                                                                 March 24, 1997

7% Convertible Subordinated Debenture Due 2000
Due March 24, 2000

    MEDIA LOGIC, INC., a Massachusetts corporation (the "Company"), for value 
received, promises to pay to _________________________________________________
_____________ or registered assigns on March 24, 2000, based on a principal 
amount of ________________ Dollars ($ _______),  shares of Common Stock of the
Company at the then-current conversion price, unless sooner prepaid or converted
into shares of Common Stock of the Company, together with accrued and unpaid
interest from the date of issue hereof.

    The Company promises to pay interest on the principal amount of this 
Debenture at the rate per annum of $700 per $10,000 Debenture (equal to seven 
percent of the aggregate principal amount of  a $10,000 Debenture).  Interest 
is payable only in accordance with applicable law and only upon conversion or 
redemption of the Debentures and is payable either in shares (the "Interest 
Shares") of Common Stock of the Company, par value $.01 per share (the 
"Common Stock"), at the average Market Price of the Common Stock over the 
five trading-day period preceding the Conversion Date of the Debenture or in 
cash, at the option of the Company.  Interest on the Debentures will accrue 
from the date of issuance.  Interest will be computed on the basis of a 
360-day year of twelve 30-day months.


    The Debentures will mature on March 24, 2000 and shall automatically 
convert on such date into Conversion Shares at the then-current Conversion 
Price.

    The Company has issued this Debenture under a Subscription Agreement 
between the Company and the Purchaser named therein (the "Subscription 
Agreement").  Capitalized terms herein are used as defined in the 
Subscription Agreement unless otherwise defined herein.  The terms of the 
Debentures include those stated in the Subscription Agreement, which are 
incorporated herein by reference.  The Debentures are subject to all such 
terms, and the Holder is referred to the Subscription Agreement for a 
statement of them.

    The Debentures are general unsecured obligations of the Company limited 
to $4,000,000 aggregate principal amount plus interest and penalty payments.

    This Debenture may be converted into shares of Common Stock of the 
Company as provided in Section 9 of the Subscription Agreement.  The 
Debenture is subordinated to all Senior Indebtedness of the Company.

    The Company will characterize the Debentures as preferred stock of the 
Company for federal income tax purposes.  Pursuant to Section 385(c) of the 
Internal Revenue Code of 1986, as amended, this characterization is binding 
on all Holders.  A Holder treating the Debenture in a manner inconsistent 
with such characterization must disclose the inconsistent treatment on such 
Holder's tax return.  This characterization, however, is not binding on the 
Internal Revenue Service, and neither the Company nor the Holder is excused 
from any interest or penalties resulting from improper characterization.

    The Company will furnish to any Holder upon written request and without 
charge a copy of the Subscription Agreement.  It also will furnish the text 
of this Debenture in larger type.  Requests may be made to Media Logic, Inc., 
310 South Street, Plainville, Massachusetts  02762,  Attention:  President.

    This Debenture shall be governed and construed in accordance with the 
laws of the State of New York.

    EXECUTED as an instrument under seal this 24th day of March, 1997.
