Jonathan Schull

Dear Jonathan:

         SoftLock.com, Inc. (the "Company") makes the following offer to you in
recognition of your past service to the Company and your agreement to act as the
President and Chief Executive Officer of the Company:

         1.       The Company shall pay you a monthly salary of fourteen
                  thousand five hundred eighty-three and 33/100 dollars
                  ($14,583.33).

         2.       The Company shall continue to provide to you all of the
                  benefits that you currently receive as an employee of the
                  Company for so long as the Company's benefit plans remain
                  available to the Company, and the Company shall use
                  commercially reasonable efforts to continue such benefit plans
                  for the duration of your employment.

         3.       You hereby agree that the Company has no obligations to you
                  for compensation or benefits other than for the compensation
                  and benefits that are described herein. You hereby waive all
                  claims against the Company for compensation and benefits other
                  than those claims relating to the compensation and the
                  benefits that the Company has agreed to provide to you herein.

         4.       You agree to act as the President and Chief Executive Officer
                  for a term (the "Term") of thirty (30) days, after which your
                  employment as President and Chief Executive Officer will be
                  at-will. You agree to serve on the Board of Directors of the
                  Company for so long as you remain employed by the Company in
                  any capacity.

         5.       The Company will continue to indemnify you as a director and
                  executive officer of the Company consistent with the Company's
                  by-laws. The Company agrees to make its best efforts to cause
                  the Company's Certificate of Incorporation to be amended to
                  add the language contained in EXHIBIT A attached hereto. The
                  Company shall make all commercially reasonable efforts to
                  obtain director and officer insurance. The Company shall not
                  be obligated to purchase such insurance other than at
                  commercially reasonable rates. The Company shall purchase the
                  extension of the current director and officer insurance
                  policy.

         6.       The Company shall pay you on the first business day following
                  the signing of the Letter of Intent, an amount of one hundred
                  fifty thousand dollars ($150,000). In consideration therefor,
                  you hereby waive all claims against the Company for
                  compensation and benefits other than those claims relating to
                  the compensation and the benefits that the Company has agreed
                  to provide to you herein.

         7.       The Company will cancel or otherwise terminate that certain
                  non-recourse promissory note (the "Note") from you to the
                  Company, dated June 22, 1996, in the principal amount of two
                  hundred fifty-five thousand nine hundred twenty dollars
                  ($255,920), plus any accrued interest. You hereby agree that
                  all of the shares that secure the Note will be delivered to
                  the Company and cancelled in consideration of the cancellation
                  or termination of said Note. The Company will endeavor in good
                  faith to structure this transaction to maximize the tax
                  efficiencies for you so long as they do not adversely affect
                  the Company.

         8.       Consistent with the recommendations of the Company's legal
                  advisors and with the consent of all of the Company's
                  preferred shareholders, as required, the Company will
                  establish an executive incentive compensation plan that will

         10.      You hereby acknowledge that you are party to a non-competition
                  and non-disclosure agreement with the Company and that you
                  continue to remain bound by that agreement.

Re:      Engagement Agreement

Dear Jon:

In accordance with the Rules of Professional Conduct, which govern our providing
services as attorneys, this letter will confirm the basis on which Bramson &
Pressman ("B&P") have been asked to represent Softlock.com, Inc. d/b/a Digital
Goods ("Digital Goods") in connection with the sale or licensing of its patent
portfolio (the "Patent Portfolio"), and such other matters as you may request.

Our engagement will cover a period of up to two (2) years from the date of this
Engagement Agreement, and shall continue thereafter on a month-to-month basis,
subject to termination after six (6) months from the date hereof by either party
upon written notice. All compensation and arbitration provisions will survive
termination.

During the initial three (3) months of this engagement, we will undertake the
following tasks:

       1.   Preparing a new set of claims for filing by Digital Goods' patent
            counsel, coordinating our efforts with patent counsel, and otherwise
            working to put the Patent Portfolio in optimum condition for license
            or sale;

       2.   Developing a list of prospects for the sale or license of the Patent
            Portfolio;

       3.   Developing a strategy for the sale or license of the Patent
            Portfolio, working with Digital Goods to determine whether the
            strategy should be long-term or short-term;

       4.   Developing suitable marketing materials;

<PAGE>

Dr. Jonathan Schull

May 11, 2001

       5.   Contacting agreed-upon prospects and participating in negotiations
            with those prospects; and

       6.   Participating in a license or sale program.

Tasks 1, 5 and 6 may well continue beyond the initial three-month period.

During this engagement, B&P will be the sole and exclusive representative of
Digital Goods as to the sale or license of the Patent Portfolio. B&P will not
have the right to obligate Digital Goods in any contract without your written
consent. All decisions as to strategy and business terms will be made by Digital
Goods.

During this engagement, B&P will keep detailed records of time spent on behalf
of Digital Goods and will bill you for our services, subject to (i) a
thirty-five percent (35%) discount from our regular billing rates, which are
$350 per hour for me and $250 per hour for Robert A. Pressman, and (ii) a cap of
$7,500 per month on payments by Digital Goods (at the discounted rate);
provided, however, that B&P is not obligated to provide services in any month
valued at over $10,000 (at the discounted rate).

We will provide you with regular monthly bills, specifying time devoted to each
Digital Goods matter, and expect to be paid promptly after your receipt of our
bills.

This Engagement Agreement is subject to an evergreen retainer of $7,500. Upon
execution of this Engagement Agreement, Digital Goods will send $15,000 to B&P
by Federal Express, to be applied to its account. Whenever the account balance
falls below $7,500, Digital Goods will promptly make a payment to bring the
current balance back to $15,000.

In addition to the discounted fees, Digital Goods will pay B&P a success fee of
twelve-and-one-half percent (12 1/2%) of all "net revenues" received by Digital
Goods during or after the term of this Engagement Agreement, with respect to
transactions (including any patent infringement suits) involving all or any part
of the Patent Portfolio and entered into during the term of this Engagement
Agreement or within two (2) years thereafter ("net revenues" are gross revenues
minus out-of-pocket expenses of Digital Goods incurred in negotiating and
closing any transaction for the sale or license of the Patent Portfolio), except
that:

       1.   With respect to any patent infringement suit filed during the term
            of this Engagement Agreement, involving one or more patents in the
            Patent Portfolio, B&P's right to receive a success fee shall apply
            when the suit is concluded by final and unappealable judgment or
            settlement;

       2.   In the event of a transaction involving both the Patent Portfolio
            and significant other assets of Digital Goods, the parties shall
            endeavor in good faith to determine the relative contributions of
            the Patent Portfolio and the other assets to the total consideration
            paid in the transaction, and to adjust the success fee
            proportionately;

<PAGE>

Dr. Jonathan Schull
Page 3
May 11, 2001

            provided, hwoever, that in such event, the success fee will be in
            the range of 5% to 10%; and

       3.   Transactions during the two (2)-year post-termination period shall
            have been with companies with which B&P participated in
            presentations or other activities related to the sale or licensing
            of the Patent Portfolio.

B&P will bill Digital Goods, on a monthly basis, for any out-of-pocket expenses
which we incur on your behalf, such as long-distance telephone calls,
photocopying, express delivery services, and travel expenses. We will not incur
any monthly expenses in excess of $500 without your consent. We may request
advance payment for substantial expenses.

Digital Goods hereby grants to B&P a first and prior lien on and security
interest in the Patent Portfolio and the proceeds thereof, to secure the
payments due and owing to B&P under this Engagement Agreement, and will execute
and deliver such documents as B&P may request to evidence this right. If any
future investors in Digital Goods require a security interest in the Patent
Portfolio, B&P shall share its security interest and the proceeds thereof on a
PARI PASSU basis. If requested, B&P and the investors shall enter into an
agreement under which one of the parties shall hold the security interest for
the benefit of all of the parties. The foregoing lien is subject to existing
liens, if any. Digital Goods has no knowledge of any such liens.

B&P are attorneys and will be called upon to perform legal services in advising
Digital Goods about and negotiating and drafting agreements as to the Patent
Portfolio. You are hereby advised that the Pennsylvania Code of Professional
Responsibility may require attorneys to disclose to clients a possible conflict
of interest inherent in performing legal services for a content fee or taking an
interest in a client asset. You acknowledge that you have consulted with
independent counsel in entering into this Engagement Agreement. You hereby waive
any present or future claim that Digital Goods does or may have that B&P has a
conflict of interest as a result of its performing services hereunder for a
contingent fee or taking a security interest in the Patent Portfolio.

Any dispute between us that cannot be resolved amicably shall be decided by
arbitration, conducted in New York, New York, by a single arbitrator in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association. The arbitrator shall have at least twenty-five (25) years of
experience in the intellectual property field, including at least ten years of
extensive patent licensing experience, and a degree in electrical engineering,
computer science, or physics. The arbitrator shall award the prevailing party
the amount of its attorneys fees and expenses, in addition to any other sums to
which the prevailing party shall be entitled. The fees and expenses of the
arbitrator shall initially be divided equally between the parties, but shall be
included in the arbitrator's award of fees and expenses to the prevailing party.
Notwithstanding the foregoing, if the only issue to be decided in the
arbitration is the percentage amount of the applicable success fee, each party
shall pay (i) its own attorneys fees and expenses and (ii) one-half (1/2) of the
fees and expenses of the American Arbitration Association and of the arbitrator.

This is the entire agreement between us as to the Patent Portfolio, and its
validity and interpretation shall be governed by Pennsylvania law.

If the terms of this proposal meet with your approval, please sign this
Engagement Agreement in the space below, and provide me with a signed return
copy.

We look forward very much to working with you.

Sincerely yours,

Bramson & Pressman
