PART I
ITEM 1.   BUSINESS

Introduction

     Option Care, Inc. (together with its subsidiaries, collectively "Option
Care" or "the Company") is a full service home healthcare business providing
services through its owned locations and through its supporting franchise
network.  The Company was incorporated in Delaware on July 9, 1991.  The
Company's predecessor was incorporated in California in January 1984.

     Option Care has established a nationwide presence.  The advantages of a
national presence include a strong brand identity and accessibility for managed
care payors and customers.  As of December 31, 1996, 186 Option Care locations
were operating in 37 states.  Existing offices include 164 locations owned and
operated by franchise owners and 22 locations owned and operated by the Company.
Aggregate gross billings for patient care services for all owned and franchised
Option Care offices were approximately $255,000,000 for the year ended December
31, 1996.

     The Company owns and operates alternate site healthcare businesses.  The
Company operated 22 such locations at December 31, 1996.  These Company-owned
locations offer infusion therapy services, nursing, respiratory therapy and
durable medical equipment.  The Company expects to increase the number of its
owned locations through acquisitions.

     The Company and its franchise network provide managed care companies and
payors with one-stop shop services.  Many referral sources, such as hospitals,
physicians, third-party payors and case management companies, may prefer making
patient referrals to multi-office companies or systems, such as the Option Care
system.  Under the Company's OPTIONET program, the Company has contracted with
certain regional and national third-party payors and case management companies
to refer patients to participating Option Care locations.

     The Company is committed to the provision of high quality care and believes
that an important measure of quality in the home healthcare industry is
accreditation by the Joint Commission on Accreditation of Healthcare
Organizations ("JCAHO") or similar organizations.  As of December 31, 1996, 165
of the Company's franchised and owned locations were accredited.  All new
franchises since April 1, 1990 have been required by the Company to apply for
accreditation within their first year of operation.  The Company's goal is for
substantially all Option Care locations to become accredited.

     The Company plans to continue to expand and develop its business through
(i) acquiring selected existing franchised locations or other providers of home
healthcare services, (ii) providing managed care companies and payors one-stop
services through owned or networked providers, (iii) entering into strategic
alliances with outpatient services providers, hospitals, physicians and payors,
and (iv) increasing the volume of current therapies and adding new therapies and
services.  Additional debt or equity financing may be required to carry out the
Company's future acquisition strategy.  The Company can give no guarantees that
such financing will be available or available at an acceptable cost.

THE HOME HEALTHCARE MARKET

     Home healthcare principally involves the in-home or non-hospital provision
of nursing services, infusion therapy, respiratory services and durable medical
equipment.  These services often begin during hospitalization and continue in
the 

                                       3
<PAGE>
 
home or other non-acute care setting, but may also be provided following
outpatient surgery or in connection with the treatment of conditions not
requiring hospitalization.

     The market for home healthcare services has experienced significant growth.
The Company believes that the following factors have contributed to this growth:
(i) cost containment efforts by third-party payors promoting use of relatively
less expensive home healthcare therapy rather than longer hospital stays; (ii)
increased awareness and acceptance among physicians and third-party payors of
alternatives to in-hospital treatment; (iii) the desire of patients to be
treated at home; and (iv) improved technology.  Consolidation of providers has
been a recent dominant trend in the home healthcare industry.

SERVICES

     The Company is a full service home healthcare provider with a supporting
franchise network.  The Company offers infusion therapy, nursing services,
respiratory therapy and durable medical equipment through its owned offices and
infusion therapy through its franchise network.  The Company's franchise network
locations compound, dispense and administer pharmaceuticals, sell medical
supplies, sell or rent associated medical equipment, provide skilled nursing
services, train patients and their care givers, consult with attending
physicians, and process reimbursement claims.  The decision to proceed with
alternate-site therapies is generally made jointly by the patient, the attending
physician and a representative of the Option Care office involved.  This
decision involves obtaining and evaluating information about the patient's
medical history, care environment and insurance coverage, as well as discussing
the patient's or care giver's willingness and ability to participate in the
management of care in the home setting.

     The majority of the Company's patient care service revenue is derived from
home infusion therapy related services.  The principal home infusion therapies
include the following:

 Total Parenteral Nutrition ("TPN")

     TPN involves the intravenous administration of life sustaining nutrients to
patients whose digestive tracts are unable to function normally due to severe
gastrointestinal illness or injury.  In many cases the TPN patient's underlying
condition is chronic in nature and he or she may require TPN for life.

  Anti-infective Therapy

     Anti-infective therapy involves the parenteral administration of
antibiotics, antivirals and antifungals  to treat a variety of serious
infections such as those associated with AIDS, osteomyelitis, endocarditis,
urinary tract infection or wounds.  Anti-infective therapy is generally
administered in the patient's home as a continuation of therapy initiated on an
outpatient basis or during hospitalization.

                                       4
<PAGE>
 
 Pain Management

     Pain management therapy is the parenteral administration of analgesic drugs
to patients suffering from acute or chronic pain.  Specialized infusion devices
permit patients to control the administration of analgesic drugs to respond to
the severity of their pain.



Enteral Nutrition

     Enteral patients are usually unable to receive adequate nutrition orally
due to disorders including stroke, intestinal obstruction or cancer.  Patients
receive nutritional formulas via a tube placed directly into the stomach or
small intestine,  bypassing the dysfunctional portion of the patient's digestive
tract.

 Chemotherapy

     Chemotherapy is the parenteral administration of drugs to treat patients
suffering from cancer. As chemotherapy is commonly administered periodically for
several weeks or months, patients may receive their therapy regimen in alternate
settings.

     Other therapies provided by Option Care offices may include:  (i) hydration
therapy; (ii) blood components (packed red blood cells, Factor VIII and
immunoglobin); (iii) human growth hormone; (iv) aerosolized pentamidine for
prevention of pneumonia often contracted by AIDS patients; (v) intradialytic
parenteral nutrition for chronic kidney failure patients; (vi) deferoxamine for
patients with chronic iron overload; and (vii) pre-term labor monitoring and
tocolytic infusions for high-risk pregnancies.

     The following table sets forth the aggregate percentages of revenues by
home infusion therapy of Company-owned offices for the periods indicated:

     Approximately 20% of the Company's patient care service revenue is derived
from nursing services.  Option Care's nursing services include providing support
for  infusion therapies and providing traditional home health nursing services
in many markets.  These services include patient assessment, training,
monitoring, documentation and physician communication.  In addition to nursing
support for infusion therapies, many Option Care locations provide skilled
nursing care for a full range of other services, as well as private duty
nursing.

     In addition to the services mentioned above, Option Care derives
approximately 6% of its patient care service revenue from the sale of home
medical equipment (HME) and respiratory therapy.

FRANCHISING PROGRAM

     As of December 31, 1996, the Company had 165 franchise locations.  The
Company's current franchise agreement grants the franchise owner the authority
to own and operate an Option Care franchise within a granted territory for a 20-
year term.  The initial franchise fee for start-up franchises ranges from
$15,000 to $35,000 and is payable by the franchise owner upon execution of the
franchise agreement.  The exact amount of the initial franchise fee is
determined by the

                                       6
<PAGE>
 
Company based on the population in the territory granted to the franchise owner.
Conversion franchise fees are lower than those for start-ups.

     The Company's franchise agreements generally provide for royalties on a
sliding scale ranging from a high of 9% to a low of 2% of annual gross cash
receipts depending on the levels of such receipts, whether the franchise owner
conducted a similar business prior to the execution of the franchise agreement,
and other factors.

     Each Option Care office is required to maintain a licensed pharmacy
equipped to prepare sterile patient medications and parenteral solutions as
prescribed by the patient's physician.  Each location operates under a
confidential, proprietary system developed by the Company which includes
procedures for quality assurance, office administration and patient care,
consistency and uniformity of pharmaceuticals and offered services, initial
training and ongoing assistance.

Key employees of each franchised Option Care office, including pharmacists,
nurses, and managers, must complete initial training programs provided by the
Company.  In addition to required initial training, the Company offers advanced
training in selected topics to franchise owners and their employees.

     The Company furnishes Option Care franchisees with its system of training,
marketing and operating support services.  In addition, franchised locations
may, but are not required to, purchase or otherwise acquire from or through the
Company certain pharmaceuticals, supplies, and pharmacy-related equipment.  The
Company's initial training and ongoing support provided to its owned and
franchised locations stresses the importance of consistent quality and
responsive service.

     The Company's franchise agreements require, among other things, franchise
owners to meet the Company's policies on quality assurance, clinical services
and local marketing and to obtain specified liability insurance protecting the
franchise owner and the Company against claims arising out of the operation of
the franchised business.

     The Company  conducts franchise owner meetings on both regional and
national levels to provide operating assistance, information on new Option Care
programs, new marketing concepts and other assistance.  The Company also works
with its franchise owners' National Advisory Council in communicating with
franchise owners and receiving their recommendations for changes and
improvements to the Option Care system.

     The following table indicates the number of Option Care franchise locations
at the beginning of the year, the number of new franchises sold, the number of
franchises terminated or consolidated and the number of franchises at the end of
each year in the three-year period ended December 31, 1996:

REIMBURSEMENT FOR SERVICES

     Most of the patient care revenues of owned Option Care locations are
derived from third-party payors, such as insurance companies, health maintenance
organizations, self-insured employers, Medicare and Medicaid.  Where permitted
by law or contract, patients are billed for amounts not reimbursed by third-
party payors.  Private third-party payors typically reimburse a higher amount
and faster for a given service and provide a broader range of benefits than
government programs.

     Reimbursement from Medicare and Medicaid programs is subject to statutory
and regulatory requirements, administrative rulings, interpretations of policy,
implementation of reimbursement procedures, retroactive payment adjustments and
governmental funding restrictions, all of which may materially affect payments
to home healthcare providers.

     Reimbursement of home healthcare is covered to varying degrees by third-
party payors.  Obtaining reimbursement can be subject to delays and is not
always assured.  Slower receivable collections may result in a need for higher
levels of short-term financing.  Lack of adequate financing may limit growth.

     The following table sets forth the approximate percentages of revenues
attributable to private and government reimbursement sources for Company-owned
locations for the periods indicated:

SALES AND MARKETING

     Generating patient referrals is vital to the success of any home healthcare
business.  Option Care offices are required to employ sales personnel whose
primary responsibility is to market Option Care services to potential referral
sources.  Marketing efforts focus on area hospitals, physicians, managed-care
and other payors and case management companies.  The active role which general
managers and franchise owners typically play in the operation of the business
also helps create a focused effort on developing the market for each office.

     In 1991, the Company initiated a field sales and marketing program to
support the efforts of its franchise system.  The field staff focus varies with
the strategy of the Company.  Currently, the field staff assist Option Care
offices in developing business and marketing plans, marketing their services
locally, introducing additional therapies and services and coordinating regional
sales programs largely targeted to managed care organizations.

     The Company has established a program called OPTIONET, through which the
Company contracts with certain regional and national third-party payors (e.g.,
insurance companies, health maintenance organizations and large self-insured
employers) and case management companies to refer patients to participating
Option Care offices.  Under OPTIONET agreements, each participating Option Care
office provides local services for covered patients.  Based on payor preference
or requirements, Option Care offices bill the payor directly for services

                                       8
<PAGE>
 
rendered, or the Company arranges for a third-party billing service to bill the
payor for a billing fee.

     The Company maintains a National Advertising and Education Fund for
marketing the services of Option Care offices to patient referral sources such
as physicians, hospitals, nursing agencies, third-party payors and case
management companies, and for the cost of educational programs for franchise
owners.  Option Care offices are required to contribute at various rates up to 1
1/2% of gross receipts to these funds.


SUPPLIERS

     Option Care offices must acquire pharmaceuticals, supplies, equipment and
services relating to their businesses from suppliers which satisfy certain
standards and possess adequate quality controls.  The Company may derive revenue
through administrative fees received from contracted manufacturers.

     Neither the Company nor its franchises have experienced significant
difficulty in purchasing pharmaceuticals, supplies or equipment.  In the event
that current suppliers cease to sell pharmaceuticals, supplies or equipment to
the Company or its franchises, the Company believes that alternate sources can
be located without undue burden, which would adequately meet their needs.

GOVERNMENT REGULATION

 Health Care Regulation

     Home healthcare is subject to regulation by the various states in which the
Company and its franchise owners conduct their businesses, as well as by the
federal government.  Option Care locations are subject to state laws (including
licensing laws) governing pharmacies, home health agencies, nursing services,
health planning and professional conduct.  Each Option Care location must be
appropriately registered with the United States Food and Drug Administration and
Drug Enforcement Administration and comply with record keeping and inventory
requirements for the dispensing of controlled substances.  Although the Company
provides its franchised locations guidance in compliance with regulatory
requirements, it is not responsible for such compliance.  The failure of an
Option Care location to obtain, renew or maintain any required regulatory
approvals or licenses could adversely affect that location and could prevent
such location from offering services to patients.

     To the extent Option Care locations provide services under the Medicare and
Medicaid programs, they are subject to a broad body of laws regulating those
programs, including "fraud and abuse" laws.  Among other things, these laws
prohibit any bribe, kickback or rebate in return for the referral of Medicare or
Medicaid patients.  In addition, many of the states in which Option Care
locations operate have laws that prohibit certain direct or indirect payments or
fee-splitting arrangements between health care providers that are designed to
induce or encourage the referral of patients to, or the recommendation of, a
particular provider for medical products and services.  Bills have been
introduced in several states that would increase restrictions or prohibit
referrals where a physician has a financial relationship with the provider.  In
addition, some states restrict certain business relationships between physicians
and pharmacies.  These statutes vary from state to state.  The Company exercises
care in structuring its arrangements with health care providers and referral
sources to comply with the relevant statutes, but there can be no assurance that

                                       9
<PAGE>
 
such laws will ultimately be interpreted in a manner consistent with the
practices of the Company or the franchise owners.

     Other state and federal laws and regulations could also adversely affect
existing or future financial relationships between physicians and health care
businesses, including franchised businesses.  The Omnibus Reconciliation Act of
1993 prohibits physicians, subject to certain exceptions, who have a "financial
relationship" with an entity from referring patients to that entity for the
provision of "designated health services" which may be reimbursed by Medicare or
Medicaid.  The eleven "designated health services" include parenteral and
enteral nutrients, equipment and supplies; outpatient prescription  drugs; and
durable medical equipment.  With certain exceptions, this Act also requires
entities seeking payment from the Medicare and Medicaid programs to report any
ownership and compensation arrangements with physicians.  This federal law bars,
with limited exceptions, physician ownership of an Option Care franchised
business.

     The United States Department of Health and Human Services, Office of the
Inspector General ("OIG"), has been utilizing a civil statute, the False Claims
Act, in challenging Medicare billing practices.  In particular, the False Claims
Act provides that any person who knowingly presents, or causes to be presented,
to an officer or employee of the United States Government or a member of the
Armed Forces of the United States a false or fraudulent claim for payment or
approval is liable to the United States Government for a civil penalty of not
less than $5,000 and not more than $10,000, plus 3 times the amount of damages
which the Government sustains because of the act of that person.

     It is the Company's understanding that the OIG considers each claim that is
submitted for reimbursement to the Medicare program to be a claim for purposes
of the False Claims Act.  Accordingly, if 100 claims are submitted knowingly
containing false or fraudulent information, the party submitting the claim may
be liable for not only treble damages, but also $1,000,000 in fines.

     There are also various proposals under development or consideration to
enact health care reform.  In broad terms, most of these proposals are designed
to control health care costs through regulatory actions and/or market forces and
limit self-referrals.  Health care reform could impact providers of Option Care
services, although it is not possible at this time to predict the nature or
extent of any impact upon franchised businesses.

     The Company is unable to predict whether any new legislation or regulations
may be enacted in the future which may affect the business of the Company,
Option Care locations or the health care industry, including third-party
reimbursement. Accordingly, the Company cannot predict whether any such new
legislation or regulations would have a material adverse impact on the Company.

 Franchise Regulation

     The Company's franchising operations are subject to Federal Trade
Commission ("FTC") regulation and state laws which regulate the offer and sale
of franchises.  The Company is also subject to a number of state laws which
regulate substantive aspects of the relationship between franchisors and
franchise owners.

     The FTC's Trade Regulation Rule on Franchising (the "FTC Rule") requires
the Company to furnish prospective franchise owners with a franchise offering
circular containing information prescribed by the FTC Rule.  At least 12 states
presently regulate the offer and sale of franchises and, in almost all cases,
require registration of the franchise offering with state authorities.

                                       10
<PAGE>
 
     State laws which regulate the relationship between franchisors and
franchise owners presently exist in a substantial number of states.  Such laws
regulate the franchise relationship by, for example, requiring the franchisor to
deal with its franchise owners in good faith, prohibiting interference with the
right of free association among franchise owners, and limiting the imposition of
standard charges, royalties or fees.  These laws have not precluded the Company
from seeking franchise owners in any given area and have not had a significant
effect on the Company's operations.

     The Company is not aware of any pending franchise legislation which in its
view is likely to significantly affect the operations of the Company.  The
Company believes that its operations comply substantially with the FTC Rule and
applicable state franchise laws.

COMPETITION

     The home healthcare market is intensely competitive.  Although the market
is somewhat fragmented, there are several major providers of home healthcare
services and increasing pressures toward market consolidation.  Home Care
Magazine, in its December 1996 issue, named Option Care the 28th largest home
healthcare company.  Certain other national competitors are larger and have
greater resources than those of the Company.  Competition varies by market
location.  Option Care's competitors include numerous small, local companies and
physician groups, major national and regional companies, hospital-based
programs, and nursing agencies.  To the extent that the Company acquires or
franchises operations in new areas, the Company may face additional competition.

     In addition, new competitors may enter the home healthcare market and
existing competitors may expand the variety of services that they offer.  Option
Care locations compete on the basis of a number of factors, including quality,
consistency, responsiveness and diversity of services; geographic coverage; the
ability to develop and maintain goodwill or contractual relationships with
referral sources such as hospitals, managed care providers, physicians and other
related entities; and price.  Option Care continues to develop ways to present
comprehensive home healthcare services in response to payor interest in "one
stop shop" home care service.  Purchasing, diversification and network
development are alternative routes to providing this service.

SERVICE MARKS

     The Company has registered with the federal government OPTION CARE(R),
among others, as a service mark.  The Company believes that this service mark is
becoming increasingly recognized by many referral sources as representing a
reliable, cost-effective source of home healthcare services.  The Company
believes that its use of this service mark does not violate or otherwise
infringe on the rights of others.

EMPLOYEES

     At December 31, 1996, the Company employed 532 persons on a full-time basis
and 55 persons on a part-time basis.  Of the Company's full-time employees, 81
were corporate management and administrative personnel and the remaining 451
were 

                                       11
<PAGE>
 
employees of Company-owned locations, primarily in clinical, management and
administrative positions.

     The Company considers its employee relations to be good.  None of the
Company's employees are covered by a collective bargaining agreement.

INSURANCE

     The Company currently maintains insurance for general and professional
liability claims in an aggregate amount which it believes to be sufficient given
the nature of its business.  In addition, the Company maintains insurance for
vicarious liability of the Company, if any, for the acts and omissions of its
franchises, and the Company requires each franchise to maintain general
liability insurance and professional liability insurance on each of its
professionals, in each case covering both the franchise and the Company, with
coverage at levels which the Company believes to be sufficient.  These policies
generally provide coverage on a claims made or occurrence basis and have certain
exclusions from coverage.  These insurance policies must generally be renewed
annually.  There can be no assurance that insurance coverage will be adequate to
cover liability claims that may be asserted against the Company or that adequate
insurance will be available in the future at acceptable cost.  To the extent
that liability insurance is not adequate to cover liability claims against the
Company, the Company will be responsible for the excess.

ITEM 2.   PROPERTIES

     The Company maintains executive offices at 100 Corporate North, Suite 212,
Bannockburn, Illinois  60015, consisting of approximately 13,655 square feet of
leased space.

     At December 31, 1996, the Company owned operations located in Bullhead
City, AZ, Chico, CA, Columbia, MO, Bethlehem, PA, Horsham, PA,  Bellingham, WA,
Omaha, NE, Grand Junction, CO, Gadsden, AL, Houston, TX, Little Rock, AR,
Bellaire, TX, Bethel, OH, Milford, OH, Everett, WA, Oklahoma City, OK,  Tampa,
FL, Kirksville, MO, Jefferson City, MO, Ontario, CA, Kennewick, WA and Ft.
Myers, FL.  These facilities consist of approximately 124,522 square feet in
total.

     All the Company's offices and facilities are leased by the Company with
remaining lease terms ranging from six months to six years.  All the Company's
offices and facilities are in good condition and well maintained, and are
adequate to fulfill the operational needs of the Company for the foreseeable
future.

ITEM 3.   LEGAL PROCEEDINGS/LITIGATION

     On January 17, 1995, an action entitled Dennis H. Birenbaum v. Option Care,
Inc., Case No. 95-439, was filed with the District Court of Dallas County,
Texas. Plaintiff alleged breach of contract, promissory estoppel and negligent
misrepresentation concerning an alleged agreement for the sale and purchase of
Plaintiff's company.  In response, the Company produced evidence showing no
agreement was ever made. Dr. Birenbaum's lawsuit was dismissed and the Company
was awarded summary judgment by the Court.  Dr. Birenbaum has filed an appeal
which the Company is vigorously contesting.

                                       12

     On January 28, 1994, an action entitled George Harvey v. Option Care, Inc.,
et al. (U.S. District Court, Clark County, Nevada, Case No. A329456), was filed
against Option Care, Inc., Option Care Enterprises, Inc., a former employee of
Option Care, Inc., and the corporate owner of the Las Vegas Option Care Office
and two of its employees.  At the time the action was filed, Option Care
Enterprises, Inc. managed the Las Vegas Option Care Office through a management
agreement.  The plaintiff is pursuing claims for breach of contract, breach of
fiduciary duties, fraud, negligent misrepresentation and breach of implied
covenant of good faith and fair dealing relating to the performance of the
Management Agreement.  The Company has filed a motion to dismiss, which was
granted on April 1, 1994 regarding the alleged breach of fiduciary duty, breach
of contract and fraud.  There has been no subsequent pursuit of the remaining
claims.  Should the plaintiff pursue these claims in the future, the Company
will vigorously contest such claims.

     On August 29, 1991, an action entitled Ronald L. Rennick, et al. v. Option
Care, Inc., Case No. CV-S-91-1169 GEB-GGH, was filed in the United States
District Court, Eastern District of California.  Plaintiffs were owners of two
former Option Care franchises located in Oregon, and related persons and
entities which wanted to introduce alternate setting infusion care into Canada
and to expand their Option Care franchise holdings in the United States.
Following an amendment of their complaint, the dismissal of some of their
claims, and the withdrawal of other of their claims, plaintiffs pursued claims
for breach of contract, breach of the covenant of good faith and fair dealing,
breach of alleged fiduciary duties, promissory estoppel and violations of
California franchise laws.  Their claims were based on allegations that Option
Care breached an agreement with plaintiffs whereby plaintiffs acquired exclusive
rights for the Option Care system in Canada, rights to open 10 new Option Care
franchises in the United States, and rights to acquire 10 existing Option Care
franchises in the United States.  Plaintiffs alleged lost profits of $24.197
million.  Option Care denied the existence of any such agreement, and filed
counterclaims against plaintiffs, including claims for monies owed under two
terminated franchise agreements with certain of plaintiffs.  By order dated
September 28, 1993, the court granted Option Care's motion for summary judgment
on all counts of the amended complaint and entered judgment in favor of Option
Care on several of its counterclaims.  The plaintiffs appealed the district
court's ruling to the United States Court of Appeals for the Ninth Circuit,
which, on February 22, 1996, affirmed the district court's decision.  The
Plaintiffs then petitioned the Supreme Court of the United States for a writ of
certiorari.  The Supreme Court of the United Stated denied the petition for a
writ of certiorari on October 7, 1996.

     Despite the inherent uncertainties of litigation, management of the Company
at this time does not believe that the lawsuits will have a material adverse
impact on the financial condition of the Company.

     The Company is also a party to other legal proceedings incidental to its
business.  The Company does not believe that these other legal proceedings will
have a material adverse impact on its financial position or results of
operations.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

OVERVIEW

     Option Care, Inc. (the "Company") is a full service home healthcare
provider with a supporting franchise network.  The Company offers infusion
therapy, nursing services, respiratory therapy and durable medical equipment
through its owned locations and infusion therapy through its franchise network.
The Company has also developed capability to manage networks of outpatient
service providers.

RESULTS OF OPERATIONS

     The Company's revenues are derived primarily from three sources: (i)
patient care services from Company-owned offices, (ii) royalty fees and other
revenues from franchise owners and (iii) product sales to the franchised
locations.  Revenues from network management were immaterial during the
reporting periods. The following table sets forth the percentage relationships
that certain items from the Company's Consolidated Statements of Operations bear
to revenues for the years ended December 31, 1996, 1995, and 1994.  This
information should be read in conjunction with the Company's Consolidated
Financial Statements and Notes thereto contained elsewhere in this Annual Report
on Form 10-K:

1996 COMPARED TO 1995

     For 1996, total revenue rose 7.7 percent to $70,521,000 from $65,503,000 in
1995.  Patient care services revenue rose 16.8 percent, primarily reflecting the
results of 1996 acquisitions as well as a full year's operations of the
Company's 1995 acquisitions.  Product sales revenue decreased 15.5 percent or
$1,704,000 due primarily to management's  transition to direct billing of
franchisees by selected manufacturers, which was completed in mid-1996.  The
administrative fees that the Company recognizes from such sales are recorded as
other income rather than as revenue.  Management expects the transition to
continue to have a negative effect on gross profit but an immaterial effect on
net income.  Royalty fees and other revenue decreased 2.6 percent, reflecting
the acquisition of several large franchises in 1996.  The Company sold fourteen
new 

                                       19
<PAGE>
 
franchises during 1996, and terminated or consolidated fifteen franchises,
continuing the trend towards consolidation. The Company has only two franchise
agreements up for renewal before 2004. Management generally makes extensive
efforts to renew its franchise agreements, since existing franchises provide a
greater royalty stream than new franchises. The terms of the renewal agreements
may not be identical to those under existing agreements. Though the loss of
larger, mature franchises tends to reduce royalties, the Company expects
increased patient care services revenue to offset the decrease in royalty fees
and product sales revenue.

     Gross profit increased 5.1 percent for the year to $19,323,000, primarily
due to increased patient care services revenue.  As a percentage of revenues,
gross profit declined from 28.1 percent to 27.4 percent.  The decline in gross
margin is due primarily to changes in the Company's revenue mix, specifically
the decline in royalty fees and product sales coupled with growth in patient
care service revenue.  Revenues from patient care services (associated with
Company-owned Option Care offices) have a higher cost of revenue than the
Company's franchise business, which is generally associated with revenues from
royalty and other fees.  Three owned office locations were sold and three
locations closed in 1996 due to population demographics and financial trends
which limited the potential for long-term profitability.  These transactions
were part of management's program to improve profitability of Company operations
through a reduced cost structure.  Management will continue to evaluate the
profitability of operations as it also evaluates strategies to increase
revenues.

     Total operating expenses increased 183.7 percent to $37,661,000 from
$13,276,000 in 1995.  Selling, general and administrative expenses decreased 0.3
percent as a result of increased personnel productivity.  The Company's
provision for doubtful accounts increased 12.6% or $208,000, due to increased
patient care service revenue. Amortization of goodwill increased 5.0 percent due
to 1995 and 1996 acquisitions.  During 1996, the Company recognized $24,164,000
in non-cash charges relating to write-offs of goodwill.  This write-off
primarily relates to goodwill recorded through pushdown accounting for a change
of control in 1990, as well as goodwill related to prior year acquisitions.  The
write-off resulted from the Company's stated objective of purchasing existing
franchises as well as from evaluation of expected future cash flows for
purchased businesses.  If the effect of these 1996 charges is excluded, total
operating expenses increased 1.7 percent in 1996.

     The effective combined federal and state income tax rate was negative 12.8
percent  and 42.6 percent for 1996 and 1995, respectively.  The effective tax
rate is higher than the federal statutory tax rate of 34% due to state taxes and
to non-tax deductible expenses, primarily goodwill amortization.  Goodwill
amortization is a fixed expense, so the effective tax rate decreases as pre-tax
income increases.  The 1996 negative effective tax rate is due to the non-
deductible nature of the write-off of goodwill.  The Company had a net loss of
$20,256,000 in 1996 versus net income of $2,988,000 in 1995.  Net income for
1996 was $3,563,000 excluding the write-off of goodwill.

1995 COMPARED TO 1994

     For 1995, total revenue rose 5.6 percent to $65,503,000 from $62,019,000 in
1994.  Patient care services revenue rose 21.0 percent, primarily reflecting a
full year's operations of the Company's 1994 acquisitions as well as the results
of 1995 acquisitions.  Same store growth of patient care services revenue was
approximately 7.1 percent in 1995.  Product sales revenue decreased 28.6 percent
or $4,400,000 due primarily to management's  planned transition to direct
billing of franchisees by selected manufacturers.  The administrative fees that
the Company recognizes from such sales are recorded as other income rather than
as revenue.  Management expects the transition to continue to have a negative
effect on gross profit but an immaterial effect on net income.  Royalty fees and
other revenue increased 5.1 percent, reflecting increased fees earned from new
franchise sales.  The Company sold thirteen new franchises during 1995, and
terminated or consolidated twenty franchises, continuing the trend towards
consolidation.

     Gross profit decreased 1.5 percent for the year to $18,390,000, primarily
due to the planned decline in product sales.  This decline in gross profit was
substantially offset by increased vendor administration fees recorded as other
income.  As a percentage of revenues, gross profit declined from 30.1 percent to
28.1 percent.  The decline in gross margin is due primarily to changes in the
Company's revenue mix, specifically the decline in product sales coupled with
growth in patient care service revenue.  Revenues from patient care services
(associated with Company-owned offices) have a higher cost of revenue than the
Company's franchise business, which is generally associated with revenues from
royalty and other fees.  Two owned office locations were closed in the third
quarter of 1995 due to population demographics and financial trends which
limited the potential for long-term profitability.  The closures were part of
management's program to improve profitability of Company operations through a
reduced cost structure.  Management will continue to evaluate the profitability
of operations as it also evaluates strategies to increase revenues.

     Total operating expenses decreased 37.9 percent to $13,276,000 from
$21,372,000 in 1994.  Selling, general and administrative expenses decreased
11.6 percent as a result of increased personnel productivity and streamlining of
headquarters operations.  The Company's provision for doubtful accounts
decreased 13.0% or $246,000, with increased expense associated with increased
patient care revenue offset by decreased expense on the franchise business due
to improved receivable aging. Amortization of goodwill increased 10.8 percent
due to 1994 and 1995 acquisitions.  During 1994, the Company recognized
$6,536,000 in primarily non-cash charges relating to write-offs of notes
receivable and capitalized software development costs, additional reserves for a
note receivable, and severance.  If the effect of these 1994 charges is
excluded, total operating expenses decreased 10.5 percent in 1995.

     The effective combined federal and state income tax rate was 42.6 percent
and 23.1 percent (benefit) for 1995 and 1994, respectively.  The 1995 effective
tax rate is higher than the federal statutory tax rate of 34% due to state taxes
and to non-tax deductible expenses, primarily goodwill amortization.  Goodwill
amortization is a fixed expense, so the effective tax rate decreases as pre-tax
income increases.  The Company had net income of $2,988,000 in 1995 versus a net
loss of $1,978,000 in 1994.

LIQUIDITY AND CAPITAL RESOURCES

     As of December 31, 1996, the Company had cash and cash equivalents of
$1,223,000.  Working capital at that date was $21,458,000 versus $16,131,000 at
December 31, 1995.  The Company attempts to manage its cash balances to minimize
interest expense on its line of credit borrowing.  The Company has implemented
strict policies and procedures for controlling cash collections and
disbursements.

     As indicated in Note 4 to the Consolidated Financial Statements, in 1996
the Company entered into a $30 million revolving credit arrangement, subject to
certain financial covenants.  The credit availability was increased to $35
million in early 1997.  Management believes that cash flow from operations, in
conjunction with borrowing availability under its credit facility, will be
sufficient to meet the cash needs of the business for the immediate future, but
additional long-term financing may be needed to meet the Company's acquisition
plans.  There are no guarantees that such financing will be available or
available at an acceptable cost.

     There are currently various proposals under development to enact health
care reform on a national, state and local level.  It is not possible at this
time to predict the cash flow impact, if any,  which any such changes may have
on providers of home healthcare services and on the Option Care locations.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
Option Care, Inc.:


     We have audited the consolidated financial statements of Option Care, Inc.
and subsidiaries as listed in the accompanying index.  These consolidated
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Option Care,
Inc. and subsidiaries at December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1996 in conformity with generally accepted accounting
principles.

                      OPTION CARE, INC. AND SUBSIDIARIES

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                       DECEMBER 31, 1996, 1995 AND 1994


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (A)  DESCRIPTION OF BUSINESS

     Option Care, Inc. is a full service provider of home healthcare services.
The Company was incorporated in Delaware on July 9, 1991. The Company's
predecessor was incorporated in California in January 1984. As of December 31,
1996, 187 Option Care locations were operating in assigned territories in 37
states. Existing offices include 165 locations owned and operated by franchise
owners and 22 locations owned and operated by the Company.

     (B)  CONSOLIDATION

     The financial statements include Option Care, Inc. and its 50 percent or
more owned subsidiaries. The Company uses the cost method to account for
affiliates less than 20 percent owned. All significant intercompany accounts and
transactions have been eliminated in consolidation.

     (C)  INVENTORY

     Inventory, which consists of medical supplies, pharmaceuticals, and
displays and brochures is stated at cost, which approximates market, on a first-
in, first-out (FIFO) basis.

     (D)  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Equipment purchased under
capital leases is stated at the lower of the present value of minimum lease
payments at the beginning of the lease term or fair value at the inception of
the lease.

     Depreciation on equipment is calculated on the straight-line or double
declining balance method over the estimated useful lives of the assets (3-7
years for equipment). Leasehold improvements and equipment purchased under
capital leases are both amortized on the straight-line method over the shorter
of the lease term or estimated useful life of the asset.

     (E)  GOODWILL

     Goodwill, which represents the excess of fair market value over the cost of
net assets acquired, is amortized on a straight-line basis over 40 years.
Accumulated amortization was $592,000, $3,753,000, and $2,805,000 at December
31, 1996, 1995, and 1994, respectively.

     The Company assesses the recoverability of goodwill related to acquired
franchises by determining whether the amortization of such goodwill balance over
its remaining life can be recovered through undiscounted future operating cash
flows of the acquired operations. With regard to other goodwill, the Company

                                       31
<PAGE>
 
assesses impairment of this asset based on several factors, including probable
fair market value, cash flows, and the aggregate value of the franchise business
as a whole. See Note 9 of Notes to Consolidated Financial Statements.

     (F)  INCOME TAXES

     The Company files a consolidated federal income tax return with all of its
80 percent or more owned subsidiaries.

     (G)  PATIENT CARE SERVICES REVENUES

     A substantial portion of the Company's revenues are billed to third-party
payors. These revenues are recognized when service is provided, net of
contractual allowances. Payment from third-party payors is dependent upon the
specific benefits provided in the patient's policy. The Company adjusts
recognized revenues and the carrying value of patient receivables to provide for
the difference between billed charges and expected collections.

     (H)  ROYALTY FEES AND OTHER REVENUES

     Royalty fees and other revenues consist primarily of initial franchise fees
and royalty fees. Initial franchise fees are recognized when the franchise
training is completed and substantially all services have been provided. Royalty
fees are recognized when cash is reported as received by the franchises.
Franchise agreements provide for royalties to be paid to the Company based on
either 9 percent of gross cash receipts (subject to certain minimums and
discounts), or on a sliding scale ranging from 9 percent to 2 percent of gross
cash receipts depending on the levels of such receipts and other factors.

     (I)  NET INCOME (LOSS) PER COMMON SHARE

     Net income (loss) per common share is based upon average common and common
equivalent shares outstanding. Common equivalent shares include the dilutive
effect of stock options, if any.

     (J)  STATEMENT OF CASH FLOWS

     For purposes of the statement of cash flows, the Company considers all
highly liquid investments with an original maturity of three months or less to
be cash equivalents.

     (K)  USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period.  Actual results could differ from these
estimates.

     (L)  FINANCIAL INSTRUMENTS

     The fair value of the Company's financial instruments approximates their
carrying value.

(2)  BUSINESS COMBINATIONS

          At various dates during 1996, the Company purchased the assets of
franchises located in Bethel and Milford, OH, Everett, WA and Kennewick, WA as
well as all the outstanding stock of the franchise located in Oklahoma City, OK.
The Company also purchased the outstanding minority interest in the Bullhead
City, AZ location. The Company also purchased the assets of other healthcare
related businesses in Bethel and Milford, OH, Kirksville, MO, Jefferson City,
MO, Bullhead City, AZ, Grand Junction, CO, Little Rock, AR, Ontario, CA and
Houston, TX. The aggregate purchase price for these transactions, except for the
Oklahoma City acquisition was $7,220,000, of which $4,636,000 was paid in cash,
$1,305,000 in short-term obligations, $471,000 in long-term obligations and
$808,000 in forgiveness of accounts receivable. The purchase method of
accounting was used and $2,518,000 of goodwill was recorded.

          The Oklahoma City franchise, which was acquired through the issuance
of 500,000 shares of common stock, was treated as a pooling of interests, and
the accompanying financial statements have been restated by immaterial amounts
to reflect this transaction. The accompanying financial statements include the
results of operations of all other acquired businesses from the date of
acquisition. The unaudited pro-forma results of operations, affected by the
acquisitions accounted for as purchases as if they had occurred as of January 1,
1995, was as follows (in thousands, except per share data):

</TABLE>

     At various dates during 1995, the Company purchased the outstanding
minority interest in its Columbia, MO and Dallas, TX locations as well as the
assets of franchises located in Danbury, CT and Mansfield, OH.  The aggregate
purchase price for these transactions was $1,272,000, of which $441,000 was paid
in cash, $244,000 in short-term notes, $91,000 in long-term notes, and $496,000
in forgiveness of accounts receivable. The purchase method of accounting was
used and $452,000 of goodwill was recorded. The accompanying financial
statements include the results of operations of these acquired businesses from
the date of acquisition. Had the acquisitions taken place at the beginning of
1994, the effect on the Company's financial position and results of operations
would have been immaterial.

     All equipment purchased under capital leases is pledged as collateral.

     In December 1996, the Company entered into a $30,000,000 revolving credit
agreement ($15,000,000, $10,000,000 and $5,000,000 with PNC Bank, Harris Bank
and The Northern Trust Company, respectively), of which there were outstanding
borrowings of $11,900,000 at December 31, 1996. The agreement was amended in
early 1997 to increase the maximum available amount to $35,000,000 and to add
The First National Bank of Chicago to the lending syndicate. Borrowing under
this revolving credit facility will be used to satisfy the Company's working
capital requirements, as needed, and to fund acquisitions. The total outstanding
principal balance is payable in full on December 20, 1998. Outstanding
borrowings under this facility currently bear interest at the lenders' prime
rate plus 0.5 percent, which interest rate was 8.75 percent at December 31,
1996.

     The agreement provides that an annual commitment fee be paid by the Company
based on 0.375 percent average daily unused amount of the facility. The
agreement also requires the Company to maintain certain financial covenants
including, but not limited to: maximum leverage ratio, minimum interest coverage
ratio, minimum net worth and minimum capitalization. The agreement prohibits the
Company from declaring any cash dividends on its common stock. The revolving
credit facility is secured by all of the issued and outstanding common stock of
the Company and it's subsidiaries.

     On February 21, 1995, the Stock Option Committee of the Company's Board of
Directors repriced all outstanding employee stock options at the day's closing
price of $2.25.  All vesting schedules remained unchanged.

The 1996 Employee Stock Purchase Plan permits eligible employees to acquire
shares of the Company's common stock through payroll deductions not exceeding
15% of base wages, at a 15% discount from market price on the grant date.  There
were no shares related to the plan issued during 1996.

The Company applies Accounting Principles Board (APB) Opinion 25 and related
interpretations in accounting for its plans.  Accordingly, no compensation cost
has been recognized for its stock option plans.

Had compensation cost for the Company's stock-based compensations plans been
determined based on FASB Statement 123, the Company's net loss and loss per
share in 1996 and net income and earnings per share in 1995 would have been the
pro forma amounts indicated below:

</TABLE>

The fair value of options granted under the Company's stock option plan during
1995 and 1996 was estimated on the date of grant using the Black-Scholes option-
pricing model with the following assumptions used:  no dividend yield, expected
volatility of 30%, risk free interest rate of 6.5% and expected lives of 5
years.

(9)  REORGANIZATION EXPENSES AND OTHER CHARGES

     During 1996, the Company recorded a $24,164,000 non-cash charge related to
write-offs of various intangible assets.  These write downs primarily relate to
goodwill recorded through pushdown accounting for a change of control in 1990,
as well as goodwill related to prior year acquisitions.  The write-off resulted
from the Company's stated objective of purchasing existing franchises and from
evaluation of estimated future cash flows of acquired businesses.

     During 1994, the Company recognized $6,536,000 in primarily non-cash
charges relating to write-offs of notes receivable and capitalized software
development costs, additional reserves for a note receivable, and severance.

(10) COMMITMENTS AND CONTINGENCIES

     The Company was a defendant in a lawsuit filed in U.S. District Court,
Eastern District of California, by the former owners of two Option Care
franchises and other entities with which they are affiliated.  The plaintiffs
were pursuing claims for breach of contract, breach of the covenant of good
faith and fair dealing, breach of alleged fiduciary duties, promissory estoppel,
and violations of California franchise law.  On September 28, 1993, the U.S.
District Court, Eastern District of California, entered summary judgement for
the Company on all claims.  The plaintiffs appealed to the United States Court
of Appeals for the Ninth Circuit, which, on February 22, 1996, affirmed the
district court's 

                                       38
<PAGE>
 
decision. The plaintiffs then petitioned the Supreme Court of the United States
for a writ of certiorari. The Supreme Court of the United States denied the
petition for a writ of certiorari on October 7, 1996.

     The Company is a defendant in a lawsuit filed January 28, 1994 in U.S.
District Court, Clark County, Nevada, by one of the owners of the Las Vegas, NV,
franchise, which the Company managed through a subsidiary.  The plaintiff is
pursuing claims for breach of contract, breach of fiduciary duties, fraud,
negligent misrepresentation, and breach of implied covenant of good faith and
fair dealing.  The Company believes that the plaintiff's claims are without
merit, and intends to vigorously defend the lawsuit. The Company has filed a
motion to dismiss, which was granted on April 1, 1994 regarding the alleged
breach of fiduciary duty, breach of contract and fraud.  There has been no
subsequent pursuit of the remaining claims.  Should the plaintiff pursue these
claims in the future, the Company will vigorously contest such claims.

     On January 17, 1995, an action entitled Dennis H. Birenbaum v. Option Care,
Inc., Case No. 95-439, was filed with the District Court of Dallas County,
Texas. Plaintiff alleged breach of contract, promissory estoppel and negligent
misrepresentation concerning an alleged agreement for the sale and purchase of
Plaintiff's company.  In response, the Company produced evidence showing no
agreement was ever made. Dr. Birenbaum's lawsuit was dismissed and the Company
was awarded summary judgment by the Court.  Dr. Birenbaum has filed an appeal
which the Company is vigorously contesting.

     Despite the inherent uncertainties of litigation, management of the Company
at this time does not believe that the lawsuits will have a material adverse
impact on the financial condition of the Company.

     The Company may also be required, upon death or termination of employment,
to purchase stock of certain minority shareholders of subsidiaries.

                               OPTION CARE, INC.
                              FRANCHISE AGREEMENT


    This Franchise Agreement ("Agreement") between Option Care, Inc., a
California corporation, with its principal place of business at Bannockburn,
Illinois ("Franchisor") and Option Care Camilla, Inc., a Georgia corporation,
("Franchise Owner"), is made and entered into effective the date signed by
Franchisor on the signature page hereof (the "Effective Date").

                                   RECITALS

    A.   Franchisor has developed and owns a proprietary business method and
concept (the "System") relating to the operation of an outpatient health care
business that compounds pharmaceuticals, dispenses and administers
pharmaceuticals and physician prescribed biologicals, nutrients, medications and
solutions via parenteral and enteral routes in the home and in, subacute,
extended care, and other outpatient settings, furnishes clinical, pharmaceutical
and nursing services necessary to the provision of such therapies, sells related
products and supplies and sells or leases related equipment.  For purposes of
this Agreement, "parenteral" shall mean any administration route other than by
way of the intestines (e.g., without limitation, inhalation, transdermal and
intravenous).

    B.   The therapies under the System (the "Therapies") are set forth in the
Confidential Franchise Operations Manual (the "Manual") and include "Core
Therapies" and "Permitted Therapies", both as defined in the Manual.

    C.   The distinguishing characteristics of the System are set forth in the
Manual, which contains, without limitation, policies and procedures for the
Therapies; uniform standards, specifications and procedures for operation of the
business under the System, including the nature and manner of products and
services offered; procedures for quality improvement; training requirements;
group purchasing availability; and management, operational, and marketing
methods, techniques, materials, assistance and programs.

    D.   Pursuant to a license from Franchisor, each of Franchisor's franchise
owners does business under the name and mark "Option Care," and such other names
and marks as Franchisor may designate for use by each franchise owner under the
System (collectively, the "Proprietary Marks").

    E.   Franchise Owner wishes to obtain a franchise in order to operate a
business utilizing the System and the Proprietary Marks, as well as to receive
the Manual, the training and other assistance provided by Franchisor in
connection with the System pursuant to this Agreement.
<PAGE>
 
    F.   The business to be conducted by Franchise Owner pursuant to and under
the license granted by this Agreement is sometimes referred to herein as the
"Franchised Business".

    G.   Franchise Owner understands and acknowledges the importance of
Franchisor's high and uniform standards of quality and service and the necessity
of operating the Franchised Business in conformity with Franchisor's standards
and specifications, including the Manual.

    H.   Franchise Owner acknowledges that it has received a copy of this
Agreement, and the related exhibits and agreements, at least five (5) business
days prior to the date on which this Agreement was executed by Franchise Owner.
Franchise Owner further acknowledges that it has received the disclosure
document required by the Trade Regulation Rule of the Federal Trade Commission,
entitled "Offering Circular for Prospective Franchise Owners," at least ten (10)
business days prior to the date on which this Agreement was executed.

    NOW, THEREFORE, Franchisor and Franchise Owner, in consideration of the
undertakings and commitments of each party to the other party set forth herein
and the recitals set forth above, which are  incorporated into and made a part
of this Agreement, mutually agree as follows:

1.  GRANT

and the Proprietary Marks.

    1.2  Deliveries on Grant.  Contemporaneous with Franchise Owner delivering
         -------------------                                                  
this executed Agreement to Franchisor, it shall also deliver to Franchisor the
following:

         (a) A check in the amount specified in Section 5.1 hereof;

         (b) A copy of the fronts and backs of its issued stock certificates,

         (d) A fully executed "Guarantee".

<PAGE>
 
2.  TERRITORY

    2.1  Territory Defined.  Franchisor hereby grants to Franchise Owner the
         -----------------                                                  
right to operate the Franchised Business during the term of this Agreement
within the defined area (the "Territory") described on attached Exhibit A, which
Exhibit is incorporated herein by reference thereto.  Franchise Owner
acknowledges and agrees that this Agreement affords it no right, title or
interest in or to additional franchises or any right to acquire additional
franchises or territory, nor does it obligate Franchisor in any way to grant or
sell any additional franchises or territory to Franchise Owner.

    2.2  Patient Freedom of Choice.  Notwithstanding the grant of the Territory,
         -------------------------                                              
Franchise Owner acknowledges and agrees that (i) patients residing within the
Territory are entitled to the freedom to choose their health care provider and
may seek health care services of the type provided by Franchise Owner from
others, including another franchise owner of Franchisor; and (ii) health care
referral sources may refer patients residing within the Territory to health care
providers of their choosing, including to another franchise owner of Franchisor.

    2.3  Marketing Efforts in Territory.  Franchise Owner agrees to devote its
         ------------------------------                                       
best efforts to serving patients that reside within the Territory.  Except as
otherwise permitted herein or as approved in advance and in writing by
Franchisor, Franchise Owner's marketing and promotional activities shall be
directed only toward obtaining patients who reside within the Territory.
Franchise Owner acknowledges and agrees that Franchisor, as part of its business
strategy, may advertise or market on behalf of the System in the Territory and
may maintain itself, or through its affiliates, a presence in the Territory for
the purpose of providing a managed care program offering services of the type
provided by the Franchised Business. Franchise Owner agrees to abide by
Franchisor's then current policies on marketing outside of the Territory, and on
cooperating with neighboring Option Care franchisees, as the same may be set
forth from time to time in the Manual.

    2.4  Presence in Territory.  Franchise Owner shall maintain such manner and
         ---------------------                                                 
degree of presence in the Territory as from time to time required by the Manual.
Such presence requires Franchise Owner to maintain an I.V. pharmacy within the
Territory unless Franchise Owner has the prior written approval of Franchisor to
utilize the I.V. pharmacy services of another Option Care Franchise and utilize
such services on the basis approved by Franchisor. Even if Franchise Owner is
not required to itself maintain an I.V. pharmacy in the Territory, it must
maintain a physical presence in the Territory consistent with Franchisor's
requirements therefor as then set forth in the current Manual. The initial

term of this Agreement, and for so long thereafter as Franchise Owner realizes
Gross Receipts (as defined in Section 5.7), Franchise Owner agrees to pay to
Franchisor a continuing monthly royalty fee (the "Continuing Monthly Royalty
Fee") in the amount equal to nine percent (9%) of the first $1,000,000 of Gross
Receipts during each calendar year, seven percent (7%) of the next $1,000,000 of
Gross Receipts during each calendar year, and five percent (5%) of all Gross
Receipts in excess of $2,000,000 during each calendar year.  The dollar amounts

    10.2 Submit Marketing Plans.  Franchise Owner agrees to submit to
         ----------------------

(except with respect to prices to be charged), samples of all marketing and
promotional plans and materials that Franchise Owner desires to use and which
have not been prepared or previously approved by Franchisor within the prior
twelve month period.  If written disapproval thereof is not received by
Franchise Owner from Franchisor within fifteen (15) days of receipt by
Franchisor of such samples or materials, Franchisor shall be deemed to have
given the required approval. Franchisor reserves the right to communicate, in
whole or in part, marketing and promotional plans and materials which it
receives from the Franchise Owner to other franchise owners for their use, or to
use the same in any marketing and promotion by Franchisor.

    10.3 National Fund. Franchise Owner's monthly contribution to the National
         -------------                                                        
Fund may be increased to exceed one and one-half percent (1.5%) of Gross
Receipts, and/or the maximum annual contribution may exceed $10,000, if two-
thirds (2/3) of all franchise owners who are obligated to contribute to the
National Fund vote for an increase in the contribution to the National Fund.  In
connection with any vote to increase contributions to the National Fund,
Franchise Owner shall have one vote for each franchise agreement under which
Franchise Owner is required to become a member of the National Fund.  The
National Fund shall be maintained and administered by Franchisor or its
designee, as follows:

         10.3.1  The National Fund, all contributions thereto, and any earnings
thereon shall be used exclusively to meet any and all costs of preparing,
offering, distributing, obtaining, conducting and administering marketing, and
educational  activities, and providing training opportunities for Option Care
franchisees;

         10.3.2  Franchisor shall direct all activities of the National Fund
with sole discretion over the concepts, materials, and media used and the
placement and allocation thereof.  Franchise Owner agrees and acknowledges that
Franchisor undertakes no obligation in administering the National Fund to make
expenditures for Franchise Owner which are equivalent or proportionate to
Franchise Owner's contribution or to insure that any particular franchise owner
benefits directly or pro rata from expenditures by the National Fund;

         10.3.3  Franchise Owner agrees to contribute to the National Fund by
separate check made payable to the National Fund.  All sums paid by Franchise
Owner to the National Fund shall be maintained in an account separate from the
other monies of Franchisor and shall not be used to defray any of Franchisor's
expenses, except for such reasonable administrative costs and overhead, if any,
as Franchisor may incur in activities reasonably related to the conduct of
activities under and maintenance and administration of the National Fund.  The
National Fund and its earnings shall not otherwise inure to the benefit of
Franchisor. Franchisor shall maintain separate bookkeeping accounts for the
National Fund, which shall 

                                       18
<PAGE>
 
not be an asset of Franchisor. A statement of the operations of the National
Fund as shown on the books of the National Fund shall be prepared annually and
shall be made available to Franchise Owner;

         10.3.4  It is intended that contributions to, and earnings of, the
National Fund shall not be taxable income to Franchisor.  Toward this end, it is
anticipated that all contributions to and earnings of the National Fund will be
expended for marketing, educational training and promotional purposes during the
taxable year of receipt.  If, however, excess amounts remain in the National
Fund at the end of a taxable year, all expenditures in the following taxable
year(s) shall be made first out of accumulated earnings from previous years,
next out of earnings in the current year and finally from contributions; and

         10.3.5  Although the National Fund is intended to be of perpetual
duration, Franchisor maintains the right to terminate the National Fund.  The
National Fund shall not be terminated, however, until all monies in the National
Fund have been expended in accordance with the provisions of this Section  5.4
or returned to contributors on the basis of their respective contributions.

limited to income tax returns, in the form and manner, and at the times and

books and records of the Franchised Business.  If an inspection or audit 

                                       19
<PAGE>
 
should reveal that any Gross Receipts have been understated in any report to
Franchisor, then Franchise Owner shall immediately pay to Franchisor, upon
demand, all royalties due on the amount understated, in addition to interest
from the date such royalties were due until paid, at the rate which is two
percent (2%) per month or the maximum rate permitted by law, whichever is less.
If an inspection or audit discloses an understatement of five percent (5%) or
more in any report of Gross Receipts, Franchise Owner shall, in addition,
reimburse Franchisor for any and all costs and expenses connected with the
inspection or audit (including, without limitation, travel, lodging and wage

    12.3 No Limitation.  Franchise Owner's obligations to obtain and maintain
         -------------                                                       
the required policy or policies in the amounts specified shall not be limited in
any way by reason of any insurance which may be maintained by Franchisor, nor
shall Franchise Owner's performance of that obligation relieve it of liability
under the indemnity provisions set forth in Section 20 of this Agreement.

    12.4 Evidence of Insurance.  At least thirty (30) days prior to the time any
         ---------------------                                                  
insurance is first required to be carried by Franchise Owner, and thereafter
upon renewal or replacement of any such policy, Franchise Owner shall deliver to
Franchisor Certificates of Insurance evidencing the proper coverage with limits
not less than those required by this Agreement. All Certificates shall expressly
provide that no less than thirty (30) days' prior written notice shall be given
to Franchisor in the event of material alteration to, or cancellation or lapse
of, the coverages evidenced by such Certificates.

    12.5 Franchisor's Right to Procure.  Should Franchise Owner, for any reason,
         -----------------------------                                          
fail to procure or maintain the insurance required by this Agreement, Franchisor
shall have the right and authority (without, however, any obligation to do so)
to immediately procure such insurance and to charge the same to Franchise Owner.
The foregoing remedies shall be in addition to any other remedies Franchisor may
have.

    12.6 Waiver of Subrogation.  To the maximum extent permitted by insurance
         ---------------------                                               
policies which may be owned by Franchisor and Franchise Owner, Franchise Owner
and Franchisor, for the benefit of each other, waive any and all rights of
subrogation which might otherwise exist.

13. TRANSFER OF INTEREST

    13.1 Transfer by Franchise Owner.
         --------------------------- 

         13.1.1  Franchise Owner understands and acknowledges that the rights
and duties set forth in this Agreement are personal to Franchise Owner, and that
Franchisor has granted this franchise in reliance on Franchise Owner's business
skill, financial capacity, personal character and professional reputation.
Accordingly:

                                       21
<PAGE>
 
                    13.1.1.1  Neither Franchise Owner nor any individual,
partnership, corporation or other legal entity which directly or indirectly owns
any interest in this Franchise (as defined below) shall sell, assign, transfer,
convey, give away, pledge, mortgage or otherwise encumber (all of which shall be
referred to as a "Transfer" for purposes of this Section only) any direct or
indirect interest in Franchise Owner, this Agreement, the Franchised Business or
all or a substantial portion of the stock or assets of the Franchise Owner or
the Franchised Business, including any portion of the Territory (all of which
shall be referred to as the "Franchise" for purposes of this Section 13 only)
without the prior written consent of Franchisor;

                    13.1.1.2  Franchisor's prior written consent shall not be
required for a transfer of less than a five percent interest in a publicly-held
corporation; and

                    13.1.1.3  Any purported assignment or transfer, by operation
of law or otherwise, not having the prior written consent of Franchisor shall be
null and void and shall constitute a material breach of this Agreement, for
which Franchisor may terminate without opportunity to cure pursuant to Section
14.1.6 of this Agreement;

         13.1.2  Franchisor shall not unreasonably withhold its consent to a
Transfer of an interest in the Franchise, provided that Franchisor may require
any or all of the following of the Franchise Owner and its beneficial owners
(collectively referred to as "Transferor" for purposes of this Section) and the
transferee and its beneficial owners (collectively referred to as "Transferee"
for purposes of this Section) as conditions of its approval:

                    13.1.2.1  Each Transferee shall execute the form of personal
guarantee attached to this Agreement;

                    13.1.2.2  All of Transferor's accrued monetary obligations
and other outstanding obligations to Franchisor and its affiliates shall have
been satisfied;

                    13.1.2.3  Transferor is not in default of any provision of
this Agreement, any amendment to this Agreement, or any other agreement between
Transferor and Franchisor or its affiliates;
 
                    13.1.2.4  Transferor shall have executed a general release
in a form satisfactory to Franchisor of any and all claims against Franchisor
and its affiliates and their respective shareholders, partners, directors,
officers, employees and agents, in their corporate and individual capacities, to
the fullest extent permitted by law;

                    13.1.2.5  Each Transferee shall enter into a written
assignment in a form satisfactory to Franchisor, assuming and agreeing to
discharge all of Franchise Owner's obligations under this Agreement;

                                       22
<PAGE>
 
                    13.1.2.6  Each Transferee shall demonstrate to Franchisor's
satisfaction that such Transferee meets Franchisor's professional, educational,
managerial, financial and business standards, and possesses a good moral
character;

                    13.1.2.7  Any person who is to be substituted as Manager of
the Franchised Business shall have been approved by Franchisor and, unless
waived in writing by Franchisor, shall successfully complete the next available
franchise training and complete the Install Program training course then in
effect;

                    13.1.2.8  Transferor shall pay to Franchisor a non-
refundable transfer fee to cover Franchisor's legal, accounting, record keeping
and other costs related to the Transfer in an amount not to exceed fifty percent
(50%) of the initial fee that then would be charged to new franchise owners
under the System for a comparable territory;

                    13.1.2.9  Transferor shall agree to remain liable for all of
the obligations to Franchisor in connection with the Franchised Business prior
to the effective date of the Transfer;

                    13.1.2.10 In the event that the proposed Transfer is to a
corporation formed by Franchise Owner for the convenience of ownership,
Transferor shall be the owner of all the voting stock of the corporation; and

                    13.1.2.11 In the event a Transfer, alone or together with
other Transfers, would have the effect of transferring a controlling interest in
the Franchise, the Transferee shall execute, for a term ending on the expiration
date of this Agreement, the standard form of franchise agreement then offered to
new franchise owners, which franchise agreement may have terms different from
the terms of this Agreement; provided, however, in lieu of any initial fee, the
Transferor shall pay the transfer fee described in Section 13.1.2.8 above, and
the royalty fee, the National Fund contribution limitation, and the Territory
shall remain the same. The Transferee shall also execute such other ancillary
agreements as Franchisor may require for the Franchised Business.

    13.2 Offerings by Franchise Owner.  Securities or partnership interests in
         ----------------------------                                         
Franchise Owner may be sold, by public or private offering or otherwise, only
with the prior written consent of Franchisor (whether or not Franchisor's
consent is required under Section 13.1 hereof), which consent shall not be
unreasonably withheld.  All materials required for such offering by federal or
state law shall be submitted to Franchisor for review prior to being filed with
any government agency; and any materials to be used in any exempt offering shall
be submitted to Franchisor for review prior to their use.  Franchise Owner shall
provide all such materials to Franchisor at least thirty (30) days prior to the
commencement of any offering. No Franchise Owner offering shall imply (by use of
the Proprietary Marks or otherwise) that Franchisor is participating as an
underwriter, issuer or offeror of securities; and Franchisor's review of any
offering shall be limited solely to the subject of the relationship between

                                       23
<PAGE>
 
Franchise Owner and Franchisor.  Franchise Owner and the other participants  in
the offering must fully indemnify Franchisor in connection with the offering.
For each proposed offering, Franchise Owner shall pay to Franchisor a non-
refundable fee, not to exceed fifty percent (50%) of the initial fee that then
would be charged to new franchise owners under the System for a comparable
territory, to reimburse Franchisor for its reasonable costs and expenses
associated with reviewing the proposed offering.

    13.3 Right of First Refusal.
         ---------------------- 

         13.3.1  Any party holding any interest in the Franchise who desires to
accept any offer from a third party to purchase such interest shall notify
Franchisor in writing of the offer, and shall provide such information and
documentation relating to the offer as Franchisor may require.

         13.3.2  Except for a Transfer among the original owners who were
granted the franchise hereunder or a Transfer from an original owner to that
owner's spouse or child(ren), Franchisor shall have the right and option,
exercisable within sixty (60) days after receipt of written notification and
receipt of any required information or documentation, to send written notice to
the seller that Franchisor intends to purchase the seller's interest on the same
terms and conditions contained in a bona fide offer from the third party, or the
                                    ---- ----                                   
cash equivalent.  In the event that Franchisor elects to purchase the seller's
interest, closing on such purchase must occur within sixty (60) days from the
date of notice to the seller of the election to purchase by Franchisor.  In the
event that Franchisor does not elect to purchase the sellers' interest, closing
on such purchase shall occur within ninety (90) days after the expiration of
Franchisor's right to purchase.  Failure to close the sale within said period or
any material change in the terms of the offer prior to closing shall constitute
a new offer subject to the same rights of first refusal by Franchisor described
in this Section 13.3.

         13.3.3  Failure of Franchisor to exercise the option afforded by this
Section 13.3 shall not constitute a waiver of any other provision of this
Agreement, including all the requirements of this Section 13, with respect to a
proposed Transfer.

    13.4 Transfer Upon Death or Mental Incapacity.  Upon the death or finding
         ----------------------------------------                            
by a court of mental incapacity of any person with an interest in the Franchise,
the executor, administrator or personal representative of such person shall
transfer within six (6) months after such death or mental incapacity the
deceased or incompetent owner's interest to a third party approved by
Franchisor.  Such transfers, including transfers by devise or inheritance, shall
be subject to the same conditions as any Transfer.  However, in the case of
transfer by devise or inheritance, if the heirs or beneficiaries of any such
person are not approved by Franchisor, the personal representative of the
deceased shall have a reasonable time to dispose of the deceased's interest,
which disposition shall be subject to all the terms and conditions for Transfers
contained in this Agreement.  If the interest is not disposed of within six (6)
months, Franchisor may terminate this Agreement.

                                       24
<PAGE>
 
    13.5 Non-Waiver of Claims.  Franchisor's consent to a Transfer shall not
         --------------------                                               
constitute a waiver of any claims it may have against the Transferor, nor shall
it be deemed a waiver of Franchisor's right to demand exact compliance with any
of the terms of this Agreement by the Transferee.

    13.6 Transfer by Franchisor.  Franchisor shall have the right to transfer
         ----------------------                                              
or assign all or any part of its rights or obligations herein to any person or
legal entity.

forfeits the right to transact business in the Territory.  However, if such
abandonment results from the governmental exercise of the power of eminent
domain or is due to fire, flood, earthquake or other similar cause beyond

the suspension or revocation of Franchise Owner's pharmacy permit or any nursing
license Franchise Owner may have obtained;

         14.1.4  Franchise Owner fails, for a period of ten (10) days after
notification of noncompliance from any applicable agency, to comply with any

provided for under this Agreement;

Section 14.1 or in material default pursuant to any other agreement with
Franchisor or any affiliate of Franchisor, or, after curing any default
following notice pursuant to Section 14.3, commits the same default, whether or
not cured after notice;

         14.1.11 Franchise Owner fails to comply with the in-term covenants in
Section 16 or fails to obtain execution of the covenants required under Section
9 or Section 16;

Manual or other Confidential Information contrary to the terms of this
Agreement;

         14.1.13 Franchise Owner or any beneficial owner makes a material
misrepresentation or omits to disclose material information to Franchisor in
connection with the application to Franchisor for this Franchise Agreement;

         14.1.14 Franchisor determines that continued operation of the
Franchised Business poses a material threat to public health or safety; or

required accreditation.

in default under this 

                                       26
<PAGE>
 
Agreement, and this Agreement shall automatically terminate without notice to
Franchise Owner:

this Agreement only by giving written notice of termination to Franchise Owner
stating the nature of the default or breach at least thirty (30) days prior to
the effective date of termination or such longer period as applicable law may
require (the "Cure Period"); provided, however, that Franchise Owner may avoid
termination by immediately initiating a remedy to cure such default or breach

         ------------------------                                           
agree that the existence of any claims they may have against Franchisor, whether
or not arising from this Agreement, shall not constitute a defense to the
enforcement by Franchisor of the covenants in this Section 16.  Franchise Owner
and its Owners jointly and severally agree to pay all costs and expenses
(including reasonable attorneys' fees) incurred by Franchisor in connection with
the enforcement of this Section 16.

    16.5 Irreparable Injury.  Franchise Owner  and its Owners acknowledge that
         ------------------                                                   
Franchise Owner's violation of the terms of this Section 16 would result in
irreparable injury to Franchisor for which no adequate remedy at law may be
available, and Franchise Owner and its Owners accordingly agree that Franchisor
may seek an injunction prohibiting any conduct by Franchise Owner and its Owners
in violation of the terms of this Section 16.

obtain execution of covenants similar to those set forth in this Section 16,
including covenants that are operative upon the termination of a person's
relationship with Franchise Owner, from supervisory personnel, officers and
directors, and other persons reasonably determined by Franchisor to be in a
position to use information gained from their association with Franchise Owner
to compete with the Franchise Owner and the System.  Every covenant required by
this Section 16.6 shall be in a form satisfactory to Franchisor, including,
without limitation, specific identification of Franchisor as a third party
beneficiary of such covenants with the independent right to enforce them.

Agreement, unless the tax is credited against income tax otherwise payable by
Franchisor.

    18.2 In the event of any bona fide dispute as to Franchise Owner's liability
for taxes, accounts, or other indebtedness, Franchise Owner may contest the
validity or the amount of the tax, account or indebtedness in accordance with
procedures of the taxing authority or applicable law; however, in no event shall
Franchise Owner permit a tax sale or seizure by levy of execution or similar
writ or warrant, or attachment by a creditor, to occur against the Franchised
Business, any office, any improvements to any office, or any other asset of
Franchise Owner.

    18.3 Franchise Owner shall notify Franchisor in writing within five (5) days

governmental instrumentality, which may adversely affect the operation or
financial condition of the Franchised Business.

19. INDEPENDENT CONTRACTOR; AUTHORITY

    It is understood and agreed by the parties hereto that this Agreement does
not create a fiduciary relationship between them; that Franchise Owner shall be
an independent contractor and shall hold itself out to the public as an
independent contractor including in such manner as Franchisor may reasonably
specify; and that nothing in this Agreement is intended to constitute either
party an agent, legal representative, subsidiary, joint venturer, partner,
employee or servant of the other for any purpose whatsoever.

    It is understood and agreed that nothing in this Agreement authorizes
Franchise Owner to make any contract, agreement, warranty or representation on
Franchisor's behalf, or to incur any debt or other obligation in Franchisor's
name, and that Franchisor shall in no event assume liability for, or be deemed
liable under this Agreement as a result of, any such action or by reason of any
act or omission of Franchise Owner in its conduct of the Franchised Business, or
any claim or judgment arising therefrom against Franchisor.

<PAGE>
 
    20.1 Franchise Owner assumes sole responsibility for losses arising out of
the operation of the Franchised Business, and the acts or omissions of Franchise
Owner and its agents, servants and contractors.  Franchise Owner shall
indemnify, defend and hold Franchisor and its shareholders, partners, directors,
officers, employees and agents harmless against and to reimburse them for all

Franchisor, Franchise Owner shall make a timely written request to Franchisor,
and such approval or consent shall be obtained in writing signed by the
President or any Vice President of Franchisor.  No other communication from any
officer, employee or agent of Franchisor, whether oral or in writing, shall
constitute a valid approval or consent of Franchisor pursuant to this Section
21.

    Franchisor makes no warranties or guarantees upon which Franchise Owner may
rely, and assumes no liability or obligation to Franchise Owner, by providing
any waiver, approval, consent or suggestion to Franchise Owner in connection
with this Agreement, or by reason of any neglect, delay, or denial of any
request therefor.

    No delay, waiver, omission or forbearance on the part of Franchisor to
exercise any right, option, duty or power arising out of any breach or default
by Franchise Owner under any of the terms, provisions, covenants or conditions
hereof, shall constitute a waiver by Franchisor to enforce any such right,
option, duty or power as against Franchise Owner, or as to any subsequent breach
or default by Franchise Owner.

Agreement shall be binding on either party unless mutually agreed to by the
parties and executed by their authorized officers or agents in writing.

24. SEVERABILITY AND CONSTRUCTION

    Except as expressly provided to the contrary in this Agreement, nothing in
this Agreement is intended, nor shall be deemed, to confer any rights or
remedies under or by reason of this Agreement upon any person or legal entity
other than Franchise Owner, Franchisor, Franchisor's officers, directors and
employees, and such of Franchise Owner's and Franchisor's respective successors
and assigns as may be contemplated and permitted by Section 13 hereof.

    Franchise Owner agrees that each promise or covenant of this Agreement that
may result from striking any portion or portions which a court may hold to be
unreasonable and unenforceable in a final decision to which Franchisor is a
party, or from reducing the scope of any promise or covenant to the extent
required to comply with such a court order, is separately enforceable to the
maximum extent permitted by law.

    All captions in this Agreement are intended solely for the convenience of
the parties, and none shall be deemed to affect the meaning or construction of
any provision hereof.

    All references herein to the masculine, neuter, singular or plural shall be
construed to include the masculine, feminine, neuter, singular or plural, where
applicable; and all acknowledgments, promises, covenants, agreements and
obligations herein made or undertaken by Franchise Owner shall be deemed jointly
and severally undertaken by all those executing this Agreement on behalf of
Franchise Owner.

    This Agreement may be executed in several counterparts and each copy so
executed shall be deemed one and the same document.

25. APPLICABLE LAW

    This Agreement takes effect upon its acceptance and execution by Franchisor
in Illinois, and shall be interpreted and construed under the laws of Illinois,
which laws shall prevail in the event of any conflict of law; provided, however,
that if any of the provisions of this Agreement would not be enforceable under
the laws of Illinois, then such provisions shall be interpreted and construed
under the laws of the state in which the Franchised Business is located.

    The parties agree that any action brought by either party against the other
in any court, whether federal or state, shall be brought within the State of
Illinois in the Cook County judicial district and do hereby waive all questions
of personal jurisdiction or venue for the purpose of carrying out this
provision.

                                       35
<PAGE>
 
         No right or remedy conferred upon or reserved to Franchisor or
Franchise Owner by this Agreement is intended to be, nor shall be deemed,
exclusive of any other right or remedy herein or permitted by law or equity, but
each shall be cumulative of every other right or remedy.

         Nothing herein contained shall bar Franchisor's right to obtain
injunctive relief against threatened conduct that will cause it loss or damages,
under the usual equity rules, including the applicable rules for obtaining
restraining orders and preliminary injunctions.

26. ACKNOWLEDGMENTS

                                     LEASE


     THIS LEASE, made as of this 23rd day of October, 1996, between LaSALLE

Inc., a Delaware corporation (hereinafter known as "Tenant");

                                  WITNESSETH:

     THAT Landlord hereby leases to Tenant, and Tenant accepts the demised
premises consisting of approximately 13,655 rentable square feet of space on the
second floor and not more than 800 square feet of storage space on the lower
level in the building (hereinafter known as "Building") known as the 100
Corporate North Building, Bannockburn, Illinois, all as described in the floor
plans attached hereto as (i) Exhibits "A-1" and "A-2", for the term of five (5)
years and six (6) months unless sooner terminated as provided herein, commencing
November 1, 1996 ("Commencement Date") and ending May 31, 2002 ("Expiration
Date") and (ii) approximately 5,190 rentable square feet as described on Exhibit
"B," commencing June 1, 1997 ("Expansion Space Commencement Date"), subject to
Section 5 hereof, to be occupied and used by the Tenant for general offices and
no other purpose, subject to the agreements herein contained (the space
described in Exhibits "A-1" and "A-2" and Exhibit "B" shall hereinafter be
referred to collectively as the "Premises." Exhibits "A-1" and "A-2" shall be
referred to separately as the "Initial Space" and Exhibit "B," the "Expansion
Space").

     IN CONSIDERATION THEREOF, THE PARTIES COVENANT AND AGREE:

     1.   RENT.  The Tenant shall pay as Net Base Rent for the Initial Space to
Property & Facility Management Group LLC, or to such other person or at such
other place as Landlord may direct in writing beginning on the Commencement
Date, an Annual Base Rent of $187,756.20 payable in equal monthly installments
of $15,646.35 in advance on or before the first day of each month of the term
and 
<PAGE>
 
thereafter as set forth in the rent schedule attached as Exhibit "C" and after
the Expansion Space Commencement Date, as set forth in Exhibit "D," rent shall
be paid without any set-off or deduction whatsoever. Unpaid rent shall bear
interest at the rate set forth in Section 27(f), commencing on the eleventh
(11th) day after the date due until paid. Time is of the essence of this Lease.
Tenant agrees to do and perform each and every covenant, agreement and
obligation to be performed by Tenant hereunder.

     2.   RENT ADJUSTMENT.  Tenant shall pay additional annual rent for Taxes
and Expenses in accordance with the provisions of this Section 2. Such
additional rent is hereinafter referred to as "Rent Adjustment."

          (a)  Intentionally deleted.

          (b)  (1)  Tenant shall pay to the Landlord, as additional rent, an
amount equal to that proportion of the amount of Taxes (as defined in Section
2(b)(2) attributable to any calendar year of the Lease term as the rentable area
of the premises bears to the rentable area of the Building (such proportion
hereinafter being called "Tenant's Proportion"). The amount of Taxes
attributable to a calendar year shall be the amount payable during any such
year, even though the assessment for such Taxes may be for a different year.

               (2)  The term "Taxes" shall mean real estate taxes, assessments,
sewer rents, sewer rates and sewer charges, transit taxes, taxes based upon the
receipt of rent, and any other federal, state or local governmental charge,
general, special ordinary or extraordinary which may now or hereafter be levied
or assessed against the property upon which the Building stands and upon the
Building, hereinafter collectively known as "Real Property." In case of special
Taxes or assessments which may be payable in installments, only the amount of
each installment paid during a calendar year shall be included in Taxes for that
year. Taxes shall also include any personal property taxes (attributable to the
year in which paid) imposed upon the furniture, fixtures, machinery, equipment,
apparatus, systems and appurtenances used in connection with said Real Property
for the operation thereof and all fees and costs (including attorneys' fees)
incurred by Landlord in seeking to obtain a reduction of, or a limit on the
increase in, 

                                       2
<PAGE>
 
any Taxes, regardless of whether any reduction or limitation is obtained.

                    Notwithstanding the foregoing, there shall be excluded from
Taxes: income taxes, franchise, capital stock and state and federal inheritance
taxes, all interest and penalties on such Taxes (to the extent such interest and
penalties arise out of Landlords failure to pay the Taxes and not as a result of
Tenants failure to pay Taxes), other taxes imposed upon or measured by the
Landlords income or profits, unless the same shall be imposed in lieu of real
estate taxes and other ad valorem taxes.

               (3)  If the tax year for real estate taxes shall be changed by
the applicable governmental authority resulting in the payment by the Landlord
in one calendar year of Taxes which relate to more than one calendar year, then
notwithstanding anything to the contrary contained in this Lease, for purposes
of determining the Rent Adjustment for such calendar year, such amount of taxes
shall be adjusted to an amount which is equivalent to a one-year payment of
Taxes.

          (c)  Tenant shall pay to the Landlord as additional rent Tenant's
Proportion of the amount of Expenses (as herein defined) attributable to any
calendar year of the Lease. For the purposes of this Section 2(c), the term
"Expenses" shall mean and include all expenses paid or incurred by the Landlord
for managing, maintaining, operating, insuring, replacing and repairing the Real
Property, appurtenances and personal property used in conjunction therewith
(hereinafter referred to as "Project"). Expenses shall not include: (1) costs of
alterations of the premises of tenants of the Building; (2) expenses incurred by
Landlord for repairs or other work occasioned by fire, windstorm, or other
insurable casualty or condemnation, which expenses are recovered by insurance
proceeds; (3) expenses incurred by Landlord to lease space to new tenants or to
retain existing tenants, including, without limitation, leasing commissions,
advertising and promotional expenditures; (4) expenses incurred by Landlord to
resolve disputes, enforce or negotiate lease terms with prospective or existing
tenants or in connection with any financing, sale or syndication of the
Property; (5) Interest, principal, points and fees, amortization or other costs
associated with any debt and rent payable under any lease to which this Lease is
subject and all costs and expenses associated with any such debt or lease and
any ground lease rent, irrespective of whether this Lease is subject or

                                       3
<PAGE>
 
subordinate thereto; (6) expenses for the replacement of any item reimbursed to
Landlord under warranty; (7) any penalty or fine incurred by Landlord due to
Landlord's violation of any federal, state, or local law or regulation and any
interest or penalties due for late payment by Landlord; (8) cost of correcting
any latent defects or original design defects in the Building construction
materials or equipment, but only to the extent such costs relate to the
structural systems of the Building; (9) expenses for any item or service not
made available by Landlord to all tenants of the Building which Tenant pays
directly to a third party or, if provided by Landlord, Tenant separately
reimburses Landlord and expenses incurred by Landlord due to special request of
tenants or third parties to the extent the same are reimbursable or reimbursed
from any other tenants or third parties; (10) fees paid to affiliates of

shall be remediated at the sole cost of Tenant. Expenses shall include (i) the
cost of any capital expenditures incurred in connection with the operation or
maintenance of the Project, as reasonably amortized by Landlord; such capital
expenditures include without limitation the cost of any capital improvements
installed for the purposes of reducing or controlling Expenses; and (ii) the
cost of any capital improvements which are necessary to keep the Project in
compliance with all governmental rules, regulations, ordinances and statutes. If
the building is not fully rented during all or a portion of any year subsequent
to the Base Year, then Landlord may elect to make an appropriate adjustment of
the Expenses for such year employing sound accounting and management principles,
to determine the amount of Expenses that would have been paid or incurred by the
Landlord had the Building been fully occupied; and the amount so determined
shall be the amount of Expenses attributable to such year. If any Project
expense, though paid in one year, relates to more than one calendar year, at the
option of Landlord such expenses may be proportionately allocated among such
related calendar years.

                    (i)   a lump sum due for the number of months of the then
calendar year preceding and including the month of the date of the Landlord's

                    (ii)  the amount for the period of the then calendar year
following the date of the Landlord's Statement to be paid in equal monthly

following the furnishing by the Landlord to the Tenant of such statement. Unless
the Tenant shall take written exception to any item within sixty (60) days after

as final and accepted by the Tenant. Any amount due to the Landlord as shown on
Landlord's Statement, whether or not written exception is taken thereto, shall
be paid by the Tenant within thirty (30) days after the Landlord shall have
submitted the Landlord's Statement, without prejudice to any such written

to one of three independent Certified Public Accountants ("CPA") to be chosen by
Tenant from a list of three CPAs selected by Landlord. The three CPAs chosen by
Landlord and submitted to Tenant shall be selected from the "big six." The
decision of the selected CPA shall be final and binding on Landlord and Tenant.
If Tenants review shall disclose an inaccuracy in favor of Landlord greater than
a 5% error with respect to the amount due from Tenant for the period of the
Landlord's Statement, then Landlord shall pay the reasonable cost of the CPA;

Proportion the rentable square feet of the Building shall be 98,680.

thereof. The electricity used during the performance of janitor service, the
making of alterations or repairs in the demised premises, and for the operation

shall make no alterations or additions to the electric equipment and/or
appliances without the prior written consent of the Landlord in each instance.
Tenant also agrees to purchase from the Landlord or its agents all lamps, bulbs,
ballast and starters used in the demised premises after the installation thereof
so long as Landlord replaces all bulbs within a reasonable period of time.
Tenant covenants and agrees that at all times its use of electric current shall
never exceed the capacity of the feeders to the Building or the risers or wiring
installation.

be free from interruptions caused by war, insurrection, civil commotion, riots,
acts of God or the enemy, governmental action, repairs, renewals, improvements,
alterations, 

                                       8
<PAGE>
 
strikes, lockouts, picketing, whether legal or illegal, accidents, inability of
the Landlord to obtain fuel or supplies or any other cause or causes beyond the
reasonable control of the Landlord. Any such interruption of service shall never
be deemed an eviction or disturbance of the Tenant's use and possession of the
premises or any part thereof, or render the Landlord liable to the Tenant for
damages, or relieve the Tenant from performance of the Tenant's obligations
under this Lease.

     4.   CONDITION OF PREMISES.  The Tenant's taking possession shall be
conclusive evidence as against the Tenant that the demised premises were in good
order and satisfactory condition when the Tenant took possession except for a
list of items to be completed or repaired, signed by Landlord and Tenant. No
promise of the Landlord to alter, remodel, decorate, clean or improve the
demised premises or the Building and no representation respecting the condition
of the demised premises or the Building have been made by the Landlord to the
Tenant, unless the same is contained herein, or made a part hereof, or in a
written document signed by Landlord. This Lease does not grant any rights to air
over property.

     5.   EXPANSION SPACE POSSESSION.  If the Landlord shall be unable to give
possession of the Expansion Space on the Expansion Space Commencement Date by
reason of the following: (i) the Landlord has not substantially completed the
Tenant Improvements (as hereinafter defined in the Work Letter attached to and
made a part of this Lease), (ii) the Landlord is unable to give possession of
the Expansion Space by reason of the holding over or retention of possession of
any tenant, tenants or occupants, or (iii) for any other reason, Landlord shall
not be subject to any liability for the failure to give possession on said date.
Under such circumstances the rent reserved and covenanted to be paid herein for
the Expansion Space shall not commence until the Expansion Space is available
for occupancy by Tenant, and no such failure to give possession of the Expansion
Space on the Expansion Space Commencement Date shall affect the validity of this
Lease or the obligation of the Tenant hereunder. At the option of Landlord to be
exercised within thirty (30) days of the delayed delivery of possession to
Tenant, the Lease shall be amended so that the term shall be extended by the
period of time possession is delayed. If the Expansion Space is ready for
occupancy prior to the date of the Expansion Date Commencement Date and Tenant
occupies the Expansion Space prior to said date, Tenant shall pay rental for the
period of 

                                       9
<PAGE>
 
occupancy prior to the Expansion Space Commencement Date at the rent stated in
Exhibit "D." The Expansion Space shall be deemed ready for Tenant's occupancy
and substantially complete on the Expansion Space Commencement Date if only
punchlist items of construction, decoration or mechanical adjustments remain to
be completed in the Expansion Space or any part thereof, or if the delay in the
availability of the Expansion Space for occupancy shall be due to special work,
changes, alterations or additions required or made by Tenant in the layout or
finish of the Expansion Space or any part thereof or shall be caused in whole or
in part by Tenant through the delay of Tenant in submitting plans, supplying
information, approving plans, specifications or estimates, giving authorizations
or otherwise or shall be caused in whole or in part by delay and/or default on
the part of Tenant and/or its subtenant or subtenants. In the event of any
dispute as to whether the Expansion Space is ready for Tenant's occupancy or as
to whether the delay in the availability of the Expansion Space for occupancy is
the result of the aforementioned acts or omissions of Tenant, the decision of
Landlord's architect shall be final and binding on the parties.

          In the event the Landlord shall be unable to obtain possession of the
Expansion Space from the current tenant, Lumbermans Mutual Casualty Company
("Lumbermans") and commence the Tenant Improvements on or prior to August 1,
1997 (the "First Termination Date"), Tenant shall have the option ("First
Termination Option") to terminate the Lease by written notice of such
termination delivered to Landlord on or prior to the expiration of five (5) days
after the First Termination Date. In the event Landlord obtains possession of
the Expansion Space from Lumbermans but is unable to substantially complete the
Tenant Improvements or deliver possession of the Expansion Space on or prior to
November 1, 1997 (hereinafter referred to as the "Second Termination Date"),
Tenant shall have the option ("Second Termination Option") to terminate the
Lease by written notice of such termination delivered to Landlord on or prior to
the expiration of five (5) days after the Second Termination Date. Provided,
however, that Landlord's obligation to pay broker commissions are subject to and
conditioned upon the provisions of Paragraph 27(k) of this Lease. Landlord shall
not be deemed in default with respect to delivery of possession or substantial
completion of Tenant's Improvements, if the failure to timely perform is due in
whole or in part to any strike, labor trouble 

                                       10
<PAGE>
 
(whether legal or illegal), civil disorder, failure of power, restrictive
governmental laws and regulations, riots, insurrections, war, shortages,
accidents, casualties, Acts of God, acts, omissions or delays of or caused by
Tenant or any other cause beyond the reasonable control of the Landlord. In such
event the First Termination Date and the Second Termination Date as the case may
be shall be extended, by the number of days possession or substantial completion
has been delayed by such act or events.

     6.   USE OF PREMISES.  The Tenant shall occupy and use the demised premises

of conduct concerning any hazardous, toxic or dangerous substances, waste or
material, now or hereafter in effect.

          Tenant does hereby indemnify, defend and hold harmless the Landlord
and its agents and their respective officers, directors, beneficiaries,
shareholders, partners, agents and employees from all fines, suits, procedures,

Lease.

profession or activities, and shall not use the name of the Building for any
purpose other than that of the business address of the Tenant, and shall never
use any picture or likeness of the Building in any circular, notices,

provisions of this Section 6 or any rules and regulations hereafter adopted, or
the terms, covenants or conditions of any other lease as against any other

licensees. Landlord shall provide written notice of any change 

                                       15
<PAGE>

ordinary wear and tear excepted, caused by Tenant, its agents, employees or
invitees during the term. The Tenant shall pay the Landlord for overtime and for
any other expense incurred in the event repairs, alterations, decorating or
other work in the demised premises are not made during ordinary business hours
at the Tenant's request.

the cost. Unless otherwise agreed by Landlord and Tenant in writing, all such
work shall be performed either by or under the direction of Landlord, but at the
cost of Tenant. The Landlord's decision to refuse such consent shall be
conclusive. If the Landlord's consent to such alterations or additions is
required, the Tenant shall furnish the Landlord for approval:

          (a)  plans and specifications;

          (b)  names and addresses of contractors;

          (c)  copies of contracts;

          (d)  necessary permits;

          (e)  indemnification in form and amount satisfactory to Landlord and
certificates of insurance from all contractors performing labor or furnishing
materials, insuring against any and 

                                       16
<PAGE>
 
all claims, costs, damages, liabilities and expenses which may arise in
connection with the alterations or additions.

     Landlord may withhold approval of any alterations or additions if the plans
or specifications therefor are not acceptable to the Landlord or Landlord's
architect or engineer (if any). In connection with any request for approval of
any alterations or additions by Tenant, Landlord may retain the services of an
outside architect and/or engineer and the reasonable fees of such architect
and/or engineer to Landlord shall be reimbursed to Landlord by Tenant.
Landlord's approval of any plans or specifications shall not be construed to be
an agreement or representation on Landlord's part as to the adequacy or
suitability of the Tenant's alterations or additions.

     In the event Landlord permits the alterations or additions to be completed
by Tenant's contractor, Landlord reserves the right to require that Tenant shall
terminate its contract with any such contractor in the event said contractor
shall be engaged in a labor dispute which disrupts said contractor's work.
Landlord shall also have the right to order any contractor of Tenant who
violates any of Landlord's requirements or standards of work to cease work and
to remove himself, his equipment and his employees from the Building. Tenant
agrees that its contractors shall not conduct their work in such a manner so as
to interfere with or cause any interruption of either (i) Landlord's
construction, (ii) another tenant's occupancy or construction, or (iii) other
phases of Landlord's operation of the Building.

     Whether the Tenant furnishes the Landlord the foregoing or not, the Tenant
hereby agrees to hold the Landlord its beneficiaries, Owner and Owner's partners
and their respective agents and employees harmless from any and all liabilities
of every kind and description which may arise out of or be connected in any way
with said alterations or additions. Any mechanic's lien filed against the
demised premises, or the Building of which the same form a part, for work
claimed to have been furnished to the Tenant shall be discharged of record by
the Tenant within ten (10) days thereafter, at the Tenant's expense. Upon
completing any alterations or additions whether Landlord's approval is required
or not, the Tenant shall furnish the Landlord with contractors' affidavits and
full and final waivers of lien and receipted bills covering all labor and
materials expended and used and a final set 

                                       17
<PAGE>
 
of as-built drawings, plans and specifications. All alterations and additions
shall comply with all insurance requirements and with all ordinances,
regulations, laws and other requirements of any pertinent governmental
authority. All alterations and additions shall be constructed in a good and
workmanlike manner and good grades of materials shall be used.

     All additions, decorations, fixtures, hardware, non-trade fixtures and all
improvements, temporary or permanent, in or upon the demised premises, whether
placed there by the Tenant or by the Landlord, shall, unless the Landlord
identifies the need for their removal at the time of installation, become the
Landlord's property and shall remain upon the demised premises at the
termination of this Lease by lapse of time or otherwise without compensation or
allowance of credit to the Tenant. If, upon the Landlord's request, the Tenant
does not remove said additions, decorations, fixtures, hardware, non-trade
fixtures and improvements earlier identified by Landlord, the Landlord may
remove the same and the Tenant shall pay the cost of such removal to the
Landlord upon demand. Any damage caused by the removal of additions,
decorations, fixtures, hardware, non-trade fixtures and improvements may be
repaired by the Landlord at Tenant's expense.

     9.   ACCESS TO PREMISES.  The Tenant shall permit the Landlord to erect,
use and maintain pipes, ducts, wiring and conduits in and through the Premises.
The Landlord or Landlord's agents shall have the right upon twenty-four (24)
hours prior notice (except for janitorial services or in case of an emergency in
which case Landlord shall notify Tenant as promptly as possible) to enter upon
the premises, to inspect the same, to perform janitorial and cleaning services
and to make such repairs, alterations, improvements or additions to the premises
or the Building as the Landlord may deem necessary or desirable, and the
Landlord shall be allowed to take all material into and upon said demised
premises that may be required therefor without the same constituting an eviction
of the Tenant in whole or in part and the rent reserved shall in no wise abate
(except as provided in Section 10) while said repairs, alterations,
improvements, or additions are being made, by reason of loss or interruption of
business of the Tenant, or otherwise. If the Tenant shall not be personally
present to open and permit an entry into said demised premises, at any time,
when for any reason an entry therein shall be necessary or permissible, the
Landlord or Landlord's agents may enter the same 

                                       18
<PAGE>
 
by a master key, or use reasonable force commensurate with the circumstances to
enter the Premises, without rendering the Landlord or such agents liable
therefor (if during such entry Landlord or Landlord's agents shall accord
reasonable care to Tenant's property), and without in any manner affecting the
obligations and covenants of this Lease. Nothing herein contained, however,
shall be deemed or construed to impose upon the Landlord any obligations,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building or any part thereof, in the exercise of the rights herein provided.
The Landlord shall also have the right at any time without the same constituting
an actual or constructive eviction and without incurring any liability to the
Tenant therefor, to change the arrangement and/or location of entrances or
passages, doors and doorways, and corridors, elevators, stairs, toilets or
public parts of the Building, and to close entrances, doors, corridors,
elevators or other facilities. The Landlord shall not be liable to the Tenant
for any expense, injury, loss or damage resulting from work done in or upon, or
the use of, any adjacent or nearby building, land, street or alley.

     Tenant shall permit Landlord and its agents, upon request, to enter and/or
pass through the premises or any part thereof, at reasonable times during normal
business hours to show the premises to holders of encumbrances on the interest
of Landlord, or prospective purchasers, mortgagees, lessors or tenants of the
Building or any portion thereof. Landlord shall also have the right to enter
and/or pass through the premises, or any part thereof, at such times as such
entry shall be required by circumstances of emergency affecting the premises or
any other portion of the Building.

     10.  UNTENANTABILITY.  If a substantial portion of the demised premises or
the Building is made untenantable by fire or other casualty, Landlord may elect:

          (a)  to terminate this Lease as of the date of the fire or casualty by
notice to the Tenant within ninety (90) days after that date, or

          (b)  proceed with all due diligence to repair, restore or rehabilitate
the Building or the demised Premises, other than leasehold improvements paid for
by Tenant, at Landlord's expense, in which event this Lease shall not terminate.
In the event 

                                       19
<PAGE>
 
Landlord proceeds to repair or restore the Building and Premises but is unable
to complete the repairs or restoration to the Building and Premises within 180
days after such damage has occurred, then Tenant shall have the right to
terminate this Lease by written notice to Landlord which notice must be provided
to Landlord no later than 10 days after the expiration of the 180 day period.
Landlord shall not be deemed in default with respect to repair or restoration of
the Building or the Premises, if the failure to timely perform is due in whole
or in part to any strike, labor trouble (whether legal or illegal), civil
disorder, failure of power, restrictive governmental laws and regulations,
riots, insurrections, war, shortages, accidents, casualties, Acts of God, acts,
omissions or delays of or caused by Tenant or any other cause beyond the
reasonable control of the Landlord. In such event Tenants right to terminate the
Lease shall be extended, by the number of days repair or restoration has been
delayed by such act or events.

     In the event the Lease is not terminated pursuant to these provisions, Base
Rent shall abate on a per diem basis during the period of untenantability. In
the event of the termination of this Lease pursuant to this section, Base Rent
shall be apportioned on a per diem basis and paid to the date of the fire or
other casualty. In the event that the Building or the demised premises is
partially damaged by fire or other casualty but an insubstantial portion of the
Building or the demised premises is made untenantable, then Landlord shall,
except during the last year of the term hereof, proceed with all due diligence
to repair and restore the demised premises or the Building and the Base Rent
shall abate in proportion to the non-usability of the demised premises during
the period of untenantability. If an insubstantial portion of the demised
premises is made untenantable as aforesaid during the last year of the term
hereof, Landlord shall have the right to terminate this Lease as of the date of
the fire or other casualty by giving written notice thereof to Tenant within
thirty (30) days after the date of fire or other casualty, in which event the
Base' Rent shall be apportioned on a per diem basis and paid to the date of such
fire or other casualty. Substantial as referred to in this Section 10 shall be
more than thirty (30%) percent. No damage, compensation or claim shall be
payable by Landlord for inconvenience, loss of business or annoyance arising
from any repair or restoration of any portion of the demised premises or other
portion of the Building except as herein set forth.

                                       20
<PAGE>
 
     11.  INSURANCE.  Tenant shall carry:

          (a)  Comprehensive public liability insurance during the entire term
hereof covering both Tenant and Landlord as insureds to afford protection to the
limits of not less than $2,000,000 for combined single limit bodily injury and
property damage liability.

          (b)  Insurance against fire, sprinkler leakage, vandalism, and the
extended coverage perils for the full replacement value of all additions,
improvements and alterations to the premises, and of all office furniture, trade
fixtures, office equipment, merchandise and all other items of Tenant's property
on the premises.

     All insurance required to be maintained by Tenant shall be on terms and
with companies satisfactory to Landlord. Tenant shall, prior to the commencement
of the term, and during the term, 30 days prior to the expiration of the
policies of insurance, furnish to Landlord certificates evidencing such
coverage, which certificates shall state that such insurance coverage may not be
changed or cancelled without at least thirty (30) days' prior written notice to
Landlord or Tenant.

     12.  SUBROGATION.  The parties hereto agree to have any and all fire,
extended coverage or any and all material damage insurance which may be carried
endorsed with the following subrogation clause: "This insurance shall not be
invalidated should the insured waive prior to a loss any or all right of
recovery against any party for loss occurring to the property described herein";
and each party hereto hereby waives all claims for recovery from the other party
for any loss or damage to any of its property insured under valid and
collectible insurance policies to the extent of any recovery collectible under
such insurance.

     13.  EMINENT DOMAIN.  If a substantial part of the Building, or a
substantial part of the demised premises, shall be lawfully taken or condemned
for any public or quasi-public use or purpose, or conveyed under threat of such
condemnation, the term of this Lease shall end upon, and not before, the date of
the taking of possession by the condemning authority, and without apportionment
of the award. Tenant hereby assigns to the Landlord Tenant's 

                                       21
<PAGE>
 
interest in such award, if any. Current rent shall be apportioned as of the date
of such termination.

     If any part of the Building shall be so taken or condemned, or if the grade
of any street or alley adjacent to the Building is changed by any competent
authority and such taking or change of grade makes it necessary or desirable to
demolish, substantially remodel, or restore the Building, the Landlord shall
have the right to cancel this Lease upon not less than thirty (30) days' notice
prior to the date of cancellation designated in the notice. No money or other
consideration shall be payable by the Landlord to the Tenant for the right of
cancellation, and the Tenant shall have no right to share in the condemnation
award or in any judgment for damages caused by the change of grade.

     If any insubstantial portion of the premises shall be lawfully taken or
condemned or conveyed under threat of condemnation so that the premises can be
used by Tenant for the purposes set forth in Section 6, and this Lease is not
terminated by Landlord, Landlord shall repair the premises, and the Lease shall
be amended to reduce the Tenant's Proportion and Base Rent in the proportion of
the amount taken. No temporary taking of the premises and/or Tenant's rights
therein shall terminate this Lease. Any award made by reason of any such
temporary taking shall belong entirely to Landlord and Tenant shall not be
entitled to share therein.

     14.  ASSIGNMENT-SUBLETTING.  Tenant shall not, without Landlord's prior
written consent which consent shall not be unreasonably withheld:

          (a)  Assign, hypothecate, mortgage, encumber, or convey this Lease or
any interest under it;

          (b)  Allow any transfer thereof or any lien upon Tenant's interest by
operation of law;

          (c)  Sublet the demised premises in whole or in part; or

          (d)  Permit the use or occupancy of the premises by any party other
than Tenant, it agents, employees, guests, invitees and licensees.

                                       22
<PAGE>
 
     The following special provisions relate to cancellation of the Lease upon
assignment or subletting:

               (1)  If Tenant desires at any time to assign this Lease or to
sublet the premises or any portion thereof, it shall first notify Landlord in
writing of its desire to do so not less than forty-five (45) days prior to the
proposed effective date of such assignment or subletting, such notice to include
(a) the name of the proposed subtenant or assignee; (b) the nature of the
proposed subtenant or assignee's business to be carried on in the premises; (c)
the terms and provisions of the proposed sublease or assignment; (d) such
financial information as Landlord may reasonably request concerning the proposed
subtenant or assignee; and (e) an executed copy of the instrument of assignment
or sublease. At any time within ten (10) working days after Landlord's receipt
of the notice and the above required information in a form and content
satisfactory to Landlord, Landlord shall notify the Tenant that:

                    (i)   it consents to the sublease or assignment; or

                    (ii)  it refuses to consent to the sublease or assignment;
or

                    (iii) with respect to the proposed assignment or sublease of
the entire premises that it cancels the Lease effective as of the beginning of
the sublease term or assignment; or

                    (iv)  with respect to the proposed sublease of part of the
premises that, effective as of the beginning of the sublease term, it amends the
Lease to reduce the premises by the portion of the premises proposed to be
sublet and further appropriately amends the Lease because of the reduction of
the premises.

               (2)  The use for which the premises may he sublet shall be only
for lawful office use in keeping with the general character of the Building.

               (3)  If Tenant shall sublet or assign the demised premises at a
rental in excess of the Base Rent and any additional 

                                       23
<PAGE>
 
rent herein provided, any profit generated after reduction of Tenant's expenses
related to such sublet, amortized over the remaining term of the Lease, shall be
divided equally between Landlord and Tenant. Tenant expenses shall be limited to
reasonable legal fees, commissions, Tenants improvements paid for by Tenant and
moving allowance paid by Tenant to the Sublessee.

     Any assignment or subletting shall not release Tenant of liability under
this Lease or permit any subsequent prohibited act, unless specifically provided
in such consent. Tenant agrees to pay to Landlord, on demand, all reasonable
costs incurred by Landlord in connection with any request by Tenant of Landlord
in connection with any consent to any assignment or subletting by Tenant not to
exceed $1,000.00. No assignment shall be binding on Landlord unless such
assignee or Tenant shall deliver to Landlord a counterpart of such assignment
and an instrument which contains a covenant of assumption by the assignee
satisfactory in substance and form to Landlord.

          (4)  Tenant shall have the right to assign or transfer any interest in
this Lease without Landlord's consent to a "Related Transferee," which term
shall mean any of the following: Tenant's parent or any subsidiary or affiliate
of Tenant, or a successor to Tenant by way of merger, consolidation, corporate
reorganization, or the purchase of all or substantially all of Tenant's assets.
Any transfer, sale, pledge or other disposition and/or power to vote the
outstanding shares of corporate stock of Tenant shall not be deemed an
assignment.

     15.  WAIVER OF CLAIMS AND INDEMNITY.  To the extent permitted by law, the
Tenant releases the Landlord, its beneficiaries, partners and their respective
agents and servants from, and waives all claims for, damage to person or
property sustained by the Tenant or any occupant of the Building or premises
resulting from the Building or premises or any part of either or any equipment
or appurtenance becoming out of repair, or resulting from any accident in or
about the Building, or resulting directly or indirectly from any act or neglect
of any tenant or occupant of the Building or any other person, including
Landlord's agents and servants. This Section 15 shall apply especially, but not
exclusively, to the flooding of basements or other subsurface areas, and to
damage caused by refrigerators, sprinkling devices, air-conditioning apparatus,
water, snow, frost, steam, excessive heat or cold, 

                                       24
<PAGE>
 
falling plaster, broken glass, sewage, gas, odors or noise, or the bursting or
leaking of pipes or plumbing fixtures, and shall apply equally whether any such
damage results from the act or neglect of the Landlord or of other tenants,
occupants or servants in the Building or of any other person, and whether such
damage be caused or result from any thing or circumstances above mentioned or
referred to, or any other thing or circumstances whether of a like nature or of
a wholly different nature. If any such damage, whether to the demised premises
or to the Building or any part thereof, or whether to the Landlord or to other
tenants in the Building, results from any act or neglect of the Tenant, its
employees, agents, invitees, and customers, the Tenant shall be liable therefor
and the Landlord may, at the Landlord's option, repair such damage and the
Tenant shall, upon demand by Landlord, reimburse the Landlord forthwith for the
total cost of such repairs. The Tenant shall not be liable for any damage caused
by its act or neglect if the Landlord or a tenant has recovered the full amount
of the damage from insurance and the insurance company has waived its right of
subrogation against the Tenant. All property belonging to the Tenant or any
occupant of the premises that is in the Building or the premises shall be there
at the risk of the Tenant or other person only, and the Landlord shall not be
liable for damages thereto or theft or misappropriation thereof.

     Tenant agrees to indemnify and save the Landlord, its beneficiaries,
partners and their respective agents and employees harmless against any and all
claims, demands, costs and expenses, including reasonable attorneys' fees for
the defense thereof, arising from Tenant's occupation of the demised premises.
In case of any action or proceeding brought against Landlord, its beneficiaries,
Owner and Owner's partners or their respective agents or employees by reason of
any such claim, upon notice from Landlord, Tenant covenants to defend such
action or proceeding by counsel reasonably satisfactory to Landlord.

     16.  MORTGAGE-GROUND LEASE.  Landlord may execute and deliver a mortgage or
trust deed in the nature of a mortgage, both sometimes hereinafter referred to
as "mortgage" against the Building, the Real Property or any interest thereon,
and may sell and lease back the underlying land on which the Building is
situated. If the mortgagee or trustee named in any mortgage or trust deed
hereafter made shall agree that, if it becomes the owner of the Building by
foreclosure or deed in lieu of foreclosure, it 

                                       25
<PAGE>
 
will recognize the rights and interest of Tenant under the Lease and not disturb
Tenant's use and occupancy of the Premises if and so long as Tenant is not in
default under the Lease, then this Lease and the rights of Tenant hereunder
shall thereafter be expressly subject and subordinate at all times to any such
Mortgage and/or ground lease, and all amendments, modifications and renewals
thereof and extensions, consolidations or replacements thereof, and to all
advances made or hereafter to be made upon the security thereof. Tenant agrees
to execute and deliver such further instruments in confirmation of the
subordination of this Lease to said Mortgage or ground lease as may be requested
in writing by Landlord from time to time. Tenant hereby appoints Landlord as
attorney-in-fact for Tenant with full power and authority to execute and deliver
in the name of the Tenant any such instrument in the event Tenant fails to do
so.

     Should any Mortgage affecting the Building or the Real Property be
foreclosed or if any ground or underlying lease be terminated:

          (a)  The liability of the mortgagee, trustee or purchaser at such
foreclosure sale or the liability of a subsequent owner designated as Landlord
under this Lease shall exist only so long as such trustee, mortgagee, purchase
or owner is the owner of the Building or Real Property and such liability shall
not continue or survive after further transfer of ownership.

          (b)  Upon request of the mortgagee or trustee, Tenant will attorn, as
Tenant under this Lease, to the purchaser at any foreclosure sale thereunder, or
if any ground or underlying lease be terminated for any reason, Tenant will
attorn as tenant under this Lease to the ground Lessor under the ground lease
and will execute such instruments as may be necessary or appropriate to evidence
such attornment.

          (c)  Notwithstanding anything to the contrary contained herein,
Mortgagee by notice in writing to Tenant may subordinate its Mortgage to this
Lease.

     17.  CERTAIN RIGHTS RESERVED TO THE LANDLORD.  The Landlord reserves and
may exercise the following rights without affecting Tenant's obligations
hereunder:

                                       26
<PAGE>
 
          (a)  to change the name or street address of the Building;

          (b)  to install and maintain a sign or signs on the interior or
exterior of the Building;

          (c)  to have access for the Landlord and the other tenants of the
Building to any mail chutes located on the demised premises according to the
rules of the United States Post Office;

          (d)  to designate all sources furnishing sign painting and lettering,
ice, drinking water, towels, coffee cart service and toilet supplies, lamps and
bulbs used on the demised premises;

          (e)  to decorate, remodel, repair, alter or otherwise prepare the
demised premises for reoccupancy if Tenant vacates the demised premises prior to
the expiration of the term, and is in default of any provision of this Lease;

          (f)  to retain at all times pass keys to the demised premises;

          (g)  to grant to anyone the exclusive right to conduct any particular
business or undertaking in the Building;

          (h)  to exhibit the demised premises to others and to display "For
Rent" signs on the demised premises;

          (i)  to close the Building after regular working hours and on legal
holidays subject, however, to Tenant's right to admittance, under such
reasonable regulations as Landlord may prescribe from time to time, which may
include by way of example but not of limitation, that persons entering or
leaving the Building identify themselves to a watchman by registration or
otherwise and that said persons establish their right to enter or leave the
Building;

          (j)  to approve the weight, size and location of safes or other heavy
equipment or articles, which articles may be moved in, about, or out of the
Building or premises only at such times and in 

                                       27
<PAGE>
 
such manner as Landlord shall direct and in all events, however, at Tenant's
sole risk and responsibility;

          (k)  to designate and/or approve, prior to installation, all types of
window shades, blinds, drapes, awnings, window ventilators and other similar
equipment, and to control all internal lighting that may be visible from the
exterior of the building.

          (l)  to take any and all measures, including inspections, repairs,
alterations, decorations, additions and improvements to the premises or to the
Building, as may be necessary or desirable for the safety, protection or
preservation of the premises or the Building or the Landlord's interests, or as
may be necessary or desirable in the operation of the Building.

     The Landlord may enter upon the demised premises and may exercise any or
all of the foregoing rights reserved without being deemed guilty of an eviction
or disturbance of the Tenant's use or possession and without being liable in any
manner to the Tenant and without abatement of rent or affecting any of the
Tenant's obligations hereunder.

     18.  HOLDING OVER.  If the Tenant retains possession of the demised
premises or any part thereof after the termination of the term or any extension
thereof, by lapse of time or otherwise, the Tenant shall pay the Landlord the
monthly rent,  (including Rent Adjustment which Landlord may reasonably
estimate) at double the rate payable for the month immediately preceding said
holding over, computed on a per-month basis, for each month or part thereof that
the Tenant thus remains in possession, and in addition thereto, Tenant shall pay
the Landlord all damages, consequential as well as direct, sustained by reason
of the Tenant's retention of possession, provided, however, that Tenant shall
not be responsible for consequential damages incurred during the first thirty
(30) days of any such holdover. Such tenancy shall be subject to every other
term, covenant and agreement contained herein. The provisions of this paragraph
do not exclude the Landlord's rights of re-entry or any other right here-under.

     19.  LANDLORD'S REMEDIES.  All rights and remedies of the Landlord herein
enumerated shall be cumulative, and none shall exclude any other right or remedy
allowed by law.

                                       28
<PAGE>
 
intentionally omitted

          (a)  If the Tenant defaults in the payment of rent, and the Tenant
does not cure the default within ten (10) days after demand for payment of such
rent or if the Tenant defaults in the prompt and full performance of any other
provisions of this Lease, and the Tenant does not cure the default within thirty
(30) days after written demand by the landlord that the default be cured (unless
the default involves a hazardous condition, which shall be cured forthwith) or
if the leasehold interest of the Tenant be levied upon under execution or be
attached by process of law or if the Tenant makes an assignment for the benefit
of creditors or admits its inability to pay its debts or if a receiver he
appointed for any property of the Tenant, or if Tenant abandons the premises and
is in default of any provision of this Lease, then and in any such event the
Landlord may, if the Landlord so elects but not otherwise, and with or without
notice of such election, and with or without any demand whatsoever, either
forthwith terminate this Lease and the Tenant's right to possession of the
premises or, without terminating this Lease, forthwith terminate the Tenant's
right to possession of the premises.

          (b)  Upon any termination of this Lease, whether by lapse of time or
otherwise, or upon any termination of the Tenant's right to possession without
termination of the Lease, the Tenant shall surrender possession and vacate the
premises immediately, and deliver possession thereof to the Landlord, and hereby
grants to the Landlord full and free license to enter into and upon the premises
in such event with or without process of law and to repossess the Landlord of
the premises as of the Landlord's former estate and to expel or remove the
Tenant and any' others who may be occupying or be within the premises and to
remove any and all property therefrom, using such force as may be necessary,
without being deemed in any manner guilty of trespass, eviction or forcible
entry or detainer, and without relinquishing the Landlord's rights to rent or
any other right given to the Landlord hereunder or by operation of law.

          (c)  Upon termination of the Lease, Landlord shall be entitled to
recover as damages a sum of money equal to the present value, on the date of
termination, of the Rent provided herein to be paid by Tenant to Landlord for
the remainder of the Lease term 

                                       29
<PAGE>
 
plus all rent accrued and unpaid up to and including the termination date.

          (d)  In the event Landlord elects to terminate Tenant's right to
possession without terminating the Lease the Landlord shall take reasonable
measures to relet all or any part of the Premises for such rent and upon such
terms as shall be satisfactory to Landlord (including the right to relet the
Premises for a term greater or lesser than that remaining under the Lease Term,
and the right to relet the Premises as part of a larger area, and the right to
change the character or use made of the Premises). For the purpose of such
reletting, Landlord may decorate or make any repairs, changes, alterations or
additions in or to the Premises that may be necessary or convenient. If Landlord
is unable to relet the Premises, Tenant shall pay to Landlord on demand the
present value, at the time of default, of the Rent herein to be paid by Tenant
for the remainder of the Lease Term, plus all rent accrued and unpaid at the
time of default. If the Premises are relet and a sufficient sum shall not be
realized from such reletting after paying all of the expenses of such
decoration, repairs, changes, alterations, additions, the expenses of such
reletting and the collection of the rent accruing therefrom (including but not
by of limitation, reasonable attorney's fees and brokers' commissions), to
satisfy the Rent herein provided to be paid for the remainder of the Lease Term,
Tenant shall pay to Landlord on demand any deficiency. Landlord shall not be
deemed to have failed to use reasonable measures to relet the Premises by reason
of the fact that Landlord has leased or sought to lease other vacant premises in
the building in preference to reletting the Premises, or by reason of the fact
that Landlord has sought to relet the Premises at a rental rate higher than that
payable by Tenant under the Lease (but not in excess of the then current market
rental rate).

          (e)  Any and all property which may be removed from the premises by
the Landlord pursuant to the authority of the Lease or of law, to which the
Tenant is or may be entitled, may be handled, removed or stored by the Landlord
at the risk, cost and expense of the Tenant, and the Landlord shall in no event
be responsible for the value, preservation or safekeeping thereof. The Tenant
shall pay to the Landlord, upon demand, any and all expenses incurred in such
removal and all storage charges against such property so long as the same shall
be in the Landlord's possession or under the 

                                       30
<PAGE>
 
Landlord's control. Any such property of the Tenant not retaken from storage by
the Tenant within thirty (30) days after the end of the term, however
terminated, shall be conclusively presumed to have been conveyed by the Tenant
to the Landlord under this Lease as a bill of sale without further payment or
credit by the Landlord to the Tenant.

          (f)  Tenant hereby grants to Landlord a first lien upon the interest
of Tenant under this Lease to secure the payment of moneys due under this Lease,
which lien may be enforced in equity; and Landlord shall be entitled as a matter
of right to have a receiver appointed to take possession of the demised premises
and relet the same under order of court.

          (g)  The Tenant shall pay upon demand all the Landlord's costs,
charges and expenses, including the fees of counsel, agents and others retained
by the Landlord, incurred in performing or in enforcing the Tenant's obligations
hereunder or incurred by the Landlord in any litigation, negotiation or
transaction in which the Tenant causes the Landlord, without the Landlord's
fault, to become involved or concerned.

          (h)  The obligation of Tenant to pay the Rent reserved during the
balance of the Term, or during any extension, or any holdover tenancy created by
acts of the parties shall not be deemed to be waived, released or terminated, by
the service of any five-day notice, other notice to collect, demand for
possession, or notice that the tenancy hereby created will be terminated on the
date therein named, the institution of any action of forcible detainer or
ejectment or any judgment for possession that may be rendered in such action, or
any other act or acts resulting in the termination of the Lease of Tenant's
right to possession of the Premises.

          (i)  Tenant agrees that Landlord may file suit to recover any sums due
to Landlord under this Lease from time to time and that such suit or recovery of
any amount due Landlord hereunder shall not be any defense to any subsequent
action brought for any amount not theretofore reduced to judgment in favor of
Landlord.

equivalent yield of U.S. Treasury Bonds having the same maturity as the

Wall Street Journal shall be used for the purpose of calculating present value
in paragraphs 19 (c) and (d).

     20.  DEFAULT UNDER OTHER LEASE.  If the term of any lease, other than this
Lease, made by the Tenant for any other demised premises in the Building shall
be terminated or terminable after the making of this Lease because of any
default by the Tenant under such other lease, such fact shall empower the
Landlord, at the Landlord's sole option, to terminate this Lease by notice to
the Tenant.

     21.  SURRENDER OF POSSESSION.  Upon the expiration or other termination of
the term of this Lease, Tenant shall quit and surrender to Landlord the
premises, broom clean, in good order and condition, ordinary wear excepted, and
Tenant shall remove all of its property except as otherwise provided in Section
8.

     If the Tenant does not remove its property of every kind and description
from the demised premises prior to the end of the term, however ended, and
Landlord shall not have requested the removal of same by Tenant pursuant to
Section 8 hereof, the Tenant shall be conclusively presumed to have conveyed the
same to the Landlord under this Lease as a bill of sale without further payment
or credit by the Landlord to the Tenant and the Landlord may remove the same and
the Tenant shall pay the cost of such removal to the Landlord upon demand.

     Tenant's obligations to observe or perform this covenant shall survive the
expiration or other termination of the term of this Lease.

     24.  SECURITY DEPOSIT.  Tenant agrees to deposit with Landlord, upon the
execution of this Lease, the sum of $22,295.59 as security for the full and
faithful performance by Tenant of each and every term, provision, covenant and
condition of this Lease. If Tenant defaults in respect to any of the terms,
provisions, covenants and conditions of this Lease including, but not limited
to, payment of the Base Rent and Rent Adjustments, Landlord may use, apply or
retain the whole or any part of the security so deposited for the payment of any
such rent in default, or for any other sum which the Landlord may expend or be
required to expend by reason of Tenant's default including, without limitation,
any damages or deficiencies in the reletting of the demised premises, whether
such damages or deficiency shall have accrued before or after any re-entry by
Landlord.  If any of the security shall be so used, applied or retained by
Landlord at any time or from time to time, Tenant shall promptly, in each such
instance, on written demand therefor by Landlord, pay to Landlord such
additional sum as may be necessary to restore the security to the original
amount set forth in the first sentence of this paragraph.  If Tenant shall fully
and faithfully comply with all the terms, provisions, covenants and conditions
of this Lease, the security, or any balance thereof, shall be returned to Tenant
after the following:

          (a)  the time fixed as the expiration of the term of this Lease;

          (b)  the removal of Tenant and its property from the demised premises;

          (c)  the surrender of the demised premises by Tenant to Landlord in
accordance with this Lease; and

          (d)  the time required for the Rent Adjustment due pursuant to the
Lease to have been computed by Landlord and paid by Tenant.

                                       33
<PAGE>
 
     Except as otherwise required by law, Tenant shall not be entitled to any
interest on the aforesaid security.  In the absence of evidence satisfactory to
Landlord of an assignment of the right to receive the security or the remaining
balance thereof, Landlord may return the security to the original Tenant,
regardless of one or more assignments of this Lease.  Upon the transfer of
Landlord's interest under this Lease, Landlord's obligation to Tenant with
respect to the security deposit shall terminate upon assumption of such
obligation by the transferee.

     25.  COVENANT AGAINST LIENS.  Tenant has no authority or power to cause or
permit any lien or encumbrance of any kind whatsoever, whether created by act of
Tenant, operation of law or otherwise, to attach to or be placed upon Landlord's
title or interest in the Real Property and any and all liens and encumbrances
created by Tenant shall attach to Tenant's interest only.  Tenant covenants and
agrees not to suffer or permit any lien of mechanics or materialmen or others to
be placed against the Land, Building or the premises with respect to work or
services claimed to have been performed for or materials claimed to have been
furnished to Tenant or the premises, and in case of any such lien attaching,
Tenant covenants and agrees immediately to cause it to be released and removed
of record.

     26.  RENEWAL OPTION.

          (a)  Tenant shall have one option to renew (the "Renewal Option") the
Lease for one (1) additional five (5) year term to commence June 1, 2002 and
terminate May 31, 2007 (the "Renewal Term") upon notifying Landlord in writing
of the election to renew the Lease, not less than one hundred eighty (180) days
prior to the Expiration Date (the "Option Notice").

          (b)  Annual Base Rent for the Renewal Term shall be the greater of 95%
of the current market rental rate ("Market Rent") prevailing at the time of the
Option Notice or $309,401.34. Landlord shall advise Tenant in writing regarding
Landlord's proposed Market Rent within ten (10) business days of Landlord's
receipt of the Option Notice.

          (c)  For purposes of the Lease "Market Rent" shall mean the annual
rate of rent per square foot of rentable area, including concessions, if any,
and building standard tenant improvement 

                                       34
<PAGE>
 
allowance for leases with comparable term commencing on or about the same time
such rate is to be determined for comparable space in similar buildings within
the same geographic area for the same term in arm's length transactions between
a landlord and a willing and informed tenant.

          (d)  If Tenant disagrees with Landlord's determination of "Market
Rent", the parties shall meet and attempt to resolve their disagreement within
fifteen (15) business days after Landlord's notice to Tenant designating the
"Market Rent".  If Landlord and Tenant fail to reach agreement, then the
following procedure shall be followed:  within five (5) business days after the
expiration of the fifteen (15) day period described above, Landlord shall
promptly select an MAI appraiser or other real estate professional and Tenant
shall promptly select an MAI appraiser or other real estate professional (said
two appraisers or professionals are herein the "Initial Appraisers").  Each
appraiser shall be independent, familiar with office buildings and rents in the
north suburban Chicago area and with a minimum of ten (10) years experience in
evaluating office rents.  If either Landlord or Tenant fails to designate its
Initial Appraiser within the five (5) business days described above, then the
Initial Appraiser that has been duly designated by the other party shall
determine the "Market Rent".  The cost of each Initial Appraiser shall be paid
by the party selecting such appraiser.  Each appraiser shall submit to Landlord
and Tenant, within fifteen (15) business days after both appointments, its
written appraisal of the "Market Rent" with respect to the space to be leased
based on a five (5) year term beginning as of the date of the Option Notice.  If
the appraisals of the "Market Rent" determined by the Initial Appraisers are
less than ten percent (10%) apart (i.e., the higher appraisal is less than one
                                   ----                                       
hundred ten percent (110%) of the lower appraisal), the "Market Rent" shall be
determined by taking the average of the two (2) appraisals.  In the event the
appraisals of the "Market Rent" determined by the Initial Appraisers are ten
percent (10%) or more apart (i.e., the higher appraisal is one hundred ten
                             ----                                         
percent (110%) or more of the lower appraisal), the Initial Appraisers shall,
within five (5) business days thereafter, select a third appraiser with the same
qualifications or who meets the same criteria as required of the Initial
Appraisers ("Third Appraiser").  The Third Appraiser shall submit to Landlord
and Tenant, within fifteen (15) business days after its appointment, its written
appraisal of the "Market Rent" with respect to the space to be leased as of the

                                       35
<PAGE>
 
Option Notice. The cost of the Third Appraiser shall be borne equally by
Landlord and Tenant. If the appraisal of the Third Appraiser is ten percent
(10%) or less at variance from the point that is equidistant between the
appraisals of the Initial Appraisers, the average of the three (3) appraisals
shall determine the "Market Rent". If the appraisal of the Third Appraiser is
more than ten percent (10%) at variance from the point that is equidistant
between the appraisals of the Initial Appraisers, the "Market Rent" shall be
determined by taking the average of the two (2) closest appraisals.

          (e)  In the event Tenant exercises the Renewal Option, Landlord and
Tenant shall, within ten (10) days of the determination of the "Market Rent",
execute an amendment to the Lease to include the new Monthly Base Rent and
Annual Base Rent.

          (f)  The Renewal Option shall automatically terminate upon the
earliest to occur of: (i) the expiration or termination of the Lease; (ii) the
termination of Tenant's right to possession of the Premises; (iii) the failure
of Tenant to timely or properly exercise the Renewal Option; (iv) Tenant's
default in the performance of its obligations under the Lease which have not
been cured within the applicable grace period, if any; or (v) Tenant's
assignment or sublease of its interest under the Lease.

     27.  MISCELLANEOUS.

          (a)  No receipt of money by the Landlord from the Tenant after the
termination of this Lease or after the service of any notice or after the
commencement of any suit, or after final judgment for possession of the demised
premises shall reinstate, continue to extend the term of this Lease or affect
any such notice, demand or suit.

          (b)  No waiver of any default of the Tenant hereunder shall be implied
from any omission by the Landlord to take any action on account of such default
if such default persists or be repeated, and no express waiver shall affect any
default other than the default specified in the express waver and then only for
the time and to the extent therein stated.

          (c)  The words "Landlord" and "Tenant" wherever used in the Lease
shall be construed to mean plural where necessary, and

                                       36
<PAGE>
 
the necessary grammatical changes required to make the provisions hereof apply
either to corporations or individuals, men or women, shall in all cases be
assumed as though in each case fully expressed.

          (d)  Each provision hereof shall extend to and shall, as the case may
require, bind and inure to the benefit of the Landlord and the Tenant and their
respective heirs, legal representatives, successors and assigns in the event
this Lease has been assigned by Landlord or by Tenant with the express written
consent of the Landlord.

          (e)  Submission of this instrument for examination does not constitute
a reservation of or option for the premises.  The instrument does not become
effective as a lease or otherwise until executed and delivered by both Landlord
and Tenant.

          (f)  All amounts (unless otherwise provided herein, and other than the
Base Rent and Rent Adjustment which shall be due as hereinbefore provided) owed
by the Tenant to the Landlord hereunder shall be deemed additional rent and be
paid within ten (10) days from the date the Landlord renders statements of
account therefor. All such amounts (including Base Rent and Rent Adjustment)
shall bear interest from the date due until the date paid at the rate of 2%
above the announced Corporate Base rate of interest in effect at The First
National Bank of Chicago on the date of payment or at the maximum legal rate of
interest, allowed by law, if such maximum legal rate is applicable and lower.
Whenever rent is referred to in this Lease, it shall include Base Rent, Rent
Adjustment and Additional Rent.

          (g)  All riders attached to this Lease and initialed by the Landlord
and the Tenant are hereby made a part of this Lease as though inserted in this
Lease.

          (h)  The headings of sections are for convenience only and do not
limit or construe the contents of the sections.

          (i)  If the Tenant shall occupy the premises prior to the beginning of
the term of this Lease with the Landlord's consent, all the provisions of this
Lease shall be in full force and effect as soon as the Tenant occupies the
premises.

                                       37

          (j)  INTENTIONALLY OMITTED

          (k)  Landlord and Tenant represent that they have dealt directly with
and only with LaSalle Partners and U.S. Equities as broker in connection with
this Lease, and that insofar as the Landlord and Tenant know no other broker
negotiated this Lease or is entitled to any commission in connection therewith.
Landlord and Tenant each indemnifies and holds the other and its beneficiaries,
partners and their respective agents and employees harmless from all claims of
any other broker or brokers in connection with this Lease.  Landlord shall not
be obligated to pay any brokers' commissions or other fees to any persons or
brokers for (i) the Expansion Space if Tenant exercises the First Termination
Option or the Second Termination Option or (ii) the Initial Space for the
remaining term of the Lease for the Initial Space if and after the Tenant
exercises the First or Second Termination Option.

          (l)  The Tenant agrees that from time to time upon not less than ten
(10) business days' prior request by the Landlord, the Tenant will deliver to
the Landlord a statement in writing certifying (a) that this Lease is unmodified
and in full force and effect (or if there have been modifications that the same
is in full force and effect as modified and identifying the modifications), (b)
the dates to which the rent and other charges have been paid, and (c) that so
far as the person making the certificate knows, the Landlord is not in default
under any provision of this Lease.

               The Landlord's title is and always shall be paramount to the
title of the Tenant, and nothing herein contained shall empower the Tenant to do
any act which can, shall or may encumber such title.

          (n)  The laws of the State of Illinois shall govern the validity,
performance and enforcement of this Lease.

          (o)  If any term, covenant or condition of this Lease or the
application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such term, covenant or condition to persons or circumstances other than those as
to which it is held invalid or unenforceable, shall not be affected thereby and
each term, 

                                       38
<PAGE>
 
covenant or condition of this Lease shall be valid and be enforced to the
fullest extent permitted by law.

          (p)  Landlord has no obligation pursuant to this Lease except as
expressly provided for herein.  Landlord's or Owner's liability hereunder shall
cease upon the transfer of Landlord's or Owner's interest in this Lease.

          (q)  This Lease and Tenant Work Agreement, if any, set forth all the
covenants, promises, agreements, conditions and understandings between Landlord
and Tenant, concerning the demised premises and there are no covenants,
promises, agreements, conditions or understandings, either oral or written,
between them other than are herein set forth.  Except as herein otherwise
provided, no subsequent alteration, amendment, change or addition to this Lease
shall be binding upon Landlord or Tenant unless reduced to writing and signed by
them.

          (r)  The undersigned signators warrant that they have full power and
authority to execute this Lease on behalf of the respective parties hereto.

     28.  RESERVATION OF RIGHTS.  Notwithstanding any provision of Section 6(b)
or Section 15 or the Lease to the contrary, no agreement of Tenant in Section
6(b) or 15 shall be deemed to exempt Landlord from liability for damage or
injury to persons or damage to property caused by or resulting from the
negligence or willful conduct of Landlord, its agents, servants, or employees in
the operation or maintenance of the Premises or the Building.

     29.  EXCULPATORY CLAUSE.  This Lease is executed by LaSalle National Trust,
N.A. as Successor Trustee to LaSalle National Bank, not personally, but solely
as Trustee under a Trust Agreement dated October 8, 1982 and known as Trust No.
105454, in the exercise of the power and authority conferred upon and vested in
it as such Trustee, and under the express direction of the beneficiaries of a
certain Trust Agreement dated October 8, 1982 and known as Trust No. 105454.  It

generality of the foregoing, there shall be no personal liability to pay any
indebtedness accruing hereunder or to perform any covenants, either 

                                       39

beneficiaries and has no authority to bind the beneficiaries to perform any
covenant or agreement herein, and that all personal liability of said Trustee
(and said beneficiaries and their agents, to the extent permitted by law) of
every sort, if any, is hereby expressly waived by Tenant, and every person now
or hereafter claiming any right or security hereunder; and that so far as the
parties hereto are concerned the owner of any indebtedness of liability accruing
hereunder shall look solely to the trust estate from time to time subject to the
provisions of said Trust Agreement for payment thereof. It is further understood
and agreed that the said trustee has no agents or employees and merely holds
naked legal title to the property herein described and has no knowledge

                    ------- 

          reference to any Person includes such Person's successors and assigns
but, if applicable, only if such successors and assigns are permitted by this
Agreement or such other Loan Document, as the case may be, and reference to a
Person in a particular capacity excludes such Person in any other capacity; and

          1.2.8     Modifications to Documents.

          reference to any agreement (including this Agreement and any other
Loan Document together with the schedules and exhibits hereto or thereto),
document or instrument means such agreement, document or instrument as amended,
modified, replaced, substituted for, superseded or restated.

     1.3  Accounting Principles.
          --------------------- 

     Except as otherwise provided in this Agreement, all computations and
determinations as to accounting or financial matters and all financial
statements to be delivered pursuant to this Agreement shall be made and prepared
in accordance with GAAP (including principles of consolidation where
appropriate), and all accounting or financial terms shall have the meanings
ascribed to such terms by GAAP; provided, however, that all accounting terms
                                --------  -------                           
used in Section 7.2 (and all defined terms used in the definition of any
accounting term used in Section 7.2 shall have the meaning given to such terms
(and defined terms) under GAAP as in effect on the date hereof applied on a
basis consistent with those used in preparing the Annual Statements referred to
in Section 5.1.9(i).  In the event of any change after the date hereof in GAAP,
and if such change would result in the inability to determine compliance with
the financial covenants set forth in Section 7.2 based upon the Borrowers'
regularly prepared financial statements by reason of the preceding sentence,
then the parties hereto agree to endeavor, in good faith, to agree upon an
amendment to this Agreement that would adjust such financial covenants in a
manner that would not affect the substance thereof, but would allow compliance
therewith to be determined in accordance with the Borrowers' financial
statements at that time.  In any determination of net income for purposes of
this Agreement, Borrowers shall treat all development costs and other intangible
items as items of expense rather than capitalizing such development costs and
other intangible items; provided, however, that if permitted by GAAP, the
Borrowers may capitalize up to $1,000,000 of such development costs and other
intangible items over any twelve month period.

                             -------------------------
                                        
     2.1  Revolving Credit Commitments.
          ---------------------------- 

     Subject to the terms and conditions hereof and relying upon the
representations and warranties herein set forth, and subject to Availability,
each Bank severally agrees to make Loans to the Borrowers at any time or from
time to time on or after the date hereof to the Expiration Date provided that
after giving effect to such Loan the aggregate amount of Loans from such Bank
shall not exceed such Bank's Revolving Credit Commitment minus such Bank's
Ratable Share of the Letters of Credit Outstanding.  Within such limits of time
and amount and subject to the other provisions of this Agreement, the Borrowers
may borrow, repay and reborrow pursuant to this Section 2.1.

     2.2  Nature of Banks' Obligations with Respect to Revolving Credit Loans.
          ------------------------------------------------------------------- 

     Each Bank shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 2.5 in accordance with its Ratable
Share.  The aggregate of each Bank's Loans outstanding hereunder to the
Borrowers at any time shall never exceed its Revolving Credit Commitment minus
its Ratable Share of the Letter of Credit Outstandings.  The obligations of each
Bank hereunder are several.  The failure of any Bank to perform its obligations
hereunder shall not affect the Obligations of the Borrowers to any other party
nor shall any other party be liable for the failure of such Bank to perform its
obligations hereunder.  The Banks shall have no obligation to make Loans
hereunder on or after the Expiration Date.

     2.3  Commitment Fees.
          --------------- 

     Accruing from the date hereof until the Expiration Date, the Borrowers
agree to pay to the Agent for the account of each Bank, as consideration for
such Bank's Revolving Credit Commitment hereunder, a nonrefundable commitment
fee (the "Commitment Fee") equal to 3/8% per annum (computed on the basis of a
year of 365 or 366  days, as the case may be, and actual days elapsed) on the
average daily difference between the amount of (i) such Bank's Revolving Credit
Commitment as the same may be constituted from time to time and the (ii) the
principal amount of the Revolving Credit Loans outstanding and such Bank's
Ratable Share of Letters of Credit Outstanding .  All Commitment Fees shall be
payable in arrears on the first Business Day of each January, April, July and
September after the date hereof and on the Expiration Date or upon acceleration
of the Notes.

     2.4  Closing Fee.
          ------------

     The Borrowers agree jointly and severally to pay to the Agent for the
account of each Bank, as consideration for such Bank's Revolving Credit
Commitment, a nonrefundable Closing fee equal to 3/8% of such Bank's Revolving
Credit Commitment, payable on the Closing Date.

Section 3.2, by delivering to the Agent, not later than 1:00 p.m., Eastern time,
(i) three (3) Business Days prior to the proposed Borrowing Date with respect to
the making of Loans to which the Euro-Rate Option applies or the conversion to
or the renewal of the Euro-Rate Option for any Loans; and (ii) the same day as
the Borrowing Date with respect to the making of a Loan to which the Base Rate
Option applies or the last day of the preceding Interest Period with respect to
the conversion to the Base Rate Option for any Loan, of a duly completed request
therefor substantially in the form of Exhibit 2.5 or a request by telephone
                                      -----------                          
immediately confirmed in writing by letter, facsimile or telex in such form
(each, a "Loan Request"), it being understood that the Agent may rely on the
authority of any individual making such a telephonic request without the
necessity of receipt of such written confirmation.  Each Loan Request shall be
irrevocable and shall specify (i) the proposed Borrowing Date; (ii) the
aggregate amount of the proposed Revolving Credit Loans comprising each
Borrowing Tranche, which, for Loans to which the Euro-Rate Option applies  shall
be not less than $1,000,000 for each Borrowing Tranche and in integral multiples
of $100,000 and for Borrowing Tranches to which the Base Rate Option applies not
less than the lesser of $100,000 or the maximum amount available; (iii) whether
the Euro-Rate Option or Base Rate Option shall apply to the proposed Revolving
Credit Loans comprising the applicable Borrowing Tranche; and (iv) in the case
of a Borrowing Tranche to which the Euro-Rate Option applies, an appropriate
Interest Period for the proposed Loans comprising such Borrowing Tranche.  The
Borrowers may have no more than five Borrowing Tranches at any time including
the Base Rate Tranche.

     2.6  Making Loans.
          ------------ 

     The Agent shall, promptly after receipt by it of a Loan Request pursuant to
Section 2.5, notify the Banks of its receipt of such Loan Request specifying:
(i) the proposed Borrowing Date and the time and method of disbursement of the
Loans requested thereby; (ii) the amount and type of each such Loan and the
applicable Interest Period (if any); and (iii) the apportionment among the Banks
of such Loans as determined by the Agent in accordance with Section 2.2. Each
Bank shall remit the principal amount of each Loan to the Agent such that the
Agent is able to, and the Agent shall, to the extent the Banks have made funds
available to it for such purpose and subject to Section 6.2, fund such Revolving
Credit Loans to the Borrowers in U.S. Dollars and immediately available funds at
the Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable
Borrowing Date, provided that if any Bank fails to remit such funds to the Agent
in a timely manner, the Agent may elect in its sole discretion to fund with its
own funds the Revolving Credit Loans of such Bank on such Borrowing Date, and
such Bank shall be subject to the repayment obligation in Section 9.16.

principal amount of the Revolving Credit Loans made by each Bank, together with
interest thereon, shall be joint and several and shall be evidenced by a Note
dated the Closing Date payable to the order of such Bank in a face amount equal
to the Revolving Credit Commitment of such Bank.

          2.8  Use of Proceeds.
               --------------- 

          The proceeds of the Revolving Credit Loans shall be used to finance

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

               2.9.1     Issuance of Letters of Credit.
                         ----------------------------- 

               Any Borrower may request the issuance of a letter of credit (each
a "Letter of Credit") on behalf of itself or another Loan Party by delivering to
the Agent a completed application and agreement for standby letters of credit in
such form as the Agent may specify from time to time by no later than 10:00
a.m., Pittsburgh time, at least three (3) Business Days, or such shorter period
as may be agreed to by the Agent, in advance of the proposed date of issuance.
Subject to the terms and conditions hereof and in reliance on the agreements of
the other Banks set forth in this Section 2.9, the Agent will issue a Letter of
Credit provided that each Letter of Credit shall (A) have a maximum maturity of
twelve (12) months from the date of issuance, and (B) in no event expire later
than one Business Day prior to the Expiration Date and providing that in no
event shall (i) the Letters of Credit Outstanding exceed, at any one time, Two
Million Dollars ($2,000,000) or (ii) the Revolving Facility Usage exceed, at any
one time, the Revolving Credit Commitments. If the Expiration Date is extended
pursuant to Section 2.10, the Borrowers may request renewals of Letters of
Credit.

               2.9.2     Letter of Credit Fees.
                         --------------------- 

               The Borrowers shall pay (i) to the Agent for the ratable account
of the Banks a fee (the "Letter of Credit Fee") equal to the Applicable Margin
per annum for Euro-Rate Loans and (ii) to the Agent for its own account a
fronting fee equal to 1/8% per annum, which fees shall be computed on the daily
average Letters of Credit Outstanding and shall be payable quarterly in arrears
commencing with the first Business Day of each January, April, July and October
following issuance of each Letter of Credit and on the Expiration Date. The
Borrowers shall also pay to the Agent for the Agent's sole account the Agent's
then in effect customary fees and administrative expenses payable with respect
to the Letters of Credit as the Agent may generally charge or incur from time to
time in connection with the issuance, maintenance, modification (if any),
assignment or transfer (if any), negotiation, and administration of Letters of
Credit.

               2.9.3     Disbursements, Reimbursement.
                         ---------------------------- 

                    2.9.3.1   Immediately upon the Issuance of each Letter of
Credit, each Bank shall be deemed to, and hereby irrevocably and unconditionally
agrees to, purchase from the Agent a participation in such Letter of Credit and
each drawing thereunder in an amount equal to such Bank's Ratable Share of the
maximum amount available to be drawn under such Letter of Credit and the amount
of such drawing, respectively.

                    2.9.3.2   In the event of any request for a drawing under a
Letter of Credit by the beneficiary or transferee thereof, the Agent will
promptly notify the Borrowers. Provided that they shall have received such
notice, the Borrowers shall reimburse (such obligation to reimburse the Agent
shall sometimes be referred to as a "Reimbursement Obligation") the Agent prior
to 12:00 noon, Pittsburgh time on each date that an amount is paid by the Agent
under any Letter of Credit (each such date, an "Drawing Date") in an amount
equal to the amount so paid by the Agent. In the event the Borrowers fail to
reimburse the Agent for the full amount of any drawing under any Letter of
Credit by 11:00 a.m., Pittsburgh time, on the Drawing Date, the Agent will
promptly notify each Bank thereof, and the Borrowers shall be deemed to have
requested that Loans be made by the Banks under the Base Rate Option to be
disbursed on the Drawing Date under such Letter of Credit, subject to the amount
of the unutilized portion of the Revolving Credit Commitment and subject to the
conditions set forth in Section 6.2 other than any notice requirements. Any
notice given by the Agent pursuant to this Section 2.9.3.2 may be oral if
immediately confirmed in writing; provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such
notice.

                    2.9.3.3   Each Bank shall upon any notice pursuant to
Section 2.9.3.2 make available to the Agent an amount in immediately available
funds equal to its Ratable Share of the amount of the drawing, whereupon the
participating Banks shall (subject to Section 2.9.3.4) each be deemed to have
made a Loan under the Base Rate Option to the Borrowers in that amount. If any
Bank so notified fails to make available to the Agent for the account of the
Agent the amount of such Bank's Ratable Share of such amount by no later than
2:00 p.m., Pittsburgh time on the Drawing Date, then interest shall accrue on
such Bank's obligation to make such payment, from the Drawing Date to the date
on which such Bank makes such payment, at a rate per annum equal to the Federal
Funds Effective Rate in effect from time to time during such period. The Agent
will promptly give notice of the occurrence of the Drawing Date, but failure of
the Agent to give any such notice on the Drawing Date or in sufficient time to
enable any Bank to effect such payment on such date shall not relieve such Bank
from its obligation under this Section 2.9.3.3.

                    2.9.3.4   With respect to any unreimbursed drawing that is
not converted into Loans under the Base Rate Option to the Borrowers in whole or
in part as contemplated by Section 2.9.3.2, because of the Borrowers' failure to
satisfy the conditions set forth in Section 6.2 other than any notice
requirements or for any other reason, the Borrowers shall be deemed to have
incurred from the Agent a Letter of Credit Borrowing in the amount of such
drawing. Such Letter of Credit Borrowing shall be due and payable on demand
(together 

                                     -22-
<PAGE>
 
with interest) and shall bear interest at the rate per annum applicable to the
Revolving Credit Loans under the Base Rate Option. Each Bank's payment to the
Agent pursuant to Section 2.9.3.3 shall be deemed to be a payment in respect of
its participation in such Letter of Credit Borrowing and shall constitute a
Participation Advance from such Bank in satisfaction of its participation
obligation under this Section 2.9.3.

               2.9.4     Repayment of Participation Advances.
                         ----------------------------------- 

                    2.9.4.1   Upon (and only upon) receipt by the Agent for its
account of immediately available funds from the Borrowers (i) in reimbursement
of any payment made by the Agent under the Letter of Credit with respect to
which any Bank has made a Participation Advance to the Agent, or (ii) in payment
of interest on such a payment made by the Agent under such a Letter of Credit,
the Agent will pay to each Bank, in the same funds as those received by the
Agent, the amount of such Bank's Ratable Share of such funds, except the Agent
shall retain the amount of the Ratable Share of such funds of any Bank that did
not make a Participation Advance in respect of such payment by Agent.

                    2.9.4.2   If the Agent is required at any time to return to
any Loan Party, or to a trustee, receiver, liquidator, custodian, or any
official in any Insolvency Proceeding, any portion of the payments made by any
Loan Party to the Agent pursuant to Section 2.9.4.1 in reimbursement of a
payment made under the Letter of Credit or interest or fee thereon, each Bank
shall, on demand of the Agent, forthwith return to the Agent the amount of its
Ratable Share of any amounts so returned by the Agent plus interest thereon from
the date such demand is made to the date such amounts are returned by such Bank
to the Agent, at a rate per annum equal to the Federal Funds Effective Rate in
effect from time to time.

               2.9.5     Documentation.
                         ------------- 

               Each Loan Party agrees to be bound by the terms of the Agent's
application and agreement for letters of credit. In the event of a conflict
between such application or agreement and this Agreement, this Agreement shall
govern. It is understood and agreed that, except in the case of gross negligence
or willful misconduct, the Agent shall not be liable for any error, negligence
and/or mistakes, whether of omission or commission, in following any Loan
Party's instructions or those contained in the Letters of Credit or any
modifications, amendments or supplements thereto.

               2.9.6     Determinations to Honor Drawing Requests.
                         ---------------------------------------- 

               In determining whether to honor any request for drawing under any
Letter of Credit by the beneficiary thereof, the Agent shall be responsible only
to determine that the documents and certificates required to be delivered under
such Letter of Credit have been delivered and that they comply on their face
with the requirements of such Letter of Credit.

the Borrowers to reimburse the Agent upon a draw under a Letter of Credit, shall

accordance with the terms of this Section 2.9 under all circumstances, including
the following circumstances:

Person to comply with the conditions set forth in Section 2.1, 2.5, 2.6 or 6.2
or as otherwise set forth in this Agreement for the making of a Loan, it being
acknowledged that such conditions are not required for the making of a Loan
under Section 2.9.3;

                         (iii)   any lack of validity or enforceability of any
Letter of Credit;

                         (iv)    the existence of any claim, set-off, defense or
other right which any Loan Party or any Bank may have at any time against a
beneficiary or any transferee of any Letter of Credit (or any Persons for whom
any such transferee may be acting), the Agent or any Bank or any other Person
or, whether in connection with this Agreement, the transactions contemplated
herein or any unrelated transaction (including any underlying transaction
between any Loan Party or Subsidiaries of a Loan Party and the beneficiary for
which any Letter of Credit was procured);

                         (v)     any draft, demand, certificate or other

properties, assets, condition (financial or otherwise) or prospects of any Loan

Proceeding with respect to any Loan Party;

passed or this Agreement or the Revolving Credit Commitments hereunder shall
have been terminated; and

                         (xii)   any other circumstance or happening whatsoever,

               2.9.8     Indemnity.
                         --------- 

               In addition to amounts payable as provided in Section 9.5, the
Borrowers hereby agree jointly and severally to protect, indemnify, pay and save
harmless the Agent from and against any and all claims, demands, liabilities,
damages, losses, costs, charges and expenses (including reasonable fees,
expenses and disbursements of counsel which the Agent may incur or be subject to
as a consequence, direct or indirect, of (i) the issuance of any Letter of
Credit, other than as a result of (A) the gross negligence or willful misconduct
of the Agent as determined by a final judgment of a court of competent
jurisdiction or (B) subject to the following clause (ii), the wrongful dishonor
by the Agent of a proper demand for payment made under any Letter of Credit, or
(ii) the failure of the Agent to honor a drawing under any such Letter of Credit
as a result of any act or omission, whether rightful or wrongful, of any present
or future de jure or de facto government or governmental authority (all such
acts or omissions herein called "Governmental Acts").

               2.9.9     Liability for Acts and Omissions.
                         -------------------------------- 

               As between any Loan Party and the Agent, such Loan Party assumes
all risks of the acts and omissions of, or misuse of the Letters of Credit by,
the respective beneficiaries of such Letters of Credit. In furtherance and not
in limitation of the foregoing, the Agent shall, absent gross negligence or
willful misconduct, not be responsible for: (i) the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in
connection with the application for an issuance of any such Letter of Credit,
even if it should in fact prove to be in any or all respects invalid,
insufficient, inaccurate, fraudulent or forged (even if the Agent shall have
been notified thereof); (ii) the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any such Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) the
failure of the beneficiary of any such Letter of Credit, or any other party to
which such Letter of Credit may be transferred, to comply fully with any
conditions

Loan Party against any beneficiary of such Letter of Credit, or any such
transferee, or any dispute between or among any Loan Party and any beneficiary
of any Letter of Credit or any such transferee; (iv) errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail,
cable, telegraph, telex or otherwise, whether or not they be in cipher; (v)
errors in interpretation of technical terms; (vi) any loss or delay in the
transmission or otherwise of any document required in order to make a drawing
under any such Letter of Credit or of the proceeds thereof; (vii) the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of any drawing under such Letter of Credit; or (viii) any consequences arising
from causes beyond the control of the Agent, including any Governmental Acts,
and none of the above shall affect or impair, or prevent the vesting of, any of
the Agent's rights or powers hereunder.

               In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by the Agent
under or in connection with the Letters of Credit issued by it or any documents
and certificates delivered thereunder, if taken or omitted in good faith, shall
not put the Agent under any resulting liability to any Borrower or any Bank.

               Upon or promptly after delivery by Option Care, Inc. of the
annual financial statements to be provided under Section 7.3.3 for the fiscal
year ending December 31, 1997, the Borrowers may request a single one-year
extension of the Expiration Date by written notice to the Banks, and the Banks
agree to respond to the Borrower's request for an extension by June 30, 1998;
provided, however, that the failure of any Bank to respond within such time
period shall not in any manner constitute an agreement by such Bank to extend
the Expiration Date. If all Banks elect to extend, the Expiration Date shall be
extended for a period of one year. If one or more Banks decline to extend or do
not respond to Borrowers' request, the provisions of Section 2.10.2 shall apply.

               2.10.2    Approval by Required Banks.
                         -------------------------- 

               In the event that one or more Banks do not agree to extend the
Expiration Date or do not respond to Borrowers' request for an extension within
the time required under Section 2.10.1 (each a "Bank to be Replaced"), but the
Required Banks agree to such extension within such time then the Banks which
have agreed to such extension within the time required under Section 2.10.1
(each an "Extending Bank") may, with the prior written approval of the Borrowers
and the Agent, arrange to have one or more other banks (each an "Assignee Bank")
purchase all of the outstanding Loans, if any, of the Bank to be Replaced and
succeed to and assume the Revolving Credit Commitments and all other rights,
interests and obligations of the Bank to be Replaced under this Agreement and
the other Loan Documents. Any such purchase and assumption shall be (1) pursuant
to an Assignment and Assumption Agreement, (2) subject to and in accordance with
Section 10.11, and (3) effective on the last day of the Interest Period if 

                                     -26-

any Loans are outstanding under the Euro-Rate Option. The Borrowers shall pay
all amounts due and payable to the Bank to be Replaced on the effective date of
such Assignment and Assumption Agreement. In the event that the Agent shall
become a Bank to be Replaced, the provisions of this Section 2.10 shall be
subject to Section 10.14.


                              3.   INTEREST RATES
                                   --------------
                                        
          3.1  Interest Rate Options.
               --------------------- 

          The Borrowers shall pay interest in respect of the outstanding unpaid
principal amount of the Loans as selected by it from the Base Rate Option or
Euro-Rate Option set forth below applicable to the Loans, it being understood
that, subject to the provisions of this Agreement, the Borrowers may select
different Interest Rate Options and different Interest Periods to apply
simultaneously to the Loans comprising different Borrowing Tranches and may
convert to or renew one or more Interest Rate Options with respect to all or any
portion of the Loans comprising any Borrowing Tranche, provided that there shall
                                                       --------                 
not be at any one time outstanding more than four (4) Borrowing Tranches in the
aggregate among all of the Loans accruing interest at a Euro-Rate Option.  If at
any time the designated rate applicable to any Loan made by any Bank exceeds
such Bank's highest lawful rate, the rate of interest on such Bank's Loan shall
be limited to such Bank's highest lawful rate.

               3.1.1     Revolving Credit Interest Rate Options.
                         --------------------------------------

               The Borrowers shall have the right to select from the following
Interest Rate Options applicable to the Revolving Credit Loans:

                         (i)     Base Rate Option:  A fluctuating rate per 
                                 ----------------       
annum (computed on the basis of a year of 365 or 366 days, as the case may be,
and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such
interest rate to change automatically from time to time effective as of the
effective date of each change in the Base Rate; or

                         (ii)    Euro-Rate Option:  A rate per annum (computed 
                                 ----------------    
on the basis of a year of 360 days and actual days elapsed) equal to the Euro-
Rate plus the Applicable Margin.

               3.1.2     Rate Quotations.
                         --------------- 

               The Borrowers may call the Agent on or before the date on which a
Loan Request is to be delivered to receive an indication of the rates then in
effect, but it is acknowledged that such projection shall not be binding on the
Agent or the Banks nor affect the rate of interest which thereafter is actually
in effect when the election is made.

          3.2  Interest Periods.
               ---------------- 

          At any time when any Borrower shall select, convert to or renew a 
Euro-Rate Option, that Borrower shall notify the Agent thereof at least three
(3) Business Days prior to the effective date of such Euro-Rate Option by
delivering a Loan Request. The notice shall specify an interest period (the
"Interest Period") during which such Interest Rate Option shall apply, such
Interest Period to be (i) one Month if Borrowers select the Euro-Rate Option
during the Syndication Period and (ii) one, two, three or six Months in the
event Borrowers select the Euro-Rate Option after the Syndication Period has
ended. Notwithstanding the preceding sentence, the following provisions shall
apply to any selection of, renewal of, or conversion to a Euro-Rate Option:

               3.2.1     Ending Date and Business Day.
                         ---------------------------- 

               any Interest Period which would otherwise end on a date which is
not a Business Day shall be extended to the next succeeding Business Day unless
such Business Day falls in the next calendar month, in which case such Interest
Period shall end on the next preceding Business Day;

               3.2.2     Amount of Borrowing Tranche.
                         --------------------------- 

               each Borrowing Tranche of Euro-Rate Loans shall be in the minimum
amount of $1,000,000 and in integral multiples of $100,000;

               3.2.3     Termination Before Expiration Date.
                         ---------------------------------- 

               the Borrowers shall not select, convert to or renew an Interest
Period for any portion of the Loans that would end after the Expiration Date;
and

               3.2.4     Renewals.
                         -------- 

               in the case of the renewal of a Euro-Rate Option at the end of an
Interest Period, the first day of the new Interest Period shall be the last day
of the preceding Interest Period, without duplication in payment of interest for
such day.

          3.3  Interest After Default.
               ---------------------- 

          To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time such Event of Default shall have been cured or
waived:

               3.3.1     Letter of Credit Fees, Interest Rate.
                         ------------------------------------

          the Letter of Credit Fees and the rate of interest for each Loan
otherwise applicable pursuant to Section 2.9.2 or Section 3.1, respectively,
shall be increased by 2.0% per annum; and

                                     -28-
<PAGE>
 
               3.3.2     Other Obligations.
                         ----------------- 

               each other Obligation hereunder if not paid when due shall bear
interest at a rate per annum equal to the sum of the rate of interest applicable
under the Revolving Credit Base Rate Option plus an additional 2% per annum from
the time such Obligation becomes due and payable and until it is paid in full.

               3.3.3     Acknowledgment.
                         -------------- 

               The Borrowers acknowledge that the increase in rates referred to
in this Section 3.3 reflects, among other things, the fact that such Loans or
other amounts have become a substantially greater risk given their default
status and that the Banks are entitled to additional compensation for such risk;
and all such interest shall be payable by Borrowers upon demand by Agent.

          3.4  Euro-Rate Unascertainable.
               ------------------------- 

               3.4.1     Unascertainable.
                         --------------- 

               If on any date on which a Euro-Rate would otherwise be
determined, the Agent shall have determined that:

                         (i)     adequate and reasonable means do not exist for
ascertaining such Euro-Rate, or

                         (ii)    a contingency has occurred which materially and
adversely affects the secondary market for negotiable certificates of deposit
maintained by dealers of recognized standing relating to the London interbank
eurodollar market relating to the Euro-Rate, the Agent shall have the rights
specified in Section 3.4.3.

               3.4.2     Illegality; Increased Costs; Deposits Not Available.
                         ---------------------------------------------------

               If at any time any Bank shall have determined that:

                         (i)     the making, maintenance or funding of any Loan
to which a Euro-Rate Option applies has been made impracticable or unlawful by
compliance by such Bank in good faith with any Law or any interpretation or
application thereof by any Official Body or with any request or directive of any
such Official Body (whether or not having the force of Law), or

                         (ii)    after making all reasonable efforts, deposits
of the relevant amount in Dollars for the relevant Interest Period for a Loan to
which a Euro-Rate Option applies, respectively, are not available to such Bank
at the effective cost of funding a proposed Loan in the London interbank market,
then the Agent shall have the rights specified in Section 3.4.3.

               3.4.3     Agent's and Bank's Rights.
                         ------------------------- 

               In the case of any event specified in Section 3.4.1 above, the
Agent shall promptly so notify the Banks and the Borrowers thereof, and in the
case of an event specified in Section 3.4.2 above, such Bank shall promptly so
notify the Agent and endorse a certificate to such notice as to the specific
circumstances of such notice, and the Agent shall promptly send copies of such
notice and certificate to the other Banks and the Borrowers. Upon such date as
shall be specified in such notice (which shall not be earlier than the date such
notice is given), the obligation of (A) the Banks, in the case of such notice
given by the Agent, or (B) such Bank, in the case of such notice given by such
Bank, to allow the Borrowers to select, convert to or renew a Euro-Rate Option
shall be suspended until the Agent shall have later notified the Borrowers, or
such Bank shall have later notified the Agent, of the Agent's or such Bank's, as
the case may be, determination that the circumstances giving rise to such
previous determination no longer exist which notice shall be sent within two
Business Days after such determination. If at any time the Agent makes a
determination under Section 3.4.1 and a Borrower has previously notified the
Agent of its selection of, conversion to or renewal of a Euro-Rate Option and
such Interest Rate Option has not yet gone into effect, such notification shall
be deemed to provide for selection of, conversion to or renewal of the Base Rate
Option otherwise available with respect to such Loans. If any Bank notifies the
Agent of a determination under Section 3.4.2, the Borrowers shall, subject to
the Borrowers' indemnification Obligations under Section 4.5.2, as to any Loan
of the Bank to which a Euro-Rate Option applies, on the date specified in such
notice either convert such Loan to the Base Rate Option otherwise available with
respect to such Loan or prepay such Loan in accordance with Section 4.4. Absent
due notice from the Borrowers of conversion or prepayment, such Loan shall
automatically be converted to the Base Rate Option otherwise available with
respect to such Loan upon such specified date.

          3.5  Selection of Interest Rate Options.
               ---------------------------------- 

          If the Borrowers fail to select a new Interest Period to apply to any
Borrowing Tranche of Loans under the Euro-Rate Option at the expiration of an
existing Interest Period applicable to such Borrowing Tranche in accordance with
the provisions of Section 3.2, the Borrowers shall be deemed to have converted
such Borrowing Tranche to the Revolving Credit Base Rate Option commencing upon
the last day of the existing Interest Period.

nature, and an action therefor shall immediately accrue. Such payments shall be
made to the Agent at the Principal Office for the ratable accounts of the Banks
with respect to the Loans in U.S. Dollars and in immediately available funds,
and the Agent shall promptly distribute such amounts to the Banks in immediately
available funds, provided that in the event payments are received by 1:00 p.m.,
                 --------                                                      
Pittsburgh time, by the Agent with respect to the Loans and such payments are
not distributed to the Banks on the same day received by the Agent, the Agent
shall pay the Banks the Federal Funds Effective Rate with respect to the amount
of such payments for each day held by the Agent and not distributed to the
Banks. The Agent's and each Bank's statement of account, ledger or other
relevant record shall, in the absence of manifest error, be conclusive as the
statement of the amount of principal of and interest on the Loans and other
amounts owing under this Agreement and shall be deemed an "account stated."

          4.2  Pro Rata Treatment of Banks.
               --------------------------- 

          Each borrowing shall be allocated to each Bank according to its

specified in Section 3.4 (Euro-Rate Unascertainable), 4.4.3 (Voluntary
Prepayments) or 4.4 (Additional Compensation in Certain Circumstances)) be made
in proportion to the applicable Loans outstanding from each Bank and, if no such
Loans are then outstanding, in proportion to the Ratable Share of each Bank.

          4.3  Interest Payment Dates.
               ---------------------- 

          Interest on Loans to which the Base Rate Option applies shall be due
and payable in arrears on the first Business Day of each January, April, July
and September after the date hereof and on the Expiration Date or upon
acceleration of the Notes. Interest on Loans to which the Euro-Rate Option
applies shall be due and payable on the last day of each Interest Period for
those Loans and, if such Interest Period is longer than three (3) Months, also
on the 90th day of such Interest Period. Interest on the principal amount of
each Loan or other monetary Obligation shall be due and payable on demand after
such principal amount or other monetary Obligation becomes due and payable
(whether on the stated maturity date, upon acceleration or otherwise).

          4.4  Prepayments.
               ----------- 

               4.4.1     Right to Prepay.
                         --------------- 

               The Borrowers shall have the right at their option from time to
time to prepay the Loans in whole or part without premium or penalty (except as
provided in Section 4.4.3 below or in Section 4.5):

                                     -31-
<PAGE>
 
                         (i)     at any time with respect to any Loan to which
the Base Rate Option applies,

                         (ii)    on the last day of the applicable Interest
Period with respect to Loans to which a Euro-Rate Option applies,

                         (iii)   on the date specified in a notice by any Bank
pursuant to Section 3.4 (Euro-Rate Unascertainable) with respect to any Loan to
which a Euro-Rate Option applies.

               Whenever the Borrowers desire to prepay any part of the Loans,
they shall provide a prepayment notice to the Agent at least one (1) Business
Day prior to the date of prepayment of Loans setting forth the following
information:

               (x)  the date, which shall be a Business Day, on which the
          proposed prepayment is to be made;

               (y)  a statement indicating the application of the prepayment
          among Borrowing Tranches; and

               (z)  the total principal amount of such prepayment, which shall
          not be less than $100,000.

               All prepayment notices shall be irrevocable. The principal amount
of the Loans for which a prepayment notice is given, together with interest on
such principal amount except with respect to Loans to which the Base Rate Option
applies, shall be due and payable on the date specified in such prepayment
notice as the date on which the proposed prepayment is to be made. Except as
provided in Section 3.4.3, if the Borrowers prepay a Loan but fail to specify
the applicable Borrowing Tranche which the Borrowers are prepaying, the
prepayment shall be applied first to Loans to which the Base Rate Option applies
and then to Loans to which the Euro-Rate Option applies. Any prepayment
hereunder shall be subject to the Borrowers' Obligation to indemnify and
compensate the Banks under Section 4.5.2.

               The Borrowers may direct the Banks at any time to permanently
reduce their Revolving Credit Commitments; provided that no reduction shall
                                           --------                
bring the Revolving Credit Commitment below the sum of Loans outstanding and the
face amount of all Letters of Credit outstanding.

Commitment.
- ----------

               Within five (5) Business Days of any sale of assets with book
value of more than $500,000 authorized by Section 7.2.7, the Borrowers shall
make a mandatory prepayment of the Loans equal to the proceeds of such sale net
of costs of sale. All prepayments pursuant to this Section 4.4.2 shall
permanently reduce the Revolving Credit Commitment with the exception of

                                     -32-
<PAGE>
 
prepayments resulting from sales (i) which are of assets with book values in the
aggregate less than $500,000 or (ii) if within six months of such sales the Loan
Parties have invested or reinvested an amount equivalent to the proceeds of sale
in assets of at least comparable value. In no event will assets be sold for
after-tax proceeds exceeding $3,000,000 in the aggregate.

               4.4.3     Replacement of a Bank.
                         --------------------- 

               In the event any Bank (i) gives notice under Section 3.4 or
Section 4.5.1, (ii) does not fund Revolving Credit Loans because the making of
such Loans would contravene any Law applicable to such Bank, or (iii) becomes
subject to the control of an Official Body (other than normal and customary
supervision), then the Borrowers shall have the right at their option, with the
consent of the Agent, which shall not be unreasonably withheld, to prepay the
Loans of such Bank in whole, together with all interest accrued thereon, and
terminate such Bank's Revolving Credit Commitment within ninety (90) days after
(w) receipt of such Bank's notice under Section 3.4 or 4.5.1, (x) the date such
Bank has failed to fund Revolving Credit Loans because the making of such Loans
would contravene Law applicable to such Bank, (y) the date of obtaining the
consent which such Bank has not approved, or (z) the date such Bank became
subject to the control of an Official Body, as applicable; provided that the
                                                           -------- 
Borrowers shall also pay to such Bank at the time of such prepayment any amounts
required under Section 4.5 and any accrued interest due on such amount and any
related fees; provided, however, that the Revolving Credit Commitment of such
              -------- 
Bank shall be provided by one or more of the remaining Banks or a replacement
bank acceptable to the Agent; provided, further, the remaining Banks shall have
                              --------                      
no obligation hereunder to increase their Revolving Credit Commitments.
Notwithstanding the foregoing, the Agent may only be replaced subject to the
requirements of Section 9.1.4 and provided that all Letters of Credit have
                                  --------

               4.4.4     Change of Lending Office
                         ------------------------

               Each Bank agrees that upon the occurrence of any event giving
rise to increased costs or other special payments under Section 3.4.2
(Illegality, etc.) or 4.5.1 (Increased Costs, etc.) with respect to such Bank,
it will if requested by the Borrowers use reasonable efforts (subject to overall
policy considerations of such Bank) to designate another lending office for any
Loans or Letters of Credit affected by such event, provided that such
                                                   --------    
designation is made on such terms that such Bank and its lending office suffer
no economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of such Section. Nothing
is this Section 4.4.3 shall affect or postpone any of the Obligations of the
Borrowers or any other Loan Party or the rights of the Agent or any Bank
provided in this Agreement.

any Official Body charged with the interpretation or administration thereof
enacted or made after the date of this Agreement or compliance with any request
or directive (whether or not having the force of Law) of any central bank or
other Official Body made after the date of this Agreement:

                         (i)     subjects any Bank to any tax or changes the
basis of taxation with respect to this Agreement, the Notes, the Loans or
payments by the Borrowers of principal, interest, Commitment Fees, or other
amounts due from the Borrowers hereunder or under the Notes (except for taxes on
the overall net income or gross receipts of such Bank),

                         (ii)    imposes, modifies or deems applicable any
reserve, special deposit or similar requirement against credits or commitments
to extend credit extended by, or assets (funded or contingent) of, deposits with
or for the account of, or other acquisitions of funds by, any Bank, or

                         (iii)   imposes, modifies or deems applicable any
capital adequacy or similar requirement (A) against assets (funded or
contingent) of, or letters of credit, other credits or commitments to extend
credit extended by, any Bank, or (B) otherwise applicable to the obligations of
any Bank under this Agreement, and the result of any of the foregoing is to
increase the cost to, reduce the income receivable by, or impose any expense
(including loss of margin) upon any Bank with respect to this Agreement, the
Notes or the making, maintenance or funding of any part of the Loans (or, in the
case of any capital adequacy or similar requirement, to have the effect of
reducing the rate of return on any Bank's capital, taking into consideration
such Bank's customary policies with respect to capital adequacy) by an amount
which such Bank in its sole discretion deems to be material, such Bank shall
from time to time notify the Borrowers and the Agent of the amount determined in
good faith (using any averaging and attribution methods employed in good faith
including allocation to the Borrowers of pro rated amounts ) by such Bank to be
necessary to compensate such Bank for such increase in cost, reduction of
income, additional expense or reduced rate of return. The Banks will use
reasonable efforts to avoid such increase in costs, reduction of income,
additional expense or reduced rate of return . Notice shall set forth in
reasonable detail the basis for such determination. Such amount shall be due and
payable by the Borrower to such Bank thirty (30) Business Days after such notice
is given. If any amounts paid by the Loan Parties pursuant to this Section 4.5.1
are later refunded to a Bank, the Bank will remit the refund to the Loan
Parties.

all liabilities, losses or expenses (including loss of margin, any loss or
expense incurred in liquidating or employing deposits from third parties and any
loss or expense incurred in connection with funds acquired by a Bank to fund or
maintain Loans subject to a Euro-Rate Option) which such Bank sustains or incurs
as a consequence of any

any Loan to which a Euro-Rate Option applies on a day other than the last day of

mandatory, voluntary or automatic and whether or not such payment or prepayment
is then due),

                         (ii)    attempt by any Borrower to revoke (expressly,
by later inconsistent notices or otherwise) in whole or part any Loan Requests
under Section 2.5 or Section 3.2 or notice relating to prepayments under Section
4.4, or

                         (iii)   default by any Borrower in the performance or
observance of any covenant or condition contained in this Agreement or any other
Loan Document, including any failure of the Borrower to pay when due (by
acceleration or otherwise) any principal, interest, Commitment Fee or any other
amount due hereunder.

If any Bank sustains or incurs any such loss or expense, it shall from time to
time notify the Borrowers of the amount determined in good faith by such Bank
(which determination may include such assumptions, allocations of costs and
expenses and averaging or attribution methods as such Bank shall deem
reasonable) to be necessary to indemnify and compensate such Bank for such loss
or expense. Such notice shall set forth in reasonable detail the basis for such
determination and shall be binding absent manifest error. Such amount shall be
due and payable by the Borrowers to such Bank ten (10) Business Days after such

               Each Loan Party shall, and shall cause each of its Subsidiaries
to, insure its properties and assets against loss or damage by fire and such
other insurable hazards as such assets are commonly insured (including fire,
extended coverage, property damage, workers' compensation, public liability and
business interruption insurance) and against other risks (including errors and
omissions) in such amounts as similar properties and assets are insured by
prudent companies in similar circumstances carrying on similar businesses, and
with reputable and financially sound insurers, including self-insurance to the
extent customary, all as reasonably determined by the Agent. At the request of
the Agent, the Loan Parties shall deliver to the Agent and each of the Banks (x)

and (y) from time to time a summary schedule indicating all insurance then in
force with respect to each of the Loan Parties. Such policies of insurance shall
contain special endorsements, in form and substance acceptable to the Agent,
which shall (i) specify the Agent as an additional insured, mortgagee and lender
loss payee as its interests may appear, with the understanding that any
obligation imposed upon the insured (including the liability to pay premiums)
shall be the sole obligation of the applicable Loan Parties and not that of the
insured, (ii) provide that no cancellation of such policies for any reason
(including non-payment of premium) nor any change therein shall be effective
until at least thirty (30) days after receipt by the Agent of written notice of
such cancellation or change, (iii) be primary without right of contribution of
any other insurance carried by or on behalf of any additional insureds with
respect to their respective interests in the Collateral, and (iv) provide that
inasmuch as the policy covers more than one insured, all terms, conditions,
insuring agreements and endorsements (except limits of liability) shall operate
as if there were a separate policy covering each insured. If a Loan Party
notifies its insurance agent or carrier of a claim in excess of $500,000 for any

          9.1   Appointment.
                ----------- 

          Each Bank hereby irrevocably designates, appoints and authorizes PNC
Bank to act as Agent for such Bank under this Agreement and to execute and
deliver or accept on behalf of each of the Banks the other Loan Documents.  Each
Bank hereby irrevocably authorizes, and each holder of any Note by the
acceptance of a Note shall be deemed irrevocably to authorize, the Agent to take
such action on its behalf under the provisions of this Agreement and the other
Loan Documents and any other instruments and agreements referred to herein, and
to exercise such powers and to perform such duties hereunder as are specifically
delegated to or required of the Agent by the terms hereof, together with such
powers as are reasonably incidental thereto.  PNC Bank agrees to act as the
Agent on behalf of the Banks to the extent provided in this Agreement.

          9.2   Delegation of Duties.
                -------------------- 

          The Agent may perform any of its duties hereunder by or through agents
or employees (provided such delegation does not constitute a relinquishment of
              --------                                                        
its duties as Agent) and, subject to Sections 9.5 and 9.6, shall be entitled to
engage and pay for the advice or services of any attorneys, accountants or other
experts concerning all matters pertaining to its duties hereunder and to rely
upon any advice so obtained.

          9.3   Nature of Duties; Independent Credit Investigation.
                -------------------------------------------------- 

          The Agent shall have no duties or responsibilities except those
expressly set forth in this Agreement and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities shall be read into this
Agreement or otherwise exist.  The duties of the Agent shall be mechanical and
administrative in nature; the Agent shall not have by reason of this Agreement a
fiduciary or trust relationship in respect of any Bank; and nothing in this
Agreement, expressed or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement except as
expressly set forth herein.  Without limiting the generality of the foregoing,
the use of the term "agent" in this Agreement with reference to the Agent is not
intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable Law.  Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties.  Each
Bank expressly acknowledges (i) that the Agent has not made any representations
or warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of any of the Loan Parties, shall be deemed to constitute
any representation or warranty by the Agent to any Bank; (ii) that it has made
and will continue to make, without reliance upon the Agent, its own independent
investigation of the financial condition and affairs and its own appraisal of
the creditworthiness of each of the Loan Parties in connection with this
Agreement and the making and continuance of the Loans hereunder; and (iii)
except as expressly provided herein, that the Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Bank
with any credit or other information with respect thereto, 

                                     -72-

whether coming into its possession before the making of any Loan or at any time
or times thereafter.

          9.4   Actions in Discretion of Agent; Instructions from the Banks.
                ----------------------------------------------------------- 

          The Agent agrees, upon the written request of the Required Banks, to
take or refrain from taking any action of the type specified as being within the
Agent's rights, powers or discretion herein, provided that the Agent shall not
                                             --------                         
be required to take any action which exposes the Agent to personal liability or
which is contrary to this Agreement or any other Loan Document or applicable
Law.  In the absence of a request by the Required Banks, the Agent shall have
authority, in its sole discretion, to take or not to take any such action,
unless this Agreement specifically requires the consent of the Required Banks or
all of the Banks.  Any action taken or failure to act pursuant to such
instructions or discretion shall be binding on the Banks, subject to Section
9.6.  Subject to the provisions of Section 9.6, no Bank shall have any right of
action whatsoever against the Agent as a result of the Agent acting or
refraining from acting hereunder in accordance with the instructions of the
Required Banks, or in the absence of such instructions, in the absolute
discretion of the Agent.

          9.5   Reimbursement and Indemnification of Agent by the Borrower.
                ---------------------------------------------------------- 

          The Borrowers jointly and severally and unconditionally agree to pay
or reimburse the Agent and hold the Agent harmless against (a) liability for the
payment of all reasonable out-of-pocket costs, expenses and disbursements,
including fees and expenses of counsel (including the allocated costs of staff
counsel), appraisers and environmental consultants, incurred by the Agent (i) in
connection with the development, negotiation, preparation, printing, execution,
syndication, interpretation and performance of this Agreement and the other Loan
Documents, (ii) relating to any requested amendments, waivers or consents
pursuant to the provisions hereof, (iii) in connection with the enforcement of
this Agreement or any other Loan Document or collection of amounts due hereunder
or thereunder or the proof and allowability of any claim arising under this
Agreement or any other Loan Document, whether in bankruptcy or receivership
proceedings or otherwise, and (iv) in any workout or restructuring or in
connection with the protection, preservation, exercise or enforcement of any of
the terms hereof or of any rights hereunder or under any other Loan Document or
in connection with any foreclosure, collection or bankruptcy proceedings, and
(b) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by the Agent
hereunder or thereunder, provided that the Borrowers shall not be liable for any
                         --------                                               
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements if the same results from the
Agent's gross negligence or willful misconduct, or if the Borrowers were not
given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense (except that the Borrowers shall remain liable
to the extent such failure to give notice does not result in a loss to the
Borrowers), or if the same results from a compromise or settlement agreement
entered into without the consent of the 

                                     -73-
<PAGE>
 
Borrowers, which shall not be unreasonably withheld. At a Loan Party's
reasonable request, an officer of the Loan Party may discuss initial budgets
developed by counsel for the Agent (as long as such counsel determines that no
privilege will be waived as a result of such discussions). Nothing in this
Section 9.5 prevents a Borrower from obtaining its own counsel and controlling
its own defense in any action.

          9.6   Exculpatory Provisions; Limitation of Liability.
                -----------------------------------------------

          Neither the Agent nor any of its directors, officers, employees,
agents, attorneys or Affiliates shall (a) be liable to any Bank for any action
taken or omitted to be taken by it or them hereunder, or in connection herewith
including pursuant to any Loan Document, unless caused by its or their own gross
negligence or willful misconduct, (b) be responsible in any manner to any of the
Banks for the effectiveness, enforceability, genuineness, validity or the due
execution of this Agreement or any other Loan Documents or for any recital,
representation, warranty, document, certificate, report or statement herein or
made or furnished under or in connection with this Agreement or any other Loan
Documents, or (c) be under any obligation to any of the Banks to ascertain or to
inquire as to the performance or observance of any of the terms, covenants or
conditions hereof or thereof on the part of the Loan Parties, or the financial
condition of the Loan Parties, or the existence or possible existence of any
Event of Default or Potential Default. No claim may be made by any of the Loan
Parties, any Bank, the Agent or any of their respective Subsidiaries against the
Agent, any Bank or any of their respective directors, officers, employees,
agents, attorneys or Affiliates, or any of them, for any special, indirect or
consequential damages or, to the fullest extent permitted by Law, for any
punitive damages in respect of any claim or cause of action (whether based on
contract, tort, statutory liability, or any other ground) based on, arising out
of or related to any Loan Document or the transactions contemplated hereby or
any act, omission or event occurring in connection therewith, including the
negotiation, documentation, administration or collection of the Loans, and each
of the Loan Parties, (for itself and on behalf of each of its Subsidiaries), the
Agent and each Bank hereby waive, releases and agree never to sue upon any claim
for any such damages, whether such claim now exists or hereafter arises and
whether or not it is now known or suspected to exist in its favor.  Each Bank
agrees that, except for notices, reports and other documents expressly required
to be furnished to the Banks by the Agent hereunder or given to the Agent for
the account of or with copies for the Banks, the Agent and each of its
directors, officers, employees, agents, attorneys or Affiliates shall not have
any duty or responsibility to provide any Bank with an credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of the Loan Parties which may come
into the possession of the Agent or any of its directors, officers, employees,

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

          Each Bank agrees to reimburse and indemnify the Agent (to the extent
not reimbursed by the Borrowers and without limiting the Obligation of the
Borrowers to do so) in proportion to its Ratable Share from and against all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements, including attorneys' fees and 

                                     -74-
<PAGE>
 
disbursements (including the allocated costs of staff counsel), and costs of
appraisers and environmental consultants, of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against the Agent, in its capacity as
such, in any way relating to or arising out of this Agreement or any other Loan
Documents or any action taken or omitted by the Agent hereunder or thereunder,
provided that no Bank shall be liable for any portion of such liabilities,
- --------     
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements (a) if the same results from the Agent's gross
negligence or willful misconduct, or (b) if such Bank was not given notice of
the subject claim and the opportunity to participate in the defense thereof, at
its expense (except that such Bank shall remain liable to the extent such
failure to give notice does not result in a loss to the Bank), or (c) if the
same results from a compromise and settlement agreement entered into without the
consent of such Bank, which shall not be unreasonably withheld. In addition,
each Bank agrees promptly upon demand to reimburse the Agent (to the extent not
reimbursed by the Borrowers and without limiting the Obligation of the Borrowers
to do so) in proportion to its Ratable Share for all amounts due and payable by
the Borrowers to the Agent in connection with the Agent's periodic audit of the
Loan Parties' books, records and business properties.

          9.8   Reliance by Agent.
                ----------------- 

          The Agent shall be entitled to rely upon any writing, telegram, telex
or teletype message, resolution, notice, consent, certificate, letter,
cablegram, statement, order or other document or conversation by telephone or
otherwise believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons, and upon the advice and opinions of
counsel and other professional advisers selected by the Agent.  The Agent shall
be fully justified in failing or refusing to take any action hereunder 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 or
continuing to take any such action.

          9.9   Notice of Default.
                ----------------- 

          The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Potential Default or Event of Default unless the Agent has
received written notice from a Bank or the Borrowers referring to this
Agreement, describing such Potential Default or Event of Default and stating
that such notice is a "notice of default."

          9.10  Notices.
                ------- 

          The Agent shall promptly send to each Bank a copy of all notices
received from the Borrowers pursuant to the provisions of this Agreement or the
other Loan Documents promptly upon receipt thereof.  The Agent shall promptly
notify the Borrowers and the other Banks of each change in the Base Rate and the
effective date thereof.

                                     -75-

          9.11  Banks in Their Individual Capacities.
                ------------------------------------ 

          With respect to its Revolving Credit Commitment, the Loans made by it,
and any other rights and powers given to it as a Bank hereunder or under any of
the other Loan Documents, the Agent shall have the same rights and powers
hereunder as any other Bank and may exercise the same as though it were not the
Agent, and the term "Banks" shall, unless the context otherwise indicates,
include the Agent in its individual capacity.  PNC Bank and its Affiliates and
each of the Banks and their respective Affiliates may, without liability to
account, except as prohibited herein, make loans to, accept deposits from,
discount drafts for, act as trustee under indentures of, and generally engage in
any kind of banking or trust business with, the Loan Parties and their
Affiliates, in the case of the Agent, as though it were not acting as Agent
hereunder and in the case of each Bank, as though such Bank were not a Bank
hereunder.  The Banks acknowledge that, pursuant to such activities, the Agent
or its Affiliates may (i) receive information regarding the Loan Parties
(including information that may be subject to confidentiality obligations in
favor of the Loan Parties) and acknowledge that the Agent shall be under no
obligation to provide such information to them, and (ii) accept fees and other
consideration from the Loan Parties for services in connection with this
Agreement and otherwise without having to account for the same to the Banks.

          9.12  Holders of Notes.
                ---------------- 

          The Agent may deem and treat any payee of any Note as the owner
thereof for all purposes hereof unless and until written notice of the
assignment or transfer thereof shall have been filed with the Agent.  Any
request, authority or consent of any Person who at the time of making such
request or giving such authority or consent is the holder of any Note shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any Note or Notes issued in exchange therefor.

          9.13  Equalization of Banks.
                --------------------- 

          The Banks and the holders of any participations in any Notes agree
among themselves that, with respect to all amounts received by any Bank or any
such holder for application on any Obligation hereunder or under any Note or
under any such participation, whether received by voluntary payment, by
realization upon security, by the exercise of the right of set-off or banker's
lien, by counterclaim or by any other non-pro rata source, equitable adjustment
will be made in the manner stated in the following sentence so that, in effect,
all such excess amounts will be shared ratably among the Banks and such holders
in proportion to their interests in payments under the Notes, except as
otherwise provided in Section 3.4.3, 4.4.3 or 4.5.  The Banks or any such holder
receiving any such amount shall purchase for cash from each of the other Banks
an interest in such Bank's Loans in such amount as shall result in a ratable
participation by the Banks and each such holder in the aggregate unpaid amount
under the Notes, provided that if all or any portion of such excess amount is
                 --------                                                    
thereafter recovered from the Bank or the holder making such purchase, such
purchase shall be rescinded and the purchase price 

                                     -76-
<PAGE>
 
restored to the extent of such recovery, together with interest or other
amounts, if any, required by law (including court order) to be paid by the Bank
or the holder making such purchase.

          9.14  Successor Agent.
                --------------- 

          The Agent (i) may resign as Agent or (ii) shall resign if such
resignation is requested by the Required Banks (if the Agent is a Bank, the
Agent's Loans and its Revolving Credit Commitment shall be considered in
determining whether the Required Banks have requested such resignation) or
required by Section 4.4.3, in either case of (i) or (ii) by giving not less than
thirty (30) days' prior written notice to the Borrowers.  If the Agent shall
resign under this Agreement, then either (a) the Required Banks shall appoint
from among the Banks a successor agent for the Banks, subject to the consent of
the Borrowers, such consent not to be unreasonably withheld, or (b) if a
successor agent shall not be so appointed and approved within the thirty (30)
day period following the Agent's notice to the Banks of its resignation, then
the Agent shall appoint, with the consent of the Borrowers, such consent not to
be unreasonably withheld, a successor agent who shall serve as Agent until such
time as the Required Banks appoint and the Borrowers consent to the appointment
of a successor agent.  Upon its appointment pursuant to either clause (a) or (b)
above, such successor agent shall succeed to the rights, powers and duties of
the Agent, and the term "Agent" shall mean such successor agent, effective upon
its appointment, and the former Agent's rights, powers and duties as Agent shall
be terminated without any other or further act or deed on the part of such
former Agent or any of the parties to this Agreement.  After the resignation of
any Agent hereunder, the provisions of this Section 9 shall inure to the
benefit of such former Agent and such former Agent shall not by reason of such
resignation be deemed to be released from liability for any actions taken or not
taken by it while it was an Agent under this Agreement.

          9.15  Agent's Fee.
                ----------- 

          The Borrowers shall pay to the Agent a nonrefundable fee (the "Agent's
Fee") under the terms of a letter (the "Agent's Letter") between Option Care,
Inc. and Agent, as amended from time to time.

          9.16  Availability of Funds.
                --------------------- 

          The Agent may assume that each Bank has made or will make the proceeds
of a Loan available to the Agent unless the Agent shall have been notified by
such Bank on or before the later of (1) the close of Business on the Business
Day preceding the Borrowing Date with respect to such Loan or (2) five hours
before the time on which the Agent actually funds the proceeds of such Loan to
the Borrowers (whether using its own funds pursuant to this Section 9.16 or
using proceeds deposited with the Agent by the Banks and whether such funding
occurs before or after the time on which Banks are required to deposit the
proceeds of such Loan with the Agent).  The Agent may, in reliance upon such
assumption (but shall not be required to), make available to the Borrowers a
corresponding amount.  If such corresponding amount is not in fact made
available to the Agent by such Bank, the Agent shall be entitled to recover such
amount 

                                     -77-
<PAGE>
 
on demand from such Bank (or, if such Bank fails to pay such amount forthwith
upon such demand from the Borrower) together with interest thereon, in respect
of each day during the period commencing on the date such amount was made
available to the Borrowers and ending on the date the Agent recovers such
amount, at a rate per annum equal to the Federal Funds Rate.

          9.17  Calculations.
                ------------ 

          In the absence of gross negligence or willful misconduct, the Agent
shall not be liable for any error in computing the amount payable to any Bank
whether in respect of the Loans, fees or any other amounts due to the Banks
under this Agreement.  In the event an error in computing any amount payable to
any Bank is made, the Agent, the Borrowers and each affected Bank shall,
forthwith upon discovery of such error, make such adjustments as shall be
required to correct such error, and any compensation therefor will be calculated
at the Federal Funds Effective Rate.

          9.18  Beneficiaries.
                ------------- 

          Except as expressly provided herein, the provisions of this Section 9
are solely for the benefit of the Agent and the Banks, and the Loan Parties
shall not have any rights to rely on or enforce any of the provisions hereof.
In performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be deemed to have
assumed any obligation toward or relationship of agency or trust with or for any
of the Loan Parties.


                              10.   MISCELLANEOUS

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

provision of this Agreement or any other Loan Document or the rights of the
Banks or the Loan Parties hereunder or thereunder, or may grant written waivers
or consents to a departure from the due performance of the Obligations of the
Loan Parties hereunder or thereunder.  Any such agreement, waiver or consent

interest of any Loan, the Commitment Fee or any other fee payable to any Bank;

                10.1.3    Release of Collateral or Guarantor.
                          ----------------------------------

          No course of dealing and no delay or failure of the Agent or any Bank

Agreement or any other Loan Document shall affect any other or future exercise
thereof or operate as a waiver thereof, nor shall any single or partial exercise
thereof or any abandonment or discontinuance of steps to enforce such a right,
power, remedy or privilege preclude any further exercise thereof or of any other
right, power, remedy or privilege.  The rights and remedies of the Agent and the
Banks under this Agreement and any other Loan Documents are cumulative and not
exclusive of any rights or remedies which they would otherwise have.  Any
waiver, permit, consent or approval of any kind or character on the part of any
Bank of any breach or default under this Agreement or any such waiver of any
provision or condition of this Agreement must be in writing and shall be

          10.3  Reimbursement and Indemnification of Banks by the Borrower;
                -----------------------------------------------------------
Taxes.
- -----

          The Borrowers agree within thirty (30) calendar days after demand to
pay or reimburse to each Bank (other than the Agent, as to which the Borrowers'
Obligations are set forth in Section 9.5) and to save such Bank harmless against
(i) liability for the payment of all reasonable out-of-pocket costs, expenses
and disbursements (including fees and expenses of counsel for each Bank except
with respect to (a) and (b) below), incurred by such Bank (a) in connection with
the interpretation of this Agreement, and other instruments and documents to be
delivered hereunder, (b) relating to any amendments, waivers or consents
pursuant to the provisions hereof, (c) in connection with the enforcement of
this Agreement or any other Loan Document, or collection of amounts due
hereunder or thereunder or the proof and allowability of any claim arising under
this Agreement or any other Loan Document, whether in bankruptcy or receivership
proceedings or otherwise, and (d) in any workout or restructuring or in
connection with the protection, preservation, exercise or enforcement of any of
the terms hereof or of any rights hereunder or under any other Loan Document or
in connection with any foreclosure, collection or bankruptcy proceedings, or
(ii) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against such Bank,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by such Bank
hereunder or thereunder, provided that the Borrowers shall not be liable for any
                         --------                                               
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (A) if the same results from
such Bank's gross negligence or willful misconduct, or (B) if the Borrowers were
not given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense (except that the Borrowers shall remain liable
to the extent such failure to give notice does not result in a loss to the
Borrowers), or (C) if the same results from a compromise or settlement agreement
entered into without the consent of the Borrowers, which shall not be
unreasonably withheld.  The Banks will attempt to minimize the fees and expenses
of legal counsel for the Banks which are subject to reimbursement by the
Borrowers hereunder by considering the usage of one law firm to represent the
Banks and the Agent if appropriate under the circumstances.  The Borrowers agree
unconditionally to pay all stamp, document, transfer, recording or filing taxes
or fees and similar impositions now or hereafter determined by the Agent or any
Bank to be payable in connection with this Agreement or any other Loan Document,
and the Borrowers agree unconditionally to save the Agent and the Banks harmless
from and against any and all present or future claims, liabilities or losses
with respect to or resulting from any omission to pay or delay in paying any
such taxes, fees or impositions.

          10.4  Holidays.
                -------- 

          Whenever payment of a Loan to be made or taken hereunder shall be due
on a day which is not a Business Day such payment shall be due on the next
Business Day and such extension of time shall be included in computing interest
and fee, except that the Loans shall be due on the Business Day preceding the
Expiration Date if the Expiration Date is not a Business Day.  Whenever any
payment or action to be made or taken hereunder (other than payment of the

                                     -80-
<PAGE>
 
Loans) shall be stated to be due on a day which is not a Business Day, such
payment or action shall be made or taken on the next following Business Day
(except as provided in Section 3.2 with respect to Interest Periods under the
Euro-Rate Option), and such extension of time shall not be included in computing
interest or fees, if any, in connection with such payment or action.

          10.5  Funding by Branch, Subsidiary or Affiliate.
                ------------------------------------------ 

                10.5.1    Notional Funding.
                          ---------------- 

                Each Bank shall have the right from time to time, without notice
to the Borrowers, to deem any branch, Subsidiary or Affiliate (which for the
purposes of this Section 10.5 shall mean any corporation or association which is
directly or indirectly controlled by or is under direct or indirect common
control with any corporation or association which directly or indirectly
controls such Bank) of such Bank to have made, maintained or funded any Loan to
which the Euro-Rate Option applies at any time, provided that immediately
                                                --------                 
following (on the assumption that a payment were then due from the Borrowers to
such other office), and as a result of such change, the Borrowers would not be
under any greater financial obligation pursuant to Section 4.5 than it would
have been in the absence of such change.  Notional funding offices may be
selected by each Bank without regard to such Bank's actual methods of making,
maintaining or funding the Loans or any sources of funding actually used by or
available to such Bank.

                10.5.2    Actual Funding.
                          -------------- 

                Each Bank shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Bank to make or maintain such Loan subject to the last sentence of this Section
10.5.2. If any Bank causes a branch, Subsidiary or Affiliate to make or maintain
any part of the Loans hereunder, all terms and conditions of this Agreement
shall, except where the context clearly requires otherwise, be applicable to
such part of the Loans to the same extent as if such Loans were made or
maintained by such Bank, but in no event shall any Bank's use of such a branch,
Subsidiary or Affiliate to make or maintain any part of the Loans hereunder
cause such Bank or such branch, Subsidiary or Affiliate to incur any cost or
expenses payable by the Borrowers hereunder or require the Borrowers to pay any
other compensation to any Bank (including any expenses incurred or payable
pursuant to Section 4.5) which would otherwise not be incurred.

          10.6  Notices.
                ------- 

          All notices, requests, demands, directions and other communications

first-class postage prepaid, return receipt requested, and (e) if given by any
other means (including by air courier), when delivered; provided, that notices
                                                        --------  
to the Agent shall not be effective until received and provided, further, that
                                                       -------- 
any notices of a Potential Default or an Event of Default shall be sent by
facsimile or overnight delivery service. Any Bank giving any notice to any Loan
Party shall simultaneously send a copy thereof to the Agent, and the Agent shall
promptly notify the other Banks of the receipt by it of any such notice.

          10.7  Severability.
                ------------ 

          The provisions of this Agreement are intended to be severable.  If any
provision of this Agreement shall be held invalid or unenforceable in whole or
in part in any jurisdiction, such provision shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without in any
manner affecting the validity or enforceability thereof in any other
jurisdiction or the remaining provisions hereof in any jurisdiction.

          10.8  Governing Law.
                ------------- 

          Each Letter of Credit and Section 2.9 shall be subject to the Uniform
Customs and Practice for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500, as the same may be revised or amended
from time to time, and to the extent not inconsistent therewith, the internal
laws of the Commonwealth of Pennsylvania without regard to its conflict of laws
principles and the balance of this Agreement shall be deemed to be a contract
under the Laws of the Commonwealth of Pennsylvania and for all purposes shall be
governed by and construed and enforced in accordance with the internal laws of
the Commonwealth of Pennsylvania without regard to its conflict of laws
principles.

          10.9  Prior Understanding.
                ------------------- 

          This Agreement and the other Loan Documents supersede all prior
understandings and agreements, whether written or oral, between the parties

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

          All representations and warranties of the Loan Parties contained

and after the date hereof so long as the Borrowers may borrow or request Letters
of Credit hereunder and until termination of the Revolving Credit Commitments
and payment in full of the Loans and expiration or termination of all Letters of
Credit. All covenants and agreements of the Borrowers contained herein relating

          10.11 Successors and Assigns.
                ---------------------- 

                     (i)    This Agreement shall be binding upon and shall inure
to the benefit of the Banks, the Agent, the Loan Parties and their respective
successors and assigns, except that none of the Loan Parties may assign or
transfer any of its rights and Obligations hereunder or any interest herein.
Each Bank may, at its own cost, make assignments of or sell participations in
all or any part of its Revolving Credit Commitment and the Loans made by it to
one or more banks or other entities, subject to the consent of Option Care, Inc.
on behalf of the Borrowers and the Agent with respect to any assignee, such
consent not to be unreasonably withheld. In the case of an assignment, upon
receipt by the Agent of the Assignment and Assumption Agreement, the assignee
shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights, benefits and obligations as it would have if it had
been a signatory Bank hereunder, the Revolving Credit Commitments shall be
adjusted accordingly, and upon surrender of any Note subject to such assignment,
Option Care, Inc. on behalf of the Borrowers shall execute and deliver a new
Note to the assignee in an amount equal to the amount of the Revolving Credit
Commitment assumed by it and a new Revolving Credit Note to the assigning Bank
in an amount equal to the Revolving Credit Commitment retained by it hereunder.
Each assignment will be in the minimum principal amount of $5,000,000. The
assigning Bank shall pay to the Agent a service fee in the amount of $3,500 for
each assignment. In the case of a participation, the participant shall only have
the rights specified in Section 8.2.3 (the participant's rights against such
Bank in respect of such participation to be those set forth in the agreement
executed by such Bank in favor of the participant relating thereto and not to
include any voting rights except with respect to changes of the type referenced
in Sections 10.1.1, 10.1.2, or 10.1.3, all of such Bank's obligations under this
Agreement or any other Loan Document shall remain unchanged, and all amounts
payable by any Loan Party hereunder or thereunder shall be determined as if such
Bank had not sold such participation.

                     (ii)   Any assignee or participant which is not
incorporated under the Laws of the United States of America or a state thereof
shall deliver to Option Care, Inc. on behalf of the Borrowers and to the Agent
the form of certificate described in Section 10.17 relating to federal income
tax withholding. Each Bank may furnish any publicly available information
concerning any Loan Party or its Subsidiaries and any other information
concerning any Loan Party or its Subsidiaries in the possession of such Bank
from time to time to assignees

                                     -83-

and participants (including prospective assignees or participants), provided
                                                                    --------  
that such assignees and participants agree to be bound by the provisions of
Section 10.12.

                     (iii)  Notwithstanding any other provision in this
Agreement, any Bank may at any time pledge or grant a security interest in all
or any portion of its rights under this Agreement, its Note and the other Loan
Documents to any Federal Reserve Bank in accordance with Regulation A of the FRB
or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or consent
of the Borrowers or the Agent. No such pledge or grant of a security interest
shall release the transferor Bank of its obligations hereunder or under any
other Loan Document.

          10.12 Confidentiality.
                --------------- 

          The Agent and the Banks each agree to keep confidential all
information obtained from any Loan Party or its Subsidiaries which is nonpublic
and confidential or proprietary in nature (including any information the
Borrowers specifically designate as confidential), except as provided below, and
to use such information only in connection with their respective capacities
under this Agreement and for the purposes contemplated hereby.  The Agent and
the Banks shall be permitted to disclose such information (i) to outside legal
counsel, accountants and other professional advisors who need to know such
information in connection with the administration and enforcement of this
Agreement, subject to agreement of such Persons to maintain the confidentiality,
(ii) to assignees and participants as contemplated by Section 10.11 provided
                                                                    --------
that they shall execute an agreement in favor of the Loan Parties covering the
matters set forth in this Section 10.12, (iii) to the extent requested by any
bank regulatory authority or, with notice to the Borrower, as otherwise required
by applicable Law or by any subpoena or similar legal process, or in connection
with any investigation or proceeding arising out of the transactions
contemplated by this Agreement, (iv) if it becomes publicly available other than
as a result of a breach of this Agreement or becomes available from a source not
bound by confidentiality restrictions, or (v) if the Borrowers shall have
consented to such disclosure.

          10.13 Counterparts.
                ------------ 

          This Agreement may be executed by different parties hereto on any
number of separate counterparts, each of which, when so executed and delivered,
shall be an original, and all such counterparts shall together constitute one
and the same instrument.

          10.14 Agent's or Bank's Consent.
                ------------------------- 

          Except as otherwise provided in the Loan Documents, whenever the
Agent's or any Bank's consent is required to be obtained under this Agreement or
any of the other Loan Documents as a condition to any action, inaction,
condition or event, the Agent and each Bank shall be authorized to give or
withhold such consent in its reasonable discretion.

          10.17 Tax Withholding Clause.
                ---------------------- 

          Each Bank or assignee or participant of a Bank that is not
incorporated under the Laws of the United States of America or a state thereof
agrees that it will deliver to Option Care, Inc. on behalf of the Borrowers and
to the Agent two (2) duly completed copies of the following:  (i) Internal
Revenue Service Form W-9, 4224 or 1001, or other applicable form prescribed by
the Internal Revenue Service, certifying that such Bank, assignee or participant
is entitled to receive payments under this Agreement and the other Loan
Documents without deduction or withholding of any United States federal income
taxes, or is subject to such tax at a reduced rate under an applicable tax
treaty, or (ii) Internal Revenue Service Form W-8 or other applicable form or a
certificate of such Bank, assignee or participant indicating that no such
exemption or reduced rate is allowable with respect to such payments.  Each
Bank, assignee or participant required to deliver to Option Care, Inc. on behalf
of the Borrowers and to the Agent a form or certificate pursuant to the
preceding sentence shall deliver such form or certificate as follows: (A) each
Bank which is a party hereto on the Closing Date shall deliver such form or
certificate at least five (5) Business Days prior to the first date on which any
interest or fees are payable by the Borrowers hereunder for the account of such
Bank; (B) each assignee or participant shall deliver such form or 

                                     -85-

certificate at least five (5) Business Days before the effective date of such
assignment or participation (unless the Agent in its sole discretion shall
permit such assignee or participant to deliver such form or certificate less
than five (5) Business Days before such date in which case it shall be due on
the date specified by the Agent). Each Bank, assignee or participant which so
delivers a Form W-8, W-9, 4224 or 1001 further undertakes to deliver to Option
Care, Inc. on behalf of Borrowers and to the Agent two (2) additional copies of
such form (or a successor form) on or before the date that such form expires or
becomes obsolete or after the occurrence of any event requiring a change in the
most recent form so delivered by it, and such amendments thereto or extensions
or renewals thereof as may be reasonably requested by the Borrowers or the
Agent, either certifying that such Bank, assignee or participant is entitled to
receive payments under this Agreement and the other Loan Documents without
deduction or withholding of any United States federal income taxes or is subject
to such tax at a reduced rate under an applicable tax treaty or stating that no
such exemption or reduced rate is allowable. The Agent shall be entitled to
withhold United States federal income taxes at the full withholding rate unless
the Bank, assignee or participant establishes an exemption or that it is subject
to a reduced rate as established pursuant to the above provisions.

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by OPTION CARE, INC., a
Delaware corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL ASSOCIATION,
as agent for the Banks (the "AGENT"), with an address at One PNC Plaza, 249 5th
Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
described in the previous sentence, whether in whole or in part, and shall
include, but not be
<PAGE>
 
limited to, (i) all principal amounts due,  together with any interest accruing
thereon and any and all fees and expenses (including attorneys' fees and
expenses) incurred in connection therewith, and (ii) all amounts that would be
due if effect were not given to the bankruptcy, insolvency or other similar laws
of general application relating to the enforcement of creditors' rights or to
general principles of equity; plus all interest, costs and expenses (including
attorneys' fees) which may accrue or be incurred on account of any liability of
any of the Borrowers to Agent, or in attempting to collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not

                                      -2-
<PAGE>
 
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.  The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to

                                      -3-
<PAGE>
 
     the Agent from time to time is, or will be at the time such information is
     furnished, true, correct and complete in all material respects; the
     Guarantor has good and marketable title to all properties, assets and other
     rights which the Guarantor purports to own or which are reflected as owned
     in the Guarantor's books and records, free and clear of all liens except as
     previously disclosed in writing to the Agent pursuant to the Credit
     Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial

                                      -4-
<PAGE>
 
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any default.  No course of dealing between any of
the Borrowers, the Guarantor, the Agent or the Banks or any of the Banks' agents
or employees shall be effective to change, modify or discharge any provision of
this Guaranty or to constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any other person under any law, including without
limitation any bankruptcy law, state or federal law, common law or equity, all
as though such payment, enforcement or allocation had not

                                      -5-
<PAGE>
 
been made, and all as determined by the Agent and the Banks.  Nothing set forth
in this paragraph is intended to expand on or increase the definition of
Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor waives any
objection to jurisdiction and venue of any action instituted against him as
provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.

     in the financial statements and other documents and reports furnished by
     the Guarantor to

                                      -3-
<PAGE>
 
     the Agent from time to time is, or will be at the time such information is
     furnished, true, correct and complete in all material respects; the
     Guarantor has good and marketable title to all properties, assets and other
     rights which the Guarantor purports to own or which are reflected as owned
     in the Guarantor's books and records, free and clear of all liens except as
     previously disclosed in writing to the Agent pursuant to the Credit
     Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial

                                      -4-
<PAGE>
 
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any default.  No course of dealing between any of
the Borrowers, the Guarantor, the Agent or the Banks or any of the Banks' agents
or employees shall be effective to change, modify or discharge any provision of
this Guaranty or to constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any other person under any law, including without
limitation any bankruptcy law, state or federal law, common law or equity, all
as though such payment, enforcement or allocation had not

                                      -5-
<PAGE>
 
been made, and all as determined by the Agent and the Banks.  Nothing set forth
in this paragraph is intended to expand on or increase the definition of
Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor waives any
objection to jurisdiction and venue of any action instituted against him as
provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by OPTION CARE ENTERPRISES, a
California corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL ASSOCIATION,
as agent for the Banks (the "AGENT"), with an address at One PNC Plaza, 249 5th
Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
described in the previous sentence, whether in whole or in part, and shall
include, but not be
<PAGE>
 
limited to, (i) all principal amounts due,  together with any interest accruing
thereon and any and all fees and expenses (including attorneys' fees and
expenses) incurred in connection therewith, and (ii) all amounts that would be
due if effect were not given to the bankruptcy, insolvency or other similar laws
of general application relating to the enforcement of creditors' rights or to
general principles of equity; plus all interest, costs and expenses (including
attorneys' fees) which may accrue or be incurred on account of any liability of
any of the Borrowers to Agent, or in attempting to collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not

                                      -2-
<PAGE>
 
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.  The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to

                                      -3-
<PAGE>
 
     the Agent from time to time is, or will be at the time such information is
     furnished, true, correct and complete in all material respects; the
     Guarantor has good and marketable title to all properties, assets and other
     rights which the Guarantor purports to own or which are reflected as owned
     in the Guarantor's books and records, free and clear of all liens except as
     previously disclosed in writing to the Agent pursuant to the Credit
     Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial

                                      -4-

exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any default.  No course of dealing between any of
the Borrowers, the Guarantor, the Agent or the Banks or any of the Banks' agents
or employees shall be effective to change, modify or discharge any provision of
this Guaranty or to constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and

Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any other person under any law, including without
limitation any bankruptcy law, state or federal law, common law or equity, all
as though such payment, enforcement or allocation had not

                                      -5-

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by PHARMACARE OF SOUTHWEST

One PNC Plaza, 249 5th Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
<PAGE>
 
described in the previous sentence, whether in whole or in part, and shall
include, but not be limited to, (i) all principal amounts due,  together with
any interest accruing thereon and any and all fees and expenses (including
attorneys' fees and expenses) incurred in connection therewith, and (ii) all
amounts that would be due if effect were not given to the bankruptcy, insolvency
or other similar laws of general application relating to the enforcement of
creditors' rights or to general principles of equity; plus all interest, costs
and expenses (including attorneys' fees) which may accrue or be incurred on
account of any liability of any of the Borrowers to Agent, or in attempting to
collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to

anyone; (c) defenses to pay or perform based upon any of the Guaranteed
Indebtedness not being a valid and binding obligation of the Borrowers
enforceable in accordance with its terms for any reason whatsoever; (d) all
other notices to which the Guarantor may be entitled but which may legally be
waived; (e) any disability of the Borrowers (other than payment in full)
including absence or cessation of liability for any reason whatsoever; (f) any
defense or circumstance which might otherwise constitute a legal or equitable
discharge of a guarantor or surety; and (g) all rights under any state or
federal statute dealing with or affecting the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

                                      -3-
<PAGE>
 
          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g) Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in

                                      -4-
<PAGE>
 
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any

                                      -5-
<PAGE>
 
other person under any law, including without limitation any bankruptcy law,
state or federal law, common law or equity, all as though such payment,
enforcement or allocation had not been made, and all as determined by the Agent
and the Banks.  Nothing set forth in this paragraph is intended to expand on or
increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor waives any
objection to jurisdiction and venue of any action instituted against him as
provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.

     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in

                                      -4-
<PAGE>
 
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any

                                      -5-
<PAGE>
 
other person under any law, including without limitation any bankruptcy law,
state or federal law, common law or equity, all as though such payment,
enforcement or allocation had not been made, and all as determined by the Agent
and the Banks.  Nothing set forth in this paragraph is intended to expand on or
increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses

be deemed to be completed upon actual receipt thereof.  The Guarantor waives any
objection to jurisdiction and venue of any action instituted against him as
provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by HOME CARE OF COLUMBIA,
INC., a Missouri corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL
ASSOCIATION, as agent for the Banks (the "AGENT"), with an address at One PNC
Plaza, 249 5th Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be
<PAGE>
 
amended, modified, extended, restated, replaced, renewed, refunded or
supplemented.  "GUARANTEED INDEBTEDNESS" shall mean any and all indebtedness,
obligations or liabilities described in the previous sentence, whether in whole
or in part, and shall include, but not be limited to, (i) all principal amounts
due,  together with any interest accruing thereon and any and all fees and
expenses (including attorneys' fees and expenses) incurred in connection
therewith, and (ii) all amounts that would be due if effect were not given to
the bankruptcy, insolvency or other similar laws of general application relating
to the enforcement of creditors' rights or to general principles of equity; plus
all interest, costs and expenses (including attorneys' fees) which may accrue or
be incurred on account of any liability of any of the Borrowers to Agent, or in
attempting to collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect

                                      -2-
<PAGE>
 
to any of the Guaranteed Indebtedness; (b) presentment for payment, notice of
non-payment or non-performance, demand, protest, notice of protest and notice of
dishonor or default to anyone; (c) defenses to pay or perform based upon any of
the Guaranteed Indebtedness not being a valid and binding obligation of the
Borrowers enforceable in accordance with its terms for any reason whatsoever;
(d) all other notices to which the Guarantor may be entitled but which may
legally be waived; (e) any disability of the Borrowers (other than payment in
full) including absence or cessation of liability for any reason whatsoever; (f)
any defense or circumstance which might otherwise constitute a legal or
equitable discharge of a guarantor or surety; and (g) all rights under any state
or federal statute dealing with or affecting the rights of creditors.

          9.  The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

                                      -3-
<PAGE>
 
          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in

                                      -4-
<PAGE>
 
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be

any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be
<PAGE>
 
amended, modified, extended, restated, replaced, renewed, refunded or
supplemented. "GUARANTEED INDEBTEDNESS" shall mean any and all indebtedness,
obligations or liabilities described in the previous sentence, whether in whole
or in part, and shall include, but not be limited to, (i) all principal amounts
due, together with any interest accruing thereon and any and all fees and
expenses (including attorneys' fees and expenses) incurred in connection
therewith, and (ii) all amounts that would be due if effect were not given to
the bankruptcy, insolvency or other similar laws of general application relating
to the enforcement of creditors' rights or to general principles of equity; plus
all interest, costs and expenses (including attorneys' fees) which may accrue or
be incurred on account of any liability of any of the Borrowers to Agent, or in
attempting to collect the same.

          3.   The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.   The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.   The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.   The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.   The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.   The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect

                                      -2-
<PAGE>
 
to any of the Guaranteed Indebtedness; (b) presentment for payment, notice of
non-payment or non-performance, demand, protest, notice of protest and notice of
dishonor or default to anyone; (c) defenses to pay or perform based upon any of
the Guaranteed Indebtedness not being a valid and binding obligation of the
Borrowers enforceable in accordance with its terms for any reason whatsoever;
(d) all other notices to which the Guarantor may be entitled but which may
legally be waived; (e) any disability of the Borrowers (other than payment in
full) including absence or cessation of liability for any reason whatsoever; (f)
any defense or circumstance which might otherwise constitute a legal or
equitable discharge of a guarantor or surety; and (g) all rights under any state
or federal statute dealing with or affecting the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

                                      -3-
<PAGE>
 
          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty. Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable. Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived. Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in

                                      -4-
<PAGE>
 
equity or by suit or otherwise. No delay on the part of the Agent or any Bank in
exercising any right, power or privilege shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default. No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement. Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty. Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness. Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent. The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any

                                      -5-
<PAGE>
 
other person under any law, including without limitation any bankruptcy law,
state or federal law, common law or equity, all as though such payment,
enforcement or allocation had not been made, and all as determined by the Agent
and the Banks. Nothing set forth in this paragraph is intended to expand on or
increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.


          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor waives any
objection to jurisdiction and venue of any action instituted against him as
provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,

to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at

Borrowers arising under or in connection with the Loan Documents, as the same
may be amended, modified, extended, restated, replaced, renewed, refunded or
supplemented.  "GUARANTEED INDEBTEDNESS" shall mean any and all indebtedness,
obligations or liabilities described in the previous sentence, whether in whole
or in part, and shall include, but not be limited to, (i) all principal amounts
due,  together with any interest accruing thereon and any and all fees and
expenses (including attorneys' fees and expenses) incurred in connection
therewith, and (ii) all amounts that would be due if effect were not given to
the bankruptcy, insolvency or other similar laws of general application relating
to the enforcement of creditors' rights or to general principles of equity; plus
all interest, costs and expenses (including attorneys' fees) which may accrue or
be incurred on account of any liability of any of the Borrowers to Agent, or in
attempting to collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or

notice of non-payment or non-performance, demand, protest, notice of protest and
notice of dishonor or default to anyone; (c) defenses to pay or perform based
upon any of the Guaranteed Indebtedness not being a valid and binding obligation
of the Borrowers enforceable in accordance with its terms for any reason
whatsoever; (d) all other notices to which the Guarantor may be entitled but
which may legally be waived; (e) any disability of the Borrowers (other than
payment in full) including absence or cessation of liability for any reason

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,

     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

                                      -3-
<PAGE>
 
          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost

under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan

notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is

                                      -4-

right or remedy shall not preclude the exercise of any other rights or remedies,
all of which shall be cumulative and shall be in addition to any other right or
remedy given hereunder or under any other agreement between the parties or which
may now or hereafter exist at law or in equity or by suit or otherwise.  No
delay on the part of the Agent or any Bank in exercising any right, power or
privilege shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any default.  No course of dealing between any of
the Borrowers, the Guarantor, the Agent or the Banks or any of the Banks' agents
or employees shall be effective to change, modify or discharge any provision of
this Guaranty or to constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor

                                      -5-

allocation by the Agent and the Banks of payments received is subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or is required to be repaid or otherwise restored to the
Borrowers, the Guarantor, a trustee, an estate receiver or any other person
under any law, including without limitation any bankruptcy law, state or federal
law, common law or equity, all as though such payment, enforcement or allocation
had not been made, and all as determined by the Agent and the Banks.  Nothing
set forth in this paragraph is intended to expand on or increase the definition
of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.
                                                                         _______

Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by WHATCOM PHARMACEUTICAL
SERVICES, INC., a Washington corporation ("GUARANTOR") in favor of PNC BANK,
NATIONAL ASSOCIATION, as agent for the Banks (the "AGENT"), with an address at
One PNC Plaza, 249 5th Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or
<PAGE>
 
otherwise, of any and all existing and future indebtedness, obligations or
liabilities of the Borrowers arising under or in connection with the Loan
Documents, as the same may be amended, modified, extended, restated, replaced,
renewed, refunded or supplemented. "GUARANTEED INDEBTEDNESS" shall mean any and
all indebtedness, obligations or liabilities described in the previous sentence,
whether in whole or in part, and shall include, but not be limited to, (i) all
principal amounts due, together with any interest accruing thereon and any and
all fees and expenses (including attorneys' fees and expenses) incurred in
connection therewith, and (ii) all amounts that would be due if effect were not
given to the bankruptcy, insolvency or other similar laws of general application
relating to the enforcement of creditors' rights or to general principles of
equity; plus all interest, costs and expenses (including attorneys' fees) which
may accrue or be incurred on account of any liability of any of the Borrowers to
Agent, or in attempting to collect the same.

          3.   The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.   The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5. The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.   The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.   The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

                                      -2-
<PAGE>
 
          8.   The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law: (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.


                                      -3-
<PAGE>
 
          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12. The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable. Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived. Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is

                                      -4-
<PAGE>
 
not intended to be exhaustive and the exercise by the Agent and the Banks of any
right or remedy shall not preclude the exercise of any other rights or remedies,
all of which shall be cumulative and shall be in addition to any other right or
remedy given hereunder or under any other agreement between the parties or which
may now or hereafter exist at law or in equity or by suit or otherwise. No delay
on the part of the Agent or any Bank in exercising any right, power or privilege
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right, power or privilege preclude other or further exercise thereof or
the exercise of any other right, power or privilege or shall be construed to be
a waiver of any default. No course of dealing between any of the Borrowers, the
Guarantor, the Agent or the Banks or any of the Banks' agents or employees shall
be effective to change, modify or discharge any provision of this Guaranty or to
constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty. Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness. Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent. The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor

                                      -5-

or the proceeds of any enforcement of any security interest of Agent or any
allocation by the Agent and the Banks of payments received is subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or is required to be repaid or otherwise restored to the
Borrowers, the Guarantor, a trustee, an estate receiver or any other person
under any law, including without limitation any bankruptcy law, state or federal
law, common law or equity, all as though such payment, enforcement or allocation
had not been made, and all as determined by the Agent and the Banks. Nothing set
forth in this paragraph is intended to expand on or increase the definition of
Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the

agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER

equity; plus all interest, costs and expenses (including attorneys' fees) which
may accrue or be incurred on account of any liability of any of the Borrowers to
Agent, or in attempting to collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to

Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.  The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent

     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

                                      -3-
<PAGE>
 
          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is

                                      -4-
<PAGE>
 
not intended to be exhaustive and the exercise by the Agent and the Banks of any
right or remedy shall not preclude the exercise of any other rights or remedies,
all of which shall be cumulative and shall be in addition to any other right or
remedy given hereunder or under any other agreement between the parties or which
may now or hereafter exist at law or in equity or by suit or otherwise.  No
delay on the part of the Agent or any Bank in exercising any right, power or
privilege shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any default.  No course of dealing between any of
the Borrowers, the Guarantor, the Agent or the Banks or any of the Banks' agents
or employees shall be effective to change, modify or discharge any provision of
this Guaranty or to constitute a waiver of any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor

                                      -5-
<PAGE>
 
or the proceeds of any enforcement of any security interest of Agent or any
allocation by the Agent and the Banks of payments received is subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or is required to be repaid or otherwise restored to the
Borrowers, the Guarantor, a trustee, an estate receiver or any other person
under any law, including without limitation any bankruptcy law, state or federal
law, common law or equity, all as though such payment, enforcement or allocation
had not been made, and all as determined by the Agent and the Banks.  Nothing
set forth in this paragraph is intended to expand on or increase the definition
of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to the Guarantor at the addresses
provided for in Section 10.6 of the Credit Agreement and service so made shall
be deemed to be completed upon actual receipt thereof.  The Guarantor

                                      -6-

waives any objection to jurisdiction and venue of any action instituted against
him as provided herein and agrees not to assert any defense based on lack of
jurisdiction or venue.


          Witness the due execution hereof, as of the day first written above.

defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

any of the Borrowers to Agent, or in attempting to collect the same.

and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are

occurrence, including, but not limited to (a) any failure or delay to exercise

payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies

     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset

     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the

any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any

Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor

                                      -5-

from, disgorged by or is required to be repaid or otherwise restored to the
Borrowers, the Guarantor, a trustee, an estate receiver or any other person
under any law, including without limitation any bankruptcy law, state or federal

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by OPTION CARE HOSPICE, INC.,
a Missouri corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL ASSOCIATION,
as agent for the Banks (the "AGENT"), with an address at One PNC Plaza, 249 5th
Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.  Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.
<PAGE>
 
          2.  The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
described in the previous sentence, whether in whole or in part, and shall
include, but not be limited to, (i) all principal amounts due,  together with
any interest accruing thereon and any and all fees and expenses (including
attorneys' fees and expenses) incurred in connection therewith, and (ii) all
amounts that would be due if effect were not given to the bankruptcy, insolvency
or other similar laws of general application relating to the enforcement of
creditors' rights or to general principles of equity; plus all interest, costs
and expenses (including attorneys' fees) which may accrue or be incurred on
account of any liability of any of the Borrowers to Agent, or in attempting to
collect the same.

          3.  The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.  The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.  The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.  The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.  The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection

                                      -2-
<PAGE>
 
with the enforcement of the Banks' rights hereunder or which would otherwise not
have been incurred but for the Guaranteed Indebtedness.

          8.  The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity

                                      -3-
<PAGE>
 
     is or was necessary to the valid execution and delivery of this Guaranty or
     the Guarantor's performance of its agreements and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

                                      -4-
<PAGE>
 
          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated;

                                      -5-
<PAGE>
 
provided, however, that this Guaranty shall be reinstated (as the case may be)
if at any time any payment of any of the Guaranteed Indebtedness made by the
Borrowers or the Guarantor or the proceeds of any enforcement of any security
interest of Agent or any allocation by the Agent and the Banks of payments
received is subsequently invalidated, declared to be fraudulent or preferential,
set aside, recovered from, disgorged by or is required to be repaid or otherwise
restored to the Borrowers, the Guarantor, a trustee, an estate receiver or any
other person under any law, including without limitation any bankruptcy law,
state or federal law, common law or equity, all as though such payment,
enforcement or allocation had not been made, and all as determined by the Agent
and the Banks.  Nothing set forth in this paragraph is intended to expand on or
increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to

with or without joining or proceeding against the Borrowers.

          7.   The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection

                                      -2-

with the enforcement of the Banks' rights hereunder or which would otherwise not
have been incurred but for the Guaranteed Indebtedness.

          8.   The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity

                                      -3-
<PAGE>
 
     is or was necessary to the valid execution and delivery of this Guaranty or
     the Guarantor's performance of its agreements and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

                                      -4-
<PAGE>
 
          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated;

                                      -5-
<PAGE>
 
provided, however, that this Guaranty shall be reinstated (as the case may be)
if at any time any payment of any of the Guaranteed Indebtedness made by the
Borrowers or the Guarantor or the proceeds of any enforcement of any security
interest of Agent or any allocation by the Agent and the Banks of payments
received is subsequently invalidated, declared to be fraudulent or preferential,
set aside, recovered from, disgorged by or is required to be repaid or otherwise
restored to the Borrowers, the Guarantor, a trustee, an estate receiver or any
other person under any law, including without limitation any bankruptcy law,
state or federal law, common law or equity, all as though such payment,
enforcement or allocation had not been made, and all as determined by the Agent
and the Banks.  Nothing set forth in this paragraph is intended to expand on or
increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.

          25.  The Guarantor hereby irrevocably consents to the jurisdiction of
the Court of Common Pleas of Allegheny County and the United States District
Court for the Western District of Pennsylvania, and waives personal service of
any and all process upon him and consents that all such services of process be
made by certified or registered mail directed to

                                      -6-
<PAGE>
 
the Guarantor at the addresses provided for in Section 10.6 of the Credit
Agreement and service so made shall be deemed to be completed upon actual
receipt thereof.  The Guarantor waives any objection to jurisdiction and venue
of any action instituted against him as provided herein and agrees not to assert
any defense based on lack of jurisdiction or venue.


          Witness the due execution hereof, as of the day first written above.

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by MANAGEMENT BY INFORMATION,
INC., a Delaware corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL
ASSOCIATION, as agent for the Banks (the "AGENT"), with an address at One PNC
Plaza, 249 5th Avenue, Pittsburgh, Pennsylvania 15222-2709.

                               WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:

          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.
<PAGE>
 
          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
described in the previous sentence, whether in whole or in part, and shall
include, but not be limited to, (i) all principal amounts due,  together with
any interest accruing thereon and any and all fees and expenses (including
attorneys' fees and expenses) incurred in connection therewith, and (ii) all
amounts that would be due if effect were not given to the bankruptcy, insolvency
or other similar laws of general application relating to the enforcement of
creditors' rights or to general principles of equity; plus all interest, costs
and expenses (including attorneys' fees) which may accrue or be incurred on
account of any liability of any of the Borrowers to Agent, or in attempting to
collect the same.

          3.   The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.   The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.   The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.   The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

          7.   The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection

                                      -2-
<PAGE>
 
with the enforcement of the Banks' rights hereunder or which would otherwise not
have been incurred but for the Guaranteed Indebtedness.

          8.   The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity

<PAGE>
 
     is or was necessary to the valid execution and delivery of this Guaranty or
     the Guarantor's performance of its agreements and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time

     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost

the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly waived.  Upon any such
default, the Banks shall have and may exercise all the rights and remedies as
may be provided hereunder, by law or otherwise.

                                      -4-

Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to

any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

Borrowers have terminated;

                                      -5-

                       GUARANTY AND SURETYSHIP AGREEMENT

          THIS GUARANTY AND SURETYSHIP AGREEMENT ("GUARANTY") is made and
entered into as of the 23rd day of December, 1996, by OPTION CARE OF OKLAHOMA,
INC., a Delaware corporation ("GUARANTOR") in favor of PNC BANK, NATIONAL
ASSOCIATION, as agent for the Banks (the "AGENT"), with an address at One PNC
Plaza, 249 5th Avenue, Pittsburgh, Pennsylvania 15222-2709.

                                WITNESSETH THAT:

          WHEREAS, the Guarantor and certain of its affiliates, as Borrowers,
the Agent and the other Banks party thereto have entered into that certain
Credit Agreement dated of even date herewith (the "Credit Agreement"), pursuant
to which the Banks agreed to make certain Loans to the Borrowers for the purpose
of, among other things, funding the working capital requirements of the
Borrowers;

          WHEREAS, it is a condition to the Loans that each of the co-Borrowers
guaranty all obligations arising under the Loan Documents (as that term is
defined in the Credit Agreement); and

          WHEREAS, the Guarantor will benefit directly by the execution of the
Credit Agreement;

          NOW THEREFORE, in order to induce the Banks to enter into the Credit
Agreement, and intending to be legally bound hereby, the Guarantor hereby agrees
as follows:
<PAGE>
 
          1.   Defined terms used in this Guaranty shall have the same meaning
ascribed thereto in the Credit Agreement unless the context clearly indicates
otherwise.

          2.   The Guarantor hereby guaranties, absolutely and unconditionally,
and does hereby become surety for, the due performance including, but not
limited to, the full, prompt and punctual payment, as and when due, whether at
maturity, by acceleration or otherwise, of any and all existing and future
indebtedness, obligations or liabilities of the Borrowers arising under or in
connection with the Loan Documents, as the same may be amended, modified,
extended, restated, replaced, renewed, refunded or supplemented.  "GUARANTEED
INDEBTEDNESS" shall mean any and all indebtedness, obligations or liabilities
described in the previous sentence, whether in whole or in part, and shall
include, but not be limited to, (i) all principal amounts due,  together with
any interest accruing thereon and any and all fees and expenses (including
attorneys' fees and expenses) incurred in connection therewith, and (ii) all
amounts that would be due if effect were not given to the bankruptcy, insolvency
or other similar laws of general application relating to the enforcement of
creditors' rights or to general principles of equity; plus all interest, costs
and expenses (including attorneys' fees) which may accrue or be incurred on
account of any liability of any of the Borrowers to Agent, or in attempting to
collect the same.

          3.   The Guarantor hereby agrees and acknowledges that its obligations
and liabilities to the Agent hereunder are part of the Guaranteed Indebtedness
and that its obligations and liabilities are secured by the Loan Documents to
which the Guarantor is a party.

          4.   The Guarantor hereby agrees that this Guaranty is continuing in
nature and shall survive and continue in full force notwithstanding the
dissolution or liquidation of, or the insolvency or bankruptcy of, merger or any
other corporate change or other occurrence whatsoever affecting the obligations
and liabilities of the Borrowers, regardless of when any indebtedness to the
Banks may accrue or be deemed to accrue.

          5.   The Guarantor agrees that its obligations under this Guaranty are
absolute and unconditional and shall not be affected in any way by any event or
occurrence, including, but not limited to (a) any failure or delay to exercise
any right, power or privilege hereunder; (b) any single or partial exercise of
any right, power or privilege hereunder; and (c) any failure to insist upon
strict performance hereunder.

          6.   The Guarantor agrees that this is a guaranty of performance and
payment and not merely of collection; that in the event of any default or the
occurrence or existence of a default under the Loan Documents or failure of the
Borrowers to perform any of their respective obligations, whether of payment or
otherwise, under or with respect to any of the Guaranteed Indebtedness, the
Guarantor will perform said obligations without offset of any kind and without
any requirement that any rights or remedies which may have been pursued against
the Borrowers and regardless of the existence or adequacy of rights or remedies
against the Borrowers; and that in any right of action accruing to the Agent or
the Banks, the Agent or the Banks may elect to proceed against the Guarantor,
with or without joining or proceeding against the Borrowers.

                                      -2-
<PAGE>
 
          7.   The Guarantor hereby agrees to reimburse the Agent and the Banks
for all costs and expenses, including reasonable attorneys' fees and expenses
incurred in connection with the enforcement of the Banks' rights hereunder or
which would otherwise not have been incurred but for the Guaranteed
Indebtedness.

          8.   The Guarantor hereby unconditionally and irrevocably waives, to
the extent permitted by applicable law:  (a) notice of acceptance of this
Guaranty and any notice regarding the performance or non-performance of the
Borrowers or any of them with respect to any of the Guaranteed Indebtedness; (b)
presentment for payment, notice of non-payment or non-performance, demand,
protest, notice of protest and notice of dishonor or default to anyone; (c)
defenses to pay or perform based upon any of the Guaranteed Indebtedness not
being a valid and binding obligation of the Borrowers enforceable in accordance
with its terms for any reason whatsoever; (d) all other notices to which the
Guarantor may be entitled but which may legally be waived; (e) any disability of
the Borrowers (other than payment in full) including absence or cessation of
liability for any reason whatsoever; (f) any defense or circumstance which might
otherwise constitute a legal or equitable discharge of a guarantor or surety;
and (g) all rights under any state or federal statute dealing with or affecting
the rights of creditors.

          9.   The Guarantor hereby agrees that the Agent or the Banks without
notice to the Guarantor, may deal with the Guaranteed Indebtedness and any
collateral security therefor in such manner the Agent or the Banks may deem
advisable and may renew, extend or increase the Guaranteed Indebtedness or any
part thereof; accept partial payment, or settle, release, compound, or
compromise the same; demand additional collateral security therefor, and
substitute or release the same; and may compromise or settle with or release and
discharge from liability any other guarantor or any other person totally or
partially liable to the Agent or the Banks for the obligations, debts and
liabilities of the Borrowers to the Agent and the Banks, all without impairing
the liability of the Guarantor hereunder.

          10.  Until the Guaranteed Indebtedness is indefeasibly paid in full,
the Guaranteed Indebtedness will be subordinated pursuant to the Intercompany
Subordination Agreement.

          11.  The Guarantor hereby represents, warrants and covenants to Agent
as follows:

          (a)  The Guarantor has all necessary power and authority to execute,
     deliver and perform in accordance with this Guaranty; the Guarantor has all
     requisite power and authority to own and operate its properties and to
     carry on its business as now conducted and as proposed to be conducted.

          (b)  The execution, delivery and performance of this Guaranty are not
     in contravention of any law, order, judgment, decree or any indenture or
     agreement to which the Guarantor is a party or by which Guarantor or the
     Guarantor's property is bound; the Guaranty has been duly executed and
     constitutes the legal, valid and binding obligation of the Guarantor,
     enforceable in accordance with its terms.

                                      -3-
<PAGE>
 
          (c)  No authorization, consent, approval, license or exemption of, and
     no registration, qualification, designation, declaration or filing with,
     any person or entity is or was necessary to the valid execution and
     delivery of this Guaranty or the Guarantor's performance of its agreements
     and obligations hereunder.

          (d)  The Guarantor will promptly furnish to the Agent such information
     and documents relating to the Guarantor's financial condition, assets or
     liabilities, at such times and in such form and detail as Agent may
     reasonably request.

          (e)  To the best knowledge of the Guarantor, all information set forth
     in the financial statements and other documents and reports furnished by
     the Guarantor to the Agent from time to time is, or will be at the time
     such information is furnished, true, correct and complete in all material
     respects; the Guarantor has good and marketable title to all properties,
     assets and other rights which the Guarantor purports to own or which are
     reflected as owned in the Guarantor's books and records, free and clear of
     all liens except as previously disclosed in writing to the Agent pursuant
     to the Credit Agreement, and except for Permitted Liens.

          (f)  The Guarantor will promptly notify Agent of any default under
     this Guaranty or under the Loan Documents to which the Guarantor is a
     party.

          (g)  Except as disclosed in Schedule 5.1.7 to the Credit Agreement,
     there are no actions, suits, proceedings, or investigations pending or
     threatened against or affecting the Guarantor, or the business or any asset
     owned by the Guarantor, before any court or governmental department, agency
     or instrumentality which are reasonably likely to have a material adverse
     effect on the financial condition of the Guarantor.

          (h)  Except for guaranties of the obligations of the Borrowers, and
     except as disclosed in the Credit Agreement, the Guarantor is not liable in
     respect of any guaranties except this Guaranty.  Except as permitted by the
     Credit Agreement, the Guarantor agrees not to become liable in respect to
     any other agreements guarantying obligations or indebtedness without the
     prior written consent of the Agent.

          (i)  The Guarantor shall take all necessary action, at its own cost
     and expense, to observe and perform its agreements and covenants, and keep
     the representations and warranties true, correct and complete under this
     Guaranty.

          (j)  The Guarantor's agreements, covenants, representations and
     warranties under this Guaranty are continuing ones, shall at all times
     remain true, correct and complete and shall at all times be observed and
     performed.

          12.  The Guarantor hereby agrees that if there is an Event of Default
under the Credit Agreement, then the Guarantor shall be in default hereunder and
the Banks shall have the right to declare all or any part of the Guaranteed
Indebtedness to be due and payable.  Except as expressly provided in the Loan
Documents, such declaration may be made without presentment, demand, protest or
notice of any kind, all of which are hereby expressly

                                      -4-
<PAGE>
 
waived.  Upon any such default, the Banks shall have and may exercise all the
rights and remedies as may be provided hereunder, by law or otherwise.

          13.  The enumeration of the Agent's and the Banks' rights and remedies
set forth in this Guaranty and in the other Loan Documents to which the
Guarantor is a party is not intended to be exhaustive and the exercise by the
Agent and the Banks of any right or remedy shall not preclude the exercise of
any other rights or remedies, all of which shall be cumulative and shall be in
addition to any other right or remedy given hereunder or under any other
agreement between the parties or which may now or hereafter exist at law or in
equity or by suit or otherwise.  No delay on the part of the Agent or any Bank
in exercising any right, power or privilege shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any default.  No
course of dealing between any of the Borrowers, the Guarantor, the Agent or the
Banks or any of the Banks' agents or employees shall be effective to change,
modify or discharge any provision of this Guaranty or to constitute a waiver of
any default.

          14.  All notices, and other communications given or made pursuant to
this Agreement shall be in writing and shall be deemed to have been duly given
or made in accordance with Section 10.6 of the Credit Agreement.  Any party
hereto may change the address to which notice to it, or copies thereof, shall be
addressed, by giving notice thereof to the other parties hereto in conformity
with the foregoing.

          15.  Any deposits or other sums at any time credited by or due from
any office of the Agent or the Banks to the Guarantor (regardless of the
currency thereof and whether general or special, contingent or unmatured), and
any securities or other property of the Guarantor at any time in the possession
of any office of the Agent or the Banks, may at all times be treated as
collateral for the payment of this Guaranty.  Regardless of the adequacy of
collateral, the Agent and the Banks may apply or set-off such deposits or other
sums against such liabilities, without notice or demand, at any time after any
default by the Borrowers in payment of the Guaranteed Indebtedness.  Every right
of set-off and lien shall continue in full force and effect until full, final
and complete satisfaction of the Indebtedness.

          16.  This Guaranty is fully assignable and transferable by the Agent
to any permitted assignee under the Credit Agreement; however, the duties and
obligations of the Guarantor may not be delegated or transferred by the
Guarantor without the prior written consent of the Agent.  The rights and
privileges of Agent hereunder shall inure to the benefit of the its successors
and assigns and the duties and obligations of the Guarantor shall bind the
Guarantor's legal representatives, heirs and permitted assigns.

          17.  This Guaranty shall in all respects be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without regard
to its conflict of law doctrines.

          18.  The obligations of the Guarantor hereunder are joint and several
with the obligations of any other guarantor of all or any portion of the
Guaranteed Indebtedness.

                                      -5-
<PAGE>
 
          19.  This Guaranty shall terminate only when the Guaranteed
Indebtedness is paid in full and the obligations of the Banks to lend to the
Borrowers have terminated; provided, however, that this Guaranty shall be
reinstated (as the case may be) if at any time any payment of any of the
Guaranteed Indebtedness made by the Borrowers or the Guarantor or the proceeds
of any enforcement of any security interest of Agent or any allocation by the
Agent and the Banks of payments received is subsequently invalidated, declared
to be fraudulent or preferential, set aside, recovered from, disgorged by or is
required to be repaid or otherwise restored to the Borrowers, the Guarantor, a
trustee, an estate receiver or any other person under any law, including without
limitation any bankruptcy law, state or federal law, common law or equity, all
as though such payment, enforcement or allocation had not been made, and all as
determined by the Agent and the Banks.  Nothing set forth in this paragraph is
intended to expand on or increase the definition of Guaranteed Indebtedness.

          20.  If any provision of this Guaranty is held invalid or
unenforceable to any extent or in any application, the remainder of this
Guaranty, shall not be affected thereby.

          21.  Unless the context of this Guaranty otherwise clearly requires,
references to the plural include the singular, the singular the plural and the
part the whole and "or" has the inclusive meaning represented by the phrase
"and/or".

          22.  The Agent and the Guarantor may from time to time enter into
agreements amending, supplementing or modifying this Guaranty; provided,
however, that any such amendment, supplement or modification must be in a
writing, signed by the Agent and the Guarantor.

          23.  THE GUARANTOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS GUARANTY,
THE LOAN DOCUMENTS OR ANY OTHER DOCUMENT OR INSTRUMENT NOW OR HEREAFTER EXECUTED
OR DELIVERED IN CONNECTION HEREWITH OR THEREWITH, OR (2) IN ANY WAY CONNECTED
WITH OR RELATED OR INCIDENTAL TO THIS GUARANTY AGREEMENT OR ANY OTHER DOCUMENT
OR INSTRUMENT NOW OR HEREAFTER EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE; AND THE GUARANTOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT AGENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTOR TO THE WAIVER
OF THE GUARANTOR'S RIGHT TO TRIAL BY JURY.
                                                                         _______

          2.   GRANT OF SECURITY INTEREST.  As security for the due and punctual
               --------------------------                                       
payment and performance of the Indebtedness and the Guaranteed Indebtedness in
accordance with the respective terms thereof, the Company, as debtor, hereby

the Banks, a security interest under the Uniform Commercial Code in and to any
and all of the Collateral.

          3.   STOCK CERTIFICATES AND STOCK POWERS.  Upon the execution and 
               -----------------------------------   
delivery of this Agreement, the Company has caused to be delivered to and

certificates and any other instruments evidencing the Collateral, together with

all cash proceeds of the Collateral and cash dividends received in respect of
the Collateral. The Agent shall have sole dominion and control over all items
and funds in the Cash Collateral Account and such items and funds may be

funds on deposit in the Cash Collateral Account to the payment of the
Indebtedness and the Guaranteed Indebtedness in order of application as set
forth in Section 11 hereof, whether on account of principal or interest or
otherwise as the Agent in its discretion may elect, until the Secured
Obligations are fully paid; and

any part or all of the Collateral registered in the name of the Agent or that of
its nominee, and the Company covenants that, upon the Agent's request, the

effect such registration.

The Agent may by written notice to the Company relinquish, either partially or
completely in accordance with any terms or conditions the Agent may set forth in
such notice, any or all rights the Agent may acquire pursuant hereto; provided,
                                                                      --------

- -------                                                                        
this Section 5 are solely to protect the interests of the Agent for the benefit

          (a)  The Company has and will have at all times good and marketable
title to the Collateral, free and clear of all liens, except for Permitted
Liens, and will defend such title against the claims and demands of all persons
whomsoever, except liens in favor of the Agent.  The Company assumes full
responsibility for taking any and all steps to preserve rights with respect to
the Collateral against all prior parties.

          (b)  The Pledged Shares and any other shares of capital stock included
in the Collateral have been duly authorized and validly issued, are fully paid
and nonassessable and are owned beneficially and of record by the Company.  The
Pledged Shares constitute all of the issued and outstanding capital stock of the
issuer thereof; provided, if the Pledged Shares include shares acquired after

the date of this Agreement pursuant to Permitted Business Combinations, the
shares may not constitute 100% of the outstanding capital stock of the issuer
thereof.

          (c)  Except as disclosed on Schedule 6, there are no shareholder,
partnership or other agreements or understandings with respect to the Pledged
Shares or any other securities

                                      -3-
<PAGE>
 
included in the Collateral; provided, if the Pledged Shares include shares
                            --------

Combinations, the Company may ask the Agent to accept additional agreements or
understandings.  The Agent, after consulting with the Banks, will not withhold
its consent unreasonably.

          (d)  Except as described on Schedule 6 and except to the extent
contained in Agreements consented to by the Banks pursuant to Section 6(c), the
Pledged Shares and any other securities included in the Collateral are free and
clear of any lien, option or right of others or restriction on transfer except
for the security interest granted to and created in favor of the Agent for the
benefit of the Banks hereunder and except to the extent that the transfer by the
Agent of such Collateral may be restricted by the Federal Securities Act of
1933, as amended, and applicable state securities laws.

          (e)  The Company will not take any action, or vote or omit to vote the
Pledged Shares or any other securities included in the Collateral in a manner
which would permit the issuer thereof to take or omit to take any action, the
taking or the omission of which might result in an alteration or impairment of
the Collateral or of this Agreement;

          (f)  The Company will not vote or omit to vote the Pledged Shares or
any other securities included in the Collateral in a manner inconsistent with
Section 7.2.14 of the Credit Agreement.

          (g)  There are no actions, suits, proceedings or investigations
pending or, to the knowledge of the Company, threatened which affect the
Collateral.

          (h)  The security interest granted to the Agent for the benefit of the
Banks pursuant to this Agreement constitutes and will continue to constitute a
Prior Security Interest under the Uniform Commercial Code as in effect in each
applicable jurisdiction or other applicable law, entitled to all the rights,
benefits and priorities provided by the Uniform Commercial Code or such law.
Upon the taking possession of the stock certificates or other certificates
evidencing all or part of the Collateral, all such action as is necessary or
advisable to establish such rights of the Agent will have been taken, and there
will be upon execution and delivery of this Agreement and such taking of
possession, no necessity for any further action in order to preserve, protect
and continue such rights.  All expenses in connection with such action has been
or will be paid by the Company.

          7.   TAXES AND CHARGES.  The Company will pay and discharge all taxes,
               -----------------                                                
levies and other impositions levied on any portion of the Collateral (except to
the extent only that such taxes, levies and other impositions shall not then be
due or shall be contested in good faith by appropriate proceedings diligently
conducted, provided that such reserves and other provisions as may be required
by GAAP have been duly made and recorded).  If the Company shall fail to do so,
the Agent may (but shall not be obligated to) pay such taxes, levies or
impositions for the account of the Company and may add the amount thereof to the
Indebtedness and the Guaranteed Indebtedness.

          8.   PRESERVATION AND PROTECTION OF SECURITY INTEREST.  The Company
               ------------------------------------------------              
will faithfully preserve and protect the Agent's security interest in the
Collateral as a Prior Security

                                      -4-
<PAGE>
 
Interest and will, at its own cost and expense, cause such security interest in
the Collateral to be perfected and continue perfected so long as the
Indebtedness and the Guaranteed Indebtedness or any portion thereof are
outstanding and unpaid.  For such purposes the Company will from time to time at
the request of the Agent (a) turn over physical possession to the Agent for the
benefit of the Banks of all Collateral which requires the Agent to have
possession thereof in order to perfect the Agent's security interest therein for
the benefit of the Banks and (b) file or record, or cause to be filed or
recorded, such instruments, documents and notices, including without limitation
financing statements and continuation statements, all as the Agent may deem
necessary or advisable from time to time in order to perfect and continue
perfected said security interests as Prior Security Interests.

          The Company will do all such other acts and things and will execute
and deliver all such other instruments and documents, including without
limitation further security agreements, pledges, endorsements, assignments and
notices, as the Agent may deem necessary or advisable from time to time in order
to perfect and preserve the priority of said security interest as a Prior
Security Interest in the Collateral.  The Agent, and its officers, employees and
authorized agents, or any of them, are hereby irrevocably appointed the
attorneys-in-fact of the Company (without requiring any of them to act as such),
such appointment being coupled with an interest, to do, at the Company's
expense, all acts and things which the Agent may deem necessary or advisable to
preserve, perfect and continue perfected the Agent's security interest in the
Collateral as a Prior Security Interest, including without limitation the
signing of financing, continuation or other similar statements and notices on
behalf of the Company.  In addition to the foregoing but not in limitation
thereof, the Company agrees that a carbon, photographic or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
any appropriate office in lieu thereof.

          The Agent shall be deemed to have exercised reasonable care in the
preservation and custody of such of the Collateral as may be in the Agent's
possession if the Agent takes such action for that purpose as the Company shall
request in writing, provided that such requested action shall not in the
exclusive judgment of the Agent impair the Agent's Prior Security Interest in
such Collateral or its rights in or the value of such Collateral, and provided
further that such written request is received by the Agent in sufficient time to
permit the Agent to take the requested action.

          9.   EVENTS OF DEFAULT.  The Company shall, at the option of the
               -----------------                                          
Agent, be in default under this Agreement upon the happening of any of the
following events or conditions (each, an "EVENT OF DEFAULT"):

          (a)  an Event of Default as defined in the Credit Agreement or any
other Loan Document;

          (b)  the failure of the Agent to have a Prior Security Interest in any
portion of the Collateral; or

          (c)  any indication or evidence received by the Agent that the Company
may have directly or indirectly been engaged in any type of activity which, in
the Agent's discretion,

                                      -5-
<PAGE>
 
might result in the forfeiture of any property of the Company to any
governmental entity, federal, state or local.
 
          10.  REMEDIES ON DEFAULT.  If any one or more of the Events of Default
               -------------------                                              
shall occur and be continuing or exist, the Agent for the benefit of the Banks
shall have the immediate right to take control of all or any part of the
Collateral and the proceeds thereof, with or without judicial process, and,
without demand of performance or notice (and if notice is required by Law, after
ten (10) days' prior written notice, which the Company agrees is a reasonable
time and manner for notice), or demand whosoever to the Company, all of which
are hereby expressly waived, and without advertisement, may proceed to exercise
one or more of the rights and remedies accorded a secured party by the Uniform
Commercial Code and otherwise by Law or by the terms of the Credit Agreement or
this Agreement or any other Loan Document.

          The Agent's rights and remedies shall include without limitation the
power for the benefit of the Banks to (i) transfer into the Agent's name or into
the name of its nominee or nominees all or any portion of the Pledged Shares or
other securities constituting part or all of the Collateral and thereafter
receive directly all cash and other dividends, distributions and payments made
on account of said stock or securities, vote the same, give all consents,
waivers and ratifications in respect thereof, and otherwise act with respect
thereto as though it were the absolute owner thereof, and (ii) sell all or any
portion of the Collateral at public or private sale at such place and time and
on such terms as the Agent may see fit.

          The Company recognizes that the Agent may be compelled to resort to
one or more private sales of any of the Pledged Shares or other securities
constituting part or all of the Collateral to a restricted group of purchasers
who will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Company acknowledges and agrees that any such private sale
(such sale or any public sale to be conducted in a commercially reasonable
manner) may result in prices and other terms less favorable to the seller than
if such sale were a public sale and, notwithstanding such circumstances, agrees
that any such private sale shall not, for such reason alone, be deemed to have
been made in a commercially unreasonable manner.  The Agent shall not be under
any obligation to delay a sale of any such shares or securities for the period
of time necessary to permit the issuer of such securities to register such
securities for public sale under the Federal Securities Act of 1933, as amended,
or under applicable state securities Laws, even if the issuer would agree to do
so.  At any sale or other disposition, the Agent may, to the extent permissible
under applicable Laws, purchase all any part of the Collateral, free from any
right of redemption on the part of the Company, which right is hereby waived and
released.

          11.  APPLICATION OF PROCEEDS.  Any Collateral or proceeds of the
               -----------------------                                    
Collateral held or realized upon at any time by the Agent or any of the Banks
and any debt (including all deposit accounts) in which the Agent or any of the
Banks has been granted a security interest pursuant to any of the Loan Documents
and which has been set off or applied by the Agent pursuant to any such Loan
Document, shall be applied in satisfaction of the Indebtedness and the
Guaranteed Indebtedness, in such order of application as the Agent shall
determine in its discretion if there has been an Event of Default and, if there
has not been an Event of Default, as determined by the Borrower and the Agent,
until the Indebtedness and the Guaranteed Indebtedness are fully paid, and
thereafter any balance shall be distributed as required by

                                      -6-
<PAGE>
 
applicable Law.  If the proceeds of the Collateral together with the proceeds of
any other collateral granted to the Agent by the Company for the benefit of the
Banks, and of any sales or dispositions thereof, shall be insufficient to pay
the amounts secured hereby, the Company shall be liable for the deficiency.

          12.  CHANGES IN WRITING.  No modification, amendment or waiver of any
               ------------------                                              
provision of this Agreement nor consent to any departure by the Company
therefrom, will in any event be effective unless the same is in writing and
signed by the Agent, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given.

          13.  PRESERVATION OF RIGHTS.  No delay or omission on the part of the
               ----------------------                                          
Agent to exercise any right or power arising hereunder will impair any such
right or power or be considered a waiver of any such right or power or any
acquiescence therein, nor will the action or inaction of the Agent impair any
right or power arising hereunder.  The Agent's rights and remedies hereunder are
cumulative and not exclusive of any other rights or remedies which the Agent
otherwise would have, whether under the Credit Agreement or any other Loan
Document, the Uniform Commercial Code, applicable Law or otherwise.

          14.  TAXES.  The Company agrees to pay upon demand any and all stamp,
               -----                                                           
document, transfer or recording taxes, and similar impositions payable or
hereafter determined to be payable in connection with this Agreement and agrees
to save the Agent and the Banks harmless from and against any and all present or
future claims or liabilities with respect to, or resulting from any delay in
paying or omission to pay, any such taxes or similar impositions.

          15.  PAYMENT OF EXPENSES.  At its option, the Agent may discharge
               -------------------                                         
taxes, liens, security interests or such other encumbrances as may attach to the
Collateral, may pay for required insurance on the Collateral and may pay for the
maintenance, appraisal or reappraisal, and preservation of the Collateral, as
determined by the Agent to be necessary.  The Company will reimburse the Agent
on demand for any payment so made or any expense incurred by the Agent pursuant
to the foregoing authorization, and the Collateral also will secure any advances
or payments so made or expenses so incurred by the Agent.

          16.  NOTICES.  All notices, demands, requests, consents, approvals and
               -------                                                          
other communications required or permitted hereunder must be in writing and will
be effective if made in conformity with Section 10.6 of the Credit Agreement.

          17.  SURVIVAL.  All representations, warranties, covenants and
               --------                                                 
agreements of the Company contained herein or made in connection herewith shall
survive the execution and delivery of this Agreement and shall continue in full
force and effect so long as any of the Credit Agreement and the other Loan
Documents is in effect, or any Indebtedness or the Guaranteed Indebtedness is
outstanding and until payment in full of all Indebtedness and the Guaranteed
Indebtedness hereunder and under the Credit Agreement and the other Loan
Documents.  The indemnity agreement contained in Section 21 of this Agreement
shall survive the termination of this Agreement.

          18.  GOVERNING LAW; VENUE.  The Uniform Commercial Code shall govern
               --------------------

Agent's security

                                      -7-

interest in the Collateral, and the rights, duties and obligations of the Agent
and the Company with respect thereto.  Except as provided by the immediately
preceding sentence, this Agreement shall be deemed to be a contract under the
laws of the Commonwealth of Pennsylvania and the execution and delivery thereof
and the terms and provisions shall be governed by and construed in accordance
with the laws of said Commonwealth.  The Company irrevocably consents to the
nonexclusive jurisdiction of the Court of Common Pleas of Allegheny County and
the United States District Court for the Western District of Pennsylvania, and
waives personal service of any and all process upon it and consents that all
such service of process be made by certified or registered mail directed to it
at the address provided for in the Guaranty and service so made shall be deemed
to be completed upon actual receipt thereof.  The Company waives any objection
to jurisdiction and venue of any action instituted against it as provided herein
and agrees not to assert any defense based on lack of jurisdiction or venue.

          19.  SUCCESSORS AND ASSIGNS.  This Agreement will be binding upon and
               ----------------------                                          
inure to the benefit of the Company and the Agent for the benefit of the Banks
and their respective heirs, executors, administrators, successors and assigns;
                                                                              
provided, however, that the Company may not assign this Agreement in whole or in
- --------  -------                                                               
part without the prior written consent of the Agent, and the Agent at any time
may assign this Agreement in whole or in part.

          20.  SEVERABILITY.  If any term, provision, or restriction of this
               ------------                                                 
Agreement is held to be invalid, void or unenforceable in any way in any
jurisdiction, the remainder of the terms, provisions, covenants and restrictions
of this Agreement shall remain in full force and effect in such jurisdiction and
shall in no way be affected, impaired or invalidated, and such invalidity,
voidness or unenforceability shall not affect the validity and enforceability of
such provision, covenant, or restriction in any other jurisdiction.  It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such which may be hereafter declared invalid, void or
unenforceable.

          21.  INDEMNITY.  The Company agrees to indemnify each of the Agent and
               ---------                                                        
the Banks, their directors, officers and employees and each legal entity, if
any, who controls the Agent or the Banks (the "INDEMNIFIED PARTIES") and to hold
each Indemnified Party harmless from and against any and all claims, damages,
losses, liabilities and expenses (including, without limitation, all fees of
counsel with whom any Indemnified Party may consult and all expenses of
litigation or preparation therefor) which any Indemnified Party may incur or
which may be asserted against any Indemnified Party as a result of the execution
of or performance under this Agreement; provided, however, that the foregoing
                                        --------  -------                    
indemnity agreement shall not apply to claims, damages, losses, liabilities and
expenses attributable to an Indemnified Party's gross negligence or willful
misconduct.  The indemnity agreement contained in this Section shall survive the
termination of this Agreement.  The Company may participate at its expense in
the defense of any such claim.

          22.  MARSHALLING; PAYMENTS SET ASIDE.  The Agent shall not be under
               -------------------------------                               
any obligation to marshall any assets in favor of the Company or any other
person or against or in payment of any or all of the Indebtedness or the
Guaranteed Indebtedness.  To the extent that the Company makes a payment or
payments to the Agent, or the Agent enforces its security interests, or the
Agent exercises its rights of setoff, and such payment or payments or the

                                      -8-
<PAGE>
 
proceeds of such enforcement or setoff or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or are required to be refunded, repaid or otherwise restored
to the Company, a trustee, receiver or any other person under any law, including
without limitation any bankruptcy law, state or federal law, common law or
equitable cause, then to the extent of any such restoration, the obligation or
part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.

          23.  ENTIRE AGREEMENT.  This Agreement (including the documents and
               ----------------                                              
instruments referred to herein) constitutes the entire agreement and supersedes
all other prior agreements and understandings, both written and oral, between
the parties with respect to the subject matter hereof.

          24.  CONTINUING VALIDITY OF GUARANTEED INDEBTEDNESS.  The agreements
               ----------------------------------------------                 
and obligations of the Company hereunder are continuing agreements and
obligations, and are absolute and unconditional irrespective of the genuineness,
validity or enforceability of any note or other instrument or instruments now or
hereafter evidencing the Indebtedness or the Guaranteed Indebtedness or any part
thereof or of the Credit Agreement, the Guaranty, this Agreement or other Loan
Document or any other agreement or agreements now or hereafter entered into by
the Agent for the benefit of the Banks or the Company pursuant to which the
Indebtedness or the Guaranteed Indebtedness or any part thereof is issued or of
any other circumstance which might otherwise constitute a legal or equitable
discharge of such agreements and obligations; without limitation upon the
foregoing, such agreements and obligations shall continue in full force and
effect as long as the Indebtedness or the Guaranteed Indebtedness or any part
thereof remains outstanding and unpaid and shall remain in full force and effect
without regard to and shall not be released, discharged or in any way affected
by (i) any renewal, refinancing or refunding of the Indebtedness or the
Guaranteed Indebtedness in whole or in part, (ii) any extension of the time of
any payment due under any note or instrument or instruments now or hereafter
evidencing the Indebtedness or the Guaranteed Indebtedness or any part thereof,
(iii) any compromise or settlement with respect to the Indebtedness or the
Guaranteed Indebtedness or any part thereof, or any forbearance or indulgence
extended to the Company, (iv) any amendment to or modification of the terms of
any instrument or instruments now or hereafter evidencing the Indebtedness or
the Guaranteed Indebtedness or any part thereof or any other agreement or
agreements now or hereafter entered into by the Agent and the Company pursuant
to which the Indebtedness or the Guaranteed Indebtedness or any part thereof is
issued or secured, (v) any substitution, exchange or release of, or failure to
preserve, perfect or protect, or other dealing in respect of, any property or
any security for the payment of the Indebtedness or the Guaranteed Indebtedness
or any part thereof, (vi) any bankruptcy, insolvency, arrangement, composition,
assignment for the benefit of creditors or similar proceeding commenced by or
against the Company, or (vii) any other matter or thing whatsoever whereby the
agreements and obligations of the Company hereunder or under the Credit
Agreement or any other Loan Document would or might otherwise be released or
discharged.

          25.  DEFEASANCE.  This Agreement shall terminate and be of no further
               ----------                                                      
force and effect, and the Agent shall return to the Company any Collateral in
the Agent's possession, upon satisfaction in full of the Indebtedness and the
Guaranteed Indebtedness, the expiration of

                                     -9-0
<PAGE>
 
the Letters of Credit without a draw having been made, and the termination of
the Banks' commitment to lend.  Notwithstanding the foregoing provisions of this
Section 25, the indemnity agreement contained in Section 21 of this Agreement
shall survive the termination of this Agreement.

          26.  COUNTERPARTS.  This Agreement may be executed in any number of
               ------------

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

failure to perform or observe any covenants set forth in this Agreement shall
constitute a breach of this Agreement and may give rise to an Event of Default
notwithstanding the fact that the failure to perform or observe such covenant
may be attributable to the requirements of any Official Body.

          2.   GRANT OF SECURITY INTEREST.  As security for the due and punctual
               --------------------------                                       
payment and performance of the Indebtedness and the Guaranteed Indebtedness in
accordance with the respective terms thereof, the Company, as debtor, hereby

the Banks, a security interest under the Uniform Commercial Code in and to any
and all of the Collateral.

          3.   STOCK CERTIFICATES AND STOCK POWERS.  Upon the execution and
               -----------------------------------
delivery of this Agreement, the Company has caused to be delivered to and
deposited with the Agent or its nominee or nominees, in pledge, stock
certificates and any other instruments evidencing the Collateral, together with
undated stock powers signed in blank by the Company.

          4.   VOTING RIGHTS.  Notwithstanding the security interest in the

Collateral granted to and created in favor of the Agent for the benefit of the
Banks, the Company shall have the right, until the Agent forecloses upon the
Collateral, to exercise all voting and other shareholders' rights with respect
to the Collateral, subject to Section 5 hereof.

          5.   RIGHTS OF AGENT TO COLLATERAL.  The Agent may at its option and
               -----------------------------   
at any time and from time to time (except as provided in subsections (c) and
(d)), without notice to or consent of the Company, whether or not an Event of
Default (as hereinafter defined) has occurred or exists, do any or all of the
following:

          (a)  Take such action as the Agent deems appropriate to maintain,
protect and insure the Collateral, to attach, perfect, continue, preserve and
protect the Agent's Prior Security Interest in the Collateral, to perform, keep,
observe and render true and correct any and all

                                      -2-
<PAGE>

          (c)  After an Event of Default has occurred and is continuing, cause
to be opened and maintained an interest bearing deposit account ("CASH

all cash proceeds of the Collateral and cash dividends received in respect of
the Collateral. The Agent shall have sole dominion and control over all items
and funds in the Cash Collateral Account and such items and funds may be
withdrawn only by the Agent, it being the intention of the parties hereto that
the Company shall have no control over or withdrawal rights in respect of the
Cash Collateral Account. The Agent, upon the vote of all the Banks and upon the
written request by the Company to the Agent, may release to the Company at any
time after 2:00 o'clock p.m., Pittsburgh time on the first business day
following the date of such vote and request, all or any part of the collected
funds deposited in the Cash Collateral Account for application to the
outstanding principal balance of the Indebtedness and the Guaranteed
Indebtedness. Notwithstanding any such request, the Agent shall have the right
at any time and from time to time to apply all or any part of the collected
funds on deposit in the Cash Collateral Account to the payment of the
Indebtedness and the Guaranteed Indebtedness in order of application as set
forth in Section 11 hereof, whether on account of principal or interest or
otherwise as the Agent in its discretion may elect, until the Secured
Obligations are fully paid; and

          (d)  After an Event of Default has occurred and is continuing, have
any part or all of the Collateral registered in the name of the Agent or that of
its nominee, and the Company covenants that, upon the Agent's request, the
Company will cause the issuer, transfer agent or registrar of such Collateral to
effect such registration.

The Agent may by written notice to the Company relinquish, either partially or
completely in accordance with any terms or conditions the Agent may set forth in
such notice, any or all rights the Agent may acquire pursuant hereto; provided,
                                                                      -------- 
however, that the powers conferred on the Agent for the benefit of the Banks by
- -------                                                                        
this Section 5 are solely to protect the interests of the Agent for the benefit
of the Banks in the Collateral and shall not impose on the Agent any duty to
exercise such powers.

          6.   REPRESENTATIONS AND WARRANTIES.
               ------------------------------ 

          (a)  The Company has and will have at all times good and marketable
title to the Collateral, free and clear of all liens, except for Permitted
Liens, and will defend such title against the claims and demands of all persons
whomsoever, except liens in favor of the Agent.  The Company assumes full
responsibility for taking any and all steps to preserve rights with respect to
the Collateral against all prior parties.

          (b)  The Pledged Shares and any other shares of capital stock included
in the Collateral have been duly authorized and validly issued, are fully paid
and nonassessable and are owned beneficially and of record by the Company.  With
the exception of the shares of Young's

                                      -3-
<PAGE>
 
I.V. Therapy, Inc. which constitute 80% of the issued and outstanding capital
stock thereof, the Pledged Shares constitute all of the issued and outstanding
capital stock of the issuer thereof; provided, if the Pledged Shares include
                                     --------                               
shares acquired after the date of this Agreement pursuant to Permitted Business
Combinations, the shares may not constitute 100% of the outstanding capital
stock of the issuer thereof.

          (c)  Except as disclosed on Schedule 6, there are no shareholder,
partnership or other agreements or understandings with respect to the Pledged
Shares or any other securities included in the Collateral; provided, if the
                                                           --------        
Pledged Shares include shares acquired after the date of this Agreement pursuant
to Permitted Business Combinations, the Company may ask the Agent to accept
additional agreements or understandings.  The Agent, after consulting with the
Banks, will not withhold its consent unreasonably.

          (d)  Except as disclosed on Schedule 6 and except to the extent
contained in Agreements consented to by the Banks pursuant to Section 6(c), the
Pledged Shares and any other securities included in the Collateral are free and
clear of any lien, option or right of others or restriction on transfer except
for the security interest granted to and created in favor of the Agent for the
benefit of the Banks hereunder and except to the extent that the transfer by the
Agent of such Collateral may be restricted by the Federal Securities Act of
1933, as amended, and applicable state securities laws.

          (e)  The Company will not take any action, or vote or omit to vote the
Pledged Shares or any other securities included in the Collateral in a manner
which would permit the issuer thereof to take or omit to take any action, the
taking or the omission of which might result in an alteration or impairment of
the Collateral or of this Agreement;

          (f)  The Company will not vote or omit to vote the Pledged Shares or
any other securities included in the Collateral in a manner inconsistent with
Section 7.2.14 of the Credit Agreement.

          (g)  There are no actions, suits, proceedings or investigations
pending or, to the knowledge of the Company, threatened which affect the
Collateral.

          (h)  The security interest granted to the Agent for the benefit of the
Banks pursuant to this Agreement constitutes and will continue to constitute a
Prior Security Interest under the Uniform Commercial Code as in effect in each
applicable jurisdiction or other applicable law, entitled to all the rights,
benefits and priorities provided by the Uniform Commercial Code or such law.
Upon the taking possession of the stock certificates or other certificates
evidencing all or part of the Collateral, all such action as is necessary or
advisable to establish such rights of the Agent will have been taken, and there
will be upon execution and delivery of this Agreement and such taking of
possession, no necessity for any further action in order to preserve, protect
and continue such rights.  All expenses in connection with such action has been
or will be paid by the Company.

          7.   TAXES AND CHARGES.  The Company will pay and discharge all taxes,
               -----------------                                                
levies and other impositions levied on any portion of the Collateral (except to
the extent only that such taxes, levies and other impositions shall not then be
due or shall be contested in good faith

                                      -4-
<PAGE>
 
by appropriate proceedings diligently conducted, provided that such reserves and
other provisions as may be required by GAAP have been duly made and recorded).
If the Company shall fail to do so, the Agent may (but shall not be obligated
to) pay such taxes, levies or impositions for the account of the Company and may
add the amount thereof to the Indebtedness and the Guaranteed Indebtedness.

          8.   PRESERVATION AND PROTECTION OF SECURITY INTEREST.  The Company
               ------------------------------------------------              
will faithfully preserve and protect the Agent's security interest in the
Collateral as a Prior Security Interest and will, at its own cost and expense,
cause such security interest in the Collateral to be perfected and continue
perfected so long as the Indebtedness and the Guaranteed Indebtedness or any
portion thereof are outstanding and unpaid.  For such purposes the Company will
from time to time at the request of the Agent (a) turn over physical possession
to the Agent for the benefit of the Banks of all Collateral which requires the
Agent to have possession thereof in order to perfect the Agent's security
interest therein for the benefit of the Banks and (b) file or record, or cause
to be filed or recorded, such instruments, documents and notices, including
without limitation financing statements and continuation statements, all as the
Agent may deem necessary or advisable from time to time in order to perfect and
continue perfected said security interests as Prior Security Interests.

          The Company will do all such other acts and things and will execute
and deliver all such other instruments and documents, including without
limitation further security agreements, pledges, endorsements, assignments and
notices, as the Agent may deem necessary or advisable from time to time in order
to perfect and preserve the priority of said security interest as a Prior
Security Interest in the Collateral.  The Agent, and its officers, employees and
authorized agents, or any of them, are hereby irrevocably appointed the
attorneys-in-fact of the Company (without requiring any of them to act as such),
such appointment being coupled with an interest, to do, at the Company's
expense, all acts and things which the Agent may deem necessary or advisable to
preserve, perfect and continue perfected the Agent's security interest in the
Collateral as a Prior Security Interest, including without limitation the
signing of financing, continuation or other similar statements and notices on
behalf of the Company.  In addition to the foregoing but not in limitation
thereof, the Company agrees that a carbon, photographic or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
any appropriate office in lieu thereof.

          The Agent shall be deemed to have exercised reasonable care in the
preservation and custody of such of the Collateral as may be in the Agent's
possession if the Agent takes such action for that purpose as the Company shall
request in writing, provided that such requested action shall not in the
exclusive judgment of the Agent impair the Agent's Prior Security Interest in
such Collateral or its rights in or the value of such Collateral, and provided
further that such written request is received by the Agent in sufficient time to
permit the Agent to take the requested action.

          9.   EVENTS OF DEFAULT.  The Company shall, at the option of the
               -----------------                                          
Agent, be in default under this Agreement upon the happening of any of the
following events or conditions (each, an "EVENT OF DEFAULT"):

                                      -5-
<PAGE>
 
          (a)  an Event of Default as defined in the Credit Agreement or any
other Loan Document;

          (b)  the failure of the Agent to have a Prior Security Interest in any
portion of the Collateral; or

          (c)  any indication or evidence received by the Agent that the Company
may have directly or indirectly been engaged in any type of activity which, in
the Agent's discretion, might result in the forfeiture of any property of the
Company to any governmental entity, federal, state or local.
 
          10.  REMEDIES ON DEFAULT.  If any one or more of the Events of Default
               -------------------                                              
shall occur and be continuing or exist, the Agent for the benefit of the Banks
shall have the immediate right to take control of all or any part of the
Collateral and the proceeds thereof, with or without judicial process, and,
without demand of performance or notice (and if notice is required by Law, after
ten (10) days' prior written notice, which the Company agrees is a reasonable
time and manner for notice), or demand whosoever to the Company, all of which
are hereby expressly waived, and without advertisement, may proceed to exercise
one or more of the rights and remedies accorded a secured party by the Uniform
Commercial Code and otherwise by Law or by the terms of the Credit Agreement or
this Agreement or any other Loan Document.

          The Agent's rights and remedies shall include without limitation the
power for the benefit of the Banks to (i) transfer into the Agent's name or into
the name of its nominee or nominees all or any portion of the Pledged Shares or
other securities constituting part or all of the Collateral and thereafter
receive directly all cash and other dividends, distributions and payments made
on account of said stock or securities, vote the same, give all consents,
waivers and ratifications in respect thereof, and otherwise act with respect
thereto as though it were the absolute owner thereof, and (ii) sell all or any
portion of the Collateral at public or private sale at such place and time and
on such terms as the Agent may see fit.

          The Company recognizes that the Agent may be compelled to resort to
one or more private sales of any of the Pledged Shares or other securities
constituting part or all of the Collateral to a restricted group of purchasers
who will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Company acknowledges and agrees that any such private sale
(such sale or any public sale to be conducted in a commercially reasonable
manner) may result in prices and other terms less favorable to the seller than
if such sale were a public sale and, notwithstanding such circumstances, agrees
that any such private sale shall not, for such reason alone, be deemed to have
been made in a commercially unreasonable manner.  The Agent shall not be under
any obligation to delay a sale of any such shares or securities for the period
of time necessary to permit the issuer of such securities to register such
securities for public sale under the Federal Securities Act of 1933, as amended,
or under applicable state securities Laws, even if the issuer would agree to do
so.  At any sale or other disposition, the Agent may, to the extent permissible
under applicable Laws, purchase all any part of the Collateral, free from any
right of redemption on the part of the Company, which right is hereby waived and
released.

                                      -6-

          11.  APPLICATION OF PROCEEDS.  Any Collateral or proceeds of the
               -----------------------                                    
Collateral held or realized upon at any time by the Agent or any of the Banks
and any debt (including all deposit accounts) in which the Agent or any of the
Banks has been granted a security interest pursuant to any of the Loan Documents
and which has been set off or applied by the Agent pursuant to any such Loan
Document, shall be applied in satisfaction of the Indebtedness and the
Guaranteed Indebtedness, in such order of application as the Agent shall
determine in its discretion if there has been an Event of Default and, if there
has not been an Event of Default, as determined by the Borrower and the Agent,
until the Indebtedness and the Guaranteed Indebtedness are fully paid, and
thereafter any balance shall be distributed as required by applicable Law.  If
the proceeds of the Collateral together with the proceeds of any other
collateral granted to the Agent by the Company for the benefit of the Banks, and
of any sales or dispositions thereof, shall be insufficient to pay the amounts
secured hereby, the Company shall be liable for the deficiency.

          12.  CHANGES IN WRITING.  No modification, amendment or waiver of any
               ------------------                                              
provision of this Agreement nor consent to any departure by the Company
therefrom, will in any event be effective unless the same is in writing and
signed by the Agent, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given.

          13.  PRESERVATION OF RIGHTS.  No delay or omission on the part of the
               ----------------------                                          
Agent to exercise any right or power arising hereunder will impair any such
right or power or be considered a waiver of any such right or power or any
acquiescence therein, nor will the action or inaction of the Agent impair any
right or power arising hereunder.  The Agent's rights and remedies hereunder are
cumulative and not exclusive of any other rights or remedies which the Agent
otherwise would have, whether under the Credit Agreement or any other Loan
Document, the Uniform Commercial Code, applicable Law or otherwise.

          14.  TAXES.  The Company agrees to pay upon demand any and all stamp,
               -----                                                           
document, transfer or recording taxes, and similar impositions payable or
hereafter determined to be payable in connection with this Agreement and agrees
to save the Agent and the Banks harmless from and against any and all present or
future claims or liabilities with respect to, or resulting from any delay in
paying or omission to pay, any such taxes or similar impositions.

          15.  PAYMENT OF EXPENSES.  At its option, the Agent may discharge
               -------------------                                         
taxes, liens, security interests or such other encumbrances as may attach to the
Collateral, may pay for required insurance on the Collateral and may pay for the
maintenance, appraisal or reappraisal, and preservation of the Collateral, as
determined by the Agent to be necessary.  The Company will reimburse the Agent
on demand for any payment so made or any expense incurred by the Agent pursuant
to the foregoing authorization, and the Collateral also will secure any advances
or payments so made or expenses so incurred by the Agent.

          16.  NOTICES.  All notices, demands, requests, consents, approvals and
               -------                                                          
other communications required or permitted hereunder must be in writing and will
be effective if made in conformity with Section 10.6 of the Credit Agreement.

          17.  SURVIVAL.  All representations, warranties, covenants and
               --------                                                 
agreements of the Company contained herein or made in connection herewith shall

full of all Indebtedness and the Guaranteed Indebtedness hereunder and under the
Credit Agreement and the other Loan Documents.  The indemnity agreement
contained in Section 21 of this Agreement shall survive the termination of this
Agreement.

          18.  GOVERNING LAW; VENUE.  The Uniform Commercial Code shall govern

conducted, provided that such reserves and other provisions as may be required
by GAAP have been duly made and recorded).  If the Company shall fail to do so,
the Agent may (but shall not be obligated to) pay such taxes, levies or
impositions for the account of the Company and may add the amount thereof to the
Indebtedness and the Guaranteed Indebtedness.

          8.   PRESERVATION AND PROTECTION OF SECURITY INTEREST.  The Company
               ------------------------------------------------              
will faithfully preserve and protect the Agent's security interest in the
Collateral as a Prior Security Interest and will, at its own cost and expense,
cause such security interest in the Collateral to be perfected and continue
perfected so long as the Indebtedness and the Guaranteed Indebtedness or any
portion thereof are outstanding and unpaid.  For such purposes the Company will
from time to time at the request of the Agent (a) turn over physical possession
to the Agent for the benefit of the Banks of all Collateral which requires the
Agent to have possession thereof in

                                      -4-
<PAGE>
 
order to perfect the Agent's security interest therein for the benefit of the
Banks and (b) file or record, or cause to be filed or recorded, such
instruments, documents and notices, including without limitation financing
statements and continuation statements, all as the Agent may deem necessary or
advisable from time to time in order to perfect and continue perfected said
security interests as Prior Security Interests.

          The Company will do all such other acts and things and will execute
and deliver all such other instruments and documents, including without
limitation further security agreements, pledges, endorsements, assignments and
notices, as the Agent may deem necessary or advisable from time to time in order
to perfect and preserve the priority of said security interest as a Prior
Security Interest in the Collateral.  The Agent, and its officers, employees and
authorized agents, or any of them, are hereby irrevocably appointed the
attorneys-in-fact of the Company (without requiring any of them to act as such),
such appointment being coupled with an interest, to do, at the Company's
expense, all acts and things which the Agent may deem necessary or advisable to
preserve, perfect and continue perfected the Agent's security interest in the
Collateral as a Prior Security Interest, including without limitation the
signing of financing, continuation or other similar statements and notices on
behalf of the Company.  In addition to the foregoing but not in limitation
thereof, the Company agrees that a carbon, photographic or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
any appropriate office in lieu thereof.

          The Agent shall be deemed to have exercised reasonable care in the
preservation and custody of such of the Collateral as may be in the Agent's
possession if the Agent takes such action for that purpose as the Company shall
request in writing, provided that such requested action shall not in the
exclusive judgment of the Agent impair the Agent's Prior Security Interest in
such Collateral or its rights in or the value of such Collateral, and provided
further that such written request is received by the Agent in sufficient time to
permit the Agent to take the requested action.

          9.   EVENTS OF DEFAULT.  The Company shall, at the option of the
               -----------------                                          
Agent, be in default under this Agreement upon the happening of any of the
following events or conditions (each, an "EVENT OF DEFAULT"):

               (a)  an Event of Default as defined in the Credit Agreement or
any other Loan Document;

               (b)  the failure of the Agent to have a Prior Security Interest
in any portion of the Collateral; or

               (c)  any indication or evidence received by the Agent that the
Company may have directly or indirectly been engaged in any type of activity
which, in the Agent's discretion, might result in the forfeiture of any property
of the Company to any governmental entity, federal, state or local.
 
          10.  REMEDIES ON DEFAULT.  If any one or more of the Events of Default
               -------------------                                              
shall occur and be continuing or exist, the Agent for the benefit of the Banks
shall have the immediate right to take control of all or any part of the
Collateral and the proceeds thereof, with or without

                                      -5-
<PAGE>
 
judicial process, and, without demand of performance or notice (and if notice is
required by Law, after ten (10) days' prior written notice, which the Company
agrees is a reasonable time and manner for notice), or demand whosoever to the
Company, all of which are hereby expressly waived, and without advertisement,
may proceed to exercise one or more of the rights and remedies accorded a
secured party by the Uniform Commercial Code and otherwise by Law or by the
terms of the Credit Agreement or this Agreement or any other Loan Document.

          The Agent's rights and remedies shall include without limitation the
power for the benefit of the Banks to (i) transfer into the Agent's name or into
the name of its nominee or nominees all or any portion of the Pledged Shares or
other securities constituting part or all of the Collateral and thereafter
receive directly all cash and other dividends, distributions and payments made
on account of said stock or securities, vote the same, give all consents,
waivers and ratifications in respect thereof, and otherwise act with respect
thereto as though it were the absolute owner thereof, and (ii) sell all or any
portion of the Collateral at public or private sale at such place and time and
on such terms as the Agent may see fit.

          The Company recognizes that the Agent may be compelled to resort to
one or more private sales of any of the Pledged Shares or other securities
constituting part or all of the Collateral to a restricted group of purchasers
who will be obliged to agree, among other things, to acquire such securities for
their own account for investment and not with a view to the distribution or
resale thereof.  The Company acknowledges and agrees that any such private sale
(such sale or any public sale to be conducted in a commercially reasonable
manner) may result in prices and other terms less favorable to the seller than
if such sale were a public sale and, notwithstanding such circumstances, agrees
that any such private sale shall not, for such reason alone, be deemed to have
been made in a commercially unreasonable manner.  The Agent shall not be under
any obligation to delay a sale of any such shares or securities for the period
of time necessary to permit the issuer of such securities to register such
securities for public sale under the Federal Securities Act of 1933, as amended,
or under applicable state securities Laws, even if the issuer would agree to do
so.  At any sale or other disposition, the Agent may, to the extent permissible
under applicable Laws, purchase all any part of the Collateral, free from any
right of redemption on the part of the Company, which right is hereby waived and
released.

          11.  APPLICATION OF PROCEEDS.  Any Collateral or proceeds of the
               -----------------------                                    
Collateral held or realized upon at any time by the Agent or any of the Banks
and any debt (including all deposit accounts) in which the Agent or any of the
Banks has been granted a security interest pursuant to any of the Loan Documents
and which has been set off or applied by the Agent pursuant to any such Loan
Document, shall be applied in satisfaction of the Indebtedness and the
Guaranteed Indebtedness, in such order of application as the Agent shall
determine in its discretion if there has been an Event of Default and, if there
has not been an Event of Default, as determined by the Borrower and the Agent,
until the Indebtedness and the Guaranteed Indebtedness are fully paid, and
thereafter any balance shall be distributed as required by applicable Law.  If
the proceeds of the Collateral together with the proceeds of any other
collateral granted to the Agent by the Company for the benefit of the Banks, and
of any sales or dispositions thereof, shall be insufficient to pay the amounts
secured hereby, the Company shall be liable for the deficiency.

                                      -6-
<PAGE>
 
          12.  CHANGES IN WRITING.  No modification, amendment or waiver of any
               ------------------                                              
provision of this Agreement nor consent to any departure by the Company
therefrom, will in any event be effective unless the same is in writing and
signed by the Agent, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given.

          13.  PRESERVATION OF RIGHTS.  No delay or omission on the part of the
               ----------------------                                          
Agent to exercise any right or power arising hereunder will impair any such
right or power or be considered a waiver of any such right or power or any
acquiescence therein, nor will the action or inaction of the Agent impair any
right or power arising hereunder.  The Agent's rights and remedies hereunder are
cumulative and not exclusive of any other rights or remedies which the Agent
otherwise would have, whether under the Credit Agreement or any other Loan
Document, the Uniform Commercial Code, applicable Law or otherwise.

          14.  TAXES.  The Company agrees to pay upon demand any and all stamp,
               -----                                                           
document, transfer or recording taxes, and similar impositions payable or
hereafter determined to be payable in connection with this Agreement and agrees
to save the Agent and the Banks harmless from and against any and all present or
future claims or liabilities with respect to, or resulting from any delay in
paying or omission to pay, any such taxes or similar impositions.

          15.  PAYMENT OF EXPENSES.  At its option, the Agent may discharge
               -------------------                                         
taxes, liens, security interests or such other encumbrances as may attach to the
Collateral, may pay for required insurance on the Collateral and may pay for the
maintenance, appraisal or reappraisal, and preservation of the Collateral, as
determined by the Agent to be necessary.  The Company will reimburse the Agent
on demand for any payment so made or any expense incurred by the Agent pursuant
to the foregoing authorization, and the Collateral also will secure any advances
or payments so made or expenses so incurred by the Agent.

          16.  NOTICES.  All notices, demands, requests, consents, approvals and
               -------

shall survive the termination of this Agreement.

          18.  GOVERNING LAW; VENUE.  The Uniform Commercial Code shall govern
               --------------------                                           
the attachment, perfection and the effect of attachment and perfection of the
Agent's security interest in the Collateral, and the rights, duties and
obligations of the Agent and the Company with respect thereto.  Except as
provided by the immediately preceding sentence, this Agreement shall be deemed
to be a contract under the laws of the Commonwealth of Pennsylvania and the
execution and delivery thereof and the terms and provisions shall be governed by
and construed in accordance with the laws of said Commonwealth.  The Company
irrevocably consents to the nonexclusive jurisdiction of the Court of Common
Pleas of Allegheny County and the United States District Court for the Western
District of Pennsylvania, and waives personal service of any and all process
upon it and consents that all such service of process be made by certified or
registered mail directed to it at the address provided for in the Guaranty and
service so made shall be deemed to be completed upon actual receipt thereof.
The Company waives any objection to jurisdiction and venue of any action
instituted against it as provided herein and agrees not to assert any defense
based on lack of jurisdiction or venue.

          19.  SUCCESSORS AND ASSIGNS.  This Agreement will be binding upon and

provided, however, that the Company may not assign this Agreement in whole or in

Agreement is held to be invalid, void or unenforceable in any way in any
jurisdiction, the remainder of the terms, provisions, covenants and restrictions
of this Agreement shall remain in full force and effect in such jurisdiction and
shall in no way be affected, impaired or invalidated, and such invalidity,
voidness or unenforceability shall not affect the validity and enforceability of
such provision, covenant, or restriction in any other jurisdiction.  It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such which may be hereafter declared invalid, void or
unenforceable.

               ---------

losses, liabilities and expenses (including, without limitation, all fees of
counsel with whom any Indemnified Party may consult and all expenses of
litigation or preparation therefor) which any Indemnified Party may incur or
which may be asserted against any Indemnified Party as a result of the execution

or otherwise restored to the Company, a trustee, receiver or any other person
under any law, including without limitation any bankruptcy law, state or federal
law, common law or equitable cause, then to the extent of any such restoration,

revived and continued in full force and effect as if such payment had not been
made or such enforcement or setoff had not occurred.

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

thereof remains outstanding and unpaid and shall remain in full force and effect

by (i) any renewal, refinancing or refunding of the Indebtedness or the
Guaranteed Indebtedness in whole or in part, (ii) any extension of the time of

the Guaranteed Indebtedness or any part thereof or any other agreement or
agreements now or hereafter entered into by the Agent and the Company pursuant

any security for the payment of the Indebtedness or the Guaranteed Indebtedness
or any part thereof, (vi) any bankruptcy, insolvency, arrangement, composition,
assignment for the benefit of creditors or similar proceeding commenced by or
against the Company, or (vii) any other matter or thing whatsoever whereby the
agreements and obligations of the Company hereunder or under the Credit
Agreement or any other Loan Document would or might otherwise be released or
discharged.

applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements

rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the
               ----------------

ensure maintenance of quality standards for such products and services. The time
and frequency of such inspections shall be consistent with those in Section 7.1
of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United

nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------

shall be cumulative and may be exercised singularly or concurrently.  The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

covenants and conditions hereof, shall be binding upon and inure to the benefit

     NOW, THEREFORE, in consideration of the foregoing premises, and intending
to be legally bound hereby, Assignor and Agent, on behalf of the Banks, hereby
agree as follows:
 
          1.   Definition of Terms Used Herein.  All capitalized terms not

Agreement.

          2.   Assignment and Security Interest.  As confirmation of the
               --------------------------------                         
security interest granted by Assignor under the Security Agreement to secure the

applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark

rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the
               ----------------                                            
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services.  The
time and frequency of such inspections shall be consistent with those in Section
7.1 of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement

Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------

shall be cumulative and may be exercised singularly or concurrently.  The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,

covenants and conditions hereof, shall be binding upon and inure to the benefit

               SECURITY INTEREST IN INTELLECTUAL PROPERTY RIGHTS


     THIS COLLATERAL ASSIGNMENT OF AND RATIFICATION OF SECURITY INTEREST IN
INTELLECTUAL PROPERTY RIGHTS (this "INSTRUMENT") is entered into this 23rd day
of December, 1996 by and between PHARMACY I.V. ASSOCIATES, INC., a Missouri

Pennsylvania 15222-2709. All terms capitalized but not otherwise defined herein
shall have the meanings ascribed to such terms in the Credit Agreement (as
hereinafter defined), unless the context otherwise requires.

     WHEREAS, the Assignor, its subsidiaries, the Agent and the Banks have
entered into that certain Credit Agreement of even date herewith (as the same
may be amended, modified, supplemented or restated from time to time, the
"CREDIT AGREEMENT"), pursuant to which the Banks have agreed to extend to the
Company, upon the terms and subject to the conditions set forth therein, a

     WHEREAS, the Assignor is the owner of all right, title and interest in, to
and under the intellectual property rights as set forth on the attached Schedule
A.

     WHEREAS, the Agent and the Assignor have entered into a Security Agreement
of even date herewith (as such agreement may be amended from time to time
hereafter, the "Security Agreement"), pursuant to which the Assignor granted to
the Agent a security interest in certain Collateral (as defined in the Security
Agreement) of Assignor, including but not limited to Assignor's General
Intangibles (as defined in the Security Agreement) which include, but are not
limited to, the intellectual property set forth on Schedule A hereto, as
security for the payment or performance of Assignor's Secured Obligations (as
defined in the Security Agreement), and pursuant to which the Assignor therein
agreed to execute and cause to be filed all such further instruments and
documents as Agent may request for preserving the security interest.

     WHEREAS, the Agent has requested that the Assignor execute and deliver this
Instrument for the purpose of collaterally assigning its interests in, and
placing in the public record of the United States Patent and Trademark Office
the collateral assignment granted pursuant hereto to the Agent in, certain of
the Assignor's Collateral for the benefit of the Banks.
<PAGE>
 
     NOW, THEREFORE, in consideration of the foregoing premises, and intending
to be legally bound hereby, Assignor and Agent, on behalf of the Banks, hereby
agree as follows:
 
          1.   Definition of Terms Used Herein.  All capitalized terms not
               -------------------------------  
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

          2.   Assignment and Security Interest.  As confirmation of the
security interest granted by Assignor under the Security Agreement to secure the
complete and timely satisfaction of all Secured Obligations, Assignor hereby
ratifies the creation and grant of the security interest in, and further, to
secure the complete and timely satisfaction of all Secured Obligations, Assignor
does hereby hypothecate (subject to paragraph 6 hereof), as collateral security,
to the Agent: (i) the United States patent and patent applications owned by
Assignor, all reissue, divisional, continuation, or continuation-in-part patent
applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark
applications, trademarks (whether registered, unregistered or for which an
application to register has been filed), service mark applications, service
marks (whether registered, unregistered or for which an application to register
has been filed) and tradenames, together with the goodwill of the business
related thereto; including without limitation all renewals thereof and all
proceeds (such as license royalties or proceeds of infringement suits), and all
rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the
               ----------------    
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services. The time
and frequency of such inspections shall be consistent with those in Section 7.1
of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement
on any of the Patents, or shall obtain rights in any United States or foreign
trademark, service mark or tradename or any registrations or applications for
registration thereof, the provisions of paragraph 2 (except for the Schedule
which will contain only registered Patents and Marks) shall automatically apply
thereto and Assignor shall give to the Agent prompt notice thereof in writing.

          5.   Modification by Agent.  Assignor authorizes the Agent to modify
               ---------------------                                          
this Instrument by amending Schedule A to include all federally registered
Patents and Marks which hereafter fall within the scope of paragraph 2 or
paragraph 4 hereof.

          6.   Retention of Rights.  Unless and until there shall have occurred

and be continuing an Event of Default, as defined in the Credit Agreement, the
Assignor shall retain the legal and equitable title to the Patents and the Marks
and shall have the right to use the Patents and the Marks in the ordinary course
of its business.  Assignor agrees, except as provided in the Credit Agreement,
not to sell or assign its interest in, or grant any license under the Patents or
Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------                  
Default shall have occurred and be continuing under either the Credit Agreement
or the Security Agreement, the Agent shall have all those rights and remedies
given it under the Security Agreement and those allowed by law.

          8.   Release of Interest.  At such time as Assignor shall completely
               -------------------                                            
satisfy all of the Secured Obligations, Agent shall execute and deliver to
Assignor all deeds, assignments and other instruments as may be necessary or
proper to release its interests in and to the Patents and Marks subject to any
disposition thereof which may have been made by the Agent pursuant to the
Security Agreement or hereto.

          9.   Cumulative Rights; Confirmation of Rights and Obligations Under
               ---------------------------------------------------------------
Security Agreement.  All of the Agent's rights and remedies with respect to the
- ------------------                                                             
Patents and Marks, whether established hereby, the Security Agreement or by law
shall be cumulative and may be exercised singularly or concurrently.  The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,
               -------------------------------                                  
covenants and conditions hereof, shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, except that
the Assignor shall not be permitted to assign this Instrument or any interest
herein or in the Collateral, or any part thereof, or otherwise pledge, encumber
or grant any option with respect to the Collateral, or any part thereof, or any
cash or property held by the Agent as Collateral under this Instrument, except
as contemplated by the Security Agreement or the Credit Agreement.

          11.  Governing Law.  This Instrument shall be construed in accordance
               -------------                                                   
with and governed by the laws of the Commonwealth of Pennsylvania, exclusive of
its rules on choice of law.

writing and given as provided in Section 10.6 of the Credit Agreement in the
case of the Assignor or the Agent.

          13.  Severability.  In case any one or more of the provisions

respect, the validity, legality and enforceability of the remaining provisions
contained herein shall not in any way be affected or impaired.

          14.  Section Headings.  Section headings used herein are for
               ----------------

taken together, shall constitute but one instrument.

                 COLLATERAL ASSIGNMENT OF AND RATIFICATION OF
               SECURITY INTEREST IN INTELLECTUAL PROPERTY RIGHTS


     THIS COLLATERAL ASSIGNMENT OF AND RATIFICATION OF SECURITY INTEREST IN
INTELLECTUAL PROPERTY RIGHTS (this "INSTRUMENT") is entered into this 23rd day
of December, 1996 by and between YOUNG'S I.V. THERAPY, INC., a Pennsylvania

Pennsylvania 15222-2709. All terms capitalized but not otherwise defined herein
shall have the meanings ascribed to such terms in the Credit Agreement (as
hereinafter defined), unless the context otherwise requires.

     WHEREAS, the Assignor, its subsidiaries, the Agent and the Banks have
entered into that certain Credit Agreement of even date herewith (as the same
may be amended, modified, supplemented or restated from time to time, the
"CREDIT AGREEMENT"), pursuant to which the Banks have agreed to extend to the
Company, upon the terms and subject to the conditions set forth therein, a

     WHEREAS, the Assignor is the owner of all right, title and interest in, to
and under the intellectual property rights as set forth on the attached Schedule
A.

     WHEREAS, the Agent and the Assignor have entered into a Security Agreement
of even date herewith (as such agreement may be amended from time to time
hereafter, the "Security Agreement"), pursuant to which the Assignor granted to
the Agent a security interest in certain Collateral (as defined in the Security
Agreement) of Assignor, including but not limited to Assignor's General
Intangibles (as defined in the Security Agreement) which include, but are not
limited to, the intellectual property set forth on Schedule A hereto, as
security for the payment or performance of Assignor's Secured Obligations (as
defined in the Security Agreement), and pursuant to which the Assignor therein
agreed to execute and cause to be filed all such further instruments and
documents as Agent may request for preserving the security interest.

     WHEREAS, the Agent has requested that the Assignor execute and deliver this
Instrument for the purpose of collaterally assigning its interests in, and
placing in the public record of the United States Patent and Trademark Office
the collateral assignment granted pursuant hereto to the Agent in, certain of
the Assignor's Collateral for the benefit of the Banks.
<PAGE>
 
     NOW, THEREFORE, in consideration of the foregoing premises, and intending
to be legally bound hereby, Assignor and Agent, on behalf of the Banks, hereby
agree as follows:

          1.   Definition of Terms Used Herein.  All capitalized terms not
               -------------------------------
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

          2.   Assignment and Security Interest.  As confirmation of the 
               -------------------------------- 
security interest granted by Assignor under the Security Agreement to secure the
complete and timely satisfaction of all Secured Obligations, Assignor hereby
ratifies the creation and grant of the security interest in, and further, to
secure the complete and timely satisfaction of all Secured Obligations, Assignor
does hereby hypothecate (subject to paragraph 6 hereof), as collateral security,
to the Agent: (i) the United States patent and patent applications owned by
Assignor, all reissue, divisional, continuation, or continuation-in-part patent
applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark
applications, trademarks (whether registered, unregistered or for which an
application to register has been filed), service mark applications, service
marks (whether registered, unregistered or for which an application to register
has been filed) and tradenames, together with the goodwill of the business
related thereto; including without limitation all renewals thereof and all
proceeds (such as license royalties or proceeds of infringement suits), and all
rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the 
               ----------------
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services. The time
and frequency of such inspections shall be consistent with those in Section 7.1
of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement
on any of the Patents, or shall obtain rights in any United States or foreign
trademark, service mark or tradename or any registrations or applications for
registration thereof, the provisions of paragraph 2 (except for the Schedule
which will contain only registered Patents and Marks) shall automatically apply
thereto and Assignor shall give to the Agent prompt notice thereof in writing.

          5.   Modification by Agent.  Assignor authorizes the Agent to modify
               ---------------------                                          
this Instrument by amending Schedule A to include all federally registered
Patents and Marks which hereafter fall within the scope of paragraph 2 or
paragraph 4 hereof.

          6.   Retention of Rights.  Unless and until there shall have occurred
               -------------------                                             
and be continuing an Event of Default, as defined in the Credit Agreement, the
Assignor shall retain the legal and equitable title to the Patents and the Marks
and shall have the right to use the Patents and the Marks in the ordinary course
of its business. Assignor agrees, except as provided in the Credit Agreement,
not to sell or assign its interest in, or grant any license under the Patents or
Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------                  
Default shall have occurred and be continuing under either the Credit Agreement
or the Security Agreement, the Agent shall have all those rights and remedies
given it under the Security Agreement and those allowed by law.

          8.   Release of Interest.  At such time as Assignor shall completely
               -------------------                                            
satisfy all of the Secured Obligations, Agent shall execute and deliver to
Assignor all deeds, assignments and other instruments as may be necessary or
proper to release its interests in and to the Patents and Marks subject to any
disposition thereof which may have been made by the Agent pursuant to the
Security Agreement or hereto.

          9.   Cumulative Rights; Confirmation of Rights and Obligations Under
               ---------------------------------------------------------------
Security Agreement.  All of the Agent's rights and remedies with respect to the
- ------------------                                                             
Patents and Marks, whether established hereby, the Security Agreement or by law
shall be cumulative and may be exercised singularly or concurrently. The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,
               -------------------------------                                  
covenants and conditions hereof, shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, except that
the Assignor shall not be permitted to assign this Instrument or any interest
herein or in the Collateral, or any part thereof, or otherwise pledge, encumber
or grant any option with respect to the Collateral, or any part thereof, or any
cash or property held by the Agent as Collateral under this Instrument, except
as contemplated by the Security Agreement or the Credit Agreement.

          11.  Governing Law.  This Instrument shall be construed in accordance
               -------------                                                   
with and governed by the laws of the Commonwealth of Pennsylvania, exclusive of
its rules on choice of law.

               SECURITY INTEREST IN INTELLECTUAL PROPERTY RIGHTS
                             

          THIS COLLATERAL ASSIGNMENT OF AND RATIFICATION OF SECURITY INTEREST IN
INTELLECTUAL PROPERTY RIGHTS (this "INSTRUMENT") is entered into this 23rd day
of December, 1996 by and between WHATCOM PHARMACEUTICAL SERVICES, INC., a

hereinafter defined), unless the context otherwise requires.

          WHEREAS, the Assignor, its subsidiaries, the Agent and the Banks have
entered into that certain Credit Agreement of even date herewith (as the same
may be amended, modified, supplemented or restated from time to time, the
"CREDIT AGREEMENT"), pursuant to which the Banks have agreed to extend to the

agreed to execute and cause to be filed all such further instruments and
documents as Agent may request for preserving the security interest.

          WHEREAS, the Agent has requested that the Assignor execute and deliver
this Instrument for the purpose of collaterally assigning its interests in, and
placing in the public record of the United States Patent and Trademark Office
the collateral assignment granted pursuant hereto to the Agent in, certain of

<PAGE>
 
          NOW, THEREFORE, in consideration of the foregoing premises, and
intending to be legally bound hereby, Assignor and Agent, on behalf of the
Banks, hereby agree as follows:
 
          1.   Definition of Terms Used Herein.  All capitalized terms not
               -------------------------------  
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

          2.   Assignment and Security Interest.  As confirmation of the
               --------------------------------                         
security interest granted by Assignor under the Security Agreement to secure the
complete and timely satisfaction of all Secured Obligations, Assignor hereby
ratifies the creation and grant of the security interest in, and further, to
secure the complete and timely satisfaction of all Secured Obligations, Assignor
does hereby hypothecate (subject to paragraph 6 hereof), as collateral security,
to the Agent: (i) the United States patent and patent applications owned by
Assignor, all reissue, divisional, continuation, or continuation-in-part patent
applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark
applications, trademarks (whether registered, unregistered or for which an
application to register has been filed), service mark applications, service
marks (whether registered, unregistered or for which an application to register
has been filed) and tradenames, together with the goodwill of the business
related thereto; including without limitation all renewals thereof and all
proceeds (such as license royalties or proceeds of infringement suits), and all
rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the
               ----------------                                            
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services. The time
and frequency of such inspections shall be consistent with those in Section 7.1
of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement
on any of the Patents, or shall obtain rights in any United States or foreign
trademark, service mark or tradename or any registrations or applications for
registration thereof, the provisions of paragraph 2 (except for the Schedule
which will contain only registered Patents and Marks) shall automatically apply
thereto and Assignor shall give to the Agent prompt notice thereof in writing.

               ---------------------                                          
this Instrument by amending Schedule A to include all federally registered
Patents and Marks which hereafter fall within the scope of paragraph 2 or
paragraph 4 hereof.

          6.   Retention of Rights.  Unless and until there shall have occurred
               -------------------                                             
and be continuing an Event of Default, as defined in the Credit Agreement, the
Assignor shall retain the legal and equitable title to the Patents and the Marks
and shall have the right to use the Patents and the Marks in the ordinary course
of its business.  Assignor agrees, except as provided in the Credit Agreement,
not to sell or assign its interest in, or grant any license under the Patents or
Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------                  
Default shall have occurred and be continuing under either the Credit Agreement
or the Security Agreement, the Agent shall have all those rights and remedies
given it under the Security Agreement and those allowed by law.

          8.   Release of Interest.  At such time as Assignor shall completely
               -------------------                                            
satisfy all of the Secured Obligations, Agent shall execute and deliver to
Assignor all deeds, assignments and other instruments as may be necessary or
proper to release its interests in and to the Patents and Marks subject to any
disposition thereof which may have been made by the Agent pursuant to the
Security Agreement or hereto.

          9.   Cumulative Rights; Confirmation of Rights and Obligations Under
               ---------------------------------------------------------------
Security Agreement.  All of the Agent's rights and remedies with respect to the
- ------------------                                                             
Patents and Marks, whether established hereby, the Security Agreement or by law
shall be cumulative and may be exercised singularly or concurrently.  The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,
               -------------------------------                                  
covenants and conditions hereof, shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, except that
the Assignor shall not be permitted to assign this Instrument or any interest
herein or in the Collateral, or any part thereof, or otherwise pledge, encumber
or grant any option with respect to the Collateral, or any part thereof, or any
cash or property held by the Agent as Collateral under this Instrument, except
as contemplated by the Security Agreement or the Credit Agreement.

          11.  Governing Law.  This Instrument shall be construed in accordance
               -------------                                                   
with and governed by the laws of the Commonwealth of Pennsylvania, exclusive of
its rules on choice of law.

<PAGE>
 
     NOW, THEREFORE, in consideration of the foregoing premises, and intending
to be legally bound hereby, Assignor and Agent, on behalf of the Banks, hereby
agree as follows:

          1.   Definition of Terms Used Herein. All capitalized terms not
               -------------------------------
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

          2.   Assignment and Security Interest.  As confirmation of the 
               --------------------------------
security interest granted by Assignor under the Security Agreement to secure the
complete and timely satisfaction of all Secured Obligations, Assignor hereby
ratifies the creation and grant of the security interest in, and further, to

does hereby hypothecate (subject to paragraph 6 hereof), as collateral security,
to the Agent: (i) the United States patent and patent applications owned by
Assignor, all reissue, divisional, continuation, or continuation-in-part patent
applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark
applications, trademarks (whether registered, unregistered or for which an
application to register has been filed), service mark applications, service
marks (whether registered, unregistered or for which an application to register
has been filed) and tradenames, together with the goodwill of the business
related thereto; including without limitation all renewals thereof and all
proceeds (such as license royalties or proceeds of infringement suits), and all
rights to sue for past, present and future infringements (collectively called
the "Marks"). All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the 
               ----------------
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services. The time
and frequency of such inspections shall be consistent with those in Section 7.1
of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement
on any of the Patents, or shall obtain rights in any United States or foreign
trademark, service mark or tradename or any registrations or applications for
registration thereof, the provisions of paragraph 2 (except for the Schedule
which will contain only registered Patents and Marks) shall automatically apply
thereto and Assignor shall give to the Agent prompt notice thereof in writing.

this Instrument by amending Schedule A to include all federally registered
Patents and Marks which hereafter fall within the scope of paragraph 2 or

and be continuing an Event of Default, as defined in the Credit Agreement, the
Assignor shall retain the legal and equitable title to the Patents and the Marks
and shall have the right to use the Patents and the Marks in the ordinary course
of its business. Assignor agrees, except as provided in the Credit Agreement,
not to sell or assign its interest in, or grant any license under the Patents or
Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------                  
Default shall have occurred and be continuing under either the Credit Agreement
or the Security Agreement, the Agent shall have all those rights and remedies
given it under the Security Agreement and those allowed by law.

          8.   Release of Interest.  At such time as Assignor shall completely
               -------------------                                            
satisfy all of the Secured Obligations, Agent shall execute and deliver to
Assignor all deeds, assignments and other instruments as may be necessary or
proper to release its interests in and to the Patents and Marks subject to any
disposition thereof which may have been made by the Agent pursuant to the
Security Agreement or hereto.

          9.   Cumulative Rights; Confirmation of Rights and Obligations Under
               ---------------------------------------------------------------
Security Agreement.  All of the Agent's rights and remedies with respect to the
- ------------------                                                             
Patents and Marks, whether established hereby, the Security Agreement or by law
shall be cumulative and may be exercised singularly or concurrently. The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,
               -------------------------------                                  
covenants and conditions hereof, shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, except that
the Assignor shall not be permitted to assign this Instrument or any interest
herein or in the Collateral, or any part thereof, or otherwise pledge, encumber
or grant any option with respect to the Collateral, or any part thereof, or any
cash or property held by the Agent as Collateral under this Instrument, except
as contemplated by the Security Agreement or the Credit Agreement.

          11.  Governing Law.  This Instrument shall be construed in accordance

               SECURITY INTEREST IN INTELLECTUAL PROPERTY RIGHTS


     THIS COLLATERAL ASSIGNMENT OF AND RATIFICATION OF SECURITY INTEREST IN
INTELLECTUAL PROPERTY RIGHTS (this "INSTRUMENT") is entered into this 23rd day
of December, 1996 by and between OPTION CARE HOME HEALTH, INC., an Ohio

shall have the meanings ascribed to such terms in the Credit Agreement (as
hereinafter defined), unless the context otherwise requires.

     WHEREAS, the Assignor, its subsidiaries, the Agent and the Banks have

may be amended, modified, supplemented or restated from time to time, the
"CREDIT AGREEMENT"), pursuant to which the Banks have agreed to extend to the

documents as Agent may request for preserving the security interest.

     WHEREAS, the Agent has requested that the Assignor execute and deliver this
Instrument for the purpose of collaterally assigning its interests in, and
placing in the public record of the United States Patent and Trademark Office
the collateral assignment granted pursuant hereto to the Agent in, certain of

<PAGE>
 
     NOW, THEREFORE, in consideration of the foregoing premises, and intending
to be legally bound hereby, Assignor and Agent, on behalf of the Banks, hereby
agree as follows:
 
          1.   Definition of Terms Used Herein.  All capitalized terms not
               -------------------------------                            
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

          2.   Assignment and Security Interest.  As confirmation of the
               --------------------------------                         
security interest granted by Assignor under the Security Agreement to secure the
complete and timely satisfaction of all Secured Obligations, Assignor hereby

Assignor, all reissue, divisional, continuation, or continuation-in-part patent
applications and patents related thereto, and all renewals and extensions
thereof and reexamination certificates relating thereto; including, without
limitation, all proceeds (such as license royalties or proceeds of infringements
suits), and all rights to sue for past, present, and future infringements
(collectively called the "Patents"); and (ii) all of Assignor's trademark
applications, trademarks (whether registered, unregistered or for which an
application to register has been filed), service mark applications, service
marks (whether registered, unregistered or for which an application to register
has been filed) and tradenames, together with the goodwill of the business
related thereto; including without limitation all renewals thereof and all
proceeds (such as license royalties or proceeds of infringement suits), and all
rights to sue for past, present and future infringements (collectively called
the "Marks").  All registered Patents and Marks are and shall be listed on
Schedule A.

          3.   Right to Inspect.  Assignor hereby confirms the right of the
               ----------------                                            
Agent and its employees and agents to visit Assignor's plants and facilities
where products sold or services provided under any of the Marks are
manufactured, inspected, stored, or provided, and to inspect and review the
products and quality control records relating thereto at reasonable times.
Assignor confirms its commitment to do any and all acts required by the Agent to
ensure maintenance of quality standards for such products and services.  The
time and frequency of such inspections shall be consistent with those in Section
7.1 of the Credit Agreement.

          4.   Future Intellectual Property.  If, before the Secured Obligations
               ----------------------------                                     
shall have been satisfied in full, Assignor shall either obtain rights to any
invention or become entitled to any rights under or the benefit of any United
States or foreign patent application or patent, including any reissue,
divisional, continuation, or continuation-in-part patent applications or
reexamination certificates related to any of the Patents or to any improvement
on any of the Patents, or shall obtain rights in any United States or foreign
trademark, service mark or tradename or any registrations or applications for
registration thereof, the provisions of paragraph 2 (except for the Schedule
which will contain only registered Patents and Marks) shall automatically apply
thereto and Assignor shall give to the Agent prompt notice thereof in writing.

               ---------------------                                          
this Instrument by amending Schedule A to include all federally registered
Patents and Marks which hereafter fall within the scope of paragraph 2 or
paragraph 4 hereof.

          6.   Retention of Rights.  Unless and until there shall have occurred
               -------------------                                             
and be continuing an Event of Default, as defined in the Credit Agreement, the
Assignor shall retain the legal and equitable title to the Patents and the Marks
and shall have the right to use the Patents and the Marks in the ordinary course
of its business.  Assignor agrees, except as provided in the Credit Agreement,
not to sell or assign its interest in, or grant any license under the Patents or
Marks without the prior written consent of the Agent; provided, however that
nothing herein contained shall prohibit the Assignor from failing to continue
the prosecution of, maintain, renew or otherwise abandoning any item included in
the Marks or the Patents, if in the Assignor's reasonable judgment, the
retention of such items is not material to the proper conduct of Assignor's
business.

          7.   Agents Rights and Obligations As Secured Party.  If any Event of
               ----------------------------------------------                  
Default shall have occurred and be continuing under either the Credit Agreement
or the Security Agreement, the Agent shall have all those rights and remedies
given it under the Security Agreement and those allowed by law.

          8.   Release of Interest.  At such time as Assignor shall completely
               -------------------                                            
satisfy all of the Secured Obligations, Agent shall execute and deliver to
Assignor all deeds, assignments and other instruments as may be necessary or
proper to release its interests in and to the Patents and Marks subject to any
disposition thereof which may have been made by the Agent pursuant to the
Security Agreement or hereto.

          9.   Cumulative Rights; Confirmation of Rights and Obligations Under
               ---------------------------------------------------------------
Security Agreement.  All of the Agent's rights and remedies with respect to the
- ------------------                                                             
Patents and Marks, whether established hereby, the Security Agreement or by law
shall be cumulative and may be exercised singularly or concurrently.  The
Assignor hereby ratifies and confirms all of its obligations contained in the
Security Agreement and confirms in the Agent for the benefit of the Banks all of
the rights granted to the Agent thereunder by the Assignor.

          10.  Binding Instrument; Assignments.  This Instrument, and the terms,
               -------------------------------                                  
covenants and conditions hereof, shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns, except that
the Assignor shall not be permitted to assign this Instrument or any interest
herein or in the Collateral, or any part thereof, or otherwise pledge, encumber
or grant any option with respect to the Collateral, or any part thereof, or any
cash or property held by the Agent as Collateral under this Instrument, except
as contemplated by the Security Agreement or the Credit Agreement.

          11.  Governing Law.  This Instrument shall be construed in accordance
               -------------

                               OPTION CARE, INC.
                              FRANCHISE AGREEMENT


     This Franchise Agreement ("Agreement") between Option Care, Inc., a
California corporation, with its principal place of business at Bannockburn,
Illinois ("Franchisor") and Option Care Camilla, Inc., a Georgia corporation,
("Franchise Owner"), is made and entered into effective the date signed by
Franchisor on the signature page hereof (the "Effective Date").

                                   RECITALS

    A.   Franchisor has developed and owns a proprietary business method and
concept (the "System") relating to the operation of an outpatient health care
business that compounds pharmaceuticals, dispenses and administers
pharmaceuticals and physician prescribed biologicals, nutrients, medications and
solutions via parenteral and enteral routes in the home and in, subacute,
extended care, and other outpatient settings, furnishes clinical, pharmaceutical
and nursing services necessary to the provision of such therapies, sells related
products and supplies and sells or leases related equipment.  For purposes of
this Agreement, "parenteral" shall mean any administration route other than by
way of the intestines (e.g., without limitation, inhalation, transdermal and
intravenous).

    B.   The therapies under the System (the "Therapies") are set forth in the
Confidential Franchise Operations Manual (the "Manual") and include "Core
Therapies" and "Permitted Therapies", both as defined in the Manual.

    C.   The distinguishing characteristics of the System are set forth in the
Manual, which contains, without limitation, policies and procedures for the
Therapies; uniform standards, specifications and procedures for operation of the
business under the System, including the nature and manner of products and
services offered; procedures for quality improvement; training requirements;
group purchasing availability; and management, operational, and marketing
methods, techniques, materials, assistance and programs.

    D.   Pursuant to a license from Franchisor, each of Franchisor's franchise
owners does business under the name and mark "Option Care," and such other names
and marks as Franchisor may designate for use by each franchise owner under the
System (collectively, the "Proprietary Marks").

    E.   Franchise Owner wishes to obtain a franchise in order to operate a
business utilizing the System and the Proprietary Marks, as well as to receive
the Manual, the training and other assistance provided by Franchisor in
connection with the System pursuant to this Agreement.

                                       6
<PAGE>
 
    F.   The business to be conducted by Franchise Owner pursuant to and under
the license granted by this Agreement is sometimes referred to herein as the
"Franchised Business".

    G.   Franchise Owner understands and acknowledges the importance of
Franchisor's high and uniform standards of quality and service and the necessity
of operating the Franchised Business in conformity with Franchisor's standards
and specifications, including the Manual.

    H.   Franchise Owner acknowledges that it has received a copy of this
Agreement, and the related exhibits and agreements, at least five (5) business
days prior to the date on which this Agreement was executed by Franchise Owner.
Franchise Owner further acknowledges that it has received the disclosure
document required by the Trade Regulation Rule of the Federal Trade Commission,
entitled "Offering Circular for Prospective Franchise Owners," at least ten (10)
business days prior to the date on which this Agreement was executed.

    NOW, THEREFORE, Franchisor and Franchise Owner, in consideration of the
undertakings and commitments of each party to the other party set forth herein
and the recitals set forth above, which are  incorporated into and made a part
of this Agreement, mutually agree as follows:

 1. GRANT

    1.1  Grant of Franchise.  Franchisor hereby grants to Franchise Owner, on
         -------------------                                                 
the terms and conditions contained in this Agreement, the right and franchise,
and Franchise Owner undertakes the obligation, to operate the Franchised
Business and to use solely in connection with the Franchised Business the System
and the Proprietary Marks.

    1.2  Deliveries on Grant.  Contemporaneous with Franchise Owner delivering
         -------------------                                                  
this executed Agreement to Franchisor, it shall also deliver to Franchisor the
following:

         (a) A check in the amount specified in Section 5.1 hereof;

         (b) A copy of the fronts and backs of its issued stock certificates,
the backs of which shall contain the following legend:  "The transfer of this
stock is subject to the terms and conditions of a Franchise Agreement with
Option Care, Inc. dated _____________________, 1996";

         (c) An executed "Site Selection Addendum; and

         (d) A fully executed "Guarantee".

                                       7
<PAGE>
 
2.   TERRITORY

    2.1  Territory Defined.  Franchisor hereby grants to Franchise Owner the
         -----------------                                                  
right to operate the Franchised Business during the term of this Agreement
within the defined area (the "Territory") described on attached Exhibit A, which
Exhibit is incorporated herein by reference thereto.  Franchise Owner
acknowledges and agrees that this Agreement affords it no right, title or
interest in or to additional franchises or any right to acquire additional
franchises or territory, nor does it obligate Franchisor in any way to grant or
sell any additional franchises or territory to Franchise Owner.

    2.2  Patient Freedom of Choice.  Notwithstanding the grant of the Territory,
         -------------------------                                              
Franchise Owner acknowledges and agrees that (i) patients residing within the
Territory are entitled to the freedom to choose their health care provider and
may seek health care services of the type provided by Franchise Owner from
others, including another franchise owner of Franchisor; and (ii) health care
referral sources may refer patients residing within the Territory to health care
providers of their choosing, including to another franchise owner of Franchisor.

    2.3  Marketing Efforts in Territory.  Franchise Owner agrees to devote its
         ------------------------------                                       
best efforts to serving patients that reside within the Territory.  Except as
otherwise permitted herein or as approved in advance and in writing by
Franchisor, Franchise Owner's marketing and promotional activities shall be
directed only toward obtaining patients who reside within the Territory.
Franchise Owner acknowledges and agrees that Franchisor, as part of its business
strategy, may advertise or market on behalf of the System in the Territory and
may maintain itself, or through its affiliates, a presence in the Territory for
the purpose of providing a managed care program offering services of the type
provided by the Franchised Business. Franchise Owner agrees to abide by
Franchisor's then current policies on marketing outside of the Territory, and on
cooperating with neighboring Option Care franchisees, as the same may be set
forth from time to time in the Manual.

    2.4  Presence in Territory.  Franchise Owner shall maintain such manner and
         ---------------------                                                 
degree of presence in the Territory as from time to time required by the Manual.
Such presence requires Franchise Owner to maintain an I.V. pharmacy within the
Territory unless Franchise Owner has the prior written approval of Franchisor to
utilize the I.V. pharmacy services of another Option Care Franchise and utilize
such services on the basis approved by Franchisor. Even if Franchise Owner is
not required to itself maintain an I.V. pharmacy in the Territory, it must
maintain a physical presence in the Territory consistent with Franchisor's
requirements therefor as then set forth in the current Manual. The initial
pharmacy and/or office site must be selected by Franchise Owner and disclosed to
Franchisor at the time of filing the application for a franchise, but not later
than sixty (60) days after execution of the Franchise Agreement. A location
shall be selected by Franchise Owner in accordance with the then-current Site
Selection Addendum.  The Franchise Owner's presence within the Territory shall
at all times comply with Franchisor's reasonable standards and conditions and
any relocations of a physical pharmacy or office or change in the manner or
degree of presence must be approved in advance in writing by Franchisor.
Franchise Owner shall not relocate any part of 

                                       8
<PAGE>
 
the Franchised Business without the prior written consent of Franchisor.
Franchise Owner agrees that disapproval of a location will not be unreasonable
if the proposed location does not meet Franchisor's reasonable standards,
including spacing between franchised offices.

    2.5  Servicing Unowned Territory.  Franchise Owner acknowledges that while
         ---------------------------                                          
it is granted the right hereunder only to the Territory, Franchise Owner may
provide goods and services to patients in unowned areas until such time as those
areas are granted by Franchisor to a party.  Franchise Owner acknowledges and
agrees that it is obligated to pay royalties to Franchisor, in accordance with
Section 5 hereof, on all Gross Receipts (as hereafter defined), whether from
patients residing within or outside the Territory.  Franchise Owner further
acknowledges and agrees that neither the ability to service nor the grant of our
permission to service patients residing outside the Territory affords it any
right, title or interest in or to such area whatsoever (including any right to
acquire such area or any right of first refusal as to such area).
 
 3. TERM ; RENEWAL; CONSEQUENCES OF EXPIRATION (NON-RENEWAL)

    3.1  Term.  Unless sooner terminated as hereinafter provided, this Agreement
         ----                                                                   
shall expire twenty (20) years from the Effective Date of this Agreement.  If
this Agreement reaches the end of its term and is not renewed, it will be said

below, shall apply.

    3.2  Renewal.  If Franchise Owner, in Franchisor's sole interpretation,
         -------                                                           
meets all of the requirements described in this Section 3.2, then Franchise
Owner shall have the right to extend the right to operate the Franchised
Business for one (1) consecutive additional period of ten (10) years.  To
exercise the right to extend, Franchise Owner shall send to Franchisor, at least
one six (6) months, but not more than twelve (12) months, prior to the
expiration date of this Agreement  a written notice of intention to extend.  At
the time of the notice and at the time of the execution of the renewal franchise
agreement, Franchise Owner must satisfy the following conditions:

this Agreement and shall have substantially complied with all the terms and
conditions of  this Agreement, as amended, throughout its term;

         3.2.2   Franchise Owner shall have satisfied all of its monetary
obligations to Franchisor and Franchisor's affiliates and shall have met those
obligations in a timely manner throughout the term of  this Agreement;

         3.2.3   Franchise Owner shall execute Franchisor's then-current form of
renewal franchise agreement for the renewal term, which franchise agreement may
have terms different from the terms of this Agreement, and such other ancillary
agreements as Franchisor may require for the Franchised Business.  The Territory
described in this Agreement shall remain the same;

<PAGE>
 
         3.2.4   Franchise Owner shall pay, in lieu of an initial fee, a renewal
fee  not to exceed the conversion fee that would then be charged a conversion
candidate for this Territory;

         3.2.5   Franchise Owner shall execute a general release, in a form
prescribed by Franchisor, of any and all claims against Franchisor and
Franchisor's affiliates, and their respective shareholders, partners, directors,
officers, employees and agents, in this capacity and in their individual
capacities, to the fullest extent permitted by law; and

         3.2.6   Franchise Owner shall comply with Franchisor's then-current
qualification and training requirements.

    3.3  Consequences of Expiration.  If either Franchise Owner or Franchisor
         --------------------------                                          
elects not to renew this Agreement, then, upon expiration of its term, all
rights granted Franchisor Owner by this Agreement shall terminate, and Franchise
Owner shall immediately:

not refundable under any circumstances.

    5.2  Continuing Royalty.  In addition to the initial fee, during the initial
         ------------------

Gross Receipts (as defined in Section 5.7), Franchise Owner agrees to pay to
Franchisor a continuing monthly royalty fee (the "Continuing Monthly Royalty
Fee") in the amount equal to nine percent (9%) of the first $1,000,000 of Gross
Receipts during each calendar year, seven percent (7%) of the next $1,000,000 of
Gross Receipts during each calendar year, and five percent (5%) of all Gross
Receipts in excess of $2,000,000 during each calendar year.  The dollar amounts
subject to the 9%, 7% and 5% royalty percentage rates ("Dollar Amounts") shall

Dollar Amounts shall be multiplied by a fraction (the "Fraction") determined as

Dollar Amounts.  All royalty payments due Franchisor during the calendar year of
the adjustment shall be calculated based on the replacement Dollar Amounts.  If
the index is changed such that the base year differs for the two months used in

Royalty  Fees owed for that  period.  The Minimum  Royalty Fee is the following

comply with the requirements of this Section 9 will cause Franchisor irreparable
injury, and Franchise Owner agrees to pay all court costs and reasonable
attorneys' fees incurred by Franchisor in obtaining specific performance of, or
an injunction against violation of, the requirements of this Section 9.

10. MARKETING AND PROMOTION; NATIONAL FUND

    Recognizing the value of marketing and promotion and the importance of the
standardization of marketing programs to the furtherance of the System, the
parties agree as follows:

    10.1 Comply with Marketing Policies.  Franchise Owner agrees to comply with
         ------------------------------                                        
all reasonable marketing and promotion policies and procedures prescribed by
Franchisor.  Such policies and procedures may include opening and ongoing
marketing and promotional campaigns; a direct mail campaign directed to a list
representative of Franchise Owner's local referral sources; and advertising
programs or campaigns in which Franchise Owner's participation shall be deemed
necessary by Franchisor.

    10.2 Submit Marketing Plans.  Franchise Owner agrees to submit to
         ----------------------                                      
Franchisor, through the mail, return receipt requested, for its prior approval
(except with respect to prices to be charged), samples of all marketing and
promotional plans and materials that Franchise Owner desires to use and which
have not been prepared or previously approved by Franchisor within the prior
twelve month period.  If written disapproval thereof is not received by
Franchise Owner from Franchisor within fifteen (15) days of receipt by
Franchisor of such samples or materials, Franchisor shall be deemed to have
given the required approval. Franchisor reserves the right to communicate, in
whole or in part, marketing and promotional plans and materials which it
receives from the Franchise Owner to other franchise owners for their use, or to
use the same in any marketing and promotion by Franchisor.

    10.3 National Fund. Franchise Owner's monthly contribution to the National
         -------------                                                        
Fund may be increased to exceed one and one-half percent (1.5%) of Gross
Receipts, and/or the maximum annual contribution may exceed $10,000, if two-
thirds (2/3) of all franchise owners who are obligated to contribute to the
National Fund vote for an increase in the contribution to the National Fund.  In
connection with any vote to increase contributions to the National Fund,
Franchise Owner shall have one vote for each franchise agreement under which
Franchise Owner is required to become a member of the National Fund.  The
National Fund shall be maintained and administered by Franchisor or its
designee, as follows:

         10.3.1  The National Fund, all contributions thereto, and any earnings
thereon shall be used exclusively to meet any and all costs of preparing,
offering, distributing, obtaining, conducting and administering marketing, and
educational  activities, and providing training opportunities for Option Care
franchisees;

                                       22
<PAGE>
 
         10.3.2  Franchisor shall direct all activities of the National Fund
with sole discretion over the concepts, materials, and media used and the
placement and allocation thereof.  Franchise Owner agrees and acknowledges that
Franchisor undertakes no obligation in administering the National Fund to make
expenditures for Franchise Owner which are equivalent or proportionate to
Franchise Owner's contribution or to insure that any particular franchise owner
benefits directly or pro rata from expenditures by the National Fund;

         10.3.3  Franchise Owner agrees to contribute to the National Fund by
separate check made payable to the National Fund.  All sums paid by Franchise
Owner to the National Fund shall be maintained in an account separate from the
other monies of Franchisor and shall not be used to defray any of Franchisor's
expenses, except for such reasonable administrative costs and overhead, if any,
as Franchisor may incur in activities reasonably related to the conduct of
activities under and maintenance and administration of the National Fund.  The
National Fund and its earnings shall not otherwise inure to the benefit of
Franchisor. Franchisor shall maintain separate bookkeeping accounts for the
National Fund, which shall not be an asset of Franchisor.  A statement of the
operations of the National Fund as shown on the books of the National Fund shall
be prepared annually and shall be made available to Franchise Owner;

         10.3.4  It is intended that contributions to, and earnings of, the
National Fund shall not be taxable income to Franchisor.  Toward this end, it is
anticipated that all contributions to and earnings of the National Fund will be
expended for marketing, educational training and promotional purposes during the
taxable year of receipt.  If, however, excess amounts remain in the National
Fund at the end of a taxable year, all expenditures in the following taxable
year(s) shall be made first out of accumulated earnings from previous years,
next out of earnings in the current year and finally from contributions; and

         10.3.5  Although the National Fund is intended to be of perpetual
duration, Franchisor maintains the right to terminate the National Fund.  The
National Fund shall not be terminated, however, until all monies in the National
Fund have been expended in accordance with the provisions of this Section  5.4
or returned to contributors on the basis of their respective contributions.

11. ACCOUNTING AND RECORDS

    11.1 Preserve Records.  Franchise Owner shall preserve, for at least five

Business during the fiscal year.

    11.3 Provide Other Business Records.  Franchise Owner shall also submit to
         ------------------------------                                       
Franchisor, for review or auditing, such other forms, reports, records,
information and data as Franchisor may reasonably designate, including but not
limited to income tax returns, in the form and manner, and at the times and
places, as are reasonably specified by Franchisor.

    11.4 Right to Inspect Business Records.  Franchisor or its designated agents
         ---------------------------------                                      
shall have the right at all reasonable times to inspect, audit and copy, at
Franchisor's expense, without notice, Franchise Owner's books, business tax
returns and other business records for the Franchised Business.  Franchisor
shall also have the right, at any time, to have an independent audit made of the
books and records of the Franchised Business.  If an inspection or audit should
reveal that any Gross Receipts have been understated in any report to
Franchisor, then Franchise Owner shall immediately pay to Franchisor, upon
demand, all royalties due on the amount understated, in addition to interest
from the date such royalties were due until paid, at the rate which is two
percent (2%) per month or the maximum rate permitted by law, whichever is less.
If an inspection or audit discloses an understatement of five percent (5%) or
more in any report of Gross Receipts, Franchise Owner shall, in addition,
reimburse Franchisor for any and all costs and expenses connected with the
inspection or audit (including, without limitation, travel, lodging and wage
expenses and reasonable accounting and legal costs).  The foregoing remedies
shall be in addition to any other remedies Franchisor may have.

the required policy or policies in the amounts specified shall not be limited in
any way by reason of any insurance which may be maintained by Franchisor, nor
shall Franchise Owner's performance of that obligation relieve it of liability
under the indemnity provisions set forth in Section 20 of this Agreement.

their respective shareholders, partners, directors, officers, employees and
agents, in their corporate and individual capacities, to the fullest extent
permitted by law;

                 13.1.2.5  Each Transferee shall enter into a written assignment
in a form satisfactory to Franchisor, assuming and agreeing to discharge all of
Franchise Owner's obligations under this Agreement;

                 13.1.2.6  Each Transferee shall demonstrate to Franchisor's
satisfaction that such Transferee meets Franchisor's professional, educational,
managerial, financial and business standards, and possesses a good moral
character;

                 13.1.2.7  Any person who is to be substituted as Manager of the
Franchised Business shall have been approved by Franchisor and, unless waived in
writing by Franchisor, shall successfully complete the next available franchise
training and complete the Install Program training course then in effect;

                 13.1.2.8  Transferor shall pay to Franchisor a non-refundable
transfer fee to cover Franchisor's legal, accounting, record keeping and other
costs related to the Transfer in an amount not to exceed fifty percent (50%) of
the initial fee that then would be charged to new franchise owners under the
System for a comparable territory;

                 13.1.2.9  Transferor shall agree to remain liable for all of

Transferor shall be the owner of all the voting stock of the corporation; and

                 13.1.2.11 In the event a Transfer, alone or together with other
Transfers, would have the effect of transferring a controlling interest in the
Franchise, the Transferee shall execute, for a term ending on the expiration
date of this Agreement, the standard form of franchise agreement then offered to
new franchise owners, which franchise agreement may have terms different from
the terms of this Agreement; provided, however, in lieu of any initial fee, the
Transferor shall pay the transfer fee described in Section 13.1.2.8 above, and
the royalty fee, the National Fund contribution limitation, and the Territory
shall remain the same.  The Transferee shall also execute such other ancillary
agreements as Franchisor may require for the Franchised Business.

    13.2 Offerings by Franchise Owner.  Securities or partnership interests in
         ----------------------------                                         
Franchise Owner may be sold, by public or private offering or otherwise, only
with the prior written consent of Franchisor (whether or not Franchisor's
consent is required under Section 13.1 hereof), which consent shall not be
unreasonably withheld.  All materials required for such offering by federal or
state law shall be 

                                       27
<PAGE>
 
submitted to Franchisor for review prior to being filed with any government
agency; and any materials to be used in any exempt offering shall be submitted
to Franchisor for review prior to their use. Franchise Owner shall provide all
such materials to Franchisor at least thirty (30) days prior to the commencement
of any offering. No Franchise Owner offering shall imply (by use of the
Proprietary Marks or otherwise) that Franchisor is participating as an
underwriter, issuer or offeror of securities; and Franchisor's review of any
offering shall be limited solely to the subject of the relationship between
Franchise Owner and Franchisor. Franchise Owner and the other participants in
the offering must fully indemnify Franchisor in connection with the offering.
For each proposed offering, Franchise Owner shall pay to Franchisor a non-
refundable fee, not to exceed fifty percent (50%) of the initial fee that then
would be charged to new franchise owners under the System for a comparable
territory, to reimburse Franchisor for its reasonable costs and expenses
associated with reviewing the proposed offering.

    13.3 Right of First Refusal.
         ---------------------- 

         13.3.1  Any party holding any interest in the Franchise who desires to
accept any offer from a third party to purchase such interest shall notify
Franchisor in writing of the offer, and shall provide such information and
documentation relating to the offer as Franchisor may require.

         13.3.2  Except for a Transfer among the original owners who were
granted the franchise hereunder or a Transfer from an original owner to that
owner's spouse or child(ren), Franchisor shall have the right and option,
exercisable within sixty (60) days after receipt of written notification and
receipt of any required information or documentation, to send written notice to
the seller that Franchisor intends to purchase the seller's interest on the same
terms and conditions contained in a bona fide offer from the third party, or the
                                    ---- ----                                   
cash equivalent.  In the event that Franchisor elects to purchase the seller's
interest, closing on such purchase must occur within sixty (60) days from the
date of notice to the seller of the election to purchase by Franchisor.  In the
event that Franchisor does not elect to purchase the sellers' interest, closing
on such purchase shall occur within ninety (90) days after the expiration of
Franchisor's right to purchase.  Failure to close the sale within said period or
any material change in the terms of the offer prior to closing shall constitute
a new offer subject to the same rights of first refusal by Franchisor described
in this Section 13.3.

         13.3.3  Failure of Franchisor to exercise the option afforded by this
Section 13.3 shall not constitute a waiver of any other provision of this
Agreement, including all the requirements of this Section 13, with respect to a
proposed Transfer.

    13.4  Transfer Upon Death or Mental Incapacity.  Upon the death or finding
          ----------------------------------------                            
by a court of mental incapacity of any person with an interest in the Franchise,
the executor, administrator or personal representative of such person shall
transfer within six (6) months after such death or mental incapacity the
deceased or incompetent owner's interest to a third party approved by
Franchisor.  Such transfers, including transfers by devise or inheritance, shall
be subject to the same conditions as any Transfer.  However, in the case of
transfer by devise or inheritance, if the heirs or beneficiaries of any such
person are not approved by Franchisor, the personal representative of the
deceased shall have a reasonable time to dispose 

                                       28
<PAGE>
 
of the deceased's interest, which disposition shall be subject to all the terms
and conditions for Transfers contained in this Agreement. If the interest is not
disposed of within six (6) months, Franchisor may terminate this Agreement.

    13.5  Non-Waiver of Claims.  Franchisor's consent to a Transfer shall not
          --------------------                                               
constitute a waiver of any claims it may have against the Transferor, nor shall
it be deemed a waiver of Franchisor's right to demand exact compliance with any
of the terms of this Agreement by the Transferee.

    13.6  Transfer by Franchisor.  Franchisor shall have the right to transfer
          ----------------------                                              
or assign all or any part of its rights or obligations herein to any person or
legal entity.

forfeits the right to transact business in the Territory.  However, if such
abandonment results from the governmental exercise of the power of eminent

following notice pursuant to Section 14.3, commits the same default, whether or
not cured after notice;

Section 16 or fails to obtain execution of the covenants required under Section

connection with the application to Franchisor for this Franchise Agreement;

in default under this Agreement, and this Agreement shall automatically
terminate without notice to Franchise Owner:

                                       30
<PAGE>
 
         14.2.1  Franchise Owner becomes insolvent, makes an assignment for the

as provided in Section 14.1 and 14.2 of this Agreement, Franchisor may terminate
this Agreement only by giving written notice of termination to Franchise Owner
stating the nature of the default or breach at least thirty (30) days prior to
the effective date of termination or such longer period as applicable law may
require (the "Cure Period"); provided, however, that Franchise Owner may avoid
termination by immediately initiating a remedy to cure such default or breach

16. COVENANTS

    16.1 Confidentiality Covenant.  Franchise Owner and, if Franchise Owner is a
         ------------------------                                               
corporation, partnership or limited liability company, its shareholders,
partners or owners, as the case may be (collectively, the "Owners"), each
specifically acknowledge that Franchise Owner and its Owners will receive
valuable specialized training and Confidential Information by entering into this
Agreement.  Franchise Owner and each of its Owners covenant that during the term
of this Agreement, except as otherwise approved in advance and in writing by
Franchisor, neither Franchise Owner nor any of its Owners shall, either directly
or indirectly, for itself, or through, on behalf of, or in conjunction with any
person, persons or legal entity, own, maintain, operate, engage in, be employed
by or have any interest in any business which provides health-care services
similar to, or the same as, those provided by Franchise Owner pursuant to this
Agreement.

    16.2 Non-Competition Restriction.  Franchise Owner and each of its Owners
         ---------------------------                                         
covenant that, except as otherwise approved in advance and in writing by
Franchisor, neither Franchise Owner nor any of its Owners shall, for a
continuous uninterrupted period commencing upon the termination (but not the
expiration) of this Agreement (or if the termination of this Agreement is
contested by Franchise Owner or an Owner, upon the final resolution of any
dispute concerning the termination of this Agreement) regardless of the cause
for termination and continuing for two (2) years thereafter, either directly or
indirectly, for itself, or through, on behalf of, or in conjunction with any
person, persons or legal entity:

         16.2.1  Own, maintain, operate, engage in, be employed by or have any
interest in any business which provides within the Territory health-care
services similar to, or the same as, those Franchise Owner could provide
pursuant to this Agreement;

         16.2.2  Seek or accept referrals for the provision of health-care
services similar to, or the same as, those provided by Franchise Owner pursuant
to this Agreement from any referral source which referred patients to Franchise
Owner for goods or services of the Franchised Business at any time during the
two (2) years prior to the termination of this Agreement; or

         16.2.3  Provide health-care services similar to, or the same as, those
provided by Franchise Owner pursuant to this Agreement to any patient to whom
Franchise Owner provided any health-care services under this Agreement at any
time during the two (2) years 

                                       33
<PAGE>
 
prior to the termination of this Agreement, provided, however, that Franchise
Owner shall be obligated to provide all current patients with notice to seek
alternate arrangements and shall assume that arrangements have been made for the
provision of such services.

    16.3 Exceptions from Non-Competition Restrictions. Notwithstanding the
         --------------------------------------------                     
foregoing, Section 16.2 shall not prohibit an Owner who is a licensed pharmacist
or nurse from:  (a) engaging in activities which are unrelated to Therapies
provided under the System; (b) having an interest in any business (e.g., a
retail pharmacy, home health agency or durable medical equipment business) which
does not compound or dispense pharmaceuticals, or sell, rent or lease equipment,
associated with the Therapies provided under the System; or (c) being employed
in an acute-care facility solely to provide products or services to in-patients
of that facility.  Section 16.2 also shall not apply to ownership by Franchise
Owner  or any Owner of less than one percent (1%) beneficial interest in the
outstanding equity securities of any publicly-held corporation.  Section 16.2
also shall not prohibit any person from owning an interest in other Option Care
franchises, or from being employed by any Option Care franchises.

    16.4 Enforcement of Covenants.  Franchise Owner and its Owners expressly
         ------------------------                                           
agree that the existence of any claims they may have against Franchisor, whether
or not arising from this Agreement, shall not constitute a defense to the
enforcement by Franchisor of the covenants in this Section 16.  Franchise Owner
and its Owners jointly and severally agree to pay all costs and expenses
(including reasonable attorneys' fees) incurred by Franchisor in connection with
the enforcement of this Section 16.

    16.5 Irreparable Injury.  Franchise Owner  and its Owners acknowledge that
         ------------------                                                   
Franchise Owner's violation of the terms of this Section 16 would result in
irreparable injury to Franchisor for which no adequate remedy at law may be
available, and Franchise Owner and its Owners accordingly agree that Franchisor
may seek an injunction prohibiting any conduct by Franchise Owner and its Owners
in violation of the terms of this Section 16.

    16.6 Employee Covenants.  At Franchisor's request, Franchise Owner agrees to
         ------------------                                                     
obtain execution of covenants similar to those set forth in this Section 16,
including covenants that are operative upon the termination of a person's
relationship with Franchise Owner, from supervisory personnel, officers and
directors, and other persons reasonably determined by Franchisor to be in a
position to use information gained from their association with Franchise Owner
to compete with the Franchise Owner and the System.  Every covenant required by
this Section 16.6 shall be in a form satisfactory to Franchisor, including,
without limitation, specific identification of Franchisor as a third party
beneficiary of such covenants with the independent right to enforce them.

         ------------------------                                               
liability company or a partnership, Franchise Owner agrees that the entity will
confine its activities to the operation of the Franchised Business throughout
the term of this Agreement.  Franchise Owner agrees to have a written
partnership agreement, unit ownership agreement or buy-sell agreement in effect
during the entire term of this Agreement.  Franchise Owner agrees to provide to
Franchisor information about Franchise Owner's organization and management,
including copies of documents, as may be reasonably specified by Franchisor from
time-to-time.  The requested information may include the following items as
applicable:

         17.1.1  Copies of Franchise Owner's Articles of Incorporation or
Partnership Agreement, or Unit Ownership Agreement, Bylaws, and any other
governing documents, and any amendments to any of these documents.

         17.1.2  A current list of the name and title of each officer and
director or managing partner, and a list of each owner of record or beneficial
owner of Franchise Owner showing the number of shares of each class of stock in
Franchise Owner owned by each shareholder, or the capital and profit interests
of each partner.  Franchise Owner also agrees to furnish a revised copy of these
lists to Franchisor each time a change occurs to the information.

         17.1.3  Franchise Owner shall maintain stop transfer instructions
against the transfer on its records of any equity securities.  If Franchise
Owner is a corporation, Franchise Owner shall legibly and conspicuously maintain

         Franchise Agreement with Option Care, Inc. dated _________19_____.

         17.1.4  If Franchise Owner is a partnership, or limited liability
company, the Partnership Agreement or Unit Ownership Agreement (as the case may

18. TAXES AND INDEBTEDNESS

    18.1 Franchise Owner agrees to promptly pay when due all taxes, accounts and
other indebtedness of every kind levied or assessed against, or incurred by,
Franchise Owner. Franchise Owner agrees to pay to Franchisor an amount equal to
any sales, gross receipts or similar tax (other than income tax) imposed on
Franchisor with respect to any payments to Franchisor required under this
Agreement, unless the tax is credited against income tax otherwise payable by
Franchisor.

    18.2 In the event of any bona fide dispute as to Franchise Owner's liability
for taxes, accounts, or other indebtedness, Franchise Owner may contest the
validity or the amount of the tax, account or indebtedness in accordance with
procedures of the taxing authority or 

                                       35
<PAGE>
 
applicable law; however, in no event shall Franchise Owner permit a tax sale or
seizure by levy of execution or similar writ or warrant, or attachment by a
creditor, to occur against the Franchised Business, any office, any improvements
to any office, or any other asset of Franchise Owner.

    18.3 Franchise Owner shall notify Franchisor in writing within five (5) days
of the commencement of any action, suit or proceeding, and of the issuance of
any order, writ, injunction, award or decree of any court, agency or other
governmental instrumentality, which may adversely affect the operation or
financial condition of the Franchised Business.

19. INDEPENDENT CONTRACTOR; AUTHORITY

    It is understood and agreed by the parties hereto that this Agreement does
not create a fiduciary relationship between them; that Franchise Owner shall be
an independent contractor and shall hold itself out to the public as an
independent contractor including in such manner as Franchisor may reasonably
specify; and that nothing in this Agreement is intended to constitute either
party an agent, legal representative, subsidiary, joint venturer, partner,
employee or servant of the other for any purpose whatsoever.

    It is understood and agreed that nothing in this Agreement authorizes
Franchise Owner to make any contract, agreement, warranty or representation on
Franchisor's behalf, or to incur any debt or other obligation in Franchisor's
name, and that Franchisor shall in no event assume liability for, or be deemed
liable under this Agreement as a result of, any such action or by reason of any
act or omission of Franchise Owner in its conduct of the Franchised Business, or
any claim or judgment arising therefrom against Franchisor.

20. INDEMNIFICATION

    20.1 Franchise Owner assumes sole responsibility for losses arising out of
the operation of the Franchised Business, and the acts or omissions of Franchise
Owner and its agents, servants and contractors.  Franchise Owner shall
indemnify, defend and hold Franchisor and its shareholders, partners, directors,
officers, employees and agents harmless against and to reimburse them for all
losses arising out of or in any way connected with the operation of the
Franchised Business or the acts or omissions of Franchise Owner or its agents,
servants or contractors.  These indemnities shall continue in full force and
effect subsequent to and notwithstanding the expiration or termination of this
Agreement.  "Losses", as used in this Section 20.1, shall include all
liabilities, penalties, costs, losses, damages, expenses, causes of action,
claims or judgments, including reasonable attorneys' fees and costs.

    20.2 Under no circumstances shall any person entitled to indemnity under
this Agreement be required or obligated to seek recovery from third parties or
otherwise mitigate their losses in order to maintain a claim against the
indemnifying party, nor shall a failure to seek such recovery or mitigate losses
in any way reduce the amounts recoverable from the indemnifying party.

21. APPROVALS AND WAIVERS

    Whenever this Agreement requires the prior approval or consent of
Franchisor, Franchise Owner shall make a timely written request to Franchisor,
and such approval or consent shall be obtained in writing signed by the
President or any Vice President of Franchisor.  No other communication from any
officer, employee or agent of Franchisor, whether oral or in writing, shall
constitute a valid approval or consent of Franchisor pursuant to this Section
21.

    Franchisor makes no warranties or guarantees upon which Franchise Owner may
rely, and assumes no liability or obligation to Franchise Owner, by providing
any waiver, approval, consent or suggestion to Franchise Owner in connection
with this Agreement, or by reason of any neglect, delay, or denial of any
request therefor.

    No delay, waiver, omission or forbearance on the part of Franchisor to
exercise any right, option, duty or power arising out of any breach or default
by Franchise Owner under any of the terms, provisions, covenants or conditions
hereof, shall constitute a waiver by Franchisor to enforce any such right,
option, duty or power as against Franchise Owner, or as to any subsequent breach
or default by Franchise Owner.

23. ENTIRE AGREEMENT

    This Agreement and the Exhibits attached hereto constitute the entire, full
and complete Agreement between Franchisor and Franchise Owner concerning the
subject matter hereof, and supersede all prior agreements, no other
representations having induced Franchise Owner to execute this Agreement.  No
representations, inducements, promises or agreements, oral or otherwise, not
embodied herein or attached hereto (unless of subsequent date) were made by
either party, and none shall be of any force or effect with reference to this
Agreement or otherwise, except for purposes of Section 14.1.13.  Franchisor is
nonetheless permitted, in its sole discretion, to reduce the scope of any
covenant or portion thereof set forth in Section 16, without Franchise Owner's
consent, effective immediately upon receipt by Franchise Owner of written
notice, and Franchise Owner agrees that it shall comply with the modified
covenant which shall be fully enforceable.  Except for those permitted to be
made by Franchisor hereunder, no amendment, change, or variance from this
Agreement shall be binding on either party unless mutually agreed to by the
parties and executed by their authorized officers or agents in writing.

24. SEVERABILITY AND CONSTRUCTION

    Except as expressly provided to the contrary in this Agreement, nothing in
this Agreement is intended, nor shall be deemed, to confer any rights or
remedies under or by reason of this Agreement upon any person or legal entity
other than Franchise Owner, Franchisor, Franchisor's officers, directors and
employees, and such of Franchise Owner's and Franchisor's respective successors
and assigns as may be contemplated and permitted by Section 13 hereof.

    Franchise Owner agrees that each promise or covenant of this Agreement that
may result from striking any portion or portions which a court may hold to be
unreasonable and unenforceable in a final decision to which Franchisor is a
party, or from reducing the scope of any promise or covenant to the extent
required to comply with such a court order, is separately enforceable to the
maximum extent permitted by law.

    All captions in this Agreement are intended solely for the convenience of
the parties, and none shall be deemed to affect the meaning or construction of
any provision hereof.

    All references herein to the masculine, neuter, singular or plural shall be
construed to include the masculine, feminine, neuter, singular or plural, where
applicable; and all acknowledgments, promises, covenants, agreements and
obligations herein made or undertaken 

                                       38
<PAGE>
 
by Franchise Owner shall be deemed jointly and severally undertaken by all those
executing this Agreement on behalf of Franchise Owner.

    This Agreement may be executed in several counterparts and each copy so
executed shall be deemed one and the same document.

25. APPLICABLE LAW

    This Agreement takes effect upon its acceptance and execution by Franchisor
in Illinois, and shall be interpreted and construed under the laws of Illinois,
which laws shall prevail in the event of any conflict of law; provided, however,
that if any of the provisions of this Agreement would not be enforceable under
the laws of Illinois, then such provisions shall be interpreted and construed
under the laws of the state in which the Franchised Business is located.

    The parties agree that any action brought by either party against the other
in any court, whether federal or state, shall be brought within the State of
Illinois in the Cook County judicial district and do hereby waive all questions
of personal jurisdiction or venue for the purpose of carrying out this
provision.

         No right or remedy conferred upon or reserved to Franchisor or
Franchise Owner by this Agreement is intended to be, nor shall be deemed,
exclusive of any other right or remedy herein or permitted by law or equity, but
each shall be cumulative of every other right or remedy.

         Nothing herein contained shall bar Franchisor's right to obtain
injunctive relief against threatened conduct that will cause it loss or damages,
under the usual equity rules, including the applicable rules for obtaining
restraining orders and preliminary injunctions.

26. ACKNOWLEDGMENTS

         Franchise Owner acknowledges that it has conducted an independent
investigation of the Franchised Business, and recognizes that the business
venture contemplated by this Agreement involves business risks and that the

$623,023.41                                             November 15, 1996
 
                                PROMISSORY NOTE
                                ---------------

FOR VALUE RECEIVED, including the cancellation of those certain Promissory Notes
between Convention Drug Center, Inc., a Nevada corporation ("Maker") and Option
Care, Inc., a California corporation ("Holder") dated, respectively, September
16, 1992, in the principal amount of $300,000 and November 29, 1994, in the
principal amount of $802,860.88, Maker  promises to pay to the order of Holder,
or to the registered holder, in the manner set forth below, the principal sum of
Six Hundred Twenty-Three Thousand Twenty-Three Dollars and Forty-One Cents
($623,023.41) plus interest accrued from and after November 15, 1996 on the
balance of the principal amount of this Note remaining from time to time unpaid
at a rate of interest equal to ten percent (10%) per annum, compounded annually.

The Principal amount of this Note together with all interest accrued thereon
shall be due and payable in forty-eight (48) equal consecutive monthly
installments in the amount of Fifteen Thousand Eight Hundred Forty-One Dollars
and Three Cents ($15,841.03), with the first installment due and payable on
December 15, 1996, and each of the next  forty-seven (47) installments due and
payable on the fifteenth day of each month thereafter, with the last such
installment due and payable on November 15, 2000.

Occurrence of one or more of the following events shall constitute an "Event of
Default:"

A.   Failure of the Maker to pay any installment due under this Note where such
failure has continued for a period of ten (10) days after its due date;

B.   At any time, (i) commencement by the Maker of a voluntary case under the
federal bankruptcy laws, as now or hereafter constituted or any other applicable
federal or state bankruptcy, insolvency or other similar law, (ii) consent by
the Maker to the appointment of a receiver, trustee, custodian, sequestrator or
other similar official for the Maker or any substantial part of its property, or
to the taking possession by any such official of any substantial part of the
property of the Maker, or (iii) making by the Maker of any assignment for the
benefit of creditors generally;

C.   Termination of the Maker's Franchise Agreement, as amended, with Option
Care, Inc.;

D.   Failure of Maker to pay for product ordered pursuant to Option Care, Inc.'s
product contracts within 45 days of invoice; or

E.   Failure to timely submit royalty reports and/or pay royalties by the date
prescribed in the Franchise Agreement from and after November 15, 1996.

Upon the occurrence of an Event of Default hereunder, the Holder may, at its
option, declare the entire unpaid Principal balance of the Note and all accrued
interest thereon to be due and payable. Upon the occurrence of an Event of
Default hereunder, the Holder may, at its option, escalate the interest rate to
eighteen percent (18%) for the remaining term of the Note.

If, at any time, the applicable interest rate hereunder is deemed by any
competent court of law, governmental agency, board, commission or tribunal, to
exceed the maximum rate of interest 
<PAGE>
 
permitted by applicable law, then, for such time as the applicable interest rate
hereunder would be deemed excessive, such interest rate shall be suspended and
this Note shall bear interest at the maximum rate permissible under such
applicable law, but thereafter, the former applicable interest rate hereunder
shall be reinstated.

All payments of Principal and interest hereunder shall be payable in lawful
money of the United States of America at the offices of Holder located in the
State of Illinois or at such other place as the Holder hereof may designate in
writing to the Maker.  If any payment of principal or interest hereunder shall
become due on a Saturday, Sunday or business holiday under the laws of the State
of Illinois or the United States of America, such payment shall be made on the
next succeeding business day and such extension shall be included in computing
any interest in respect of payment.

This Note may be prepaid in whole or in part at any time or from time to time
without premium or penalty.  All payments hereunder shall be applied first to
interest on the unpaid balance hereunder at the rate herein specified and then
to installments of principal in the inverse order of the maturity thereof.

The Maker agrees to pay, promptly and on demand by the Holder, all costs of
collection and all reasonable attorneys' fees paid or incurred by the Holder in
enforcing any of the Holder's rights hereunder.  The maker  waives presentment,
demand, notice, protest and all other demands and notices in connection with the
delivery, acceptance, performance, default or enforcement of this Note, asserts
to any extension or postponement of the time of any payment or any indulgence to
any substitution, exchange or release of collateral and to the addition or
release of any other party or person primarily or secondary liable.

In the event that Maker enters into a financing arrangement for the purpose of
repaying all indebtedness of Maker to the Bank of America and Golden State
Finance (collectively Bank of America and Golden State Finance shall be referred
to as "Secured Creditors") as well as terminating the financing statements of
the Secured Creditors, and does indeed effectively terminate any and all
financing statements of the Secured Creditors with the proper filing of Uniform
Commercial Code Form 3's, Holder will be willing to subordinate its current

                               SECURITY AGREEMENT


     This 15th day of November, 1996, Convention Center Drug, Inc. (hereinafter
called "DEBTOR"), for valuable consideration, receipt whereof is hereby
acknowledged, hereby grants to OPTION CARE, INC., 100 Corporate North, Suite

security interest in accounts receivable, contract rights, equipment, furniture,
fixtures, general intangibles, insurance proceeds, inventory, prescription
files, merchandise (including all drugs, prescription stock, proprietaries)
apparatus of every kind, nature and description, together with all accessories
thereto, now in the DEBTOR'S possession or control or hereafter to be acquired
by the DEBTOR, whether or not sold by or acquired from SECURED PARTY, all
additions and accessions thereto, substitutions therefor, as well as all
proceeds from the sale and proceeds of insurance thereon (hereinafter called
"Collateral") to secure the payment of liability and indebtedness of DEBTOR to
SECURED PARTY.  This agreement shall apply to all indebtedness, obligations or
liability of DEBTOR to SECURED PARTY reflected in that certain promissory note
entered into between DEBTOR and SECURED PARTY on even date herewith plus
interest accrued at the rate of ten (10%) percent on the unpaid balance until
paid in full (all hereinafter called the "Obligations").

     DEBTOR hereby warrants and covenants:

     1.   That except for the security interest granted hereby to DEBTOR, and
any security interest which has previously been granted to the Bank of America
and Golden State Finance (Bank of America and Golden State Finance shall
hereinafter collectively be referred to as "Other Creditors"), or in the event
that DEBTOR enters into a financing arrangement with a single replacement
creditor ("Replacement Creditor") for the purpose of repaying all indebtedness
of DEBTOR to the Other Creditors as well as terminating the financing statements
of the Other Creditors, and does indeed effectively terminate any and all
financing statements of the Other Creditors with the proper filing of Uniform
Commercial Code Form 3's, then except for that security interest granted to
Replacement Creditor in an amount not to exceed Six Hundred Thousand Dollars
($600,000) of the Collateral,  DEBTOR is or will be the owner of the Collateral
free from any secured adverse lien, security interest or encumbrance;  and that
DEBTOR will defend the Collateral against all claims and demands of all persons
at any time claiming the same or any interest therein;

     2.   In the event that the indebtedness of DEBTOR to the Replacement
Creditor or any Other Creditor exceeds $600,000 then SECURED PARTY'S interest in
the Collateral shall be deemed to be in pari passu with the interest in the
collateral of the Creditor most preferred under the law;

     3.   That the Collateral is not used or bought primarily for personal,
family or household purposes;
<PAGE>
 
     4.   That the Collateral will be kept at the DEBTOR'S offices located at
3900 W. Charleston Blvd., Suite Y, Las Vegas, Nevada 89102, 2851 North Tenaya,
Las Vegas, Nevada 89128, and 921 South Highway, Suite 406, Pahrump, Nevada 89048
and that there are no other places of business of DEBTOR;

     5.   That at the request of SECURED PARTY, DEBTOR will join with SECURED
PARTY in executing one or more Financing Statements pursuant to the Uniform
Commercial Code
in form satisfactory to SECURED PARTY and will file the same in all public
offices wherever filing is deemed by SECURED PARTY to be necessary or desirable;

     6.   That DEBTOR will not sell or offer to sell in bulk or otherwise
transfer the Collateral in bulk or any interest therein without the written
consent of SECURED PARTY provided, however, that DEBTOR shall be entitled to
sell the Collateral in the ordinary and usual course of business;

     7.   That DEBTOR will, at all times, maintain in full force and effect
insurance with respect to the Collateral against risks encompassed within the
standard policy of fire insurance with extended coverage endorsement, theft and
other risks as SECURED PARTY may require, and written by such company or
companies as may be satisfactory to SECURED PARTY, such insurance to be payable
to SECURED PARTY and DEBTOR as their interests may appear.  All such policies of
insurance shall provide for not less than ten (10) days written notice of
cancellations to SECURED PARTY and, at the request of SECURED PARTY, shall be
delivered to and held by it. SECURED PARTY may act as attorney-in-fact for
DEBTOR in obtaining, adjusting, settling and cancelling such insurance and
endorsing any drafts;

     8.   That DEBTOR will keep the Collateral free from any adverse lien,
security interest or encumbrance and in good order and repair and will not waste
or destroy the Collateral or any part thereof; that DEBTOR will not use the
Collateral in violation of any statute or ordinance; and that SECURED PARTY may
examine and inspect the Collateral at any time, wherever located;

     9.   This security interest covers all property of the same character as
that covered by this agreement which the DEBTOR may hereafter acquire at any
time until termination of this security agreement;

               following the invoice therefor from SECURED PARTY.;

          (b)  DEBTOR shall submit all royalty reports when due;

          (c)  DEBTOR shall pay each month's current royalties and
               continuing/national education payments when due;

          (d)  Franchise Owner shall deliver to Option Care no later than
               November 15, 1996 two signed UCC-1s, securing the accounts
               receivable, equipment and other assets of Franchise Owner; and

                                       2
<PAGE>
 
          (e)  Franchise Owner covenants and agrees not to increase its
               indebtedness (i) to any third party other than a shareholder of
               the DEBTOR, (ii) other than to the Replacement Creditor and (iii)
               other than normal payables or expenses accrued in the ordinary
               course of business without first obtaining the written consent of
               SECURED PARTY; and

     11.  That DEBTOR will pay promptly when due all taxes and assessments upon
the collateral or for its use or operation or upon this agreement or upon any
note or notes evidencing the Obligations.

     At its option, SECURED PARTY may discharge taxes, liens or security
interests or other encumbrances at any time levied or placed on the Collateral,
may pay for insurance on the Collateral and may pay for the maintenance and
preservation of the Collateral.  DEBTOR agrees to reimburse SECURED PARTY on
demand for any payment made, or expense incurred by SECURED PARTY pursuant to
the foregoing authorization.

     Until default, DEBTOR may have possession of the Collateral and use it in
any lawful manner not inconsistent with this agreement and not inconsistent with
any policy of insurance thereon.

DEBTOR shall be in default under this Agreement upon the happening of any of the
following events or conditions without opportunity to cure or notice of the
default:

     (a)  default in the payment or performance of any obligation, covenant or
liability contained or referred to herein or in any note evidencing the same;

     (b)  any warranty, representation or statement made or furnished to SECURED
PARTY by or on behalf of DEBTOR proves to have been false in any material
respect when made or furnished;

     (c)  any event which results in the acceleration of the maturity of the
indebtedness of DEBTOR to others under any indenture, agreement or undertaking;

     (d)  loss, theft, damage, destruction, unauthorized sale or encumbrance to
or of any of the Collateral, or the making of any levy, seizure or attachment
thereof or thereon; or

     (e)  death, dissolution, termination of existence, insolvency, business
failure, appointment of a receiver of any part of the property of, assignment

Obligations secured hereby immediately due and payable and shall have all the
remedies of a secured party under the Uniform Commercial Code of the applicable
state.   SECURED PARTY may require DEBTOR

to assemble the Collateral and make it available to SECURED PARTY at a place to
be designated by SECURED PARTY which is reasonably convenient to both parties.

DEBTOR reasonable notice of the time and place of any public sale thereof or of
the time after which any private sale or any other intended disposition thereof
is to be made.

mailed, postage prepaid, to the address of DEBTOR shown at the beginning of this
agreement at least ten (10) days before the time of the declaration of default
or sale of Collateral.

     No waiver by SECURED PARTY of any default shall operate as a waiver of any
other default or of the same default on a future occasion.

     All rights of SECURED PARTY hereunder shall inure to the benefit of its
successors and assigns, and all obligations of DEBTOR shall bind its successors
or assigns.

     This agreement shall become effective when it is signed by DEBTOR.

                         EXECUTIVE SEVERANCE AGREEMENT
                         -----------------------------



     This Executive Severance Agreement (the "Agreement") is made and entered
into as of this _28_ day of June, 1996, by and between Option Care, Inc., a
Delaware corporation (the "Company") and Erick E. Hanson, an individual residing
in the State of Illinois (the "Executive").

                             W I T N E S S E T H:

     WHEREAS, the Board of Directors of the Company (the "Board"), recognizes
that the possibility of a Change in Control (as hereinafter defined in Section
1.1), exists and that the possibility of or the occurrence of a Change in
Control may result in significant distractions of its key management personnel
because of the uncertainties inherent in such a situation; and

     WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its shareholders that the Company be able to receive
and rely upon Executive's advice without concern that the Executive might be
distracted by the personal uncertainties and risks associated with a Change in
Control; and

     WHEREAS, in order to induce the Executive to remain in the employ of the
Company, particularly in the event of the occurrence of a Change in Control, and
for other good and valuable consideration, the Company and the Executive desire
to enter into this Agreement; and
 
     WHEREAS, the Company and Executive each hereby acknowledge that this
Agreement is not intended to be, and shall not be construed as, an express or
implied contract of employment between the Company and the Executive;

     NOW, THEREFORE, in consideration of the respective agreements of the
parties contained herein, it is agreed as follows:
<PAGE>
 
                                   SECTION 1
                                  DEFINITIONS

     1.1  Definitions.  In addition to terms which may be defined within
          -----------                                                   
specific Sections of this Agreement, the following terms shall have the
following meanings when used herein with initial capital letters:

     (a)  "AFFILIATE" shall mean, as to a specified Person, another Person that
directly, or indirectly through one or more intermediaries, controls or is
controlled by, or is under common control with, the specified Person, within the
meaning of such terms as used in Rule 405 under the Securities Act of 1933, as
amended, or any successor rule.

     (b)  "APPLICABLE ANNUAL EARNINGS" shall mean the sum of the Executive's
Base Salary, plus 100% of the Executive's Bonus for personal services on behalf
of the Company for the calendar year in which the Termination occurs (except
that if Executive is subject to a Constructive Termination for Good Reason
because his Base Salary or Bonus is reduced, then the current annual Base Salary
and Bonus used to determine Applicable Annual Earnings shall be the annual Base
Salary in effect or Bonus, as applicable, immediately prior to such Constructive
Termination for Good Reason). Applicable Annual Earnings shall include
Executive's current annual Base Salary and Bonus whether or not paid on a
deferred basis, including, without limitation, amounts contributed by or on
behalf of Executive under a Company sponsored plan, such as (i) a plan described
in Section 125 or 401(k) of the Internal Revenue Code of 1986, as amended, or
(ii) any "excess benefit plan" as defined in the Employee Retirement Income
Security Act of 1974, as amended. Notwithstanding the preceding provisions of
this paragraph, Applicable Annual Earnings do not include any income
attributable to stock options, stock appreciation rights, performance awards,
dividend credits, and restricted stock granted under, and dividends on shares
acquired pursuant to, any stock option plan, restricted stock plan or
performance unit plan.

     (c)  "BASE SALARY" shall mean the sum of the Executive's current annual
base salary, including, if applicable, any car allowance, club dues or other
payments paid to or on behalf of the Executive by the Company determined, in
each case, using the highest rate in effect up to and including the Termination
Date and whether or not actually paid.
<PAGE>
 
     (d)  "BONUS" means an amount paid to Executive on an annual basis which is
equal to forty percent (40%) of the Executive's then current Base Salary.

     (e)  "CAUSE" shall mean that a majority of the Company's Board of Directors
(the "Board") shall have determined that the Executive (i) willfully and
continually failed to substantially perform his duties with the Company (other
than a failure resulting from Executive's incapacity due to illness, physical or
mental disability or other incapacity) and such failure continues for a period
of thirty (30) days after the Board has given written notice to Executive
providing a reasonable description of the basis for the determination that
Executive has failed to perform his duties, (ii) has been convicted of a felony,
(iii) engaged in conduct constituting willful malfeasance in connection with his
employment which is materially and demonstrably injurious to the Company and its
subsidiaries taken as a whole.  No act, or failure to act, on Executive's part,
shall be considered "willful" for purposes of (i) or (iii) above unless he has
acted or failed to act with an absence of good faith and without a reasonable
belief that his action or failure to act was in the best interests of the
Company. Notwithstanding anything contained in this Agreement to the contrary,
no failure to perform by Executive after Notice of Termination (as herein
defined) is given by Executive shall constitute Cause for purposes of this
Agreement.  No determination of Cause shall be final until the Executive and his
legal advisors are given an opportunity to meet with the Board, contest the
basis for termination, and demonstrate that Executive's continued employment is
in the best interests of the Company.

     (f)  "CONSTRUCTIVE TERMINATION FOR GOOD REASON" shall mean a termination of
employment with the Company by the Executive pursuant to the provisions of
Section 2.2.

     (g)  CHANGE IN CONTROL.  For purposes of this Agreement, a "Change in
Control" shall be deemed to have occurred as of the date that one or more of the
following occurs:

          (i)    Individuals who, as of the date hereof, constitute the entire
     Board of Directors of the Company ("Incumbent Directors") cease for any
     reason to constitute at least a majority of the Board; provided, however,
     that any individual becoming a director subsequent to the date hereof whose

                                       3
<PAGE>
 
     election, or nomination for election by the Company's stockholders, was
     approved by a vote of at least a majority of the then Incumbent Directors
     shall be considered as though such individual was an Incumbent Director,
     but excluding, for this purpose any such individual whose initial
     assumption of office occurs as a result of either an actual or threatened
     election contest, as such terms are used in Rule 14a-11 under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act") or other
     actual or threatened solicitation of proxies or consents by or on behalf of
     any Person other than the Board; provided, further, that in the event
     Kapoor (as herein defined) at any time determines to achieve representation
     on the Company's Board of Directors approximately equal to his then
     ownership percentage of the Company's common stock, his implementation of
     such determination through the election of Kapoor Affiliates as directors
     of the Company shall not be deemed to be a Change in Control and such
     Kapoor Affiliates shall constitute Incumbent Directors;

          (ii)   The stockholders of the Company shall approve (A) any merger,
     consolidation or recapitalization of the Company (or, if the capital stock
     of the Company is affected, any subsidiary of the Company), or any sale,
     lease, or other transfer (in one transaction or a series of transactions
     contemplated or arranged by any party as a single plan) of all or
     substantially all of the assets of the Company (each of the foregoing being
     an "Acquisition Transaction") where (1) the stockholders of the Company
     immediately prior to such Acquisition Transaction would not immediately
     after such Acquisition Transaction beneficially own, directly or
     indirectly, shares or other ownership interests representing in the
     aggregate eighty percent (80%) or more of (a) the then outstanding common
     stock or other equity interests of the corporation or other entity
     surviving or resulting from such merger, consolidation or recapitalization
     or acquiring such assets of the Company, as the case may be (the "Surviving
     Entity") (or of its ultimate parent corporation or other entity, if any),
     and (b) the Combined Voting Power (as herein defined) of the then
     outstanding Voting Securities (as herein defined) of the Surviving Entity
     (or of its ultimate parent corporation or other entity, if any) or (2) the
     Incumbent Directors at the time of the initial approval of such Acquisition
     Transaction would not immediately after such 

                                       4
<PAGE>
 
     Acquisition Transaction constitute a majority of the Board of Directors, or
     similar managing group, of the Surviving Entity (or of its ultimate parent
     corporation or other entity, if any), or (B) any plan or proposal for the
     liquidation or dissolution of the Company; or

          (iii)  Any Person, other than Kapoor, shall be or become the
     beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange
     Act), directly or indirectly, of securities of the Company representing in
     the aggregate more than fifty percent (50%) of either (A) the then
     outstanding shares of common stock of the Company ("Common Shares") or (B)
     the Combined Voting Power of all then outstanding Voting Securities of the
     Company.

     (h)  "COMBINED VOTING POWER" shall mean the aggregate votes entitled to be
cast generally in the election of the Board of Directors, or similar managing
group, of a corporation or other entity by holders of then outstanding Voting
Securities of such corporation or other entity.

six consecutive months to perform his duties, because of illness, physical or
mental disability or other incapacity, or (ii) at such earlier time as Executive
submits satisfactory medical evidence that he has an illness, physical or mental
disability or other incapacity which is expected to prevent him from returning
to the performance of his work duties for six months or longer.

     (j)  "EMPLOYEE BENEFITS" means the perquisites, benefits and service credit
for benefits as provided under any and all employee retirement income and

self-insured by the Company), disability, salary continuation, expense
reimbursement, and other similar employee benefit policies, plans, programs or
arrangements that may now exist or any equivalent successor policies, plans,
programs or arrangements that may be adopted hereafter by the Company, providing
perquisites, benefits and service credit for benefits at least as great in the
aggregate as are payable thereunder prior to a Change in Control; provided,

limitation, any corporation, partnership, Company, joint venture, association or

     conclusive and binding upon the parties hereto provided it has been made in
     good faith and in all events will be presumed to have been made in good

     Control, including without limitation a change in the scope of the business
     or other activities for which the Executive was responsible immediately
     prior to the Change in Control, which has rendered the Executive
     substantially unable to carry out, or has caused the Executive to suffer a
     substantial reduction in, any of the authorities, powers, functions,
     responsibilities, or duties attached to the position held by the Executive

     changed, to any location which is in excess of 25 miles from the location
     thereof immediately prior to the Change in Control, or requires the
     Executive to travel away from the Executive's office in the course of
     discharging the Executive's responsibilities or duties hereunder at least
     20% more (in terms of aggregate days in any calendar year or in any
     calendar quarter when annualized for purposes of comparison to any prior

     with the Company, immediately prior to the Change in Control without, in

                     RIGHTS AND BENEFITS UPON TERMINATION

     3.1. Termination Payments.  In the event Executive shall become entitled to
          --------------------

a Constructive Termination for Good Reason under Section 2.2 within the
Severance Period (hereinafter collectively referred to as a "Termination"), the
Company agrees to provide or cause to be provided to Executive the following
rights and benefits:

     (a)  The Company shall pay to the Executive in a lump sum, by certified
check, within ten (10) "business days" (which for purposes of this Agreement
shall mean any day other than Saturday, Sunday, or public holiday under the laws
of the State of Illinois) after the Termination Date, or, at the election of
Executive, in twelve (12) equal monthly installments, an amount equal to the
aggregate of the following:

          i.   The sum of:

               (i)   The Executive's proportionate amount of the Base Salary
          through the Termination Date, to the extent not theretofore paid; plus

               (ii)  Any compensation previously deferred by the Executive
          (together with any accrued interest or earnings thereon) and any
          accrued vacation pay, in each case to the extent not theretofore paid.

          ii.  An amount equal to two hundred percent (200%) of the Executive's
     Applicable Annual Earnings.

                                       10
<PAGE>
 
     (b)  For the balance of the Severance Period, but in no event for less than
one year, the Company will arrange to provide the Executive with all Employee
Benefits substantially similar to those which the Executive was receiving or
entitled to receive immediately prior to the Termination Date, except that the
level of any such Employee Benefits to be provided to the Executive may be
reduced in the event of a corresponding reduction applicable generally to all
recipients of or participants in such Employee Benefits, and the Severance
Period will be considered service with the Company for the purpose of
determining service credits and benefits due and payable to the Executive under
the Company's retirement income, supplemental executive retirement, and other
benefit plans of the Company applicable to the Executive, the Executive's
dependents, or the Executive's beneficiaries immediately prior to the
Termination Date.  If and to the extent that any benefit described in the
immediately preceding sentence is not or cannot be paid or provided under any
policy, plan program or arrangement of the Company, then the Company will itself

if applicable, the Executive's dependents and Beneficiaries.

     3.2  Bonus Payment.  In the event (a) of a Change of Control shall be

consummated during calendar year 1996, or (b) a Termination in 1996 during the
Severance Period or in 1997 but prior to payment of the Bonus for calendar year
1996, then, within thirty (30) days of any such event, the Company shall pay to
Executive one hundred percent (100%) of the Bonus which would be payable to
Executive for 1996, which Bonus the Company and Executive agree shall be equal
to $90,000.

                                  MITIGATION

     4.1  No Duty to Mitigate.  In no event shall the Executive be obligated to
          -------------------                                                  
seek other employment or take any other action by way of mitigation of the
amount payable to the Executive under any of the provisions of this agreement
and such amounts shall not be reduced whether or not the Executive obtains other
employment.

                                   SECTION 5
                              ADDITIONAL PAYMENTS

     In addition to the amounts payable to the Executive pursuant to Section 3,
the Company shall make the following payments to the Executive to the extent
applicable:

     5.1. Change of Control Bonus.  In the event a Change of Control is
          -----------------------                                      
consummated while this Agreement is in effect (the "Transaction"), the Company
agrees to pay to Executive within thirty (30) days of the consummation of the
Transaction, the sum of One Hundred Fifty Thousand Dollars ($150,000) in partial
recognition of the Executive's efforts to bring about the Transaction and of the
value added to the Company during the Executive's tenure with the Company.

     5.2. Excise Tax Payment.
          ------------------ 

     (a)   Notwithstanding anything contained in this Agreement to the
contrary, in the event that any payment or distribution to or for the benefit of
the Executive, whether paid or payable or distributed or distributable pursuant
to the terms of this Agreement or otherwise in connection with, or arising out
of, his employment with the Company (a "Payment" or "Payments"), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code"), or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any interest and penalties, are collectively referred to as the "Excise Tax"),
then the Executive shall be entitled to receive an additional payment (a "Gross-
Up Payment") in an amount such that after payment by the Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax, imposed upon the Gross-up Payment, the Executive
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.

     (b)   a determination shall be made as to whether and when a Gross-Up
Payment is required pursuant to this Section 5.2(b) and the amount of such Gross
Up Payment, such determination to be made within fifteen (15) business days of
the Termination Date, or such other time as requested by the Company or by the
Executive (provided the Executive reasonably believes that any of the Payments
may be subject to the Excise Tax). Such determination

                                       12
<PAGE>
 
shall be made by a national independent accounting firm selected by the
Executive (the "Accounting Firm"). All fees, costs and expenses (including, but
not limited to, the cost of retaining experts) of the Accounting Firm shall be
borne by the Company and the Company shall pay such fees, costs and expenses as
they become due. The Accounting Firm shall provide detailed supporting
calculations, acceptable to the Executive, both to the Company and the
Executive. The Gross-Up Payment, if any, as determined pursuant to this Section
5.2 shall be paid by the Company to the Executive within five (5) business days
of the receipt of the Accounting Firm's determination. If the Accounting Firm
determines that no Excise Tax is payable by the Executive with respect to a
Payment or Payments, it shall furnish the Executive with an unqualified opinion
that no Excise Tax will be imposed with respect to any such Payment or Payments.
Any such initial determination by the Accounting Firm of the Gross-Up Payment
shall be binding upon the Company and the Executive subject to the application
of Section 5.2(c).

     (c)  As a result of the uncertainty on the application of Sections 4999 and
280G of the Code, it is possible that a Gross-Up Payment (or a portion thereof)
will be paid which should not have been paid (an "Overpayment") or a Gross-Up
Payment (or a portion thereof) which should have been paid will not have been
paid (an "Underpayment"). An Underpayment shall be deemed to have occurred upon
notice (formal or informal) to the Executive from any governmental taxing
authority that the tax liability of the Executive (whether in respect of the
then current taxable year of the Executive or in respect of any prior taxable
year of the Executive) may be increased by reason of the imposition of the
Excise Tax on a Payment or Payments with respect to which the Company has failed
to make a sufficient Gross-Up Payment. An Overpayment shall be deemed to have
occurred upon a "Final Determination" (as hereinafter defined) that the Excise
Tax should not be imposed upon a Payment or Payments with respect to which the
Executive has previously received a Gross-Up Payment. A Final Determination
shall be deemed to have occurred when the Executive has received from the
applicable governmental taxing authority a refund of taxes or other reduction in
his tax liability by reason of the Overpayment and upon either (i) the date of
determination as made by, or an agreement is entered into with, the governmental
taxing authority which finally and conclusively binds that Executive and such
taxing authority, or in the event that a claim 

                                       13
<PAGE>
 
is brought before a court of competent jurisdiction, the date upon which a final
determination has been made by such court and either all appeals have been taken
and finally resolved or the time for all appeals has expired or (ii) the
expiration of the statute of limitations with respect to the Executive's
applicable tax return. If an Underpayment occurs, the Executive shall promptly
notify the Company and the Company shall pay to the Executive at least five (5)
business days prior to the date on which the applicable governmental taxing
authority has requested payment, an additional Gross-up Payment equal to the
amount of the Underpayment plus any interest and penalties imposed on the
Underpayment. If an Overpayment occurs, the amount of the Overpayment shall be
treated as a loan by the Company to the Executive and the Executive shall,
within ten (10) business days of the occurrence of such Overpayment, pay to the
Company the amount of the Overpayment plus interest at an annual rate equal to
the rate provided for in Section 1274(b)(2)(B) of the Code from the date the
Gross-Up Payment (to which the Overpayment relates) was paid to the Executive.

     (d)  Notwithstanding anything contained in this Agreement to the contrary,
in the event it is determined that an Excise Tax will be imposed on any Payment
or Payments, the Company shall pay to the applicable governmental taxing
authorities as Excise Tax withholding, the amount of the Excise Tax that the
Company has actually withhold from the Payment or Payments.

                            LEGAL FEES AND EXPENSES

     6.1. Retention of Counsel.  It is the intent of the Company that the
          --------------------                                           
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of the Executive's
rights to compensation upon a Termination by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended
to be extended to the Executive hereunder. Accordingly, if it should appear to
the Executive that the Company has failed to comply with any of its obligations
under this Agreement or in the event that the Company or any other person takes
or threatens to take any action to declare the Agreement to pay Executive
compensation upon a Termination void or unenforceable, or institutes any
litigation 

                                       14
<PAGE>
 
or other action or proceeding designed to deny, or to recover from, the
Executive the benefits provided or intended to be provided to the Executive
hereunder, the Company irrevocably authorizes the Executive from time to time to
retain counsel of the Executive's choice, at the expense of the Company as
hereinafter provided, to advise and represent the Executive in connection with
any such interpretation, enforcement or defense, including without limitation
the initiation or defense of any litigation or other legal action, whether by or
against the Company or any Company director, officer, stockholder, or other
person affiliated with the Company, in any jurisdiction.

     6.2. Waiver of Conflict.  Notwithstanding any existing or prior attorney-
          ------------------                                                 
client relationship between the Company and such counsel, the Company
irrevocably consents to the Executive's entering into an attorney-client
relationship with such counsel, and in that connection the Company and the
Executive agree that a confidential relationship will exist between the
Executive and such counsel.

     6.3. Reimbursement of Expenses of Counsel.  Without regard to whether the
          ------------------------------------                                
Executive prevails in whole or in part, in connection with any of the foregoing,
the Company will pay and be solely financially responsible for any and all
attorneys' and related fees and expenses incurred by the Executive in connection
with any of the matters set forth in this Section 6.


                                   SECTION 7

          ----------------------                                       
Agreement will create any right or duty on the part of the Company or the
Executive to have the Executive remain in the employ of the Company prior to or
following any Change in Control, it being acknowledged and agreed by and between
the Company and the Executive that the Executive's employment with the Company
is and shall continue to be terminable "at will" by either party.

     7.2. Termination Prior to Change in Control.  Any termination by the
          --------------------------------------                         
Company of the employment of the Executive, other than for death or Cause, or
the removal of the Executive from any office or 

                                       15
<PAGE>
 
position in the Company, other than for Cause, following the commencement of any
discussion with a third person that results in a Change in Control within 90
calendar days after such termination or removal shall be deemed to be a
Termination of the Executive's employment after a Change in Control for purposes
of this Agreement.


                                   SECTION 8
                                     TERM

     8.1. Term.  The term of this Agreement shall be deemed to commence and be
          ----

the parties may agree.

     8.2. Termination for Death, Disability or Outside of the Severance Period.
          --------------------------------------------------------------------  
Except with respect to the provisions of this Agreement that provide for
payments to be made to Executive after a Termination, or that impose obligations
upon the Company or grant rights that may be exercised by Executive after a
Termination, this Agreement shall terminate automatically without further action
by either of the parties hereto upon the death or Disability of Executive or the
termination of Executive's employment with the Company for any reason or no
reason that do not occur in the Severance Period, in accordance with Executive's
status as an employee at will.

                                   SECTION 9

                         EXECUTIVE SEVERANCE AGREEMENT
                         -----------------------------



     This Executive Severance Agreement (the "Agreement") is made and entered
into as of this 28 day of June, 1996, by and between Option Care, Inc., a
Delaware corporation (the "Company") and ___J. Jeffery Fox__________________, an
individual residing in the State of Illinois (the "Executive").

                              W I T N E S S E T H:

     WHEREAS, the Board of Directors of the Company (the "Board"), recognizes
that the possibility of a Change in Control (as hereinafter defined in Section
1.1), exists and that the possibility of or the occurrence of a Change in
Control may result in significant distractions of its key management personnel
because of the uncertainties inherent in such a situation; and

     WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its shareholders that the Company be able to receive
and rely upon Executive's advice without concern that the Executive might be
distracted by the personal uncertainties and risks associated with a Change in
Control; and

     WHEREAS, in order to induce the Executive to remain in the employ of the
Company, particularly in the event of the occurrence of a Change in Control, and
for other good and valuable consideration, the Company and the Executive desire
to enter into this Agreement; and
 
     WHEREAS, the Company and Executive each hereby acknowledge that this
Agreement is not intended to be, and shall not be construed as, an express or
implied contract of employment between the Company and the Executive;

     NOW, THEREFORE, in consideration of the respective agreements of the
parties contained herein, it is agreed as follows:
<PAGE>
 
                                   SECTION 1
     DEFINITIONS

     1.1  Definitions.  In addition to terms which may be defined within
          -----------                                                   
specific Sections of this Agreement, the following terms shall have the
following meanings when used herein with initial capital letters:

     (a)  "AFFILIATE" shall mean, as to a specified Person, another Person that
directly, or indirectly through one or more intermediaries, controls or is
controlled by, or is under common control with, the specified Person, within the
meaning of such terms as used in Rule 405 under the Securities Act of 1933, as
amended, or any successor rule.

     (b)  "BASE SALARY" shall mean the sum of the Executive's current annual
base salary, including, if applicable, any car allowance, club dues or other
payments paid to or on behalf of the Executive by the Company determined, in
each case, using the highest rate in effect up to and including the Termination
Date and whether or not actually paid.

     (c)  "BONUS" means an amount paid to Executive on an annual basis which is
equal to thirty percent (30%) of the Executive's then current Base Salary.

     (d)  "CAUSE" shall mean that a majority of the Company's Board of Directors
(the "Board") shall have determined that the Executive (i) willfully and
continually failed to substantially perform his duties with the Company (other
than a failure resulting from Executive's incapacity due to illness, physical or
mental disability or other incapacity) and such failure continues for a period
of thirty (30) days after the Board has given written notice to Executive
providing a reasonable description of the basis for the determination that
Executive has failed to perform his duties, (ii) has been convicted of a felony,
(iii) engaged in conduct constituting willful malfeasance in connection with his
employment which is materially and demonstrably injurious to the Company and its
subsidiaries taken as a whole.  No act, or failure to act, on Executive's part,
shall be considered "willful" for purposes of (i) or (iii) above unless he has
acted or failed to act with an absence of good faith and without a reasonable
belief that his action or failure to act was in the best interests of the
Company. Notwithstanding anything contained in this Agreement to the contrary,
no failure to perform by Executive after Notice of 
<PAGE>
 
Termination (as herein defined) is given by Executive shall constitute Cause for
purposes of this Agreement. No determination of Cause shall be final until the

Board, contest the basis for termination, and demonstrate that Executive's
continued employment is in the best interests of the Company.

     (e)  "CONSTRUCTIVE TERMINATION FOR GOOD REASON" shall mean a termination of
employment with the Company by the Executive pursuant to the provisions of
Section 2.2.

     Board of Directors of the Company ("Incumbent Directors") cease for any
     reason to constitute at least a majority of the Board; provided, however,
     that any individual becoming a director subsequent to the date hereof whose
     election, or nomination for election by the Company's stockholders, was
     approved by a vote of at least a majority of the then Incumbent Directors
     shall be considered as though such individual was an Incumbent Director,
     but excluding, for this purpose any such individual whose initial

     actual or threatened solicitation of proxies or consents by or on behalf of
     any Person other than the Board; provided, further, that in the event
     Kapoor (as herein defined) at any time determines to achieve representation

                      RIGHTS AND BENEFITS UPON TERMINATION

     3.1. Termination Payments.  In the event Executive shall become entitled to
          --------------------                                                  
receive the rights and benefits described in this Section as a result of the
termination by the Company under Section 2.1 or a Constructive Termination for
Good Reason under Section 2.2 within the Severance Period (hereinafter
collectively referred to as a "Termination"), the Company agrees to provide or
cause to be provided to Executive the following rights and benefits:

     (a) The Company shall pay to the Executive in a lump sum, by certified
check, within ten (10) "business days" (which for purposes of this Agreement
shall mean any day other than Saturday, Sunday or public holiday under the laws
of the State of Illinois) after the Termination Date, or, at the election of
Executive, in twelve (12) equal monthly installments, an amount equal to the

              (i)  The Executive's proportionate amount of the Base Salary
          through the Termination Date, to the extent not theretofore paid; plus

              (ii) Any compensation previously deferred by the Executive
          (together with any accrued interest or earnings 

                                       9

     Base Salary.

     (b)  For the balance of the Severance Period, but in no event for less than
one year, the Company will arrange to provide the Executive with all Employee
Benefits substantially similar to those which the Executive was receiving or
entitled to receive immediately prior to the Termination Date, except that the
level of any such Employee Benefits to be provided to the Executive may be
reduced in the event of a corresponding reduction applicable generally to all
recipients of or participants in such Employee Benefits, and the Severance
Period will be considered service with the Company for the purpose of
determining service credits and benefits due and payable to the Executive under
the Company's retirement income, supplemental executive retirement, and other
benefit plans of the Company applicable to the Executive, the Executive's
dependents, or the Executive's beneficiaries immediately prior to the
Termination Date.  If and to the extent that any benefit described in the

pay or provide for the payment of such Employee Benefits to the Executive, and,
if applicable, the Executive's dependents and Beneficiaries.

consummated during calendar year 1996, or (ii) a Termination shall occur in 1996
during the Severance Period or in 1997, but prior to payment of the Bonus for
calendar year 1996, then, within thirty (30) days of any such event, the Company
shall pay to Executive one hundred percent (100%) of the Bonus which would
otherwise be payable to Executive for 1996.

     (b)  In the event of a Termination during the Severance Period, but after
January 1, 1997, then, in addition to the payments otherwise payable under

the product of (i) thirty percent (30%) of Executive's Base Salary and (ii) a
fraction, the numerator of which is the number of days completed in 1997 through
the Termination Date, and the denominator of which is 365.

                              ADDITIONAL PAYMENTS

     In addition to the amounts payable to the Executive pursuant to Section 3,
the Company shall make the following payments to the Executive to the extent
applicable:

     5.1. Excise Tax Payment.
          ------------------ 

     (a)    Notwithstanding anything contained in this Agreement to the
contrary, in the event that any payment or distribution to or for the benefit of
the Executive, whether paid or payable or distributed or distributable pursuant
to the terms of this Agreement or otherwise in connection with, or arising out
of, his employment with the Company (a "Payment" or "Payments"), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code"), or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any interest and penalties, are collectively referred to as the "Excise Tax"),
then the Executive shall be entitled to receive an additional payment (a "Gross-
Up Payment") in an amount such that after payment by the Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax, imposed upon the Gross-up Payment, the Executive
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.

     (b) A determination shall be made as to whether and when a Gross-Up Payment
is required pursuant to this Section 5.1(b) and the amount of such Gross Up
Payment, such determination to be made within fifteen (15) business days of the
Termination Date, or such other time as requested by the Company or by the
Executive 

                                       11
<PAGE>
 
(provided the Executive reasonably believes that any of the Payments may be
subject to the Excise Tax). Such determination shall be made by a national
independent accounting firm selected by the Executive (the "Accounting Firm").
All fees, costs and expenses (including, but not limited to, the cost of
retaining experts) of the Accounting Firm shall be borne by the Company and the
Company shall pay such fees, costs and expenses as they become due. The
Accounting Firm shall provide detailed supporting calculations, acceptable to
the Executive, both to the Company and the Executive. The Gross-Up Payment, if
any, as determined pursuant to this Section 5.1 shall be paid by the Company to
the Executive within five (5) business days of the receipt of the Accounting
Firm's determination. If the Accounting Firm determines that no Excise Tax is
payable by the Executive with respect to a Payment or Payments, it shall furnish
the Executive with an unqualified opinion that no Excise Tax will be imposed
with respect to any such Payment or Payments. Any such initial determination by
the Accounting Firm of the Gross-Up Payment shall be binding upon the Company
and the Executive subject to the application of Section 5.1(c).

     (c)  As a result of the uncertainty on the application of Sections 4999 and
280G of the Code, it is possible that a Gross-Up Payment (or a portion thereof)
will be paid which should not have been paid (an "Overpayment") or a Gross-Up
Payment (or a portion thereof) which should have been paid will not have been
paid (an "Underpayment").  An Underpayment shall be deemed to have occurred upon
notice (formal or informal) to the Executive from any governmental taxing
authority that the tax liability of the Executive (whether in respect of the
then current taxable year of the Executive or in respect of any prior taxable
year of the Executive) may be increased by reason of the imposition of the
Excise Tax on a Payment or Payments with respect to which the Company has failed
to make a sufficient Gross-Up Payment.  An Overpayment shall be deemed to have
occurred upon a "Final Determination" (as hereinafter defined) that the Excise
Tax should not be imposed upon a Payment or Payments with respect to which the
Executive has previously received a Gross-Up Payment.  A Final Determination
shall be deemed to have occurred when the Executive has received from the
applicable governmental taxing authority a refund of taxes or other reduction in
his tax liability by reason of the Overpayment and upon either (i) the date of
determination as made by, or an agreement is entered into with, the governmental

                                       12
<PAGE>
 
taxing authority which finally and conclusively binds that Executive  and such
taxing authority, or in the event that a claim is brought before a court of
competent jurisdiction, the date upon which a final determination has been made
by such court and either all appeals have been taken and finally resolved or the
time for all appeals has expired or (ii) the expiration of the statute of
limitations with respect to the Executive's applicable tax return. If an
Underpayment occurs, the Executive shall promptly notify the Company and the
Company shall pay to the Executive at least five (5) business days prior to the
date on which the applicable governmental taxing authority has requested
payment, an additional Gross-up Payment equal to the amount of the Underpayment
plus any interest and penalties imposed on the Underpayment.  If an Overpayment
occurs, the amount of the Overpayment shall be treated as a loan by the Company
to the Executive and the Executive shall, within ten (10) business days of the
occurrence of such Overpayment, pay to the Company the amount of the Overpayment
plus interest at an annual rate equal to the rate provided for in Section
1274(b)(2)(B) of the Code from the date the Gross-Up Payment (to which the
Overpayment relates) was paid to the Executive.

     (d)  Notwithstanding anything contained in this Agreement to the contrary,
in the event it is determined that an Excise Tax will be imposed on any Payment
or Payments, the Company shall pay to the applicable governmental taxing
authorities as Excise Tax withholding, the amount of the Excise Tax that the
Company has actually withhold from the Payment or Payments.

                            LEGAL FEES AND EXPENSES

     6.1. Retention of Counsel.  It is the intent of the Company that the
          --------------------                                           
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of the Executive's
rights to compensation upon a Termination by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended
to be extended to the Executive hereunder.  Accordingly, if it should appear to
the Executive that the Company has failed to comply with any of its obligations
under this Agreement or in the event that the Company or any other person takes
or threatens to take any 

                                       13
<PAGE>
 
action to declare the Agreement to pay Executive compensation upon a Termination
void or unenforceable, or institutes any litigation or other action or
proceeding designed to deny, or to recover from, the Executive the benefits
provided or intended to be provided to the Executive hereunder, the Company
irrevocably authorizes the Executive from time to time to retain counsel of the
Executive's choice, at the expense of the Company as hereinafter provided, to
advise and represent the Executive in connection with any such interpretation,
enforcement or defense, including without limitation the initiation or defense
of any litigation or other legal action, whether by or against the Company or
any Company director, officer, stockholder, or other person affiliated with the
Company, in any jurisdiction.

     6.2. Waiver of Conflict.  Notwithstanding any existing or prior attorney-
          ------------------                                                 
client relationship between the Company and such counsel, the Company
irrevocably consents to the Executive's entering into an attorney-client
relationship with such counsel, and in that connection the Company and the
Executive agree that a confidential relationship will exist between the
Executive and such counsel.

     6.3. Reimbursement of Expenses of Counsel.  Without regard to whether the
          ------------------------------------                                
Executive prevails in whole or in part, in connection with any of the foregoing,
the Company will pay and be solely financially responsible for any and all
attorneys' and related fees and expenses incurred by the Executive in connection
with any of the matters set forth in this Section 6.


                                   SECTION 7

          ----------------------                                       
Agreement will create any right or duty on the part of the Company or the
Executive to have the Executive remain in the employ of the Company prior to or
following any Change in Control, it being acknowledged and agreed by and between
the Company and the Executive that the Executive's employment with the Company
is and shall continue to be terminable "at will" by either party.

     7.2. Termination Prior to Change in Control.  Any termination 
          --------------------------------------                         

                                       14

by the Company of the employment of the Executive, other than for death or
Cause, or the removal of the Executive from any office or position in the
Company, other than for Cause, following the commencement of any discussion with
a third person that results in a Change in Control within 90 calendar days after
such termination or removal shall be deemed to be a Termination of the
Executive's employment after a Change in Control for purposes of this Agreement.


                                   SECTION 8
                                      TERM

     8.1. Term.  The term of this Agreement shall be deemed to commence and be
          ----

upon the Company or grant rights that may be exercised by Executive after a
Termination, this Agreement shall terminate automatically without further action
by either of the parties hereto upon the death or Disability of Executive or the
termination of Executive's employment with the Company for any reason or no
reason that do not occur in the Severance Period, in accordance with Executive's
status as an employee at will.

                         EXECUTIVE SEVERANCE AGREEMENT
                         -----------------------------



     This Executive Severance Agreement (the "Agreement") is made and entered
into as of this _28_ day of June, 1996, by and between Option Care, Inc., a
Delaware corporation (the "Company") and ___Cathy Bellehumeur_________, an
individual residing in the State of Illinois (the "Executive").

                             W I T N E S S E T H:

     WHEREAS, the Board of Directors of the Company (the "Board"), recognizes
that the possibility of a Change in Control (as hereinafter defined in Section
1.1), exists and that the possibility of or the occurrence of a Change in
Control may result in significant distractions of its key management personnel
because of the uncertainties inherent in such a situation; and

     WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its shareholders that the Company be able to receive
and rely upon Executive's advice without concern that the Executive might be
distracted by the personal uncertainties and risks associated with a Change in
Control; and

     WHEREAS, in order to induce the Executive to remain in the employ of the
Company, particularly in the event of the occurrence of a Change in Control, and
for other good and valuable consideration, the Company and the Executive desire
to enter into this Agreement; and
 
     WHEREAS, the Company and Executive each hereby acknowledge that this
Agreement is not intended to be, and shall not be construed as, an express or
implied contract of employment between the Company and the Executive;

     NOW, THEREFORE, in consideration of the respective agreements of the
parties contained herein, it is agreed as follows:
<PAGE>
 
                                   SECTION 1
     DEFINITIONS

     1.1  Definitions.  In addition to terms which may be defined within
          -----------                                                   
specific Sections of this Agreement, the following terms shall have the
following meanings when used herein with initial capital letters:

     (a)  "AFFILIATE" shall mean, as to a specified Person, another Person that
directly, or indirectly through one or more intermediaries, controls or is
controlled by, or is under common control with, the specified Person, within the
meaning of such terms as used in Rule 405 under the Securities Act of 1933, as
amended, or any successor rule.

     (b)  "BASE SALARY" shall mean the sum of the Executive's current annual
base salary, including, if applicable, any car allowance, club dues or other
payments paid to or on behalf of the Executive by the Company determined, in
each case, using the highest rate in effect up to and including the Termination
Date and whether or not actually paid.

     (c)  "BONUS" means an amount paid to Executive on an annual basis which is
equal to thirty percent (30%) of the Executive's then current Base Salary.

     (d)  "CAUSE" shall mean that a majority of the Company's Board of Directors
(the "Board") shall have determined that the Executive (i) willfully and
continually failed to substantially perform his duties with the Company (other
than a failure resulting from Executive's incapacity due to illness, physical or
mental disability or other incapacity) and such failure continues for a period
of thirty (30) days after the Board has given written notice to Executive
providing a reasonable description of the basis for the determination that
Executive has failed to perform his duties, (ii) has been convicted of a felony,
(iii) engaged in conduct constituting willful malfeasance in connection with his
employment which is materially and demonstrably injurious to the Company and its
subsidiaries taken as a whole.  No act, or failure to act, on Executive's part,
shall be considered "willful" for purposes of (i) or (iii) above unless he has
acted or failed to act with an absence of good faith and without a reasonable
belief that his action or failure to act was in the best interests of the
Company. Notwithstanding anything contained in this Agreement to the contrary,
no failure to perform by Executive after Notice of 
<PAGE>
 
Termination (as herein defined) is given by Executive shall constitute Cause for
purposes of this Agreement. No determination of Cause shall be final until the

Board, contest the basis for termination, and demonstrate that Executive's
continued employment is in the best interests of the Company.

     (e)  "CONSTRUCTIVE TERMINATION FOR GOOD REASON" shall mean a termination of
employment with the Company by the Executive pursuant to the provisions of
Section 2.2.

following occurs:

          (i)    Individuals who, as of the date hereof, constitute the entire
     Board of Directors of the Company ("Incumbent Directors") cease for any
     reason to constitute at least a majority of the Board; provided, however,
     that any individual becoming a director subsequent to the date hereof whose
     election, or nomination for election by the Company's stockholders, was
     approved by a vote of at least a majority of the then Incumbent Directors
     shall be considered as though such individual was an Incumbent Director,
     but excluding, for this purpose any such individual whose initial
     assumption of office occurs as a result of either an actual or threatened
     election contest, as such terms are used in Rule 14a-11 under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act") or other
     actual or threatened solicitation of proxies or consents by or on behalf of
     any Person other than the Board; provided, further, that in the event
     Kapoor (as herein defined) at any time determines to achieve representation
     on the Company's Board of Directors approximately equal to his then
     ownership percentage of the Company's common stock, his implementation of

     arranged by any party as a single plan) of all or substantially all of the

     Transaction") where (1) the stockholders of the Company immediately prior
     to such Acquisition Transaction would not immediately after such
     Acquisition Transaction beneficially own, directly or indirectly, shares or
     other ownership interests representing in the aggregate eighty percent
     (80%) or more of (a) the then outstanding common stock or other equity
     interests of the corporation or other entity surviving or resulting from

     Act), directly or indirectly, of securities of the Company representing in
     the aggregate more than fifty percent (50%) of either (A) the then
     outstanding shares of common stock of the Company ("Common Shares") or (B)

because of illness, physical or mental disability or other incapacity, or (ii)
at such earlier time as Executive submits satisfactory medical evidence that he

limitation, any corporation, partnership, Company, joint venture, association or

     or a substantially equivalent office or position, of or with the Company
     which the Executive held immediately prior to a Change in Control;

     limitation a change in the scope of the business or other activities for
     which the Executive was responsible immediately prior to the Change in
     Control, which has rendered the Executive substantially unable to carry

     of the authorities, powers, functions, responsibilities, or duties attached

     Control, which situation is not remedied within five (5) calendar days
     after written notice to the Company from the Executive of such
     determination;

          (d)  the liquidation, dissolution, merger, consolidation, or
     reorganization of the Company or transfer of all or substantially all of
     its business and/or assets, unless the successor or successors (by
     liquidation, merger, consolidation, reorganization, transfer or otherwise)

     2.3. Executive's Other Rights.  A termination by the Company pursuant to
          ------------------------

                                   SECTION 3
                     RIGHTS AND BENEFITS UPON TERMINATION

     3.1. Termination Payments.  In the event Executive shall become entitled to
          --------------------                                                  
receive the rights and benefits described in this Section as a result of the
termination by the Company under Section 2.1 or a Constructive Termination for
Good Reason under Section 2.2 within the Severance Period (hereinafter
collectively referred to as a "Termination"), the Company agrees to provide or
cause to be provided to Executive the following rights and benefits:

     (a)    The Company shall pay to the Executive in a lump sum, by certified
check, within ten (10) "business days" (which for purposes of this Agreement
shall mean any day other than Saturday, Sunday or public holiday under the laws
of the State of Illinois) after the Termination Date, or, at the election of
Executive, in twelve (12) equal monthly installments, an amount equal to the
aggregate of the following:

          i.   The sum of:

               (i)  The Executive's proportionate amount of the Base Salary
          through the Termination Date, to the extent not theretofore paid; plus

               (ii) Any compensation previously deferred by the Executive
          (together with any accrued interest or earnings 

                                       9
<PAGE>
 
          thereon) and any accrued vacation pay, in each case to the extent not
          theretofore paid.

          ii.  An amount equal to one hundred percent (100%) of the Executive's
     Base Salary.

     (b)    For the balance of the Severance Period, but in no event for less
than one year, the Company will arrange to provide the Executive with all
Employee Benefits substantially similar to those which the Executive was
receiving or entitled to receive immediately prior to the Termination Date,
except that the level of any such Employee Benefits to be provided to the
Executive may be reduced in the event of a corresponding reduction applicable
generally to all recipients of or participants in such Employee Benefits, and
the Severance Period will be considered service with the Company for the purpose
of determining service credits and benefits due and payable to the Executive
under the Company's retirement income, supplemental executive retirement, and
other benefit plans of the Company applicable to the Executive, the Executive's
dependents, or the Executive's beneficiaries immediately prior to the
Termination Date. If and to the extent that any benefit described in the
immediately preceding sentence is not or cannot be paid or provided under any
policy, plan program or arrangement of the Company, then the Company will itself
pay or provide for the payment of such Employee Benefits to the Executive, and,
if applicable, the Executive's dependents and Beneficiaries.

     3.2  Bonus Payment. (a)  In the event (i) a Change of Control shall be
          -------------                                                    
consummated during calendar year 1996, or (ii) a Termination shall occur in 1996
during the Severance Period or in 1997, but prior to payment of the Bonus for
calendar year 1996, then, within thirty (30) days of any such event, the Company
shall pay to Executive one hundred percent (100%) of the Bonus which would
otherwise be payable to Executive for 1996.

     (b)  In the event of a Termination during the Severance Period, but after
January 1, 1997, then, in addition to the payments otherwise payable under
Section 3.1 and 3.2(a), the Executive shall be entitled to a payment equal to
the product of (i) thirty percent (30%) of Executive's Base Salary and (ii) a
fraction, the numerator of which is the number of days completed in 1997 through
the Termination Date, and the denominator of which is 365.

                                  MITIGATION

     4.1  No Duty to Mitigate.  In no event shall the Executive be obligated to
          -------------------                                                  
seek other employment or take any other action by way of mitigation of the
amount payable to the Executive under any of the provisions of this agreement
and such amounts shall not be reduced whether or not the Executive obtains other
employment.


                                   SECTION 5
                              ADDITIONAL PAYMENTS

     In addition to the amounts payable to the Executive pursuant to Section 3,
the Company shall make the following payments to the Executive to the extent
applicable:

     5.1. Excise Tax Payment.
          ------------------ 

     (a)    Notwithstanding anything contained in this Agreement to the
contrary, in the event that any payment or distribution to or for the benefit of
the Executive, whether paid or payable or distributed or distributable pursuant
to the terms of this Agreement or otherwise in connection with, or arising out
of, his employment with the Company (a "Payment" or "Payments"), would be
subject to the excise tax imposed by Section 4999 of the Internal Revenue Code
of 1986, as amended (the "Code"), or any interest or penalties are incurred by
the Executive with respect to such excise tax (such excise tax, together with
any interest and penalties, are collectively referred to as the "Excise Tax"),
then the Executive shall be entitled to receive an additional payment (a "Gross-
Up Payment") in an amount such that after payment by the Executive of all taxes
(including any interest or penalties imposed with respect to such taxes),
including any Excise Tax, imposed upon the Gross-up Payment, the Executive
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Payments.

     (b)    A determination shall be made as to whether and when a Gross-Up
Payment is required pursuant to this Section 5.1(b) and the amount of such Gross
Up Payment, such determination to be made within fifteen (15) business days of
the Termination Date, or such other time as requested by the Company or by the
Executive 

                                       11
<PAGE>
 
(provided the Executive reasonably believes that any of the Payments may be
subject to the Excise Tax). Such determination shall be made by a national
independent accounting firm selected by the Executive (the "Accounting Firm").
All fees, costs and expenses (including, but not limited to, the cost of
retaining experts) of the Accounting Firm shall be borne by the Company and the
Company shall pay such fees, costs and expenses as they become due. The
Accounting Firm shall provide detailed supporting calculations, acceptable to
the Executive, both to the Company and the Executive. The Gross-Up Payment, if
any, as determined pursuant to this Section 5.1 shall be paid by the Company to
the Executive within five (5) business days of the receipt of the Accounting
Firm's determination. If the Accounting Firm determines that no Excise Tax is
payable by the Executive with respect to a Payment or Payments, it shall furnish
the Executive with an unqualified opinion that no Excise Tax will be imposed
with respect to any such Payment or Payments. Any such initial determination by
the Accounting Firm of the Gross-Up Payment shall be binding upon the Company
and the Executive subject to the application of Section 5.1(c).

     (c)    As a result of the uncertainty on the application of Sections 4999
and 280G of the Code, it is possible that a Gross-Up Payment (or a portion
thereof) will be paid which should not have been paid (an "Overpayment") or a
Gross-Up Payment (or a portion thereof) which should have been paid will not
have been paid (an "Underpayment"). An Underpayment shall be deemed to have
occurred upon notice (formal or informal) to the Executive from any governmental
taxing authority that the tax liability of the Executive (whether in respect of
the then current taxable year of the Executive or in respect of any prior
taxable year of the Executive) may be increased by reason of the imposition of
the Excise Tax on a Payment or Payments with respect to which the Company has
failed to make a sufficient Gross-Up Payment. An Overpayment shall be deemed to
have occurred upon a "Final Determination" (as hereinafter defined) that the
Excise Tax should not be imposed upon a Payment or Payments with respect to
which the Executive has previously received a Gross-Up Payment. A Final
Determination shall be deemed to have occurred when the Executive has received
from the applicable governmental taxing authority a refund of taxes or other
reduction in his tax liability by reason of the Overpayment and upon either (i)
the date of determination as made by, or an agreement is entered into with, the
governmental 

                                       12
<PAGE>
 
taxing authority which finally and conclusively binds that Executive and such
taxing authority, or in the event that a claim is brought before a court of
competent jurisdiction, the date upon which a final determination has been made
by such court and either all appeals have been taken and finally resolved or the
time for all appeals has expired or (ii) the expiration of the statute of
limitations with respect to the Executive's applicable tax return. If an
Underpayment occurs, the Executive shall promptly notify the Company and the
Company shall pay to the Executive at least five (5) business days prior to the
date on which the applicable governmental taxing authority has requested
payment, an additional Gross-up Payment equal to the amount of the Underpayment
plus any interest and penalties imposed on the Underpayment. If an Overpayment
occurs, the amount of the Overpayment shall be treated as a loan by the Company
to the Executive and the Executive shall, within ten (10) business days of the
occurrence of such Overpayment, pay to the Company the amount of the Overpayment
plus interest at an annual rate equal to the rate provided for in Section
1274(b)(2)(B) of the Code from the date the Gross-Up Payment (to which the
Overpayment relates) was paid to the Executive.

     (d)    Notwithstanding anything contained in this Agreement to the
contrary, in the event it is determined that an Excise Tax will be imposed on
any Payment or Payments, the Company shall pay to the applicable governmental
taxing authorities as Excise Tax withholding, the amount of the Excise Tax that
the Company has actually withhold from the Payment or Payments.

                            LEGAL FEES AND EXPENSES

     6.1. Retention of Counsel.  It is the intent of the Company that the
          --------------------                                           
Executive not be required to incur legal fees and the related expenses
associated with the interpretation, enforcement or defense of the Executive's
rights to compensation upon a Termination by litigation or otherwise because the
cost and expense thereof would substantially detract from the benefits intended
to be extended to the Executive hereunder. Accordingly, if it should appear to
the Executive that the Company has failed to comply with any of its obligations
under this Agreement or in the event that the Company or any other person takes
or threatens to take any 

                                       13
<PAGE>
 
action to declare the Agreement to pay Executive compensation upon a Termination
void or unenforceable, or institutes any litigation or other action or
proceeding designed to deny, or to recover from, the Executive the benefits
provided or intended to be provided to the Executive hereunder, the Company
irrevocably authorizes the Executive from time to time to retain counsel of the
Executive's choice, at the expense of the Company as hereinafter provided, to
advise and represent the Executive in connection with any such interpretation,
enforcement or defense, including without limitation the initiation or defense
of any litigation or other legal action, whether by or against the Company or
any Company director, officer, stockholder, or other person affiliated with the
Company, in any jurisdiction.

     6.2. Waiver of Conflict.  Notwithstanding any existing or prior attorney-
          ------------------                                                 
client relationship between the Company and such counsel, the Company
irrevocably consents to the Executive's entering into an attorney-client
relationship with such counsel, and in that connection the Company and the
Executive agree that a confidential relationship will exist between the
Executive and such counsel.

     6.3. Reimbursement of Expenses of Counsel.  Without regard to whether the
          ------------------------------------                                
Executive prevails in whole or in part, in connection with any of the foregoing,
the Company will pay and be solely financially responsible for any and all
attorneys' and related fees and expenses incurred by the Executive in connection
with any of the matters set forth in this Section 6.


                                   SECTION 7

          ----------------------                                       
Agreement will create any right or duty on the part of the Company or the
Executive to have the Executive remain in the employ of the Company prior to or
following any Change in Control, it being acknowledged and agreed by and between
the Company and the Executive that the Executive's employment with the Company
is and shall continue to be terminable "at will" by either party.

     7.2. Termination Prior to Change in Control.  Any termination 
          --------------------------------------                         

                                       14
<PAGE>
 
by the Company of the employment of the Executive, other than for death or
Cause, or the removal of the Executive from any office or position in the
Company, other than for Cause, following the commencement of any discussion with
a third person that results in a Change in Control within 90 calendar days after
such termination or removal shall be deemed to be a Termination of the
Executive's employment after a Change in Control for purposes of this Agreement.


                                   SECTION 8
                                     TERM

     8.1. Term.  The term of this Agreement shall be deemed to commence and be
          ----

the parties may agree.

     8.2. Termination for Death, Disability or Outside of the Severance Period.
          --------------------------------------------------------------------  
Except with respect to the provisions of this Agreement that provide for
payments to be made to Executive after a Termination, or that impose obligations
upon the Company or grant rights that may be exercised by Executive after a
Termination, this Agreement shall terminate automatically without further action
by either of the parties hereto upon the death or Disability of Executive or the
termination of Executive's employment with the Company for any reason or no
reason that do not occur in the Severance Period, in accordance with Executive's
status as an employee at will.
