                                PLEDGE AGREEMENT
                                ----------------

            Pledge Agreement (`Agreement") made and effective as of this 23rd
day of February, 2001, by and between RXBAZAAR.COM, INC., a Delaware corporation
with a principal place of business at 11895 Kemper Springs Drive, Cincinnati,
Ohio 45240 ("Pledgor") and THE CIT GROUP/BUSINESS CREDIT, INC., a New York
corporation having its principal place of business at 1211 Avenue of the
Americas, New York, New York 10036 (the "Pledgee" ).

            WHEREAS, the Pledgee has extended certain credit facilities (the
"Loan") to Superior Pharmaceutical Company, an Ohio corporation with a place of
business at 11895 Kemper Springs Drive, Cincinnati, OH 42540 ("Superior"), as
evidenced by, inter alia, a Financing and Security Agreement of even date
herewith (the "Financing Agreement") and a Revolving Loan Promissory Note of
even date herewith (the "Note"); and

            WHEREAS, the Pledgor is the owner of 100% of the issued and
outstanding capital stock of Superior, as more particularly set forth on Exhibit
A annexed hereto and made a part hereof (such shares of capital stock are
hereinafter referred to collectively as the "Shares"); and

            WHEREAS, as a condition to granting the Loan and as security
therefor, the Pledgee has required that the Pledgor pledge all of the Shares to
the Pledgee in accordance with the terms of this Agreement.

            NOW, THEREFORE, in consideration of the mutual promises and
covenants contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Pledgor and the
Pledgee agree as follows:

            1. Capitalized Terms. Capitalized terms that are used but not
otherwise defined herein shall have the meanings ascribed to them in the
Financing Agreement.

            2. Pledge of Shares. The Pledgor does hereby grant a security
interest in and assign the Shares in pledge to the Pledgee in accordance with
the terms of this Agreement. The certificates representing the Shares, along
with stock powers executed in blank, have been delivered to the Pledgee
contemporaneously herewith, receipt of which the Pledgee acknowledges.

            3. Pledge as Security. The Shares pledged by the Pledgor to the
Pledgee pursuant hereto shall be held by the Pledgee in trust hereunder as
security for the Obligations.

            4. Distributions. If a stock dividend shall be paid on the Shares,
the shares to be issued in connection therewith (the "Stock Dividend Shares")
shall be deemed to be part of the Shares and the Pledgor shall deliver, or cause
to be delivered to the Pledgee, the certificate(s) representing the Stock
Dividend Shares and the Pledgor shall execute and deliver to the Pledgee such
other and further agreements, instruments and writings as the Pledgee, in its
reasonable discretion, shall deem necessary or advisable to grant to the Pledgee
a security interest in the Stock Dividend Shares, including without limitation,
a pledge agreement, stock powers executed in blank and an irrevocable proxy
coupled with an interest.

            5. Voting of Shares. So long as no Event of Default has occurred and
is continuing, the Pledgor shall be entitled to vote the Shares. Upon the
occurrence of an Event of Default and while any such Event of Default is
continuing, the Pledgee shall be entitled to vote the Shares, and for such
purposes, the Pledgor does hereby give to the Pledgee its irrevocable proxy,
coupled with an interest, to vote the Shares. If the Pledgee shall be entitled
to vote the Shares, then the Pledgee may vote the Shares on any matter or
proposal on which such Shares are entitled to vote in any fashion in which the
Pledgee, in its discretion, may determine.

            6. Disposition of Shares by Pledgor. The Pledgor shall have no right
to dispose of the Shares, or any of them, before the Shares are released from
this Agreement in accordance with Section 8 hereof.

            7. Default.

                (a) "Event of Default" shall mean (i) the occurrence of an Event
of Default, as defined in the Financing Agreement or (ii) the Pledgor's breach
of any warranty, representation, covenant or agreement contained herein.

                (b) Upon the occurrence of an Event of Default:

                    (i)   The Pledgee shall have the rights of a secured party
                          under the Uniform Commercial Code, as adopted in the
                          State of New York, with respect to the Shares.

                    (ii)  The Pledgee may sell, resell, assign and deliver,
                          grant options for or otherwise dispose of the Shares,
                          at public or private sale, for cash or credit and on
                          such commercially reasonable terms as the Pledgee, in
                          its discretion, may deem desirable, without prior
                          demand for performance upon the Pledgor but with seven
                          (7) days' prior written notice thereof given to the
                          Pledgor.

                (c) The proceeds realized upon any disposition of the Shares by
the Pledgee pursuant to this Section 7 shall be applied as follows:

                    (i)   First, to the reasonable costs and expenses, including
                          attorneys' reasonable fees, incurred by the Pledgee in
                          the enforcement of its rights and remedies under, and
                          the performance of, this Agreement and the
                          Obligations;

                    (ii)  Second, to the payment of the Obligations; and

                    (iii) Third, to the payment of any surplus then remaining to
                          the Pledgor or other person(s) entitled thereto.

            8. Release of Shares from Pledge. Upon the full and complete
payment, performance and satisfaction of the Obligations, the Shares shall be
released from this Agreement and shall be delivered by the Pledgee to the
Pledgor unless Pledgee is required to deliver same to any junior or subordinated
pledgee.

shall:

                (a) Notify the Pledgee of any claim, lien, security interest or
other encumbrance made against the Shares and shall warrant and defend the
Shares against any such claim, lien, security interest or other encumbrance
senior and adverse to the Pledgee; and

                (b) At any time and from time to time execute and deliver to the
Pledgee such further instruments, and take such further action as the Pledgee

when appropriate, to terminate the interest of the Pledgee in the Shares
hereunder.

            10. Representations and Warranties of Pledgor. The Pledgor
represents and warrants to the Pledgee that:

                (a) The Pledgor possesses all requisite power to enter into this
Agreement, to pledge to the Pledgee the Shares and to perform its obligations
hereunder;

                (b) This Agreement constitutes the valid and binding obligation
of the Pledgor, enforceable in accordance with its terms, and the execution,
delivery and performance of this Agreement does not and will not (i) to the
Pledgor's knowledge violate any provision of law or Pledgor or Superior's
articles of incorporation or by-laws, or (ii) conflict with, or result in
the-breach of any of the terms, conditions or provisions of, or constitute a
default under, any material agreement, instrument, indenture, mortgage, lease or
other contract to which the Pledgor is a party or by which the Pledgor is bound;

                (c) the Shares were duly authorized and validly issued to the
Pledgor, are fully paid and nonassessable, and the Pledgor owns the Shares free
and clear of the interests of any party whatsoever; and

                (d) no permit, consent, approval or authorization of, or
declaration to or filing with, any governmental or regulatory authority is
required of or by the Pledgor in connection with the execution and delivery of,
and consummation of the transactions contemplated by, this Agreement, other than
Uniform Commercial Code filings with respect to this Pledge Agreement.

            11. Assignment. The rights and obligations of the Pledgor hereunder
are personal to the Pledgor, and such rights may not be assigned by the Pledgor,
and such obligations may not be delegated by the Pledgor, without the prior
written approval of the Pledgee.

            12. Enforceability; Effect. This Agreement shall be binding upon,
and shall inure to the benefit of, and be enforceable by and against, the
parties hereto and their respective heirs, representatives, successors and
permitted assigns.

            13. Severability. The provisions of this Agreement are severable,
and if any one or more provisions are determined to be illegal or otherwise
unenforceable, in whole or in part, the remaining provisions, and any partially
unenforceable provisions to the extent enforceable in any jurisdiction, shall
nevertheless be binding and enforceable.

                        LIQUIDATION ASSISTANCE AGREEMENT

Liquidation Assistance Agreement ("Agreement"), dated February 23, 2001 among
__________________ ("Principal"), an individual with an address at
____________________________, Superior Pharmaceutical Company, a Delaware
corporation with an address at 1385 Kemper. Meadow Drive, Cincinnati, Ohio 45240
(the "Company") and RxBazaar.com, Inc., a Delaware corporation with an address
at 11895 Kemper Springs Drive, Cincinnati, Ohio 45240 ("RxBazaar"; RxBazaar and
the Company are sometimes referred to herein collectively as the "Debtor") and
The CIT Group/Business Credit, Inc., a New York Corporation, with an address at
1211 Avenue of the Americas, New York, New York 10036 ("CIT").

                                   WITNESSETH
                                   ----------

WHEREAS, CIT, the Company and RxBazaar have entered into or are about to enter
into a Financing and Security Agreement dated on or about the date hereof (the
"Financing Agreement");

WHEREAS, pursuant to the Financing Agreement, the Debtor has granted to CIT a
continuing general lien and security interest in all of its Accounts, Inventory,
General Intangibles, Documents of Title, Other Collateral, Equipment and Real
Estate (as defined in the Financing Agreement, collectively, herein the
"Collateral") to secure the Obligations (as defined in the Financing Agreement);

WHEREAS, upon the occurrence and during the continuance of an Event of Default
(as defined in the Financing Agreement), the Debtor, at the request of CIT,
agrees to assemble and collect the Debtor of the Company and to make it
available to CIT at the premises of the Debtor for the purpose of CIT's taking
possession of, removing or putting the Collateral in saleable form; and

WHEREAS, to further secure the Company's Obligations to CIT, Principal, in his
capacity as an officer of the Debtor agrees to assist the Company in assembling,
collecting and delivering the Collateral to the premises of the Debtor in
accordance with the terms of this Agreement.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency
of that are acknowledged, Principal, the Debtor and CIT agree as follows:

1. In the event CIT declares an Event of Default under the Financing Agreement
and as a result thereof (a) thereafter commences to liquidate and realize upon
the Collateral or (b) CIT is collecting the Accounts (in either case, a
"Liquidation"), Principal agrees to use his commercially reasonable efforts to
assist the Debtor and CIT in assembling, collecting and disposing of the
Collateral and the Accounts for a period not to exceed the lesser of (i) six (6)
months from the declaration of the Event of Default or (ii) the date upon which
CIT has liquidated the Collateral (as determined by CIT in its reasonable
discretion), so long as (x) Principal is continuing to be paid his standard
compensation and receive his standard benefits from the Debtor (provided that
such compensation and benefits are commercially reasonable and in accordance
with the Debtor's past practices) and (y) the Debtor and/or CIT (and, not the
Principal) pay any and all expenses necessary to accomplish the foregoing.
Principal and the Debtor shall use their commercially reasonable
<PAGE>

efforts to obtain sales of the Collateral at commercially reasonable prices and
terms and to collect Accounts at their full face value. CIT shall have the right
to terminate the activities of Principal or the Debtor described above at any
time, for any reason, with or without cause.

2. Upon the commencement of a Liquidation, all monies (other than those
appropriate to operate the Debtor, as mutually determined by the Debtor and CIT)
received by either Principal or the Debtor shall be immediately applied to the
Obligations, except as otherwise required by law; it being understood, however,
that Principal does not control the activities of the Debtor.

3. With respect to the disposition of the Collateral or the collection of
Accounts, all efforts shall be undertaken in the name of Principal and the
Debtor and not in the name of CIT. Principal and the Debtor agree that they
shall not hold themselves out as, or represent that they are, agents of CIT.
Neither Principal nor the Debtor shall have the authority to bind CIT except as
such specific authority as CIT may grant in writing from time to time.

4. The Debtor agrees that it shall be solely responsible for all reasonable
legal and appraisal costs and expenses, including all professional fees, court
costs, and other costs incurred in connection with the disposition of the
Collateral or the collection of the Accounts. From time to time, as reasonably
requested by CIT, Principal and the Debtor shall submit to CIT statements
showing the amount of payments received with respect to the collection and
disposal efforts outlined in this Agreement.

5. The Debtor acknowledges that CIT, in making and extending financial
accommodations to the Company, relied upon the terms of this Agreement. The
Debtor acknowledges that CIT has a contractual right to rely, and is relying,
upon Principal to cooperate with the Debtor in performing his obligations under
this Agreement. The Debtor represents and acknowledges to CIT that in the event
Principal breaches the terms of this Agreement, CIT will be damaged. The Debtor
hereby assigns to CIT all claims, causes of action, and rights to pursue
remedies that the Debtor may have against Principal by reason of Principal's
breach of this Agreement.

6. The Debtor hereby indemnifies and holds harmless CIT from any and all costs,
expenses, damages and liabilities that have been or in the future might be
suffered or incurred as a result of or arising out of any negligent, wrongful or
improper action or omission in connection with the collection of amounts owed
under the Financing Agreement.

7. The Principal hereby indemnifies and holds harmless CIT from any and all
costs, expenses, damages and liabilities that might be suffered or incurred as a
result of or arising out of Principal's breach of his obligations under this
Agreement so long as CIT has provided Principal with written notice of such
breach within ten (10) days of such breach and Principal is given ten (10) days
from his receipt of such notice to cure such breach.

8. Principal and the Debtor agree (a) that, except as to CIT's successors and
assigns, this Agreement is not intended for and shall not be construed for the
benefit of any party not a signatory hereto; (b) that this Agreement constitutes
the entire agreement among the parties with respect to the subject matter hereof
and no modification or waiver shall be effective unless in writing and signed by
the party to be charged; (c) the inapplicability or unenforceability of any
provision of this Agreement shall not limit or

                                      -2-
<PAGE>

impair the operation or validity of any provision of the Agreement; and (d) this
Agreement shall be binding upon, and inure to the benefit of the respective
successors and assigns of the parties hereto.

9. In the event of any inconsistency between the terms of this Agreement and the
terms of the Financing Agreement, the terms of the Financing Agreement shall
govern.

10. This Agreement shall be governed by, and interpreted in accordance with, the
laws of the State of New York.

11. This Agreement may be executed in any number of counterparts which together
shall constitute one and the same instrument.

IN WITNESS WHEROF, each of the parties hereto has caused this Agreement to be
executed and delivered by its duly authorized officer as of the date first
written above.
