                         LEASE MODIFICATION AGREEMENT
                         ----------------------------

     This Lease Addendum and Modification Agreement (hereinafter referred to
as "the Modified Lease") is made this 23rd day of June, 1998, by and between
Blue II LLC (hereinafter referred to as "Landlord") and Frederick Brewing
Company, a Maryland corporation, (hereinafter referred to as "Tenant").

     WHEREAS, Landlord and Tenant entered into a Lease Agreement dated July 17,
1996 (hereinafter referred to as "Lease") for the rental of the Blue Ridge
Brewery Building located at  4607 Wedgewood Boulevard, Frederick, MD 21703
(formerly Lot 13 at Wedgewood Business Park); and

     WHEREAS, the rent set forth in the Lease needs to be modified to reflect
an increase in the interest charged by the Landlord's lender and for the
possibility of exercising the Tenant's option to purchase; and

     WHEREAS, the option to purchase set forth in the Lease needs to be
modified to allow for the possible assignment of partial rent proceeds towards
the purchase;

     WHEREAS, Tenant acknowledges that it desires, requests and freely agrees
to this Lease Modification after consultation with its board of directors and
counsel;

     NOW, THEREFORE, WITNESSETH:

     The Undersigned, being all of the parties to said Lease, do hereby agree,
for good and valuable consideration, the receipt of which is hereby
acknowledged, to the following modifications:

     I.   Sections 4A, 4B and 4C of the Lease shall be deleted in their entirety
and replaced with the following:
<PAGE>

     4A.  (i)  $17,857.14 (Landlord's equal monthly principal curtailments of
$3,000,000.00 loan over a 14-year period), or (ii) such other principal amounts
as may be applicable, from time to time, if Landlord's loan is modified,
adjusted or refinanced or defaulted and Tenant consents to such modification,
adjustment or refinancing and such default, if any, is not the result of any
act, omission or condition of Tenant;

     4B.  (i)  Interest on the unpaid principal balance of such loan (on a
declining basis) which shall be equal to the prime rate announced from time to
time by First Union Bank, N.A., plus one and one-half percent (1.5%) annually
beginning on July 1, 1998, which can be adjusted up or down by First Union Bank,
N.A. (the successor to Signet Bank) or any assignee of said lender including,
but not limited to, FCNB Bank (the potential assignee from First Union, N.A.),
or (ii) such other rate and terms as may be applied from time to time if such
loan is modified, adjusted, refinanced or defaulted, and Tenant consents to such
modification, adjustment, refinancing and such default, if any, is not the
result of any act, omission or condition of Tenant; provided that, if Tenant
                                                    -------------
does not consent to such modification, adjustment or refinancing, Landlord may
nevertheless modify, adjust or refinance so long as Tenant's obligations to
Landlord under the lease are not increased;

     4C.  Eleven Thousand Two Hundred Fifty Dollars ($11,250.00) per month of
which Eight Thousand Two Hundred Fifty Dollars ($8,250.00) per month shall be
credited to the Tenant for the next twelve (12) months beginning June 1, 1998
towards the option to purchase amount as modified below in the event the Tenant
purchases the property or the membership interest of the Seller.

     II.  Section 39 (Purchase Option) shall be modified and amended as follows:

                                       2
<PAGE>

     A.     Beginning on the sixty (6th) line after "...following the" delete
"sixth (6th)" and insert "second (2nd)".

     B.     Delete "sixth (6th)" on the ninth (9th) line and insert "second
(2nd)".

     C.     Beginning on the thirteenth (13th) line after "The executed Contract
of Sale may...", delete the word "not".

     D.     Delete the eighteenth (18th) line starting with "If Tenant" through
the end of the sentence on the twenty-second (22nd) line.

     III.   Exhibit C to the Contract shall be modified and amended as follows:
            A new paragraph shall be added;

     Section 12.

     Notwithstanding anything in the Contract to the contrary, Purchaser shall
have the right to purchase the Seller's membership interest in their LLC anytime
after the first anniversary of the Modified Lease (June 30, 1999) for the sum
of Three Hundred Fifty Thousand Dollars ($350,000.00) plus assuming the existing
financing and related guarantees.  In the event the Tenant chooses to exercise
this option, then in that event, the Landlord shall credit the sum of Eight
Thousand Two Hundred Fifty Dollars ($8,250.00) per month of the rent paid times
the number of months from July 1, 1998 through their settlement date, which
must occur on or before June 30, 1999 (i.e., Purchase of membership interest
June 30, 1999; $8,250.00 x 12 months = $100,000.00; $350,000.00 purchase price
of membership interest minus $100,000.00 rent credit = $250,000.00 remaining
payment).

     IV.    The Lease Modification will remain in full force and effect upon
the refinancing of Landlord's mortgage loan on terms substantially similar to
those set out in the FCNB term

                                      3
<PAGE>

sheet dated April 28, 1998, including the proposed reduction in the interest
rate to 1.25% above the Wall Street Journal's published Prime Rate. Landlord
will agree to execute such documents as may be required to effect such a
refinancing without further modifications of the lease or other concessions by
either Tenant and its individual officers or directors, or Landlord and its
guarantors.

     V.  The remaining provisions of the Lease shall remain in full force and
effect.
