INCORPORATED BY REFERENCE INTO THIS<BR>
REGISTRATION STATEMENT</B>

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On March&nbsp;22, 2002, the Registrant announced that it had appointed KPMG LLP
to replace Arthur Andersen LLP (&#147;Andersen&#148;) as the Registrant&#146;s independent
auditors. The Registrant&#146;s consolidated balance sheet as of December&nbsp;29, 2001,
and the related consolidated statements of operations, stockholders&#146; equity and
cash flows for the fiscal year ended December&nbsp;29, 2001, incorporated by
reference in this registration statement have been audited by Andersen, as
stated in its report dated March&nbsp;11, 2002, which is incorporated by reference
herein. After reasonable efforts, the Registrant has been unable to obtain
Andersen&#146;s consent to the incorporation by reference into this registration
statement of its report with respect to these financial statements. Under
these circumstances, Rule&nbsp;437a under the Securities Act of 1933, as amended
(the &#147;1933 Act&#148;), permits the Registrant to file this registration statement
without a written consent from Andersen. The absence of such consent may limit
recovery by investors on certain claims. In particular, and without
limitation, investors will not be able to assert claims against Andersen under
Section&nbsp;11 of the 1933 Act for any untrue statement of a material fact
contained in the financial statements audited by Andersen or any omission of a
material fact required to be stated therein. In addition, the ability of
Andersen to satisfy any claims (including claims arising from Andersen&#146;s
provision of auditing and other services to the Registrant) may be limited as a
practical matter due to the fact that Andersen is no longer a going concern.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law permits a corporation
to indemnify any of its directors or officers who was or is a party or is
threatened to be made a party to any third party proceeding by reason of the
fact that such person is or was a director or officer of the corporation
against expenses (including attorneys&#146; fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection
with such action, suit or proceeding, if such person acted in good faith and in
a manner such person 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 that such person&#146;s conduct was
unlawful. In a derivative action, i.e., one by or in the right of a
corporation, the corporation is permitted to indemnify any of its directors or
officers against expenses (including attorneys&#146; fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action or suit if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made if such person shall
have been adjudged liable to the corporation, unless and only to the extent
that the court in which such action or suit was brought shall determine upon
application that such person is fairly and reasonably entitled to indemnity for
such expenses despite such adjudication of liability.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VII of the Registrant&#146;s currently effective Certificate of
Incorporation eliminates the personal liability of its directors for monetary
damages for breach of fiduciary duty as a director, except for liability (i)
for any breach of the director&#146;s duty of loyalty to the corporation or its
stockholders, (ii)&nbsp;for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii)&nbsp;under Section&nbsp;174
of the Delaware General Corporation Law or (iv)&nbsp;for any transaction from which
the director derived an improper personal benefit. In addition, as permitted
by Section&nbsp;145 of the Delaware General Corporation Law, the Bylaws of the
Registrant provide that: (a)&nbsp;the Registrant is required to indemnify its
directors and officers and persons serving in such capacities in other business
entities (including, for example, subsidiaries of the Registrant) at the
Registrant&#146;s request (such directors, officers and other persons are
hereinafter referred to collectively as, &#147;Covered Persons&#148;), to the fullest
extent permitted by Delaware law, including those circumstances in which
indemnification would otherwise be discretionary; (b)&nbsp;the Registrant is
required to advance expenses, as incurred to such Covered Persons in connection
with defending a proceeding; (c)&nbsp;the indemnitee(s) of the Registrant have the
right to bring suit, and to

and (f)&nbsp;the Registrant may not retroactively amend the Bylaws indemnification
provision in a way that is adverse to such Covered Persons.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant has entered into indemnity agreements with each of its
executive officers and directors that provide the maximum indemnity allowed to
officers and directors by Section&nbsp;145 of the Delaware General Corporation Law
and the Bylaws, as well as certain additional procedural protections. The
Registrant also maintains a limited amount of director and officer insurance.
The indemnification provision in the Bylaws, and the indemnity agreements
entered into between the Registrant and its officers or directors, may be
sufficiently broad to permit indemnification of the Registrant&#146;s officers and
directors for liability arising under the 1933 Act.

period in which offers or sales are being made, a post-effective amendment to
this Registration Statement (i)&nbsp;to include any prospectus required by Section
10(a)(3) of the 1933 Act; (ii)&nbsp;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)&nbsp;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; <I>provided however</I>, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those clauses is contained in periodic reports filed with or
furnished to the Commission by the Registrant pursuant to Section&nbsp;13 or Section
15(d) of the Securities Exchange Act of 1934, as amended (the &#147;1934 Act&#148;), that
are incorporated by reference into this Registration Statement; (2)&nbsp;that for
the purpose of determining any liability under the 1933 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 <I>bona fide </I>offering thereof, and
(3)&nbsp;to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold upon the termination of the
offering under the Plan.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant&#146;s
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that
is incorporated by reference into 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 <I>bona fide </I>offering thereof.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the 1933 Act
may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnity provisions incorporated by reference in
Item&nbsp;6, or otherwise, the Registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in
the 1933 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 1933
Act and will be governed by the final adjudication of such issue.

         We refer to the registration statement on Form S-8 (the "Registration
Statement"), under the Securities Act of 1933, as amended (the "Securities
Act"), filed by Cadence Design Systems, Inc., a Delaware corporation (the
"Company"), with respect to the proposed offering by the Company of up to 66,795
shares (the "Shares") of its common stock, $0.01 par value per share (the
"Common Stock"), subject to issuance by the Company upon exercise of options
granted under the Neolinear, Inc. 2004 Stock Option Plan (the "Plan"). The
options issuable under the Plan were assumed by the Company pursuant to the
terms of that certain Agreement and Plan of Merger, dated as of February 19,
2004, by and among the Company, Project Hilton, Inc., a Delaware corporation and
wholly owned subsidiary of the Company, Neolinear, Inc., a Delaware corporation,
Mark Cipriano, as Stockholder Agent, and Thomas Beckley, as Earnout Stockholder
Agent.

         We have examined the originals or certified copies of such corporate
records, certificates of officers of the Company and/or public officials and
such other documents, and have made such other factual and legal investigations,
as we deemed relevant and necessary as the basis for the opinions set forth
below. In such examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, the conformity
to original documents of all documents submitted to us as conformed or
photostatic copies and the authenticity of the originals of such copies.

         Based on our examination mentioned above, subject to the assumptions
stated above and relying on the statements of fact contained in the documents
that we have examined, we are of the opinion that (i) the issuance by the
Company of the Shares has been duly authorized and (ii) when issued in
accordance with the terms of the Plan, the Shares will be duly and validly
issued, fully paid and non-assessable shares of Common Stock.

         We are admitted to practice in the State of California, and are not
admitted to practice in the State of Delaware. However, for the limited purpose
of our opinions set forth above, we are generally familiar with the General
Corporation Law of the State of Delaware (the "DGCL") as presently in effect and
have made such inquiries as we consider necessary to render this opinion with
respect to a Delaware corporation. This opinion letter is limited to the DGCL,
as it presently exists and to the facts as they presently exist. We express no
opinion with respect to the effect or applicability of the laws of any other
jurisdiction. We assume no obligation to revise or supplement this opinion
letter should the laws of such jurisdictions be changed after the date hereof by
legislative action, judicial decision or otherwise.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. In giving this consent, we do not admit that we are
within the category of persons whose consent is required under Section 7 of the
Securities Act or the General Rules and Regulations of the Securities and
Exchange Commission.



                                       Very truly yours,

                                       /s/ GIBSON, DUNN & CRUTCHER LLP

                                 NEOLINEAR INC.
                             2004 STOCK OPTION PLAN

1.       PURPOSE OF THE PLAN.

         The purpose of the Neolinear, Inc. 2004 Stock Option Plan (the "Plan")
is to promote the interests of Neolinear, Inc. (the "Company"), its
subsidiaries and its stockholders by (i) attracting and retaining employees,
officers, directors, consultants and advisors of outstanding ability, (ii)
motivating such persons, by means of performance-related incentives, to achieve
long-range performance goals, and (iii) enabling such persons to participate in
the long-term growth and financial success of the Company and its subsidiaries.
The effective date of the Plan is February 3, 2004 ("Effective Date"). For
purposes of this Plan, "subsidiary" shall mean any company (whether a
corporation, partnership, joint venture or other form of entity) in which the
Company, or a corporation in which the Company owns a majority of the shares of
capital stock, directly or indirectly, owns an equity interest of more than
fifty percent (50%).

2.       ADMINISTRATION.

         (a)      Subject to the following paragraph, the Plan shall be
administered by the Company's Board of Directors (the "Board") or by a
Committee of the Board (the "Committee"). If the Board appoints a Committee,
such Committee shall be deemed to have been delegated the authority to
administer the Plan (unless the Board determines otherwise), and shall be
empowered to take all actions reserved to the Board under the Plan. The Board
is authorized to interpret the Plan, to prescribe, amend and rescind rules and
regulations to further the purposes of the Plan, and to make all other
determinations necessary for the administration of the Plan. All such actions
by the Board shall be conclusive, final and binding on all recipients of grants
hereunder ("participants").

         (b)      Any Committee to which Plan administration is delegated
shall consist solely of Board members who qualify as (i) "Non-Employee
Directors" as defined under Rule 16b-3 under the Security and Exchange Act of
1934 and (ii) "outside directors" as defined under Section 162(m) or any
successor provision of the Code and applicable Treasury regulations thereunder,
if and to the extent such qualification is necessary so that grants made under
the Plan or the exercise of rights thereunder will qualify for any tax or other
material benefit to participants or the Company and its subsidiaries under
applicable law.

3.       GRANTS.

         Grants under the Plan shall be in the form of non-qualified stock
options ("Options").

4.       SHARES SUBJECT TO THE PLAN.

         Subject to adjustment as provided in Section 9, the maximum aggregate
number of shares of Common Stock that may be subject to grants made under the
Plan is 610,000 shares. The Common Stock to be offered under the Plan shall be
authorized and unissued Common Stock or issued Common Stock that shall have
been reacquired by the Company and held in its treasury. The Common Stock
covered by any unexercised portion of terminated stock options granted under
the Plan may again be subject to new grants under the Plan. In the event the
purchase price of an Option is paid in whole or in part through the delivery of
Common Stock, only the net number of shares of Common Stock issuable in
connection with the exercise of the Option shall be counted against the number
of shares remaining available for grant under the Plan.
<PAGE>

5.   PARTICIPANTS.

     The Board shall determine and designate from time to time those employees,
directors, consultants and advisors of the Company or its subsidiaries who
shall be granted Options under the Plan and the number of shares of Common
Stock to be covered by each such Option provided, that any such consultants or
advisors who receive grants under the Plan render bona fide services to the
Company or its subsidiaries that are not in connection with the offer or sale
of securities in a capital-raising transaction. In making its determinations,
the Board shall take into account the present and potential contributions of
the respective individuals to the success of the Company and its subsidiaries
and such other factors as the Board shall deem relevant in connection with
accomplishing the purposes of the Plan. Each grant shall be evidenced by a
written agreement or grant form ("Grant Agreement") as the Board shall approve
from time to time.

6.   FAIR MARKET VALUE.

     For all purposes under the Plan, the term "Fair Market Value" shall mean,
as of any applicable date, (i) if the principal securities market on which the
Common Stock is traded is a national securities exchange or The Nasdaq National
Market ("NNM"), the closing price of the Common Stock on such exchange or NNM,
as the case may be, or if no sale of the Common Stock shall have occurred on
such date, on the next preceding date on which there was a reported sale; (ii)
if the Common Stock is not traded on a national securities exchange or NNM, the
closing price on such date as reported by The Nasdaq SmallCap Market, or if no
sale of the Common Stock shall have occurred on such date, on the next
preceding date on which there was a reported sale; (iii) if the principal
securities market on which the Common Stock is traded is not a national
securities exchange, NNM or The Nasdaq SmallCap Market, the average of the bid
and asked prices reported by the National Quotation Bureau, Inc.; or (iv) if
the price of the Common Stock is not so reported, the Fair Market Value of the
Common Stock as determined in good faith by the Board.

7.   GRANTS OF OPTIONS.

     (a)  Exercise Price of Options.  Nonqualified Options shall be granted at
an exercise price as determined in each case by the Board and in no event shall
be less than 100% of the Fair Market Value of the Common Stock as of the date
the Options are granted.

     (b)  Terms and Termination of Options.

          (1) The Board shall determine the term within which each Option may
be exercised, in whole or in part.

          (2) Unless otherwise determined by the Board, all rights to exercise
vested Options shall terminate on the first to occur of (i) the scheduled
expiration date as set forth in the applicable Grant Agreement, (ii) 90 days
following the date of termination of employment for any reason other than the
participant's death or permanent disability (as defined in Code Section
22(e)(3)), (iii) 1 year following the date of termination of employment or
provision of services by reason of the participant's death or permanent
disability (as defined in Code Section 22(e)(3)), or (iv) as may be otherwise
provided in the event of a Change of Control as defined in Section 10;
provided, however, that in the event that a participant ceases to be employed
by or to provide services to the Company or a subsidiary due to a termination
for "cause" (as defined in Section 7(b)(3)), all rights to exercise vested
Options held by such participant shall terminate immediately.

<PAGE>
as of the date such participant ceases to be employed by or to provide services
to the Company or a subsidiary. Unless otherwise determined by the Board,
vesting of Options ceases immediately upon termination of employment for any
reason, and any portion of an Option that has not vested on or before the date
of such termination is forfeited on such date. For purposes of this Plan,
unless otherwise determined by the Board, an individual who ceases to be
employed by the Company or a subsidiary as the result of a business transaction
(other than a Change of Control as defined in Section 10), including without
limitation a sale of stock or assets, corporate reorganization, or spinoff,
shall be deemed to have incurred a termination of employment under (ii) above
without regard to whether such individual continues, following the closing of
such transaction, to be employed by or to perform services for any successor
entity or business.

          (3)   As used in this Plan, the term "cause" shall mean (i) "cause" as
defined in any applicable employment or services agreement between the Company
and a participant for purposes of determining whether a termination of such
agreement is for cause or (ii) in the absence of such agreement, a determination
by the Board that the participant has engaged in fraudulent, disloyal, or
criminal conduct injurious to the Company or any of its subsidiaries, including,
without limitation, embezzlement, theft, commission of a felony or dishonesty in
the course of his or her employment or service, the disclosure of trade secrets
or confidential information of the Company or its subsidiaries to persons not
entitled to receive such information, or breach of any noncompetition or
nonsolicitation covenant between the participant and the Company or a
subsidiary.

     (c)  Payment for Shares.  Full payment for shares purchased upon exercise
of Options granted under the Plan shall be made at the time the Options are
exercised in whole or in part. Payment of the purchase price shall be made in
cash or in such other form as the Board may approve, including, without
limitation, (i) by the participant's delivery to the Company of shares of Common
Stock that have been held by the participant for at least six months prior to
exercise of the Options, valued at Fair Market Value of such shares on the date
of exercise, (ii) if the Common Stock is publicly traded, pursuant to a cashless
exercise arrangement with a broker on such terms as the Board may determine; or
(iii) by any combination of such methods of payment. No shares of Common Stock
shall be issued to the participant until such payment has been made, and a
participant shall have none of the rights of a stockholder with respect to
Options held by such participant.

     (d)  Other Terms and Conditions.  The Board shall have the discretion to
determine terms and conditions, consistent with the Plan, which will be
applicable to Options, including, without limitation, performance-based criteria
for acceleration of the date on which certain Options shall become exercisable.
Options granted to the same or different participants, or at the same or
different times, need not contain similar provisions.

8.   ADJUSTMENTS TO REFLECT CAPITAL CHANGES.

     The number and kind of shares subject to outstanding grants, the exercise
price applicable to Options previously granted, and the number and kind of
shares available subsequently to be granted under the Plan shall be
appropriately adjusted to reflect any stock dividend, stock split, combination
or exchange of shares or other change in capitalization with a similar
substantive effect upon the Plan or grants under the Plan. The Board shall have
the power and sole discretion to determine the nature and amount of the
adjustment to be made in each case. The adjustment so made shall be final and
binding on all participants.

<PAGE>
9.       DEFINITION OF CHANGE OF CONTROL.

         For purposes of this Plan, a "Change of Control" shall mean the
occurrence of any of the following events:

         (a)      the acquisition (other than solely from the Company) by any
individual, entity or group (within the meaning of Section 13(d)(3) or Section
14(d)(2) of the Exchange Act), other than the Company or any subsidiary,
affiliate (within the meaning of Rule 144 under the Securities Act of 1933, as
amended) or employee benefit plan of the Company, of beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of more
than 50% of the combined voting power of the then outstanding voting securities
of the Company entitled to vote generally in the election of directors (the
"Voting Securities"); or

         (b)      a reorganization, merger, consolidation, share exchange or
recapitalization of the Company (a "Business Combination"), other than a
Business Combination in which more than 50% of the combined voting power of the
outstanding voting securities of the surviving or resulting entity immediately
following the Business Combination is held by the persons who, immediately prior
to the Business Combination, were the holders of the Voting Securities; or

         (c)      a complete liquidation or dissolution of the Company, or a
sale of all or substantially all of the Company's assets.

10.      CONSEQUENCES OF A CHANGE OF CONTROL.

         (a)      As determined in its discretion by the Board, upon a Change
of Control, any or all of the following may occur with respect to any or all of
the then-outstanding Options; (i) such Options shall be assumed by the
Acquiring Corporation (as defined below) or parent thereof on terms approved by
the Board or replaced with a comparable option or right to purchase shares of
the capital stock, or equity equivalent instrument, of the Acquiring
Corporation or parent thereof, or other comparable rights, in each case on
terms approved by the Board (such assumed and comparable options and rights,
together, the "Replacement Options"); (ii) all or a specified percentage of the
outstanding Options which have been granted under the Plan and which are not
exercisable as of the effective date of the Change of Control shall
automatically accelerate and become exercisable immediately prior to the
effective date of the Change of Control; (iii) in lieu of the issuance of
Replacement Options, holders of outstanding Options which are exercisable
immediately prior to a Change of Control (including those that become
exercisable under this Section 10(a)) may be required to surrender them in
exchange for a payment by the Company, in cash or Common Stock as determined by
the Board, of an amount equal to the amount (if any) by which the then Fair
Market Value of Common Stock subject to unexercised Options exceeds the
exercise price of those Options, with such payment to take place as of the date
of the Change of Control or such other date as the Board may prescribe; or (iv)
Options which are not exercised prior to the date specified in a notice to
Participants in advance of the Change of Control shall be terminated. The term
"Acquiring Corporation" means the surviving, continuing, successor or
purchasing corporation, as the case may be.

         (b)      Any Options that are not assumed or replaced by Replacement
Options, exercised, or cashed out prior to or concurrent with a Change of
Control (including, without limitation, any Options that are not exercisable as
of the effective date of the Change of Control) will terminate effective upon
the Change of Control or at such other time as the Board deems appropriate,
unless otherwise expressly provided in any applicable Grant Agreement.
<PAGE>
     (c)  Notwithstanding anything in the Plan to the contrary, in the event of
a Change of Control, no actions described in the Plan (including, without
limitation, actions described in subsections (a) and (b) above) shall be taken
if such action would make the Change of Control ineligible for desired
accounting or tax treatment if, in the absence of such actions, the Change of
Control would qualify for such treatment and the Company intends to use such
treatment with respect to such Change of Control.

11.  TRANSFERABILITY OF OPTIONS.

     Unless otherwise determined by the Board, Options granted under the Plan
shall not be transferable other than by will or the laws or descent and
distribution and are exercisable during a participant's lifetime only by the
participant.

12.  WITHHOLDING.

     The Company shall have the right to deduct any taxes required by law to be
withheld in respect of grants under the Plan from amounts paid to a participant
in cash as salary, bonus or other compensation. In the Board's discretion, a
participant may be permitted to elect to have withheld from the shares
otherwise issuable to the participant, or to tender to the Company, a number of
shares of Common Stock the aggregate Fair Market Value of which does not exceed
the minimum required withholding rate for federal (including FICA), state and
local tax liabilities. Any such election must be in a form and manner
prescribed by the Board.

13.  CONSTRUCTION OF THE PLAN.

     The validity, construction, interpretation, administration and effect of
the Plan and of its rules and regulations, and rights relating to the Plan,
shall be determined solely by the Board. Any determination by the Board shall
be final and binding on all participants. The Plan shall be governed in
accordance with the laws of the State of Delaware, without regard to the
conflict of law provisions of such laws.

14.  NO RIGHT TO GRANT; NO RIGHT TO EMPLOYMENT.

     No person shall have any claim of right to be granted an Option under the
Plan. Neither the Plan nor any action taken hereunder shall be construed as
giving any employee any right to be retained in the employ of the Company or
any of its subsidiaries or as giving any consultant, advisor or director of the
Company or any of its subsidiaries any right to continue to serve in such
capacity.

15.  GRANTS NOT INCLUDABLE FOR BENEFIT PURPOSES.

     Income recognized by a participant pursuant to the provisions of the Plan
shall not be included in the determination of benefits under any employee
pension benefit plan (as such term is defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974) or group insurance or other benefit
plans applicable to the participant which are maintained by the Company or any
of its subsidiaries, except as may be specifically provided under the terms of
such plans or determined by resolution of the Board.



<PAGE>

16.      NO STRICT CONSTRUCTION.

         No rule of strict construction shall be implied against the Company,
the Board or any other person in the interpretation of any of the terms of the
Plan, any grant made under the Plan or any rule or procedure established by the
Board.

17.      CAPTIONS.

         All Section headings used in the Plan are for convenience only, do not
constitute a part of the Plan, and shall not be deemed to limit, characterize
or affect in any way any provisions of the Plan, and all provisions of the Plan
shall be construed as if no captions had been used in the Plan.

18.      SEVERABILITY.

         Whenever possible, each provision in the Plan and every grant under
the Plan shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of the Plan or any grant under the Plan
shall be held to be prohibited by or invalid under applicable law, then such
provision shall be deemed amended to accomplish the objectives of the provision
as originally written to the fullest extent permitted by law, and all other
provisions of the Plan and every other grant under the Plan shall remain in
full force and effect.

19.      LEGENDS.

         All certificates for Common Stock delivered under the Plan shall be
subject to such transfer and other restrictions as may be provided under the
Plan or the applicable Grant Agreement or as the Board may deem advisable under
the rules, regulations and other requirements of the Securities and Exchange
Commission, any stock exchange or quotation system upon which the Common Stock
is then listed or quoted and any applicable federal or state securities laws,
and the Board may cause a legend or legends to be put on any such certificates
to make appropriate references to such restrictions.

20.      AMENDMENT.

         The Board may, by resolution, amend or revise the Plan, except that
such action shall not be effective without stockholder approval if such
stockholder approval is required to maintain the compliance of the Plan and/or
grants made to directors, executive officers or other persons with Rule 16b-3
promulgated under the Exchange Act or any successor rule. The Board may not
modify any Options previously granted under the Plan in a manner adverse to the
holders thereof without the consent of such holders, except in accordance with
the provisions of Section 8, 10 or 21.

21.      MODIFICATION FOR GRANTS OUTSIDE THE U.S.

         The Board may, without amending the Plan, determine the terms and
conditions applicable to grants of Options to participants who are foreign
nationals or employed outside the United States in a manner otherwise
inconsistent with the Plan if the Board deems such terms and conditions
necessary in order to recognize differences in local law or regulations, tax
policies or customs.
<PAGE>

22.  EFFECTIVE DATE; TERMINATION OF PLAN.

     The Plan's Effective Date is February 3, 2004. The Plan shall terminate on
February 2, 2014, unless it is earlier terminated by the Board. Termination of
the Plan shall not affect previous grants under the Plan.
