Exhibit 10

SEVERANCE COMPENSATION AGREEMENT

THIS AGREEMENT, dated as of ________, is between Structural Dynamics Research Corporation,
an Ohio corporation (the "Company") and _____________ (the "Executive").

The Company's Board of Directors has determined that it is appropriate to reinforce and encourage
the continued attention and dedication of members of the Company's management to their assigned
duties without distraction in potentially disturbing circumstances arising from the possibility of a
change in control of the Company.

This Agreement sets forth the severance compensation which the Company agrees it will pay to the
Executive if the Executive's employment with the Company terminates under one of the
circumstances described herein following a Change in Control of the Company (as defined herein).

1. 	Term.  This Agreement shall terminate, except to the extent that any obligation of the
Company hereunder remains unpaid as of such time, upon the earliest of (i)  _______ 30 of any year
after 20__, provided that either party has given at least 60 days prior written notice to the other party
of its or his intention to terminate this Agreement under this clause (i); (ii) the termination of the
Executive's employment with the Company based on death, Disability (as defined in Section 3(b))
and Retirement (as defined in Section 3(c)) or Cause (as defined in Section 3(d)) or by the Executive
other than for Good Reason (as defined in Section 3(e)); and (iii) two-years from the date of a
Change in Control of the Company if the Executive has not terminated his employment for Good
Reason as of such time.

2. 	Change in Control.  No compensation shall be payable under this Agreement unless and until
(a) there shall have been a Change in Control of the Company, while the Executive is still an
employee of the Company and (b) the Executive's employment by the Company thereafter shall have
been terminated in accordance with Section 3.  For purposes of this Agreement, a Change in Control
of the Company shall be deemed to have occurred if:

(i) 	there shall be consummated any consolidation or merger of the Company and, as a result of
such consolidation or merger (x) less than 50% of the outstanding common shares and 50% of the
voting shares of the surviving or resulting corporation are owned, immediately after such
consolidation or merger, by the owners of the Company's common shares immediately prior to such
consolidation or merger, or (y) any person (as such term is used in Section 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") shall become the beneficial
owner (within the meaning of Rule 13d-3 under the Exchange Act) of 20% or more of the surviving
or resulting corporation's outstanding common shares, or

(ii) 	any sale, lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company shall be consummated, or

(iii) 	the shareholders of the Company shall approve any plan or proposal for the liquidation or
dissolution of the Company, or

(iv) 	any person (as such term is used in Section 13(d) and 14(d)(2) of the Exchange Act) shall
become the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of 20%
or more of the company's outstanding common, or

(v) 	during any period of two consecutive years, individuals who at the beginning of such period
constitute the entire Board of Directors shall cease for any reason to constitute a majority thereof
unless the election or the nomination for election by the Company's shareholders of each new
director was approved by a vote of at least two-thirds of the directors then still in office who were
directors at the beginning of the period.

3. 	Termination Following Change in Control.

(a) 	If a Change in Control of the Company shall have occurred while the Executive is still an
employee of the Company, the Executive shall be entitled to the compensation provided in Section
4 upon the subsequent termination of the Executive's employment with the Company by the
Executive or by the Company unless such termination is as a result of (i) the Executive's death; (ii)
the Executive's Disability (as defined in Section 3(b) below); (iii) the Executive's Retirement (as
defined in Section 3(c) below); (iv) the Executive's termination by the Company for Cause (as
defined in Section 3(d) below); or (v) the Executive's decision to terminate employment other than
for Good Reason (as defined in Section 3(e) below).

(b) 	Disability.  If, as a result of the Executive's incapacity due to physical or mental illness, the
Executive shall have been absent from his duties with the Company on a full-time basis for six
months and within 30 days after written notice of termination is thereafter given by the Company
the Executive shall not have returned to the full-time performance of the Executive's duties, the
Company may terminate this Agreement for "Disability."

(c) 	Retirement.  The term "Retirement" as used in this Agreement shall mean termination by the
Company or the Executive of the Executive's employment based on the Executive's having reached
age 65 or such other age as shall have been fixed in any arrangement established with the Executive's
consent with respect to the Executive.

(d) 	Cause.  The Company may terminate the Executive's employment for Cause.  For purposes
of this Agreement only, the Company shall have "Cause" to terminate the Executive's employment
hereunder only on the basis of fraud, misappropriation or embezzlement on the part of the Executive.
Notwithstanding the foregoing, the Executive shall not be deemed to have been terminated for Cause
unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted
by the affirmative vote of not less than three-quarters of the entire membership of the Company's
Board of Directors at a meeting of the Board called and held for the purpose (after reasonable notice
to the Executive and an opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board), finding that in the good faith opinion of the Board the Executive was guilty
of conduct set forth in the second sentence of this Section 3(d) and specifying the particulars thereof
in detail.

(e) 	Good Reason.  The Executive may terminate the Executive's employment for Good Reason
at any time during the term of this Agreement.  For purposes of this Agreement "Good Reason" shall
mean any of the following (without the Executive's express written consent):

(i) 	the assignment to the Executive by the Company of duties inconsistent with the Executive's
position, duties, responsibilities and status with the Company immediately prior to a Change in
Control of the Company, or a change in the Executive's titles or offices as in effect immediately prior
to a Change in Control of the Company, or any removal of the Executive from or any failure to
reelect the Executive to any of such positions, except in connection with the termination of his
employment for Disability, Retirement or Cause or as a result of the Executive's death or by the
Executive other than for Good Reason;

(ii) 	a reduction by the Company in the Executive's base salary as in effect on the Date of
Termination;

(iii) 	any failure by the Company to continue in effect any benefit plan or arrangement (including,
without limitation, the Company's retirement plan, group life insurance plan, and medical, dental,
accident and disability plans) in which the Executive is participating at the time of a Change in
Control of the Company (or any other plans providing the Executive with substantially similar
benefits) (hereinafter referred to as "Benefit Plans"), or the taking of any action by the Company
which would adversely affect the Executive's participation in or materially reduce the Executive's
benefits under any such Benefit Plan or deprive the Executive of any material fringe benefit enjoyed
by the Executive at the time of a Change in Control of the Company;

(iv) 	any failure by the Company to continue the Executive's eligibility to participate in annual
executive bonus arrangements in which the Executive

plans or arrangements providing him with substantially similar benefits) (hereinafter referred to as
"Incentive Plans") or the taking of any action by the Company which would significantly reduce the
Executive's opportunity to earn incentive compensation which is related to performance results as
compared to performance exceptions periodically determined by the Company;

(v) 	a relocation of the Company's principal executive offices to a location outside of Cincinnati,
Ohio, or the Executive's relocation to any place other than the location at which the Executive
performed the Executive's duties prior to a Change in Control of the Company, except for required
travel by the Executive on the Company's business to an extent substantially consistent with the
Executive's business travel obligations at the time of a Change in Control of the Company;

(vi) 	any failure by the Company to provide the Executive with the number of paid vacation days
to which the Executive is entitled at the time of a Change in Control of the Company;

(vii) 	any material breach by the Company of any provision of this Agreement;

(viii) 	any failure by the Company to obtain the assumption of this Agreement by any successor or
assign of the Company; or

(ix) 	any purported termination of the Executive's employment which is not effected pursuant to
a Notice of Termination satisfying the requirements of Section 3(f), and for purposes of this
Agreement, no such purported termination shall be effective.

(f) 	Notice of Termination.  Any termination by the Company pursuant to Section 3(b), 3(c) or
3(d) shall be communicated by a Notice of Termination.  For purposes of this Agreement, a "Notice
of Termination" shall mean a written notice which shall indicate those specific termination
provisions in this Agreement relied upon and which sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's employment under the
provision so indicated.  For purposes of this Agreement, such purported termination by the Company
shall be effective without such Notice of Termination.

(g) 	Date of Termination.  "Date of Termination" shall mean (a) if this Agreement is terminated
by the Company for Disability, 30 days Notice of Termination is given to the Executive (provided
that the Executive shall not have returned to the performance of the Executive's duties on a full-time
basis during such 30-day period) or (b) if the Executive's employment is terminated by the Company
for any other reason, the date on which a Notice of Termination is given; provided that if within 30
days after any Notice of Termination is given to the Executive by the Company the Executive
notifies the Company that a dispute exists concerning the termination, the Date of Termination shall
be the date the dispute is finally

determined, whether by mutual agreement by the parties or upon final judgment, order or decree of
a court of competent jurisdiction (the time for appeal therefrom having expired and no appeal having
been perfected).

4. 	Compensation Under this Agreement.

(a) 	If within two years after a Change in Control of the Company a Notice of Termination is
given either by the Company to the Executive or by the Executive to the Company, and if such
termination is not by reason of the Executive's death, Disability or Retirement, or by the Company
for Cause, or by the Executive other than for Good Reason, the Company shall make the following
payments to the Executive:

(i) 	the full base salary to which the Executive is entitled through the Date of Termination;

(ii) 	credit for unused vacation;

(iii) 	an amount equal to the Executive's EICP Bonus Award under the Company's Executive
Incentive Compensation Plan for the fiscal year in which the Notice of Termination is given,
multiplied by the percentage determined by dividing the number of days in the Company's fiscal year
that have elapsed prior to the date on which the Notice of Termination is given by the total number
of days in such fiscal year.  As used in this clause (iii) the Executive's Annual EICP Bonus Award
means the dollar amount which would have been paid to Executive for the fiscal year in which the
Notice of Termination is given under the Company's Executive Incentive Compensation Plan, based
on the assumption that the Outstanding Level of performance would be reached by the Company and
the Executive.

(iv) 	an amount equal to two and one-half (2.5) times the sum of the Executive's annualized base
salary and EICP Bonus Award (as defined in clause (iii) above) for the year in which the Notice of
Termination is given, provided, however, that the amounts to be paid to the Executive under this
clause (iv) shall be reduced by the amounts payable to the Executive under clauses (ii) and (iii) of
this Section 4(a).

(b) 	If it is finally determined under the procedures set forth in Section 4(c) that the amount of
"excess parachute payments," if any, exceeds the Executive's "base amount" (as such terms are
defined in Section 280G of the Internal Revenue Code of 1986 (the "Code")) by more than 3 times,
the aggregate amount of the payments required to be made by the Company under clauses (iv), (iii)
and (ii) of Section 4(a)  that constitute excess parachute payments shall be reduced, in that order, to
$100 less than the largest amount that will result in no portion of such payment being subject to the
excise tax imposed by Section 4999 of the Code (the "Excise Tax").

(c) 	The Company shall notify the Executive in writing within 10 days after a Notice of
Termination is given either by the Company or the Executive, of the amount of the payments to be
made by the Company under this Agreement, together with any other payments made or to be made
by the Company to the Executive, that constitute "parachute payments" (as such terms are defined
in Section 280G of the Code) and excess parachute payments and of the amount of the reduction,
if any, required by Section 4(b).  Within 20 days after the Notice of Termination is given, the
Executive shall notify the Company in writing whether he agrees with the Company's calculation of
the amount of parachute payments and excess parachute payments, and with the amount of any
reduction.  If the Executive does not agree with the Company's calculations, the Executive shall
inform the Company of the amounts that he believes to be the correct amounts.  If the Company and
the Executive cannot agree within 30 days after the Notice of Termination is given on the amount
of the parachute payments and excess parachute payments, and on the amount of any reduction, the
calculation of such amounts (and any reduction ) shall be made by independent tax counsel selected
by the Company's independent auditors.  Such determination shall be completed within 15 days after
it is submitted to such independent tax counsel and shall be conclusive and binding on the parties.

(d) 	The amounts requires to be paid under Section 4(a), less the amount of any reduction
determined by the Company under Section 4(b) and 4(c), shall be paid by the Company to the
Executive in cash in a lump sum on the 10th day after the Date of Termination.  If it is later
determined, under the procedure set forth in Section 4(c), that the amount of any reduction is less
than that initially determined by the Company, the Company shall pay the difference to the Executive
in cash within five days after the amount of any reduction is finally determined.  If it is later
determined, under the procedures set forth in Section 4(c), that the amount of any reduction is more
than that initially determined by the Company, the Executive shall repay the difference to the
Company in cash within five days after the amount of any reduction is finally determined.

(e) 	Any payments required under this Section 4 shall be paid net of applicable federal, state and
local tax withholding.

(f)	If the Company is required to make payments to the Executive under Section 4(a), the
Company, until the earlier of (i)  one year after the Date of Termination or (ii) commencement of
full-time employment by the Executive with a new employer, shall maintain in full force and effect,
for the continued benefit of the Executive, medical and dental programs or arrangements in which
the Executive was entitled to participate immediately prior to the Date of Termination, provided that
continued participation by the Executive is possible under the general terms and provisions of such
plans and programs.

Except for the payment referred to in clause (i) of Section 4(a) none of the payments to the Executive
under this Section 4 shall be counted for the purpose of computing the Executive's benefits under
any pension, profit sharing, deferred compensation or other employee benefit plan maintained by the
Company.

(h) 	The parties acknowledge that Executive holds one or more stock purchase options granted
under the Company's 1994 Long-Term Stock Incentive Plan (the "Plan").  The individual stock
option agreements representing such options set forth the specific time periods and other terms under
which the options vest (become exercisable), subject to the overall provisions of the Plan.  Under
the last sentence of Section 5(b) of the Plan, the Compensation Committee of the Company's Board
of Directors is authorized to modify the vesting provisions of options outstanding under the Plan.
Under the authority and direction of the Compensation Committee acting under Section 5(b) of the
Plan, all options held by Executive under the Plan are hereby amended to include the following
sentence:  "Notwithstanding any other provisions of this Option, this Option shall immediately
become fully vested and exercisable as to all shares covered hereby upon the occurrence of a Change
in Control (as such term is defined in that certain Severance Compensation Agreement dated
______________  between the Company and the Optionee).  Such immediate vesting shall occur
regardless of whether the Optionee remains employed by the Company after such Change in Control
or is terminated (involuntarily or voluntarily) as a result of or following such Change in Control."
This Agreement shall constitute the instrument of amendment of all such options, and no other
documentation or action shall be required to effect such amendments.

5. 	No Obligation to Mitigate Damages; No Effect on Other Contractual Rights.

The provisions of this Agreement, and any payment provided for hereunder, shall not reduce any
amounts otherwise payable, or in any way diminish the Executive's existing rights, or rights which
would accrue solely as a result of the passage of time, under any Benefit Plan, Incentive Plan or
Securities Plan, employment agreement or other contract, plan or arrangement.

6. 	Successor to the Company.

(a) 	The Company will require any successor or assign (whether direct or indirect, by purchase,
merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the
Company, by agreement in form and substance satisfactory to the Executive, expressly, absolutely
and unconditionally to assume and agree to perform this Agreement in the same manner and to the
same extent that the Company would be required to perform it if such succession or assignment had
not taken place.  Any failure of the Company to obtain such agreement prior to the effectiveness of
any such succession or assignment shall be a material breach of this Agreement and shall entitle the
Executive to terminate the Executive's employment for Good Reason.  As used in this Agreement,
"Company" shall mean the Company as herein before defined and any successor or assign to its
business and/or assets as aforesaid which executes and delivers the agreement provided for in this
Section 6 or which otherwise becomes bound by all the terms and provisions of this Agreement by
operation of law.  If at any time during the term of this Agreement the Executive is employed by any
corporation a majority of the voting securities of which is then owned by the Company, "Company"
as used in Section 3, 4, 11 and 12 hereof shall in addition include such employer.  In such event, the
Company agrees that it shall pay or shall cause such employer to pay any amounts owed to the
Executive pursuant to Section 4 hereof.

(b) 	This Agreement shall inure to the benefit of and be enforceable by the Executive's personal
and legal representatives, executors, administrators, successors, heirs, distributees, devisees and
legatees.  If the Executive should die while any amounts are still payable to him hereunder, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the Executive's devisee, legatee, or other designee or, if there be no such designee, to
the Executive's estate.

7. 	Notice.  For purposes of this Agreement, notices and all other communications provided for
in the Agreement shall be in writing and shall be deemed to have been duly given when delivered
