ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     PCI Canada is a wholly-owned subsidiary of PAAC. PAAC, which is a Delaware
corporation, is empowered by the Delaware General Corporation Law, subject to
the procedures and limitations stated therein, to indemnify any person against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with any
threatened, pending or completed action, suit or proceeding in which such person
is made a party by reason of his being or having been a director, officer,
employee or agent of PAAC. The statute provides that indemnification pursuant to
its provisions is not exclusive of other rights of indemnification to which a
person may be entitled under any by-law, agreement, vote of stockholders or
disinterested directors, or otherwise. The Certificate of Incorporation and
by-laws of PAAC provide for indemnification of the directors and officers of
such entities to the full extent permitted by the Delaware General Corporation
Law.

incurred by any of them in certain stated proceedings and under certain stated
conditions.

SCHEDULE II -- VALUATION AND QUALIFYING ACCOUNTS.
 
     All other schedules have been omitted because they are not applicable or
not required or the required information is included in the financial statements
or notes thereto.
 
ITEM 22. UNDERTAKINGS.
 
     The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act, each filing of PAAC's annual
report pursuant to section 13(a) or section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to section 15(d) of the Exchange Act) 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of Registrants
pursuant to the provisions, described under Item 20 above, or otherwise, the
Registrants have been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants 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 Registrants will, unless in
the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by them is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     The undersigned Registrants hereby undertake that:
 
     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or 497(h) under
the Securities Act shall be deemed to be part of this registration statement as
of the time it was declared effective.
 
     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus 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.
 
     The undersigned Registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of
 
                                      II-5

receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.
 
     The undersigned Registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in this Registration Statement when it became effective.

behalf by the undersigned, thereunto duly authorized, in the City of Houston,
State of Texas, on the 8th day of January, 1998.
