GRIFFIN ANNOUNCES ANNUAL DIVIDEND

NEW YORK, NEW YORK (November 20, 2013) Griffin Land & Nurseries, Inc. (Nasdaq: GRIF) (“Griffin”) announced today that its Board of Directors has declared an annual dividend of $0.20 per share on the Company’s common stock.  The dividend is payable on December 10, 2013 to stockholders of record at the close of business on December 3, 2013.  The Board’s decision to declare an annual dividend this year was based on Griffin’s cash flow during the fiscal year ending November 30, 2013 including its sale of undeveloped land in Windsor, Connecticut for a distribution warehouse expected to close this week and Griffin’s projections of its future cash flows over the next three fiscal years, including Griffin’s expected capital spending during those periods.  During the next three fiscal years, Griffin expects its real estate business to continue to have substantial capital spending for construction and leasing in the Lehigh Valley of Pennsylvania, as well as for continuing investments in tenant improvements, lease commissions and land improvements related to Griffin Land’s Connecticut real estate holdings.  Prospectively, Griffin expects to continue to consider the payment of an annual dividend late in the year based on that year’s results and cash flows and its estimated future cash requirements.

Griffin operates its real estate business, Griffin Land LLC, and Imperial Nurseries, Inc. (“Imperial”), its landscape nursery business.  Earlier this year, Griffin announced that it had entered into a letter of intent for the disposition of Imperial’s landscape nursery growing operations and a lease of Imperial’s growing facilities to a private company nursery grower. Negotiations on definitive agreements for that transaction are ongoing.  Griffin also has an investment in Centaur Media plc, a public company based in the United Kingdom and listed on the London Stock Exchange.
