                                   ADDENDUM TO
                              PRODUCTION AGREEMENT
                                     BETWEEN
                             MILLER BREWING COMPANY
                                       AND
                             BOSTON BEER CORPORATION

     THIS ADDENDUM, made as of the 31st day of August, 2006, supplements and
modifies the Amended and Restated Production Agreement (the "Agreement") dated
as of November 1, 1998 between Miller Brewing Company ("Miller"),
successor-in-interest to The Stroh Brewery Company, and Boston Beer Corporation
("Boston Beer"), successor-in-interest to Boston Beer Company Limited
Partnership, as amended and modified by letter agreement dated September 9,
2000.

     WHEREAS, Boston Beer has been brewing and packaging Beer Products under the
Agreement as an alternating proprietor at the breweries owned and operated by
Miller;

     WHEREAS, the requirements for operating as an alternating proprietor have
been modified pursuant to Industry Circular 2005-2 promulgated by the Alcohol
and Tobacco Trade and Tax Bureau of the U.S. Department of the Treasury (the
"TTB"), which, in turn, have required certain clarifications and/or changes to
be made in the administration of the relationship between the Parties in order
for Boston Beer to continue to operate at Miller's breweries as an alternating
proprietor; and

     WHEREAS, this Addendum is intended only to affect those processes or
procedures as are necessary for Boston Beer to continue to brew and package its
Beer Products under an alternating proprietorship approved by the TTB at
Miller's breweries and is not intended to otherwise affect the existing
contractual relationship or the economic arrangement between the Parties;

     NOW, THEREFORE, in consideration of the mutual agreements contained in this
Addendum, the parties, intending to be legally bound, hereby agree as follows:

1.   It is the intention of the Parties that Miller will alternate
     proprietorship of Miller's brewery located in Eden, North Carolina (the
     "Eden Brewery") with Boston Beer so that Boston Beer will function as the
     brewer when the Beer Products are brewed and packaged at the Eden Brewery.
     Miller shall give Boston Beer access to the Eden Brewery and shall make
     available to Boston Beer its production personnel to allow Boston Beer to
     produce such volume of Boston Beer's proprietary Beer Products as has been
     agreed to by the Parties in the Agreement. All Beer Products shall be
     brewed and packaged according to Boston Beer's specifications, including
     the maintenance of standards and quality control programs. Boston Beer
     shall have ultimate responsibility and authority over every detail of the
     production process for Beer Products at the Brewery, with such
     responsibility and authority as to those


                                       -1-



     parameters affecting beer taste and quality to be the same as if Boston
     Beer were the owner of the Brewery. Boston Beer shall monitor and review
     the practices and procedures of Miller in the production and packaging of
     Beer Products and periodically inspect the Brewery. Miller acknowledges
     that Boston Beer shall be afforded unrestricted 24-hour access to the
     portion of the facility where Boston Beer's records are separately
     maintained and the warehouse area where Beer Products are stored, and shall
     be afforded access to the Miller facility during the time(s) that Boston
     Beer production requests are being processed. The Beer Products shall be
     separated and identifiable from the beer products by Miller for itself or
     other brewers at all stages, including prior to fermentation, during
     fermentation, during cellar storage and as finished beer after production
     and before removal from the Brewery.

2.   Miller has dedicated and will continue to maintain a space in the Eden
     Brewery where Boston Beer's records of operations and all other associated
     records are kept separate and apart from corresponding Miller records,
     pursuant to powers of attorney issued by Boston Beer to Miller employees.

3.   The Price paid by Boston Beer to Miller for allowing Boston Beer access to
     the Brewery and use of Miller's employees for the production of the Beer
     Products at the Brewery, includes compensation for Miller's employees,
     overhead, profit, and other costs, including lab tests, cleaning, brewing
     and filtration processing aids, packaging glues, shrink wrap, packaging
     process supplies and the like, incurred by Miller in the production of
     packaged Beer Products suitable for shipment by truck.

          (a)  The Price does not include the cost of raw materials (such as
               hops, malt and flavorings), ingredients and packaging materials
               used in the production of the Beer Products, which costs shall be
               borne directly by Boston Beer.

          (b)  Further, the Price excludes any federal and state excise taxes
               (but specifically excluding any taxes in the nature of a tax on
               income or profits), which shall be paid by Boston Beer.

4.   Miller shall issue a Bill of Sale in substantially the same form as
     attached hereto as Exhibit A for all raw materials, ingredients and other
     recipe materials used in the brewing of the Beer Products, including but
     not limited to hops, malt, and flavorings at the beginning of the
     manufacturing process, at which time title to all such brewing materials
     shall pass to and thereafter be the property solely and exclusively of
     Boston Beer and shall be segregated and identified as such at the brewery.
     The consideration for this sale and conveyance of the Production Materials
     will be incorporated into the lump sum charge to Boston Beer for the
     production of Beer Products at the Eden Brewery, which will be invoiced and
     paid by Boston Beer when the production of the malt beverage is completed
     pursuant to this Addendum and the underlying Production Agreement between
     Miller and Boston Beer.

5.   Boston Beer shall bear the risk of loss for the packaging materials, raw
     materials, ingredients and other recipe materials used by Boston Beer in
     producing the Beer


                                       -2-



     Products, Beer Products in process and finished goods, except where losses
     arise as a result of gross negligence or willful misconduct of Miller.

6.   It is understood that, consistent with the concept of an alternating
     proprietorship, Boston Beer's request to produce its Beer Products should
     not be referred to as "production orders" but, rather, "production
     requests." Therefore, wherever the words "minimum order" appears in the
     Agreement they shall be understood to mean "minimum production request."

7.   The Parties shall cooperate in taking such other actions, including
     modification of this Addendum, if so required by the TTB in order for
     Boston Beer to maintain its alternating proprietorship at the Eden Brewery.
     In the event Boston Beer is not able to maintain its alternating
     proprietorship or directly due to the Addendum, experiences a material
     adverse change in its costs to produce, package and ship its Beer Products
     at the Eden Brewery or such other Miller brewery where Boston Beer produces
     its Beer Products pursuant to the Agreement, Boston Beer may, in its sole
     discretion, terminate this Addendum to the Agreement upon thirty (30) days
     written notice to Miller.

8.   In the event that Miller exercises its right to transfer the production of
     the Beer Products to another brewery in accordance with the terms of the
     Agreement, the terms and conditions of this Addendum shall apply to such
     brewery.

9.   Except for the changes enumerated above, all other terms and conditions of
     the Agreement shall remain in full force and effect.

     IN WITNESS WHEREOF, Miller and Boston Beer have executed this Addendum to
the Agreement as of the date first above written.
