THE BOSTON BEER COMPANY, INC. AND SUBSIDIARIES

FORM 10-K

For The Period Ended December 25, 2004

PART I

General

The Boston Beer Company, Inc. (“Boston Beer” or the “Company”) is the largest craft brewer and the sixth largest brewer overall in the United States. In fiscal 2004, Boston Beer sold 1,258,206 barrels of its proprietary products (“core brands”) and brewed 8,999 barrels under contract (“non-core products”) for third parties.

During 2004, the Company sold a total of fifteen beers under the Samuel Adams® brand name, three flavored malt beverage products under the Twisted Tea® brand name, and one cider product under the HardCore® Cider brand name. Boston Beer produces malt beverages and hard cider products at Company-owned breweries and under contract. The Company-owned breweries are located in Cincinnati, Ohio and Boston, Massachusetts. The Company also brewed its beer under contract at three breweries during 2004 (located in Eden, North Carolina; Rochester, New York; and La Crosse, Wisconsin).

The Company’s principal executive offices are located at 75 Arlington Street, 5th Floor, Boston, Massachusetts 02116, and its telephone number is (617) 368-5000.

Beer Industry Background

The Company’s beer products are primarily positioned in the “Better Beer” category of the beer industry, which includes craft or specialty beers and most imports. Better Beers are determined by higher price, quality, image and taste, as compared with regular domestic beers. Samuel Adams® is the third largest brand in the Better Beer category of the United States brewing industry, trailing only Heineken® and Corona®.

The Company believes that the Better Beer category is approximately 15% of United States beer consumption and has experienced high single-digit compounded annual growth over the last ten years. During 2004, the Better Beer category experienced mid single-digit growth.

Before Prohibition, the United States beer industry consisted of hundreds of small breweries that brewed full-flavored beers. Since the end of Prohibition, most domestic brewers have shifted production to less flavorful, lighter beers, which use lower-cost ingredients, and can be mass-produced to take advantage of economies of scale in production and advertising. This shift towards mass-produced beers has coincided with consolidation in the beer industry. Today, the three major brewers (Anheuser-Busch, Inc., SAB Miller PLC, and Coors Brewing Company) comprise over 90% of all United States domestic beer production, excluding imports. Further, these three major brewers have all entered the Better Beer category, either by developing their own beers, acquiring, in whole or part, existing craft brewers or by importing and distributing foreign brewers’ brands.

The domestic beer industry, excluding Better Beers, has experienced a slight decline in shipments over the last ten years. During the past 10 years, domestic light beers, which are beers with fewer calories than the brewers’ traditional beers, have experienced significant growth within the category, and now have a higher market share than traditional beers.

During 2004, the total beer industry in the United States experienced low growth in volume of less than 1 %. The Company believes that this slower growth is due to both declining alcohol consumption per person in the population as well as increased competition from wine and spirits companies.

Narrative Description of Business

The Company’s business goal is to become the leading brewer in the Better Beer category by creating and offering high quality full-flavored beers. With the support of a large, well-trained sales organization, the Company strives to achieve this goal by increasing brand awareness through advertising, point-of-sale and promotional programs.

The Company’s product strategy is to create and offer a world-class variety of traditional beers and other alcoholic beverages with a focus on promoting the Samuel Adams® product line. In most markets, the Company focuses its advertising and promotional dollars on Samuel Adams Boston Lager®, Sam Adams Light® and Samuel Adams® Seasonal Beers.

The Samuel Adams® Brewmaster’s Collection is an important part of the Company’s portfolio and heritage, but does not receive separate promotional support. The Twisted Tea® brand family has grown each year since the product was first introduced and has established a strong consumer following in several markets. The Company plans to grow the brand further by continuing to promote the Twisted Tea® family in these markets. The Limited Edition Beers are produced at select times during the year in limited quantities and are sold at a higher price than the Company’s other products. The following is a list of continuing styles as of December 25, 2004:

Certain products may be produced at select times during the year solely for inclusion in the Company’s variety packs. During 2004, Samuel Adams® Cranberry Lambic, Old Fezziwig® and Holiday Porter were produced and included in the Samuel Adams® Winter Classics variety pack, and Samuel Adams® Scotch Ale was produced and included in the Samuel Adams® Brewmaster’s Collection Mix Pack.

The Company continually evaluates the performance of its various beers, flavored malt beverages, and hard cider styles and the rationalization of its product line, as a whole. The Company is committed to remaining a leading innovator in the Better Beer category by developing new products that allow the Samuel Adams® drinker to try new styles of malt beverages.

The Company sells its products to a network of approximately 415 wholesale distributors, who then sell to retailers such as pubs, restaurants, grocery chains, package stores, stadiums and other retail outlets. With few exceptions, the Company’s products are not the primary brands in distributors’ portfolios. Thus, the Company, in addition to competing with other malt beverages for a share of the consumer’s business, competes with other brewers for a share of the distributor’s attention, time, and selling efforts.

The Company sells its products predominantly in the United States, but also has markets in Canada, Europe, the Caribbean, and the Pacific Rim. During 2004, the Company’s largest distributor accounted for approximately 5% of the Company’s net sales. The top three distributors accounted for approximately 9%, collectively. In some states, the terms of the Company’s contracts with its distributors may be affected by laws that restrict the enforcement of some contract terms, especially those related to the Company’s right to terminate the services of its distributors. The Company typically receives orders in the first week of a month for products to be shipped the following month. Products are shipped within days of completion and, accordingly, there has historically not been any significant product order backlog.

During 2004, Boston Beer sold its products through a sales force of approximately 180 people, which the Company believes is one of the largest in the domestic beer industry. The Company’s sales organization is designed to develop and strengthen relations at each level of the three-tier distribution system by providing educational and promotional programs encompassing distributors, retailers, and consumers. The Company’s sales force has a high level of product knowledge and is trained in the details of the brewing and the selling processes. Sales representatives typically carry hops, barley, and other samples to educate wholesale and retail buyers about the quality and taste of the Company’s beers. The Company has developed strong relationships with its distributors and retailers, many of which have benefited from the Company’s premium pricing strategy and growth.

The Company has also engaged in media campaigns, primarily television, radio, billboards and print. These media efforts are complemented by participation in sponsorships of cultural and community events, local beer festivals, industry-related trade shows, and promotional events at local establishments, to the extent permitted under local laws and regulations. The Company uses a wide array of point-of-sale items (banners, neons, umbrellas, glassware, display pieces, signs, and menu stands) designed to stimulate impulse sales and continued awareness.

The Company has been successful to date in obtaining sufficient quantities of the ingredients used in the production of its beers. These ingredients include:

Malt. The Company purchased the majority of malt used in the production of its beer from one major supplier during 2004. The two-row varieties of barley used in the Company’s malt are grown in the United States and Canada. In 2003, the barley crop in both the United States and Canada was below the ten-year averages for both volume and quality of crop, which had resulted in some barley shortages and increased prices. The 2004 barley crop is above average in terms of quality due to favorable environmental conditions and was purchased at competitive prices nearly flat to 2003. The Company believes that there are other malt vendors available that are capable of supplying its needs.

Hops. The Company uses Noble hops for its Samuel Adams® lagers. Noble hops are varieties from several specific growing areas recognized for superior taste and aroma properties and include Hallertau-Hallertauer, Tettnang-Tettnanger and Spalt-Spalter from Germany. Noble hops are rare and more expensive than most other varieties of hops. Traditional English hops, namely, East Kent Goldings and English Fuggles, are used in the Company’s ales. The Company enters into forward purchase commitments with two hops dealers, based on the Company’s projected future volumes and brewing needs. The dealers then contract with farmers to ensure that the Company’s needs are met. The contracts with the hop dealers are denominated in Euro or in British Pounds Sterling. The Company does not currently hedge these forward currency commitments. The crops harvested in 2004 were consistent with 20-year historical averages in terms of both quality and quantity for all hop varieties from Germany and the UK. The Company maintains over one year’s supply of essential hop varieties on-hand in order to limit the risk of an unexpected reduction in supply. The Company stores its hops in multiple cold storage warehouses to minimize the impact of a catastrophe at a single site.

Yeast. The Company maintains a supply of proprietary strains of yeast used in its breweries and supplies them to its contract brewers. Since these yeasts would be impossible to duplicate if destroyed, the Company maintains secure supplies in several locations. In addition, the Company’s contract brewers maintain a supply of yeasts that are reclaimed from the batches of brewed beer. The contract brewers are obligated by their production contracts to use the Company’s proprietary strains of yeasts only to brew the Company’s beers and such yeasts cannot be used without the Company’s approval to brew any other beers produced at the respective breweries.

Other Ingredients. The Company maintains competitive sources for the supply of other ingredients used in some of its specialty malt-based and cider products.

Packaging Materials. The Company maintains competitive sources for the supply of packaging materials, such as shipping cases, six-pack carriers and crowns. Currently, glass and labels are each supplied by a single source, although the Company believes that alternative suppliers are available. The Company enters into limited term supply agreements with certain vendors in order to receive preferential pricing.

The Company initiates bottles deposits and reuses some of the glass bottles that are returned pursuant to certain state bottle recycling laws and derives some economic benefit from this practice. The cost associated with reusing the glass varies, based on the costs of collection, sorting and handling, including arrangements with retailers, wholesalers and dealers in recycled products. There is no guarantee that the current economics relating to the use of returned glass will continue or that the Company will continue to reuse returnable bottles.

As of December 25, 2004, the Company employed eight brewmasters and retained a recognized brewing authority as a consulting brewmaster to assist in monitoring the Company’s contract brewing operations and controlling the production of its beers. Over 125 tests, tastings and evaluations are typically required to ensure that each batch of Samuel Adams® beer, Twisted Tea® flavored malt beverage, and Hardcore® hard cider conforms to the Company’s standards. The Company has on-site quality control labs at each brewery.

In order to ensure that its customers enjoy only the freshest beer, the Company includes a clearly legible “freshness” code on every bottle and keg of its Samuel Adams® products. Boston Beer was the first American brewer to use this practice.

The Company believes that its current strategy of combining brewery ownership with contract brewing, which utilizes the excess capacity of other breweries, provides the Company flexibility as well as quality and cost advantages over its competitors. The Company carefully selects breweries with (i) the capability of utilizing traditional brewing methods and (ii) first rate quality control capabilities throughout brewing,

fermentation, finishing and packaging. Furthermore, by brewing in multiple locations, the Company reduces its distribution costs and is better able to deliver fresher beer to its customers than other craft brewers with broad distribution from a single brewery.

The Company brews nearly half of its volume at a Company-owned brewery located in Cincinnati, Ohio (the “Cincinnati Brewery”). The Company believes that this brewery complements the contract breweries by providing greater flexibility for brewing production. While the Cincinnati Brewery produces all of the Company’s beer styles, it is the primary brewery for the production of most of the Company’s specialty and lower volume beers and hard cider production, as well as most of the flavored malt beverage production.

The Company uses its brewery located in Boston, Massachusetts (the “Boston Brewery”) to develop new types of innovative and traditional products and to supply, in limited quantities, beers for the local market. Product development entails researching market needs and competitive products, sample brewing, and market taste testing. All of the Company’s products are brewed at the Boston Brewery in the course of a year.

The Company believes that it has secured sufficient alternatives in the event that production at any of its contract brewing locations is interrupted or discontinued. Management is currently unaware of any issues that would preclude normal production at any of its contract brewing locations. The Company continues to evaluate the benefits of contract brewing versus brewery ownership, and it considers variables such as availability of production capacity, brewery quality control procedures, consistency of contract strategy with the Company’s brand strategies, and costs associated with contract brewing versus costs associated with brewery ownership. If the Company determines in the future that the benefits of brewery ownership outweigh the benefits of contract brewing, brewery ownership would involve significant capital investment which could exceed $50.0 million for the combination of purchase, expansion and improvement, or for original construction.

The Company currently has contracts to produce its products with the breweries described below. Under its contract brewing arrangements, the Company is charged a per unit rate for the production of its products at each of the breweries and bears the costs of raw materials, excise taxes and deposits for pallets and kegs and specialized equipment required to brew the Company’s beers.

High Falls Brewing Company, LLC. For the months of January through November 2004, the Company brewed its beer at a brewery located in Rochester, NY (the “Rochester Brewery”) under a contract with High Falls Brewing Company, LLC (“High Falls”). The contract entered into as of April 15, 2002 (the “2002 Production Agreement”) expired November 30, 2004. Effective December 1, 2004, the Company entered into a new production agreement.

Miller Brewing Company. In 2004, the Company brewed its beer at one brewery owned and operated by the Miller Brewing Company (“Miller”). Much of the Company’s west coast supply that had been produced in 2003 at the Tumwater, Washington (the “Tumwater Brewery”) until it closed as of July 1, 2003 was transferred to Miller’s brewery located in Eden, North Carolina (the “Eden Brewery”). Additionally, a portion of the Company’s east coast supply was also produced at the Eden Brewery.

In 2002, Miller filed with the American Arbitration Association a demand for arbitration with respect to its legal right to terminate its obligation to continue production for the Company prior to the expiration of its production agreement with the Company. In September 2003, an arbitration hearing was held and in October 2003 the arbitrators ruled that Miller was not entitled to early termination of the production agreement and that the agreement was to remain in full force and effect. Thus, Miller is obligated to continue to produce the Company’s products in accordance with the terms and conditions of the agreement. Additionally, Miller is obligated to assume the cost of incremental freight to the areas previously supplied by the Tumwater Brewery and the Stroh Brewery in Allentown, Pennsylvania for that production from the Eden Brewery.

City Brewing Company, LLC. In July 2002, the Company entered into a production agreement with City Brewing Company, LLC of La Crosse, Wisconsin, under which the Company is guaranteed the availability

of a certain volume through at least December 2012. The Company had modest levels of production at the La Crosse facility in 2004.

The Better Beer category within the United States beer market is highly competitive due to the gains in market share achieved by imported beers and the large number of craft brewers with similar pricing and target customers. Imported beers, such as Heineken® and Corona®, have gained market share and increased volumes within the growing Better Beer segment as they continue to compete aggressively in the United States. While the Company believes that it may benefit from the success of the imports, as they educate beer drinkers about the Better Beer segment and increase the pool of Better Beer drinkers, these import competitors may have substantially greater financial resources, marketing strength, and distribution networks than the Company. Large domestic brewers have developed or are developing niche brands within the Better Beer category and have acquired interests in small brewers to compete in the craft-brewed segment or in import brands to compete with imported beers. Further, in response to a recent trend towards low-carbohydrate diets, certain domestic brewers have also introduced or re-positioned beers that are low in carbohydrates, some of which have successfully gained market share at the expense of all other beers, including the Company’s products.

The Company also competes with other alcoholic beverages for consumer attention and consumption. In recent years, wines and spirits have become more competitively active in seeking beer consumption occasions and competing directly with beers. The Company monitors such activity and attempts to develop strategies which benefit from the trading up of the consumer and positions our beers competitively with wine and spirits.

The Company competes with other beer and alcoholic beverage companies within a three-tier distribution system. The Company competes for a share of the distributor’s attention, time and selling efforts. In retail establishments, the Company competes for shelf and tap space. From a consumer perspective, competition exists for brand acceptance and loyalty. The principal factors of competition in the Better Beer segment of the beer industry include product quality and taste, brand advertising, trade and consumer promotions, pricing, packaging, the development of new products, and perceived nutritional content.

The Company distributes its products through independent distributors who may also distribute competitors’ products. In recent years, certain brewers have introduced new contracts with their distributors. Such contracts impose requirements on distributors that are intended to maximize the wholesalers’ attention, time and selling efforts on that brewer’s products. These new contracts generally result in increased competition among brewers as the contracts may affect the manner in which a distributor allocates selling effort and investment to the brands included in its portfolio. The Company closely monitors these and other trends in its distributor network and develops programs and tactics intended to best position its products in the market.

The Company has certain competitive advantages over the regional craft brewers, as the Company’s contract brewing strategy provides greater flexibility, higher quality and lower initial capital costs, freeing up capital for other uses. In addition, use of contract brewers allows the Company’s beer to be brewed closer to major markets around the country, providing fresher beer to customers and affording lower transportation costs. The Company also believes that the Cincinnati Brewery complements its strategy of contract brewing while providing added flexibility of production. Additionally, the Company believes it has competitive advantages over imported beers, including lower transportation costs, higher product quality, a lack of import charges, and superior product freshness.

Alcoholic Beverage Regulation and Taxation

The manufacture and sale of alcoholic beverages is a highly regulated and taxed business. The Company’s operations are subject to more restrictive regulations and increased taxation by federal, state, and local governmental entities than are those of non-alcohol related beverage businesses. Federal, state, and local laws and regulations govern the production and distribution of beer, including permitting, licensing, trade

practices, labeling, advertising, marketing, distributor relationships, and related matters. Federal, state, and local governmental entities also levy various taxes, license fees, and other similar charges and may require bonds to ensure compliance with applicable laws and regulations. Failure by the Company to comply with applicable federal, state, or local laws and regulations could result in penalties, fees, suspension, or revocation of permits, licenses, or approvals. There can be no assurance that other or more restrictive laws, regulations or higher taxes will not be enacted in the future.

Under a federal regulation issued in late 2004, a reformulation of most flavored malt beverage products will be required so that, by the end of 2005, a greater proportion of the final alcohol content must be a product of brewing. The reformulation may affect the Company’s Twisted Tea® product line potentially in a number of ways: revenue, cost of goods, taste profile, consumer acceptance, future growth and profit potential, among others. Twisted Tea® products account for less than ten percent of the Company’s sales volume. The Company is evaluating alternatives for addressing the new regulation and currently believes that the requirement can be met without adversely affecting the taste profile of the products. The exact capital and operating costs of complying with this requirement are still being evaluated, as well as the potential impact on the taste profile resulting from the reformulation of the product.

The Company, through its wholly-owned subsidiary, Boston Beer Corporation, produces and sells its alcoholic beverages to distributors pursuant to a federal wholesaler’s basic permit, a federal brewer’s notice and a federal winery registration. Brewery and wholesale operations require various federal, state, and local licenses, permits, and approvals. In addition, some states prohibit any supplier, such as the Company, and/or wholesaler from holding an interest in any retailer. Violation of such regulations can result in the loss or revocation of existing licenses by the wholesaler, retailer, and/or the supplier. The loss or revocation of any existing licenses, permits, or approvals, and/or failure to obtain any additional or new licenses, could have a material adverse effect on the ability of the Company to conduct its business.

At the federal level, the Alcohol and Tobacco Tax and Trade Bureau of the U.S. Treasury Department (“TTB”), administers and enforces the federal laws and tax code provisions related to the production and taxation of alcohol products. Brewers are required to file an amended notice with the TTB in the event of a material change in the production process, production equipment, brewery’s location, brewery’s management, or a material change in the brewery’s ownership. The TTB permits and registrations can be suspended, revoked, or otherwise adversely affected for failure to pay tax, keep proper accounts, pay fees, bond premises, abide by federal alcoholic beverage production and distribution regulations, and to notify the TTB of any change. Permits, licenses, and approvals from state regulatory agencies can be revoked for many of the same reasons. The Company’s operations are subject to audit and inspection by the TTB at any time.

At the state and local level, some jurisdictions merely require notice of any material change in the operations, management, or ownership of the permit or licensee. Some jurisdictions require advance approvals and require that new licenses, permits, or approvals must be applied for and obtained in the event of a change in the management or ownership of the permit or licensee. State and local laws and regulations governing the sale of malt beverages and cider within a particular state by an out-of-state brewer or wholesaler vary from locale to locale.

Because of the many and various state and federal licensing and permitting requirements, there is a risk that one or more regulatory agencies could determine that the Company has not complied with applicable licensing or permitting regulations or has not maintained the approvals necessary for it to conduct business within its jurisdiction. There can be no assurance that any such regulatory action would not have a material adverse effect upon the Company or its operating results. The Company is not aware of any infraction of any of its licenses or permits which would materially impact its operations.

The federal government and all of the states levy excise taxes on alcoholic beverages, including beer. For brewers producing no more than 2.0 million barrels of malt beverages per calendar year, the federal excise tax is $7.00 per barrel on the first 60,000 barrels of malt beverages removed for consumption or sale during a calendar year, and $18.00 per barrel for each barrel in excess of 60,000. For brewers producing more than 2.0 million barrels of malt beverages for domestic consumption in a calendar year, the federal excise tax is $18.00 per barrel. The Company has been able to take advantage of this reduced tax on the first 60,000 barrels of its malt beverages produced. Individual states also impose excise taxes on alcoholic beverages in varying amounts, which have also been subject to change. The determination of who is responsible, the Company or the distributor, to bear the liability of these taxes varies by state. Twisted Tea® is classified as a beer and is taxed accordingly. In addition, the federal government and each of the states levy taxes on hard cider. The federal excise tax rate on qualifying hard cider is $7.00 per barrel.

Federal and state legislators routinely consider various proposals to impose additional excise taxes on the production and distribution of alcoholic beverages, including beer and hard cider. Further increases in excise taxes on beer and/or hard cider, if enacted, could result in a general reduction in sales for the affected products or in the profit realized from the sales of affected products.

The Company has obtained United States Trademark Registrations for several trademarks, including Samuel Adams®, Sam Adams®, the design logo of Samuel Adams®, Samuel Adams Boston Lager®, Samuel Adams Cherry Wheat®, Triple Bock®, Sam Adams Light®, Twisted Tea® and HardCore®. The Samuel Adams® trademark and the Samuel Adams Boston Lager® trademark (including the design logo of Samuel Adams) and other Company trademarks are also registered or registration is pending in various foreign countries. The Company regards its “Samuel Adams” family of trademarks and other trademarks as having substantial value and as being an important factor in the marketing of its products. The Company is not aware of any trademark infringements that could materially affect its current business or any prior claim to the trademarks that would prevent the Company from using such trademarks in its business. The Company’s policy is to pursue registration of its marks whenever appropriate and to vigorously oppose any infringements of its marks.

Environmental Regulations and Operating Considerations

The Company’s operations are subject to a variety of extensive and changing federal, state, and local environmental laws, regulations, and ordinances that govern activities or operations that may have adverse effects on human health or the environment. Such laws, regulations, or ordinances may impose liability for the cost of remediation, and for certain damages resulting from, sites of past releases of hazardous materials. The Company believes that it currently conducts, and in the past has conducted, its activities and operations in substantial compliance with applicable environmental laws, and believes that any costs arising from existing environmental laws will not have a material adverse effect on the Company’s financial condition or results of operations. However, there can be no assurance that environmental laws will not become more stringent in the future or that the Company will not incur costs in the future in order to comply with such laws.

The Company’s operations are subject to certain hazards and liability risks faced by all producers of alcoholic beverages, such as potential contamination of ingredients or products by bacteria or other external agents that may be wrongfully or accidentally introduced into products or packaging. The occurrence of such a problem could result in a costly product recall and serious damage to the Company’s reputation for product quality, as well as give rise to product liability claims. The Company and its contract brewers maintain insurance which the Company believes is sufficient to cover any product liability claims which might result from a contamination or other product liability with respect to its products.

As part of its efforts to be environmentally friendly, the Company has reused its glass bottles returned from certain states that have bottle deposit bills. The Company believes that it benefits economically from

washing and reusing these bottles which result in a lower cost than purchasing new glass, and that it benefits the environment by the reduction in landfill usage, the reduction of usage of raw materials, and the lower utility costs for reusing bottles versus producing new bottles. The economics of using recycled glass varies based on the cost of collection, sorting and handling, and may be affected by local regulation, retailer, distributor and glass dealer behavior. There is no guarantee that the current economics of using returned glass will continue, nor that the company will continue to do so.

Employees

During 2004, the Company employed approximately 370 people, of which approximately 66 at the Cincinnati Brewery were covered by collective bargaining agreements. The representation involves three labor unions, all of whose contracts were successfully renegotiated in 2002 and extended for an additional five years. The Company believes it maintains a good working relationship with all three labor unions and has no reason to believe that the good working relationship will not continue. The Company has experienced no work stoppages, or threatened work stoppages, and believes that its employee relations are good.

Other

The Company submitted the Section 12(a) CEO Certification to the New York Stock Exchange in accordance with the requirements of Section 303A of the NYSE Listed Company Manual. This Annual Report on Form 10-K contains at Exhibits 31.1 and 31.2 the certifications of the Chief Executive Officer and the Chief Financial Officer, respectively, in accordance with the requirements of Section 302 of the Sarbanes-Oxley Act of 2002. The Company makes available free of charge copies of its Annual Report on Form 10-K, as well as other reports required to be filed by Section 13(a) or 15(d) of the Securities Exchange Act of 1934, via the Internet at www.bostonbeer.com, or upon written request to Investor Relations, The Boston Beer Company, Inc., 75 Arlington Street, Boston, Massachusetts 02116.

The Company maintains its principal corporate offices and a brewery in Boston, Massachusetts, a brewery in Cincinnati, Ohio, and two sales offices in California. The Company believes that its facilities are adequate for its current needs and that suitable additional space will be available on commercially acceptable terms as required.

Two complaints against many producers of alcoholic beverages, including the Company, were filed in Ohio during the second quarter 2004 relating to advertising practices and underage consumption. The Company believes that in February 2005, similar complaints were filed in New York and in Wisconsin, each naming substantially the same defendants, including the Company. The suits allege that each defendant intentionally marketed its products to children and underage consumers and seeks an injunction and unspecified money damages on behalf of an undefined class of parents and guardians. These actions are in their earliest stages. The Company intends to vigorously defend this litigation, but it is not possible at this time to determine the impact on the Company.

In November 2004, Royal Insurance Company of America and its affiliate (“RICA”), the Company’s liability insurer during most of the period covered by the above-referenced complaints, filed a complaint for declaratory judgment in Ohio seeking the court’s declaration that RICA owes no duty to defend or indemnify the Company in the underlying actions. While the Company believes it is entitled to reimbursement of its defense costs and indemnification, it is not able to predict at this time the ultimate outcome of this dispute.

The Company is not a party to any other pending or threatened litigation, the outcome of which would be expected to have a material adverse effect upon its financial condition or its results of operations.

On October 19, 2004, the sole Class B Stockholder voted to amend the Company’s Non-Employee Director Stock Option Plan to increase the number of shares of Class A Common Stock issuable under the Plan by 150,000 shares to a total of 350,000 shares. In addition, on such date, the Class B Stockholder voted to amend the Company’s Employee Equity Incentive Plan to change the eligible compensation of a participating employee in the Investment Share Program of the Plan from ten percent (10%) of an Eligible Employee’s W-2 earnings to ten percent (10%) of an Eligible Employee’s regular annual salary and bonus paid in the prior year, but excluding income to such employee resulting from the exercise of options issued or investment shares purchased under the Plan.

There were no matters submitted to a vote of the holders of Class A Common Stock of the Company during the fourth quarter ended December 25, 2004.
