     required for any reason to pay over to an Obligor (or any trustee,
     receiver, custodian or similar official in any Insolvency Proceeding) any
     amount received by it hereunder, such amount shall be deemed not to have
     been so received by the Administrator or the Issuer but rather to have been
     retained by the Seller and, accordingly, the Administrator or the Issuer,

     payable when and to the extent that any distribution from or on behalf of
     such Obligor is made in respect thereof.

     Seller, on the proposed date of commencement of such reduction and on each
     day thereafter, the Servicer shall cause Collections with respect to such
     Portion of Capital not to be reinvested until the amount thereof not so
     reinvested shall equal the desired amount of reduction and the Servicer
     shall hold such Collections in trust for the Purchasers, for payment to the
     Administrator on the last day of the current Settlement Period relating to

the account of such Affected Person, from time to time as specified by such
Affected Person, additional amounts sufficient to compensate such Affected
Person in the light of such circumstances, to the extent that such Affected
Person reasonably determines such increase in capital to be allocable to the
existence of any of such commitments. A certificate as to such amounts submitted
to the Seller and the Administrator by such Affected Person shall be conclusive
and binding for all purposes, absent manifest error.

          (b)    If, due to either: (i) the introduction of or any change in or
in the interpretation of any law or regulation or (ii) compliance with any
guideline or request from any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to any Affected Person of agreeing to purchase or purchasing, or
maintaining the ownership of, the Purchased Interest in respect of which
Discount is computed by reference to the Euro-Rate, then, upon demand by such
Affected Person, the Seller shall promptly pay to such Affected Person, from
time to time as specified by such Affected Person, additional amounts sufficient
to compensate such Affected Person for such increased costs. A certificate as to
such amounts submitted to the Seller and the Administrator by such Affected
Person shall be conclusive and binding for all purposes, absent manifest error.

          (c)    If such increased costs affect the related Affected Person's
portfolio of financing transactions, such Affected Person shall use reasonable
averaging and attribution methods to allocate such increased costs to the
transactions contemplated by this Agreement.

     SECTION 1.8 Requirements of Law. If any Affected Person reasonably
                 -------------------
determines that the existence of or compliance with: (a) any law or regulation
or any change therein or in the interpretation or application thereof, in each
case adopted, issued or occurring after the date hereof, or (b) any request,
guideline or directive from any central bank or other Governmental Authority
(whether or not having the force of law) issued or occurring after the date of
this Agreement:

          (i)    does or shall subject such Affected Person to any tax of any
     kind whatsoever with respect to this Agreement, any increase in the
     Purchased Interest or in the amount of Capital relating thereto, or does or
     shall change the basis of taxation of payments to such Affected Person on
     account of Collections, Discount or any other amounts payable hereunder
     (excluding taxes imposed on the overall pre-tax net income of such Affected
     Person, and franchise taxes imposed on such Affected Person, by the
     jurisdiction under the laws of which such Affected Person is organized or a
     political subdivision thereof),

          (ii)   does or shall impose, modify or hold applicable any reserve,
     special deposit, compulsory loan or similar requirement against assets held
     by, or deposits or other liabilities in or for the account of, purchases,
     advances or loans by, or other credit extended by, or any other acquisition
     of funds by, any office of such Affected Person that are not otherwise
     included in the determination of the Euro-Rate or the Base Rate hereunder,
     or

          (iii)  does or shall impose on such Affected Person any other expense
     or liability with respect to the transactions contemplated by this
     Agreement,

                                       7          Receivables Purchase Agreement
<PAGE>

and the result of any of the foregoing is: (A) to increase the cost to such
Affected Person of acting as Administrator, or of agreeing to purchase or
purchasing or maintaining the ownership of undivided percentage ownership
interests with regard to the Purchased Interest (or interests therein) or any
Portion of Capital, or (B) to reduce any amount receivable hereunder (whether
directly or indirectly), then, in any such case, upon demand by such Affected
Person, the Seller shall promptly pay to such Affected Person additional amounts
necessary to compensate such Affected Person for such additional cost or reduced
amount receivable. All such amounts shall be payable as incurred. A certificate
from such Affected Person to the Seller and the Administrator certifying, in
reasonably specific detail, the basis for, calculation of, and amount of such
additional costs or reduced amount receivable shall be conclusive and binding
for all purposes, absent manifest error; provided, however, that no Affected
                                         --------  -------
Person shall be required to disclose any confidential or tax planning
information in any such certificate.

     SECTION 1.9 Inability to Determine Euro-Rate. (a) If the Administrator
                 --------------------------------
determines before the first day of any Settlement Period (which determination
shall be final and conclusive) that, by reason of circumstances affecting the
interbank eurodollar market generally, deposits in dollars (in the relevant
amounts for such Settlement Period) are not being offered to banks in the
interbank eurodollar market for such Settlement Period, or adequate means do not
exist for ascertaining the Euro-Rate for such Settlement Period, then the
Administrator shall give notice thereof to the Seller. Thereafter, until the
Administrator notifies the Seller that the circumstances giving rise to such
suspension no longer exist, (a) no Portion of Capital shall be funded at the
Alternate Rate determined by reference to the Euro-Rate and (b) the Discount for
any outstanding Portions of Capital then funded at the Alternate Rate determined
by reference to the Euro-Rate shall, on the last day of the then current
Settlement Period, be converted to the Alternate Rate determined by reference to
the Base Rate.

          (b)    If, on or before the first day of any Settlement Period, the
Administrator shall have been notified by any Purchaser that such Purchaser has
determined (which determination shall be final and conclusive) that, any
enactment, promulgation or adoption of or any change in any applicable law, rule
or regulation, or any change in the interpretation or administration thereof by
a governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Purchaser with
any guideline, request or directive (whether or not having the force of law) of
any such authority, central bank or comparable agency shall make it unlawful or
impossible for such Purchaser to fund or maintain any Portion of Capital at the
Alternate Rate and based upon the Euro-Rate, the Administrator shall notify the
Seller thereof. Upon receipt of such notice, until the Administrator notifies
the Seller that the circumstances giving rise to such determination no longer
apply, (a) no Portion of Capital shall be funded at the Alternate Rate
determined by reference to the Euro-Rate and (b) the Discount for any
outstanding Portions of Capital then funded at the Alternate Rate determined by
reference to the Euro-Rate shall be converted to the Alternate Rate determined
by reference to the Base Rate either (i) on the last day of the then current
Settlement Period if such Purchaser may lawfully continue to maintain such
Portion of Capital at the Alternate Rate determined by reference to the Euro-
Rate to such day, or (ii) immediately, if such Purchaser may not lawfully
continue to maintain such Portion of Capital at the Alternate Rate determined by
reference to the Euro-Rate to such day.

                        ADMINISTRATION AND COLLECTIONS

     SECTION 4.1 Appointment of the Servicer. (a) The servicing, administering
                 ---------------------------
and collection of the Pool Receivables shall be conducted by the Person so
designated from time to time as the Servicer in accordance with this Section.
Until the Administrator gives notice to IMCO (in accordance with this Section)
of the designation of a new Servicer, IMCO is hereby designated as, and hereby
agrees to perform the duties and obligations of, the Servicer pursuant to the
terms hereof. Upon the occurrence of a Termination Event (but not prior
thereto), the Administrator may designate as Servicer any Person (including
itself) to succeed IMCO or any successor Servicer, on the condition in each case
that any such Person so designated shall agree to perform the duties and
obligations of the Servicer pursuant to the terms hereof.

          (b)    Upon the designation of a successor Servicer as set forth in
clause (a), IMCO agrees that it will terminate its activities as Servicer
---------
hereunder in a manner that the Administrator determines will facilitate the
transition of the performance of such activities to the new Servicer, and IMCO
shall cooperate with and assist such new Servicer. Such cooperation shall
include access to and transfer of related records and use by the new Servicer of
all licenses, hardware or software necessary or desirable to collect the Pool
Receivables and the Related Security.

          (c)    IMCO acknowledges that, in making their decision to execute and
deliver this Agreement, the Administrator and the Issuer have relied on IMCO's
agreement to act as Servicer hereunder. Accordingly, IMCO agrees that it will
not voluntarily resign as Servicer.

<PAGE>

          (d)  The Servicer may delegate its duties and obligations hereunder to
any subservicer (each a "Sub-Servicer"); provided, that, in each such
                         ------------    --------
delegation: (i) such Sub-Servicer shall agree in writing to perform the duties
and obligations of the Servicer pursuant to the terms hereof, (ii) the Servicer
shall remain primarily liable for the performance of the duties and obligations
so delegated, (iii) the Seller, the Administrator and the Issuer shall have the
right to look solely to the Servicer for performance, and (iv) the terms of any
agreement with any Sub-Servicer shall provide that the Administrator may
terminate such agreement upon the termination of the Servicer hereunder by
giving notice of its desire to terminate such agreement to the Servicer (and the
Servicer shall provide appropriate notice to each such Sub-Servicer); provided,
                                                                      --------
however, that if any such delegation is to any Person other than an Originator,

the Administrator shall have consented in writing in advance to such delegation.

     SECTION 4.2  Duties of the Servicer. (a) The Servicer shall take or cause
                  ----------------------
to be taken all such action as may be necessary or advisable to administer and
collect each Pool Receivable from time to time, all in accordance with this
Agreement and all applicable laws, rules and regulations, with reasonable care
and diligence, and in accordance with the Credit and Collection Policies. The
Servicer shall set aside, for the accounts of the Seller and the Issuer, the
amount of the Collections to which each is entitled in accordance with Article
                                                                       -------
I. The Servicer may, in accordance with the applicable Credit and Collection
-
Policies, extend the maturity of any Pool Receivable (but not beyond 30 days)
and extend the maturity or adjust the Outstanding Balance of any Defaulted
Receivable as the Servicer may determine to be appropriate to maximize
Collections thereof; provided, however, that: (i) such extension or adjustment
                     --------  -------
shall not alter the status of such Pool Receivable as a Delinquent Receivable or
a Defaulted Receivable or limit the rights of the Issuer or the Administrator
under this Agreement and (ii) if a Termination Event has occurred and IMCO or an
Affiliate thereof is serving as the Servicer, IMCO or such Affiliate may make
such extension or adjustment only upon the prior approval of the Administrator.
The Seller shall deliver to the Servicer and the Servicer shall hold for the
benefit of the Seller and the Administrator (individually and for the benefit of
the Issuer), in accordance with their respective interests, all records and
documents (including computer tapes or disks) with respect to each Pool
Receivable. Notwithstanding anything to the contrary contained herein, the
Administrator may direct the Servicer (whether the Servicer is IMCO or any other
Person) to commence or settle any legal action to enforce collection of any Pool
Receivable or to foreclose upon or repossess any Related Security, provided that
                                                                   --------
no such direction may be given unless a Termination Event or an Unmatured
Termination Event has occurred and is continuing.

          (b)  The Servicer shall, as soon as practicable following actual
receipt of collected funds, turn over to the Seller the collections of any
indebtedness that is not a Pool Receivable, less, if IMCO or an Affiliate
thereof is not the Servicer, all reasonable and appropriate out-of-pocket costs
and expenses of such Servicer of servicing, collecting and administering such
collections. The Servicer, if other than IMCO or an Affiliate thereof, shall, as
soon as practicable upon demand, deliver to the Seller all records in its
possession that evidence or relate to any indebtedness that is not a Pool
Receivable, and copies of records in its possession that evidence or relate to
any indebtedness that is a Pool Receivable.

<PAGE>

          (c)  The Servicer's obligations hereunder shall terminate on the later
of: (i) the Facility Termination Date and (ii) the date on which all amounts
required to be paid to the Issuer, the Administrator and any other Indemnified
Party or Affected Person hereunder shall have been paid in full.

After such termination, if IMCO or an Affiliate thereof was not the Servicer on
the date of such termination, the Servicer shall promptly deliver to the Seller
all books, records and related materials that the Seller previously provided to
the Servicer, or that have been obtained by the Servicer, in connection with
this Agreement.

     SECTION 4.3 Lock-Box Arrangements. On or prior to the initial purchase
                 ---------------------
hereunder, the Seller shall enter into Lock-Box Agreements with all of the Lock-
Box Banks and deliver original counterparts thereof to the Administrator. Upon
the occurrence of a Termination Event, the Administrator may at any time
thereafter give notice to each Lock-Box Bank that the Administrator is
exercising its rights under the Lock-Box Agreements to do any or all of the
following: (a) to have the exclusive ownership and control of the Lock-Box
Accounts transferred to the Administrator and to exercise exclusive dominion and
control over the funds deposited therein, (b) to have the proceeds that are sent
to the respective Lock-Box Accounts redirected pursuant to the Administrator's
instructions rather than deposited in the applicable Lock-Box Account, and (c)
to take any or all other actions permitted under the applicable Lock-Box
Agreement. The Seller hereby agrees that if the Administrator at any time takes
any action set forth in the preceding sentence, the Administrator shall have
exclusive control of the proceeds (including Collections) of all Pool
Receivables and the Seller hereby further agrees to take any other action that
the Administrator may reasonably request to transfer such control. Any proceeds
of Pool Receivables received by the Seller or the Servicer thereafter shall be
sent immediately to the Administrator. The parties hereto hereby acknowledge
that if at any time the Administrator takes control of any Lock-Box Account, the
Administrator shall not have any rights to the funds therein in excess of the
unpaid amounts due to the Administrator, the Issuer or any other Person
hereunder, and the Administrator shall promptly distribute or cause to be
distributed such funds in accordance with Section 4.2(b) and Article I (in each
                                          -------------      ---------
case as if such funds were held by the Servicer thereunder). The Seller hereby
agrees to take all actions necessary to ensure that all Lock-Box Accounts are
maintained in the name of the Servicer.

     SECTION 4.4 Enforcement Rights. (a) At any time following the occurrence
                 ------------------
of a Termination Event:

          (i)  the Administrator may direct the Obligors that payment of all
         amounts payable under any Pool Receivable is to be made directly to the
         Administrator or its designee,

          (ii) the Administrator may instruct the Seller or the Servicer to give
         notice of the Issuer's interest in Pool Receivables to each Obligor,
         which notice shall direct that payments be made directly to the
         Administrator or its designee, and the Seller or the Servicer, as the
         case may be, shall give such notice at the expense of the Seller or the
         Servicer, as the case

                                                  Receivables Purchase Agreement
<PAGE>

         may be; provided that if the Seller or the Servicer, as the case may
                 --------
         be, fails to so notify each Obligor, the Administrator (at the Seller's
         or the Servicer's, as the case may be, expense) may so notify the
         Obligors, and

               (iii) the Administrator may request the Servicer to, and upon
         such request the Servicer shall: (A) assemble all of the records
         necessary or desirable to collect the Pool Receivables and the Related
         Security, and transfer or license to a successor Servicer the use of
         all software necessary or desirable to collect the Pool Receivables and
         the Related Security, and make the same available to the Administrator
         or its designee at a place selected by the Administrator, and (B)
         segregate all cash, checks and other instruments received by it from
         time to time constituting Collections in a manner acceptable to the
         Administrator and, promptly upon receipt, remit all such cash, checks
         and instruments, duly endorsed or with duly executed instruments of
         transfer, to the Administrator or its designee.

               (b)   The Seller hereby authorizes the Administrator, and
irrevocably appoints the Administrator as its attorney-in-fact with full power
of substitution and with full authority in the place and stead of the Seller,
which appointment is coupled with an interest, to take any and all steps in the
name of the Seller and on behalf of the Seller necessary or desirable, in the
determination of the Administrator, to collect any and all amounts or portions
thereof due under any and all Pool Assets, including endorsing the name of the
Seller on checks and other instruments representing Collections and enforcing
such Pool Assets. The Administrator hereby agrees that it shall not exercise
such power or authority unless a Termination Event or an Unmatured Termination
Event has occurred and is continuing. Notwithstanding anything to the contrary
contained in this subsection, none of the powers conferred upon such attorney-
in-fact pursuant to the preceding sentence shall subject such attorney-in-fact
to any liability if any action taken by it shall prove to be inadequate or
invalid, nor shall they confer any obligations upon such attorney-in-fact in any
manner whatsoever.

         SECTION 4.5  Responsibilities of the Seller. (a) Anything herein to the
                      ------------------------------
contrary notwithstanding, the Seller shall: (i) perform all of its obligations,
if any, under the Contracts related to the Pool Receivables to the same extent
as if interests in such Pool Receivables had not been transferred hereunder, and
the exercise by the Administrator or the Issuer of their respective rights
hereunder shall not relieve the Seller from such obligations, and (ii) pay when
due any taxes, including any sales taxes payable in connection with the Pool
Receivables and their creation and satisfaction. The Administrator and the
Issuer shall not have any obligation or liability with respect to any Pool
Asset, nor shall either of them be obligated to perform any of the obligations
of the Seller, IMCO or an Originator thereunder.

               (b)    IMCO hereby irrevocably agrees that if at any time it

Purchaser or other Program Support Provider or any Person that is: (i) in the
business of issuing Notes and (ii) controlled or administered by PNC or any

institutions (each a "Purchaser") party to the Liquidity Agreement, or to any
                      ---------
other Program Support Provider, participating interests in the Purchased
Interest. In the event of any such grant by the Issuer of a participating
interest to a Purchaser or other Program Support Provider, the Issuer shall
remain responsible for the performance of its obligations hereunder. The Seller
agrees that each Purchaser or other Program Support Provider shall be entitled
to the benefits of Sections 1.7 and 1.8.

                                    --------------
the Servicer may assign its rights or delegate its obligations hereunder or any
interest herein without the prior written consent of the Administrator.

applicable law, the rights of the Issuer may be enforced through it or by its
agents.

                                 AMENDMENT TO
                     DEBTOR-IN-POSSESSION CREDIT AGREEMENT

                                August 16, 2000

          Reference is made to that certain Debtor-In-Possession Credit
Agreement dated as of September 13, 1999 (as heretofore amended, supplemented or
otherwise modified, the "DIP Credit Agreement"), by and among Vencor, Inc., a
Delaware corporation ("Vencor"), and Vencor Operating, Inc., a Delaware
corporation ("Vencor Opco"), each as debtor and debtor-in-possession, and each
of Vencor's subsidiaries listed on the signature pages thereof, each as debtor
and debtor-in-possession (each such subsidiary, Vencor and Vencor Opco
individually referred to herein as a "Borrower" and, collectively, on a joint
and several basis, as the "Borrowers"); the Lenders listed on the signature
pages thereof; and Morgan Guaranty Trust Company of New York, as arranger,
collateral agent and administrative agent (in such capacity, "Administrative
Agent") for the Lenders, and as an issuing bank for Letters of Credit
thereunder. Capitalized terms used herein without definition herein shall have
the meanings assigned to such terms in the DIP Credit Agreement.

          The Borrowers have requested that Lenders further extend the deadline
for filing a plan of reorganization acceptable to the Required Lenders in the
Chapter 11 Cases.  Accordingly, Borrowers and the undersigned Lenders hereby
agree that Section 5.10 of the DIP Credit Agreement is hereby amended by
deleting the reference to "August 17, 2000" contained therein and substituting
therefor "September 29, 2000".

          The Borrowers have further requested that Lenders amend the covenant
requiring the Borrowers to maintain at all times a Net Amount of Accounts
Receivable.  Accordingly, Borrowers and the undersigned Lenders hereby agree
that Section 6.04 of the DIP Credit Agreement is hereby amended by deleting the
reference to "$300,000,000" contained therein and substituting therefore
"$285,000,000".

          On and after the Amendment Effective Date (as defined below), each
reference in the DIP Credit Agreement to "this Agreement", "hereunder",
"hereof", "herein" or words of like import referring to the DIP Credit
Agreement, and each reference in the other Financing Documents to the "DIP
Credit Agreement", "thereunder", "thereof" or words of like import referring to
the DIP Credit Agreement, shall mean and be a reference to the DIP Credit
Agreement as amended by this Amendment to Debtor-In-Possession Credit Agreement
(this "Amendment"; the DIP Credit Agreement, as so amended, being the "Amended
Agreement").
<PAGE>

          Without limiting the generality of the provisions of Section 11.05 of
the DIP Credit Agreement, the amendments set forth in the paragraphs above shall
be limited precisely as written, and nothing in this Amendment shall be deemed
to prejudice any right or remedy that the Administrative Agent or any Lender may
now have or may have in the future under or in connection with the DIP Credit
Agreement or any of such other Financing Documents.  Except as specifically
amended by this Amendment, the DIP Credit Agreement and such other Financing
Documents shall remain in full force and effect and are hereby ratified and
confirmed.

          In order to induce Lenders to enter into this Amendment, each
Borrower, by its execution of a counterpart of this Amendment, represents and
warrants that (a) such Borrower has the corporate or other power and authority
and all material Governmental Approvals required to enter into this Amendment
and to carry out the transactions contemplated by, and perform its obligations
under, the Amended Agreement, (b) the execution and delivery of this Amendment
and the performance of the Amended Agreement have been duly authorized by all
necessary corporate or other action on the part of such Borrower, (c) the
execution and delivery by such Borrower of this Amendment and the performance by
such Borrower of the Amended Agreement do not and will not contravene, or
constitute a default under, any Applicable Laws (including an applicable order
of the Court) or any provision of its Organizational Documents, or of any
agreement or other instrument binding upon it or result in or require the
imposition of any Liens (other than the Liens created by the Collateral
Documents) on any of its assets, (d) the execution and delivery by such Borrower
of this Amendment and the performance by such Borrower of the Amended Agreement
do not and will not require any action by or in respect of, or filing with, any
governmental body, agency or official, (e) this Amendment and the Amended
Agreement have been duly executed and delivered by such Borrower and constitute
the valid and binding obligations of such Borrower, enforceable in accordance
with their respective terms, except as may be limited by general principles of
equity, (f) for purposes of the Borrowing Order (i) this Amendment constitutes a
non-material modification of the DIP Credit Agreement and the Financing
Documents, and (ii) notice of this Amendment has been given to and received by
counsel to the Committee (as defined in the Borrowing Order), and (g) after
giving effect to this Amendment, no event has occurred and is continuing or will
result from the consummation of the transactions contemplated by this Amendment
that would constitute a Default.

          This Amendment may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument.  This Amendment shall
become effective (the date of such effectiveness being the "Amendment Effective
Date") upon the earliest date on or prior to August 16, 2000 that (a) the
Borrowers and Required Lenders shall have executed counterparts of this
Amendment and the Borrowers and the Administrative Agent shall have received
written or telephonic notification of such execution and authorization of
delivery thereof; (b) the Administrative Agent shall have received evidence
satisfactory to it that all outstanding statements of O'Melveny & Myers LLP,
Davis Polk & Wardwell and Policano & Manzo that are received by Vencor prior to
12:00 Noon (New York City time) on August 11, 2000 have been paid in full; and
(c) no objections to this Amendment have been served on the Administrative Agent
by the Committee.

          Pursuant to paragraph 3 of the Borrowing Order, this Amendment shall
become effective upon the Amendment Effective Date without the need for any
further order of the Court

                                       2

and upon compliance with the notice requirement of paragraph 3 of the Borrowing
Order and the Committee having submitted no objection thereto.

          THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER
SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING WITHOUT LIMITATION SECTION
5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK), WITHOUT REGARD
TO CONFLICTS OF LAWS PRINCIPLES.
