NOW THEREFORE IT HAS BEEN AGREED AS FOLLOWS:


Article 1: 3M Agreement

1-1  Nocopi agrees that Euro has a right to receive a proportionate share of any
     minimum royalties or consideration or their equivalent which have been
     received by Nocopi as of this date or which may be received by Nocopi in
     the future and in particular those payments due under paragraph 4.5.1 of
     the 3M Agreement.

1-2  Nocopi represents that since December 1, 1995, it has received payments
     under the 3M Agreement representing minimum royalties, termination charges
     and label production payments. Since April 1, 1997, minimum royalties have
     been received at the rate of $10,000 per month.

1-3  Nocopi and Euro agree that from and after April 1, 1997, Nocopi shall pay
     to Euro 35% of the said minimum royalties. For the contract period from
     December 1, 1995 to May 31, 1997, it will pay the sum of $151,000 (which
     includes the sum of $14,000 in late interest payments). For the period
     commencing on June 1, 1997, an additional sum of $3,500 for a total of USD
     154,500, due to Euro as of the date hereof. This sum will be paid in three
     equal installments, of $51,500 each payable on the first day of July 1997,
     October 1997 and January 1998. Each installment so due shall be deducted
     from the royalty payment of $62,500 due by Euro to Nocopi on these same
     dates pursuant to paragraph 3.03(i) of a certain License Agreement (the
     License Agreement) dated June 10, 1994 between said parties.

1-4  Concerning any payments received by Nocopi from 3M pursuant to paragraph
     4.5.1 of the 3M Agreement after the date of this agreement, Nocopi shall
     within 8 days after receipt thereof pay to Euro an amount equal to 35% of
     the amount so received. This payment shall be made by wire transfer to an
     account determined by Euro. No royalties shall be payable by Euro to Nocopi
     on 3M minimum royalties.

1-5  Nocopi agrees that Euro shall be entitled to receive all Running Charges on
     any Products (as these terms are defined in the 3M Agreement) which are
     sold or delivered or destined for sale or delivery in the Territory as this
     term is defined in the License Agreement, to the extent that such Running
     Charges exceed minimum royalty payments received by Euro.

1-6  Following such time as Euro makes arrangements for manufacture in Europe,
     the place of production of the Products for 3M and accordingly the identity
     of the party, Nocopi or Euro, entitled to receive handling, converting or
     other charges, shall unless otherwise agreed, be Euro if the place where
     the Products are destined to be sold or delivered is in Europe, otherwise
     it shall be Nocopi. For example, if an order is placed by Bosch Germany
     with 3M for labels, they will be produced by Euro in Europe and Euro will
     be entitled to receive all consideration related to manufacturing and
     marking the labels.

Article 2: Licensing/Contracts

2-1  In their efforts to market and sell the Nocopi Technology, Nocopi and Euro
     on occasion find it appropriate to propose contractual arrangements to
     customers which provide for the marking, sale, and use of products in
     Europe and the rest of the world. In order to enable a smooth working
     relationship and an equitable division of royalties and other revenues,
     Nocopi and Euro have agreed to establish certain principles which shall
     govern contracts (other than 3M with respect to which the provisions of
     Article 1 shall be controlling).

     o    Negotiations for exclusive or non-exclusive agreements in Europe shall
          be carried out by and be the sole responsibility of Euro;

     o    Negotiations for exclusive or non-exclusive agreements in the rest of
          the world (excluding Europe) shall be carried out by and be the sole
          responsibility of Nocopi;

     o    The party conducting the negotiations shall keep the other party fully
          and contemporaneously advised of all developments in the negotiations
          and shall copy the other party on all correspondence, memorandums,
          contracts, documents etc.

     o    No contract affecting Europe shall be signed unless Euro has approved
          the signature thereof on its behalf.

     o    With respect to world contracts, negotiations will first be carried
          out by representatives of both Euro and Nocopi; in the event that Euro
          and Nocopi are unable to agree between themselves as to the terms and
          conditions affecting each of their exclusive territories, then each
          may enter separately into an agreement relating to its territory.

     o    Handling, converting, servicing, technical assistance and similar
          revenues shall be apportioned equitably, on the basis of each party's
          contribution of relevant services.


Article 3: Warrants/Conversion

3-1  Nocopi is the owner of 12,500 warrants (called Bons de Souscsription
     Autonome or BSA of Euro, giving it the right to acquire 12,500 shares of
     Series A of Euro, for a period of five years commencing on June 17, 1994,
     and expiring on June 16, 1999, or at the time of a public offering by Euro
     on the quotation of the shares of Euro on a stock exchange, whichever is
     earlier.

3-2  Euro and Nocopi agree that exercise period for these BSA shall be modified
     to make them exercisable commencing only on January 1, 2001, for a period
     of one year ending on December 31, 2001, provided that these BSA shall be
     exercisable earlier in the event that Euro makes a public offering of its
     shares or is quoted on a stock market, or in the event an offer to sell any
     part or all of Euro is accepted by the Euro Board or by its shareholders.


                                      -3-

<PAGE>


     In the latter event the BSA shall be exercisable in the thirty day period
     preceding the public offering or stock market quotation, or sale subject to
     local regulations. In exchange for the deferral of exercisability of these
     BSA, Euro agrees it will not make any change to its articles of
     incorporation or to its bylaws without first obtaining the written consent
     of Nocopi during the deferral period.

3-3  The modification of the terms of exercise of the BSA is required to be
     submitted to the appropriate approval of the shareholders of Euro. Nocopi
     and, in the event they are shareholders or directors at the relevant time,
     Messrs. Gardner, Pinsky, Drake, Mundt and Gundjian agree to cast their
     votes as shareholders and directors in favor of said modification. The
     releases granted by Euro in Article 7 hereof are subject to the condition
     that these parties cast their votes as agreed.

3-4  Nocopi hereby agrees to defer to January 1, 2001, and the year ending
     December 31, 2001, the exercise of the Conversion call rights granted to it
     in paragraph 3-6 of an agreement entitled Shareholders Agreement-Conversion
     signed between Nocopi and each of the shareholders who participated in the
     increase in capital of Euro, decided by a shareholders extraordinary
     meeting of Euro dated June 17, 1994.

Article 4: Directors

     At the time of the signature of this agreement Nocopi will deliver to Euro
     the resignations of Messrs. Gardner, Pinsky, Mundt, Drake and Gundjian from
     their duties as members of the Board of Directors of Euro and the signed
     transfer documents for the assignment of all shares owned by these persons
     in Euro.

Article 5: Technical Assistance

5-1  Subject to license and technical service payments due from Euro being made
     on a timely basis, Nocopi hereby reiterates its undertaking to provide
     technical assistance to Euro on an on-going basis, and in particular the
     technical assistance described in paragraph 8.03 of the License Agreement.
     This technical assistance will be performed by Nocopi technical personnel
     as determined by Dr. Gundjian. When possible, Nocopi will endeavor to
     comply with Euro's reasonable requests for specific personnel. No technical
     assistance, trips or expenditures will be undertaken without the specific
     approval of Euro.

5-2  Nocopi agrees that it will cooperate in making Dr. Gundjian available to
     perform his services for Euro in Europe, as may be requested by the latter
     for up to 30 working days per year and a senior and/or junior technical
     assistant for up to 10 working days per year. Nocopi further agrees that
     Euro will pay the USD 1,000 per diem referred to in paragraph 5-3 directly
     to Dr. Gundjian as an annual salary or consulting fee of $30,000,
     commencing July 1, 1997, in lieu of payment to Nocopi, subject to Dr.
     Gundjian's agreement that his compensation from Nocopi may be reduced by
     this amount.


                                      -4-

<PAGE>


5-3  When technical assistance services are rendered in Europe, Euro shall pay
     reasonable travel, lodging and meals after receipt of adequate proof of
     expenditure, as well as a per diem charge for working days of USD 1,000 for
     Dr. Gundjian, USD 400 for a senior assistant, USD 200 for a junior
     assistant. It is agreed that Euro will pay air transportation tickets
     directly or by charge to its Carte Bleu and that it will pay hotel bills
     directly.

5-4  Under paragraph 8.03 of the License Agreement, Nocopi is required to
     provide technical assistance to Euro, without charge when rendered at
     Nocopi's premises. It had previously been agreed between the parties that
     Euro, in order to avoid the cost of creating its own laboratory would pay
     50% of the salary cost of a senior assistant and 100% of the salary cost of
     a junior assistant. This laboratory personnel is intended among other
     things to test the use of Nocopi Technology and inks on customer products.
     It is agreed that commencing April 1, 1997, and until such time as Euro
     installs its own laboratory, Euro will pay Nocopi 35% of Nocopi's U.S. lab
     costs, which costs shall be subject to review and audit by Euro. Euro's
     share shall be subject to a cap of USD 80,000 per year.

Article 6: Accounting

     Concerning inter-company accounts, Nocopi has submitted to Euro its version
     of these accounts. Euro contends that USD 54,805 is owed to it for
     1995-1996 concerning L'Oreal and Chanel and that it owes Nocopi no more
     than USD 49,101 for the first quarter of 1997 whereas Nocopi claims USD
     111,587 is owed to it for the first quarter of 1997, and a further $73,000
     for the months of April and May, 1997, as well as an amount of $38,000
     relating to Nocopi U.K. totaling approximately $220,000 based on statements
     provided to Euro. Euro agrees at the time of signing this agreement to pay
     Nocopi $150,000 on account with respect to such net inter-company accounts
     as may be determined to be payable with respect to inter-company items from
     January 1, 1997, to the date of this agreement. Representatives of Euro and
     Nocopi (most probably Dr. Gundjian and Susan Cox) shall meet as soon as
     possible after signing to reach agreement with respect to inter-company
     items. Failing agreement, Euro and Nocopi agree to seek the mediation of
     Coopers & Lybrand, Paris to settle any questions concerning these
     accounts. Each party shall be entitled to submit one or more written
     statements to Coopers & Lybrand who will be asked to render a written
     determination. If either party refuses to accept the determination of
     Coopers & Lybrand, it may within 30 days of receipt of the written
     determination submit the matter to the binding arbitration of the American
