EXHIBIT 99.7






                            MEDIA LOGIC, INC.

                                   AND

                            ADAR EQUITIES LLC

 
                            WARRANT AGREEMENT



                       Dated as of March 25, 1997




  WARRANT AGREEMENT, dated as of March 25, 1997 by and between MEDIA LOGIC, 
INC., a Massachusetts corporation (the "Company"), and ADAR EQUITIES LLC (the 
"ADAR").

    The Company proposes to issue to ADAR 900,000 warrants as hereinafter 
described (the "Warrants") to purchase shares (the "Shares") of common stock 
of the Company, $.01 par value per share ("Common Stock"), each Warrant 
entitling the holder ("Holder") thereof to purchase one share of Common Stock.

    NOW, THEREFORE, in consideration of the premises and the mutual 
agreements set forth herein and for other good and valuable consideration, 
the receipt and sufficiency of which is hereby acknowledged, the parties 
hereto agree as follows:

    1. Issuance of Warrants; Form of Warrant. On March 24, 1997, the Company 
shall issue, sell and deliver the Warrants to ADAR or its bona fide officers, 
principals or affiliates. The form of the Warrant and of the form of Election 
to Purchase to be attached thereto shall be substantially as set forth on 
Exhibit A attached hereto. The Warrants shall be executed on behalf of the 
Company by the manual or facsimile signature of the present or any future 
Chairman or Co-Chairman, President or any Vice President of the Company, 
under its corporate seal, affixed or in facsimile, and attested by the manual 
or facsimile signature of the present or any future Secretary or Assistant 
Secretary of the Company.

    2. Registration. The Warrants shall be numbered and shall be registered 
in a Warrant register (the "Warrant Register"). The Company shall be entitled 
to treat the registered holder of any Warrant on the Warrant Register as the 
owner in fact thereof for all purposes and shall not be bound to recognize 
any equitable or other claim to or interest in such Warrant on the part of 
any other person, and shall not be liable for any registration or transfer of 
Warrants which are registered or are to be registered in the name of a 
fiduciary or the nominee of a fiduciary unless made with the actual knowledge 
that a fiduciary or nominee is committing a breach of trust in requesting 
such registration or transfer, or with such knowledge of such facts that its 
participation therein amounts to bad faith. The Warrants shall be registered 
initially in the name of ADAR Equities LLC in such denominations are ADAR may 
request in writing to the Company; provided, however, that ADAR may designate 
that all or a portion of the Warrants be issued in varying amounts directly 
to its bona fide officers or principals and not to itself. Such designation 
will only be made by ADAR if it determines that such issuances would not 
violate the interpretation of the Board of Governors of the National 
Association of Securities Dealers, Inc. (the "NASD"), relating to the review 
of corporate financing arrangements.



    3. Transfer of Warrants. The Holder of a Warrant Certificate, by its 
acceptance thereof, acknowledges that the Warrants are "restricted 
securities" which have not been registered under the Securities Act of 1933, 
as amended (the "Securities Act"), and represents that the Warrants are being 
acquired as an investment and not with a view to the distribution thereof and 
will not transfer such Warrants, except to bona fide officers, directors, 
shareholders, principals, employees or registered representatives of the 
Holder upon written request to the Company delivered in accordance with 
Section 12 hereof and upon delivery of the Warrant Certificate duly endorsed 
by the Holder or by his duly authorized attorney or representative, or 
accompanied by proper evidence of succession, assignment or authority to 
transfer. In all cases of transfer by an attorney, the original power of 
attorney, duly approved, or an official copy thereof, duly certified, shall 
be deposited with the Company. In case of transfer by executors, 
administrators, guardians or other legal representatives, duly authenticated 
evidence of their authority shall be produced, and may be required to be 
deposited with the Company in its discretion. Upon any registration of 
transfer, the Company shall deliver a new Warrant or Warrants to the persons 
entitled thereto. The Warrants may be exchanged at the option of the Holder 
thereof for other Warrants of different denominations, of like tenor and 
representing in the aggregate the right to purchase a like number of shares 
of Common Stock upon surrender to the Company or its duly authorized agent. 
The Company may require payment of a sum sufficient to cover all taxes and 
other governmental charges that may be imposed in connection with any 
voluntary transfer, exchange or other disposition of the Warrants. 
Notwithstanding the foregoing, the Company shall have no obligation to cause 
Warrants to be transferred on its books to any person, if such transfer would 
violate the Securities Act or applicable state securities laws.

    4. Exercise of Warrants; Term of Warrants.

       (a) Exercise of Warrants. Each Warrant entitles the registered owner 
  thereof to purchase one Share at a purchase price equal to $3.00 (the 
  "Exercise Price"). Subject to the provisions of this Agreement, each Holder 
  shall have the right, which may be exercised as set forth in such Warrants, 
  to purchase from the Company (and the Company shall issue and sell to such 
  Holder) the number of fully paid and nonassessable shares (rounded up to 
  the nearest full share) specified in such Warrants, upon surrender to the 
  Company, or its duly authorized agent, of such Warrants, with the form of 
  Election to Purchase attached thereto duly completed and signed, with 
  signatures guaranteed by a member firm of a national securities exchange, a 
  commercial bank (not a savings

                                   -2-



   
  bank or savings and loan association) or trust company located in the 
  United States or a member of the NASD and upon payment to the Company of 
  the Exercise Price for the number of Shares in respect of which such 
  Warrants are then exercised. Payment of such Exercise Price may be made in 
  cash or by certified check or official bank check payable to the order of 
  the Company. No adjustment shall be made for any dividends on any Shares 
  issuable upon exercise of a Warrant. Upon each surrender of Warrants and 
  payment of the Exercise Price as aforesaid, the Company shall issue and 
  cause to be delivered with all reasonable dispatch to or upon the written 
  order of the Holder of such Warrants and in such name or names as such 
  holder may designate, a certificate or certificates for the number of full 
  Shares so purchased upon the exercise of such Warrants. Such certificate or 
  certificates shall be deemed to have been issued and any person so 
  designated to be named therein shall be deemed to have become a holder of 
  record of such Shares as of the date of the surrender of Warrants and 
  payment of the Exercise Price as aforesaid; provided, however, that if, at 
  the date of surrender of Warrants and payment of such Exercise Price, the 
  transfer books for the Common Stock or other class of securities issuable 
  upon the exercise of such Warrants shall be closed, the certificates for 
  the Shares shall be issuable as of the date on which such books shall next 
  be opened and until such date the Company shall next be opened and until 
  such date the Company shall be under no duty to deliver any certificate for 
  such Shares; provided, further, however, that the transfer books of record, 
  unless otherwise required by law, shall not be closed at any one time for a 
  period longer than twenty (20) days. The rights of purchase represented by 
  the Warrants shall be exercisable, at the election of the Holder(s) 
  thereof, either in full or from time to time in part and, in the event that 
  any Warrant is exercised in respect of less than all of the Shares issuable 
  upon such exercise, a new Warrant or Warrants will be issued for the 
  remaining number of Shares specified in the Warrant so surrendered.

       (b) Term of Warrants. The Warrants granted pursuant to this Agreement 
  shall be exercisable from September 24, 1997 to March 24, 2002.

    5. Payment of Taxes. The Company will pay all documentary stamp taxes, if 
any, attributable to the issuance of Shares upon the exercise of Warrants; 
provided, however, that the Company shall not be required to pay any tax or 
taxes which may be payable in respect of any transfer involved in the issue 
or delivery of any certificates for Shares in a name other than that

                                    -3-





of the Holder of Warrants in respect of which such Shares are issued.

          6. Mutilated or Missing Warrants. In case any of the Warrants shall 
be mutilated, lost, stolen or destroyed, the Company shall issue and deliver 
in exchange and substitution for and upon cancellation of the mutilated 
Warrant, or in lieu of and substitution for the Warrant lost, stolen or 
destroyed, a new Warrant of like tenor and representing an equivalent right 
or interest, but only upon receipt of evidence reasonably satisfactory to the 
Company of such mutilation, loss, theft or destruction of such Warrant and 
indemnity, if requested, reasonably satisfactory to the Company. An applicant 
for such substitute Warrants shall also comply with such other reasonable 
regulations and pay such other reasonable charges and expenses as the Company 
may prescribe.

          7. Reservation of Shares, etc. There have been reserved, and the 
Company shall at all times keep reserved, out of the authorized and unissued 
Common Stock of the Company, a number of shares of Common Stock sufficient to 
provide for the exercise of the rights of purchase represented by the 
outstanding Warrants. American Stock Transfer & Trust Co., transfer agent for 
the Common Stock (the "Transfer Agent"), and every subsequent transfer agent, 
if any, for the Company's securities issuable upon the exercise of the 
Warrants will be irrevocably authorized and directed at all times to reserve 
such number of authorized and unissued shares as shall be required for such 
purpose. The Company will keep a copy of this Agreement on file with the 
Transfer Agent and with every subsequent transfer agent for any shares of the 
Company's securities issuable upon the exercise of the Warrants. The Company 
will supply the Transfer Agent or any subsequent transfer agent with duly 
executed certificates for such purpose. All Warrants surrendered in the 
exercise of the rights thereby evidenced shall be canceled, and such canceled 
Warrants shall constitute sufficient evidence of the number of Shares that 
have been issued upon the exercise of such Warrants.

          8. Reserved.

          9. Reserved.

          10. Registration Rights.

          (a) Demand Registration Rights. The Company covenants and agrees 
with ADAR and any other or subsequent Holders of the Registrable Securities 
(as defined in paragraph (f) of this Section 10) that, subject to the 
availability of audited financial statements which would comply with 
Regulation S-X under the Securities Act, upon written request of the then 
Holder(s) of at least a majority of the Warrants or the Registrable 
Securities, or both, which were originally issued to ADAR or its


                                       -4-





designees, made at any time within the period commencing one year and ending 
five years after the Closing Date, the Company will file as promptly as 
practicable and, in any event, within 60 days after receipt of such written 
request, at its expense (other than the fees of counsel and sales commissions 
for such Holders), no more than once, a post-effective amendment (the 
"Amendment") to a registration statement, or a new registration statement 
which shall be on Form S-3 if the Company is then eligible to use Form S-3, 
or a Regulation A Offering Statement (an "Offering Statement") under the 
Securities Act, registering or qualifying the Registrable Securities for 
sale. Within fifteen (15) days after receiving any such notice, the Company 
shall give notice to the other Holders of the Registrable Securities advising 
that the Company is proceeding with such Amendment, registration statement or 
Offering Statement and offering to include therein the Registrable Securities 
of such Holders. The Company shall not be obligated to any such other Holder 
unless such other Holder shall accept such offer by notice in writing to the 
Company within ten (10) days thereafter. The Company will use its best 
efforts, through its officers, directors, auditors and counsel in all matters 
necessary or advisable, to file and cause to become effective such Amendment, 
registration statement or Offering Statement as promptly as practicable and 
for a period of nine months thereafter to reflect in the Amendment, 
registration statement or Offering Statement financial statements which are 
prepared in accordance with Section 10(a)(3) of the Securities Act and any 
facts or events arising that, individually, or in the aggregate, represent a 
fundamental and/or material change in the information set forth in the 
Amendment, registration statement or Offering Statement to enable any Holders 
of the Warrants to either sell such Warrants or to exercise such Warrants and 
sell Shares, or to enable any holders of Shares to sell such Shares, during 
said nine-month period. If any registration pursuant to this paragraph (a) is 
an underwritten offering, the Holders of a majority of the Registrable 
Securities to be included in such registration shall be entitled to select 
the underwriter or managing underwriter (in the case of a syndicated 
offering) of such offering, subject to the Company's approval which shall not 
be unreasonably withheld.

         (b) Piggyback Registration Rights. The Company covenants and agrees 
with ADAR and any other Holders or subsequent Holders of the Registrable 
Securities that if, at any time within the period commencing one year and 
ending five years after the Closing Date, it proposes to file a registration 
statement or Offering Statement with respect to any class of equity or 
equity-related security (other than in connection with an offering to the 
Company's employees or in connection with an acquisition, merger or similar 
transaction) under the Securities Act in a primary registration on behalf of 
the Company and/or in a secondary registration on behalf of holders of such 
securities and the registration form or Offering Statement to be used may be

                                       -5-



used for registration of the Registrable Securities, the Company will give 
prompt written notice (which, in the case of a registration statement or 
notification pursuant to the exercise of demand registration rights other 
than those provided in Section 10(a) of this Agreement, shall be within ten 
(10) business days after the Company's receipt of notice of such exercise 
and, in any event, shall be at least 30 days prior to such filing) to the 
Holders of Registrable Securities (regardless of whether some of the Holders 
shall have theretofore availed themselves of the right provided in Section 
10(a) of this Agreement) at the addresses appearing on the records of the 
Company of its intention to file a registration statement or Offering 
Statement and will offer to include in such registration statement or 
Offering Statement all but not less than 40% of the Registrable Securities 
and limited, in the case of a Regulation A offering, to the amount of the 
available exemption, subject to paragraphs (i) and (ii) of this paragraph 
(b), such number of Registrable Securities with respect to which the Company 
has received written requests for inclusion therein within ten (10) days 
after the giving of notice by the Company. All registrations requested 
pursuant to this paragraph (b) are referred to herein as "Piggyback 
Registrations". All Piggyback Registrations pursuant to this paragraph (b) 
will be made solely at the Company's expense. This paragraph is not 
applicable to a registration statement filed by the Company with the 
Commission on Forms S-4 or S-8 or any successor forms.

              (i) Priority on Primary Registrations. If a Piggyback 
    Registration includes an underwritten primary registration on behalf of such
    Company and the underwriter(s) for such offering determines in good faith
    and advises the Company in writing that in its/their opinion the number of
    Registrable Securities requested to be included in such registration exceeds
    the number that can be sold in such offering without materially adversely
    affecting the distribution of such securities by the Company, the Company 
    will include in such registration (a) first, such number of securities that 
    the Company proposes to sell such that 40% of the Registrable Securities 
    requested to be included in such registration are included in the 
    registration and (b) second, securities of the holders of other securities 
    requesting registration.

              (ii) Priority on Secondary Registrations. If a Piggyback 
    Registration consists only of an underwritten secondary registration on 
    behalf of holders of securities of the Company (other than pursuant to 
    Section 10(a)), and the underwriter(s) for such offering advises the Company
    in writing that in its/their opinion the number of Registrable Securities 
    requested to be included in such registration 

                                       -6-



     exceeds the number which can be sold in such offering without materially 
     adversely affecting the distribution of such securities by the Company, the
     Company will include in such registration (A) first, the securities
     requested to be included therein by the holders requesting such
     registration and the Registrable Securities requested to be included in
     such registration, pro rata among all such holders on the basis of the
     number of shares requested to be included by each such holder, provided,
     however, the Company will use its best efforts to include not less than 40%
     of the Registrable Securities, and (B) second, other securities requested
     to be included in such registration.

         Notwithstanding the foregoing, if any such underwriter shall 
determine in good faith and advise the Company in writing that the 
distribution of the Registrable Securities requested to be included in the 
registration concurrently with the securities being registered by the Company 
would materially adversely affect the distribution of such securities by the 
Company, then the Holders of such Registrable Securities shall delay their 
offering and sale for such period ending on the earliest of (1) 90 days 
following the effective date of the Company's registration statement, (2) the 
day upon which the underwriting syndicate, if any, for such offering shall 
have been disbanded or, (3) such date as the Company, managing underwriter 
and Holders of Registrable Securities shall otherwise agree. In the event of 
such delay, the Company shall file such supplements, post-effective 
amendments and take any such other steps as may be necessary to permit such 
Holders to make their proposed offering and sale for a period of 120 days 
immediately following the end of such period of delay. If any part 
disapproves of the terms of any such underwriting, it may elect to withdraw 
therefrom by written notice to the Company, the underwriter, and ADAR. 
Notwithstanding the foregoing, the Company shall not be required to file a 
registration statement to include Shares pursuant to Sections 10(a) or 10(b) 
if independent counsel, reasonably satisfactory to counsel for the Company 
and counsel for ADAR, renders an opinion to the Company that the Shares 
proposed to be disposed of may be transferred pursuant to the provisions of 
Rule 144 under the Securities Act or otherwise without registration under the 
Securities Act.

         (c) Other Registration Rights. In addition to the rights above 
provided, the Company will cooperate with the then Holders of the Registrable 
Securities in preparing and signing any registration statement or Offering 
Statement, in addition to the registration statements and Offering Statements 
discussed above, required in order to sell or transfer the Registrable 
Securities and will supply all information required therefor, but such 
additional registration statement or Offering Statement, shall be at the then 
Holders' cost and expense; provided, however, that if the Company elects to 
register or qualify

                                       -7-



additional shares of Common Stock, the cost and expense of such registration 
statement or Offering Statement will be pro rated between the Company and the 
Holders of the Registrable Securities according to the aggregate sales price 
of the securities being issued. Notwithstanding the foregoing, the Company 
will not be required to file a registration statement or Offering Statement 
pursuant to this paragraph (c), (i) at a time when the audited financial 
statements required to be included therein are not available, which time 
shall be limited to the period commencing 45 days after the end of the 
Company's last fiscal year and ending 90 days after the end of such fiscal 
year, (ii) within 90 days after completion of a public offering by the 
Company of any of its Common Stock or equity-related securities or (iii) if 
it would adversely impact the Company in its capital raising plans or 
otherwise (in which latter case filing may be delayed no longer than 120 
days).

     (d) Action to be Taken by the Company. In connection with the 
registration of Registrable Securities in accordance with paragraphs (a), (b) 
or (c) of this Section 10, the Company agrees to:

          (i) Bear the expense of any registration or qualification under 
     paragraphs (a) or (b) of this Section 10, including, but not limited to, 
     legal, accounting and printing fees; provided, however, that in no event 
     shall the Company be obligated to pay (A) any fees and disbursements of 
     special counsel for Holders of Registrable Securities, or (B) any 
     underwriters' discount or commission in respect of such Registrable 
     Securities, (C) any stock transfer taxes attributable to the sale of the 
     Registrable Securities, or (D) upon the exercise of any demand 
     registration right provided for in paragraph (a) of this Section 10, the 
     cost of any liability or similar insurance required by an underwriter, 
     to the extent that such costs are attributable solely to the offering of 
     such Registrable Securities, payment of which shall, in each case, be 
     the sole responsibility of the Holders of the Registrable Securities.

          (ii) Use its best efforts to register or qualify the Registrable 
     Securities for offer or sale under state securities or Blue Sky laws of 
     such jurisdictions in which ADAR or such Holders shall reasonably 
     request, provided, however, that no qualification shall be required in 
     any jurisdiction where, as a result thereof, the Company would be 
     subject to service of general process or to taxation as a foreign 
     corporation doing business in such jurisdiction to which it is not then 
     subject, and to do any and all other acts and things which may be 
     necessary or advisable to enable the holders to consummate the proposed 
     sale, transfer

                                        -8-



     or other disposition of such securities in any jurisdiction; and

          (iii) Enter into a cross-indemnity agreement, in customary form, 
     with each underwriter, if any, and each holder of securities included in 
     such Amendment, registration statement or Offering Statement.

     (e) Action to be Taken by the Holders. In connection with the 
registration of Registrable Securities in accordance with paragraphs (a), (b) 
or (c) of this Section 10, the Company's obligation shall be conditioned as 
to each such public offering upon a timely receipt by the Company in writing 
of:

          (i) Information as to the terms of such public offering furnished 
     by or on behalf of each Holder intending to make a public offering of 
     his, her or its Registrable Securities; and

          (ii) Such other information as the Company may reasonably require 
     from such Holders, or any underwriter for any of them, for inclusion in 
     such registration statement or Notification on Form 1-A.

     (f) For purposes of this Section 10, (i) the term "Holder" shall include 
holders of Shares, and (ii) the term "Registrable Securities" shall mean the 
Shares, if issued.

     11. Notices to Holders.

     (a) Nothing contained in this Agreement or in any of the Warrants shall 
be construed as conferring upon the Holders thereof the right to vote or to 
receive dividends or to consent or to receive notice as shareholders in 
respect of the meetings of shareholders or the election of directors of the 
Company or any other matter, or any rights whatsoever as shareholders of the 
Company; provided, however, that in the event that a meeting of shareholders 
shall be called to consider and take action on a proposal for the voluntary 
dissolution of the Company, other than in connection with a consolidation, 
merger or sale of all, or substantially all, of its property, assets, 
business and good will as an entirety, then and in that event the Company 
shall cause a notice thereof to be sent by first-class mail, postage prepaid, 
at least twenty (20) days prior to the date fixed as a record date or the 
date of closing the transfer books in relation to such meeting, to each 
registered Holder of Warrants at such Holder's address appearing on the 
Warrant Register; but failure to mail or to receive such notice or any defect 
therein or in the mailing thereof shall not affect the validity of any action 
taken in connection with such voluntary dissolution.

                                       -9-




     (b) In the event the Company intends to make any distribution on its 
Common Stock (or other securities which may be issuable in lieu thereof upon 
the exercise of Warrants), including, without limitation, any such 
distribution to be made in connection with a consolidation or merger in which 
the Company is the continuing corporation, or to issue subscription rights or 
warrants to holders of its Common Stock, the Company shall cause a notice of 
its intention to make such distribution to be sent by first-class mail, 
postage prepaid, at least twenty (20) days prior to the date fixed as a 
record date or the date of closing the transfer books in relation to such 
distribution, to each registered Holder of Warrants at such Holder's address 
appearing on the Warrant Register, but failure to mail or to receive such 
notice or any defect therein or in the mailing thereof shall not affect the 
validity of any action taken in connection with such distribution.

     12. Notices. Any notice pursuant to this Agreement to be given or made 
by the Holder of any Warrant and/or the holder of any Share to or on the 
Company shall be sufficiently given or made if sent by first-class mail,

     This Warrant Certificate is subject to, and entitled to the benefits of, 
all of the terms, provisions and conditions of the Warrant Agreement, which

     This Warrant Certificate, with or without other Warrant Certificates, 
upon surrender at the principal office of the Company, may be exchanged for

     No holder of this Warrant Certificate shall be entitled to vote, receive 
dividends, subscription rights or be deemed the holder of Common Stock or any 
other securities of the Company which may at any time be issuable on the 
exercise hereof for any purpose, nor shall anything contained in the Warrant

herein be construed to confer upon the holder hereof, as such, any of the 
rights of a stockholder of the Company or any right to vote for the election 
of directors or upon any matter submitted to stockholders at any meeting 
thereof, or to give or withhold consent to any corporate action (whether upon 
any recapitalization, issue of stock, reclassification of stock, change of 
par value or change of stock to no par value, consolidation, merger, 
conveyance, or otherwise) or, except as provided in the Warrant Agreement, to 
receive notice of meetings, until the Warrant or Warrants evidenced by this 
Warrant Certificate shall have been exercised and the Shares shall have 
become deliverable as provided in the Warrant Agreement.

     If this Warrant shall be surrendered for exercise within any period 
during which the transfer books for the Company's Common Stock or other class 
of stock purchasable upon the exercise of this Warrant are closed for any 
purpose, the Company shall not be required to make delivery of certificates 
for shares purchasable upon such exercise until the date of the reopening of 
said transfer books, provided, however, that such books shall not be closed 
for longer than a 20-day period.

     IN WITNESS WHEREOF, THE COMPANY has caused the signature (or facsimile 
signature) of its President and its Secretary or Assistant Secretary to be 
printed hereon and its corporate seal (or facsimile) to be printed hereon.
