt of material consents necessary to permit SDRC to continue
CAMAX's business after the Effective Date; severance arrangements

CAMAX of certain closing documents.

CAMAX's obligation to consummate the Merger is further conditioned,
without limitation, upon the following:  SDRC's representations and
warranties being 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. 

In the event certain material conditions to the parties' obligations
to close, including, but not limited to, receipt of certain legal
opinions, tax opinions or accountants' letters with respect to the
treatment of the Merger as a pooling of interests, are waived by the
parties, SDRC and CAMAX undertake to file a post-effective amendment
to its Registration Statement and will re-solicit the approval of
the Merger by the CAMAX shareholders pursuant to an amended Proxy
Statement/Prospectus contained in the amended Registration
Statement.

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 prior to the Effective Date by written notice delivered
by SDRC to CAMAX or by CAMAX to SDRC in the following instances: (a)
by SDRC and Acquisition Corp. if any conditions precedent to closing
the transaction to be satisfied or performed by CAMAX have not been

automatically if the CAMAX shareholders fail to approve the Merger
Agreement.

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
3,179,109 options outstanding on the Record Date, 1,105,000 were
held by Mr. Majteles, 493,000 were held by Mr. Furness and
997,250 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, of which
$10,675 remains to be paid; (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.  CAMAX
selected WA&H as its financial advisor because of WA&H's reputation
and experience in the technical software industry.  In connection
with its engagement of a financial advisor, CAMAX did  not interview
any other financial advisors.  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.  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 financial statements of SDRC
provided by SDRC's management and those publicly available from
financial analysts, (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.  With respect to the financial projections for SDRC,
WA&H relied upon the publicly available financial analysts'
projections.  SDRC verbally confirmed to WA&H that it did not
disagree with such investment analysts' projections at that time. 
SDRC's internal forecasts at that time contained no variations from
the investment analyst's projections. CAMAX provided WA&H with
projections of the following income statement items for the years
1996, 1997 and 1998:  net sales, cost of sales, gross margin,
operating expenses, operating income, interest expense, net income
before income taxes, income taxes and net income.  The projections
obtained by WA&H for SDRC were for similar income statement items. 
With respect to the
financial projections for CAMAX, WA&H compared CAMAX's historical
financial budgets to CAMAX's actual historical financial results. 
The CAMAX projections were prepared by CAMAX management to
facilitate ongoing valuation discussion with WA&H and solely for the
purpose of rendering WA&H's fairness opinion, particularly the
stand-alone discounted cash flow valuation analysis.  These
projections assumed that CAMAX would operate as a stand-alone entity
and that the merger was not consummated.  CAMAX projected that,
between 1996 and 1999, revenue would grow approximately 15% each
year, gross profit would grow approximately 90% each year, operating
expenses as a percentage of revenue would range from approximately
70% to 77% annually, operating income as a percentage would range
from approximately 3% to 20% annually, and net income as a
percentage of revenue would range from approximately 8% to 13%
annually; these projections, however, are subject to a number of
company and industry factors that involve risks and uncertainties
that could materially affect the financial results actually obtained
by CAMAX. WA&H found that CAMAX's budgeting process had been
reasonably accurate in predicting its forward-looking results.  WA&H
also believed that the projections for CAMAX and SDRC were generally
consistent with the projections for the CAD/CAM industry as a whole,
noting, however, that revenues for 1994 declined from 1993, although
CAMAX explained that such fluctuation was attributable to a decline
in software sales (primarily due to the decrease in sales of
SmartCAM) and a decline in other sales attributable to a de-emphasis
on the resale of hardware products.  Therefore, in its analysis,
WA&H made no adjustments to either CAMAX's or SDRC's projected
financial performance.  CAMAX's independent accountants have not
examined, reviewed or compiled any of CAMAX's projections nor have
they expressed any conclusion or provided any other form of
assurance with respect to such projections, and accordingly, they
assume no responsibility for them.     

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").  The Comparable Companies are all engaged
in the development, support and marketing of CAD software.  The
comparable companies generally sell their products and services to
designers and engineers.  The Comparable Companies used for this
analysis were the most comparable companies to CAMAX at the time of
the analysis.  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, $30,000,000 to be offered as consideration in the Merger,
plus $2,600,000 which is the value of the options issued under the
CAMAX Option Plans and the CAMAX Non-Qualified Options, except for
the unvested options held by Mr. Majteles, and, as to the Comparable
Companies, on market prices and other information available as of
the date of the Wessels Opinion.  It should be noted that because
all outstanding stock options will be assumed by SDRC pursuant to
the Merger Agreement and will remain exercisable for their original
terms, which in most cases extend beyond the Effective Date, the
value assigned to such options, solely for purposes of valuation
comparison, is not included in the total Merger consideration to be
received by CAMAX shareholders on the Effective Date. The total
Merger consideration will be $30,000,000.  Multiples of future
earnings were based on projected earnings as estimated publicly by
WA&H and First Call Consensus, a Thompson Financial Services
company.  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,
a median of 17.7x, a high of 50.5x and a low of 13.6x 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, a median
of 14.3x, a high of 26.4x and a low of 11.1x 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).  In such analysis, WA&H compared
multiples of selected financial data for the Merger with those of
the following transactions between the target and the acquiror,
respectively, in the technical software industry:  Valid Logic
Systems Inc. - Cadence Design Systems Inc., Vantage Analysis
Systems,Inc. - Viewlogic Systems, Inc., Eesof, Inc. - Hewlett
Packard Corporation, Logic Modeling Corporation - Synopsys Inc.,
Evans & Sutherland (CDRC) - Parametric Technology Corp., PDA
Engineering - MacNeal-Schwendler Corporation, GeoGraphix, Inc. -
Landmark Graphics Incorporation, Rasna Corporation - Parametric
Technology Corp., and Integrated Silicon Systems, Inc - ArcSys, Inc. 
The Comparable Transactions were selected based primarily on the
target company's involvement in the technical software industry.  
The Comparable Transactions used for this analysis were the most
comparable transactions to the Merger at the time of the analysis.
The Comparable Transactions all involve companies that develop,
support and market software products that are used by engineers and
designers for CAD, CAE or electronic design.  WA&H categorizes
software companies that develop, support and market software
products that are used by engineers and designers as "technical
software" companies.  In analyzing the Comparable Transactions, WA&H
examined the multiples of transaction values to the latest twelve
months' operating results in relation to the projected growth rate
of the target company at the time of the acquisition.  Although the 
multiples paid in the Comparable Transactions were, on average,
higher than the multiples proposed to be paid to CAMAX by SDRC, the
multiples paid in the Comparable Transactions were lower when
adjusted for the expected growth rate of the respective target
companies.  WA&H believes that there is a direct correlation between
the expected growth rate of the target company and the price that
the acquiring company is willing to pay.  In each of the Comparable
Transactions the target companies had different expected growth
rates.  Therefore, WA&H, in its fairness opinion analysis, believed
that it was not appropriate to examine the price paid in a 
Comparable Transaction without adjusting for differences in future
expected growth between CAMAX and the target companies used in the
Comparable Transaction analysis.  The expected growth rate of CAMAX
was less than the expected growth rates of companies in the
Comparable Transactions, and therefore, an acquiror of CAMAX cannot
be expected to pay as high of a multiple of trailing twelve months'
operating results as the acquirors in the Comparable Transactions. 
WA&H calculated the following valuation multiples based on
$30,000,000 to be offered as consideration in the Merger, plus
$2,600,000 which is the value of the options issued under the CAMAX
Option Plans and the CAMAX Non-Qualified Options, except for the
unvested options held by Mr. Majteles, and, as to the Comparable
Transactions, on the consideration paid to the target company.  It
should be noted that because all outstanding stock options will be
assumed by SDRC pursuant to the Merger Agreement and will remain
exercisable for their original terms, which in most cases extend
beyond the Effective Date, the value assigned to such options,
solely for purposes of valuation comparison, is not included in the
total Merger consideration to be received by CAMAX shareholders on
the Effective Date. The total Merger consideration will be
$30,000,000.  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 growth
rates used were based on information provided by WA&H.  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.  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 target companies in the Comparable Transactions, the multiples
of operation results achieved by the CAMAX shareholders was
approximately equal to that realized by the shareholders of the
target companies in 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 Beta used in WA&H's analysis to determine the
discount rate which was applied to CAMAX's projected cash flows
represents the Beta of the publicly-traded Comparable Companies,
according to First Call Consensus, a Thompson Financial Services 
company.  Because the net present value of the projected cash flows
was calculated using a "public company" discount rate, WA&H
subsequently applied a private company discount of 30% to the net
present cash flows.  Such additional discount represents the fact
that an investor would typically apply a discount to the value of a
private company's equity due to the relative lack of liquidity
versus the publicly-traded equity securities.  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 $30,000,000, plus $2,600,000 which is the value of the
options issued under the CAMAX Option Plans and the CAMAX
Non-Qualified Options,
 except for the unvested options held by Mr.
Majteles, was greater than the present value of CAMAX's cash flows
under the range of discounted cash flow valuations discussed
above.  It should be noted that because all outstanding stock
options will be assumed by SDRC pursuant to the Merger Agreement and
will remain exercisable for their original terms, which in most
cases extend beyond the Effective Date, the value assigned to such
options, solely for purposes of valuation comparison, is not
included in the total Merger consideration to be received by CAMAX
shareholders on the Effective Date. The total Merger consideration
will be $30,000,000.    

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. 

    Except for the historical information contained herein, the
discussion in this Proxy Statement/Prospectus contains forward-looking 
statements that involve risks and uncertainties.  SDRC's and
CAMAX's actual results could differ materially from those discussed
in the forward-looking statements.  Factors which could cause or
contribute such differences include, but are not limited to, those
discussed in the sections entitled "Risk Factors," and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations", as well as those discussed elsewhere in this Proxy
Statement/Prospectus and any documents incorporated herein by
reference.    

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 Merger will not result in any material adverse effect 
to the results of operation or financial condition of SDRC.

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.

Among the most important effects of the Merger, SDRC anticipates
that the growth in resources will provide for the swift and
effective augmentation of SDRC's CAM business.  The products
currently being developed and offered by CAMAX are complementary to
SDRC's and are expected to strengthen and enhance SDRC's position in
the CAM industry in the near future following the Merger.  Moreover,
because CAMAX products and personnel are expected to be easily
integrated into SDRC, SDRC anticipates being able to capitalize on
the integration of complementary companies.

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. 

On September 14, 1994, SDRC announced that in the course of an
internal review of the business practices of its Far East
Headquarters Operations, it had identified that certain shipments of
its products intended for sale to or through third party
distribution channels apparently did not represent valid sales and
that as a result it expected to restate its financial statements for
1992, 1993 and the first two quarters of 1994.  SDRC further
announced that it had dismissed its vice president and general
manager of its Far East Operations, Tony Tolani, and had engaged
outside legal counsel to further examine its internal controls and
business practices.  SDRC also stated that it expected to report a
net loss of $.15 to $.25 per share for the third quarter of 1994,
well below analysts' expectations of earnings of $.11 per share.

Following the September 14, 1994 announcement, the market price
of SDRC common stock dropped from approximately $7.625 per share to
as low as approximately $3.625.

 On November 2, 1994, KPMG Peat Marwick LLP announced that it had
resigned as SDRC's audit firm and withdrew its audit certifications
of SDRC's financial statements for 1991 through 1993 due to serious
questions as to its ability to rely on the representations of SDRC's
management.  On November 3, 1994, SDRC announced that as a result of
its outside legal counsel's ongoing investigation, its senior vice
president and chief financial officer, Ronald Hoffman, and its vice
president and controller, Richard Lajoie, left the company. On
November 4, 1994, SDRC announced the resignation of its Chairman,
President and Chief Executive Officer, Ronald Friedsam.

SDRC completed the restatement of its 1991, 1992 and 1993 annual
financial statements and its unaudited financial statements for the
first and second quarter of 1994 on January 17, 1995.  After the
restatement, 1991 revenues were $129.9 million and net income was
$9.3 million.  Previously reported 1991 revenues were $146.3 million
and net income was $17.9 million.  For the year 1992, restated
revenues were $149.0 million and net income was $9.5 million. 
Previously reported revenues for 1992 were $163.6 million and net
income was $14.5 million.  For the year 1993, restated revenues were
$147.6 million and net loss was $(11.7) million.  Previously
reported revenues for 1993 were $186.3 million and net income was
$14.3 million.

Beginning on September 15, 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, certain of its former officers and current
and former directors (the "Individual Defendants"), and its then
audit firm, KPMG Peat Marwick LLP.  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 individuals who purchased and sold SDRC common
stock in open market transactions between February 3, 1992 and
September 14, 1994.  The claims made by the plaintiffs in this case
were based on SDRC's alleged disclosures of misleading information
and failure to disclose certain adverse information arising from the
facts described above and the alleged participation of the
Individual Defendants and KPMG Peat Marwick LLP therein.  The
plaintiffs further alleged that certain of the Individual Defendants
had engaged in sales of SDRC Common Stock while in the possession of
material undisclosed information regarding SDRC ("insider trading").
The plaintiffs asserted that all of the defendants violated Section
10(b) of the Securities Exchange Act of 1934 (the "Exchange Act")
and Rule 10b-5 promulgated thereunder and that the Individual
Defendants, as controlling persons of SDRC, were also liable under
Section 20(a) of the Exchange Act and, by reason of the alleged
insider trading of certain of the Individual Defendants, were liable
under Section 20A(a) of the Exchange Act.  The plaintiffs also
relied upon theories of common law fraud.  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.  On March 22, 1996 the proposed settlement
was approved by the court and a final order was entered.  Pursuant
to the settlement, SDRC established 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).  KPMG Peat Marwick LLP provided an additional
$9.9 million cash.  The settlement does not constitute an admission
of liability on the part of any defendant.  SDRC's Board  of
Directors determined that the settlement was in the best interests
of SDRC and its shareholders in light of the uncertainty of the
outcome, the high cost of continued litigation of the matter and the
high level of management time and attention it would require which
could be better spent on SDRC's business.

The Derivative Case remains pending, but the parties have entered
into a Memorandum of Understanding for a proposed settlement,
subject to final approval of the United States District Court.  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.  For this
reason, and the cost to SDRC of continued litigation, SDRC's Board
of Directors determined that a reasonable settlement of the
Derivative Litigation would be in the best interests of SDRC and its
shareholders.  Under the proposed settlement, SDRC will pay the
plaintiffs' counsel $900,000 in legal fees and up to $50,000 for
out-of-pocket expenses.  The settlement does not constitute an
admission of liability on the part of any defendant.

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 came to an early
understanding with the primary insurer with respect to its coverage,
and has in fact received payment of the entire $5 million of such
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.  AESIC and Old Republic based their
position on numerous theories, including among others allegations
that their policies are voidable because SDRC did not disclose
alleged improper booking of sales on its application for the
insurance, that their policies do not cover pre-existing litigation
and the Class Action Case and Derivative Case included various
claims that had previously been asserted against SDRC in prior
litigation, that the matters in question are uninsurable as a matter
of law, and that coverage is not available with respect to alleged
deliberate fraudulent acts or willful violations of statutes or
regulations.  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 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 trademark of CAMAX. 

Employees

As of May 3, 1996, CAMAX had 152 employees, including 32 in sales
and marketing positions, 42 in engineering and product development,
48 in technical training and support and 30 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 an
office facility in Eugene, Oregon with 21,600 square
feet. In addition, CAMAX leases an engineering and product
development office in High Wycombe, United Kingdom.

Employment Agreement

Employment Agreement is for two years.  According to the terms of
the Employment Agreement, Mr. Winegarden is to serve as CAMAX's
Chief Technical Officer and perform such 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

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

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 May 3, 1996,
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 May
3, 1996, CAMAX had outstanding options to purchase an aggregate of
548,750 shares, at a weighted average exercise price of $.51 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 May
3, 1996, CAMAX had outstanding options to purchase an aggregate of
201,309 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 May
3, 1996, 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.  Mr. Hadley exercised his options
in April, 1996.  No other options have been granted under the
Directors' Plan.

PROFORMA FINANCIAL STATEMENTS

Proforma Combined Financial Statements

The proforma combined statement of operations for the years ended
December 31, 1993, 1994 and 1995 and the three months ended March
31, 1996 and the combined balance sheet as of March 31, 1996, give
effect to the Merger accounted for as a pooling-of-interests.  This
proforma information is based on the historical consolidated
financial statements of SDRC and CAMAX and their subsidiaries under
the assumptions and adjustments set forth in the accompanying notes
to the proforma combined financial statements.

The proforma combined financial statements have been prepared
based upon SDRC's and CAMAX's respective consolidated financial
statements.  Proforma per share amounts are based upon the exchange
ratio of .0551 shares of SDRC Common Stock for each share of CAMAX
Common Stock.  The proforma combined financial condition and results
of SDRC and CAMAX may not be indicative of the results that actually
would have occurred if the Merger had been in effect during the
periods presented or which may be attained in the future.  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 $1,882,000.  The proforma combined
financial statements should be read in conjunction with the
historical consolidated financial statements and notes thereto of
SDRC incorporated by reference herein, and of CAMAX included herein.

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 second day prior to the Mailing Date.

The proforma combined data (unaudited) for the years ended
December 31, 1993, 1994 and 1995 and the three months ended March
31, 1996 and as of March 31, 1996 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, 1993.  Following the completion of the acquisition of CAMAX and
its subsidiaries by SDRC, SDRC plans to merge CAMAX and its
subsidiaries into the SDRC operation by integrating the functional
areas as appropriate.  No proforma adjustments have been included in
the proforma financial statements to reflect potential effects of
(a) efficiencies which may be obtained by combining the CAMAX and
SDRC operations, or (b) costs of restructuring, integration or
consolidation of their operations.  The costs of integration are not
expected to have a material impact on the resultant combined
financial statements.

(2) Proforma Adjustments

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

   (a)  To record the issuance of an estimated 1,009 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 $29.75 as calculated by the average closing price of the SDRC
stock for the twenty days ending May 23, 1996.    

(b) To conform the accounting for income taxes to FAS 109 as of
January 1, 1992 and to establish a valuation allowance against the
CAMAX deferred tax assets as 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. 

(d) To record the estimated direct expenses related to the Merger
net of the amounts included in the historical financial statements.

(e) To reclassify certain long-term debt as current portion of
long-term debt due to acceleration of the payment terms with a
change in control of CAMAX.


                     DESCRIPTION OF CAPITAL STOCK

SDRC is authorized to issue 100,000,000 shares of SDRC Common
Stock, without par value.  As of April 30, 1996, SDRC had
outstanding 31,434,515  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 18,293,321 shares were issued and outstanding as of
May 23, 1996.  As of May 23, 1996, CAMAX had issued options to
purchase a total of 3,179,109 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
548,750 shares of CAMAX Common Stock had been issued pursuant to
CAMAX's 1987 Stock Option Plan at a weighted average exercise price
of $.51 per share; options to purchase 197,759 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 $.71 per share.  No additional
stock options will be permitted to be granted under CAMAX's 1985 and
1987 Stock Option Plans 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 90,000 shares of CAMAX Common Stock pursuant to CAMAX's
Directors' Plan at an exercise price of $.70 per share.  CAMAX has
also assumed non-qualified options issued by Point Control to
purchase 71,000 shares of CAMAX Common Stock at a weighted average
exercise price of $.56 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 SHAREHOLDER RIGHTS

The rights of the shareholders of SDRC are governed by the Ohio
General Corporation Law (the "OGCL"), the Articles of Incorporation
of SDRC, as amended ("SDRC Articles"), and the Amended Code of
Regulations of SDRC ("SDRC Code").  The rights of the shareholders
of CAMAX are governed by the Minnesota Business Corporation Act (the
"MBCA"), as well as by the Restated Articles of Incorporation of
CAMAX, as amended ("CAMAX Articles"), and the Bylaws of CAMAX, as
amended ("CAMAX Bylaws").  The following is a summary of certain
material differences between the rights of shareholders of SDRC and
the rights of shareholders of CAMAX, as contained in provisions of
the OGCL and the MBCA, the SDRC Articles and SDRC Code, and the
CAMAX Articles and CAMAX Bylaws.

The following does not purport to be a complete statement of the
rights of SDRC's shareholders under applicable Ohio law and the SDRC
Articles and SDRC Code as compared with the rights of CAMAX
shareholders under Minnesota law and the CAMAX Articles and CAMAX
Bylaws.  The identification of certain specific differences is not
meant to indicate that other equally or more significant differences
do not exist.

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.

Cumulative Voting  

Under Ohio law, unless the articles of incorporation are amended to
deny cumulative voting rights, each shareholder has the right to
cumulate his or her voting power.  SDRC has so amended its articles,
and the holders of SDRC Common Stock do not have the right to vote
cumulatively in the election of directors.  Under Minnesota law
cumulative voting is presumed unless denied in the Articles of
Incorporation.  The CAMAX Articles deny cumulative voting rights.

Preemptive Rights  

Under both the OGCL and the MBCA, shareholders of a corporation are
presumed to have preemptive rights unless denied in the
corporation's articles of incorporation.  The SDRC Articles and the
CAMAX Articles each deny preemptive voting rights.

Shareholders' Dissenters' Rights

Under both the OGCL and the MBCA, shareholders may exercise a right
of dissent from certain corporate actions and obtain payment of the
fair value of their shares.  This remedy is an exclusive remedy,
except where the corporate action involves fraud or illegality.

The OGCL grants such dissenters' rights to a shareholder with
respect to (i) amendments to articles of incorporation that adjust
or eliminate dividend rights or are substantially prejudicial to the
holders of shares of a class that has preference in dividends or
distributions or on liquidation over other classes (provided the
articles do not expressly or by implication permit such amendments),
(ii) a disposition of all or substantially all of the corporation's
assets not in the usual course of business, (iii) mergers if the
merger is into a surviving or new entity, (iv) mergers if the
shareholder is entitled to vote on the merger or if the merger is
the merger of a subsidiary into a parent and (v) plans of exchange
involving the acquisition of the corporation's shares if the
shareholder is entitled to vote on the plan.  

Under the MBCA, the categories of transactions subject to
dissenters' rights are similar to those in the OGCL.  A shareholder
of a Minnesota corporation may exercise dissenter's rights in
connection with an amendment to the articles of incorporation
materially and adversely affecting the rights or preferences of
shares held by the dissenting shareholder, a disposition of all or
substantially all of the corporation's property and assets not in
the usual course of business, a plan of merger in which the
shareholder may vote, and a plan of exchange involving the
acquisition of the corporation's shares if the shareholder is
entitled to vote on the plan.

Board of Directors

The OGCL provides that the number of directors of an Ohio
corporation shall not be less than three (unless all shares are
owned of record by one or two shareholders).  The SDRC Code requires
a board comprised of seven directors, which number may be increased
(to not more than 15) or decreased (to not less than seven) by the
affirmative vote of two-thirds of the board or of 80% of
shareholders entitled to vote.  In addition, the SDRC Code provides
for the division of SDRC's Board of Directors into two classes of
approximately equal size.  Directors in each class serve for two
years, and elections are staggered such that one class is elected
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 MBCA provides that the board of directors of a Minnesota
corporation shall consist of one or more directors as fixed by the
articles of incorporation or bylaws.  The CAMAX articles provide
that CAMAX shall have the number of directors, not more than nine,
as provided in the bylaws.  Under the CAMAX Bylaws, the Board of
Directors is to consist of not less than six, nor more than nine,
directors.  Each member of the CAMAX Board of Directors is to be
elected for a one-year term at the annual meeting of shareholders. 
Removal of Directors

The OGCL provides that if shareholders have a right to vote
cumulatively in the election of directors, unless otherwise provided
in the articles or code of regulations, directors may be removed by
a vote of the holders of a majority of the voting power entitled to
vote.   Under the SDRC Code, removal of a director requires the vote
of at least 80% of the voting power of the corporation entitled to
vote, voting as a single class. 

The MBCA provides that, unless modified by the articles or bylaws of
the corporation or by shareholder agreement, the directors may be
removed with or without cause by the affirmative vote of that
proportion or number of the voting power of the shares of the
classes or series the director represents which would be sufficient
to elect such director.  Under the CAMAX Bylaws, removal of a
director requires the affirmative vote of shareholders holding a
majority of the shares entitled to vote for directors.

Amendments to Bylaws

Under the OGCL and the SDRC Code, the SDRC Code may be altered,
amended, or repealed, or new bylaws adopted, by approval of the
board of directors, except that the affirmative vote of at least 80%
of the outstanding shares of SDRC entitled to vote is required to
amend SDRC Code provisions relating to special meeting requirements
and the number, term, removal and indemnification of directors.

The MBCA and the CAMAX Bylaws provide that the power to adopt, amend
or repeal the bylaws shall be vested in the board (subject to
certain notice requirements set forth in the CAMAX Bylaws), except
that the board shall not adopt, amend, or repeal a bylaw fixing a
quorum for meeting 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, under the MBCA
a shareholder or shareholders holding 3% or more of the voting
shares entitled to vote may propose a resolution to 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.

Amendments to Articles

Under the OGCL, directors may, without shareholder approval, adopt
an amendment to the articles of incorporation with respect to (i)
unissued or treasury shares (to the extent authorized by the
articles), (ii) authorization of additional shares to satisfy
previously authorized conversion or option rights and (iii)
reduction of the authorized number of shares of a class following
redemption or acquisition of shares by the corporation. 
Shareholders may adopt amendments to the articles by the affirmative
vote of two-thirds of the voting power of those shares entitled to
vote, unless the articles provide a greater or lesser proportion
(but not less than a majority).  If an amendment alters a preference
or any relative or other right of a class of outstanding shares,
then two-thirds of the shares of that class must approve the
amendment as well.  The SDRC Articles provide that any amendment to
the SDRC Articles requires the affirmative vote of two-thirds of the
voting power of the corporation.

The MBCA provides that an amendment to a corporation's articles must
be by resolution approved by the affirmative vote of a majority of
the directors present or proposed by a shareholder or shareholders
holding 3% or more of the voting shares entitled to vote thereon. 
Under the MBCA, any such amendment must be approved by the
affirmative vote of a majority of the shareholders entitled to vote
thereon, except that the articles may provide for a specified
proportion or number larger than a majority.  The CAMAX Articles do
not so provide. 

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. The MBCA allows payment of dividends if
the Board of Directors determines that the corporation will be able
to pay its debts in the ordinary course of business after paying the
dividend.  The MBCA prohibits the payment of dividends, however, if
such payment would reduce the remaining net assets of the
corporation below the aggregate preferential amount payable in the
event of liquidation to the holders of preferred stock.  Under the
OGCL, dividends may be declared and paid in cash or property only
out of the unreserved and unrestricted earned surplus of the
corporation, except that no dividends may be paid when the
corporation is insolvent or when the payment thereof would render
the corporation insolvent or when the declaration or payment thereof
would be contrary to any restriction contained in the articles of
incorporation.  Under the OGCL, dividends may be declared and paid
in the corporation's own treasury shares.  The concept of treasury
shares does not exist under the MBCA.

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.

Indemnification and Personal Liability of Directors and Officers

The SDRC Code provides for the indemnification of each director and
officer of the corporation to the fullest extent permitted by Ohio
law.  Generally, Ohio permits indemnification against all expenses
and liabilities reasonably incurred by or imposed by a person 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, 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 provided that the board or the shareholders make a
determination that the person has met the applicable standard of
conduct, 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 Bylaws provide for the indemnification of all directors
and officers of the corporation to the fullest extent permitted by
the MBCA.  Indemnification obligations under the MBCA are mandatory
with respect to all actions regardless of who brought the action,
provided that certain standards of conduct are met.  In addition,
the MBCA requires the corporation to report the indemnification
payments to its shareholders not later than the next meeting of
shareholders.  There is no similar provision in the OGCL or in the
SDRC Code.

Shareholder Right to Inspect

The OGCL provides that any shareholder, upon written demand stating
the specific purpose thereof, has the right to examine (and make
copies) in person or by agent or attorney, at any reasonable time
and for any reasonable and proper purpose, the articles of the
corporation, its regulations, its books and records of account,
minutes, shareholder records and voting trust agreements, if any, on
file with the corporation. 

Under the MBCA and the CAMAX Bylaws, every shareholder of CAMAX and
every holder of a voting trust certificate has the right, upon
written demand, to examine and copy in person or by authorized agent
or attorney records of shareholder proceedings for the prior three
years, records of board proceedings for the prior three years, CAMAX
Articles and Bylaws, financial statements required to be kept by
CAMAX, reports made to shareholders generally in the prior three
years, a statement of the names and usual business addresses of the
directors and principal officers, voting trust agreements,
shareholder control agreements and any agreements fixing the
relative rights and preferences of a class or series of capital
stock.

Shareholder Meetings

In accordance with the SDRC Code, special meetings of the
shareholders of SDRC may be called by the Board, the Chairman of the
Board, the President (in the Chairman's absence), or shareholders
holding 50% of all shares outstanding and entitled to vote thereat. 
Notice of each annual or special meeting of shareholders must be
given in writing not less than seven days before the meeting,
although shareholders may waive the notice requirements at any time. 
The OGCL also provides that if the meeting is called by a person
other than the Board and notice is not given by the corporation
within 15 days after the delivery of the request, those persons
entitled to call the meeting may give the notice. 

Under the MBCA and the CAMAX Bylaws, the Chief Executive Officer,
the Chief Financial Officer, any two directors, or one or more
shareholders holding ten percent or more of shares entitled to vote
at such meeting may call a special meeting.  However, if the meeting
involves a business combination, including an action to affect the
composition of the Board of Directors, then at least 25% of the
shares entitled to vote at such meeting are required to call the
meeting.  The CAMAX Bylaws also provide that notice of each
shareholder meeting must be mailed not less than 10 nor more than 60
days prior to the meeting, except that notice of a meeting at which
there is to be considered (i) an agreement of merger or exchange of
shares, (ii) a proposal to dispose of all or substantially all of
the property and assets of the corporation, (iii) a proposal to
dissolve the corporation, or (iv) a proposal to amend the CAMAX
Articles must be mailed to all shareholders, whether entitled to
vote or not, at least 20 days prior to the date of such a meeting. 
Under the MBCA, if the meeting is demanded by shareholders, the
meeting, on notice, must occur between 30 and 90 days after receipt
of the demand.

Fair Price Requirement for Takeover Offers

Section 302A.675 of the MBCA requires that any person who makes or
in any way participates in making a takeover offer for a publicly
held Minnesota corporation may not acquire shares of such Minnesota
corporation within two years following the last purchase of shares
pursuant to a takeover offer with respect to that class of security,
including but not limited to, acquisitions made by purchase,
exchange, merger, consolidation, partial or complete liquidation,
redemption, reverse stock split, recapitalization, reorganization,
or any other similar transaction, unless the shareholder is
afforded, at the time of the acquisition a reasonable opportunity to
dispose of the shares to the offeror upon substantially equivalent
terms as those provided in the earlier takeover offer.  These
provisions do not apply if the acquisition of shares is approved by
a committee of the board of directors' disinterested directors
before the purchase of any shares by the offeror pursuant to a
takeover offer.

While the OGCL does regulate acquisitions of Ohio corporations,
there is no comparable fair price provision in the OGCL relating to
takeover offers.

Mergers and Consolidations

In order to effect a merger under the OGCL, a corporation's board of
directors must adopt a plan of merger and recommend it to the
shareholders.  The SDRC Articles require that any merger,
consolidation or sale of all or substantially all of the
corporation's assets must be approved by the affirmative vote of the
holders of shares entitling them to two-thirds of the voting power
of SDRC.  In addition, under the OGCL any class of shares of the
corporation must approve the plan by a majority vote of the class if
the plan contains any provision which, if contained in a proposed
amendment to the corporation's articles of incorporation, would
entitle such class to vote as a class.

The MBCA provides that a resolution containing a plan of merger or
exchange must be approved by the affirmative vote of a majority of
the directors and submitted to the shareholders and approved by the
affirmative vote of a majority of the shareholders of all shares
entitled to vote.  Like the OGCL, the MBCA requires that any class
of shares of a Minnesota corporation must approve the plan if it
contains a provision which, if contained in a proposed amendment to
the corporation's articles of incorporation, would entitle such
class to vote as a class. 

Business Combinations

The OGCL bars a corporation from engaging in certain business
combinations, including mergers, dispositions of significant assets,
stock sales, recapitalizations and similar corporate control
transactions, with a shareholder of the corporation who, together
with its affiliates and associates, acquired 10% or more of the
voting power of the outstanding voting shares of the corporation
after April 11, 1990 (an "interested shareholder"), for three years
after the interested shareholder acquired the shares.  This
prohibition does not apply if the board of directors approves the
transaction prior to the acquisition of the shares by the interested
shareholder.  Further, the business combination is permitted if a
majority of the outstanding voting power not owned by or affiliated
with the interested shareholder approves the transaction no earlier
than three years after the interested shareholder acquired the
shares.  The OGCL also permits a business combination if certain
conditions are met, including, among other things, conditions with
respect to consideration to be paid in the business combination.

The MBCA contains similar restrictions on business combinations with
interested shareholders, although the restrictive period following
the acquisition date is four years as compared to the three years
under the OGCL.  In addition, Section 302A.671 of the MBCA applies,
with certain exceptions, to any acquisition of voting stock of a
corporation from a person other than the corporation, and other than
in connection with certain mergers and exchanges to which the
corporation is a party, that results in the beneficial ownership by
the acquiring party of 20% or more of the corporation's voting stock
then outstanding.  Any such acquisition must be approved by a
majority vote of the shareholders of the corporation.  In general,
in the absence of such approval, shares exceeding the threshold are
denied voting rights and may be redeemed by the corporation at their
then fair market value within 30 days after the acquiring person
fails to give a timely information statement to the corporation or
after the date the shareholders vote not to grant voting rights to
the acquiring person's shares. 

Other Anti-Takeover Provisions

In addition to the business combination statutes discussed above,
the OGCL and MBCA each contain a "control share acquisition statute"
which restricts the voting rights of a person (and those acting in
association with such person) who acquires a controlling interest in
the corporation to those voting rights which are conferred by the
shareholders of the corporation at an annual or special meeting. 
The meeting may be a scheduled meeting or a meeting called upon the
demand of the acquiring person.  In the event that the shareholders
grant voting rights to the acquiring person, the OGCL and MBCA both
provide dissenters' rights to any shareholder who did not vote in
favor of authorizing voting rights to the acquiring person. 

The MBCA provides that during any tender offer, a publicly held
corporation may not enter into or amend an agreement (whether or not
subject to contingencies) that increases the current or future
compensation of any officer or director.  Ohio law has no equivalent
provision.

It should also be noted that in addition to the anti-takeover
measures discussed above, the provisions in the SDRC Code (i)
providing for a staggered board of directors (discussed above in
"Board of Directors"), (ii)requiring a vote of two-thirds of the
shareholders to amend provisions of the SDRC Articles concerning the
election and removal of directors and concerning certain mergers,
consolidations and other business combinations and reorganizations
(discussed above under "Amendments to Articles" and "Mergers and
Consolidations"), and (iii)limiting the right of shareholders to
call a special meeting of shareholders involving a business
combination or the composition of the Board of Directors to require
the request of holders of at least 50% of the outstanding shares
(discussed above under "Shareholder Meetings") may make it more
difficult to effect a change in control of SDRC and may discourage
or deter a third party from attempting a takeover. 

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, 1993, 1994 and 1995

     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 and services.  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 March 31, 1996) 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 were $18.3 million, $17.8 million and $20.1
million in 1993, 1994 and 1995, respectively, representing a
decrease of 3% from 1993 to 1994 and an increase of 13% from 1994 to
1995.  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 $12.2
million, $11.7 million and $13.6 million in 1993, 1994 and 1995,
respectively, representing a decrease of 4% from 1993 to 1994 and an
increase of 16% from 1994 to 1995.  Substantially all of the decline
in software sales from 1993 to 1994  was due to a decrease in the
number of units of software shipped for the SmartCAM product line. 
The increase in software sales from 1994 to 1995 was due primarily
to the increase in the number of units of software shipped for
ManufacturingExpert.  CAMAX purchased the ManufacturingExpert
product line in August 1994.  Camand accounted for 50%, 50% and 44%
and SmartCAM 50%, 46% and 42% of total software sales for 1993, 1994
and 1995, respectively, and ManufacturingExpert 4% and 14% of total
software sales for 1994 and 1995, respectively.

 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.  Management expects very few 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 $4.6 million, $5.5 million and $6.4 million in 1993, 1994 and
1995, respectively, representing increases of 21% from 1993 to 1994
and 15% from 1994 to 1995.  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, 1993, 1994 and 1995, maintenance and services sales as a
percentage of total net sales accounted for 25%, 31% and 32%,
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 $1.5 million, $0.5 million and
$0.04 million in 1993, 1994 and 1995, respectively, representing
decreases of 65% from 1993 to 1994 and 93% from 1994 to 1995.  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, 1993, 1994 and 1995, other sales as a percentage of total net
sales accounted for 8%, 3%, and 0.2%, respectively.  During 1995,
CAMAX ended its practice of selling hardware products and does not
expect to generate any significant hardware sales in 1996 or future
periods.

     International Sales.  Sales outside of North America
accounted for 31%, 33% and 38% of total net sales in 1993, 1994 and
1995, respectively.  The increase in sales outside of North America
in 1994 was primarily attributable to an increase in the number of
international resellers marketing CAMAX's products.  The increase in
1995 was primarily attributable to more effective penetration of the
market across all product lines by the Company's international
resellers. 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, 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.  Costs of software sales were $0.8 million, $2.2
million and $1.5 million in 1993, 1994 and 1995, respectively,
representing 7%, 19% and 11% 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
ManufacturingExpert product line and the cost of royalties for third
party technology. The decrease from 1994 to 1995 was primarily due
to the amortization of the ManufacturingExpert product line acquired
in 1994 (See Note 2 of Notes to Consolidated Financial Statements). 


 In August 1994, CAMAX purchased the assets for the software
product known as ManufacturingExpert from Autodesk, Inc.
("Autodesk").  The purchase price was $1.6 million, which was paid
with a down payment 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 change significantly reduced the amount
of time between technological feasibility and release thereby
reducing 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 and 1995 were expensed as
incurred.  Costs of $0.5 million were capitalized in 1993.  CAMAX
estimated that such costs had an economic life of two years. 
Amortization expense of $0.4 million, $0.3 million and $0.1 million
has been included in cost of software sales for 1993, 1994 and 1995,
respectively.

Cost of Maintenance and Services Sales.  Cost of maintenance and
services sales consists primarily of the same types costs as those
incurred for software sales, as well as costs for third party
technology maintenance.  Costs of maintenance and services sales
were $0.2 million, $0.3 million and $0.4 million in 1993, 1994 and
1995, respectively, representing 3%, 6% and 7% of maintenance and
services sales for each respective year.  The increase in the cost
of maintenance and services sales in dollar amount and as a
percentage of maintenance and service 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 the
use of third party technology. 

   Cost of Other Sales.  Cost of other sales consists primarily of
the cost of third party hardware products purchased by CAMAX and
resold to its customers.  Costs of other sales were $1.1 million,
$0.4 million and $0.02 million in 1993, 1994 and 1995, respectively,
representing 69%, 66% and 70% of other sales for each respective
year.  The decrease in the dollar amount of other sales in each
successive year was due primarily to the decrease in other
sales.    


 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 $9.8
million, $10.1 million and $10.2 million, or 54%, 57% and 51% of
total net sales, in 1993, 1994 and 1995, respectively.  The
year-to-year
 increases in dollar amount were 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 markets
outside of North America.

 Research and Development.  Research and development expenses
were $3.9 million, $4.2 million and $4.0 million in 1993, 1994 and
1995, or 21%, 24% and 20% of total net sales, in 1993, 1994 and
1995, respectively.  The increase in research and development
expenses in dollar amount and as a percentage of total net sales
from 1993 to 1994 was primarily due to the previously described
change in the software development process.  The decrease in dollar
amount and as a percentage of total net sales from 1994 to 1995 was
primarily due to reductions in third party services and equipment
maintenance costs.

 General and Administrative.  General and administrative expenses
were $2.2 million, $3.1 million and $2.3 million, or 12%, 18% and
12% of total net sales, in 1993, 1994 and 1995, respectively.  The
increase in general and administrative expenses in dollar amount and
as a percentage of total net sales from 1993 to 1994 and the
decrease in dollar amount and as a percentage of total net sales
from 1994 to 1995 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 in September 1994.


    Other Expense (Income)

Other expense (income) consists of the net effect of interest
income, interest expense and miscellaneous income and expense items. 
Other expense (income) was $18,000, $26,000 and ($19,000) in 1993,
1994 and 1995, respectively.  


     Income Taxes

  The effective tax rates for 1993, 1994 and 1995 were (20%),
(2%) and 4%, respectively.  These rates differ from the statutory
rate primarily due to the use of both a net operating loss carryback
(for Point Control) and a net operating loss carryforward (for
CAMAX) in 1993, a net operating loss (consolidated) in 1994 and the
use of a net operating loss carryforward (for CAMAX) in 1995.   

 In 1993, CAMAX recognized a change in accounting for deferred
income taxes.  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, 1995, CAMAX had net operating loss
carryforwards of approximately $8.0 million, research  and
development tax credit carryforwards of approximately $0.6 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 available in the
future.  See Note 7 of Notes to Consolidated Financial
Statements.


Three Months Ended March 31, 1995 and 1996    

     Net Sales

Total net sales decreased by 12% from $4.6 million for the three
months ended March 31, 1995 to $4.1 million for the three months
ended March 31, 1996.  Total net sales decreased primarily due to a
decline in sales of software licenses for Camand and
ManufacturingExpert which was partially offset by 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 three months ended March 31, 1995
and 1996.

 Software Sales.  Sales from software licenses decreased 25% from
$3.2 million for the three months ended March 31, 1995 to $2.4
million for the three months ended March 31, 1996.  The decrease was
primarily due to a decline in sales of software licenses for Camand
and ManufacturingExpert.  The decrease for Camand was due to reduced
demand for this product line, while the decrease for
ManufacturingExpert was due to an announced termination of the
product line.  In July 1995, CAMAX announced a program to eliminate
the sale and use of the ManufacturingExpert product line. 
Management expects very few sales from the sale of software licenses
for ManufacturingExpert in 1996 and no sales in 1997 and future
periods.  In the three months ended March 31, 1995 and 1996, Camand
accounted for 48% and 43%, SmartCAM accounted for 41% and 55% and
ManufacturingExpert accounted for 11% and 2%, respectively, of total
software sales.

 Maintenance and Service Sales.  Maintenance and services sales
increased 19% from $1.4 million for the three months ended March 31,
1995 to $1.7 million for the three months ended March 31, 1996.  The
growth was primarily attributable to an increasing number of CAMAX's
customers electing to purchase software maintenance agreements.  As
percentage of total net sales, maintenance and services sales
accounted for 31% and 41% for the three months ended March 31, 1995
and 1996, respectively.

 Other Sales.  Other sales were $22,000 for the three months
ended March 31, 1995 and zero for the three months ended March 31,
1996. During 1995, CAMAX ended its practice of selling hardware
products and does not expect to generate any significant hardware
sales in 1996 or future periods.

     Cost of Sales

Cost of Software Sales.  Cost of software sales increased from
$0.3 million for the three months ended March 31, 1995 to $0.4
million for the three months ended March 31, 1996, representing 11%
and 15%, respectively, of software sales for each period.  The
increase in dollar amount  and as a percentage of software sales was
primarily due to the increase in the cost of royalties on the use of
third party technology.

 Cost of Maintenance and Service Sales.  Cost of maintenance and
service sales decreased from $0.09 million for the three months
ended March 31, 1995 to $0.04 million for the three months ended
March 31, 1996, representing 6% and 2%, respectively, of maintenance
and service sales.  The decrease in dollar amount and as a
percentage of maintenance and service sales was primarily due to the
amortization of capitalized software in 1995.

Cost of Other Sales.  Cost of other sales was $15,000 for the
three months ended March 31, 1995 and zero for the three months
ended March 31, 1996.  The decrease in dollar amount was due to the
decrease in related other sales.
  
Operating Expenses

 Sales and Marketing.  Sales and marketing expenses increased 4%
from $2.4 million for the three months ended March 31, 1995 to $2.5
million for the three months ended March 31, 1996, representing 51%
and 61%, respectively, of total net sales.  The increase in sales
and marketing expenses as a percentage of total net sales was due
primarily to the same relative level of sales and marketing expense
for each year spread over a smaller sales base in 1996 as compared
to 1995.

 Research and Development.  Research and development expenses
increased by 10% from $0.9 million for the three months ended March
31, 1995 to $1.0 million for the three months ended March 31, 1996,
representing 20% and 26%, respectively, of total net sales.  The
increase in research and development expenses in dollar amount and
as a percentage of total net sales was primarily due to increases in
the number of software engineers and computer equipment
depreciation.

General and Administrative.  General and administrative expenses
increased by 38% from $0.5 million for the three months ended March
31, 1995 to $0.7 million for the three months ended March 31, 1996,
representing 11% and 17%, respectively, of total net sales.  The
increase in dollar amount and as a percentage of total net sales was
primarily due to accounting and legal expenses associated with
CAMAX's impending acquisition by Structural Dynamics Research
Corporation.  See Note 9 of Notes to Consolidated Financial
Statements.

     Other Income (Expense)

Other income was $7,000, net, for the three months ended March
31, 1995 as compared to $14,000, net, for the three months ended
March 31, 1996.  The increase in other income was primarily due to
a reduction in interest expense. 

     Income Taxes

Income tax expense for the three months ended March 31, 1995 was
$18,000 as compared to zero for the three months ended March 31,
1996.  The decrease was due to the decrease in income before
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
1993, 1994, 1995 and the three months ended March 31, 1996, $1.1
million, $2.2 million, $2.5 million and $0.1 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 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 1993, 1994, 1995 and the three months
ended March 31, 1996, CAMAX used $0.7 million, $0.9 million, $1.9
million and $0.3 million, respectively, to purchase property and
equipment, primarily computer hardware and software.  In addition,
CAMAX capitalized software development costs of $0.5 in 1993. 
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 levels of those for 1992-1994.  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 March 31, 1996, CAMAX had $3.6 million of cash, cash
equivalents and short-term investments and $2.2 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
March 31, 1996 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 (8.25% at March 31, 1996) plus 1.625% and expires in
November 1998.  The principal balance of this term loan was $426,000
at March 31, 1996.  At March 31, 1996, CAMAX had outstanding
$387,000 in remaining obligations for installment loans and
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 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
(8.25% at March 31, 1996).  Borrowings under the $750,000 line of
credit agreement bear interest at the bank's reference rate (8.25%
at March 31, 1996) plus 1% 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 March 31, 1996, CAMAX had no borrowings outstanding under either
agreement.

CAMAX's days sales outstanding were 61, 56, 58 and 65 at December
31, 1993, 1994, 1995 and March 31, 1996, respectively.

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

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, 1994 and 1995 and the related consolidated
statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended December 31, 1995. 
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 interests as described
in Note 2 to the consolidated financial statements.  We did not
audit the statements of operations, shareholders' equity, and cash
flows of Point Control Co. for the year ended December 31, 1993,
which statements reflect total net revenues of $8,705,647.  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 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, 1994 and 1995 and the results of their operations and
their cash flows for each of the three years in the period ended
December 31, 1995, 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.

express an opinion on these financial statements based on our audit.
We conducted our audit in accordance with generally accepted

includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all
material respects, the consolidated results of operations and cash
flows of Point Control Co. and subsidiaries for the year ended
December 31, 1993, in conformity with generally accepted accounting
principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1993, 1994, AND 1995
THREE MONTHS ENDED MARCH 31, 1995 AND 1996 (UNAUDITED)

1.  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Operations:

CAMAX Manufacturing Technologies, Inc. and its wholly owned
subsidiaries, Point Control Co., Point Control International Sales
Corporation, and Point Control International Limited, (collectively,
the Company) develop and market computer software and services for
use in manufacturing facilities and distribute the products
nationally and internationally primarily through a dealer network.

The nature of the Company's operations exposes the Company to
certain business risks.  The market for computer software and
services is highly competitive and subject to rapid technological
change and evolving industry standards that may affect both the
operations of the Company and its customers.  In addition, there are
risks inherent in the Company's international business activities
such as currency fluctuations, reduced protection for intellectual
property and other such conditions which may also adversely affect
the Company's business, operating results and financial condition.

Summary of Significant Accounting Policies:

Changes in Accounting Principles - Effective January 1, 1996, the
Company adopted SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of." 
SFAS No. 121 requires impairment  losses to be recorded on
long-lived assets
 used in operations when indicators of impairment are
present and the undiscounted cash flows estimated to be generated by
those assets are less than the assets' carrying amount.  SFAS No.
121 also addresses the accounting for long-lived assets that are
expected to be disposed of.  Adoption of SFAS No. 121 did not have
a material effect on net income.

Effective January 1, 1996, the Company adopted SFAS No. 123,
"Accounting for Stock-Based Compensation."  SFAS No. 123 requires
expanded disclosures of stock-based compensation arrangements with
employees and encourages (but does not require) compensation cost to
be measured based on the fair value of the equity instrument
awarded.  Companies are permitted, however, to continue to apply
Accounting Principles Board (APB) Opinion No. 25, which the Company
presently is following and which recognizes compensation cost based
on the intrinsic value of the equity instrument awarded.  Adoption
of SFAS No. 123 did not have a material effect on net income as the
Company will continue to apply APB Opinion No. 25 to its stock-based
compensation awards to employees and directors and will disclose the
required proforma effect on net income and earnings per share in its
1996 Annual Report.

Consolidation - The consolidated financial statements include the
accounts of CAMAX Manufacturing Technologies, Inc. (formerly CAMAX
Systems, Inc.) and its subsidiaries.  All significant intercompany
accounts and transactions have been eliminated in consolidation.

Unaudited Consolidated Financial Statements - The consolidated
balance sheet as of March 31, 1996 and the statements of operations,
shareholders' equity, and cash flows for the three-month periods
ended March 31, 1995 and 1996 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.  A
substantial portion of the cash and cash equivalents are interest
bearing.

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 year 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. 
Estimated lives used in computing depreciation are as follows:

Equipment                         2 to 3 years
Office furniture and fixtures     5 years
Leasehold improvements            5 years

Capitalized lease amounts included in property were $304,000 and
$266,000, which were net of accumulated amortization of $517,000 and
$217,000, at December 31, 1994 and 1995, respectively.

Deferred Computer Software Development Costs - Under the criteria
set forth in 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
change significantly reduced the amount of time between
technological feasability and release thereby reducing 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 have been expensed as
incurred.

Costs of $483,000 were capitalized in 1993 and were included in
deferred software development costs.  The Company estimated that
such costs had an economic life of two years.  Amortization expense
of $353,000, $304,000, and $138,000 has been included in cost of
sales for 1993, 1994, and 1995, respectively.

Impairment of Long-Lived Assets - Management of the Company
periodically reviews the carrying value of long-term assets,
including 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
write-off of
 Manufacturing Expert 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%, 33%, and 38% of total net sales in 1993,
1994, and 1995, 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 the financial statements of prior years. 
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 year end
based on statutory tax rates applicable to years 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 cumulative effect
of a credit to income of $975,567 as of January 1, 1993.

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 1993 and 1994 amounts have been
reclassified to conform with presentations in the 1995 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.

Combined and separate results of CAMAX and PCC during the periods
preceding the merger were as follows:

                             CAMAX         Point
                             Systems, Inc. Control Co. Combined

Six months ended 
June 30, 1994 (unaudited):

Net revenues                 $4,775,343   $4,200,854 $ 8,976,197
Net income (loss)               (40,274)      41,255         981

Year ended December 31, 1993:

Net revenues                 $9,582,299   $8,705,647 $18,287,946
Income before cumulative
 effect of accounting change    750,244     (382,320)    367,924
Cumulative effect of 
 accounting change            1,000,000      (24,433)    975,567
Net income (loss)             1,750,244     (406,753)  1,343,491

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 Manufacturing Expert Assets:

On August 9, 1994, the Company purchased the assets for the software
product known as Manufacturing Expert 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 1995 include $506,000 and $109,000,
respectively, for these transition services.  The purchased software
was amortized completely during 1994 and 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. LINES 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, 1995).  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, 1995,
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 and restricts the
declaration of payments of dividends.

The $750,000 line of credit is collateralized with accounts
receivable, inventory, equipment, and general intangibles of the
Company.  The interest rate is variable, based on the bank's
reference rate (8.5% at December 31, 1995), plus 1%, with a floor of
8.75%.  As part of the borrowing arrangement, the Company is
required to maintain a $50,000 compensating balance.  At December
31, 1995, the Company had no borrowings outstanding under this line
of credit agreement.  In addition, the line of credit agreement
contains certain restrictive covenants which, among other things,
require the Company to maintain tangible net worth of not less than
$3,250,000 and a current ratio of not less than 1.25:1.

4. LONG-TERM DEBT

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

                                        1994      1995

                                     $1,303,718 $  879,083
                                     ==========  =========

Various loan agreements and capitalized leases are collateralized by
the pledge of certain equipment.  Total long-term debt maturities at
December 31, 1995 are approximately $769,000 in 1996, $604,000 in
1997, $201,000 in 1998, $67,000 in 1999, and $7,000 in 2000.

5.  LEASE COMMITMENTS

The Company leases its facilities and certain equipment under
operating leases with terms remaining of up to 54 months.  Rent
expense applicable to operating leases was $747,000 in 1993,
$769,000 in 1994, and $846,000 in 1995.  Future minimum lease
payments under noncancelable operating leases for the five years
ending December 31, 2000 approximate $1,593,000.  These minimum
payments are 1996, $414,000; 1997, $414,000; 1998, $353,000; 1999,
$351,000; 2000, $61,000.

8.  FAIR VALUE DISCLOSURE OF FINANCIAL INSTRUMENTS

Cash, receivables, accounts payable, accrued expenses, and other
liabilities are carried at amounts which reasonably approximate
their fair value.

The fair value estimates presented herein are based on information
available to management as of December 31, 1995.  Although
management is not aware of any factors that would significantly
affect the estimated fair value amounts, such amounts have not been
comprehensively revalued for the purposes of these financial
statements since that date, and current estimates of fair value may
differ significantly from the amounts presented therein.

                     AGREEMENT OF MERGER
                  AND PLAN OF REORGANIZATION

   This Agreement of Merger and Plan of Reorganization (the
"Agreement") made this 16th day of January, 1996 by and among CAMAX

                             THE MERGER

Section 1.1 Transfer of Property and Liabilities.  Upon the

assume and be liable for all of the liabilities, obligations and
penalties of CAMAX, in accordance with the General Corporation Law
of the State of Ohio and the Minnesota Business Corporation Act.

Section 1.2 Surviving Corporation.  Following the Merger, the
existence of Surviving Corporation shall continue unaffected and
unimpaired by the Merger, with all the rights, privileges,
immunities and powers, subject to all of the duties and liabilities
of a corporation organized under the laws of the State of Ohio.  The
Articles of Incorporation and Code of Regulations of Surviving
Corporation, as of the Effective Date, shall continue in full force

except that Article First of the Articles of Incorporation of
Surviving Corporation shall be amended in its entirety to read as

prior to the Effective Date shall continue as the officers and

Section 1.3 Principal Office.  Following the Effective Date, the
principal office of  Surviving Corporation shall be located in
Milford, Clermont County, Ohio.

State of Ohio.
Section 1.5 Registered Office.  The address, including street and

Section 1.6 Agreement with Secretary of State.  The Surviving
Corporation shall file with the Secretary of State of Minnesota an
agreement to the following effect (and if acceptable to the
Secretary of State of Minnesota, this Agreement when filed as part
of the Articles of Merger shall constitute such agreement):

Section 1.6.1 Service of Process.  The Surviving Corporation may be
served with process in Minnesota in any proceeding for the
enforcement of an obligation of the Surviving Corporation and in any
proceeding for the enforcement of the rights of a dissenting
shareholder of CAMAX against the Surviving Corporation.

Section 1.6.2 Appointment of Agent.  The Surviving Corporation
irrevocably appoints the Secretary of State of Minnesota as its

Section 1.6.3 Dissenting Shareholders.  The Surviving Corporation
will promptly pay to the dissenting shareholders of CAMAX the

the Minnesota Business Corporation Act with respect to the rights of
dissenting shareholders.


                                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 exercise of Stock Options assumed by it in accordance
with this Section 2.6 immediately after the Effective Date.

The net accounts receivable reflected on the latest balance sheet

material declared defaults currently existing, neither CAMAX nor its
Subsidiaries have received any notices of material default, and, to

Except as set forth on Schedule 3.7, all improvements owned by CAMAX
or its Subsidiaries (including buildings and other structures) on
the real estate leased by CAMAX conform in all respects to

there does not exist any condition that interferes with the economic
value or the use thereof as presently used or as presently proposed
to be used by CAMAX or its Subsidiaries.

Section 3.8 Environmental Matters.  Except as disclosed on Schedule
3.8:  (i) the property and assets of CAMAX and its Subsidiaries and
the operations conducted thereon by CAMAX and its Subsidiaries (aa)

there is no breach or violation of, or default under any material
contract, agreement or commitment, and no event has occurred which,

in order to safeguard the secrecy of all the Intellectual Property
that are considered to be trade secrets.

  (c) The conduct of the business of CAMAX and its Subsidiaries as
currently conducted does not, to CAMAX's knowledge, conflict,
misappropriate or infringe in any way with any intellectual property
right of any third party that, individually or in the aggregate, is
reasonably likely to have a Material Adverse Effect on CAMAX's
business, and there is no claim, suit, action or proceeding pending

or any intellectual property licenses conflicts or infringes in any
way with any third party's intellectual property rights, 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, there are no conflicts, misappropriations, infringements
or other violations by any third party of any of the Intellectual
Property owned by or licensed by or to CAMAX or any of its
Subsidiaries.

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

determination letters issued by the IRS within the past five years

are reasonable in light of the business of CAMAX and its
Subsidiaries and its  claims experience.  CAMAX and its Subsidiaries
have no knowledge that any insurance carriers presently providing

Subsidiary" shall mean any entity with respect to which the

Surviving Corporation in connection with their execution, delivery
and performance of this Agreement, the Certificate of Merger or the
Articles of Merger or the transactions contemplated hereby or

damages, deficiencies or costs, or has received any written claim,

party were to prevail against SDRC and/or the Surviving Corporation
would result in any expense, loss, damage, deficiency or cost, in an
aggregate cumulative amount in excess of $175,000 during the

CAMAX of any representation, warranty or covenant made by CAMAX in
this Agreement (except that any liability or potential liability

written notice thereof.

  (b) The Representatives shall have the right to adjust or settle
any claim, suit or judgment coming within the scope of this
indemnity obligation and shall have the right to control any
litigation related thereto.  Either party hereto desiring to

being handled by the other party shall have the right, at its
expense and with its counsel, to join with the other party and
participate fully in the defense of any such claim or interest.

  (c) SDRC, the Surviving Corporation and the Representatives shall
cooperate in the defense of any such claim or litigation and each
shall make available all books and records which are relevant in
connection with such claim or litigation.

  (d) Any and all amounts finally determined from time to time to be
due by reason of the indemnity obligations under Sections 10.1 and
10.2, shall be paid to SDRC or the Surviving Corporation from the
redemption by SDRC of that number of Retention Shares covering the
indemnity obligation within ten days of the amounts being finally
determined as provided in the Escrow Agreement as such term is
defined below.

  (e) SDRC and CAMAX shall appoint First Trust National Association,
Minneapolis, Minnesota (the "Escrow Agent") to hold the Retention

purposes of this Agreement.

AMENDMENT TO 
AGREEMENT OF MERGER AND
PLAN OF REORGANIZATION


This Amendment to Agreement of Merger and Plan of Reorganization
made this ____ day of April, 1996, by and among CAMAX Manufacturing
Technologies, Inc., a Minnesota corporation ("CAMAX"); Structural
Dynamics Research Corporation, an Ohio corporation ("SDRC") and SDRC
Systems, Inc., an Ohio corporation ("Surviving Corporation").

This Amendment amends that certain Agreement of Merger and Plan of
Reorganization dated January 16, 1996 (the "Merger Agreement") by
and among CAMAX, SDRC and Surviving Corporation.  All capitalized
terms not expressly defined herein will have the same meanings as
set forth in the Merger Agreement.

NOW THEREFORE, the parties hereto agree to amend the Merger
Agreement as follows:

1.  Section 2.1 is hereby amended in its entirety to read as
follows:

      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 second trading day prior to
the mailing date set forth on the proxy statement/prospectus for the
special meeting of CAMAX shareholders to be held for the purpose of
approving the Merger and Merger Agreement  (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.


2.  Section 8.1(iv) is hereby amended to read as follows:

(iv) By either SDRC and Surviving Corporation or CAMAX if the merger
contemplated by this Agreement is not fully and legally consummated
by July 31, 1996.

3. Except as amended by this Amendment, the Merger Agreement remains
in full force and effect in accordance with its terms.

4. This Amendment may be executed in two or more counterparts, each
of which shall be deemed an original but all of which shall together
constitute one and the same agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to
be executed on the day first above written.

January 16, 1996



The Board of Directors
CAMAX Manufacturing Technologies, Inc.
7851 Metro Parkway
Minneapolis, MN  55425-1528

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
$2,600,000.  The aggregate value of the consideration paid to CAMAX
shareholders and CAMAX option holders is approximately $32,600,000.

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, 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.

 (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, subdivision 1, or a disposition in dissolution

Subd. 2. Notice of action.  If a corporation calls a shareholder
meeting at which any action described in section 302A.471,
subdivision 1 is to be voted 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 a brief description of
the procedure to be followed under these sections.

Subd. 3. Notice of dissent.  If a proposed action must be approved

the proposed action a written notice of intent to demand the fair
value of the shares owned by the 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

shares or comply with any restrictions on transfer of uncertificated
shares within 30 days 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, accompanied by:

 (1) the corporation's closing balance sheet and statement of income
for a fiscal year ending not more than 16 months before the
effective date of the corporate action, together with the latest
available interim financial statements;

 (2) an estimate by the corporation of the fair value of the shares

and

  (3) a copy of section 302A.471 and this section, and a brief

paragraph (a) from a person who was not a shareholder on the date of
action dissented from was first announced to the public or who is

that date.  If the dissenter has complied with subdivisions 3 and 4,
the corporation shall forward to the 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.)

Manufacturing Technologies, Inc., a Minnesota corporation ("CAMAX"),
Structural Dynamics Research Corporation, an Ohio corporation
("SDRC"), Terrence W. Glarner and Raymond A. Lipkin, acting solely

                               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")

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

   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

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

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

                    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, Securities and Exchange
Commission File No. 333-907, pursuant to the Securities Act of 1933,
filed by Structural Dynamics Research Corporation (the "Company")
with the Securities and Exchange Commission, under which up to
2,000,000 shares of the Company's Common Stock without par value
("Common Stock") are to be registered in connection with the
proposed merger of CAMAX Technologies, Inc. ("CAMAX") with and into
a wholly-owned subsidiary of the Company (the "Merger").

We hereby consent to the filing of this opinion as Exhibit 5 and
23.5 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 Common Stock to be issued to the shareholders
of CAMAX pursuant to the Merger shall have been so issued 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,

DINSMORE & SHOHL

Structural Dynamics Research Corporation

Dear Sirs:

This opinion is rendered for use in connection with that certain 
Registration Statement on Form S-4, under the Securities Act of
1933, Securities and Exchange Commission File No. 333-907 (the
"Registration Statement") filed by Structural Dynamics Research
Corporation ("SDRC") with the Securities and Exchange Commission
pursuant to which up to 2,000,0000 shares of SDRC's Common Stock are
to be registered for purposes of the proposed merger of CAMAX
Technologies, Inc. into SDRC Systems, Inc., a wholly-owned
subsidiary of SDRC.  As counsel for SDRC, we have been requested to
render our opinion with respect to certain tax matters and
consequences of the merger transaction described in the Registration
Statement.  All capitalized terms used herein which are not defined
shall have the meanings ascribed to them in the Registration
Statement.

We hereby consent to the filing of this opinion as Exhibit 8 and
23.6 to the Registration Statement and the reference to our name in
the Registration Statement.

We have reviewed the terms of the proposed transaction as set
forth in the Merger Agreement and described in the Registration
Statement and expect, in connection with the closing of the proposed
transaction, to receive certain representations (the
"Representations") from certain executive officers of SDRC and CAMAX
and certain CAMAX shareholders, relating to various factual matters
relevant to the opinions expressed herein.

We have not independently verified the factual matters set forth
in the Representations.  This opinion is accordingly subject to our
actual receipt of the Representations.  Our opinion is further based
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.

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

1.  The merger of CAMAX with and into Acquisition Corp. 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 SDRC, Acquisition Corp.
or CAMAX as a consequence of the Merger;

3.  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 upon receipt of cash in lieu of
a fractional share of SDRC Common Stock.

4.  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;

5.  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

subject to the provisions of Section 302 of the Code.

7.  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

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

Very truly yours,
