<BR></FONT><FONT SIZE=2><B>Item 6. Indemnification of Directors and Officers.    <BR>  </B></FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;Delaware law provides for the indemnification of officers and directors in terms sufficiently broad to include indemnification under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the Securities Act. Pursuant to Section&nbsp;145 of the Delaware General Corporation Law, a corporation may indemnify an
officer or director if that person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to criminal actions or
proceedings, had no reason to believe the conduct was unlawful. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;The
Company has adopted provisions in its Bylaws which limit the liability of its directors and officers to the fullest extent permitted by Delaware law. The Company will indemnify
its directors and officers for claims against them arising out of their duties as directors or officers of the Company. Such indemnification includes any attorneys' fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid in settlement and amounts expended in seeking indemnification granted for such person under applicable law, the Bylaws or any agreement with the Company
reasonably incurred by a director or officer, provided such director or officer acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Company.
The Company may also advance expenses (including attorneys' fees) to its directors and officers relating to such claims. The Company has purchased and maintains insurance covering any liabilities
asserted against and incurred by its directors and officers acting in such capacities, whether or not the Company would have the power or obligation to indemnify such directors or officers under its
Bylaws. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The
undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report
pursuant to Section&nbsp;13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section&nbsp;15(d) of the Exchange Act) that
is incorporated by reference in this 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. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item&nbsp;6 above, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted 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 and will be governed by the final adjudication of such issue. </FONT></P>

PART I
INFORMATION REQUIRED IN THE
SECTION 10(a) PROSPECTUS
The
documents containing the information specified in Part I of Form S-8 (plan information and registrant information) will be sent or given to optionees as
specified by Rule 428(b)(1) of the Securities Act. Such documents need not be filed with the Securities and Exchange Commission (the "Commission") either as part of this Registration Statement
or as prospectuses or prospectus supplements pursuant to Rule 424 of the Securities Act. These documents, which include the statement of availability required by Item 2 of
Form S-8, and the documents incorporated by reference in this Registration Statement pursuant to Item 3 of Form S-8 (Part II hereof), taken together,
constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act.
PART II
INFORMATION REQUIRED IN THE
REGISTRATION STATEMENT
Item 3. Incorporation of Certain Documents by Reference
The following documents of MSC.Software Corporation (the "Company") filed with the Commission are incorporated herein by reference:
(a) the
Company's Annual Report on Form 10-K for the year ending December 31, 2000 (registration number 1-8722), as amended by
Form 10-K/A filed July 26, 2001;
(b) the
Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2001 and June 30, 2001;
(c) the
Company's Current Reports on Form 8-K, event dates May 2, 2001, June 15, 2001 and July 20, 2001; and
(d) The
description of the Company's Common Stock contained in its Registration Statement on Form 8-A filed with the Commission on May 22,
1996 and any amendment or report filed for the purpose of updating such description.
All
documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), prior to the
filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference into the prospectus and to be a part hereof from the date of filing of such documents. Any statement contained herein or in a document, all or a portion of which is
incorporated or deemed to be incorporated by reference herein, shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein
or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall
not be deemed, except as so modified or amended, to constitute a part of this Registration Statement.
Item 4. Description of Securities
The Company's Common Stock, par value $0.001 (the "Common Stock"), is registered pursuant to Section 12 of the Exchange Act. Therefore, the description
of the securities is omitted.

Item 5. Interests of Named Experts and Counsel
Not applicable.
Item 6. Indemnification of Directors and Officers.
Delaware law provides for the indemnification of officers and directors in terms sufficiently broad to include indemnification under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the Securities Act. Pursuant to Section 145 of the Delaware General Corporation Law, a corporation may indemnify an
officer or director if that person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to criminal actions or
proceedings, had no reason to believe the conduct was unlawful.
The
Company has adopted provisions in its Bylaws which limit the liability of its directors and officers to the fullest extent permitted by Delaware law. The Company will indemnify
its directors and officers for claims against them arising out of their duties as directors or officers of the Company. Such indemnification includes any attorneys' fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid in settlement and amounts expended in seeking indemnification granted for such person under applicable law, the Bylaws or any agreement with the Company
reasonably incurred by a director or officer, provided such director or officer acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Company.
The Company may also advance expenses (including attorneys' fees) to its directors and officers relating to such claims. The Company has purchased and maintains insurance covering any liabilities
asserted against and incurred by its directors and officers acting in such capacities, whether or not the Company would have the power or obligation to indemnify such directors or officers under its
Bylaws.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits
See the attached Exhibit Index at page 5.
Item 9. Undertakings
(a) The
undersigned registrant hereby undertakes:
(1) 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;
(ii) To
reflect in the prospectus any facts or events arising after the effective date of this 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 this Registration Statement; and
(iii) To
include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to
such information in this Registration Statement;
provided,
however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports
2
filed by the registrant with or furnished to the Commission pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
(2) That,
for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To
remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the
offering.
(b) The
undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report
pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that
is incorporated by reference in this 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.
(c) Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions described in Item 6 above, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted 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 and will be governed by the final adjudication of such issue.
