ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Delaware General Corporation Law (the "DGCL") permits Delaware
corporations to eliminate or limit the monetary liability of directors for
breach of their fiduciary duty of care, subject to certain limitations. The
Registrant's Restated Certificate of Incorporation provides that the
Registrant's directors are not liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the Registrant
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) for willful
or negligent violation of the laws governing the payment of dividends or the
purchase or redemption of stock or (iv) for any transaction from which a
director derived an improper personal benefit.

         The DGCL provides for indemnification of directors, officers, employees
and agents subject to certain limitations. The Registrant's Amended By-Laws and
the appendix thereto provide for the indemnification of directors, officers,
employees and agents of the Registrant to the extent permitted by Delaware law.
The Registrant's directors and officers are insured against certain liabilities
for actions taken in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "1933 Act").

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 1933 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 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 by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) 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 bona fide offering thereof; and (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 Istari 1997 Stock
Option Plan.

         B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant'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 bona
fide offering thereof.

     C. 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 indemnification provisions summarized in Item 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.

         Re: Conexant Systems, Inc. - Registration Statement on Form S-8

Dear Ladies and Gentlemen:

         We have acted as counsel to Conexant Systems, Inc., a Delaware
corporation (the "Company"), in connection with the registration on Form S-8
(the "Registration Statement") under the Securities Act of 1933, as amended, of
14,892 shares of the Company's common stock (the "Shares") for issuance under
the Istari Design, Inc. 1997 Stock Option Plan, as amended (the "Istari Plan").
The Istari Plan, together with the outstanding options under that plan, has been
assumed by the Company in connection with the Company's acquisition of Istari
Design, Inc.

         This opinion is being furnished in accordance with the requirements of
Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.

         We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the assumption of the Istari
Plan and the outstanding options thereunder. Based on such review, we are of the
opinion that if, as and when the Shares are issued and sold (and the
consideration therefor received) pursuant to the provisions of the stock option
agreements for the outstanding options under the Istari Plan assumed by the
Company and in accordance with the Registration Statement, such Shares will be
duly authorized, legally issued, fully paid and nonassessable.

         We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement.

         This opinion letter is rendered as of the date first written above and
we disclaim any obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinion expressed herein. Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company, the
assumed Istari Plan or the Shares issuable under such plan.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         (a) TERM. No Option shall be exercisable after the expiration of ten
(10) years from the date it was granted.

         (b) PRICE. The exercise price of each Incentive Stock Option shall be
not less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted; the exercise price of
each Nonstatutory Stock Option shall be not less than eighty-five percent (85%)

                                       8

<PAGE>   9

date the Option is granted. Notwithstanding the foregoing, an Option (whether an
Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an
exercise price lower than that set forth in the preceding sentence if such
Option is granted pursuant to an assumption or substitution for another option
in a manner satisfying the provisions of Section 424(4) of the Code.

         (c) CONSIDERATION. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board at the time the Option is granted, (A) by delivery
to the Company of other common stock of the Company, (B) according to a deferred
payment or other arrangement (which may include, without limiting the generality
of the foregoing, the use of other common stock of the Company) with the person
to whom the Option is granted or to whom the Option is transferred pursuant to
subsection 6(d), or (C) in any other form of legal consideration that may be
acceptable to the Board.

         In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

         (d) TRANSFERABILITY. An Option granted under the Plan prior to the
Listing Date shall not be transferable except by will or by the laws of descent
and distribution, and shall be exercisable during the, lifetime of the person to
whom the Option is granted only by such person. A Nonstatutory Stock Option
granted after the Listing Date shall only be transferable by the Optionee upon
such terms and conditions as are set forth in the Option Agreement for such
Nonstatutory Stock Option, as the Board shall determine in its discretion. The
person to whom


                                       9

<PAGE>   10

the Option is granted may, by delivering written notice to the Company, in a
form satisfactory to the Company, designate a third party who, in the event of
the death of the Optionee, shall thereafter be entitled to exercise the Option.

         (e) VESTING. The total number of shares of stock subject to an Option
may, but need not, be allotted in periodic installments (which may, but need
not, be equal). The Option Agreement may provide that from time to time during
each of such installment periods, the Option may become exercisable ("vest")
with respect to some or all of the shares allotted to that period, and may be
exercised with respect to some or all of the shares allotted to such period
and/or any prior period as to which the Option became vested but was not fully
exercised. The Option may be subject to such other terms and conditions on the
time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The vesting provisions of
individual Options may vary but in each case will provide for vesting of at
least twenty percent (20%) per year of the total number of shares subject to the
Option; provided, however, that an Option granted to an officer, director or
consultant (within the meaning of Section 260.140.41 of Title 10 of the
California Code of Regulations) may become fully exercisable, subject to
reasonable conditions such as continued employment, at any time or during any
period established by the Company or of any of its Affiliates. The provisions of
this subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.

         (f) SECURITIES LAW COMPLIANCE. The Company may require any Optionee, or
any person to whom an Option is transferred under subsection 6(d), as a
condition of exercising any such Option, (1) to give written assurances
satisfactory to the Company as to the Optionee's knowledge and experience in
financial and business matters and/or to employ a purchaser


                                       10

<PAGE>   11

representative reasonably satisfactory to the Company who is knowledgeable and
experienced in financial and business matters, and that he or she is capable of
evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the Option; and (2) to give written assurances satisfactory
to the Company stating that such person is acquiring the stock subject to the'
Option for such person's own account and not, with any present intention of
selling or otherwise distributing the stock. The foregoing requirements, and any
assurances given pursuant to such requirements, shall be inoperative if (i) the
issuance of the shares upon the exercise of the Option has been registered under
a then currently effective registration statement under the Securities Act, or
(ii) as to any particular requirement, a determination is made by counsel for
the Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may require the Optionee to provide
such other representations, written assurances or information which the Company
shall determine is necessary, desirable or appropriate to comply with applicable
securities and other laws as a condition of granting an Option to such Optionee
or permitting the Optionee to exercise such Option. The Company may, upon advice
of counsel to the Company, place legends on stock certificates issued under the
Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting
the transfer of the stock.

         (g) TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
disability), the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it as of the date of termination) but only
within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant, or such


                                       11

<PAGE>   12

longer or shorter period (which shall not be less than thirty (30) days, unless
such termination is for cause) specified in the Option Agreement, or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If,
at the date of termination, the Optionee is not entitled to exercise his or her
entire Option, the shares covered by the unexercisable portion of the Option
shall revert to and again become available for issuance under the Plan. If,
after termination, the Optionee does not exercise his or her Option within the
time specified in the Option Agreement, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

         (h) DISABILITY OF OPTIONEE. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it as of the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period, which in no event shall be less than six (6) months, specified
in the Option Agreement), or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, at the date of termination, the Optionee
is not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

         (i) DEATH OF OPTIONEE. In the event of the death of an Optionee during,
or within a period specified in the Option Agreement after the termination of,
the Optionee's Continuous Status as an Employee, Director or Consultant, the
Option may be exercised (to the extent the


                                       12

<PAGE>   13

Optionee was entitled to exercise the Option as of the date of death) by the
Optionee's estate, by a person who acquired the right to exercise the Option by
bequest or inheritance or by a person designated to exercise the option upon the
Optionee's death pursuant to subsection 6(d), but only within the period ending
on the earlier of (i) the date eighteen (18) months following the date of death
(or such longer or shorter period, which in no event shall be less than six (6)
months, specified in the Option Agreement), or (ii) the expiration of the term
of such Option as set forth in the Option Agreement. If, at the time of death,
the Optionee was not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again
become available for issuance under the Plan. If, after death, the Option is not
exercised within the time specified herein, the Option shall terminate, and the
shares covered by such Option shall revert to and again become available for
issuance under the Plan.

         (j) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased shall be subject to a repurchase right in favor of the Company, with
the repurchase price to be equal to the original purchase price of the stock, or
to any other restriction the Board determines to be appropriate; provided,
however, that (i) the right to repurchase at the original purchase price shall
lapse at a minimum rate of twenty percent (20%) per year over five (5) years
from the date the Option was granted, and (ii) such right shall be exercisable
only within (A) the ninety (90) day period following the termination of
Continuous Status as an Employee. Director or Consultant, or (B) such longer
period as may be agreed to by the Company and the Optionee (for example, for
purposes of satisfying the requirements of Section 1202(c)(3) of the Code
(regarding "qualified small business stock")), and (iii) such right


                                       13


<PAGE>   14

shall be exercisable only for cash or cancellation of purchase money
indebtedness for the shares. Notwithstanding the foregoing, shares received on
exercise of an Option by an officer, director or consultant (within the meaning
of Section 260.140.41 of Title 10 of the California Code of Regulations) may be
subject to additional or greater restrictions.

         (k) RIGHT OF REPURCHASE. The Option may, but need not, include a
provision whereby , the Company may elect, prior to the Listing Date, to
repurchase all or any part of the vested shares exercised pursuant to the
Option; provided, however, that (i) such repurchase right shall be exercisable
only within (A) the ninety (90) day period following the termination of
Continuous Status as an Employee, Director or Consultant (in the case of a
post-termination exercise of the Option then the ninety (90) day period
following the post-termination exercise), or (B) such longer period as may be
agreed to by the Company and the Optionee (for example, for purposes of
satisfying the requirements of Section 1202(c)(3) of the Code (regarding
qualified small business stock")), (ii) such repurchase right shall be
exercisable for less than all of the vested shares only with the Optionee's
consent, and (iii) such right shall be exercisable only for cash or cancellation
of purchase money indebtedness for the shares at a repurchase price equal to the
stock's Fair Market Value at the time of such termination. Notwithstanding the
foregoing, shares received on exercise of an Option by an officer, director or
consultant (within the meaning of Section 260.140.41 of Title 10 of the
California Code of Regulations) may be subject to additional or greater
restrictions specified in the Option Agreement.

         (l) RIGHT OF FIRST REFUSAL. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionee of the
intent to transfer all or any part of the shares


                                       14

exercised pursuant to the Option. Such right of first refusal shall comply with
the provisions of the Bylaws of the Company.

obligation relating to the exercise of such Option by any of the following means
or by a combination of such means: (1) tendering a cash payment; (2) authorizing
the Company to withhold shares from the shares of the common stock otherwise
issuable to the Optionee as a result of the exercise of the Option; or (3)
delivering to the Company owned and unencumbered shares of the common stock of
the Company.

7.       COVENANTS OF THE COMPANY.

         (a) During the terms of the Options, the Company shall keep available
at all times the number of shares of stock required to satisfy such Options.

         (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Options; provided, however,
that this undertaking shall not require the Company to register under the
Securities Act either the Plan, any Option or any stock issued or issuable
pursuant to any such Option. If, after reasonable efforts, the Company is unable
to obtain from any such regulatory commission or agency the authority which
counsel for the Company deems necessary for the lawful issuance and sale of
stock under the Plan, the Company shall be relieved from any liability for
failure to issue and sell stock upon exercise of such Options unless and until
such authority is obtained.

8.       USE OF PROCEEDS FROM STOCK.

Securities Law of 1968 and related regulations relied upon as a condition of
issuing securities pursuant to the Plan, the Board shall have the power to
accelerate the time at which an Option may first be exercised or the time during
which an Option or any part thereof will vest pursuant to subsection 6(e),
notwithstanding the provisions in the Option stating the time at which it may
first be exercised or the time during which it will vest.

         (b) Neither an Optionee nor any person to whom an Option is transferred
under subsection 6(d) shall be deemed to be the holder of, or to have any of the
rights of a holder with respect to, any shares subject to such Option unless and
until such person has satisfied all requirements for exercise of the Option
pursuant to its terms.

         (c) Throughout the term of any Option, the Company shall deliver to the
holder of such Option, not later than one hundred twenty (120) days after the
close of each of the Company's fiscal years during the Option term, a balance

Listing Date, or (ii) when issuance is limited to key employees whose duties in
connection with the Company assure them access to equivalent information.

         (d) Nothing in the Plan or any instrument executed or Option granted
pursuant thereto shall confer upon any Employee, Director, Consultant or
Optionee any right to continue in the employ of the Company or any Affiliate (or
to continue acting as a Director or Consultant) or shall affect the right of the
Company or any Affiliate to terminate the employment of any


                                       16

<PAGE>   17

Employee, with or without cause, to remove any Director as provided in the
Company's Bylaws and the provisions of the General Corporation Law of the state

terms of that Consultant's agreement with the Company or Affiliate to which such
Consultant is providing services.

         (e) To the extent that the aggregate Fair Market Value (determined at
the time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

         (f) (1) The Board shall have the authority to effect, at any time and
from time to time (i) the repricing of any outstanding Options under the Plan
and/or (ii) with the consent of the affected holders of Options, the
cancellation of any outstanding Options and the grant in substitution therefor
of new Options under the Plan covering the same or different numbers of shares
of common stock, but having an exercise price per share not less than
eighty-five percent (85%) of the Fair Market Value (one hundred percent (100%)
of the Fair Market Value in the case of an Incentive Stock Option or, in the
case of a ten percent (10%) shareholder (as defined in subsection 5(b)), not

of common stock on the new grant date.

               (2) Shares subject to an Option canceled under this subsection
9(f) shall continue to be counted, for the applicable period in which it was
granted, against the maximum award of Options permitted to be granted pursuant
to subsection 5(c) of the Plan. The repricing of an Option under this subsection
9(f), resulting in a reduction of the exercise price, shall be


                                       17

<PAGE>   18

deemed to be a cancellation of the original Option and the grant of a substitute
Option; in the event of such repricing, both the original and the substituted
Options shall be counted for the applicable period against the maximum awards of
Options permitted to be granted pursuant to subsection 5(c) of the Plan. The
provisions of this subsection 9(f)(2) shall be applicable only to the extent
required by Section 162(m) of the Code.

10.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (a) If any change is made in the stock subject to the Plan, or subject
to any Option (through merger, consolidation, reorganization, recapitalization,
stock dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or other transaction not involving the receipt of consideration by the
Company), the Plan will be appropriately adjusted in the type(s) and maximum
number of securities subject to the Plan pursuant to subsection 4(a) and the
maximum number of securities subject to award to any person during any calendar
year pursuant to subsection 5(c), and the outstanding Options will be
appropriately adjusted in the type(s) and number of securities and price per
share of stock subject to such outstanding Options. Such adjustments shall be
made by the Board, the determination "of which shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a "transaction not involving the receipt of consideration by
the Company.")

         (b) In the event of: (1) a dissolution, liquidation, or sale of all or
substantially all of the assets of the Company; (2) a merger or consolidation in
which the Company is not the surviving corporation; or (3) a reverse merger in
which the Company is the surviving corporation but the shares of the Company's
common stock outstanding immediately preceding the merger are converted by
virtue of the merger into other property, whether in the form of securities,
cash


                                       18

<PAGE>   19

or otherwise, then: (i) any surviving or acquiring corporation shall assume
Options outstanding under the Plan or shall substitute similar options
(including an option to acquire the same consideration paid to shareholders in
the transaction described in this Subsection 10(b)) for those outstanding under
the Plan, or (ii) in the event any surviving or acquiring corporation refuses to
assume such Options or to substitute similar options for those outstanding under
the Plan, (A) with respect to Options held by persons then performing services
as Employees, Directors or Consultants and subject to any applicable provisions
of the California Corporate Securities Law of 1968 and related regulations
relied upon as a condition of issuing securities pursuant to the Plan, the
vesting of such Options and the time during which such Options may be exercised
shall be accelerated prior to such event and the Options terminated if not
exercised after such acceleration and at or prior to such event, and (B) with
respect to any other Options outstanding under the Plan, such Options shall be
terminated if not exercised prior to such event.

11.      AMENDMENT OF THE PLAN AND OPTIONS.

         (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 10 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the shareholders of
the Company to the extent such modification requires shareholder approval in
order for the Plan to satisfy the requirements of Section 422 of the Code, Rule
16b-3, or applicable requirements for listing with Nasdaq or other stock
exchange.

         (b) The Board may in its sole discretion submit any other amendment to
the Plan for shareholder approval, including, but not limited to, amendments to
the Plan intended to satisfy the requirements of Section 162(m) of the Code and
the regulations promulgated thereunder

regarding the exclusion of performance-based compensation from the, limit on
corporate deductibility of compensation paid to certain executive officers.

any respect the Board deems necessary or advisable to provide Optionees with the
maximum benefits provided, or to be provided under the provisions of the Code
and the regulations promulgated thereunder relating to Incentive Stock Options
and/or to bring the Plan and/or Incentive Stock Options granted under it into
compliance therewith.

         (d) Rights and obligations under any Option granted before amendment of
the Plan shall not be impaired by any amendment of the Plan unless (i) the
Company requests the consent of the person to whom the Option was granted and
(ii) such person consents in writing.

         (e) The Board at any time, and from time to time, may amend the terms
of any one or more Options; provided, however, that the rights and obligations
under any Option shall not be impaired by any such amendment unless (i) the
Company requests the consent of the person to whom the Option was granted and
(ii) such person consents in writing.

12.      TERMINATION OR SUSPENSION OF THE PLAN.

         (a) The Board may suspend or terminate the Plan at any time. Unless
sooner terminated, the Plan shall terminate on April 1, 2007, which shall be
within ten (10) years from the date the Plan is adopted by the Board or approved
by the shareholders of the Company, whichever is earlier. No Options may be
granted under the Plan while the Plan is suspended or after it is terminated.

         (b) Rights and obligations under any Option granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan, except
with the written consent of the person to whom the Option was granted.

13.      EFFECTIVE DATE OF PLAN.

                               ISTARI DESIGN, INC.

                             1997 STOCK OPTION PLAN

                             INCENTIVE STOCK OPTION


___________________, Optionee:

         Istari Design, Inc. (the "Company"), pursuant to its 1997 Stock Option
Plan (the "Plan"), has granted to you, the optionee named above, an option to
purchase shares of the common stock of the Company ("Common Stock"). This option
is intended to qualify as an "incentive stock option" within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

         The grant hereunder is in connection with and in furtherance of the
Company's compensatory benefit plan for participation of the Company's employees
(including officers), directors or consultants and is intended to comply with
the provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the Securities Act of 1933, as amended.(the "Act"). The grant of this
option and the issuance of shares upon the exercise of this option are also
intended to be exempt from the securities qualification requirements of the
California Corporations Code pursuant to Section 25102(o) of that code. Defined
terms not explicitly defined in this agreement but defined in the Plan shall
have the same definitions as in the Plan.

         The details of this option are as follows:

         1. TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION. The total number of
shares of Common Stock subject to this option is____________________
(__________).

         2. VESTING. Subject to the limitations contained herein, of the shares
will vest (become exercisable) on _____________, 19__ and __________ of the
shares will then vest each thereafter until either (i) you cease to provide
services to the Company for any reason, or (ii).this option becomes fully
vested. [N.B. Other vesting schedules are permissible as long as vesting for
non-officer employees is 20% per year]

         3. EXERCISE PRICE AND METHOD OF PAYMENT.

               (a). EXERCISE PRICE. The exercise price of this option is ___ per
share, being not less than the fair market value of the Common Stock on the date
of grant of this option.

               (b). METHOD OF PAYMENT. Payment of the exercise price per share
is due in full upon exercise of all or any part of each installment which has
accrued to you. You may elect, to the extent permitted by applicable statutes
and regulations, to make payment of the exercise price under one of the
following alternatives:

                    (i) Payment of the exercise price per share in cash
(including check) at the time of exercise;


                                       1
<PAGE>   2

                    (ii) Payment pursuant to a program developed under,
Regulation T as promulgated by the Federal Reserve Board which, prior to the
issuance of Common Stock, results in either the receipt of cash (or check) by
the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds;

                    (iii) Provided that at the time of exercise the Company's
Common Stock is publicly traded and quoted regularly in the Wall Street Journal,
payment by delivery of already-owned shares of Common Stock, held for the period
required to avoid a charge to the Company's reported earnings, and owned free
and clear of any liens, claims, encumbrances or security interests, which Common
Stock shall be valued at its fair market value on the date of exercise; or

                    (iv) Payment by a combination of the methods of payment
permitted by subparagraph 3(b)(i) through 3(b)(iii) above.

         4. WHOLE SHARES. This option may not be exercised for any number of
shares which would require the issuance of anything other than whole shares.

         5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Act or, if such
shares are not then so registered, the Company has determined that such exercise
and issuance would be exempt from the registration requirements of the Act.

         6. TERM. The term of this option commences on _________________, the
date of grant, and expires on __________________ (the "Expiration Date"), unless
this option expires sooner as set forth below or in the Plan. In no event may
this option be exercised on or after the Expiration Date. This option shall
terminate prior to the Expiration Date as follows: three (3) months after the
termination of your Continuous Status as an Employee, Director or Consultant
with the Company or an Affiliate unless one of the following circumstances
exists:

               (a). Your termination of Continuous Status as an Employee,
Director or Consultant is due to your disability. This option will then expire
on the earlier of the Expiration Date set forth above or twelve (12) months
following such termination of Continuous Status as an Employee, Director or
Consultant. You should be aware that if your disability is not considered a
permanent and total disability within the meaning of Section 422(c)(6) of the
Code, and you exercise this option more than three (3) months following the date
of your termination of employment, your exercise will be treated for tax
purposes as the exercise of a "nonstatutory stock option" instead of an
"incentive stock option."

               (b). Your termination of Continuous Status as an Employee,
Director or Consultant is due to your death or your death occurs within three
(3) months following your termination of Continuous Status as an Employee,
Director or Consultant for any other reason. This option will then expire on the
earlier of the-Expiration Date set forth above or twelve (12) months after your
death.


                                       2
<PAGE>   3

               (c). If during any part of such three (3) month period you may
not exercise this option solely because of the condition set forth in paragraph
5 above, then this option will not expire until the earlier of the Expiration
Date set forth above or until this option shall have been exercisable for an
aggregate period of three (3) months after your termination of Continuous Status
as an Employee, Director or Consultant.

               (d). If your exercise of this option within three (3) months
after termination of your Continuous Status as an Employee, Director or
Consultant with the Company or with an Affiliate would result in liability under
section 16(b) of the Securities Exchange Act of 1934, then this option will
expire on the earlier of (i) the Expiration Date set forth above, (ii) the tenth
(10th) day after the last date upon which exercise would result in such
liability or (iii) six (6) months and ten (10) days after the termination of
your Continuous Status as an Employee, Director or Consultant with the Company
or an Affiliate.

         However, this option may be exercised following termination of
Continuous Status as an Employee, Director or Consultant only as to that number
of shares as to which it was exercisable on the date of termination of
Continuous Status as an Employee, Director or Consultant under the provisions of
paragraph 2 of this option.

         In order to obtain the federal income tax advantages associated with an
"incentive stock option," the Code requires that at all times beginning on the
date of grant of the option and ending on the day three (3) months before the
date of the option's exercise, you must be an employee of the Company or an
Affiliate, except in the event of your death or permanent and total disability.
The Company has provided for continued vesting or extended exercisability of
this option under certain circumstances for your benefit, but cannot guarantee
that this option will necessarily be treated as an "incentive stock option" if
you provide services to the Company or an Affiliate as a consultant or exercise
this option more than three (3) months after the date your employment with the
Company and all Affiliates terminates.

         7. EXERCISE.

               (a). This option may be exercised, to the extent specified above,
by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require pursuant
to subsection 6(f) of the Plan.

               (b). By exercising this option you agree that:

                    (i) as a precondition to the completion of any exercise of
this option, the Company may require you to enter an arrangement providing for
the payment by you to the Company of any tax withholding obligation of the
Company arising by reason of (1) the exercise of this option; (2) the lapse of
any substantial risk of forfeiture to which the shares are subject at the time
of exercise; or (3) the disposition of shares acquired upon such exercise;

                    (ii) you will notify the Company in writing within fifteen
(15) days after the date of any disposition of any of the shares of the Common
Stock issued upon exercise of this option that occurs within two (2) years after
the date of this option grant or


                                       3
<PAGE>   4

within one (1) year after such shares of Common Stock are transferred upon
exercise of this option; and

                    (iii) the Company (or a representative of the underwriters)
may, in connection with the first underwritten registration of the offering of
any securities of the Company under the Act, require that you not sell, dispose
of, transfer, make any short sale of, grant any option for the purchase of, or
enter into any hedging or similar transaction with the same economic effect as a
sale, any shares of Common Stock or other securities of the Company held by you,
for a period of time specified by the underwriter(s) (not to exceed one hundred
eighty (180) days) following the effective date of a registration statement of
the Company filed under the Act. You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company and/or the
underwriter(s) which are consistent with the foregoing or which are necessary to
give further effect thereto. In order to enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to your Common Stock
until the end of such period.

         8. TRANSFERABILITY. This option is not transferable, except by will or
by the laws of descent and distribution, and is exercisable during your life
only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise this
option.

         9. OPTION NOT A SERVICE CONTRACT. This option is not an employment
contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company,
or of the Company to continue your employment with the Company. In addition,
nothing in this option shall obligate the Company or any Affiliate, or their
respective shareholders, Board of Directors, officers or employees to continue
any relationship which you might have as a Director or Consultant for the
Company or an Affiliate.

         10. NOTICES. Any notices provided for in this option or the Plan shall
be given in writing and shall be deemed effectively given upon receipt or, in
the case of notices delivered by the Company to you, five (5) days after deposit
in the United States mail, postage prepaid addressed to you at the address
specified below or at such other address as you hereafter designate by written
notice to the Company.

         11. GOVERNING PLAN DOCUMENT. This option is subject to all the
provisions of the Plan, a copy of which is attached hereto and its provisions
are hereby made a part of this option, including without limitation the
provisions of Section 6 of the Plan relating to option provisions, and is
further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. In the
event of any conflict between the provisions of this option and those of the
Plan, the provisions of the Plan shall control.

            (d) If your exercise of this option within three (3) months after

                             CONEXANT SYSTEMS, INC.

                        STOCK OPTION ASSUMPTION AGREEMENT
                               ISTARI DESIGN, INC.

                                 1997 STOCK PLAN

OPTIONEE: [Optionee Name]

         STOCK OPTION ASSUMPTION AGREEMENT effective as of the 9th day of
November, 1999 by Conexant Systems, Inc., a Delaware corporation ("Conexant").

         WHEREAS, the undersigned individual ("Optionee") holds one or more
outstanding options to purchase shares of the common stock of Istari Design,
Inc., a California corporation ("Istari"), which were granted to Optionee under
the Istari Design, Inc. 1997 Stock Option Plan (the "Plan") and are each
evidenced by a Stock Option Agreement (the "Option Agreement");

         WHEREAS, Istari has been acquired by Conexant through the merger of
Istari Acquisition Corp., a Delaware corporation and a wholly owned subsidiary
of Conexant, with and into Conexant (the "Merger") pursuant to the Agreement and
Plan of Reorganization, dated November 9, 1999, by and among Conexant, Istari
Acquisition Corp. and Istari (the "Merger Agreement");

         WHEREAS, the provisions of the Merger Agreement require Conexant to
assume all obligations of Istari under all outstanding options under the Plan at
the consummation of the Merger (except for options held by a certain individual,
which will be cancelled as of the Effective Time, as hereinafter defined), and
this Agreement evidences the assumption of such options by Conexant;

         WHEREAS, pursuant to the provisions of the Merger Agreement, the
exchange ratio (the "Exchange Ratio") in effect for the Merger is 0.035895
shares of Conexant common stock ("Conexant Stock") for each outstanding share of
Istari common stock ("Istari Stock"); and

         WHEREAS, this Agreement became effective immediately upon the
consummation of the Merger (the "Effective Time") in order to reflect certain
adjustments to Optionee's outstanding options that have become necessary by
reason of the assumption of those options by Conexant in connection with the
Merger.

         NOW, THEREFORE, it is hereby agreed as follows:

         1. The number of shares of Istari Stock subject to the options held by
Optionee immediately prior to the Effective Time (the "Istari Options") and the
exercise price payable per share are set forth below. Conexant hereby assumes,
as of the Effective Time, all the duties and obligations of Istari under each of
the Istari Options. In connection with such assumption, the number of shares of
Conexant Stock purchasable under each Istari Option hereby assumed and the
exercise price payable thereunder have been adjusted to reflect the Exchange
Ratio. Accordingly, the number of shares of Conexant Stock subject to each
Istari Option hereby


                                       1
<PAGE>   2
assumed shall be as specified for that option below, and the adjusted exercise
price payable per share of Conexant Stock under the assumed Istari Option shall
also be as indicated for that option below.

                                 ISTARI OPTIONS

          PRE-MERGER                         AS ASSUMED BY CONEXANT
- ---------------------------------   --------------------------------------
 # of Shares of    Exercise Price      # of Shares       Adjusted Exercise
  Istari Stock       per Share      of Conexant Stock     Price per Share
 --------------    --------------   -----------------    -----------------


         2. The intent of the foregoing adjustments to each assumed Istari
Option is to assure that the spread between the aggregate fair market value of
the shares of Conexant Stock purchasable under each such option and the
aggregate exercise price as adjusted pursuant to this Agreement will,
immediately after the consummation of the Merger, be not less than the spread
which existed, immediately prior to the Merger, between the then aggregate fair
market value of the Istari Stock subject to the Istari Option and the aggregate
exercise price in effect at such time under the Option Agreement. Such
adjustments are also intended to preserve, immediately after the Merger, on a
per share basis, the same ratio of exercise price per option share to fair
market value per share which existed under the Istari Option immediately prior
to the Merger.

         3. The following provisions shall govern each Istari Option hereby
assumed by Conexant:

                  a.       Unless the context otherwise requires, all references
                           in each Option Agreement and in the Plan (i) to the
                           "Company" shall mean Conexant, (ii) to "Shares,"
                           "Stock" or "Common Stock" shall mean shares of
                           Conexant Stock, (iii) to the "Board of Directors"
                           shall mean the Board of Directors of Conexant and
                           (iv) to the "Committee" shall mean the Compensation
                           Committee of the Conexant Board of Directors.

                  b.       The grant date and the expiration date of each
                           assumed Istari Option and all other provisions that
                           govern either the exercise or the termination of the
                           assumed Istari Option shall remain the same as set
                           forth in the Plan and the Option Agreement applicable
                           to that option, and the provisions of the Plan and
                           the Option Agreement shall accordingly govern and
                           control Optionee's rights to purchase Conexant Stock
                           under the assumed Istari Option.

                  c.       Pursuant to the terms of the Option Agreement, none
                           of your Istari Options as assumed by Conexant in
                           connection with the transaction vested or became
                           exercisable on an accelerated basis upon the
                           consummation of the Merger. Accordingly, each such
                           assumed Istari Option shall continue to vest for any
                           remaining unvested shares of Conexant Stock subject
                           to that option in


                                       2
<PAGE>   3

                           accordance with the same installment vesting schedule
                           in effect under the applicable Option Agreement
                           immediately prior to the Effective Time; provided,
                           however, that the number of shares subject to each
                           such installment shall be adjusted to reflect the
                           Exchange Ratio.

                  d.       For purposes of applying any and all provisions of
                           the Option Agreement relating to Optionee's status as
                           an employee, director, consultant, or advisor
                           providing service to Istari, Optionee, shall be
                           deemed to continue in such status for so long as
                           Optionee renders service as an employee, director,
                           consultant, or advisor, respectively, to Conexant or
                           a subsidiary. Accordingly, the provisions of the
                           Option Agreement governing the termination of the
                           assumed Istari Options upon Optionee's cessation of
                           service with Istari shall hereafter be applied on the
                           basis of Optionee's cessation of such service with
                           respect to Conexant or a subsidiary, and each assumed
                           Istari Option shall accordingly terminate, within the
                           designated time period in effect under the Option
                           Agreement for that option, following such cessation
                           of such service for Conexant or a subsidiary.

                  e.       The adjusted exercise price payable for the Conexant
                           Stock subject to each assumed Istari Option shall be
                           payable in any of the forms authorized under the
                           Option Agreement applicable to that option. For
                           purposes of determining the holding period of any
                           shares of Conexant Stock delivered in payment of such
                           adjusted exercise price, the period for which such
                           shares were held as Istari Stock prior to the Merger
                           shall be taken into account.

                  f.       In order to exercise each assumed Istari Option,
                           Optionee must deliver to Conexant a written notice of
                           exercise in which the number of shares of Conexant
                           Stock to be purchased thereunder must be indicated.
                           The exercise notice must be accompanied by payment of
                           the adjusted exercise price payable for the purchased
                           shares of Conexant Stock and should be delivered to
                           Conexant at the following address:
