<P>&#9;The Registrant's certificate of incorporation, as amended, provides that, to the fullest extent permitted by Delaware law, as
the same now exists or may hereafter be amended, a director shall not be personally liable to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Delaware law provides that directors of a corporation will not be
personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:</P>

<UL>
<LI>for any breach of their duty of loyalty to the corporation or its stockholders,</LI>
<LI>for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law,</LI>
<LI>for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware
General Corporation Law, or</LI>

<LI>for any transaction from which the director derived an improper personal benefit.</LI></UL>


<P>&#9;The Registrant's certificate of incorporation, as amended, further provides that to the fullest extent permitted by law, the
Registrant may indemnify any person made or threatened to be made a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director, officer or employee
of the corporation or any predecessor of the corporation or serves or served at any other enterprise as a director, officer or
employee at the request of the corporation or any predecessor to the corporation.</P>

<P>&#9;The Registrant's bylaws, as amended, provide that its directors, officers and agents shall be indemnified against expenses
including attorneys' fees, judgments, fines and settlements actually and reasonably incurred in connection with any proceeding
arising out of their status as such, if such director, officer or agent acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the Registrant, and, with the respect to any criminal action or proceeding,
had no reasonable cause to believe such conduct was unlawful.</P>

<P>&#9;The Registrant has entered into agreements to indemnify its directors and officers, in addition to the indemnification
provided for in its certificate of incorporation, as amended, and bylaws, as amended. These agreements, among other things, indemnify
the Registrant's directors and officers for certain expenses, including attorneys' fees, judgments, fines and settlement amounts
incurred by any such person in any action or proceeding, including any action by or in the right of the Registrant, arising out of
such person's services as a director or officer of the Registrant, any subsidiary of the Registrant, or any other company or

<OL>



<OL>

<LI>To file, during any period in which offers or sales are being made, a post-effective amendment to this registration
statement:


<p>(i) To include any prospectus required by section 10(a)(3) of the Securities Act;</p>
<P>(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most

<P>(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.</P></LI>

<I><P>Provided, however</I>, 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 filed by the Registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.</P>
<LI><p>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.</p></LI>
<LI><p>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.</P></LI></OL>


</OL>





<LI><p>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 section&nbsp;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 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.</p></LI>
<LI><p>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 foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Commission such indemnification is against public policy as expressed in the 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 of whether such indemnification by it is against public policy as expressed in the Act and will be governed
by the final adjudication of such issue.</p></LI>

PART II
Information Required In the Registration Statement
Item 3.	Incorporation of Documents by Reference.
The following documents filed by Rational Software Corporation (the "Registrant") with the Securities and Exchange Commission
(the "Commission") are incorporated herein by reference:
The Registrant's Annual Report on Form 10-K for the year ended March 31, 2001 as filed with the Commission;
(i) The Registrant's Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2001 as filed with the Commission;
(ii) The Registrant's Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2001 as filed with the
Commission;
(iii) The Registrant's Current Report on Form 8-K dated April 5, 2001 as filed with the Commission; and
The description of the Registrant's common stock contained in the Registration Statement on Form 8-A dated May 25, 1984, as
amended on May 25, 1995, as filed with the Commission pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and any amendment or report filed for the purpose of updating such description.
All documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to
the filing of a post-effective amendment to the registration statement which indicates that all of the shares of common stock offered
have been sold or which deregisters all of such shares then remaining unsold, shall be deemed to be incorporated by reference in the
registration statement and to be a part hereof from the date of the filing of such documents; except as to any portion of any future
annual or quarterly report to stockholders or document that is not deemed filed under such provisions.  For the purposes of this
registration statement, any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded 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 of supersedes such statement.  Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to constitute a part of this registration statement.
Item 4.	Description of Securities.
Not applicable.
Item 5.	Interests of Named Experts and Counsel.
Not applicable.
Item 6.	Indemnification of Directors and Officers.
The Registrant's certificate of incorporation, as amended, provides that, to the fullest extent permitted by Delaware law, as
the same now exists or may hereafter be amended, a director shall not be personally liable to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Delaware law provides that directors of a corporation will not be
personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability:
for any breach of their duty of loyalty to the corporation or its stockholders,
for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law,
for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware
General Corporation Law, or
II-1
for any transaction from which the director derived an improper personal benefit.
The Registrant's certificate of incorporation, as amended, further provides that to the fullest extent permitted by law, the
Registrant may indemnify any person made or threatened to be made a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director, officer or employee
of the corporation or any predecessor of the corporation or serves or served at any other enterprise as a director, officer or
employee at the request of the corporation or any predecessor to the corporation.
The Registrant's bylaws, as amended, provide that its directors, officers and agents shall be indemnified against expenses
including attorneys' fees, judgments, fines and settlements actually and reasonably incurred in connection with any proceeding
arising out of their status as such, if such director, officer or agent acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the Registrant, and, with the respect to any criminal action or proceeding,
had no reasonable cause to believe such conduct was unlawful.
The Registrant has entered into agreements to indemnify its directors and officers, in addition to the indemnification
provided for in its certificate of incorporation, as amended, and bylaws, as amended. These agreements, among other things, indemnify
the Registrant's directors and officers for certain expenses, including attorneys' fees, judgments, fines and settlement amounts
incurred by any such person in any action or proceeding, including any action by or in the right of the Registrant, arising out of
such person's services as a director or officer of the Registrant, any subsidiary of the Registrant, or any other company or
enterprise to which the person provides services at the Registrant's request.

(1)	Incorporated by reference from the Registrant's Registration Statement on Form S-8 as filed with the Commission on
January 22, 1999 (File No. 333-70989).
Item 9.	Undertakings.
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;
(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;
II-2
(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.
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 filed by the Registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.
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.
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.
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 section 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 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.
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 foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Commission such indemnification is against public policy as expressed in the 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 of whether such indemnification by it is against public policy as expressed in the Act and will be governed
by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has
reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Cupertino, State of California, on
January 29, 2002.
