           -------

          (a) Each stockholder shall, at each meeting of the stockholders, be
entitled to vote in person or by proxy each share or fractional share of the
stock of the Corporation having voting rights on the matter in question and
which shall have been held by him and registered in his name on the books of the
Corporation:

               (i) on the date fixed pursuant to Section 6.05 of these Bylaws as
     the record date for the determination of stockholders entitled to notice of
     and to vote at such meeting, or

               (ii) if no such record date shall have been so fixed, then at the
     close of business on the day next preceding the day on which notice of the
     meeting shall be given or, if notice of the meeting shall be waived, at the
     close of business on the day next preceding the day on which the meeting
     shall be held.

          (b) Shares of its own stock belonging to the Corporation or to another
corporation, if a majority of the shares entitled to vote in the election of
directors in such other corporation is held, directly or indirectly, by the
Corporation, shall neither be entitled to vote nor be counted for quorum
purposes.  Persons holding stock of the Corporation in a fiduciary capacity
shall be entitled to vote such stock.  Persons whose stock is pledged shall be
entitled to vote, unless in the transfer by the pledgor on the books of the
Corporation he shall have expressly empowered the pledgee to vote thereon, in
which case only the pledgee, or his proxy, may represent such stock and vote
thereon.  Stock having voting power standing of

                                       2
<PAGE>

record in the names of two or more persons, whether fiduciaries, members of a
partnership, joint tenants in common, tenants by entirety or otherwise, or with
respect to which two or more persons have the same fiduciary relationship, shall
be voted in accordance with the provisions of the General Corporation Law of the
State of Delaware.

          (c) Any such voting rights may be exercised by the stockholder
entitled thereto in person or by his proxy appointed by an instrument in
writing, subscribed by such stockholder or by his attorney thereunto authorized
and delivered to the secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall provide for a longer period.  The attendance at any meeting of a
stockholder who may theretofore have given a proxy shall not have the effect of
revoking the same unless he shall in writing so notify the secretary of the
meeting prior to the voting of the proxy.  At any meeting of the stockholders
all matters, except as otherwise provided in the Certificate of Incorporation,
in these Bylaws or by law, shall be decided by the vote of a majority in voting
interest of the stockholders present in person or by proxy and entitled to vote
thereat and thereon, a quorum being present.  The vote at any meeting of the
stockholders on any question need not be by ballot, unless so directed by the
chairman of the meeting.  On a vote by ballot each ballot shall be signed by the
stockholder voting, or by his proxy, if there be such proxy, and it shall state
the number of shares voted.

     2.07  List of Stockholders.  The Secretary of the Corporation shall prepare
           --------------------
and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

     2.08  Judges.  If at any meeting of the stockholders a vote by written
           -------
ballot shall be taken on any question, the chairman of such meeting may appoint
a judge or judges to act with respect to such vote.  Each judge so appointed
shall first subscribe an oath faithfully to execute the duties of a judge at
such meeting with strict impartiality and according to the best of his ability.
Such judges shall decide upon the qualification of the voters and shall report
the number of shares represented at the meeting and entitled to vote on such
question, shall conduct and accept the votes, and, when the voting is completed,
shall ascertain and report the number of shares voted respectively for and
against the question.  Reports of judges shall be in writing and subscribed and
delivered by them to the Secretary of the Corporation.  The judges need not be
stockholders of the Corporation, and any officer of the Corporation may be a
judge on any question other than a vote for or against a proposal in which he
shall have a material interest.

     2.09  Action Without Meeting.  Any action required to be taken at any
           ----------------------
annual or special meeting of stockholders of the Corporation, or any action that
may be taken at any annual or special meeting of such stockholders, may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted.  Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.
Notwithstanding the foregoing, after the closing of the Corporation's first
underwritten public offering ("Initial Public Offering") pursuant to which the
Corporation shall have a class of stock registered pursuant to the provisions of
the Securities Exchange Act of 1934, as amended (the "1934 Act"), and for so
long as such class is so registered, any action by the stockholders of such
class must be taken at an annual or special meeting of stockholders and may not
be taken by written consent.

     2.10  Advance Notice of Stockholder Business.  At any meeting of the
           ---------------------------------------
stockholders, only such business shall be conducted as shall have been brought
before the meeting (i) by or at the direction of the Board or (ii) by any
stockholder of the Corporation who complies with the notice procedures set forth
in this Section 2.10 and Section 2.11 of Article II.  For business to be
properly brought before any meeting of the stockholders by a stockholder, the
stockholder must have given notice thereof in writing to the Secretary of the
Corporation not less than 90 days in advance of such meeting or, if later, the
tenth day following the first public announcement of the date of such meeting,
and such business must be a proper matter for stockholder action under the
General Corporation Law of the State of Delaware.  A stockholder's notice to the
Secretary shall set forth as to each matter the stockholder proposes to bring
before the meeting (1) a brief description of the business desired to be brought
before the meeting and the reasons for conducting such business at the meeting,
(2) the name and address, as they appear on the Corporation's books, of the
stockholder proposing such business, (3) the class and number of shares of the
Corporation that are beneficially owned by the stockholder, and (4) any material
interest of the stockholder in such business.  In addition, the stockholder
making such proposal shall promptly provide any other information reasonably
requested by the Corporation.  The chairman of any such meeting shall have the
power and the duty to determine whether any business proposed to be brought
before the meeting has been made in accordance with the procedure set forth in
these Bylaws and shall direct that any business not properly brought before the
meeting shall not be considered.  Notwithstanding anything in these Bylaws to
the contrary, no business shall be conducted at any meeting of the stockholders
except in accordance with the procedures set forth in this Section 2.10 and
Section 2.11 of Article II.  For purposes of this Section 2.10 and Section 2.11
of Article II, "public announcement" shall mean disclosure in a press release
reported by the Dow Jones News Service, Associated Press or a comparable
national news service or in a document publicly filed by the Corporation with
the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of
the Securities Exchange Act of 1934, as amended, or any successor provision.

     2.11  Advance Notice of Stockholder Nominees.  Nominations for the election
           --------------------------------------
of directors may be made by the Board or by any stockholder entitled to vote in
the election of

                                       4
<PAGE>

directors; provided, however, that a stockholder may nominate a person for
election as a director at a meeting only if written notice of such stockholder's
intent to make such nomination has been given to the Secretary of the
Corporation not later than 90 days in advance of such meeting or, if later, the
tenth day following the first public announcement of the date of such meeting.
Each such notice shall set forth: (i) the name and address of the stockholder
who intends to make the nomination and of the person or persons to be nominated;
(ii) a representation that the stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting and nominate the person or persons specified in the
notice; (iii) a description of all arrangements or understandings between the
stockholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nomination or nominations are to be made by
the stockholder, (iv) such other information regarding each nominee proposed by
such stockholder as would be required to be included in a proxy statement filed
pursuant to the proxy rules of the Securities and Exchange Commission had the
nominee been nominated, or intended to be nominated, by the Board; and (v) the
consent of each nominee to serve as a director of the Corporation if so elected.
In addition, the stockholder making such nomination shall promptly provide any
other information reasonably requested by the Corporation. Notwithstanding the
foregoing provisions of this Section 2.11 of Article II, in the event that the
number of directors to be elected to the Board is increased and there is no
public announcement naming either all of the nominees for director or specifying
the size of the increased Board made by the Corporation at least 100 days in
advance of such meeting, a stockholder's notice required by this Section 2.11 of
Article II shall be considered timely, but only with respect to nominees for any
new positions created by such increase, if it shall be delivered to the
Secretary of the Corporation not later than the tenth day following the day on
which such public announcement is first made by the Corporation. No person shall
be eligible for election as a director of the Corporation unless nominated in
accordance with the procedures set forth in this Section 2.11 of Article II. The
chairman of any meeting of stockholders shall have the power and the duty to
determine whether a nomination has been made in accordance with the procedure
set forth in this Section 2.11 of Article II and shall direct that any
nomination not made in accordance with these procedures be disregarded.

than a quorum.  Each director so chosen to fill a vacancy shall hold office
until his successor shall have been elected and shall qualify or until he shall

     3.13  Compensation.  The directors shall receive only such compensation for
           ------------
their services as directors as may be allowed by resolution of the Board.  The
Board may also provide that the Corporation shall reimburse each such director

            -----------------------
otherwise provided, may authorize any officer or officers, agent or agents, to

                           SHARES AND THEIR TRANSFER

     6.01   Certificates for Stock.  Every owner of stock of the Corporation
            -----------------------
shall be entitled to have a certificate or certificates, to be in such form as
the Board shall prescribe, certifying the number and class of shares of the
stock of the Corporation owned by him.  The certificates representing shares of
such stock shall be numbered in the order in which they shall be issued and
shall be signed in the name of the Corporation by the Chairman of the Board, the
President or a Vice President, and by the Secretary or an Assistant Secretary or
by the Chief Financial Officer or the Treasurer or an Assistant Treasurer.  Any
of or all of the signatures on the certificates may be a facsimile.  In case any
officer, transfer agent or registrar who has signed, or whose facsimile
signature has been placed upon, any such certificate, shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued,
such certificate may nevertheless be issued by the Corporation with the same
effect as though the person who signed such certificate, or whose facsimile
signature shall have been placed thereupon, were such officer, transfer agent or
registrar at the date of issue.  A record shall be kept of the respective names
of the persons, firms or corporations owning the stock represented by such
certificates, the number and class of shares represented by such certificates,
respectively, and the respective dates thereof, and in case of cancellation, the
respective dates of cancellation.  Every certificate surrendered to the
Corporation for exchange or transfer shall be cancelled, and no new certificate
or certificates shall be issued in exchange for any existing certificate until
such existing certificate shall have been so cancelled, except in cases provided
for in Section 6.04.

     6.02   Transfers of Stock.  Transfers of shares of stock of the Corporation
            -------------------
shall be made only on the books of the Corporation by the registered holder

executed and filed with the Secretary, or with a transfer clerk or a transfer
agent appointed as provided in Section 6.03, and upon surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes thereon.  The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation.  Whenever any transfer of shares shall be made for collateral
security, and not absolutely, such fact shall be so expressed in the entry of
transfer if, when the certificate or certificates shall be presented to

                                      11
<PAGE>

the Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

     6.03   Regulations.  The Board may make such rules and regulations as it
            ------------
may deem expedient, not inconsistent with these Bylaws, concerning the issue,
transfer and registration of certificates for shares of the stock of the
Corporation.  It may appoint, or authorize any officer or officers to appoint,
one or more transfer clerks or one or more transfer agents and one or more
registrars, and may require all certificates for stock to bear the signature or
signatures of any of them.

     6.04   Lost, Stolen, Destroyed, and Mutilated Certificates.  In any case of
            ----------------------------------------------------
loss, theft, destruction, or mutilation of any certificate of stock, another may
be issued in its place upon proof of such loss, theft, destruction, or
mutilation and upon the giving of a bond of indemnity to the Corporation in such
form and in such sum as the Board may direct; provided, however, that a new
certificate may be issued without requiring any bond when, in the judgment of
the Board, it is proper so to do.

     6.05   Fixing Date for Determination of Stockholders of Record.  In order
            --------------------------------------------------------
that the Corporation may determine the stockholders entitled to notice of or to
vote at any meeting of stockholders or any adjournment thereof, or to express
consent to corporate action in writing without a meeting, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or
entitled to exercise any rights in respect of any other change, conversion or
exchange of stock or for the purpose of any other lawful action, the Board may
fix, in advance, a record date, which shall not be more than 60 nor less than 10
days before the date of such meeting, nor more than 60 days prior to any other
action.  If in any case involving the determination of stockholders for any
purpose other than notice of or voting at a meeting of stockholders or
expressing consent to corporate action without a meeting the Board shall not fix
such a record date, the record date for determining stockholders for such
purpose shall be the close of business on the day on which the Board shall adopt
the resolution relating thereto.  A determination of stockholders entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of such meeting; provided, however, that the Board may fix a new record date for
the adjourned meeting.

     6.06   Restrictions on Transfer.
            -------------------------

          (a) Notwithstanding Section 6.02,  (i) all of the shares of
Corporation's common stock, par value $0.001 (the "Common Stock"), outstanding

pursuant to options and warrants of the Corporation outstanding immediately
prior to the Effective Date, may not be offered, sold, pledged or otherwise
disposed of, directly or indirectly, nor may the holders of such shares publicly
disclose the intention to make any such offer, sale pledge or disposal, for up
to 180 days after the Effective Date without the prior written consent of Virata
Corporation, except to a transferee permitted (a "Permitted Transferee") under
Sub-section (b) of this Section 6.06, provided that any such Permitted
Transferee shall agree in writing to be bound by the provisions of this Section
6.06.

                                      12
<PAGE>

          (b) For purposes of this Section 6.06, a Permitted Transferee shall
mean: (i) the spouse or child of a transferor; (ii) a trust for the sole benefit
of a transferor or a transferor's spouse or child, if the transferor is an
individual; (iii) the estate of a deceased transferor; (iv) a partner, general
partner, limited partner or retired partner of a transferor that is a

          (c) A legend denoting the transfer restrictions set forth in this
Section 6.06 substantially similar to the following form will be stamped or
otherwise imprinted on the certificates representing such shares:

     "THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE MAY NOT BE
     TRANSFERRED, OFFERED, SOLD, PLEDGED OR OTHERWISE DISPOSED OF, DIRECTLY OR
     INDIRECTLY, NOR MAY THE HOLDERS OF THE SHARES PUBLICLY DISCLOSE THE
     INTENTION TO MAKE ANY SUCH OFFER, SALE PLEDGE OR DISPOSAL, FOR UP TO 180
     DAYS AFTER THE EFFECTIVE DATE OF THE CORPORATION'S REGISTRATION STATEMENT
     ON FORM 8-A, WHICH WAS FILED WITH THE U.S. SECURITIES AND EXCHANGE
     COMMISSION ON NOVEMBER 17, 1999, WITHOUT THE PRIOR WRITTEN CONSENT OF THE
     CORPORATION, EXCEPT TO A TRANSFEREE PERMITTED UNDER SECTION 6.06 OF THE
     CORPORATION'S BYLAWS.  NO TRANSFEREE WHO RECEIVES THE SHARES REPRESENTED BY
     THIS CERTIFICATE IN CONNECTION WITH A TRANSFER THAT DOES NOT MEET THE
     QUALIFICATIONS PRESCRIBED IN SECTION 6.06 OF THE CORPORATION'S BYLAWS IS
     ENTITLED TO OWN OR TO BE REGISTERED AS THE RECORD HOLDER OF THE SHARES OF
     COMMON STOCK REPRESENTED BY THIS CERTIFICATE."

          (d) In furtherance of the foregoing, the Corporation and its transfer
agent and registrar, if any, will not make any transfer of the Corporation's
Common Stock if such a transfer would constitute a violation or breach of this
Section 6.06.

                                  ARTICLE VII

                                INDEMNIFICATION

     7.01   Action, Etc. Other Than by or in the Right of the Corporation.  The
            --------------------------------------------------------------
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation) by reason of the fact that he
is or was a director, officer, employee or agent of the Corporation, or is or
was serving at the request of the Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he 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

                                      13
<PAGE>

no reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, that he had
reasonable cause to believe that his conduct was unlawful.

     7.02   Actions, Etc., by or in the Right of the Corporation.  The
            -----------------------------------------------------
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

     7.03   Determination of Right of Indemnification.  Unless otherwise ordered
            ------------------------------------------
by a court of competent jurisdiction, any indemnification under Sections 7.01 or
7.02 of this Article VII shall be made by the Corporation to any person who is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, unless a determination is reasonably and promptly made, either (i)
by the Board of Directors acting by a majority vote of a quorum consisting of
directors who were not a party to such action, suit or proceeding, or (ii) if
such a quorum is not obtainable, or, if obtainable, such quorum so directs, by
independent legal counsel in a written opinion, or (iii) by the stockholders,
that such person acted in bad faith and in a manner that such person did not
believe to be in or not opposed to the best interests of the Corporation or,
with respect to any criminal proceeding, that such person believed or had
reasonable cause to believe, that his or her conduct was unlawful.

     7.04   Indemnification Against Expenses of Successful Party.
            -----------------------------------------------------
Notwithstanding the other provisions of this Article, to the extent that a
director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

                                      14
<PAGE>

     7.05   Prepaid Expenses.  Expenses incurred by an officer or director in
            -----------------
defending a civil or criminal action, suit or proceeding may be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount
unless it shall ultimately be determined that he is entitled to be indemnified
by the Corporation as authorized in this Article.  Such expenses incurred by
other employees and agents may be so paid upon such terms and conditions, if
any, as the Board deems appropriate.

     7.06   Other Rights and Remedies.  The indemnification provided by this
            --------------------------
Article shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any Bylaws, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

     7.07   Insurance.  Upon resolution passed by the Board, the Corporation may
            ----------
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under the
provisions of this Article.

     7.08   Constituent Corporations.  For the purposes of this Article,
            -------------------------
references to "the Corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article with respect to the resulting or
surviving corporation as he would if he had served the resulting or surviving
corporation in the same capacity.

     7.09   Other Enterprises, Fines, and Serving at Corporation's Request.  For
            ---------------------------------------------------------------
purposes of this Article, references to "other enterprises" shall include
employee benefit plans; references to "fines" shall include any excise taxes
assessed on a person with respect to any employee benefit plan; and references
to "serving at the request of the Corporation" shall include any service as a
director, officer, employee or agent of the Corporation which imposes duties on,
or involves services by, such director, officer, employee, or agent with respect
to an employee benefit plan, its participants, or beneficiaries; and a person
who acted in good faith and in a manner he reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit plan shall
be deemed to have acted in a manner "not opposed to the best interests of the
Corporation" as referred to in this Article.

                                 MISCELLANEOUS

     8.01   Seal.  The Board may provide a corporate seal, which shall be in the
            -----
form of a circle and shall bear the name of the Corporation and words and
figures showing that the Corporation was incorporated in the State of Delaware
and the year of incorporation.

     8.02   Waiver of Notices.  Whenever notice is required to be given by these
            ------------------
Bylaws or the Certificate of Incorporation or by law, the person entitled to
