                 Statement  which are held by former  directors of StarSight for
                 the benefit of the  Company.  These  options do not entitle the
                 Company to vote on any matter  submitted  to a vote of Issuer's
                 shareholders.

Gemstar International Group Limited
135 North Los Robles Avenue - Suite 800
Pasadena, California  91101

Ladies and Gentlemen:

     I have been  advised  that as of the date of this letter I may be deemed to
be an "affiliate" of StarSight  Telecast,  Inc., a California  corporation  (the
"Company"),  as the term  "affiliate"  is (i) defined within the meaning of Rule
145 of the rules and regulations (the "Rules and Regulations") of the Securities
and Exchange  Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"),  and/or (ii) used in and for purposes of Accounting  Series
Releases 130 and 135, as amended,  of the  Commission.  Pursuant to the terms of
the   Agreement  and  Plan  of  Merger  dated  as  of  December  23,  1996  (the
"Agreement"),  among  Gemstar  International  Group  Limited,  a British  Virgin
Islands  corporation  ("Parent"),   G/S  Acquisition  Subsidiary,  a  California
corporation  ("Sub"),  and the  Company,  Sub will be  merged  with and into the
Company (the "Merger").

     In connection with the Merger,  I am entitled to receive  ordinary  shares,
par value $.01 per share, of Parent (the "Parent Shares") in exchange for shares
(or options or warrants for shares)  owned by me of capital stock of the Company
(the "Company Shares").

     I represent, warrant and covenant to Parent that in the event I receive any
Parent Shares as a result of the Merger:

     (a)  I shall not make any sale, transfer or other disposition of the Parent
          Shares in violation of the Act or the Rules and Regulations.

     (b)  I have  carefully read this letter and the Agreement and discussed the
          requirements of such documents and other  applicable  limitations upon
          my ability to sell, transfer or otherwise dispose of Parent Shares, to
          the  extent I felt  necessary,  with my  counsel  or  counsel  for the
          Company.

     (c)  I have been advised that the issuance of Parent  Shares to me pursuant
          to the Merger will be registered with the Commission  under the Act on
          a  Registration  Statement on Form F-4.  However,  because I have been
          advised  that,  at the time the Merger is submitted  for a vote of the
          shareholders  of the Company (a) I may be deemed to be an affiliate of
          the  Company  and (b) other  than as set forth in the  Agreement,  the
          distribution by me of the Parent Shares has not been registered  under
          the Act,  I will not sell,  transfer  or  otherwise  dispose of Parent
          Shares  issued to me in the Merger  unless (i) such sale,  transfer or
          other  disposition  is  effected  in  compliance  with the  applicable
          requirements of Rule 145 promulgated by the Commission  under the Act,
          (ii) such sale,  transfer or other  disposition has been made pursuant
          to an effective  registration  statement under the Act or (iii) in the



                                 Page 17 of 22





          opinion of counsel reasonably  acceptable to Parent or as described in
          a "no-action" or interpretive letter from the staff of the Commission,
          such sale,  transfer or other  disposition  is  otherwise  exempt from
          registration under the Act.

     (d)  I  understand   that  Parent,   except  as  provided  by   contractual
          arrangement  existing on the date hereof,  is under no obligation,  to
          register the sale,  transfer or other disposition of the Parent Shares
          by me or on my  behalf  under  the Act or,  except as set forth in the
          following  paragraph,  to take any other action  necessary in order to
          make  compliance  with an exemption from such  registration  available
          solely as a result of the Merger.

          From and after the Effective  Time of the Merger and for so long as is
     necessary  in  order to  permit  me to sell the  Parent  shares  held by me
     pursuant  to Rule 145 and,  to the  extent  applicable,  Rule 144 under the
     Securities Act, Parent will file on a timely basis all reports  required to
     be filed by it pursuant to the Securities Exchange Act of 1934, as amended,
     and the rules and regulations thereunder, as the same shall be in effect at
     the time,  referred to in  paragraph  (c) of Rule 144 under the  Securities
     Act, in order to permit me to sell,  transfer or  otherwise  dispose of the
     Parent  Shares held by me pursuant to the terms and  conditions of Rule 145
     and the applicable provisions of Rule 144.

     (e)  I also  understand that there will be placed on the  certificates  for
          the  Parent  Shares  issued to me, or any  substitutions  therefor,  a
          legend stating in substance:

               THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  WERE  ISSUED IN A
               TRANSACTION  TO WHICH RULE 145  PROMULGATED  UNDER THE SECURITIES
               ACT OF 1933 APPLIES.  THE SHARES  REPRESENTED BY THIS CERTIFICATE
               MAY  ONLY BE  TRANSFERRED  IN  ACCORDANCE  WITH  THE  TERMS OF AN
               AGREEMENT  DATED DECEMBER 23, 1996 BETWEEN THE REGISTERED  HOLDER
               HEREOF AND GEMSTAR  INTERNATIONAL  GROUP  LIMITED A COPY OF WHICH
               AGREEMENT  IS  ON  FILE  AT  THE  PRINCIPAL  OFFICES  OF  GEMSTAR
               INTERNATIONAL GROUP LIMITED.

     (f)  I also understand that unless a sale or transfer is made in conformity
          with  the  provisions  of  Rule  145 or Rule  144,  or  pursuant  to a
          registration statement, Parent reserves the right to put the following
          legend on the certificates issued to my transferee:

               THE  SHARES   REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
               REGISTERED  UNDER THE  SECURITIES  ACT OF 1933 AND WERE  ACQUIRED
               FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION  TO WHICH
               RULE 145  PROMULGATED  UNDER THE  SECURITIES ACT OF 1933 APPLIES.
               THE SHARES  HAVE BEEN  ACQUIRED BY THE HOLDER NOT WITH A VIEW TO,
               OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN
               THE  MEANING OF THE  SECURITIES  ACT OF 1933 AND MAY NOT BE SOLD,
               PLEDGED OR OTHERWISE  TRANSFERRED  EXCEPT IN  ACCORDANCE  WITH AN
               EXEMPTION FROM THE  REGISTRATION  REQUIREMENTS  OF THE SECURITIES
               ACT OF 1933.

     It is understood  and agreed that the legends set forth in  paragraphs  (e)
and (f) above shall be removed by delivery of  substitute  certificates  without
such legend if the undersigned shall have delivered to Parent a copy of a letter


                                 Page 18 of 22








from  the  staff  of  the  Commission,  or  an  opinion  of  counsel  reasonably
satisfactory to Parent in form and substance reasonably  satisfactory to Parent,
to the effect that such legend is not required for purposes of the Act.

     In connection with the proposed  Merger, I wish to inform you that I do not
have  any  present  commitment,  plan or  intention  to  sell  (or  engage  in a
risk-reducing or other  arrangement which would be treated as a sale for federal
income tax purposes),  transfer or otherwise dispose of any of my Company Shares
prior to and in  contemplation  of the Merger or any of the Parent Shares I will
receive in the Merger.  I further  agree that I will not offer to sell,  sell or
otherwise  dispose of any of the Parent  Shares in violation of the Act or offer
to sell,  sell or  otherwise  dispose of any of my Company  Shares  (other  than
through conversion to Parent's Shares in the Merger) or any of the Parent Shares
received by me in the Merger  until such time as financial  results  covering at
least 30 days of post-merger combined operations have been published, whether by
issuance  of a  quarterly  earnings  report on Form  10-Q or Form 6-K,  or other
applicable  form,  or other  public  issuance  (such as a press  release)  which
includes such information.  Notwithstanding  the foregoing,  I understand that I
will not be  prohibited  from selling up to 10% of the shares I hold at the time
of the Merger during the  aforementioned  period if the requirements of Rule 145
are complied with.

     If the Merger  Agreement were to be terminated  prior to the Effective Time
in accordance with its terms, this letter Agreement and my obligations hereunder
will also terminate concurrently with the termination of the Merger Agreement.

     Execution of this letter  should not be  considered an admission on my part
that I am an "affiliate"  of the Company as described in the first  paragraph of
this letter, or as a waiver of any rights I may have to object to any claim that
I am such an affiliate on or after the date of this letter.

                                       Very truly yours,

                                       PVI TRANSMISSION INC.

Gemstar International Group Limited
135 North Los Robles Avenue - Suite 800
Pasadena, California  91101

Ladies and Gentlemen:

     I have been  advised  that as of the date of this letter I may be deemed to
be an "affiliate" of StarSight  Telecast,  Inc., a California  corporation  (the
"Company"),  as the term  "affiliate"  is (i) defined within the meaning of Rule
145 of the rules and regulations (the "Rules and Regulations") of the Securities
and Exchange  Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"),  and/or (ii) used in and for purposes of Accounting  Series
Releases 130 and 135, as amended,  of the  Commission.  Pursuant to the terms of
the   Agreement  and  Plan  of  Merger  dated  as  of  December  23,  1996  (the
"Agreement"),  among  Gemstar  International  Group  Limited,  a British  Virgin
Islands  corporation  ("Parent"),   G/S  Acquisition  Subsidiary,  a  California
corporation  ("Sub"),  and the  Company,  Sub will be  merged  with and into the
Company (the "Merger").

     In connection with the Merger,  I am entitled to receive  ordinary  shares,
par value $.01 per share, of Parent (the "Parent Shares") in exchange for shares
(or options or warrants for shares)  owned by me of capital stock of the Company
(the "Company Shares").

     I represent, warrant and covenant to Parent that in the event I receive any
Parent Shares as a result of the Merger:

     (a)  I shall not make any sale, transfer or other disposition of the Parent
          Shares in violation of the Act or the Rules and Regulations.

     (b)  I have  carefully read this letter and the Agreement and discussed the
          requirements of such documents and other  applicable  limitations upon
          my ability to sell, transfer or otherwise dispose of Parent Shares, to
          the  extent I felt  necessary,  with my  counsel  or  counsel  for the
          Company.

     (c)  I have been advised that the issuance of Parent  Shares to me pursuant
          to the Merger will be registered with the Commission  under the Act on
          a  Registration  Statement on Form F-4.  However,  because I have been
          advised  that,  at the time the Merger is submitted  for a vote of the
          shareholders  of the Company (a) I may be deemed to be an affiliate of
          the  Company  and (b) other  than as set forth in the  Agreement,  the
          distribution by me of the Parent Shares has not been registered  under
          the Act,  I will not sell,  transfer  or  otherwise  dispose of Parent
          Shares  issued to me in the Merger  unless (i) such sale,  transfer or
          other  disposition  is  effected  in  compliance  with the  applicable
          requirements of Rule 145 promulgated by the Commission  under the Act,
          (ii) such sale,  transfer or other  disposition has been made pursuant
          to an effective  registration  statement under the Act or (iii) in the
          opinion of counsel reasonably  acceptable to Parent or as described in
          a "no-action" or interpretive letter from the staff of the Commission,



                                 Page 20 of 22





          such sale,  transfer or other  disposition  is  otherwise  exempt from
          registration under the Act.

     (d)  I  understand   that  Parent,   except  as  provided  by   contractual
          arrangement  existing on the date hereof,  is under no obligation,  to
          register the sale,  transfer or other disposition of the Parent Shares
          by me or on my  behalf  under  the Act or,  except as set forth in the
          following  paragraph,  to take any other action  necessary in order to
          make  compliance  with an exemption from such  registration  available
          solely as a result of the Merger.

          From and after the Effective  Time of the Merger and for so long as is
     necessary  in  order to  permit  me to sell the  Parent  shares  held by me
     pursuant  to Rule 145 and,  to the  extent  applicable,  Rule 144 under the
     Securities Act, Parent will file on a timely basis all reports  required to
     be filed by it pursuant to the Securities Exchange Act of 1934, as amended,
     and the rules and regulations thereunder, as the same shall be in effect at
     the time,  referred to in  paragraph  (c) of Rule 144 under the  Securities
     Act, in order to permit me to sell,  transfer or  otherwise  dispose of the
     Parent  Shares held by me pursuant to the terms and  conditions of Rule 145
     and the applicable provisions of Rule 144.

     (e)  I also  understand that there will be placed on the  certificates  for
          the  Parent  Shares  issued to me, or any  substitutions  therefor,  a
          legend stating in substance:

               THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  WERE  ISSUED IN A
               TRANSACTION  TO WHICH RULE 145  PROMULGATED  UNDER THE SECURITIES
               ACT OF 1933 APPLIES.  THE SHARES  REPRESENTED BY THIS CERTIFICATE
               MAY  ONLY BE  TRANSFERRED  IN  ACCORDANCE  WITH  THE  TERMS OF AN

               AGREEMENT  IS  ON  FILE  AT  THE  PRINCIPAL  OFFICES  OF  GEMSTAR
               INTERNATIONAL GROUP LIMITED.

     (f)  I also understand that unless a sale or transfer is made in conformity
          with  the  provisions  of  Rule  145 or Rule  144,  or  pursuant  to a
          registration statement, Parent reserves the right to put the following
          legend on the certificates issued to my transferee:

               THE  SHARES   REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN

               FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION  TO WHICH
               RULE 145  PROMULGATED  UNDER THE  SECURITIES ACT OF 1933 APPLIES.
               THE SHARES  HAVE BEEN  ACQUIRED BY THE HOLDER NOT WITH A VIEW TO,
               OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN
               THE  MEANING OF THE  SECURITIES  ACT OF 1933 AND MAY NOT BE SOLD,
               PLEDGED OR OTHERWISE  TRANSFERRED  EXCEPT IN  ACCORDANCE  WITH AN
               EXEMPTION FROM THE  REGISTRATION  REQUIREMENTS  OF THE SECURITIES
               ACT OF 1933.

     It is understood  and agreed that the legends set forth in  paragraphs  (e)
and (f) above shall be removed by delivery of  substitute  certificates  without
such legend if the undersigned shall have delivered to Parent a copy of a letter
from  the  staff  of  the  Commission,  or  an  opinion  of  counsel  reasonably

     In connection with the proposed  Merger, I wish to inform you that I do not

least 30 days of post-merger combined operations have been published, whether by
issuance  of a  quarterly  earnings  report on Form  10-Q or Form 6-K,  or other
applicable  form,  or other  public  issuance  (such as a press  release)  which
includes such information.  Notwithstanding  the foregoing,  I understand that I
will not be  prohibited  from selling up to 10% of the shares I hold at the time
of the Merger during the  aforementioned  period if the requirements of Rule 145
are complied with.

     If the Merger  Agreement were to be terminated  prior to the Effective Time
in accordance with its terms, this letter Agreement and my obligations hereunder
will also terminate concurrently with the termination of the Merger Agreement.

     Execution of this letter  should not be  considered an admission on my part
that I am an "affiliate"  of the Company as described in the first  paragraph of
this letter, or as a waiver of any rights I may have to object to any claim that
I am such an affiliate on or after the date of this letter.
