                 WHEREAS, the Board of Directors of the Company, at a meeting
held on July 19, 1991, determined that it would be in the best interests of the
Company and its shareholders to retain the services of certain key employees in
order to assure the continuity in the management of the Company's
administration and operations by entering into retention agreements with such
key employees for a period of three (3) years; and

                 WHEREAS, the Employee is a valuable employee of the Company
and an integral part of its management who participates in the decision-making
process relative to short and long term planning and policy for the Company;
and

                 WHEREAS, the Company wishes to assure itself of the continued
services of the Employee for the said period of three (3) years, by granting to
the Employee a Retention Award under certain conditions if he remains employed
by the Company at the end of said period of three (3) years;

                 NOW THEREFORE, it is hereby agreed by and between the parties
hereto as follows:

1.  RETENTION AWARD

         (a)     In the event the Employee's employment is not terminated prior
                 to July 19, 1994 by the Company or any of its subsidiaries or
                 affiliates for a reason specified in paragraph (b) below, and
                 provided further that the Employee remains employed by the
                 Company or any of its subsidiaries or affiliates on July 19,
                 1994, then the Employee shall be eligible to receive a
                 Retention Award of $95,445 on July 19, 1994.  In the event the
                 Employee's employment terminates prior to July 19, 1994
                 because of his death or disability, because of a Change of
                 Control as defined in paragraph (c) below, or because the
                 Employee is terminated by the Company or any of its
                 subsidiaries or affiliates for a reason other than those
                 specified in paragraph (b) below, then a pro-rata share of
                 said Retention Award shall be paid to the Employee or the
                 Employee's beneficiary.  Said pro-rata share of the Retention
                 Award shall be based on the date of termination in relation to
                 the three-year period of July 19, 1991 through July 19, 1994,
                 and shall be paid to the Employee or the Employee's
                 beneficiary as soon as practicable after the Employee's date
                 of termination.

         (b)     No portion of the Retention Award specified in paragraph 
   3

                 (a) above shall be paid to the Employee or the Employee's
                 beneficiary in the event the Employee's employment is
                 terminated by the Company or any of its subsidiaries or its
                 affiliates because of:

                 (i)      the Employee's serious, willful misconduct in respect
                          of the Employee's duties, including conviction for a
                          felony or perpetration of a common law fraud which
                          has resulted, or is likely to result, in material
                          economic damage to the Company or any of its
                          subsidiaries or affiliates; or

                 (ii)     the Employee's repeated failure to follow rules or
                          procedures of the Company or any of its subsidiaries
                          or affiliates, or to meetbona fide objectives and
                          qualifications duly promulgated as part of the
                          customary personnel practices of the Company or any
                          of its subsidiaries or affiliates.

         (c)     As used in this Agreement, "Change in Control" means the
                 happening of any of the following:

                 (i)      the acquisition by any party or parties of the
                          beneficial ownership of 25% or more of the voting
                          shares of the Company, or

                 (ii)     the occurrence of a transaction requiring
                          shareholders approval for the acquisition of the
                          Company through purchase or exchange of stock or
                          assets, or by merger, or otherwise, or

                (iii)     the election during a period of 24 months, or less,
                          of 30% or more, of the members of the Board of
                          Directors of the Company, without the approval of a
                          majority of the Board of Directors as constituted at
                          the beginning of the period, or

                 (iv)     the occurrence of a transaction requiring the filing
                          of a report or disclosure with the Securities and
                          Exchange Commission in connection with the obtaining
                          of an interest in the Company through a purchase or
                          exchange of stock or assets, or by merger or
                          otherwise.

         segregation of assets to assure payment of such Retention Award.

 3.      Litigation Expenses; Arbitration

         (a)     In the event of any litigation or other proceeding between the
                 Company or any of its subsidiaries or affiliates and the

                 such litigation or other proceeding, including his reasonable
                 attorneys' fees and expenses, provided that such litigation or
                 proceeding results in any:

                 (i)      settlement requiring the Company or any of its
                          subsidiaries or affiliates to make a payment to the

                 survive the termination for any reason of this Agreement
                 (whether such termination is by the Company or any of its
                 subsidiaries or affiliates, by the Employee, upon the
                 expiration of this Agreement or otherwise).

         (b)     In the event of any dispute or difference between the Company
                 or any of its subsidiaries or affiliates and the Employee with
                 respect to the subject matter of this Agreement and the
                 enforcement of rights hereunder, the Employee may, in his sole
                 discretion by notice to the Company or any such subsidiary or
                 affiliate, require such dispute or difference to be submitted
                 to arbitration.  The arbitrator or arbitrators shall be
                 selected by agreement of the parties or, if they cannot agree
                 on an arbitrator or arbitrators within 30 days after the
                 Employee had notified the Company or any of its subsidiaries
                 or affiliates of his desire to have the question settled by
                 arbitration, then the arbitrator or arbitrators shall be
                 selected by the American Arbitration Association (the "AAA")
                 in Philadelphia, Pennsylvania, upon the application of the
                 Employee.  The determination reached in such arbitration shall
                 be final and binding on both parties without any right of
                 appeal or further dispute.  Execution of the determination by
                 such arbitrator or arbitrators may be sought in any court of
                 competent jurisdiction.  The arbitrators shall not be bound by
                 judicial formalities and may abstain from following the strict
                 rule of evidence and shall interpret this Agreement as an
                 honorable engagement and not merely as a legal obligation.
                 Unless otherwise agreed by the parties, any such arbitration
                 shall take place in Wilmington, Delaware, and shall be
                 conducted in accordance with the rules of the AAA.

         regulation or ruling.

         or any of its subsidiaries or affiliates and the Employee with respect
         to the subject matter hereof.

         or unenforceability shall not affect any other provision or part of a

         provision or part of a provision shall to the full extent consistent
         with law continue in full force and effect.  If this Agreement is held
