        Re: Amendment to Extend the Exercise Period of Vested Stock Options

Dear John:

        This letter agreement (the "Letter Agreement") sets forth the
understanding by and between you and Griffin Industrial Realty, Inc. (f/k/a
Griffin Land & Nurseries, Inc.), a Delaware corporation (the "Company"),
regarding the exercise period with respect to your options to purchase an
aggregate of 3,730 shares of the Company's common stock, par value $0.001 per
share (such options, the "Options") pursuant to the 2009 Stock Option Plan, as
amended (the "Stock Option Plan"), and those certain Non-Qualified Stock Option
Agreements by and between the Company and you, dated as of November 13, 2012 and
May 14, 2013 (the "Stock Option Agreements") following your Termination of
Directorship (as defined in the applicable Stock Option Agreement) on May 12,
2015. For the avoidance of doubt, this Letter Agreement does not apply to your
option granted pursuant to that certain Non-Qualified Stock Option Agreement by
and between the Company and you, dated as of May 13, 2014. Capitalized terms not
defined herein shall have the meanings given to such terms in the Stock Option
Plan.

        1.     As you are aware, Section 3.3 of each Stock Option Agreement
provides that the Options will expire three (3) months following the date of
your Termination of Directorship. Notwithstanding the foregoing, the Board has
amended the Options to provide that the Option granted under each Stock Option
Agreement shall remain exercisable until the tenth anniversary of the date such
Option was granted pursuant to the Board's authority to amend or modify the
terms of the Options pursuant to Section 5.4 of the Stock Option Plan and
Section 5.8 of each Stock Option Agreement. Thus, unless exercised sooner, your
Option to purchase 2,378 shares granted on November 13, 2012 will expire
November 12, 2022 and your Option to purchase 1,352 shares granted on May 14,
2013 will expire May 13, 2023.

        2.     In order to effectuate the foregoing, you agree to execute any
additional documents as may be reasonably requested from time to time by the
Company.

        3.     This Letter Agreement (together with the Stock Option Plan and
the Stock Option Agreements) sets forth the entire agreement between you and the
Company with respect to the Options. Except as otherwise set forth in this
Letter Agreement, the terms of the Stock Option Agreements will remain in full
force and effect after the date hereof.

        Please indicate your acceptance of the terms and provisions of this
Letter Agreement by signing both copies of this Letter Agreement and returning
one copy of each to me. The other copy is for your files. By signing below, you
acknowledge and agree that you have carefully read this Letter Agreement in its
entirety; fully understand and agree to its terms and provisions; and intend and
agree that the Letter Agreement is final and legally binding on you and the
Company. This Letter Agreement shall be

--------------------------------------------------------------------------------

administered, interpreted and enforced under the internal laws of the State of
Delaware without regard to conflict of laws thereof and may be executed in
several counterparts.

    Very truly yours,
 
 
/s/ MICHAEL S. GAMZON

Michael S. Gamzon
President and Chief Operating Officer

        Agreed, Acknowledged and Accepted as of the first date set forth above:
