approved bid, and (ii) within five business days after such approval, enter into
a contract of sale including, but not limited to, the approved purchase price,
the name of the successful Buyers and the form of the Buyers price;

               12.5 In the event a successful bidder at the Sale Hearing fails
to close, through no fault of the Sellers, Sellers shall be permitted to enter
into a similar agreement with the next highest bidder, including Buyers (as long
as such bidder complies with all terms and conditions of the sale) without the
necessity of a further order of the Bankruptcy Court.

any or all of the Acquired Assets to an entity other than Buyers for any reason
other than Buyers' default hereunder or in the event the Bankruptcy Court fails

                                   EXHIBIT A

                                PROMISSORY NOTE

PRINCIPAL AMOUNT: $14,000,000.00                  ISSUE DATE: SEPTEMBER 22, 2000
MATURITY DATE:    ONE YEAR AND ONE DAY            LOAN NO.:

For Value received, Electronic Medical Distribution, Inc., a Delaware
corporation with an address at 5655 Peachtree Parkway, Norcross, GA., 30092,
(the "Maker") promises to pay Corey-Channing Trust, (together with all
subsequent holders in due course) at 611 South Palm Canyon Drive, Suite 7-158,
Palm Springs, CA 92264 (the "Holder"), the principal sum of $14,000,000.00
(fourteen million US Dollars and No/cents) lawful money of the United States of
America, with Interest from the date hereof at the rate of ___% (________
percent) simple interest per annum on the terms hereinafter set forth.

This Promissory Note (the "Note") is issued under the terms of an Irrevocable
Collateral Assignment of Stock & Loan Agreement (the "Agreement"), and all
other exhibits to same are made part of the note, dated as of September 18,
2000 between Maker and Holder.

1.   PAYMENT TERMS

     Principal. If the Loan Period, i.e., the time between the date of this Note
     and the Maturity Date, is one year, and one month then no Principal Amount
     must be repaid until the Maturity Date. However, if the Loan Period is more
     than one year and one day, then 20% of the Principal Amount must be repaid
     on each anniversary of this Note prior to the Maturity Date. All remaining
     unpaid Principal Amount is due on the Maturity Date.

     Interest. Interest is due each quarter in arrears. Interest is calculated
     on a "simple" basis, i.e. one-fourth of the Interest Rate is due at the end
     of each quarter.

     All amounts are stated and payable in US Dollars.

2.   NO DEDUCTION OR SET-OFF

     The principal and interest shall be payable without set-off or deduction,
     unless specifically added by addendum to the Note, at the address of the
     Holder set forth in the heading hereof, or at such other place as Holder
     may designate in writing.

3.   PREPAYMENT; PREPAYMENT LIMITATION

     The Maker may prepay any and all principal at any time after the first
     ninety (90) days. If only a portion of the Principal Amount is repaid, no
     interest needs to be concurrently repaid (unless due). However, if the
     entire principal amount is repaid, or that portion of principal which
     extinguishes the balance of the principal, then all accrued interest must
     also be paid to effect cancellation of the entire obligation.

<PAGE>   7

4.   DEFAULT INTEREST

     Any principal or Interest not paid when due, in addition to being an Event
     of Default, shall bear interest thereafter at the aforesaid rate plus 15%
     (fifteen percent) per annum simple Interest.

5.   EVENTS OF DEFAULT

     The occurrence of any one or more of the following events shall constitute
     an "Event of Default" hereunder:

         (a)  Maker shall have made an assignment for the benefit of creditors
              of composition with creditors: or is unable or admits in writing
              its inability to pay its debts as they mature; or any proceeding
              relating to Maker under any bankruptcy, bankruptcy reorganization,
              arrangement, readjustment of debt, receivership, dissolution
              liquidation law or statute of any jurisdiction, whether now or
              hereafter in effect is commenced by or against Maker.

         (b)  Any representation or warranty make by Maker in the Agreement
              shall be false or misleading in material respect; or

         (c)  Maker shall breach or fail to take any actions required,
              obligated, or necessary to maintain or fulfill the Agreement; or

         (d)  Maker shall fail to make a timely interest payment or principal
              repayment. "Timely" shall mean with ten (10) business days of when
              it was due.

6.   ACCELERATION; REMEDIES

     Should any Event of Default occur hereunder, then Holder with written
     notice given Maker, Maker then has (10) ten business days to cure said
     default, at its option, unless expressly required elsewhere, may declare
     immediately due and payable the entire unpaid balance of principal and all
     other sums due by Maker hereunder with interest accrued thereon at the
     Default Rate as set forth herein; and, payment thereof may be enforced by
     liquidating the collateral. "Liquidation" shall mean the Holder may dispose
     of the Stock by any means to satisfy the Maker's obligation. "Dispose of
     the Stock by any means" includes: sale, assignment, hypothecation,
     transfer, or other any method Holder employs, provided however, that Maker
     should be entitled to any monies derived through the remedies hereunder
     only in the amount of unpaid principal and interest then due by default. If
     Holder retains counsel to enforce this Note to ensure title and liquidation
     of the collateral, such cost shall be at Makers expense. "Monies" shall be
     interpreted strictly as cash receipts realized by the Holder. The
     definition shall not include non-monetary benefits, credit lines, or other
     benefits which the Holder may enjoy from deployment and any remedies given
     against the collateral.

     Any and all collateral held under the Irrevocable Collateral Assignment of
     Stock & Loan Agreement, with all other exhibits to same made part of this
     note, may be used against the Collateral in furtherance, sold, assigned,
     hypothecated, or otherwise disposed of to recover amounts enumerated above.

EXHIBIT A                     PROMISSORY NOTE                      PAGE 2 OF 4

<PAGE>   8
     The Holder accepts no liability as to price, purchaser, or other
     considerations in the disposition of such collateral and the Maker waives
     any right through arbitration or legal remedy to seek to make Holder
     accountable for such.

7.   NON-RECOURSE OF NOTE

     The Holder acknowledges the sufficiency of the collateral, i.e., the Stock,
     as adequate and sufficient for the principal amount advanced and any
     deficiencies that may arise to the Maker and that the Holder is precluded
     and estopped from making any and all claims against the Maker for other
     assets, guarantees, or actions against any individual, Trust, corporation
     or entity for recovery of any amount owned to the Holder, except in the
     fraudulent inducement, incomplete conveyance of the Stock such that the
     Holder, after an Event of Default, is unable to liquidate such Stock; or,
     material misrepresentations and invalid warranties of the Maker which
     caused the Holder to enter into the transition.

8.   CONSENT TO WAIVERS

     Maker and all endorsers, sureties, and guarantors consent to any and all
     extensions of time, renewals, waivers or modifications that may be granted
     by Holder with respect to the payment of other provisions of this Note, and
     to release of collateral or any part thereof, with or without substitution.

9.   PARTIAL INVALIDITY

     If any provision of this Note is held to be invalid or unenforceable by a
     court of competent jurisdiction, the other provisions of this Note shall
     remain in full force and effect and shall be liberally construed in favor
     of Holder in order to effect the provisions of this Note. In addition, in
     no event shall the rate of interest exceed the maximum rate of interest
     permitted to be charged by applicable law (including the choice of law
     rules) and any interest paid in excess of the permitted rate shall be
     refunded to Maker. Such refund shall be made by application of the
     excessive amount of interest paid against any sums outstanding and shall be
     applied in such order as Holder may determine. If the excessive amount of
     interest paid exceeds the sums outstanding, Holder shall refund the portion
     exceeding the said sums outstanding in cash. Maker agrees, however, that in
     determining whether or not any interest payable under this Note exceeds the
     highest rate permitted by law, any non-principal payment, including without
     limitation prepayment fees and late charges, shall be deemed to the extent
     permitted by law to be an expense, fee, premium or penalty rather than
     interest.

10.  WAIVERS BY HOLDER

     Holder shall not be deemed, by any act of omission or commission to have
     waived any of its rights or remedies hereunder unless such waiver is in
     writing and signed by Holder, and then only to the extent specifically set
     forth in the writing. A waiver on one event shall not be construed as
     continuing or as a bar to or waiver of any right or remedy to a subsequent
     event.

11.  GOVERNING LAW

     This instrument shall be governed by and construed according to the laws of
     the state of California.
