               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.    Incorporation of Documents by Reference.
           --------------------------------------

           The following documents and information are incorporated by reference
as filed with the Securities and Exchange Commission:

           (a)  PMC-Sierra,  Inc.'s  ("PMC's")  Form 10-K Annual  Report for the
                fiscal year ended December 26, 1999 (File No. 000-19084).

           (b)  PMC's Form 8-K dated March 20, 2000 (File No. 000-19084).

           (c)  The  description  of PMC's Common Stock to be offered  hereby is
                contained in the Company's Quarterly Report on Form 10-Q for the
                fiscal  quarter ended on June 27, 1999 filed with the Commission
                pursuant to Section  13(a) of the Exchange  Act,  including  any
                amendment  or report  filed for the  purpose  of  updating  such
                description.

           All documents  subsequently  filed by PMC pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended, prior to
the filing of a  post-effective  amendment  which  indicates that all securities
offered  have been  sold or which  deregisters  all  securities  then  remaining
unsold,  shall be deemed to be  incorporated  by reference in this  registration
statement and to be part hereof from the date of filing such documents.

Item 4.    Description of Securities.
           -------------------------
           Not applicable.

Item 5.    Interests of Named Experts and Counsel.
           --------------------------------------
           Certain  legal matters with respect to the shares will be passed upon
by Wilson, Sonsini,  Goodrich & Rosati, a Professional  Corporation,  Palo Alto,
California.

Item 6.    Indemnification of Directors and Officers.
           -----------------------------------------
           Section  145  of  the  Delaware  General  Corporation  Law  generally
provides that a  corporation  is empowered to indemnify any person who is made a
party to any  threatened,  pending or completed  action,  suit or  proceeding 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,  in any
of such capacities of another corporation or other enterprise, if such director,
officer,  employee  or agent  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 no reasonable  cause to
believe his conduct was unlawful.  This statute describes in detail the right of
PMC to indemnify any such person.

           PMC's   Certificate   of   Incorporation    eliminates   in   certain
circumstances  the liability of directors of PMC for monetary damages for breach
of their  fiduciary  duty as directors.  This  provision  does not eliminate the
liability of a director (i) for breach of the director's  duty of loyalty to PMC
or its  stockholders,  (ii) for acts or  omissions  by the  director not in good
faith or which involve  intentional  misconduct  or a knowing  violation of law,
(iii) for  willful or  negligent  declaration  of an  unlawful  dividend,  stock
purchase or redemption or (iv) for transactions  from which the director derived
an improper personal benefit.

<PAGE>


           PMC's  Certificate  of  Incorporation  also  provides  generally  for
indemnification  of all  directors  and  officers of PMC to the  fullest  extent
permitted by the General Corporation Law of the State of Delaware. Such right to
indemnification  shall be deemed to be a contract  right and includes  generally
the right to be paid by PMC the expenses  incurred in defending  any  proceeding
covered by this provision in advance of its final  disposition.  Individuals who
are entitled to  indemnification  may bring suit to seek recovery of amounts due
under the  foregoing  provisions  and to recover  the  expenses  of such suit if
successful.

           PMC has entered into  indemnification  agreements to such effect with
its officers and  directors  containing  provisions  which are in some  respects
broader than the specific  indemnification  provisions  contained in the General
Corporation  Law of Delaware.  The  indemnification  agreements may require PMC,
among other things,  to indemnify  such officers and directors  against  certain
liabilities  that may arise by reason of their status or service as directors or
officers (other than liabilities  arising from willful  misconduct of a culpable
nature) and to advance  their  expenses  incurred as a result of any  proceeding
against them as to which they could be indemnified.

           PMC believes that it is the position of the  Commission  that insofar
as the  foregoing  provisions  may be invoked to disclaim  liability for damages
arising under the Securities  Act, such  provisions are against public policy as
expressed in the Security Act and are therefore unenforceable.

           PMC  currently  maintains  an  officers'  and  directors'   liability
insurance policy which covers,  subject to the exclusions and limitations of the
policy,  officers and directors of PMC against certain  liabilities which may be
incurred by them solely in such capacities.

Item 7.    Exemption from Registration Claimed.
           -----------------------------------
           Not applicable.

Item 8.    Exhibits.
           ---------
           The Exhibits to this  registration  statement are listed in the Index
to Exhibits on page 5.

Item 9.    Undertakings.
           -------------
           (a)    PMC hereby undertakes:

                  (1)      To file,  during any period in which  offers or sales
                           are being made,  a  post-effective  amendment to this
                           registration   statement   to  include  any  material
                           information  with respect to the plan of distribution
                           not   previously   disclosed   in  the   registration
                           statement or any material change to such  information
                           in the registration statement.

                  (2)      That,  for the purpose of  determining  any liability
                           under the  Securities  Act, each such  post-effective
                           amendment  shall be deemed  to be a new  registration
                           statement relating to the securities offered therein,
                           and the  offering  of such  securities  at that  time
                           shall be deemed to be the initial bona fide  offering
                           thereof.

                  (3)      To   remove   from    registration    by   means   of
                           post-effective  amendment any of the securities being
                           registered  which remain unsold at the termination of
                           the offering.

<PAGE>


           (b)    PMC hereby  undertakes  that, for purposes of determining  any
                  liability  under  the  Securities  Act,  each  filing of PMC's
                  annual  report  pursuant to Section  13(a) or Section 15(d) of
                  the Exchange  Act (and,  where  applicable,  each filing of an
                  employee  benefit  plan's  annual  report  pursuant to Section
                  15(d) of the Exchange Act) that is  incorporated  by reference
                  in the  registration  statement  shall be  deemed  to be a new
                  registration  statement  relating  to the  securities  offered
                  therein,  and the  offering  of such  securities  at that time
                  shall be deemed to be the initial bona fide offering thereof.

           (c)    Insofar as indemnification  for liabilities  arising under the
                  Securities  Act may be  permitted to  directors,  officers and
                  controlling  persons of PMC pursuant to the  Delaware  General
                  Corporation  Law,  the  Certificate  of  Incorporation  or the
                  Bylaws of PMC, Indemnification Agreements entered into between
                  PMC and its officers and directors, or otherwise, PMC has been
                  advised   that  in  the   opinion  of  the   Commission   such
                  indemnification  is against  public policy as expressed in the
                  Securities Act and is, therefore,  unenforceable. In the event
                  that a claim  for  indemnification  against  such  liabilities
                  (other  than the payment by PMC 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 hereunder, PMC will, unless in the
                  opinion  of  its  counsel  the  matter  has  been  settled  by
                  controlling  precedent,  submit  to  a  court  of  appropriate
                  jurisdiction the question whether such  indemnification  by it
                  is against  public policy as expressed in the  Securities  Act
                  and will be governed by the final adjudication of such issue.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.    Incorporation of Documents by Reference.
           --------------------------------------

           The following documents and information are incorporated by reference
as filed with the Securities and Exchange Commission:

           (a)  PMC-Sierra,  Inc.'s  ("PMC's")  Form 10-K Annual  Report for the
                fiscal year ended December 26, 1999 (File No. 000-19084).

           (b)  PMC's Form 8-K dated March 20, 2000 (File No. 000-19084).

           (c)  The  description  of PMC's Common Stock to be offered  hereby is
                contained in the Company's Quarterly Report on Form 10-Q for the
                fiscal  quarter ended on June 27, 1999 filed with the Commission

                amendment  or report  filed for the  purpose  of  updating  such
                description.

           All documents  subsequently  filed by PMC pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended, prior to
the filing of a  post-effective  amendment  which  indicates that all securities
offered  have been  sold or which  deregisters  all  securities  then  remaining
unsold,  shall be deemed to be  incorporated  by reference in this  registration
statement and to be part hereof from the date of filing such documents.

Item 4.    Description of Securities.
           -------------------------
           Not applicable.

Item 5.    Interests of Named Experts and Counsel.
           --------------------------------------
           Certain  legal matters with respect to the shares will be passed upon
by Wilson, Sonsini,  Goodrich & Rosati, a Professional  Corporation,  Palo Alto,
California.

Item 6.    Indemnification of Directors and Officers.
           -----------------------------------------
           Section  145  of  the  Delaware  General  Corporation  Law  generally
provides that a  corporation  is empowered to indemnify any person who is made a
party to any  threatened,  pending or completed  action,  suit or  proceeding 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,  in any
of such capacities of another corporation or other enterprise, if such director,
officer,  employee  or agent  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 no reasonable  cause to
believe his conduct was unlawful.  This statute describes in detail the right of
PMC to indemnify any such person.

           PMC's   Certificate   of   Incorporation    eliminates   in   certain
circumstances  the liability of directors of PMC for monetary damages for breach
of their  fiduciary  duty as directors.  This  provision  does not eliminate the
liability of a director (i) for breach of the director's  duty of loyalty to PMC
or its  stockholders,  (ii) for acts or  omissions  by the  director not in good
faith or which involve  intentional  misconduct  or a knowing  violation of law,
(iii) for  willful or  negligent  declaration  of an  unlawful  dividend,  stock
purchase or redemption or (iv) for transactions  from which the director derived
an improper personal benefit.
PMC's  Certificate  of  Incorporation  also  provides  generally  for
indemnification  of all  directors  and  officers of PMC to the  fullest  extent
permitted by the General Corporation Law of the State of Delaware. Such right to
indemnification  shall be deemed to be a contract  right and includes  generally
the right to be paid by PMC the expenses  incurred in defending  any  proceeding
covered by this provision in advance of its final  disposition.  Individuals who
are entitled to  indemnification  may bring suit to seek recovery of amounts due
under the  foregoing  provisions  and to recover  the  expenses  of such suit if
successful.

           PMC has entered into  indemnification  agreements to such effect with
its officers and  directors  containing  provisions  which are in some  respects
broader than the specific  indemnification  provisions  contained in the General
Corporation  Law of Delaware.  The  indemnification  agreements may require PMC,
among other things,  to indemnify  such officers and directors  against  certain
liabilities  that may arise by reason of their status or service as directors or
officers (other than liabilities  arising from willful  misconduct of a culpable
nature) and to advance  their  expenses  incurred as a result of any  proceeding
against them as to which they could be indemnified.

           PMC believes that it is the position of the  Commission  that insofar
as the  foregoing  provisions  may be invoked to disclaim  liability for damages
arising under the Securities  Act, such  provisions are against public policy as
expressed in the Security Act and are therefore unenforceable.

           PMC  currently  maintains  an  officers'  and  directors'   liability
insurance policy which covers,  subject to the exclusions and limitations of the
policy,  officers and directors of PMC against certain  liabilities which may be
incurred by them solely in such capacities.

Item 7.    Exemption from Registration Claimed.
           -----------------------------------

Item 8.    Exhibits.
           ---------
           The Exhibits to this  registration  statement are listed in the Index
to Exhibits on page 5.

Item 9.    Undertakings.
           -------------
           (a)    PMC hereby undertakes:

                  (1)      To file,  during any period in which  offers or sales
                           are being made,  a  post-effective  amendment to this
                           registration   statement   to  include  any  material
                           information  with respect to the plan of distribution
                           not   previously   disclosed   in  the   registration
                           statement or any material change to such  information
                           in the registration statement.

                  (2)      That,  for the purpose of  determining  any liability
                           under the  Securities  Act, each such  post-effective
                           amendment  shall be deemed  to be a new  registration
                           statement relating to the securities offered therein,
                           and the  offering  of such  securities  at that  time
                           shall be deemed to be the initial bona fide  offering
                           thereof.

                  (3)      To   remove   from    registration    by   means   of
                           post-effective  amendment any of the securities being
                           registered  which remain unsold at the termination of
                           the offering.
(b)    PMC hereby  undertakes  that, for purposes of determining  any
                  liability  under  the  Securities  Act,  each  filing of PMC's
                  annual  report  pursuant to Section  13(a) or Section 15(d) of
                  the Exchange  Act (and,  where  applicable,  each filing of an
                  employee  benefit  plan's  annual  report  pursuant to Section
                  15(d) of the Exchange Act) that is  incorporated  by reference
                  in the  registration  statement  shall be  deemed  to be a new
                  registration  statement  relating  to the  securities  offered
                  therein,  and the  offering  of such  securities  at that time
                  shall be deemed to be the initial bona fide offering thereof.

           (c)    Insofar as indemnification  for liabilities  arising under the
                  Securities  Act may be  permitted to  directors,  officers and
                  controlling  persons of PMC pursuant to the  Delaware  General
                  Corporation  Law,  the  Certificate  of  Incorporation  or the
                  Bylaws of PMC, Indemnification Agreements entered into between
                  PMC and its officers and directors, or otherwise, PMC has been
                  advised   that  in  the   opinion  of  the   Commission   such
                  indemnification  is against  public policy as expressed in the
                  Securities Act and is, therefore,  unenforceable. In the event
                  that a claim  for  indemnification  against  such  liabilities
                  (other  than the payment by PMC 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 hereunder, PMC will, unless in the
                  opinion  of  its  counsel  the  matter  has  been  settled  by
                  controlling  precedent,  submit  to  a  court  of  appropriate
                  jurisdiction the question whether such  indemnification  by it
                  is against  public policy as expressed in the  Securities  Act
                  and will be governed by the final adjudication of such issue.
