     SECTION 1.2  Timing of Purchases and Contributions .
                  -------------------------------------- 

     (a)  Closing Date Purchases.  All of the Purchased Assets of the 
          ----------------------
Seller that existed at the closing of the Seller's business on the Initial Cut-
Off Date will be sold or (in accordance with the Subscription Agreement)
contributed automatically to ARC on the Closing Date.

     (b)  Regular Purchases and Contributions.  Except as otherwise provided in
          -----------------------------------

- - - -----------                                                                    
Date), each Receivable and the Related Assets with respect thereto shall be sold
by the Seller to ARC unless the Receivable and Related Assets with respect
thereto have been contributed by the Seller to ARC in accordance with the
Subscription Agreement.  The time at which each such sale and contribution
becomes effective shall be determined in accordance with the remaining
provisions of this Section 1.2.  During Phase II, until the Purchase Termination
                   -----------                                                  
Date and except as otherwise provided in Section 8.2, each Receivable shall be
                                         -----------                          
deemed to have been sold by the Seller to ARC immediately (and without further
action by any Person) upon the opening of business on the Determination Date for
such Receivable, unless the Receivable and Related Assets have been contributed
to ARC in accordance with the Subscription Agreement at such time.

     (c)  Determination Date Calculations.  No later than 11:00 a. m., New York
          -------------------------------                                      
City time, on each Determination Date during Phase I, the Servicer will
determine (which determination will be set forth in the Daily Report for such
Determination Date):



                                                                          page 2

 
               (i)    the aggregate Unpaid Balance of Receivables (the
          "Available Receivables") originated on each Origination Date occurring
          on or after the previous Business Day but prior to such Determination
          Date,

               (ii)   the Minimum Return for the Available Receivables,

               (iii)  the amount of the Cash Transfer (if any) that would be
          made on such day if the Available Receivables were sold by the Seller
          to ARC, and transferred by ARC to the Trust, on such day,

               (iv)   the net increase (if any) that would be made in the ARC
     Revolving Amount on such day if the Available Receivables were sold by
     the Seller to ARC, and transferred by ARC to the Trust, on such day,

               (v)    the "Transfer Value" for the Available Receivables, which
     shall be the sum of the amounts determined pursuant to clauses (iii)
                                                            -------------
     and (iv) above, and
         ----  

               (vi)   the excess (which may be a positive or negative number) of
     the Transfer Value of the Available Receivables over the Minimum
     Return for the Available Receivables; any such negative excess being
     the "Shortfall" for such Determination Date.

     (d)  Sale Timing if No Shortfall Exists.  If there is no Shortfall on such
          ----------------------------------                                   
Determination Date (and no Look Back Period is then in effect), the Available
Receivables will be sold by the Seller to ARC on that day, effective as of the
time the Trustee initiates a wire transfer of that day's Cash Transfer to ARC;
provided, that on any such Determination Date for which there is no Cash
Transfer, such sale by the Seller shall be effective upon the Trustee's receipt
of the Daily Report for such day.

     (e)  Sale Timing if a Shortfall Exists.  If a Shortfall shall exist 
          ---------------------------------
on such Determination Date: 
               (i) the Servicer shall, no later than 11:00 a.m., New York time,
          on the Determination Date, notify the Trustee and the Seller Agent by
          telephone (to be promptly confirmed by telecopy),

               (ii) the Seller shall deliver to the Seller Agent, no later
          than 11:15 a.m., New York time, on the Determination Date, a
          certificate in the form attached as Exhibit B (the "AmeriSource
          Certificate") signed by a senior officer of AmeriSource identified
          pursuant to the Original Seller Credit Agreement as being acceptable
          to the Seller Agent for such purpose that (A) specifies whether an
          Event of Default or an Unmatured Event of Default then exists (and, if
          such an event exists, describing such event in detail), and (B) sets
          forth the End-of-the-Day Seller Excess Borrowing Base


                                                                          page 3

 
          for such day, as well as the calculation thereof. The AmeriSource
          Certificate may provide that the End-of-the-Day Seller Excess
          Borrowing Base has been calculated on the basis of the most recently
          required Borrowing Base Certificate under the Original Seller Credit
          Agreement, but in that event the AmeriSource Certificate shall also
          include a representation and warranty by AmeriSource to Seller Agent
          and each Seller Party that AmeriSource has no reason to believe that
          the End-of-the-Day Seller Excess Borrowing Base set forth therein
          would be any lower than $40,000,000 if calculated on the basis of a
          new Borrowing Base Certificate delivered under the Original Seller
          Credit Agreement as of the Determination Date.

               (iii)  a period (the "Look Back Period") will commence; it being
          understood that the Look Back Period will end on the date the Trustee
          receives or is deemed to receive a Stop Date Notice or a Confirmation
          Notice, and

               (iv)   the Affected Receivables will not be sold by the Seller to
          ARC, or transferred by ARC to the Trust, unless and until the Trustee
          receives or is deemed to receive a Confirmation Notice.

          (f)  Deemed Confirmation Notice.  If on the basis of the AmeriSource
          --------------------------                                     
Certificate the End-of-the-Day Seller Excess Borrowing Base equals or exceeds
$40,000,000, the Seller shall notify the Trustee and the Servicer as soon as
practical in writing.  Such notice shall be deemed to constitute a Confirmation
Notice from the Seller Agent to the Trustee and the Servicer.

          (g)  Additional Look Back Period Calculations. On each Business Day
          ---------------------------------------- 
(other than the first Determination Date) falling in a Look Back Period, the
mechanics described in clauses 1.2(c) through 1.2(f) will be repeated, with the
             --------------         ------                           
modifications that (i) all calculations (including calculations of the permitted
Cash Transfer, the Transfer Value, the Shortfall and the End-of-the-Day Excess
Borrowing Base) shall be made on a cumulative basis, as if all of the days in
the Look Back Period were a single day, (ii) references to "Available
Receivables" shall be deemed to be references to all Affected Receivables
arising during the Look Back Period, (iii) references to the Determination Date
will be deemed to be references to the day on which such mechanics are
performed, (iv) Segregated Cash shall be recomputed on the basis of such day's
Daily Reports, and (v) no additional Look Back Period will commence, and instead
the existing Look Back Period will continue.  If, on any such day, there is no
Shortfall on such a cumulative basis or, on the basis of the AmeriSource
Certificate, the End-of-the-Day Seller Excess Borrowing Base equals or exceeds
$40,000,000, then the Seller shall notify the Trustee and the Servicer in
writing, and the Servicer shall cause Segregated Cash in an amount not less than
the amount assumed to be received by the Seller Agent for purposes of the
calculation of the End-of-the-Day Seller Excess Borrowing Base to be transferred
by the Trust to ARC on such day.  Such notice from the Seller to the Trustee and
the Servicer shall be deemed to constitute a Confirmation Notice from the Seller
Agent to the Trustee and the Servicer.


                                                                          page 4

 
     (h)  Effect of Confirmation Notice. If the Trustee receives a
          -----------------------------   
Confirmation Notice by 2:00 p. m., New York City time, on any Business Day
(including the Determination Date) during the Look Back Period, the Affected
Receivables shall be sold by the Seller to ARC on such day. If the Trustee
receives a Confirmation Notice on a day which is not a Business Day, or after
2:00 P.M., New York City time, on a Business Day, the Affected Receivables shall
be sold by the Seller to ARC on the next Business Day. Any such sales shall be
effective as of the time the Trustee initiates a wire transfer of an amount
equal to the Segregated Cash (including that day's Cash Transfer) to ARC;
provided, that if the amount of such Segregated Cash is zero, such sale by the
Seller shall be effective upon the Trustee's receipt of the Confirmation Notice.

     (i)  Deemed Stop Date Notice. If the Seller Agent has not delivered 
          -----------------------
(or been deemed to deliver) either a Stop Date Notice or a Confirmation Notice
to the Trustee by 11:15 a.m., New York time, on the 5th Business Day after the
Determination Date in any Look Back Period, the Seller Agent shall be deemed to
have given a Stop Date Notice on such day.

     (j)  Trustee Reliance. The Trustee shall be entitled to rely
          ----------------           
exclusively on the Servicer's determination of whether a Shortfall exists or the
conditions specified in Section 1.2(f) or 1.2(g) exist, and such determination
                        --------------    ------            
shall be binding on all parties to the Transaction Documents.

     SECTION 1.3  Consideration for Purchases .  On the terms and subject to the
                  ----------------------------                                  
conditions set forth in this Agreement, ARC agrees to make Purchase Price
payments to the Seller in accordance with Article III.
                                          ----------- 

     SECTION 1.4  No Recourse .  Except as specifically provided in this
                  ------------                                          
Agreement, the sale and purchase of Purchased Assets under this Agreement shall
be without recourse to the Seller; it being understood that the Seller shall be
liable to ARC for all representations, warranties, covenants and indemnities
made by the Seller pursuant to the terms of this Agreement, all of which
obligations are limited so as not to constitute recourse to the Seller for the
credit risk of the Obligors.

     SECTION 1.5  No Assumption of Obligations Relating to Receivables, Related
                  -------------------------------------------------------------
Assets or Contracts .  Neither ARC, the Servicer nor the Trustee shall have any
- - - -------------------                                                           
obligation or liability to any Obligor or other customer or client of the Seller
(including any obligation to perform any of the obligations of the Seller under
any Receivable, related Contracts or any other related purchase orders or other
agreements).  No such obligation or liability is intended to be assumed by ARC,
the Servicer or the Trustee hereunder, and any assumption is expressly
disclaimed.

purpose to be characterized as, loans from ARC to the Seller.

     SECTION 1.7  Addition of Sellers .  Any Subsidiary or Affiliate of the 
                  --------------------                                      
Seller may become a Seller hereunder and sell its accounts receivable and
property of the types that constitute Related Assets hereunder to ARC if the
Rating Agency Condition is satisfied with respect to such addition. The Seller
and its Subsidiary or Affiliate that is proposed to be added as a Seller shall
give to ARC and the Applicable Rating Agencies not less than 30 days' prior
written notice of the effective date of the addition of the Subsidiary or
Affiliate as a Seller. Once the notice has been given, any addition of a
Subsidiary or Affiliate of the Seller as a Seller pursuant to this section shall
become effective on the first Business Day following the expiration of the 30-
day period (or such later date as may be specified in the notice) on which (i)
the Rating Agency Condition has been satisfied, (ii) the Seller has given the
notice described in Section 3.05(e) of the Pooling Agreement to ARC, (iii) the

                  ----------------------------------               
more than one Person is a Seller, a Seller may terminate its obligation to sell
its Receivables and Related Assets to ARC if:

          (i)   the Seller (a "Terminating Seller") shall have given ARC
     not less than 30 days' prior written notice of its intention to terminate
     the obligations, which notice shall be given by ARC to the Trustee and the
     Applicable Rating Agencies,

          (ii)  an Authorized Officer of the Terminating Seller shall have
     certified that the termination by the Terminating Seller of its status as a
     Seller will not have a Material Adverse Effect, and

          (iii) both immediately before and after giving effect to the
     termination by the Terminating Seller, no Liquidation Event or Unmatured
     Liquidation Event or Pay-Out Event shall have occurred and be continuing or
     shall reasonably be expected to occur.

     Any termination by a Seller shall become effective on the first Business
Day that follows the day on which the requirements of clauses (a)(i) through 
                                                      --------------      
(iii) shall have been satisfied (or such later date specified in the notice or

certificate referred to in the clauses).  Any termination by a Seller shall
terminate its right and obligation to sell Receivables and Related Assets
hereunder to ARC and ARC's agreement, with respect to the Terminating Seller, to
purchase the Receivables and Related Assets; provided, however, that the


                                                                          page 6

 
termination shall not relieve the Terminating Seller of any of its other
Obligations, to the extent the Obligations relate to Receivables (and Related
Assets with respect thereto) originated by the Terminating Seller prior to the
effective date of the termination.

     (b)  A Seller's right and obligation to sell its Receivables and Related
Assets to ARC shall terminate immediately if the Seller ceases to be a
Subsidiary of the Seller; provided, however, that the termination shall not
relieve the Seller of any of its other Obligations, to the extent the
Obligations relate to Receivables (and Related Assets with respect thereto)
originated by the Seller prior to the effective date of the termination.

the Seller:

         (i)  that are to be made on the Closing Date (in the case of the Daily
     Report to be delivered on the Closing Date) or

         (ii)  that were made on the immediately preceding Business Day (in the
     case of each subsequent Daily Report).

     (b)  On each day when Receivables or Notes Receivable are purchased by ARC
from the Seller pursuant to Article I, the "Purchase Price" to be paid to the
                            ---------                                        
Seller on such day for the Purchased Receivables and Related Purchased Assets
that are to be sold by the Seller on such day shall be determined in accordance
with the following formula:

     PP   =    AUB x PPP

     where:

     PP   =    the aggregate Purchase Price for the Purchased Receivables and
               Related Purchased Assets to be purchased from the Seller on such
               day

     AUB       the "Aggregate Unpaid Balance" of the Purchased Receivables that
               are to be purchased from the Seller on such day. For purposes of
               this calculation, "Aggregate Unpaid Balance" shall mean (i) for
               purposes of calculating the Purchase Price to be paid to the
               Seller on the Closing Date, the sum of the Unpaid Balance of each
               Receivable generated by the Seller, as measured as at the closing
               of the Seller's business on the


                                                                          page 7

 
               Initial Cut-Off Date, and (ii) for purposes of calculating the
               Purchase Price on each Business Day thereafter, the sum of the
               Unpaid Balance of each Receivable to be purchased from the Seller
               on such day, calculated at the time of the Receivable's sale to
               ARC

     PPP  =    the Purchase Price Percentage applicable to the Receivables to be
               purchased from the Seller on such day, as determined pursuant to
               Section 2.2.

                  Percentage .
                  ----------- 

     (a)  "Purchase Price Percentage" for the Receivables to be sold by the
Seller on any day shall mean the percentage determined in accordance with the
following formula:
 
     PPP  =    100% - (LD + PDRR + RGP)
 
     where:
 
     PPP  =    the Purchase Price Percentage in effect on such day for the 
               Seller,
 
     LD   =    the Loss Discount (expressed as a percentage) in effect on such
               day for the Seller, as determined pursuant to subsection (b)
                                                             --------------
               below,

     PDRR =    the Purchase Discount Reserve Ratio (expressed as a percentage)
               in effect on such day for the Seller, as determined on such day
               pursuant to subsection (c) below, and
                           --------------

     RGP  =    the Returned Goods Percentage.

The Purchase Price Percentage, the Loss Discount and the Purchase Discount
Reserve Ratio shall be recomputed by the Servicer on each Report Date, in each
case as of the then most recent Cut-Off Date, and shall become effective on the
next Settlement Date.

     (b)  "Loss Discount" in effect for any day for the Seller means a 
percentage equal to the Loss to Liquidation Ratio (expressed as a percentage) as
in effect on such day (it being understood that the allocation of certain
miscellaneous items will be required to be estimated for this purpose).

     (c)  "Purchase Discount Reserve Ratio" for the Receivables to be sold by 
the Seller on any day shall mean a percentage determined in accordance with the
following formula:
 
     PDRR =    (TD  x DR)  +  PD
                --                
                360

     where:
 
     PDRR =    the Purchase Discount Reserve Ratio in effect on such day for the
               Seller,
 
     TD   =    the Turnover Days for the Receivables originated by the Seller
               during the immediately preceding Calculation Period,

     DR   =    the Discount Rate (expressed as a percentage) in effect on such
               day as determined pursuant to subsection (d) below, and

     PD   =    a profit discount equal to 0.25%.



     (d)  "Discount Rate" for the Receivables to be sold by the Seller on any 
day shall mean a fraction (expressed as a percentage) having (i) a numerator
equal to 12, multiplied by an amount equal to the accrued Carrying Costs for the
immediately preceding Calculation Period, and (ii) a denominator equal to the
aggregate Unpaid Balance of the Receivables as of the last day of the
immediately preceding Calculation Period.


                                  ARTICLE III
                  PAYMENT OF PURCHASE PRICE; SERVICING, ETC.


     SECTION 3.1  Purchase Price Payments.  (a)  On the Closing Date and on the
                  -----------------------                                    
Business Day following each day on which any Receivables are purchased (or
deemed purchased) from the Seller by ARC pursuant to Article I, on the terms and
                                                     ---------                  
subject to the conditions of this Agreement, ARC shall pay to the Seller the
Purchase Price for the Receivables and Related Assets purchased on such day by
ARC from the Seller by (i) making a cash payment (on the basis of the Purchase
Price owing to the Seller) to the Seller to the extent that ARC has cash
available to make the payment pursuant to Section 3.3 and (ii) if the Purchase
                                          -----------                         
Price to be paid to the Seller for the Receivables and Related Assets exceeds
the amount of any cash payment on such day to the Seller pursuant to clause (i),
                                                                     ---------- 
by automatically increasing the principal amount outstanding under the ARC Note
by the amount of the excess.  In addition, on any Business Day ARC may prepay
the Purchase Price to be paid to the Seller for Receivables and Related Assets
generated on a subsequent Business Day.  For purposes of the remaining
provisions of this section, the Purchase Price otherwise payable on any day by
ARC to the Seller shall be deemed to be reduced by cumulative unused amount of
such prepayments.

     (b)  On each Business Day, the "Noncomplying Receivables and Dilution
Adjustment" shall be equal to the difference (whether the difference is positive
or negative) between (i) the sum of (A) the Seller Dilution Adjustment, if any,
for the immediately preceding 


                                                                          page 9

 
Business Day, as shown in the Daily Report for such day, plus (B) the Seller
Noncomplying Receivables Adjustment, if any, for the immediately preceding
Business Day, as shown in the Daily Report for such day, in the case of each of
clauses (A) and (B), as the amounts are determined pursuant to Section 3.5, 
- - - -----------     ---                                            -----------
minus (ii) the amount of any payments (if any) that ARC shall have received on
the immediately preceding Business Day on account of a Seller Noncomplying
Receivable that has been the subject of an earlier Seller Noncomplying
Receivables Adjustment. If the Noncomplying Receivables and Dilution Adjustment
is positive on any day, ARC shall reduce the Purchase Price payable to the
Seller on such day by the absolute value of the Noncomplying Receivables and
Dilution Adjustment. If instead the Noncomplying Receivables and Dilution
Adjustment for the Seller is negative on any day, ARC shall increase the
Purchase Price payable to the Seller on suc h day by the absolute value of the
Noncomplying Receivables and Dilution Adjustment.

     (c)  If a positive Noncomplying Receivables and Dilution Adjustment for the
Seller on any day exceeds the Purchase Price payable by ARC to the Seller on
such day, or if such day falls on or after the Purchase Termination Date, then,
if the Seller continues to hold the ARC Note, the principal amount of that ARC
Note shall be reduced automatically by the amount of the excess.

     (d)  If, on any day prior to the Purchase Termination Date, the principal
amount of the ARC Note is zero, then the amount of the excess of a positive
Noncomplying Receivables and Dilution Adjustment for the Seller on such day over
the Purchase Price payable by ARC to the Seller on such day (the "Purchase Price
Credit") shall be credited against the Purchase Price payable by ARC to the
Seller for subsequent Purchases of Receivables and Related Assets by ARC.  If
any Purchase Price Credit for the Seller has not been fully applied on or prior
to the tenth Business Day (or mutually agreed upon earlier day) after the
creation of the Purchase Price Credit, then, on the Business Day that follows
the end of the ten Business Day (or shorter) period, the Seller shall pay to ARC
in cash the remaining unapplied amount of the Purchase Price Credit.

     (e)  If, on any day on or after the Purchase Termination Date, the 
principal amount of the ARC Note has been reduced to zero and there is a
positive Noncomplying Receivables and Dilution Adjustment for the Seller for
such day, then the Seller shall pay to ARC in cash the amount of the
Noncomplying Receivables and Dilution Adjustment on the next succeeding Business
Day.

     (f)  If, on any day on or after the Purchase Termination Date, there is a
negative Noncomplying Receivables and Dilution Adjustment for the Seller for
such day, then ARC shall pay to the Seller in cash the amount of the
Noncomplying Receivables and Dilution Adjustment no later than the Final
Maturity Date, and the amount, until paid, shall bear interest at the rate of
interest publicly announced from time to time by the Trustee as its reference
rate, which interest shall also be paid no later than the Final Maturity Date.


                                                                         page 10

 
     SECTION 3.2  The ARC Note .  (a)  On the Closing Date, ARC will deliver to
                  -------------                   
the Seller a promissory note, substantially in the form of Exhibit A, payable
                                                            ---------
to the order of the Seller (the promissory note, as the same may be amended,
supplemented, endorsed or otherwise modified from time to time, together with
any promissory note issued from time to time in substitution therefor or renewal
thereof in accordance with the Transaction Documents, being herein called the
"ARC Note"), that is subordinated to all Senior Interests now or hereafter
arising under or in connection with the Pooling Agreement.  The ARC Note is
payable in full on the date that is twelve months after the date on which all
Investor Certificates and Purchased Interests have been repaid in full and the
Revolving Periods for all Investor Revolving Certificates and Purchased
Interests have terminated.  The ARC Note bears interest at a rate per annum
equal to the rate publicly announced by the Trustee  from time to time as its
"reference" rate, determined as of each Cut-Off Date.  ARC may prepay all or
part of the outstanding balance of the ARC Note from time to time without any
premium or penalty, unless the prepayment would result in a default in ARC's
payment of any other amount required to be paid by it under any Transaction
Document; provided, however, that no Liquidation Event or Unmatured Liquidation
Event has occurred.

     (b)  The Seller (or its designee) shall hold the ARC Note for the 
benefit of the Seller and shall make all appropriate recordkeeping entries with
respect to the ARC Note or otherwise to reflect the payments on and adjustments
of the ARC Note. The Servicer's books and records shall constitute rebuttable
presumptive evidence of the principal amount of and accrued interest on the ARC
Note at any time. The Seller hereby irrevocably authorizes the Servicer to mark
the ARC Note "CANCELLED" and return it to ARC upon the final payment thereof.

     SECTION 3.3  Application of Collections and Other Funds.  If, on any day,
                  ------------------------------------------
ARC receives proceeds of transfers pursuant to the Pooling Agreement, ARC shall
apply the funds as follows:

         (a)  first, to pay its existing expenses and to set aside funds for the
     payment of expenses that are then accrued (in each case to the extent such
     expenses are permitted to exist under Section 7.02(m) of the Pooling 
                                           --------------- 
     Agreement).
         (b)  second, to pay the Purchase Price pursuant to Section 3.1 for
                                                            -----------    
     Receivables and Related Assets purchased by ARC from the Seller on such day
     (in the case of the Closing Date) or the next preceding Business Day, and

         (c)  third, in such order as ARC may elect, (A) to repay amounts owed
     by ARC to the Seller under the ARC Note, provided, however, that no
     Liquidation Event or Unmatured Liquidation Event has occurred,(B) to pay
     amounts owed pursuant to Section 3.1(f), or (C) to declare and pay
                              --------------
     dividends to the Seller to the extent permitted by law, so long as ARC
     shall be in compliance with Section 7.02(o) of the Pooling Agreement after
     giving effect to the dividends.


                                                                         page 11

 
     SECTION 3.4  Servicing of Receivables and Related Assets .  Consistent with
                  --------------------------------------------                  
ARC's ownership of the Receivables and the Related Assets, as between the
parties to this Agreement, ARC shall have the sole right to service, administer
and collect the Receivables, to assign the right and to delegate the right to
others.  Without limiting the generality of Section 10.11, the Seller hereby
                                            -------------                   
acknowledges and agrees that ARC shall assign to the Trustee for the benefit of
the Certificateholders the rights and interests granted by the Seller to ARC
hereunder and agrees to cooperate fully with the Servicer and the Trustee in the
exercise of the rights.  As more fully described in Section 7.4(b) and in the
                                                    --------------           
Pooling Agreement, the Trustee may exercise the rights in the place of ARC (as
assignee or otherwise) only after the designation of a Servicer other than the
Seller pursuant to Section 10.02 of the Pooling Agreement.

Seller shall determine that any Receivable identified by the Servicer as an
Eligible Receivable on the date of Purchase thereof by ARC or the contribution
thereof to ARC was in fact a Seller Noncomplying Receivable on such date, or
that any of the representations and warranties made by the Seller in Section
                                                                     -------
5.1(k) with respect to the Receivable was not true on such date, the Seller

shall be deemed to have received on the date of such determination a Collection
of the Receivable in an amount equal to the Unpaid Balance of the Receivable
(the sum of all such amounts for the Seller on any day being called the "Seller
Noncomplying Receivables Adjustment" for the Seller for such day), and the
Seller shall pay the amount of the Seller Noncomplying Receivables Adjustment to
ARC in the manner provided for in Section 3.1.

     (b)  If on any day the aggregate Unpaid Balance of the Receivables sold or
contributed to ARC on or before such date by the Seller is reduced in any manner
described in the definition of "Dilution" or on account of any Cash Discounts
(the total of the reductions being called the "Seller Dilution Adjustment" for
the Seller for such day), then the Seller shall be deemed to have received on
such day a Collection of Receivables in the amount of the Seller Dilution
Adjustment and the Seller shall pay the amount to ARC in the manner provided in
Section 3.1.
- - - ----------- 

     SECTION 3.6  Payments and Computations, Etc .  (a)  All amounts to be paid
                   -------------------------------                  
by the Seller to ARC hereunder shall be paid in accordance with the terms hereof
no later than 2:00 p. m., New York City time, on the day when due in Dollars in
immediately available funds to an account that ARC shall from time to time
specify in writing. Payments received by ARC after such time shall be deemed to
have been received on the next Business Day. In the event that any payment
becomes due on a day that is not a Business Day, then the payment shall be made
on the next Business Day. The Seller shall, to the extent permitted by law, pay
to ARC, on demand, interest on all amounts not paid when due hereunder at 2% per
annum above the interest rate on the ARC Note in effect on the date the payment
was due; provided, however, that the interest rate shall not at any time exceed
the maximum rate


                                                                         page 12

 
permitted by applicable law. All computations of interest payable hereunder
shall be made on the basis of a year of 360 days for the actual number of days
(including the first but excluding the last day) elapsed.

     (b)  All amounts to be paid by ARC to the Seller hereunder shall be paid no
later than 2:00 p. m., New York City time, on the day when due in Dollars in
immediately available funds to an account that the Seller shall from time to

     except where the failure to obtain or make any such authorization, consent,
     order, approval, notice or filing, individually or in the aggregate for all

its prior written consent, the Seller hereby agrees that it will perform the
covenants and agreements set forth in this section.

          (a)  Compliance with Laws, Etc.  The Seller will comply in all 
               --------------------------

               -----------------------------------
     and maintain its corporate existence, rights, franchises and privileges in
     the jurisdiction of its incorporation, and qualify and remain qualified in
     good standing as a foreign corporation in each jurisdiction where the
     failure to preserve and maintain such existence, rights, franchises,
     privileges and qualifications would have a substantial likelihood of having
     a Material Adverse Effect.

          (c)  Receivables Reviews.  The Seller shall, during regular business

     (or its agent or representative) shall give the Seller at least five
     Business Days' prior notice of any Seller Receivables Review, and ARC shall
     have the right to request a Seller Receivables Review not more than twice

                                                                         page 21

 
          (d)  Keeping of Records and Books of Account.  The Seller shall 
               ---------------------------------------

     an ability to recreate records evidencing its Receivables and Related
     Assets in the event of the destruction of the originals thereof), and shall
     keep and maintain all documents, books, records and other information that,
     in the reasonable determination of ARC and the Trustee, are necessary or
     advisable in accordance with prudent industry practice and custom for
     transactions of this type for the collection of all Receivables and the
     Related Assets. Upon the reasonable request of ARC made at any time after
     the occurrence and continuance of a Servicer Default, the Seller will

     (i) all payments received and all credits and extensions granted with
     respect to the Receivables and (ii) the return, rejection, repossession, or
     stoppage in transit of any merchandise, the sale of which has given rise to
     a Receivable that has been purchased by ARC.


          (e)  Performance and Compliance with Receivables and Contracts.  The 
               ---------------------------------------------------------
     Seller will, at its expense, timely and fully perform and comply with all
     provisions, covenants and other promises required to be observed by it
     under the Contracts of the Seller related to the Receivables and Related
     Assets, the breach of which provisions, covenants or promises would have a
     substantial likelihood of having a Material Adverse Effect.

          (f)  Location of Records and Offices.  The Seller will keep its 
               -------------------------------                            
     principal place of business and chief executive office, and the offices
     where it keeps all Records related to the Receivables and the Related
     Assets (and all original documents relating thereto), at the addresses
     referred to in Schedule 2 or, upon not less than 30 days' prior written
                    ----------
     notice given by the Seller to ARC, the Trustee and the Applicable Rating
     Agencies, at such other locations in jurisdictions where all action
     required by Section 7.3 shall have been taken and completed.

     material respects with its Credit and Collection Policy in regard to each
     Receivable of the Seller and the Related Assets and the Contracts related
     to each such Receivable, where the failure so to comply, individually or in
     the aggregate for all such failures, would have a substantial likelihood of
     having a Material Adverse Effect.

          (h)  Separate Corporate Existence of ARC.  The Seller hereby 
               -----------------------------------   
     acknowledges that the Trustee, on behalf of the Trust, is entering into the
     transactions contemplated by the Transaction Documents in reliance upon
     ARC's identity as a legal entity 


                                                                         page 22

 
     separate from the Seller and the other AmeriSource Persons. Therefore, from
     and after the date hereof until the first day following the Purchase
     Termination Date on which all Obligations of the Seller shall have been
     fully paid and performed and the Investor Invested Amount shall have been
     reduced to zero, the Seller will, and will cause each other AmeriSource
     Person to, take all reasonable steps to continue their respective
     identities as separate legal entities and to make it apparent to third
     Persons that each is an entity with assets and liabilities distinct from
     those of ARC and that ARC is not a division of the Servicer, the Seller or
     any other Person.

          (i)  Payment Instructions to Obligors.  The Seller will instruct all
               --------------------------------   
     Obligors to submit all payments either (i) to one of the lockboxes
     maintained at the Lockbox Banks for deposit in a Lockbox Account or to a
     Concentration Account or (ii) directly to one of the Lockbox Accounts;
     except to the extent otherwise permitted under Section 5.1(o).
                                                    -------------- 
          (j)  Segregation of Collections.  The Seller shall use reasonable 
                -------------------------- 
     efforts to minimize the deposit of any funds other than Collections into
     any of the Lockbox Accounts and, to the extent that any such funds
     nevertheless are deposited into any of the Lockbox Accounts, shall promptly
     identify any such funds, or shall cause the funds to be so identified, to
     ARC, the Servicer and the Trustee (following which notice, ARC shall cause
     the Servicer to return all the funds to the Seller).

          (k)  Identification of Eligible Receivables.  The Seller will (i) 
               --------------------------------------
     establish and maintain such procedures as are necessary for determining no
     less frequently than each Business Day whether each Receivable qualifies as
     an Eligible Receivable, and for identifying, on any Business Day, all
     Receivables to be sold on that date that are not Eligible Receivables, and
     (ii) except as permitted in Section 3.05(c) of the Pooling Agreement,
     notify ARC prior to the occurrence of a Purchase if a Receivable to be sold
     hereunder will, to the Seller's knowledge, not be an Eligible Receivable as
     of the date of Purchase.

          (l)  Accuracy of Information.  All written information furnished on 
               -----------------------                                        
     and after the Closing Date by the Seller or any other AmeriSource Person to
     ARC, the Servicer or the Trustee pursuant to or in connection with any
     Transaction Document or any transaction contemplated herein or therein
     shall not contain any untrue statement of a material fact or omit to state
     material facts necessary to make the statements made not misleading, in
     each case on the date the statement was made and in light of the
     circumstances under which the statements were made or the information was
     furnished.

          (m)  Taxes.  File or cause to be filed, and cause each Person with 
               -----                                                         
     whom it shares consolidated tax liability to file, all Federal, state and
     local tax returns that are required to be filed by it, except where the
     failure to file such returns could not 



                                                                         page 23

 
     reasonably be expected to have an adverse effect, and pay or cause to be
     paid all taxes shown to be due and payable on taxes or assessments, the
     validity of which are being contested in good faith by appropriate
     proceedings and with respect to which the Seller shall have set aside
     adequate reserves on its books in accordance with GAAP and which
     proceedings could not reasonably be expected to have a Material Adverse
     Effect.

     account), within three Business Days after receipt thereof, any Collections
     that it receives, in the form so received, and agrees that all such
     Collections shall be deemed to be received in trust for ARC and shall be
     maintained and segregated separate and apart from all other funds and
     moneys of the Seller until delivery of such Collections to the Servicer.

          (b)  The Seller shall perform all of its obligations hereunder and

     connection herewith shall not relieve the 


                                                                         page 28

     require with regard to all services and computer hardware or software used
     by the Seller that relate to the servicing of the Transferred Assets.

     SECTION 7.3 Further Action Evidencing Purchases .  The Seller agrees that
                 -----------------------------------

purchase or contribution of the Receivables and the Related Assets or to enable

     amendments thereto or assignments thereof, and such other instruments or

thereof, relative to all or any of the Receivables and Related Assets of the
Seller, in each case whether now existing or hereafter generated by the Seller.

of its agreements or obligations under this Agreement and does not remedy the
failure within the applicable cure period, if any, and (ii) ARC in good faith
reasonably believes that the performance of such agreements and obligations is
necessary or appropriate to protect its interests under this Agreement, then ARC

designee or assignee incurred in connection with such performance shall be
payable by the Seller as provided in Section 9.1.

                 ----------------------------------------------------------     
(a) The Seller hereby transfers to the Trustee (as transferee of ARC's interest
in the Transferred Assets) the ownership of, and the exclusive dominion and
control over, each of the Bank Accounts and all related lockboxes owned by the
Seller, and the Seller hereby agrees to take any further action that ARC or the
Trustee may reasonably request in order to effect or complete the transfer. The
Seller further agrees to use reasonable efforts to prevent funds other than
proceeds of the Transferred Assets from being deposited in any Bank Account.

     (b)  ARC may, at any time after a Liquidation Event or Servicer
Default, direct the Obligors of Receivables, or any of them, to pay all amounts
payable under any Transferred Asset directly to the Trustee or its designees.
Furthermore, the Seller shall, at the request of ARC and at the Seller's
expense, promptly give notice of the Trust's interest in the Receivables of the
Obligor and the Related Assets to each such Obligor and direct that payments be
made directly to the Trustee or its designee, which notice shall be acceptable
in form and substance to ARC. In addition, the Seller hereby authorizes ARC to
take any and all steps in the Seller's name and on its behalf that are necessary
or desirable, in the reasonable determination of ARC, to collect all amounts due
under any and all Transferred Assets, including endorsing the Seller's name on
checks and other instruments representing Collections and enforcing the
Transferred Assets and the Contracts related to the Receivables. The Trustee may
exercise any of the foregoing rights in the place of ARC (as 


                                                                         page 30

 
assignee or otherwise) at any time following the designation of a Servicer
other than the Seller pursuant to Section 10.02 of the Pooling Agreement.

     (c) At any time when (i) a Liquidation Event shall have occurred and
remain continuing or (ii) a Servicer other than the Seller has been designated
pursuant to Section 10.02 of the Pooling Agreement, the Seller shall, at ARC's
request, assemble all of the Records that evidence the Receivables and Related
Assets originated by the Seller and the Contracts related to the Receivables, or
that are otherwise necessary or desirable to collect the Receivables or Related
Assets, and make the same available to ARC or the Trustee at a place selected by
the Trustee or its designee.

Commencement Date, the Seller may terminate its agreement to sell Receivables
hereunder to ARC by giving ARC and the Trustee not less than five Business Days'
prior written notice of its election not to continue to sell Receivables to ARC.
The Trustee shall notify the Certificateholders of all Series within five
Business Days of receiving any notice.  Upon receipt of a termination notice
from the Seller, ARC shall notify the holders of each Series of Fixed Principal
Certificates that it is electing to cause that Series to be prepaid in full and
shall cause each Series of Investor Revolving Certificates and Purchased
Interests to be repaid as early as is practicable.  The sale of Receivables
under this Agreement will not cease until all prepayments and repayments have
been completed.

     SECTION 8.2  Automatic Termination.  The agreement of the Seller to sell
                  ---------------------
Receivables hereunder, and the agreement of ARC to purchase Receivables from the
Seller hereunder, shall terminate automatically upon the Liquidation
Commencement Date (including without limitation a Liquidation Commencement Date
resulting from the Trustee's receipt of a Stop Date Notice); provided, however,
that if, at any time prior to the Liquidation Commencement Date, an Event of
Bankruptcy occurs as a result of a bankruptcy proceeding being filed against the
Seller, then on and after the date on which such bankruptcy proceeding is filed
until the dismissal of the proceeding ARC shall not purchase Receivables and
Related Purchased Assets from the Seller.

     SECTION 9.1 Indemnities by the Seller.  Without limiting any other rights
                 -------------------------
that any RPA Indemnified Party (as defined below) may have hereunder or under
applicable law, the Seller agrees to indemnify ARC, each of its successors,
permitted transferees and assigns, and all officers, directors, shareholders,
controlling Persons, employees and agents of any of the foregoing (each of the
foregoing Persons being individually called a "RPA Indemnified Party"),
forthwith on demand, from and against any and all damages, losses, claims
(whether on account of settlements or otherwise), judgments, liabilities and
related reasonable costs and expenses (including reasonable attorneys' fees and
disbursements) awarded against or incurred by any of them arising out of or as a
result of any of the following (all of the foregoing being collectively called
"RPA Indemnified Losses"):

          (a)  any representation or warranty made in writing by the Seller (or
     any of its Authorized Officers) under any of the Transaction Documents, any
     Settlement Statement, any Daily Report or any other information or report
     delivered by the Seller or the Servicer with respect to the Seller or the
     Receivables or Related Assets originated by the Seller, that contained any
     untrue statement of a material fact or omitted to state material facts
     necessary to make the statements not misleading when made,

          (b)  the failure by the Seller to comply with any applicable law, rule
     or regulation with respect to any Receivable or any Related Asset or to
     comply with any Contract related thereto, or the nonconformity of any
     Receivable, the related Contract or any Related Assets with any such
     applicable law, rule or regulation ,

          (c)  the failure to vest and maintain vested in ARC a first priority
     perfected ownership interest in the Receivables, the Related Assets, the
     related Collections and the proceeds of each of the foregoing, free and
     clear of any Adverse Claim (other than an Adverse Claim created in favor of
     ARC pursuant to this Agreement or in favor of the Trustee pursuant to the
     Pooling Agreement), whether existing at the time of the sale of such
     Receivable or at any time thereafter and without regard to whether such
     Adverse Claim was a Permitted Adverse Claim,

          (d)  any failure of the Seller to perform its duties or obligations in
     accordance with the provisions of the Transaction Documents,

          (e)  any products liability claim, personal injury or property damage
     suit, environmental liability claim or any other claim or action by a party
     other than ARC of whatever sort, whether sounding in tort, contract or any
     other legal theory, arising                                               
                                                                         page 32

 
     out of or in connection with the goods or services that are the subject of
     any Transferred Assets with respect thereto or Collections thereof,

          (f)  the failure to file, or any delay in filing, financing statements
     or other similar instruments or documents under the UCC of any applicable
     jurisdiction or other applicable laws with respect to any Transferred
     Assets or Collections, whether at the time of any sale or at any subsequent
     time,

          (g)  any dispute, claim, offset or defense (other than the discharge
     in bankruptcy) of an Obligor to the payment of any Receivable or Related
     Asset, or purported Receivable or Related Asset, including a defense based
     on the Receivable's or the related Contract's not being a legal, valid and
     binding obligation of the Obligor enforceable against it in accordance with
     its terms, and

          (h)  any tax or governmental fee or charge (other than franchise taxes
     and taxes on or measured by the net income of ARC or any of its assignees),
     all interest and penalties thereon or with respect thereto, and all
     reasonable out-of-pocket costs and expenses, including the reasonable fees
     and expenses of counsel in defending against the same, that may arise by
     reason of the purchase or ownership of the Receivables or any Related Asset
     connected with any such Receivable s.

Notwithstanding the foregoing (and with respect to clause (ii) below, without
                                                   -----------               
prejudice to the rights that ARC may have pursuant to the other provisions of
this Agreement or the provisions of any of the other Transaction Documents), in
no event shall any RPA Indemnified Party be indemnified for any RPA Indemnified
Losses (i) resulting from gross negligence or willful misconduct on the part of
the RPA Indemnified Party, (ii) to the extent the same includes losses in
respect of Receivables and reimbursement therefor that would constitute credit
recourse to the Seller for the amount of any Receivable or Related Asset not
paid by the related Obligor, (iii) resulting from the action or omission of the
Servicer (unless the Servicer is an AmeriSource Person), (iv) to the extent the
same are or result from lost profits, (v) to the extent the same are or result
from taxes on or measured by the net income of the RPA Indemnified Party and
(vi) to the extent the same constitute consequential, special or punitive
damages.

     If for any reason the indemnification provided above in this section is
unavailable to a RPA Indemnified Party or is insufficient to hold a RPA
Indemnified Party harmless, then the Seller shall contribute to the maximum
amount payable or paid to the RPA Indemnified Party as a result of the loss,
claim, damage or liability in such proportion as is appropriate to reflect not
only the relative benefits received by the RPA Indemnified Party on the one hand
and the Seller on the other hand, but also the relative fault of the RPA
Indemnified Party (if any) and the Seller and any other relevant equitable
considerations.

- - - ----------------
waiver thereof, nor shall any single or partial exercise of any such power or
right preclude any other or further exercise thereof or the exercise of any
other power or right. No notice to or demand on the Seller in any case shall
entitle it to any notice or demand in similar or other circumstances. No waiver
or approval by ARC or the Trustee under this Agreement shall, except as may

similar or dissimilar waiver or approval thereafter to be granted hereunder.

unpaid principal of this Note shall only become due and payable on the Final
Maturity Date.  Subject to the Subordination Provisions, the principal amount of
and accrued interest on this Note may be prepaid on any Business Day without
premium or penalty; provided, that no prepayment shall be made by ARC to the
extent that such prepayment would result in a default in the payment of any
other amount required to be paid by ARC under any Transaction Document.

     7. Subordination Provisions.  ARC covenants and agrees, and the Holder, by
        ------------------------                                               
its acceptance of this Note, likewise covenants and agrees, that the payment of
all Junior Liabilities is hereby expressly subordinated in right of payment to
the payment and performance of the Senior Interests to the extent and in the
manner set forth in this paragraph:

          (a) In the event of any Bankruptcy Proceeding, the Senior Interests
     shall first be paid and performed in full and in cash before the Holder
     shall be entitled to receive and to retain any payment or distribution in
     respect of the Junior Liabilities. In order to implement the foregoing: (i)
     all payments and distributions of any kind or character in respect of the
     Junior Liabilities to which the Holder would be entitled except for this
     clause (a) shall be made directly to the Certificateholders, and (ii)
     ----------
     if a Bankruptcy Proceeding has been commenced, the Holder shall promptly
     file a claim or claims, in the form required in any Bankruptcy Proceedings,
     for the full outstanding amount the Junior Liabilities, and shall use
     commercially reasonable efforts to cause said claim or claims to be
     approved and all payments and other distributions in respect thereof to be
     made directly to the Certificateholders until the Senior Interests shall
     have been paid and performed in full and in cash. 

          (b) In the event that the Holder receives any payment or other
     distribution of any kind or character from ARC or from any other source
     whatsoever, in payment of the Junior Liabilities, after the commencement of
     any Bankruptcy Proceeding, such payment or other distribution shall be
     received in trust for the Certificateholders and shall be turned over by
     the Holder to the Certificateholders forthwith.

          (c)  Upon the final indefeasible payment in full and in cash of all
     Senior Interests, the Holder shall be subrogated to the rights of the
     Certificateholders to receive payments or distributions from ARC that are
     applicable to the Senior Interests until the Junior Liabilities are paid in
     ull.             

          (d) These Subordination Provisions are intended solely for the purpose
     of defining the relative rights of the Holder, on the one hand, and the
     Certificateholders on the other hand. Nothing contained in these
     Subordination Provisions or elsewhere in this Note is intended to or shall
     impair, as between ARC, its creditors (other than the Certificateholders)
     and the Holder, ARC's obligation, which is unconditional and



                                                                          page 3

 
     absolute, to pay the Junior Liabilities as and when the same shall become
     due and payable in accordance with the terms hereof and of the Agreement or
     to affect the relative rights of the Holder and creditors of ARC (other
     than the Certificateholders).

          (e)  The Holder shall not, until the Senior Interests have been
     finally paid and performed in full and in cash, (i) cancel, waive, forgive,
     transfer or assign, or commence legal proceedings to enforce or collect, or
     subordinate to any obligation of ARC (other than to the Senior Interests),
     howsoever created, arising or evidenced, whether direct or indirect,
     absolute or contingent, or now or hereafter existing, or due or to become
     due, the Junior Liabilities or any rights in respect hereof or (ii) convert
     the Junior Liabilities into an equity interest in ARC, unless, in the case
     of each of clauses (i) and (ii), the Holdershall have received the prior 
                -----------     ----        
     written consent of the Certificateholders in each case.

          (f)  The Holder shall not, without the advance written consent of the
     Certificateholders, commence, or join with any other Person in commencing,
     any Bankruptcy Proceedings with respect to ARC until at least one year and
     one day shall have passed after the Senior Interests shall have been
     finally paid and performed in full and in cash; provided, however, that the
     Holder shall at all times have the right to file any claim in or otherwise
     take any action with respect to any insolvency proceeding instituted
     against ARC by any Person other than the Holder, ARC or any other
     AmeriSource Person (provided that no such action may be taken by the Holder
     until such proceeding has continued undismissed, unstayed and in effect for
     a period of 10 days).
          (g)  If, at any time, any payment (in whole or in part) made with
     respect to any Senior Interest is rescinded or must be restored or returned
     by a Certificateholder (whether in connection with any Bankruptcy
     Proceedings or otherwise), these Subordination Provisions shall continue to
     be effective or shall be reinstated, as the case may be, as though such
     payment had not been made.

          (h)  Each of the Certificateholders may, from time to time, in its
     sole discretion, without notice to the Holder, and without waiving any of
     its rights under these Subordination Provisions, take any or all of the
     following actions: (i) retain or obtain an interest in any property to
     secure any of the Interests, (ii) retain or obtain the primary or secondary
     obligations of any other obligor or obligors with respect to any of the
     Senior Interests, (iii) extend or renew for one or more periods (whether or
     not longer than the original period), alter, increase or exchange any of
     the Senior Interests, or release or compromise any obligation of any nature
     with respect to any of the Senior Interests, (iv) amend, supplement, amend
     and restate, or otherwise modify any Transaction Document to which it is a
     party, and (v) release its security interest in, or surrender, release or
     permit any substitution or exchange for all or any part of any rights or
     property securing any of the Senior Interests, or 


                                                                          page 4

 
     extend or renew for one or more periods (whether or not longer than the
     original period), or release, compromise, alter or exchange any obligations
     of any nature of any obligor with respect to any such rights or property.
    
          (i)  The Holder hereby waives: (i) notice of acceptance of these
     Subordination Provisions by any of the Certificateholders, (ii) notice of
     the existence, creation, non-payment or non-performance of all or any of
     the Senior Interests, and (iii) all diligence in enforcement, collection or
     protection of, or realization upon, the Senior Interests, or any thereof,
     or any security therefor.
     
          (j)  These Subordination Provisions constitute a continuing offer from
     ARC to all Persons who become the holders of, or who continue to hold,
     Senior Interests, and these Subordination Provisions are made for the
     benefit of the Certificateholders, and the Trustee may proceed to enforce
     such provisions on behalf of each of such Persons.

     8. General.  No failure or delay on the part of the Holder in
        -------
exercising any power or right hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such power or right preclude any
other or further exercise thereof or the exercise of any other power or right.
No amendment, modification or waiver of, or consent with respect to, any
provision of this Note shall in any event be effective unless (a) the same shall
be in writing and signed and delivered by ARC and the Seller, and (b) all
consents required for such actions under the Transaction Documents shall have
been received by the appropriate Persons.

     9. Limitation on Interest.  Notwithstanding anything in this Note to the
        ----------------------                                               
contrary, ARC shall never be required to pay unearned interest on any amount
outstanding hereunder, and shall never be required to pay interest on the
principal amount outstanding hereunder, at a rate in excess of the maximum
nonusurious interest rate that may be contracted for, charged or received under
applicable federal or state law (such maximum rate being herein called the
"Highest Lawful Rate").  If the effective rate of interest that would otherwise
be payable under this Note would exceed the Highest Lawful Rate, or the Holder
shall receive any unearned interest or shall receive monies that are deemed to
constitute interest that would increase the effective rate of interest payable
by ARC under this Note to a rate in excess of the Highest Lawful Rate, then (a)
the amount of interest that would otherwise be payable by ARC under this Note
shall be reduced to the amount allowed by applicable law, and (b) any unearned
interest paid by ARC or any interest paid by ARC in excess of the Highest Lawful
Rate shall be refunded to ARC.  Without limitation of the foregoing, all
calculations of the rate of interest contracted for, charged or 


                                                                          page 5

 
received by the Holder under this Note that are made for the purpose of
determining whether such rate exceeds the Highest Lawful Rate shall be made, to
the extent permitted by applicable usury laws (now or hereafter enacted), by
amortizing, prorating and spreading in equal parts during the actual period
during which any amount has been outstanding hereunder all interest at any time
contracted for, charged or received by the Seller in connection herewith. If at
any time and from time to time (i) the amount of interest payable to the Holder
on any date shall be computed at the Highest Lawful Rate pursuant to the
provisions of the foregoing sentence, and (ii) in respect of any subsequent
interest computation period the amount of interest otherwise payable to the
Holder would be less than the amount of interest payable to the Holder computed
at the Highest Lawful Rate, then the amount of interest payable to the Holder in
respect of such subsequent interest computation period shall continue to be
computed at the Highest Lawful Rate until the total amount of interest payable
to the Holder shall equal the total amount of interest that would have been
payable to the Holder if the total amount of interest had been computed without
giving effect to the provisions of the foregoing sentence.

     10  No Negotiation.  This Note is not negotiable.

     12  Security Interest.  The Seller may grant a security interest in or
         -----------------                                                 
otherwise pledge this Note as security, and any Person to whom such security
interest is granted or to whom this Note is pledged shall be bound by, and for
all purposes takes this Note subject to, the restrictions and other provisions
(including the Subordination Provisions) set forth herein.

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


     Reference is made to the Receivables Purchase Agreement of even date
herewith (as the same may be amended, supplemented, amended and restated or
otherwise modified from time to time, the "Agreement") between AMERISOURCE
CORPORATION (the "Seller") and AMERISOURCE RECEIVABLES CORPORATION ("ARC").
Unless otherwise defined herein, capitalized terms used herein have the meanings
provided in Appendix A to the Agreement.

     The Seller hereby sells, transfers, assigns, sets over and conveys unto ARC
and its successors and assigns all right, title and interest of the Seller in,
to and under:

          (a)  each Receivable of the Seller (other than Contributed

          (b)  each Receivable created by the Seller (other than Contributed
     Receivables) that arises during the period from and including the closing
     of the Seller's business on the Initial Cut-Off Date to but excluding the

          (c)  all Related Security with respect to all Receivables (other than

     any Person in payment of any amounts owed (including invoice prices,
     finance charges, interest and all other charges, if any) in respect of any
     Receivable described above (other than a Contributed Receivable) or Related
     Security with respect to any such Receivable, or otherwise applied to repay
     or discharge any such Receivable (including insurance payments that the
     Seller or the Servicer applies in the ordinary course of its business to

                                Title:____________________________



                                                                          page 2

                                                           to Purchase Agreement


                        LITIGATION AND OTHER PROCEEDINGS
                        --------------------------------

A.   Seller is named as a defendant in the following L-Tryptophan lawsuit.
     Seller believes it is entitled to full indemnification by its suppliers and
     the manufacturer of L-Tryptophan with respect to this lawsuit:

     1.   Margaret M. O'Neill, et al. v. Showa Denko, K.K., et al., Court of
          -------------------------------------------------------
          Common Pleas, Cuyahoga County, Ohio, No. 91-218888-CV.

B.   Seller is named as a defendant, along with six other wholesale distributors
     and twenty-four pharmaceutical manufacturers, in 14 civil actions filed in
     the United States District Court for the Southern District of New York. For
     pretrial matters, these cases, along with thirty-four others (to which the
     Company is not a party) have been transferred to the United States District
     Court for the Northern District of Illinois. In general, these lawsuits all
     claim that the manufacturer and wholesaler defendants have combined,
     contracted and conspired to fix the prices charged to plaintiffs and class
     members for prescription brand name pharmaceuticals. Specifically,
     plaintiffs claim that m the defendants use "chargeback agreements" to give
     some institutional pharmacies discounts that are not made available to
     retail drug stores. Seller believes it has meritorious defenses to the
     claims asserted in these lawsuits.

C.   In connection with its examination of the consolidated Federal income tax
     returns of Seller and its subsidiaries for the taxable years ended
     September 30, 1987 through December 29, 1988 and of AmeriSource
     Distribution Corporation and its subsidiaries (including Seller) for the
     taxable years ended September 30, 1989 through September 30, 1991, the
     Internal Revenue Service (the "IRS") has delivered to Seller certain
     Notices of Proposed Adjustment reflecting proposed increases to the taxable
     income of the consolidated groups for those periods.

     The IRS has not yet delivered a Revenue Agent's Report and accompanying"30-
     day letter" upon the conclusion of the examination pursuant to which the
     taxpayers are permitted to file an administrative protest of any proposed
     adjustments with the IRS Appeals Office. Seller expects to contest
     substantially all of the proposed adjustments.

D.   Seller has removed two underground storage tanks (the "USTs") at its
     Charleston, South Carolina facility and is awaiting finalization by the
     South Carolina Department of Health and Environmental Control on its
     closure report. The USTs in South 

 
     Carolina are registered under the state's SUPERB program.
     Seller retained General Engineering Laboratories ("GEL") to study its
     Charleston, South Carolina property and to determine the extent of the
     environmental problem existing at that site.

     GEL completed its Subsurface Soil Investigation and issued a report dated
     October 22, 1993, which identified elevated concentrations of lead in the
     soil at the Charleston, South Carolina facility. Seller then retained RMT,
     Inc. ("RMT") to perform a groundwater investigation at the facility. RMT
     completed its Groundwater Investigation and issued a report dated July
     1994, which found lead in unfiltered groundwater samples taken at the
     facility. Seller submitted RMT's report to the South Carolina Department of
     Health and Environmental Control ("SC DHEC").

     As described in Seller's Form 10-Q for the Fiscal Quarter Ended June 30,
     1994, Seller reserved $4.1 million during the third quarter of fiscal 1994
     to cover future consulting, legal and remediation and ongoing monitoring
     costs for the Charleston, South Carolina facility.

     In September 1994, SC DHEC directed Seller to conduct additional
     groundwater and soil investigations at the facility. In October 1994, RMT
     submitted a proposed workplan to SC DHEC describing the additional
     investigation activities that will be undertaken at the facility.

 
                                                                      SCHEDULE 2
                                                           to Purchase Agreement
