and are the products of all parties. Accordingly, neither this Agreement nor
any other Loan Document shall be construed against any Lender or against the
Lenders' Agent merely because of the involvement of any Lender or the
Lenders' Agent in the preparation of this Agreement or any other Loan
Documents.

2.       LOANS.
2.1               TOTAL FACILITY. Subject to all of the terms and conditions
of this Agreement, the Lenders severally agree to make available a total
credit facility of up to forty million dollars ($40,000,000) (the "TOTAL
FACILITY") for the Borrowers' use from time to time during the term of this
Agreement. The Total Facility shall be comprised of: (a) revolving line of
credit up to the limits of the Availability, consisting of Revolving Loans as
described in SECTION 2.2; and (b) the Term Loans as described in SECTION 2.3.
2.2               REVOLVING LOANS.

(a)                     AMOUNTS. Subject to the satisfaction of the
conditions precedent set forth in SECTION 11.1 and SECTION 11.2, as
applicable, each Lender severally agrees, upon request of the Borrowers'
Agent from time to time, to make revolving loans (the "REVOLVING LOANS") to
the Borrowers in amounts not to exceed (except for the Bank with respect to
Non-Ratable Loans and except for the Lenders' Agent with respect to Lenders'
Agent's Advances) such Lender's Pro Rata Share of the Availability calculated
on a consolidated basis with respect to all Option Care Persons. The Lenders,
however, in their unanimous discretion, may elect, with the consent of the
Borrowers' Agent, to make Revolving Loans in excess of the Availability on
one or more occasions, but if they do so, neither the Lenders' Agent nor the
Lenders shall be deemed thereby to have changed the limits of the
Availability or to be obligated to exceed the limits of the Availability on
any other occasion. If the unpaid balance of the Revolving Loans exceeds the
Availability (with Availability determined for this purpose without
subtracting the unpaid balance of the Revolving Loans) then any Lender may
refuse to make or otherwise restrict Revolving Loans on such terms as such
Lender determines until such excess has been eliminated, subject to the
Lenders' Agent's authority, in its sole discretion, to make Lenders' Agent
Advances. The Lenders' Agent shall charge all Revolving Loans and other
Obligations of an Option Care Person to a loan account of Option Care
maintained with the Lenders' Agent (and all references in this Agreement to
the "loan account" of Option Care shall be references to such account). All
Revolving Loans shall be requested by and advanced to the Borrowers' Agent.
All fees, commissions, costs, expenses, and other charges under or pursuant
to the Loan Documents, and all payments made and out-of-pocket expenses
incurred by any Lender or by the Lenders' Agent pursuant to the Loan
Documents, shall be charged as Revolving Loans to the loan account of Option
Care as of the date due or the date paid or incurred by such Lender or by the
Lenders' Agent, as the case may be.

(b)                     PROCEDURE FOR BORROWING.

                       (i) Each Borrowing of a Revolving Loan shall be made
upon an irrevocable Notice of Borrowing from the Borrowers' Agent to the
Lenders' Agent, which Notice of Borrowing must be received by the Lenders'
Agent not later than (1) 12:00 noon,

                                      29
<PAGE>

Chicago time, three Business Days prior to the requested Funding Date in the
case of LIBOR Rate Loans and (2) 12:00 noon, Chicago time, on the requested
Funding Date in the case of Reference Rate Loans, specifying:

                                             (A) that the requested Loan is a
Revolving Loan;

                                             (B) the amount of such Borrowing
which, in the case of LIBOR Revolving Loans, shall be in an amount not less
than one million dollars ($1,000,000) and in an integral multiple of one
hundred thousand dollars ($100,000) in excess thereof;

                                             (C) the requested Funding Date,
which shall be a Business Day;

                                             (D) whether the Revolving Loans
requested are to be Reference Rate Revolving Loans or LIBOR Revolving Loans
(and if not specified, it shall be deemed a request for a Reference Rate
Revolving Loan); and

                                             (E) the duration of the Interest
Period if the requested Revolving Loans are to be LIBOR Revolving Loans. If
such a Notice of Borrowing fails to specify the duration of the Interest
Period for any Borrowing comprised of LIBOR Revolving Loans, such Interest
Period shall be one month.

                                        (ii) After giving effect to any
Borrowing (whether in respect of Revolving Loans or Term Loans), there may
not be more than five different Interest Periods in effect.

(c)                                     AGENT'S ELECTION.  Promptly after
receipt of a Notice of Borrowing pursuant to SECTION 2.2(b), the Lenders'
Agent shall elect, in its discretion, (i) to have the terms of SECTION 2.2(d)
apply to such requested Borrowing, or (ii) to request the Bank to make a
Non-Ratable Loan pursuant to the terms of SECTION 2.2(e) in the amount of the
requested Borrowing; PROVIDED, HOWEVER, that if the Bank declines in its sole
discretion to make a Non-Ratable Loan pursuant to SECTION 2.2(e), the
Lenders' Agent shall elect to have the terms of SECTION 2.2(d) apply to such
requested Borrowing.

(d)                                     MAKING OF REVOLVING LOANS.  (i) In
the event that the Lenders' Agent shall elect to have the terms of this
SECTION 2.2(d) apply to a requested Borrowing as described in SECTION 2.2(c),
then promptly after receipt of a Notice of Borrowing pursuant to SECTION
2.2(b), the Lenders' Agent shall notify the Lenders by telecopy, telephone or
other similar form of transmission, of the requested Borrowing. Subject to
satisfaction of the conditions set forth in SECTION 11.1 and SECTION 11.2, as
applicable, each Lender shall make the amount of such Lender's Pro Rata Share
of the requested Borrowing available to the Lenders' Agent in immediately
available funds, to such account of the Lenders' Agent as the Lenders' Agent
may designate, not later than 2:00 p.m., Chicago time, on the Funding Date
applicable


                                       30

<PAGE>

thereto. After the Lenders' Agent's receipt of the proceeds of such Revolving
Loans, the Lenders' Agent shall make the proceeds of such Revolving Loans
available to the Borrowers' Agent on the applicable Funding Date by
transferring same day funds equal to the proceeds of such Revolving Loans
received by the Lenders' Agent to the account of the Borrowers' Agent,
designated in writing by the Borrowers' Agent to the Lenders' Agent and
acceptable to the Lenders' Agent; PROVIDED, HOWEVER, that the amount of
Revolving Loans so made on any date shall in no event exceed the Availability
on such date.

                                        (ii) Unless the Lenders' Agent
receives notice from a Lender on or prior to the Closing Date or, with
respect to any Borrowing after the Closing Date, at least one Business Day
prior to the date of such Borrowing, that such Lender shall not make
available as and when required hereunder to the Lenders' Agent the amount of
that Lender's Pro Rata Share of such Borrowing, the Lenders' Agent may assume
that each Lender has made such amount available to the Lenders' Agent in
immediately available funds on the Funding Date and the Lenders' Agent may
(but shall not be so required), in reliance upon such assumption, make
available to the Borrowers' Agent on such date a corresponding amount. If and
to the extent any Lender shall not have made its full amount in respect of a
Revolving Loan available to the Lenders' Agent in immediately available funds
and the Lenders' Agent in such circumstances has made available to the
Borrowers' Agent such amount, that Lender shall on the Business Day following
such Funding Date make such amount available to the Lenders' Agent, together
with interest at the Federal Funds Rate for each day during such period. A
notice by the Lenders' Agent submitted to any Lender with respect to amounts
owing under this subsection shall be conclusive, absent manifest error. If
such amount is so made available, such payment to the Lenders' Agent shall
constitute such Lender's Revolving Loan for all purposes of this Agreement.
If such amount is not made available to the Lenders' Agent on the Business
Day following the Funding Date, the Lenders' Agent shall notify the
Borrowers' Agent of such failure to fund and, upon demand by the Lenders'
Agent, the Borrowers' Agent shall pay such amount to the Lenders' Agent for
the Lenders' Agent's account, together with interest thereon for each day
elapsed since the date of such Borrowing, at a rate per annum equal to the
Interest Rate applicable at the time to the Revolving Loans comprising such
Borrowing. The failure of any Lender to make any Revolving Loan on any
Funding Date shall not relieve any other Lender of any obligation hereunder
to make a Revolving Loan on such Funding Date, but no Lender shall be
responsible for the failure of any other Lender to make the Revolving Loan to
be made by such other Lender on any Funding Date.

(e)                                     MAKING OF NON-RATABLE LOANS.  (i) In
the event the Lenders' Agent shall elect, with the consent of the Bank, to
have the terms of this SECTION 2.2(e) apply to a requested Borrowing as
described in SECTION 2.2(d), the Bank shall make a Revolving Loan in the
amount of such Borrowing (any such Revolving Loan made solely by the Bank
pursuant to this SECTION 2.2(e) being referred to as a "NON-RATABLE LOAN" and
such Revolving Loans being referred to collectively as "NON-RATABLE LOANS")
on the Funding Date applicable thereto by transferring same day funds to an
account of the Borrowers' Agent, designated in writing by the Borrowers'
Agent and acceptable to the Lenders' Agent. Each Non-Ratable Loan shall be


                                       31

<PAGE>

subject to all the terms and conditions applicable to other Revolving Loans
except that all payments thereon shall be payable to the Bank solely for its
own account (and for the account of the holder of any participation interest
with respect to such Revolving Loan). The Lenders' Agent shall not request
the Bank to make any Non-Ratable Loan if (A) the Lenders' Agent shall have
received written notice from any Lender that one or more of the applicable
conditions precedent set forth in SECTION 11.1 or SECTION 11.2, as
applicable, shall not be satisfied on the requested Funding Date for the
applicable Borrowing, or (B) the requested Borrowing would exceed the
Availability on such Funding Date. The Lenders' Agent shall not otherwise be
required to determine whether the applicable conditions precedent set forth
in SECTION 11.1 or SECTION 11.2, as the case may be, have been satisfied or
the requested Borrowing would exceed the Availability on the Funding Date
applicable thereto prior to making, in its sole discretion, any Non-Ratable
Loan.

                                        (ii) The Non-Ratable Loans shall be
secured by the Lenders' Agent's Liens in and to the Collateral, shall
constitute Revolving Loans and Obligations hereunder, and shall bear interest
at the rate applicable to the Revolving Loans from time to time.

(f)                                     LENDERS' AGENT ADVANCES.  (i) Subject
to the limitations set forth in the provisos contained in this SECTION
2.2(f), the Lenders' Agent is hereby authorized by the Option Care Persons
and the Lenders, from time to time in the Lenders' Agent's sole discretion,
(A) after the occurrence of a Default or an Event of Default, or (B) at any
time that any of the other applicable conditions precedent set forth in
SECTION 11.1 or SECTION 11.2, as the case may be, have not been satisfied, to
make Reference Rate Revolving Loans to the Borrowers on behalf of the Lenders
which the Lenders' Agent, in its reasonable business judgment, deems
necessary or desirable (1) to preserve or protect the Collateral, or any
portion thereof, (2) to enhance the likelihood of, or maximize the amount of,
repayment of the Loans and other Obligations, or (3) to pay any other amount
chargeable to any Option Care Person pursuant to the terms of this Agreement,
including costs, fees and expenses as described in SECTION 15.9 (any of the
advances described in this SECTION 2.2(f) being hereinafter referred to as
"LENDERS' AGENT ADVANCES").

                                        (ii) The Lenders' Agent Advances
shall be repayable on demand and secured by the Lenders' Agent's Liens in and
to the Collateral, shall constitute Revolving Loans and Obligations
hereunder, and shall bear interest at the rate applicable to Reference Rate
Revolving Loans from time to time. The Lenders' Agent shall notify each
Lender in writing of each such Lenders' Agent Advance.

(g)                                     SETTLEMENT.  It is agreed that each
Lender's funded portion of the Revolving Loans is intended by the Lenders to
be equal at all times to such Lender's Pro Rata Share of the outstanding
Revolving Loans. Notwithstanding such agreement, the Lenders' Agent, the
Bank, and the other Lenders agree (which agreement shall not be for the
benefit of or enforceable by any Option Care Person) that in order to
facilitate the administration of this Agreement and the other Loan Documents,
settlement among them as to the Revolving Loans,


                                       32

<PAGE>

the Non-Ratable Loans and the Lenders' Agent Advances shall take place on a
periodic basis in accordance with the following provisions:

                                        (i) The Lenders' Agent shall request
settlement ("SETTLEMENT") with the Lenders on at least a weekly basis, or on
a more frequent basis if so determined by the Lenders' Agent, (A) on behalf
of the Bank, with respect to each outstanding Non-Ratable Loan, (B) for
itself, with respect to each Lenders' Agent Advance, and (C) with respect to
collections received, in each case, by notifying the Lenders of such
requested Settlement by telecopy, telephone or other similar form of
transmission, of such requested Settlement, no later than 2:00 p.m. (Chicago
time) on the date of such requested Settlement (the "SETTLEMENT DATE"). Each
Lender (other than the Bank, in the case of Non-Ratable Loans and the
Lenders' Agent in the case of Lenders' Agent Advances) shall make the amount
of such Lender's Pro Rata Share of the outstanding principal amount of the
Non-Ratable Loans and Lenders' Agent Advances with respect to which
Settlement is requested available to the Lenders' Agent, to such account of
the Lenders' Agent as the Lenders' Agent may designate, not later than 3:00
p.m. (Chicago time), on the Settlement Date applicable thereto, which may
occur before or after the occurrence or during the continuation of a Default
or an Event of Default and whether or not the applicable conditions precedent
set forth in SECTION 11.1 or SECTION 11.2, as the case may be, have then been
satisfied. Such amounts made available to the Lenders' Agent shall be applied
against the amounts of the applicable Non-Ratable Loan or Lenders' Agent
Advance and, together with the portion of such Non-Ratable Loan or Lenders'
Agent Advance representing the Bank's Pro Rata Share thereof, shall
constitute Revolving Loans of such Lenders. If any such amount is not made
available to the Lenders' Agent by any Lender on the Settlement Date
applicable thereto, the Lenders' Agent shall (A) on behalf of the Bank, with
respect to each outstanding Non-Ratable Loan, and (B) for itself, with
respect to each Lenders' Agent Advance be entitled to recover such amount on
demand from such Lender together with interest thereon at the Federal Funds
Rate for the first three (3) days from and after the Settlement Date and
thereafter at the Interest Rate then applicable to the Revolving Loans.

                                        (ii) Notwithstanding the foregoing,
not more than one (1) Business Day after demand is made by the Lenders' Agent
(whether before or after the occurrence of a Default or an Event of Default
and regardless of whether the Lenders' Agent has requested a Settlement with
respect to a Non-Ratable Loan or Lenders' Agent Advance), each other Lender
(A) shall irrevocably and unconditionally purchase and receive from the Bank
or the Lenders' Agent, as applicable, without recourse or warranty, an
undivided interest and participation in such Non-Ratable Loan or Lenders'
Agent Advance equal to such Lender's Pro Rata Share of such Non-Ratable Loan
or Lenders' Agent Advance and (B) if Settlement has not previously occurred
with respect to such Non-Ratable Loans or Lenders' Agent Advances, upon
demand by the Bank or the Lenders' Agent, as applicable, shall pay to the
Bank or the Lenders' Agent, as applicable, as the purchase price of such
participation an amount equal to one hundred percent (100%) of such Lender's
Pro Rata Share of such Non-Ratable Loans or Lenders' Agent Advances. If such
amount is not in fact made available to the Lenders' Agent by any Lender, the
Lenders' Agent shall be entitled to recover such amount on demand from such
Lender together


                                       33

<PAGE>

with interest thereon at the Federal Funds Rate for the first three (3) days
from and after such demand and thereafter at the Interest Rate then
applicable to Reference Rate Revolving Loans.

                                        (iii) From and after the date, if
any, on which any Lender purchases an undivided interest and participation in
any Non-Ratable Loan or Lenders' Agent Advance pursuant to clause (ii) above,
the Lenders' Agent shall promptly distribute to such Lender such Lender's Pro
Rata Share of all payments of principal and interest and all proceeds of
Collateral received by the Lenders' Agent in respect of such Non-Ratable Loan
or Lenders' Agent Advance.

                                        (iv) Between Settlement Dates, the
Lenders' Agent, to the extent no Lenders' Agent Advances are outstanding, may
pay over to the Bank any payments received by the Lenders' Agent, which in
accordance with the terms of this Agreement would be applied to the reduction
of the Revolving Loans, for application to the Bank's Revolving Loans
including Non-Ratable Loans. If, as of any Settlement Date, collections
received since the then immediately preceding Settlement Date have been
applied to the Bank's Revolving Loans (other than to Non-Ratable Loans or
Lenders' Agent Advances in which such Lender has not yet funded its purchase
of a participation pursuant to clause (ii) above), as provided for in the
previous sentence, the Bank shall pay to the Lenders' Agent for the account
of the Lenders, to be applied to the outstanding Revolving Loans of such
Lenders, an amount such that each Lender shall, upon receipt of such amount,
have, as of such Settlement Date, its Pro Rata Share of the Revolving Loans.
During the period between Settlement Dates, the Bank with respect to
Non-Ratable Loans, the Lenders' Agent with respect to Lenders' Agent
Advances, and each Lender with respect to the Revolving Loans other than
Non-Ratable Loans and Lenders' Agent Advances, shall be entitled to interest
at the applicable rate or rates payable under this Agreement on the actual
average daily amount of funds employed by the Bank, the Lenders' Agent and
the other Lenders.

(h)                                     NOTATION.  The Lenders' Agent shall
record on its books the principal amount of the Revolving Loans owing to each
Lender, including the Non-Ratable Loans owing to the Bank, and the Lenders'
Agent Advances owing to the Lenders' Agent, from time to time. In addition,
each Lender is authorized, at such Lender's option, to note the date and
amount of each payment or prepayment of principal of such Lender's Revolving
Loans in its books and records, including computer records, such books and
records constituting presumptive evidence, absent manifest error, of the
accuracy of the information contained therein. Failure by any Lender or the
Lenders' Agent to make any such recordation or notation shall not affect the
obligations of any Option Care Person under this Agreement or under any other
Loan Document.

(i)                                     LENDERS' FAILURE TO PERFORM.  All
Revolving Loans (other than Non-Ratable Loans and Lenders' Agent Advances)
shall be made by the Lenders simultaneously and in accordance with their Pro
Rata Shares. It is understood that (i) no Lender shall be responsible for any
failure by any other Lender to perform its obligation to make any Revolving
Loans hereunder, nor shall any Commitment of any Lender be increased or
decreased as a result


                                       34

<PAGE>

of any failure by any other Lender to perform its obligation to make any
Revolving Loans hereunder, (ii) no failure by any Lender to perform its
obligation to make any Revolving Loans hereunder shall excuse any other
Lender from its obligation to make any Revolving Loans hereunder, and (iii)
the obligations of each Lender hereunder shall be several, not joint and
several.

2.3                               TERM LOANS.

(a)                                     AMOUNTS.  Subject to the satisfaction
of the conditions precedent set forth in SECTION 11.1 and SECTION 11.2, as
applicable, each Lender severally agrees to make term loans (any such term
loan being referred to as a "TERM LOAN" and such term loans being referred to
collectively as the "TERM LOANS") to the Borrowers, in an amount equal to
such Lender's Pro Rata Share of the Unused Term Loan Amount.

(b)                                     PROCEDURE FOR BORROWING.

                                        (i) Each Borrowing of a Term Loan
shall be made upon an irrevocable Notice of Borrowing from the Borrowers'
Agent to the Lenders' Agent, which notice must be received by the Lenders'
Agent not later than (1) 12:00 noon, Chicago time, three Business Days prior
to the requested Funding Date in the case of LIBOR Rate Loans and (2) 12:00
noon, Chicago time, on the requested Funding Date in the case of Reference
Rate Loans, specifying:

                                            (A) that the requested Loan is a
Term Loan;

                                            (B) the amount of such Borrowing
which, in the case of LIBOR Term Loans, shall be in an amount not less than
five hundred thousand dollars ($500,000) and in an integral multiple of one
hundred thousand dollars ($100,000) in excess thereof;

                                            (C) the requested Funding Date,
which shall be a Business Day;

                                            (D) whether the Term Loans
requested are to be Reference Rate Term Loans or LIBOR Term Loans (and if not
specified, it shall be deemed a request for a Reference Rate Term Loan); and

                                            (E) the duration of the Interest
Period if the requested Term Loans are to be LIBOR Term Loans. If such a
Notice of Borrowing fails to specify the duration of the Interest Period for
any Borrowing comprised of LIBOR Term Loans, such Interest Period shall be
one month.

                                        (ii) After giving effect to any
Borrowing (whether in respect of Term Loans or Revolving Loans), there may
not be more than five different Interest Periods in effect.


                                       35

<PAGE>

(c) MAKING OF TERM LOANS. (i) Promptly after receipt of a Notice of
Borrowing pursuant to SECTION 2.3(b), the Lenders' Agent shall notify the
Lenders by telecopy, telephone or other similar form of transmission, of the
requested Borrowing. Subject to satisfaction of the conditions precedent set
forth in SECTION 11.1 and SECTION 11.2, as applicable, each Lender shall make
the amount of such Lender's Pro Rata Share of the requested Borrowing
available to the Lenders' Agent in immediately available funds, to such
account of the Lenders' Agent as the Lenders' Agent may designate, not later
than 2:00 p.m., Chicago time, on the Funding Date applicable thereto. After
the Lenders' Agent's receipt of the proceeds of such Term Loans, the Lenders'
Agent shall make the proceeds of such Term Loans available to the Borrowers'
Agent on the applicable Funding Date by transferring same day funds equal to
the proceeds of such Term Loans received by the Lenders' Agent to the account
of the Borrowers' Agent, designated in writing by the Borrowers' Agent to the
Lenders' Agent and acceptable to the Lenders' Agent; PROVIDED, HOWEVER, that
the amount of Term Loans so made on any date shall in no event exceed the
Unused Term Loan Amount on such date.

         (ii) Unless the Lenders' Agent receives notice from a Lender on or
prior to the Closing Date or, with respect to any Borrowing after the Closing
Date, at least one Business Day prior to the date of such Borrowing, that
such Lender shall not make available as and when required hereunder to the
Lenders' Agent the amount of that Lender's Pro Rata Share of such Borrowing,
the Lenders' Agent may assume that each Lender has made such amount available
to the Lenders' Agent in immediately available funds on the Funding Date and
the Lenders' Agent may (but shall not be so required), in reliance upon such
assumption, make available to the Borrowers' Agent on such date a
corresponding amount. If and to the extent any Lender shall not have made its
full amount in respect of a Term Loan available to the Lenders' Agent in
immediately available funds and the Lenders' Agent in such circumstances has
made available to the Borrowers' Agent such amount, that Lender shall on the
Business Day following such Funding Date make such amount available to the
Lenders' Agent, together with interest at the Federal Funds Rate for each day
during such period. A notice by the Lenders' Agent submitted to any Lender
with respect to amounts owing under this subsection shall be conclusive,
absent manifest error. If such amount is so made available, such payment to
the Lenders' Agent shall constitute such Lender's Term Loan for all purposes
of this Agreement. If such amount is not made available to the Lenders' Agent
on the Business Day following the Funding Date, the Lenders' Agent shall
notify the Borrowers' Agent of such failure to fund and, upon demand by the
Lenders' Agent, the Borrowers' Agent shall pay such amount to the Lenders'
Agent for the Lenders' Agent's account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal
to the Interest Rate applicable at the time to the Term Loans comprising such
Borrowing. The failure of any Lender to make any Term Loan on any Funding
Date shall not relieve any other Lender of any obligation hereunder to make a
Term Loan on such Funding Date, but no Lender shall be responsible for the
failure of any other Lender to make the Term Loan to be made by such other
Lender on any Funding Date.


                                      36
<PAGE>

(d) NOTATION. The Lenders' Agent shall record on its books the principal amount
of the Term Loans owing to each Lender, from time to time. In addition, each
Lender is authorized, at such Lender's option, to note the date and amount of
each payment or prepayment of principal of such Lender's Term Loans in its books
and records, including computer records, such books and records constituting
presumptive evidence, absent manifest error, of the accuracy of the information
contained therein. Failure by any Lender or the Lenders' Agent to make any such
recordation or notation shall not affect the obligations of any Option Care
Person under this Agreement or any of the other Loan Documents.

(e) LENDERS' FAILURE TO PERFORM. All Term Loans shall be made by the Lenders
simultaneously and in accordance with their Pro Rata Shares. It is understood
that (i) no Lender shall be responsible for any failure by any other Lender to
perform its obligation to make any Term Loans hereunder, nor shall any
Commitment of any Lender be increased or decreased as a result of any failure by
any other Lender to perform its obligation to make any Term Loans hereunder,
(ii) no failure by any Lender to perform its obligation to make any Term Loans
hereunder shall excuse any other Lender from its obligation to make any Term
Loans hereunder, and (iii) the obligations of each Lender hereunder shall be
several, not joint and several.

2.4 AUTOMATED CLEARING HOUSE TRANSFERS. Each Borrower may request and the
Lenders' Agent may, in its sole and absolute discretion, arrange for such
Borrower to obtain from the Bank ACH Transactions. Each Borrower agrees to
indemnify and hold the Lenders' Agent harmless from any and all obligations now
or hereafter owing by the Lenders' Agent to the Bank arising from or related to
such ACH Transactions pursuant to the indemnity referred to in clause (c) below.
Each Borrower agrees to pay the Bank all amounts owing to the Bank pursuant to
ACH Transactions. In the event any Borrower shall not have paid to the Bank such
amounts, the Lenders' Agent shall pay such amounts to the Bank and such amounts
when paid by the Lenders' Agent shall constitute a Revolving Loan which shall be
deemed to have been requested by the Borrowers' Agent. Each Borrower
acknowledges and agrees that the obtaining of ACH Transactions from the Bank (a)
is in the sole and absolute discretion of the Bank, (b) is subject to all rules
and regulations of the Bank, and (c) is due to the Bank relying on the indemnity
of the Lenders' Agent to the Bank with respect to obligations of such Borrower
to the Bank in connection with the ACH Transactions.

2.5 THE BORROWERS' AGENT.

(a) Each Borrower hereby irrevocably appoints, designates and authorizes Option
Care as the agent and attorney-in-fact of such Borrower (Option Care, in such
capacity for all of the Borrowers, being referred to as the "BORROWERS' AGENT")
to give and receive notices, statements, requests and instructions on such
Borrower's behalf under this Agreement and any other Loan Document and otherwise
communicate on such Borrower's behalf with the Lenders' Agent, and, without
limiting the foregoing, to take such action on such Borrower's behalf under the
provisions of this Agreement and each other Loan Document and to exercise such
powers and perform such duties as are delegated to the Borrowers' Agent by the
terms of this Agreement or any other Loan Document, together with such powers as
are incidental thereto. Option Care hereby accepts such appointment, designation
and authorization.


                                      37
<PAGE>

(b) Without limiting the foregoing, the Lenders' Agent may give notices,
statements, requests and instructions to any Borrower through the Borrowers'
Agent and may accept and act upon any notices, statements, requests and
instructions given by the Borrowers' Agent, and each such notice, statement,
request and instruction shall be binding upon the Borrowers. Notwithstanding
such appointment, designation, and authorization, the Lenders' Agent may also
deal directly with, and give and receive notices, statements, requests and
instructions to and from, any Borrower, provided that the Lenders' Agent shall
promptly give notice of any such communications with any Borrower to the
Borrowers' Agent. Any communications transmitted by the Lenders' Agent to a
Borrower shall be sent to such Borrower in care of Option Care at the address of
Option Care determined in accordance with SECTION 15.10. If conflicting
instructions are received from an Option Care Person and from the Borrowers'
Agent, the notice, statement, request or instruction of the Borrowers' Agent
shall prevail.

(c) The Borrowers' Agent may execute any of its duties under this Agreement or
any other Loan Document by or through any of, but none other than, its Chief
Executive Officer, Chief Financial Officer or Secretary. Notwithstanding the
foregoing, but subject to the conditions specified in the proviso to this
sentence, the Borrowers' Agent may authorize other agents, officers or employees
of the Borrowers' Agent (such other agents, officers or employees being referred
to collectively as the "ADDITIONAL AUTHORIZED INDIVIDUALS" and individually as
an "ADDITIONAL AUTHORIZED INDIVIDUAL") to sign and submit a Notice of Borrowing
or sign and submit a Notice of Conversion/Continuation; provided that no Person
shall be considered to be an Additional Authorized Individual unless the
Lenders' Agent shall have received (i) a written list of such Additional
Authorized Individuals and their respective signatures, and the Lenders' Agent
shall have acknowledged receipt of such list in writing, and (ii) a resolution
of the board of directors of the Borrowers' Agent specifically identifying such
Additional Authorized Individuals or authorizing one or more officers of the
Borrowers' Agent to designate Additional Authorized Individuals, it being
understood and agreed that the list and resolutions described in clauses (i) and
(ii) shall be in form and substance reasonably satisfactory to the Lenders'
Agent and shall be certified by the Secretary of the Borrowers' Agent pursuant
to a certificate which is in form and substance reasonably satisfactory to the
Lenders' Agent.

(d) The Borrowers' Agent shall promptly forward to (i) the Lenders and the
Lender' Agent and (ii) the Borrowers, as appropriate, all notices, documents,
certificates, financial statements and reports received by it in the performance
of its duties hereunder.

(e) The Borrowers' Agent shall perform its duties hereunder and under the other
Loan Documents on behalf of the Borrowers. All actions of the Borrowers' Agent
shall in each case bind all the Borrowers, whether or not any such action has
been duly authorized by such Borrowers.


                                      38

2.6 DEFAULTING LENDER. The Lenders' Agent shall not be obligated to transfer
to a Defaulting Lender any payments made by any Option Care Person to the
Lenders' Agent for the Defaulting Lender's benefit; nor shall a Defaulting
Lender be entitled to the sharing of any payments hereunder. Amounts payable
to a Defaulting Lender shall instead be paid to or retained by the Lenders'
Agent. With respect to payments on Revolving Loans, the Lenders' Agent may
hold and, in its discretion, re-lend to the Borrowers the amount of all such
payments received or retained by it for the account of such Defaulting
Lender. Any amounts so re-lent to the Borrowers shall bear interest at the
rate applicable to Reference Rate Revolving Loans and for all other purposes
of this Agreement shall be treated as if they were Revolving Loans.
Notwithstanding any other part of this Agreement, for purposes of voting or
consenting to matters with respect to the Loan Documents and determining Pro
Rata Shares, a Defaulting Lender shall be deemed not to be a "Lender". Until
a Defaulting Lender cures its failure to fund its Pro Rata Share of any
Borrowing (A) such Defaulting Lender shall not be entitled to any portion of
the Unused Line Fee and (B) the Unused Line Fee shall accrue in favor of the
Lenders which have funded their respective Pro Rata Shares of the applicable
requested Borrowing and shall be allocated among such performing Lenders
ratably based upon their relative Commitments. This Section shall remain
effective with respect to such Lender until such time as the Defaulting
Lender shall no longer be in default of any of its obligations under this
Agreement. The terms of this Section shall not be construed to increase or
otherwise affect the Commitment of any Lender, or relieve or excuse the
performance by any Option Care Person of its duties and obligations hereunder.

3.       INTEREST AND OTHER CHARGES.

3.1 INTEREST.

(a) All Obligations shall bear interest on the unpaid principal amount thereof
from the date made until paid in full in cash at a rate determined by reference
to the Reference Rate or the LIBOR Rate and SECTIONS 3.1(a)(i), (ii), (iii) or
(iv), as applicable, but not to exceed the Maximum Rate. Subject to the
provisions of SECTION 3.2, any of the Loans may be converted into, or continued
as, Reference Rate Loans or LIBOR Rate Loans in the manner provided in SECTION
3.2. If at any time Loans are outstanding with respect to which notice has not
been delivered to the Lenders' Agent in accordance with the terms of this
Agreement specifying the basis for determining the interest rate applicable
thereto, then those Loans shall be Reference Rate Loans and shall bear interest
at a rate determined by reference to the Reference Rate until notice to the
contrary has been given to the Lenders' Agent in accordance with this Agreement
and such notice has become effective. Except as otherwise provided herein, the
Obligations shall bear interest as follows:

                                    (i) For all Obligations (other than LIBOR
Revolving Loans, LIBOR Term Loans and Reference Rate Term Loans), at a
fluctuating per annum rate equal to the Reference Rate;

                                    (ii) For all LIBOR Revolving Loans, at a
per annum rate equal to the LIBOR Rate determined for the applicable Interest
Period PLUS two and one-eighth percent (2.125%);

                                      39
<PAGE>

                                    (iii) For all LIBOR Term Loans, at a per
annum rate equal to the LIBOR Rate determined for the applicable Interest
Period PLUS the Applicable LIBOR Term Loan Margin; and

                                    (iv) For all Reference Rate Term Loans,
at a fluctuating per annum rate equal to the Reference Rate PLUS one percent
(1%).

           Each change in the Reference Rate shall be reflected in the interest
rate described in clauses (i) and (iv) above as of the effective date of such
change. All interest charges in respect of the Obligations shall be computed on
the basis of a year of three hundred sixty (360) days and actual days elapsed.
All interest on the Obligations shall be payable to the Lenders on the first day
of each month hereafter, and, with respect to a LIBOR Rate Loan, on the last day
of each Interest Period relating thereto.

(b) If any Event of Default occurs, then, from the date such Event of Default
occurs until it is cured or waived, or if not cured or waived until all
Obligations are paid and performed in full, then the Borrowers shall pay
interest on the unpaid Obligations at a per annum rate two percent (2%) greater
than the rate of interest otherwise specified herein.

(c) UNUSED LINE FEE. For every month during the term of this Agreement, the
Borrowers shall pay the Lenders' Agent, for the account of the Lenders, in
accordance with their Pro Rata Shares, a fee (the "UNUSED LINE FEE") in an
amount equal to one-quarter of one percent (0.25%) per annum, MULTIPLIED BY the
average daily amount by which the Maximum Revolving Credit Line exceeds the
average daily outstanding amount of Revolving Loans during such month, with the
outstanding amount of Revolving Loans calculated for this purpose by applying
payments immediately upon receipt. Such a fee, if any, shall be calculated on
the basis of a year of three hundred sixty (360) days and actual days elapsed,
and shall be payable to the Lenders on the first day of each month and on the
termination of this Agreement, in each case, with respect to the prior month or
portion thereof.

3.2      CONVERSION AND CONTINUATION ELECTIONS.

(a) The Borrowers' Agent may, upon irrevocable written notice to the Lenders and
the Lenders' Agent in accordance with SUBSECTION 3.2(b):

                                    (i) elect, as of any Business Day, in the
         case of Reference Rate Revolving Loans to convert any such Loans (or
         any part thereof) in an amount that is not less than one million
         dollars ($1,000,000), or that is in an integral multiple of one
         hundred thousand dollars ($100,000) in excess thereof, into LIBOR
         Revolving Loans; or

                                    (ii) elect, as of the last day of the
         applicable Interest Period, to continue any LIBOR Revolving Loans
         having Interest Periods expiring on such day (or any part thereof)
         in an amount that is not less than one million dollars ($1,000,000),
         or

                                      40
<PAGE>

         that is in an integral multiple of one hundred thousand dollars
         ($100,000) in excess thereof;

PROVIDED, that if at any time the aggregate amount of LIBOR Revolving Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than two million five hundred thousand dollars
($2,500,000), such LIBOR Revolving Loans shall automatically convert into
Reference Rate Revolving Loans, and on and after such date the right of the
Borrowers' Agent to continue such Loans as, and convert such Loans into, LIBOR
Revolving Loans, as the case may be, shall terminate.

                     The Borrowers' Agent may, upon irrevocable written notice
to the Lenders and the Lenders' Agent in accordance with SUBSECTION 3.2(b):

                                    (i) elect, as of any Business Day, in the
         case of Reference Rate Term Loans to convert any such Loans (or any
         part thereof) (A) during the Term Loan Draw Period, in an amount
         that is not less than five hundred thousand dollars ($500,000) or
         that is an integral multiple of one hundred thousand dollars
         ($100,000) in excess thereof, and (B) after the Term Loan Draw
         Period, in an amount that is not less than one million dollars
         ($1,000,000) or that is an integral multiple of one hundred thousand
         dollars ($100,000) in excess thereof, into LIBOR Term Loans; or

                                    (ii) elect, as of the last day of the
         applicable Interest Period, to continue any LIBOR Term Loans having
         Interest Periods expiring on such day (or any part thereof) (A)
         during the Term Loan Draw Period, in an amount that is not less than
         five hundred thousand dollars ($500,000) or that is an integral
         multiple of one hundred thousand dollars ($100,000) in excess
         thereof, and (B) after the Term Loan Draw Period, in an amount that
         is not less than one million dollars ($1,000,000) or that is an
         integral multiple of one hundred thousand dollars ($100,000) in
         excess thereof;

PROVIDED, that if at any time the aggregate amount of LIBOR Term Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than (A) five hundred thousand dollars ($500,000) during
the Term Loan Draw Period, and (B) one million dollars ($1,000,000) after the
Term Loan Draw Period, such LIBOR Term Loans shall automatically convert into
Reference Rate Term Loans, and on and after such date the right of the
Borrowers' Agent to continue such Loans as, and convert such Loans into, LIBOR
Term Loans, as the case may be, shall terminate.

(b) The Borrowers' Agent shall deliver a written notice of conversion or
continuation ("NOTICE OF CONVERSION/CONTINUATION") to be received by the Lenders
and the Lenders' Agent not later than 12:00 noon, Chicago time, at least three
Business Days in advance of the date of conversion or continuation (the
"CONVERSION/CONTINUATION DATE"), if the Loans are to be converted into or
continued as LIBOR Rate Loans and specifying:


                                      41
<PAGE>


                          (A)      the proposed Conversion/Continuation Date;

                          (B)      the aggregate amount of Loans to be
converted or continued;

                          (C)      the type of Loans resulting from the
proposed conversion or continuation; and

                          (D)      the duration of the requested Interest
Period, PROVIDED, HOWEVER, the Borrowers' Agent may not select an Interest
Period with respect to any portion of the LIBOR Term Loans which extends
beyond an installment payment date for the LIBOR Term Loans unless, after
giving effect to such election, the portion of the LIBOR Term Loans subject
to Interest Periods ending prior to such installment payment date is equal to
or greater than the principal due on such installment payment date.

(c)                       If upon the expiration of any Interest Period
applicable to LIBOR Rate Loans, the Borrowers' Agent has failed to select
timely a new Interest Period to be applicable to LIBOR Rate Loans or if any
Event or Event of Default then exists, the Borrowers' Agent shall be deemed
to have elected to convert such LIBOR Rate Loans into Reference Rate Loans
effective as of the expiration date of such Interest Period.

(d)                       All conversions and continuations shall be made
ratably according to the respective outstanding principal amounts of the
Loans with respect to which the notice was given held by each Lender.

(e)                       During the existence of an Event, the Majority
Lenders shall have the right to decline to permit a Loan to be converted into
or continued as a LIBOR Rate Loan. During the existence of an Event of
Default, the Borrowers' Agent shall not elect to have a Loan converted into
or continued as a LIBOR Rate Loan.

(f)                       After giving effect to any conversion or
continuation of Loans (whether Term Loans or Revolving Loans), there may not
be more than five different Interest Periods in effect.

3.3             MAXIMUM INTEREST RATE. In no event shall any interest rate
provided for hereunder exceed the maximum rate permissible for corporate
borrowers under applicable law for loans of the type provided for hereunder
(the "MAXIMUM RATE"). If, in any month, any interest rate, absent such
limitation, would have exceeded the Maximum Rate, then the interest rate for
that month shall be the Maximum Rate, and, if in future months, that interest
rate would otherwise be less than the Maximum Rate, then that interest rate
shall remain at the Maximum Rate until such time as the amount of interest
paid hereunder equals the amount of interest which would have been paid if
the same had not been limited by the Maximum Rate. In the event that, upon
payment in full of the Obligations, the total amount of interest paid or
accrued under the

                                      42
<PAGE>

terms of this Agreement is less than the total amount of interest which
would, but for this SECTION 3.3, have been paid or accrued if the interest
rates otherwise set forth in this Agreement had at all times been in effect,
then the Borrowers shall, to the extent permitted by applicable law, pay the
Lenders' Agent, for the account of the Lenders, an amount equal to the excess
of (a) the lesser of (i) the amount of interest which would have been charged
if the Maximum Rate had, at all times, been in effect or (ii) the amount of
interest which would have accrued had the interest rates otherwise set forth
in this Agreement, at all times, been in effect over (b) the amount of
interest actually paid or accrued under this Agreement. In the event that a
court determines that the Lenders' Agent or any Lender has received interest
and other charges hereunder in excess of the Maximum Rate, such excess shall
be deemed received on account of, and shall automatically be applied to
reduce, the Obligations other than interest, in the inverse order of
maturity, and if there are no Obligations outstanding, the Lenders' Agent or
such Lender shall refund to the applicable Borrowers such excess.

3.4             FACILITY FEE. The Borrowers shall pay the Lenders' Agent on
the Closing Date, for the account of the Lenders, in accordance with their
respective Pro Rata Shares, a facility fee in the amount of one hundred fifty
thousand hundred dollars ($150,000) (the "FACILITY FEE"), less twenty-five
thousand dollars ($25,000) previously paid as a commitment fee by Option Care
in respect thereof pursuant to the letter dated May 3, 2000 from Banc of
America Commercial Finance Corporation to Option Care.

4.       PAYMENTS AND PREPAYMENTS.

4.1             REVOLVING LOANS. The Borrowers shall repay the outstanding
principal balance of the Revolving Loans, plus all accrued but unpaid
interest thereon, upon the termination of this Agreement for any reason. In
addition, and without limiting the generality of the foregoing, the Borrowers
shall pay to the Lenders' Agent, for the account of the Lenders, on demand,
the amount by which the unpaid principal balance of the Revolving Loans at
any time exceeds the Availability at such time (determined for this purpose
as if the amount of the Revolving Loans were zero) regardless of whether any
Lender elected to make Revolving Loans in excess of the Availability;
provided that if the unpaid principal balance of the Revolving Loans so
exceeds the Availability solely because the Lenders' Agent established Other
Criteria, then the Borrowers shall pay to the Lenders' Agent, within two days
after demand by the Lenders' Agent, the amount of such excess.

          4.1A  TERM LOANS.

(a)                   The Borrowers shall repay the outstanding principal
balance of the Term Loans in equal quarterly installments of principal, based
on a four (4) year amortization schedule. The first installment payment of
principal on the Term Loans shall be due on the first day of the first month
following the month in which the Term Loan Draw Period ends, with further
installment payments being due on the first day of each third month
thereafter, with a final balloon payment of the remaining outstanding
principal of the Term Loans being due on the Stated Termination Date.

(b)                   The Borrowers may prepay the principal of the Term
Loans in whole or in part, at any time and from time to time upon (a) at
least five (5) Business Days' prior

                                      43
<PAGE>

written notice to the Lenders' Agent and the Lenders, and (b) payment of,
with respect to any LIBOR Term Loans to be prepaid prior to the expiration
date of the Interest Period applicable thereto, the amounts described in
SECTION 6.4. All voluntary prepayments of the principal of the Term Loans
shall be accompanied by the payment of all accrued but unpaid interest on the
Term Loans to the date of prepayment. Any voluntary prepayment under this
Section of less than all of the outstanding principal of the Term Loans shall
be applied to the installments of principal of the Term Loans in the inverse
order of maturity. Amounts paid or prepaid in respect of the Term Loans may
not be reborrowed. If the date of any prepayment of a Term Loan occurs on or
prior to the first Anniversary Date, the Borrowers shall pay the Lenders'
Agent, for the account of the Lenders based on their Pro Rata Shares, an
early prepayment fee equal to two percent (2%) of the amount of such
prepayment. If the date of any prepayment of a Term Loan occurs after the
first Anniversary Date, the Borrowers shall pay to the Lenders' Agent, for
the account of the Lenders based on their Pro Rata Shares, an early
prepayment fee equal to one and one-half percent (1.5%) of the amount of such
prepayment.

(c)                   The Borrowers shall repay the entire unpaid principal
balance of the Term Loans, and all accrued but unpaid interest thereon, on
the Stated Termination Date. In connection with any such repayment, if any
LIBOR Term Loans are prepaid prior to the expiration date of the Interest
Period applicable thereto, the Borrowers shall pay to the Lenders the amounts
described in SECTION 6.4.

4.2      PLACE AND FORM OF PAYMENTS; EXTENSION OF TIME.

(a)                   All payments of principal, interest, and other sums due
to any Lender or the Lenders' Agent shall be made in Dollars (without setoff,
recoupment or counterclaim) at such Person's address determined in accordance
with SECTION 15.10 (except for payments to be made to the Lenders' Agent for
the account of the Lenders, which shall be made to the Lenders' Agent at the
Lenders' Agent's address so determined). Except for Proceeds received
directly by the Lenders' Agent, all such payments shall be made in
immediately available funds.

(b)                   Upon the Lenders' Agent's receipt of funds that are
payable to a Lender, the Lenders' Agent shall promptly distribute to such
Lender, pursuant to the applicable wire transfer instructions received from
such Lender in writing, such funds as such Lender may be entitled to receive,
subject to a Settlement delay as provided for in SECTION 2.2(g).

(c)                   Payments applied to Loans in accordance with SECTION
4.3 shall be apportioned ratably among the Lenders (according to the unpaid
principal balance of the Loans to which such payments relate held by each
Lender) and payments of the fees shall, as applicable, be apportioned ratably
among the Lenders.

(d)                   If any payment of principal, interest, or other sum to
be made hereunder becomes due and payable on a day other than a Business Day,
the due date of such

                                      44
<PAGE>

payment shall be extended to the next succeeding Business Day and interest
thereon shall be payable at the applicable interest rate during such
extension.

(e)                   Unless the Lenders' Agent receives notice from the
Borrowers' Agent prior to the date on which any payment is due to the Lenders
that the Borrowers' Agent will not make such payment in full as and when
required, the Lenders' Agent may assume that the Borrowers' Agent has made
such payment in full to the Lenders' Agent on such date in immediately
available funds and the Lenders' Agent may (but shall not be so required), in
reliance upon such assumption, distribute to each Lender on such due date an
amount equal to the amount then due such Lender. If and to the extent the
Borrowers' Agent has not made such payment in full to the Lenders' Agent,
each Lender shall repay to the Lenders' Agent on demand such amount
distributed to such Lender, together with interest thereon at the Federal
Funds Rate for each day from the date such amount is distributed to such
Lender until the date repaid.

4.3               APPLICATION AND REVERSAL OF PAYMENTS. The Lenders' Agent
shall determine in its sole discretion the order and manner in which Proceeds
of Collateral and other payments that the Lenders' Agent receives are applied
to the Loans, interest thereon, and the other Obligations, and each Lender
and each Option Care Person hereby irrevocably waives the right to direct the
application of any such Proceeds or payments. The Lenders' Agent shall have
the continuing and exclusive right to apply and reverse and reapply any and
all such Proceeds and payments to any portion of the Obligations.

4.4               INDEMNITY FOR RETURNED PAYMENTS. IF AFTER RECEIPT OF ANY
PAYMENT WHICH IS APPLIED TO THE PAYMENT OF ALL OR ANY PART OF THE
OBLIGATIONS, ANY LENDER OR THE LENDERS' AGENT IS FOR ANY REASON COMPELLED TO
SURRENDER SUCH PAYMENT TO ANY PERSON BECAUSE SUCH PAYMENT IS INVALIDATED,
DECLARED FRAUDULENT, SET ASIDE, DETERMINED TO BE VOID OR VOIDABLE AS A
PREFERENCE, IMPERMISSIBLE SETOFF, OR A DIVERSION OF TRUST FUNDS, OR FOR ANY
OTHER REASON, THEN: THE OBLIGATIONS OR PART THEREOF INTENDED TO BE SATISFIED
SHALL BE REVIVED AND CONTINUE AND THIS AGREEMENT SHALL CONTINUE IN FULL FORCE
AS IF SUCH PAYMENT HAD NOT BEEN RECEIVED BY ANY LENDER OR THE LENDERS' AGENT
AND EACH OPTION CARE PERSON SHALL BE LIABLE TO PAY TO EACH LENDER AND THE
LENDERS' AGENT AND HEREBY DOES INDEMNIFY EACH LENDER AND THE LENDERS' AGENT
AND HOLD EACH LENDER AND THE LENDERS' AGENT HARMLESS FOR THE AMOUNT OF SUCH
PAYMENT SURRENDERED. The provisions of this SECTION 4.4 shall be and remain
effective notwithstanding any contrary action which may have been taken by
any Lender or the Lenders' Agent in reliance upon such payment, and any such
contrary action so taken shall be without prejudice to the rights of the
Lenders and the Lenders' Agent under this Agreement and shall be deemed to
have been conditioned upon such payment having become final and irrevocable.
The provisions of this SECTION 4.4 shall survive the termination of this
Agreement.

5.        BOOKS AND RECORDS; MONTHLY STATEMENTS. Each Option Care Person
agrees that the books and records of each Lender and the Lenders' Agent
showing the Obligations and the transactions pursuant to this Agreement and
the other Loan Documents shall be admissible in any action or proceeding
arising therefrom, and shall constitute evidence thereof

                                      45
<PAGE>

(absent manifest error), irrespective of whether any Obligation is also
evidenced by a promissory note or other instrument. The Lenders' Agent shall
provide to the Borrowers' Agent a monthly statement of Loans, payments, and
other transactions pursuant to this Agreement. Such statement shall be deemed
correct, accurate, and binding on the Option Care Persons and as an account
stated (except for reversals and reapplications of payments made as provided
in SECTION 4.3 and corrections of errors discovered by the Lenders' Agent),
unless the Borrowers' Agent notifies the Lenders' Agent in writing to the
contrary within sixty (60) days after such statement is given to the
Borrowers' Agent. In the event a timely written notice of objections is given
by the Borrowers' Agent, only the items to which exception is expressly made
shall be considered to be disputed by the Option Care Persons.

6.       TAXES, YIELD PROTECTION AND ILLEGALITY.

6.1              TAXES.
(a)                   Any and all payments by any Option Care Person to each
Lender and to the Lenders' Agent under this Agreement and any other Loan
Document shall be made free and clear of, and without deduction or
withholding for any Taxes. In addition, the Option Care Persons shall pay all
Other Taxes.

(b)                   Each Option Care Person agrees to indemnify and hold
harmless each Lender and the Lenders' Agent for the full amount of Taxes or
Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction
on amounts payable under this Section) paid by any Lender or the Lenders'
Agent and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, whether or not such
Taxes or Other Taxes were correctly or legally asserted. A Lender or the
Lenders' Agent shall make payments of Other Taxes only in the event that
either (i) an Event of Default has occurred; or (ii) in the event that such
Other Taxes remain delinquent for more than thirty (30) days after the
Lenders' Agent has provided notice thereof to the Borrowers' Agent. Payment
under this indemnification shall be made within thirty (30) days after the
date any Lender or the Lenders' Agent makes written demand therefor.

(c)                   If any Option Care Person shall be required by law to
deduct or withhold any Taxes or Other Taxes from or in respect of any sum
payable hereunder to any Lender or the Lenders' Agent, then:

                      (i) the sum payable shall be increased as necessary so
that after making all required deductions and withholdings (including
deductions and withholdings applicable to additional sums payable under this
Section) such Lender or the Lenders' Agent, as the case may be, receives an
amount equal to the sum it would have received had no such deductions or
withholdings been made;

                      (ii) such Option Care Person shall make such deductions
and withholdings;

                      (iii) such Option Care Person shall pay the full amount
deducted or withheld to the relevant taxing authority or other authority in
accordance with applicable law; and

                                      46
<PAGE>

                      (iv) such Option Care Person shall also pay to each
Lender or to the Lenders' Agent for the account of such Lender at the time
interest is paid, all additional amounts which such Lender specifies as
necessary to preserve the after tax yield such Lender would have received if
such Taxes or Other Taxes had not been imposed.

(d)                   Within 60 days after the date of any payment by any
Option Care Person of Taxes or Other Taxes referred to in clause (c) above,
such Option Care Person shall furnish the Lenders' Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment reasonably satisfactory to the Lenders' Agent, which such
satisfactory evidence shall include, without limitation, canceled checks.

6.2              ILLEGALITY.
         (a) If any Lender determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Public Authority has asserted
that it is unlawful, for any Lender or its applicable lending office to make
LIBOR Rate Loans, then, on notice thereof by such Lender to the Borrowers'
Agent and the Lenders' Agent, any obligation of such Lender to make LIBOR
Rate Loans shall be suspended until such Lender notifies the Borrowers' Agent
and the Lenders' Agent that the circumstances giving rise to such
determination no longer exist.

         (b) If any Lender determines that it is unlawful to maintain any
LIBOR Rate Loan, then, upon demand by such Lender to the Borrowers' Agent
(with a copy to the Lenders' Agent), each Borrower shall prepay in full all
of the LIBOR Rate Loans of such Lender relating to such Borrower and then
outstanding, together with interest accrued thereon and amounts required
under SECTION 6.4, either on the last day of the Interest Period thereof, if
such Lender may lawfully continue to maintain such LIBOR Rate Loans to such
day, or immediately, if such Lender may not lawfully continue to maintain
such LIBOR Rate Loans. If any Borrower is required to so prepay any LIBOR
Rate Loan, then concurrently with such prepayment, such Borrower shall borrow
from such Lender, in the amount of such repayment, a Reference Rate Loan.

6.3              INCREASED COSTS AND REDUCTION OF RETURN.
         (a) If any Lender determines that, due to either (i) the
introduction of or any change in the interpretation of any law or regulation
or (ii) the compliance by such Lender with any guideline or request from any
central bank or other Public Authority (whether or not having the force of
law), there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining any LIBOR Rate Loans, then the
Borrowers shall be liable for, and, upon demand by such Lender from time to
time to the Borrowers' Agent (with a copy to the Lenders' Agent), shall pay
to such Lender additional amounts as are sufficient to compensate such Lender
for such increased costs.

         (b) If any Lender shall have determined that (i) the introduction of
any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy
Regulation, (iii) any change in the interpretation or administration of any
Capital Adequacy Regulation by any central bank or other Public Authority
charged with the interpretation or administration thereof, or (iv)

                                      47
<PAGE>

compliance by such Lender or any corporation or other entity controlling such
Lender with any Capital Adequacy Regulation, affects or would affect the amount
of capital, reserves, or special deposits required or expected to be maintained
by such Lender or any corporation or other entity controlling such Lender and
(taking into consideration such Lender's or such corporation's or other
entity's policies with respect to capital adequacy and such Lender's desired
return on capital) determines that the amount of such capital, reserves, or
special deposits is increased as a consequence of its loans, credits or
obligations under this Agreement, then each Borrower shall be liable for, and,
upon demand of such Lender from time to time to the Borrowers' Agent (with a
copy to the Lenders' Agent), shall pay to such Lender, additional amounts
sufficient to compensate such Lender for such increase. Notwithstanding the
foregoing, all such amounts shall be subject to the provisions of SECTION 3.3.

6.4      FUNDING LOSSES. The Borrowers shall reimburse each Lender and hold
each Lender harmless from any loss or expense which such Lender may sustain or
incur as a consequence of:

         (a) the failure of any Borrower to make on a timely basis any payment
of principal of any LIBOR Rate Loan;

         (b) the failure of any Borrower to borrow, continue or convert a Loan
after the Borrowers' Agent has given (or is deemed to have given) a Notice of
Borrowing or a Notice of Conversion/Continuation;

         (c) the prepayment or other payment (including after acceleration
thereof) of any LIBOR Rate Loan on a day that is not the last day of the
relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its LIBOR Rate Loans or from fees payable to
terminate the deposits from which such funds were obtained.

6.5      INABILITY TO DETERMINE RATES. If the Lenders' Agent determines that
for any reason adequate and reasonable means do not exist for determining the
LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR
Rate Loan, or that the LIBOR Rate for any requested Interest Period with
respect to a proposed LIBOR Rate Loan does not adequately and fairly reflect
the cost to the Lenders of funding such Loan, the Lenders' Agent shall so
notify the Borrowers' Agent. Thereafter, the obligation of the Lenders to make
or maintain LIBOR Rate Loans hereunder shall be suspended until the Lenders'
Agent revokes such notice in writing. Upon receipt of such notice, the
Borrowers' Agent may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it. If the Borrowers' Agent does not
revoke such Notice, the Lenders shall make, convert or continue the Loans, as
proposed by the Borrowers' Agent, in the amount specified in the applicable
notice submitted by the Borrowers' Agent, but such Loans shall be made,
converted or continued as Reference Rate Loans instead of LIBOR Rate Loans.

6.6      SURVIVAL. The agreements and obligations of the Option Care Persons in
SECTIONS 6.1 through 6.6 shall survive the payment of all other Obligations.

7.    COLLATERAL.

7.1      GRANT OF SECURITY INTEREST.


                                      48

<PAGE>

(a)      As security for the payment and performance of all of the Obligations,
each Option Care Person hereby grants to the Lenders' Agent, for the benefit of
the Lenders and the Lenders' Agent, a continuing security interest in, lien on,
and assignment of all of such Option Care Person's right, title and interest
in, to and under (but none of such Option Care Person's obligations under) all
of the following, in each case wherever located and whether now owned or
existing or hereafter arising or acquired: (i) all Receivables, Inventory,
Equipment, Contractual Rights, Proprietary Rights, Lockboxes, Blocked Accounts,
Payment Accounts, and Proceeds; (ii) all moneys, securities and other property
and the Proceeds thereof, now or hereafter held or received by, or in transit
to, any Lender or the Lenders' Agent from or for any Option Care Person,
whether for safekeeping, pledge, custody, transmission, collection or
otherwise, including, without limitation, all of the deposit accounts, credits,
and balances of any Option Care Person with any Lender or with the Lenders'
Agent and all claims of any Option Care Person against any Lender or the
Lenders' Agent at any time existing; (iii) all deposit accounts with any
financial institutions (including without limitation Northern) with which any
Option Care Person maintains deposits; (iv) the Loan Documents; (v) all
fixtures; (vi) all capital stock or other equity interests in or issued by any
Subsidiary of any Option Care Person or in or issued by any other Person listed
on a schedule to a Pledge Agreement; (vii) any other Property (including
without limitation all checks, monies and other items on deposit from time to
time in any Lockbox or Blocked Account); and (viii) all books, Records and
other Property relating to or referring to any of the foregoing, including,
without limitation, all books, records, ledger cards, data processing records,
computer software and other property and general intangibles at any time
evidencing or relating to the Receivables, Inventory, Equipment, Contractual
Rights, Proprietary Rights, Proceeds, or other items referred to above (all of
the foregoing, and all other property in which the Lenders' Agent may at any
time be granted a Lien, being herein collectively referred to as the
"COLLATERAL"). The Lenders' Agent shall have all of the rights of a secured
party with respect to the Collateral under the UCC and other applicable laws
(except to the extent, if any, prohibited by applicable law).

(b)      All Obligations shall constitute a single loan secured by the
Collateral. The Lenders' Agent may, in its sole discretion, (i) exchange,
waive, or release any of the Collateral, (ii) after the occurrence of an Event
of Default, apply Collateral and direct the order or manner of sale thereof as
the Lenders' Agent may determine, and (iii) after the occurrence of an Event of
Default, settle, compromise, collect, or otherwise liquidate any Collateral in
any manner, all without affecting the Obligations or the right of the Lenders'
Agent to take any other action with respect to any other Collateral.

7.2      PERFECTION AND PROTECTION OF SECURITY INTEREST. Each Option Care
Person shall, at its expense, perform all steps requested by the Lenders' Agent
at any time and from time to time to perfect, maintain, protect, and enforce
the Security Interest including, without limitation: (a) executing and filing
UCC financing or continuation statements, and amendments thereof, in form and
substance satisfactory to the Lenders' Agent; (b) delivering to the Lenders'
Agent the original certificates of title for motor vehicles with the Security
Interest properly endorsed thereon; (c) delivering to the Lenders' Agent the
originals of all instruments, documents, and chattel paper, and all other
Collateral of which the Lenders' Agent determines it should have physical
possession in order to perfect and protect the Security Interest therein, duly
endorsed or assigned to the Lenders' Agent without restriction; (d) delivering
to the Lenders'


                                      49
<PAGE>

Agent warehouse receipts covering any portion of the Collateral located in
warehouses and for which warehouse receipts are issued; (e) executing and
delivering to the Lenders' Agent a security agreement relating to the
Reversions in form and substance satisfactory to the Lender; (f) delivering to
the Lenders' Agent all letters of credit on which such Option Care Person is
named beneficiary; and (g) taking such other steps as are deemed necessary or
appropriate by the Lenders' Agent to maintain the Security Interest, including,
without limitation, transferring Inventory to warehouses designated by the
Lenders' Agent from time to time (unless prohibited by a federal, state or
local statute or regulation governing the business of such Option Care Person,
in which case the applicable Inventory shall be transferred by such Option Care
Person, after notice with respect thereto by such Option Care Person to the
Lenders' Agent, in compliance with applicable statutes and regulations). To the
extent permitted by applicable law, the Lenders' Agent may file, without any
Option Care Person's signature, one or more financing statements disclosing the
Security Interest. Each Option Care Person agrees that a carbon, photographic,
photostatic, or other reproduction of this Agreement or of a financing
statement is sufficient as a financing statement. If any Collateral is at any
time in the possession or control of any warehouseman, bailee or any of the
agents or processors of any Option Care Person, then such Option Care Person
shall notify the Lenders' Agent thereof and shall notify such Person of the
Security Interest in such Collateral and, upon the request of the Lenders'
Agent, instruct such Person to hold all such Collateral for the account of the
Lenders' Agent subject to the instructions of the Lenders' Agent. If at any
time any Collateral is located on any Premises that are not owned by an Option
Care Person, other than equipment located at a patient's premises, then, at the
request of the Lenders' Agent, each Option Care Person shall use reasonable
efforts to obtain written waivers, in form and substance satisfactory to the
Lenders' Agent, of all present and future Liens to which the owner or lessor or
any mortgagee of such Premises may be entitled to assert against the
Collateral. From time to time, each Option Care Person shall, upon request of
the Lenders' Agent, execute and deliver confirmatory written instruments
pledging to the Lenders' Agent, for the benefit of the Lenders and the Lenders'
Agent, the Collateral, but an Option Care Person's failure to do so shall not
affect or limit the Security Interest or the other rights of the Lenders' Agent
in and to the Collateral. So long as this Agreement is in effect and until all
Obligations have been fully satisfied, the Security Interest shall continue in
full force and effect in all Collateral (whether or not deemed eligible for the
purpose of calculating the Availability or as the basis for any advance, loan,
extension of credit, or other financial accommodation).

         Without limiting the generality of the foregoing: (i) each Borrower
which is not a party to a Pledge Agreement acknowledges the terms of such
Pledge Agreement and agrees to comply with such terms as if it were a party to
such Pledge Agreement; and (ii) each Borrower which is an "Issuer", as defined
in the applicable Pledge Agreement, shall register the pledge effected by such
Pledge Agreement on the books of such Borrower.

7.3      LOCATION OF COLLATERAL. Each Option Care Person represents and
warrants to the Lenders and the Lenders' Agent that as of the Closing Date: (a)
the chief executive office of such Option Care Person is located (and at all
times since February 5, 1998, the chief executive office of such Option Care
Person has been located) at 100 Corporate North, Suite 212, Bannockburn,
Illinois 60015; (b) SCHEDULE 7.3 hereto is a correct and complete list of the
location of the books and records of such Option Care Person, the locations of
the Collateral (other than equipment located at a patient's premises), and the
locations of all of its other places


                                      50
<PAGE>

of business; and (c) SCHEDULE 7.3 correctly identifies any of such facilities
and locations that are not owned by the Option Care Persons and sets forth the
names of the owners and lessors or sub-lessors of such facilities and
locations. Each Option Care Person covenants and agrees that it shall not
maintain any Collateral at any location other than those listed on SCHEDULE
7.3, and, with the exception of equipment located at a patient's premises, it
shall not otherwise change or add to any of such locations, unless it gives the
Lenders' Agent written notice thereof within thirty (30) days after such change
in or addition of location, and executes any and all UCC financing statements
and other documents that the Lenders' Agent requests in connection therewith.

7.4      TITLE TO, LIENS ON, AND SALE AND USE OF COLLATERAL. Each Option Care
Person represents and warrants to, and each Option Care Person covenants with,
the Lenders and the Lenders' Agent that: (a) all Collateral is and shall
continue to be owned by the Option Care Persons free and clear of all Liens
whatsoever, except for the Security Interest and other Permitted Liens; (b) the
Security Interest is not and shall not be subject to any prior Lien; (c) each
Option Care Person shall use, store, and maintain the Collateral with all
reasonable care and shall use the Collateral for lawful purposes only; and (d)
no Option Care Person shall, without the prior written approval of the Lenders,
sell, lease, or dispose of or permit the sale or disposition of the Collateral
or any portion thereof, except for sales of Inventory in the ordinary course of
business and as permitted by SECTION 7.12. The inclusion of Proceeds in the
Collateral shall not be deemed the consent of the Lenders to any sale or other
disposition of the Collateral except as expressly permitted herein.

7.5      [Reserved].

7.6      ACCESS AND EXAMINATION. The Lenders' Agent, accompanied by any Lender
which so elects, may at all reasonable times and from time to time (not to
exceed four times each year, absent a continuing Event of Default) have access
to, examine, audit, make extracts from and inspect the records, files, and
books of account of the Option Care Persons and the Collateral and may discuss
the affairs of the Option Care Persons with the officers and management of the
Option Care Persons, except to the extent prohibited by applicable statutes or
regulations with respect to patients' records. Each Option Care Person shall
deliver to the Lenders' Agent any instrument necessary for the Lenders' Agent
to obtain records from any service bureau maintaining records for any Option
Care Person. The Lenders' Agent may, and at the direction of the Majority
Lenders shall, at the reasonable expense of the Option Care Persons, make
copies of all of the books and records of the Option Care Persons, or require
the Option Care Persons to deliver such copies to the Lenders' Agent. The
Lenders' Agent may, without expense to the Lenders' Agent or the Lenders, use
such of the personnel, supplies, and Premises of the Option Care Persons as may
be reasonably necessary and appropriate for maintaining or enforcing the
Security Interest. The Lenders' Agent shall have the right, at any time, in
name of the Lenders' Agent or in the name of a nominee of the Lenders' Agent,
to verify the validity, amount or any other matter relating to the Accounts,
Inventory or other Collateral, by mail, telephone, or otherwise.

7.7      INSURANCE. The Option Care Persons shall insure the Collateral against
loss or damage by fire with extended coverage, theft, burglary, pilferage, loss
in transit, and such other hazards as the Lenders' Agent shall specify, in
amounts, under policies and by insurers acceptable to the Lenders' Agent. The
Option Care Persons shall cause the Lenders' Agent to be named in each such
policy as secured party and loss payee or additional insured, in a manner
acceptable to the Lenders' Agent. Each policy of insurance shall contain a
clause or


                                      51
<PAGE>

endorsement requiring the insurer to give not less than thirty (30) days' prior
written notice to the Lenders' Agent in the event of cancellation of the policy
for any reason other than for failure to pay premiums when due, and requiring
the insurer to give not less than ten (10) days' prior written notice to the
Lenders' Agent in the event of cancellation of the policy for failure to pay
premiums when due. Each Option Care Person shall also pay all premiums for such
insurance when due, and shall deliver to the Lenders' Agent certificates of
insurance and, if requested, photocopies of the policies.

         If the Option Care Persons fail to pay such fees or to procure such
insurance or the premiums therefor when due, the Lenders' Agent may (but shall
not be required to) do so and charge the costs thereof to the loan account of
Option Care as a Revolving Loan. The insurance referred to in the preceding
sentence may, but need not, protect the interests of the Option Care Persons.
The coverage purchased by the Lenders' Agent hereunder may not pay any claim
made by any Option Care Person or any claim that is made against any Option
Care Person in connection with the Collateral. The Option Care Persons may
later cancel any insurance purchased by the Lenders' Agent hereunder, but only
after providing the Lenders' Agent with evidence that the Option Care Persons
have obtained insurance as required by this Agreement. If the Lenders' Agent
purchases insurance for the Collateral, each Option Care Person shall be
responsible for the costs of such insurance, including interest and any other
charges that the Lenders' Agent may impose in connection with the placement of
such insurance, until the effective date of the cancellation or expiration of
such insurance. The costs of the insurance may be added to the total
outstanding Obligations. The costs of the insurance obtained by the Lenders'
Agent hereunder may be more than the cost of insurance that the Option Care
Persons may be able to obtain on their own.

         Each Option Care Person shall promptly notify the Lenders of each
instance of any loss, damage, or destruction to the Collateral in excess of one
hundred thousand dollars ($100,000) or arising from its use, whether or not
covered by insurance. The Option Care Persons shall apply all insurance
proceeds contemplated by this SECTION 7.7 to the reduction of the Obligations;
provided that, prior to the occurrence of an Event of Default, an Option Care
Person may use such proceeds, or any part thereof, to replace, repair, restore
or rebuild the Collateral in a diligent and expeditious manner with materials
and workmanship of substantially the same quality as existed before the loss,
damage or destruction. Following the occurrence and during the continuance of
an Event of Default, the Lenders' Agent shall have the right but not the
obligation to collect all insurance proceeds directly (other than proceeds of
insurance which the Lenders' Agent procured pursuant to this SECTION 7.7, which
may be collected directly by the Lenders' Agent regardless of whether an Event
of Default exists); provided that any insurance proceeds that the Lenders'
Agent collects pursuant to this SECTION 7.7 shall be applied in accordance with
SECTION 4.3.

7.8      COLLATERAL REPORTING. The Borrowers' Agent shall provide the Lenders'
Agent with the following documents and information at the following times in
form satisfactory to the Lenders' Agent: (a) on a monthly basis, a schedule of
cash received; (b) upon request by the Lenders' Agent, copies of invoices, EOBs
(and any similar correspondence from any Account Debtor which is or which at
any time has been an Account Debtor of an Eligible Account), credit memos, and
shipping and delivery documents no later than ten Business Days following such
written request (except to the extent that delivery of the foregoing violates


                                      52
<PAGE>

applicable law); (c) monthly agings and reconciliations of accounts receivable
to be delivered no later than the twentieth day of each month respecting the
immediately preceding month (including detail as to applications of collections
thereon); (d) upon request by the Lenders' Agent, monthly reports as to
"dilutions", including as to the Dilution Percentage for each month and each
calendar quarter, not later than the twentieth day of each month respecting the
immediately preceding month and calendar quarter; (e) upon request by the
Lenders' Agent, monthly reports pertaining to the cash collections in respect
of Accounts as to which more than 120 days have elapsed since Invoice Date, not
later than the twentieth day of each month respecting the immediately preceding
month; (f)(x) during the third week of each month, a Mid-Month Borrowing Base
Certificate for such month, and (y) on the twentieth day of each month (or, if
such day is not a Business Day, on the next Business Day), a Final Borrowing
Base Certificate with respect to the immediately preceding month; (g) monthly
reports of the Inventory balance (by location), to be delivered no later than
the twentieth day of each month respecting the immediately preceding month; (h)
upon reasonable request by the Lenders' Agent, monthly detailed inventory
reports; (i) upon request by the Lenders' Agent, copies of purchase orders,
invoices, and delivery documents for Inventory and Equipment acquired by any
Borrower; (j) such other reports as to the Collateral (including without
limitation reports as to adjusting entries) as the Lenders' Agent shall request
from time to time; and (k) certificates of an officer of the Borrowers' Agent
certifying as to the foregoing; provided that reports delivered pursuant to
clause (c) or clause (e), and the Final Borrowing Base Certificate delivered
pursuant to clause (f), during January of each year may be delivered up to five
Business Days later than the applicable day specified in such clauses.

         If (x) an Event of Default has occurred, or (y) as of the end of any
two consecutive calendar quarters the Dilution Percentage (defined below) for
the twelve month period ending as of the end of each such calendar quarter
exceeds seven and one-half percent (7.5%), then, upon request from the Lenders'
Agent, the Lenders' Agent shall have the right to retain the services of a
collateral monitoring company (at the expense of the Option Care Persons) to
review, monitor and report on Accounts and collections in such manner as may be
required by the Lenders' Agent from time to time. If any of the records or
reports of the Option Care Persons with respect to the Collateral are prepared
by an accounting service or other agent, each Option Care Person hereby
authorizes such service or agent to deliver such records, reports, and related
documents to the Lenders.

         As used herein, "DILUTION PERCENTAGE" means, on any date of
determination, the percentage identified as such in the most recent monthly
report as to "dilutions" referred to in clause (d) of the first paragraph of
this SECTION 7.8 provided by the Borrowers' Agent to the Lenders on or prior to
such date of determination. The Dilution Percentage for any period shall be
calculated as a fraction, the numerator of which is the aggregate amount of
non-cash credits (i.e., reductions) to the accounts receivable of the Option
Care Persons during such period and the denominator of which is the gross
revenues of the Option Care Persons during such period. The Borrowers' Agent
shall not change the method by which it calculates the Dilution Percentage (or
by which it calculates any component thereof) without the prior written consent
of the Lenders.

<PAGE>

(a)                Each Option Care Person hereby represents and warrants to
the Lenders and the Lenders' Agent and covenants with the Lenders and the
Lenders' Agent that: (i) each existing Account represents, and each future
Account shall represent, a BONA FIDE sale or lease and delivery of goods by
an Option Care Person, or rendition of services by an Option Care Person, in
the ordinary course of business of an Option Care Person; (ii) each existing
Account is, and each future Account shall be, at the time any such Account
arose and at the time any such Account is billed, for a liquidated amount
payable by the Account Debtor thereon on the terms set forth in the invoice
therefor or in the schedule thereof delivered to the Lenders, without offset,
deduction, defense, or counterclaim, other than discounts required by law or
contract, and corrections of billing errors, in the ordinary course of
business of an Option Care Person; (iii) no payment shall be received with
respect to any Account, and no credit, discount, extension, or agreement
therefor shall be granted on any Account, except as reported to the Lenders
and the Lenders' Agent in accordance with this Agreement; (iv) each copy of
an invoice or claim form delivered to any Lender or the Lenders' Agent by an
Option Care Person shall be a genuine copy of the original invoice or claim
form sent to the Account Debtor named therein; (v) all goods described in any
invoice or claim form representing a sale of goods shall have been delivered
to the applicable patient and all services of any Option Care Person
described in any invoice or claim form shall have been performed; (vi) each
of the Accounts and the related contracts is in full force and effect and
represents and constitutes a legal, valid and binding obligation of the
related Account Debtor, enforceable against such Account Debtor in accordance
with its terms; (vii) promptly following notice from an Account Debtor as to
an earlier overpayment by such Account Debtor to any Option Care Person, such
Option Care Person has made all payments to such Account Debtor which are
necessary to prevent such Account Debtor from offsetting such overpayment
against any amount which such Account Debtor owes on the Accounts (however,
each Lender acknowledges that notwithstanding said payments, offsets may and
do nonetheless occur); (viii) no direction of any Option Care Person or any
other Person is in effect directing Account Debtors (A) to remit payments in
respect of the Accounts other than to a Lockbox or a Blocked Account or (B)
to remit EOBs in respect of the Accounts to any Person or address other than
to an Option Care Person at its chief executive office; and (ix) during the
one year prior to the Closing Date, no Option Care Person has been subject to
any Government Offset involving in excess of fifty thousand dollars
($50,000). As of the date of each Borrowing, each Option Care Person is
unaware of any potential Government Offset involving in excess of fifty
thousand dollars ($50,000) for any single Governmental Offset and in excess
of two hundred thousand dollars ($200,000) for all such Government Offsets
that has not been disclosed by such Option Care Person to the Lenders in
writing prior to that date. All of the Medicaid and Medicare reports required
to be filed by any Option Care Person for all reporting periods have been
filed with the applicable Government Account Debtor, or HCFA designated
agents or agents of such Government Account Debtor. At all times on and after
the thirtieth day following the Closing Date, each Option Care Person hereby
represents and warrants to the Lenders and the Lenders' Agent that Account
Debtor Notices, signed by the Borrowers, have been delivered to all of the
Account Debtors of the type referred to in clause (p) of the definition of
Eligible Account.

(b)                No Option Care Person shall re-date any invoice, claim
form or sale or make sales on extended dating or extend or modify any Account
(other than to correct billing errors in the ordinary course of business).
Each Lender acknowledges that if an Account Debtor which is the "primary"
payor does not pay a claim in full or denies such claim, an Option


                                       54
<PAGE>

Care Person may send a separate invoice to an Account Debtor which is a
"secondary" payor. If any Option Care Person becomes aware of any matter that
is reasonably likely to materially adversely affect any Account Debtor (other
than a Self-Pay Account Debtor), including information regarding the Account
Debtor's creditworthiness, such Option Care Person shall promptly so advise
the Lenders' Agent.

(c)                No Option Care Person shall accept any note, warrant or
other instrument (except a check or other instrument for the immediate
payment of money, subject to compliance with SECTION 7.10) with respect to
any Account (other than a Self-Pay Account) without the written consent of
the Lenders' Agent. If the Lenders' Agent consents to the acceptance of any
such note, warrant or other instrument, it shall be considered as evidence of
the Account and not payment thereof, and the Option Care Persons shall
promptly deliver such note, warrant or instrument to the Lenders' Agent
appropriately endorsed. Regardless of the form of presentment, demand, notice
of dishonor, protest, and notice of protest with respect thereto, the Option
Care Persons shall remain liable thereon until such note, warrant or
instrument is paid in full. Notwithstanding the foregoing, any Option Care
Person may accept a note (i) from a franchisee or (ii) as payment solely for
the provision of computer software, provided that such Option Care Person
shall (i) promptly notify the Lenders' Agent that it has accepted any such
note, and (ii) upon request by the Lenders' Agent, promptly deliver such note
to the Lenders' Agent appropriately endorsed.

(d)                Each Option Care Person shall notify the Lenders promptly
of (i) all disputes and claims (other than as to discounts required by law or
contract, and corrections of billing errors, in the ordinary course of
business) with Persons which are Account Debtors, involving in excess of
fifty thousand dollars ($50,000) for any single dispute or claim and in
excess of two hundred thousand dollars ($200,000) for all such disputes and
claims, whether any such Person is acting in its capacity as an Account
Debtor or in its individual capacity (e.g., as a landlord or supplier of an
Option Care Person); and (ii) all alleged or asserted Government Offsets
involving in excess of fifty thousand dollars ($50,000) for any single
Government Offset and in excess of two hundred thousand dollars ($200,000)
for all such Government Offsets. No discount, credit or allowance shall be
granted with respect to any Eligible Account to any Account Debtor (other
than in respect of Self-Pay Accounts) without the consent of the Majority
Lenders, which consent shall not be unreasonably withheld, except for: (i)
discounts required by law or contract, and corrections of billing errors, in
the ordinary course of business; and (ii) any other discount which does not
exceed fifty thousand dollars ($50,000), provided that the aggregate amount
of discounts permitted pursuant to this clause (ii) during any calendar year
shall not exceed five hundred thousand dollars ($500,000). The Lenders' Agent
may at all times following the occurrence and during the continuance of an
Event of Default hereunder settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which the Lenders' Agent considers
reasonable and, in all cases, the Lenders' Agent shall credit the loan
account of Option Care with only the net amounts received by the Lenders'
Agent in payment of any Accounts.

(e)                If an Account Debtor returns any Inventory to any Option
Care Person when no Event of Default exists, then such Option Care Person
shall promptly determine the reason for such return and shall issue a credit
memorandum to the Account Debtor in the


                                       55
<PAGE>

appropriate amount. Each Option Care Person shall immediately report to the
Lenders any return involving an amount in excess of fifty thousand dollars
($50,000). Each such report shall indicate the reasons for the returns and
the locations and condition of the returned Inventory. In the event any
Account Debtor returns Inventory to any Option Care Person when an Event of
Default exists, such Option Care Person shall: (i) hold the returned
Inventory in trust for the Lenders' Agent; (ii) segregate all returned
Inventory from all of its other Property; (iii) dispose of the returned
Inventory solely according to the written instructions of the Lenders' Agent;
and (iv) not issue any credits or allowances with respect thereto without the
prior written consent of the Majority Lenders. All returned Inventory shall
remain subject to the Security Interest. Whenever any Inventory is returned
for which an Account had been created, such related Account shall be deemed
ineligible to the extent of such returned Inventory, and Availability shall
be adjusted accordingly.

7.10     COLLECTION OF ACCOUNTS; PAYMENTS.
(a)                Each Option Care Person shall (and all invoices and claim
forms with respect to the Accounts shall) instruct all Account Debtors to
make all payments only to a Lockbox or a Blocked Account (each Lender
acknowledges that payments by patients made at the time that a patient is
receiving goods and services at a facility of an Option Care Person would not
be invoiced to such patient). If, notwithstanding such instructions, any
Option Care Person receives any Proceeds of Accounts, it shall receive such
payments as the trustee for the Lenders' Agent, and shall immediately deliver
such payments to the Lenders' Agent in their original form duly endorsed in
blank or deposit them into a Lockbox, Blocked Account or a Payment Account,
as the Lenders' Agent may direct; PROVIDED, HOWEVER, that each Option Care
Person may maintain a separate account with a local financial institution
(each a "LOCAL ACCOUNT") for the deposit of walk-in payments from patients
and walk-in payments for durable medical equipment from customers; provided,
further, that (i) each Option Care Person shall deposit such walk-in payments
in a Local Account not later than the first Business Day after receiving such
walk-in payments, (ii) each Option Care Person shall cause all available
amounts in such Local Accounts to be transferred by wire transfer or
automated clearinghouse transfer to a Blocked Account during the last week of
each month, and (iii) no Option Care Person shall withdraw any funds on
deposit in any Local Account or permit funds on deposit in any Local Account
to be transferred other than in accordance with this sentence (provided that
this clause (iii) shall not prevent the Option Care Persons from writing
checks on a Local Account for the sole purpose of refunding some or all of
such walk-in payments to the Person or Persons who made such walk-in
payments). Except as otherwise provided under applicable law with respect to
Accounts owed by Government Account Debtors, all collections received in any
such Lockbox, Blocked Account or Payment Account or directly by any Option
Care Person or the Lenders' Agent, and all funds in any Lockbox, Blocked
Account or Payment Account or other account to which such collections are
deposited, shall be the sole property of the Lenders' Agent and subject to
the sole control of the Lenders' Agent and shall be applied by the Lenders'
Agent subject to and in accordance with the terms of SECTION 4.3. The
Lenders' Agent or the designee of the Lenders' Agent may, at any time after
the occurrence of an Event of Default, notify Account Debtors that the
Accounts have been assigned to the Lenders' Agent and of the Security
Interest therein, and may collect them directly (except to the extent
prohibited under applicable law with respect to Accounts owed by Government
Account Debtors) and charge the collection costs and expenses to the loan
account of Option Care as a Revolving Loan. At the request of


                                       56
<PAGE>

the Lenders' Agent, each Option Care Person shall execute and deliver to the
Lenders' Agent such documents as the Lenders' Agent shall require to grant
the Lenders' Agent access to any post office box, lockbox or bank account in
which collections of Accounts are received or deposited.

(b)                Upon the occurrence of (i) an Event or Event of Default,
or (ii) the Availability at any time (calculated for this purpose without
giving effect to clause (b)(iii) of the definition of Availability) being
less than ten percent (10%) of the Availability at such time (calculated for
this purpose without subtracting the unpaid balance of the Revolving Loans,
and without giving effect to clause (b)(iii) of the definition of
Availability), and upon notice from the Lenders' Agent to the Blocked Account
Bank, in accordance with the Blocked Account Agreement, the Blocked Account
Bank shall remit, by automatic standing wire transfer, on a daily basis, all
available amounts in the Blocked Accounts to or at the direction of the
Lenders' Agent. Such amounts shall be applied in accordance with SECTION 4.3.

(c)                All payments received by the Lenders' Agent on account of
Accounts or other Collateral (including Proceeds) shall be the sole property
of the Lenders' Agent and subject to the sole control of the Lenders' Agent
and shall be applied by the Lenders' Agent subject to and in accordance with
the terms of SECTION 4.3. If such payments are received by the Lenders' Agent
at or prior to 1:00 p.m., Chicago time, on any Business Day, such payments
shall be credited to the loan accounts of the Borrowers (conditional upon
final collection) on such Business Day. If such payments are received by the
Lenders' Agent after 1:00 p.m., Chicago time, on any Business Day, such
payments shall be credited to the loan account of Option Care (conditional
upon final collection) on the next Business Day.

(d)                In the event the Borrowers repay all of the Obligations
upon the termination of this Agreement, other than through the receipt by the
Lenders' Agent of payments on account of Accounts or Proceeds of other
Collateral, such payment shall be credited (conditional upon final
collection) to the loan account of Option Care in accordance with SECTION
7.10(c).

(e)                If sales of Inventory are made or services are rendered
for cash in excess of ten thousand dollars ($10,000) in the aggregate, each
Option Care Person, not later than the first Business Day of the following
week, shall (i) deliver to the Lenders' Agent the original checks, cash, or
other forms of payment which such Option Care Person receives, or (ii)
deposit such forms of payment into a Lockbox, a Blocked Account, a Payment
Account or a Local Account, as the Lenders' Agent may direct, in accordance
with the provisions of SECTION 7.10(a).

7.11         INVENTORY. Each Option Care Person represents and warrants to
the Lenders and the Lenders' Agent that all of the Inventory is and shall be
held for sale or lease, or is to be furnished in connection with the
rendition of services in the ordinary course of such Option Care Person's
business, and is and shall be fit for such purposes. Each Option Care Person
shall keep the Inventory in good and marketable condition, at its own
expense. No Option Care Person shall, without prior written notice to the
Lenders, acquire or accept any Inventory on consignment or approval. Each
Option Care Person agrees that all Inventory shall


                                       57
<PAGE>

be produced in accordance with the Federal Fair Labor Standards Act of 1938,
as amended, and all rules, regulations, and orders thereunder. Each Option
Care Person shall maintain an inventory reporting system at all times. Each
Option Care Person shall conduct a physical count of the Inventory at least
once per Fiscal Year, and at such other times as the Lenders' Agent
reasonably requests (provided that unless an Event of Default has occurred
and is continuing, the Lenders' Agent shall not request such a count more
than twice each year), and shall promptly, upon completion, supply the
Lenders' Agent with a copy of such count accompanied by a report of the value
of such Inventory (valued at the lower of cost, on a first-in, first-out
basis, or market value). No Option Care Person shall, without the prior
written consent of the Lenders, sell any Eligible Inventory on a
bill-and-hold, guaranteed sale, sale and return, sale on approval,
consignment, or other repurchase or return basis. Each Option Care Person
further represents and warrants to the Lenders and the Lenders' Agent that
none of the Inventory is or shall be located on real estate which is
designated as `flood prone' or a `flood risk area', as defined by the Flood
Disaster Protection Act of 1973, except for Inventory located in Miami,
Florida. The Option Care Persons represent and warrant to the Lenders and the
Lenders' Agent that the Option Care Persons have obtained, and the Option
Care Persons hereby covenant and agree with the Lenders and the Lenders'
Agent to maintain, flood insurance with respect to all Inventory located in
Miami, Florida, with such flood insurance to be maintained in accordance with
the provisions of SECTION 7.7.

7.12         EQUIPMENT. Each Option Care Person represents and warrants to
the Lenders and the Lenders' Agent that all of the Equipment used or held for
use in the business of an Option Care Person is adequate for its current use,
except that portion of Equipment that is currently under repair. Each Option
Care Person shall keep and maintain such Equipment (or cause such Equipment
to be kept and maintained) in good operating condition and repair (ordinary
wear and tear excepted) and shall make all necessary replacements thereof.

7.13         MATERIAL CONTRACTS. Each Option Care Person shall fully perform
all of its obligations under each of the contracts and agreements to which it
is a party and shall enforce all of its rights and remedies thereunder, in
each case, as it deems appropriate in its business judgment; PROVIDED,
HOWEVER, no Option Care Person shall take any action or fail to take any
action with respect to any such contract or agreement that would cause the
termination of any Material Contract except in the ordinary course of
business of such Option Care Person. As used in this SECTION 7.13, "MATERIAL
CONTRACT" means any contract or agreement to which an Option Care Person is a
party if such contract or agreement involves amounts paid or payable to or by
an Option Care Person in excess of ten thousand dollars ($10,000) during any
calendar year. No Option Care Person shall, without the prior written consent
of the Majority Lenders, modify, amend, supplement, compromise, satisfy,
waive, release, terminate or discharge any Material Contract, the Contractual
Rights relating to any Material Contract, or any collateral securing the
same, except in the ordinary course of business of such Option Care Person.
Each Option Care Person shall notify the Lenders in writing, promptly after
it becomes aware thereof, of any event or fact which could reasonably be
expected to give rise to a claim by it for indemnification under any Material
Contract and shall diligently pursue such right and report to the Lenders on
all further developments with respect thereto, provided that the notification
and reporting requirements set forth in this sentence shall not apply except
to the extent that such a claim for indemnification is made outside of the
ordinary course of business of such Option Care Person. Each Option Care
Person shall remit directly to the Lenders' Agent, for application to the
Obligations in such order as the Lenders' Agent determines, all amounts
received by such Option


                                       58
<PAGE>

Care Person as indemnification or otherwise pursuant to any contract or
agreement relating to Contractual Rights. If an Event of Default exists, then
the Lenders' Agent may directly enforce such right in its own name or in the
name of an Option Care Person and may enter into such settlements or other
agreements with respect thereto as the Lenders' Agent determines. All amounts
thereby recovered by the Lenders' Agent, after deducting the costs and
expenses of the Lenders' Agent in connection therewith, shall be applied to
the Obligations in such order as the Lenders' Agent determines. In any suit,
proceeding or action brought by the Lenders' Agent under any contract or
agreement relating to a Contractual Right for any sum owing thereunder or to
enforce any provision thereof, each Option Care Person shall indemnify and
hold the Lenders and the Lenders' Agent harmless from and against all
expense, loss or damage suffered by reason of any defense, setoff,
counterclaim, recoupment, or reduction of liability whatsoever of the obligor
thereunder arising out of a breach by any Option Care Person of any
obligation thereunder or arising out of any other agreement, indebtedness or
liability at any time owing from any Option Care Person to or in favor of
such obligor or its successors. All such obligations of any Option Care
Person shall be and remain enforceable only against such Option Care Person
and shall not be enforceable against any Lender or the Lenders' Agent.
Notwithstanding any provision hereof to the contrary, each Option Care Person
shall at all times remain liable to observe and perform all of its duties and
obligations under each contract or agreement relating to Contractual Rights
and the exercise of any rights by any Lender or the Lenders' Agent with
respect to the Collateral shall not release any Option Care Person from any
of such duties and obligations. The Lenders and the Lenders' Agent shall not
be obligated to perform or fulfill any of duties or obligations under any
contract or agreement relating to Contractual Rights or to make any payment
thereunder or to make any inquiry as to the nature or sufficiency of any
payment or Property received by any of them thereunder or the sufficiency of
performance by any party thereunder, or to present or file any claim, or to
take any action to collect or enforce any performance or payment of any
amounts due.

7.14         DOCUMENTS, INSTRUMENTS, AND CHATTEL PAPER. Each Option Care
Person represents and warrants to the Lenders and the Lenders' Agent, and
covenants with the Lenders and the Lenders' Agent, that: (a) all documents,
instruments, and chattel paper describing, evidencing, or constituting
Collateral, and all signatures and endorsements thereon, are and shall be
complete, valid, and genuine; and (b) all goods evidenced by such documents,
instruments, and chattel paper are and shall be owned by the Option Care
Person free and clear of all Liens other than Permitted Liens.

7.15         RIGHT TO CURE. The Lenders' Agent may, in its sole discretion,
and shall at the direction of the Majority Lenders, at any time, pay any
amount or do any act required of any Option Care Person hereunder to
preserve, protect, maintain or enforce the Security Interest, which any
Option Care Person fails to pay or do, including, without limitation, payment
of any judgment against any Option Care Person, any insurance premium, any
warehouse charge, any landlord's claim, and any other obligation giving rise
to any Lien upon or with respect to the Collateral. All payments that the
Lenders' Agent makes under this SECTION 7.15 and all out-of-pocket costs and
expenses that the Lenders' Agent pays or incurs in connection with any action
taken by it hereunder shall be charged to the loan account of Option Care as
a Revolving Loan. Any payment made or other action taken by the Lenders'
Agent under this SECTION 7.15 shall be without prejudice to any right to
assert an Event of Default hereunder.

7.16         POWER OF ATTORNEY. Each Option Care Person hereby appoints the
Lenders' Agent and the designees of the Lenders' Agent as such Option Care
Person's attorney,


                                       59
<PAGE>

subject to the provisions of applicable law, with power: (a) to endorse such
Option Care Person's name on any checks, notes, acceptances, money orders, or
other forms of payment or security that come into the possession of any Lender
or the Lenders' Agent; (b) to sign such Option Care Person's name on any
invoice, bill of lading, or other document of title relating to any Collateral,
on drafts against customers, on assignments of Accounts, on notices of
assignment, UCC financing statements and other public records, on verifications
of Accounts and on notices to Account Debtors and to file any such financing
statements by electronic means with or without a signature as authorized or
required by applicable law or filing procedure; (c) to notify the post office
authorities, when an Event of Default exists, to change the address for
delivery of such Option Care Person's mail to an address designated by the
Lenders' Agent and to receive, open and review (but not to dispose of, and in
each instance promptly forward to Option Care) all mail addressed to such
Option Care Person; (d) when an Event of Default exists, to send requests for
verification of Accounts to Account Debtors; and (e) to do all things necessary
to carry out this Agreement; provided that to the extent that applicable law
prohibits the Lenders' Agent from collecting any payment directly from a
Government Account Debtor, the Lenders' Agent shall not collect such payment
directly from such Government Account Debtor. Each Option Care Person ratifies
and approves all acts of such attorney. Neither the Lenders' Agent nor any
other such attorney, as the case may be, shall be liable for any acts or
omissions or for any error of judgment or mistake of fact or law absent gross
negligence or wilful misconduct on the part of the Lenders' Agent or such
attorney, as the case may be. This power, being coupled with an interest, is
irrevocable until this Agreement has been terminated and the Obligations have
been fully satisfied.

7.17     LENDER'S RIGHTS, DUTIES, AND LIABILITIES. Each Option Care Person
assumes all responsibility and liability arising from or relating to the use,
sale, or other disposition of the Collateral. The Obligations shall not be
affected by any failure of any Lender or the Lenders' Agent to take any steps
to perfect the Security Interest or to collect or realize upon the Collateral,
nor shall loss of or damage to the Collateral release any Option Care Person
from any of the Obligations. Following the occurrence of an Event of Default,
the Lenders' Agent may (but shall not be required to), and at the direction of
the Majority Lenders shall, without notice to or consent from any Option Care
Person, sue upon or otherwise collect, extend the time for payment of, modify
or amend the terms of, compromise or settle for cash, credit, or otherwise upon
any terms, grant other indulgences, extensions, renewals, compositions, or
releases, and take or omit to take any other action with respect to the
Collateral, any security therefor, any agreement relating thereto, any
insurance applicable thereto, or any Person liable directly or indirectly in
connection with any of the foregoing, without discharging or otherwise
affecting the liability of any Option Care Person for the Obligations or under
this Agreement or any other agreement now or hereafter existing between any
Lender and any Option Care Person or between the Lenders' Agent and any Option
Care Person; provided that to the extent that applicable law prohibits the
Lenders' Agent from collecting any payment directly from a Government Account
Debtor, the Lenders' Agent shall not collect such payment directly from such
Government Account Debtor.

7.18     [Reserved]

7.19     LICENSE FOR USE OF SOFTWARE AND OTHER INTELLECTUAL PROPERTY. Except to
the extent prohibited by applicable law, each Option Care Person hereby grants
the Lenders' Agent a non-exclusive, royalty-free license (with the right to
sublicense) to use, without payment or royalty of any kind, all books,
documents, EOBs, instruments, files, records, computer software


                                      60
<PAGE>

programs, tapes, disks, data bases, processes and materials used by such Option
Care Person to operate its business (including the collection or other
liquidation of Accounts and other items covered by the definition of
Collateral), which license shall be irrevocable so long as any of the
Obligations remain outstanding or this Agreement is in effect; PROVIDED that
the Lenders' Agent shall not use such license unless an Event of Default
exists; and PROVIDED, FURTHER, that should the consent of any licensor of any
Option Care Person to such grant of the license described herein be required,
each Option Care Person (upon the request of the Lenders' Agent) shall use its
best efforts to obtain the consent of such third-party licensor and, in the
absence of obtaining such consent, shall, upon request of the Lenders' Agent,
download all information required to operate its business (including
information required to collect or otherwise liquidate Collateral) contained in
such licensed computer software programs, tapes, disks, data bases, processes
and materials in a format which is accessible by the Lenders' Agent or
otherwise print out such information.

8.    BOOKS AND RECORDS; FINANCIAL INFORMATION; NOTICES.

8.1      BOOKS AND RECORDS. Each Option Care Person shall maintain, at all
times, correct and complete books, records and accounts in which complete,
correct and timely entries are made of its transactions in accordance with GAAP
consistent with those applied in the preparation of the Financial Statements.
Each Option Care Person shall, by means of appropriate entries, reflect in such
accounts and in all Financial Statements proper liabilities and reserves for
all taxes and proper provision for depreciation and amortization of Property
and bad debts, all in accordance with GAAP. Each Option Care Person shall
maintain at all times books and records pertaining to the Collateral in such
detail, form, and scope as any Lender or the Lenders' Agent shall reasonably
require, including without limitation, records of: (a) all payments received
and all credits and extensions granted with respect to the Accounts; (b) the
return, rejection, repossession, stoppage in transit, loss, damage, or
destruction of any Inventory; and (c) all other dealings affecting the
Collateral which would reasonably be expected to have a Material Adverse Effect.

8.2      FINANCIAL AND OTHER INFORMATION. Each Option Care Person shall
promptly furnish to each Lender or its agents and the Lenders' Agent all such
information as such Lender or the Lenders' Agent shall from time to time
reasonably request through the Borrowers' Agent, and notify its auditors and
accountants that each Lender, its agents and the Lenders' Agent is authorized
by each Option Care Person to obtain such information directly from them.
Without limiting the foregoing, each Option Care Person shall furnish to the
Lenders through the Borrowers' Agent, in such detail as any Lender or the
Lenders' Agent shall request, the following:

(a)        As soon as available, but in any event not later than 105 days after
the close of each Fiscal Year, a copy of Option Care's annual report on Form
10-K filed with the Securities and Exchange Commission or, if Option Care is no
longer required to file an annual report on Form 10-K with the Securities and
Exchange Commission, consolidated and consolidating audited balance sheets, and
statements of operation, and stockholders equity and cash flows for Option Care
and its consolidated Subsidiaries for such Fiscal Year, and the accompanying
notes thereto, setting forth in each case in comparative form figures for the
previous Fiscal Year, all in reasonable detail, fairly presenting the financial
position and the results of operations of Option Care and its consolidated
Subsidiaries as at the date thereof and for the Fiscal Year then ended, and
prepared in accordance with GAAP. Such statements shall be examined in
accordance with generally accepted auditing standards and accompanied by a


                                      61
<PAGE>

report thereon unqualified as to scope by independent certified public

Option Care Person and each ERISA Affiliate have made all required
contributions to any Plan subject to Section 412 of the Code, and no
application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code, except where any failure to contribute

transaction or violation of the fiduciary responsibility rules with respect

Material Adverse Effect.

to occur; (ii) no Pension Plan has any material unfunded liability; (iii) no

to incur, any material liability under Title IV of ERISA with respect to any
Pension Plan (other than premiums due and not delinquent under Section 4007
of ERISA); (iv) no Option Care Person or any ERISA Affiliate has incurred, or
reasonably expects to incur, any material liability (and no event has
occurred which, with the giving of notice under Section 4219 of ERISA, would
result in such liability) under Section 4201 or 4243 of ERISA with respect to
a Multiemployer Plan; and (v) no Option Care Person or any ERISA Affiliate
has engaged in a transaction that could subject any Person to Section 4069 or
4212(c) of ERISA.

any Person acting on its behalf has offered or shall offer the Loans or any

13.   REMEDIES.


                                      81
<PAGE>

(a)        If an Event of Default has occurred and is continuing, the Lenders'
Agent may in its discretion, and shall, at the direction of the Majority
Lenders, without notice to or demand on any Option Care Person, do one or more
of the following at any time or times and in any order: (i) reduce the
Availability or one or more of the elements thereof; (ii) restrict the amount
of or refuse to permit Loans to be made; (iii) terminate this Agreement; (iv)
declare any or all Obligations to be immediately due and payable (PROVIDED,
HOWEVER, that upon the occurrence of any Event of Default described in SECTIONS
12.1(f), 12.1(g), 12.1(h) or 12.1(i), all Obligations shall automatically
become immediately due and payable); and (v) pursue any other rights and
remedies under the Loan Documents and applicable law.

(b)        If an Event of Default has occurred and is continuing: (i) the
Lenders' Agent shall have for the benefit of the Lenders and the Lenders'
Agent, in addition to all other rights of the Lenders and the Lenders' Agent,
the rights and remedies of a secured party under the UCC; (ii) the Lenders'
Agent may, at any time, take possession of the Collateral and keep it on the
Premises of any Option Care Person, at no cost to the Lenders' Agent or the
Lenders, or remove any part of it to such other place or places as the Lenders'
Agent may desire, and each Option Care Person shall, upon the demand of the
Lenders' Agent, at the expense of the Option Care Persons, assemble the
Collateral and make it available to the Lenders' Agent at a place reasonably
convenient to the Lenders' Agent; and (iii) the Lenders' Agent may sell and
deliver any Collateral at public or private sales, for cash, upon credit or
otherwise, at such prices and upon such terms as the Lenders' Agent deems
advisable, in its sole discretion, and may, if the Lenders' Agent deems it
reasonable, postpone or adjourn any sale of the Collateral by an announcement
at the time and place of sale or of such postponed or adjourned sale without
giving a new notice of sale. Without in any way requiring notice to be given in
the following manner, each Option Care Person agrees that any notice by the
Lenders' Agent of sale, disposition or other intended action hereunder or in
connection herewith, whether required by the UCC or otherwise, shall constitute
reasonable notice to such Option Care Person if such notice is mailed by
registered or certified mail, return receipt requested, postage prepaid, or is
delivered personally against receipt, at least five (5) days prior to such
action to the Borrowers' Agent at the address for notices to the Borrowers'
Agent determined in accordance with SECTION 15.10. If any Collateral is sold on
terms other than payment in full at the time of sale, no credit shall be given
against the Obligations until the Lenders' Agent receives payment, and if the
buyer defaults in payment, the Lenders' Agent may resell the Collateral without
further notice to any Option Care Person. In the event the Lenders' Agent seeks
to take possession of all or any portion of the Collateral by judicial process,
each Option Care Person irrevocably waives: (a) the posting of any bond, surety
or security with respect thereto which might otherwise be required; (b) any
demand for possession prior to the commencement of any suit or action to
recover the Collateral; and (c) any requirement that the Lenders or the
Lenders' Agent retain possession and not dispose of any Collateral until after
trial or final judgment. Each Option Care Person agrees that the Lenders and
the Lenders' Agent have no obligation to preserve rights to the Collateral or
marshal any Collateral for the benefit of any Person. The Lenders' Agent is
hereby granted a license or other right to use, without charge, each Option
Care Person's labels, patents, copyrights, name, trade secrets, trade names,
trademarks, and advertising matter, or any similar property, in completing
production of, advertising or selling any Collateral, and each Option Care
Person's rights under all licenses and all franchise agreements shall inure to
the benefit of the Lenders' Agent. The proceeds of sale shall be applied first
to all expenses of sale,


                                      82
<PAGE>

including attorney's fees, and second, in whatever order the Lenders' Agent
elects, to all Obligations. The Lenders' Agent shall return any excess to the
Option Care Persons or such other Person as shall be legally entitled thereto
and the Option Care Persons shall remain liable for any deficiency.

(c)        Each Option Care Person hereby waives (i) all rights to notice and
hearing prior to the exercise by the Lenders' Agent of the rights of the
Lenders' Agent to repossess the Collateral without judicial process following
the occurrence of an Event of Default or to replevy, attach or levy upon the
Collateral without notice or hearing following the occurrence of an Event of
Default, and (ii) all rights of set-off and counterclaim against the Lenders
and the Lenders' Agent.

14.   TERM AND TERMINATION.

(a)        This Agreement shall terminate, without premium or penalty, on
February 5, 2002 (the "STATED TERMINATION DATE") unless earlier terminated as
provided in this Section.

(b)        The Borrowers' Agent may also terminate this Agreement at any time
prior to the Stated Termination Date or during any renewal term if all of the
following conditions have been satisfied: (i) it gives the Lenders' Agent at
least fifteen (15) days' prior written notice of termination; (ii) it pays and
performs (or causes to be paid and performed) all Obligations on or prior to
the effective date of termination; and (iii) it pays the Termination Fee (or
causes the Termination Fee to be paid) to the Lenders' Agent, for the account
of the Lenders, based on their Pro Rata Shares, on or prior to the effective
date of termination, which payment shall be in addition to the fees required by
SECTION 6.4; PROVIDED, HOWEVER, that the Borrowers' Agent shall not be
obligated to pay the Termination Fee if the reason for termination of this
Agreement is that (I) the Bank (or any Affiliate thereof) has provided a
revolving loan facility to the Borrowers which completely refinances the credit
facility provided for in this Agreement; (II) the Lenders' Agent sends a notice
to the Borrowers' Agent establishing Other Criteria; or (III) the Lenders'
Agent sends a notice to the Borrowers' Agent to the effect that the Lenders'
Agent shall maintain a reserve pursuant to clause (E) of the definition of
Availability; PROVIDED, FURTHER, HOWEVER, that notwithstanding clauses (II) and
(III) of the preceding proviso, the Borrowers' Agent shall be required to pay
the Termination Fee (or to cause the Termination Fee to be paid) if either: (x)
the Borrowers' Agent fails to provide written notice to the Lenders' Agent of
its intent to terminate this Agreement within fifteen (15) days after (i) the
Lenders' Agent sends a notice to the Borrowers' Agent establishing Other
Criteria or (ii) the Lenders' Agent sends a notice to the Borrowers' Agent to
the effect that the Lenders' Agent shall maintain a reserve pursuant to clause
(E) of the definition of Availability; or (y) the Borrowers' Agent fails to pay
and perform (or fails to cause to be paid and performed) all Obligations on or
prior to the ninetieth (90th) day following the end of the fifteen (15) day
period referred to in clause (x) of this proviso.

(c)        The Lenders' Agent may, and at the direction of the Majority Lenders
the Lenders' Agent shall, also terminate this Agreement without notice while an
Event of Default exists; provided that no Termination Fee shall be payable
solely as a result of a termination pursuant to this sentence.

                                      83
<PAGE>

(d)              Upon the effective date of termination of this Agreement for
any reason whatsoever, all Obligations shall become immediately due and
payable.

(e)              Notwithstanding the termination of this Agreement, until all
Obligations are paid and performed in full, each of the Lenders' Agent and
the Lenders shall retain all its rights and remedies hereunder (including,
without limitation, in all then existing and after-arising Collateral).

15.    MISCELLANEOUS.

15.1             CUMULATIVE REMEDIES; NO PRIOR RECOURSE TO COLLATERAL. The
enumeration in this Agreement or any other Loan Document of the Lenders'
Agent's rights and remedies is not intended to be exclusive, and such rights
and remedies are in addition to and not by way of limitation of any other
rights or remedies that the Lenders' Agent may have under the UCC or other
applicable law. The Lenders' Agent shall have the right, in its sole
discretion, to determine which rights and remedies are to be exercised and in
which order. The exercise of one right or remedy under or in connection with
this Agreement or any other Loan Document shall not preclude the exercise of
any others, all of which shall be cumulative. The Lenders' Agent may, without
limitation, proceed directly against any Option Care Person to collect the
Obligations without any prior recourse to the Collateral.

15.2             NO IMPLIED WAIVERS. No act, failure or delay by the Lenders'
Agent or any Lender under or in connection with this Agreement or any other
Loan Document shall constitute a waiver of any of its rights and remedies. No
single or partial waiver by the Lenders' Agent or any Lender of any provision
of this Agreement or any other Loan Document, or of breach or default
hereunder or thereunder, or of any right or remedy which the Lenders' Agent
or any Lender may have, shall operate as a waiver of any other provision,
breach, default, right or remedy or of the same provision, breach, default,
right or remedy on a future occasion. No waiver by the Lenders' Agent or any
Lender shall affect its rights to require strict performance of this
Agreement or any other Loan Document.

15.3             SEVERABILITY. Whenever possible, each provision of this
Agreement and each other Loan Document shall be interpreted in such a manner
as to be effective and valid under applicable law, but if any provision of
this Agreement or any other Loan Document shall be prohibited by or invalid
under applicable law, such provision shall be ineffective only to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement or such other Loan
Document.

15.4             GOVERNING LAW. This Agreement and each other Loan Document
shall be deemed to have been made in the State of Illinois and shall be
governed by and interpreted in accordance with the laws of such state, except
that no doctrine of choice of law shall be used to apply the laws of any
other state or jurisdiction.

15.5             CONSENT TO JURISDICTION AND VENUE; SERVICE OF PROCESS. Each
Option Care Person agrees that, in addition to any other courts that may have
jurisdiction under applicable laws, any action or proceeding to enforce or
arising out of this Agreement or any of the other Loan Documents may be
commenced in the courts of the State of Illinois, or in the United States
District Court for the Northern District of Illinois, and each Option Care
Person consents and submits in advance to such jurisdiction and agrees that
venue shall be proper in such courts on any such matter. The choice of forum
set forth in this section shall not be deemed to preclude the enforcement of
any judgment obtained in such forum, or the taking of any action under this


                                      84
<PAGE>

Agreement to enforce the same, in any appropriate jurisdiction. Each Option
Care Person hereby waives personal service of process and agrees that a
summons and complaint commencing an action or proceeding in any such court
shall be properly served and shall confer personal jurisdiction if served by
registered or certified mail to the Borrowers' Agent, at the address for
notices to the Borrowers' Agent determined in accordance with SECTION 15.10.
Should any Option Care Person fail to appear or answer any summons,
complaint, process or papers so served within thirty (30) days after the
mailing or other service thereof, it shall be deemed in default and an order
or judgment may be entered against it as demanded or prayed for in such
summons, complaint, process or papers.

15.6             WAIVER OF JURY TRIAL. EACH OPTION CARE PERSON HEREBY WAIVES
TRIAL BY JURY, RIGHTS OF SETOFF, AND THE RIGHT TO IMPOSE COUNTERCLAIMS IN ANY
LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT
OF THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, THE OBLIGATIONS OR THE
COLLATERAL, OR ANY INSTRUMENT OR DOCUMENT DELIVERED PURSUANT HERETO OR
THERETO, OR ANY OTHER CLAIM OR DISPUTE HOWSOEVER ARISING, BETWEEN OR AMONG
THE OPTION CARE PERSONS, THE LENDERS AND THE LENDERS' AGENT. EACH OPTION CARE
PERSON CONFIRMS THAT THE FOREGOING WAIVERS ARE INFORMED AND FREELY MADE.

15.7             SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All of the
representations and warranties of the Option Care Persons contained in this
Agreement shall survive the execution, delivery, and acceptance thereof by
the parties, notwithstanding any investigation by any Lender or its agents or
the Lenders' Agent or its agents, until the later of (a) the termination of
this Agreement and (b) payment and performance in full of all of the
Obligations.

15.8             OTHER SECURITY AND GUARANTIES. The Lenders' Agent may,
without notice or demand and without affecting the Obligations, from time to
time: (a) take from any Person and hold collateral (other than the
Collateral) for the payment of all or any part of the Obligations and
exchange, enforce or release such collateral or any part thereof; and (b)
accept and hold any endorsement or guaranty of payment of all or any part of
the Obligations and release or substitute any such endorser or guarantor, or
any Person who has given any Lien in any other collateral as security for the
payment of all or any part of the Obligations, or any other Person in any way
obligated to pay all or any part of the Obligations.

15.9             FEES AND EXPENSES. The Option Care Persons agree to pay the
Lenders and the Lenders' Agent on demand (whether or not any transaction
contemplated by this Agreement is consummated) all costs and expenses that
any Lender or the Lenders' Agent pays or incurs in connection with the
negotiation, preparation, consummation, administration, enforcement, and
termination of this Agreement and the other Loan Documents, including,
without limitation: (a) attorneys' and paralegals' fees and disbursements of
counsel to any Lender or the Lenders' Agent (including, without limitation, a
reasonable estimate of the allocable cost of in-house counsel and staff for
non-duplicative work); (b) costs and expenses including attorneys' and
paralegals' fees and disbursements (including, without limitation, a
reasonable estimate of the allocable cost of in-house counsel and staff for
non-duplicative work) for any amendment, supplement, waiver, consent, or
subsequent closing in connection with any Loan Document and the transactions
contemplated thereby; (c) costs and expenses of lien and title searches and
title insurance; (d) Taxes, fees and other charges for filing UCC financing
statements and amendments and continuations thereof, and other actions to
perfect, protect, and


                                      85
<PAGE>

continue the Security Interest; (e) sums paid or incurred to pay any amount
or take any action required of any Option Care Person under the Loan
Documents that such Option Care Person fails to pay or take; (f) costs of
review, due diligence, appraisals, audits, inspections, and verifications of
the Collateral and the operations of any Option Care Person, including,
without limitation, travel, lodging, meals, and other expenses, together with
an allocated "charge" per day for each auditor employed or utilized by the
Lenders' Agent for any such purpose (such "charge" per day to be specified
from time to time by the Lenders' Agent but, absent an Event of Default, the
aggregate "charges" per day during any calendar quarter shall not exceed
$5,000 per calendar quarter, it being understood that said $5,000 cap does
not cover or limit the other costs and expenses referred to in this clause
(f)); (g) costs and expenses of forwarding loan proceeds, collecting checks
and other items of payment, and establishing and maintaining Payment Accounts
and lock boxes; (h) costs and expenses of preserving and protecting the
Collateral (including without limitation costs and expenses relating to
SECTIONS 7.16 and 7.17); and (i) costs and expenses including attorneys' and
paralegals' fees and disbursements (including, without limitation, a
reasonable estimate of the allocable cost of in-house counsel and staff) paid
or incurred to obtain payment of the Obligations, enforce the Security
Interest, sell or otherwise realize upon the Collateral, and otherwise
enforce the provisions of any Loan Document (including without limitation
costs and expenses relating to SECTIONS 7.16 and 7.17), or to defend any
claims made or threatened against any Lender or the Lenders' Agent arising
out of the transactions contemplated by this Agreement or any other Loan
Document (including without limitation, preparations for and consultations
concerning any such matters). The foregoing shall not be construed to limit
any other provisions of the Loan Documents regarding costs and expenses to be
paid by any Option Care Person. All of the foregoing costs and expenses shall
be charged to the loan account of Option Care as Revolving Loans.

15.10            NOTICES. Except as otherwise expressly provided herein or in
an Exhibit hereto, all notices, demands, and requests that any party hereto

15.11            INDEMNIFICATION.

           (a)   EACH OPTION CARE PERSON HEREBY INDEMNIFIES, DEFENDS AND
HOLDS EACH LENDER, THE LENDERS' AGENT, AND THE RESPECTIVE DIRECTORS,
OFFICERS, AGENTS, EMPLOYEES AND COUNSEL OF EACH LENDER AND OF THE LENDERS'
AGENT, HARMLESS FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES,
LIABILITIES, DEFICIENCIES, JUDGMENTS, PENALTIES OR EXPENSES IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST ANY OF THEM, WHETHER DIRECT, INDIRECT OR
CONSEQUENTIAL ARISING OUT OF OR BY REASON OF ANY LITIGATION, INVESTIGATIONS,
CLAIMS, OR PROCEEDINGS (WHETHER BASED


                                      87
<PAGE>

ON ANY FEDERAL, STATE OR LOCAL LAWS OR OTHER STATUTES OR REGULATIONS,
INCLUDING, WITHOUT LIMITATION, SECURITIES, ENVIRONMENTAL, OR COMMERCIAL LAWS
AND REGULATIONS, UNDER COMMON LAW OR AT EQUITY, OR ON CONTRACT OR OTHERWISE)
COMMENCED OR THREATENED, WHICH ARISE OUT OF OR ARE IN ANY WAY BASED UPON THE
NEGOTIATION, PREPARATION, EXECUTION, DELIVERY, ENFORCEMENT, PERFORMANCE OR
ADMINISTRATION OF THIS AGREEMENT, ANY OTHER LOAN DOCUMENT, OR ANY UNDERTAKING
OR PROCEEDING RELATED TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY
ACT, OMISSION TO ACT, EVENT OR TRANSACTION RELATED OR ATTENDANT THERETO,
INCLUDING, WITHOUT LIMITATION, AMOUNTS PAID IN SETTLEMENT, COURT COSTS, AND
THE FEES AND EXPENSES OF COUNSEL INCURRED IN CONNECTION WITH ANY SUCH
LITIGATION, INVESTIGATION, CLAIM OR PROCEEDING AND FURTHER INCLUDING, WITHOUT
LIMITATION, ALL LOSSES, DAMAGES (INCLUDING CONSEQUENTIAL DAMAGES), EXPENSES
OR LIABILITIES SUSTAINED BY ANY LENDER OR THE LENDERS' AGENT IN CONNECTION
WITH ANY ENVIRONMENTAL INSPECTION, MONITORING, SAMPLING, OR CLEANUP OF THE
ENCUMBERED REAL ESTATE REQUIRED OR MANDATED BY ANY ENVIRONMENTAL LAW (ALL OF
THE LOSSES, CLAIMS, DAMAGES, LIABILITIES, DEFICIENCIES, JUDGMENTS, PENALTIES,
FEES, EXPENSES, AMOUNTS PAID IN SETTLEMENT AND COURT COSTS REFERRED TO ABOVE
IN THIS PARAGRAPH (A) BEING REFERRED TO COLLECTIVELY AS THE "INDEMNIFIED
LIABILITIES"); PROVIDED, HOWEVER, THAT THE OPTION CARE PERSONS SHALL NOT
INDEMNIFY A PARTICULAR LENDER, ITS DIRECTORS, OFFICERS, AGENTS, EMPLOYEES AND
COUNSEL FROM SUCH DAMAGES RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH PARTICULAR LENDER, ITS DIRECTORS, OFFICERS, AGENTS,
EMPLOYEES AND COUNSEL.

           (b)   Each Option Care Person hereby indemnifies, defends and
holds harmless the Lender from any loss or liability directly or indirectly
arising out of the use, generation, manufacture, production, storage,
release, threatened release, discharge, disposal or presence of a Hazardous
Substance. This indemnity shall apply whether the Hazardous Substance is on,
under or about any Option Care Person's property or operations or property
leased to any Option Care Person. The indemnity includes but is not limited
to attorneys' fees (including the reasonable estimate of the allocated cost
of in-house counsel and staff). The indemnity extends to the Lender, its
parent, subsidiaries and all of their directors, officers, employees, agents,
successors, attorneys and assigns. "Hazardous Substances" means any
substance, material or waste that is or becomes designated or regulated as
"toxic," "hazardous," "pollutant," or "contaminant" or a similar designation
or regulation under any federal, state or local law (whether under common
law, statute, regulation or otherwise) or judicial or administrative
interpretation of such, including without limitation petroleum or natural gas.

           (c)   Without limiting the foregoing, if, by reason of any suit or
proceeding of any kind, nature, or description against any Option Care Person
or by any Option Care Person or any other Person against any Lender or the
Lenders' Agent, which in the sole discretion of such


                                      88
<PAGE>

Lender or the Lenders' Agent makes it advisable for such Lender or the
Lenders' Agent to seek counsel for protection and preservation of its liens
and security assets, or to defend its own interest, such expenses and counsel
fees shall be allowed to such Lender and the Lenders' Agent. To the extent
that the undertaking to indemnify, pay and hold harmless set forth in this
SECTION 15.11 may be unenforceable because it is violative of any law or
public policy, each Option Care Person shall contribute the maximum portion
which it is permitted to pay and satisfy under applicable law, to the payment
and satisfaction of all indemnified matters incurred by each Lender or the
Lenders' Agent. The indemnity contained in this SECTION 15.11 shall survive
the payment of the Obligations and the termination of this Agreement. All of
the foregoing costs and expenses shall be part of the Obligations and secured
by the Collateral.

           (d)   Without limiting the foregoing, the Option Care Persons
shall reimburse each Lender and the Lenders' Agent on demand for any amount
paid by such Lender or the Lenders' Agent to a Blocked Account Bank pursuant
to a Blocked Account Agreement.

15.12            WAIVER OF NOTICES. Unless otherwise expressly provided
herein, each Option Care Person waives presentment, protest and notice of
demand or dishonor and protest as to any instrument, as well as any and all
other notices to which it might otherwise be entitled. No notice to or demand
on any Option Care Person which a Lender or the Lenders' Agent may elect to
give shall entitle any Option Care Person to any or further notice or demand
in the same, similar or other circumstances.

15.13            BINDING EFFECT; ASSIGNMENTS; PARTICIPATIONS. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit
of the respective representatives, successors and assigns of the parties
hereto; PROVIDED, HOWEVER, that no interest in this Agreement may be assigned
by any Option Care Person without the prior written consent of the Lenders
and the Lenders' Agent.

           (b)   Any Lender may, with the written consent of the Lenders'
Agent (which consent shall not be unreasonably withheld), assign and delegate
to one or more Eligible Assignees (PROVIDED that no consent of the Lenders'
Agent shall be required in connection with any assignment and delegation by a
Lender to an affiliate of such Lender) (each an "ASSIGNEE") all, or any
ratable part of all, of the Loans, the Commitments and the other rights and
obligations of such Lender hereunder, in a minimum amount of five million
dollars ($5,000,000) (PROVIDED that, unless an assignor Lender has assigned
and delegated all of its Loans and Commitments, no such assignment and/or
delegation shall be permitted unless, after giving effect thereto, such
assignor Lender retains a Commitment in a minimum amount of five million
dollars ($5,000,000); PROVIDED, HOWEVER, that the Borrowers' Agent and the
Lenders' Agent may continue to deal solely and directly with such Lender in
connection with the interest so assigned to an Assignee until (i) written
notice of such assignment, together with payment instructions, addresses and
related information with respect to the Assignee, shall have been given to
the Borrowers' Agent and the Lenders' Agent by such Lender and the Assignee;
(ii) such Lender and its Assignee shall have delivered to the Borrowers'
Agent and the Agent an assignment and acceptance in form and substance
reasonably satisfactory to such Lender, such Assignee and the Lenders' Agent
("ASSIGNMENT AND ACCEPTANCE"); and (iii) the assignor Lender or Assignee has
paid to the Lenders' Agent a processing fee in the amount of three thousand
dollars ($3,000).


                                      89

<PAGE>

         (c)  From and after the date that the Lenders' Agent notifies the
assignor Lender that it has received an executed Assignment and Acceptance and
payment of the above-referenced processing fee, (i) the Assignee thereunder
shall be a party hereto and, to the extent that rights and obligations
hereunder and under the other Loan Documents have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Lender under the Loan Documents, and (ii) the assignor Lender shall, to the
extent that rights and obligations hereunder and under the other Loan Documents
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights and be released from its obligations under this Agreement and the
other Loan Documents (and in the case of an Assignment and Acceptance covering
all or the remaining portion of an assigning Lender's rights and obligations
under this Agreement, such Lender shall cease to be a party hereto).

         (d)  By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other Loan Document furnished
pursuant hereto or the attachment, perfection, or priority of any Lien granted
by the Option Care Persons to the Lenders' Agent or any Lender in the
Collateral; (ii) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of any Option
Care Person or the performance or observance by any Option Care Person of any
of its obligations under this Agreement or any other Loan Document; (iii) such
Assignee confirms that it has received a copy of this Agreement, together with
such other documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into such Assignment and Acceptance;
(iv) such Assignee will, independently and without reliance upon the Lenders'
Agent, such assigning Lender or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement; (v)
such Assignee appoints and authorizes the Lenders' Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Lenders' Agent by the terms hereof, together with such powers,
including the discretionary rights and incidental powers, as are reasonably
incidental thereto; and (vi) such Assignee agrees that it will perform in
accordance with their terms all of the obligations which by the terms of this
Agreement are required to be performed by it as a Lender.

         (e)  Immediately upon satisfaction of the requirements of SECTION
15.13(b), this Agreement shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The Commitment
allocated to each Assignee shall reduce the Commitment of the assigning Lender
PRO TANTO.

         (f)  Any Lender may at any time sell to one or more commercial banks,
financial institutions, or other Persons not Affiliates of any Option Care
Person (a "PARTICIPANT") participating interests in any Loans, the Commitment
of that Lender and the other interests of


                                      90
<PAGE>

that Lender (the "originating Lender") hereunder and under the other Loan
Documents; PROVIDED, HOWEVER, that (i) the originating Lender's obligations
under this Agreement shall remain unchanged, (ii) the originating Lender shall
remain solely responsible for the performance of such obligations, (iii) the
Borrowers' Agent and the Lenders' Agent shall continue to deal solely and
directly with the originating Lender in connection with the originating
Lender's rights and obligations under this Agreement and the other Loan
Documents, and (iv) no Lender shall transfer or grant any participating
interest under which the Participant has rights to approve any modification,
rescission, waiver, release or amendment with respect to this Agreement or any
other Loan Document, and all amounts payable by the Borrowers' Agent or the
Lenders' Agent hereunder shall be determined as if such Lender had not sold
such participation; except that, if amounts outstanding under this Agreement
are due and unpaid, or shall have been declared or shall have become due and
payable upon the occurrence of an Event of Default, each Participant shall be
deemed to have the right of setoff in respect of its participating interest in
amounts owing under this Agreement to the same extent and subject to the same
limitation as if the amount of its participating interest were owing directly
to it as a Lender under this Agreement.

         (g)  Notwithstanding any other provision in this Agreement, any Lender
may at any time create a security interest in, or pledge, all or any portion of
its rights under and interest in this Agreement in favor of any Federal Reserve
Bank in accordance with Regulation A of the Federal Reserve Board or U.S.
Treasury Regulation 31 CFR Section 203.14, and such Federal Reserve may enforce
such pledge or security interest in any manner permitted under applicable law.

15.14      MODIFICATION. This Agreement is intended by the parties hereto to be
the final, complete, and exclusive expression of the agreement between them.
This Agreement supersedes any and all prior oral or written agreements relating
to the subject matter hereof and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no oral
agreements between the parties. No modification, rescission, waiver, release,
or amendment of any provision of this Agreement (including the Schedules and
Exhibits hereto) shall be made, except by a written agreement signed by the
Majority Lenders (or by the Lenders' Agent at the written request of the
Majority Lenders) and the Option Care Persons and then any such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; PROVIDED, HOWEVER, that no such modification,
rescission, waiver, release or amendment shall, unless in writing and signed by
all the Lenders and the Option Care Persons and acknowledged by the Lenders'
Agent, do any of the following:

         (a)  increase or extend the Commitment of any Lender;

         (b)  postpone or delay any date fixed by this Agreement or any other
Loan Document for any payment of principal, interest, fees or other amounts due
to the Lenders (or any of them) hereunder or under any other Loan Document;

         (c)  reduce the principal of, or the rate of interest specified herein
on any Loan, or any fees or other amounts payable hereunder or under any other
Loan Document;


                                      91
<PAGE>

         (d)  change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which is required for the Lenders or any
of them to take any action hereunder;

         (e)  increase any of the percentages set forth in the definition of
Availability;

         (f)  amend this Section or any provision of this Agreement providing
for consent or other action by all Lenders or by the Majority Lenders;

         (g)  release Collateral other than as permitted by the terms of this
Agreement;

         (h)  change the definitions of "Majority Lenders"; or

         (i)  increase the Maximum Revolving Credit Line or the Term Loan
Commitment.

15.15      COUNTERPARTS. This Agreement may be executed in any number of
counterparts, and by the parties hereto in separate counterparts, each of which
shall be an original, but all of which shall together constitute one and the
same agreement; signature pages may be detached from multiple separate
counterparts and attached to a single counterpart so that all signature pages
are physically attached to the same document.

15.16      CAPTIONS. The captions contained in this Agreement or any other Loan
Document (including without limitation the table of contents and the exhibits
and schedules hereto or thereto) are for convenience only, are without
substantive meaning and should not be construed to modify, enlarge, or restrict
any provision.

15.17      RIGHT OF SET-OFF. In addition to any rights and remedies of the
Lenders provided under this Agreement or any other Loan Document or under
applicable law, whenever an Event of Default exists, each Lender is hereby
authorized at any time and from time to time, without prior notice to any
Option Care Person, any such notice being waived by each Option Care Person to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender or any affiliate of such
Lender to or for the credit or the account of any Option Care Person against
any and all of the Obligations owing to such Lender, whether or not then due
and payable without prior notice to each Option Care Person, any such notice
being waived by any Option Care Person to the fullest extent permitted by law.
Each Lender agrees to notify the Borrowers' Agent and the Lenders' Agent
promptly after any such setoff and application made by such Lender; PROVIDED,
HOWEVER, that the failure to give such notice shall not affect the validity of
such setoff and application. NOTWITHSTANDING THE FOREGOING, NO LENDER SHALL
EXERCISE ANY RIGHT OF SET-OFF, BANKER'S LIEN, OR THE LIKE AGAINST ANY DEPOSIT
ACCOUNT OR PROPERTY OF ANY OPTION CARE PERSON HELD OR MAINTAINED BY SUCH LENDER
WITHOUT THE PRIOR WRITTEN UNANIMOUS CONSENT OF THE LENDERS.

15.18      [Reserved].

15.19      ADDITIONAL BORROWERS. Any Subsidiary wholly owned by Option Care (or
wholly owned by any Subsidiary of Option Care) that is not a Borrower party
hereto on the Closing Date may become a Borrower party to this Agreement upon
the satisfaction of the


                                      92
<PAGE>

following conditions: (a) such Subsidiary and Option Care shall have signed and
delivered to the Lenders an agreement substantially in the form of EXHIBIT B
hereto (an "ADDITIONAL BORROWER AGREEMENT"); (b) each Lender shall have
received such other documents, agreements, instruments and opinions as it may
reasonably request in connection with such Subsidiary becoming a Borrower,
which shall be in form and substance reasonably satisfactory to such Lender,
including without limitation items of the type delivered pursuant to SECTION
11.1; (c) each Lender shall have had a reasonable period of time to conduct
(and to cause one or more of its agents or representatives to conduct) due
diligence with respect to such Subsidiary, such Subsidiary and the Option Care
Persons shall have fully cooperated with the Lenders and such agents and
representatives in connection with such due diligence, and the results of such
due diligence are satisfactory to the Lenders; (d) such Subsidiary shall be in
the same line of business that one or more of the Borrowers were engaged in on
the Closing Date; and (e) the Lenders shall have sent the Borrowers' Agent a
notice substantially in the form of EXHIBIT C hereto (an "ADDITIONAL BORROWER
CONSENT NOTICE").

15.20      JOINT AND SEVERAL LIABILITY. (a) The Borrowers shall be jointly and
severally liable for all Loans and other amounts due to the Lenders and the
Lenders' Agent under this Agreement, regardless of which Borrower actually
receives Loans or other extensions of credit hereunder or the amount of such
Loans received or the manner in which the Lender accounts for such Loans or
other extensions of credit on its books and records. Each Borrower's
Obligations with respect to Loans made to it, and each Borrower's Obligations
arising as a result of the joint and several liability of the Borrowers
hereunder with respect to Loans made to the other Borrowers hereunder, shall be
separate and distinct obligations, but all such Obligations shall be primary
obligations of such Borrower.

         (b)  Each Borrower's Obligations arising as a result of the joint and
several liability of such Borrower hereunder with respect to Loans or other
extensions of credit made to the other Borrowers hereunder shall, to the
fullest extent permitted by law, be absolute and unconditional irrespective of
(i) the validity, legality, enforceability, avoidance or subordination of the
Obligations of any other Borrower or of any promissory note or other document
evidencing all or any part of the Obligations of any other Borrower, (ii) the
absence of any attempt to collect the Obligations from any other Borrower, any
other guarantor, or any other security therefor, or the absence of any other
action to enforce the same, (iii) the waiver, consent, extension, forbearance
or granting of any indulgence by any Lender or the Lenders' Agent with respect
to any Obligations or any provision of any instrument evidencing the
Obligations of any other Borrower, or any part thereof, or any other agreement
now or hereafter executed by any other Borrower and delivered to any Lender or
the Lenders' Agent, (iv) the failure by any Lender or the Lenders' Agent to
take any steps to perfect and maintain its security interest in, or to preserve
its rights to, any security or collateral for the Obligations of any other
Borrower, (v) the election of any Lender or of the Lenders' Agent, in any
proceeding instituted under the Federal Bankruptcy Code, of the application of
Section 1111(b)(2) of the Federal Bankruptcy Code, (vi) any borrowing or grant
of a security interest by any other Borrower, as debtor-in-possession, under
Section 364 of the Federal Bankruptcy Code, (vii) the disallowance of all or
any portion of the Lender's claim(s) for the repayment of the Obligations of
any other Borrower under Section 502 of the Federal Bankruptcy Code, or (viii)
any other events, conditions or circumstances which might constitute a legal or
equitable discharge or defense of a guarantor or of a surety or of any
Borrower. With respect to any Borrower's Obligations arising as a result of the
joint and several liability of the Borrowers hereunder with respect to Loans or
other extensions or credit


                                      93
<PAGE>

made to any other Borrower hereunder, each Borrower waives, until all of the
Obligations shall have been paid in full and this Agreement shall have been
terminated, any right to enforce any right of subrogation or any remedy which
any Lender or the Lenders' Agent now has or may hereafter have against any
Borrower, any endorser or any guarantor of all or any part of the Obligations,
and any benefit of, and any right to participate in, any security or collateral
given to any Lender or the Lenders' Agent to secure payment of the Obligations
or any other liability of any Borrower to the Lender.

         (c)  Upon any Event of Default, the Lenders' Agent may proceed
directly and at once, without notice, against any Borrower to collect and
recover the full amount, or any portion of, the Obligations, without first
proceeding against any other Borrower or any other Person, or against any
security or collateral for the Obligations. Each Borrower consents and agrees
that neither the Lender nor the Lenders' Agent shall be under any obligation to
marshal any assets in favor of any Borrower or against or in payment of any or
all of the Obligations.

         (d)  Notwithstanding the other provisions of this Agreement, each
Option Care Person shall be liable under this Agreement only for the maximum
amount of such liability that can hereby be incurred without rendering its
obligations under this Agreement voidable under applicable law relating to
fraudulent conveyance or fraudulent transfer, and not for any greater amount.

15.21      EFFECT ON EXISTING LOAN AND SECURITY AGREEMENT. This Agreement
amends and restates the Existing Loan and Security Agreement effective as of
the date of this Agreement. This Agreement shall not effect a novation of the
obligations of the parties to the Existing Loan and Security Agreement, but
instead shall be merely a restatement and, where applicable, an amendment of
the terms governing such obligations. The parties hereto hereby affirm, ratify
and confirm all transactions pursuant to the Existing Loan and Security
Agreement.

15.22      OBLIGATIONS OF LENDERS. The obligations of the Lenders under this
Agreement or any other Loan Document shall be several and not joint.

16.      THE AGENT.

16.1       APPOINTMENT AND AUTHORIZATION. Each Lender hereby designates and
appoints the Bank as the Lenders' Agent under this Agreement and the other Loan
Documents and each Lender hereby irrevocably authorizes the Lenders' Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto. The
Lenders' Agent agrees to act as such on the express conditions contained in
SECTIONS 16.1 through 16.17. The provisions of SECTIONS 16.1 through 16.17
applicable to the Lenders' Agent are solely for the benefit of the Lenders'
Agent, and the Lenders and the Option Care Persons shall have no rights as a
third party beneficiary of any of the provisions contained herein.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Lenders' Agent shall not have any
duties or responsibilities, except those expressly set forth herein, nor shall
the Lenders' Agent have or be deemed to have any fiduciary relationship with
any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the Lenders' Agent. Without limiting the
generality of the foregoing


                                      94
<PAGE>

sentence, the use of the term "agent" in this Agreement with reference to the
Lenders' 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. Except as expressly otherwise provided in this Agreement,
the Lenders' Agent shall have and may use its sole discretion with respect to
exercising or refraining from exercising any discretionary rights or taking or
refraining from taking any actions which the Lenders' Agent is expressly
entitled to take or assert under this Agreement and the other Loan Documents,
including (a) the determination of the applicability of ineligibility criteria
with respect to the determination of the Eligible Accounts, (b) the making of
Lenders' Agent Advances pursuant to SECTION 2.2, and (c) the exercise of
remedies pursuant to this Agreement and any other Loan Document, and any action
so taken or not taken shall be deemed consented to by the Lenders.

16.2     DELEGATION OF DUTIES. The Lenders' Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Lenders' Agent shall not be responsible
for the negligence or misconduct of any agent or attorney-in-fact that it
selects as long as such selection was made without gross negligence or willful
misconduct.

16.3     LIABILITY OF THE LENDERS' AGENT RELATED PERSONS. None of the Lenders'
Agent Related Persons shall (i) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement or any other
Loan Document or the transactions contemplated hereby (except for its own gross
negligence or willful misconduct), or (ii) be responsible in any manner to any
of the Lenders for any recital, statement, representation or warranty made by
any Option Care Person or any Subsidiary or Affiliate of the any Option Care
Person, or any officer thereof, contained in this Agreement or in any other
Loan Document, or in any certificate, report, statement or other document
referred to or provided for in, or received by the Lenders' Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of any Option Care Person or any
other party to any Loan Document to perform its obligations hereunder or
thereunder. No Lenders' Agent Related Person shall be under any obligation to
any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of any
Option Care Person or any of the Subsidiaries or Affiliates of any Option Care
Person.

16.4     RELIANCE BY THE LENDERS' AGENT. The Lenders' Agent shall be entitled
to rely, and shall be fully protected in relying, upon any writing, resolution,
notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or
telephone message, statement or other document or conversation believed by it
to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons, and upon advice and statements of legal counsel (including
counsel to any Option Care Person), independent accountants and other experts
selected by the Lenders' Agent. The Lenders' Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Lenders as it deems appropriate and, if it so requests, it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action.


                                      95

<PAGE>

The Lenders' Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Majority Lenders and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all of the Lenders.

16.5     NOTICE OF DEFAULT.  The Lenders' Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default,
unless the Lenders' Agent shall have received written notice from a Lender or
the Borrowers' Agent referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default." The
Lenders' Agent shall notify the Lenders of its receipt of any such notice.
The Lenders' Agent shall take such action with respect to such Default or
Event of Default as may be requested by the Majority Lenders in accordance
with this Agreement; PROVIDED, HOWEVER, that unless and until the Lenders'
Agent has received any such request, the Lenders' Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable.

16.6     CREDIT DECISION.  Each Lender acknowledges that none of the Lenders'
Agent Related Persons has made any representation or warranty to it, and that
no act by the Lenders' Agent hereinafter taken, including any review of the
affairs of any Option Care Person and any Affiliates of any Option Care
Person, shall be deemed to constitute any representation or warranty by any
Lenders' Agent-Related Person to any Lender. Each Lender represents to the
Lenders' Agent that it has, independently and without reliance upon any
Lenders' Agent-Related Person and based on such documents and information as
it has deemed appropriate, made its own appraisal of and investigation into
the business, prospects, operations, property, financial and other condition
and creditworthiness of the Option Care Persons and the Affiliates of the
Option Care Persons, and all applicable bank regulatory laws relating to the
transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Borrowers. Each Lender also
represents that it shall, independently and without reliance upon any
Lenders' Agent-Related Person and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigations as it
deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Option
Care Persons. Except for any documents expressly herein required to be
furnished to the Lenders by the Lenders' Agent, the Lenders' Agent shall not
have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of the Option Care Persons
which may come into the possession of any of the Lenders' Agent Related
Persons.

16.7     INDEMNIFICATION.  Whether or not the transactions contemplated
hereby are consummated, the Lenders shall indemnify upon demand the Lenders'
Agent Related Persons (to the extent not reimbursed by or on behalf of the
Option Care Persons and without limiting the obligation of the Option Care
Persons to do so), pro rata based on their Pro Rata Shares, from and against
any and all Indemnified Liabilities as such term is defined in SECTION 15.11
(including any amounts paid by the Lenders' Agent under or in connection with
a Blocked Account Agreement); PROVIDED, HOWEVER, that no Lender shall be
liable for the payment to the Lenders' Agent Related Persons of any portion
of such Indemnified Liabilities resulting solely from the gross negligence or
willful misconduct of a Lenders' Agent Related Person. Without limitation of
the foregoing, each Lender shall reimburse the Lenders' Agent upon demand for
its

                                96

<PAGE>

ratable share of any costs or out-of-pocket expenses (including fees and
disbursements of counsel) incurred by the Lenders' Agent in connection with
the preparation, execution, delivery, administration, modification, amendment
or enforcement (whether through negotiations, legal proceedings or otherwise)
of, or legal advice in respect of rights or responsibilities under, this
Agreement, any other Loan Document, or any document contemplated by or
referred to herein, to the extent that the Lenders' Agent is not reimbursed
for such expenses by or on behalf of the Option Care Persons. The undertaking
in this Section shall survive the payment of all Obligations hereunder and
the resignation or replacement of the Lenders' Agent.

16.8     LENDERS' AGENT IN INDIVIDUAL CAPACITY.  The Bank and its Affiliates
may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind
of banking, trust, financial advisory, underwriting or other business with
any Option Care Person and the Affiliates of any Option Care Person as though
the Bank were not the Lenders' Agent hereunder and without notice to or
consent of the Lenders. The Lenders acknowledge that, pursuant to such
activities, the Bank or its Affiliates may receive information regarding the
Option Care Persons and Affiliates of the Option Care Persons (including
information that may be subject to confidentiality obligations in favor of an
Option Care Person or an Affiliate of an Option Care Person) and acknowledge
that the Lenders' Agent and the Bank shall be under no obligation to provide
such information to them. With respect to its Loans, the Bank shall have the
same rights and powers under this Agreement as any other Lender and may
exercise the same as though it were not the Lenders' Agent, and the terms
"Lender" and "Lenders" include the Bank in its individual capacity.

16.9     SUCCESSOR AGENT.  The Lenders' Agent may resign as Lenders' Agent
upon sixty (60) days' notice to the Lenders and the Borrower, such
resignation to be effective upon the acceptance of a successor agent to its
appointment as Lenders' Agent. In the event the Bank sells all of its
Commitment and Loans as part of a sale, transfer or other disposition by the
Bank of substantially all of its loan portfolio, the Bank shall resign as
Lenders' Agent and such purchaser or transferee shall become the successor
Lenders' Agent hereunder. If the Lenders' Agent resigns under this Agreement,
subject to the proviso in the preceding sentence, the Majority Lenders shall
appoint from among the Lenders a successor agent for the Lenders. If no
successor agent is appointed prior to the effective date of the resignation
of the Lenders' Agent, the Lenders' Agent may appoint, after consulting with
the Lenders and the Borrowers' Agent, a successor agent from among the
Lenders. Upon the acceptance of its appointment as successor agent hereunder,
such successor agent shall succeed to all the rights, powers and duties of
the retiring Lenders' Agent and the term "Lenders' Agent" shall mean such
successor agent and the retiring Lenders' Agent's appointment, powers and
duties as Lenders' Agent shall be terminated. After any retiring Lenders'
Agent's resignation hereunder as Lenders' Agent, the provisions of SECTIONS
16.1 through 16.17 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Lenders' Agent under this Agreement.

16.10    WITHHOLDING TAX.  (a) If any Lender is a "foreign corporation,
partnership or trust" within the meaning of the Code and such Lender claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441
or 1442 of the Code, such Lender agrees with and in favor of the Lenders'
Agent, to deliver to the Lenders' Agent:

              (i) if such Lender claims an exemption from, or a reduction of,
withholding tax under a United States of America tax treaty, properly completed
IRS Form W-8BEN before the payment of any interest in the first calendar year
and before the payment of


                                97

<PAGE>

any interest in each third succeeding calendar year during which interest may be
paid under this Agreement;

              (ii) if such Lender claims that interest paid under this
Agreement is exempt from United States of America withholding tax because it
is effectively connected with a United States of America trade or business of
such Lender, two properly completed and executed copies of IRS Form W-8ECI
before the payment of any interest is due in the first taxable year of such
Lender and in each succeeding taxable year of such Lender during which interest
may be paid under this Agreement, and IRS Form W-9; and

              (iii) such other form or forms as may be required under the
Code or other laws of the United States of America as a condition to
exemption from, or reduction of, United States of America withholding tax.

Such Lender agrees to promptly notify the Lenders' Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

         (b) If any Lender claims exemption from, or reduction of,
withholding tax under a United States of America tax treaty by providing IRS
Form W-8BEN and such Lender sells, assigns, grants a participation in, or
otherwise transfers all or part of the Obligations owing to such Lender, such
Lender agrees to notify the Lenders' Agent of the percentage amount in which
it is no longer the beneficial owner of Obligations of the Borrowers to such
Lender. To the extent of such percentage amount, the Lenders' Agent shall
treat such Lender's IRS Form W-8BEN as no longer valid.

         (c) If any Lender claiming exemption from United States of America
withholding tax by filing IRS Form W-8ECI with the Lenders' Agent sells,
assigns, grants a participation in, or otherwise transfers all or part of the
Obligations owing to such Lender, such Lender agrees to undertake sole
responsibility for complying with the withholding tax requirements imposed by
Sections 1441 and 1442 of the Code.

         (d) If any Lender is entitled to a reduction in the applicable
withholding tax, the Lenders' Agent may withhold from any interest payment to
such Lender an amount equivalent to the applicable withholding tax after
taking into account such reduction. If the forms or other documentation
required by subsection (a) of this Section are not delivered to the Lenders'
Agent, then the Lenders' Agent may withhold from any interest payment to such
Lender not providing such forms or other documentation an amount equivalent
to the applicable withholding tax.

         (e) If the IRS or any other Governmental Authority of the United
States of America or other jurisdiction asserts a claim that the Lenders'
Agent did not properly withhold tax from amounts paid to or for the account
of any Lender (because the appropriate form was not delivered, was not
properly executed, or because such Lender failed to notify the Lenders' Agent
of a change in circumstances which rendered the exemption from, or reduction
of, withholding tax ineffective, or for any other reason) such Lender shall
indemnify the Lenders' Agent fully for all amounts paid, directly or
indirectly, by the Lenders' Agent as tax or

                                98

<PAGE>

otherwise, including penalties and interest, and including any taxes imposed
by any jurisdiction on the amounts payable to the Lenders' Agent under this
Section, together with all costs and expenses (including fees and
disbursements of counsel). The obligation of the Lenders under this
subsection shall survive the payment of all Obligations and the resignation
or replacement of the Lenders' Agent.

16.11    COLLATERAL MATTERS.

(a)           The Lenders hereby irrevocably authorize the Lenders' Agent, at
its option and in its sole discretion, to release any Lenders' Agent's Lien
upon any Collateral (i) upon the termination of the Commitments and payment
and satisfaction in full by Borrowers of all Loans and all other Obligations;
(ii) constituting property being sold or disposed of if the Borrowers' Agent
certifies to the Lenders' Agent that the sale or disposition is made in
compliance with the terms of this Agreement (and the Lenders' Agent may rely
conclusively on any such certificate, without further inquiry); (iii)
constituting property in which the Borrowers owned no interest at the time
the Lien was granted or at any time thereafter; or (iv) constituting property
leased to a Borrower under a lease which has expired or been terminated in a
transaction permitted under this Agreement. Except as provided above, the
Lenders' Agent shall not release any of the Lenders' Agent's Liens without
the prior written authorization of the Lenders; PROVIDED that the Lenders'
Agent may, in its discretion, release the Lenders' Agent's Liens on
Collateral valued in the aggregate not in excess of one hundred thousand
dollars ($100,000) during any one year period without the prior written
authorization of the Lenders. Upon request by the Lenders' Agent or the
Borrowers' Agent at any time, the Lenders shall confirm in writing the
Lenders' Agent's authority to release any Lenders' Agent's Liens upon
particular types or items of Collateral pursuant to this SECTION 16.11.

(b)           Upon receipt by the Lenders' Agent of any authorization
required pursuant to clause (a) above from the Lenders of the Lenders'
Agent's authority to release any Lenders' Agent's Liens upon particular types
or items of Collateral, and upon at least five (5) Business Days prior
written request by the Borrowers' Agent, the Lenders' Agent shall (and is
hereby irrevocably authorized by the Lenders to) execute such documents as
may be necessary to evidence the release of the Lenders' Agent's Liens upon
such Collateral; PROVIDED, HOWEVER, that (i) the Lenders' Agent shall not be
required to execute any such document on terms which, in the Lenders' Agent's
opinion, would expose the Lenders' Agent to liability or create any
obligation or entail any consequence other than the release of such Liens
without recourse or warranty, and (ii) such release shall not in any manner
discharge, affect or impair the Obligations or any Liens (other than those
expressly being released) upon (or obligations of any Borrower in respect of)
all interests retained by any Borrower, including the proceeds of any sale,
all of which shall continue to constitute part of the Collateral.

(c)           The Lenders' Agent shall have no obligation whatsoever to any
of the Lenders to assure that the Collateral exists or is owned by any
Borrower or is cared for, protected or insured or has been encumbered, or
that the Lenders' Agent's Liens have been properly or sufficiently or
lawfully created, perfected, protected or enforced or are entitled to any
particular priority, or to exercise at all or in any particular manner or
under any duty of care, disclosure or fidelity, or to continue exercising,
any of the rights, authorities and powers granted or available to the
Lenders' Agent pursuant to any of the Loan Documents, it being understood

                                99

<PAGE>

and agreed that in respect of the Collateral, or any act, omission or event
related thereto, the Lenders' Agent may act in any manner it may deem
appropriate, in its sole discretion given the Lenders' Agent's own interest
in the Collateral in its capacity as one of the Lenders and that the Lenders'
Agent shall have no other duty or liability whatsoever to any Lender as to
any of the foregoing.

16.12    RESTRICTIONS ON ACTIONS BY LENDERS; SHARING OF PAYMENTS. (a) Each of
the Lenders agrees that it shall not, without the express consent of all
Lenders, and that it shall, to the extent it is lawfully entitled to do so,
upon the request of all Lenders, set off against the Obligations, any amounts
owing by such Lender to the Borrowers or any accounts of the Borrowers now or
hereafter maintained with such Lender. Each of the Lenders further agrees
that it shall not, unless specifically requested to do so by the Lenders'
Agent, take or cause to be taken any action to enforce its rights under this
Agreement or against any Option Care Person, including the commencement of
any legal or equitable proceedings, to foreclose any Lien on, or otherwise
enforce any security interest in, any of the Collateral.

              (b) If at any time or times any Lender shall receive (i) by
payment, foreclosure, setoff or otherwise, any proceeds of Collateral or any
payments with respect to the Obligations of the Borrowers to such Lender
arising under, or relating to, this Agreement or the other Loan Documents,
except for any such proceeds or payments received by such Lender from the
Lenders' Agent pursuant to the terms of this Agreement, or (ii) payments from
the Lenders' Agent in excess of such Lender's ratable portion of all such
distributions by the Lenders' Agent, such Lender shall promptly (1) turn the
same over to the Lenders' Agent, in kind, and with such endorsements as may
be required to negotiate the same to the Lenders' Agent, or in same day
funds, as applicable, for the account of all of the Lenders and for
application to the Obligations in accordance with the applicable provisions
of this Agreement, or (2) purchase, without recourse or warranty, an
undivided interest and participation in the Obligations owed to the other
Lenders so that such excess payment received shall be applied ratably as
among the Lenders in accordance with their Pro Rata Shares; PROVIDED,
HOWEVER, that if all or part of such excess payment received by the
purchasing party is thereafter recovered from it, those purchases of
participations shall be rescinded in whole or in part, as applicable, and the
applicable portion of the purchase price paid therefor shall be returned to
such purchasing party, but without interest except to the extent that such
purchasing party is required to pay interest in connection with the recovery
of the excess payment.

16.13    AGENCY FOR PERFECTION. Each Lender hereby appoints each other Lender
as agent for the purpose of perfecting the Lenders' security interest in
assets which, in accordance with Article 9 of the UCC can be perfected only
by possession. Should any Lender (other than the Lenders' Agent) obtain
possession of any such Collateral, such Lender shall notify the Lenders'
Agent thereof, and, promptly upon the Lenders' Agent's request therefor shall
deliver such Collateral to the Lenders' Agent or in accordance with the
Lenders' Agent's instructions.

16.14    PAYMENTS BY THE LENDERS' AGENT TO LENDERS. All payments to be made
by the Lenders' Agent to the Lenders shall be made by bank wire transfer or
internal transfer of immediately available funds to each Lender pursuant to
wire transfer instructions delivered in writing to the Lenders' Agent on or
prior to the Closing Date (or if such Lender is an Assignee, in the
applicable Assignment and Acceptance), or pursuant to such other wire
transfer instructions as each party may designate for itself by written
notice to the Lenders' Agent.

                                100

<PAGE>

Concurrently with each such payment, the Lenders' Agent shall identify
whether such payment (or any portion thereof) represents principal or
interest on the Revolving Loans, Term Loans or otherwise.

16.15    CONCERNING THE COLLATERAL AND THE RELATED LOAN DOCUMENTS. Each
Lender authorizes and directs the Lenders' Agent to enter into this Agreement
and the other Loan Documents, for the ratable benefit and obligation of the
Lenders' Agent and the Lenders. Each Lender agrees that any action taken by
the Lenders' Agent or Majority Lenders, as applicable, in accordance with the
terms of this Agreement or the other Loan Documents, and the exercise by the
Lenders' Agent or the Majority Lenders, as applicable, of their respective
powers set forth therein or herein, together with such other powers that are
reasonably incidental thereto, shall be binding upon all of the Lenders.

16.16    FIELD AUDIT AND EXAMINATION REPORTS; DISCLAIMER BY LENDERS. Each
Lender:

(a)           shall be deemed to have requested that the Lenders' Agent
furnish such Lender, promptly after it becomes available, a copy of each
field audit or examination report (each a "REPORT" and collectively,
"REPORTS") prepared by the Lenders' Agent;

(b)           expressly agrees and acknowledges that neither the Bank nor the
Lenders' Agent (i) makes any representation or warranty as to the accuracy of
any Report, or (ii) shall be liable for any information contained in any
Report;

(c)           expressly agrees and acknowledges that the Reports are not
comprehensive audits or examinations, that the Lenders' Agent or the Bank or
other party performing any audit or examination shall inspect only specific
information regarding the Option Care Persons and shall rely significantly
upon the books and records of the Option Care Persons, as well as on
representations of the personnel of the Option Care Persons;

(d)           agrees to keep all Reports confidential and strictly for its
internal use, and not to distribute except to its participants, or use any
Report in any other manner; and

(e)           without limiting the generality of any other indemnification
provision contained in this Agreement, agrees: (i) to hold the Lenders' Agent
harmless from any action the indemnifying Lender may take or conclusion the
indemnifying Lender may reach or draw from any Report in connection with any
loans or other credit accommodations that the indemnifying Lender has made or
may make to the Borrower, or the indemnifying Lender's participation in, or
the indemnifying Lender's purchase of, a loan or loans of the Borrowers; and
(ii) to pay and protect, and indemnify, defend and hold the Lenders' Agent
harmless from and against, the claims, actions, proceedings, damages, costs,
expenses and other amounts (including fees and disbursements of counsel)
incurred by the Lenders' Agent preparing a Report as the direct or indirect
result of any third parties who might obtain all or part of any Report
through the indemnifying Lender.

16.17    RELATION AMONG LENDERS. The Lenders are not partners or
co-venturers, and no Lender shall be liable for the acts or omissions of, or
(except as otherwise set forth herein in case of the Lenders' Agent)
authorized to act for, any other Lender.

16.18    ASSIGNMENT AND PURCHASE OF PRO RATA SHARE. On the Closing Date, Bank
of America, N.A. agrees to assign to LaSalle Bank National Association, and
LaSalle Bank

                                101

[Name and address of Account Debtor]

To Whom It May Concern:

           We are pleased to announce that we have entered into a revolving loan
agreement with Bank of America, N.A., the other lenders party thereto from time
to time, and Bank of America, N.A., as agent for those lenders (in such
capacity, together with its successors and assigns in such capacity, the
"Agent"). In connection with that agreement, we have granted a continuing
security interest to the Agent in our existing and future receivables and other
amounts which you may owe us from time to time.

           Such security interest will continue in effect until such time as the
Agent otherwise notifies you in writing. We hereby revoke any notice we may have
given you previously with regard to any security interest granted (or transfer
made) by us to any person or entity other than the Agent.

           If you have any questions about this notice or anything else, please
contact the undersigned.

                                       Very truly yours,

                                       [NAME OF BORROWER]
