following representations and warranties to Buyer:

the Exchange Act, the Securities Act or the New York Stock Exchange, Inc., (ii)
filings required under the securities or blue sky laws of the various states,

         4.7 RECORDS OF FHPS. The copies of the certificates of incorporation
and bylaws of FHPS and the agreements of FHPS and IPS which were provided to
Buyer are true, accurate, and complete and reflect all amendments made through
the date of this Agreement. The minute books and other records of corporate
actions for FHPS made available to Buyer for review were correct and complete
as of the date of such review, no further entries have been made through the
date of this Agreement, such minute books and records contain the true
signatures of the persons purporting to have signed them, and such minute books
and records contain an accurate record of all corporate actions of the
stockholders and directors (and any committees thereof) of FHPS taken by
written consent or at a meeting since formation. All corporate actions taken by
FHPS have been duly authorized or ratified. All accounts, books, ledgers and
official and other records of FHPS have been fully, properly and accurately
kept and are complete, and there are no material inaccuracies or discrepancies
contained therein. The stock ledgers of FHPS, as previously made available to
Buyer, contain accurate and complete records of all issuances, transfers and
cancellations of shares of the capital stock of FHPS. To the Company Parties'
knowledge, the books and all corporate (including minute books and stock record

Statements do not reflect any writeup or revaluation increasing the book value
of any assets, except as specifically disclosed in the notes thereto or as
otherwise disclosed in writing to Buyer. All financial projections, forecasts,

         4.12 ENVIRONMENTAL MATTERS. Except as set forth on Schedule 4.12:

              (a) During the period commencing from the date in 1991 on which 
FHPS became a wholly owned subsidiary of the Company to the date of this

Federal, state and local environmental protection, health and safety or similar

failure to be so in compliance would not result in a Material Adverse Effect on
FHPS.

                  (b) During the period commencing from the date in 1991 on
which FHPS became a wholly owned subsidiary of the Company to the date of this
Agreement, FHPS has not received any written notice from any Governmental
Authority or other third party or, to the knowledge of the Company Parties, any
other communication alleging or concerning any violation by FHPS, or
responsibility for or liability of FHPS under any Environmental Law, which, if
decided unfavorably to FHPS would have a Material Adverse Effect on FHPS or the
Purchased Assets. There are no pending, or to the knowledge of the Company
Parties, threatened, claims, suits, actions, proceedings or investigations with
respect to the businesses or operations of FHPS alleging or concerning any
violation of or responsibility for or liability under any Environmental Law,
nor does any Company Party have any knowledge of any fact or condition that
could give rise to such a claim, suit, action, proceeding or investigation
which, if decided unfavorably to FHPS would have a Material Adverse Effect on
FHPS or the Purchased Assets.

         4.13 REAL ESTATE. FHPS does not currently own any real property.
Schedule 4.13 sets forth a list of all leases, licenses or similar use or
occupancy agreements to which FHPS is a party, which are for the use or

forth: (i) the lessor and lessee thereof and the commencement date, term and
renewal rights under each of the Leases; and (ii) the street address or legal
description of each property covered thereby (the "LEASED PREMISES"). The
Leases are in full force and effect and have not been amended except as
disclosed in Schedule 4.13, and there have been no notices of default by either
party to the Leases. With respect to each such Leased Premises: (i) FHPS'
interests in the Leased Premises are free and clear of any Liens, covenants and
easements or title defects created or suffered to be created by FHPS, except
for Liens for taxes which are not yet due or are otherwise being contested; and
(ii) none of the Company Parties has received notice of (A) any condemnation
proceeding with respect to any portion of the Leased Premises or any access
thereto and, to the knowledge of the Company Parties, no such proceeding is
contemplated by any Governmental Authority; or (B) any special assessment which
may affect any of the Leased Premises and, to the knowledge of the Company
Parties, no such special assessment is contemplated by any Governmental
Authority, any of which would have a Material Adverse Effect on FHPS.

         4.14 COMPLIANCE WITH LAWS. Except as set forth on Schedule 4.14, FHPS
is in substantial compliance with all laws, regulations and orders applicable
to it, its business, operations, properties and assets, except where the
failure to comply would not have a Material Adverse Effect on FHPS or the
Purchased Assets. During the period commencing from when FHPS became a wholly
owned subsidiary of the Company in 1991 to the date of this Agreement, FHPS has
not been cited, fined or otherwise notified of any asserted past or present
failure to comply with any laws, regulations or orders, where there remains any
remedial action to be undertaken by FHPS as a result thereof, and no proceeding
with respect to any such violation is pending or to the Company Parties'
knowledge threatened. Except as set forth on Schedule 4.14, 


<PAGE>   15



FHPS is not subject to any decree or injunction to which it is a party which
restricts the continued operation of its business or the expansion thereof to
other geographical areas, customers and suppliers or lines of business, which
decree or injunction has a Material Adverse Effect on FHPS.

         4.15 LABOR AND EMPLOYMENT MATTERS. FHPS is not a party to or bound by
any collective bargaining agreement or any other agreement with a labor union.
There is not now any actual or threatened labor dispute, strike or work
stoppage which affects or which may affect the business of FHPS or which may
interfere with its continued operations. Except as set forth on Schedule 4.15,
none of the Company Parties is aware that any executive or key employee or
group of employees of FHPS or IPS has any plans to terminate his, her or their
employment with FHPS or IPS as a result of the transactions contemplated hereby

the most recent annual reports on Form 5500 and summary plan descriptions with
respect thereto, were furnished to Buyer).

                  (b) Compliance with Law. With respect to each Employee
Benefit Plan to the best knowledge of the Company Parties: (i) each has been

406 of ERISA or Section 4975 of the Code, except where the failure of any of

Section 4980B of the Code or Sections 601 through 608 of ERISA have occurred

"change of control" (as such term is defined in Section 280G of the Code); and
(ii) none of the Employee Benefit Plans has any unfunded liabilities which are
not reflected on the Current Balance Sheet or the books and records of FHPS.

         4.17 INSURANCE. FHPS and the Purchased Assets are covered by policies
of insurance for its properties, assets and businesses (the "INSURANCE
POLICIES"), which policies are in full force and effect, and which coverage
amounts are adequate for the business conducted by FHPS and the Purchased
Assets, and all premiums due thereon have been paid. Prior to the Closing Date,
each of the Insurance Policies will be in full force and effect. FHPS has
complied with the provisions of such Insurance Policies, except where the
failure to comply would not have a Material Adverse Effect on FHPS. There is no
pending claim under any of the Insurance Policies for an amount in excess of
$10,000 individually or $50,000 in the aggregate that relates to loss or damage
to the properties, assets or business of FHPS.

         4.18 RECEIVABLES. All of the Receivables of FHPS, net of any allowance
for doubtful accounts reflected in the Current Balance Sheet, are valid and
legally binding, represent bona fide transactions and arose in the ordinary
course of business of FHPS. To the best of the Company Parties' knowledge, all
of the Receivables of FHPS reflected in each Current Balance Sheet are
collectible in accordance with the terms of such receivables, without set off
or counterclaims, subject to the allowance for doubtful accounts, if any, set
forth on such Current Balance Sheet. For purposes of this Agreement, the term
"RECEIVABLES" means all receivables of FHPS, including without limitation,
trade account receivables arising from the provision of services, sale of
inventory, notes receivable, and insurance proceeds receivable, whether or not
billed.

         4.19 LICENSES AND PERMITS. There are no licenses and governmental or
official approvals, permits or authorizations required for the conduct of FHPS'
business and operations, the absence of which would have a Material Adverse
Effect on FHPS (collectively, the "FHPS 


<PAGE>   17



PERMITS"). All FHPS Permits are valid and in full force and effect, FHPS is in
compliance with the respective requirements thereof, no proceeding is pending
or, to the Company Parties' knowledge, threatened to revoke or amend any of
them, and none of the FHPS Permits is or will be impaired or affected, which
impairment or affect would have a Material Adverse Effect on FHPS, by the
execution and delivery of this Agreement or the consummation of the
transactions contemplated hereby, except for such of the preceding which,
individually or in the aggregate, would not have a Material Adverse Effect on
FHPS or on the ability of the parties to consummate the transactions
contemplated herein.

         4.20 ADEQUACY OF THE ASSETS; RELATIONSHIPS WITH CUSTOMERS AND
SUPPLIERS; AFFILIATED TRANSACTIONS. Except as set forth on Schedule 4.20, the
Purchased Assets, including Purchased Assets held by IPS, and assets and
properties currently owned and operated by FHPS constitute, in the aggregate,
all of the assets and properties used in the conduct of the business of FHPS
and IPS, with respect to the Purchased Assets, in the manner in which and to
the extent to which such business is currently being conducted. Neither FHPS,
nor, with respect to the Purchase Assets, IPS, has received any notice from any
current supplier of items essential to the conduct of its business that such
supplier intends to terminate or materially alter a business relationship with
FHPS or, with respect to the Purchased Assets, IPS, for any reason, involving
an amount in excess of $50,000, and to the Company Parties' knowledge, no such
supplier intends to terminate or materially alter any such business
relationship with FHPS, or IPS. Neither FHPS nor IPS has received any notice
from any customer that such customer intends to discontinue purchases of
products or services from FHPS, or, in connection with the Purchased Assets,
IPS, and to the Company Parties' knowledge no such customer intends to
discontinue or cancel purchases or orders, involving in each case amounts in
excess of $50,000. No Company Party has any direct or indirect interest in any
customer, supplier or competitor of FHPS or in any Person from whom FHPS leases
real or personal property, except to the extent that any such customer,
supplier or competitor is also an Affiliate of the Company, or except for any
passive investment interest held by any of the Company Parties.

         4.21 INTELLECTUAL PROPERTY. Except as set forth in Schedule 4.21, FHPS
has full legal right, title and interest in and to all trademarks, service
marks, trade names, copyrights, know-how, patents, trade secrets, licenses
(including licenses for the use of computer software programs), and other
intellectual property used in the conduct of its business (the "INTELLECTUAL
PROPERTY"), the absence of which would have a Material Adverse Effect on FHPS
or the Purchased Assets. Schedule 4.21 sets forth a true and correct list of
all Intellectual Property of FHPS. To the Company Parties' knowledge, FHPS owns
or possesses adequate rights to use all Intellectual Property reasonably
necessary to the conduct of the business of FHPS as presently conducted, and
the unrestricted conduct and the unrestricted use and exploitation of the
Intellectual Property does not infringe or misappropriate any rights held or
asserted by any Person, except where the failure to possess such rights or the
infringement would not have a Material Adverse Effect on FHPS or the Purchased
Assets. To the Company Parties' knowledge, no Person is infringing on the
Intellectual Property, and no payments are required for the continued use of
the Intellectual Property, except for software licenses entered into in the
ordinary course of business. None of the Intellectual Property has ever been
declared invalid or unenforceable, or is the subject of any pending or, to the
Company Parties' knowledge, threatened action for opposition, cancellation,
declaration, infringement, or invalidity, unenforceability or misappropriation
or like claim, action or proceeding, which declaration or unenforceability, or
which pending or threatened action would have a Material Adverse Effect on FHPS
if decided adversely to FHPS.

         4.22 MATERIAL CONTRACTS. Schedule 4.22 sets forth a list of each
Material Contract of each Subsidiary, including all material contracts with
customers for the provision of products or services by each Subsidiary, other
than any Material Contract relating to any excluded assets or liabilities (the
"PURCHASED MATERIAL CONTRACTS"). The copy of each Material Contract furnished
to Buyer is a true and complete copy of the document it purports to represent
and reflects all amendments thereto made through the date of this Agreement.
Neither Subsidiary has violated any of the terms or conditions of any Purchased
Material Contract which would permit termination or material modification of
any Purchased Material Contract. All of the material covenants to be performed
by each Subsidiary and, to the knowledge of the Company Parties, any other
party thereto, have been fully performed in all material respects, and neither
Subsidiary has received notice for breach or indemnification or notice of
default or termination under any Purchased Material Contract by or against FHPS
or IPS or to the knowledge of the Company Parties, any other party thereto. To
the knowledge of the Company Parties, no event has occurred which constitutes,
or after notice or the passage of time, or both, would constitute, a default by
either Subsidiary under any Purchased Material Contract, and to the knowledge
of the Company Parties no such event has occurred which constitutes or would
constitute a material default by any other party. Neither Subsidiary is subject
to any liability or payment resulting from re-negotiation of amounts paid under
any Purchased Material Contract. As used in this Section 4.22, Purchased
Material Contracts shall mean formal or informal, written or oral (a) loan
agreements, indentures, mortgages, pledges, hypothecations, deeds of trust,
conditional sale or title retention agreements, security agreements, equipment
financing obligations or guaranties, or other sources of contingent liability
in respect of any indebtedness or obligations to any other Person, or letters
of intent or commitment letters with respect to same, which exceed $10,000
individually or $50,000 in the aggregate; (b) contracts obligating FHPS or IPS
to provide products or services for a period of one year or more; (c) leases of
real property extending for a period of one year or more; (d) leases of

independent contractor's services, or letters of intent with respect to same,
where the payment due thereunder exceeds $10,000; (f) employment agreements,
management service agreements, consulting agreements, having a value in the
form of revenue or expense in excess of $10,000; (g) any contract relating to
pending capital expenditures by FHPS in excess of $10,000; (h) contracts
obligating FHPS to purchase supplies, equipment, media and related services of
any kind, in an amount exceeding $10,000 and not cancelable without penalty on
notice of thirty (30) days or less; (i) any non-competition agreements
restricting FHPS in any manner; and (j) confidentiality agreements,
non-competition agreements, employee handbooks, policy statements and any other
agreements relating to any employee of FHPS, which is not terminable as of the
Closing.

various Schedules attached hereto) or any agreement executed in connection

governmental official, employee or agent where either the payment or the
purpose of such contribution, payment or gift was or is illegal under the laws
of the United States or any state thereof, or any other jurisdiction (foreign
or domestic); or (b) any contribution, or reimbursement of any political gift
or contribution made by any other Person, to candidates for public office,
whether federal, state, local or foreign, where such contributions by FHPS were
or would be a violation of applicable law.

         4.26 TAX MATTERS. Within the times (including extensions) and in the
manner prescribed by law, FHPS (or the Company, on behalf of FHPS) has filed
all federal, state, local and foreign returns for Taxes ("RETURNS") required to
be filed in any jurisdiction (including, without limitation, informational
returns) and such Returns are complete, true and correct in all material
respects. All Returns complied in all material respects with the tax laws,
rules and regulations, as presently interpreted, applicable to such Returns.
FHPS (or the Company on behalf of FHPS) has not waived or extended any statute
of limitations relating to the assessment of any Taxes. No audit or examination
of any of the Returns of FHPS is currently in progress or, to the Company
Parties' knowledge, threatened or has occurred in the past. All Taxes required

respective due dates, including any extensions thereof.

there is no reasonable basis for such position.

                  (c) Tax Cooperation. The Company and Buyer shall provide the
other party with such forms, information and records and make such of its
officers, directors, employees and agents available as may be reasonably

Closing Date shall be apportioned to the period ending after the Closing Date,
and (z) franchise and other privilege taxes not measured by income shall be

all claims for refunds relating to such Taxes; provided, however, that Buyer
shall not be required to file such claims for refund to the extent such claim
for refund would have a Material Adverse Effect on Buyer or FHPS in the future,
or to the extent such claims for refund relate to a carryback of an item. Buyer
shall be entitled to all other refunds and credits of Taxes; provided, however,
Buyer will not allow the amendment of any Tax Return relating to any Taxes for
a period (or portion thereof) ending on or prior to the Closing Date or the
carryback of an item to a period ending on or prior to Closing without the
Company's consent.

                  (g) Consent. Whenever any taxing authority asserts a claim,
makes an assessment or otherwise disputes the amount of taxes for which the
Company is or may be liable under this Agreement, Buyer shall, if informed of
such assertion, promptly inform the Company within fifteen business days, and
the Company shall have the right to control the resulting proceedings and to
determine whether and when to settle any such claim, assessment or dispute to
the extent such proceedings or determinations affect the amount of taxes for
which the Company may be liable under this Agreement. Whenever any taxing
authority asserts a claim, makes an assessment, or otherwise disputes the

                  (c) Transition of the Non-affiliated Business.

                           (i) The Company agrees that, following the Closing
         and until such time as the claims processing services are implemented
         by Buyer for each plan, the Company shall continue to perform the same
         scope of claims processing services that it provided for each such
         plan prior to the Closing. The Company shall use its reasonable best
         efforts to ensure that during this transition period such services are
         performed in such a manner that is consistent with the ordinary course
         of business immediately prior to Closing in order to preserve and keep
         intact the business relationships with such plans.

                           (ii) The Company and IPS agree that following the
         Closing and until such time as the FHS Affiliated Business has been

         (as contemplated by the Service Agreement), upon the request of Buyer,
         the Company and IPS shall cause the Non-affiliated Business to be
         eligible for rebates under any or all of the existing IPS rebate
         agreements should Buyer determine in its sole discretion that it
         desires to continue to use such agreements for the Non-affiliated
         Business. The Company and IPS agree that such rebates will be serviced
         in accordance with Buyer's instructions. IPS agrees that all rebates
         collected by IPS based on the utilization of the Non-affiliated
         Business prior to Closing shall be paid by IPS following Closing
         pursuant to the terms and conditions of the respective agreements for
         the Non-affiliated Business, and that Advance Paradigm's obligation to
         pay such rebates on such business shall begin with the rebates
         collected for the quarter ending June 30, 1999.

                           (iii) Upon Closing, subject to the respective
         agreements between Buyer and each plan covered by the Non-affiliated
         Business, mail pharmacy services shall be provided for the
         Non-Affiliated Business as determined by Buyer in its sole discretion.

                  (d) Pharmacy Network Agreements. Pursuant to the transactions
contemplated by this Agreement, IPS will assign to FHPS prior to Closing or
directly to Buyer as of the Closing, and Buyer will acquire, all of the retail
pharmacy network contracts held by IPS, including, but not limited to those set
forth on Schedule 4.22, and Buyer will assume all of the rights and obligations
thereunder upon Closing, or as soon thereafter as is practical; provided,
however, that the parties may agree to substitute new agreements between Buyer
and any such pharmacies in lieu of assignment of any such agreements. In
addition, the parties will use their reasonable best efforts to obtain
assignments of all other retail pharmacy network agreements, subject to any
limitations imposed under applicable law or regulation affecting any of the
Company's Affiliates. Subject to the respective agreements between Buyer and
each plan covered by the Non-affiliated Business, the pharmacy eligible
participants covered by such plans will continue to receive their prescription
services from such retail pharmacies. The parties will 



<PAGE>   25



use their reasonable best efforts to obtain a release of IPS and/or FHS from
any liability arising from any such pharmacy network agreements from and after
the Closing. In the event Buyer has failed or is otherwise unable to pay any
such pharmacies in accordance with such agreements (a "DEFAULT IN PHARMACY
PAYMENT"), upon written notice to Buyer and confirmation from Buyer's chief
financial officer that such amounts have not been paid to the pharmacies or to
the pharmacies' Affiliates or designees, FHS, or an FHS Affiliated Plan may
make payment in order to remedy any such Default in Pharmacy Payment, and FHS
shall have the right to offset any amounts that would have been due to Buyer
for such claims under the Service Agreement for such claims.

         5.13 CONDUCT OF COMPANY PENDING TRANSITION. From and after the date
hereof and prior to the complete transition of the Affiliated Business and the
Non-affiliated Business, unless Buyer shall otherwise agree in writing, and
except as otherwise expressly contemplated by this Agreement, each of the
Company and the Subsidiaries consents and agrees that the businesses of FHPS
and the business relating to the Purchased Assets shall be conducted only in,
and each of the Company and the Subsidiaries shall not take any action
affecting FHPS or the Purchased Assets except in, the ordinary course of
business and consistent with past practices, and each of the Company and the
Subsidiaries shall use its best efforts to maintain and preserve the business
organization, assets, employees and advantageous business relationships of FHPS
and the Purchased Assets.

         5.14 RESTRICTIVE COVENANTS.

                  (a) In order to assure that Buyer will realize the benefits
of the transactions contemplated hereby, subject to the Company's right to
terminate the Service Agreement after five (5) years, during the term of the
Service Agreement, but in any event not less than the five-year period
following the Closing Date, the Company and its Affiliates shall not engage in
pharmacy claims processing, retail pharmacy network management, mail service
pharmacy, rebate management or (subject to Section 3 of the Service Agreement)
the negotiation and performance of drug manufacturer agreements.
Notwithstanding the foregoing, (i) if the parties' obligations regarding
formulary management and drug manufacturer agreements are terminated in
accordance with Section 11(c)(i) of the Service Agreement, then, so long as the
Company complies with Section 11(c)(i) of the Service Agreement, the Company
may thereafter provide such services for the FHS Affiliated Members; and (ii)
if the Company releases Buyer from its obligations to perform the retail
pharmacy network management services in accordance with Section 11(c)(ii) of
the Service Agreement, then, so long as the Company is in compliance with
Section 11(c)(ii) of the Service Agreement, the Company may thereafter provide
such services for the FHS Affiliated Members; both (i) and (ii) including
participation (which may include minority ownership interests representing not
more than twenty percent (20%) of the equity or voting control) in cooperative
groups or alliances, provided the Company shall not market such services to
third parties. This section shall not be deemed to be a limitation on providing
clinical services (including pharmacy formulary and rebate management services
in accordance with Section 3 of the Service Agreement) to the FHS Affiliated
Members and the Company's contracting medical groups, or the disease management
services offered by the Company, or otherwise limit the Company or any
Affiliate from undertaking activities relating to the processing and payment of
medical claims generally as a payor of such claims.



<PAGE>   26



                  (b) Section 5.14(a) shall not be deemed to be a limitation on
providing clinical services (including pharmacy formulary and rebate management
services in accordance with Section 3 of the Services Agreement) to the
Affiliated Business and the Company's contracting medical groups, or the
disease management services offered by the Company, or otherwise limit the
Company or any Affiliate from undertaking activities relating to the processing
and payment of medical claims generally as a payor of such claims.

                  (c) Nothing contained in this Section 5.14 shall limit any
FHS Successor from owning and operating any business (or line of business), for
the benefit of the enrollees of the FHS Successor or other third parties with
whom the FHS Successor contracts, which would otherwise be construed as
violating the provisions of this Section 5.14; provided that the FHS Successor
shall be bound to this Section 5.14 with respect to the business of the Company
and the Affiliated Business, including business that would have been
attributable to the Company but for the Change of Control of the Company; and
provided further that except as expressly otherwise stated herein, all terms,
conditions and obligations of this Agreement shall become the obligations of
any FHS Successor. The Buyer and the FHS Successor shall use their respective
best efforts to agree on the allocation of enrollees between FHS and the FHS
Successor that are subject to this provision. To the extent that the Company
acquires any managed care company that has an ownership in or otherwise
provides services that would conflict with this provision, this provision shall
not apply to the enrollees of such managed care organization as of the
effective date of such acquisition; provided that the provisions of this
Section 5.14 shall continue to apply to any and all current and additional
Affiliated Business. In addition, prior to consummating any acquisition of a
managed care company that has an ownership interest on or otherwise provide
services that would conflict with this Section 5.14, the Company shall notify
Buyer of such acquisition, and Buyer shall engage in good faith negotiations
regarding cooperative efforts with such entity, including Buyer's opportunity
to acquire such business.

                  (d) Notwithstanding anything contained herein to the
contrary, in the event of a breach or threatened breach of the covenants
contained in Section 5.14(a) hereof, Buyer may, in addition to any other
available remedies, be entitled to an injunction enjoining the Company and its
Affiliates or any person or persons acting for or with the Company in any
capacity whatsoever from violating any of the terms herein, in accordance with
applicable law regarding the award of an equitable remedy.

         5.15 RETENTION OF LITIGATION BY THE COMPANY. The Parties agree that
the Company shall retain all actions, suits and other legal and administrative
proceedings and governmental investigations pending or threatened against FHPS,
or FHPS' properties or assets, or the Purchased Assets. The Parties agree that
the Buyer has not agreed to assume, and shall not be required to assume, any
such pending or threatened action, suit or other legal or administrative
proceeding or governmental investigation, and the Company agrees that it will
take all actions and do all things necessary to ensure that Buyer is not liable
for any of the foregoing.

         5.16 FHPS FUNDS. The Company shall cause FHPS to have not less than
Five Million Dollars ($5,000,000.00) in cash immediately prior to and at the
Closing.

                    REMEDIES FOR BREACHES OF THIS AGREEMENT

         8.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All of the
representations and warranties of the Parties contained in this Agreement shall
survive the Closing (except if the Party suffering Adverse Consequences knew or
had reason to know of any misrepresentation or breach of warranty or covenant
at the time of Closing) and continue in full force and effect thereafter until
the earlier of: (i) the completion of the Buyer's consolidated audit for the
fiscal year ending March 31, 2000, or (ii) ninety (90) days following the end

         8.2 INDEMNIFICATION PROVISIONS FOR BENEFIT OF BUYER. In the event any
Company Party breaches (or in the event any third party alleges facts that, if

warranties, and covenants of the Company Parties contained herein, then the
Company agrees to indemnify Buyer from and against any Adverse Consequences
Buyer may suffer through and after the date of the claim for indemnification
(including any Adverse Consequences suffered after the end of any applicable

<PAGE>   30



Consequences suffered after the end of any applicable survival period)
resulting from, arising out of, relating to, in the nature of or caused by the
breach (or the alleged breach), subject to the limitations set forth below.

         8.4 PROCEDURE FOR MATTERS INVOLVING THIRD PARTIES.

                  (a) If any third party shall notify any Party (the
"INDEMNIFIED PARTY") with respect to any matter (a "THIRD PARTY CLAIM") which
may give rise to a claim for indemnification against any other Party (the
"INDEMNIFYING PARTY") under this Article 8, then the Indemnified Party shall
promptly issue a Claim Notice to the Indemnifying Party with respect thereto.

                  (b) Any Indemnifying Party will have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice
reasonably satisfactory to the Indemnified Party so long as (i) the
Indemnifying Party notifies the Indemnified Party in writing within fifteen
(15) days following the receipt of the Claim Notice that the Indemnifying Party
will indemnify the Indemnified Party from and against the entirety of any
Adverse Consequences the Indemnified Party may suffer resulting from, arising
out of, relating to, in the nature of, or caused by the Third Party Claim, (ii)
upon request of the Indemnified Party, the Indemnifying Party provides the
Indemnified Party with evidence reasonably acceptable to the Indemnified Party
that the Indemnifying Party will have the financial resources to defend against
the Third Party Claim and fulfill its indemnification obligations hereunder,
and (iii) the Indemnifying Party conducts the defense of the Third Party Claim
actively and diligently.

                  (c) The Indemnified Party: (i) may retain separate co-counsel
at its sole cost and expense and participate in the defense of the Third Party
Claim and (ii) will not consent to the entry of any judgment or enter into any
settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party (not to be withheld unreasonably); and the
Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnified Party (not to be withheld unreasonably).

                  (d) In the event any of the conditions in Section 8.4(b) is
or becomes unsatisfied, (i) the Indemnified Party may defend against the Third
Party Claim in any manner it reasonably may deem appropriate, (ii) the
Indemnifying Parties will reimburse the Indemnified Party promptly and
periodically for the costs of defending against the Third Party Claim
(including reasonable attorneys' fees and expenses), and (iii) the Indemnifying
Parties will remain responsible for any Adverse Consequences the Indemnified
Party may suffer resulting from, arising out of, relating to, in the nature of,
or caused by the Third Party Claim to the fullest extent provided in this
Article 8.

         8.5 NOTICE OF CLAIM. A Party suffering Adverse Consequences that gives
or could give rise to a claim for indemnification under this Article 8 shall
promptly notify each other Party thereof in writing (a "CLAIM NOTICE") in
accordance with Section 10.1. The Claim Notice shall contain a brief
description of the nature of the Adverse Consequences suffered and, if
practicable, an aggregate dollar value estimate of the Adverse Consequence
suffered. No delay in 



<PAGE>   31



the issuance of a Claim Notice shall relieve any Party from any obligation
under this Article 8, unless and solely to the extent such Party is thereby
prejudiced.

         8.6 LIMITATION ON AND EXPIRATION OF INDEMNIFICATION. Notwithstanding
anything in this Article 8 to the contrary, the Company's rights to
indemnification from Buyer, and Buyer's rights to indemnification from the
Company, shall be limited as follows:

                  (a) all rights of the parties hereto to indemnification
hereunder for breaches of representations and warranties shall expire following
the completion of the Buyer's consolidated audit for the fiscal year ending
March 31, 2000; provided, however, if, prior to such expiration, a state of
facts shall have become known which threatens to give rise to a liability
against which any party hereto would be entitled to indemnification hereunder
and the indemnified party shall have given notice of such facts to the
indemnifying party, then the rights of the indemnified party to indemnification
with respect to such liability shall continue until such liability shall have
been finally determined and disposed of; and provided, further, that any
obligation for indemnification by the Company arising out of Taxes shall
continue for the period of the applicable statute of limitations for such
Taxes.

                  (b) No party shall be entitled to indemnification pursuant to
Section 8.1 or 8.2 unless and until the aggregate amount of damages resulting
from any and all indemnification sustained by such party exceeds $500,000.
Further, the aggregate amount to which an Indemnified Party shall be entitled
to recover for all obligations of indemnification under this Section 8 shall
not exceed the amount of $20 million.

                  (c) whenever the word "material" or phrase "Material Adverse
Effect" is used in this Agreement, it shall be construed as referring to
damages with respect to any individual claim which exceeds $75,000.

         8.7 ADJUSTMENT FOR INSURANCE. The amount which an Indemnifying Party
is required to pay to, for or on behalf of the Indemnified Party pursuant to
this Article 8 shall be adjusted (including, without limitation, retroactively)
by any insurance proceeds actually recovered by or on behalf of such
Indemnified Party in reduction of the related indemnifiable loss (the
"INDEMNIFIABLE LOSS"). Amounts required to be paid, as so reduced, are
hereinafter sometimes called an "INDEMNITY PAYMENT". If an Indemnified Party
has received or has had paid on its behalf an Indemnity Payment for an
Indemnifiable Loss and subsequently receives insurance proceeds for such
Indemnifiable Loss, then the Indemnified Party shall (x) promptly notify the
Indemnifying Party of the amount and nature of such proceeds, and (y) pay to
the Indemnifying Party the amount of such insurance proceeds or, if lesser, the
amount of the Indemnity Payment.

         8.8 MITIGATION OF LOSS. Each Indemnified Party is obligated to use all
reasonable efforts to mitigate to the fullest extent practicable the amount of
any Indemnifiable Loss for which it is entitled to seek indemnification
hereunder, and the Indemnifying Party shall not be required to make any payment
to an Indemnitee in respect of such Indemnifiable Loss to the extent such
Indemnified Party failed to comply with the foregoing obligation.

         8.9 SUBROGATION. Upon making any Indemnity Payment, the Indemnifying
Party will, to the extent of such payment, be subrogated to all rights of the
Indemnified Party against 



<PAGE>   32



any third party in respect of the Indemnifiable Loss to which the payment
relates; provided, however, that until the Indemnified Party recovers full
payment of its Indemnifiable Loss, any and all claims of the Indemnifying Party
against any such third party on account of such payment are hereby made
expressly subordinated and subjected in right of payment of the Indemnified
Party's rights against such third party. Without limiting the generality of any
other provision hereof, each such Indemnified Party and Indemnifying Party will
duly execute, upon request, all instruments reasonably necessary to evidence
and perfect the above-described subrogation and subordination rights.

         8.10 OTHER INDEMNIFICATION PROVISIONS. The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy (including without limitation any such remedy
arising under Environmental, Health, and Safety Requirements) any Party may
have with respect to the transactions contemplated by this Agreement; provided,
however, that the limitations contained in Section 8.6 shall apply to such
remedies, except with respect to any equitable remedy, or any rights of any of
the parties arising under the Service Agreement.

                                   ARTICLE 9
                       TERMINATION, AMENDMENT AND WAIVER

         9.1 TERMINATION. This Agreement may be terminated at any time prior to
the Closing Date:

                  (a) by mutual written consent of all of the parties hereto at
any time prior to the Closing; or

                  (b) by Buyer upon delivery of written notice to the Company
in accordance with Section 10.1 of this Agreement in the event of a material
breach by a Company Party of any provision of this Agreement; or

                  (c) by the Company upon delivery of written notice to Buyer
in accordance with Section 10.1 of this Agreement in the event of a material
breach by Buyer of any provision of this Agreement; or

                  (d) by Buyer or the Company upon delivery of written notice
to the other in accordance with Section 10.1 of this Agreement, if the Closing
shall not have occurred by March 31, 1999, unless the failure of the Closing to
occur is the result of a breach by the terminating party that caused the
Closing to be delayed.

         9.2 EFFECT OF TERMINATION. Except for the provisions of Article 8 and
Section 10.3 hereof, which shall survive any termination of this Agreement, in
the event of termination of this Agreement pursuant to Section 9.1, this
Agreement shall forthwith become void and of no further force and effect, and
the parties shall be released from any and all obligations hereunder; provided,
however, that nothing herein shall relieve any party from liability for the
willful breach of any of its representations, warranties, covenants or
agreements set forth in this Agreement.

                             ADVANCE PARADIGM, INC.

                                WARRANT AGREEMENT


         This Warrant Agreement (this "Agreement") dated as of February 26, 1999
is entered into by and between Advance Paradigm, Inc., a Delaware corporation
(the "Company") and Foundation Health Systems, Inc.("FHS").


                               TERMS OF AGREEMENT

         NOW THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and FHS hereby agree as follows:

         Section 1. SERVICES AGREEMENT. Reference is made to that certain
Services Agreement dated as of the date hereof entered into by and among the
Company, Integrated Pharmaceutical Services and FHS (the "Services Agreement").
Capitalized terms not otherwise defined herein shall have the meanings given to
them in the Services Agreement.

         Section 2. GRANT OF THE RIGHT TO PURCHASE COMMON STOCK. The Company
hereby grants to FHS the right, and FHS shall be entitled, subject to the terms
and conditions hereinafter set forth, to purchase from the Company 200,000
shares of its common stock, par value $0.01 per share (the "Common Stock")(which
number is referred to herein as the "Total Exercise Number") at a per share
exercise price equal to $35.50 (the "Exercise Price"). The right to purchase
such shares shall be evidenced by five (5) warrant certificates each in the form
of Exhibit A hereto (collectively, the "Warrant Certificates" and each a
"Warrant Certificate"). Subject to Section 3 hereof, each Warrant Certificate
shall be delivered to the FHS following the Vesting Date (as defined below)
thereof. The Total Exercise Number and Exercise Price of such shares are subject
to adjustment as provided in Section 4 hereof.

         Section 3. EXERCISE OF WARRANT CERTIFICATES. The purchase rights
granted hereunder will be exercisable as to twenty percent (20%) of the Total
Exercise Number as of the first anniversary of the effective date of the
Services Agreement, and the right to exercise with respect to an additional
twenty percent (20%) of the Total Exercise Number will accrue on each of the
next four anniversaries of the effective date of the Services Agreement (each a
"Vesting Date") and will be cumulative; provided, however, that if on any
vesting date the number of lives for which the Company is providing integrated
pharmacy benefit management services under the Services Agreement is less than
four (4) million, then the scheduled vesting for such date will be forfeited.
The Warrant Certificates may be exercised only so long as the Company is the
exclusive vendor of integrated pharmacy benefit management services for FHS,
consistent with and subject to the terms and conditions of the Services
Agreement. Except as otherwise provided for herein, the term of the Warrant
Certificates and the right to purchase Common 

<PAGE>   2

Stock as described therein shall commence on the Vesting Date of such Warrant
Certificate and will end on the earlier of February 26, 2005 or three months
following the termination date of the Services Agreement (the "Exercise
Period"). Shares of Common Stock purchased upon exercise of each Warrant
Certificate shall at the time of purchase be paid for in full. To the extent
that the right to purchase shares has accrued hereunder, the Warrant
Certificates may be exercised by written notice to the Company in the form
attached to the Warrant Certificates, which specifies an exercise date (the
"Date of Exercise"), accompanied by full payment for the shares by wire transfer
or certified or official bank check or the equivalent thereof acceptable to
Company. Upon the initial exercise of a Warrant Certificate, FHS and the Company
shall execute and enter into the Stockholders Agreement attached hereto as
Exhibit B (the "Stockholders Agreement").

         At the time of delivery, the Company shall, without stock transfer tax
to the holder of the Warrant Certificate ("Holder"), deliver to the Holder (or
to such other person as the Holder directs) at the principal office of the
Company, or such other place as shall be mutually agreed upon, a certificate or
certificates for such shares, provided, however, that the time of delivery may
be postponed by the Company for such period as may be required for it with
reasonable diligence to comply with any requirements of law. The Company at the
time of exercise will require in addition that the registered owner of the
shares deliver an executed copy of the Stockholder Agreement, an investment
representation in form acceptable to the Company, and the Company will place a
legend on the certificate for such Common Stock restricting the transfer of
same. At no time shall the Company have any obligation or duty to register under
the Securities Act of 1933 (the "1933 Act") the Common Stock issuable upon
exercise of a Warrant Certificate.

         Section 4. ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SHARES. The
Exercise Price and number of shares of Common Stock purchasable pursuant to the
exercise of the Warrant Certificates shall be subject to adjustment from time to
time as follows:

         (a) Adjustment for Combinations or Consolidations of Common Stock. In
the event the Company, at any time or from time to time after the date hereof,
effects a subdivision or capital reorganization of its outstanding Common Stock
for a greater or lesser number of shares, then and in each such event the Total
Exercise Number and the Exercise Price shall be adjusted proportionately such
that FHS is entitled to purchase the same percentage of all shares of the
Company's outstanding capital stock then issued and issuable for the same
aggregate consideration as such Holder was entitled to purchase immediately
prior to such event.

         (b) Adjustment for Certain Dividends and Distributions. In the event
the Company at any time or from time to time after the date hereof shall pay a
dividend payable in Common Stock of the Company, or otherwise make a
distribution of Common Stock to its stockholders, then the Exercise Price shall
be adjusted, from and after the record date of such dividend or the date of such
distribution, to that price determined by multiplying the Exercise Price by a
fraction,

                  (i) the numerator of which shall be the total number of shares
                  of capital stock issued and outstanding or deemed to be issued
                  and outstanding immediately prior to the time of such issuance
                  or the close of business on such record date; and



                                       2
<PAGE>   3

                  (ii) the denominator of which shall be the number of shares of
                  capital stock issued and outstanding or deemed to be issued
                  and outstanding immediately prior to the time of such issuance
                  or the close of business on such record date plus the number
                  of shares of capital stock to be issued;

         provided, however, that if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Exercise Price shall be recomputed accordingly as of
the close of business on such record date and thereafter the Exercise Price
shall be adjusted pursuant to this Section 4(b) as of the time of actual payment
of such dividend or distribution. FHS shall thereafter be entitled to purchase,
at the Exercise Price resulting from such adjustment, the number of shares of
Common Stock (calculated to the nearest whole share) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of Common Stock issuable upon the exercise hereof immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

         (c) Number of Shares. Upon any adjustment of the Exercise Price
pursuant to Section 4(b) hereof, FHS shall thereafter (until another such
adjustment) be entitled to purchase, at the new Exercise Price, the number of
shares, calculated to the nearest full share, obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the new Exercise Price resulting from such
adjustment.

         Section 5. RESERVATION AND AUTHORIZATION OF COMMON STOCK. The Company
shall at all times reserve and keep available, free from preemptive rights, out
of its authorized but unissued Common Stock, solely for the purposes of
effecting the exercise of all outstanding Warrant Certificates, the full number
of shares of Common Stock issuable upon the exercise of all outstanding Warrant
Certificates. For the purpose of this Section 5, the full number of shares of
Common Stock issuable upon the exercise of all outstanding Warrant Certificates
shall be computed as if at the time of computation of such number of shares of
Common Stock all outstanding Warrant Certificates were held by a single holder.
The Company shall from time to time, in accordance with applicable law, increase
the authorized amount of its Common Stock if at any time the authorized amount
of its Common Stock remaining unissued shall not be sufficient to permit the
exercise of all Warrant Certificates at the time outstanding.

         Section 6.        TRANSFERABILITY.

         (a) The Warrant Certificates are not transferable by FHS except to the
Company, affiliates of FHS or an FHS Successor (as defined in the Services
Agreement). Any permitted transfer of a Warrant Certificate shall be recorded on
the books of the Company upon receipt by the Company of a notice of transfer in
the form attached hereto as Exhibit B, at its principal offices and the payment
to the Company of all transfer taxes and other governmental charges imposed on
such transfer. The shares of Common Stock purchased by FHS are not transferable
except as provided in the Stockholders Agreement.



                                       3
<PAGE>   4

         (b) Unless and until otherwise permitted by this Section and the
Stockholders Agreement, each certificate representing Common Stock initially
issued upon the exercise of each Warrant Certificate (a "Stock Certificate"),
and each certificate for Common Stock issued to any subsequent transferee of any
such certificate, shall be stamped or otherwise imprinted with a legend in
substantially the following form:

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY BE
                  REOFFERED AND SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION
                  FROM SUCH REGISTRATION IS AVAILABLE. THE SECURITIES
                  REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
                  RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND
                  CERTAIN OTHER AGREEMENTS SET FORTH IN A STOCKHOLDERS AGREEMENT
                  BETWEEN THE COMPANY AND FOUNDATION HEALTH SYSTEMS, INC., DATED
                  AS OF ______________, A COPY OF WHICH MAY BE OBTAINED BY THE
                  HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF BUSINESS
                  WITHOUT CHARGE."

                  Prior to any permitted transfer of a Warrant Certificate or
any Stock Certificate, the holder thereof shall furnish, at the expense of such
holder, to the Company an opinion of counsel, reasonably satisfactory in form
and substance to the Company, to the effect that such transfer is exempt from
registration under the Securities Act. Upon any exercise of any Warrant
Certificate for shares of Common Stock to be registered in the name of a person
other than FHS, FHS shall furnish, at the expense of FHS, to the Company an
opinion of the General Counsel of FHS, reasonably satisfactory in form and
substance to the Company, to the effect that the issuance of the shares of
Common Stock to such other person upon exercise of the Warrant is exempt from
registration under the Securities Act.

         Section 7. FRACTIONAL SHARES. The Company shall not be required to
issue a fractional share of stock upon any exercise of a Warrant Certificate. As
to any final fraction of a share that FHS would otherwise be entitled to
purchase upon exercise of a Warrant Certificate, the Company shall, if it does
not issue a fractional share, pay a cash adjustment in respect of such final
fraction in an amount equal to the same fraction of the Exercise Price per share
of Common Stock.

         Section 8. EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES. In the
event of loss, theft or destruction of a Warrant Certificate, the Company will
make and deliver a new Warrant Certificate of like tenor, in lieu of such
Warrant Certificate, upon receipt by the Company of evidence reasonably
satisfactory to it of such loss, theft, or destruction and indemnity or security
reasonably satisfactory to it, and reimbursement to the Company of all
reasonable expense incidental thereto. In the case of mutilation of a Warrant
Certificate and upon surrender and cancellation of such Warrant Certificate, the
Company will make and deliver a new Warrant Certificate of like tenor, in lieu
of such Warrant Certificate.



                                       4

         Section 9. RIGHTS PRIOR TO EXERCISE OF WARRANT CERTIFICATES. Prior to
the exercise of a Warrant Certificate, FHS shall not be entitled to any rights
of a stockholder of the Company with respect to the Common Stock for which such
Warrant Certificate may then be exercisable, including without limitation the
right to vote, to receive dividends or other distributions or to exercise any
preemptive rights and shall not be entitled to receive any notice of any
proceedings of the Company except as provided herein.

         Section 10. AUTHORIZATION AND ISSUANCE. The Company represents and
warrants to FHS that it has the corporate power and authority to issue the
Warrant Certificates; this Warrant Agreement has been duly authorized, executed
and delivered and the Warrant Certificates, when delivered, will be duly and
validly issued, fully paid and nonassessable; the issuance of the Warrant
Certificates, and the shares of Common Stock issuable upon their exercise, are
not prohibited or restricted by the Certificate of Incorporation or Bylaws of
the Company or any material agreement to which the Company is a party; except
for those agreements for which the Company has received the requisite consents
or waivers; and the shares of Common Stock issuable upon exercise of the Warrant
Certificates, when issued upon exercise of the Warrant Certificates pursuant to
the terms hereof, will be duly and validly issued, fully paid and nonassessable.

         Section 11. REPRESENTATIONS AND COVENANTS OF FHS. This Warrant
Agreement has been entered into by the Company in reliance upon the following
representations and covenants of FHS:

         (a) Investment Purpose. The right to acquire the Common Stock issuable

no present intention of selling or engaging in any public distribution of the
same except pursuant to a registration or exemption.

         (b) Private Issue. FHS understands (i) that the Common Stock issuable
upon exercise of the Warrant Certificates is not registered under the 1933 Act
or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 11.

         (c) Financial Risk. FHS has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of its
investment, and has the ability to bear the economic risks of its investment.

         (d) Risk of No Registration. FHS understands that if the Company does
not register with the Securities and Exchange Commission pursuant to Section 11
of the 1933 Act, or file reports pursuant to Section 15(d) of the Securities
Exchange Act of 1934 (the "1934 Act"), or if a registration statement covering
the securities under the 1933 Act is not in effect when it desires to sell the
Common Stock issuable upon exercise of the right to purchase, it may be required
to hold such securities for an indefinite period. FHS also understands that any
sale of its rights to purchase Common Stock which might be made by it in
reliance upon Rule 144 under the 1933 Act may be made only in accordance with
the terms and conditions of that Rule.

                           plan transition. The cost of any programming required
                           shall be the financial responsibility of Advance
                           Paradigm.

                  (iii)    For the TRICARE business, Advance Paradigm shall be
                           financially responsible for any reasonable costs of
                           programming required to the systems of the regional
                           claims subcontractors (Blue Cross and Blue Shield of
                           South Carolina and Wisconsin Physician Services) to
                           accommodate this transition. By the Effective Date of
                           the transition of the TRICARE 


                                                                          Page 5
<PAGE>   6

                           business, Advance Paradigm will have completed the
                           necessary system programming to accommodate the
                           unique paid claims transmission formats for each of
                           the regional claims subcontractors and the remote
                           eligibility query.

                  (iv)     During the Transition Period, IPS shall manage and
                           support the Procare system in a manner consistent
                           with past practices of FHS, regulatory requirements
                           and other specific client based requirements
                           applicable to the claims processed on the Procare
                           system. On or before the Closing, the parties shall
                           agree upon and enter into a management agreement
                           pursuant to which these services will be rendered
                           during the Transition Period.

         (b)      Eligibility Tape and Updates. At least ten (10) calendar days
                  prior to the Effective Date of each Plan, FHS shall cause each
                  of the FHS Affiliated Plans to provide Advance Paradigm with a
                  complete and final eligibility file which shall identify all
                  Eligible Members and set forth all pertinent eligibility data
                  specified by Advance Paradigm ("Eligibility Tape"). Such
                  eligibility data for each FHS Affiliated Plan shall be in the
                  format currently used by such FHS Affiliated Plan. FHS shall
                  cause each of the FHS Affiliated Plans to provide updates to
                  the Eligibility Tape to Advance Paradigm in a format
                  consistent with such FHS Affiliated Plan's requirements as
                  frequently as mutually agreed to by the parties hereto.
                  Subject to receipt of confirmation from each FHS Affiliated
                  Plan as to the accuracy of each update to the Eligibility
                  Tape, prior to the end of the business day following Advance
                  Paradigm's receipt of such update, Advance Paradigm shall
                  accept claims for covered Prescriptions that are dispensed to
                  Eligible Members after the effective date of their eligibility
                  and shall deny claims for covered Prescriptions that are
                  dispensed to terminated members after the effective date of
                  their termination. Advance Paradigm and the Participating
                  Pharmacies shall be entitled to rely on the accuracy and
                  completeness of the Eligibility Tape and updates thereto
                  provided by each FHS Affiliated Plan. Advance Paradigm will
                  accommodate the remote eligibility requirements of the TRICARE
                  business through an on-line, real-time query through the
                  regional claims subcontractors. The Advance Paradigm system
                  will be programmed to accept and interpret the eligibility
                  response and other real-time, on-line information that is
                  returned from the regional claims subcontractors to determine
                  appropriate copays, coordination of benefits and beneficiary
                  jurisdiction.

         (c)      Distribution of Materials. FHS shall cause each FHS Affiliated
                  Plan to provide the Eligible Members with copies of claims
                  forms and informational material regarding the utilization of
                  the pharmacy network and the mail service pharmacy. FHS shall
                  cause each FHS Affiliated Plan to provide each Eligible Member
                  with an identification card, for purposes of (among other
                  things) accessing the Participating Pharmacies.



                                                                          Page 6

3.       Formulary/Rebate Management Services. Advance Paradigm shall provide
         formulary and rebate management services in accordance with this
         Section 3. Nothing herein shall be construed as a limitation on Advance
         Paradigm's right to provide comprehensive PBM Services to its other
         clients including, without limitation, formulary management and drug
         manufacturer contracting services.

         (a)      Rebate Contracting. In order to maximize savings on drug
                  spending for both the FHS Affiliated Plans and Advance
                  Paradigm's other pharmacy benefit management business, the
                  parties, acting on behalf of all entities for which they
                  provide formulary/rebate services, intend to negotiate
                  together for new Drug Manufacturer Agreements that cover all
                  of such business. The parties acknowledge that each is a party
                  to agreements with certain drug manufacturers for discounts
                  relating to drug utilization. Pursuant to the procedures
                  mutually agreed to by the parties, Advance Paradigm and Client
                  shall jointly negotiate with targeted manufacturers, in
                  accordance with the Work Plan set forth in Exhibit C in order
                  to improve the terms of their respective drug manufacturer
                  arrangements and enter into new contracts upon such terms as
                  mutually agreed (the "Drug Manufacturer Agreements"). The
                  parties shall work together to establish and thereafter
                  modify, as appropriate a work plan to be agreed upon prior to
                  the Closing and to be attached hereto as Exhibit C, regarding
                  negotiations with drug manufacturers to ensure that the
                  parties' overall intent of maximizing the relationship created
                  by this Service Agreement is met (the "REBATE STRATEGY WORK
                  PLAN"). Such work plan shall identify the responsibility of
                  the parties with respect to all such negotiations, the parties
                  to the agreement, the administration of such agreements, FHS
                  Affiliated Members' formulary requirements, the selection of
                  appropriate drug manufacturers to support formulary
                  requirements, the scope of drug manufacturer payments, and
                  other matters related thereto. The parties shall use their
                  reasonable best efforts to comply with the Rebate Strategy
                  Work Plan and schedule, in order to timely implement the joint
                  negotiation strategy contemplated hereby.

         (b)      IPS Manufacturer Agreement. FHS and IPS agree that until such
                  time as new Drug Manufacturer Agreements are jointly entered
                  into for all drugs covered by the Formulary, upon the request
                  of Advance Paradigm, FHS shall use its best efforts to cause
                  the Non-affiliated Business to be eligible for rebates under
                  the existing IPS rebate agreements. FHS agrees to service such
                  rebates in accordance with Advance Paradigm's instructions.
                  IPS agrees that all Rebates collected by IPS based on the
                  utilization of the Non-affiliated Business prior to Closing
                  shall be paid by IPS following Closing pursuant to the terms
                  and conditions of the respective agreements for the
                  Non-affiliated Business, and that Advance Paradigm's
                  obligation to pay such rebates on such business shall begin
                  with the rebates collected for the Quarter ending June 30,
                  1999.

         (c)      Formulary Development and Strategy. Pursuant to the terms of
                  the Drug Manufacturer Agreements, Advance Paradigm shall
                  maintain the formulary contemplated by the Work Plan referred
                  to in Section 3(a), for each FHS Affiliated Plan subject to
                  approval by such FHS Affiliated Plan, for the benefit of the
                  FHS Affiliated Plans (the "Formulary"), and recommend
                  clinically 


                                                                          Page 7
<PAGE>   8

                  appropriate, cost effective strategies designed to promote
                  Formulary compliance. Advance Paradigm shall be entitled, from
                  time to time, to review the Formularies and make
                  recommendations to the JNC, referred to in Exhibit C, as
                  Advance Paradigm deems appropriate, subject to approval by FHS
                  and the appropriate FHS Affiliated Plan. Advance Paradigm
                  recognizes and agrees that FHS has a national pharmacy and
                  therapeutics committee, and that the establishment of, and
                  changes to the formulary, steerage, intervention and other
                  clinical decision-making will be based on this committee's
                  independent approval. Advance Paradigm agrees to cooperate
                  with Client in the implementation of Formulary steerage
                  controls at the point-of-sale, including without limitation,
                  hard edit NDC blocks, differential patient copays, soft edits
                  (e.g. on-line formulary messages) and pharmacist intervention
                  for Formulary compliance and therapeutic interchange programs,
                  all as approved by Client.

         (d)      Formulary Distribution. Advance Paradigm will provide
                  camera-ready art work, design and copy for the Formulary to
                  Client which will then publish the number of copies of such
                  Formulary as required for each FHS Affiliated Plan. Promptly
                  following the receipt of the camera-ready copy, Client hereby
                  agrees to distribute the copies of the Formulary to all
                  physicians included in the FHS Affiliated Plan's respective
                  preferred physician networks. Client shall be responsible for
                  the payment of all printing, publication and distribution
                  expenses associated with the Formulary, including all
                  printings and reprints of the Formulary as may be required by
                  Client and bulk mailing materials for physician education,
                  such as newsletters and drug monographs.

         (e)      Submission of Claims Data. Within fifteen (15) days following
                  the last day of each Quarter, for Non-affiliate Business which
                  has not been transitioned to Advance Paradigm and for which
                  FHS (or its affiliate) serves as the claims processor, Client
                  shall use its best efforts to provide Advance Paradigm, in a
                  format mutually agreeable to the parties, with documentation
                  of the drug utilization for the immediately preceding Quarter.
                  Client acknowledges that prescription claims submitted to
                  Advance Paradigm more than fifteen (15) days following the
                  last day of the Quarter during which claims arose shall not be
                  automatically eligible for Rebates in such quarter. If
                  possible, without delaying the payment of rebates to other
                  Health Plans, such claim shall be submitted for Rebates in the
                  following quarter. Client acknowledges that Advance Paradigm's
                  timely receipt of accurate claims data is essential for rebate
                  billing for all of Advance Paradigm's business, and that
                  Advance Paradigm has financial guarantees and penalties
                  associated with the timely submission of claims utilization
                  data.

         (f)      Rebate Payment. All Rebates on the FHS Affiliated Plans
                  Members' drug utilization shall be paid directly to IPS.



                                                                          Page 8
<PAGE>   9

         (g)      Warranty by Client. Client represents and warrants to Advance
                  Paradigm that any Prescription claims which it submits to
                  Advance Paradigm for Rebate adjudication shall be
                  Prescriptions that were dispensed to Eligible Members for
                  their "own use" under a Pharmacy Benefit for which the FHS
                  Affiliated Plan bears the risk of payment. Client further
                  represents and warrants that it shall promptly distribute
                  copies of the Formulary in accordance with Section 3(d)
                  hereof. In the event the foregoing warranty is not true with
                  respect to any Eligible Member, the Rebates received as a
                  result of such Member's drug utilization will be deemed to be
                  "improper rebates" under Section 3(h) hereof.
                  
         (h)      Eligible Data. Drug utilization which has been submitted by
                  any entity other than Advance Paradigm to drug manufacturers
                  for discounts, Rebates or other price reduction, specifically
                  including Medicaid, Medicare or other state or federal health
                  care program which receives Rebates directly from drug
                  manufacturers, shall not be eligible for Rebates from Advance
                  Paradigm. Client shall clearly identify to Advance Paradigm
                  those Eligible Members whose drug utilization has been
                  otherwise submitted to drug manufacturers or whose claims have
                  been or will be filed for reimbursement with Medicaid,
                  Medicare or any other state or federal health care program. If
                  Client fails to identify such members or claims and any drug
                  manufacturer's audit of its Rebate program reveals improperly
                  calculated Rebates involving such members and claims, then
                  Client shall be solely responsible for the reimbursement of
                  any Rebates to the respective drug manufacturers and will
                  indemnify Advance Paradigm against any damages suffered as a
                  result of Client's failure to make such reimbursement.
                  Notwithstanding the foregoing, this provision shall not be
                  construed to prohibit Client from participating in Medicare
                  risk contracting.

4.                Advance Paradigm Retail Pharmacy Network Services and Claims
                  Adjudication. Advance Paradigm shall adjudicate claims for
                  Prescriptions furnished by pharmacies under the Plan in
                  accordance with the following terms and conditions:

         (a)      Network Contract Negotiations. During the Transition Period
                  and thereafter, Advance Paradigm will renegotiate network
                  pharmacy contract rates for those pharmacies located in the
                  respective service areas of a Health Plan, for such Health
                  Plan (the "Primary Network"). Such contracts shall meet
                  applicable statutory and regulatory requirements and mutually
                  agreed access and service levels. As of the Closing Date,
                  however, IPS will assign all of its rights and obligations
                  under, and Advance Paradigm will assume responsibility for
                  performance of, the IPS' network pharmacy contracts; and, to
                  the extent such assignment does not include a novation of
                  Advance Paradigm for IPS, Advance Paradigm shall indemnify and
                  hold IPS and FHS harmless for any liability arising under such
                  agreements, in accordance with Section 13, below. In the event
                  that Advance Paradigm has failed or is otherwise unable to pay
                  any such pharmacies in accordance with such agreements (a
                  "DEFAULT IN PHARMACY PAYMENT"). Upon written notice to Advance
                  Paradigm and unless Advance Paradigm notifies FHS within five
                  (5) business days that such amounts have not been paid to the
                  pharmacies or to the pharmacies' affiliates or designees, FHS,
                  or an FHS Affiliated Plan may make payment in order to remedy
                  any such Default in 


                                                                          Page 9
<PAGE>   10

                  Pharmacy Payment and FHS shall have the right to offset any
                  amounts that would have been due to Advance Paradigm for such
                  claims under this Service Agreement. Except as provided
                  herein, Client agrees that during the term of this Agreement,
                  unless this Section 4 is earlier terminated pursuant to
                  Section 11(c)(ii) hereof, Client shall not, and shall cause
                  the FHS Affiliated Plans not to negotiate, contract or
                  otherwise agree with any retail pharmacy for purposes of
                  establishing a pharmacy network, except to the extent required
                  by applicable law or regulation. Client shall reimburse
                  Advance Paradigm for network pharmacy claims at the rates set
                  forth in Exhibit D. Notwithstanding the foregoing, under no
                  circumstances will the Pharmacy Network rates exceed the rates
                  in Exhibit D, except as a result of any material change in the
                  pricing structure in the industry.

                  Notwithstanding the foregoing, Advance Paradigm understands
                  and agrees that pursuant to California law, Health Net, an FHS
                  Affiliated Plan, must have direct agreements with its Primary
                  Network. Health Net agrees that it shall amend all of Health
                  Net's pharmacy agreements with the Primary Network in
                  California to include Advance Paradigm as a party to such
                  agreements. Health Net and Advance Paradigm shall cooperate in
                  order to obtain regulatory approval of such amendment. Advance
                  Paradigm further understands and agrees that if these
                  amendments do not comply with California regulatory
                  requirements, this Section 4(a) shall not apply to Health Net.

                  Advance Paradigm further understands and agrees that in the
                  event any applicable state law requires that an FHS Affiliated
                  Plan have direct agreements with its Pharmacy Network, Advance
                  Paradigm will amend all Pharmacy Network agreements to include
                  such FHS Affiliated Plan as a party. Advance Paradigm shall,
                  and FHS shall cause any such FHS Affiliated Plans to,
                  cooperate in order to obtain regulatory approval of such
                  amendments. If these amendments do not comply with applicable
                  state law, this Section 4(a) shall not apply to such FHS
                  Affiliated Plan.

         (b)      Advance Paradigm National Network. In addition to the Primary
                  Network, the Eligible Members shall have the option, but not
                  the obligation, to access to the nationwide Advance Paradigm
                  Network to obtain Prescriptions outside of the service areas.
                  Advance Paradigm shall process claims submitted by the Advance
                  Paradigm Network in accordance with Advance Paradigm's
                  agreements with such pharmacies, and Client shall reimburse
                  Advance Paradigm for such claims at the rates set forth in
                  Exhibit D. Notwithstanding the foregoing, under no
                  circumstances will the Pharmacy Network rate exceed the rates
                  in Exhibit D, except as a result of any material change in the
                  pricing structure in the industry.

         (c)      Release of Information. Advance Paradigm shall furnish to each
                  Network Pharmacy such information regarding the Eligible
                  Members as is necessary for the operation of the Advance
                  Rx(TM) claims adjudication system. Client hereby authorizes
                  Advance Paradigm to release any necessary information to the
                  Network Pharmacies regarding the applicable Plan and Eligible
                  Members.

                  process Advance Paradigm claim forms submitted by Eligible

                  Plan and the Eligibility Tape; (D) calculate the payment of
                  such claims pursuant to the applicable Plan (each such claim
                  an "Approved Claim"), and (E) calculate the payment of such
                  claims pursuant to the IPS MAC. Advance Paradigm shall

                  Paradigm shall provide IPS and FHS with on-line and real-time

                  therapy; (B) early refills and frequency limitations; (C)
                  duplicate drug; (D) potential drug interaction(s), in which
                  case the provider is notified on-line and the level of
                  severity would be indicated; and (E) minimum/maximum dose
                  range (which includes on-line alert of pharmacist). All such

                  appropriate FHS Affiliated Plan and IPS within ten (10)
                  business days of the end of each month. Any reports requested
                  by Client other than Advance Paradigm's standard reports shall
                  be considered "Special Reports". Should Client request
                  additional reports or Special Reports, Client shall pay

                  system for information and data relating to the FHS Affiliated

                  replication of claims and other transaction data upon request

                  (2) business days upon written notification from IPS of which
                  records failed and the specific reasons for the failure. For
                  purposes of the Performance Guarantees attached hereto as
                  Exhibit G, data files that are materially inaccurate or
                  materially incomplete, as determined by reference to Exhibit
                  E, will be deemed to have not been received during the period
                  beginning on the business day of IPS' written notification to
                  Advance Paradigm of such inaccuracy or incompletion and ending

                  the request). Advance Paradigm shall also provide the
                  programming support necessary to timely implement changes
                  needed to accurately process claims and other transactions on
                  the current claims adjudication system, and Client agrees to

                  which describes the report requested. IPS shall pay Advance
                  Paradigm for such reports in accordance with Section 7(d) set
                  forth below.



                                                                         Page 13

                  Affiliated Plan to agree to surrender to Advance Paradigm the
                  software upon termination of this Agreement. Advance Paradigm
                  agrees not to charge Client or the FHS Affiliated Plans for
                  the Advance Insight(TM)software, provided that Client or the
                  FHS Affiliated Plans shall be responsible for the costs of the
                  hardware and software necessary to run Advance Insight(TM).

         (m)      Year 2000 Readiness. Each party, including FHS on behalf of
                  each FHS Affiliated Plan, represents and warrants that on or

                  party is Year 2000 Compliant on or before July 1, 1999
                  provided, however, that with respect to FHS, IPS and the FHS
                  Affiliated Plans, such representation and warranty shall be
                  limited to Y2K Compliant with regard to data and information
                  supplied to Advance Paradigm and not to their respective
                  businesses, generally.

5.       Mail Service. Subject to this Section 5, during the term of this
         Agreement, Advance Paradigm or its designee shall exclusively provide
         mail service pharmacy for Client:

         (a)      Performance of Services. Pursuant to the arrangement between
                  FHPS and Walgreens (the "Walgreens Arrangement") or such other
                  arrangement as may be approved by FHS from time to time,
                  Advance Paradigm shall provide mail service pharmacy to
                  Client. Advance Paradigm shall use commercially reasonable
                  efforts 


                                                                         Page 14
<PAGE>   15

                  to continue to use Walgreens as the vendor of mail service
                  pharmacy for the FHS Affiliated Plans under substantially
                  similar terms to the Walgreens Arrangement. In the event
                  Walgreens ceases to use Advance Paradigm as its exclusive
                  vendor for formulary/rebate services, then (i) subject to FHS'
                  approval which will not be unreasonably withheld so long as
                  Advance Paradigm has demonstrated that it will provide
                  substantially similar types of services at substantially the
                  same, but no greater cost, Advance Paradigm may perform the
                  mail services for the FHS Affiliated Plans or (ii) Advance
                  Paradigm may place the business with a third party vendor
                  acceptable to FHS, which acceptance will not be unreasonably
                  withheld. In the event either Advance Paradigm or a third
                  party vendor replaces Walgreens, Client and Advance Paradigm
                  shall use best efforts to facilitate the transition from
                  Walgreens to Advance Paradigm or such third party.

         (b)      Right of First Refusal. FHS shall, during the term of this
                  Agreement, have the right to solicit from and/or consider
                  proposals received from third parties to provide substantially
                  similar mail order pharmacy services as are provided under
                  this Agreement. Such right to solicit and/or consider shall be
                  limited to three (3) times during the term of this Agreement,
                  and no more frequently than once in any twelve (12) calendar
                  month period. Upon receipt of any such bona fide third party
                  offer (the "OFFER"), FHS shall promptly notify Advance
                  Paradigm of the terms and conditions of such Offer. Within ten
                  (10) days of Advance Paradigm's receipt of the Offer, the
                  parties shall meet to review the Offer. Following such
                  meeting, Advance Paradigm shall have the right, but not the
                  obligation to: (I) match the Offer directly; (II) enter into
                  the proposed agreement with the third party in accordance with
                  the Offer, for the purposes of providing such mail order
                  pharmacy services in accordance with this Agreement; or (III)
                  enter into an agreement with another party, reasonably
                  acceptable to FHS, on the same terms and conditions as
                  contained in the Offer. In the event that Advance Paradigm
                  does not elect to exercise any of the options described
                  herein, FHS shall be free to accept the Offer, and the
                  obligations regarding mail order pharmacy services hereunder
                  (including any limitations under Section 12) shall terminate.
                  Except as expressly permitted by this Section 5, Client shall
                  not, and FHS shall cause the FHS Affiliated Plans not to,
                  enter into a contract for mail service pharmacy.

6.       Performance Guarantees. Advance Paradigm agrees that the PBM Services
         performed pursuant to this Agreement shall be in accordance with the
         Performance Guarantees set forth in Exhibit G attached hereto.

7.       Fees and Rates.

         (a)    Fees for Services. Beginning on the Closing, unless otherwise
                specified in Exhibit D, FHS agrees to pay Advance Paradigm fees
                in the amounts set forth in Exhibit D attached hereto. In order
                to permit Advance Paradigm to calculate fees owed, within five
                (5) business days of each billing cycle, FHS shall deliver to
                Advance Paradigm a claims detail tape that reflects all pharmacy
                claims processed on IPS' "Procare" system as well as pharmacy
                claims processed for the FHS Affiliated Plans by third party
                vendors.



                                                                         Page 15
<PAGE>   16

         (b)    Rates for Prescription Claims. During the term of this
                Agreement, FHS agrees to pay for Prescriptions dispensed to
                Eligible Members by the mail service pharmacy or the
                Participating Pharmacies, as the case may be, at the rates set
                forth in Exhibit D attached hereto.

         (c)    Savings Goals. The parties will cooperate in negotiations and
                contracting with retail pharmacies and drug manufacturers in
                order to maximize savings in Client's pharmacy spend. Rebate
                savings and retail network savings shall be measured pursuant to
                a methodology mutually agreed to by the parties prior to
                Closing.


                  (i)      Retail Network Savings. Retail Network Savings will
                           be measured on a Quarter by Quarter basis by
                           comparing (A) the network discount rate, plus
                           dispensing fee, received for the Prescriptions for
                           the current quarter, to (B) the Baseline network
                           discount rate plus dispensing fee for retail
                           Prescriptions for the Baseline Period. In the event
                           the retail network savings exceeds $0.12 per paid
                           claim in any Quarter, Advance Paradigm shall be
                           entitled to 20% of such excess. The Baseline Period
                           for retail network savings shall be the calendar
                           quarter ending June 30, 1999.

                  (ii)     Rebate Savings. Savings from Rebate contracting will
                           be measured on a Quarter by Quarter basis by
                           comparing (A) the aggregate rebates earned divided by
                           the total number of paid pharmacy claims for each
                           quarter to (B) the aggregate rebates earned divided
                           by the total number of paid pharmacy claims for the
                           Baseline Period, subject to any modification thereof
                           as agreed to by the parties prior to Closing. In the
                           event the rebate savings exceeds $0.15 per paid claim
                           in any Quarter, then Advance Paradigm shall be
                           entitled to 20% of such excess. Advance Paradigm
                           shall not be entitled to any portion of Rebate
                           savings unless a lower net pharmaceutical cost is
                           achieved by Client, subject to a mutually agreed upon
                           adjustment for changes in utilization and new
                           therapeutic entities, covered by FHS and/or the FHS
                           Affiliated Plans.

         (d)      Special Services or Materials. Upon Client's request, Advance
                  Paradigm will provide Client with identification cards or
                  non-standard services, forms, materials or documents, at a
                  rate mutually agreed upon in writing. In the event Client
                  requests a service, including Special Reports, that require
                  computer programming, Advance Paradigm shall provide Client an
                  estimate of the costs for such computer programming. Advance
                  Paradigm shall not proceed with such programming until Client
                  has agreed to the estimated costs. Client shall pay for all
                  reasonable associated costs including but not limited to
                  Advance Paradigm's internal programming time at a rate of $125
                  per hour or, if Advance Paradigm must engage an outside vendor
                  for programming, at the rate actually incurred by 


                                                                         Page 16
<PAGE>   17

                  Advance Paradigm for such service. Except as otherwise
                  specifically provided herein, Client shall be responsible for
                  the reasonable costs and expenses incurred in the production
                  of forms, materials and documents and the distribution thereof
                  to Client or Eligible Members and for special handling of
                  certain mail service prescriptions.

         (e)      Best Price. Advance Paradigm agrees that, to the extent it
                  participates in any bidding process with the same purchaser of
                  services with which FHS and/or the FHS Affiliated Plans are
                  bidding, at a compensation rate that is more favorable to such
                  third party than the rates charged hereunder, Advance Paradigm
                  shall offer such compensation arrangement to FHS. FHS shall
                  notify Advance Paradigm of any bids submitted under which, if
                  awarded, Advance Paradigm would be providing services.

8.       Payment.

         (a)      Statement of Account. Advance Paradigm shall submit to Client
                  on a semi-monthly basis a statement of account (the "Statement
                  of Account") that reflects the amount due for the
                  Prescriptions dispensed and the fees due for the applicable
                  period.

         (b)      Payment of Statement of Account. Client agrees to pay the
                  amount due reflected on the Statement of Account within two
                  (2) business days of receipt of the Statement of Account by
                  wire or electronic funds transfer to an account designated by
                  Advance Paradigm.

         (c)      Cessation of Services. Should Client, for any reason, fail to
                  pay timely any Statement of Account in accordance with Section
                  8(b) hereof, or become insolvent or generally unable to pay
                  its creditors when due, Advance Paradigm shall be entitled to
                  cease adjudication of claims and/or the dispensing of
                  Prescriptions under this Agreement while maintaining all of
                  Advance Paradigm's rights hereunder.

         (d)      Additional Services. Advance Paradigm shall invoice Client for
                  any additional services performed under this Agreement. Client
                  shall pay such invoice within thirty (30) days of receipt.

         (e)      Interest on Late Payments. Unless Client has disputed an
                  invoice, Client shall pay a finance charge on any unpaid
                  balance which becomes past due until paid in full. Amounts due
                  for Prescriptions dispensed are past due if not paid by the
                  fifteenth (15th) day following receipt of a Statement of
                  Account. Amounts due for fees and other charges hereunder are
                  past due if not paid by the thirtieth (30th) day following
                  receipt of an invoice or Statement of Account. The finance
                  charge for past due amounts shall be in an amount equal to one
                  and one-half percent (1.5%) per month, unless such rate
                  exceeds the maximum rate allowable by applicable law, in which
                  case such amounts shall bear interest at the maximum legally
                  allowable rate.



                                                                         Page 17
<PAGE>   18

         (f)      Payments By Advance Paradigm. Any payments due to Client from
                  Advance Paradigm under Exhibit G or otherwise shall be payable
                  to Client within fifteen days of the date of notice from the
                  Client that such amounts are due. Unless Advance Paradigm has
                  a disputed invoice, amounts due for such charges hereunder are
                  past due if not paid by the thirtieth (30th) day following
                  receipt of the notice from Client, subject to any resolution
                  of a dispute relating thereto. The finance charge for past due
                  amounts shall be in an amount equal to one and one-half
                  percent (1.5%) per month, unless such rate exceeds the maximum
                  rate allowable by applicable law, in which case such amounts
                  shall bear interest at the maximum legally allowable rate.

         (g)      Right of Offset. In the event of any uncured payment default,
                  either party shall be entitled, and the parties hereby
                  authorize each other, to offset the amount of such payment
                  defaults against any amounts otherwise payable to such party;
                  provided, however, that in the event of any dispute over the
                  underlying claim giving rise to such setoff, such dispute
                  shall have been resolved in accordance with the dispute
                  resolution procedure set forth in this Agreement.

9.       Records.

         (a)      Advance Paradigm shall maintain, in original form, on
                  microfilm or computer tape, documentation of all claims
                  processed in accordance with applicable law and for a minimum
                  period of seven (7) years. Subject to Section 14 hereof, all
                  such records, while maintained by Advance Paradigm, shall be
                  accessible to Client, and to any governmental or regulatory
                  agency with jurisdiction over Client, for examination and
                  audit during the term of this Agreement. In addition, Advance
                  Paradigm shall maintain, in original form, on microfilm or
                  computer tape, a copy of this Agreement in accordance with
                  applicable law.

         (b)      During and after the term of this Agreement, Advance Paradigm
                  shall be entitled to use on a non-exclusive basis the drug and
                  related data collected by Advance Paradigm for research, cost
                  analyses, cost comparison or other business purposes of
                  Advance Paradigm, all without charge to Advance Paradigm.
                  Advance Paradigm shall comply with all applicable federal and
                  state laws, including but not limited to, confidentiality laws
                  regarding medical records, in the use of such data.

10.      Term and Renewal. Unless otherwise terminated in accordance with
         Section 11 herein, or otherwise extended, this Agreement shall commence
         on April 1, 1999 and end on the tenth anniversary of the CLOSING. This
         Agreement shall renew for a twelve-month period following the tenth
         anniversary of the Closing, and on each anniversary of the Closing
         thereafter (each a "renewal date"), upon the affirmative agreement of
         the parties.



                                                                         Page 18
<PAGE>   19

11.      Termination and Default.

         (a)      Termination. In addition to Advance Paradigm's right under
                  Section 8(c) hereof, this Agreement may be terminated as
                  follows:

                  (i)      Upon the mutual written consent of the parties
                           hereto.

                  (ii)     Advance Paradigm may terminate this Agreement at any
                           time in the event of a material default by Client.
                           Such termination shall be effective sixty (60) days
                           after receipt by Client of written notice specifying
                           the default, unless the default is cured before the
                           end of the sixty-day period.

                  (iii)    Client may deliver three (3) months' written notice
                           to Advance Paradigm that identifies any material and
                           persistent failure to process claims for the FHS
                           Affiliated Plans (the "Performance Notice"). As soon
                           as reasonably possible following receipt of such
                           notice, the parties will meet to discuss in good
                           faith the identified issues and develop a plan for
                           resolution. During the three (3) month period, both
                           parties shall provide good faith cooperation in
                           resolving the identified issues. If, within two (2)
                           months of delivery of the Performance Notice, Client
                           determines in its good faith business judgment that
                           the issues have not been resolved, Client shall
                           deliver written notice of its intent to terminate
                           this Agreement with respect to claims processing
                           services, as of the end of the three (3)-month period
                           if the issues are not resolved during the final
                           month. In such termination notice, the party shall
                           specify in writing any additional remedial actions it
                           believes need to be taken to remedy the continuing
                           breach. Advance Paradigm shall have opportunity to
                           cure, to Client's reasonable satisfaction, the
                           identified issues during this three (3)-month period,
                           and such cure shall cancel the termination notice
                           previously delivered. Termination pursuant to this
                           clause (iii) shall only apply to the claims
                           processing services, and Client shall be released
                           from the applicable "Exclusivity" obligations set
                           forth in Section 12 hereof applicable to claims
                           processing services.

                  (iv)     Upon written notice delivered to Advance Paradigm at
                           least 180 days prior to the fifth anniversary of this
                           Agreement, FHS may terminate this Agreement effective
                           on the fifth anniversary hereof provided FHS pays to
                           Advance Paradigm in cash an amount equal to the
                           Network Access Fees and Formulary/Rebate
                           Administrative Fees that would have been due to
                           Advance Paradigm had this Agreement remained in
                           effect for twelve (12) additional months, calculated
                           by annualizing such fees based upon the month in
                           which such termination occurs, but in no event less
                           than $8,886,000. At the sixth anniversary of this
                           Agreement or any time thereafter, upon written notice
                           delivered to Advance Paradigm at least 180 days prior
                           to the effective date of termination, FHS may
                           terminate this Agreement at any time upon payment in
                           cash to Advance Paradigm of $2 million. The payments
                           contemplated by this Section 11(a)(iv) are defined as
                           the "Early Termination Payments."



                                                                         Page 19

                  (v)      Following a Change of Control of Advance Paradigm,
                           upon 180 days written notice, FHS may terminate this
                           Agreement effective on or after the fifth
                           anniversary, and no Early Termination Payment will be
                           due; provided that this provision shall not apply if
                           there is a Change of Control of FHS at any time prior
                           to the effective date of such early termination. In
                           addition, if Advance Paradigm is acquired by any
                           company a substantial portion of whose business
                           directly competes with FHS' for health insurance
                           services, FHS may terminate this Agreement with
                           respect to claims processing and/or mail service
                           (including termination of any payment obligation for
                           such services) and network management services,
                           provided that all other terms of this Agreement will
                           remain in full force and effect (including Network
                           Access Fees and Formulary/Rebate Administrative
                           Fees). In the event of a Change of Control of FHS,
                           the FHS Successor shall not be required to utilize
                           Advance Paradigm as its vendor for pharmacy benefit
                           services, other than for the business attributable to
                           FHS and the FHS Affiliated Plans at the time of the
                           acquisition or business that would have been
                           attributable to FHS and the FHS Affiliated Plans as
                           if the acquisition had not occurred; provided, that
                           the terms, conditions and payment obligations of
                           Client under this Agreement shall become the
                           obligations of such FHS Successor.

                           In the event this Agreement terminates pursuant to
                           this Section 11(a)(v), Advance Paradigm, or its
                           successor, shall provide the FHS Affiliated Plans
                           with reasonable assistance to transition all Eligible
                           Members.

                  (vi)     In the event any governmental or regulatory agency or
                           body having jurisdiction over an FHS Affiliated Plan
                           notifies such Plan that Advance Paradigm shall not be
                           permitted to provide all or part of the PBM Services
                           set forth under this Agreement to such Plan, this
                           Agreement shall terminate as to such services for
                           such Plan unless Advance Paradigm is able to satisfy
                           the concerns of and obtain approval from such
                           governmental or regulatory body. Such Plan agrees to
                           provide reasonable assistance to Advance Paradigm in
                           responding to any such notification. Under such
                           circumstances, the minimum payment for claims
                           processing services set forth in Exhibit D shall be
                           equitably adjusted to account for any material change
                           in claims processing volume as a consequence thereof.

                  (vii)    This Agreement shall terminate immediately in the
                           event Advance Paradigm becomes insolvent or is
                           generally unable to perform because of its financial
                           condition.



                                                                         Page 20

         (b)      Effect of Termination.

                  (i)      Except as specifically set forth in Section
                           11(a)(iv), termination of this Agreement or Change of
                           Control of FHS shall not restrict or limit the
                           obligation of FHS (or any successor), to continue to
                           make, if applicable, through the tenth anniversary of
                           the Closing, the Formulary/Rebate Payments and the
                           Network Access Payments, except as otherwise provided
                           herein.

                  (ii)     In the event either Advance Paradigm or Client
                           terminate this Agreement in accordance with the terms
                           of Section 11(a), all unfulfilled payment obligations
                           for any of the services provided herein shall be paid
                           within thirty (30) days of the effective date of such
                           termination.

         (c)      Termination of Specific Services.

                  (i)      Termination of Section 3. Upon 180 days written
                           notice, either party may terminate Section 3 of this
                           Agreement. Upon the effective date of such
                           termination, the parties shall be released from their
                           respective obligations under Section 3, and Client
                           shall be released from the "Exclusivity" obligations
                           applicable to formulary/rebate services set forth in
                           Section 12 hereof. Upon termination of Section 3 by
                           FHS, FHS (or any FHS Successor) shall be required to
                           pay Advance Paradigm, on the date of termination and
                           on each anniversary thereof through the term of this
                           Agreement unless earlier terminated pursuant to
                           Section 11(a)(iv), an amount equal to the
                           Formulary/Rebate Administrative Fees that would have
                           been due to Advance Paradigm had this Agreement
                           remained in effect for twelve (12) additional months,
                           calculated by annualizing such fees based upon the
                           month in which such termination occurs (the "Rebate
                           Termination Payments"). At FHS' election, it may pay
                           such amount in a lump sum. Upon payment by FHS to
                           Advance Paradigm of the Early Termination Payment
                           under Section 11(a)(iv) of this Agreement, FHS shall
                           no longer be required to make additional Rebate
                           Termination Payments. In the event either party
                           terminates this provision, the parties will cooperate
                           and make best efforts to ensure that the Drug
                           Manufacturer Agreements remain in full force and
                           effect for both parties following the effective date
                           of termination.

                  (ii)     Termination of Section 4(a)-(c). Client may deliver
                           three (3) months' written notice to Advance Paradigm
                           that identifies any material and persistent failure
                           to manage the Primary Network or otherwise meet the
                           obligations set forth in Section 4(a)-(c) (the
                           "Network Termination Notice"). For purposes of this
                           Section 11(c)(ii), the failure to provide FHS and the
                           FHS Affiliated Plans the best available rates, as
                           reasonably determined by FHS, shall constitute a
                           material and persistent failure to meet the
                           obligations of Section 4(a)-(c). As soon as
                           reasonably possible 


                                                                         Page 21
<PAGE>   22

                           following receipt of such notice, the parties will
                           meet to discuss in good faith the identified issues
                           and develop a plan for resolution. During the three
                           (3) month period, both parties shall provide good
                           faith cooperation in resolving the identified issues.
                           If, within two (2) months of delivery of the Network
                           Termination Notice, Client determines in its good
                           faith business judgment that the issues have not been
                           resolved, Client shall deliver written notice of its
                           intent to terminate this Agreement with respect to
                           network management services, as of the end of the
                           three (3)-month period if the issues are not resolved
                           during the final month. In such termination notice,
                           FHS shall specify in writing any additional remedial
                           actions it believes need to be taken to remedy the
                           continuing breach and Advance Paradigm will have
                           opportunity to cure to the reasonable satisfaction of
                           FHS the identified issues during this three (3)-month
                           period, and such cure shall cancel the termination
                           notice previously delivered. Termination pursuant to
                           this Section 11(c)(ii) shall only apply to the
                           services specified in the notice. In the event of a
                           material change in the pricing in the industry, the
                           parties shall meet and confer regarding such changes;
                           and, if the parties are unable to agree on any change
                           in such rate, as contemplated in Section 4(a), FHS
                           shall have the right to terminate Sections 4(a)-(c)
                           upon 180 prior written notice.

                           Upon the effective date of such termination, the
                           parties will be released from their respective
                           obligations under Section 4(a) - (c) hereof, and
                           Client shall be released from the applicable
                           "Exclusivity" obligations set forth in Section 12
                           hereof applicable to retail pharmacy network
                           management. Upon termination of Sections 4(a)-(c),
                           Client shall be required to continue to pay Advance
                           Paradigm, on the date of termination and each
                           anniversary thereof through the term of this
                           Agreement unless earlier terminated pursuant to
                           Section 11(a)(iv), an amount equal to the Network
                           Access Fees that would have been due to Advance
                           Paradigm had this Agreement remained in effect for
                           twelve (12) additional months, calculated by
                           annualizing such fees based upon the month in which
                           such termination occurs ("Network Termination
                           Payments"). At FHS' election, it may pay such amount
                           in a lump sum. Upon payment by FHS to Advance
                           Paradigm of the Early Termination Payments set forth
                           in Section 11(a)(iv) of this Agreement, FHS shall no
                           longer be required to make any additional Network
                           Termination Payments.

12.      Restrictive Covenants and Exclusivity.

                  (a)      Non-compete. In order to assure that Advance Paradigm
                           will realize the benefits of the transactions
                           contemplated hereby, subject to FHS's right to
                           terminate this Agreement after five (5) years, during
                           the term of this Agreement, but in any event not less
                           than the five-year period following the Closing Date,
                           FHS and its affiliates shall not engage in pharmacy
                           claims processing, retail pharmacy network
                           management, mail service pharmacy, rebate management
                           or (subject to 


                                                                         Page 22

                           Section 3 of this Agreement) the negotiation and
                           performance of drug manufacturer agreements.
                           Notwithstanding the foregoing, (i) if the parties'
                           obligations regarding formulary management and drug
                           manufacturer agreements are terminated in accordance
                           with Section 11(c)(i) of this Agreement, then, so
                           long as FHS complies with Section 11(c)(i)) of this
                           Agreement, FHS may thereafter provide such services
                           for the FHS Affiliated Plans; and (ii) if FHS
                           releases Advance Paradigm from its obligations to
                           perform the retail pharmacy network management
                           services in accordance with Section 11(c)(ii) of this
                           Agreement, then, so long as FHS is in compliance with
                           Section 11(c)(ii) of this Agreement, FHS may
                           thereafter provide such services for the FHS
                           Affiliated Plans; both (i) and (ii) including
                           participation (which may include minority ownership
                           interests representing not more than twenty percent
                           (20%) of the equity or voting control) in cooperative
                           groups or alliances, provided FHS shall not market
                           such services to third parties. This section shall
                           not be deemed to be a limitation on providing
                           clinical services (including pharmacy formulary and
                           rebate management services in accordance with Section
                           3 of this Agreement) to the FHS Affiliated Plans and
                           FHS's contracting medical groups, or the disease
                           management services offered by FHS, or otherwise
                           limit FHS or any Affiliate from undertaking
                           activities relating to the processing and payment of
                           medical claims generally as a payor of such claims.

         (b)      Exclusivity. Client hereby grants Advance Paradigm during the
                  term of this Agreement, and any renewals hereof, the exclusive
                  right to provide PBM Services to Client, including without
                  limitation formulary/rebate services, mail service subject to
                  Section 5(a), claims adjudication and retail pharmacy network
                  management. Client further agrees that, except as set forth in
                  Section 3 hereof, during the term of this Agreement, it will
                  not negotiate, contract, or agree with any drug manufacturer
                  for the purpose of obtaining drug Rebates. The foregoing
                  notwithstanding, if either party terminates Section 3 pursuant
                  to Section 11(c)(i) or Section 4 (a)-(c) pursuant to Section
                  11(c)(ii), FHS may thereafter provide or otherwise obtain from
                  a third party such terminated services to the FHS Affiliated
                  Plans, which may include FHS' participation in cooperative
                  groups or alliances (including minority ownership
                  participation representing not more than twenty percent (20%)
                  of the equity or voting control), provided FHS is not
                  marketing such services to third parties. The parties
                  acknowledge and agree that the intended purpose of this
                  provision is to provide for the exclusive services of Advance
                  Paradigm for the Pharmacy Benefits of FHS and the FHS
                  Affiliated Plans, including enrollees, employer groups, and
                  other payors, enrolled with Client in the ordinary course of
                  business.

                  (i)      This Section 15(b) shall not preclude FHS from
                           participating in formulary/rebate services, in
                           accordance with Section 3 and Exhibit C.

                  (ii)     The parties agree that certain clients, potential
                           clients or product lines of FHS or its FHS Affiliated
                           Plans, such as under the CHAMPUS program, may have
                           separate operational requirements relating to
                           pharmacy benefits. 


                                                                         Page 23
<PAGE>   24

                           FHS and the FHS Affiliated Plans shall be free to
                           enter into agreements with such clients in
                           conformance with such client's request; provided,
                           however, that prior to entering into any agreement
                           that includes any or all of the services that are
                           substantially the same as any of the PBM Services
                           provided hereunder, FHS shall first provide Advance
                           Paradigm with the opportunity to participate in such
                           program on terms and conditions no less favorable
                           than FHS could obtain from any third party provider
                           of such services.

                  (iii)    The provisions of this Section 12 shall not apply to
                           the provision of pharmacy services through the
                           Internet; provided that Advance Paradigm shall have
                           the exclusive right to fulfill the mail order
                           pharmacy service requirements of FHS' web site. The
                           parties shall work together to develop pharmacy
                           related Internet applications for FHS.

         (c)      Limitations on Restrictive Covenants. Section 12 shall not be
                  deemed to be a limitation on (i) providing clinical services
                  (including pharmacy formulary and rebate management services
                  in accordance with Section 3 of this Agreement) to the FHS
                  Affiliated Plans or FHS' contracting medical groups, or (ii)
                  the disease management services offered by FHS, or (iii)
                  otherwise limit FHS or any Affiliate from undertaking
                  activities relating to the processing and payment of medical
                  claims generally as a payor of such claims. Further, nothing
                  contained in this Section 12 shall limit any FHS Successor
                  from owning and operating any business (or line of business),
                  for the benefit of the enrollees of the FHS Successor or third
                  parties with whom the FHS Successor contracts, which would
                  otherwise be construed as violating the provisions of this
                  Section 12; provided that the FHS Successor shall be bound to
                  this Section 12 with respect to the business of FHS and the
                  FHS Affiliated Plans; and provided further that, except as
                  expressly otherwise stated herein, all terms, conditions and
                  obligations of this Agreement shall become the obligations of
                  any FHS Successor. Advance Paradigm and the FHS Successor
                  shall use their respective best efforts to agree on the
                  allocation of enrollees between FHS and the FHS Successor that
                  are subject to this provision. To the extent that FHS acquires
                  any managed care company that has an ownership in or otherwise
                  provides services that would conflict with this provision, the
                  provision shall not apply to the enrollees of such managed
                  care organization as of the effective date of such
                  acquisition; provided that the provisions of this Section 12
                  shall continue to apply to any and all current and additional
                  Pharmacy Benefit business of the FHS Affiliated Plans.
                  Further, in the event that such acquired managed care company
                  has, in place, any agreements with third parties that would
                  conflict with or otherwise violate the terms of this
                  Agreement, such other agreements shall continue in force until
                  the first opportunity on which such agreements may be
                  terminated by their terms without any financial penalty to be
                  incurred by such acquired organization or FHS. In addition,
                  prior to consummating any acquisition of a managed care
                  company that has an ownership interest in or otherwise provide
                  services that shall conflict with this Section 12, FHS will
                  notify Advance Paradigm of such acquisition, and FHS and
                  Advance Paradigm shall engage in good faith negotiations
                  regarding cooperative efforts with such entity, including
                  Advance Paradigm's opportunity to acquire such business.



                                                                         Page 24
<PAGE>   25

         (d)      Notwithstanding anything contained herein to the contrary, in
                  the event of a breach or threatened breach of the covenants
                  contained in this Section 12, Advance Paradigm may, in
                  addition to any other available remedies, be entitled to an
                  injunction enjoining FHS and its Affiliates or any person or
                  persons acting for or with FHS in any capacity whatsoever from
                  violating any of the terms herein, in accordance with
                  applicable law regarding the award of an equitable remedy.

13.      Indemnification. Each party and its officers, directors, employees,
         agents, successors and assigns (each an "Indemnitee") shall be
         indemnified and held harmless by the other party (the "Indemnifying
         Party") against any and all claims, loss, damage, costs and expenses
         ("Loss"), including, without limitation, attorneys' fees and expenses,
         actually incurred by any Indemnitee arising out of or resulting from
         the actions or omissions of the Indemnifying Party.

14.      Audit.

         (a)      Audits of Eligible Members and Business Records. Client shall
                  have the right to inspect and audit, or cause to be inspected
                  and audited, the books and records of Advance Paradigm which
                  directly relate to billings made to Client for claims
                  reimbursement. Advance Paradigm shall have the right to
                  inspect and audit, or cause to be inspected and audited, the
                  books and records of Client directly relating to the validity
                  of the drug utilization data. Client and Advance Paradigm
                  shall fully cooperate with representatives of each other and
                  with independent accountants hired by either party to conduct
                  any such inspection or audit. Such audits shall be at the
                  auditing party's sole expense and shall only be made during
                  normal business hours, following fifteen (15) days written
                  notice, and without undue interference to the audited party's
                  business activity. If, after completion of the audit under
                  this Section 14(a), the audit reveals a discrepancy in the
                  results of the audit and the previous calculations of the
                  audited party, then the auditing party shall deliver written
                  notice which sets forth in reasonable detail the basis of such
                  discrepancy. The parties shall use reasonable efforts to
                  resolve the discrepancy within 30 days following delivery of
                  such notice, and such resolution shall be final, binding and
                  conclusive upon the parties hereto. If Advance Paradigm and
                  Client are unable to reach a resolution within such 30-day
                  period, the parties shall resolve such dispute in accordance
                  with Section 18 hereof.

         (b)      Payment of Discrepancies. Upon a final and conclusive
                  determination of a discrepancy revealed by an audit procedure
                  under this Section 14, the party which owes money shall pay
                  such sums to the other party within fifteen (15) days of the
                  delivery of the conclusive audit findings.



                                                                         Page 25

15.      Limitation of Liability.

         ADVANCE PARADIGM RELIES ON MEDI-SPAN OR INDUSTRY COMPARABLE DATABASES
         IN PROVIDING CLIENT AND ELIGIBLE MEMBERS WITH DRUG UTILIZATION REVIEW
         SERVICES. ADVANCE PARADIGM HAS UTILIZED DUE DILIGENCE IN COLLECTING AND
         REPORTING THE INFORMATION CONTAINED IN THE DATABASES AND HAS OBTAINED
         SUCH INFORMATION FROM SOURCES BELIEVED TO BE RELIABLE. ADVANCE
         PARADIGM, HOWEVER, DOES NOT WARRANT THE ACCURACY OF REPORTS, ALERTS,
         CODES, PRICES OR OTHER DATA CONTAINED IN THE DATABASES. THE CLINICAL
         INFORMATION CONTAINED IN THE DATABASES AND THE FORMULARY IS INTENDED AS
         A SUPPLEMENT TO, AND NOT A SUBSTITUTE FOR, THE KNOWLEDGE, EXPERTISE,
         SKILL, AND JUDGMENT OF PHYSICIANS, PHARMACISTS, OR OTHER HEALTH-CARE
         PROFESSIONALS INVOLVED IN ELIGIBLE MEMBERS' CARE. THE ABSENCE OF A
         WARNING FOR A GIVEN DRUG OR DRUG COMBINATION SHALL NOT BE CONSTRUED TO
         INDICATE THAT THE DRUG OR DRUG COMBINATION IS SAFE, APPROPRIATE OR
         EFFECTIVE IN ANY ELIGIBLE MEMBER.

16.      Confidentiality.

         (a)      Confidential and Proprietary Information. Client and Advance
                  Paradigm each recognize and acknowledge that, by receipt and
                  possession of certain information relating to the business
                  operations of the other, each will discover certain of the
                  other's confidential and proprietary information, skills,
                  know-how, technical expertise, and methods. This confidential
                  and proprietary information includes, but is not limited to:
                  (a) the terms of this Agreement, (b) the terms of each
                  parties' agreements with drug manufacturers, (c) the Drug
                  Manufacturer Agreements, and (d) trade secrets relating to the
                  operations of the PBM Services. Each party acknowledges and
                  agrees that such information is confidential, valuable and
                  proprietary to the business of the other party, and that each
                  party's success and ability to compete depends on keeping such
                  information confidential. Each party hereto covenants and
                  agrees not to, directly or indirectly, and agrees to cause its
                  officers, directors, employees, agents and affiliates not to,
                  use, publish, disseminate or otherwise disclose, any of the
                  other party's confidential or proprietary information now or
                  later possessed by each, without prior written consent of the
                  other party. Advance Paradigm and Client acknowledge that any
                  violation or breach of confidentiality would cause irreparable
                  harm and that such harm cannot be adequately compensated in
                  money damages. Advance Paradigm and Client agree that any such
                  violation or breach may be enjoined by any court of competent
                  jurisdiction, without waiver of any other right to claim
                  damages incurred by either Advance Paradigm or Client in
                  connection with such a violation.

         (b)      Confidentiality of Eligible Members. The parties shall
                  maintain the confidentiality of any patient identifiable
                  information in accordance with applicable laws and
                  regulations. Client shall insure that the release of patient
                  identifiable information to 


                                                                         Page 26
<PAGE>   27

                  Advance Paradigm and Client is duly authorized. Upon receipt
                  of a validly issued subpoena, court or administrative order or
                  a request for information that is signed by an Eligible
                  Member, Advance Paradigm shall be entitled to release such
                  information in accordance with the subpoena, order or request.
                  Advance Paradigm shall be entitled to assume the genuineness
                  of all signatures, the authenticity of all such requests,
                  orders or subpoenas, the conformity of copies of such
                  requests, orders or subpoenas to the original and that the
                  persons executing such requests, orders and subpoenas have
                  full power and authority to deliver same.

17.      Regulatory and Other Approvals.

         (a)      Regulatory Approvals. Advance Paradigm understands and agrees
                  that this Agreement shall be effective for each FHS Affiliated
                  Plan in accordance with applicable state law. In the event any
                  governmental or regulatory agency with jurisdiction over a FHS
                  Affiliated Plan denies approval for this Agreement and such
                  approval is required under applicable state law, this
                  Agreement shall not be effective with respect to the services
                  identified by the regulatory body, and shall not apply to such
                  FHS Affiliated Plan unless Advance Paradigm is able to satisfy
                  the concerns of and obtain approval of such governmental or
                  regulatory body within the applicable time. FHS agrees to
                  cause such FHS Affiliated Plan to provide reasonable
                  assistance to Advance Paradigm in responding to any such
                  notification. In the event that Advance Paradigm is unable or
                  unwilling to satisfy such concerns, the provisions of Section
                  12 shall be deemed inapplicable to such FHS Affiliate Plan or
                  FHS or IPS, to the extent that any of them provide or arrange
                  for the provision of such services to such FHS Affiliate Plan.

         (b)      Existence of Pre-existing Agreements/Approvals. Advance
                  Paradigm further understands that FHS, IPS or an FHS
                  Affiliated Plan has existing agreements, set forth in Schedule
                  17, to obtain services substantially similar to the PBM
                  Services (or any of them) provided hereunder. To the extent
                  such agreement may not be terminated without breach by the FHS
                  party, such agreement may continue in force without being
                  construed as a violation of any provision of this Agreement
                  until such time as the agreement may be terminated or
                  otherwise expires without financial penalty to the FHS party.

18.      Binding Arbitration. Advance Paradigm and FHS agree to meet and confer
         in good faith to resolve any problems or disputes that may arise under
         this Agreement. Such good faith meeting and conference shall be a
         condition precedent to the filing of any arbitration demand by either
         party. In addition, should the parties, prior to submitting a dispute
         to arbitration, desire to utilize other impartial dispute settlement
         techniques such as mediation or fact-finding, a joint request for such
         services may be made to the American Arbitration Association ("AAA") or
         Judicial Arbitration and Mediation Services ("JAMS"), or the parties
         may initiate such other procedures as they may mutually agree upon at
         such time.



                                                                         Page 27
<PAGE>   28

         (a)      The parties further agree that any controversy or claim
                  arising out of or relating to this Agreement, or the breach
                  thereof, whether involving a claim in tort, contract, or
                  otherwise, shall be settled by final and binding arbitration,
                  upon the motion of either party, to arbitration under the
                  appropriate rules of the AAA or JAMS, as agreed by the
                  parties. The arbitration shall be conducted by a single,
                  neutral arbitrator who is licensed to practice law. The
                  written demand shall contain a detailed statement of the
                  matter and facts and include copies of all related documents
                  supporting the demand.

         (b)      All such arbitration proceedings shall be administered by the
                  AAA or JAMS, as agreed by the parties; however, the arbitrator
                  shall be bound by applicable state and federal law, and shall
                  issue a written opinion setting forth findings of fact and
                  conclusions of law. The parties agree that the decision of the
                  arbitrator shall be final and binding as to each of them.
                  Judgment upon the award rendered by the arbitrator may be
                  entered in any court having jurisdiction. The arbitrator shall
                  have no authority to make material errors of law or to award
                  punitive damages or to add to, modify, or refuse to enforce
                  any agreements between the parties. The arbitrator shall make
                  findings of fact and conclusions of law and shall have no
                  authority to make any award which could have been made by a
                  court of law. The party against whom the award is rendered
                  shall pay any monetary award and/or comply with any other
                  order of the arbitrator within sixty (60) days of the entry of
                  judgment on the award.

         (c)      In all cases submitted to arbitration, the parties agree to
                  share equally the administrative fee as well as the
                  arbitrator's fee, if any, unless otherwise assessed by the
                  arbitrator. The administrative fees shall be advanced by the
                  initiating party subject to final apportionment by the
                  arbitrator in this award.

         (b)      Binding Nature and Assignment. This Agreement shall be binding
                  upon and inure to the benefit of the parties hereto, together
                  with any other health benefit plan acquired by FHS or its
                  affiliates during the term hereof, and the FHS Successors,
                  except with respect to FHS successors as specifically set
                  forth herein.

         (c)      Assignment. Neither party may assign this Agreement without
                  the prior written consent of the other; provided, however,
                  that Advance Paradigm may transfer or assign its rights and
                  obligations under this Agreement, to any affiliate and Client
                  may transfer its rights and obligations hereunder to an FHS
                  Successor, and provided further that no such assignment shall
                  have the effect of releasing such party from any of its
                  obligations under this Agreement.

         (d)      Entire Agreement. This Agreement contains all the terms and
                  conditions agreed upon by the parties with regard to the
                  subject matter herein, and supersedes all prior
                  understandings, writings, proposals, representations, or
                  communications, oral or written, of the parties hereto. This
                  Agreement may not be modified, amended or changed except by a
                  written agreement signed by the parties.

         (e)      Authority. Advance Paradigm and Client warrant that each has
                  full power and authority to enter into and perform this
                  Agreement, and the person signing this Agreement on behalf of
                  each party certifies that such person has been properly
                  authorized and empowered to enter into this Agreement on
                  behalf of such party.

         (f)      Non-Solicitation of Employees. During the term of this
                  Agreement, and for a period of one (1) year thereafter,
                  neither party shall, without the prior written consent of the
                  other party, knowingly solicit for employment any employees of
                  the other party.



                                                                         Page 29
<PAGE>   30

         (g)      Non-Waiver. The failure of either party to insist, in any one
                  or more instances, upon performance of any of the terms,
                  covenants or conditions of this Agreement shall not be
                  construed as a waiver or a relinquishment of any right or
                  claim granted or arising hereunder or of the future
                  performance of any such term, covenant, or condition, and such
                  failure shall in no way affect the validity of this Agreement
                  or the rights and obligations of the parties hereunder.

         (h)      Relationship of Parties. This Agreement shall not constitute
                  or otherwise imply a joint venture, pooling arrangement,
                  partnership or formal business organization of any kind. Both
                  parties shall be considered independent contractors and
                  neither party shall be considered an agent of the other. Under
                  no circumstances shall employees of one party be deemed the
                  employees of the other party.

         (i)      Force Majeure. Neither party shall be liable for any failure
                  or delay in performing all or part of its obligations under
                  the terms of this Agreement resulting from unavailability of
                  pharmaceuticals, legislative action, war, acts of any person
                  engaged in a subversive activity, sabotage, riot, strikes,
                  slow-downs, lock-outs, or labor stoppage, freight embargoes,
                  fires, explosions, flood, earthquake or other acts of God,
                  failure of electrical power or telecommunications services
                  (other than as a result of a Y2K failure of Advance Paradigm)
                  or by reason of the judgment, filing or order of any court or
                  agency of competent jurisdiction occurring subsequent to the
                  signing of this Agreement, or any other circumstances beyond
                  its control; provided, however, that any such action is not as
                  a result of the negligence of the party seeking to be excused
                  from performance.

         (j)      Authority of Advance Paradigm. Client acknowledges that it has
                  the sole authority to control and administer the Plan. Client
                  further acknowledges that Advance Paradigm is engaged to
                  perform the services under this Agreement as an independent
                  contractor and not as a fiduciary of the Plan or as an
                  employee or agent of Client, or any Plan contract
                  administrator. Nothing in this Agreement shall be construed or
                  deemed to confer upon Advance Paradigm any responsibility for
                  or control over the terms or validity of the Plan. Advance
                  Paradigm shall have no final discretionary authority over or
                  responsibility for the Plan's administration. Further, because
                  Advance Paradigm is not an insurer, plan sponsor, third party
                  administrator, plan contract administrator, or a provider of
                  health services to Eligible Members, Advance Paradigm shall
                  have no responsibility for (i) any funding of Plan benefits;
                  (ii) any insurance coverage relating to Client or any Plan
                  contract administrator, the Plan or Eligible Members; or (iii)
                  the nature or quality of professional health services rendered
                  to Eligible Members.

         (k)      Survival. Should any part, term or condition of this Agreement
                  be declared illegal or unenforceable or in conflict with any
                  other laws, the remaining provisions shall be valid and not
                  affected thereby.



                                                                         Page 30
<PAGE>   31

         (l)      Counterparts. This Agreement may be executed in any number of
                  counterparts, each of which shall be deemed an original and
                  all of which taken together shall constitute one and the same
                  instrument.

         (m)      Headings and Interpretation. The headings of the various
                  sections of this Agreement are inserted for convenience only
                  and do not, expressly or by implication, limit, define or
                  extend the specific terms of the section so designated.

         (n)      Departments of Insurance. The parties acknowledge that each
                  party is subject to the statutes and regulations in the states
                  in which this Agreement will be performed. The parties
                  acknowledge that, and shall comply with, the laws and
                  regulations of several states permitting Departments of
                  Insurance, Departments of Health, and Departments of
                  Corporations to have access to Advance Paradigm's books and
                  records relating to this Agreement for purpose of examination,
                  audit and inspection, subject to confidentiality obligations.

         (o)      Further Assurances. From time to time upon request and without
                  further consideration, the parties hereto shall, and shall
                  cause their subsidiaries, to execute, deliver or acknowledge
                  such documents and do such further acts as the other party
                  hereto may reasonably require to effectuate its obligations
                  contemplated by this Agreement.

         (p)      Fraud and Abuse. To the knowledge of Advance Paradigm, Advance
                  Paradigm and its respective executive officers and directors
                  have not (a) engaged in any activities which are prohibited
                  under 42 U.S.C. Section 1320a-7 (exclusionary authority) or
                  Section 1320a-7a (civil monetary penalties), or the
                  regulations promulgated pursuant to such statutes, or under
                  corresponding provisions of any applicable state law or
                  regulation, or (b) knowingly and willfully engaged in any
                  activities which are prohibited under 42 U.S.C. Section
                  1320a-7b (false claims and anti-kickback), or the regulations
                  promulgated pursuant to such statute, or under corresponding
                  provisions of any applicable state law or regulation, or (c)
                  engaged in any activities which are prohibited under any state
                  law or regulation corresponding to (a) or (b) above. To the
                  knowledge of Advance Paradigm, persons who provide
                  professional services under agreements with any of Advance
                  Paradigm or its Affiliates have not been excluded from the
                  Medicare program or any state health care program under 42
                  U.S.C. Section 1320-7 and Advance Paradigm is not aware of any
                  pending or threatened exclusion action against such
                  professional persons.


                                                                         Page 31

         Section 2.01.     The Advances and the Swing Loans.

conditions set forth in this Agreement, to make Advances to the Borrower from
time to time on any Business Day during the period from the date of this
Agreement until the Maturity Date in an aggregate amount not to exceed at any
time outstanding (i) the amount set opposite such Bank's name on the signature

Assignment and Acceptance after the Effective Date, set forth for such Bank as
its Commitment in the Register maintained by the Agent pursuant to Section
9.06(b), as such amount may be reduced pursuant to Section 2.04 (such Bank's

Exposure at such time; provided that the aggregate principal amount of
outstanding Advances, plus the Letter of Credit Exposure, plus the aggregate
principal amount of outstanding Swing Loans shall never exceed $75,000,000.00.

               (i) On the terms and conditions set forth in this Agreement, the
         Agent may, in its discretion from time to time on any Business Day
         during the period from the date of this Agreement until the Maturity
         Date, make loans ("Swing Loans") under the Swing Note to the Borrower
         in an aggregate principal amount not to exceed $10,000,000.00
         outstanding at any time; provided, that the aggregate principal amount
         of outstanding Advances, plus the Letter of Credit Exposure, plus the
         aggregate principal amount of outstanding Swing Loans shall never
         exceed $75,000,000.00. Subject to the other provisions of this
         Agreement, the Borrower may from time to time borrow, prepay (in whole
         or in part and without premium or penalty) and reborrow Swing Loans.
         Except as provided in the following clause (ii), each Swing Loan and
         optional prepayment of a Swing Loan shall be made pursuant to telephone
         notice to the Agent given no later that 1:00 p.m. (Charlotte, North
         Carolina time) on the date of the proposed Swing Loan or prepayment,
         promptly confirmed by a completed and executed Notice of Swing Loan
         Request or Prepayment in the form of the attached Exhibit F telecopied
         to the Agent. The Agent will make the Swing Loan available to the
         Borrower, and the Borrower will make the prepayment available to the
         Agent, at the Borrower's account with the Agent.

              (ii) The Borrower shall repay the outstanding principal amount of
         the Swing Loans on the Maturity Date. The Borrower and the Banks agree
         that the Agent may request each Bank to pay, and upon such a request
         made in accordance with the following sentence each Bank shall pay, to
         the Agent such Bank's Pro Rata Share of all outstanding Swing Loans as
         a Base Rate Advance under such Bank's Commitment (a) on each Wednesday,
         or if such Wednesday is not a Business Day on the next Business Day
         after such Wednesday, on which the aggregate outstanding principal
         balance of all Swing Loans, after giving effect to all Swing Loans to
         be made on such day and notices of prepayments of Swing Loans given for
         such day, is greater than or equal to $3,000,000.00, (B) on any
         Business Day on which a Swing Loan has been outstanding for 14 or more
         days, and (C) upon written request from the Agent. In connection with
         any Advance to be made as contemplated by the foregoing sentence, the
         Agent shall give each Bank a notice to make a Base Rate Advance to the
         Borrower in the amount of its Pro Rata Share of the outstanding Swing
         Loans by 1:00 p.m. (Charlotte, North Carolina time) on the date the
         proposed Advances are to be made. All Advances made pursuant to each
         request made by the Agent pursuant to the foregoing sentence shall be
         considered to be a Borrowing, and the Borrower hereby irrevocably
         instructs the Agent to apply the proceeds of such Advances to the
         prepayment of the outstanding Swing Loans. Each Bank (including the
         Agent) shall make its Pro Rata Share of each such Borrowing available
         to the Agent in immediately available funds by 3 p.m. (Charlotte, North
         Carolina time) on the date requested.

             (iii) Upon the acceleration of the Maturity Date pursuant to
         Section 7.02 or 7.03, each Bank shall pay to the Agent such Bank's Pro
         Rata Share of all outstanding Swing Loans as a Base Rate Advance under
         such Bank's Commitment, but in no event shall any Bank be 


                                      -22-
<PAGE>   28

          obligated to fund more than its Commitment. Upon the date of such
          payment all accrued but unpaid interest on the Swing Note to such date
          shall be due and payable by the Borrower to the Agent.

         Section 2.02.     Method of Borrowing.

on the third Business Day before the date of the proposed Borrowing, in the case
of a Eurodollar Rate Advance or (ii) 10:00 a.m. (Charlotte, North Carolina time)

Advances, the Agent shall promptly notify each Bank of the applicable interest
rate under Section 2.06(b). Each Bank shall (i) in the case of all Borrowings
other than Borrowings made on the same day as the day the Notice of Borrowing is
received, before 11:00 a.m. (Charlotte, North Carolina time) on the date of such
Borrowing and (ii) in the case of Borrowings made on the same day as the date of
the Notice of Borrowing, before 2:00 p.m. (Charlotte, North Carolina time), make
available for the account of its Applicable Lending Office to the Agent at its
address referred to in Section 9.02, or such other location as the Agent may
specify by notice to the Banks, in same day funds, such Bank's Pro Rata Share of
such Borrowing. After the Agent's receipt of such funds and upon fulfillment of
the applicable conditions set forth in Article III, the Agent will make such
funds available to the Borrower at its account with the Agent.

         (b) Conversions and Continuations. In order to elect to Convert or
Continue an Advance under this Section, the Borrower shall deliver an
irrevocable Notice of Conversion or Continuation to the Agent at the Agent's
office no later than 11:00 a.m. (Charlotte, North Carolina time) (i) the
Business Day of the proposed conversion date in the case of a Conversion to a
Base Rate Advance and (ii) at least three Business Days in advance of the
proposed Conversion or Continuation date in the case of a Conversion to, or a
Continuation of, a Eurodollar Rate Advance. Each such Notice of Conversion or
Continuation shall be in writing or by telex or telecopier, confirmed
immediately in writing specifying (i) the requested Conversion or Continuation
date (which shall be a Business Day), (ii) the amount, Type of the Advance to be
Converted or Continued, (iii) whether a Conversion or Continuation is requested,
and if a Conversion, into what Type of Advance, and (iv) in the case of a

Continuation under this paragraph, the Agent shall provide each Bank with a copy
thereof and, in the case of a Conversion to or a Continuation 


                                      -23-
<PAGE>   29

of a Eurodollar Rate Advance, notify each Bank of the applicable interest rate
under Section 2.06(b). For purposes other than the making of deemed
representations and warranties pursuant to Section 3.02, the portion of Advances
comprising part of the same Borrowing that are converted to Advances of another
Type shall constitute a new Borrowing.

         (c) Certain Limitations. Notwithstanding anything in paragraphs (a) and
(b) above:

               (i) at no time shall there be more than five Interest Periods
         applicable to outstanding Eurodollar Rate Advances;

              (ii) the Borrower may not select Eurodollar Rate Advances for any
         Borrowing at any time when a Default has occurred and is continuing;

             (iii) (A) if any Bank shall, at least one Business Day before the
         date of any requested Borrowing, notify the Agent that the introduction
         of or any change in or in the interpretation of any law or regulation
         makes it unlawful, or that any central bank or other governmental
         authority asserts that it is unlawful, for such Bank or its Applicable
         Lending Office to perform its obligations under this Agreement to make
         Eurodollar Rate Advances or to fund or maintain Eurodollar Rate
         Advances, the right of the Borrower to select Eurodollar Rate Advances
         for such Borrowing or for any subsequent Borrowing shall be suspended
         until such Bank shall notify the Agent that the circumstances causing
         such suspension no longer exist, and each Advance comprising such
         Borrowing shall be a Base Rate Advance, and (B) such Bank agrees to use
         commercially reasonable efforts (consistent with its internal policies
         and legal and regulatory restrictions) to designate a different
         Applicable Lending Office if the making of such designation would avoid
         the effect of this paragraph and would not, in the reasonable judgment
         of such Bank, be otherwise disadvantageous to such Bank;

              (iv) if the Agent is unable to determine the Eurodollar Rate for
         Eurodollar Rate Advances comprising any requested Borrowing, the right
         of the Borrower to select Eurodollar Rate Advances for such Borrowing
         or for any subsequent Borrowing shall be suspended until the Agent
         shall notify the Borrower and the Banks that the circumstances causing
         such suspension no longer exist, and each Advance comprising such
         Borrowing shall be a Base Rate Advance;

               (v) if the Majority Banks shall, at least one Business Day before
         the date of any requested Borrowing, notify the Agent that the
         Eurodollar Rate for Eurodollar Rate Advances comprising such Borrowing
         will not adequately reflect the cost to such Banks of making or funding
         their respective Eurodollar Rate Advances, as the case may be, for such
         Borrowing, the right of the Borrower to select Eurodollar Rate Advances
         for such Borrowing or for any subsequent Borrowing shall be suspended
         until the Agent shall notify the Borrower and the Banks that the
         circumstances causing such suspension no longer exist, and each Advance
         comprising such Borrowing shall be a Base Rate Advance; and



                                      -24-
<PAGE>   30

              (vi) if the Borrower shall fail to select the duration or
         continuation of any Interest Period for any Eurodollar Rate Advances in
         accordance with the provisions contained in the definition of Interest
         Period in Section 1.01 and paragraph (b) above, the Agent will
         forthwith so notify the Borrower and the Banks and such Advances will
         be made available to the Borrower on the date of such Borrowing as Base
         Rate Advances or, if an existing Advance, Convert into Base Rate
         Advances.

         (d)Treatment of Affected Loans. If the obligation of any Bank to make a
Eurodollar Rate Advance or to Continue, or to Convert Base Rate Advances into,
Eurodollar Rate Advance shall be suspended pursuant to Sections 2.02(c) or
2.07(d) (such Eurodollar Rate Advances being herein called "Affected Loans"),
such Bank's Affected Loans shall be automatically Converted into Base Rate
Advances on the last day(s) of the then current Interest Period(s) for Affected
Loans (or, in the case of a Conversion required by Section 2.02(c)(iii), on such
earlier date as such Bank may specify to the Borrower with a copy to the Agent)
and, unless and until such Bank gives notice as provided below that the
circumstances specified in Section 2.02(c) or 2.07(d) that gave rise to such
Conversion no longer exist:

               (i) to the extent that such Bank's Affected Loans have been so
         Converted, all payments and prepayments of principal that would
         otherwise be applied to such Bank's Affected Loans shall be applied
         instead to its Base Rate Advances; and

              (ii) all Loans that would otherwise be made or Continued by such
         Bank as Eurodollar Rate Advances shall be made or Continued instead as
         Base Rate Advances, and all Base Rate Advances of such Bank that would
         otherwise be Converted into Eurodollar Rate Advances shall be Converted
         instead into (or shall remain as) Base Rate Advances.

If such Bank gives notice to the Borrower (with a copy to the Agent) that the
circumstances specified in Section 2.02(c) or 2.07(d) that gave rise to the
Conversion of such Bank's Affected Loans pursuant to this Section 2.02(d) no
longer exist (which such Bank agrees to do promptly upon such circumstances
ceasing to exist) at a time when Eurodollar Rate Advances made by other Banks
are outstanding, such Bank's Base Rate Advances shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Rate Advances, to the extent necessary so that,
after giving effect thereto, all Eurodollar Rate Advances held by the Banks by
such Bank are held pro rata (as to principal amounts, Types, and Interest
Periods) in accordance with their respective Commitments.



                                      -25-
<PAGE>   31

         (e) Notices Irrevocable. Each Notice of Borrowing, Notice of Conversion
or Continuation, and Notice of Swing Loan Request or Prepayment shall be
irrevocable and binding on the Borrower.

         (f) Agent Reliance. Unless the Agent shall have received notice from a
Bank before the date of any Borrowing that such Bank will not make available to
the Agent such Bank's Pro Rata Share of such Borrowing, the Agent may assume
that such Bank has made its Pro Rata Share of such Borrowing available to the
Agent on the date of such Borrowing in accordance with paragraph (a) of this
Section 2.02 and the Agent may, in reliance upon such assumption, make available
to the Borrower on such date a corresponding amount. If and to the extent that
such Bank shall not have so made its Pro Rata Share of such Borrowing available
to the Agent, such Bank and the Borrower severally agree to immediately repay to
the Agent on demand such corresponding amount, together with interest on such
amount, for each day from the date such amount is made available to the Borrower
until the date such amount is repaid to the Agent, at (i) in the case of the
Borrower, the interest rate applicable on such day to Advances comprising such
Borrowing and (ii) in the case of such Bank, the Federal Funds Rate for such
day. If such Bank shall repay to the Agent such corresponding amount and
interest as provided above, such corresponding amount so repaid shall constitute
such Bank's Advance as part of such Borrowing for purposes of this Agreement
even though not made on the same day as the other Advances comprising such
Borrowing.

         (g) Bank Obligations Several. The failure of any Bank to make the
Advance to be made by it as part of any Borrowing shall not relieve any other
Bank of its obligation, if any, to make its Advance on the date of such
Borrowing. No Bank shall be responsible for the failure of any other Bank to
make the Advance to be made by such other Bank on the date of any Borrowing.

         (h) Notes. The indebtedness of the Borrower to each Bank resulting from
Advances owing to such Bank shall be evidenced by a Note of the Borrower payable
to the order of such Bank in substantially the form of Exhibit C.

         (i) Swing Note. The indebtedness of the Borrower to the Agent resulting
from Swing Loans owing to the Agent shall be evidenced by the Swing Note of the
Borrower payable to the order of the Agent in substantially the same form as
Exhibit K.

         (a) Commitment Fees. The Borrower agrees to pay to the Agent for the

equal to the Applicable Margin for Eurodollar Rate Advances and (ii) to the
Issuing Bank, a fee for each Letter of Credit of .125% per annum of the face
amount of such Letter of Credit. Each such fee shall be based on the maximum
amount available to be drawn under such Letter of Credit from the date of
issuance of the Letter of Credit until its Expiration Date and be payable
quarterly in arrears on the last day of each March, June, September, and

         Section 2.04.     Reduction of the Commitments.

Days' irrevocable notice to the Agent, to terminate in whole or reduce ratably

reduction shall be in the aggregate amount of not less than $3,000,000.00 and in
integral multiples of $1,000,000.00 in excess thereof, and (ii) in conjunction
with the prepayment of Advances required by Section 2.07(c)(ii), the Commitments
shall be reduced automatically upon the receipt of the cash proceeds from a
Nonordinary Course Asset Sale, by an amount equal to 50% of the Net Cash
Proceeds any Credit Party receives from such Nonordinary Course Asset Sale.

         (b) Any reduction or termination of the Commitments pursuant to this
Section 2.04 shall be permanent, with no obligation of the Banks to reinstate
such Commitments, and the commitment fees provided for in Section 2.03(a) shall
thereafter be computed on the basis of the Commitments, as so reduced.

         Section 2.05. Repayment. The Borrower shall repay the outstanding
principal amount of and all accrued and unpaid interest on each Advance on the
Maturity Date.

         Section 2.06. Interest. The Borrower shall pay interest on the unpaid
principal amount of each Advance made by each Bank from the date of such Advance
until such principal amount shall be paid in full and on the unpaid principal
amount of each Swing Loan made by the Agent from the date of such Swing Loan
until such Swing Loan shall be paid in full, at the following rates per annum:

         (a) Base Rate Advances and Swing Loans. For Base Rate Advances and for
Swing Loans, a rate per annum equal at all times to the lesser of (i) the Base
Rate in effect from time to time plus the Applicable Margin and (ii) the Maximum
Rate, payable in arrears on the last day of each calendar quarter.

         (b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate
Advance, a rate per annum equal at all times during the Interest Period for such
Advance to the lesser of (i) the Adjusted Eurodollar Rate for such Interest
Period plus the Applicable Margin and (ii) the Maximum Rate, payable on the last
day of such Interest Period, and, in the case of six-month Interest Periods, on
the day which occurs during such Interest Period three months from the first day
of such Interest Period.

         (c) Default Rate. After the occurrence and during the continuance of an
Event of Default and after written notice from the Agent to the Borrower that
the Majority Banks have elected to charge the default rate, all principal of the
Advances and the Swing Loans, the Reimbursement Obligations, and past due
interest shall bear interest from the later of the date of the occurrence of the
Event of Default that is continuing and another date after the occurrence of
such Event of Default indicated in such notice until the earlier of the date
such Event of Default is cured or waived and the date on which the Agent
notifies the Borrower in writing that the Majority Banks have elected to no
longer charge the default rate at a rate per annum equal to the lesser of (i)
the rate of interest otherwise applicable plus 2% and (ii) the Maximum Rate.

         Section 2.07.     Prepayments.

         (a) Right to Prepay. The Borrower shall have no right to prepay any
principal amount of any Advance except as provided in this Section 2.07. All
prepayments shall be without premium or penalty except as provided in Section
2.08. Subject to Section 7.07, unless the Borrower designates otherwise, all
prepayments shall be applied first to Swing Loans, then to Base Rate Borrowings,
then to Eurodollar Borrowings, in order of maturity.

         (b) Optional. The Borrower may elect to prepay any of the Advances,
after giving by 11:00 a.m. (Charlotte, North Carolina time) (i) in the case of
Eurodollar Rate Advances, at least three Business Days' or (ii) in case of Base
Rate Advances, same Business Day's prior written notice to the Agent stating the
proposed date and aggregate principal amount of such prepayment. If any such
notice is given, the Borrower shall prepay Advances comprising part of the same
Borrowing in 


                                      -28-
<PAGE>   34

whole or ratably in part in an aggregate principal amount equal to the amount
specified in such notice, together with accrued interest to the date of such
prepayment on the principal amount prepaid and amounts, if any, required to be
paid pursuant to Section 2.08 as a result of such prepayment being made on such
date; provided, however, that each partial payment shall be in an aggregate
amount not less than (i) in the case of Base Rate Advances, $500,000.00 and in
integral multiples of $100,000.00 in excess thereof and (ii) in the case of
Eurodollar Rate Advances, $3,000,000.00 and in integral multiples of
$1,000,000.00 in excess thereof.

         (c)       Mandatory.

               (i) On the date of each reduction of the aggregate Commitments
         pursuant to Section 2.04, the Borrower agrees to make a prepayment in
         respect of the outstanding amount of Advances to the extent, if any,
         that the aggregate unpaid principal amount of all Advances exceeds the
         Commitment, as so reduced.

              (ii) The Borrower shall repay the Advances by an amount equal to
         50% of Net Cash Proceeds from a Nonordinary Course Asset Sale that are
         not used within 120 days after the Borrower's or any of its
         Subsidiaries' receipt thereof to purchase assets used in the Borrower
         and its Subsidiaries business. Such repayments shall be made on the
         120th day after the date of receipt of such Net Cash Proceeds.

             (iii) The Borrower shall repay the Advances by an amount equal to
         100% of the Net Cash Proceeds any Credit Party receives from the sale
         of any capital stock (other than issuance under a warrant or option
         issued in the ordinary course or business) or the issuance of any debt
         securities. Such repayments shall be made promptly after the Borrower's
         or any of its Subsidiaries' receipt thereof.

              (iv) Each prepayment pursuant to this Section 2.07(c) shall be
         accompanied by accrued interest on the amount prepaid to the date of
         such prepayment and amounts, if any, required to be paid pursuant to
         Section 2.08 as a result of such prepayment being made on such date.

         (d) Illegality. If any Bank shall notify the Agent and the Borrower
that the introduction of or any change in or in the interpretation of any law or
regulation makes it unlawful, or that any central bank or other Governmental
Authority asserts that it is unlawful for such Bank or its Applicable Lending
Office to perform its obligations under this Agreement to maintain any
Eurodollar Rate Advances of such Bank then outstanding hereunder, (i) the
Borrower shall, no later than 11:00 a.m. (Charlotte, North Carolina time), (a)
if not prohibited by law or regulation to maintain such Eurodollar Rate Advances
for the duration of the Interest Period, on the last day of the Interest Period
for each outstanding Eurodollar Rate Advance or (B) if prohibited by law or
regulation to maintain such Eurodollar Rate Advances for the duration of the
Interest Period, on the


                                      -29-
<PAGE>   35

second Business Day following its receipt of such notice, prepay all of the
Eurodollar Rate Advances of all of the Banks then outstanding, together with
accrued interest on the principal amount prepaid to the date of such prepayment
and amounts, if any, required to be paid pursuant to Section 2.08 as a result of
such prepayment being made on such date, (ii) each Bank shall simultaneously
make a Base Rate Advance to the Borrower on such date in an amount equal to the
aggregate principal amount of the Eurodollar Rate Advances prepaid to such Bank,
and (iii) the right of the Borrower to select Eurodollar Rate Advances for any
subsequent Borrowing shall be suspended until the Bank which gave notice
referred to above shall notify the Agent that the circumstances causing such
suspension no longer exist. Each Bank agrees to use commercially reasonable
efforts (consistent with its internal policies and legal and regulatory
restrictions) to designate a different Applicable Lending Office if the making
of such designation would avoid the effect of this paragraph and would not, in
the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank.

         (e) Ratable Payments; Effect of Notice. Each payment of any Advance
pursuant to this Section 2.07 or any other provision of this Agreement shall be
made in a manner such that all Advances comprising part of the same Borrowing
are paid in whole or ratably in part. All notices given pursuant to this Section
2.07 shall be irrevocable and binding upon the Borrower.

         Section 2.08. Breakage Costs. Upon the request of any Bank, the
Borrower shall pay to such Bank such amount or amounts as shall be sufficient
(in the reasonable opinion of such Bank) to compensate it for any loss, cost, or
expense (excluding loss of anticipated profits) incurred by it as a result of:

         (a) Funding Losses. In the case of any Borrowing which the related
Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances,
the Borrower shall indemnify each Bank against any loss, out-of-pocket cost, or
expense incurred by such Bank as a result of any failure to fulfill on or before
the date specified in such Notice of Borrowing for such Borrowing the applicable
conditions set forth in Article III, including, without limitation, any loss
(excluding any loss of anticipated profits), cost, or expense incurred by reason
of the liquidation or redeployment of deposits or other funds acquired by such
Bank to fund the Eurodollar Rate Advance to be made by such Bank as part of such
Borrowing when such Eurodollar Rate Advance, as a result of such failure, is not
made on such date.

         (b) Prepayment Losses. If (i) any payment of principal of any 
Eurodollar Rate Advance is made other than on the last day of the Interest
Period for such Advance as a result of any voluntary prepayment, payment
pursuant to Section 2.07(d), the acceleration of the maturity of the Notes and
the Swing Note, or for any other reason or (ii) the Borrower fails to make a
principal or interest payment with respect to any Eurodollar Rate Advance on the
date such payment is due and payable, the Borrower shall, within 10 days of any
written demand sent by any Bank to the Borrower, pay to such Bank any amounts
required to compensate such Bank for any additional losses, out-of-pocket costs,
or expenses which it may reasonably incur as a result of such payment or
nonpayment, 


                                      -30-
<PAGE>   36

including, without limitation, any loss (excluding loss of anticipated profits),
cost, or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Bank to fund or maintain such Advance.
All such demands shall show in reasonable detail the calculation of such losses.

         Section 2.09.     Increased Costs and Reduced Return.

         (a) Eurodollar Rate Advances. If, after the date of this Agreement, the
adoption of any applicable law, rule, or regulation, or any change in any
applicable law, rule, or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Applicable Lending Office) with any request or
directive (whether or not having the force of law) of any such governmental
authority, central bank, or comparable agency:

                  (i) shall subject such Bank (or its Applicable Lending Office)
         to any tax, duty, or other charge with respect to any Eurodollar Rate
         Advances, its Notes, or its obligation to make Eurodollar Rate
         Advances, or change the basis of taxation of any amounts payable to
         such Bank (or its Applicable Lending Office) under this Agreement or
         its Notes in respect of any Eurodollar Rate Advances (other than
         franchise taxes or taxes imposed on the overall net income of such Bank
         by the jurisdiction in which such Bank has its principal office or such
         Applicable Lending Office);

                  (ii) shall impose, modify, or deem applicable any reserve,
         special deposit, assessment, or similar requirement (other than by way
         of imposition or increase of reserve requirements included in the
         Eurodollar Rate Reserve Percentage) relating to any extensions of
         credit or other assets of, or any deposits with or other liabilities or
         commitments of, such Bank (or its Applicable Lending Office), including
         the Commitments of such Bank hereunder; or

                  (iii) shall impose on such Bank (or its Applicable Lending
         Office) or on the London interbank market any other condition affecting
         this Agreement or its Notes or any of such extensions of credit or
         liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making, Converting into, continuing, or
maintaining any Eurodollar Rate Advances or to reduce any sum received or
receivable by such Bank (or its Applicable Lending Office) under this Agreement
or its Notes with respect to any Eurodollar Rate Advances, then the Borrower
shall pay to such Bank within three Business Days after written demand made by
such Bank such amount or amounts as will compensate such Bank for such increased
cost or reduction.



                                      -31-
<PAGE>   37

         (b) Capital Adequacy. If, after the date of this Agreement, any Bank
shall have determined that the adoption of any applicable law, rule, or
regulation regarding capital adequacy or any change therein or in the
interpretation or administration thereof by any governmental authority, central
bank, or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such governmental authority, central bank, or
comparable agency, has or would have the effect of reducing the rate of return
on the capital of such Bank or any corporation controlling such Bank as a
consequence of such Bank's obligations hereunder to a level below that which
such Bank or such corporation could have achieved but for such adoption, change,
request, or directive (taking into consideration its policies with respect to
capital adequacy), then from time to time within three Business Days after
written demand by such Bank the Borrower shall pay to such Bank such additional
amount or amounts as will compensate such Bank for such reduction.

         (c) Letters of Credit. If, after the date of this Agreement, the
adoption of any applicable law, rule, or regulation, or any change in any
applicable law, rule, or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation or administration thereof, or
compliance by the Issuing Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
governmental authority, central bank, or comparable agency:

                  (i) shall subject the Issuing Bank (or its Applicable Lending
         Office) to any tax, duty, or other charge with respect to any Letter of
         Credit issued by it or its obligation to issue Letters of Credit, or
         change the basis of taxation of any amounts payable to the Issuing Bank
         (or its Applicable Lending Office) under this Agreement in respect of
         any Letters of Credit issued by its (other than franchise taxes or
         taxes imposed on the overall net income of the Issuing Bank by the
         jurisdiction in which the Issuing Bank has its principal office or such
         Applicable Lending Office);

                  (ii) shall impose, modify, or deem applicable any reserve,
         special deposit, assessment, or similar requirement relating to any
         letters of credit or other assets of, or any deposits with or other
         liabilities or commitments of, the Issuing Bank (or its Applicable
         Lending Office); or

                  (iii) shall impose on the Issuing Bank (or its Applicable
         Lending Office) any other condition affecting the provision under this
         Agreement relating to Letters of Credit issued by it or its obligation
         to issue Letters of Credit;

and the result of any of the foregoing is to increase the cost to the Issuing
Bank (or its Applicable Lending Office) of issuing or maintaining, or being
obligated to issue, any Letters of Credit or to reduce any sum received or
receivable by the Issuing Bank (or its Applicable Lending Office) under this
Agreement or the Letters of Credit, then the Borrower shall within three
Business Days after written demand by such Bank pay to the Issuing Bank on
demand such amount or amounts as will compensate the Issuing Bank for such
increased cost or reduction.



                                      -32-
<PAGE>   38

         (d) Mitigation. Each Bank and the Issuing Bank shall promptly (but in
any event within 90 days after the occurrence of the event giving rise to such
right to compensation) notify the Borrower and the Agent of any event of which
it has knowledge which will entitle such Bank or the Issuing Bank to
compensation pursuant to this Section 2.09 and will designate a different
Applicable Lending Office if such designation will avoid the need for, or reduce
the amount of, such compensation and will not, in the reasonable judgment of
such Bank or the Issuing Bank, be otherwise disadvantageous to it. Any Bank or
the Issuing Bank claiming compensation under this Section 2.09 shall furnish to
the Borrower and the Agent a copy of the applicable law, rule, regulation or
directive and a statement setting forth the additional amount or amounts to be
paid to it hereunder which shall be conclusive in the absence of manifest error.
In determining such amount, such Bank and the Issuing Bank may use any
reasonable averaging and attribution methods.

         (e) Right to Replace. The Borrower shall have the right to replace each
Bank affected by a condition under Section 2.02(c)(iii) or (v), 2.07(d), or
2.09(a) or (b) for more than 30 days from the date such Bank was affected by
such condition (each such affected Bank, an "Affected Bank") with an Eligible
Assignee designated by the Borrower or by the Agent with the Borrower's consent.
Any replacement of a Bank pursuant to this paragraph shall be (i) made by the
Eligible Assignee's and the Affected Bank's entering into an Assignment and
Acceptance and by following the procedures in Section 9.06 for adding a Bank;
(ii) shall close within 10 days after the Agent's receipt of a notice of
election to replace such Bank from the Borrower; and (iii) shall only be made
upon the Affected Bank's being paid in full all principal, interest, and other
amounts owed to it as of the effective date of the replacement.

         (f) Nondiscrimination. No Bank or Issuing Bank may pass through to the
Borrower charges or costs under Section 2.08 and 2.09 which are not also passed
through by such Bank or Issuing Bank to other customers of such Bank or Issuing
Bank similarly situated and subject to documents providing for such pass
through.

         Section 2.10.     Payments and Computations.

         (a) Payments. All payments of principal, interest, and other amounts to
be made by the Borrower under this Agreement and the other Credit Documents
shall be made to the Agent in Dollars, without setoff, deduction, or
counterclaim.

         (b) Payment Procedures. The Borrower shall make each payment under this
Agreement and under the Notes not later than noon (Charlotte, North Carolina
time) on the day when due in Dollars to the Agent at the location referred to in
the Notes (or such other location as the Agent shall designate in writing to the
Borrower) in same day funds. The Agent will promptly thereafter, and in any
event prior to the close of business on the day any timely payment is made,
cause to be distributed like funds relating to the payment of principal,
interest or fees ratably (other than amounts payable solely to the Agent, the
Issuing Bank, or a specific Bank pursuant to Section 2.03(b), 2.03(c), 2.08,
2.09, 2.11, or 9.07) in accordance with each Bank's Pro Rata Share to the Banks
for the account of their respective Applicable Lending Offices, and like funds
relating to the payment of any other amount payable to any Bank or the Issuing
Bank to such Bank for the account of its Applicable Lending Office, in each case
to be applied in accordance with the terms of this Agreement.

         (c) Computations. All computations of interest based on the Base Rate,
the Eurodollar Rate, and the Federal Funds Rate and all computations of fees
shall be made by the Agent on the basis of a year of 360 days, in each case for
the actual number of days (including the first day, but excluding the last day)
occurring in the period for which such interest or fees are payable. Each
determination by the Agent of an interest rate shall be conclusive and binding
for all purposes, absent manifest error.

         (d) Non-Business Day Payments. Whenever any payment shall be stated to
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
provided, however, that if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

         (e) Agent Reliance. Unless the Agent shall have received written notice
from the Borrower prior to the date on which any payment is due to the Banks
that the Borrower will not make such payment in full, the Agent may assume that
the Borrower has made such payment in full to the Agent on such date and the
Agent may, in reliance upon such assumption, cause to be distributed to each
Bank on such date an amount equal to the amount then due such Bank. If and to
the extent the Borrower shall not have so made such payment in full to the
Agent, each Bank shall repay to the Agent forthwith on demand such amount
distributed to such Bank, together with interest, for each day from the date
such amount is distributed to such Bank until the date such Bank repays such
amount to the Agent, at the Federal Funds Rate for such day, but not in excess
of the Maximum Rate.

         Section 2.11.     Taxes.

         (a) No Deduction for Certain Taxes. Any and all payments by the
Borrower to or for the account of any Bank or the Agent hereunder or under any
other Credit Document shall be made free and clear of and without deduction for
any and all present or future taxes, duties, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect to such payments,
excluding, in the case of each Bank and the Agent, taxes imposed on its income,
and franchise taxes imposed on it (all such non-excluded taxes, duties, levies,
imposts, deductions, charges, withholdings, and liabilities with respect to such
payments being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable under
this Agreement or any other Credit Document to any Bank or the Agent, (i) the
sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.11) such Bank or the Agent receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions, (iii) the Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
law, and (iv) the Borrower shall furnish to the Agent written evidence of
payment thereof.

         (b) Other Taxes. In addition, the Borrower agrees to pay any and all
present or future stamp or documentary taxes and any other excise or property
taxes or charges or similar levies which arise from any payment made under this
Agreement or any other Credit Document or from the execution or delivery of, or
otherwise with respect to, this Agreement or any other Credit Document
(hereinafter referred to as "Other Taxes").

         (c) Indemnification. The Borrower agrees to indemnify each Bank and the
Agent for the full amount of Taxes and Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 2.11) paid by such Bank or the Agent (as the
case may be) and any liability (including penalties, interest, and expenses)
arising therefrom or with respect thereto.

         (d) Foreign Bank Withholding Exemption. Each Bank organized under the
laws of a jurisdiction outside the United States, on or prior to the date of its
execution and delivery of this Agreement in the case of each Bank listed on the
signature pages of this Agreement and on or prior to the date on which it
becomes a Bank in the case of each other Bank, and from time to time thereafter
if requested in writing by the Borrower or the Agent (but only so long as such
Bank remains lawfully able to do so), shall provide the Borrower and the Agent
with (i) Internal Revenue Service Form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Bank is entitled to benefits under an income tax treaty to which 


                                      -35-
<PAGE>   41

the United States is a party which reduces the rate of withholding tax on
payments of interest or certifying that the income receivable pursuant to this
Agreement is effectively connected with the conduct of a trade or business in
the United States, (ii) Internal Revenue Service Form W-8 or W-9, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
and (iii) any other form or certificate required by any taxing authority
(including any certificate required by Sections 871(h) and 881(c) of the
Internal Revenue Code), certifying that such Bank is entitled to an exemption
from or a reduced rate of tax on payments pursuant to this Agreement or any of
the other Credit Documents. For any period with respect to which a Bank has
failed to provide the Borrower and the Agent with the appropriate form pursuant
to Section 2.11(d) (unless such failure is due to a change in treaty, law, or
regulation occurring subsequent to the date on which a form originally was
required to be provided), such Bank shall not be entitled to indemnification
under Section 2.11(a) or 2.11(b) with respect to Taxes imposed by the United
States; provided, however, that should a Bank, which is otherwise exempt from or
subject to a reduced rate of withholding tax, become subject to Taxes because of
its failure to deliver a form required hereunder, the Borrower shall take such
steps as such Bank shall reasonably request to assist such Bank to recover such
Taxes.

         (e) Change in Applicable Lending Office. If the Borrower is required to
pay additional amounts to or for the account of any Bank pursuant to this
Section 2.11, then such Bank will agree to use reasonable efforts to change the
jurisdiction of its Applicable Lending Office so as to eliminate or reduce any
such additional payment which may thereafter accrue if such change, in the
judgment of such Bank, is not otherwise disadvantageous to such Bank.

         (f) Evidence of Tax Payments. Within 30 days after the date of any
payment of Taxes, the Borrower shall furnish to the Agent written evidence of
such payment.

         (g) Survival. Without prejudice to the survival of any other agreement
of the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 2.11 shall survive the termination of the Commitments
and the payment in full of the Notes.

         Section 2.12. Sharing of Payments, Etc. If any Bank shall obtain any
payment or collateral (whether voluntary, involuntary, through the exercise of
any right of set-off or otherwise) on account of the Advances made by it in
excess of its Pro Rata Share of payments or collateral on account of the
Advances or Reimbursement Obligations obtained by all the Banks, such Bank shall
notify the Agent and forthwith purchase from the other Banks such participations
in the Advances made by them or Reimbursement Obligations held by them as shall
be necessary to cause such purchasing Bank to share the excess payment or
benefits of such collateral or proceeds ratably in accordance with the
requirements of this Agreement with each of them; provided, however, that if all
or any portion of such excess payment or benefits is thereafter recovered from
such purchasing Bank, such purchase from each Bank shall be rescinded and such
Bank shall repay to the purchasing Bank the purchase price to the extent of such
Bank's ratable share (according to the proportion of (a) the 


                                      -36-
<PAGE>   42

amount of the participation sold by such Bank to the purchasing Bank as a result
of such excess payment to (b) the total amount of such excess payment) of such
recovery, together with an amount equal to such Bank's ratable share (according
to the proportion of (a) the amount of such Bank's required repayment to the
purchasing Bank to (b) the total amount of all such required repayments to the
purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered. The Borrower agrees
that any Bank so purchasing a participation from another Bank pursuant to this
Section 2.12 may, to the fullest extent permitted by law, unless and until
rescinded as provided above, exercise all its rights of payment (including the
right of set-off) with respect to such participation as fully as if such Bank
were the direct creditor of the Borrower in the amount of such participation.

         Section 2.13.     Letters of Credit.

         (a) Issuance. From time to time from the date of this Agreement until
three months before the Maturity Date, at the request of the Borrower, the
Issuing Bank shall, on the terms and conditions hereinafter set forth, issue,
increase, or extend the expiration date of Letters of Credit for the account of
the Borrower on any Business Day. No Letter of Credit will be issued, increased,
or extended:

               (i) if such issuance, increase, or extension would cause the
         Letter of Credit Exposure to exceed the lesser of (1) $10,000,000.00
         and (2) the aggregate Commitments less the aggregate outstanding
         principal amount of all Advances less the aggregate outstanding
         principal amount of all Swing Loans;

              (ii) unless such Letter of Credit has an Expiration Date not later
         than the earlier of (a) one year after the date of issuance thereof and
         (B) the Maturity Date;

              (iii) unless such Letter of Credit is in form and substance
         acceptable to the Issuing Bank in its sole discretion;

              (iv) unless such Letter of Credit is a standby letter of credit
         not supporting the repayment of Debt of any Person;

               (v) unless the Borrower has delivered to the Issuing Bank a
         completed and executed letter of credit application on the Issuing
         Bank's standard form, which application for the initial Issuing Bank is
         in the form of the attached Exhibit G and which successor application
         for the initial Issuing Bank or application for any successor Issuing
         Bank shall contain terms no more restrictive than the terms of this
         Agreement (and in the case of conflict between this Agreement and any
         such application, this Agreement shall control); and



                                      -37-
<PAGE>   43

              (vi) unless such Letter of Credit is governed by the International
         Standby Practices (ISP98), International Chamber of Commerce
         Publication No. 590 or any successor to such publication. If the terms
         of any letter of credit application referred to in the foregoing clause
         (v) conflicts with the terms of this Agreement, the terms of this
         Agreement shall control.

         (b) Participations. Upon the date of the issuance or increase of a
Letter of Credit, the Issuing Bank shall be deemed to have sold to each other
Bank and each other Bank shall have been deemed to have purchased from the
Issuing Bank a participation in the related Reimbursement Obligations equal to
such Bank's Pro Rata Share at such date and such sale and purchase shall
otherwise be in accordance with the terms of this Agreement. The Issuing Bank
shall promptly notify each such participant Bank by telex, telephone, or
telecopy of each Letter of Credit issued or increased and the actual dollar
amount of such Bank's participation in such Letter of Credit.

         (c) Reimbursement. The Borrower hereby agrees to pay on demand to the
Issuing Bank for the benefit of the Banks in respect of each Letter of Credit an
amount equal to any amount paid by the Issuing Bank under or in respect of such
Letter of Credit. In the event the Issuing Bank makes a payment pursuant to a
request for draw presented under a Letter of Credit and such payment is not
promptly reimbursed by the Borrower upon demand, the Issuing Bank shall give
notice of such payment to the Agent and the Banks, and each Bank shall promptly
reimburse the Issuing Bank for such Bank's Pro Rata Share of such payment, and
such reimbursement shall be deemed for all purposes of this Agreement to
constitute a Borrowing comprised of Base Rate Advances to the Borrower from such
Bank. If such reimbursement is not made by any Bank to the Issuing Bank on the
same day on which the Issuing Bank shall have made payment on any such draw,
such Bank shall pay interest thereon to the Issuing Bank at a rate per annum
equal to the Federal Funds Rate. The Borrower hereby unconditionally and
irrevocably authorizes, empowers, and directs the Agent and the Banks to record
and otherwise treat such payment under a Letter of Credit not immediately
reimbursed by the Borrower as a Borrowing comprised of Base Rate Advances to the
Borrower.

         (d) Obligations Unconditional. The obligations of the Borrower under
this Agreement in respect of each Letter of Credit shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, notwithstanding the following circumstances:

               (i) any lack of validity or enforceability of any Letter of
         Credit Documents;

              (ii) any amendment or waiver of or any consent to departure from
         any Letter of Credit Documents;

             (iii) the existence of any claim, set-off, defense or other right
         which the Borrower may have at any time against any beneficiary or
         transferee of such Letter of Credit (or any Persons for whom any such
         beneficiary or any such transferee may be acting), the Issuing Bank,
         any Bank or any other Person, whether in connection with this
         Agreement, the transactions contemplated in this Agreement or in any
         Letter of Credit Documents or any unrelated transaction;



                                      -38-
<PAGE>   44

              (iv) any statement or any other document presented under such
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect to the extent the Issuing Bank would not be
         liable therefor pursuant to the following paragraph (e);

               (v) payment by the Issuing Bank under such Letter of Credit
         against presentation of a draft or certificate which does not comply
         with the terms of such Letter of Credit; or

              (vi) any other circumstance or happening whatsoever, whether or
         not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (d) shall be deemed
to constitute a waiver of any remedies of the Borrower in connection with the
Letters of Credit.

         (e) Liability of Issuing Bank. The Borrower assumes all risks of the
acts or omissions of any beneficiary or transferee of any Letter of Credit with
respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of
its officers or directors shall be liable or responsible for:

               (i) the use which may be made of any Letter of Credit or any acts
         or omissions of any beneficiary or transferee in connection therewith;

              (ii) the validity, sufficiency or genuineness of documents, or of
         any endorsement thereon, even if such documents should prove to be in
         any or all respects invalid, insufficient, fraudulent or forged;

             (iii) payment by the Issuing Bank against presentation of documents
         which do not comply with the terms of a Letter of Credit, including
         failure of any documents to bear any reference or adequate reference to
         the relevant Letter of Credit; or

              (iv) any other circumstances whatsoever in making or failing to
         make payment under any Letter of Credit (including the Issuing Bank's
         own negligence),

except that the Borrower shall have a claim against the Issuing Bank, and the
Issuing Bank shall be liable to, and shall promptly pay to, the Borrower, to the
extent of any direct, as opposed to consequential, damages suffered by the
Borrower which the Borrower proves were caused by (a) the Issuing Bank's willful
misconduct or gross negligence in determining whether documents presented under
a Letter of Credit comply with the terms of such Letter of Credit or (B) the
Issuing Bank's 


                                      -39-
<PAGE>   45

willful failure to make lawful payment under any Letter of Credit after the
presentation to it of a draft and certificate strictly complying with the terms
and conditions of such Letter of Credit.

In furtherance and not in limitation of the foregoing, the Issuing Bank may
accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

any law or any contractual restriction binding on or affecting such Credit
Party, the contravention of which would reasonably be expected to cause a
Material Adverse Change and (d) will not result in or require the creation or

Borrowing, such Borrowing and the use of the proceeds of such Borrowing will be
within the Borrower's corporate powers, will have been duly authorized by all
necessary corporate action, (a) will not contravene (i) the Borrower's
certificate of incorporation or by-laws or (ii) any law or any contractual

necessary in order to obtain and maintain perfection of Liens, (b) Filings

         Section 4.04. Enforceable Obligations. Each Credit Document has been
duly executed and delivered by each Credit Party which is a party to it. Each
Credit Document is the legal, valid, and binding obligation of each Credit Party
which is a party to it, enforceable against such Credit Party in accordance with
its terms, except as such enforceability may be limited by any applicable
bankruptcy, insolvency, reorganization, moratorium, or similar law affecting
creditors' rights generally and by general principles of equity (whether
considered in proceeding at law or in equity).

         Section 4.05. Financial Statements. (a) The audited balance sheet of
the Borrower and its Subsidiaries as at March 31, 1998, and the related

absence of footnotes, the financial condition of the Borrower and its
Subsidiaries as at such dates and the results of the operations of the Borrower
and its Subsidiaries for the periods ended on such dates, and such balance

such date), and none of the Property owned or leased by any Credit Party is
subject to any Lien except Permitted Liens.

         Section 4.07. True and Complete Disclosure. No representation,
warranty, or other statement made by any Credit Party (or on behalf of any
Credit Party) in this Agreement or any other Credit Document contains any untrue
statement of a material fact or omits to state any material fact necessary to
make the statements contained therein not misleading in light of the
circumstances in which they were made as of the date of this Agreement the
effect of which would reasonably be expected to cause a Material Adverse Change.
There is no fact known to any Responsible Officer of the Borrower on the date of
this Agreement and on the Effective Date that has not been disclosed to the
Agent which would reasonably be expected to cause a Material Adverse Change. All
projections, estimates, and pro forma financial information furnished by the
Borrower or on behalf 


                                      -45-

of the Borrower were prepared on the basis of assumptions, data, information,
tests, or conditions believed to be reasonable at the time such projections,
estimates, and pro forma financial information were furnished.

         Section 4.08. Litigation. Except as otherwise disclosed to the Banks in
writing, there is no pending or, to the best knowledge of the Borrower,
threatened action or proceeding affecting the Borrower or any of its
Subsidiaries before any court, Governmental Agency or arbitrator, which would
reasonably be expected to cause a Material Adverse Change or which purports to
affect the legality, validity, binding effect or enforceability of this
Agreement, any Note, the Swing Note, or any other Credit Document or the
consummation of any of the transactions contemplated hereby or thereby.

         Section 4.09. Use of Proceeds. The proceeds of Advances and Swing Loans
may be used by the Borrower only for working capital, for Capital Expenditures,
and for general corporate purposes, including for acquisitions. The Borrower is
not engaged in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation U). No proceeds of any
Advance or any Swing Loan will be used to purchase or carry any margin stock in
violation of Regulation T, U or X.

         Section 4.10. Investment Company Act. Neither the Borrower nor any of
its Subsidiaries is an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

Utility Holding Company Act of 1935, as amended.

         Section 4.12. Taxes. Each of the Borrower and each of its Subsidiaries
has filed or caused to be filed all tax returns required by law to be filed and
has paid or caused to be paid all taxes, assessments and other governmental
charges levied upon or in respect of any of its Properties, other than taxes the
validity or amount of which are being contested in good faith by the Borrower or
such Subsidiary by appropriate proceedings and for which the Borrower or such
Subsidiary shall have set aside on its books adequate reserves in accordance
with GAAP. The charges, accruals and reserves on the books of the Borrower and
its Subsidiaries in respect of taxes for all fiscal periods are adequate, and
there is not unpaid assessment for additional taxes for any fiscal period or any
basis therefor.

         Section 4.13. Pension Plans. No Termination Event has occurred with
respect to any Plan, and each Plan has complied with and been administered in
all material respects in accordance with applicable provisions of ERISA and the
Code. No "accumulated funding deficiency" (as defined in 


                                      -46-
<PAGE>   52

Section 302 of ERISA) has occurred and there has been no excise tax imposed
under Section 4971 of the Code. To the knowledge of any Responsible Officer of
the Borrower, no Reportable Event has occurred with respect to any Multiemployer
Plan, and each Multiemployer Plan has complied with and been administered in all
material respects with applicable provisions of ERISA and the Code. The present
value of all benefits vested under each Plan (based on the assumptions used to
fund such Plan) did not, as of the last annual valuation date applicable
thereto, exceed the value of the assets of such Plan allocable to such vested
benefits in any amount that would reasonably be expected to cause a Material
Adverse Change. Neither the Borrower nor any member of the Controlled Group has
had a complete or partial withdrawal from any Multiemployer Plan for which there
is any material withdrawal liability. As of the most recent valuation date
applicable thereto, neither the Borrower nor any member of the Controlled Group
has received notice that any Multiemployer Plan is insolvent or in
reorganization. Based upon GAAP existing as of the date of this Agreement and
current factual circumstances, the Borrower has no reason to believe that the
annual cost during the term of this Agreement to the Borrower or any of its
Subsidiaries for post-retirement benefits to be provided to the current and
former employees of the Borrower or any of its Subsidiaries under welfare
benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate,
reasonably be expected to cause a Material Adverse Change.

         Section 4.14. Insurance. The Borrower and each of its Subsidiaries
carry insurance with reputable insurers in respect of such of their respective
Properties, in such amounts and against such risks as is customarily maintained
by other Persons of similar size engaged in similar businesses or, self-insure
to the extent that is customary for Persons of similar size engaged in similar
businesses.

         Section 4.15.     No Burdensome Restrictions; No Defaults.

         (a) No Credit Party is a party to any indenture, loan or credit
agreement or any lease or other agreement or instrument or subject to any
charter or corporate restriction or provision of applicable Legal Requirement
which would reasonably be expected to cause a Material Adverse Change. No Credit
Party is in default under or with respect to any contract, agreement, lease or
other instrument to which such Credit Party is a party and which would
reasonably be expected to cause a Material Adverse Change. To the knowledge of
each Responsible Officer of the Borrower, no Credit Party has received any
notice of default under any contract, agreement, lease or other instrument to
which such Credit Party is a party which is continuing or which, if not cured,
would reasonably be expected to cause a Material Adverse Change.

         (b)      No Default has occurred and is continuing.

         Section 4.16.     Environmental Condition.

         (a) The Credit Parties, taken as a whole, (i) have obtained all
Environmental Permits necessary for the ownership and operation of their
respective material Properties and the conduct of 


                                      -47-
<PAGE>   53

their respective businesses; (ii) have been and are in compliance with all terms
and conditions of such Environmental Permits and with all other material
requirements of applicable Environmental Laws of which the failure to comply
would reasonably be expected to cause a Material Adverse Change; (iii) have not
received notice of any violation or alleged violation of any Environmental Law
or Environmental Permit the violation of which would reasonably be expected to
cause a Material Adverse Change; and (iv) are not subject to any Environmental
Claim known to any Credit Party, which Environmental Claim would reasonably be
expected to cause a Material Adverse Change.

         (b) To the knowledge of any Responsible Officer of the Borrower, none
of the present or previously owned or operated Property of the Borrower or of
any of its present or former Subsidiaries, wherever located, (i) has been placed
on or, to any Credit Party's knowledge, proposed to be placed on the National
Priorities List, the Comprehensive Environmental Response Compensation Liability
Information System list, or their state or local analogs, or have been otherwise
designated or listed as a potential site for removal, remediation, cleanup,
closure, restoration, reclamation, or other response activity under any
Environmental Laws; (ii) is subject to a Lien, arising under or in connection
with any Environmental Laws, that attaches to any revenues or to any Property
owned or operated by the Borrower or any of its Subsidiaries, wherever located,
which Lien would reasonably be expected to cause a Material Adverse Change; or
(iii) to any Credit Party's knowledge, has been the site of any Release of
Hazardous Substances or Hazardous Wastes from present or past operations which
has caused at the site or at any third-party site any condition that has
resulted in or would reasonably be expected to result in the need for Response
that would cause a Material Adverse Change.

         (c) Without limiting the foregoing, the present and, to the best
knowledge of any Responsible Officer of the Borrower, future liability, if any,
of the Credit Parties, taken as a whole, which would reasonably be expected to
arise in connection with requirements under Environmental Laws will not result
in a Material Adverse Change.

         Section 4.17. Permits, Licenses, etc. The Credit Parties possess all
permits, licenses, patents, patent rights or licenses, trademarks, trademark
rights, trade names rights and copyrights which are material to the conduct of
its business. The Credit Parties manage and operate their businesses in
accordance with all applicable Legal Requirements which the failure to so manage
or operate would reasonably be expected to cause a Material Adverse Change.

         Section 4.18. Security Interests. On the Effective Date, all
governmental actions and all other filings, recordings, registrations, third
party consents, and other actions which are necessary to create and perfect the
Liens provided for in the Security Documents will have been made, obtained, and
taken in all relevant jurisdictions, or satisfactory arrangements will have been
made for all governmental actions and all other filings, recordings,
registrations, third party consents, and other actions which are necessary to
create and perfect the Liens provided for in the Security Documents to be made,
obtained, or taken in all relevant jurisdictions.

         Section 4.19. Compliance with Laws, Material Agreements. No Credit
Party is in violation of any Legal Requirement the failure to comply with which
would reasonably be expected to cause a Material Adverse Change. No Credit Party
is in violation of any provision of any Material Agreement to which it is a
party, and the execution and delivery of this Agreement and the Credit Documents
and the consummation of the transactions contemplated thereunder shall not
result in any breach of any provisions of, or constitute a default under, any
Material Agreement, except any violation, breach, or default which could not
reasonably be expected to result in a Material Adverse Change.

         Section 4.20. Year 2000. The Borrower has (a) completed a review and
assessment of all areas within its and each of its Subsidiaries' and the
Acquired Business' and its Subsidiaries' business and operations (including
those affected by suppliers, vendors, and customers) that could be adversely
affected by the Year 2000 Problem (as defined in Section 3.01(l)), (b) developed
a plan and timeline for addressing on a timely basis, but in any event before
July 1, 1999, the Year 2000 Problem, and (c) to date, implemented that plan
substantially in accordance with that timetable. Based on the foregoing, the
Borrower believes that all computer applications (including those of its
suppliers, vendors, and customers) that are material to its or any of its
Subsidiaries' or the Acquired Business' or any of its Subsidiaries' business and
operations are reasonably expected on a timely basis, but in any event before
July 1, 1999, to be Year 2000 Compliant (as defined in Section 3.01(l)), except
to the extent that a failure to do so could not reasonably be expected to result
in a Material Adverse Change.

         Section 4.21. Regulatory Matters. Without limiting the representations
and warranties included in Section 4.19, the Borrower represents and warrants
the following, to the extent that the inaccuracy of any of the following would
reasonably be expected to cause a Material Adverse Change:

controlled substances and regulating promotional activities performed on behalf
of sponsors of medical products.

                              AFFIRMATIVE COVENANTS

         So long as any Note, the Swing Note, or any amount under any Credit
Document shall remain unpaid, any Letter of Credit shall remain outstanding, or
any Bank shall have any Commitment hereunder, the Borrower agrees, unless the
Majority Banks shall otherwise consent in writing, to comply with the following
covenants.

         Section 5.01. Compliance with Laws, Material Agreements, Etc. The
Borrower will comply, and cause each of its Subsidiaries to comply, with all
Legal Requirements of which the failure to comply would reasonably be expected
to cause a Material Adverse Change. Without limiting the generality and coverage
of the foregoing, the Borrower shall comply, and shall cause each of its
Subsidiaries to comply, in all material respects, with all Material Agreements,
Environmental Laws, and, in all material respects, all laws, regulations, or
directives with respect to equal employment opportunity and employee safety in
all jurisdictions in which the Borrower, or any of its Subsidiaries do business;
provided, however, that this Section 5.01 shall not prevent the Borrower, or any
of its Subsidiaries from, in good faith and with reasonable diligence,
contesting the validity or application of any such laws or regulations by
appropriate legal proceedings.

         Section 5.02. Maintenance of Insurance. The Borrower will maintain, and
cause each of its Subsidiaries to maintain, insurance with responsible and
reputable insurance companies or associations in such amounts and covering such
risks as are usually carried by companies engaged in similar businesses and
owning similar properties in the same general areas in which the Borrower or
such Subsidiary operates, provided that the Borrower or such Subsidiary may
self-insure to the extent and in the manner normal for similarly situated
companies of like size, type and financial condition that are part of a group of
companies under common control.

         Section 5.03. Preservation of Corporate Existence, Etc. The Borrower
will preserve and maintain, and cause each of its Subsidiaries to preserve and
maintain, its corporate existence, rights, franchises and privileges in the
jurisdiction of its incorporation, and qualify and remain qualified, and cause

in each jurisdiction in which qualification is necessary or desirable in view of
its business and operations or the ownership of its properties, and, in each
case, where failure to qualify or preserve and maintain its rights and
franchises would reasonably be expected to cause a Material Adverse Change;
provided, however, that nothing contained in this Section 5.03 shall prevent any
transaction permitted by Section 6.05.

         Section 5.04. Payment of Taxes, Etc. The Borrower will pay and
discharge, and cause each of its Subsidiaries to pay and discharge, before the
same shall become delinquent and which the failure to timely pay or discharge
would reasonably be expected to cause a Material Adverse Change, 


                                      -51-
<PAGE>   57

(a) all taxes, assessments and governmental charges or levies imposed upon it or
upon its income or profits or Property that are material in amount, prior to the
date on which penalties attach thereto and (b) all lawful claims that are
material in amount which, if unpaid, might by law become a Lien upon its
Property; provided, however, that neither the Borrower nor any such Subsidiary
shall be required to pay or discharge any such tax, assessment, charge, levy, or
claim which is being contested in good faith and by appropriate proceedings, and
with respect to which reserves in conformity with GAAP have been provided.

         Section 5.05.     Visitation Rights; Environmental Inspections.

         (a) At any reasonable time and from time to time and so long as any
visit or inspection will not interfere unreasonably with any Credit Party's
operations, upon reasonable notice, the Borrower will, and will cause its
Subsidiaries to, permit the Agent and any Bank or any of its agents or
representatives thereof, to examine and make copies of and abstracts from the
records and books of account of, and visit and inspect at its reasonable
discretion the properties of, any such Credit Party, to discuss the affairs,
finances, and accounts of any such Credit Party with any of its respective
officers or directors.

         (b) If any event or series of events causes the Credit Parties to spend
more than $1,000,000.00 in the aggregate in connection with corrective action,
including, without limitation, any necessary cleanup, removal, or remediation of
Hazardous Substances or Hazardous Waste, for failure to comply with any
Environmental Law (other than Environmental Laws described in clause (d) of the
definition of Environmental Laws), then, at the Majority Banks' written request,
the Borrower shall at its expense (such expense being reasonably acceptable to
the Borrower) contract for the services of Persons to enter upon the Credit
Parties' properties to perform environmental site assessments for the purpose of
determining whether there exists any Environmental condition that would result
in a similar liability, cost, or expense to the Borrower or any of its
Subsidiaries under any of the conditions necessitating the corrective measures
described above. The scope of any such environmental assessment shall be subject
to the Borrower's consent, which consent shall not be unreasonably withheld.
Such site assessments shall be performable only at selected properties for which
the requesting Banks shall have demonstrable evidence of being similarly
affected as the affected properties, and which have the same or similar physical
or operational characteristics as the affected properties such that the selected
properties would be reasonably expected to have the same or similar conditions
as those causing the incurrence of the costs referred to above. Such
environmental assessments shall remain confidential and shall not be disclosed
to any third party except as permitted by Section 9.08.

         (a) merge or consolidate with or into any other Person, except that (i)
the Borrower may merge with any of its wholly-owned Subsidiaries, (ii) any of
the Borrower's wholly-owned Subsidiaries may merge with another of the
Borrower's wholly-owned Subsidiaries, and (iii) a merger used to consummate a
Permitted Acquisition may occur, provided that immediately after giving effect
to any such proposed transaction no Default would exist and, in the case of any
such merger to which a Credit Party is a party, such Credit Party is the
surviving corporation or such surviving corporation has assumed such Credit
Party' obligations under the Credit Documents in a manner reasonably acceptable
to the Agent.

         (b) sell, lease, transfer, or otherwise dispose of any assets other
than (i) sales of inventory in the ordinary course of business, (ii)
dispositions of assets outside the ordinary course of business to any Person
other than a Credit Party for an aggregate consideration (whether in cash,
Property, assumption of Debt, or issuance of equity) of $5,000,000.00 or less
for each such sale or related series of sales and for which at least 70% of the
purchase price received by the Credit Parties is in Dollars and in cash, (iii)
dispositions of assets outside the ordinary course of business not otherwise
permitted by (ii) above in an aggregate amount for any fiscal year not to exceed

         Section 6.06. Permitted Investments. The Borrower will not, and will
not permit any of its Subsidiaries to, make or permit to exist any loans,
advances, or capital contributions to, or make any investment in, or purchase or
commit to purchase any stock or other securities or evidences of indebtedness of
or interests in any Person, except Permitted Investments.

         Section 6.07. Affiliate Transactions. Except as expressly permitted
elsewhere in this Agreement, the Borrower will not, and will not permit any of
its Subsidiaries to, make, directly or indirectly: (a) any investment in any
Affiliate (other than a wholly-owned Subsidiary of the Borrower) (a "Restricted
Affiliate"); (b) any transfer, sale, lease, assignment or other disposal of any
assets to any Restricted Affiliate or any purchase or acquisition of assets from
any Restricted Affiliate; or (c) any arrangement or other transaction directly
or indirectly with or for the benefit of any Restricted Affiliate (including
without limitation, guaranties and assumptions of obligations of an Affiliate);
provided that the Credit Parties may enter into any arrangement or other
transaction with any Restricted Affiliate if the monetary or business
consideration arising therefrom would be substantially as advantageous to the
Credit Parties as the monetary or business consideration which it would obtain
in a comparable arm's length transaction with a Person not a Restricted
Affiliate.

         Section 6.08. Compliance with ERISA. The Borrower will not, and will
not permit any of its Subsidiaries to, (a) terminate any Plan so as to result in
any material (in the opinion of the Majority Banks) liability of the Borrower or

other event or condition, which presents a material (in the opinion of the
Majority Banks) risk of such a termination by the PBGC of any Plan under Section
4042 of ERISA.

         Section 6.09. Maintenance of Ownership of Subsidiaries. Except for
issuances, sales or other dispositions to the Borrower or a wholly-owned
Subsidiary of the Borrower, the Borrower will not, and will not permit any of
its Subsidiaries to, sell or otherwise dispose of any shares of capital stock of
any of the Borrower's Subsidiaries or permit any Subsidiary to issue, sell, or
otherwise dispose of any shares of its capital stock or the capital stock of any
of the Borrower's Subsidiaries.

         Section 6.10. Fixed Coverage Ratio. The Borrower will not permit the
ratio of (a) EBITDA plus Lease Expense to (b) its Fixed Charges as of the end of
any fiscal quarter for the four fiscal quarters then ended to be less than 3.25
to 1.0. For the fiscal quarters ending June 30, 1999, September 30, 1999, and
December 31, 1999 the foregoing ratio shall be calculated for the one, two, and
three fiscal quarter period, respectively, ending on such dates.

         Section 6.11. Leverage Ratio. The Borrower will not permit its Leverage

each fiscal quarter beginning with the fiscal quarter beginning July 1, 1999, if
Net Income is positive for such quarter, but without reductions for fiscal
quarters during which Net Income is negative plus (C) 85% of the Net Cash
Proceeds from the sale of capital stock, warrants, or options to purchase
capital stock or other equity interests, and other equity interests of Borrower
or any Credit Party since the Effective Date plus (D) 85% of any increase in Net
Worth from the conversion of any Debt to equity, without duplication of the

any other transaction the effect of which is to increase the Borrower's Net
Worth.

         Section 6.13. Capital Expenditures. The Borrower shall not, and shall
not permit any of its Subsidiaries to, make any Capital Expenditure (other than
Capital Expenditures that are part of a Permitted Acquisition) which when

Note, the Swing Note or any Reimbursement Obligation when due or (ii) pay any
interest on any Note or the Swing Note, or any fee or other amount payable

         (b) Representation and Warranties. Any representation or warranty made
or deemed to be made (i) by the Borrower in this Agreement or in any other
Credit Document, (ii) by the Borrower (or any of its officers) in connection
with this Agreement or any other Credit Document, or (iii) by any Subsidiary in
any Credit Document shall prove to have been incorrect in any material respect
when made or deemed to be made;

         (c) Covenant Breaches. (i) The Borrower shall (a) fail to perform or
observe any covenant contained in Article VI of this Agreement or (B) fail to
perform or observe any other term or covenant set forth in this Agreement or in
any other Credit Document which is not covered by clause (i)(a) above or any

10 Business Days after the earlier of (1) written notice of such default shall
have been given to the Borrower by the Agent or any Bank, or (2) a Responsible
Officer of the Borrower's actual knowledge of such default or (ii) any Credit
Party shall fail to perform or observe any covenant made by it in any Credit
Document to which it is a party and such failure shall remain unremedied for 10
Business Days after the earlier of (a) written notice of such default shall have
been given to the Borrower by the Agent or any Bank, or (B) a Responsible
Officer of the Borrower's actual knowledge of such default;

         (d) Cross-Defaults. (i) The Borrower or any Credit Party shall fail to
pay any principal of or premium or interest on its Debt which is outstanding in
a principal amount of at least $1,000,000.00 individually or when aggregated
with all such Debt of the Borrower or the Credit Parties so in default (but
excluding Debt evidenced by the Notes and the Swing Note) when the same becomes
due and payable (whether by scheduled maturity, required prepayment,
acceleration, demand or otherwise), and such failure shall continue after the
applicable grace period, if any, specified in the agreement or instrument
relating to such Debt; (ii) any other event shall occur or 




                                      -59-
<PAGE>   65

condition shall exist under any agreement or instrument relating to Debt which
is outstanding in a principal amount of at least $1,000,000.00 individually or
when aggregated with all such Debt of the Credit Parties so in default, and
shall continue after the applicable grace period, if any, specified in such
agreement or instrument, if the effect of such event or condition is to
accelerate, or to permit the acceleration of, the maturity of such Debt prior to
the stated maturity thereof; or (iii) any such Debt shall be declared to be due
and payable, or required to be prepaid (other than by a regularly scheduled
required prepayment or prepayments contractually required from proceeds received
upon the sale of any Property);

         (e) Insolvency. The Borrower or any of its Subsidiaries shall generally
not pay its debts as such debts become due, or shall admit in writing its
inability to pay its debts generally, or shall make a general assignment for the
benefit of creditors; or any proceeding shall be instituted by or against the
Borrower or any of its Subsidiaries seeking to adjudicate it bankrupt or
insolvent, or seeking liquidation, winding up, reorganization, arrangement,
adjustment, protection, relief, or composition of it or its debts under any law
relating to bankruptcy, insolvency or reorganization or relief of debtors, or
seeking the entry of an order for relief or the appointment of a receiver,
trustee or other similar official for it or for any substantial part of its
property and, in the case of any such proceeding instituted against the Borrower
or any such Subsidiary, either such proceeding shall remain undismissed for a
period of 30 days or any of the actions sought in such proceeding shall occur;
or the Borrower or any of its Subsidiaries shall take any corporate action to
authorize any of the actions set forth above in this paragraph (e);

         (f) Judgments. Any judgment or order for the payment of money in excess
of $1,000,000.00 (reduced for purposes of this paragraph for the amount in
respect of such judgment or order that a reputable insurer has acknowledged as
being payable under any valid and enforceable insurance policy) shall be
rendered against the Borrower or any of its Subsidiaries and either (i)
enforcement proceedings shall have been commenced by any creditor upon such
judgment or order or (ii) there shall be any period of 30 consecutive days
during which a stay of enforcement of such judgment or order, by reason of a
pending appeal or otherwise, shall not be in effect;

         (g) Termination Events. Any Termination Event with respect to a Plan
shall have occurred, and, 30 days after notice thereof shall have been given to
the Borrower by the Agent, (i) such Termination Event shall have created and
caused to be continuing a material risk of Plan termination or liability for
withdrawal from the Plan as a substantive employer and (ii) the then present
value of such Plan's vested benefits exceeds the then current value of assets
accumulated in such Plan by more than the amount of $1,000,000.00 (or in the
case of a Termination Event involving the withdrawal of a "substantial employer"
(as defined in Section 4001(a)(2) of ERISA), the withdrawing employer's
proportionate share of such excess shall exceed such amount);

         (h) Plan Withdrawals. The Borrower or any member of the Controlled
Group as employer under a Multiemployer Plan shall have made a complete or
partial withdrawal from such 


                                      -60-
<PAGE>   66

Multiemployer Plan and the plan sponsor of such Multiemployer Plan shall have
notified such withdrawing employer that such employer has incurred a withdrawal
liability in an annual amount exceeding $1,000,000.00;

         (i) Guaranties. Any Guaranty shall at any time and for any reason other
than according to its terms cease to be in full force and effect or shall be
contested by any party thereto; or any Guarantor shall deny it has any liability
or obligation under its Guaranty;

         (j) Security Documents. Any Security Document shall at any time and for
any reason cease to create the Lien on the property purported to be subject to
such agreement in accordance with the terms of such agreement and, if such
deficiency can be cured, such Credit Party has failed to cure such deficiency
after demand by the Agent, or cease to be in full force and effect, or shall be
contested by any Credit Party which is a party thereto; or

         (k) Change in Control. A Change in Control shall occur.

         Section 7.02. Optional Acceleration of Maturity. If any Event of
Default (other than an Event of Default pursuant to paragraph (e) of Section
7.01) shall have occurred and be continuing, then, and in any such event,

         (a) the Agent (i) shall at the request, or may with the consent, of the
Majority Banks, by notice to the Borrower, declare the obligation of each Bank
to make Advances and the obligation of the Issuing Bank to issue, increase, or
extend Letters of Credit to be terminated, whereupon the same shall forthwith
terminate, and (ii) shall at the request, or may with the consent, of the
Majority Banks, by notice to the Borrower, declare the Notes and the Swing Note,
all interest thereon, the Reimbursement Obligations, and all other amounts
payable under this Agreement to be forthwith due and payable, whereupon the
Notes and the Swing Note, all such interest, all such Reimbursement Obligations
and all such amounts shall become and be forthwith due and payable in full,
without presentment, demand, protest or further notice of any kind (including,
without limitation, any notice of intent to accelerate or notice of
acceleration), all of which are hereby expressly waived by the Borrower;

         (b) the Borrower shall, on demand of the Agent at the request or with
the consent of the Majority Banks, deposit with the Agent into the Cash
Collateral Account an amount of cash equal to the Letter of Credit Exposure as
security for the Obligations to the extent the Reimbursement Obligations are not
otherwise paid at such time; and

         (c) the Agent shall at the request of, or may with the consent of, the
Majority Banks proceed to enforce its rights and remedies under the Security
Documents, the Guaranties, or any other Credit Document for the ratable benefit
of the Banks by appropriate proceedings.



                                      -61-
<PAGE>   67

Section 7.03. Automatic Acceleration of Maturity. If any Event of Default
pursuant to paragraph (e) of Section 7.01 shall occur,

         (a) the obligation of each Bank to make Advances and the obligation of
the Issuing Bank to issue, increase, or extend Letters of Credit shall
immediately and automatically be terminated and the Notes, the Swing Note, all
interest on the Notes and the Swing Note, all Reimbursement Obligations, and all
other amounts payable under this Agreement shall immediately and automatically
become and be due and payable in full, without presentment, demand, protest or
any notice of any kind (including, without limitation, any notice of intent to
accelerate or notice of acceleration), all of which are hereby expressly waived
by the Borrower;

         (b) the Borrower shall deposit with the Agent into the Cash Collateral
Account an amount of cash equal to the outstanding Letter of Credit Exposure as
security for the Obligations to the extent the Reimbursement Obligations are not
otherwise paid at such time; and

         (c) the Agent shall at the request of, or may with the consent of, the
Majority Banks proceed to enforce its rights and remedies under the Security
Documents, the Guaranties, or any other Credit Document for the ratable benefit
of the Banks by appropriate proceedings.

         Section 7.04.     Cash Collateral Account.

         (a) Pledge. The Borrower hereby pledges, and grants to the Agent for
the benefit of the Banks, a security interest in all funds held in the Cash
Collateral Account from time to time and all proceeds thereof, as security for
the payment of the Obligations, including all Reimbursement Obligations owing to
the Issuing Bank or any other Bank due and to become due from the Borrower to
the Issuing Bank or any other Bank under this Agreement in connection with the
Letters of Credit. Nothing in this Section 7.04, however, shall either obligate
the Agent to require any funds to be deposited in the Cash Collateral Account or
limit the right of the Agent, which it may exercise at any time and from time to
time, to release to the Borrower any funds held in the Cash Collateral Account
pursuant to the other provisions of this Section 7.04.

         (b) Application against Reimbursement Obligations; Release of Funds.
The Agent may, at any time or from time to time apply funds then held in the
Cash Collateral Account to the payment of any Reimbursement Obligations owing to
the Issuing Bank, in such order as the Agent may elect, as shall have become or
shall become due and payable by the Borrower to the Issuing Bank under this
Agreement in connection with the Letters of Credit. So long as no Event of
Default referred to in paragraph (a) or (e) of Section 7.01 shall have occurred
and be continuing, the Agent will release to the Borrower at the Borrower's
written request funds held in the Cash Collateral Account in an amount up to but
not exceeding the excess, if any (immediately prior to the release of any such
funds), of (i) the total amount of funds held in the Cash Collateral Account
over (ii) the Letter of Credit Exposure.



                                      -62-
<PAGE>   68

         (c) Duty of Care. The Agent shall exercise reasonable care in the
custody and preservation of any funds held in the Cash Collateral Account and
shall be deemed to have exercised such care if such funds are accorded treatment
substantially equivalent to that which the Agent accords its own property, it
being understood that the Agent shall not have any responsibility for taking any
necessary steps to preserve rights against any parties with respect to any such
funds.

         Section 7.05. Non-exclusivity of Remedies. No remedy conferred upon the
Agent is intended to be exclusive of any other remedy, and each remedy shall be
cumulative of all other remedies existing by contract, at law, in equity, by
statute or otherwise.

         Section 7.06. Right of Set-off. Upon the occurrence and during the
continuance of any Event of Default, each Bank (and each of its affiliates) is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final, but excluding deposits that such Bank
knows or, with reasonable inquiry should know, are held by the Borrower in a
fiduciary capacity for the benefit of others) at any time held and other
indebtedness at any time owing by such Bank (or any of its affiliates) to or for
the credit or the account of the Borrower against any and all of the obligations
of the Borrower now or hereafter existing under this Agreement and the Note held
by such Bank, irrespective of whether such Bank shall have made any demand under
this Agreement or such Note and although such obligations may be unmatured. Each
Bank agrees promptly to notify the Borrower after any such set-off and
application made by such Bank; provided, however, that the failure to give such
notice shall not affect the validity of such set-off and application. The rights
of each Bank under this Section are in addition to other rights and remedies
(including, without limitation, other rights of set-off) that such Bank may
have.

         Section 7.07. Application of Payments. Prior to an Event of Default,
all payments made hereunder shall be applied as directed by the Borrower, but
such payments are subject to the terms of this Agreement, including the
application of prepayments according to Section 2.07. During the existence of an
Event of Default, all payments and collections shall be applied to the Credit
Obligations in accordance with Section 2.10 first to any reimbursements and
indemnifications due to the Banks, then ratably to any accrued and unpaid
interest and fees due to the Banks, then to the outstanding principal balance of
the Swing Loans, then ratably to the outstanding principal balance of the
Advances and the Reimbursement Obligations.


                                  ARTICLE VIII

                         THE AGENT AND THE ISSUING BANK



                                      -63-
<PAGE>   69

         Section 8.01. Appointment, Powers, and Immunities. Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its agent under this
Agreement and the other Credit Documents with such powers and discretion as are
specifically delegated to the Agent by the terms of this Agreement and the other
Credit Documents, together with such other powers as are reasonably incidental
thereto. The Agent (which term as used in this sentence and in Section 8.05 and
the first sentence of Section 8.06 shall include its affiliates and its own and
its affiliates' officers, directors, employees, and agents): (a) shall not have
any duties or responsibilities except those expressly set forth in this
Agreement and shall not be a trustee or fiduciary for any Bank; (b) shall not be
responsible to the Banks for any recital, statement, representation, or warranty
(whether written or oral) made in or in connection with any Credit Document or
any certificate or other document referred to or provided for in, or received by
any of them under, any Credit Document, or for the value, validity,
effectiveness, genuineness, enforceability, or sufficiency of any Credit
Document, or any other document referred to or provided for therein or for any
failure by any Credit Party or any other Person to perform any of its
obligations thereunder; (c) shall not be responsible for or have any duty to
ascertain, inquire into, or verify the performance or observance of any
covenants or agreements by any Credit Party or the satisfaction of any condition
or to inspect the property (including the books and records) of any Credit Party
or any of its Subsidiaries or affiliates; (d) shall not be required to initiate
or conduct any litigation or collection proceedings under any Credit Document;
and (e) shall not be responsible for any action taken or omitted to be taken by
it under or in connection with any Credit Document, except for its own gross
negligence or willful misconduct. The Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.

         Section 8.02. Reliance by Agent. The Agent shall be entitled to rely
upon any certification, notice, instrument, writing, or other communication
(including, without limitation, any thereof by telephone or telecopy) reasonably
believed by it to be genuine and correct and to have been signed, sent or made
by or on behalf of the proper Person or Persons, and upon advice and statements
of legal counsel (including counsel for any Credit Party), independent
accountants, and other experts selected by the Agent. The Agent may deem and
treat the payee of any Note as the holder thereof for all purposes of this
Agreement unless and until the Agent receives and accepts an Assignment and
Acceptance executed in accordance with Section 9.06. As to any matters not
expressly provided for by this Agreement, the Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Majority Banks, and such instructions
shall be binding on all of the Banks; provided, however, that the Agent shall
not be required to take any action that exposes the Agent to personal liability
or that is contrary to any Credit Document or applicable law or unless it shall
first be indemnified to its satisfaction by the Banks against any and all
liability and expense which may be incurred by it by reason of taking any such
action.



                                      -64-
<PAGE>   70

         Section 8.03. Defaults. The Agent shall not be deemed to have knowledge
or notice of the occurrence of a Default or Event of Default unless the Agent
has received written notice from a Bank or the Borrower specifying such Default
or Event of Default and stating that such notice is a "Notice of Default". In
the event that the Agent receives such a notice of the occurrence of a Default
or Event of Default, the Agent shall give prompt notice thereof to the Banks.
The Agent shall (subject to Section 8.02) take such action with respect to such
Default or Event of Default as shall reasonably be directed by the Majority
Banks, provided that, unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Banks.

         Section 8.04. Rights as Bank. With respect to its Commitment and the
Advances made by it, NationsBank (and any successor acting as Agent) in its
capacity as a Bank hereunder shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not acting as the
Agent, and the term "Bank" or "Banks" shall, unless the context otherwise
indicates, include the Agent in its individual capacity. NationsBank (and any
successor acting as Agent) and its affiliates may (without having to account
therefor to any Bank) accept deposits from, lend money to, make investments in,
provide services to, and generally engage in any kind of lending, trust, or
other business with any Credit Party or any of its Subsidiaries or affiliates as
if it were not acting as Agent, and NationsBank (and any successor acting as
Agent) and its affiliates may accept fees and other consideration from any
Credit Party or any of its Subsidiaries or affiliates for services in connection
with this Agreement or otherwise without having to account for the same to the
Banks.

         Section 8.05. Indemnification. The Banks agree to indemnify the Agent
(to the extent not reimbursed under Section 9.07, but without limiting the
obligations of the Borrower under such Section) ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including
attorneys' fees), or disbursements of any kind and nature whatsoever that may be
imposed on, incurred by or asserted against the Agent (including by any Bank) in
any way relating to or arising out of any Credit Document or the transactions
contemplated thereby or any action taken or omitted by the Agent under any
Credit Document (including any of the foregoing arising from the negligence of
the Agent); provided that no Bank shall be liable for any of the foregoing to
the extent they arise from the gross negligence or willful misconduct of the
Person to be indemnified. Without limitation of the foregoing, each Bank agrees
to reimburse the Agent promptly upon demand for its ratable share of any costs
or expenses payable by the Borrower under Section 9.04, to the extent that the
Agent is not promptly reimbursed for such costs and expenses by the Borrower;
provided, however that upon recovery of any or all of such costs and expenses by
the Agent from the Borrower, the Agent shall remit to each Bank its ratable
share of such amounts so recovered. The agreements contained in this Section
shall survive payment in full of the Advances and all other amounts payable
under this Agreement.



                                      -65-
<PAGE>   71

         Section 8.06. Non-Reliance on Agent and Other Banks. Each Bank agrees
that it has, independently and without reliance on the Agent or any other Bank,
and based on such documents and information as it has deemed appropriate, made
its own credit analysis of the Credit Parties and their Subsidiaries and
decision to enter into this Agreement and that it will, independently and
without reliance upon the Agent or any other Bank, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own analysis and decisions in taking or not taking action under the Credit
Documents. Except for notices, reports, and other documents and information
expressly required to be furnished to the Banks by the Agent hereunder, the
Agent shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning the affairs, financial condition, or
business of any Credit Party or any of its Subsidiaries or affiliates that may
come into the possession of the Agent or any of its affiliates.

         Section 8.07. Resignation of Agent and Issuing Bank. The Agent and the
Issuing Bank may resign at any time by giving notice thereof to the Banks and
the Borrower. Upon any such resignation, the Majority Banks shall have the right
to appoint a successor Agent or Issuing Bank (in each case, so long as no
Default has occurred and is continuing, subject to the consent of the Borrower
which shall not be unreasonably withheld). If no successor Agent or Issuing Bank
shall have been so appointed by the Majority Banks and shall have accepted such
appointment within 30 days after the retiring Agent's or Issuing Bank's giving
of notice of resignation, then the retiring Agent or Issuing Bank may, on behalf
of the Banks, appoint a successor Agent or Issuing Bank (in each case, so long
as no Default has occurred and is continuing, subject to the consent of the
Borrower which shall not be unreasonably withheld) which shall be an Eligible
Assignee and, in the case of the Issuing Bank, a Bank. Upon the acceptance of
any appointment as Agent or Issuing Bank hereunder by a successor, such
successor shall thereupon succeed to and become vested with all the rights,
powers, discretion, privileges, and duties of the retiring Agent or Issuing
Bank, and the retiring Agent or Issuing Bank shall be discharged from its duties
and obligations hereunder and under the other Credit Documents, except that the
retiring Issuing Bank shall remain the Issuing Bank with respect to any Letters
of Credit issued by it and outstanding on the effective date of its resignation
and the provisions affecting the Issuing Bank with respect to such Letters of
Credit shall inure to the benefit of the retiring Issuing Bank until the
termination of all such Letters of Credit. After any retiring Agent's or Issuing
Bank's resignation hereunder as Agent or Issuing Bank, the provisions of this
Article VIII shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Agent or Issuing Bank.

         Section 9.01. Amendments, Etc. No amendment or waiver of any provision
of this Agreement, the Notes, or any other Credit Document, nor consent to any
departure by the Borrower or any other Credit Party therefrom, shall in any
event be effective unless the same shall be in writing and signed by the
Majority Banks and the Borrower, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no amendment, waiver or consent shall, unless in
writing and signed by all the Banks and the Borrower, do any of the following:
(a) waive any of the conditions specified in Section 3.01 or 3.02, (b) increase
the Commitments of the Banks, (c) reduce the principal of, or interest on, the
Notes or the Swing Note or any fees or other amounts payable hereunder or under
any other Credit Document, (d) postpone any date fixed for any payment of
principal of, or interest on, the Notes or the Swing Note or any fees or other
amounts payable hereunder, (e) change the number of Banks which shall be
required for the Banks or any of them to take any action hereunder or under any
other Credit Document, (f) amend Section 2.12 or this Section 9.01, (g) release
any Collateral or any Credit Party from its obligations under any Credit
Document to which it is a party, except pursuant to the terms of the applicable
Credit Document; or (h) amend the definition of "Majority Banks"; and provided,
further, that no amendment, waiver or consent shall, unless in writing and
signed by the Agent or the Issuing Bank in addition to the Banks required above
to take such action, affect the rights or duties of the Agent or the Issuing
Bank, as the case may be, under this Agreement or any other Credit Document.

         Section 9.02. Notices, Etc. All notices and other communications shall
be in writing (including telecopy or telex) and mailed, telecopied, telexed,
hand delivered or delivered by a nationally recognized overnight courier, if to
the Borrower or to a Guarantor, at the Borrower's address at 545 E. John
Carpenter Freeway, Suite 1570, Irving, Texas 75062, Attention: Mr. Danny

party in a written notice to the other parties. All such notices and
communications shall, when mailed, telecopied, telexed, hand-delivered, or
delivered by overnight courier, be effective three days after deposited in the
mails, when telecopy transmission is completed, when confirmed by telex
answer-back or when delivered, respectively, except that notices and
communications to the Agent pursuant to Article II or VIII shall not be
effective until received by the Agent.

         Section 9.03. No Waiver; Remedies. No failure on the part of any Bank,
the Agent, or the Issuing Bank to exercise, and no delay in exercising, any
right hereunder or under any Note or the Swing Note shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right preclude any
other or further exercise thereof or the exercise of any other right. The
remedies provided in this Agreement are cumulative and not exclusive of any
remedies provided by law.

         Section 9.04. Costs and Expenses. The Borrower agrees to pay on demand
all costs and expenses of the Agent in connection with the syndication,
preparation, execution, delivery, administration, modification, and amendment of
this Agreement, the other Credit Documents, and the other documents to be
delivered hereunder, including, without limitation, the reasonable fees and
expenses of counsel for the Agent (including the cost of internal counsel) with
respect thereto and with respect to advising the Agent as to its rights and
responsibilities under the Credit Documents. The Borrower further agrees to pay
on demand all costs and expenses of the Agent, the Issuing Bank and the Banks,
if any (including, without limitation, reasonable attorneys' fees and expenses
and the cost of internal counsel), in connection with the enforcement (whether
through negotiations, legal proceedings, or otherwise) of the Credit Documents
and the other documents to be delivered hereunder. Without prejudice to the
survival of any other agreement of the Borrower hereunder, the agreements and
obligations of the Borrower contained in this Section 9.04 shall survive the
payment in full of the Advances and all other amounts payable under this
Agreement.

         Section 9.05. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Borrower and the Agent, and when the
Agent shall have, as to each Bank, either received a counterpart of this
Agreement executed by such Bank or been notified by such Bank that such Bank has
executed it and thereafter shall be binding upon and inure to the benefit of the
Borrower, the Agent, the Issuing Bank, and each Bank and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights or delegate its duties under this Agreement or any interest in
this Agreement without the prior written consent of each Bank.

         Section 9.06.     Bank Assignments and Participations.

         (a) Assignments. Each Bank may assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Advances, its Note, and its
Commitment); provided, however, that

               (i) each such assignment shall be to an Eligible Assignee;

              (ii) except in the case of an assignment to another Bank or an
         assignment of all of a Bank's rights and obligations under this
         Agreement, any such partial assignment shall be in an amount equal to
         at least $5,000,000.00 and in integral multiples of $1,000,000.00 in
         excess thereof;

             (iii) each such assignment by a Bank shall be of a constant, and
         not varying, percentage of all of its rights and obligations under this
         Agreement and the Notes (other than 


                                      -68-
<PAGE>   74

         rights of reimbursement and indemnity arising before the effective date
         of such assignment) and shall be of an equal pro rata share of the
         Assignor's interest in the Revolving Credit Advances, Letter of Credit
         Exposure, and Commitments; and

              (iv) the parties to such assignment shall execute and deliver to
         the Agent for its acceptance an Assignment and Acceptance in the form
         of the attached Exhibit A, together with any Note subject to such
         assignment and a processing fee of $3,500.

Upon execution, delivery, and acceptance of such Assignment and Acceptance and
payment of the processing fee, the assignee thereunder shall be a party to this
Agreement and, to the extent of such assignment, have the obligations, rights,
and benefits of a Bank hereunder and the assigning Bank shall, to the extent of
such assignment, relinquish its rights and be released from its obligations
under this Agreement. Upon the consummation of any assignment pursuant to this
Section, the assignor, the Agent and the Borrower shall make appropriate
arrangements so that, if required, new Notes are issued to the assignor and the
assignee. If the assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall deliver to the Borrower and the
Agent certification as to exemption from deduction or withholding of Taxes in
accordance with Section 2.11.

         (b) The Register. The Agent shall maintain a copy of each Assignment
and Acceptance delivered to and accepted by it and a register for the
recordation of the names and addresses of the Banks and the Commitment of, and
principal amount of the Advances owing to, each Bank from time to time (the
"Register"). The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and the Borrower, the Agent and the Banks may
treat each Person whose name is recorded in the Register as a Bank hereunder for
all purposes of this Agreement. The Register shall be available for inspection
by the Borrower or any Bank at any reasonable time and from time to time upon
reasonable prior notice.

         (c) Procedures. Upon its receipt of an Assignment and Acceptance
executed by the parties thereto, together with any Note subject to such
assignment and payment of the processing fee, the Agent shall, if such
Assignment and Acceptance has been completed and is in substantially the form of
Exhibit A, (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register and (iii) give prompt notice
thereof to the parties thereto.

         (d) Participations. Each Bank may sell participations to one or more
Persons in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and its Advances); provided,
however, that (i) such Bank's obligations under this Agreement shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties
to this Agreement for the performance of such obligations, (iii) the participant
shall be entitled to the benefit of the yield protection provisions contained in
Section 2.09 and the right of set-off contained in Section 7.06, and (iv) the
Borrower shall continue to deal solely and directly 


                                      -69-
<PAGE>   75

with such Bank in connection with such Bank's rights and obligations under this
Agreement, and such Bank shall retain the sole right to enforce the obligations
of the Borrower relating to its Advances and its Note and to approve any
amendment, modification, or waiver of any provision of this Agreement (other
than amendments, modifications, or waivers decreasing the amount of principal of
or the rate at which interest is payable on such Advances or Note, extending any
scheduled principal payment date or date fixed for the payment of interest on
such Advances or Note, or extending its Commitment).

         (e) Federal Reserve Bank. Notwithstanding any other provision set forth
in this Agreement, any Bank may at any time assign and pledge all or any portion
of its Advances and its Note to any Federal Reserve Bank as collateral security
pursuant to Regulation A and any Operating Circular issued by such Federal
Reserve Bank. No such assignment shall release the assigning Bank from its
obligations hereunder.

         (f) Confidentiality. Any Bank may furnish any information concerning
the Borrower or any of its Subsidiaries in the possession of such Bank from time
to time to assignees and participants (including prospective assignees and
participants), subject, however, to the provisions of Section 9.08.

         Section 9.07. INDEMNIFICATION. THE BORROWER AGREES TO INDEMNIFY AND
HOLD HARMLESS THE AGENT, THE ISSUING BANK, THE ARRANGER, AND EACH BANK AND EACH
OF THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
AND ADVISORS (EACH AN "INDEMNIFIED PARTY") FROM AND AGAINST ANY AND ALL CLAIMS,
DAMAGES, LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING, WITHOUT
LIMITATION, (A) REASONABLE ATTORNEYS' FEES, INCLUDING THE ALLOCATED COST OF
INTERNAL COUNSEL, AND (B) SETTLEMENT COSTS) THAT MAY BE INCURRED BY OR ASSERTED
OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE ARISING OUT OF OR IN
CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN CONNECTION
WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN
CONNECTION THEREWITH) THE CREDIT DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED
HEREIN OR THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE ADVANCES (INCLUDING
ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY),
EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS
FOUND IN A FINAL ORDER OR JUDGMENT BY A COURT OF COMPETENT JURISDICTION OR OTHER
TRIBUNAL OR ARBITRATION PANEL (OR, IF SUCH FINAL ORDER OR JUDGMENT IS LATER
REVERSED, BY A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT
JURISDICTION) OR BY AGREEMENT TO HAVE (A) RESULTED PRIMARILY FROM AN INDEMNIFIED
PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OR (B) ARISEN OUT OF 


                                      -70-
<PAGE>   76

A CLAIM AMONG INDEMNIFIED PARTIES AND THEIR STOCKHOLDERS. IN THE CASE OF AN
INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN THIS
SECTION 9.07 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT SUCH
INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY THE BORROWER, ITS
DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER PERSON
OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE
TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. EACH PARTY TO THIS AGREEMENT
AGREES NOT TO ASSERT ANY CLAIM AGAINST THE BORROWER OR ANY OF ITS SUBSIDIARIES,
THE AGENT, THE ISSUING BANK, THE ARRANGER, ANY BANK, ANY OF THEIR AFFILIATES, OR
ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS, AGENTS, AND
ADVISERS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL, OR
PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE CREDIT DOCUMENTS,
ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR PROPOSED USE OF THE
PROCEEDS OF THE ADVANCES.

         Section 9.08. Confidentiality. The Agent and each Bank (each, a
"Lending Party") agrees to keep confidential any information furnished or made
available to it by or on behalf of the Borrower or any of its Subsidiaries
pursuant to this Agreement that is marked confidential; provided that nothing
herein shall prevent any Lending Party from disclosing such information (a) to
any other Lending Party or any affiliate of any Lending Party, or any officer,
director, employee, agent, or advisor of any Lending Party or affiliate of any
Lending Party, (b) to any other Person if reasonably incidental to the
administration of the credit facility provided herein, (c) as required by any
law, rule, or regulation, (d) upon the order of any court or administrative
agency, (e) upon the request or demand of any regulatory agency or authority,
(f) that is or becomes available to the public or that is or becomes available
to any Lending Party other than as a result of a disclosure by any Lending Party
prohibited by this Agreement, (g) in connection with any litigation to which
such Lending Party or any of its affiliates may be a party, (h) to the extent
necessary in connection with the exercise of any remedy under this Agreement or
any other Loan Document, and (i) subject to provisions substantially similar to
those contained in this Section, to any actual or proposed participant or
assignee.

         Section 9.09. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties to this Agreement in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

         Section 9.10. Survival of Representations, etc. All representations and
warranties contained in this Agreement or made in writing by or on behalf of the
Borrower in connection herewith shall survive the execution and delivery of this
Agreement and the Credit Documents, the making of the 


                                      -71-
<PAGE>   77

Advances and any investigation made by or on behalf of the Banks, none of which
investigations shall diminish any Bank's right to rely on such representations
and warranties. All obligations of the Borrower provided for in Sections 2.08,
2.09, 2.11(c), 9.04 and 9.07 and of the Agent and the Banks provided for in
Section 9.08 (but only for one year after repayment in full of the Obligations)
shall survive any termination of this Agreement and repayment in full of the
Obligations.

         Section 9.11. Severability. In case one or more provisions of this
Agreement or the other Credit Documents shall be invalid, illegal or
unenforceable in any respect under any applicable law, the validity, legality
and enforceability of the remaining provisions contained herein or therein shall
not be affected or impaired thereby.

         Section 9.12. Business Loans. The Borrower warrants and represents that
the Loans evidenced by the Notes are and shall be for business, commercial,
investment or other similar purposes and not primarily for personal, family,
household or agricultural use, as such terms are used in Chapter One ("Chapter
One") of the Texas Credit Code. At all such times, if any, as Chapter One shall
establish a Maximum Rate, the Maximum Rate shall be the "indicated rate ceiling"
(as such term is defined in Chapter One) from time to time in effect.


                                      -72-
<PAGE>   78


         Section 9.13. Usury Not Intended. It is the intent of the Borrower and
each Bank in the execution and performance of this Agreement and the other
Credit Documents to contract in strict compliance with applicable usury laws,
including conflicts of law concepts, governing the Advances and Swing Loans of
each Bank including such applicable laws of the State of Texas, if any, and the
United States of America from time to time in effect. In furtherance thereof,
the Banks and the Borrower stipulate and agree that none of the terms and
provisions contained in this Agreement or the other Credit Documents shall ever
be construed to create a contract to pay, as consideration for the use,
forbearance or detention of money, interest at a rate in excess of the Maximum
Rate and that for purposes of this Agreement "interest" shall include the
aggregate of all charges which constitute interest under such laws that are
contracted for, charged or received under this Agreement; and in the event that,
notwithstanding the foregoing, under any circumstances the aggregate amounts
taken, reserved, charged, received or paid on the Advances, include amounts
which by applicable law are deemed interest which would exceed the Maximum Rate,
then such excess shall be deemed to be a mistake and each Bank receiving same
shall credit the same on the principal of its Notes (or if such Notes shall have
been paid in full, refund said excess to the Borrower). In the event that the
maturity of the Notes are accelerated by reason of any election of the holder
thereof resulting from any Event of Default under this Agreement or otherwise,
or in the event of any required or permitted prepayment, then such consideration
that constitutes interest may never include more than the Maximum Rate and
excess interest, if any, provided for in this Agreement or otherwise shall be
canceled automatically as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited on the applicable Notes (or, if the
applicable Notes shall have been paid in full, refunded to the Borrower of such
interest). In determining whether or not the interest paid or payable under any
specific contingencies exceeds the Maximum Rate, the Borrower and the Banks
shall to the maximum extent permitted under applicable law amortize, prorate,
allocate and spread in equal parts during the period of the full stated term of
the Notes all amounts considered to be interest under applicable law at any time
contracted for, charged, received or reserved in connection with the
Obligations. The provisions of this Section shall control over all other
provisions of this Agreement or the other Credit Documents which may be in
apparent conflict herewith.

         Section 9.14. Governing Law. This Agreement and the other Credit
Documents shall be governed by, and construed and enforced in accordance with,
the laws of the State of New York.

         Section 9.15. Waiver of Jury. EACH OF THE BORROWER, THE OTHER CREDIT
PARTIES, THE BANKS, THE AGENT, AND THE ISSUING BANK HEREBY IRREVOCABLY WAIVES
ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING
OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, OR ANY OF THE
TRANSACTIONS CONTEMPLATED HEREBY.

         PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A
LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN AGREEMENT EXCEEDS
$50,000.00 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING
AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY'S AUTHORIZED REPRESENTATIVE.

         THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO
THE PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN
AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY
AND MERGED INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT
DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE
PARTIES (AND SUPERSEDE THE COMMITMENT LETTER DATED MAY 3, 1999) AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                                    GUARANTY


         This Guaranty dated as of March 31, 1999 ("Guaranty") is by each
Subsidiary of the Borrower (as defined below) listed on the signature page
(each a "Guarantor" and collectively the "Guarantors"), in favor of the Agent
for the Banks referred to below.

                                  INTRODUCTION

         A. This Guaranty is given in connection with the Credit Agreement
dated as of March 31, 1999 (as the same may be amended or modified from
time-to-time, the "Credit Agreement") among Advance Paradigm, Inc., a Delaware
corporation ("Borrower"), the Banks, and NationsBank, N.A., as agent for the
Banks ("Agent").

         B. The Borrower is the principal financing entity for all capital
requirements of its Subsidiaries, and from time-to-time the Borrower has made
capital contributions and advances to its Subsidiaries, including each of the
Guarantors. Each Guarantor is a wholly-owned subsidiary of the Borrower and
will derive substantial direct and indirect benefit from the transactions
contemplated by the Credit Agreement.

         C. Under the Credit Agreement, it is a condition to the making of the
Advances by the Banks, the issuance of the Letters of Credit by the Issuing
Bank, and the making of Swing Loans by the Agent that each of the Guarantors
shall have executed and delivered this Guaranty.

         Therefore, in order to induce the Banks to make the Advances, the
Issuing Bank to issue Letters of Credit and the Agent to make Swing Loans, each
of the Guarantors hereby agrees with Agent for its benefit and the ratable
benefit of the Banks as follows:

Section 1. Definitions. Unless otherwise defined, capitalized terms are defined
in the Credit Agreement.

Section 2. Guaranty. Each Guarantor hereby unconditionally guarantees the
punctual payment when due, whether at stated maturity, by acceleration or
otherwise, of all obligations of the Borrower now or hereafter existing under
the Credit Agreement, the Notes, the Swing Notes and any other Credit Document,
whether for principal, Reimbursement Obligations, obligations under any
Derivatives executed with a Bank or an Affiliate of a Bank, interest, fees,
expenses, or otherwise (such obligations being the "Guaranteed Obligations"),
and any and all expenses (including reasonable counsel fees and expenses)
incurred by the Agent, the Issuing Bank, or any Bank in enforcing any rights
under this Guaranty. Each Guarantor agrees that this Guaranty is a guarantee of
payment, not of collection and that each Guarantor is primarily liable for the
payment of the Guaranteed Obligations.

Section 3. Limit of Liability. The obligations of the each Guarantor hereunder
shall be limited to an aggregate amount equal to the largest amount that would
not render its obligations hereunder subject to avoidance under Section 548 of
the United States Bankruptcy Code or any comparable provisions of any
applicable state law.

Section 4. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the terms of the Credit
Agreement and the other Credit Documents, regardless of any law, regulation, or
order now or hereafter in effect in any jurisdiction affecting any of such
terms or the rights of the Agent, the Issuing Bank, or the Banks with respect
thereto. The liability of each Guarantor under this Guaranty shall be absolute
and unconditional irrespective of:

                  (a) any lack of validity or enforceability of the Credit
Agreement, any other Credit Document, or any other agreement or instrument
relating thereto;

                  (b) any change in the time, manner, or place of payment of,
or in any other term of, any of the Guaranteed Obligations, any increase,
reduction, extension, or rearrangement of the Guaranteed Obligations, or any
other amendment or waiver of or any consent to departure from the Credit
Agreement or any Credit Document;

                  (c) any exchange, release, or nonperfection of any
collateral, or any release or amendment or waiver of or consent to departure
from any other Guaranty, for any of the Guaranteed Obligations; or

                  (d) any other circumstances which might otherwise constitute
a defense available to, or a discharge of the Borrower or a Guarantor.

Section 5. Certain Waivers.

         5.01. Notice. Each Guarantor hereby waives promptness, diligence,
notice of acceptance, notice of acceleration, notice of intent to accelerate,
and any other notice with respect to any of the Guaranteed Obligations and this
Guaranty.

                                      -2-

         5.02. Other Remedies. Each Guarantor hereby waives any requirement
that the Agent, the Issuing Bank, or any Bank protect, secure, perfect, or
insure any Lien or any Property subject thereto or exhaust any right or take
any action against the Borrower or any other Person or any collateral.

         5.03. Subrogation. (a) Until the irrevocable payment in full of the
Guaranteed Obligations, none of the Guarantors will take any action pursuant to
any claim or rights which it may acquire against the Borrower or any other
Guarantor that arise from each Guarantor's obligations under this Guaranty or
any other Credit Document, including, without limitation, any right of
subrogation (including, without limitation, any statutory rights of subrogation
under Section 509 of the Bankruptcy Code, 11 U.S.C. Section 509, or otherwise),
reimbursement, exoneration, contribution, indemnification or any right to
participate in any claim or remedy of the Agent, the Issuing Bank, or any Bank
against the Borrower or any collateral, if any, which the Agent, the Issuing
Bank, or any Bank now has or acquires. If any amount shall be paid to any
Guarantor in violation of the preceding sentence and the Guaranteed Obligations
shall not have been paid in full, such amount shall be held in trust for the
benefit of the Agent, the Issuing Bank, and the Banks, and shall promptly be
paid to the Agent for the benefit of the Agent, the Issuing Bank, and the Banks
to be applied to the Guaranteed Obligations, whether matured or unmatured, as
the Agent may elect. Each Guarantor acknowledges that it will receive direct
and indirect benefits from the financing arrangements contemplated by the
Credit Agreement and that the waiver set forth in this Section 5.03(a) is
knowingly made in contemplation of such benefits.

                  (b) Each Guarantor agrees that, to the extent that any
Borrower makes payments to the Agent, the Issuing Bank, or any Bank, or the
Agent, the Issuing Bank, or any Bank receives any proceeds of collateral, and
such payments or proceeds or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, or otherwise required to
be repaid, then to the extent of such repayment the Guaranteed Obligations
shall be reinstated and continued in full force and effect as of the date such
initial payment or collection of proceeds occurred. EACH GUARANTOR SHALL DEFEND
AND INDEMNIFY THE AGENT, THE ISSUING BANK, AND EACH BANK (EACH AN "INDEMNIFIED
PARTY") FROM AND AGAINST ANY CLAIM OR LOSS UNDER THIS SUBSECTION 5.03(b)
(INCLUDING REASONABLE ATTORNEYS' FEES AND EXPENSES) IN THE DEFENSE OF ANY SUCH
ACTION OR SUIT, INCLUDING LOSSES, LIABILITIES, CLAIMS, DAMAGES, OR EXPENSES
INCURRED BY REASON OF NEGLIGENCE OF THE PERSON TO BE INDEMNIFIED, BUT EXCLUDING
ANY SUCH LOSSES, LIABILITIES, CLAIMS, 

                                      -3-

<PAGE>   4


DAMAGES, OR EXPENSES (A) INCURRED BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF AN INDEMNIFIED PARTY OR (B) ASSERTED BY AN INDEMNIFIED PARTY OR A
STOCKHOLDER OR AFFILIATE THEREOF AGAINST AN INDEMNIFIED PARTY.

Section 6. Representations and Warranties. Each Guarantor hereby represents and
warrants as follows:

                  (a) Corporate Authority. Each Guarantor is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization. The execution, delivery and performance by each Guarantor of this
Guaranty are within each Guarantor's powers, have been duly authorized by all
necessary action, and do not (i) contravene (A) each Guarantor's charter or
bylaws or (B) any law or material contractual restriction affecting each
Guarantor or its Property, the contravention of which would reasonably be
expected to cause a Material Adverse Change, or (ii) result in or require the
creation or imposition of any Lien prohibited by the Credit Agreement.

                  (b) Government Approval. No authorization or approval or
other action by, and no notice to or filing with, any Governmental Authority is
required for the due execution, delivery, and performance by each of the
Guarantors of this Guaranty.

                  (c) Binding Obligations. This Guaranty is the legal, valid,
and binding obligation of each Guarantor enforceable against each Guarantor in
accordance with its terms subject to the effect of any applicable bankruptcy,
insolvency, reorganization, moratorium, or similar law affecting creditors'
rights (whether considered in a proceeding at law or in equity).

Section 7. Covenants. Each Guarantor will comply with all provisions of
Articles V and VI of the Credit Agreement to the extent such Sections are
applicable to each Guarantor.

Section 8. Miscellaneous.

         8.01. Amendments, Etc. No amendment or waiver of any provision of this
Guaranty nor consent to any departure by each of the Guarantors therefrom shall
be effective unless the same shall be in writing and signed by the Agent,
Majority Banks and the Borrower, provided that any amendment or waiver
releasing any Guarantor from any liability hereunder shall be signed by all the
Banks and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

      8.02. Addresses for Notices. All notices and other communications
provided for hereunder shall be in writing, including telegraphic
communication, and delivered or teletransmitted to the addresses set forth next
to the signatures below, or to such other address as shall be designated by
each Guarantor or Agent in written notice to the other party. All such notices
and other communications shall be effective when delivered or teletransmitted
to the above addresses.

         8.03. No Waiver; Remedies. No failure on the part of the Agent, the
Issuing Bank, or any Bank to exercise, and no delay in exercising, any right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right hereunder preclude any other or further exercise thereof
or the exercise of any other right. The remedies herein provided are cumulative
and not exclusive of any remedies provided by law.

         8.04. Right of Set-Off. Upon (a) the occurrence and during the
continuance of any Event of Default and (b) the making of the request or the
granting of the consent, if any, specified by Section 7.02 of the Credit
Agreement to authorize the Agent to declare the Notes, the Swing Notes, and any
other amount payable under the Credit Agreement due and payable pursuant to the
provisions of such Section 7.02 or the automatic acceleration of the Notes, the
Swing Notes, and all amounts payable under the Credit Agreement pursuant to
Section 7.03 thereunder, the Agent, the Issuing Bank, and each Bank is hereby
authorized at any time, to the fullest extent permitted by law, to set off and
apply any deposits (general or special, time or demand, provisional or final,
but excluding deposits that such Bank knows or, with reasonable inquiry should
know, are held by Borrower in a fiduciary capacity for the benefit of others)
and other indebtedness owing by the Agent, the Issuing Bank, or such Bank to
the account of each Guarantor against any and all of the obligations of each
Guarantor under this Guaranty, irrespective of whether or not the Agent, the
Issuing Bank, or such Bank shall have made any demand under this Guaranty and
although such obligations may be contingent and unmatured. The Agent, the
Issuing Bank, and each Bank 



                                      -5-

<PAGE>   6


agrees promptly to notify each Guarantor after any such set-off and application
made by the Agent, the Issuing Bank, or such Bank provided that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of the Agent, the Issuing Bank, and the Banks under this Section
8.04 are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which the Agent, the Issuing Bank, or the
Banks may have.

         8.05. Continuing Guaranty; Transfer of Interest. This Guaranty shall
create a continuing guaranty and shall (a) remain in full force and effect
until payment in full and termination of the Guaranteed Obligations, (b) be
binding upon each Guarantor, its successors, and assigns, and (c) inure,
together with the rights and remedies of the Agent hereunder, to the benefit of
the Agent, the Issuing Bank, the Banks, and their respective successors and
Eligible Assignees. Without limiting the generality of the foregoing clause,
when any Bank assigns or otherwise transfers any interest held by it under the
Credit Agreement or other Credit Document to any other Person (pursuant to
Section 9.06 of the Credit Agreement), that other Person shall thereupon become
vested with all the benefits held by such Bank under this Guaranty. Upon the
payment in full and termination of the Guaranteed Obligations, the guaranty
granted hereby shall terminate and all rights hereunder shall revert to each
Guarantor to the extent such rights have not been applied pursuant to the terms
hereof. Upon any such termination, the Agent will, at each Guarantor's expense,
execute and deliver to each Guarantor such documents as such Guarantor shall
reasonably request and take any other actions reasonably requested to evidence
or effect such termination.

         8.06. Governing Law. This Guaranty shall be governed by, and construed
and enforced in accordance with, the laws of the State of New York.
