                                   THE MERGER

                  1.1. THE MERGER. (a) Upon the terms and subject to the

<PAGE>   7

                  1.3. BY-LAWS. Subject to Section 6.9(a) hereof, the By-Laws of
the Purchaser in effect immediately prior to the Effective Time shall be the
By-Laws of the Surviving Corporation until thereafter amended, altered or
repealed as provided therein and by law.

                  1.4. DIRECTORS AND OFFICERS. The directors and officers of the
Purchaser immediately prior to the Effective Time shall be the directors and

accordance with the Certificate of Incorporation and By-Laws of the Surviving
Corporation.

                  1.5. EFFECTIVE TIME. The Merger shall become effective at the
time when a properly executed certificate of merger (the "Certificate of

                                   ARTICLE II

                              CONVERSION OF SHARES

                  2.1. COMPANY COMMON STOCK. (a) Each share (a "Share") of
common stock, par value $0.01 per share (the "Common Stock"), of the Company
issued and outstanding immediately prior to the Effective Time (except for
Shares then owned beneficially or of record by the Company, the Parent, the
Purchaser or any of the other Parent Subsidiaries or the Company Subsidiaries,
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive 0.23739 (the "Exchange Ratio")
of a share of common stock, no par value, of the Parent ("Parent Common Stock")
(such fractional share, the "Merger Consideration").

                  (b) Each Share issued and outstanding immediately prior to the
Effective Time which is then owned beneficially or of record by the Company, the
Parent, the Purchaser or any of the other Parent Subsidiaries or the Company
Subsidiaries, shall, by virtue of the Merger and without any action on the part
of the holder thereof, be canceled and retired and cease to exist, without any
conversion thereof.

                  (c) Each Share issued and held in the Company's treasury
immediately prior to the Effective Time shall, by virtue of the Merger, be
canceled and retired and cease to exist, without any conversion thereof.

                  (d) At the Effective Time the holders of certificates
representing Shares shall cease to have any rights as stockholders of the
Company, except for the right to



                                       2
<PAGE>   8



receive the Merger Consideration and for such rights, if any, as they may have
pursuant to the DGCL.

                  2.2. FRACTIONAL INTERESTS. No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and such fractional interests will not entitle the
owner thereof to any rights as a shareholder of the Parent. In lieu of a
fractional interest in a share of Parent Common Stock, each holder of Shares
exchanged pursuant to Section 2.1 who would otherwise have been entitled to
receive a fraction of a share of Parent Common Stock shall receive cash (without
interest) in an amount equal to the product of such fractional interest
multiplied by the Parent Common Stock Value.

                  2.3. ANTI-DILUTION PROVISIONS. The Exchange Ratio shall be
adjusted appropriately to reflect any stock dividends, splits, recapitalizations
or other similar transactions with respect to the Shares and the shares of
Parent Common Stock where the record date occurs prior to the Effective Time.

                  2.4. PURCHASER COMMON STOCK. Each share of common stock, par
value $0.01 per share ("Purchaser Common Stock"), of the Purchaser issued and
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into and exchangeable for one fully paid and non-assessable share of common
stock, par value $0.01 per share ("Surviving Corporation Common Stock"), of the
Surviving Corporation. From and after the Effective Time, each outstanding
certificate theretofore representing shares of Purchaser Common Stock shall be
deemed for all purposes to evidence ownership of and to represent the same
number of shares of Surviving Corporation Common Stock.

                  2.5. EXCHANGE OF SHARES. (a) Prior to the Effective Time, the
Parent shall deposit in trust with Chase Mellon Shareholder Services or another
exchange agent designated by the Purchaser and reasonably satisfactory to the
Company (the "Exchange Agent"), shares of Parent Common Stock in an amount
sufficient to pay the Merger Consideration payable pursuant to Section 2.1(a)
plus sufficient cash to make the payments required under Section 2.2 (such
amount being hereinafter referred to as the "Exchange Fund"). The Exchange Agent
shall, pursuant to irrevocable instructions, issue the shares of Parent Common
Stock out of the stock portion of the Exchange Fund and make the payments
provided for in Section 2.2 of this Agreement out of the cash portion of the
Exchange Fund. The Exchange Agent shall invest the cash portion of the Exchange
Fund as the Parent directs, in direct obligations of the United States of
America, obligations for which the full faith and credit of the United States of
America is pledged to provide for the payment of all principal and interest,
commercial paper obligations receiving the highest rating from either Moody's
Investors Services, Inc. or Standard & Poor's Corpora tion, or certificates of
deposit, bank repurchase agreements or banker's acceptances of commercial banks
with capital exceeding $10,000,000,000. The Exchange Fund shall not be used for
any other purpose except as provided in this Agreement.

                  (b) Promptly after the Effective Time, the Surviving
Corporation shall cause the Exchange Agent to mail to each record holder (other
than the Company, the Parent, the Purchaser or any of the other Parent
Subsidiaries or the Company Subsidiaries) as of the Effective Time of an
outstanding certificate or certificates which immediately prior to the Effective
Time represented Shares (the "Certificates") a form 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
Certificates for payment therefor. Upon surrender to the Exchange Agent of a
Certificate, together with such letter of transmittal duly executed, the holder
of such Certificate shall be entitled to receive in exchange therefor the number
of shares of Parent Common Stock equal to the product of the number of Shares
represented by such Certificate and the Exchange Ratio plus cash in lieu of
fractional shares, less any applicable withholding tax, and such Certificate
shall forthwith be canceled. No interest shall be paid or accrued on the shares
of Parent Common Stock or 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 Exchange Agent and the Surviving
Corporation that such tax has been paid or is not applicable. Until surrendered
in accordance with the provisions of this Section 2.5, each Certificate (other
than Certificates representing Shares owned benefi cially or of record by the
Company, the Parent, the Purchaser or any of the other Parent Subsidiaries or
Company Subsidiaries) shall represent for all purposes the right to receive the
number of shares of Parent Common Stock equal to the product of the number of
Shares evidenced by such Certificate and the Exchange Ratio plus cash in lieu of
fractional shares, without any interest thereon.

                  (c) If any Certificate is lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Exchange Agent, the
Surviving Corporation or the Parent, the posting by such person of a bond in
such reasonable amount as such entity may direct as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
shall issue, in exchange for such lost, stolen or destroyed Certificate, the
applicable portion of the Merger Consideration pursuant to this Agreement.

                  (d) After the Effective Time there shall be no transfers on
the stock transfer books of the Surviving Corporation of the Shares which were
outstanding immedi ately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation, they shall be
canceled and exchanged for the applicable portion of the Merger Consideration
pursuant to this Agreement.

                  (e) Any portion of the Exchange Fund which remains unclaimed
by the stockholders of the Company for one year after the Effective Time
(including any interest 



                                       4
<PAGE>   10

received with respect thereto) shall be repaid to the Surviving Corporation,
upon demand. Any stockholders of the Company who have not theretofore complied
with Section 2.5(b) shall thereafter look only to the Surviving Corporation
(subject to abandoned property, escheat or other similar laws) for payment of
their proportionate claim for the Merger Consideration plus cash in lieu of
fractional shares, without any interest thereon, but shall have no greater
rights against the Surviving Corporation than may be accorded to general
creditors of the Surviving Corporation under Delaware law.

                  2.6. EMPLOYEE STOCK OPTIONS. The Company's Employee Incentive
Compensation Plan (the "Company Option Plan") and all options to acquire Shares
granted pursuant to the Company Option Plan that are issued and outstanding
immediately before the Effective Time (collectively, the "Options"), shall be
assumed by the Parent on the Effective Time and shall continue in effect, as an
option plan of Parent and as options issued by Parent, respectively, in
accordance with the terms and conditions by which they are governed immediately
before the Effective Time (and each Option that becomes fully vested and
exercisable as a result of the Merger shall continue as a fully vested and
exercisable option of Parent), subject to the adjustments set forth in the next
sentence. On the Effective Time, each Option shall, by virtue of the Merger and
without any action on the part of the holder thereof, be automatically adjusted
to provide that (a) the number and type of shares issuable upon exercise of such
Option shall be that number of shares of Parent Common Stock (rounded off to the
nearest whole number of shares) equal to the number of Shares issuable upon
exercise of such Option immediately before the Effective Time, multiplied by the
Exchange Ratio, and (b) the exercise price per share of Parent Common Stock
under such Option shall be that amount (rounded up to the nearest whole cent)
equal to the exercise price per Share under such Option immediately before the
Effective Time, divided by the Exchange Ratio.


                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

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

                  3.1. ORGANIZATION. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. Each of the Company Subsidiaries which is a corporation is duly
organized, and each of the Company Subsidiaries which is a limited partnership
is duly formed, and each of the Company Subsidiaries is validly existing and in
good standing, in each case under the laws of the jurisdictions of its
incorporation or formation, as the case may be. Each of the Company and the
Company Subsidiaries has all requisite power and authority to own, lease and
operate its properties and to conduct its business as now being conducted.
Except as set forth in Section 3.1 of the disclosure letter delivered by the
Company to the Parent and Purchaser prior to the execution of this Agreement
(the "Company Disclosure Letter"), 


                                       5
<PAGE>   11

each of the Company and the Company Subsidiaries is duly qualified or licensed
and in good standing to do business 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 nec essary, except where the failure to be so qualified
or licensed and in good standing would not have a material adverse effect on the
business or financial condition of the Company and the Company Subsidiaries
taken as a whole. Each of the Company Subsidiaries is listed in Section 3.1 of
the Company Disclosure Letter, and except as and to the extent set forth
therein, the Company owns beneficially and of record directly or indirectly all
of the issued and outstanding capital stock or limited partnership interests, as
the case may be, of each of the Company Subsidiaries, free and clear of any
liens, claims, charges, mortgages or other encumbrances (collectively, "Liens").
Except as set forth in Section 3.1 of the Company Disclosure Letter, neither the
Company nor any of the Company Subsidiaries owns, controls or holds with the
power to vote, directly or indirectly, of record, beneficially or otherwise, any
capital stock or any equity or ownership interest in any Person. The Company has
heretofore delivered to the Parent accurate and complete copies of the
Certificate of Incorporation and By-Laws of the Company and each of the Company
Subsidiaries, as currently in effect.

                  3.2. CAPITALIZATION. (a) The authorized capital stock of the
Company consists of (A) 50,000,000 shares of Common Stock of which, as of the
date hereof, there are 14,405,973 shares issued and outstanding, 2,000,000
shares reserved for issuance under the Company Option Plan, and no shares held
in the Company's treasury, and (B) 10,000,000 shares of Preferred Stock, par
value $0.01 per share ("Company Preferred Stock"), of which as of the date
hereof, none were issued or outstanding. No other capital stock or other
security of the Company is authorized, issued or outstanding. All issued and
outstanding Shares and capital stock of the Company Subsidiaries are duly
authorized, validly issued, fully paid and nonassessable. Except for outstanding
options to acquire not more than 1,234,945 shares issued pursuant to the Company
Option Plan and except as set forth in Section 3.2 of the Company Disclosure
Letter, there are not now, and at the Effec tive Time there will not be, any
securities, options, warrants, calls, subscriptions, pre emptive rights,
earn-outs or other rights or other agreements or commitments whatsoever
obligating the Company or any of the Company Subsidiaries to issue, transfer,
deliver or sell or cause to be issued, transferred, delivered or sold any
additional shares of capital stock or other securities of the Company or any of
the Company Subsidiaries, or obligating the Company or any of the Company
Subsidiaries to grant, extend or enter into any such agreement or commitment.
There are no outstanding contractual obligations of the Company or any of the
Company Subsidiaries to repurchase, redeem or otherwise acquire any shares of
capital stock of the Company or any of the Company Subsidiaries. There are no
outstanding contractual obligations of the Company or any of the Company
Subsidiaries to vote or to dispose of any shares of the capital stock of any of
the Company Subsidiaries.

                  (b) All issuances and grants of all outstanding Options, and
all offerings, sales and issuances by the Company and each of the Company
Subsidiaries of any shares of capital stock, including the Shares, were
conducted in compliance with all applicable 


                                       6
<PAGE>   12

laws and all requirements set forth in all applicable agreements or plans,
except where the failure to comply with such applicable laws, agreements or
plans would not, individually or in the aggregate, have a material adverse
effect on the business or financial condition of the Company and the Company
Subsidiaries taken as a whole.

                  (c) There is no stockholder rights plan (or similar plan
commonly referred to as a "poison pill") or similar existing agreement or plan
under which the Company or any of the Company Subsidiaries is or may become
obligated to sell or otherwise issue any shares of its capital stock or any
other securities.

                  3.3. AUTHORIZATION OF THIS AGREEMENT. The Company has all
requisite corporate power and authority to execute and deliver this Agreement
and the Print and Mail Sale Agreement and, subject to approval by the
stockholders of the Company, to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the Print and Mail
Sale Agreement and the consummation of the transactions contemplated hereby and
thereby have been duly and validly authorized and approved by the Company's
Board of Directors, the Board of Directors has declared the advisability of this
Agreement and the consummation of the transactions contemplated hereby and
thereby, and, except for the adoption of this Agreement by the stockholders of
the Company, no other corporate proceedings on the part of the Company are
necessary to authorize this Agreement or the Print and Mail Sale Agreement or
consummate the transactions contemplated hereby and thereby. Each of this
Agreement and the Print and Mail Sale Agreement has been duly and validly
executed and delivered by the Company, and each of this Agreement and the Print
and Mail Sale Agreement constitutes a valid and binding agreement of the
Company, except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and similar laws of general application
relating to or affecting the rights and remedies of creditors, and the
application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law). Assuming that
none of the Parent, the Purchaser or any affiliate or associate of the Parent or
Purchaser is an Interested Stockholder (as defined by Section 203 of the DGCL)
at the time of execution of this Agreement or the Voting Agreements, this
Agreement, the Merger and the Voting Agreements have been approved by the Board
of Directors of the Company so that Section 203 of the DGCL will not apply to
this Agreement, the Merger, the Voting Agreements or the transactions
contemplated hereby and thereby.

Agree ment, the failure to make or obtain which is reasonably likely to have a
material adverse effect on the ability of the Company to consummate the
transactions contemplated hereby or on the business or financial condition of
the Company and the Company Subsidiaries taken as a whole. Neither the execution
and delivery of this Agreement nor the consum mation of the transactions
contemplated hereby nor compliance by the Company with any of the provisions
hereof will (i) conflict with or result in any violation of any provision of the
Certificate of Incorporation or By-Laws of the Company, (ii) result in a
violation or breach of, or constitute a default or give rise to any right of
termination, cancellation, loss of material benefits or acceleration or give to
any Person any interest in or result in the creation of any Lien upon any of the
properties or assets of the Company or any of the Company Subsidiaries, with or
without notice or lapse of time, or both, under the Certificate of Incorporation
or By-Laws of the Company or any note, bond, mortgage, indenture, license,

(iii) mortgages, leases and other agreements listed on Section 3.4 of the
Company Disclosure Letter, and other conflicts, violations, breaches, defaults
or rights which, either individually or in the aggregate, are not reasonably
likely to have a material adverse effect on the business or financial condition
of the Company and the Company Subsidiaries taken as a whole or to materially
impair the ability of the Company to perform its obligations hereunder or
consummate the transactions contemplated hereby.

agreement or other instrument or obligation to which the Company or any of the
Company Subsidiaries is a party or to which the Company or any of the Company

                                       14

<PAGE>   20



have a material adverse effect on the Company and the Company Subsidiaries taken

Letter, neither the Company nor any of the Company Subsidiaries has given or
received written notice of a material default or notice of termination with

or any contract which is an exhibit to any Company SEC Filing.

                  3.17. EMPLOYEE RELATIONS. Except as set forth in Section 3.17
of the Company Disclosure Letter, neither the Company nor any of the Company
Subsidiaries is a party to or bound by any union or collective bargaining
contract, nor is any such contract currently being negotiated by or on behalf of

1998, no senior operations site manager of the Company or any Company Subsidiary
has, on or prior to the date hereof, indicated to Mahmud U. Haq or Les J.
Kirschbaum an intention to terminate employment with the Company or the Company
Subsidiaries. Since December 31, 1994, Company and the Company Subsidiaries have
not had an "employment loss" within the meaning of the Workers' Adjustment and
Retraining Notification Act ("WARN Act") and the regulations thereunder.

                  3.18. INTELLECTUAL PROPERTY; SOFTWARE. (a) Except as,
individually or in the aggregate, would not reasonably be likely to have a
material adverse effect on the business or financial condition of the Company
and the Company's Subsidiaries taken as a whole, and except as set forth in
Section 3.18 of the Company Disclosure Letter, the conduct of the business of
the Company and the Company Subsidiaries does not, to the knowledge of the
Company, infringe upon any Intellectual Property (as defined below) right of any
Person; and except as set forth in Section 3.18 of the Company Disclosure Letter
and except for such matters as are not reasonably likely to result in liability
to the Company or any of the Company Subsidiaries in excess of $100,000
individually or in the aggregate for all related claims, there are no pending
or, to the knowledge of Company, threatened proceedings or litigation by any
person against the use by the Company or the Company Subsidiaries of any name,
corporate name, fictitious name, software, trademarks, trade names, service
marks, service names, logos, assumed names, copyrights, trade secrets, patents
and all registrations, and applications therefor, and all good will with respect
to the foregoing, which are owned by the Company or any of the Company
Subsidiaries or used in the operation of the Company's or any of the Company
Subsidiaries' business as currently conducted (collectively, the "Intellectual
Property").

<PAGE>   21



                  (b) Except as set forth in Section 3.18 of the Company
Disclosure Letter, the Company owns or has valid licenses or other rights to use
the Intellectual Property which are necessary to permit the Company to conduct
its operations as currently conducted and which are material to its operations.

                  (c) The Company and the Company Subsidiaries have conducted an
analysis of, and developed a compliance program (the "Compliance Program") with
respect to, the effect of Year 2000 (including the correct processing and
calculation of dates prior to, during and after the Year 2000) upon the
software, telecommunications and automated processes of the Company and the
Company Subsidiaries. The Company believes that the costs of implementing the
Compliance Program and completing the modifications necessary to become Year
2000 compliant, if any, will not be material.

                  3.19. ENVIRONMENTAL MATTERS. To the knowledge of the Company,
the Company and the Company Subsidiaries are in compliance with all applicable
health, safety and environmental laws, except to the extent that non-compliance
is not reasonably likely to have a material adverse effect on the business or
financial condition of the Company and the Company Subsidiaries, taken as a
whole. To the knowledge of the Company, except as set forth in Section 3.19 of
the Company Disclosure Letter, there is no matter which is reasonably likely to
expose the Company or any of the Company Subsidiaries to a material liability
pursuant to environmental laws to clean-up or remedy any release of hazardous
substances at any of the real property of the Company and the Company
Subsidiaries.

                  3.20. RELATED PARTY AND AFFILIATE TRANSACTIONS. Except as set
forth in Section 3.20 of the Company Disclosure Letter or in the Company SEC
Filings, no event has occurred that would be required to be reported by Company
pursuant to Item 404 of Regulation S-K promulgated by the SEC. Section 3.20 of
the Company Disclosure Letter identifies each person who is an "affiliate" (as
that term is used in Rule 145 under the Securities Act) of Company as of the
date of this Agreement.

                  3.21. INSURANCE. The Company and the Company Subsidiaries are
covered by valid and currently effective insurance policies issued in favor of
the Company or the Company Subsidiaries that are customary for companies of
similar size and financial condition. All such policies are in full force and
effect, all premiums due thereon have been paid and the Company has complied in
all material respects with the provisions of such policies. The Company has not
been advised in writing within the year prior to the date of this Agreement of
any defense to coverage in connection with any pending claim to coverage
asserted or noticed by the Company under or in connection with any of its
existing insurance policies, other than customary reservations of right. The
Company has not within the twelve months prior to the date of this Agreement
received any written notice from or on behalf of any insurance carrier issuing
policies or binders relating to or covering the Company and the Company
Subsidiaries that there will be a cancellation or non-renewal of existing
policies or binders.

                  3.22. QUESTIONABLE PAYMENTS. To the knowledge of the Company,
within the last year no current or former director, executive, officer,
representative, agent or employee of the Company or any of the Company
Subsidiaries (when acting in such capacity or otherwise on behalf of the Company
or any of the Company Subsidiaries or any of their predecessors) (a) has made
any bribe, rebate, payoff, influence payment, kickback or other unlawful payment
of any nature using corporate funds or otherwise on behalf of the Company or any
of the Company Subsidiaries; or (b) made any material gift that is not
deductible for federal income tax purposes using corporate funds or otherwise on
behalf of the Company or any of the Company Subsidiaries.

                  3.23. PRINT AND MAIL BUSINESS. None of the Print and Mail
Subsidiaries provide accounts receivable management services or teleservices.
None of the assets of any of the Print and Mail Subsidiaries are used in the
operations of the accounts receivable management or teleservices businesses of
the Company and the Company's A/R and Teleservices Subsidiaries. Except as
described in Section 3.23 of the Company Disclosure Letter, there are no (i)
outstanding contracts, liabilities, obligations, loans, advances or guarantees
between or among any of the Print and Mail Subsidiaries, on the one hand, and
the Company or any Company A/R and Teleservices Subsidiary, on the other hand,
or (ii) outstanding guarantees given to any third party by the Company or any
Company A/R and Teleservices Subsidiary with respect to any contracts,
liabilities, obligations, loans, advances of any Print and Mail Subsidiary.

                  3.24. DISCLOSURE. No representation or warranty by the Company
in this Agreement (including the Company Disclosure Letter) contains or will
contain any untrue statement of a material fact or omits or will omit to state
any material fact necessary, in light of the circumstances under which it was
made, to make the statements herein or therein not misleading. There is no fact
known to the Company which would reasonably be expected to have a material
adverse effect on the business or financial condition of the Company and the
Company Subsidiaries taken as a whole which has not been set forth in the
Company SEC Filings or in this Agreement (including the Company Disclosure
Letter).

                         REPRESENTATIONS AND WARRANTIES
                         OF THE PARENT AND THE PURCHASER

                  The Parent and the Purchaser jointly and severally represent
and warrant to the Company as follows:

                  4.1. ORGANIZATION. The Parent is a corporation duly organized,
validly existing and in good standing under the laws of the State of
Pennsylvania. The Purchaser and each of the other Parent Subsidiaries is a
corporation, duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation. Each of the Parent, the
Purchaser and the other Parent Subsidiaries has all requisite power and author
ity to own, lease and operate its properties and to conduct its business as now
being con ducted. Each of the Parent, the Purchaser and the other Parent
Subsidiaries is duly qualified or licensed and in good standing to do business
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 so qualified or licensed and in good standing
would not have a material adverse effect on the business or financial condition
of the Parent, the Purchaser and the other Parent Subsidiaries taken as a
whole. Except as and to the extent set forth in the disclosure letter delivered
by the Parent and the Purchaser to the Company prior to the execution of this
Agreement (the "Parent Disclosure Letter") or in the Parent SEC Filings, the
Parent owns beneficially and of record directly or indirectly all of the issued
and outstanding capital stock of each of the Parent Subsidiaries, free and
clear of any Liens.

                  4.2. CAPITALIZATION. The authorized capital stock of the
Parent consists of (a) 37,500,000 shares of Parent Common Stock of which, as of
the date hereof, there are 21,473,897 shares issued and outstanding, 2,891,235
reserved for issuance under Parent's stock option plans, warrants and
convertible notes, and no shares held in the Parent's treasury, and (b)
5,000,000 shares of preferred stock, of which as of the date hereof, no shares
were issued or outstanding. No other capital stock of the Parent is authorized,
issued or outstanding. All issued and outstanding Shares and capital stock of
the Company Subsidiaries are duly authorized, validly issued, fully paid and
nonas sessable.

                  4.3. AUTHORIZATION OF THIS AGREEMENT. Each of the Parent and
the Purchaser 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 and the consummation of the
transactions contemplated hereby have been duly and validly authorized and
approved by the Parent's and the Purchaser's respective Board of Directors, each
of the Board of Directors of the Parent and the Purchaser has declared the
advisability of this Agreement and the consummation of the transactions
contemplated hereby, and, no other corporate proceedings on the part of the
Parent and the Purchaser are necessary to authorize this Agreement or consummate
the transactions contemplated hereby. This Agreement has been duly and validly
executed and 





                                      18

<PAGE>   25

delivered by the Parent and the Purchaser, and this Agreement constitutes a
valid and binding agreement of the Parent and the Purchaser, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium and similar laws of general application relating to
or affecting the rights and remedies of creditors, and the application of
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

                  4.4. CONSENTS AND APPROVALS; NO VIOLATION. Except for (i)
filings required under the Securities Act and the Exchange Act, (ii) the filing
of a Pre-Merger Notification and Report Form by the Company under the HSR Act,
(iii) the filing and recordation of appropriate merger documents as required by
the DGCL and, if applicable, the laws of other states in which the Parent or the
Purchaser is qualified to do business, and (iv) filings under securities or blue
sky laws or takeover statutes of the various states, no filing with, and no
permit, authorization, consent or approval of, any public body or authority is
necessary for the consummation by the Parent and the Purchaser of the trans
actions contemplated by this Agreement, the failure to make or obtain which is
reasonably likely to have a material adverse effect on the ability of the Parent
or the Purchaser to consummate the transactions contemplated hereby or on the
business or financial condition of the Parent, the Purchaser and the other
Parent Subsidiaries taken as a whole. Neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby nor
compliance by either the Parent or the Purchaser with any of the provisions
hereof will (i) conflict with or result in any violation of any provision of the
Certificate of Incorporation or By-Laws of the Parent or the Purchaser, (ii)
result in a violation or breach of, or constitute a default or give rise to any
right of termination, cancellation, loss of material benefits or acceleration or
give to any Person any interest in or result in the creation of any Lien upon
any of the properties or assets of the Parent, the Purchaser or any of the other
Parent Subsidiaries, with or without notice or lapse of time, or both, under the
Certificate of Incorporation or the By-Laws of the Parent or the Purchaser or
any note, bond, mortgage, indenture, license, benefit plan, agreement or other
instrument or obligation to which the Parent, the Purchaser or any of the other
Parent Subsidiaries is a party or by which any of them or any of their
properties or assets is bound or (iii) assuming the truth of the representations
and warranties of the Company contained herein and their compliance with all
agreements contained herein and assuming the due making or obtaining of all
filings, permits, authorizations, consents and approvals referred to in the
preceding sentence, violate any statute, rule, regulation, order, injunction,
writ or decree of any public body or authority by which the Parent, the
Purchaser or any of the other Parent Subsidiaries or any of their respective
assets or properties is bound, excluding from the foregoing clauses (ii) and
(iii) mortgages, leases and other agreements listed on Section 4.4 of the Parent
Disclosure Letter, and other conflicts, violations, breaches or defaults which,
either individually or in the aggregate, are not reasonably likely to have a
material adverse effect on the business or financial condition of the Parent,
the Purchaser and the other Parent Subsidiaries taken as a whole or to
materially impair the ability of the Parent or the Purchaser to perform their
respective obligations hereunder or consummate the transactions contemplated
hereby.

this Agreement, or changes generally affecting companies operating in the
industries in which the Parent and the Parent Subsidiaries operate.

                  4.7. INFORMATION IN PROXY STATEMENT/PROSPECTUS, REGISTRATION
STATEMENT AND HSR FILINGS. The S-4 Registration Statement (or any amendment

<PAGE>   27

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 are
made, not misleading, except that no representation is made by Parent or
Purchaser with respect to statements made therein based on information supplied
by the Company for inclusion in the S-4 Registration Statement. None of the
information supplied by Parent or Purchaser for inclusion or incorporation by
reference in the Proxy Statement/Prospectus will, at the date mailed to
shareholders and at the time of the Company Stockholders Meeting, contain any

financial condition of the Parent and the Parent Subsidiaries taken as a whole
which has not been set forth in the Parent SEC Filings or in this Agreement
(including the Parent Disclosure Letter).

                  (a) amend the Certificate of Incorporation or By-Laws of
         Parent in a manner which would materially adversely change the rights
         of holders of Parent Common Stock;

                  (b) during the Averaging Period (as hereinafter defined), pay
         any dividend or other distribution (whether in cash, stock or property

                              ADDITIONAL AGREEMENTS

                  6.1. PROXY STATEMENT/PROSPECTUS; S-4 REGISTRATION STATEMENT.
In connec tion with the solicitation of approval of the principal terms of this
Agreement and the Merger by the Company's stockholders, the Company, the Parent
and the Purchaser shall as promptly as practicable prepare and file with the
SEC, on a confidential basis (if practicable), a preliminary proxy statement
relating to the Merger and this Agreement and use commercially reasonable
efforts to obtain and furnish the information required to be 


                                       24
<PAGE>   31

included by the SEC in the Proxy Statement/Prospectus (as hereinafter defined).
The Company, after consultation with the Parent, shall respond as promptly as
practicable to any comments made by the SEC with respect to the preliminary
proxy statement and shall cause a definitive proxy statement to be mailed to its
shareholders at the earliest practicable date after the S-4 Registration
Statement (as hereinafter defined) has been declared effective. Such definitive
proxy statement shall also constitute a prospectus of Parent with respect to the
Parent Common Stock to be issued in the Merger (such proxy statement and
prospectus are referred to herein as the "Proxy Statement/Prospectus"), which
prospectus is to be filed with the SEC as part of a registration statement on
Form S-4 (the "S-4 Registration Statement") for the purpose of registering under
the Securities Act the Purchaser Common Stock to be issued pursuant to Section
2.1(a). The Parent shall as promptly as practicable prepare and file with the
SEC the S-4 Registration Statement after the SEC has advised that it will not
review, or has no further comments on, the Proxy Statement/Prospectus. The
Parent, after consultation with the Company, shall respond as promptly as
practicable to any comments made by the SEC with respect to the S-4 Registration
Statement, and shall use all commercially reasonable efforts to have the S-4
Registration Statement declared effective by the SEC. The Parent shall also take
any action required to be taken under applicable state securities laws in
connection with the issuance of Parent Common Stock in the Merger to
stockholders of the Company; PROVIDED, HOWEVER, that Parent shall not be
required (i) to qualify to do business as a foreign corporation in any
jurisdiction in which it is now qualified or (ii) to file a general consent to
service of process in any jurisdiction. The Company shall furnish all
information concerning the Company and the holders of the Shares as may be
reasonably requested by Parent in connection with such action. If at any time
prior to the Effective Time any information relating to the Company or Parent,
or any of their respective affiliates, officer or directors, should be
discovered by the Company or Parent which should be set forth in an amendment or
supplement either the S-4 Registration Statement or the Proxy
Statement/Prospectus, so that any of such documents would not include any
misstatement of a material fact or omit to state any material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, the party which discovers such information shall promptly
notify the other parties hereto and an appropriate amendment or supplement
describing such information shall be promptly filed with the SEC and, to the
extent required by law, disseminated to the stockholders of the Company.

                  6.2. ACCESS TO INFORMATION. (a) The Company will (i) give
Parent and its authorized representatives reasonable access during normal
business hours to all offices and other facilities and to all books and records
of the Company and the Company Subsidiaries, in order to permit Parent to make
such inspections as it may reasonably require and (ii) will furnish Parent with
a copy of each report, schedule and other document filed or received by it,
during the period between the date hereof and the Effective Date, pursuant to
the requirements of federal and state securities laws and such financial and
operating data and other information with respect to the business and properties
of the Company and the Company Subsidiaries as Parent may from time to time
reasonably request.

                  (b) Parent will furnish the Company with a copy of each

representatives shall continue to abide by the provisions of the Confidentiality
Agreement, dated January 25, 1999 (the "Confidentiality Agreement"), by and
between the Parent and the Company.

                  6.3. CONSENTS. (a) The Parent and the Company each shall use
their commercially reasonable efforts to obtain all consents of third parties
under the agreements set forth in Section 6.3 of the Company Disclosure Letter
or the Parent Disclosure Letter, as the case may be, obtain all material
consents of governmental authorities, and to make all governmental filings,
necessary to the consummation of the transactions contemplated by this
Agreement. The Company, the Parent and the Purchaser shall as soon as
practicable file Pre-Merger Notification and Report Forms under the HSR Act with
the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and shall use their
commercially reasonable efforts to respond as promptly as practicable to all
inquiries received from the FTC or the Antitrust Division for additional
information or documentation.

                  (b) Each of the parties hereto agrees to furnish to each other
party hereto such necessary information and commercially reasonable assistance
as such other party may request in connection with its preparation of necessary
filings or submissions to any regulatory or governmental agency or authority,
including, without limitation, any filing necessary under the provisions of the
HSR Act, or any other federal, state, local or foreign statute or regulations.
Each of the parties shall respond as promptly as practicable to (i) any
inquiries or requests from the FTC or the Antitrust Division for additional
information or documentation and (ii) any inquiries or requests received from
any state attorney general or other governmental entity in connection with
antitrust or related matters. Each of the parties shall (1) give the other party
prompt notice of the commence ment of any claim, action, suit or proceeding by
or before any governmental entity with respect to the Merger or any of the
transactions contemplated by this Agreement, (2) keep the other party informed
as to the status of any such claim, action, suit or pending or proceeding, and
(3) promptly inform the other party of any communication to or from the FTC or
the Antitrust Division or any other governmental entity regarding the Merger or
the transactions contemplated by this Agreement. Each of the parties will
consult and cooperate with one another, and will consider in good faith the
views of one another, in connection with any analysis, appearance, presentation,
memorandum, brief, argument, opinion or proposal made or submitted in connection
with any claim, action, suit or proceeding under or relating to the HSR or any
other federal or state antitrust or fair trade law. In addition, except as may
be prohibited by any governmental entity or by any applicable federal, state,
local or foreign laws, ordinances or regulations, in connection with any claim,
action, suit or proceeding under or relating to the HSR Act or any other 


                                       26
<PAGE>   33

federal or state antitrust or fair trade law or any other similar claim, action,
suit or proceeding, each of the parties will permit authorized representatives
of the other party to be present, to the extent reasonably practicable, at each
meeting or conference relating to any such claim, action, suit or proceeding and
to have access to and be consulted in connection with any document, opinion or
proposal made or submitted to any governmental entity in connection with any
such claim, action, suit or proceeding

                  (c) Notwithstanding anything to the contrary contained in this

dispose or cause any of the Parent Subsidiaries to dispose of any assets, or to
commit to cause the Company or any of the Company Subsidiaries to dispose of any
assets; (ii) to discontinue or cause any of the Parent Subsidiaries to
discontinue offering any product, or to commit to cause the Company or any of

of the Parent Subsidiaries to hold separate any assets or operations, or to
commit to cause the Company or any of the Company Subsidiaries to hold separate
any assets or operations; or (v) to make or cause any of the Parent Subsidiaries
to make any commitment (to any governmental entity or otherwise) regarding its
future operations or the future operations of the Company or any of the Parent
Subsidiaries or Company Subsidiaries, if any of the actions described in (i)-(v)
above would materially interfere with Parent's anticipated benefits from the
trans actions contemplated hereby or have a material adverse effect on Parent.

                  6.4. BOARD ACTIONS; COMPANY STOCKHOLDER MEETING. (a) The Board
of Directors of the Company has determined that the Merger is advisable and in
the best interests of its stockholders and, subject to Section 6.8 hereof, (i)
the Board of Directors of the Company will recommend to the Company's

Directors of the Company has recommended that the Company's stockholders vote in
favor of adopt and approve the Merger at the Company's Stockholders Meeting; and
(iii) neither the Board of Directors of the Company nor any committee thereof

                                       27
<PAGE>   34

the purpose of approving this Agreement and the transactions contemplated by
this Agreement. The Company will convene the Company Stockholder Meeting, as
promptly as practicable and in any event use its reasonable best efforts to
convene such meetings within 45 days after the Form S-4 is declared effective by
the SEC.

                  6.5. COMMERCIALLY REASONABLE EFFORTS. Subject to the terms and
conditions hereof, each of the parties hereto agrees to use its commercially
reasonable efforts consistent with applicable legal requirements to take, or
cause to be taken, all action, and to do, or cause to be done, all things
necessary or proper and advisable under applicable laws and regulations to
ensure that the conditions set forth in Article VII hereof are satisfied and to

transactions contemplated by this Agreement.

                  6.6. PUBLIC ANNOUNCEMENTS. The Parent and the Company will
obtain the prior written consent of the other before issuing any press release

                  6.7. CONSENT OF THE PARENT. The Parent, as the sole
stockholder of the Purchaser, by executing this Agreement consents to the
execution and delivery of this Agreement by the Purchaser and the consummation
of the Merger and the other transactions contemplated hereby, and such consent
shall be treated for all purposes as a vote duly cast at a meeting of the
stockholders of the Purchaser held for such purpose.

                  6.8. NO SOLICITATION. (a) The Company shall not, nor shall it
authorize or permit any of the Company Subsidiaries to, nor shall it authorize
or permit any of its, or the Company Subsidiaries', directors, officers or
employees or any investment banker, financial advisor, attorney, accountant or
other representative retained by or acting on behalf of it or any of the Company
Subsidiaries to, directly or indirectly through another Person, (i) solicit,
initiate or knowingly encourage (including by way of furnishing non-public
information), or take any other action designed to facilitate, any inquiries or
the making of any proposal which constitutes a Company Takeover Proposal (as
hereinafter defined), (ii) participate in any discussions or negotiations

intent, agreement in principle, acquisi tion agreement or similar agreement
(each a "Company Acquisition Agreement") with respect to a Company Takeover
Proposal, or (iv) approve, endorse or recommend a Company Takeover Proposal;
PROVIDED, HOWEVER, that if and to the extent that, at any time prior to the time
of the adoption of this Agreement by the Company's stockholders, the Board of
Directors of the Company determines in good faith, after consultation with
outside counsel, that failing to do so would violate its fiduciary duties to the
Company's stockholders under applicable law, the Company may, in response to any
Company Takeover Proposal which is a Company Superior Proposal (as hereinafter
defined) and which was not solicited by it and which did not otherwise result
from a breach of this Section 6.8(a); (x) furnish information with respect to
the Company and the Company Subsidiaries to any Person inquiring about or making
a Company Takeover Proposal 


                                       28
<PAGE>   35

pursuant to a customary confidentiality agreement (as determined by the Company
based on the advice of its outside counsel containing limitations no less
restrictive than the limitations imposed on Parent pursuant to the
Confidentiality Agreement); and (y) participate in discussions or negotiations
regarding such Company Takeover Proposal; PROVIDED that prior to or at the time
of furnishing any such information or entering into such discussions or
negotiations, the Company shall: (1) inform Parent in writing as to the fact
such information is to be provided, (2) furnish to Parent the identity of the
recipient of such information and/or the potential acquirer and the terms of
such Company Takeover Proposal and (3) furnish to or notify Parent of the
availability of such written information to Parent (to the extent such
information has not been previously furnished by the Company to Parent). Without
limiting the generality of the foregoing, the Company acknowledges and agrees
that any violation of the restrictions set forth in the preceding sentence by
any director, officer, employee, investment banker, financial advisor, attorney,
accountant or other representative of the Company or any of the Company
Subsidiaries shall be deemed to constitute a breach of this Section 6.8(a) by
the Company. The Company agrees that it will immediately cease and cause to be
terminated any existing discussions with any person that relate to any Company
Takeover Proposal. For purposes of this Agreement, "Company Takeover Proposal"
means any inquiry, proposal or offer from any Person relating to any Company
Takeover Event. For purposes of this Agreement, "Company Takeover Event" means
any direct or indirect acquisition or purchase of a business that constitutes
10% or more of the net revenues, net income or assets of the Company and the
Company Subsidiaries (other than the Print and Mail Subsidiaries (as hereinafter
defined)), taken as a whole, or 10% or more of any class of equity securities of
the Company, any tender offer or exchange offer that if consummated would result
in any Person beneficially owning 10% or more of any class of any equity
securities of the Company, or any sale, lease, exchange, transfer or license of
assets, or any merger, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving the Company (or any
Company Subsidiary (other than the Print and Mail Subsidiaries)) whose business
constitutes 10% or more of the net revenues, net income or assets of the Company
and the Company Subsidiaries taken as a whole, other than the transactions
contemplated by the Print and Mail Sale Agreement.

                  (b) Except as expressly permitted by this Section 6.8(b), the
Board of Directors of the Company shall not (i) withdraw or modify or propose
publicly to withdraw or modify, in a manner adverse to the Parent and the
Purchaser, its approval or recommendation of this Agreement, or (ii) approve or
recommend, or propose publicly to approve or recommend any Company Takeover
Proposal, unless (x) such Company Takeover Proposal is a Company Superior
Proposal, (y) the Board of Directors of the Company determines in good faith,
after consultation with outside counsel, that in light of a Company Superior
Proposal it is necessary to do so in order to comply with its fiduciary duties
under applicable law, and (z) neither the Company nor any Company Subsidiary nor
any representative of the Company or a Company Subsidiary shall have caused the
Company Superior Proposal to be made in violation of Section 6.8(a). For
purposes of this Agreement, the term "Company Superior Proposal" means any bona
fide written proposal to acquire, directly or indirectly, for consideration
consisting of cash 


                                       29
<PAGE>   36

and/or securities, more than a majority of the Shares then outstanding or all or
substantially all the assets of the Company, that the Board of Directors of the
Company determines in good faith, after taking into account advice from its
financial advisor, to be more favorable from a financial point of view to the
Company and its stockholders than the Merger.

                  (c) Nothing contained in this Section 6.8(c) shall prohibit
the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making
any disclosure to the Company's stockholders if, in the good faith judgment of
the Board of Directors of the Company, after consultation with outside counsel,
such disclosure is required under applicable law; PROVIDED that the Company does
not amend, withdraw or modify, or propose to amend, withdraw or modify, its
position with respect to the Merger, or approve, recommend or propose publicly
to approve or recommend a Company Takeover Proposal, unless the Company and the
Board of Directors has complied with the provisions of Section 6.8(b).

                  (d) Anything in this Agreement to the contrary
notwithstanding, the Company shall submit this Agreement for approval to the
stockholders of the Company at the Company Stockholder Meeting whether or not
the Board of Directors determines at any time subsequent to the date hereof that
the Agreement is no longer advisable and recommends that the stockholders reject
it.

                  6.9. INDEMNIFICATION. (a) For a period of six years after the
Effective Time, the Parent shall, and shall cause the Surviving Corporation to,
indemnify, defend and hold harmless the present and former officers, directors,
employees and agents of the Company and the Company Subsidiaries (other then the
Print and Mail Subsidiaries) (collectively, the "Indemnified Parties") from and
against, and pay or reimburse the Indemnified Parties for, all losses,
obligations, expenses, claims, damages or liabilities (whether or not resulting
from third-party claims and including interest, penalties, out-of-pocket
expenses and attorneys' fees incurred in the investigation or defense of any of
the same or in asserting any of their rights hereunder) resulting from or
arising out of actions or omissions occurring on or prior to the Effective Time
(including, without limitation, the transactions contemplated by this Agreement)
to the full extent permitted or required under applicable law as of the
Effective Time and, in the case of indemnification by the Surviving Corporation,
to the extent permitted under the provisions of the Certificate of Incorporation
and the By-Laws of the Company in effect at the date hereof (which provisions
shall not be amended in any manner which adversely affects any Indemnified
Party, for a period of six years), including provisions relating to payment and
advances of expenses incurred in the defense of any action or suit; PROVIDED
that in the event any claim or claims are asserted or made within such six-year
period, all rights to indemnification in respect of each such claim shall
continue until final disposition of such claim. Without limiting the foregoing,
in any case in which approval by the Surviving Corporation is required to
effectuate any indemnification, the Parent shall cause the Surviving Corporation
to direct, at the election of the Indemnified Party, that the determination of
any such approval shall be made by independent counsel jointly selected by the
Indemnified Party and the Parent.



                                       30
<PAGE>   37

                  (b) For not less than six years after the Effective Time, the
Parent and the Purchaser shall maintain in effect directors' and officers'
liability insurance covering the Indemnified Parties who are currently covered
by the Company's existing directors' and officers' liability insurance, on terms
and conditions no less favorable to such directors and officers than those in
effect on the date hereof; PROVIDED that the deductible thereunder (which shall
be paid by the Parent) may be increased to no more than $25,000; and, PROVIDED,
FURTHER, that in no event shall the Parent be required to expend in any one year
an amount in excess of $250,000; and, PROVIDED, FURTHER, that if the annual
premiums of such insurance coverage exceed such amount, the Parent shall be
obligated to obtain a policy with the greatest coverage available for a cost not
exceeding such amount.

                  (c) Any Indemnified Party wishing to claim indemnification
under Section 6.9(a) shall provide notice to the Parent promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and (i) the Parent shall retain counsel satisfactory to the Parent, the
Indemnified Party and the insurer under any applicable directors' and officers'
liability insurance, (ii) the Parent shall pay all reasonable fees and expenses
of such counsel for the Indemnified Party promptly as statements therefor are
received, and (iii) the Parent will use all reasonable efforts to assist in the
vigorous defense of any such matter, PROVIDED that neither Parent nor the
Company shall be liable for any settlement of any claims effected without its
written consent, which consent, however, shall not be unreasonably withheld; and
PROVIDED, FURTHER, that neither Parent nor Company shall be obligated to pay the
fees and expenses of more than one counsel for all Indemnified Parties in any
single action unless in the reasonable judgment of any such Indemnified Party a
conflict of interest may exist between such Indemnified Party and any other
Indemnified Parties with respect to any claims. The omission by any Indemnified
Party to give notice as provided herein shall not relieve the Parent of its
indemnification obligation under this Agreement except to the extent that such
omission results in a failure of actual notice to the Parent and the Parent is
damaged as a result of such failure to give notice. The Parent and the
Indemnified Party shall cooperate in the defense of any action or claim subject
to this Section 6.9, including but not limited to furnishing all available
documentary or other evidence as is reasonably requested by the other.

                  (d) This Section 6.9 is intended for the benefit of the
Indemnified Parties whether or not parties to this Agreement and each of the
Indemnified Parties shall be entitled to enforce the covenants contained herein.

                  (e) If the Parent or the Surviving Corporation or any of their
respective successors or assigns (i) reorganizes or consolidates with or merges
into any other Person and is not the resulting, continuing or surviving
corporation or entity of such reorganiza tion, consolidation or merger, or (ii)
liquidates, dissolves or transfers all or substantially all of its properties
and assets to any Person or Persons, then, and in such case, proper provision
will be made so that the successors and assigns of the Surviving Corporation



                                       31
<PAGE>   38

assumes all of the obligations of the Parent or the Surviving Corporation, as
the case may be, set forth in this Section 6.9.

                  6.10. EMPLOYEE BENEFITS. Until the first anniversary of the
Closing, Parent shall maintain or caused to be maintained for the benefit of
each employee of the Parent or any of its Subsidiaries who was an employee of
the Company or any of its Subsidiaries immediately prior to the Closing employee
benefit plans and programs that provide such employee with benefits, rights and
entitlements which are comparable to similarly situated employees of the Parent.
Following the Effective Time, Parent shall cause the Surviving Company to honor
in accordance with their terms all employment, severance and other compensation
agreements and arrangements existing on or prior to the execution of this
Agreement which are between the Company and any of the Company Subsidiaries and
any officer, director or employee thereof.

                  6.11. TAX COVENANTS. Whether before or after the Effective
Time, neither the Parent nor the Company shall take (or permit any of their
Affiliates to) take any action that could reasonably be expected to jeopardize
qualification of the Merger as a reorganization within the meaning of Section
368(a) of the Code. Each of the Parent and the Company shall use its respective
commercially reasonable efforts (I) to cause the Merger to qualify as a
reorganization under the provisions of Section 368(a) of the Code and (II) to
cause its respective officers to furnish such representations to Blank Rome
Comisky & McCauley LLP ("Parent's Counsel") and Katten Muchin & Zavis
("Company's Counsel") as may be reasonably requested to enable such counsel to
deliver the opinions described in Sections 7.2(d) and 7.3(c).

                  6.12. PRINT AND MAIL SALE AGREEMENT. The Company shall use its
commercially reasonable efforts to consummate the transactions contemplated by
the Print and Mail Sale Agreement in accordance with its terms. The Company
shall advise Parent of, and consult with Parent with respect to, material
developments in connection with such sale. Neither the Company nor any Company
Subsidiary shall agree or consent to any amendment, waiver, consent,
modification or other change to, or the termination of, the Print and Mail Sale
Agreement unless it shall have first received the approval of Parent (which
shall not unreasonably be withheld).

<PAGE>   39

         restraining order, preliminary or permanent injunction or other order
         issued by any court of competent jurisdiction or other legal restraint

         commercially reasonable efforts to prevent the entry of any such
         injunction or other order and to appeal as promptly as possible any
         injunction or other order that may be entered.

                  (b) This Agreement shall have been approved and adopted by the
         affirmative vote of the holders of the requisite number of shares of

         required in connection with the Merger to file a Pre-Merger
         Notification and Report Form under the HSR Act with the FTC and the
         Antitrust Division shall have made such filing and the applicable
         waiting period with respect to each such filing (including any
         extension thereof by reason of a request for additional information)
         shall have expired or been terminated.

                  (d) The S-4 Registration Statement shall have become effective
         under the Securities Act and shall not be the subject of any stop order
         or proceedings seeking a stop order and no stop order or similar

         contained in Section 3.2 shall be true and correct as of the date of
         this Agreement and as of the Closing Date as though made on and as of
         the Closing Date and the representations and warranties of the Company
         contained in this Agreement that are not so qualified shall be true and
         correct in all material respects as of the date of this Agreement and
         as of the Closing Date as though made on and as of the Closing Date
         (except in each case to the extent any such representation or warranty
         expressly speaks as of an earlier specified date, in which case, as of
         such date), except (i) in each case where the failure of the
         representations and warranties (other than the representations and
         warranties set forth in Section 3.2) to be so true and correct (without
         giving effect to any qualification as to "material,"
         "materiality,""material adverse effect" or similar qualifications) are
         not, individually or in the aggregate, reasonably likely to have a
         material adverse effect on the Parent and the Parent Subsidiaries taken
         as a whole or on the Company and the Company Subsidiaries (excluding
         the Print 


                                       33
<PAGE>   40

         and Mail Subsidiaries) taken as a whole, or (ii) in each case where the
         failure of such representations and warranties to be so true and
         correct (x) is with respect to representations and warranties relating
         to the Print and Mail Business and (y) the sale of the Print and Mail
         Business is consummated in accordance with the terms of the Print and
         Mail Sale Agreement and (iii) in the case of Section 3.2, so long as
         the number of shares of Company Common Stock outstanding or subject to
         options on the Effective Date does not exceed that amount set forth in
         Section 3.2 by more than 10,000 shares or by more than 10,000 option
         shares in the aggregate, provided that the exercise prices of such
         additional options equal or exceed $10.50 per share.

                  (b) The Company shall have, in all material respects,
         performed all covenants and agreements and complied with all conditions
         required by this Agreement to be performed or complied with by the
         Company prior to or on the Closing Date. The Company shall deliver to
         Parent a certificate of its Chief Executive Officer, solely in his
         capacity as such, as to the satisfaction of the conditions in
         paragraphs (a) and (b) of this Section 7.2.

                  (c) There shall not be pending any action, suit or proceeding
         by a governmental entity (a) challenging or seeking to restrain or
         prohibit the consum mation of the Merger; (b) relating to the Merger
         and seeking material monetary damages from the Parent, the Company or
         any of the Parent or Company Subsidiary; (c) seeking to prohibit or
         limit in any material respect Parent's ability to vote, receive
         dividends with respect to or otherwise exercise ownership rights with
         respect to the capital stock of the Company; or (d) which would
         materially and adversely affect the right of Parent, the Company or any
         Parent or Company Subsidiary to own the assets or operate the business
         of the Company after the Effective Time; PROVIDED that Parent shall use
         reasonable efforts to resolve such matters.

                  (d) There shall not be pending any actions, suits or
         proceeding: (i) which individually or in the aggregate, taking into
         account the totality of the facts and circumstance and the probability
         of an adverse judgement, are reasonably likely to have material adverse
         effect on the Company and the Company A/R and Teleservices Subsidiaries
         taken as a whole or on the Parent and the Parent Subsidiaries taken as
         a whole and (ii) which (A) challenges or seeks to restrain or prohibit
         the consummation of the Merger; (B) relates to the Merger and seeks to
         obtain from Parent or any of its subsidiaries damages; (C) seeks to
         prohibit or limit in any material respect Parent's ability to vote,

         any such claim, action, suit or proceeding will be fully reimbursed by
         insurance coverage pursuant to insurance policies held by Company or
         Parent, such damages shall be disregarded in determining the material
         adverse effect of such claim, action, suit or proceeding on the policy
         holder.

<PAGE>   41

                  (e) Parent shall have received from Parent's Counsel an
         opinion in substantially the form attached hereto as Annex V, dated on
         or about the date of mailing of the Proxy Statement/Prospectus, which
         opinion shall be reconfirmed at the Effective Time, substantially to
         the effect that the Merger will be treated for U.S. federal income tax
         purposes as a reorganization within the meaning of Section 368(a) of
         the Code. In rendering such opinion, Parent's Counsel shall be entitled
         to request and rely upon representations contained in certificates of
         officers of Parent and Company, which certificates are in substantially
         the form attached hereto as Annex III and Annex IV, as the case may be.

                  (f) Since the date hereof, there shall not have been any
         material adverse change in the business or financial condition of the
         Company and the Company Subsidiaries taken as a whole, other than
         changes in general economic or business conditions, changes that may
         result from the public announcement of this Agreement, changes
         generally affecting companies operating in the industries in which the
         Company and the Company Subsidiaries operate or changes solely
         affecting the Print and Mail Subsidiaries.

                  (g) The sale of the Print and Mail Subsidiaries shall have
         been consummated in accordance with the terms of the Print and Mail
         Sale Agreement.

                  (h) Neither the Parent nor the Purchaser may rely on the
         failure of any condition set forth in this Article VII to be satisfied
         if such failure was caused by the Parent's or the Purchaser's failure
         to use commercially reasonable efforts to consummate the transactions
         contemplated by this Agreement.

                  7.3. CONDITIONS TO THE OBLIGATIONS OF THE COMPANY. The
obligations of the Company to effect the Merger shall be subject to the
fulfillment, at or prior to the Effective Time, of the following conditions:

                  (a) The representations and warranties of the Parent and the
         Purchaser contained in this Agreement that are qualified by materiality
         shall be true and correct in all respects as of the date of this
         Agreement and as of the Closing Date and the representations and
         warranties of the Parent contained in this Agreement that are not so
         qualified shall be true and correct in all material respects as of the
         date of this Agreement and as of the Closing Date as though made on and
         as of the Closing Date (except in each case to the extent any such
         representation or warranty expressly speaks as of an earlier specified
         date, in which case, as of such date), except in each case where the
         failure of the representations and warranties to be so true and correct
         (without giving effect to any qualification as to "material,"
         "materiality,""material adverse effect" or similar qualifications) are
         not, individually or in the aggregate, reasonably likely to have a
         material adverse effect on the Parent and the Parent Subsidiaries taken
         as a whole.



                                       35
<PAGE>   42

                  (b) The Parent and the Purchaser shall have, in all material
         respects, performed all covenants and agreements and complied with all
         conditions required by this Agreement to be performed or complied with
         by the Parent and the Purchaser prior to or on the Closing Date. The
         Parent shall deliver to Company a certificate of its Chief Executive
         Officer, solely in his capacity as such, as to the satisfaction of the
         conditions in paragraphs (a) and (b) of this Section 7.3.

                  (c) Company shall have received from Company's Counsel an
         opinion in substantially the form attached hereto as Annex VI, dated on
         or about the date of mailing of the Proxy Statement/Prospectus, which
         opinion shall be reconfirmed at the Effective Time, substantially to
         the effect that the Merger will be treated for U.S. federal income tax
         purposes as a reorganization within the meaning of Section 368(a) of
         the Code. In rendering such opinion, Company's Counsel shall be
         entitled to request and rely upon representations contained in
         certificates of officers of Parent and Company, which certificates are
         in substantially the form attached hereto as Annex III and Annex IV, as
         the case may be.

                  (d) The Company may not rely on the failure of any condition
         set forth in this Article VII to be satisfied if such failure was
         caused by the Company's failure to use commercially reasonable efforts
         to consummate the transactions contemplated by this Agreement.

the provisions of Sections 103 and 251 or 253 of the DGCL and shall take any and
all other lawful actions and do any and all other lawful things necessary to
cause the Merger to become effective.

         HOWEVER, that the right to terminate this Agreement shall not be
         available to any party whose failure to fulfill any obligation under or
         breach of this Agreement has been the cause of, or resulted in, the
         failure of the Merger to have occurred on or before the aforesaid date;

                  (c) by either the Parent or the Company, if any court of
         competent jurisdiction in the United States or other governmental

         otherwise prohibiting the Merger, and such order, decree, ruling or
         other action shall have become final and non-appealable;

                  (d) by either the Parent or the Company, if the approval of
         the Merger by the stockholders of the Company shall not have been

         vote held at a duly held meeting of such stockholders or at any
         adjournment or postponement thereof;

                  (e) by the Company:

         breach within fifteen (15) business days after receiving notice of such
         breach (but only if such breach is capable of being cured) and such
         breach would cause any of the conditions set forth in Section 7.3(a) or
         (b) not to be satisfied at the time of such breach or at the time such
         representation or warranty was or shall have become inaccurate or, if
         capable of being cured, at the end of such cure period;

                           (ii) if the arithmetic per share average of the last

         greater number or combined, whether by reverse stock split or
         otherwise, into a lesser number).

         become inaccurate, in either case such that the Company fails to cure
         such breach within fifteen (15) business days after receiving notice of
         such breach (but only if such breach is capable of being cured) and
         such breach would cause any of the conditions set forth in Section
         7.2(a) or (b) not to be satisfied at the time of such breach or at the
         time such representation or warranty was or shall have become
         inaccurate, or, if capable of being cured, at the end of such cure
         period;

                           (ii) if (a) the Board of Directors of the Company
         shall have failed to recommend, or shall for any reason have withdrawn

         recommendation in favor of, the adoption and approval of the Merger;
         (b) the Company shall have failed to include in the Proxy
         Statement/Prospectus the recommendation of the Board of Directors of

agrees that any termination by the Parent shall be conclusively binding upon it,
whether given expressly on its behalf or not, and the Company shall have no
further obligation with respect to it. If this Agreement is terminated as
provided herein, no party hereto shall have any liability or further obligation
to any other party to this Agreement; PROVIDED that any termination shall be
without pre judice to the rights of any party hereto arising out of any
intentional breach by any other party of any covenant or agreement contained in

                  10.1. AMENDMENT AND MODIFICATION. Subject to applicable law,
this Agreement may be amended, modified or supplemented only by written
agreement of the Parent, the Purchaser and the Company at any time prior to the

after this Agreement is adopted by the Company's stockholders, no such amendment
or modification shall be made that reduces the amount or changes the form of the

of the Company's stockholders hereunder, without the further approval of such
stockholders.

waived by the Company or the Parent, respectively, only by a written instrument
signed by the party granting such waiver, but such waiver or failure to insist
upon strict compliance with such obligation, covenant, agreement or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure. Whenever this Agreement requires or permits consent by or on
behalf of any party hereto, such consent shall be given in writing in a manner
consistent with the requirements for a waiver of compliance as set forth in this
Sec tion 10.2. The Purchaser hereby agrees that any consent or waiver of

Section 7(a), or (ii) such time as that Stockholder shall have satisfied the
requirements of Rule 145(d)(2) or (d)(3); provided, however, nothing in this

signed by the party against whom enforcement is sought. Except as otherwise
expressly provided herein, no failure to exercise, delay in exercising, or

of or shall preclude any other for further exercise of, any right, power or
remedy.

                  (e) SEVERABILITY. If any provision of this Agreement or any
part of any such provision is held under any circumstances to be invalid or

amended to conform to applicable laws so as to be valid and enforceable to the
fullest possible extent, (ii) the invalidity or unenforceability of such

affect the validity or enforceability of the remainder of such provision or the
validity or enforceability of any other provision of this Agreement. Each

Agreement, and each part of each provision of this Agreement is separable from
every other part of such provision.

of counterparts, each of which when so executed and delivered shall be an
original hereof, and it shall not be necessary in making proof of this Agreement
to produce or account for more than one counterpart hereof.

                  (g) SECTION HEADINGS. Section and subsection headings in this
Agreement are for convenience of reference only, do not constitute a part of
this Agreement, and shall not affect its interpretation.

                  (h) REFERENCES. All words used in this Agreement shall be
construed to be of such number and gender as the context requires or permits.

                  (i) CONTROLLING LAW. THIS AGREEMENT IS MADE UNDER, AND SHALL
BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE
APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED SOLELY THEREIN, WITHOUT GIVING
EFFECT TO PRINCIPLES OF CONFLICTS OF LAW.

                  (j) JURISDICTION AND PROCESS. In any action between or among

of the parties irrevocably consents to the exclusive jurisdiction and venue of

<PAGE>   61

                  (k) NON-EXCLUSIVITY. The rights and remedies of Acquiror
hereunder are not exclusive of or limited by any other rights or remedies which
Acquiror may have, whether at law, in equity, by contract or otherwise, all of
which shall be cumulative (and not alternative).

                  (l) BANKRUPTCY QUALIFICATION. Each representation or warranty
made in or pursuant to this Agreement regarding the enforceability of any
contract shall be qualified to the extent that such enforceability may be
effected by bankruptcy, insolvency and other similar laws or equitable
principles (but not those concerning fraudulent conveyance) generally affecting
creditors' rights and remedies.

                  (m) CONSTRUCTION. The parties hereto agree that any rule of
construction to the effect that ambiguities are to be resolved against the
drafting party shall not be applied in the construction or interpretation of
this Agreement. As used in this Agreement, the words "include" and "including"
and variations thereof, shall not be deemed to be terms of limitation, but
rather shall be deemed to be followed by the words "without limitation".

                  (n) ASSIGNMENT; BINDING EFFECT. Except as provided herein,
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by either of the parties hereto (whether by operation of law
or otherwise) without the prior written consent of the other party. Subject to
the preceding sentence, this Agreement shall be binding upon each of the
Stockholders and his, her or its heirs, successors and assigns, and shall inure
to the benefit of Acquiror and its successors and assigns. Without limiting any
of the restrictions set forth in Section 2 or elsewhere in this Agreement, this
Agreement shall be binding upon any Person to whom any Subject Securities are
transferred. Notwithstanding anything contained in this Agreement to the
contrary, nothing in this Agreement, expressed or implied, is intended to confer
on any Person other than the parties hereto or their respective heirs,
successors and assigns any rights, remedies, obligations or liabilities under or
by reason of this Agreement.

                  (o) SPECIFIC PERFORMANCE. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement was not performed in accordance with its specific terms or was
otherwise breached. It is accordingly agreed that Acquiror shall be entitled to
an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court of proper
jurisdiction, this being in addition to any other remedy to which Acquiror is
entitled at law or in equity.

                  (p) OTHER AGREEMENTS AND INDEPENDENCE OF OBLIGATIONS. Nothing
in this Agreement shall limit any of the rights or remedies of Acquiror or any
of the obligations of 


<PAGE>   62

the Stockholders under any other agreement. The covenants and obligations of the
Stockholders set forth in this Agreement shall be construed as independent of
any other agreement or arrangement between any or all of the Stockholders, on
the one hand, and the Company or Acquiror, on the other. The existence of any
claim or cause of action by any or all of the Stockholders against the Acquiror
or the Company shall not constitute a defense to the enforcement of any of such
covenants or obligations against any or all of the Stockholders.

                  (q) OBLIGATIONS OF STOCKHOLDERS; SIGNATURES OF ALL
STOCKHOLDERS NOT REQUIRED. The obligations of the Stockholders under this
Agreement shall be several and not joint. Each Stockholder agrees that the
failure of any other Stockholder listed on the signature page to execute and
deliver this Agreement shall not affect in any way the validity or
enforceability of this Agreement with respect to those Stockholders who have
executed this Agreement or the rights of Acquiror under this Agreement.

         The undersigned Stockholder of [Cardinal], a Delaware corporation (the

any other action, agreement or transaction that would, directly or indirectly,
result in a Company Takeover Event; and (C) against any action, agreement or

of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the

                        CARDINAL ACQUISITION CORPORATION

                              OFFICERS' CERTIFICATE


         The undersigned officers of NCO Group, Inc., a Pennsylvania business
corporation ("NCO"), and Cardinal Acquisition Corporation, a Delaware
corporation which is a wholly-owned subsidiary of NCO ("Sub"), in connection
with the legal opinions to be delivered by Blank Rome Comisky & McCauley LLP and
Katten Muchin & Zavis relating to an Agreement and Plan of Reorganization
("Reorganization Agreement") and related Agreement and Plan of Merger dated ,
1999 ("Plan of Merger") (the Reorganization Agreement and the Plan of Merger as
mentioned collectively referred to as the "Merger Agreement") by and between NCO
Group, Inc. and Compass International Services Corporation, incorporated under
the Delaware General Corporation Law, as amended ("Compass"), and recognizing
that Blank Rome Comisky & McCauley LLP and Katten Muchin & Zavis will rely on
this Certificate in delivering such opinions, hereby certify that the facts
which are described in this Certificate relating to the proposed merger
("Merger") of Sub with and into Compass pursuant to the Merger Agreement are
true, complete and correct in all respects as of the date hereof and will be
true, complete and correct in all respects on the Effective Date of the Merger
as set forth in the Merger Agreement1, and further certify as follows:

         1. I am familiar with the terms and provisions of the Merger Agreement
pursuant to which: (a) Sub will be merged with and into Compass, with Compass
surviving the Merger and (b) Compass shareholders will receive NCO Common Stock

--------

     1 All terms used and not defined herein shall have the meaning ascribed to
them in the Plan of Merger.


<PAGE>   68

pursuant to certain formula conversion ratios.

         2. As to the matters set forth below, I either have personal knowledge
or have obtained information from officers and employees of NCO and Sub, in whom
I have confidence and whose duties require them to have personal knowledge
thereof.

         3. I also have examined the Joint Proxy Statement/Prospectus (the
"Prospectus") of NCO and Compass dated on or about         , 1999 relating to 
the Merger (including the financial statements and exhibits that are a
part of or incorporated in the Prospectus), and to the best of my knowledge,
information and belief, the facts stated in or incorporated in the Prospectus
relating to NCO and Sub are true, correct and complete.

         4. To the best of my knowledge, the fair market value of the NCO Common
Stock to be received by each shareholder of Compass will be approximately equal
to the fair market value of the Compass stock surrendered in exchange therefor.

         5. Prior to the Merger, NCO will be in control of Sub within the
meaning of Section 368(c) of the Internal Revenue Code, as amended ("Code").

         6. Following the Reorganization, Compass will hold at least ninety
percent (90%) of the fair market value of its net assets and at least seventy
percent (70%) of the fair market value of its gross assets and at least ninety
percent (90%) of the fair market value of Sub's net assets and at least seventy
percent (70%) of the fair market value of Sub's gross assets held immediately
prior to the transaction. For purposes of this representation, amounts paid by
Compass or Sub to shareholders who receive cash or other property, amounts used
by Compass or Sub to pay reorganization expenses, and all redemptions and
distributions (except for regular, normal dividends) made by Compass will be
included as assets of Compass or Sub, respectively, immediately prior to the
transaction.

         7. Following the Merger, Compass will not issue additional shares of
its stock that would result in NCO losing control of Compass within the meaning
of Section 


<PAGE>   69

368(c) of the Code.

         8. NCO has no plan or intention to reacquire any of its stock to be
issued in the Merger.

         9. NCO has no plan or intention to liquidate Compass; to merge Compass
into another corporation; to sell or otherwise dispose of the stock of Compass;
or to cause Compass to sell or otherwise dispose any of the assets of Compass or
any of the assets acquired from Sub, except for dispositions made in the
ordinary course of business or transfers described in Section 368(a)(2)(C) of
the Code.

         10. Following the transaction, Compass will continue its historic
business or use a significant portion of Compass' business assets in a business.

         11. NCO, Sub, Compass, and the shareholders of Compass will each pay
their respective expenses, if any, incurred in connection with the Merger.

         12. There is no intercorporate indebtedness between NCO and Compass,
nor between Sub and Compass, that was issued, acquired, or will be settled at a
discount.

         13. Neither NCO nor Sub are "investment companies" as defined in
Sections 368(a)(2)(F)(iii) or (iv) of the Code.

         14. No Sub stock will be issued in the Merger.

         15. None of the compensation received by any shareholder-employees of
Compass was separate consideration for, or allocable to, any of their shares of
Compass Common Stock; none of the shares of NCO Common Stock received by any
shareholder-employees were separate consideration for, or allocable to, any
employment agreement; and the compensation paid to any stockholder-employees
will be for services actually rendered and will be commensurate with amounts
paid to third parties bargaining at arm's length for similar services.

         16. In the Merger, shares of Compass stock representing "control" of




<PAGE>   70


Compass, as defined under Section 368(c) of the Code, will be exchanged solely
for NCO stock. For purposes of this representation, Compass stock exchanged for
cash or other property furnished by NCO will be considered as acquired by NCO.
Further, no liabilities of Compass or the Compass shareholders will be assumed
by NCO, nor will any of the Compass stock be subject to any liabilities.

         17. NCO does not own, directly or indirectly, nor has it owned during
the past five (5) years, directly or indirectly, any Compass stock.

         18. Sub is either (i) a newly created subsidiary of NCO created for the
sole purpose of effectuating the Merger, or (ii) an existing subsidiary of NCO,
if the use of such subsidiary does not prevent the issuance of the legal
opinions described in the initial paragraph hereof.

Blank Rome Comisky & McCauley LLP

Philadelphia, PA 19103

Ladies and Gentlemen:

         We refer to the Agreement dated as of May 12, 1999 (the "Agreement")
among NCO Group, Inc., a Pennsylvania corporation ("Parent"), Cardinal
Acquisition Corporation, a Delaware corporation and a transitory wholly-owned
subsidiary of Parent ("Merger Sub"), and Compass International Services
Corporation, a Delaware corporation (the "Company"), which provides for the
merger (the "Merger") of Merger Sub with and into the Company on the terms and
conditions therein set forth, the time at which the Merger becomes effective
being hereinafter referred to as the "Effective Time." It is a condition to the
obligations of the Company to effect the Merger that Katten Muchin & Zavis,
counsel to Company, pursuant to Section 7.3(c) of the Agreement, and it is a
condition of the obligation of Parent and Merger Sub to effect the Merger that
Blank Rome Comisky & McCauley LLP, counsel to Parent and Merger Sub, pursuant to
Section 7.2(e) of the Agreement, render opinions to Company and Parent,
respectively, regarding certain United States federal income tax consequences of
the Merger. Capitalized terms not defined herein have the meanings specified in
the Agreement.

         In connection with such opinions to be rendered by each of you, and
acknowledging that each of you will rely upon the statements and representations
made in this letter, the Company hereby certifies and represents to each of you
that the statements and representations stated herein are true, correct and
complete in all respects at the date hereof and will be true, correct and
complete in all respects as of the Effective Time (as if made as of the
Effective Time).

                  1. The Company Common Stock is the only stock of the Company
         issued and outstanding. The fair market value of the Parent Common
         Stock and any cash in lieu of a fractional share of Parent Common Stock
         received by each Company stockholder will be approximately equal to the
         fair market value of the Company Common Stock surrendered in the
         exchange. In connection with the Merger, no holder of Company stock
         will receive in exchange for Company stock, directly or indirectly, any
         consideration from Parent other than Parent Common Stock and cash in
         lieu of a fractional share thereof.

Compass International Services Corporation
_______ __, 1999
Page 2

                  2.   At the Effective Time, the Company will hold at least 90%
         of the fair market value of its net assets and at least 70% of the fair
         market value of its gross assets held immediately prior to the
         Effective Time. For purposes of this representation, amounts used by
         the Company to pay Merger expenses, amounts paid by the Company to
         redeem stock, securities, warrants or options of the Company as part of
         any overall plan of which the Merger is part, and amounts distributed
         by the Company to stockholders of the Company (except for regular,
         normal dividends) as part of any overall plan of which the Merger is a
         part, in each case will be treated as constituting assets of the
         Company immediately prior to the Effective Time. Without limiting the
         foregoing, all proceeds that have been received from the sales of stock
         by the Company in connection with the Stock Purchase Agreement between
         the Company and Swiss-Irish Enterprises, dated May __ 1999, have been
         retained by the Company for use in its business.

                  3.   Prior to and in connection with the Merger, (i) the
         Company has not redeemed (and will not redeem) any Company stock and
         has not made (and will not make) any extraordinary distributions with
         respect thereto; and (ii) no person that is related to the Company
         within the meaning of Temp. Treas. Reg. ss. 1.368-1T(e)(2)(ii) has
         acquired (or will acquire) Company stock from any holder thereof.

                  4.   Any dispositions prior to the Merger, in contemplation or
         as part of the Merger, of assets held by the Company will be (or have
         been) for full fair market value.

                  5.   Each of the Company and its stockholders has paid and
         will pay only their respective expenses, if any, incurred in connection
         with the Merger, and the Company has not agreed to assume, nor will it
         directly or indirectly assume, any expense or other liability, whether
         fixed or contingent, of any holder of Company Common Stock.

                  6.   There is no intercorporate indebtedness currently
         existing between Parent and the Company or between Merger Sub and the
         Company that was issued, was acquired or was or will be settled at a
         discount.

                  7.   The Company has no plan or intention to issue additional
         shares of its stock after the Effective Time that would result in
         Parent losing control of the Company within the meaning of Section
         368(c) of the Code.

                  8.   At the Effective Time, the Company will not have
         outstanding any warrants, options, convertible securities, or any other
         type of right pursuant to which any person could acquire stock in the
         Company that, if exercised or converted, would affect Parent's
         acquisition or retention of control of the Company, as defined in
         Section 368(c) of the Code. Immediately prior to the Effective Time,
         other than options outstanding under the Company's Option Plan, there
         will be no options, warrants, equity securities, 


<PAGE>   73
Compass International Services Corporation

Page 3

         calls, rights, commitments or agreements of any character to which the
         Company or any of its subsidiaries is a party or by which it is bound
         obligating the Company or any of its subsidiaries to issue, deliver or
         sell, or cause to be issued, delivered or sold, additional shares of
         capital stock of the Company or any of its subsidiaries or obligating
         the Company or any of its subsidiaries to grant or enter into any such
         option, warrant, equity security, call, right, commitment or agreement.

                  9.   The Company is not an investment company, as defined in
         Sections 368(a)(2)(F)(iii) and (iv) of the Code.

                  10.   The Company is not under the jurisdiction of a court in
         a Title 11 or similar case within the meaning of Section 368(a)(3)(A)
         of the Code.

                  11.   At the Effective Time, the total fair market value of
         the assets of the Company will exceed the sum of its liabilities, plus
         (without duplication) the amount of any liabilities to which such
         assets are subject.

                  12.   None of the compensation to be received by any Company
         stockholder who is an employee of the Company or any affiliate of the
         Company at the Effective Time, whether for past or future services to
         the Company, will be separate consideration for, or allocable to, any
         of his or her shares of Company Common Stock.

                  13.   None of the Parent Common Stock to be received in the
         Merger by any Company stockholder who is an employee of the Company or
         an affiliate of the Company at the Effective Time in exchange for
         Company Common Stock will be separate consideration for, or allocable
         to, any employment arrangement.

                  14.   In the Merger, shares of Company stock representing
         control of the Company (within the meaning of Section 368(c) of the
         Code) will be exchanged solely for Parent Common Stock. No shares of
         Company Common Stock are, or at the Effective Time will be, held by any
         direct or indirect subsidiary of the Company. For purposes of this
         paragraph 15, shares of Company stock to be exchanged for cash or other
         property originating with Parent are treated as constituting
         outstanding shares of the Company stock at the Effective Time.

                  15.   Following the Merger, the Company will continue its
         historic business or use a significant portion of its business assets
         in a business.

                  16.   The payment of cash in lieu of fractional shares of
         Parent Common Stock is solely for the purposes of avoiding the expense
         and inconvenience to Parent of issuing fractional shares and does not
         represent separately bargained-for consideration. The total 

<PAGE>   74

Page 4

         cash consideration that will be paid in the Merger to the holders of
         Company Capital Stock in lieu of issuing fractional shares of Parent
         Common Stock will not exceed 1% of the total consideration that will be
         issued in the Merger to the holders of the Company Common Stock in
         exchange for their Company Common Stock. Except for any cases in which
         a Company stockholder holds a beneficial interest in shares of Company
         Common Stock through more than one account and such multiple accounts
         cannot be aggregated by the Company, either because the beneficial
         interests cannot be identified by the Company or it would be
         impracticable for the Company to do so, the fractional share interests
         of each Company stockholder will be aggregated, and no Company
         stockholder will receive an amount of cash greater than the Share
         Value.

                  17.   At the Effective Time of the Merger, there will be no
         accrued but unpaid dividends on Company Common Stock.

         The Company hereby undertakes to inform each of you and Parent
immediately should any of the foregoing statements or representations become
untrue, incorrect or incomplete in any respect on or prior to the Effective
Time. This letter is being furnished to each of you solely for your benefit and
for use in rendering your opinions and is not to be used, circulated, quoted or
otherwise referred to for any other purpose (other than as referred to or
included in your opinions) without the express written consent of the Company.

                                            Very truly yours,

         RE:      ACQUISITION OF COMPASS INTERNATIONAL SERVICES CORPORATION
                  ---------------------------------------------------------

Gentlemen:

         You have requested our opinion concerning certain Federal income tax
consequences of the merger of Cardinal Acquisition Corporation, an entity
incorporated under the Delaware Corporation Law, as amended ("Sub"), and a
wholly-owned subsidiary of NCO Group, Inc., a Pennsylvania business corporation,
("Parent"), with and into Compass International Services Corporation, an entity
incorporated under the Delaware Corporation Law ("Compass"). The terms of the
merger are described in the Joint Proxy Statement/ Prospectus of Parent dated
                  , 1999 (the "Prospectus"). Our opinion is based upon our
understanding of the facts of and incident to the transaction, as are set forth
in the Prospectus, and upon the condition that those facts are true, correct and
complete. Further, our opinion is issued in reliance upon the Officer's

         In connection with our opinion, we have examined and are familiar with
originals or copies, certified or otherwise identified to our satisfaction, of
the Plan of Merger, the Prospectus and such other documents as we have deemed
necessary or appropriate as a basis for the opinions set forth below. In our
examination we have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as originals, the conformity to original
documents of all documents submitted to us as certified or photostatic copies
and the authenticity of the originals of such latter documents. As to any facts
material to this opinion which we did not independently establish or verify, we
have relied upon statements and representations of officers and other
representatives of Parent, Sub, Compass and others. In particular, we have
relied upon certain representations of the managements of Parent, Sub and
Compass in the Officer's Certificates which are attached hereto.

         In rendering our opinion, we have considered the applicable provisions
of the Internal Revenue Code of 1986 as amended (the "Code")1, Treasury
Regulations and the pertinent judicial authorities and interpretive rulings of
the Internal Revenue Service (the "Service").

         Based solely upon the foregoing and provided that the Merger and the
other transactions contemplated by the Plan of Merger are consummated in the
manner described in the Prospectus, we are of the opinion that under present
law, for federal income tax purposes:

                  1. The Merger of Sub into Compass will constitute a
reorganization within the meaning of Section 368(a) of the Code. Parent, Sub and
Compass each will be "a party to a reorganization" within the meaning of Section
368(b) of the Code.

                  2. Compass shareholders will recognize no gain or loss upon
their exchange of Compass stock for shares of Parent Common Stock. Code Section
354(a).

Code.

                  3. The basis of the Parent Common Stock received by the
shareholders of Compass (including fractional shares) will be the same as the
basis of the Compass stock surrendered in exchange. Code Section 358(a)(1).

                  4. The holding period of the Parent Common Stock received by a
Compass shareholder (including any fractional shares) will include the period
during which the Compass stock surrendered in exchange therefor was held by such
Compass shareholder, provided that the Compass stock surrendered was a capital
asset in the hands of such Compass shareholder on the date of the exchange. Code
Section 1223(a).

                  5. Cash received by shareholders of Compass in lieu of
fractional shares of Parent will be treated as a distribution in redemption of
their fractional share interests subject to the provisions and limitations of
Section 302 of the Code. Rev.
Rul. 66-365, 1966-2 C.B. 116.

         This letter expresses our views only as to the specific issues
addressed above. No opinion is expressed concerning the Federal income tax
treatment of the transaction under any provision of the Code not specifically
referenced herein, including the tax treatment of the substitution by Parent of
any options to purchase Compass Common Stock. No opinion is expressed with
respect to state and local taxes, Federal or state securities law, or any other
Federal, state or local law not expressly referenced herein.

         Our opinions set forth our legal judgement, and are not binding on the
Service or any other person. Therefore, there can be no assurance that the
conclusions set forth herein would be sustained by a court if challenged.

         Further, the opinions set forth represent our conclusions based upon
the documents reviewed by us and the facts presented to us. Any material
amendments to such documents or changes in any significant fact could affect the
opinions expressed herein.

         We are pleased to offer this opinion based upon the Federal income tax
laws

                                                   ______, 1999

Compass International Services Corporation
Attention:  Board of Directors

Ladies and Gentlemen:

         We have been requested to render this opinion concerning certain
matters of federal income tax law in connection with the proposed merger of
Cardinal Acquisition Corporation, a newly formed corporation, organized and
existing under the laws of the State of Delaware ("Merger Sub") which is wholly
owned by NCO Group, Inc., a corporation organized and existing under the laws of
the State of Pennsylvania ("Parent"), with and into Compass International
Services Corporation, a corporation organized and existing under the laws of the
State of Delaware (the "Company"), with the Company surviving the merger and
becoming a wholly owned subsidiary of Parent, pursuant to the applicable
corporate law of the State of Delaware (the "Merger"), and in accordance with
that certain Agreement and Plan of Merger dated as of May 12, 1999, among the
Company, Parent and Merger Sub (the "Agreement") and related documents and
agreements referenced in the Agreement (together with the Agreement, the "Merger
Agreement"). Our opinion is being delivered to you pursuant to Section 7.3(c) of
the Agreement.

         Except as otherwise provided, capitalized terms referred to herein have
the meanings set forth in the Merger Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

         We have acted as special legal counsel to the Company in connection
with the Merger. As such, and for the purpose of rendering this opinion, we have
examined (or will examine on or prior to the Effective Time of the Merger) and
are relying (or will rely) upon (without any independent investigation or review
thereof) the truth and accuracy, at all relevant times, of the statements,
covenants, representations and warranties contained in the following documents

         3.       Representations made to us by Parent and Merger Sub, including
                  those representations contained in that certain Parent Tax
                  Certificate dated _____;

         4.       Representations made to us by the Company, including those
                  representations contained in that certain Company Tax

                  organization and operation of the Company, Parent and Merger
                  Sub or the consummation of the Merger and the transactions
                  contemplated by the Merger Agreement as we have deemed
                  necessary or appropriate.

         In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

         1.       Original documents (including signatures) are authentic;
                  documents submitted to us as copies conform to the original
                  documents, and there has been (or will be by the Effective
                  Time of the Merger) due execution and delivery of all
                  documents where due execution and delivery are prerequisites
                  to the effectiveness thereof;

         2.       Any representation or statement referred to above made "to the
                  knowledge of" or otherwise similarly qualified is correct
                  without such qualification;

         3.       The Merger will be consummated pursuant to the Merger
                  Agreement and will be effective under the applicable state
                  law;

         4.       After the Merger, the Company will hold "substantially all" of
                  its and Merger Sub's properties within the meaning of Section
                  368(a)(2)(E)(i) of the Code and the regulations promulgated
                  thereunder;

         5.       Following the Merger, the Company will continue its historic
                  business or use a significant portion of its historic business
                  assets in a business;

         6.       No outstanding indebtedness of the Company, Parent or Merger
                  Sub has represented or will represent equity for tax purposes
                  (including, without limitation, any loans from Parent to the
                  Company); no outstanding equity of the Company, Parent or
                  Merger Sub has represented or will represent indebtedness for
                  tax purposes; no outstanding security (other than the Company
                  Option Plan),

                  instrument, agreement or arrangement that provides for,
                  contains, or represents either a right to acquire the Company
                  stock or to share in the appreciation thereof constitutes or
                  will constitute "stock" for purposes of Section 368(c) of the
                  Code; 

         7.       Each of Company, Parent and Merger Sub has paid and will pay
                  only its respective expenses, if any, incurred in connection
                  with the Merger, and neither Parent, Merger Sub nor Company
                  has agreed to assume, nor will it directly or indirectly
                  assume, any expense or other liability, whether fixed or
                  contingent, of any holder of Common Stock; and

         8.       Neither Parent, the Company nor Merger Sub is, or will be at
                  the time of the Merger: (a) an "investment company" within the
                  meaning of Section 368(a)(2)(F) of the Code; or (b) under the
                  jurisdiction of a court in a Title 11 or similar case within
                  the meaning of Section 368(a)(3)(A) of the Code.

         Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, it is
our opinion, as special counsel for Company, that for federal income tax
purposes:

                  (i)      the Merger will constitute a "reorganization" within
                           the meaning of Section 368(a) of the Code, and the
                           Company, Merger Sub and Parent will each be a party
                           to such reorganization within the meaning of Section
                           368(b) of the Code;

                  (ii)     no gain or loss will be recognized by Company,
                           Parent, or Merger Sub as a result of the Merger;

                  (iii)    no gain or loss will be recognized by the
                           stockholders of the Company upon the exchange of
                           their Common Stock solely for shares of Parent Common
                           Stock pursuant to the Merger, except with respect to
                           cash, if any, received in lieu of fractional shares
                           of Parent Common Stock;

                  (iv)     the aggregate tax basis of the shares of Parent
                           Common Stock received solely in exchange for Common
                           Stock pursuant to the Merger (including fractional
                           shares of Parent Common Stock for which cash is
                           received) will be the same as the aggregate tax basis
                           of the Common Stock exchanged therefor;
<PAGE>   82
_____, 1999
Page 4

                  (v)      the holding period for shares of Parent Common Stock
                           received solely in exchange for Common Stock pursuant
                           to the Merger will include the holding period of the
                           Common Stock exchanged therefor, provided such Common
                           Stock was held as a capital asset by the stockholder
                           at the Effective Time; and

                  (vi)     a stockholder of the Company who receives cash in
                           lieu of a fractional share of Parent Common Stock
                           will recognize gain or loss equal to the difference,
                           if any, between such stockholder's tax basis in such
                           fractional share (as described in clause (iv) above)
                           and the amount of cash received.

         In addition to the assumptions set forth above, this opinion is subject
to the exceptions, limitations and qualifications set forth below:

         1.       This opinion represents and is based upon our best judgment
                  regarding the application of federal income tax laws arising
                  under the Code, existing judicial decisions, administrative
                  regulations and published rulings and procedures. Our opinion
                  is not binding upon the Internal Revenue Service or the
                  courts, and the Internal Revenue Service is not precluded from
                  asserting a contrary position. Furthermore, no assurance can
                  be given that future legislative, judicial or administrative
                  changes, on either a prospective or retroactive basis, would
                  not adversely affect the accuracy of the opinion expressed
                  herein. Nevertheless, we undertake no responsibility to advise
                  you of any new developments in the application or
                  interpretation of the federal income tax laws.

         2.       Our opinion concerning certain of the federal tax consequences
                  of the Merger is limited to the specific federal tax
                  consequences presented above. No opinion is expressed as to
                  any transaction other than the Merger, including any
                  transaction undertaken in connection with the Merger. In
                  addition, this opinion does not address any other federal,
                  estate, gift, state, local or foreign tax consequences that
                  may result from the Merger.

         3.       No opinion is expressed if all the transactions described in
                  the Merger Agreement are not consummated in accordance with
                  the terms of such Merger Agreement and without waiver or
                  breach of any material provision thereof or if all of the
                  representations, warranties, statements and assumptions upon
                  which we relied are not true and accurate at all relevant
                  times. In the event any one of the statements,
                  representations, warranties or assumptions upon which we have
                  relied to issue this 

<PAGE>   83
_____, 1999
Page 5

                  opinion is incorrect, our opinion might be adversely affected
                  and may not be relied upon.

         4.       No ruling has been or will be requested from the Internal
                  Revenue Service concerning the federal income tax consequences
                  of the Merger. In reviewing this opinion, you should be aware
                  that the opinion set forth above represents our conclusions
                  regarding the application of existing federal income tax law
                  to the instant transaction. If the facts vary from those
                  relied upon (including if any representation, covenant,
                  warranty or assumption upon which we have relied is
                  inaccurate, incomplete, breached or ineffective), our opinion
                  contained herein could be inapplicable. You should be aware
                  that an opinion of counsel represents only counsel's best
                  legal judgment, and has no binding effect or official status
                  of any kind, and that no assurance can be given that contrary
                  positions will not be taken by the Internal Revenue Service or
                  that a court considering the issues would not hold otherwise.

         5.       This opinion is being delivered solely for the purpose of
                  satisfying the condition set forth in Section 7.3(c) of the
                  Merger Agreement. This opinion may not be relied upon or
                  utilized for any other purpose or by any other person or
                  entity, including the Company and its stockholders, and may
                  not be made available to any other person or entity, without
                  our prior written consent. We do, however, consent to the use
                  of our name in the Registration Statement wherever it appears.


                                                     Very truly yours,


                                                     KATTEN MUCHIN & ZAVIS
