ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

       Not applicable.

ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

       Section 17-108 of the Delaware Revised Uniform Limited Partnership Act,
as amended (the "Partnership Act"), gives a limited partnership the power to
indemnify and hold harmless any partner or any other person against any and all
claims and demands whatsoever, subject to any standards and restrictions set
forth in its partnership agreement.

       Certain current and former executive officers of the Partnership and
directors and officers of Thomson Advisory Group Inc. ("TAG Inc.") and Thomson
McKinnon Asset Management Inc., the former general partners of the Partnership,
and the Partnership's affiliated broker/dealer, PIMCO Advisors Distribution
Company ("PADCo"), are parties to indemnification agreements with the
Partnership pursuant to which the Partnership has agreed, to the fullest extent
permitted by law, to indemnify such persons from and against, among other
things, all losses, claims, liabilities, expenses and other amounts arising from
any and all claims, actions or proceedings in which any such person may be
involved by reason of his or her status as an officer of the Partnership or in
connection with such person's services.

       In accordance with Section 17-108, the Partnership Agreement generally
provides that each officer, director or the equivalent of the Partnership shall
be indemnified by the Partnership against any and all losses, claims, damages,
liabilities and expenses arising from proceedings in which any such person may
be involved by reason of his or her status and further shall be advanced
expenses in defending any such proceeding to the fullest extent permitted by
law.  The Partnership will not be permitted to change the indemnification
provisions of the Partnership Agreement for at least six years following the
repurchase of TAG Inc. common stock as set forth in the Stock Repurchase
Agreement (defined below).

       The TAG Inc. Stock Purchase and Exchange Agreement dated July 11, 1994
(the "Stock Purchase Agreement") provides that PIMCO Partners, G.P. ("PIMCO
GP"), the Partnership's current general partner, shall indemnify those persons
serving as directors of TAG Inc. immediately prior to the purchases and
exchanges of TAG Inc. common stock thereunder against all claims, liabilities
and expenses incurred in connection with their approval of such purchases or
exchanges.  The Stock Purchase Agreement also provides that PIMCO GP shall cause
TAG Inc. and the Partnership to maintain liability insurance policies naming as
beneficiaries the directors of TAG Inc.  In addition, TAG Inc.'s by-laws provide
that each of its directors and officers shall be indemnified by TAG Inc. against
expenses incurred in connection with legal proceedings in which any such
director or officer is involved by reason of such office.  TAG Inc. will not be
permitted to change the indemnification provisions of its by-laws for at least
six years following the repurchase of TAG Inc. common stock.

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 Securities Act of 1933;

              (ii)   To reflect in the prospectus any facts or events arising
                     after the effective date of the 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 the Registration
                     Statement;

              (iii)  To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     Registration Statement or any material change in such
                     information in the Registration Statement;

              Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) shall
              ------------------                                               
          not apply if the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed by the Registrant pursuant to Section 13 or Section
          15(d) of the Securities Exchange Act of 1934 that are incorporated by
          reference in the Registration Statement.

          (2) That, for the purpose of determining any liability under the
          Securities Act of 1933, 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 a post-effective amendment
          any of the securities being registered which remain unsold at the
          termination of the offering.

     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 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 of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

ITEM 6.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

       Section 17-108 of the Delaware Revised Uniform Limited Partnership Act,
as amended (the "Partnership Act"), gives a limited partnership the power to
indemnify and hold harmless any partner or any other person against any and all
claims and demands whatsoever, subject to any standards and restrictions set
forth in its partnership agreement.

       Certain current and former executive officers of the Partnership and
directors and officers of Thomson Advisory Group Inc. ("TAG Inc.") and Thomson
McKinnon Asset Management Inc., the former general partners of the Partnership,
and the Partnership's affiliated broker/dealer, PIMCO Advisors Distribution
Company ("PADCo"), are parties to indemnification agreements with the
Partnership pursuant to which the Partnership has agreed, to the fullest extent
permitted by law, to indemnify such persons from and against, among other
things, all losses, claims, liabilities, expenses and other amounts arising from
any and all claims, actions or proceedings in which any such person may be
involved by reason of his or her status as an officer of the Partnership or in
connection with such person's services.

       In accordance with Section 17-108, the Partnership Agreement generally
provides that each officer, director or the equivalent of the Partnership shall
be indemnified by the Partnership against any and all losses, claims, damages,
liabilities and expenses arising from proceedings in which any such person may
be involved by reason of his or her status and further shall be advanced
expenses in defending any such proceeding to the fullest extent permitted by
law.  The Partnership will not be permitted to change the indemnification
provisions of the Partnership Agreement for at least six years following the
repurchase of TAG Inc. common stock as set forth in the Stock Repurchase
Agreement (defined below).

       The TAG Inc. Stock Purchase and Exchange Agreement dated July 11, 1994
(the "Stock Purchase Agreement") provides that PIMCO Partners, G.P. ("PIMCO
GP"), the Partnership's current general partner, shall indemnify those persons
serving as directors of TAG Inc. immediately prior to the purchases and
exchanges of TAG Inc. common stock thereunder against all claims, liabilities
and expenses incurred in connection with their approval of such purchases or
exchanges.  The Stock Purchase Agreement also provides that PIMCO GP shall cause
TAG Inc. and the Partnership to maintain liability insurance policies naming as
beneficiaries the directors of TAG Inc.  In addition, TAG Inc.'s by-laws provide
that each of its directors and officers shall be indemnified by TAG Inc. against
expenses incurred in connection with legal proceedings in which any such
director or officer is involved by reason of such office.  TAG Inc. will not be
permitted to change the indemnification provisions of its by-laws for at least
six years following the repurchase of TAG Inc. common stock.

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 Securities Act of 1933;

              (ii)   To reflect in the prospectus any facts or events arising
                     after the effective date of the 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 the Registration
                     Statement;

              (iii)  To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     Registration Statement or any material change in such
                     information in the Registration Statement;

              Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) shall
              ------------------                                               
          not apply if the information required to be included in a post-
          effective amendment by those paragraphs is contained in periodic
          reports filed by the Registrant pursuant to Section 13 or Section
          15(d) of the Securities Exchange Act of 1934 that are incorporated by
          reference in the Registration Statement.

          (2) That, for the purpose of determining any liability under the
          Securities Act of 1933, 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 a post-effective amendment
          any of the securities being registered which remain unsold at the
          termination of the offering.

     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 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.

                                     - 6 -
(c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.

                                     - 7 -
