                      FIRST AMENDMENT TO SERVICES AGREEMENT
                BETWEEN B-III CAPITAL, LLC AND PET QUARTERS, INC.
                           AND STOCK OPTION AGREEMENT
               BETWEEN ROBERT M. BROWN, III AND PET QUARTERS, INC.
               ---------------------------------------------------

THIS FIRST AMENDMENT ("Amendment") to the Services Agreement between B-III
Capital, LLC ("B-III") and Pet Quarters, Inc. ("Pet Quarters") dated as of
October 25, 1999 ("Services Agreement") and Stock Option Agreement between
Robert M. Brown, III ("Brown") and Pet Quarters dated as of November 8, 1999
("Stock Option Agreement"), is entered into to be effective as of the last date
written below.

                                    RECITALS

WHEREAS, B-III and Pet Quarters entered into the Agreement and anticipated
paying B-III "success fees" equal to three percent (3%) of cash paid for any
shares of common stock of Pet Quarters acquired by an investor procured for Pet
Quarters by B-III; and

WHEREAS, B-III and Pet Quarters anticipate closing several private and public
placements with or through Ladenburg Thalmann & Co., Inc. ("Ladenburg") or Keane
Securities, Inc. ("Keane"), investors procured for Pet Quarters by B-III; and

WHEREAS, B-III and Pet Quarters agree that B-III's success fee for private or
public placements with or through Ladenburg or Keane should be one percent (1%)
instead of three percent (3%); and

WHEREAS, Brown and Pet Quarters agree that in certain events the vesting
schedule for a portion of Brown's options to purchase common stock of Pet
Quarters under the Stock Option Agreement should be accelerated; and

NOW, THEREFORE, in consideration of the respective promises contained in the
Agreement, B-III, Brown and Pet Quarters agree as follows:

1.       Paragraph 2 - "Success Fees" of the Services Agreement is amended to
         read,

         In connection with the private placement of any Pet Quarters shares
         negotiated by B-III to an investor procured for Pet Quarters by B-III,
         other than Ladenburg Thalmann & Co, Inc. ("Ladenburg") or Keane
         Securities, Inc. ("Keane"), Pet Quarters agrees to pay B-III a success
         fee in cash in an amount of three percent (3%) of the net cash
         consideration received by Pet Quarters for such shares, less any
         retainer fees paid to B-III and not previously so credited, payable on
         B-III's instructions at closing of the private placement. In connection
         with the private placements of any Pet Quarters shares negotiated by
         B-III to Ladenburg or Keane, Pet Quarters agrees to pay B-III a success
         fee in cash in the amount of one percent



   2

         (1%) of the net cash consideration actually received by Pet Quarters,
         less any retainer fees to B-III paid and not previously so credited,
         payable within twenty (20) days after the closing of any transaction
         with or through Ladenburg or Keane. The success fees referenced above,
         whether referring to a 3% or a 1% fee, also applies to the net proceeds
         received by Pet Quarters from any debt placed by B-III on Pet Quarters'
         behalf, less any retainer fees paid to B-III and not previously
         credited.

2.       Paragraph 3 of the Stock Option Agreement is amended to read,

         Acceleration of Vesting. Upon the occurrence of a "change in control"
         of the Company, or (ii) a successful public offering of registered
         shares of the Company, or (iii) the termination of the Services
         Agreement by the Company without cause, the Option granted hereby shall
         thereupon be fully vested and may thereafter be exercised for 100% of
         the shares covered thereby, notwithstanding the vesting and exercise
         schedule set forth in Section 2 above. A "change in control" of the
         Company shall mean the transfer, whether in a single transaction or a
         series of transactions, occurring within a two (2) month period, of
         more than 50% of the voting equity securities or voting control of the
         Company to any person or group of persons acting in concert, if such
         person (or all persons in such group) were not, as of the date of this
         Agreement, owners of at least one share of the Company's common stock;
         provided, however, that a transfer of the Company's common stock by
         gift, bequest or inheritance shall not be deemed a transfer for
         purposes of determining if a change in control has occurred, and
         provided further that any person who has received shares of the
         Company's common stock by gift, bequest or inheritance, directly or
         indirectly from a person who owned at least one share of the Company's
         common stock as of the date of this Agreement, shall be deemed a person
         who owned at least one share of the Company's common stock as of the
         date of this Agreement. Upon the closing of a private placement of
         shares of Pet Quarters negotiated by B-III to an investor procured for
         Pet Quarters by B-III, as outlined in and contemplated by paragraph 2 -
         Success Fees of that certain Services Agreement dated as of October 25,
         1999, by and between B-III and Pet Quarters, as amended, one-half (1/2)
         of the unvested shares under this Agreement shall vest and become
         immediately exercisable by Brown. The shares designated for accelerated
         vesting under this provision shall be selected in inverse order of
         scheduled vesting as set forth in paragraph 2 hereof, commencing with
         those shares scheduled to vest on November 8, 2001.

3.       The remaining terms of the Services Agreement and the Stock Option
Agreement shall remain unchanged unless such terms would be in conflict with the
amendments set forth herein, and then the Services Agreement and Stock Option
Agreement should be read to incorporated the changes contemplated hereby and in
accordance herewith.
