 PMC International, Inc.
 
                                 INTRODUCTION
 
  ZACQ Corp., a Colorado corporation (the "Offeror") and a wholly-owned
subsidiary of The Ziegler Companies, Inc., a Wisconsin corporation (the
"Parent"), hereby offers to purchase all outstanding shares (including scrip)
of Common Stock, par value $.01 per share (the "Common Shares") and all
outstanding shares of Preferred Stock, no par value per share (the "Preferred
Shares") (collectively, the Common Shares and the Preferred Shares are
referred to as the "Shares"), of PMC International, Inc., a Colorado
corporation (the "Company"), at a purchase price of $0.60 per Common Share,
net to the seller in cash, without interest thereon, and $2.50 per Preferred
Share, net to the seller in cash, without interest thereon, upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the
related Letter of Transmittal (which together constitute the "Offer").
 
  Those shareholders who tender shares will not be obligated to pay brokerage
fees or commissions or, except as set forth in the Letter of Transmittal,
transfer taxes on the purchase of Shares by the Offeror pursuant to the Offer.
The Offeror will pay all charges and expenses of Firstar Bank Milwaukee, N.A.
(f/k/a) Firstar Trust Company (the "Depositary") and Georgeson & Company Inc.
(the "Information Agent") in connection with the Offer.
 
  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER,
THE MERGER (AS HEREINAFTER DEFINED) AND THE MERGER AGREEMENT (AS HEREINAFTER
DEFINED); HAS DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR
TO AND IN THE BEST INTERESTS OF THE COMPANY'S SHAREHOLDERS; AND RECOMMENDS
THAT THE HOLDERS OF SHARES ACCEPT THE OFFER AND TENDER ALL OF THEIR SHARES IN
THE OFFER.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE HAVING BEEN VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF
COMMON SHARES AND PREFERRED SHARES WHICH, WHEN ADDED TO THE NUMBER OF COMMON
SHARES AND PREFERRED SHARES THEN OWNED BY THE PARENT AND ITS AFFILIATES,
INCLUDING ANY COMMON SHARES AND/OR PREFERRED SHARES ACQUIRED PURSUANT TO THE
CONVERSION RIGHTS OR THE OPTIONS DESCRIBED BELOW, WILL REPRESENT NOT LESS THAN
TWO-THIRDS OF THE COMMON SHARES OUTSTANDING AND TWO-THIRDS OF THE PREFERRED
SHARES OUTSTANDING, RESPECTIVELY (THE "MINIMUM CONDITION"). THE OFFER IS ALSO
SUBJECT TO OTHER TERMS AND CONDITIONS. SEE SECTION 15 OF THIS OFFER TO
PURCHASE.
 
  Value Investing Partners, Inc., the Company's financial advisor, has
delivered to the Company's Board of Directors its written opinion that, as of
October 26, 1998, the date of such opinion, the consideration to be received
by the holders of the Shares pursuant to the Offer and the Merger is fair to
such holders from a financial point of view. A copy of such opinion is
contained in the Company's Statement on Schedule 14D-9 which is also being
distributed to the Company's shareholders.
 
  The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of November 3, 1998 (the "Merger Agreement"), among the Offeror, the Parent
and the Company. The Merger Agreement provides that, among other things, as
soon as practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement, all in
accordance with the relevant provisions of the Colorado Business Corporation
Act ("CBCA"), the Offeror will be merged with and into the Company (the
"Merger"). See Section 13 herein. Following consummation of the Merger, the
Company will continue as the surviving corporation (the "Surviving
Corporation") and will be a wholly-owned subsidiary of the Parent. At the
effective time of the Merger (the "Effective Time"), each issued and
outstanding Share (other than Shares owned by the Company, the Parent, or any
subsidiary of either, including the Offeror, or Shares with respect to
 
                                       1
<PAGE>
 
which dissenters rights are properly exercised under the CBCA ("Dissenting
Shares")), will be converted into and represent the right to receive $0.60 per
Common Share (or any higher price that may be paid for each Common Share
pursuant to the Offer) in cash, without interest thereon (the "Common Share
Offer Price"), or $2.50 per Preferred Share (or any higher price that may be
paid for each Preferred Share pursuant to the Offer) in cash, without interest
thereon (the "Preferred Share Offer Price"), as appropriate. See Section 5
herein for a description of certain tax consequences of the Offer and the
Merger.
 
  The Merger Agreement provides that, promptly upon the purchase by Parent or
any of its affiliates of such number of Common Shares which, when added to the
number of Common Shares owned by Parent and the Offeror, represents at least
two-thirds of the outstanding Common Shares, and from time to time thereafter,
the Parent will be entitled to designate for election to the Board of
Directors of the Company a number of directors (rounded up to the next whole
number) that will give the Parent representation on such Board equal to the
product of (i) the total number of directors on such Board and (ii) the
percentage that the aggregate number of Common Shares owned by the Parent and
the Offeror bears to the total number of outstanding Common Shares. The
Company and its Board of Directors have agreed, upon the request by the
Parent, to promptly increase the size of the Board of Directors of the Company
and/or use its reasonable best efforts to secure the resignations of such
number of directors as is necessary to enable the Parent's designees to be
elected to the Board and to cause the Parent's designees to be so elected.
 
  The Company has advised the Offeror that as of October 22, 1998, there were
(i) 4,446,828.5 Common Shares issued and outstanding (including scrip), (ii)
138,182 Preferred Shares issued and outstanding and (iii) outstanding warrants
and options, including under the Company's stock option plans, to purchase an
aggregate of 943,290 Common Shares, all of which have exercise prices of more
than $0.60 per Common Share. Additionally, as of the date hereof, there are
(i) conversion rights granted to the Parent, pursuant to that certain
Convertible Promissory Note given by the Company, in the principal amount of
$500,000, dated October 15, 1998 (the "First Note"), to convert, at the
Parent's option, the then outstanding principal of the First Note at the time
of conversion or such lesser amount as selected by the Parent, in whole or in
part, into Preferred Shares (the "Preferred Conversion Rights"), (ii)
conversion rights granted to the Parent, pursuant to that certain Convertible
Promissory Note given by the Company, in the principal amount of $3.5 million,
dated November 3, 1998 (the "Second Note" and together with the First Note,
the "Notes") to convert, at the Parent's option the then outstanding principal
and accrued interest of the Second Note at the time of conversion or such
lesser amount as selected by the Parent, in whole or in part, into Common
Shares (the "Common Conversion Rights" and together with the Preferred
Conversion Rights, the "Conversion Rights"), (iii) an option granted to the
Parent, pursuant to that certain Stock Option Agreement between the parent and
the Company dated October 15, 1998 (the "First Stock Option Agreement"), to
purchase 111,818 Preferred Shares (the "Preferred Option") and (iv) an option
granted to the Parent, pursuant to a Stock Option Agreement dated November 3,
1998 (the "Second Stock Option Agreement" and together with the First Stock
Option Agreement collectively the "Option Agreements") to purchase 4,500,000
shares of Common Stock (the "Common Option" and together with the Preferred
Option collectively the "Options"). See Section 13. As of the date hereof,
neither the Offeror nor the Parent beneficially owns any Shares, exclusive of
the Conversion Rights and the Options. Assuming no exercise of any options and
warrants outstanding as of October 22, 1998 (which have exercise prices above
$.60 per share), and no exercise of any of the Conversion Rights and Options,
if the Offeror acquires at least 2,964,553 Common Shares and 92,122 Preferred
Shares in the Offer it will own two-thirds of the outstanding Common Shares
and Preferred Shares, respectively. Accordingly, the Minimum Condition would
be satisfied and the Offeror would have sufficient voting power to approve the
Merger without the affirmative vote of any other shareholder. The Merger
Agreement requires Parent to exercise the Conversion Rights and Options if
necessary to meet the Minimum Condition. Subsequent to October 22, 1998, the
Company purchased 150,001 outstanding warrants from the holders thereof at a
price of $0.05 per warrant. Based upon this information, and as a result of
the expiration of certain options, the purchase by the Company of the warrants
and the receipt of certain tenders pursuant to Shareholder Tender Agreements
(described below), upon full exercise of the Options and Conversion Rights,
the Offeror will not need to obtain any Common Shares or Preferred Shares in
the Offer in order to meet the Minimum Condition. In the event the Offeror
acquires at least 90% of the then outstanding Common Shares and Preferred
Shares, respectively, through the Offer or otherwise, the Offeror would be
able to effect the Merger pursuant to the short form merger provisions of the
CBCA without any action by any other holder of Shares. As of the date hereof,
thirty-one of the Company's shareholders, who beneficially own in the
aggregate 262,277
 
                                       2
<PAGE>
 
Common Shares, including all of the Company's directors and officers who own
Shares, have entered into Shareholder Tender Agreements with the Parent
whereby such shareholders have agreed to tender all of the Common Shares
beneficially owned by such shareholders pursuant to the Offer and to not
withdraw such Common Shares (the "Shareholder Tender Agreements").
 
  As a result of the Company's December 30, 1997 reverse stock split,
shareholders who would have acquired fractional shares of common stock,
instead acquired scrip. The sole rights of a holder of scrip is that upon
presentation of one share of scrip, a holder would acquire one share of common
stock.
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
1. TERMS OF THE OFFER.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), the Offeror will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 4 herein. The term "Expiration Date" means 5:00 p.m.,
Eastern time, on Thursday, December 10, 1998, unless the Offeror shall have
extended the period of time that the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as
so extended by the Offeror, shall expire.
 
  If the Offeror shall decide, in its sole discretion, to increase the
consideration offered in the Offer to holders of Common Shares and/or
Preferred Shares and if, at the time that notice of such increase is first
published, sent or given to holders of Shares in the manner specified below,
the Offer is scheduled to expire at any time earlier than the expiration of a
period ending on the tenth business day from, and including, the date that
such notice is first so published, sent or given, then the Offer will be
extended until the expiration of such period of ten business days. For
purposes of the Offer, a "business day" means any day other than a Saturday,
Sunday or a federal holiday, and consists of the time period from 12:01 a.m.
through 12:00 Midnight (Eastern Time).
 
  THE OFFER IS CONDITIONED UPON SATISFACTION OF THE MINIMUM CONDITION. THE
OFFER IS ALSO SUBJECT TO OTHER TERMS AND CONDITIONS. SEE SECTION 15 HEREIN.
The Offeror reserves the right (but shall not be obligated), in accordance
with applicable rules and regulations of the United States Securities and
Exchange Commission (the "Commission"), subject to the limitations set forth
in the Merger Agreement and described below, to waive any condition to the
Offer, provided that the Minimum Condition may be reduced or waived only with
the consent of the Company. Shares issued to the Parent upon the exercise of
the Conversion Rights and the Options may be counted toward satisfaction of
the Minimum Condition and the Merger Agreement requires Parent to exercise the
Conversion Rights and the Options if necessary to satisfy the Minimum
Condition. If the Minimum Condition or any of the other conditions set forth
in Section 15 have not been satisfied by 5:00 p.m.(Eastern Time), Thursday,
December 10, 1998 (or any other time then set as the Expiration Date), the
Offeror may, subject to the terms of the Merger Agreement as described below,
elect to (i) extend the Offer and, subject to applicable withdrawal rights,
retain all tendered Shares until the expiration of the Offer, as extended,
(ii) subject to complying with applicable rules and regulations of the
Commission, accept for payment all Shares so tendered and not extend the Offer
or (iii) terminate the Offer and not accept for payment any Shares and return
all tendered Shares to tendering shareholders. Under the terms of the Merger
Agreement, the Offeror reserves the right to waive any condition to the Offer,
to increase the price per Share payable in the Offer, and to make any other
changes in the terms and conditions of the Offer; provided, however, that the
Offeror may not change the form of consideration to be paid in the Offer,
decrease the price per Common Share or Preferred Share payable in the Offer,
reduce the maximum number of Shares to be purchased in the Offer or impose any
condition to the Offer in addition to those set forth in the Merger Agreement
or amend any other term of the Offer in a manner materially adverse to the
holders of Shares; and provided further that the Offeror may not unilaterally
waive the Minimum Condition which condition may be waived by the Offeror only
with the prior written consent of the Company. Notwithstanding the foregoing,
the Offeror may, without the consent of the Company, extend the Offer (i) if,
at the then scheduled Expiration Date of the Offer any of the conditions to
the Offer shall not have been satisfied or waived, until such conditions are
satisfied or waived, and (ii) for any period required by any rule, regulation,
interpretation or position of the Commission or the Commission staff
applicable to the Offer.
 
                                       3
<PAGE>
 
  Subject to the limitations set forth in the Merger Agreement and described
above, the Offeror reserves the right (but will not be obligated), at any time
or from time to time in its sole discretion, to extend the period during which
the Offer is open by giving oral or written notice of such extension to the
Depositary and by making a public announcement of such extension. There can be
no assurance that the Offeror will exercise its right to extend the Offer.
 
  Subject to the applicable rules and regulations of the Commission and
subject to the limitations set forth in the Merger Agreement, the Offeror also
expressly reserves the right, at any time and from time to time, in its sole
discretion, (i) to delay payment for any Shares regardless of whether such
Shares were theretofore accepted for payment, or to terminate the Offer and
not to accept for payment or pay for any Shares not theretofore accepted for
payment or paid for, upon the occurrence of any of the events described in the
conditions set forth in Section 15, by giving oral or written notice of such
delay or termination to the Depositary and (ii) at any time or from time to
time, to amend the Offer in any respect. The Offeror's right to delay payment
for any Shares or not to pay for any Shares theretofore accepted for payment
is subject to the applicable rules and regulations of the Commission,
including Rule 14e-1(c) under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), relating to the Offeror's obligation to pay for or
return tendered Shares promptly after the termination or withdrawal of the
Offer.
 
  Any extension of the period during which the Offer is open, delay in
acceptance for payment or payment, termination or amendment of the Offer will
be followed, as promptly as practicable, by public announcement thereof, such
announcement in the case of an extension to be issued not later than 9:00
a.m., Eastern time, on the next business day after the previous scheduled
Expiration Date in accordance with the public announcement requirements of
Rules 14d-4(c) and 14e-1(d) under the Exchange Act. Without limiting the
obligation of the Offeror under such rules or the manner in which the Offeror
may choose to make any public announcement, the Offeror currently intends to
make announcements by issuing a press release to the PR News Service and
making any appropriate filing with the Commission.
 
  If the Offeror makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer (including a reduction of the Minimum Condition), the Offeror will
disseminate additional tender offer materials and extend the Offer if, and to
the extent, required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange
Act or otherwise. The minimum period during which a tender offer must remain
open following material changes in the terms of the Offer or the information
concerning the Offer, other than a change in price or a change in percentage
of securities sought, will depend upon the facts and circumstances, including
the relative materiality of the terms or information changes. With respect to
a change in price or a change in percentage of securities sought, a minimum
ten business day period is generally required to allow for adequate
dissemination to shareholders and for investor response.
 
  The Company has provided the Offeror with the Company's list of shareholders
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase and the Letter of Transmittal are
being mailed to record holders of the Shares and furnished to brokers,
dealers, commercial banks, trust companies and similar persons whose names, or
the names of whose nominees, appear on the list of shareholders or, if
applicable, who are listed as participants in a clearing agency's security
position listing for subsequent transmittal to beneficial owners of Shares.
 
2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Offeror will accept for payment and will pay for all Shares
validly tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 4 promptly after the later to occur of (i) the
Expiration Date and (ii) subject to compliance with Rule 14e-1(c) under the
Exchange Act, the satisfaction or waiver of the conditions set forth in
Section 15 herein. Subject to compliance with Rule 14e-1(c) under the Exchange
Act, the Offeror expressly reserves the right to delay payment for Shares in
order to comply in whole or in part with any applicable law. See Sections 1,
16 and 18 herein. In all cases, payment for Shares accepted for payment
pursuant to the Offer will be made only after
 
                                       4
<PAGE>
 
timely receipt by the Depositary of (i) certificates for such Shares or timely
confirmation (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company (the
"Book-Entry Transfer Facilities"), pursuant to the procedures set forth in
Section 3, (ii) a properly completed and duly executed Letter of Transmittal
(or a manually signed facsimile thereof) with all required signature
guarantees or, in the case of a book-entry transfer, an Agent's Message (as

Transmittal.
 
  The term "Agent's Message" means a message transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Offeror may enforce such agreement against the participant.
 
  For purposes of the Offer, the Offeror will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not withdrawn as,
if and when the Offeror gives oral or written notice to the Depositary of the
Offeror's acceptance of such Shares for payment. In all cases, payment for
Shares purchased pursuant to the Offer will be made by deposit of the purchase
price with the Depositary, which will act as agent for tendering shareholders
for the purpose of receiving payment from the Offeror and transmitting such
payment to tendering shareholders. If, for any reason whatsoever, acceptance
for payment of any Shares tendered pursuant to the Offer is delayed, or the
Offeror is unable to accept for payment Shares tendered pursuant to the Offer,
then, without prejudice to the Offeror's rights under Section 1, the
Depositary may, nevertheless, on behalf of the Offeror, retain tendered
Shares, and such Shares may not be withdrawn except to the extent that the
tendering shareholders are entitled to withdrawal rights as described in
Section 4 below and as otherwise required by Rule 14e-1(c) under the Exchange
Act. Under no circumstances will interest be paid by the Offeror because of
any delay in making such payment.
 
  If any tendered Shares are not accepted for payment pursuant to the terms
and conditions of the Offer for any reason, or if certificates are submitted
for more Shares than are tendered, certificates for such unpurchased or
untendered Shares will be returned, without expense to the tendering
shareholder (or, in the case of Shares delivered by book-entry transfer to a
Book-Entry Transfer Facility, such Shares will be credited to an account
maintained within such Book-Entry Transfer Facility), as promptly as
practicable after the expiration, termination or withdrawal of the Offer.
 
  If, prior to the Expiration Date, the Offeror increases the price being paid
for Common Shares or Preferred Shares accepted for payment pursuant to the
Offer, such increased consideration will be paid for all Shares of such class
that are purchased pursuant to the Offer.
 
3. PROCEDURE FOR TENDERING SHARES.
 
  Valid Tenders. For Shares to be validly tendered pursuant to the Offer, a
properly completed and duly executed Letter of Transmittal (or a manually
signed facsimile thereof), with any required signature guarantees, or, in the
case of a book-entry transfer, an Agent's Message, and any other required
documents, must be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration
Date, or the tendering shareholder must comply with the guaranteed delivery
procedures set forth below. In addition, either (i) certificates representing
such Shares must be received by the Depositary or such Shares must be tendered
pursuant to the procedure for book-entry transfer set forth below, and a Book-
Entry Confirmation must be received by the Depositary, in each case prior to
the Expiration Date or (ii) the guaranteed delivery procedures set forth below
must be complied with. No alternative, conditional or contingent tenders will
be accepted. Delivery of documents to a Book-Entry Transfer Facility in
accordance with such Book-Entry Transfer Facility's procedures does not
constitute delivery to a Depositary for this Offer.
 
  Book-Entry Transfer. The Depositary will make a request to establish an
account with respect to the Shares at the Book-Entry Transfer Facility for
purposes of the Offer within two business days after the date of this Offer to
Purchase. Any financial institution that is a participant in a Book-Entry
Transfer Facility's system may make
 
                                       5
<PAGE>
 
book-entry delivery of Shares by causing a Book-Entry Transfer Facility to
transfer such Shares into the Depositary's account at a Book-Entry Transfer
Facility in accordance with such Book-Entry Transfer Facility's procedures for
transfer. Although delivery of Shares may be effected through book-entry at a
Book-Entry Transfer Facility prior to the Expiration Date, (i) the Letter of
Transmittal (or a manually signed facsimile thereof), properly completed and
duly executed, with any required signature guarantees, or an Agent's Message
in connection with a book-entry transfer, and any other required documents,
must, in any case, be transmitted to and received by the Depositary at one of
its addresses set forth on the back cover of this Offer to Purchase or (ii)
the guaranteed delivery procedures described below must be complied with.
 
  Signature Guarantee. Signatures on the Letter of Transmittal must be
guaranteed by a member in good standing of the Securities Transfer Agents
Medallion Program, or by any other bank, broker, dealer, credit union, savings
association or other entity which is an "eligible guarantor institution," as
such term is defined in Rule 17Ad-15 under the Exchange Act (each of the
foregoing being referred to as an "Eligible Institution" and, collectively, as
"Eligible Institutions"), unless the Shares tendered thereby are tendered (i)
by a registered holder of Shares who has not completed either the box labeled
"Special Delivery Instructions" or the box labeled "Special Payment
Instructions" on the Letter of Transmittal or (ii) for the account of any
Eligible Institution. If the certificates evidencing Shares are registered in
the name of a person or persons other than the signer of the Letter of
Transmittal, or if payment is to be made or delivered to, or certificates for
unpurchased Shares are to be issued or returned to, a person other than the
registered owner or owners, then the certificates for the tendered Shares must
be endorsed or accompanied by duly executed stock powers, in either case
signed exactly as the name or names of the registered owner or owners appear
on the certificates, with the signatures on the certificates or stock powers
guaranteed by an Eligible Institution as provided in the Letter of
Transmittal. See Instructions 1 and 5 of the Letter of Transmittal.
 
  Guaranteed Delivery. If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates for Shares are not immediately
available or time will not permit all required documents to reach the
Depositary prior to the Expiration Date or the procedure for book-entry
transfer cannot be completed on a timely basis, such Shares may nevertheless
be tendered if all of the following guaranteed delivery procedures are duly
complied with:
 
    (i) the tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Offeror herewith, is
  received by the Depositary, as provided below, prior to the Expiration
  Date; and
 
    (iii) the certificates for all tendered Shares, in proper form for
  transfer (or a Book-Entry Confirmation), together with a properly completed
  and duly executed Letter of Transmittal (or a manually signed facsimile
  thereof), and any required signature guarantees, or, in the case of a book-
  entry transfer, an Agent's Message, and any other documents required by the
  Letter of Transmittal are received by the Depositary within three (3)
  Nasdaq National Market trading days after the date of such Notice of
  Guaranteed Delivery.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile transmission or mail to the Depositary and must include a guarantee
by an Eligible Institution in the form set forth in the Notice of Guaranteed
Delivery.
 
  THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF DELIVERY
IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED,
IS RECOMMENDED.
 
  Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (i) certificates for such Shares or a Book-Entry
Confirmation, (ii) a properly completed and duly executed Letter of
Transmittal (or a manually signed facsimile thereof), with all required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message and (iii) any other documents required by the Letter of Transmittal.

  BACKUP FEDERAL INCOME TAX WITHHOLDING. TO PREVENT BACKUP FEDERAL INCOME TAX
WITHHOLDING WITH RESPECT TO PAYMENT OF THE PURCHASE PRICE FOR SHARES PURCHASED
PURSUANT TO THE OFFER, EACH SHAREHOLDER MUST PROVIDE THE DEPOSITARY WITH HIS
OR HER CORRECT TAX IDENTIFICATION NUMBER ("TIN") AND CERTIFY THAT HE OR SHE IS
NOT SUBJECT TO BACKUP FEDERAL WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-
9 INCLUDED IN THE LETTER OF TRANSMITTAL. SEE THE INSTRUCTIONS SET FORTH IN THE
LETTER OF TRANSMITTAL.
 
  Determination of Validity. All questions as to the form of documents and the
validity, eligibility (including timeliness and receipt) and acceptance for
payment of any tender of Shares will be determined by the Offeror, in its sole
discretion, and its determination will be final and binding on all parties.
The Offeror reserves the absolute right to reject any or all tenders of any
Shares that are determined by it not to be in proper form or the acceptance of
or payment for which may, in the opinion of the Offeror, be unlawful. The
Offeror also reserves the absolute right to waive any of the conditions of the
Offer, subject to the limitations set forth in the Merger Agreement, or any
defect or irregularity in the tender of any Shares. The Offeror's
interpretation of the terms and conditions of the Offer (including the Letter
of Transmittal and the Instructions to the Letter of Transmittal) will be
final and binding on all parties. No tender of Shares will be deemed to have
been validly made until all defects and irregularities have been cured or
waived. The Offeror, the Parent, the Information Agent, the Depositary or any
other person will not be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification.
 
  Other Requirements. By executing the Letter of Transmittal as set forth
above, a tendering shareholder irrevocably appoints designees of the Offeror
as such shareholder's proxy, with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such
shareholder's rights with respect to the Shares tendered by such shareholder
and accepted for payment by the Offeror (and any and all other Shares or other
securities or rights issued or issuable in respect of such Shares on or after
November 3, 1998). All such proxies shall be considered coupled with an
interest in the tendered Shares. This appointment is effective when, and only
to the extent that, the Offeror accepts for payment the Shares deposited with
the Depositary. Upon acceptance for payment, all prior proxies given by the
shareholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent proxies may be given or
written consent executed (and, if given or executed, will not be deemed
effective). The designees of the Offeror will, with respect to the Shares and
other securities or rights, be empowered to exercise all voting and other
rights of such shareholder as they in their sole judgment deem proper in
respect of any annual or special meeting of the Company's shareholders, or any
adjournment or postponement thereof. The Offeror reserves the right to require
that, in order for Shares to be deemed validly tendered, immediately upon the
Offeror's payment for such Shares, the Offeror must be able to exercise full
voting and other rights with respect to such Shares and the other securities
or rights issued or issuable in respect of such Shares, including voting at
any meeting of shareholders (whether annual or special and whether or not
adjourned) in respect of such Shares.
 
4. WITHDRAWAL RIGHTS.
 
  Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer
may be withdrawn at any time prior to the Expiration Date and, unless
theretofore accepted for payment pursuant to the Offer, may also be withdrawn
at any time after January 7, 1999. If the purchase of or payment for Shares is
delayed for any reason or if the Offeror is unable to purchase or pay for
Shares for any reason, then, without prejudice to the Offeror's rights under
the Offer, tendered Shares may be retained by the Depositary on behalf of the
Offeror and may not be withdrawn except to the extent that tendering
shareholders are entitled to withdrawal rights as set forth in this Section 4,
subject to Rule 14e-1(c) under the Exchange Act, which provides that no person
who makes a tender offer shall fail to pay the consideration offered or return
the securities deposited by or on behalf of security holders promptly after
the termination or withdrawal of the Offer.
 
  For a withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.
Any notice of withdrawal must specify the name of the person who tendered the
Shares to be
 
                                       7
<PAGE>
 
withdrawn, the number and class of Shares to be withdrawn and the name in
which the certificates representing such Shares are registered, if different
from that of the person who tendered the Shares. If certificates for Shares to
be withdrawn have been delivered or otherwise identified to the Depositary,
then, prior to the physical release of such certificates, the serial numbers
shown on such certificates must be submitted to the Depositary and, unless
such Shares have been tendered by an Eligible Institution, the signatures on
the notice of withdrawal must be guaranteed by an Eligible Institution. If
Shares have been tendered pursuant to the procedure for book-entry transfer
set forth in Section 3, any notice of withdrawal must also specify the name
and number of the account at the Book-Entry Transfer Facility to be credited
with the withdrawn Shares. All questions as to the form and validity
(including timeliness and receipt) of notices of withdrawal will be determined
by the Offeror, in its reasonable discretion, and its determination will be
final and binding on all parties. The Offeror, the Parent, the Depositary, the
Information Agent or any other person will not be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.
 
  Any Shares properly withdrawn will be deemed not validly tendered for
purposes of the Offer, but may be retendered at any subsequent time prior to
the Expiration Date by following any of the procedures described in Section 3
herein.
 
5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
  The following is a summary of the principal federal income tax consequences
of the Offer and the Merger to holders whose Shares are purchased pursuant to
the Offer or whose Shares are converted to the right to receive cash in the
Merger (including pursuant to the exercise of dissenters rights). The
discussion applies only to holders of Shares in whose hands Shares are capital
assets and may not apply to Shares received pursuant to the exercise of
employee stock options or otherwise as compensation, or to holders of Shares
who are in special tax situations (such as insurance companies, tax-exempt
organizations or non-U.S. persons).
 
  THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE INCLUDED FOR GENERAL
INFORMATIONAL PURPOSES ONLY AND ARE BASED UPON CURRENT LAW. BECAUSE INDIVIDUAL
CIRCUMSTANCES MAY DIFFER, EACH HOLDER OF SHARES SHOULD CONSULT SUCH HOLDER'S
OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE RULES DISCUSSED BELOW TO
SUCH SHAREHOLDER AND THE PARTICULAR TAX EFFECTS OF THE OFFER AND THE MERGER,
INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND OTHER INCOME TAX
LAWS.
 
  The receipt of cash for Shares pursuant to the Offer or the Merger
(including pursuant to the exercise of dissenters rights) will be a taxable
transaction for federal income tax purposes (and also may be a taxable
transaction under applicable state, local and other income tax laws). In
general, for federal income tax purposes, a holder of Shares will recognize
gain or loss equal to the difference between the holder's adjusted tax basis
in the Shares sold pursuant to the Offer or converted into the right to
receive cash in the Merger and the amount of cash received therefor. Gain or
loss must be determined separately for Shares acquired in different
transactions which are sold pursuant to the Offer or are converted into the
right to receive cash in the Merger, as well as for each class of Shares
involved. Such gain or loss will be capital gain or loss (other than, with
respect to the exercise of dissenters rights, amounts, if any, which are or
are deemed to be interest for federal income tax purposes, which amounts will
be taxed as ordinary income) and will be long-term gain or loss if, on the
date of sale (or, if applicable, the date of the Merger), the Shares were held
for more than one year.
 
  Payments in connection with the Offer or the Merger may be subject to
"backup withholding" at a rate of 31%. Backup withholding generally applies if
the shareholder (i) fails to furnish his or her TIN, (ii) furnishes an
incorrect TIN, (iii) fails to properly include a reportable interest or
dividend payment on his or her federal income tax return or (iv) under certain
circumstances, fails to provide a certified statement, signed under penalty of
perjury, that the TIN provided is his or her correct number and that he or she
is not subject to backup withholding. Backup withholding is not an additional
tax, but merely an advance payment, which may be refunded to the extent it
results in an overpayment of tax. Certain persons generally are entitled to
exemption from backup withholding. Certain penalties apply for failure to
furnish correct information and for failure to
 
                                       8
<PAGE>
 
include reportable payments in income. Each shareholder should consult with
his or her own tax advisor as to his or her qualification for exemption from
backup withholding and the procedure for obtaining such exemption. Tendering
shareholders may be able to prevent backup withholding by completing the
Substitute Form W-9 included in the Letter of Transmittal. See Section 3.
 
6. PRICE RANGE OF SHARES; DIVIDENDS.
 
  The Common Shares are principally traded on the OTC Bulletin Board under the
symbol "PMCI". There is no active or organized trading market for the
Preferred Shares or the scrip. The following table sets forth for the periods
indicated the high and low bid prices per Common Share as reported by the
principal market maker in the Common Shares. These prices reflect prices
between dealers, without retail markups, markdowns or commissions, and may not
necessarily represent actual transactions.

(1) Does not reflect the private placement of 1,294,250 Common Shares by the
    Company in December 1996 at $8.50 per share.
 
  On November 3, 1998, the last full day of trading prior to the announcement
of the Offer, the closing bid price per Common Share as reported by the
principal market maker in the Common Shares was $0.86 and on November 6, 1998,
the closing bid was $.60. Holders of Common Shares are urged to obtain current
market quotations for the Common Shares.
 
  The Company has not paid dividends on the Common Shares. Under the terms of
the Merger Agreement the Company is prohibited from paying any dividends on
its capital stock, including the Shares. The Company is in default in the
payment of dividends on the Preferred Shares (in the amount of $298,419 as of
March 31, 1998). The Company is prohibited by its Articles of Incorporation
from paying dividends on its Common Shares so long as it is in default in the
dividend payment of Preferred Shares.
 
7. EFFECT OF THE OFFER ON MARKET FOR COMMON SHARES, PRICE QUOTATIONS AND
  REGISTRATION UNDER THE EXCHANGE ACT.
 
  The purchase of the Shares by the Offeror pursuant to the Offer will reduce
the number of Common Shares that might otherwise trade publicly and will
reduce the number of holders of Shares, which will adversely affect the
liquidity and market value of the remaining Shares held by shareholders other
than the Offeror. Consummation of the Merger in accordance with the Merger
Agreement will eliminate all Shares held by anyone other than the Offeror and
its affiliates.
 
                                       9
<PAGE>
 
  Following consummation of the Offer, the extent of the public market for the
Common Shares and the availability of price quotations will depend upon the
number of holders of Common Shares remaining at such time, the interest in
maintaining a market in Common Shares on the part of securities firms, the
termination of registration of Common Shares under the Exchange Act, as
described below, and other factors.
 
  The Common Shares are currently registered under the Exchange Act. The
Preferred Shares are not registered under the Exchange Act and the
registration of the Common Shares may be terminated upon application by the
Company to the Commission if there are fewer than 300 record holders of Common
Shares. It is the intention of the Offeror both to consummate the Merger and
to seek to cause an application for such termination to be made as soon after
consummation of the Offer as the requirements for termination of registration
of the Common Shares are met. If such registration were terminated, the
Company would no longer legally be required to disclose publicly in proxy
materials distributed to holders of Common Shares the information which it now
must provide under the Exchange Act or to make public disclosure of financial
and other information in annual, quarterly and other reports required to be
filed with the Commission under the Exchange Act; and the officers, directors
and 10% or more shareholders of the Company would no longer be subject to the
"short-swing" insider trading reporting and profit recovery provisions of the
Exchange Act. Furthermore, if such registration were terminated, persons
holding "restricted securities" of the Company may be deprived of their
ability to dispose of such securities under Rule 144 promulgated under the
Securities Act of 1933, as amended.
 
8. CERTAIN INFORMATION CONCERNING THE COMPANY.

and other matters. The Company is required to disclose in such proxy
statements certain information, as of particular dates, concerning the

  On November 3, 1998, the Company and Parent entered into a Credit Agreement
(the "Credit Agreement") pursuant to which Parent agreed to make, through
March 31, 1999, revolving credit loans (the "Loans") to the Company in an
aggregate principal amount of up to $3,500,000 at a variable rate of interest
equal to the prime rate as published in The Wall Street Journal (Midwest
Edition). All Loans are to be evidenced by the Second Note. The proceeds of
the Loans are to be used solely to retire indebtedness under a bridge loan
provided to the Company by Dundee Bancorp, Inc. in July, 1998, to compensate
investment managers, to pay legal and investment banking fees, to make earn-
out payments under the PMCIS Acquisition Agreement, as amended, and for
general working capital and general corporate purposes, including payment of
aged payables. In connection with the Credit Agreement, the Company made
certain standard representations and warranties and agreed to certain negative
covenants, including limitations on: liens, indebtedness, investments,
payments (including dividends and distributions), the disposition of assets,
sales and leasebacks, loans, transactions with affiliates, guarantees,
formation of subsidiaries and its ability to consolidate or merge with any
other person. The Company also agreed to standard affirmative covenants,
including: timely payment of the Loans, maintenance of its corporate
existence, maintenance of licenses, timely reporting, timely payment of taxes,
inspection of properties and records, compliance with laws and other
agreements of the Company, where noncompliance with any covenant would have a
Material Adverse Effect (as defined in the Credit Agreement). Parent has the
standard remedies available to creditors in the event of any default under the
Credit Agreement including acceleration and setoff. The Loans are secured by
unlimited guarantees by three of the Company's subsidiaries (described below)
and by the assets of the Company and three of its subsidiaries (described
below).

  Except pursuant to the Conversion Rights, the Options and the Shareholder
Tender Agreements and as otherwise described in this Offer to Purchase,
neither of the Offeror, the Parent, nor, to the best knowledge of the Parent
and its subsidiaries, any of the persons listed in Schedule I to this Offer to

                                      13
<PAGE>
 
to the Offer, the aggregate purchase price and estimated fees and expenses
will be approximately $4.1 million (the aggregate purchase price and estimated
fees and expenses will be approximately $11.0 million if the Options and the
Conversion Rights are exercised in full). The Offeror will obtain all such
funds from the Parent, which currently has these funds in available cash. This
Offer is not subject to a financing condition.
 
11. BACKGROUND OF THE OFFER.
 
  During the week of September 7, 1998, Richard Glaisner, an executive officer
of one of the Parent's subsidiaries, was in Denver, Colorado on vacation and
learned from a local Denver newspaper story that the Company was seeking a
strategic investor. Mr. Glaisner, through his background and operational
responsibilities at GS/2/ Securities, Inc., a subsidiary of the Parent which
operates, in part, a business similar to that of the Company, was familiar
with the Company and its operations. On September 9, 1998, Mr. Glaisner
contacted Mr. C.R. Tucker, chief executive officer of the Company, to express
Parent's possible interest in considering an investment in the Company. On
September 10, 1998, before the Company had disclosed any confidential
information to Parent or any of its employees or affiliates, the Company and
Parent entered into a confidentiality agreement concerning information
provided as due diligence material by the Company.
 
  During the week of September 14, 1998, the Parent and the Company, through
Mr. Glaisner and Mr. Tucker, discussed various business combinations,
including a possible transaction structured as a joint venture or the sale of
substantially all of the Company's assets to the Parent, which Mr. Tucker
declined. Mr. Glaisner and Mr. Tucker then discussed a transaction whereby the
Parent would purchase a majority of the Common Stock directly from the Company
and have the right to nominate a majority of the board of directors of the
Company.
 
  In addition to Mr. Glaisner, Dennis Wallestad (Senior Vice President and
Chief Financial Officer of the Parent), and Peter Ziegler (President and Chief
Executive Officer of the Parent) discussed these arrangements with the Company
during the week of September 21, 1998.
 
  On September 25, 1998, the Parent and the Company entered into a non-binding
letter of intent to purchase a majority of the shares of Common Stock of the
Company at $.75 per share of Common Stock, with the Parent providing a
$500,000 loan to the Company to meet the Company's immediate working capital
needs.
 
  During the week of September 28, 1998, Mr. Wallestad conducted a more
detailed due diligence analysis of the Company and met with the Company's
officers in Denver, Colorado. Similarly, representatives of the Parent
forwarded a lengthy due diligence request to the Company on September 28, 1998
and Charles O'Meara (Senior Vice President and General Counsel of the Parent)
and representatives of the Parent visited the Company's headquarters and
conducted additional due diligence on October 1 and 2, 1998.
 
  On October 2, 1998, the Parent's board of directors met to consider the
possible acquisition of the Company and approved a $500,000 loan to the
Company to provide the Company with needed working capital to meet its current
obligations.
 
  On October 5, 1998, the Company executed a confidentiality agreement
covering due diligence materials provided by the Parent to the Company
pursuant to a due diligence request by the Company.
 
  During the week of October 5, 1998, the Parent discussed with Mr. Tucker,
Ms. Dobel (General Counsel of the Company), and Mr. MacKillop (President of
the Company), the terms of the First Note and revised terms of the proposed
acquisition. Specifically, the Parent proposed undertaking a tender offer for
all of the Company's Shares at $.60 per Common Share and $2.50 per Preferred
Share and entering into a $3.5 million credit facility to provide the Company
with additional working capital to meet its obligations.
 
  On October 6, 1998 and continuing through October 7, 1998, Mr. Tucker, Mr.
MacKillop and Emmett Daly, a director of the Company, met with officers of
Parent to discuss the possible terms of the proposed transaction and to
conduct due diligence on the Parent.
 
                                      14
<PAGE>
 
  On October 7, 1998, Mr. Tucker, Mr. MacKillop and Mr. Daly visited with
representatives of Parent's management at the offices of GS/2/ Securities,
Inc., a subsidiary of Parent ("GS/2/"), located in Milwaukee, Wisconsin. The
purpose of the visit was to learn more about Parent and continue negotiations
regarding the transaction. Representatives of Parent present at this meeting
included, at various times, Messrs. Ziegler, Glaisner, Wallestad, and Richard
Schilffarth, an officer of GS/2/. During those meetings, Parent informed the
Company that it was not willing to proceed under the terms of the Letter of
Intent because such items would not accomplish Parent's objectives. As a
result, the per share price and structure of the transaction were
renegotiated.
 
  During the week of October 12, 1998, the parties negotiated the terms of the
First Note and the Preferred Option and on October 15, 1998, entered into such
agreements.
 
  On October 15, 1998, the Company's board met to discuss the proposed
transaction and approved the terms of the First Note and the Preferred Option
for the Parent to purchase up to 111,818 Preferred Shares. The Preferred
Option was granted to induce Parent to purchase the First Note and to pursue
the Offer and the Merger.
 
  After October 15, members of the Company's management continued to negotiate
with members of Parent's management, especially with respect to the basis upon
which the Offer would proceed and the Merger would be consummated and with
respect to the priority of payment of certain of the Company's creditors, in
particular Dundee.
 
  On October 21, 1998, Parent's board of directors met to consider and approve
the proposed transaction, including the Merger Agreement and the $3.5 million
credit facility.
 
  On October 21 and 22, 1998, members of the Company's management met with Mr.
Glaisner and Mr. Wallestad to continue discussions about the transaction and
the Company's financial condition and operations.
 
  On October 26, 1998, the board of directors of the Company met to consider
and approve the proposed transaction. From October 26, 1998, officers of the
Company and the Parent reviewed and negotiated the final terms of the
documents, including the $3.5 million credit facility. In a joint press
release issued prior to commencement of trading on November 4, 1998, the
Parent and the Company announced, among other things, that they had entered
into the Merger Agreement and that the Parent intended to commence the Offer
within five business days following execution of the Merger Agreement. On
November 9, 1998, the Offeror commenced the Offer.
 
12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY.
 
  The purpose of the Offer, the Merger and the Merger Agreement is to enable
the Parent to acquire control of, and the entire equity interest in, the
Company. Upon consummation of the Merger, the Company will become a wholly-
owned subsidiary of the Parent. The Offer is being made pursuant to the Merger
Agreement.
 
  Under the CBCA and the Company's Articles of Incorporation, the approval of
the Board of Directors of the Company and the affirmative vote of the holders
of two-thirds of the outstanding Common Shares and Preferred Shares,
respectively, are required to approve and adopt the Merger Agreement and the
transactions contemplated thereby, including the Merger. A vote by holders of
scrip is not required to effect the Merger. The Board of Directors of the
Company has unanimously approved the Offer, the Merger and the Merger
Agreement, and, unless the Merger is consummated pursuant to the short form
merger provisions under the CBCA described below, the only remaining required
corporate action of the Company is the approval and adoption of the Merger
Agreement by the affirmative vote of the holders of at least two-thirds of the
Common Shares and Preferred Shares voting as separate classes. If the Minimum
Condition is satisfied, including satisfaction as a result of the exercise, in
whole or in part, of the Conversion Rights and/or the Options held by the
Parent, the Offeror will have sufficient voting power to cause the approval
and adoption of the Merger Agreement and the transactions contemplated thereby
without the affirmative vote of any other shareholder. See Section 13 for a
discussion of the Conversion Rights and the Options.
 
                                      15
<PAGE>
 
  In the Merger Agreement, the Company has agreed to take all action necessary
to convene a meeting of its shareholders as promptly as practicable after the
consummation of the Offer for the purpose of considering and taking action on
the Merger Agreement and the transactions contemplated thereby, if such action
is required by the CBCA. The Parent has agreed that all Shares owned by the
Parent or the Offeror (including any Shares acquired pursuant to the exercise
of the Conversion Rights of the Options) will be voted in favor of the Merger
Agreement.
 
  The Parent intends to undertake a review of the Company's operations and to
study how operations of the two companies can best be optimized. The Parent
will continue to evaluate the Company's other business and operations and will
take such actions as a result of such review as are appropriate under the
circumstances.
 
  Except as indicated in this Offer to Purchase, the Parent does not have any
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any of its subsidiaries, a sale or transfer of a
material amount of consolidated assets of the Company and its subsidiaries or
any material change in the Company's capitalization or dividend policy or any
other material changes in the Company's corporate structure or business.
 
13. THE MERGER AGREEMENT.
 
  The following summary of certain provisions of the Merger Agreement, a copy
of which has been filed as an exhibit to the Schedule 14D-1, is qualified in

  Company Actions. Pursuant to the Merger Agreement, the Company has agreed
that, subject to the fiduciary duties of the Board of Directors of the Company
under applicable law as determined by the Board of Directors of the Company in
good faith after consultation with the Company's outside counsel, it will file

accept the Offer and approve the Merger and the Merger Agreement.
 
  The Merger. The Merger Agreement provides that, upon the terms and subject
to the conditions of the Merger Agreement, and in accordance with the CBCA,
the Offeror shall be merged with and into the Company at the Effective Time.
Following the Merger, the separate corporate existence of the Offeror shall
cease and the Company shall continue as the Surviving Corporation and shall
succeed to and assume all the rights and obligations of the Offeror in
accordance with the CBCA and the Merger Agreement. The Articles of
Incorporation and the By-laws of the Company shall continue as the Articles of
Incorporation and the By-laws of the Surviving Corporation and the officers
and directors of the Offeror shall continue as the officers and directors of

  Conversion of Securities. At the Effective Time, each Common Share issued
and outstanding immediately prior thereto shall be canceled and extinguished
and each Common Share (other than Common Shares owned by the Company, the
Parent, or any affiliate of either, including the Offeror, and any Dissenting
Shares representing Common Shares) shall, by virtue of the Merger and without
any action on the part of the Offeror, the Company or the holders of the
Common Shares, be converted into and represent the right to receive an amount
equal to the Common Share Offer Price.

  Each share of common stock of the Offeror issued and outstanding immediately

validly issued and outstanding share of common stock of the Surviving

exercised dissenters rights with respect thereto in accordance with Article
113 of the CBCA will not be exchangeable for the right to receive an amount
equal to the Common Share Offer Price or Preferred Share Offer Price, as
appropriate, in cash, and instead holders of such Shares will be entitled to
receive payment of the appraised value of such stock, unless such holders fail
to perfect or withdraw or lose their right to appraisal and payment under the
CBCA, in which case Shares held by such holders will be exchangeable for the
right to receive the Common Share Offer Price or Preferred Share Offer Price,
as appropriate, in cash.

  No Solicitation. The Merger Agreement provides that neither the Company nor
any of its subsidiaries, nor any of their respective directors, officers,
employees, representatives, agents or affiliates, will directly or indirectly
encourage, solicit, initiate or, except as is required in the exercise of
fiduciary duties of the Company's directors and officers under applicable
laws, upon advice of counsel to the Company, participate in any discussions or
negotiations with, or knowingly provide any information to, any corporation,
partnership, person or other entity or group (other than the Parent or any of
its affiliates or associates) concerning any merger, sale of substantially all
the assets, sale of shares of capital stock or similar transactions involving
the Company or any material subsidiary or division of the Company, provided,
however, that nothing contained in the Merger Agreement will prohibit the
Company or its Board of Directors from (i) taking and disclosing to the
Company's shareholders a position with respect to a tender offer by a third
party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act,
(ii) making such disclosure to the Company's shareholders which, in the
judgment of the Board of Directors with the advice of counsel, may be required
under applicable law or (iii) providing information to, or participating in
discussions or negotiations with, any party that has actually made, and which
the Board of Directors believes in good faith would be capable of effecting an
acquisition of the
 
                                      18
<PAGE>
 
Company on terms that are superior, from a financial point of view, to the
Offer and the Merger if the Board of Directors in good faith believes, upon
the written advice of counsel, that the failure to so disclose would
constitute a breach of its fiduciary duty to the Company and its shareholders.
The Merger Agreement requires the Company promptly to communicate to Offeror
if it is furnishing information to or engaging in negotiations with any third
party with respect to the acquisition of the Company or any of its assets or
subsidiaries.
 
  Preservation of Relationships and Obtaining Consents. The Company has agreed
that it will, and will cause its subsidiaries to, use their reasonable best
efforts to: (i) preserve their business organizations intact; (ii) retain the
services of their present officers and key employees; (iii) preserve the
goodwill of suppliers, customers, creditors and others having business
relationships with them and (iv) obtain consents to the assignment of
contracts under the Investment Advisers Act of 1940, as amended (the
"Investment Advisers Act") required for the Consummation of the transactions
contemplated by the Merger Agreement.
 
  Warrants and Options. Warrants and options to purchase Common Shares are
outstanding under stock option plans of the Company and pursuant to grants
outside any formal plan (the "Company Stock Option Plans") and pursuant to the
Option Agreements, the Company has granted the Parent the Options to purchase
111,818 Preferred Shares at a price of $2.50 per Preferred Share and 4,500,000
Common Shares at $.60 per Common Share. See Below. Additionally, pursuant to
the First Note, the Company has granted the Parent the Preferred Conversion
Rights (providing for the conversion, at the Parent's option, of the then
outstanding principal and accrued interest of the First Note at the time of
conversion or such lesser amount as selected by the Parent, in whole or in
part, into Preferred Shares at a price of $2.50 per Preferred Share) and,
pursuant to the Second Note, the Company has granted the Parent the Common
Conversion Rights (providing for the conversion, at the Parent's Option, of
the then outstanding principal and accrued interest of the Second Note at the
time of conversion or such lesser amount as selected by the Parent, in whole
or in part, into Common Shares at a price of $0.60 per Common Share). See
below. As of the date of the Merger Agreement options for a total of 662,625
Common Shares (the "Company Stock Options") were outstanding under the Company
Stock Option Plans and warrants for a total of 118,751 Common Shares (the
"Warrants") were outstanding. The Merger Agreement provides that at the
Effective Time each Company Stock Option shall automatically terminate and be
of no further force and effect whatsoever and each Warrant shall be
automatically converted into the right to receive upon exercise thereof, in
lieu of Common Shares issuable upon exercise thereof immediately prior to the
Effective Time, the Common Share Offer Price (subject to any applicable
withholding taxes).
 
  Indemnification. The Offeror has agreed, from and after the Effective Time,
to cause the Surviving Corporation to honor the performance of certain
contracts, agreements and commitments of the Company and its subsidiaries
which indemnify certain employees and directors of the Company and its
subsidiaries. Additionally, the Offeror has agreed that for six years from the
date of the Merger Agreement the Articles of Incorporation and By-laws of the
Surviving Corporation will not be amended to reduce or limit the rights to
indemnity currently afforded thereunder.
 
  Employee Benefits. The Merger Agreement provides that if any salaried or
non-union hourly employee of the Company or any of its subsidiaries is or
becomes a participant in any written employee benefit plan or program of the
Offeror or any member of its controlled group within the meaning of the
Section 414(b) or (c) of the Code, such employee shall be credited under such
plan or program with all service prior to the Effective Time with the Company
and its subsidiaries (and any predecessor employer) to the extent credit was
given by the Company and its subsidiaries for purposes of eligibility and
vesting under such plan or program. The Parent and the Offeror have
acknowledged in the Merger Agreement that consummation of the Offer will
constitute a change of control of the Company (to the extent such concept is
relevant) for purposes of certain employment, severance or benefit agreements
and plans. See Below.
 
  Board Representation. The Merger Agreement provides that promptly upon the
purchase by Parent or any of its affiliates of such number of Common Shares
which, when added to the number of Common Shares owned by Parent and the
Offeror, represents at least two-thirds of the outstanding Common Shares, and
from time to time thereafter, the Parent shall be entitled to designate such
number of members of the Board of Directors of
 
                                      19
<PAGE>
 
the Company, rounded up to the next whole number as will give the Parent,
subject to compliance with the provisions of Section 14(f) of the Exchange
Act, representation on the Board of Directors of the Company equal to the
product of (i) the total number of directors on such Board and (ii) the
percentage that the aggregate number of Common Shares owned by the Parent and
Offeror bears to the total number of outstanding Common Shares. The Company
has agreed, upon the request of the Parent and upon the purchase of Shares
pursuant to the Offer, to promptly increase the size of the Board of Directors
of the Company and/or use its reasonable best efforts to secure the
resignations of such number of directors as is necessary to enable the
Parent's designees to be elected the Board of Directors and shall cause the
Parent's designees to be so elected. The Company has agreed to take, at its
expense, all actions required by Section 14(f) of the Exchange Act and Rule
14f-1 promulgated thereunder to effect any such election, including the
mailing to its shareholders the information required to be disclosed pursuant
thereto. The Parent will supply to the Company in writing and be solely
responsible for any information with respect to itself and its nominees,
officers, directors and affiliates required by Section 14(f) and Rule 14f-1.
 
  Conditions Precedent. The respective obligations of each party to effect the
Merger are subject to the satisfaction or waiver, at or prior to the Effective
Time, of the following conditions: (a) if required by applicable law, the
Merger Agreement and the Merger shall have been approved by the requisite vote
of the holders of two-thirds of the outstanding Common Shares and two-thirds
of the outstanding Preferred Shares voting as a separate class; (b) no
governmental entity or court of competent jurisdiction shall have enacted,
issued, promulgated, enforced or entered any law, rule, regulation, executive
order, decree or injunction which prohibits or restricts the consummation of
the Merger; and (c) the Offeror shall have accepted and paid for Shares
tendered pursuant to the Offer, including satisfaction of the Minimum
Condition (unless waived).
 
  Termination. The Merger Agreement may be terminated and the Merger
contemplated thereby may be abandoned at any time notwithstanding approval
thereof by the shareholders of the Company, but prior to the Effective Time:
(i) by mutual written consent duly authorized by the Boards of Directors of
the Company (excluding any representative of Parent or an affiliate of
Parent), the Parent and the Offeror; (ii) by either Parent or the Company if
the Effective Time shall not have occurred on or before March 31, 1999; (iii)
by either Parent or the Company if any court of competent jurisdiction in the
United States or other United States governmental body shall have issued an
order, decree or ruling, or taken any other action restraining, enjoining, or
otherwise prohibiting the Merger and such order, decree, ruling or other
action has become final and non-appealable; (iv) by the Offeror, if (a) due to
an occurrence or circumstance that would result in a failure to satisfy any of
the conditions set forth in Section 15 of this Offer to Purchase, the Offeror
shall have (1) failed to commence the offer within 20 days following the date
of the Merger Agreement, (2) terminated the Offer or the Offer shall have
expired without the purchase of the Shares thereunder at any time after the
latest date, if any, to which the Offer shall have been extended pursuant to
the Merger Agreement or (3) failed to pay for Shares pursuant to the Offer by
the 40th business day following such commencement, unless such failure to
commence, termination or failure to pay for Shares shall have been caused by
or resulted from the failure of the Offeror or an affiliate to perform in any
material respect its material covenants and agreements contained in the Merger
Agreement; or (b) prior to the purchase of Shares pursuant to the Offer, the
Board of Directors of the Company shall have withdrawn or modified in a manner
adverse to the Offeror its approval or recommendation of the Offer, the Merger
Agreement or the Merger, or shall have recommended another Offer, or shall
have resolved to do any of the foregoing; provided, however, that the Offeror
shall have no right to terminate the Merger Agreement and abandon the Merger
if the Company withdraws or modifies its recommendation of the Offer, the
Merger Agreement, or the Merger, by reason of taking and disclosing to the
Company's shareholders a position contemplated by Rule 14e-2(a)(2) or (3)
promulgated under the Exchange Act with respect to another proposal, and if
within ten days of taking and disclosing to its shareholders the
aforementioned position, the Company publicly reconfirms its recommendation of
the Offer, the Merger Agreement and the Merger and takes and discloses to the
Company's shareholders a recommendation to reject such other proposal as
contemplated by Rule 14e-2(a)(1) promulgated under the Exchange Act; or (v) by
the Company, if (a) due to an occurrence or circumstance that would result in
a failure to satisfy any of the conditions set forth in Section 15 of this
Offer to Purchase or otherwise, the Offeror shall have (1) failed to commence
the Offer as provided in the Merger Agreement within 20 days following the
date of the Merger Agreement, (2) terminated the Offer or the Offer shall have
expired without the purchase of Shares thereunder at any time after the latest
date, if any, to which
 
                                      20
<PAGE>
 
the Offer shall have been extended in accordance with the terms of the Merger
Agreement or (3) failed to pay for Shares pursuant to the Offer by the 40th
business day following such commencement, unless such failure to commence,
termination or failure to pay for Shares shall have been caused by or resulted
from the occurrence or existence of the condition described in paragraph (iv)
or (vii) of Section 15 of this Offer to Purchase or (b) prior to the purchase
of Shares pursuant to the Offer, (1) a corporation, partnership, person or
other entity or group shall have made a bona fide proposal that the Board of
Directors of the Company believes, in good faith, after consultation with its
legal and financial advisors, is more favorable to the Company and its
shareholders than the Offer and the Merger and (2) the Offeror does not make,
within ten days of the Offeror receiving notice of such third party proposal,
an offer which the Board of Directors believes, in good faith after
consultation with its legal and financial advisors, is at least as favorable
to the Company's shareholders as such third party proposal.
 
  Fees and Expenses. The Company has agreed in the Merger Agreement to pay the
Offeror the sum of $250,000 and all actual, documented out-of-pocket expenses
relating to the Offer and the Merger in an amount up to $100,000 if the Merger
Agreement or the transactions contemplated thereby are terminated or abandoned
(unless at such time the Parent or the Offeror shall be in breach in any
material respect of any of its obligations or representations and warranties
thereunder) and prior to or contemporaneously with such termination or
abandonment, any corporation, partnership, person, other entity or group (as
defined in Section 13(d)(3) of the Exchange Act) other than Parent or any of
its subsidiaries or affiliates, shall have acquired or beneficially owns (and
failed to tender such shares) (as defined in Rule 13d-3 promulgated under the
Exchange Act) at least 33.34% of the then outstanding Common Shares.
 
  Except as provided in the preceding paragraph, the Merger Agreement provides
that whether or not the Merger is consummated, each party thereto shall pay
its own expenses incident to preparing for, entering into and carrying out the
Merger Agreement and the consummation of the Offer and the Merger.
 
  Employment Agreement. Mr. Scott MacKillop, the President of the Company, was
a party to a two-year employment agreement dated September 23, 1997, with PMC
Investment Services, Inc. ("PMCIS"), a wholly owned subsidiary of the Company,
formerly known as ADAM Investment Services, Inc. PMCIS had the right to
terminate the agreement at any time after the one-year anniversary of the date
of the agreement by giving six months' prior written notice. The agreement
provided for a minimum salary of $240,000, an annual bonus of up to $50,000,
options to acquire 62,500 shares of Common Stock at an exercise price of
$6.485 per share (with such options expiring six years from the date of grant
and vesting ratably 20% per year over a five-year period beginning September
24, 1998), and participation in the Company's other benefit plans. As a
condition to Parent's agreeing to participate in the Offer and the Merger, Mr.
MacKillop agreed to terminate this agreement and to enter into an employment
agreement with the Company, as described below.
 
  On November 3, 1998, Mr. MacKillop and the Company entered into a one-year
employment agreement. This agreement provides for a minimum salary of $240,000
that the Company may augment with performance-based increases as established
in the Company's discretion, and participation in the Company's other benefit
plans. In addition, the new employment agreement provides that if payment in
full of the 1998 earn-out payment due under the PMCIS Acquisition Agreement is
not paid in accordance with the PMCIS Acquisition Agreement, as amended, then
the Company will pay Mr. MacKillop $250,000 on the earlier of April 2, 1999 or
two business days after the consummation of the Merger. Upon the effectiveness
of this agreement, Mr. MacKillop's existing employment agreement with PMCIS
(as described above) was terminated.
 
  Change in Control Severance Agreements. In May 1998, the Company entered
into Change in Control Severance Agreements with Mr. MacKillop, Stephen A. Ash
and Maureen E. Dobel (for purposes of their respective agreements, each the
"Executive"). Each of these agreements provides that if a Change in Control
(as defined in each such agreement) occurs, and before the two-year
anniversary of the Change in Control or the Executive's 65th birthday,
whichever comes first, (i) the Executive's employment is terminated by the
Company or any of its subsidiaries (unless such termination is for cause or
because Executive becomes permanently disabled and begins to receive
disability benefits pursuant to the long-term disability plan in effect for,
or applicable to, the Executive immediately prior to the Change in Control),
or (ii) if the Executive terminates his
 
                                      21
<PAGE>
 
or her employment with the Company or any of its subsidiaries for Good Reason
(as defined in each such agreement), then Executive will be entitled to (x) a
cash payment payable during each month of the Continuation Period (twenty-
seven months following termination of employment for Messrs. MacKillop and
Ash, and twelve months following termination of employment for Ms. Dobel) in
an amount equal to 1/12 of the sum of the Executive's annual base salary and
the average of the Executive's annual bonus over the preceding three fiscal
years, (y) a lump-sum cash payment which the Company will pay within ten
business days after the expiration of the Continuation Period equal to the
Company matching contributions that would have been made under the Company's
401(k) savings plan(s) on the amounts described in the preceding clause (x) if
the Executive had continued in employment and participated to the fullest
extent under such plan(s), and (z) during the Continuation Period, the Company
will arrange to provide the Executive with continued medical, group life, and
dental benefits substantially similar, and subject to the same employee
contribution requirement, to those that the Executive was receiving or
entitled to receive immediately prior to the date his or her employment is
terminated.
 
  In addition to the foregoing general terms, Mr. MacKillop's Change in
Control Severance Agreement also provides that if a Change in Control occurs,
then Mr. MacKillop may terminate his employment with the Company or any of its
subsidiaries for any reason, or without reason, during the sixty-day period
immediately following the first anniversary of a Change in Control giving rise
to a right to severance compensation. Pursuant to the employment agreement
entered into as of November 3, 1998 between the Company and Mr. MacKillop, Mr.
MacKillop's Change in Control Severance Agreement was terminated.
 
  Conversion Rights and Option. Pursuant to the First Note, the Company has
granted the Parent Preferred Conversion Rights to convert the then outstanding
principal of the First Note at the time of conversion or such lesser amount as
selected by the Parent, in whole or in part, into Preferred Shares at a price
per Preferred Share of $2.50. Pursuant to the Second Note, the Company has
granted the Parent Common Conversion Rights to convert the then outstanding
principal and accrued interest of the Second Note of the time of conversion or
such lesser amount as selected by the Parent, in whole or in part, into Common
Shares, at a price per Common Share of $0.60. In addition, pursuant to the
Option Agreements, the Company has granted the Parent Options to purchase
111,818 Preferred Shares at a price per Preferred Share of $2.50 and 4,500,000
Common Shares at a price per Common Share of $0.60. The Conversion Rights and
the Options are intended to ensure the likelihood that the Offer and Merger
will be consummated in accordance with the terms of the Merger Agreement.
Consequently, certain aspects of the Conversion Rights and the Options may
have the effect of discouraging persons who might now, or prior to the
Effective Time may, be interested in acquiring all or a significant interest
in, other otherwise effecting a business combination with the Company or from
considering or proposing such a transaction, even if such persons were
prepared to offer to pay consideration which had a higher value than $0.60 per
Common Share or $2.50 per Preferred Share. The Conversion Rights and the
Options may be exercised, in whole or in part, at any time. The Conversion
Rights will terminate upon the earlier of (i) the Effective Time or (ii)
payment by the Company of the entire unpaid principal and accrued interest
under the Notes, the Preferred Option will terminate on December 31, 1999 and
the Common Option will terminate on the later of March 31, 1999 or fifteen
days after the date all loans and interest from Parent and its affiliates to
the Company have been repaid in full and all amounts due to Parent under the
Merger Agreement have been paid in full. The Purchaser has agreed to exercise
the Conversion Rights and/or the Options in order to meet the Minimum
Condition.
 
  Shareholder Tender Agreements. As of the date hereof, thirty-one of the
Company's shareholders who beneficially own in the aggregate 262,277 Common
Shares, including all of the Company's officers and directors who own Shares,
have entered into Shareholder Tender Agreements with the Parent whereby the
shareholders have agreed to tender all of the Common Shares beneficially owned
by such shareholders pursuant to the Offer and not withdraw such shares. If
any of the conditions of the Offer as set forth herein have not been satisfied
by December 31, 1998, the Shareholder Tender Agreements will terminate and the
Parent will return all Shares tendered pursuant to such agreements.
 
14. DIVIDENDS AND DISTRIBUTIONS.
 
  The Merger Agreement provides that neither the Company nor any of its
subsidiaries will, among other things, prior to the Effective Time (i) declare
or pay any dividend (whether in cash, stock or property) or make
 
                                      22
<PAGE>
 
any other distribution with respect to any shares of its capital stock, (ii)
split, combine or reclassify any of its capital stock or issue or authorize
the issuance of any other securities in respect of, in lieu of or in
substitution for shares of its capital stock or (iii) repurchase or otherwise
acquire any shares of capital stock of the Company; or (iv) issue, deliver or
sell or authorize or propose the issuance, delivery or sale of, any shares of
its capital stock or any class of securities convertible into, or
subscriptions, rights, warrants or options to acquire, or enter into other
agreements or commitments of any character obligating it to issue any such
shares or other convertible securities other than the issuance of Shares
pursuant to the exercise of the Conversion Rights, the Options, the Company
Stock Options or the Warrants.
 
15. CERTAIN CONDITIONS TO OFFEROR'S OBLIGATIONS.
 
  Notwithstanding any other term of the Offer or of the Merger Agreement, the
Offeror is not required to accept for payment, purchase or pay for, subject to

postpone the acceptance for payment of and payment for shares if (i) on or

  worsening thereof; or
 
    (ii) there shall have been any statute, rule or regulation enacted,
  promulgated, entered or enforced or deemed applicable, or any decree, order

  consummation of the Merger, (b) prohibits or restricts the ownership or
  operation by the Offeror (or any of its affiliates or subsidiaries) of any
  portion of its or the Company's business or assets which is material to the

  however, that the Offeror and the Parent shall have used their best efforts
  to have any such decree, order or injunction vacated or reversed,
  including, without limitation, by proffering their willingness to accept an
  order embodying any arrangement required to be made by the Offeror or the
  Parent pursuant to the Merger Agreement (and notwithstanding anything in
  this subsection (ii) to the contrary, no terms, conditions or provisions of
  an order embodying such an arrangement shall constitute a basis for the
  Offeror asserting nonfulfillment of the conditions contained in this
  subsection (ii)); or
 
    (iii) the Merger Agreement shall have been terminated in accordance with
  its terms; or
 
    (iv) the Company shall have breached or failed to perform any of its
  covenants or agreements which breach or failure to perform is material to
  the obligations of the Company under the Merger Agreement taken as a whole
  or any of the representations and warranties of the Company set forth in
  the Merger Agreement shall not have been true in any respect which is
  material to the Company and its subsidiaries taken as a whole, in each
  case, when made or a material adverse change in the financial condition or
  results of operations of the Company and its subsidiaries taken as a whole,
  provided that the aggregate effect under this condition shall be in excess
  of $250,000; or
 
                                      23
<PAGE>
 
    (v) the Board of Directors of the Company shall have publicly withdrawn
  or modified in any material respect adverse to the Offeror its
  recommendation of the Offer; provided, however, the Offeror shall have no
  right to terminate the Offer or not accept for payment or pay for any
  Shares if the Company withdraws or modifies its recommendation of the Offer
  and the Merger, by reason of taking and disclosing to the Company's
  shareholders a position contemplated by Rule 14e-2(a)(2) or (3) promulgated
  under the Exchange Act with respect to another proposal, and if within ten
  days of taking and disclosing to its shareholders the aforementioned
  position, the Company publicly reconfirms its recommendation of the Offer
  and Merger and takes and discloses to the Company's shareholders a
  recommendation to reject such other proposal as contemplated by Rule 14e-

    (vi) Parent and the Company shall have agreed that the Offeror shall

  The foregoing conditions are for the sole benefit of the Parent and the
Offeror and may be asserted by the Parent regardless of the circumstances
giving rise to any such condition and may be waived by the Parent, in whole or
in part, at any time and from time to time, in the reasonable discretion of
the Parent. The failure by the Parent or the Offeror at any time to exercise
any of the foregoing rights will not be deemed a waiver of any right, the
waiver of such right with respect to any particular facts or circumstances
shall not be deemed a waiver with respect to any other facts or circumstances,
and each right will be deemed an ongoing right which may be asserted at any
time and from time to time.
 
  Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not theretofore accepted for payment shall forthwith be
returned by the Depositary to the tendering shareholders.
 
16. CERTAIN REGULATORY AND LEGAL MATTERS.
 
  Except as set forth in this Section, the Offeror is not aware of any
approval or other action by any governmental or administrative agency which
would be required for the acquisition or ownership of Shares by the Offeror as
contemplated herein. Should any such approval or other action be required, it
will be sought, but the Offeror has no current intention to delay the purchase
of Shares tendered pursuant to the Offer pending the outcome of any such
matter, subject, however, to the Offeror's right to decline to purchase Shares
if any of the conditions specified in Section 15 shall have occurred. There
can be no assurance that any such approval or other action, if needed, would
be obtained or would be obtained without substantial conditions, or that
adverse consequences might not result to the Company's business or that
certain parts of the Company's business might not have to be disposed of if
any such approvals were not obtained or other action taken.
 
  State Takeover Laws. A number of states have adopted laws and regulations
applicable to attempts to acquire securities of corporations which are
incorporated, or have substantial assets, shareholders, principal executive
offices or principal places of business, or whose business operations
otherwise have substantial economic effects in such states. In Edgar v. MITE
Corp., in 1982, the Supreme Court of the United States (the "U.S. Supreme
Court") invalidated on constitutional grounds the Illinois Business Takeover
statute, which, as a matter of state securities law, made takeovers of
corporations meeting certain requirements more difficult. However, in 1987, in
CTS Corp. v. Dynamics Corp. of America, the U.S. Supreme Court held that the
State of Indiana could, as a matter of corporate law and, in particular, with
respect to those aspects of corporate law concerning corporate governance,
constitutionally disqualify a potential acquirer from voting on the affairs of
a target corporation without the prior approval of the remaining shareholders.
The state law before the U.S. Supreme Court was by its terms applicable only
to corporations that had a substantial number of shareholders in the state and
were incorporated there.
 
  While Colorado, the Company's state of incorporation, has not adopted any
such takeover laws or regulations, the Company, directly or through
subsidiaries, conducts business in certain states of the United

States which have enacted takeover laws. The Offeror does not know whether any
of these laws will, by their terms, apply to the Offer or the Merger and has
not complied with any such laws. Should any person seek to apply any state
takeover law, the Offeror will take such action as then appears desirable,
which may include challenging the validity or applicability of any such
statute in appropriate court proceedings. In the event it is asserted that one
or more state takeover laws is applicable to the Offer or the Merger, and an
appropriate court does not determine that it is inapplicable or invalid as
applied to the Offer, the Offeror might be required to file certain
information with, or receive approvals from, the relevant state authorities.
In addition, if enjoined, the Offeror might be unable to accept for payment
any Shares tendered pursuant to the Offer, or be delayed in continuing or
consummating the Offer and the Merger. In such case, the Offeror may not be
obligated to accept for payment any Shares tendered. See Sections 15 and 18
herein.
 
17. FEES AND EXPENSES.
 
  Neither the Offeror nor the Parent, nor any officer, director, stockholder,
agent or other representative of the Offeror or the Parent, will pay any fees
or commissions to any broker, dealer or other person for soliciting tenders of
Shares pursuant to the Offer. Brokers, dealers, commercial banks and trust
companies and other nominees will, upon request, be reimbursed by the Offeror
for customary mailing and handling expenses incurred by them in forwarding
materials to their customers.
 
  The Offeror has retained Firstar Bank Milwaukee, N.A. as Depositary and
Georgeson & Company Inc. as Information Agent in connection with the Offer.
The Information Agent and the Depositary will receive reasonable and customary
compensation for their services in connection with the Offer and the Merger
and reimbursement for their reasonable out-of-pocket expenses. The Depositary
will also be indemnified by the Offeror against certain liabilities in
connection with the Offer and the Merger.
 
18. MISCELLANEOUS.
 
  The Offer is not being made to, nor will tenders be accepted from or on
behalf of, holders of Shares residing in any jurisdiction in which the making
or acceptance thereof would not be in compliance with the securities, blue sky
or other laws of such jurisdiction. In any jurisdiction where the securities,
blue sky or other laws require the Offer to be made by a licensed broker or
dealer, the Offer shall be deemed to be made on behalf of the Offeror by one
or more registered brokers or dealers licensed under the laws of such
jurisdiction.
 
  No person has been authorized to give any information or make any
representation on behalf of the Offeror other than as contained in this Offer
to Purchase or in the Letter of Transmittal, and, if any such information or
representation is given or made, it should not be relied upon as having been
authorized by the Offeror.
 
  The Offeror and the Parent have filed with the Commission the Schedule 14D-
1, pursuant to Section 14(d)(1) of the Exchange Act and Rule 14d-1 promulgated
thereunder, furnishing certain information with respect to the Offer. Such
Schedule 14D-1 and any amendments thereto, including exhibits, may be examined
and copies may be obtained at the same places and in the same manner as set
forth with respect to the Company in Section 8 (except that exhibits will not
be available at the regional offices of the Commission).

and attorney-in-fact of the undersigned (with full knowledge that said
Depositary also acts as the agent of the Purchaser) with respect to such
Shares with full power of substitution (such power of attorney being deemed to

    (a) deliver certificate(s) for such Shares or transfer ownership of such
  Shares on the account books maintained by the Book-Entry Transfer Facility,

  The undersigned hereby represents and warrants to the Purchaser that:
 
    (a) the undersigned understands that tenders of Shares pursuant to any
  one of the procedures described in Section 3 of the Offer to Purchase and
  in the instructions hereto will constitute the undersigned's acceptance of
  the terms and conditions of the Offer, including the undersigned's
  representation and warranty that:
 
      (i) the undersigned has a net long position in Shares or equivalent
    securities at least equal to the Shares tendered within the meaning of
    Rule 14e-4 under the Securities Exchange Act of 1934, as amended (the
    "1934 Act"), and
 
      (ii) such tender of Shares complies with Rule 14e-4 under the 1934
    Act;
 
    (b) when and to the extent the Purchaser accepts such Shares for

  their sale or transfer, and not subject to any adverse claim;
 
    (c) on request, the undersigned will execute and deliver any additional
  documents the Depositary or the Purchaser deems necessary or desirable to

Transmittal shall survive the death or incapacity of the undersigned, and any
obligation of the undersigned hereunder shall be binding upon the heirs,
personal representatives, executors, administrators, successors, assigns,
trustees in bankruptcy, and legal representatives of the undersigned. Except
as stated in the Offer to Purchase, this tender is irrevocable.
 
  The name(s) and address(es) of the registered holder(s) should be printed
above, if they are not already printed above, exactly as they appear on the
certificates representing Shares tendered hereby. The type (common or
preferred) and certificate numbers, the number of Shares represented by such
certificates and the number of Shares that the undersigned wishes to tender,
should be set forth in the appropriate boxes above.
 
  The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase, the Purchaser may terminate or amend the Offer or may
postpone the acceptance for payment of, or the payment for, Shares tendered or

Shares tendered hereby. In any such event, the undersigned understands that
certificate(s) for any Shares delivered herewith but not tendered or not
purchased will be returned to the undersigned at the address indicated above,
unless otherwise indicated under the "Special Payment Instructions" or
"Special Delivery Instructions" boxes below. The undersigned recognizes that
the Purchaser has no obligation, pursuant to the Special Payment Instructions,
to transfer any certificate for Shares from the name of its registered holder,
or to order the registration or transfer of Shares tendered by book-entry
transfer, if the Purchaser purchases none of the Shares represented by such
certificate or tendered by such book-entry transfer.
 
  The undersigned understands that acceptance of Shares by the Purchaser for
payment will constitute a binding agreement between the undersigned and the
Purchaser upon the terms and subject to the conditions of the Offer.

                                 INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
  1. GUARANTEE OF SIGNATURES. No signature guarantee is required if:
 
    (a) this Letter of Transmittal is signed by the registered holder of the
  Shares (which term, for purposes of this document, shall include any
  participant in a Book-Entry Transfer Facility's system whose name appears
  on a security position listing as the owner of such Shares) exactly as the
  name of the registered holder appears on the certificate(s) tendered with
  this Letter of Transmittal and such registered holder(s) has completed
  neither the box entitled "Special Payment Instructions" nor the box
  entitled "Special Delivery Instructions" above; or
 
    (b) such Shares are tendered for the account of a participant in the
  Security Transfer Agent's Medallion Program, the New York Stock Exchange
  Medallion Signature Guarantee Program, or the Stock Exchange Medallion
  Program (each such entity, an "Eligible Institution").
 
  In all other cases, an Eligible Institution must guarantee all signatures on
this Letter of Transmittal. See Instruction 5.
 
  2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES. This Letter of Transmittal is to be used only if certificates for
Shares are delivered with it to the Depositary (or such certificates will be
delivered pursuant to a Notice of Guaranteed Delivery previously sent to the
Depositary) or if a tender for Shares is being made concurrently pursuant to
the procedure for tender by book-entry transfer set forth in Section 3 of the
Offer to Purchase. Certificates for all physically tendered Shares or
confirmation of a book-entry transfer into the Depositary's account at a Book-
Entry Transfer Facility of Shares tendered electronically, together in each
case with a properly completed and duly executed Letter of Transmittal or duly
executed and manually signed facsimile of it, and any other documents required
by this Letter of Transmittal, should be mailed or delivered to the Depositary
at the appropriate address set forth herein and must be delivered to the
Depositary on or before the Expiration Date (as defined in the Order of
Purchase). DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  Shareholders whose certificates are not immediately available or who cannot
deliver certificates for their Shares and all other required documents to the
Depositary before the Expiration Date, or whose Shares cannot be delivered on
a timely basis pursuant to the procedures for book-entry transfer, must, in
any case, tender their Shares by or through any Eligible Institution by
properly completing and duly executing and delivering a Notice of Guaranteed
Delivery (or facsimile of it) and by otherwise complying with the guaranteed
delivery procedure set forth in Section 3 of the Offer to Purchase. Pursuant
to such procedure, certificates for all physically tendered Shares or book-
entry confirmations, as the case may be, as well as a properly completed and
duly executed Letter of Transmittal (or facsimile of it) and all other
documents required by this Letter of Transmittal, must be received by the
Depositary within the time period provided in Section 3 of the Offer to
Purchase.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mail to the Depositary and must include a
signature guarantee by an Eligible Institution in the form set forth in such
Notice. For Shares to be tendered validly pursuant to the guaranteed delivery
procedure, the Depositary must receive the Notice of Guaranteed Delivery on or
before the Expiration Date.
 
  THE METHOD OF DELIVERY OF ALL DOCUMENTS, INCLUDING CERTIFICATES FOR SHARES,
IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
DELIVERY.
 
  The Purchaser will not accept any alternative, conditional or contingent
tenders, nor will it purchase any fractional Shares, except as expressly
provided in the Offer of Purchase. All tendering shareholders, by execution of
this Letter of Transmittal (or a facsimile of it), waive any right to receive
any notice of the acceptance of their tender.
<PAGE>
 
  3. INADEQUATE SPACE. If the space provided in the box captioned "Description
of Shares Tendered" is inadequate, the certificate numbers, the class or
classes, and/or the number of Shares should be listed on a separate signed
schedule and attached to this Letter of Transmittal.
 
  4. PARTIAL TENDERS AND UNPURCHASED SHARES. (Not applicable to shareholders
who tender by book entry transfer.) If fewer than all of the Shares evidenced
by any certificate are to be tendered, fill in the number of Shares that are
to be tendered in the column entitled "Number of Shares Tendered," in the box
captioned "Description of Shares Tendered." In such case, if any tendered
Shares are purchased, a new certificate for the remainder of the Shares
(including any Shares not purchased) evidenced by the old certificate(s) will
be issued and sent to the registered holder(s), unless otherwise specified in
either the "Special Payment Instructions" or "Special Delivery Instructions"
box on this Letter of Transmittal, as soon as practicable after the Expiration
Date. Unless otherwise indicated, all Shares represented by the
certificates(s) listed and delivered to the Depositary will be deemed to have
been tendered.
 
  5. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.
 
    (a) If this Letter of Transmittal is signed by the registered holder(s)
  of the Shares tendered hereby, the signature(s) must correspond exactly
  with the name(s) as written on the face of the certificate(s) without any
  change whatsoever.
 
    (b) If any tendered Shares are registered in the names of two or more
  joint holders, each such holder must sign this Letter of Transmittal.
 
    (c) When this Letter of Transmittal is signed by the registered holder(s)
  of the Shares listed and transmitted hereby, no endorsement(s) of
  certificate(s) representing such Shares or separate stock power(s) are
  required unless payment is to be made, or the certificate(s) for the Shares
  not tendered or not purchased are to be issued, to a person other than the
  registered holder(s). If this Letter of Transmittal is signed by a person
  other than the registered holder(s) of the certificate(s) listed, or if
  payment is to be made to a person other than the registered holder(s), the
  certificate(s) must be endorsed or accompanied by appropriate stock
  power(s), in either case signed exactly as the name(s) of the registered
  holder(s) appear(s) on the certificate(s). SIGNATURE(S) ON SUCH
  CERTIFICATE(S) OR STOCK POWER(S) MUST BE GUARANTEED BY AN ELIGIBLE
  INSTITUTION. See Instruction 1.
 
    (d) If this Letter of Transmittal or any certificate(s) or stock
  powers(s) are signed by trustees, executors, administrators, guardians,
  attorneys-in-fact, officers of corporations or others acting in fiduciary
  or representative capacity, such persons should so indicate when signing
  and must submit proper evidence satisfactory to the Purchaser of their
  authority to so act.
 
  6. STOCK TRANSFER TAXES. Except as provided in this Instruction 6, no stock
transfer tax stamps or funds to cover such stamps need accompany this Letter
of Transmittal. The Purchaser will pay or cause to be paid any stock transfer
taxes payable on the transfer to it of Shares purchased pursuant to the Offer.
If, however:
 
    (a) payment of the aggregate Purchase Price for Shares tendered hereby
  and accepted for purchase is to be made to any other person than the
  registered holder(s);
 
    (b) Shares not tendered or not accepted for purchase are to be registered
  in the name(s) of any person(s) other than the registered holder(s); or
 
    (c) tendered certificates are registered in the name(s) of any person(s)
  other than the person(s) signing this Letter of Transmittal;
 
then the Depositary will deduct from such aggregate purchase price the amount
of any stock transfer taxes (whether imposed on the registered holder, such
other person or otherwise) payable on account of the transfer to such person,
unless satisfactory evidence of the payment of such taxes or any exemption
from them is submitted.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If certificate(s) for Shares
not tendered or not purchased and/or check(s) are to be issued in the name of
a person other than the signer of the Letter of Transmittal or to the signer
at a different address, the boxes captioned "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed as applicable and signatures must be guaranteed as described in
Instruction 1.
<PAGE>
 
  8. IRREGULARITIES. All questions as to the number of Shares to be accepted,
the price to be paid therefor and the validity, form, eligibility (including
time of receipt) and acceptance for payment of any tender of Shares will be
determined by the Purchaser in its sole discretion, which determinations shall
be final and binding on all parties. The Purchaser reserves the absolute right
to reject any or all tenders of Shares it determines not to be in proper form
or the acceptance of which or payment for which may, in the opinion of the
Purchaser's counsel, be unlawful. The Purchaser also reserves the absolute
right to waive any of the conditions of the Offer and any defect or
irregularity in the tender of any particular Shares, and the Purchaser's
interpretation of the terms of the Offer (including these instructions) will
be final and binding on all parties. No tender of Shares will be deemed to be
properly made until all defects and irregularities have been cured or waived.
Unless waived, any defects or irregularities in connection with tenders must
be cured within such time as the Purchaser shall determine. Neither the
Purchaser, Depositary, nor any other person is or will be obligated to give
notice of any defects or irregularities in tenders and none of them will incur
any liability for failure to give any such notice.
 
  9. QUESTIONS AND REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions
and requests for assistance may be directed to, or additional copies of the
Offer to Purchase, the Notice of Guaranteed Delivery and this Letter of
Transmittal may be obtained from, the Information Agent at its address and
telephone number set forth at the end of this Letter of Transmittal or from
your broker, dealer, commercial bank or trust company.
 
  10. 31% BACKUP WITHHOLDING. Under Federal income tax law, a shareholder who
receives a payment pursuant to the Offer is required to provide the Depositary
(as payor) with such shareholder's correct taxpayer identification number
("TIN") on Substitute Form W-9 below. If the shareholder is an individual, the
TIN is his or her social security number. If the Depositary is not provided
with the correct TIN, payments that are made to such shareholder or other
payee with respect to the Offer may be subject to 31% backup withholding.
 
  Certain shareholders (including, among others, certain foreign individuals)
may not be subject to these backup withholding and reporting requirements. In
order for a foreign individual to qualify as an exempt recipient, the
shareholder must submit a Form W-8, signed under penalties of perjury,
attesting to that individual's exempt status. A Form W-8 can be obtained from
the Depositary. See the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for more instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the shareholder or other payee. Backup withholding
is not an additional tax. Rather, the tax liability of persons subject to
backup withholding will be reduced by the amount of tax withheld, provided
that the required information is given to the Internal Revenue Service. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.
 
  The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
shareholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in part 3 is checked, the
shareholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN
is provided to the Depositary. However, such amounts will be refunded to such
shareholder if a TIN is provided to the Depositary within 60 days.
 
  The shareholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional guidance on which number to report.
 
  11. WITHHOLDING FOR NON-U.S. SHAREHOLDERS. Although a non-U.S. shareholder
may be exempt from U.S. Federal backup withholding, certain payments to non-
U.S. shareholders are subject to U.S. withholding tax at a rate of 30%. The
Depositary will withhold the 30% from gross payments made to non-U.S.
shareholders pursuant to the Offer unless the Depositary determines that a
non-U.S. shareholder is either exempt from the withholding or entitled to a
reduced withholding
<PAGE>
 
rate under an income tax treaty. For purposes of this discussion, a "non-U.S.
shareholder" means a shareholder who is not (i) a citizen or resident of the
United States, (ii) a corporation or partnership created or organized in the
United States or under the law of the United States or of any State or
political subdivision of the foregoing, (iii) an estate the income of which is
includible in gross income for U.S. federal income tax purposes regardless of
its source, or (iv) a "United States Trust." A United States Trust is any
trust if, and only if, (i) a court within the United States is able to
exercise primary supervision over the administration of the trust and (ii) one
or more U.S. trustees have the authority to control all substantial decisions
of the trust. A non-U.S. shareholder will not be subject to the withholding
tax if the payment from the Company is effectively connected with the conduct
of a trade or business in the United States by such non-U.S. shareholder (and,
if certain tax treaties apply, is attributable to a United States permanent
establishment maintained by such non-U.S. shareholder) and the non-U.S.
shareholder has furnished the Depositary with a properly executed IRS Form
4224 prior to the time of payment.
 
  A non-U.S. shareholder who is eligible for a reduced rate of withholding
pursuant to U.S. income tax treaty must certify such to the Depositary by
providing to the Depositary a properly executed IRS Form 1001 prior to the
time payment is made. A non-U.S. shareholder may be eligible to obtain from
the IRS a refund of tax withheld if such non-U.S. shareholder is able to
establish that no tax (or a reduced amount of tax) is due.
 
  12. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate(s)
representing Shares has been lost, destroyed or stolen, the shareholder should
promptly notify the Depositary by checking the box provided in the box titled
"Description of Shares Tendered" and indicating the number of Shares so lost,
destroyed or stolen. The shareholder will then be instructed by the Depositary
as to the steps that must be taken in order to replace the certificate(s).
This Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen certificates have been
followed. Please allow at least ten to fourteen business days to complete such
procedures.
 
  13. DEFINITIONS. For purposes hereof, the term "Agent's Message" means a
message transmitted by a Book-Entry Transfer Facility to, and received by, the
Depositary and forming a part of a Book-Entry Confirmation, which states that
such Book-Entry Transfer Facility has received an express acknowledgment from
the participant in such Book-Entry Transfer Facility tendering the Shares that
such participant has received and agrees to be bound by the terms of the
Letter of Transmittal and that the Offeror may enforce such agreement against
the participant.
 
  14. PROXY. By executing the Letter of Transmittal as set forth above, a
tendering shareholder irrevocably appoints designees of the Offeror as such
shareholder's proxy, with full power of substitution, in the manner set forth
in the Letter of Transmittal, to the full extent of such shareholder's rights
with respect to the Shares tendered by such shareholder and accepted for
payment by the Offeror (and any and all other Shares or other securities or
rights issued or issuable in respect of such Shares on or after November 3,
1998). All such proxies shall be considered coupled with an interest in the
tendered Shares. This appointment is effective when, and only to the extent
that, the Offeror accepts for payment the Shares deposited with the
Depositary. Upon acceptance for payment, all prior proxies given by the
shareholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent proxies may be given or
written consent executed (and, if given or executed, will not be deemed
effective). The designees of the Offeror will, with respect to the Shares and
other securities or rights, be empowered to exercise all voting and other
rights of such shareholder as they in their sole judgment deem proper in
respect of any annual or special meeting of the Company's shareholders, or any
adjournment or postponement thereof. The Offeror reserves the right to require
that, in order for Shares to be deemed validly tendered, immediately upon the
Offeror's payment for such Shares, the Offeror must be able to exercise full
voting and other rights with respect to such Shares and the other securities
or rights issued or issuable in respect of such Shares, including voting at
any meeting of shareholders (whether annual or special and whether or not
adjourned) in respect of such Shares.

ject to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or im-
prisonment.

FOR IMMEDIATE RELEASE
November 3, 1998

            THE ZIEGLER COMPANIES, INC. SIGNS DEFINITIVE AGREEMENT
                      TO PURCHASE PMC INTERNATIONAL, INC.

     WEST BEND, WIS.--The Ziegler Companies, Inc. [AMEX:ZCO], a financial
services holding company, announced today the signing of a definitive merger
agreement for the acquisition of PMC International, Inc., a Denver-based
investment management and consulting firm.

     Under the terms of the agreement, a subsidiary of The Ziegler Companies
will commence a tender offer to acquire all of the outstanding common stock of
PMC International for $0.60 per share and all of the outstanding preferred stock
of PMC International for $2.50 per share.  Following the completion of the
tender offer, The Ziegler Companies will consummate a second-step merger in
which the remaining PMC International common shareholders will receive $0.60 per
share and its preferred shareholders will receive $2.50 per share.  The total
purchase price for the currently outstanding common and preferred stock,
including PMC International stock warrants and options, is approximately $3.1
million, which will be funded from working capital of The Ziegler Companies.

     To support PMC International during the period in which the companies are
effecting the merger, The Ziegler Companies has executed a $3.5 million credit
facility with PMC International, the outstanding balance of which is convertible
into PMC common stock at $0.60 per share.  On October 15, 1998, the Ziegler
Companies loaned $500,000 for working capital.  In addition, the two firms have
entered into an option for common stock under which The Ziegler Companies may
immediately purchase 4,500,000 shares of PMC common stock for $0.60 per share.

     The Ziegler Companies, Inc., with annual revenues of approximately $75
million, is a holding company headquartered in West Bend, Wis.  The company's
principal subsidiary, B.C. Ziegler and Company, is an investment banking and
brokerage firm. 
<PAGE>
 
Other Ziegler subsidiaries provide services that include asset management,
investment consulting, and reduced-commission brokerage services.

     PMC International, Inc., with annual revenues of approximately $15 million,
provides investment management and consulting services that support the
relationships between financial advisers and their clients.  Its services
include privately managed accounts and mutual fund wrap programs.  The firm has
four subsidiaries, which include Portfolio Management Consultant, Inc., an
investment advisory firm; the company also operates a broker/dealer, an
investment advisory firm specializing in mutual fund asset allocation products,
and a subsidiary which develops proprietary software for the financial services
industry.

     Peter D. Ziegler, president and chief executive officer of The Ziegler
Companies, said, "This acquisition fits strategically with our plans on the
money management side of our business.  It adds $2 billion in assets under
management to Ziegler, and PMC's services complement our existing business
extremely well.  Adding PMC positions us favorably as the financial services
industry moves away from transaction business toward fee-based services."

     The board of directors of PMC International has unanimously approved the
tender offer and recommended that PMC shareholders accept the offer and tender
their shares.  Scott MacKillop, president of PMC International, said, "This
transaction is very exciting for us because it represents the culmination of an
exhaustive 10-month effort to find a strategic partner who could provide the
financial strength, credibility and experience necessary to keep our firm in the
forefront of this highly competitive and growing part of the financial services
industry.  This combination represents a win for our clients, our business
partners and our shareholders."

     This new release contains forward-looking statements made pursuant to the
provisions of the Private Securities Litigation Reform Act of 1995.  Management
of The Ziegler Companies, Inc. and PMC International, Inc. caution that the
projections are based on a current understanding of the PMC International
business, and are highly dependent on a variety of factors which could cause
actual results to differ from these 

                                       2

estimates. These factors include, without limitation, general economic
conditions, market conditions in relevant markets, market acceptance of existing
and new products and services and successful integration of PMC International
with The Ziegler Companies.

                              W I T N E S S E T H:
                              - - - - - - - - - - 



     WHEREAS, the respective Boards of Directors of the Purchaser, the Sub and
the Company have each determined that it is advisable and in the best interest
of each such corporation and its shareholders, on the terms and subject to the
conditions of this Agreement, (a) for the Sub to commence a cash tender offer to

the Company, including scrip (the "Common Stock") and $0.325 Cumulative
Convertible Series A Preferred Stock, without par value, of the Company (the

to merge the Sub into the Company; and



     WHEREAS, the Board of Directors of the Company has adopted resolutions
approving that Offer (as hereafter defined) and the Merger (as hereafter
defined) and recommends that the holders of the Common Stock and Preferred Stock
accept the Offer;



     NOW, THEREFORE, in consideration of the mutual representations, warranties,
covenants and agreements, and upon the terms and subject to the conditions
hereafter set forth, the parties hereto do hereby agree as follows:



                                   ARTICLE I.



                                   THE OFFER



     SECTION 1.01  The Offer.  (a) Provided that this Agreement shall not have
been terminated in accordance with Section 8.01 hereof, as promptly as
practicable (but in any event within five business days of the date of this
Agreement), the Purchaser shall cause the Sub to commence (within the meaning of
Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) an offer to purchase all outstanding shares of Common Stock (including
scrip) and Preferred Stock not owned by the Purchaser or the Sub at a price of
$0.60 per share of Common Stock (including scrip), net to the seller in cash and
$2.50 per share of Preferred Stock, net to the seller in cash, which offer shall
remain open for at least 20 business days (the "Offer") and, subject to the
conditions of the Offer set forth in Exhibit A hereto, shall use its best
efforts to consummate the Offer, including, if necessary, conversion of
convertible loans including a $3,500,000 credit facility and options outstanding
into Common Stock or Preferred Stock of the Company, as the case may be, in
order to consummate the Offer.  The obligations of the Purchaser and the Sub to
consummate the Offer, to accept for payment and to pay for any shares of Common
<PAGE>
 
Stock and Preferred Stock tendered shall be subject only to those conditions set
forth in Exhibit A hereto.

     (b) Neither the Purchaser nor the Sub will, without the prior written
consent of the Board of Directors of the Company, decrease the amount or change
the form of the consideration payable in the Offer, decrease the number of
shares of Common Stock or Preferred Stock sought pursuant to the Offer, change
the conditions to the Offer, impose additional conditions or terms to the Offer,
amend or waive the condition that there be validly tendered and not properly
withdrawn prior to the expiration of the Offer a number of shares of Common
Stock and Preferred Stock which when added to the number of shares of Common
Stock and Preferred Stock owned by the Purchaser and its affiliates constitutes
at least two-thirds of the then outstanding shares of Common Stock and two-
thirds of the then outstanding shares of Preferred Stock, respectively, on a
fully diluted basis, or amend any term of the Offer in any manner adverse to
holders of shares of Common Stock or Preferred Stock.  Assuming the prior
satisfaction or waiver of the conditions to the Offer, the Purchaser covenants
and agrees to accept for payment and pay for, in accordance with the terms of
the Offer, shares of Common Stock and Preferred Stock tendered pursuant to the
Offer as soon as it is permitted to do so under applicable Law, provided that
the Purchaser and the Sub shall have the right, upon consultation with the
Company, to extend the Offer (if without such extension the Purchaser would be
unable to consummate the Offer) to a date not later than the 35th business day
following the commencement of the Offer or for such longer period as may be
required by Law.

     (c) Notwithstanding anything to the contrary in this Agreement, the
Purchaser and the Sub further agree that, subject to the terms and conditions of
this Agreement, in the event that the conditions to the Offer set forth in
paragraphs (a) or (b) of Exhibit A hereto shall occur or exist (and shall not
have been waived), the Sub shall, at the Company's request, extend the Offer to
a date not later than the 40th business day following the commencement of the
Offer; provided, however, if the condition set forth in paragraph (d)(i) of
Exhibit A shall not have been satisfied, the Purchaser and the Sub shall, if
reasonably requested by the Company, extend the Offer for five business days to
enable the Company to cure such breach.

     (d) As soon as practicable on or before the date of commencement of the
Offer, but not later than five business days after the execution of this
Agreement, the Purchaser and the Sub shall file with the Securities and Exchange
Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1 with respect
to the Offer which will contain the offer to purchase and form of the related
letter of transmittal (together with any supplements or amendments thereto, the
"Offer Documents").  The Offer Documents will comply in all material respects
with the provisions of applicable federal securities Laws and, on the date filed
with the SEC and on the date first published, sent or given to the holders of
the Common Stock and Preferred Stock of the Company, shall not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that no representation is made by the Purchaser or the Sub with respect to
information supplied by the Company in writing for inclusion in the Offer
Documents.  The Purchaser, the Sub and the Company each agrees promptly to
correct any information provided by it for use in the Offer Documents if and to
the extent that it shall be

                                      -2-
<PAGE>
 
discovered to have been or to have become false or misleading in any material
respect and the Purchaser and the Sub each further agrees to take all steps
necessary to cause the Offer Documents as so corrected to be filed with the SEC
and disseminated to the holders of the Common Stock and Preferred Stock of the
Company, in each case as and to the extent required by applicable federal
securities Laws.  The Purchaser and the Sub agree to provide the Company and its
counsel in writing with any comments the Purchaser, the Sub or their counsel may
receive from the SEC or its staff with respect to the Offer Documents promptly
after the receipt of such comments.

     SECTION 1.02  Company Actions.  The Company hereby consents to the Offer,
recommends its acceptance by the Company's shareholders and represents that (a)
its Board of Directors or a duly authorized committee thereof (at a meeting duly
called and held) has (i) determined that the Offer and the Merger (as
hereinafter defined) taken together, are fair to the holders of the Common Stock
and Preferred Stock of the Company and (ii) resolved, subject to its fiduciary
duties under applicable Laws as advised by counsel, to recommend acceptance of
the Offer and approval and adoption of this Agreement by the holders of the
Common Stock and Preferred Stock of the Company, and (b) Value Investing
Partners, Inc. has advised the Company's Board of Directors that the $0.60 per
share of Common Stock and $2.50 per share of Preferred Stock cash consideration
to be received by holders of Common Stock and Preferred Stock of the Company,
respectively, in the Offer and the Merger, taken together, is fair to such
shareholders (other than the Purchaser and its affiliates) from a financial
point of view.  The Company hereby agrees to file with the SEC as soon as
practicable after the commencement of the Offer a Solicitation/Recommendation
Statement on Schedule 14D-9 (together with any amendments or supplements
thereto, the "Schedule 14D-9") containing the recommendations described in the
first sentence of this Section 1.02.  The Company, the Purchaser and the Sub
each agrees promptly to correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that it shall be discovered to have been or
to have become false or misleading in any material respect and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and disseminated to the holders of the
Company's Common Stock and Preferred Stock and to the extent required by
applicable federal securities Laws.  The Company agrees to provide the Purchaser
and the Sub and their counsel, in writing, with any comments the Company or its
counsel may receive from the SEC or its Staff with respect to the Schedule 14D-9
promptly after the receipt of such comments. Notwithstanding anything contained
in this Section 1.02, if the Board of Directors of the Company determines in the
exercise of its fiduciary duties to withdraw, modify or amend its
recommendation, such withdrawal, modification or amendment shall not constitute
a breach of this Agreement.  The Company hereby consents to the inclusion in the
Offer of the recommendation referred to in the first sentence of this Section
1.02.  In connection with the Offer, the Company will promptly furnish the
Purchaser with mailing labels, security position listings and any available
listing or computer file containing the names and addresses of the record
holders of the shares of Common Stock and Preferred Stock as of a recent date
and will furnish the Purchaser with such information and assistance as the
Purchaser or its agents may reasonably request in communicating the Offer to the
holders of the Common Stock and Preferred Stock of the Company.  Subject to the
requirements of applicable Law, and except for such steps as are necessary to
disseminate the documents constituting the Offer and any other documents
necessary to consummate the Merger, the Purchaser and the Sub and each of their
affiliates and associates shall hold in confidence the information contained in
any of such labels, listings and files, will use such information only in
connection with the Offer and the

                                      -3-

Merger, and, if this Agreement is terminated, will deliver to the Company the
information and all copies of such information then in their possession and in
the possession of their legal, accounting and financial advisors.

     SECTION 1.03  Directors.  (a)  Promptly upon the purchase by the Purchaser
or any of its affiliates of such number of shares of Common Stock which, when
added to the number of shares of Common Stock owned by the Purchaser and the
Sub, represents at least two-thirds of the outstanding shares of Common Stock,
and from time to time thereafter, the Purchaser shall be entitled to designate
such number of directors, rounded up to the next whole number, on the Board of
Directors of the Company as will give the Purchaser, subject to compliance with
Section 14(f) of the Exchange Act, representation on the Board of Directors of
the Company equal to the product of the number of directors on the Board of
Directors of the Company and the percentage that such number of shares of Common
Stock so owned bears to the number of shares of Common Stock outstanding, and
the Company, through action of its Board of Directors, if necessary, shall, upon
request by the Purchaser, promptly, at the Company's election, either increase
the size of the Board of Directors of the Company or exercise its reasonable
best efforts to secure the resignations of such number of directors as is
necessary to enable the Purchaser's designees to be elected to the Board of
Directors of the Company and shall cause the Purchaser's designees to be so
elected to the Board of Directors.

     (b) The obligations to appoint designees to its Board of Directors
hereunder shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder.  The Company shall promptly take all actions required
pursuant to Section 14(f) and Rule 14f-1 in order to fulfill the obligations
under this Section 1.03 and shall include in the Schedule 14D-9 such information
with respect to the Company and its officers and directors as is required under
Section 14(f) and Rule 14f-1 to fulfill its obligations under this Section 1.03.
The Purchaser will supply to the Company, in writing, and be solely responsible
for any information with respect to itself and its nominees, officers, directors
and affiliates required by Section 14(f) and Rule 14f-1.

     (b) Each share of Preferred Stock issued and outstanding immediately prior
to the Effective Time (other than shares of Preferred Stock owned by the
Purchaser or any affiliate of the Purchaser or held in the treasury of the
Company, and Dissenting Shares (as defined in Section 3.01 hereof) representing

or to perfect the right to receive payment for such shares pursuant to Article
113 of Title 7 of the Colorado Revised Statutes and Section 3.01 hereof if such
holder has validly exercised and not withdrawn such right to receive payment for
such shares.

     (c) Each share of Common Stock and Preferred Stock held by the Pur chaser
or any of its affiliates or held in the Company's treasury or by a subsidiary of

     (d) The Purchaser and the Sub acknowledge that each share of Common Stock
outstanding immediately prior to the date hereof which was granted to

hereof) as of the date of acquisition of shares of Common Stock pursuant to the
Offer, will become fully vested and free of any and all restrictions to which
such shares of Common Stock are otherwise subject.

     (e) Each certificate for scrip issued and outstanding immediately prior to
the Effective Time shall, as of the Effective Time, and by virtue of the Merger
and without any action on the part of the holder thereof, be converted into the

the holder in cash or any higher price paid per share of Common Stock  pursuant
to the Offer, payable to the holder thereof, without interest thereon, upon the
surrender of the certificate formerly representing such scrip.  At and after the

a holder of scrip of the Company, except for the right to surrender such
certificate or certificates in exchange for the Common Stock Merger
Consideration.

with their terms, all options, stock option plans, programs, arrangements or
agreements pursuant to which Options have or may be granted by the Company

further force and effect whatsoever, without the necessity for any additional
notice or action by the Surviving Corporation under the applicable Stock Option
Plans or otherwise.  Each warrant to purchase Common Stock of the Company issued

     SECTION 2.09  Shareholders' Meeting.  If approval by the Company's
shareholders is required by applicable Law in order to consummate the Merger,
the Company, acting through its Board of Directors, shall, in accordance with
applicable Law:

     (a) duly call, give notice of, convene and hold an annual or special
meeting (the "Shareholders' Meeting") of holders of shares of Common Stock and
Preferred Stock of the Company as soon as practicable following the consummation
of the Offer for the purpose of considering and taking action on this Agreement;

     (b) subject to its fiduciary duties under applicable Laws as advised by
counsel, include in the Proxy Statement (as hereinafter defined) the
recommendation of the Board of Directors that shareholders of the Company vote
in favor of the approval and adoption of this Agreement; and

     (c) use its best efforts (i) if a Proxy Statement or Information Statement,
as selected by the Purchaser, is required to be filed, to obtain and furnish the
information required to be included by it in the Proxy Statement, and, after
consultation with the Purchaser, respond promptly to any comments made by the
SEC with respect to the Proxy Statement and any preliminary version thereof and
cause the Proxy Statement to be mailed to its shareholders at the earliest
practicable time following the expiration of the Offer, and (ii) subject to
fiduciary duties of the Board of Directors under applicable Law as advised by
counsel, to obtain the necessary approvals of the Merger and this Agreement by
its shareholders.  The Purchaser agrees that, at the Shareholders' Meeting, all

or otherwise by the Purchaser, the Sub or any other affiliate of the Purchaser
will be voted in favor of the Merger and this Agreement.

     SECTION 2.10  Merger Without Meeting of Shareholders.  Notwithstanding the
foregoing, if, following the completion of the Offer, the Merger may be
consummated under Colorado Law without a vote of the Company's shareholders, the
parties hereto agree to take all necessary and appropriate action to cause the
Merger to become effective without a meeting of the shareholders, as soon as
practicable after the acquisition of shares of Common Stock and Preferred Stock
pursuant to the Offer, but in no event later than 30 days thereafter.

     SECTION 2.11  Closing.  Upon the terms and subject to the conditions
hereof, as soon as practicable after consummation of the Offer, and if required
by Law, after the vote of the shareholders of the Company in favor of the
adoption of this Agreement has been obtained, the Company (or the Purchaser or
the Sub, if appropriate) shall execute in the manner required by the Colorado
Law and deliver to the Secretary of State of the State of Colorado the duly
executed articles of merger, and the parties shall take all such other and
further actions as may be required by Law to make the Merger effective.  Prior
to the filing referred to in this Section, a closing (the "Closing") will be
held at the offices of the Company (or such other place as the parties may
agree) for the purpose of confirming all the foregoing.

                                 ARTICLE III.

                  DISSENTING SHARES; EXCHANGE OF CERTIFICATES


          SECTION 3.01  Dissenting Shares.  Notwithstanding anything in this
Agreement to the contrary, in the event that appraisal rights are available in
connection with the Merger pursuant to Colorado Law, shares of Common Stock or
Preferred Stock which are issued and outstanding immediately prior to the
Effective Time and which are held by shareholders who did not vote in favor of
the Merger and who comply with all of the relevant provisions of Article 113 of
Title 7 of the Colorado Revised Statutes (the "Dissenting Shares") shall not be
converted into or be exchangeable for the right to receive the Common Stock
Merger Consideration or the Preferred Stock Merger Consideration, as
appropriate, unless and until such holders shall have failed to perfect or shall
have effectively withdrawn or lost their rights to appraisal under Colorado Law.
If any such holder shall have failed to perfect or shall have effectively
withdrawn or lost such right, such holder's shares of Common Stock or Preferred
Stock shall thereupon be deemed to have been converted into and to have become
exchangeable for the right to receive, as of the Effective Time, the Common
Stock Merger Consideration or Preferred Stock Merger Consideration, as
appropriate, without any interest thereon.

          SECTION 3.02  Exchange of Certificates.  (a)  The Purchaser shall
deposit or cause to be deposited in trust for the benefit of the Surviving
Corporation with an exchange agent selected by the Purchaser (the "Exchange
Agent") at the Effective Time cash in an aggregate amount necessary to make the
payments pursuant to Section 2.06 hereof to holders (other than the Purchaser,
or the Sub or any of their respective affiliates) of shares of Common Stock and
Preferred Stock that are issued and outstanding immediately prior to the
Effective Time (such amounts being hereinafter referred to as the "Exchange
Fund").  The Exchange Agent shall, pursuant to irrevocable instructions, make
the payments provided for in the preceding sentence out of the Exchange Fund.
The Exchange Agent shall invest the Exchange Fund as the Purchaser directs,
provided that all such investments shall be in obligations of or guaranteed by
the United States of America, in commercial paper obligations receiving the
highest rating from either Moody's Investors Services, Inc. or Standard & Poor's
Corporation, or in certificates of deposit, bank repurchase agreements or
banker's acceptances of commercial banks with capital exceeding $50 million.
The Exchange Fund shall not be used for any other purpose, except as provided in
this Agreement.  If for any reason (including, without limitation, losses
sustained by such investments) the Exchange Fund is inadequate to pay the amount
holders of Common Stock and Preferred Stock shall be entitled to hereunder, the
Surviving Corporation shall remain solely liable for the payment thereof.

          (b) Promptly after the Effective Time, the Surviving Corporation shall
cause the Exchange Agent to mail to each record holder, as of the Effective
Time, other than the Purchaser or any of its affiliates and other than holders
of Dissenting Shares, of an outstanding certificate or certificates which
immediately prior to the Effective Time represented scrip shares or shares of
Common Stock or Preferred Stock (the "Certificates") a form of letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent) and instructions for use in effecting the
surrender of the Certificate for payment therefor.  Upon surrender to the
Exchange

                                      -8-
<PAGE>
 
Agent of a Certificate, together with such letter of transmittal duly executed,
and any other required documents, the holder of such Certificate shall be paid
in exchange therefor cash in an amount equal to the product of the amount of
scrip or the number of shares of Common Stock, formerly represented by such
Certificate multiplied by the Common Stock Merger Consideration or the number of
shares of Preferred Stock formerly represented by such Certificate multiplied by
the Preferred Stock Merger Consideration, respectively, and such Certificate
shall forthwith be canceled. No interest will be paid or accrued on the cash
payable upon the surrender of the Certificates.  If payment is to be made to a
person other than the person in whose name the Certificate surrendered is
registered, it shall be a condition of payment that the Certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the Certificate surrendered or establish to the satisfaction of the
Surviving Corporation that such tax has been paid or is not applicable.  Until
surrendered in accordance with the provisions of this Section 3.02, each
Certificate (other than Certificates representing shares of Common Stock or
Preferred Stock owned by the Purchaser or any affiliate of the Purchaser, and
Dissenting Shares) shall represent for all purposes the right to receive the
Common Stock Merger Consideration or Preferred Stock Merger Consideration, as
appropriate, in cash multiplied by the number of shares of scrip, Common Stock
or Preferred Stock, respectively, evidenced by such Certificate, without any
interest thereon.

          (c) After the Effective Time, there shall be no transfers of shares of
Common Stock or Preferred Stock or of scrip which were outstanding immediately
prior to the Effective Time on the stock transfer books of the Surviving
Corporation.  If, after the Effective Time, Certificates are presented to the
Surviving Corporation, they shall be canceled and exchanged for cash as provided
in this Article III.  As of the Effective Time, the stock ledger of the Company
shall be closed.

          (d) Any portion of the Exchange Fund (including the proceeds of any
investments thereof) that remains unclaimed by the holders of scrip or the
shareholders of the Company for six months after the Effective Time shall be
paid to the Surviving Corporation.  Any shareholders of the Company who have not
theretofore complied with Section 3.01 hereof shall thereafter look only to the
Surviving Corporation for payment of their claim for the Common Stock Merger
Consideration or Preferred Stock Merger Consideration, as appropriate, without
any interest thereon.



                                  ARTICLE IV.



                         REPRESENTATIONS AND WARRANTIES

                                 OF THE COMPANY



          The Company represents and warrants to the Purchaser and the Sub as
follows:

          SECTION 4.01  Organization and Qualification.  The Company is a
corporation duly organized, validly existing and in good standing under the Laws
of the State of Colorado and

                                      -9-
<PAGE>
 
has all requisite corporate power and authority to carry on its business as it
is now being conducted. The Company is duly qualified as a foreign corporation
and is in good standing in each jurisdiction in which the property owned, leased
or operated by it or the nature of the business conducted by it makes such
qualification necessary, except where the failure to be in good standing or so
qualified would not have a Material Adverse Effect.  Each of the Company's
wholly owned subsidiaries is duly organized, validly existing and in good
standing under the applicable laws of its state of incorporation.

          SECTION 4.02  Capitalization.  The authorized capital stock of the
Company consists of (a) 50,000,000 shares of Common Stock, par value $.01 per
share, of which, as of October 22, 1998, 4,446,828.5 shares were issued and
outstanding (including scrip) and (b) 5,000,000 shares of Preferred Stock,
without par value, of which 450,000 shares have been designated as $0.325
Cumulative Series A Preferred Stock ("Preferred Stock"), of which, as of October
22, 1998, 138,182 shares were issued and outstanding.  All of the issued and
outstanding shares of capital stock of the Company have been duly authorized and
validly issued and are fully paid and nonassessable and free of preemptive
rights.  As of October 22, 1998, 943,290 shares of Common Stock and no shares of
Preferred Stock were reserved for issuance and issuable upon or otherwise
deliverable in connection with the exercise of all outstanding Options under the
Stock Option Plans or warrants.  Except as set forth above and except for the
conversion rights granted to the Purchaser in that certain Convertible
Promissory Note given by the Company, dated October 15, 1998 (the "Note) and the
$3,500,000 credit facility being entered into by the Purchasers concurrently
with this Agreement and the options to purchase 4,500,000 shares of Common Stock
and the options to purchase 111,818 shares of Preferred Stock granted to
Purchaser, there are not as of the date hereof, and at the Effective Time there
will not be, any outstanding or authorized subscriptions, options, warrants,
calls, rights, commitments or any other agreements of any character obligating
the Company to issue any additional shares of Common Stock, Preferred Stock or
any other shares of capital stock of the Company or any other securities
convertible into or evidencing the right to subscribe for any such shares.

          SECTION 4.03  Corporate Power and Authority.  The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby.  The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated hereby have been duly authorized by the Board of
Directors of the Company and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or to consummate the
transactions so contemplated (other than, with respect to the Merger, if
required, the approval and adoption of this Agreement by the Company's
shareholders).  This Agreement has been duly and validly executed and delivered
by the Company and, assuming this Agreement constitutes a valid and binding
obligation of each of the Purchaser and the Sub, this Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against it in
accordance with its terms.

          SECTION 4.04  Reports.  (a)  Except as set forth in Schedule 4.04,
since January 1, 1997, the Company has filed all required forms, reports and
documents with the SEC required to be filed by it pursuant to the federal
securities Laws and the SEC's rules and regulations thereunder, all of which
have complied, after giving effect to all amendments thereof filed prior to

                                      -10-
<PAGE>
 
the date hereof, in all material respects with all applicable requirements of
the Securities Act of 1933, as amended (the "Securities Act"), and the Exchange
Act, and the rules promulgated thereunder (collectively, the "SEC Reports").
None of the SEC Reports, including without limitation any financial statements
or schedules included therein, at the time filed, contained any untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.

          (b) The consolidated balance sheets and the related consolidated
statements of net earnings and of changes in financial position (including the
related notes thereto) of the Company included in the SEC Reports fairly present
the consolidated financial position of the Company and its subsidiaries as of
their respective dates, and the results of consolidated operations and changes
in consolidated financial position for the periods presented therein, all in
conformity with generally accepted accounting principles applied on a consistent
basis (subject, in the case of the unaudited interim financial statements, to
normal year-end adjustments), except as otherwise noted therein, and except that
the quarterly financial statements do not contain all of the footnote
disclosures required by generally accepted accounting principles.

          SECTION 4.05  Offer Documents; Proxy Statement; Information Statement;
Other Information.   The letter to shareholders, notice of meeting, proxy
statement and form of proxy, or the information statement, as the case may be
and as selected by Purchaser, to be distributed to shareholders in connection
with the Merger, are collectively referred to herein as the "Proxy Statement".
The Schedule 14D-9 and, if required for the consummation of the Merger under
applicable Law, the Proxy Statement will comply in all material respects with
the applicable federal securities Laws and, on the date filed with the SEC,
shall not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that no representation is made by the Company with
respect to information supplied by the Purchaser or any affiliate of the
Purchaser, in writing, for inclusion in the Schedule 14D-9 or the Proxy
Statement or any amendments or supplements thereto.  None of the information
relating to the Company and its subsidiaries supplied in writing by the Company
for inclusion in the Offer Documents or the Proxy Statement, including any
amendments or supplements to either of the foregoing, or any schedules required
to be filed with the SEC in connection therewith, will, at the respective times
the Offer Documents or Proxy Statement or any amendments or supplements thereto
are filed with the SEC or mailed to the shareholders of the Company, as the case
may be, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

          SECTION 4.06  Consents and Approvals; No Violation.  Neither the
execution and delivery of this Agreement by the Company nor the consummation by
the Company of the transactions contemplated hereby will (i) conflict with or
result in a breach of any provision of the Articles of Incorporation or By-laws
of the Company or its subsidiaries; (ii) require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority, except (A) pursuant to the applicable requirements of
the Exchange Act, the Investment

                                      -11-
<PAGE>
 
Advisers Act of 1940, as amended (the "Advisers Act"), and the rules and
regulations of the NASD (as defined hereafter), (B) the filing of the articles
of merger  pursuant to the Colorado Law, or (C) where the failure to obtain such
consent, approval, authorization or permit, or to make such filing or
notification, would not in the aggregate have a Material Adverse Effect or a
material adverse effect on the consummation of the transactions contemplated
hereby; or (iii) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to the Company or its subsidiaries, except for violations
which would not in the aggregate have a Material Adverse Effect or a material
adverse effect on the consummation of the transactions contemplated hereby.

          SECTION 4.07  Brokerage Fees and Commissions.  Except for those fees
and expenses payable to Value Investing Partners, Inc. and Putnam, Lovell, De
Guardiola & Thornton, Inc. collectively limited to less than $276,000, the
Company hereby represents and warrants to the Purchaser with respect to the
Company, that no person or entity is entitled to receive from the Company, or
any of its subsidiaries any investment banking, brokerage or finder's fee in
connection with this Agreement or the transactions contemplated hereby based
upon arrangements made by or on behalf of the Company.

          SECTION 4.08  Events Subsequent to June 30, 1998.  Except as described
on Schedule 4.08, in the Company's Form 10-QSB for the quarter ended June 30,
1998, as amended as of September 16, 1998, or related to transactions involving
the Purchaser or the Purchaser's affiliates since June 30, 1998, there has not
been any material adverse change in the business, financial condition,
operations, results of operations, or future prospects of the Company and its
subsidiaries.  Without limiting the foregoing, since that date and except as
provided in Schedule 4.08:

               (i) The Company and its subsidiaries have not sold, leased,
     transferred, or assigned any of its assets, tangible or intangible other
     than for a fair consideration in the ordinary course of business;

past practices); (xi) except as required by applicable Laws, adopt or amend any
bonus, profit sharing, compensation, stock option, pension, retirement, deferred
compensation, severance, termination, employment or other employee benefit plan,
agreement, trust, fund, policy or other arrangement for the benefit or welfare
of any registered representative, agent, employee or director or former employee

of business, increase the compensation or fringe benefits of any employee or pay
any employee or pay any benefit not required by any existing plan, arrangement
or agreement; (xii) make any tax election or settle or compromise any federal,
state, local or foreign income tax liability, except in the ordinary course of
business and consistent with past practice; (xiii) agree in writing or otherwise
to take any of the foregoing actions or (xiv) fail to comply in all material
respects with all applicable Laws.  Following the date of this Agreement, the
Company will review its financing documents to determine if the consent of any
third party is required in connection with the transactions contemplated hereby.
If following such review, the Company becomes actually aware that any such
consent is required, it will so notify the Purchaser, and the parties hereto
shall use their respective best efforts to secure such consent; provided,
however, that for this purpose "best efforts" shall not require the Company or
the Purchaser to make any payment in order to secure any such consents.

          SECTION 6.02  No Solicitation.  Neither the Company nor any of its
subsidiaries, nor any of their respective officers, directors, employees,
representatives, agents or affiliates, shall, directly or indirectly, encourage,
solicit, initiate or, except as is required in the exercise of the fiduciary
duties of the Company's directors and officers under applicable Laws upon advice
of counsel to the Company, participate in any way in discussions or negotiations
with, or knowingly provide any information to, any corporation, partnership,
person or other entity or group (other than the Purchaser or any affiliate or an
associate of the Purchaser) concerning any merger, sale of substantially all the
assets, sale of shares of capital stock or similar transactions involving the
Company or any material subsidiary or division of the Company; provided,
however, that nothing contained in this Section 6.02 shall prohibit the Company
or its Board of Directors from (i) taking and disclosing to the Company's
shareholders a position with respect to a tender offer by a third party pursuant
to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act, (ii) making such
disclosure to the Company's shareholders which, in the judgment of the Board of
Directors with the advice of counsel, may be required under applicable Law or
(iii) providing information to, or parti  cipating in discussions or
negotiations with, any party that has actually made, and which the Board of
Directors believes in good faith would be capable of effecting an acquisition of
the Company on terms that are superior, from a financial point of view, to the
Offer and the Merger if the Board of Directors in good faith believes, upon the
written advice of counsel, that the failure to so disclose would constitute a
breach of their fiduciary duty to the Company and its shareholders.  The Company
will promptly communicate to the Purchaser if it is furnishing information to or
engaging in negotiations with any third party with respect to the acquisition of
the Company or any of its assets or subsidiaries.

          SECTION 6.03  Access to Information.   Subject to the existing
confidentiality agreement among the parties, the Company and its subsidiaries
will, upon reasonable notice to Maureen Dobel or her designee, allow the
Purchaser and its authorized representatives reasonable access during regular
business hours to its offices, other facilities and books and records.  The
Company will also make its employees available for interviews with the
Purchaser, with Company personnel present, for reasonable purposes in a manner
reasonably acceptable to Ms. Dobel.

          SECTION 6.04  Notification of Certain Matters.  Each of the Company
and the Purchaser shall give prompt notice to the other party of any notice or
other communication from (i) the SEC, NASD or any other regulatory body relating
to the Merger, the Offer or any of the transactions contemplated by this
Agreement or (ii) any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement.

          SECTION 6.05  Best Efforts.  Subject to the terms and conditions
herein provided, and with respect to the Company, to the fiduciary duties of the
Board of Directors of the Company under applicable Laws, each of the parties
hereto agrees to use its best efforts to take, or cause to be taken, all
appropriate action, and to do, or cause to be done, all things necessary, proper
or advisable under applicable Laws and regulations to consummate and make
effective the transactions contemplated by this Agreement, including, in the
case of the Purchaser and the Sub, the filings required under the Colorado
Securities Act, as amended, with respect to the Offer and Merger and, in the
case of the Company,  obtaining the consents of the fiduciary clients pursuant
to

                                      -22-
<PAGE>
 
Section 6.11 hereof.  In case at any time after the Effective Time any further
action is necessary or desirable to carry out the purposes of this Agreement,
the proper officers and directors of each party to this Agreement shall take all
such necessary action.

          SECTION 6.06  Indemnification and Insurance.  (a)  The Purchaser will
honor the Surviving Corporation's performance of all contracts, agreements and
commitments of the Company or any of its subsidiaries, including those reflected
in their Articles of Incorporation and Bylaws, which indemnify any officer or
director of the Company or any of its subsidiaries, as disclosed on Schedule
6.06(b), against claims made against them arising from their service, but only
to the extent that such contract, agreement or commitment was entered into
before the date of this Agreement and is listed on Schedule 6.06.

          (b) Any indemnified party wishing to claim indemnification under this
Section, upon learning of any such action, suit, claim, proceeding or
investigation, shall promptly notify the Purchaser and the Surviving Corporation
thereof and the Purchaser and the Surviving Corporation shall cooperate in the
defense of any such matter; provided, however, that any failure so to notify the
Purchaser and the Surviving Corporation of any obligation to indemnify such
indemnified party or of any other obligation imposed by this Section shall not
affect such obligations unless such failure to so notify materially prejudices
the rights of the Purchaser and the Surviving Corporation to defend any such
action, suit, claim, proceeding or investigation.  The indemnified parties as a
group shall retain only one counsel in each jurisdiction to represent them with
respect to any single action; provided, however, in the event that there is,
under applicable standards of professional conduct, a conflict between the
positions of any two or more indemnified parties, the Purchaser and such
indemnified parties may retain, at the expense of the Purchaser and the
Surviving Corporation, as the case may be, such number of additional counsel as
are necessary to eliminate all conflicts of the type referred to above.

          (c) In the event any claim is made against directors, officers or
employees of the Company that is covered or potentially covered by insurance,
the Surviving Corporation and the Purchaser shall do nothing that would in their
reasonable discretion forfeit, jeopardize, restrict or limit the insurance
coverage available for that claim until the final disposition of that claim.

          (d) The Surviving Corporation and the Purchaser agree that until six
years from the date hereof, the Articles and the Bylaws of the Surviving
Corporation will not be amended to reduce or limit the rights to indemnity
currently afforded thereunder.  To the knowledge of the Company, there are no
pending or threatened claims which are reasonably anticipated to result in a
claim for indemnification.

          SECTION 6.07  Company Indebtedness.  Prior to the Effective Time, the
Company shall cooperate with the Purchaser in taking such actions as are
reasonably appropriate or necessary in connection with the redemption,
prepayment, modification, satisfaction or elimination of any outstanding long-
term indebtedness of the Company or any of its subsidiaries with respect to
which a consent is required to be obtained to effectuate the Merger and the
transactions contemplated by this Agreement and has not been so obtained
(provided that prior to consummation of the Merger, the Company shall not be
required to actually redeem, prepay, modify, satisfy or

                                      -23-
<PAGE>
 
eliminate any such outstanding long-term indebtedness, make any payment or
undertake any obligation in order to secure any such consents or take any steps
which would irrevocably lead to any of the foregoing).

          SECTION 6.08  Benefit Plans.  (a)  Schedule 6.08(a) includes all
employee benefit plans, programs, policies and agreements which provide
compensation or other benefits upon a termination of employment, voluntary or
involuntary, for the 20 highest paid employees of the Company or its
subsidiaries or which include a "change of control" provision, and a complete
and correct copy (or model form) of each such plan, program, policy and
agreement has been provided to Purchaser.  Schedule 6.08(a) also sets forth the
annual compensation and average annual compensation, as the case may be, as of
the date of this Agreement for purposes of calculating the amount payable for
each of the 20 highest paid employees of the Company or its subsidiaries and any
other employee covered by a change of control provision under any of the plans,
programs, policies and agreements listed on Schedule 6.08(a).

          (b) If any salaried or non-union hourly employee of the Company or any
of its subsidiaries is or becomes a participant in any written employee benefit
plan or program of the Purchaser or any member of its controlled group within
the meaning of Section 414(b) or (c) of the Internal Revenue Code of 1986, as
amended (the "Code"), such employee shall be credited under such plan or program
with all service prior to the Effective Time with the Company and its
subsidiaries (and any predecessor employer) to the extent credit was given by
the Company and its subsidiaries for purposes of eligibility for all purposes
and vesting under such plan or program.

          (c) The Purchaser and the Sub acknowledge that consummation of the
Offer will constitute a change of control of the Company (to the extent such
concept is relevant) for purposes of any and all of the agreements and plans
specified on Schedule 6.08(a).

          SECTION 6.09  No Default.  From the date of this Agreement to the
Effective Date, the Company shall not do any act or omit to do any act, or
permit any act or omission to act, which will cause a material breach of any
material contract to which the Company and/or its subsidiaries is a party.

          SECTION 6.10  Preservation of Relationships.  From the date of this
Agreement to the Effective Date, the Company and its subsidiaries shall use
reasonable best efforts to preserve their business organization intact, to
retain the services of their present officers and key employees and to preserve
the goodwill of suppliers, customers, creditors and others having material
business relationships with them.

          SECTION 6.11  Obtaining Consents.  The Company and its subsidiaries
shall use their reasonable best efforts to obtain consents to the assignments of
the contracts under the Advisers Act, as amended, required for the consummations
of transactions contemplated hereby.

Directors of the Company (excluding any representative of the Purchaser or an
affiliate of the Purchaser), the Purchaser and the Sub;

          (b) by either the Purchaser or the Company, if the Effective Time

terminate this Agreement under this Section 8.01(b) shall not be available to
any party whose failure to fulfill any obligation

                                      -25-
<PAGE>
 
under this Agreement has been the cause of or resulted in the failure of the
Effective Time to occur on or before such date);

          (c) by either the Purchaser or the Company, if any court of competent
jurisdiction in the United States or other United States governmental body shall
have issued an order, decree or ruling, or taken any other action restraining,

other action shall have become final and non-appealable; provided, however, that

Preferred Stock pursuant to the Offer by the 40th business day following such

shares of Common Stock or Preferred Stock shall have been caused by or resulted
from the failure of the Sub or the Purchaser to perform in any respect its
material covenants and agreements contained in this Agreement or Offer; or (ii)
prior to the purchase of shares of Common Stock and Preferred Stock pursuant to
the Offer, the Board of Directors of the Company shall have withdrawn or
modified in a manner adverse to the Purchaser its approval or recommendation of
the Offer, this Agreement or the Merger, or shall have recommended another
offer, or shall have resolved to do any of the foregoing; provided, however, the
Purchaser shall have no right to terminate this Agreement and abandon the Merger
if the Company withdraws or modifies its recommendation of the Offer, this
Agreement or the Merger, by reason of taking and disclosing to the Company's
shareholders a position contemplated by Rule 14e-2(a)(2) or (3) promulgated
under the Exchange Act with respect to another proposal, and if within ten days
of taking and disclosing to its shareholders the aforementioned position, the
Company publicly reconfirms its recommendation of the Offer, this Agreement or
the Merger and takes and discloses to the Company's shareholders a
recommendation to reject such other proposal as contemplated by Rule 14e-2(a)(1)
promulgated under the Exchange Act; or

provided in Section 1.01 hereof within 20 days following the date of this
Agreement, (B) terminated the Offer or the Offer shall have expired without the

Stock or Preferred Stock pursuant to the Offer by the 40th business day
following such commencement, unless such failure to commence, termination or
failure to pay for shares of Common Stock or Preferred Stock shall have been
caused by or resulted from the occurrence or existence of the condition
described in paragraph (d) or (g) of Exhibit A hereto, or (ii) prior to the
purchase of shares of Common Stock and Preferred Stock pursuant to the Offer,

                                      -26-

(A) a corporation, partnership, person or other entity or group shall have made
a bona fide proposal that the Board of Directors of the Company believes, in
good faith after consultation with its legal and financial advisors, is more
favorable to the Company and its shareholders than the Offer and the Merger and

third party proposal, an offer which the Board of Directors believes, in good
faith after consultation with its legal and financial advisors, is at least as
favorable to the Company's shareholders as such third party proposal, it being
understood that the Company shall remain obligated to pay the fees to the
Purchaser pursuant to Section 9.09 hereof.

          SECTION 8.02  Effect of Termination.  In the event of the termination

this Agreement may be amended by action taken by or on behalf of the Boards of
the Company (excluding any representative of the Purchaser or an affiliate of
the Purchaser), the Purchaser and the Sub at any time before or after adoption
of this Agreement by the shareholders of the Company; provided, however, that,
after any such shareholder approval, no amendment shall be made which decreases
the Common Stock Merger Consideration or Preferred Stock Merger Consideration or
which adversely affects the rights of the Company's shareholders hereunder
without the approval of such shareholders.  This Agreement may not be amended
except by an instrument in writing signed on behalf of all the parties.

          SECTION 8.04  Extension; Waiver.  At any time prior to the Effective
Time, the parties hereto, by action taken by or on behalf of the respective
Boards of Directors of the Company (excluding any representatives or directors
appointed by or elected on behalf of the Purchaser or an affiliate of the
Purchaser), the Purchaser or the Sub, may (i) extend the time for the

<PAGE>
 
          the shareholders of the Company; provided, however, that the Purchaser
          and the Sub shall have used their best efforts to have any such
          decree, order or injunction vacated or reversed, including, without
          limitation, by proffering their willingness to accept an order
          embodying any arrangement required to be made by the Purchaser or the
          Sub pursuant to Section 7.01(b) of the Merger Agreement (and
          notwithstanding anything in this subsection (b) to the contrary, no

          have been true in any respect which is material to the Company and its
          subsidiaries taken as a whole, in each case, when made or (iii) a
          Material Adverse Effect has occurred, provided that the aggregate
          effect under (i), (ii), and (iii) shall be in excess of $250,000; or

               (e) the Board of Directors of the Company shall have publicly
          withdrawn or modified in any material respect adverse to the Purchaser
          its recommendation of the Offer; provided, however, the Purchaser
          shall have no right to terminate the Offer or not accept for payment
          or pay for any scrip or shares of Common Stock or Preferred Stock if
          the Company withdraws or modifies its recommendation of the Offer and
          the Merger, by reason of taking and disclosing to the Company's
          shareholders a position contemplated by Rule 14e-2(a)(2) or (3)
          promulgated under the Exchange Act with respect to another proposal,
          and if within ten days of taking and disclosing to its shareholders
          the aforementioned position, the Company publicly reconfirms its
          recommendation of the Offer and Merger and takes and discloses to the
          Company's shareholders a recommendation to reject such other proposal
          as contemplated by Rule 14e-2(a)(1) promulgated under the Exchange
          Act; or

               (f) the Purchaser and the Company shall have agreed that the
          Purchaser shall terminate the Offer, or

          advisors with assets under management with the Company representing in
          the aggregate at least 80% of the total assets under management by the
          Company as of October 1, 1998.

which, in the reasonable judgment of the Purchaser, makes it inadvisable to
proceed with the Offer or with such acceptance for payment or payments.

convertible promissory note, Ziegler has requested that the Company agree, and

Preferred Stock") in the manner set forth below at a price (the "Exercise
Price") per Company Share of $2.50 payable in cash.

purchase price for the Company Shares so designated by wire transfer of
immediately available funds or certified check or bank check. The Company shall

adjustment as provided in Section 7, all of which, upon their issuance and
delivery in accordance with the terms of this Agreement, will be validly issued,

     9.  Binding Effect; No Assignment; No Third Party Beneficiaries.  This
Agreement shall be binding upon and inure to the benefit of the parties hereto

provided for in this Agreement, neither this Agreement nor the rights or the
obligations of either party hereto are assignable, except by operation of law,
or with the written consent of the other party. nothing contained in this
Agreement, express or implied, is intended to confer upon any person other than
the parties hereto and their respective permitted assigns any rights or remedies
of any nature whatsoever by reason of this Agreement.

     10.  Specific Performance.  The parties recognize and agree that if for any
reason any of the provisions of this Agreement are not performed in accordance
with their specific terms or are otherwise breached, immediate or irreparable
harm or injury would be caused for which money damages would not be an adequate
remedy. Accordingly, each party agrees that, in addition to other remedies, the
other party shall be entitled to an injunction restraining any violation or
threatened violation of the provisions of this Agreement. In the event that any
action should be brought in equity to enforce the provisions of the Agreement,
neither party will allege, and each party hereby waives the defense, that there
is adequate remedy at law.

     11.  Entire Agreement.  This Agreement constitutes the entire agreement
among the parties with respect to the subject matter hereof and thereof and

among the parties or any of them with respect to the subject matter hereof and
thereof.

     12.  Further Assurances.  Each party will execute and deliver all such
further documents and instruments and take all such further action as may be
necessary or in order to consummate the transactions contemplated hereby.

     13.  Validity.  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect. In
the event any court or other competent authority holds any provisions of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery of an amendment to this Agreement in
order, as nearly as possible, to effectuate, to the extent permitted by law, the
intent of the parties hereto with respect to such provision and the economic
effects thereof. If for any reason any such court or regulatory agency
determines that Ziegler is not permitted to acquire the full number of shares of
Company


                                      -4-

<PAGE>
 
Preferred Stock provided in Section 1 hereof (as the same may be adjusted), it
is the express intention of the Company to allow Ziegler to acquire or to
require the Company to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof. Each party agrees
that, should any court or other competent authority hold any provision of this
Agreement or part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action required
herein, the other party shall not be entitled to specific performance of such
provision or part hereof or to any other remedy, including but not limited to
money damages, for breach hereof or of any other provision of this Agreement or
part hereof as the result of such holding or order.

                          CONVERTIBLE PROMISSORY NOTE


$500,000                                                        October 15, 1998


     FOR VALUE RECEIVED, PMC INTERNATIONAL, INC., a Colorado corporation (the
"Borrower"), hereby unconditionally and absolutely promises to pay to the order
of THE ZIEGLER COMPANIES, INC., a Wisconsin corporation (the "Lender"), at the
Lender's office at 215 North Main Street, West Bend, Wisconsin 53095 (or at such
other location as the Lender may from time to time designate), in lawful money
of the United States of America and in immediately available funds, the
principal amount of (a) FIVE HUNDRED THOUSAND AND 00/100 DOLLARS ($500,000) or,
if less, (b) the aggregate unpaid principal amount of all loans made to the
undersigned by the Lender, together with all accrued and unpaid interest thereon
on the earlier to occur of: (i) December 31, 1998; (ii) an Event of Default (as
that term is defined in that certain Loan Agreement (the "Dundee Loan
Agreement") dated as of July 7, 1998 between the Borrower and Dundee Bancorp
Inc.); or (iii) a default occurs under Section 8 of any of those certain
Security Agreements from Borrower and its subsidiaries in favor of Lender, each
of even date herewith (collectively, the "Security Agreement").

     The unpaid principal of this Note shall bear interest from and including
the date hereof until paid in full (both before and after judgment) at a
variable rate equal to the prime rate as published in the Wall Street Journal
(Midwest Edition) and the rate of interest hereunder shall change with each
change in such variable rate.  The Borrower promises to pay interest accrued on
the unpaid principal balance of this Note at the Lender's office specified above
(or at such other location as the Lender may from time to time designate) in
like money and funds on the date the principal amount hereof is due and
continuing monthly thereafter until the principal amount of this Note is paid in
full.

     Whenever any payment to be made hereunder shall be stated to be due on a
day that is not a Business Day, the payment shall be made on the next succeeding
Business Day and such extension of time shall be included in the computation of
the amount of interest due hereunder.  As used in this Note, "Business Day"
means any day other than a Saturday, Sunday or other day on which commercial
banks in New York, New York are required or permitted by law to close.
<PAGE>
 
     In the event that any amount of the principal of, or interest on, this Note
is not paid within five (5) calendar days after the date when due, whether at
stated maturity, by acceleration or otherwise, then the entire principal amount
outstanding shall bear interest at an annual rate equal to two percent (2%) in
excess of the otherwise applicable annual rate until all such overdue amounts
are paid in full. All interest and other amounts payable under this Note shall
be computed for the actual number of days elapsed on the basis of a 360-day
year.

     In the event that any amount of the interest on this Note is not paid
within five (5) calendar days following Borrower's receipt of written notice
that such interest is overdue, the Lender may declare the entire balance of
principal and accrued interest under this Note immediately due and payable. In
the event that (i) the Borrower takes or fails to take any action which
constitutes an admission of inability to pay its debts as they mature; (ii) the
Borrower makes a general assignment for the benefit of creditors or to an agent
authorized to liquidate any substantial amount of its assets; (iii) the Borrower
becomes the subject of any bankruptcy, reorganization, insolvency or analogous
proceeding;(iv) an order is made by any court for the winding-up of the Borrower
or a resolution is passed by the shareholder of the Borrower for its winding-up
or an administrator is appointed by the Borrower; (v) an Event of Default occurs
under the Dundee Loan Agreement; and/or (vi) a default occurs under Section 8 of
the Security Agreement, then, the entire unpaid principal of, and accrued
interest on, this Note shall automatically become immediately due and payable.
The Borrower hereby agrees to pay all fees and expenses incurred by the Lender
or any subsequent holder, including the reasonable fees of counsel, in
connection with the protection and enforcement of the rights of the Lender or
any subsequent holder of this Note, including without limitation the collection
of any amounts due under this Note and the protection and enforcement of such
rights in any bankruptcy, reorganization, insolvency or analogous proceeding
involving the Borrower and any and all proceedings after the entry of judgment
hereof.

     This Note, subordinate only to the Dundee Loan Agreement, is secured, among
other things, pursuant to a General Business Security Agreement from the
Borrower in favor of the Lender and dated as of the date hereof, and may now or
hereafter be secured by one or more other security agreements, mortgages, deeds
of trust, assignments or other instruments or agreements. Lender agrees that the
Note and the security interest securing this Note are subordinate to the note
and security interest securing the note

                                      -2-
<PAGE>
 
granted by Borrower and its subsidiaries pursuant to the Dundee Loan Agreement.

     No provision of this Note is intended to or shall require or permit the
Lender, directly or indirectly, to take, collect or receive in money, goods or
in any other form, any interest (including amounts deemed by law to be interest)
in excess of the maximum rate of interest permitted by applicable law. If any
amount due from or paid by the Borrower shall be determined by a court of
competent jurisdiction to be interest in excess of such maximum rate, the
Borrower shall not be obligated to pay such excess and, if paid, such excess
shall be applied against the unpaid principal balance of this Note or, if and to
the extent that this Note has been paid in full, such excess shall be remitted
to the Borrower.

     The Borrower acknowledges that the holder of this Note may assign, transfer
or sell all or a portion of its rights and interests to and under this Note to
an affiliate of the Lender and that such persons or entities shall thereupon
become vested with all of the rights and benefits of the Lender in respect
hereof as to all or that portion of the Note which is so assigned, transferred
or sold.

     The Borrower and all other parties that at any time may be liable hereon in
any capacity, jointly or severally, waive presentment, demand, protest and
notice of dishonor. The Borrower further waives promptness, diligence, notice of
acceptance and any other notice with respect to any of the obligations evidenced
hereunder and any requirement that the Lender exhaust any rights or take any
action against any other person or entity or any collateral. The Borrower
further hereby waives notice of or proof of reliance by the Lender upon this
Note, and the obligations evidenced hereby shall conclusively be deemed to have
been created, contracted, incurred, renewed, extended, amended or waived in
reliance upon this Note. The Borrower shall make all payments hereunder without
defense, offset or counterclaim. No failure to exercise and no delay in
exercising any rights hereunder on the part of the holder hereof shall operate
as a waiver of such rights. This Note may not be changed orally, but only by an
agreement in writing, which is signed by the party or parties against whom
enforcement of any waiver, change, modification or discharge is sought.

     THE VALIDITY, INTERPRETATION AND ENFORCEMENT OF THIS NOTE AND ANY DISPUTE
ARISING OUT OF OR IN CONNECTION WITH THIS NOTE, WHETHER SOUNDING IN CONTRACT,
TORT, EQUITY OR OTHERWISE, SHALL BE GOVERNED

                                      -3-
<PAGE>
 
BY THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAW PROVISIONS) AND
DECISIONS OF THE STATE OF WISCONSIN.

     ALL DISPUTES ARISING UNDER OR IN CONNECTION WITH THIS NOTE, WHETHER
SOUNDING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE
AND FEDERAL COURTS LOCATED IN MILWAUKEE, WISCONSIN, AND THE COURTS TO WHICH AN
APPEAL THEREFROM MAY BE TAKEN; PROVIDED, HOWEVER, THAT THE LENDER SHALL HAVE THE
RIGHT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TO PROCEED AGAINST THE
BORROWER OR ITS PROPERTY IN ANY LOCATION SELECTED BY THE LENDER TO ENABLE THE
LENDER TO REALIZE ON SUCH PROPERTY, OR TO ENFORCE A JUDGMENT OR OTHER COURT
ORDER IN FAVOR OF THE LENDER. THE BORROWER AGREES THAT IT WILL NOT ASSERT ANY
PERMISSIVE COUNTERCLAIMS, SETOFFS OR CROSS-CLAIMS IN ANY PROCEEDING BROUGHT BY
THE LENDER. THE BORROWER WAIVES ANY OBJECTION THAT THE BORROWER MAY HAVE TO THE
LOCATION OF THE COURT IN WHICH THE LENDER HAS COMMENCED A PROCEEDING, INCLUDING,
WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON FORUM NON
CONVENIENS.

     THE BORROWER AND, BY ITS ACCEPTANCE HEREOF, THE LENDER EACH HEREBY WAIVE TO
THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION
OR PROCEEDING ARISING UNDER OR IN CONNECTION WITH THIS NOTE.

     At the option of the Lender, this Note (solely for the then outstanding
principal at the time of conversion or such lesser amount as selected by the
Lender in a written notice to the Borrower) may be converted, in whole or in
part, without expense to Lender, into Borrower's $.325 Cumulative Convertible
Series A Preferred Stock ("Preferred Stock"). The conversion price shall be
$2.50 for each share of Preferred Stock, subject to adjustment as set forth
below ("Conversion Price"). Upon conversion, any accrued interest shall be paid
in cash in accordance with the original terms.

     The Borrower hereby agrees that at all times the number of shares of
Preferred Stock that will be delivered upon conversion shall be reserved for
exercise of this Note. No fractional shares shall be issued upon conversion of
this Note.

     The Lender, by virtue hereof, shall not be entitled to any rights of a
stockholder in the Borrower, until the Note is converted in whole or in part.

     In case the Borrower shall effect a stock dividend, stock split or reverse
stock split of the outstanding shares of Common Stock or Preferred Stock, the
Conversion Price shall be

                                      -4-
<PAGE>
 
proportionately decreased in the case of a stock dividend or stock split or
increased in the case of a reverse stock split (on the date that such
transaction shall become effective) by multiplying the Conversion Price in
effect immediately prior to the stock dividend or stock split by a fraction, the
numerator of which is the number of shares of Preferred Stock outstanding
immediately prior to such stock dividend or stock split, and the denominator of
which is the number of shares of Preferred Stock outstanding immediately after
such stock dividend or stock split.

     In case of any consolidation or merger of the Borrower with or into another
corporation (other than a merger with a subsidiary, in which merger the Borrower
is the continuing corporation) or in the case of any sale or conveyance to
another corporation of the property of the Borrower as an entirety or
substantially as an entirety, the Borrower shall cause effective provision to be
made so that the Note holder shall have the right thereafter, by exercising this
Note, to purchase the kind and amount of shares of stock and other securities
and property receivable upon such consolidation, merger, sale or conveyance as
may be issued or payable with respect to or in exchange for the number of Shares
of the Borrower theretofore purchasable upon the exercise of this Note had such
consolidation, merger, sale or conveyance not taken place. The foregoing
provision shall similarly apply to successive consolidations, mergers, sales or
conveyances.

     Notwithstanding anything to the contrary, the Borrower shall not be
required to give effect to any adjustment in the Conversion Price unless and
until the net effect of one or more adjustments, determined as above provided,
shall have required a change of the Conversion Price by at least one cent, but
when the cumulative net effect of more than one adjustment so determined shall
be to change the actual Conversion Price by at least one cent, such change in
the Conversion Price thereupon be given effect.

                                      -5-
<PAGE>
 
     Upon any adjustment of the Conversion Price, the Holder of the Note shall
thereafter (until another such adjustment) be entitled to purchase, at the new
Conversion Price, the number of shares, calculated to the nearest full share,
obtained by multiplying the number of Shares initially issuable upon exercise of
this Note by the Conversion Price in effect on the date hereof and dividing the
product so obtained by the new Conversion Price.

rate equal to the prime rate as published in the Wall Street Journal (Midwest
                                                 -------------------

          ---------------                                                  
retire indebtedness owed to Dundee Bancorp Inc. ("Dundee") arising under that

recorded shall be rebuttable presumptive evidence of the principal and interest
owing and unpaid on the Note.  The failure to so record any such amount or any
error in so recording any such amount shall not, however, limit or otherwise

is a corporation duly and validly organized and existing under the Laws of its
jurisdiction of incorporation and has all requisite authority to conduct its

extent that the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'

limitation) concepts of materiality, reasonableness, good faith and fair dealing
(regardless of whether considered in a proceeding in equity or at law).

Borrower or any such Subsidiary or any of their assets is bound except for the

obtained in connection with the transactions contemplated by this Agreement, and

          ---------------------

liability to the PBGC under Section 4062 of ERISA in connection with any Plan.
Notwithstanding any provision to the contrary contained in this Section 4.9,
Borrower shall not be deemed to be in default hereunder solely by reason of

Section 4.9 so long as the sum of (i) the cost of complying with the warranties
contained in this Section 4.9 plus (ii) all fines, penalties, fees and other
costs resulting from such noncompliance would not reasonably be expected to have

VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY
IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN
CONNECTION WITH, THIS AGREEMENT, THE NOTE, THE SECURITY AGREEMENTS, OR ANY OTHER
CREDIT DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE LENDER OR BORROWER.  THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE LENDER ENTERING INTO THIS AGREEMENT.

     9.15  Conversion.  At the option of the Lender, the Note (for the then
           ----------                                                      
outstanding principal and, if desired by Lender, the then outstanding interest,
in part or in whole, at the time of conversion or such lesser amount as selected
by the Lender in a written notice to the Borrower) may be converted, in whole or
in part, without expense to Lender, into Borrower's Common Stock, par value
$.01, ("Common Stock").  The conversion price shall be $.60 for each share of
Common Stock, subject to adjustment as set forth below ("Conversion Price").

     The Borrower hereby agrees that at all times the number of shares of Common
Stock that will be delivered upon conversion shall be reserved for exercise.  No
fractional shares shall be issued upon conversion.

     The Lender, by virtue hereof, shall not be entitled to any rights of a
stockholder in the Borrower, until the Note is converted in whole or in part.

                                      -23-
<PAGE>
 
     In case the Borrower shall effect a stock dividend, stock split or reverse
stock split of the outstanding shares of Common Stock or Preferred Stock, the
Conversion Price shall be proportionately decreased in the case of a stock
dividend or stock split or increased in the case of a reverse stock split (on
the date that such transaction shall become effective) by multiplying the
Conversion Price in effect immediately prior to the stock dividend or stock
split by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately prior to such stock dividend or stock split, and
the denominator of which is the number of shares of Common Stock outstanding
immediately after such stock dividend or stock split.

     In case of any consolidation or merger of the Borrower with or into another
corporation (other than a merger with a subsidiary, in which merger the Borrower
is the continuing corporation) or in the case of any sale or conveyance to
another corporation of the property of the Borrower as an entirety or
substantially as an entirety, the Borrower shall cause effective provision to be
made so that the Note holder shall have the right thereafter, by exercising this
Note, to purchase the kind and amount of shares of stock and other securities
and property receivable upon such consolidation, merger, sale or conveyance as
may be issued or payable with respect to or in exchange for the number of shares
of the common stock of the Borrower theretofore purchasable upon the exercise of
the Note had such consolidation, merger, sale or conveyance not taken place.
The foregoing provision shall similarly apply to successive consolidations,
mergers, sales or conveyances.

     Notwithstanding anything to the contrary, the Borrower shall not be
required to give effect to any adjustment in the Conversion Price unless and
until the net effect of one or more adjustments, determined as above provided,
shall have required a change of the Conversion Price by at least one cent, but
when the cumulative net effect of more than one adjustment so determined shall
be to change the actual Conversion Price by at least one cent, such change in
the Conversion Price thereupon be given effect.

                            STOCK OPTION AGREEMENT


     STOCK OPTION AGREEMENT, dated as of November 3, 1998 by and between The
Ziegler Companies, Inc., a Wisconsin corporation ("Ziegler"), and PMC
International, Inc., a Colorado corporation (the "Company").

     WHEREAS, concurrently with the execution and delivery of this Agreement,
the parties are entering into a $3.5 million credit facility.

     WHEREAS, as a condition to Ziegler's willingness to enter into the $3.5
million credit facility, Ziegler has requested that the Company agree, and the
Company has so agreed, to grant to Ziegler an option with respect to certain
shares of the Company's Common Stock, $.01 par value ("Common Stock"), on the
terms and subject to the conditions set forth herein.

     NOW, THEREFORE, to induce Ziegler to enter into the $3.5 million credit
facility, and in consideration of the mutual covenants and agreements set forth
herein, the parties hereto agree as follows:

          1.   Grant of Option.  The Company hereby grants as of the date hereof
to  Ziegler an irrevocable option (the "Company Option") to purchase 4,500,000
shares of Common Stock, subject to adjustment as provided in Section 7 (such
shares being referred to herein as the "Company Shares"), in the manner set
forth below at a price (the "Exercise Price") per Company Share of $.60 payable
in cash.  The Company Option shall expire on the later of (1) March 31, 1999, or
(2) fifteen (15) days after the date all loans (and interest) from Ziegler and
its affiliates to the Company have been repaid in full and all amounts due to
Ziegler under the Agreement and Plan of Merger have been paid in full ("the
"Expiration Date").

          2.   Exercise of Option.  The Company Option may be exercised by
Ziegler, in whole or in part, at any time or from time to time until the Company
Option expires, without expense to Ziegler.  In the event Ziegler wishes to
exercise the Company Option, Ziegler shall deliver to the Company a written
notice (an "Exercise Notice") specifying the total number of Company Shares it
wishes to purchase.  Each closing of a purchase of Company Shares (a "Closing")
shall occur at a place, on a date and at a time designated by Ziegler in an
Exercise Notice delivered at least two business days prior to the date of the
Closing.  Upon the delivery by Ziegler to the Company of the Exercise Notice and
the applicable aggregate Exercise Price, Ziegler shall be deemed to be the
<PAGE>
 
holder of record of the Company Shares issuable upon such exercise,
notwithstanding that the stock transfer books of the Company may then be closed
or that certificates representing such Company Shares may not then be actually
delivered to Ziegler.

          3.   Closing.  At any Closing, (a) the Company will deliver to Ziegler
or its designee a single certificate in definitive form representing the number
of the Company Shares designated by Ziegler in its Exercise Notice, such
certificate to be registered in the name of Ziegler and to bear the legend set
forth in Section 8, and (b) Ziegler will deliver to the Company the aggregate
purchase price for the Company Shares so designated by wire transfer of
immediately available funds or certified check or bank check.  The Company shall
pay all expenses, and any and all United States federal, state and local taxes
and other charges that may be payable in connection with the preparation, issue
and delivery of stock certificates in the name of Ziegler or its designee.

          4.   Representations and Warranties of the Company.  The Company
represents and warrants to Ziegler that (a) the Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Colorado and has the corporate power and authority to enter into this Agreement,
and to carry out its obligations hereunder, (b) the execution and delivery of
this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or any of
the transactions contemplated hereby, (c) this Agreement has been duly executed
and delivered by the Company, constitutes a valid and binding obligation of the
Company and, assuming this Agreement constitutes a valid and binding obligation
of Ziegler, is enforceable against the Company in accordance with its terms, (d)
the Company has taken all necessary corporate action to authorize and reserve
for issuance and to permit it to issue, upon exercise of the Company Option, and
at all times from the date hereof through the expiration of the Company Option
will have reserved, authorized and unissued Company Shares equal to 4,500,000 of
the outstanding Shares of Common Stock, such amount being subject to adjustment
as provided in Section 7, all of which, upon their issuance and delivery in
accordance with the terms of this Agreement, will be validly issued, fully paid
and nonassessable, (e) upon delivery of the Company Shares to Ziegler against
full payment thereof, Ziegler will acquire the Company Shares free and clear of
all claims, liens, charges, encumbrances and security interests of any nature
whatsoever, (f) the execution and delivery of this Agreement by the Company does
not, and the consummation by the Company of the transactions contemplated hereby
will not, violate, conflict with, or result in a breach of any provision of, or
constitute a default (with or without notice or lapse of time, or both) under,
or result in the termination of, or accelerate the performance required by, or
result in a right of termination, cancellation, or acceleration of any
obligation or the loss of a material benefit under or the creation of a lien,
pledge, security interest or other encumbrance on assets of the Company or any
of its subsidiaries.

          5.   Representations and Warranties of Ziegler.  Ziegler represents
and warrants to the Company that (a) Ziegler is a corporation duly organized,
validly existing under the laws of the State of Wisconsin and has the corporate
power and authority to enter into this Agreement and to carry out its
obligations hereunder, (b) the execution and delivery of this Agreement by
Ziegler and the consummation by Ziegler of the transactions contemplated hereby

Ziegler and no other corporate proceedings on the part of Ziegler are necessary

          6.   Voting of Shares.  Ziegler shall vote any shares of capital stock
acquired by it pursuant to this Agreement, or otherwise beneficially owned
(within the meaning of Rule 13d-3 promulgated under the Securities Exchange Act
of 1934 (the "Exchange Act")) as it sees fit.

          7.   Adjustment Upon Changes in Capitalization.  Without limitation to
any restriction on the Company contained in the Agreement and Plan of Merger,
dated October 29, 1998, among Ziegler, ZACQ Corp., a Colorado corporation and
wholly owned subsidiary of Ziegler, and the Company, in the event of any change
in the Common Stock by reason of stock dividends, stock splits, mergers,
recapitalizations, combinations, exchange of shares or the like, the type and
number of shares or securities subject to the Company Option, and the Exercise
Price per share provided in Section 1, shall be adjusted appropriately to
restore to Ziegler its rights hereunder.  Notwithstanding any other provision of
this Agreement, from the date hereof to the Expiration Date, the Company shall
not, without the prior written consent of Ziegler, issue or sell, or authorize
or propose the issuance or sale of any shares of Common Stock, or securities
convertible into any shares of Common Stock, or any rights, warrants or options
to acquire any shares of Common Stock.

          8.   Restrictive Legends.  Each certificate representing shares of
Company Common Stock issued to Ziegler pursuant to the Option, shall include a
legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
     ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
     AVAILABLE.

It is understood and agreed that:  (i) the reference to the resale restrictions
of the Securities Act in the above legend shall be removed by delivery of
substitute certificate(s) 

                                      -3-
<PAGE>
 
without such reference if Ziegler shall have delivered to the Company a copy of
a letter from the staff of the Securities and Exchange Commission, or an opinion
of counsel, in form and substance reasonably satisfactory to the Company, to the
effect that such legend is not required for purposes of the Securities Act; and
(ii) the reference to the provisions to this Agreement in the above legend shall
be removed by delivery of substitute certificate(s) without such reference if
the shares have been sold or transferred in compliance with the provisions of
this Agreement and under circumstances that do not require the retention of such
reference. In addition, such certificates shall bear any other legend as may be
required by law.

          9.   Binding Effect; No Assignment; No Third Party Beneficiaries.
This Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns.  Except as
expressly provided for in this Agreement, neither this Agreement nor the rights
or the obligations of either party hereto are assignable, except by operation of
law, or with the written consent of the other party. Nothing contained in this
Agreement, express or implied, is intended to confer upon any person other than
the parties hereto and their respective permitted assigns any rights or remedies
of any nature whatsoever by reason of this Agreement.

          10.  Specific Performance.  The parties recognize and agree that if
for any reason any of the provisions of this Agreement are not performed in
accordance with their specific terms or are otherwise breached, immediate or
irreparable harm or injury would be caused for which money damages would not be
an adequate remedy.  Accordingly, each party agrees that, in addition to other
remedies, the other party shall be entitled to an injunction restraining any
violation or threatened violation of the provisions of this Agreement.  In the
event that any action should be brought in equity to enforce the provisions of
the Agreement, neither party will allege, and each party hereby waives the
defense, that there is adequate remedy at law.

          11.  Entire Agreement.  This Agreement constitutes the entire
agreement between the parties with respect to the subject matter hereof and
supersedes all other prior agreements and understandings, both written and oral,
between the parties or any of them with respect to the subject matter hereof.

          12.  Further Assurances.  Each party will execute and deliver all such
further documents and instruments and take all such further action as may be
necessary to consummate the transactions contemplated hereby.

          13.  Validity.  The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect.  In
the event any court or other competent authority holds any provisions of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery 

                                      -4-
<PAGE>
 
of an amendment to this Agreement in order, as nearly as possible, to
effectuate, to the extent permitted by law, the intent of the parties hereto
with respect to such provision and the economic effects thereof. If for any
reason any such court or regulatory agency determines that Ziegler is not
permitted to acquire the full number of shares of Company Common Stock provided
in Section 1 hereof (as the same may be adjusted), it is the express intention
of the Company to allow Ziegler to acquire or to require the Company to
repurchase such lesser number of shares as may be permissible, without any
amendment or modification hereof. Each party agrees that, should any court or
other competent authority hold any provision of this Agreement or part hereof to
be null, void or unenforceable, or order any party to take any action
inconsistent herewith, or not take any action required herein, the other party
shall not be entitled to specific performance of such provision or part hereof
or to any other remedy, including but not limited to money damages, for breach
hereof or of any other provision of this Agreement or part hereof as the result
of such holding or order.

          14.  Notices.  All notices and other communications hereunder shall be
in writing and shall be deemed given (i) upon delivery if delivered personally,
or (ii) the next business day if sent by reputable overnight courier service, or
(iii) upon sending if sent by telecopy (which is confirmed), or (iv) five days
after being mailed by registered or certified mail (return receipt requested),

                        CONTINUING GUARANTY (Unlimited)
                    (For Consumer or Business Transactions)

Dated October 15, 1998

     GUARANTY.  For value received, and to induce The Ziegler Companies, Inc. of
West Bend, Wisconsin ("Lender"), to extend credit or to grant or continue other
credit accommodations to PMC International, Inc.  ("Debtor"), the undersigned
jointly and severally guarantee payment of the Obligations defined below when
due or, to the extent not prohibited by law, at the time any Debtor becomes the
subject of bankruptcy or other insolvency proceedings.  "Obligations" means all
loans, drafts, overdrafts, checks, notes, and all other debts, obligations and
liabilities of every kind and description, whether of the same or a different
nature, arising out of credit previously granted, credit contemporaneously
granted or credit granted in the future by Lender to any Debtor, to any Debtor
and another, or to another guaranteed or endorsed by any Debtor.  Obligations
include interest and charges and the amount of payments made to Lender or
another by or on behalf of any Debtor which are recovered from Lender by a
trustee, receiver, creditor or other party pursuant to applicable federal or
state law, and to the extent not prohibited by law, all costs, expenses and
attorneys' fees at any time paid or incurred before and after judgement in
endeavoring to collect all or part of any of the above, or to realize upon this
Guaranty, or any collateral securing any of the above, including those incurred
in successful defense or settlement of any counterclaim brought by Debtor or the
undersigned or incident to any action or proceeding involving Debtor or the
undersigned brought pursuant to the United States Bankruptcy Code.  Unless a
lien would be prohibited by law or would render a nontaxable account taxable,
the undersigned grant to Lender a security interest and lien in any deposit
account any of the undersigned may at any time have with Lender.  Lender may, at
any time after the occurrence of an event of default and notice and opportunity
to cure, if required by (S)425.105, Wis. Stats., set-off any amount unpaid on
the Obligations against any deposit balances any of the undersigned may at any
time have with Lender, or other money now or hereafter owed any of the
undersigned by Lender.  This Guaranty is also secured (to the extent not
prohibited by law) by all existing and future security agreements between Lender
and any of the undersigned and by any mortgage stating it secures guaranties of
any of the undersigned.  This Guaranty is valid and enforceable against the
undersigned even though any Obligation is
<PAGE>
 
invalid or unenforceable against any Debtor.

     WAIVER.  To the extent not prohibited by law the undersigned expressly
waive notice of the acceptance of this Guaranty, the creation of any present or
future Obligation, default under any Obligation, proceedings to collect from any
Debtor or anyone else, all diligence of collection and presentment, demand,
notice and protest and any right to disclosures from Lender regarding the
financial condition of any Debtor or guarantor of the Obligations or the
enforceability of the Obligations.  No claim, including a claim for
reimbursement, subrogation, contribution or indemnification which any of the
undersigned may, as a guarantor of the Obligations, have against a co-guarantor
of any of the Obligations or against any Debtor shall be enforced nor any
payment accepted until the Obligations are paid in full and no payments to or
collections by Lender are subject to any right of recovery.

     CONSENT.  With respect to any of the Obligations, Lender may from time to
time before or after revocation of this Guaranty without notice to the
undersigned and without affecting the liability of the undersigned (a)
surrender, release, impair, sell or otherwise dispose of any security or
collateral for the Obligations, (b) release or agree not to sue any guarantor or
surety, (c) fail to perfect its security interest in or realize upon any
security or collateral, (d) fail to realize upon any of the Obligations or to
proceed against any Debtor or any guarantor or surety, (e) renew or extend the
time of payment, (f) increase or decrease the rate of interest or the amount of
the Obligations, (g) accept additional security or collateral, (h) determine the
allocation and application of payments and credits and accept partial payments,
(i) determine what, if anything, may at any time be done with reference to any
security or collateral, and (j) settle or compromise the amount due or owing or
claimed to be due or owing from any Debtor, guarantor or surety, which
settlement or compromise shall not affect the undersigned's liability for the
full amount of the unpaid Obligations.  The undersigned expressly consent to and
waive notice of all of the above.  To the extent not prohibited by law, the
undersigned consent that venue for any legal proceeding relating to the
collection of this Guaranty shall be, at Lender's option, the county in which
Lender has its principal office in this state, the county in which any of the
undersigned resides or the county in which this Guaranty was executed by the
undersigned.

     PERSONS BOUND.  This Guaranty benefits Lender, its successors and assigns,
and binds the undersigned, their respective heirs, personal representatives,
successors and
<PAGE>
 
assigns.

     ENTIRE AGREEMENT.  This Guaranty is intended by the undersigned and Lender
as a final expression of this Guaranty and as a complete and exclusive statement
of its terms, there being no conditions to the full effectiveness of this
Guaranty.  This Guaranty may not be supplemented or modified except in writing.
This Guaranty includes additional provision on the reverse side.

                      GENERAL BUSINESS SECURITY AGREEMENT

                             1.  SECURITY INTEREST


Dated October 15, 1998

     The undersigned ("Debtor", whether one or more) grants The Ziegler
Companies, Inc. ("Lender") a security interest in all equipment, fixtures,
inventory (including all goods held for sale, lease or demonstration or to be
furnished under contracts of service, goods leased to others, trade-ins and
repossessions, raw materials, work in process and materials or supplies used or
consumed in Debtor's business), documents relating to inventory, general
intangibles, accounts, contract rights, chattel paper and instruments, now owned
or hereafter acquired by Debtor and all additions and accessions to, all spare
and repair parts, special tools, equipment and replacements for, all returned or
repossessed goods the sale of which gave rise to, and all proceeds and products
of the foregoing ("Collateral"), wherever located, to secure all debts,
obligations and liabilities of any Debtor to Lender arising out of credit
previously granted, credit contemporaneously granted and credit granted in the
future by Lender to any Debtor, to any Debtor and another, or to another
guaranteed or indorsed by any Debtor ("Obligations").


                            2.  DEBTOR'S WARRANTIES

     Debtor warrants that while any of the Obligations are unpaid:

     (a)  Ownership.  Debtor owns the Collateral free of all encumbrances and
security interests (except Lender's security interest)*. Chattel paper
constituting Collateral evidences a perfected security interest in the goods
covered by it, free from all other encumbrances and security interests, and no
financing statement (other than Lender's)** is on file covering the Collateral
or any of it. Debtor, acting alone, may grant a security interest in the
Collateral.

     (b)  Sale of goods or services rendered.  Each account and chattel paper
constituting Collateral as of this date arose from the performance of services
by Debtor or from a bona fide sale or lease of goods, which have been delivered
or shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.

     (c)  Enforceability.  Each account, contract right and chattel paper
constituting Collateral as of this date is genuine and enforceable against the
account debtor according to its


<PAGE>
 
terms. It and the transaction out of which it arose comply with all applicable
laws and regulations. The amount represented by Debtor to Lender as owing by
each account debtor is the amount actually owing and is not subject to setoff,
credit, allowance or adjustment, except discount for prompt payment, nor has any
account debtor returned the goods or disputed his liability.

     (d)  Due date.  There has been no default as of this date according to the
terms of any Collateral and no step has been taken to foreclose the security
interest it evidences or otherwise enforce its payment.

     (e)  Financial condition of account debtor.  As of this date Debtor has no
notice or knowledge of anything which might impair the credit standing of any
account debtor.

     (f)  Valid organization.  If a corporation, limited liability company or
partnership, Debtor is duly organized, validly existing and in good standing
under the laws of the state of organization and is authorized to do business in
Wisconsin.

     (g)  Other agreements.  Debtor is not in default under any agreement for
the payment of money.

     (h)  Authority to contract.  The execution and delivery of this Agreement
and any instruments evidencing Obligations will not violate or constitute a
breach of Debtor's articles of incorporation or organization, by-laws,
partnership agreement, operating agreement or any other agreement or restriction
to which Debtor is a party or is subject.

     (i)  Accuracy of information.  All information, certificates or statements
given to Lender pursuant to this Agreement shall be true and complete when
given.

     (j)  Addresses.  The address of the Debtor's residence, or if a
corporation, limited liability company or partnership, the address of Debtor's
place of business, or if Debtor has more than one place of business, then the
address of Debtor's chief executive office, is shown opposite Debtor's
signature. The address where the Collateral will be kept, if different from that
appearing opposite Debtor's signature, is                       . Such locations

satisfaction, Debtor is free to select the insurance agent or insurer through
which the insurance is obtained. Debtor assigns (and directs any insurer to pay)

authorizes Lender to indorse in the name of Debtor any instruments for such
proceeds or refunds and, at the option of Lender, to apply such proceeds and
refunds to any unpaid balance of the Obligations, whether or not due, and/or to
restoration of the Collateral, returning any excess to Debtor. Lender is

claims under any credit insurance financed by Lender or any insurance on the
Collateral, or cancel the same after the occurrence of an event of default.

     (c)  Maintenance of security interest.  Debtor shall pay all expenses and

statements at least annually and such other financial information respecting
Debtor at such times and in such form as Lender may request. Debtor shall keep

the Lender's interest and, upon request, deliver them to Lender.

     (i)  United State contracts.  If any accounts or contract rights
constituting Collateral arose out of contracts with the United States or any of
its departments, agencies or instrumentalities, Debtor will notify Lender and
execute writings required by Lender in order that all money due or to become due

                             7.  RIGHTS OF LENDER

     (a)  Authority to perform for Debtor.  Upon the occurrence of an event of
default or if Debtor fails to perform any of Debtor's duties set forth in this
Agreement or in any evidence of or document relating to the Obligations, Lender
is authorized, in Debtor's name or otherwise, to take any such action including
without limitation signing Debtor's name or paying any amount so required, and
the cost shall be one of the Obligations secured by this Agreement and shall be
payable by Debtor upon demand with interest from the date of payment by Lender
at the highest rate stated in any evidence of any Obligation but not in excess
of the maximum rate permitted by law.

     (b)  Charging Debtor's credit balance.  Unless a lien would be prohibited
by law or would render a nontaxable account taxable, Debtor grants Lender, as
further security for the Obligations, a security interest and lien in any
deposit account Debtor may at any time have with Lender and other money now or
hereafter owed Debtor by Lender and, in addition, agrees that Lender may, at any
time after the occurrence of an event of default, without prior notice or
demand, set-off all or any part of the unpaid balance of the Obligations against
any deposit


<PAGE>
 
balances or other money now or hereafter owed Debtor by Lender.

     (c)  Power of attorney.  Debtor irrevocably appoints any officer of Lender
as Debtor's attorney, with power after an event of default to receive, open and
dispose of all mail addressed to Debtor; to notify the Post Office authorities
to change the address for delivery of all mail addressed to Debtor to such
address as Lender may designate; and to endorse the name of Debtor upon any
instruments which may come into Lender's possession. Debtor agrees that
Obligations may be created by drafts drawn on Lender by shippers of inventory
named in section 3. Debtor authorizes Lender to honor any such draft accompanied
by invoices aggregating the amount of the draft and describing inventory to be
shipped to Debtor and to pay any such invoices not accompanied by drafts. Debtor
appoints any employee of Lender as Debtor's attorney, with full power to sign
Debtor's name on any instrument evidencing an Obligation, or any renewals or
extensions, or the amount of such drafts honored by Lender and such instruments
may be payable at fixed times or on demand, shall bear interest at the rate from
time to time fixed by Lender and Debtor agrees, upon request of Lender, to
execute any such instruments. This power of attorney to execute instruments may
be revoked by Debtor only by written notice to Lender and no such revocation
shall affect any instruments executed prior to the receipt by Lender of such
notice. All acts of such attorney are ratified and approved and such attorney is
not liable for any act or omission or for any error of judgment or mistake of
fact or law.

     (d)  Non-liability of Lender.  Lender has no duty to determine the validity
of any invoice, the authority of any shipper named in section 3 to ship goods to
Debtor or compliance with any order of Debtor. Lender has no duty to protect,
insure, collect or realize upon the Collateral or preserve rights in it against
prior parties. Debtor releases Lender from any liability for any act or omission
relating to the Obligations, the Collateral or this Agreement, except Lender's
willful misconduct.


                                  8.  DEFAULT

     Upon the occurrence of one or more of the following events of default:

     Nonperformance.  Debtor fails to pay when due any of the Obligations or to
perform, or rectify breach of, any warranty or other undertaking by Debtor in
this Agreement or in any evidence of or document relating to the Obligations;

     Inability to Perform.  Debtor, Debtor's spouse or a surety for any of the
Obligation dies, ceases to exist, becomes insolvent or the subject of bankruptcy
or insolvency proceedings;


<PAGE>
 
     Misrepresentation.  Any representation made to induce Lender to extend
credit to Debtor, under this Agreement or otherwise, is false in any material
respect when made; or

     Insecurity.  Any other event which causes Lender in good faith to deem
itself insecure; all of the Obligations shall, at the option of Lender and
without notice or demand, become immediately payable; and Lender shall have all
rights and remedies for default provided by the Wisconsin Uniform Commercial
Code, as well as any other applicable law and any evidence of or document
relating to any Obligation. With respect to such rights and remedies:

     (a)  Repossession.  Lender may take possession of Collateral without notice
or hearing, which Debtor waives;

     (b)  Assembling collateral.  Lender may require Debtor to assemble the
Collateral and to make it available to Lender at any convenient place designated
by Lender;

     (c)  Notice of disposition.  Written notice, when required by law, sent to
any address of Debtor in this Agreement at least 10 calendar days (counting the
day of sending) before the date of a proposed disposition of the Collateral is
reasonable notice;

     (d)  Expenses and application of proceeds.  Debtor shall reimburse Lender
for any expense incurred by Lender in protecting or enforcing its rights under
this Agreement before and after judgment, including, without limitation,
reasonable attorneys' fees and legal expenses of taking possession, holding,
preparing for disposition and disposing of Collateral. After deduction of such
expenses, Lender may apply the proceeds of disposition to the Obligations in
such order and amounts as it elects; and

     (e)  Waiver.  Lender may permit Debtor to remedy and default without
waiving the default so remedied, and Lender may waive any default without
waiving any other subsequent or prior default by Debtor.


                              9.  INTERPRETATION

     The validity, construction and enforcement of this Agreement are governed
by the internal laws of Wisconsin. All terms not otherwise defined have the
meanings assigned to them by the Wisconsin Uniform Commercial Code. Invalidity
of any provision of this Agreement shall not affect the validity of any other
provision. This Agreement is intended by Debtor and Lender as a final expression
of this Agreement and as a complete and exclusive statement of its terms, there
being no conditions to the enforceability of this Agreement. This Agreement may
not be supplemented or modified except in writing.

                   GENERAL BUSINESS SECURITY AGREEMENT
                         1.  SECURITY INTEREST

Dated October 15, 1998

     The undersigned ("Debtor", whether one or more) grants The Ziegler
Companies, Inc. ("Lender") a security interest in all equipment, fixtures,
inventory (including all goods held for sale, lease or demonstration or to be
furnished under contracts of service, goods leased to others, trade-ins and
repossessions, raw materials, work in process and materials or supplies used or
consumed in Debtor's business), documents relating to inventory, general
intangibles, accounts, contract rights, chattel paper and instruments, now owned
or hereafter acquired by Debtor and all additions and accessions to, all spare
and repair parts, special tools, equipment and replacements for, all returned or
repossessed goods the sale of which gave rise to, and all proceeds and products
of the foregoing ("Collateral"), wherever located, to secure all debts,
obligations and liabilities of any Debtor to Lender arising out of credit
previously granted, credit contemporaneously granted and credit granted in the
future by Lender to any Debtor, to any Debtor and another, or to another
guaranteed or indorsed by any Debtor ("Obligations").

                        2.  DEBTOR'S WARRANTIES

     Debtor warrants that while any of the Obligations are unpaid:

     (a) Ownership.  Debtor owns the Collateral free of all encumbrances and
security interests (except Lender's security interest)*.  Chattel paper
constituting Collateral evidences a perfected security interest in the goods
covered by it, free from all other encumbrances and security interests, and no
financing statement (other than Lender's)** is on file covering the Collateral
or any of it.  Debtor, acting alone, may grant a security interest in the
Collateral.

     (b) Sale of goods or services rendered.  Each account and chattel paper
constituting Collateral as of this date arose from the performance of services
by Debtor or from a bona fide sale or lease of goods, which have been delivered
or shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.
                           
     (c) Enforceability.  Each account, contract right and chattel paper
constituting Collateral as of this date is genuine and enforceable against the
account debtor according to its
<PAGE>
 
terms.  It and the transaction out of which it arose comply with all applicable
laws and regulations.  The amount represented by Debtor to Lender as owing by
each account debtor is the amount actually owing and is not subject to setoff,
credit, allowance or adjustment, except discount for prompt payment, nor has any
account debtor returned the goods or disputed his liability.

     (d) Due date.  There has been no default as of this date according to the
terms of any Collateral and no step has been taken to foreclose the security
interest it evidences or otherwise enforce its payment.

     (e) Financial condition of account debtor.  As of this date Debtor has no
notice or knowledge of anything which might impair the credit standing of any
account debtor.

     (f) Valid organization.  If a corporation, limited liability company or
partnership, Debtor is duly organized, validly existing and in good standing
under the laws of the state of organization and is authorized to do business in
Wisconsin.

     (g) Other agreements.  Debtor is not in default under any agreement for the
payment of money.

     (h) Authority to contract.  The execution and delivery of this Agreement
and any instruments evidencing Obligations will not violate or constitute a
breach of Debtor's articles of incorporation or organization, by-laws,
partnership agreement, operating agreement or any other agreement or restriction
to which Debtor is a party or is subject.

     (i) Accuracy of information.  All information, certificates or statements
given to Lender pursuant to this Agreement shall be true and complete when
given.

     (j) Addresses.  The address of the Debtor's residence, or if a corporation,
limited liability company or partnership, the address of Debtor's place of
business, or if Debtor has more than one place of business, then the address of
Debtor's chief executive office, is shown opposite Debtor's signature.  The
address where the Collateral will be kept, if different from that appearing
opposite Debtor's signature, is                .  Such locations shall not be
changed without prior written consent of Lender, but the parties intend that the
Collateral, wherever located, is covered by this Agreement.

     (k) Change of name or address.  Debtor shall immediately advise Lender in
writing of any change in name or address.
                               
     (l) Environmental laws.  (i) No substance has been, is or will be present,
used, stored, deposited, treated, recycled or disposed of on, under, in or about
any real estate now or at any time owned or occupied by Debtor ("Property")
during the period of Debtor's ownership or use of the Property in a form,
quantity
<PAGE>
 
or manner which if known to be present on, under, in or about the Property would
require clean-up, removal or some other remedial action ("Hazardous Substance")
under any federal, state or local laws, regulations, ordinances, codes or rules
("Environmental Laws"), (ii) Debtor has no knowledge, after due inquiry, of any
prior use or existence of any Hazardous Substance on the Property by any prior
owner of or person using the Property, (iii) without limiting the generality of
the foregoing, Debtor has no knowledge, after due inquiry, that the Property
contains asbestos, polychlorinated biphenyl components (PCBs) or underground
storage tanks, (iv) there are no conditions existing currently or likely to
exist during the term of this Agreement which would subject Debtor to an
damages, penalties, injunctive relief or clean-up costs in any governmental or
regulatory action or third-party claim relating to any Hazardous Substance, (v)
Debtor is not subject to any court or administrative proceeding, judgment,
decree, order or citation relating to any such substance, and (vi) Debtor in the
past has been, at the present is, and in the future will remain in compliance
with all Environmental Laws.  Debtor shall indemnify and hold harmless Lender,
its directors, officers, employees and agents from all loss, cost (including
reasonable attorneys' fees and legal expenses), liability and damage whatsoever
directly or indirectly resulting from, arising out of, or based upon (1) the
presence, use, storage, deposit, treatment, recycling or disposal, at any time,
of any Hazardous Substance on, under, in or about the Property, or the
transportation of any such substance to or from the Property, (2) the violation
or alleged violation of any Environmental Law, permit, judgment or license
relating to the presence, use, storage, deposit, treatment, recycling or
disposal of any Hazardous Substance on, under, in or about the Property, or the
transportation of any Hazardous Substance to or from Property, or (3) the
imposition of any governmental lien for the recovery of environmental clean-up
costs expended under any Environmental Law.  Debtor shall immediately notify
Lender in writing of any governmental or regulatory action or third-party claim
instituted or threatened in connection with any Hazardous Substance described
above on, in, under or about the Property.

     (m) Fixtures.  If any of the Collateral is affixed to real estate, the
legal description of the real estate set forth in each UCC Financing Statement
signed by Debtor is true and correct.

     (a) Authority to perform for Debtor.  Upon the occurrence of an event of
default or if Debtor fails to perform any of Debtor's duties set forth in this
Agreement or in any evidence of or document relating to the Obligations, Lender
is authorized, in Debtor's name or otherwise, to take any such action including
without limitation signing Debtor's name or paying any amount so required, and
the cost shall be one of the Obligations secured by this Agreement and shall be
payable by Debtor upon demand with interest from the date of payment by Lender
at the highest rate stated in any evidence of any Obligation but not in excess
of the maximum rate permitted by law.
                          
     (b) Charging Debtor's credit balance.  Unless a lien would be prohibited by
law or would render a nontaxable account taxable, Debtor grants Lender, as
further security for the Obligations, a security interest and lien in any
deposit account Debtor may at any time have with Lender and other money now or
hereafter owed Debtor by Lender and, in addition, agrees that Lender may, at any
time after the occurrence of an event of default, without prior notice or
demand, set-off all or any part of the unpaid balance of the Obligations against
any deposit
<PAGE>
 
balances or other money now or hereafter owed Debtor by Lender.

     (c) Power of attorney.  Debtor irrevocably appoints any officer of Lender
as Debtor's attorney, with power after an event of default to receive, open and
dispose of all mail addressed to Debtor; to notify the Post Office authorities
to change the address for delivery of all mail addressed to Debtor to such
address as Lender may designate; and to endorse the name of Debtor upon any
instruments which may come into Lender's possession.  Debtor agrees that
Obligations may be created by drafts drawn on Lender by shippers of inventory
named in section 3.  Debtor authorizes Lender to honor any such draft
accompanied by invoices aggregating the amount of the draft and describing
inventory to be shipped to Debtor and to pay any such invoices not accompanied
by drafts.  Debtor appoints any employee of Lender as Debtor's attorney, with
full power to sign Debtor's name on any instrument evidencing an Obligation, or
any renewals or extensions, or the amount of such drafts honored by Lender and
such instruments may be payable at fixed times or on demand, shall bear interest
at the rate from time to time fixed by Lender and Debtor agrees, upon request of
Lender, to execute any such instruments. This power of attorney to execute
instruments may be revoked by Debtor only by written notice to Lender and no
such revocation shall affect any instruments executed prior to the receipt by
Lender of such notice.  All acts of such attorney are ratified and approved and
such attorney is not liable for any act or omission or for any error of judgment
or mistake of fact or law.
                          
     (d) Non-liability of Lender.  Lender has no duty to determine the validity
of any invoice, the authority of any shipper named in section 3 to ship goods to
Debtor or compliance with any order of Debtor.  Lender has no duty to protect,
insure, collect or realize upon the Collateral or preserve rights in it against
prior parties.  Debtor releases Lender from any liability for any act or
omission relating to the Obligations, the Collateral or this Agreement, except
Lender's willful misconduct.

                                  8.  DEFAULT

     Upon the occurrence of one or more of the following events of default:

perform, or rectify breach of, any warranty or other undertaking by Debtor in
this Agreement or in any evidence of or document relating to the Obligations;

     Inability to Perform.  Debtor, Debtor's spouse or a surety for any of the
Obligation dies, ceases to exist, becomes insolvent or the subject of bankruptcy
or insolvency proceedings;
<PAGE>
 
     Misrepresentation.  Any representation made to induce Lender to extend
credit to Debtor, under this Agreement or otherwise, is false in any material
respect when made; or

     Insecurity.  Any other event which causes Lender in good faith to deem
itself insecure; all of the Obligations shall, at the option of Lender and
without notice or demand, become immediately payable; and Lender shall have all
rights and remedies for default provided by the Wisconsin Uniform Commercial
Code, as well as any other applicable law and any evidence of or document
relating to any Obligation.  With respect to such rights and remedies:

     (a) Repossession.  Lender may take possession of Collateral without notice
or hearing, which Debtor waives;

     (b) Assembling collateral.  Lender may require Debtor to assemble the
Collateral and to make it available to Lender at any convenient place designated
by Lender;

     (c) Notice of disposition.  Written notice, when required by law, sent to
any address of Debtor in this Agreement at least 10 calendar days (counting the
day of sending) before the date of a proposed disposition of the Collateral is
reasonable notice;

     (d) Expenses and application of proceeds.  Debtor shall reimburse Lender
for any expense incurred by Lender in protecting or enforcing its rights under
this Agreement before and after judgment, including, without limitation,
reasonable attorneys' fees and legal expenses of taking possession, holding,
preparing for disposition and disposing of Collateral.  After deduction of such
expenses, Lender may apply the proceeds of disposition to the Obligations in
such order and amounts as it elects; and

     (e) Waiver.  Lender may permit Debtor to remedy any default without waiving
the default so remedied, and Lender may waive any default without waiving any
other subsequent or prior default by Debtor.

                              9.  INTERPRETATION

     The validity, construction and enforcement of this Agreement are governed

                      GENERAL BUSINESS SECURITY AGREEMENT

                             1.  SECURITY INTEREST


Dated October 15, 1998

     The undersigned ("Debtor", whether one or more) grants The Ziegler
Companies, Inc. ("Lender") a security interest in all equipment, fixtures,
inventory (including all goods held for sale, lease or demonstration or to be
furnished under contracts of service, goods leased to others, trade-ins and
repossessions, raw materials, work in process and materials or supplies used or
consumed in Debtor's business), documents relating to inventory, general
intangibles, accounts, contract rights, chattel paper and instruments, now owned
or hereafter acquired by Debtor and all additions and accessions to, all spare
and repair parts, special tools, equipment and replacements for, all returned or
repossessed goods the sale of which gave rise to, and all proceeds and products
of the foregoing ("Collateral"), wherever located, to secure all debts,
obligations and liabilities of any Debtor to Lender arising out of credit
previously granted, credit contemporaneously granted and credit granted in the
future by Lender to any Debtor, to any Debtor and another, or to another
guaranteed or indorsed by any Debtor ("Obligations").


                            2.  DEBTOR'S WARRANTIES

     Debtor warrants that while any of the Obligations are unpaid:

     (a)  Ownership.  Debtor owns the Collateral free of all encumbrances and
security interests (except Lender's security interest)*. Chattel paper
constituting Collateral evidences a perfected security interest in the goods
covered by it, free from all other encumbrances and security interests, and no
financing statement (other than Lender's)** is on file covering the Collateral
or any of it. Debtor, acting alone, may grant a security interest in the
Collateral.

     (b)  Sale of goods or services rendered.  Each account and chattel paper
constituting Collateral as of this date arose from the performance of services
by Debtor or from a bona fide sale or lease of goods, which have been delivered
or shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.

     (c)  Enforceability.  Each account, contract right and chattel paper
constituting Collateral as of this date is genuine and enforceable against the
account debtor according to its


<PAGE>
 
terms. It and the transaction out of which it arose comply with all applicable
laws and regulations. The amount represented by Debtor to Lender as owing by
each account debtor is the amount actually owing and is not subject to setoff,
credit, allowance or adjustment, except discount for prompt payment, nor has any
account debtor returned the goods or disputed his liability.

     (d)  Due date.  There has been no default as of this date according to the
terms of any Collateral and no step has been taken to foreclose the security
interest it evidences or otherwise enforce its payment.

     (e)  Financial condition of account debtor.  As of this date Debtor has no
notice or knowledge of anything which might impair the credit standing of any
account debtor.

     (f)  Valid organization.  If a corporation, limited liability company or
partnership, Debtor is duly organized, validly existing and in good standing
under the laws of the state of organization and is authorized to do business in
Wisconsin.

     (g)  Other agreements.  Debtor is not in default under any agreement for
the payment of money.

     (h)  Authority to contract.  The execution and delivery of this Agreement
and any instruments evidencing Obligations will not violate or constitute a
breach of Debtor's articles of incorporation or organization, by-laws,
partnership agreement, operating agreement or any other agreement or restriction
to which Debtor is a party or is subject.

     (i)  Accuracy of information.  All information, certificates or statements
given to Lender pursuant to this Agreement shall be true and complete when
given.

     (j)  Addresses.  The address of the Debtor's residence, or if a
corporation, limited liability company or partnership, the address of Debtor's
place of business, or if Debtor has more than one place of business, then the
address of Debtor's chief executive office, is shown opposite Debtor's
signature. The address where the Collateral will be kept, if different from that
appearing opposite Debtor's signature, is . Such locations shall not be changed
without prior written consent of Lender, but the parties intend that the
Collateral, wherever located, is covered by this Agreement.

     (k)  Change of name or address.  Debtor shall immediately advise Lender in
writing of any change in name or address.

     (l)  Environmental laws.  (i) No substance has been, is or will be present,
used, stored, deposited, treated, recycled or disposed of on, under, in or about
any real estate now or at any time owned or occupied by Debtor ("Property")
during the period of Debtor's ownership or use of the Property in a form,
quantity


<PAGE>
 
or manner which if known to be present on, under, in or about the Property would
require clean-up, removal or some other remedial action ("Hazardous Substance")
under any federal, state or local laws, regulations, ordinances, codes or rules
("Environmental Laws"), (ii) Debtor has no knowledge, after due inquiry, of any
prior use or existence of any Hazardous Substance on the Property by any prior
owner of or person using the Property, (iii) without limiting the generality of
the foregoing, Debtor has no knowledge, after due inquiry, that the Property
contains asbestos, polychlorinated biphenyl components (PCBs) or underground
storage tanks, (iv) there are no conditions existing currently or likely to
exist during the term of this Agreement which would subject Debtor to an
damages, penalties, injunctive relief or clean-up costs in any governmental or
regulatory action or third-party claim relating to any Hazardous Substance, (v)
Debtor is not subject to any court or administrative proceeding, judgment,
decree, order or citation relating to any such substance, and (vi) Debtor in the
past has been, at the present is, and in the future will remain in compliance
with all Environmental Laws. Debtor shall indemnify and hold harmless Lender,
its directors, officers, employees and agents from all loss, cost (including
reasonable attorneys' fees and legal expenses), liability and damage whatsoever
directly or indirectly resulting from, arising out of, or based upon (1) the
presence, use, storage, deposit, treatment, recycling or disposal, at any time,
of any Hazardous Substance on, under, in or about the Property, or the
transportation of any such substance to or from the Property, (2) the violation
or alleged violation of any Environmental Law, permit, judgment or license
relating to the presence, use, storage, deposit, treatment, recycling or
disposal of any Hazardous Substance on, under, in or about the Property, or the
transportation of any Hazardous Substance to or from Property, or (3) the
imposition of any governmental lien for the recovery of environmental clean-up
costs expended under any Environmental Law. Debtor shall immediately notify
Lender in writing of any governmental or regulatory action or third-party claim
instituted or threatened in connection with any Hazardous Substance described
above on, in, under or about the Property.

     (m)  Fixtures.  If any of the Collateral is affixed to real estate, the
legal description of the real estate set forth in each UCC Financing Statement
signed by Debtor is true and correct.

                           5.  SALE AND COLLECTIONS

     (a)  Sale of inventory.  So long as no default exists under any of the
Obligations of this Agreement, Debtor may (a) sell inventory in the ordinary
course of Debtor's business for cash or on terms customary in the trade, at
prices not less than any minimum sale price shown on instruments evidencing
Obligations and describing inventory, or (b) lease inventory on terms customary
in the trade.

     (b)  Verification and notification.  Lender may verify Collateral in any
manner, and Debtor shall assist Lender in so doing. Upon default Lender may at
any time and Debtor shall, upon request of Lender, notify the account debtors to
make payment directly to Lender and Lender may enforce collection of, settle,
compromise, extend or renew the indebtedness of such account debtors. Until
account debtors are so notified, Debtor as agent of Lender, shall make
collections on the Collateral. Lender may at any time notify the bailee of any
Collateral of Lender's security interest.

     (c)  Deposit with Lender.  At any time Lender may require that all proceeds
of Collateral received by Debtor shall be held by Debtor upon an express trust
for Lender, shall not be commingled with any other funds or property of Debtor
and shall be turned over to Lender in precisely the form received (but endorsed
by Debtor if necessary for collection) not later than the business day following
the day of their receipt. All proceeds of Collateral received by Lender directly
or from Debtor shall be applied against the Obligations in such order and at
such times as Lender shall determine.


                            6.  DEBTOR'S COVENANTS

     (a)  Maintenance of Collateral.  Debtor shall: maintain the Collateral in
good condition and repair and not permit its value to be impaired; keep it free
from all liens, encumbrances and security interests (other than Lender's
security interest); defend it against all claims and legal proceedings by
persons other than Lender; pay and discharge when due all taxes, license fees,
levies and other charges upon it; not sell, lease or otherwise dispose of it or
permit it to become a fixture or an accession to other goods, except for sales
or leases of inventory as provided in this Agreement, not permit it to be used

it insured under policies with such provisions, for such amounts and by such
insurers as shall be satisfactory to Lender from time to time, and shall furnish
evidence of such insurance satisfactory to Lender. Subject to Lender's
satisfaction, Debtor is free to select the insurance agent or insurer through
which the insurance is obtained. Debtor assigns (and directs any insurer to pay)
to Lender the proceeds of all such insurance and any premium refund, and
authorizes Lender to indorse in the name of Debtor any instruments for such
proceeds or refunds and, at the option of Lender, to apply such proceeds and
refunds to any unpaid balance of the Obligations, whether or not due, and/or to
restoration of the Collateral, returning any excess to Debtor. Lender is
authorized, in the name of Debtor or otherwise, to make, adjust and/or settle
claims under any credit insurance financed by Lender or any insurance on the
Collateral, or cancel the same after the occurrence of an event of default.

     (c)  Maintenance of security interest.  Debtor shall pay all expenses and

assessments and government charges upon Debtor or against its properties prior
to the date on which penalties attach, unless and to the extent only that such
taxes, assessments and charges are contested in good faith and by appropriate
proceedings by Debtor.

     (e)  Records and statements.  Debtor shall furnish to Lender financial
statements at least annually and such other financial information respecting
Debtor at such times and in such form as Lender may request. Debtor shall keep
accurate and complete records respecting the Collateral in such form as Lender
may approve. At such times as Lender may require, Debtor shall furnish to Lender
a statement certified by Debtor and in such form and containing such information
as may be prescribed by Lender, showing the current status and value of the
Collateral.

     (f)  Inspection of Collateral.  At reasonable times Lender may examine the
Collateral and Debtor's records pertaining to it, wherever located, and make
copies of records. Debtor shall assist Lender in so doing.

     (g)  Service charge.  In addition to the required payments


<PAGE>
 
under the Obligations and this Agreement, Debtor shall pay Lender's then current
service charges for servicing and auditing in connection with this Agreement.

     (h)  Chattel paper.  Lender may require that chattel paper constituting

default or if Debtor fails to perform any of Debtor's duties set forth in this
Agreement or in any evidence of or document relating to the Obligations, Lender

execute any such instruments. This power of attorney to execute instruments may
be revoked by Debtor only by written notice to Lender and no such revocation
shall affect any instruments executed prior to the receipt by Lender of such
notice. All acts of such attorney are ratified and approved and such attorney is
not liable for any act or omission or for any error of judgment or mistake of
fact or law.

of any invoice, the authority of any shipper named in section 3 to ship goods to
Debtor or compliance with any order of Debtor. Lender has no duty to protect,
insure, collect or realize upon the Collateral or preserve rights in it against
prior parties. Debtor releases Lender from any liability for any act or omission
relating to the Obligations, the Collateral or this Agreement, except Lender's
willful misconduct.

without notice or demand, become immediately payable; and Lender shall have all

or hearing, which Debtor waives;

     (b)  Assembling collateral.  Lender may require Debtor to assemble the

                            2.  DEBTOR'S WARRANTIES

     Debtor warrants that while any of the Obligations are unpaid:

     (a)  Ownership.  Debtor owns the Collateral free of all encumbrances and
security interests (except Lender's security interest)*. Chattel paper
constituting Collateral evidences a perfected security interest in the goods
covered by it, free from all other encumbrances and security interests, and no
financing statement (other than Lender's)** is on file covering the Collateral
or any of it. Debtor, acting alone, may grant a security interest in the
Collateral.

     (b)  Sale of goods or services rendered.  Each account and chattel paper
constituting Collateral as of this date arose from the performance of services
by Debtor or from a bona fide sale or lease of goods, which have been delivered
or shipped to the account debtor and for which Debtor has genuine invoices,
shipping documents or receipts.

     (c)  Enforceability.  Each account, contract right and chattel paper
constituting Collateral as of this date is genuine and enforceable against the
account debtor according to its

<PAGE>
 
terms. It and the transaction out of which it arose comply with all applicable
laws and regulations. The amount represented by Debtor to Lender as owing by
each account debtor is the amount actually owing and is not subject to setoff,
credit, allowance or adjustment, except discount for prompt payment, nor has any
account debtor returned the goods or disputed his liability.

     (d)  Due date.  There has been no default as of this date according to the
terms of any Collateral and no step has been taken to foreclose the security
interest it evidences or otherwise enforce its payment.

     (e)  Financial condition of account debtor.  As of this date Debtor has no
notice or knowledge of anything which might impair the credit standing of any
account debtor.

     (f)  Valid organization.  If a corporation, limited liability company or
partnership, Debtor is duly organized, validly existing and in good standing
under the laws of the state of organization and is authorized to do business in
Wisconsin.

     (g)  Other agreements.  Debtor is not in default under any agreement for
the payment of money.

     (h)  Authority to contract.  The execution and delivery of this Agreement
and any instruments evidencing Obligations will not violate or constitute a
breach of Debtor's articles of incorporation or organization, by-laws,
partnership agreement, operating agreement or any other agreement or restriction
to which Debtor is a party or is subject.

     (i)  Accuracy of information.  All information, certificates or statements
given to Lender pursuant to this Agreement shall be true and complete when
given.

     (j)  Addresses.  The address of the Debtor's residence, or if a
corporation, limited liability company or partnership, the address of Debtor's
place of business, or if Debtor has more than one place of business, then the
address of Debtor's chief executive office, is shown opposite Debtor's
signature. The address where the Collateral will be kept, if different from that
appearing opposite Debtor's signature, is               . Such locations shall
not be changed without prior written consent of Lender, but the parties intend
that the Collateral, wherever located, is covered by this Agreement.

     (k)  Change of name or address.  Debtor shall immediately advise Lender in
writing of any change in name or address.

     (l)  Environmental laws.  (i) No substance has been, is or will be present,
used, stored, deposited, treated, recycled or disposed of on, under, in or about
any real estate now or at any time owned or occupied by Debtor ("Property")
during the period of Debtor's ownership or use of the Property in a form,
quantity

<PAGE>
 
or manner which if known to be present on, under, in or about the Property would
require clean-up, removal or some other remedial action ("Hazardous Substance")
under any federal, state or local laws, regulations, ordinances, codes or rules
("Environmental Laws"), (ii) Debtor has no knowledge, after due inquiry, of any
prior use or existence of any Hazardous Substance on the Property by any prior
owner of or person using the Property, (iii) without limiting the generality of
the foregoing, Debtor has no knowledge, after due inquiry, that the Property
contains asbestos, polychlorinated biphenyl components (PCBs) or underground
storage tanks, (iv) there are no conditions existing currently or likely to
exist during the term of this Agreement which would subject Debtor to an
damages, penalties, injunctive relief or clean-up costs in any governmental or
regulatory action or third-party claim relating to any Hazardous Substance, (v)
Debtor is not subject to any court or administrative proceeding, judgment,
decree, order or citation relating to any such substance, and (vi) Debtor in the
past has been, at the present is, and in the future will remain in compliance
with all Environmental Laws. Debtor shall indemnify and hold harmless Lender,
its directors, officers, employees and agents from all loss, cost (including
reasonable attorneys' fees and legal expenses), liability and damage whatsoever
directly or indirectly resulting from, arising out of, or based upon (1) the
presence, use, storage, deposit, treatment, recycling or disposal, at any time,
of any Hazardous Substance on, under, in or about the Property, or the
transportation of any such substance to or from the Property, (2) the violation
or alleged violation of any Environmental Law, permit, judgment or license
relating to the presence, use, storage, deposit, treatment, recycling or
disposal of any Hazardous Substance on, under, in or about the Property, or the
transportation of any Hazardous Substance to or from Property, or (3) the
imposition of any governmental lien for the recovery of environmental clean-up
costs expended under any Environmental Law. Debtor shall immediately notify
Lender in writing of any governmental or regulatory action or third-party claim
instituted or threatened in connection with any Hazardous Substance described
above on, in, under or about the Property.

     (m)  Fixtures.  If any of the Collateral is affixed to real estate, the
legal description of the real estate set forth in each UCC Financing Statement
signed by Debtor is true and correct.

                                 3.  SHIPPERS

make payment directly to Lender and Lender may enforce collection of, settle,
compromise, extend or renew the indebtedness of such account debtors. Until
account debtors are so notified, Debtor as agent of Lender, shall make
collections on the Collateral. Lender may at any time notify the bailee of any
Collateral of Lender's security interest.

     (c)  Deposit with Lender.  At any time Lender may require that all proceeds
of Collateral received by Debtor shall be held by Debtor upon an express trust
for Lender, shall not be commingled with any other funds or property of Debtor
and shall be turned over to Lender in precisely the form received (but endorsed
by Debtor if necessary for collection) not later than the business day following
the day of their receipt. All proceeds of Collateral received by Lender directly
or from Debtor shall be applied against the Obligations in such order and at
such times as Lender shall determine.

                            6.  DEBTOR'S COVENANTS

satisfaction, Debtor is free to select the insurance agent or insurer through
which the insurance is obtained. Debtor assigns (and directs any insurer to pay)
to Lender the proceeds of all such insurance and any premium refund, and
authorizes Lender to indorse in the name of Debtor any instruments for such
proceeds or refunds and, at the option of Lender, to apply such proceeds and
refunds to any unpaid balance of the Obligations, whether or not due, and/or to
restoration of the Collateral, returning any excess to Debtor. Lender is

statements at least annually and such other financial information respecting
Debtor at such times and in such form as Lender may request. Debtor shall keep

                             7.  RIGHTS OF LENDER

     (a)  Authority to perform for Debtor.  Upon the occurrence of an event of
default or if Debtor fails to perform any of Debtor's duties set forth in this
Agreement or in any evidence of or document relating to the Obligations, Lender
is authorized, in Debtor's name or otherwise, to take any such action including
without limitation signing Debtor's name or paying any amount so required, and
the cost shall be one of the Obligations secured by this Agreement and shall be
payable by Debtor upon demand with interest from the date of payment by Lender
at the highest rate stated in any evidence of any Obligation but not in excess
of the maximum rate permitted by law.

     (b)  Charging Debtor's credit balance.  Unless a lien would be prohibited
by law or would render a nontaxable account taxable, Debtor grants Lender, as
further security for the Obligations, a security interest and lien in any
deposit account Debtor may at any time have with Lender and other money now or
hereafter owed Debtor by Lender and, in addition, agrees that Lender may, at any
time after the occurrence of an event of default, without prior notice or
demand, set-off all or any part of the unpaid balance of the Obligations against
any deposit

<PAGE>
 
balances or other money now or hereafter owed Debtor by Lender.

     (c)  Power of attorney.  Debtor irrevocably appoints any officer of Lender
as Debtor's attorney, with power after an event of default to receive, open and
dispose of all mail addressed to Debtor; to notify the Post Office authorities
to change the address for delivery of all mail addressed to Debtor to such
address as Lender may designate; and to endorse the name of Debtor upon any
instruments which may come into Lender's possession. Debtor agrees that
Obligations may be created by drafts drawn on Lender by shippers of inventory
named in section 3. Debtor authorizes Lender to honor any such draft accompanied
by invoices aggregating the amount of the draft and describing inventory to be
shipped to Debtor and to pay any such invoices not accompanied by drafts. Debtor
appoints any employee of Lender as Debtor's attorney, with full power to sign
Debtor's name on any instrument evidencing an Obligation, or any renewals or
extensions, or the amount of such drafts honored by Lender and such instruments
may be payable at fixed times or on demand, shall bear interest at the rate from
time to time fixed by Lender and Debtor agrees, upon request of Lender, to
execute any such instruments. This power of attorney to execute instruments may
be revoked by Debtor only by written notice to Lender and no such revocation
shall affect any instruments executed prior to the receipt by Lender of such
notice. All acts of such attorney are ratified and approved and such attorney is
not liable for any act or omission or for any error of judgment or mistake of
fact or law.

     (d)  Non-liability of Lender.  Lender has no duty to determine the validity
of any invoice, the authority of any shipper named in section 3 to ship goods to
Debtor or compliance with any order of Debtor. Lender has no duty to protect,
insure, collect or realize upon the Collateral or preserve rights in it against
prior parties. Debtor releases Lender from any liability for any act or omission
relating to the Obligations, the Collateral or this Agreement, except Lender's
willful misconduct.

                                  8.  DEFAULT

     Upon the occurrence of one or more of the following events of default:

     Nonperformance.  Debtor fails to pay when due any of the Obligations or to
perform, or rectify breach of, any warranty or other undertaking by Debtor in
this Agreement or in any evidence of or document relating to the Obligations;

     Inability to Perform.  Debtor, Debtor's spouse or a surety for any of the
Obligation dies, ceases to exist, becomes insolvent or the subject of bankruptcy
or insolvency proceedings;

<PAGE>
 
     Misrepresentation.  Any representation made to induce Lender to extend
credit to Debtor, under this Agreement or otherwise, is false in any material
respect when made; or

     Insecurity.  Any other event which causes Lender in good faith to deem
itself insecure; all of the Obligations shall, at the option of Lender and
without notice or demand, become immediately payable; and Lender shall have all
rights and remedies for default provided by the Wisconsin Uniform Commercial
Code, as well as any other applicable law and any evidence of or document
relating to any Obligation. With respect to such rights and remedies:

     (a)  Repossession.  Lender may take possession of Collateral without notice
or hearing, which Debtor waives;

     (b)  Assembling collateral.  Lender may require Debtor to assemble the
Collateral and to make it available to Lender at any convenient place designated
by Lender;

     (c)  Notice of disposition.  Written notice, when required by law, sent to
any address of Debtor in this Agreement at least 10 calendar days (counting the
day of sending) before the date of a proposed disposition of the Collateral is
reasonable notice;

     (d)  Expenses and application of proceeds.  Debtor shall reimburse Lender
for any expense incurred by Lender in protecting or enforcing its rights under
this Agreement before and after judgment, including, without limitation,
reasonable attorneys' fees and legal expenses of taking possession, holding,
preparing for disposition and disposing of Collateral. After deduction of such
expenses, Lender may apply the proceeds of disposition to the Obligations in
such order and amounts as it elects; and

     (e)  Waiver.  Lender may permit Debtor to remedy any default without
waiving the default so remedied, and Lender may waive any default without
waiving any other subsequent or prior default by Debtor.

                              9.  INTERPRETATION

          ----------------------------------------------------------------
Expenses.
- -------- 

          (a) As compensation for all services provided by Employee, the Company
will pay Employee a base salary of $240,000 per year ("Base Salary"), prorated
for any portion of a year, payable in arrears in the same manner as the Company
customarily pays the salaries of its employees or as the parties hereto may
otherwise agree.

          (b) Employee will be eligible for performance-based increases to this
Base Salary as established by the Company in its discretion.

          (c) In addition to Base Salary and Performance Salary, the Company
will provide Employee with the benefits of such insurance plans, hospitalization
plans, pension or profit sharing plans and other employee fringe benefit plans
as are customarily provided to employees of the 

                                       3
<PAGE>
 
Company and for which Employee is eligible under the terms of such plans.
Nothing in this Agreement requires the Company to adopt or maintain any such
plan. During Employee's employment by the Company, Employee will be entitled to
four weeks of paid vacation, which will be reasonably used so as to avoid
disruption of the Company's operations.

          (d) Except as set forth herein, nothing in this Agreement requires the
Company to establish an equity incentive program or confer on Employee any right
to receive any stock option or other equity incentive not awarded on or before
the date hereof.

          (e) The Company will reimburse Employee for all reasonable out-of-
pocket expenses incurred by Employee at the request of the Company in the
performance of his duties under this Agreement and such other expenses as may be
approved by the Company in accordance with the Company's reimbursement policies
as in effect from time to time, in each case upon presentation to the Company of
an itemized accounting of such expenses with reasonable supporting data.

     4.   Term.  Subject to Section 9(j), this Agreement will become effective
          ----                                                                
on November 3, 1998 and, unless earlier terminated in accordance with Section 5,
will expire one year from such effective date (the "Expiration Date"). If this
Agreement expires or is terminated, this Agreement will forthwith become void
and there will be no liability or obligation on the part of the parties hereto,
except as otherwise provided herein and except that the provisions of this
Section 4 and Sections 5, 6, 7, 8 and 9 will remain in full force and effect and
survive any termination or expiration of this Agreement.

     5.   Termination.
          ----------- 

          (a) In the event of the death of the Employee, except with respect to
any benefits that have accrued and have not been paid to the Employee under this
Agreement, the provisions of this Agreement will terminate immediately.
However, the Employee's estate will have the right to receive compensation due
to the Employee as of and to the date of his death and, furthermore, to receive
an additional amount equal to one-twelfth (1/12) of the employee's annual
compensation as specified in Section 3(a).

          (b) If the Employee is prevented by illness, accident, or other
incapacity from properly performing his duties under this Agreement (and, if
required by the Company, upon the furnishing of evidence reasonably satisfactory
to the Company of such disability), the Company will, during the continuance of
his disability, but only for the remaining term of this Agreement, pay the
Employee his compensation payable under the provisions of Section 3 (less the
amount of any benefits paid to the Employee under any disability insurance
provided by the Company) and continue to provide the Employee all other benefits
provided under this Agreement.  As used herein, the term "disability" means the
complete and total inability of the Employee, due to illness, physical or
comprehensive mental impairment to substantially perform all of his duties as
described in this Agreement for a consecutive period of 30 days or more.

                                       4
<PAGE>
 
          (c) The Company may terminate this Agreement at any time, with or
without cause, by giving written notice of termination to Employee.  If Employee
is terminated by the Company, then the Employee retains the right to receive and
the Company shall pay Base Salary, Performance Salary, and benefits through the
Expiration Date; provided, however, that Employee's right to receive and the
Company's obligation to pay Base Salary, Performance Salary and benefits for the
remaining term of this Agreement shall immediately terminate if the Employee
Participates In or obtains employment with a Competitive Advisory Business.

          (d) The Employee may terminate this Agreement at any time, for any
reason, by giving written notice of termination to the Company.  If Employee
terminates the Agreement, then the Employee releases all rights to receive Base
Salary, Performance Salary, and benefits, other than those which have accrued
prior to the date on which the Employee terminated the Agreement or those which
are required by law and agrees to provide a written release of any age or other
discrimination claims as part of the termination notice.

          (e) Upon the termination of this Agreement, for any reason whatsoever,
until December 1, 1999, Employee shall not, directly or indirectly, solicit the
business of Ernst & Young LLP, or act in any other way reasonably intended to
interfere with the relationship between Ernst & Young LLP and the Company.

     6.   Non-Disclosure of Information.
          ----------------------------- 

          (a) Except as specifically permitted by the Company in writing or as
required for Employee to perform his services and duties hereunder, during the
period beginning on the date of this Agreement and ending on the date that is
two years after the expiration or termination of this Agreement (the "Non-
Disclosure Period"), Employee will not disclose any Proprietary Information to
any person or entity for any purpose or use.  This Section 6 is not intended to
prevent Employee from obtaining employment in the Company's industry and,
accordingly, the disclosure of the fact of Employee's employment or engagement
in the Company's industry or the use of Employee's industry knowledge  or of
information or knowledge which has passed into the public domain other than
through acts or omissions attributable to Employee, shall not be deemed the
disclosure of Proprietary Information.

                                       5
<PAGE>
 
          (b) Upon the termination or expiration of this Agreement, Employee
will deliver to the Company or with the Company's permission cause to be
destroyed all notes, letters, prints, records, forms, contracts, studies,
reports, appraisals, financial data, lists of names or other customer data, and
any other articles or papers, software, computer tapes and materials that have
come into his possession by reason of his engagement by the Company, whether or
not prepared by him, and he will not retain any memoranda, summaries, or copies
of any of those items.

          (c) Employee acknowledges that Proprietary Information of the Company
is a unique and valuable asset of the Company, the loss or unauthorized
disclosure or use of which would cause the Company irreparable harm.

     7.   Inventions.
          ---------- 

          (a) Employee hereby assigns and agrees to assign to the Company, or to
any person or entity designated by the Company, without royalty or other
consideration to Employee therefor other than the compensation set forth in this
Agreement, all of his right, title and interest in and to all (i) Inventions,
(ii) applications for United States of America and foreign letters patent, (iii)
United States of America and foreign letters patent granted upon Inventions, and
(iv) material related to any of the foregoing subject to copyright.  Employee
further acknowledges that all copyrightable materials developed or produced by
Employee within the scope of his engagement by the Company constitute works made
for hire.  Notwithstanding anything to the contrary in this Section 7(a),
Employee's obligations under this Section 7(a) will only apply to the extent the
items set forth in clauses (i) through (iv) hereof relate to or arise out of
Employee's employment by the Company.

          (b) Employee will communicate promptly and disclose to the Company, in
such form as the Company may reasonably request, all information, details and
data pertaining to any of the items described in Section 7(a).

          (c) At the request of the Company, Employee will do all acts necessary
or appropriate to secure for the Company the full benefits of each item
described in Section 7(a), and otherwise to carry into full force and effect the
assignment contained in Section 7(a).  Such acts may include giving testimony in
support of Employee's inventorship and promptly executing and delivering to the
Company such papers, instruments and documents, without expense to Employee, as
may be appropriate in the Company's opinion to apply for, secure, maintain,
reissue, extend or defend the Company's worldwide rights in any item described
in Section 7(a).

     8.   Injunctive Relief.  Employee acknowledges that the breach or
          -----------------                                           
threatened breach by Employee of any of the provisions of Section 5(e), 6 or 7
would cause the Company irreparable harm.  Upon the breach or threatened breach
of any provision of Section 5(e), 6 or 7, the Company will be entitled to any
injunction, without bond, restraining Employee from committing such breach. This
right will not be construed to limit the Company's ability to obtain any other
remedies available to it for such breach or threatened breach, including the
recovery of damages.

remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.  No failure or delay on the part of any party
hereto in the exercise of any right hereunder will impair such right or be
construed to be a waiver of, or acquiescence in, any breach of any
representation, warranty or agreement herein, nor will any single or partial
exercise of any such right preclude other or further exercise thereof or of any
other right.

          (b) Governing Law.  This Agreement, its interpretation, and the legal
              -------------

invalid, illegal or unenforceable in any jurisdiction by any court of competent
jurisdiction, then (i) such invalidity, illegality or unenforceability will not
affect such provision with respect to any other jurisdiction, (ii) such
invalidity, illegality or unenforceability will not affect any other provision
of this Agreement with respect to such jurisdiction, and (iii) such court may
modify such provision of this Agreement with respect to such jurisdiction, and
such provision will thereafter be enforced in its modified form in such
jurisdiction if the parties hereto agree that such modification will achieve, to
the extent possible, the economic, business and other purposes of such invalid,
illegal or unenforceable provision.

     This Shareholder Tender Agreement (the "Agreement") is made and entered
into as of the _____ day of _______, 1998, by and between The Ziegler Companies,
Inc., a Wisconsin corporation ("Ziegler"), and ______________________________
("Shareholder"), a shareholder of PMC International, Inc., a Colorado

     WHEREAS, Ziegler has entered into negotiations with the Company and,
subject to entering into a definitive merger agreement, proposes to offer to
purchase all of the outstanding shares of the Company's common stock, par value
$.01 per share (the "Common Stock") at a price of at least $__________ per share
in a tender offer and proceed with a subsequent merger; and

     WHEREAS, Ziegler desires the tender of Shareholder's shares of Common Stock
in the tender offer, and Shareholder is willing to tender [his/her/its] shares
of Common Stock in the tender offer at a price of at least $__________ per
share;

     NOW, THEREFORE, in consideration of inducing Ziegler to proceed with
negotiating a definitive merger agreement and a tender offer and the premises
and the mutual covenants and agreements set forth herein and for other
consideration, the validity and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

     1.   Shareholder Tender. Shareholder agrees to tender as promptly as
practicable after Ziegler commences (within the meaning of Rule 14d-2 under the
Securities Exchange Act of 1934, as amended) an offer to purchase all
outstanding shares of Common Stock at a price of at least $__________ per share
(the "Offer"), to Ziegler or an affiliate all shares of Common Stock which are
outstanding and beneficially owned by Shareholder as of this date (_______
shares) and all shares subsequently acquired by Shareholder, pursuant to and in
accordance with the terms and conditions of the Offer and to not withdraw such
shares.

     2.   Termination. If any of the conditions set forth in the Offer have not
been satisfied or waived by Ziegler by December 31, 1998 (or earlier, if
required by law), this Agreement shall terminate and Ziegler shall return all
shares of Common Stock, if any, tendered by Shareholder.

     3.   Effect of Termination. In the event this Agreement is terminated
pursuant to Section 2 hereof, this Agreement shall become void and have no
effect, without any liability on the part of any party or its directors,
officers or shareholders.

     4.   Legality. The parties stipulate and agree that the provisions
contained herein are reasonable and are not known or believed to be in violation
of any federal or state law or regulation. In the event a court of competent
jurisdiction finds any provision contained herein to be illegal or
unenforceable, such court may modify such provision to make it valid and
enforceable. Such modification shall not affect the remainder of this Agreement,
which shall continue at all times to be valid and enforceable.

     5.   Entire Agreement. This Agreement contains the entire understanding of
the parties relative to the matters contained herein and therein, and may be
assigned to a wholly owned subsidiary of Ziegler, at Ziegler's option.

     6.   Governing Law. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of Wisconsin.

     7.   Counterparts. This Agreement may be executed in two counterparts,
manually or in facsimile, each of which shall be deemed to be an original, but
both of which, taken together, shall constitute one and the same instrument.

     8.   Amendments; Waiver. This Agreement may be amended by the parties
hereto and the terms and conditions hereof may be waived only by an instrument
in writing signed on behalf of each of the parties hereto, or, in the case of a
waiver, by an instrument signed on behalf of the party waiving compliance.
<PAGE>
 
     9.   No Liability. This Agreement does not constitute and will not give
rise to any legally binding obligation on the part of Ziegler or its affiliates
to enter into a definitive merger agreement or proceed with the Offer, and no
past or future action, course of conduct, or failure to act relating to the
negotiation of the terms of any definitive merger agreement, will give rise to
or serve as a basis for any obligation or other liability on the part of Ziegler
or its affiliates.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.

     WHEREAS, the Company and the Former ADAM Shareholders entered into that
certain Stock Purchase Agreement by and among the Company, the Former ADAM
Shareholders and ADAM Investment Services, Inc., dated as of July 25, 1997 (the
"Stock Purchase Agreement");

     WHEREAS, the Initial Purchase Price Adjustment amount has been finally

of $1,822,311 (the "Amount") plus interest from the Closing Date, as defined in
the Stock Purchase Agreement (the "Closing Date") at an annual rate of 8.5% and
12.0% beginning on November 6, 1998, until full and complete payment is made;
and

     WHEREAS, the Company and the Former ADAM Shareholders desire to amend (in
accordance with Section 10.1 of the Stock Purchase Agreement) the payment terms
of the Initial Purchase Price Adjustment.

     NOW, THEREFORE, for and in consideration of the mutual covenants contained
herein, the parties hereto agree as follows:

     1.  Definitions.    Terms not otherwise defined herein shall have the
meanings assigned to them in the Stock Purchase Agreement.
<PAGE>
 
     2.  Amendments.  (a) Section 2.3(e) of the Stock Purchase Agreement is
hereby deleted in its entirety and the following inserted in its place.

         "(e) If any amount of the Initial Purchase Price Adjustment is not
          made when such amount is due and owing hereunder, Buyer (the Company)
          shall pay to the Former ADAM Shareholders interest on such unpaid
          amount until paid at a rate of 12.0%."

     (b) Notwithstanding anything in the Stock Purchase Agreement to the
contrary, the Initial Purchase Price Adjustment shall be paid as follows:

          (i) $500,000 of the Initial Purchase Price Adjustment shall be paid on
          November 6, 1998 to the account listed hereto as Exhibit A;

          (ii) $500,000 of the Initial Purchase Price Adjustment shall be paid
          on the earlier of (A) the next business day after the consummation of
          the Offer (as such term is defined in that certain Agreement and Plan
          of Merger by and among the Company, The Ziegler Companies, Inc. and
          ZACQ Corp. (the "Merger Agreement") ), or (B) January 6, 1999 to the
          account listed hereto as Exhibit A; and

          (iii) the remaining balance of principal and interest of the Initial
          Purchase Price Adjustment shall be paid to the account listed hereto
          as Exhibit A on the earlier of (A) the Effective Time of the Merger
          (as such terms are defined in the Merger Agreement) or (B) March 31,
          1999.

     (c) Notwithstanding anything in the Stock Purchase Agreement to the
contrary, interest shall be paid on the Amount, which interest shall include:

                                       2

Amount from the Closing Date up through and including November 6, 1998 and (ii)
simple interest at a rate of 12.0% for the remainder of the Amount until paid in
full.

     3.   Full Force and Effect.  Except as explicitly modified herein, the
Stock Purchase Agreement shall remain in full force and effect.

     4.   Representation.  John W. Burgin represents that he is the Shareholder

Company on October 14, 1998 and he has the authority to enter into this binding
Agreement pursuant to Section 10.1 of the Stock Purchase Agreement on behalf of
the Former ADAM Shareholders.

     5.   Restoration of Rights.  In the event the Company does not make the
payments required by paragraph 2(b) hereof and does not cure within five (5)
business days of receiving notice from Shareholders' Representative, such
nonpayment shall constitute a default hereunder, and this First Amendment to the
Stock Purchase Agreement shall become null and void and the rights of the Former
ADAM Shareholders under the Stock Purchase Agreement may be enforced to the full
extent permitted, including but not limited to, the payments required under
Section 2.2 and the interest payments and penalties required under Section
2.3(e).
