                                 INTRODUCTION

   This Proxy Statement is being furnished in connection with the solicitation
of proxies by the Board of Directors ( the "Board" or "Directors") of PIMCO
Commercial Mortgage Securities Trust, Inc. (the "Fund"), a Maryland
corporation, for use at the annual meeting of shareholders of the Fund to be
held at 800 Newport Center Drive, 6th Floor, Newport Beach, California 92660,
on April 12, 2002 at 10:00 a.m., Pacific time, or as adjourned from time to
time (the "Meeting"), for the purposes set forth in the accompanying notice. It
is anticipated that the first mailing of proxies and proxy statements to
shareholders will be on or about March 19, 2002.

   Shareholder Reports.  Shareholders can find important information about the
Fund in the annual report dated December 31, 2001 and the semi-annual report
dated June 30, 2001, each of which previously has been furnished to
shareholders. Shareholders may request another copy of these reports by writing
to the Fund at the above address, or by calling the toll-free telephone number
above.

   The Board is soliciting proxies from shareholders of the Fund with respect
to the following:

    I. To elect Directors to the Board of Directors of the Fund; and

   II. To transact such other business as may properly come before the Meeting.



                      PROPOSAL I:  ELECTION OF DIRECTORS

   The Fund's Articles of Incorporation provide that the Fund's Board of
Directors shall be divided into three classes, as nearly equal in number as
possible, which shall be designated as Class I, Class II and Class III. The
current terms of the Class II Directors expire this year. The current terms of
the Class I and Class III Directors will expire in 2004 and 2003, respectively,
when their respective successors are elected and qualify. The effect of these
staggered terms is to limit the ability of other entities or persons to acquire
control of the Fund by delaying for up to two years the replacement of a
majority of the Board of Directors. J. Michael Hagan, Thomas P. Kemp and Vern
O. Curtis, the current Class II Directors, have been nominated for re-election
by the Board to serve another term, which would expire in 2005 (Messrs. Hagan,
Kemp and Curtis collectively are the "Nominees"). The Nominees have indicated
their willingness to serve as Directors. The Board knows of no reason why the
Nominees would be unable to serve, but in the event of any such unavailability,
the proxies received will be voted for such substituted nominee as the Board
may recommend.

   The persons named as proxies on the enclosed proxy card will vote your
shares for the election of the Nominees unless you withhold authority to vote
for the Nominees in your proxy. If elected by shareholders, the Nominees will
continue to serve as Directors of the Fund until the next meeting of
shareholders, if any, called for the purpose of electing Directors, unless
sooner succeeded as provided in the Fund's Articles of Incorporation. It is
proposed, and the Board recommends, that shareholders elect the Nominees.

                                      2



   The following table sets forth certain information concerning each of the
Directors of the Fund including the Nominees. However, only the Nominees are
standing for election.

   The Class I Directors are:

Board of Directors--Committees

   The Fund has a standing Audit Committee that consists of all of the
independent Directors (Messrs. Babcock, Cannon, Curtis, Hagan, Kemp and
Popejoy). The Audit Committee reviews both the audit and non-audit work of the
Fund's independent public accountant, submits a recommendation to the Board as
to the selection of an independent public accountant, and reviews generally the
maintenance of the Fund's records and the safekeeping arrangements of the
Fund's custodian. During the fiscal year ended December 31, 2001, the Audit
Committee met four times. Each member of the Audit Committee attended 100% of
such meetings during the period in which he was a member of the Audit Committee.

   The Fund adopted an Audit Committee Charter on November 14, 2000, a copy of
which is attached to this Proxy Statement as Appendix A. The Audit Committee
has received written disclosures and the letter required by Independence
Standards Board No. 1 from its independent public accountant, and has discussed
with its independent public accountant its independence. The Audit Committee
has also reviewed and discussed the audited financial statements with Fund
management and its independent public accountant, and discussed certain matters
with its independent public accountant addressed by Statements on Auditing
Standards No. 61. Based on the foregoing, the Audit Committee recommended to
the Board that the Fund's audited financial statements be included in the
Fund's Annual Report for the fiscal year ended December 31, 2001.

   The Board has formed a Valuation Committee whose function is to monitor the
valuation of portfolio securities and other investments and, as required by the
Fund's valuation policies, when the Board is not in session it shall determine
the fair value of portfolio holdings after consideration of all relevant
factors, which determinations shall be reported to the full Board. The
Valuation Committee currently consists of all of the Fund's Board members. The
Valuation Committee held two meetings during the last fiscal year.

   The Fund also has a Nominating Committee, composed of all of the independent
Directors (Messrs. Babcock, Cannon, Curtis, Hagan, Kemp and Popejoy), that is
responsible for the selection and nomination of candidates to serve as
Directors of the Fund. The Nominating Committee does not currently have a
policy regarding whether it will consider nominees recommended by shareholders.
During the fiscal year ended December 31, 2001, there were no meetings of the
Nominating Committee.

Remuneration of Directors and Officers

   The Fund pays each Director who is not an "interested person" of the Fund an
annual retainer of $6,000 plus $1,000 for each regular Board meeting attended
in person and $500 for each meeting attended telephonically, plus reimbursement
of related expenses. In addition, a Director serving as a Committee Chair,
other than those affiliated with PIMCO or its affiliates, receives an
additional annual retainer of $500. For the fiscal year ended December 31,
2001, the Directors who are not "interested persons" of the Fund, as a group,
received compensation in the amount of $70,253.

- --------
/1/ The executive officers of the Fund are appointed annually by the Board.
    They can be reached at the Fund's address above.

Investment Manager and Administrator

   PIMCO is located at 840 Newport Center Drive, Suite 300, Newport Beach,
California 92660. PIMCO serves as the investment manager and the administrator
of the Fund. Subject to the supervision of the Board, PIMCO is responsible for
managing the investment activities of the Fund and the Fund's business affairs
and other administrative matters.

   THE BOARD, INCLUDING THE INDEPENDENT DIRECTORS, RECOMMENDS THAT SHAREHOLDERS
VOTE "FOR" THE NOMINEES UNDER PROPOSAL I. UNMARKED PROXIES WILL BE SO VOTED.

                 INFORMATION ON INDEPENDENT PUBLIC ACCOUNTANT

   PricewaterhouseCoopers LLP was selected by the Board on February 26, 2002 as
independent public accountant to examine the financial statements of the Fund
for the fiscal year ending December 31, 2002. A representative of
PricewaterhouseCoopers LLP, if requested by any shareholder, will be present
(via telephone) at the Meeting to respond to appropriate questions from
shareholders.

Audit Fees

   The aggregate fees paid to PricewaterhouseCoopers LLP in connection with the
annual audit of the Fund for the fiscal year ended December 31, 2001 was
$12,800.

Financial Information Systems Design and Implementation Fees

   There were no fees billed for financial information systems design and
implementation services rendered by PricewaterhouseCoopers LLP to the Fund, its
investment adviser, and entities controlling,

                                      11



controlled by or under common control with the investment adviser that provide
services to the Fund for the fiscal year ended December 31, 2001.

All Other Fees

   The aggregate fees billed for all other non-audit services, including fees
for tax-related services, rendered by PricewaterhouseCoopers LLP to the Fund,
its investment adviser, and entities controlling, controlled by or under common
control with the investment adviser that provide services to the Fund for the
fiscal year ended December 31, 2001 was $905,395. The Audit Committee has
considered whether the provision of non-audit services is compatible with
maintaining the independence of PricewaterhouseCoopers LLP.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

   Section 16(a) of the Securities Exchange Act of 1934, as amended, and
Section 30(h) of the 1940 Act require the Fund's Officers and Directors,
investment adviser, affiliates of the investment adviser, and persons who
beneficially own more than ten percent of a registered class of the Fund's
securities ("Reporting Persons"), to file reports of ownership of the Fund's
securities and changes in ownership with the Securities and Exchange Commission
and the New York Stock Exchange. Reporting Persons are also required by such
regulations to furnish the Fund with copies of all Section 16(a) forms they
file.

   Based solely on its review of the copies of such forms received by it and
written representation of certain Reporting Persons, the Fund believes that
during fiscal year 2001, its Reporting Persons complied with all applicable
filing requirements.

                                OTHER BUSINESS

   The Directors do not know of any matters to be presented at the Meeting
other than those set forth in this proxy statement. If other business should
properly come before the Meeting, proxies will be voted in accordance with the
judgment of the persons named in the accompanying proxy.

                            ADDITIONAL INFORMATION

Expenses

   The expense of preparing, printing and mailing the enclosed form of proxy
and accompanying Notice and Proxy Statement will be borne by the Fund. The Fund
will reimburse banks, brokers and others for their reasonable expenses in
forwarding proxy solicitation material to the beneficial owners of the shares
of the Fund. In order to obtain the necessary quorum at the Meeting,
supplementary solicitation may be made by mail, telephone, the Internet or
personal interview by officers or agents of the Fund.

Quorum and Votes Required

   Shareholders of record at the close of business on March 8, 2002 (the
"Record Date") are entitled to notice of, and to vote at, the Meeting. Each
shareholder is entitled to one vote for each full share and an appropriate
fraction of a vote for each fractional share held.

   As of the Record Date, 11,053,539 shares of the Fund, representing the same
number of votes, were outstanding. As of December 31, 2001, no persons owned of
record or beneficially 5% or more of the shares of the Fund.

                                      12



   Timely and properly executed proxies will be voted as instructed by
shareholders. A shareholder may revoke his or her proxy at any time prior to
its exercise by written notice addressed to the Secretary of the Fund at
840 Newport Center Drive, Suite 300, Newport Beach, California 92660, or by
voting in person at the Meeting. However, attendance in person at the Meeting,
by itself, will not revoke a previously tendered proxy.

   The presence in person or by proxy of the holders of a majority of the
outstanding shares is required to constitute a quorum at the Meeting. Shares
held by shareholders present in person or represented by proxy at the Meeting
will be counted both for the purpose of determining the presence of a quorum
and for calculating the votes cast on the issues before the Meeting.
Abstentions will also be counted for quorum purposes.

   Proxies that reflect abstentions or broker "non-votes" (that is, shares held
by brokers or nominees as to which (a) instructions have not been received from
the beneficial owner or other persons entitled to vote and (b) the brokers or
nominees do not have discretionary voting power on a particular matter) will be
counted as shares that are present and entitled to vote for purposes of
determining the presence of a quorum. Pursuant to the rules and policies of the
New York Stock Exchange (the "Exchange"), members of the Exchange may vote on
the proposals to be considered at the Meeting without instructions from the
beneficial owners of the Fund's shares.

   In the event that a quorum is present at the Meeting but sufficient votes to
approve any proposal are not received, the persons named as proxies may propose
one or more adjournment of the Meeting to permit further solicitation of
proxies or to obtain the vote required for approval of one or more proposals.
Any such adjournment will require the affirmative vote of a majority of those
shares represented at the Meeting in person or by proxy. If a quorum is
present, the persons named as proxies will vote those proxies which they are
entitled to vote FOR the proposal in favor of such an adjournment and will vote
those proxies required to be voted AGAINST the proposal against any such
adjournment. A shareholder vote may be taken prior to any adjournment of the
Meeting on any proposal for which there is sufficient votes for approval, even
though the Meeting is adjourned as to other proposals.

Voting

   To vote, shareholders may sign and mail the proxy card received with the
proxy statement or attend the Meeting in person.

Required Vote

   Election of the Directors (Proposal I) will require the affirmative vote of
the holders of a majority of the Fund's shares present (or represented by
proxy) and voting at the Meeting.

Shareholders' Proposals

   The Fund holds annual meetings of shareholders. A shareholder's proposal
that is intended to be presented at the Fund's Annual Meeting of Shareholders
in 2003 must have been received by the Fund a reasonable time before the
mailing of the proxy statement in order to be included in the Fund's proxy

                                      13



statement and form of proxy relating to the meeting. A shareholder who wishes
to make a proposal at the 2003 annual meeting of shareholders without including
the proposal in the Fund's proxy statement must notify the Fund in writing, at
the Fund's offices, of such proposal no later than 60 days before the meeting.
If a shareholder fails to give timely notice, then the persons named as proxies
in the proxies solicited by the Board for the 2003 annual meeting of
shareholders may exercise discretionary voting power with respect to any such
proposal.

   To ensure the presence of a quorum at the Meeting, prompt execution and
return of the enclosed proxy is requested. A self-addressed, postage-paid
envelope is enclosed for your convenience.

                            AUDIT COMMITTEE CHARTER

1. The Audit Committee of the Fund shall be composed of independent members of
   the Board of Directors of the Fund (the "Board). Each of these independent
   members of the Board shall be financially literate and at least one shall
   have accounting or related financial management expertise, as determined by
   the Board.

2. The purposes of the Audit Committee are:

   outside auditor ultimately is accountable to the Board and the Audit
   Committee. The function of the Audit Committee is oversight. To this end,
   the Audit Committee shall have unrestricted access to the Fund's Board, the
   independent auditors, and the executive and financial management of the Fund.

3. To carry out its purposes, the Audit Committee shall have the following
   duties and responsibilities:

   (a) to recommend the selection, retention or termination of auditors and, in
       connection therewith, to evaluate the independence of the auditors,
       including whether the auditors provide any consulting services to PIMCO,
       and to receive the auditors' specific representations as to their
       independence;

   (b) to meet at least annually with the Fund's independent auditors,
       including private meetings (i) to review the arrangements for,
       procedures to be utilized, and scope of the annual audit and any special
       audits; (ii) to discuss any matters of concern relating to the Fund's
       financial statements, including any adjustments to such statements
       recommended by the auditors, or other results of audit(s); (iii) to
       review the annual financial statements of the Fund and significant
       accounting policies underlying the statements and their presentation to
       the public in the Annual Report and Form N-SAR; (iv) to consider the
       auditors' comments with respect to the Fund's financial policies,
       procedures and internal accounting controls and PIMCO's responses
       thereto; and (v) to review the form of opinion the auditors propose to
       render to the Board and shareholders;

   (c) to consider the effect upon the Fund of any changes in accounting
       principles or practices proposed by PIMCO or the auditors;

   (d) to review the form of opinion that the auditors propose to submit to the
       Board and shareholders;

                                      A-1



   (e) to ensure that the outside auditor submits periodically to the Committee
       a formal written statement delineating all relationships between the
       auditor and the Fund; to actively engage in a dialogue with the outside
       auditor with respect to any disclosed relationships or services that may
       impact the objectivity and independence of the outside auditor; and to
       recommend that the Board take appropriate action in response to the
       auditor's report to satisfy itself of the outside auditors' independence;

   (f) to review the fees charged by the auditors for audit and non-audit
       services;

   (g) to investigate improprieties or suspected improprieties in Fund
       operations; and

   (h) to report its activities to the full Board on a regular basis and to
       make such recommendations with respect to the above and other matters as
       the Committee may deem necessary or appropriate.

4. The Committee shall meet regularly, and shall call special meetings when
   necessary.

5. The Committee shall meet with the Treasurer of the Fund and service
   providers when necessary, including internal auditors, if any, from PIMCO.

6. The Committee shall have the resources and authority appropriate to
   discharge its responsibilities, including the authority to retain, at the
   Fund's expense, special counsel and other experts or consultants when
   necessary.

7. The Committee shall review this Charter and recommend any changes to the
   full Board annually.
