                                EXPLANATORY NOTE

         Pan American Silver Corp. (the "Registrant") is filing this Amendment
No. 1 to its Annual Report on Form 40-F for the fiscal year ended December 31,
2004 solely to disclose, as required by the rules of the Nasdaq Stock Market,
Inc. ("Nasdaq"), that the Registrant followed British Columbia practice with
respect to its quorum requirements in lieu of those required by Nasdaq for the
years ended December 31, 2004 and 2003. Therefore, the paragraph titled "J.
Nasdaq Exemptions" has been amended to read in its entirety as set forth below.

J.       Nasdaq Exemptions

         On March 16, 2005, the Registrant informed the Nasdaq National Market
that as permitted by Rule 4350(a)(1) of the Nasdaq Marketplace Rules, it
intended to follow British Columbia practice with respect to quorum
requirements in lieu of those required by Rule 4350(f) of the Nasdaq
Marketplace Rules (which provides that a quorum for a shareholder meeting of a
Nasdaq-listed company must be at least 33-1/3% of the outstanding common shares
of the company). The Registrant has followed such British Columbia practice for
the years ended December 31, 2004 and 2003 pursuant to an exemption granted by
the Nasdaq National Market. The Registrant's by-laws provide that the minimum
quorum for a meeting of shareholders of Common Shares is two individuals who
are shareholders, proxy holders or duly authorized representatives of corporate
shareholders personally present and representing shares aggregating not less
than 5% of the issued shares of the Registrant carrying the right to vote. The
Registrant's quorum requirements are not prohibited by the requirements of the
Business Corporations Act (British Columbia) and the Registrant intends to
continue to comply with the requirements of the Business Corporations Act
(British Columbia). The rules of the Toronto Stock Exchange, upon which the
Common Shares are also listed, do not contain specific quorum requirements.



                 UNDERTAKING AND CONSENT TO SERVICE OF PROCESS

A.       Undertaking

         The Registrant undertakes to make available, in person or by
telephone, representatives to respond to inquiries made by the Commission
staff, and to furnish promptly, when requested to do so by the Commission
staff, information relating to: the securities in relation to which the
obligation to file an annual report on Form 40-F arises; or transactions in
said securities.

B.       Consent to Service of Process

         The Registrant has previously filed with the Commission a Form F-X in
connection with its Common Shares.



                                   SIGNATURE

         Pursuant to the requirements of the Exchange Act, the Registrant
certifies that it meets all of the requirements for filing on Form 40-F and has
duly caused this amendment to its annual report to be signed on its behalf by
the undersigned, thereto duly authorized.


                                           PAN AMERICAN SILVER CORP.
