AGREEMENT made this ________ day of January, 1993, by and between
________________________, a _______________ corporation (hereinafter called
"Licensor") ________________________________ and CEPHALON INC., a Delaware
corporation (hereinafter called "Licensee"), 145 Brandywine Parkway, West
Chester, PA 19380, U.S.A.

WITNESSETH:

WHEREAS, Licensee and Laboratoire Lafon ("LAFON") entered into an agreement
dated this day (hereinafter called the "License Agreement") in which Licensee
was granted an Exclusive License to make, have made, use and sell Licensed
Products (as defined herein) in the Territory (as defined herein); and

WHEREAS, Licensor warrants and represents that it is the sole owner of and has
the full right, title and interest in and to the Licensed Trademark (as defined
herein) in the Territory; and

WHEREAS, Licensor is interested in granting and Licensee is interested in
receiving an Exclusive License to use the Licensed Trademark in connection with
the sale of Licensed Product in the Territory.

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the
parties mutually agree as follows:

                            ARTICLE I - DEFINITIONS

Capitalized terms not otherwise defined herein shall have the same meaning
assigned to them in the License Agreement. For purposes of this Agreement the
following words and phrases shall have the following meanings:

1.   "Licensed Trademark" shall mean the word "___________" (to be completed
     later by the parties) or such other word or name as shall be agreed upon by
     the parties in writing which word or name is to be registered as a
     trademark in the Territory and owned by Licensor.

2.   "Licensed Product" shall mean any pharmaceutical specialty (whether sold by
     prescription, over-the-counter, or otherwise) containing the Compound.

3.   "Combination Product" shall mean any Licensed Product containing the
     Compound and one or more other pharmacologically active ingredients.

                                      -1-


4.   "Compound" shall mean Modafinil and/or other compounds, isomers or salts
     thereof.

5.   "Territory" shall mean the territory of U.S.A., its territories and
     possessions, and Mexico.

6.   "Net Sales" shall mean the gross proceeds derived by Licensee and/or its
     sublicensees from the sale of Licensed Product bearing the Licensed
     Trademark in the Territory while this Agreement is in effect, after
     deducting normal and customary cash and trade discounts, returns,
     allowances, transportation and insurance charges or allowances, if shown on
     the invoice for the sale, and sales, excise, turnover or similar taxes, if
     any paid or allowed by Licensee, or its sublicensees directly in respect of
     such sales. Net Sales for Combination Products shall be determined by
     multiplying the Net Sales of such Combination Product by a fraction; the
     numerator of the fraction shall be the cost to Licensee of the active
     substance supplied by Licensor, and the denominator shall be the total cost
     to Licensee of all active ingredients contained in such Combination Product
     but in no event shall the royalty be decreased to less than one-half (1/2)
     of the amount obtained in applying the royalty rate under Article III,
     Paragraph 1 below to the Net Sales of the Combination Product. Costs shall
     be determined according to Licensee's accounting methods for determining
     the cost of its pharmaceutical products.

7.   "Exclusive License" shall mean a license whereby Licensee's rights shall be
     sole and entire and shall operate to exclude all others including Licensor.

8.   "Licensee" shall mean Cephalon, Inc. and any entity controlled by Cephalon,
     including any subsidiary or other entity as to which Cephalon owns at least
     50% of the voting stock or the right to receive at least 50% of the
     profits.

                         ARTICLE II - GRANT OF LICENSE

1.   Licensor hereby grants to Licensee an Exclusive License to use the Licensed
     Trademark as a trademark for the Licensed Product in the Territory,
     including the right to grant sublicenses, subject to the terms and
     conditions of this Agreement. Licensee shall be liable to Licensor for the
     thorough application by its sublicensees of the obligations of its
     sublicensees hereunder.

2.   During the term of the License Agreement, Licensee agrees to promote and
     sell Licensed Product employing the Licensed Trademark, in the Territory;
     provided, however, Licensee may promote and sell Licensed Product solely by
     its generic drug designation without employing the Licensed Trademark when

                                      -2-


     such action is necessary in order to sell Licensed Product in compliance
     with governmental regulations or restrictions.

3.   Licensee shall to the extent reasonably possible use the Licensed Trademark
     on Combination Products giving consideration to the amount of Licensed
     Product in such Combination Product and other relevant business factors. In
     the event Licensee is unable to use the Licensed Trademark for a
     Combination Product, Licensee will under the terms of this Agreement sell
     such Combination Product using a registered trademark owned by Licensor in
     the Territory, provided that Licensor shall have granted to Licensee all
     rights necessary to so use such registered trademark.

                            ARTICLE III - ROYALTIES

1.   For and in consideration of the Exclusive License to use the Licensed
     Trademark granted herein, Licensee shall pay Licensor a royalty as follows:

     a)   during the first fifteen (15) years of the term of this Agreement,
          four percent (4%) of Net Sales; and

     b)   during the next succeeding five (5) years of the term of this
          Agreement, two percent (2%) of Net Sales.

     Thereafter, Licensee's license under Article II to use the Licensed
     Trademark shall be fully paid-up and irrevocable.

2.   Royalty payments shall be made in U.S. Dollars within sixty (60) days after
     the last day of June and December for royalties accruing on sales during
     the six (6) preceding calendar months. Each royalty payment shall be
     accompanied by a statement which shall set forth the gross sales, the
     detail of the deductions made according to Article I, Paragraph 5 above,
     and the Net Sales figure. If Licensee receives Net Sales in a currency
     other than US Dollars, royalties shall be calculated by using the rate for
     converting such currency into US Dollars quoted as the New York foreign
     exchange selling rate on the last business day of the royalty period.

3.   No royalties shall be payable on sales between Licensee and its
     sublicensees.

4.   All taxes assessed, imposed on or required to be withheld from royalty
     payments due Licensor, will be deducted from the sums due. Tax receipts
     will be received by Licensee evidencing such payments which receipts will
     be forwarded to Licensor.

                                      -3-


5.   Any sublicensee of the Licensee may pay on behalf of Licensee any
     obligation of Licensee under this Agreement and such payment shall be
     received by Licensor in lieu of payment by Licensee with the same effect as
     if payment had been tendered by Licensee in satisfaction of such obligation
     under this Agreement.

6.   Licensee shall, and shall require its sublicensees to, keep and maintain
     records of sales made pursuant to the license and/or sublicenses granted
     hereunder. Such records shall be open to inspection at any reasonable time
     and upon reasonable notice (but not more than once each calendar year)
     within three (3) years after the royalty period to which such records
     relate, by an independent certified public accountant selected by Licensor,
     retained at Licensor's expense and approved by Licensee, such approval not
     to be unreasonably withheld. Such accountant shall have the right to
     examine the records kept pursuant to this Agreement only to verify the
     royalty payments to be made by Licensee to Licensor hereunder. Such
     accountant shall keep confidential all information it receives in the
     course of such inspection and may report the findings of said examination
     of records to Licensor and to Licensee only insofar as it is necessary to
     evidence any mistake or impropriety on the part of Licensee and/or its
     sublicensees.

                      ARTICLE IV - LICENSOR'S OBLIGATIONS

1.   Licensor agrees that it will file and diligently prosecute an application
     to register the Licensed Trademark in the Territory. Licensor, at its
     expense, will maintain such registration in the Territory for so long as
     Licensee shall market Licensed Product bearing the Licensed Trademark in
     the Territory.

     Upon the request of Licensor from time to time, Licensee will execute all
     instruments or papers and render such other assistance as Licensor may
     reasonably request in order to effect the registration and/or the recording
     of Licensee as the registered user of the Licensed Trademark.

2.   In the event the Licensed Trademark is infringed in any country of the
     Territory, Licensor agrees to immediately commence appropriate legal action
     to stop such infringement at its sole expense, and Licensee shall assist it
     to do so, at Licensee's expense. If Licensor fails to initiate such action
     within ninety (90) days after being notified by Licensee of the
     infringement, Licensee shall have the right to bring such action at its own
     expense, in the name of Licensor, and the latter agrees to give Licensee
     its complete cooperation, at Licensor's expense.

                                      -4-


                      ARTICLE V - LICENSEE'S OBLIGATIONS

1.   Licensee agrees that the Licensed Products sold by Licensee bearing the
     Licensed Trademark will be of such a standard of quality so as not to
     jeopardize the Licensed Trademark. The standard of quality shall meet the
     requirements of the appropriate administrative agency in the Territory in
     connection with such Licensed Product. Licensee will periodically forward
     to Licensor, upon Licensor's written request, samples of the Licensed
     Products as may reasonably be required to determine that the above
     standards are being met.

2.   Nothing contained in this Agreement will grant to Licensee any right, title
     or interest in the Licensed Trademark. The Licensed Trademark is the sole
     property of the Licensor and any and all uses by Licensee of the Licensed
     Trademark in the Territory will inure to the benefit of the Licensor.

3.   Licensee will not raise or cause to be raised any questions concerning, or
     objections to, the validity of the Licensed Trademark or to the right of
     the Licensor thereto, on any grounds whatsoever.

                     ARTICLE VI - DURATION AND TERMINATION

1.   Unless sooner terminated as provided herein, this Agreement shall terminate
     at the date upon which Licensee and its sublicensees shall cease to market
     and sell the Licensed Product in the Territory.

2.   If either party hereto shall fail to comply with any of its obligations
     under this Agreement, and shall fail to remedy any such breach within
     ninety (90) days, after receipt of written notice thereof from the other
     party, the party not in default shall have the right to terminate this
     Agreement by giving written notice of termination.

3.   Termination of this Agreement or any license granted hereunder for any
     reason by either party shall not relieve the parties of any obligation
     accruing prior to such termination.

                 ARTICLE VII - REPRESENTATIONS AND WARRANTIES

1.   The Licensor hereby represents and warrants to the Licensee as follows:

     a)   This Agreement has been duly executed and delivered by the Licensor

          Licensor enforceable against the Licensor in accordance with its

                        ARTICLE VIII - INDEMNIFICATION

1.   The Licensor will reimburse, indemnify and hold harmless the Licensee from
     and against (i) breach by the Licensor of its representations, warranties

                     ARTICLE IX - MISCELLANEOUS PROVISIONS

1.   Successors and Assigns - This Agreement shall be binding upon and inure to
     ----------------------
     the benefit of the successors and assigns of the parties hereto. This
     Agreement cannot be assigned by any of the parties hereto without the prior
     approval of the other party in writing; provided, however, that either
     party may, without such consent, assign this Agreement in connection with
     the transfer or sale of all or substantially all of its business or in the
     event of its merger or consolidation with another company. Any purported
     assignment in violation of the preceding sentence shall be void. Any
     permitted assignee shall assume all obligations of its assignor under this
     Agreement. No assignment shall relieve either party of responsibility for
     the performance of any accrued obligation which such party then has
     hereunder.

     Notwithstanding the foregoing, if prior to FDA approval of the initial
     Licensed Product, Licensee (i) sells 60% or more of its tangible assets, or
     (ii) participates in or becomes subject to a merger in which it is not the
     surviving entity, the transaction may proceed without the consent of
     Licensor but, within ninety (90) days after such event, the parties (in the
     case of Licensee, any successor to Licensee) shall meet to review the
     development and commercialization plans for the Licensed Product of the
     successor entity. If the successor to Licensee does not wish to continue
     aggressively the development and commercialization plans for the Licensed
     Products on the same schedule as CEPHALON, it shall, upon request of
     Licensor, sublicense its right under this Agreement (subject to the
     approval of Licensor in accordance with Article II), for a sublicense fee
     of no more than 1.5X Licensee's investment in the development of Licensed
     Products to the date of such sublicensing in addition to any amounts due to
     Licensor hereunder.

2.   Governing Law - This Agreement shall be governed by and construed in
     -------------
     accordance with the laws of France, except that the scope and validity of
     the Licensed Trademarks shall be governed by the laws of the applicable
     jurisdiction.

                                     -7-














3.   Modification or Waiver - No modification or waiver of any of the provisions
     of this Agreement shall be valid unless in writing signed by the parties
     hereto or signed by the party against whom enforcement of such modification
     or waiver is sought.

4.   Notices - Notice hereunder shall be deemed sufficient if given by
     registered air mail, postage prepaid, and addressed to the party to receive
     such notice at the address given above, or at such other address as may
     hereafter be designated by notice in writing.

5.   Force Majeure - Neither party shall be liable to the other party for any
     delay in performance or nonperformance of any of its obligations hereunder
     caused by any act of God, explosion, fire, war, labor disputes, order or
     decree of any court or governmental authority, or other unforeseeable cause
     wholly beyond the control and without the negligence of such party provided
     the party so affected promptly notifies the other party and uses its best
     efforts to remove such cause as soon as reasonably practical.

6.   Counterparts - This Agreement shall become binding when any one or more
     counterparts hereof, individually or taken together, shall bear the
     signatures of Licensor and Licensee. This Agreement may be executed in two
     or more counterparts, each of which shall be deemed an original as against
     any party whose signature appears thereon, but all of which together shall
     constitute one and the same instrument.

7.   Entire Agreement - This Agreement contains all of the covenants, terms and
     undertakings of the parties with respect to the particular subject matter
     hereof and all prior agreements among the parties relating to the subject
     matter hereof, whether written or oral, are merged herein and shall be of
     no force and effect. This Agreement cannot be changed, modified or
     discharged except by an instrument in writing signed by both parties
     hereto.

8.   Severability - If any provision of this Agreement or application thereof to
     anyone or under any circumstances is adjudicated to be invalid or
     unenforceable, such invalidity or unenforceability shall not affect any
     other provisions or applications of this Agreement which can be given
     effect without the invalid or unenforceable provision or application.

                            ARTICLE X - ARBITRATION

Any difference between the parties hereto concerning the interpretation or
application of this Agreement which could not be resolved amicably shall be
finally settled in accordance with

                                      -8-


the Rules of Conciliation and Arbitration of the International Chamber of
Commerce by three arbitrators designated in accordance with said Rules. This
Agreement shall be construed, and the rights of the parties determined, in
accordance with the French laws. Judgment upon the award rendered may be entered
in any court having jurisdiction thereof. The place of arbitration will be
Geneva.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement in duplicate
as of the day and year first written above.
