                     SECOND AMENDMENT TO CREDIT AGREEMENT

     This SECOND AMENDMENT TO CREDIT AGREEMENT (this "SECOND AMENDMENT") is
entered into as of March 5, 2001, by and between GEERLINGS & WADE, INC., a
Massachusetts corporation (the "BORROWER") and CITIZENS BANK OF MASSACHUSETTS, a
Massachusetts bank (the "LENDER").

     All capitalized terms not defined herein but defined in that certain Credit
Agreement, dated as of April 13, 2000, by and between the Borrower and the
Lender, as amended by a certain First Amendment to Credit Agreement, dated as of
December 4, 2000, by and between the Borrower and the Lender (said Credit
Agreement, as so amended, is hereinafter referred to collectively as the "CREDIT
AGREEMENT"), shall have the meanings given to such terms in the Credit
Agreement.

                            Preliminary Statements:
                            ----------------------

     A. Pursuant to the Credit Agreement and the other Financing Documents, the
Lender has made or agreed to make certain Loans to the Borrower; and

     B.  The Borrower has requested that the Lender grant certain financial
accommodations for the benefit of the Borrower with respect to the Loans, all as
more particularly described herein; and

     C.  The Lender is unwilling to comply with the foregoing request of
the Borrower, unless and until the Borrower has entered into, and agreed to, all
of the terms and conditions of, this Second Amendment;

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

     1. Waiver of Certain Events of Default. At the request of the Borrower, the
Lender hereby waives, for the Borrower's fiscal quarter ended December 31, 2000
only, any Default or Event of Default which has occurred or may have occurred as
a result of the failure of the Borrower to comply with any of the financial
covenants contained in subsection 6.1 of the Credit Agreement. The foregoing
waiver shall operate solely with respect to the matters and period of time
described herein, and shall not impair any right or power accruing to the Lender
upon the occurrence or continuance of any other Default or Event of Default
under the Credit Agreement and the other Financing Documents, nor shall the
waiver contained herein be construed as a waiver of any such other Default or
Event of Default or as an acquiescence thereto.
<PAGE>

     2. Amendments to Credit Agreement. The definition of the term "Maximum
Amount" contained in Appendix A of the Credit Agreement is hereby amended,
replaced and superseded in its entirety with the following definition:

          "'MAXIMUM AMOUNT': $1,900,000.00, which amount shall automatically and
     without notice be reduced by $50,000.00 on the 1st and the 15th of each
     calendar month, commencing as of March 15, 2001 and continuing thereafter
     until such time as the Lender receives, in accordance with the provisions
     of subsection 5.2(b), a Compliance Certificate which indicates that (a) the
     Borrower is in compliance with all of the financial covenants contained in
     subsection 6.1 of this Agreement, and (b) no Event of Default has occurred
     and is continuing hereunder, and there does not now exist any circumstance
     or set of facts, which with the passage of time or the giving of notice or
     both would constitute or result in any such Event of Default."

     3.  Representations and Warranties.  The Borrower hereby acknowledges and
confirms that all of its representations and warranties contained in the Credit
Agreement and in all of the other Financing Documents are and remain true,
correct and complete as of the date hereof as if made as of the date hereof,
except as the same may expressly relate to an earlier date.

     4. No Events of Default. The Borrower hereby represents and warrants to the
Lender that except as otherwise provided in Section 1 of this Second Amendment,
no Event of Default has occurred and is now continuing under the Credit
Agreement or under any of the other Financing Documents, and there does not now
exist any circumstance or set of facts, which with the passage of time or the
giving of notice or both would constitute or result in an Event of Default under
the Credit Agreement or under any of the other Financing Documents.

     5. Ratification of Financing Documents. Subject to the amendments expressly
set forth in Section 2 of this Second Amendment, the Borrower hereby ratifies
and reaffirms all of the terms and provisions of the Financing Documents and
hereby expressly acknowledges and confirms that the terms and provisions of each
thereof, as amended hereby, shall and do remain in full force and effect. Any
