securities equal to the number of shares of Spectrian California Common Stock so
reserved immediately prior to the Effective Date of the Merger.

holder of an outstanding certificate representing shares of Spectrian California
Common  Stock  may,  at  such  stockholder's  option,  surrender  the  same  for
cancellation to Chase Mellon Shareholder  Services,  Inc. as exchange agent (the
"Exchange Agent"), and each such holder shall be entitled to receive in exchange
therefor a certificate or certificates  representing the number of shares of the
Surviving  Corporation's  Common  Stock  into  which  such  holders'  shares  of
Spectrian California Common Stock were converted as herein provided.  Unless and
until so surrendered,  each  outstanding  certificate  theretofore  representing
shares of Spectrian  California Common Stock shall be deemed for all purposes to
represent the number of whole shares of the Surviving Corporation's Common Stock
into which such shares of Spectrian  California  Common Stock were  converted in
the Merger.

   The registered owner on the books and records of the Surviving Corporation or
the  Exchange  Agent of any  shares  of stock  represented  by such  outstanding
certificate  shall,  until  such  certificate  shall have been  surrendered  for
transfer or conversion or otherwise  accounted for to the Surviving  Corporation
or the  Exchange  Agent,  have and be entitled to exercise  any voting and other
rights with respect to and to receive dividends and other distributions upon the
shares  of  Common  Stock  of the  Surviving  Corporation  represented  by  such
outstanding certificate as provided above.

   Each certificate  representing  Common Stock of the Surviving  Corporation so
issued in the Merger shall bear the same  legends,  if any,  with respect to the
restrictions on transferability as the certificates of 

                                        3


Spectrian  California  so  converted  and  given in  exchange  therefor,  unless
otherwise  determined by the Board of Directors of the Surviving  Corporation in
compliance with applicable laws.

   If any certificate for shares of Spectrian  Delaware stock is to be issued in
a name other than that in which the certificate surrendered in exchange therefor
is registered,  it shall be a condition of issuance thereof that the certificate
so  surrendered  shall be properly  endorsed  and  otherwise  in proper form for
transfer,  that such transfer otherwise be proper and that the person requesting
such  transfer pay to Spectrian  Delaware or the Exchange  Agent any transfer or
other taxes payable by reason of the issuance of such new  certificate in a name
other  than that of the  registered  holder of the  certificate  surrendered  or
establish to the satisfaction of Spectrian  Delaware that such tax has been paid
or is not payable.
