5.       Benefits and Expenses.

         A)       Company Plan Participation. Employee and his dependants shall
                  be entitled to receive those employee benefits (including
                  without limitation medical plan, dental plan, optional 401K
                  participation and expense reimbursement) as shall be provided
                  to similarly situated executive employees of the Company
                  ("Benefits").

         B)       Vacation. Employee will be entitled to three weeks vacation
                  with the ability to carry over any unused vacation earned in a
                  given year to the following year.

         C)       Tax Gross-Up. In the event any amount or benefit payable to
                  the Employee under this Agreement or under any other plan,
                  agreement or arrangement applicable to the Employee, is
                  subject to an excise tax imposed under Section 4999 of the
                  Internal Revenue Code of 1986, as amended (the "Code") (or
                  imposed under any successor provision of the Code imposing a
                  tax liability on "excess parachute payments" as that term is
                  defined in Code Section 280G), Employee shall be entitled, in
                  addition to any other amounts payable under the terms of this
                  Agreement or under any other plan, agreement or arrangement
                  applicable to the Employee, to a cash payment in an amount
                  sufficient to indemnify the Employee (or such other person as
                  may be liable for the payment of such excise tax) for the
                  amount of any such excise tax, and leaving Grantee with an
                  amount, net after all federal, state and local taxes, equal to
                  the amount Grantee would have had if no portion of his benefit
                  under the Plan constituted an "excess parachute payment.
                  Notwithstanding the foregoing, the determination of the amount
                  necessary to indemnify the Employee shall be made taking into
                  account all other payments made to the Employee under any
                  plans, agreements or arrangements aside from this Agreement
                  that are intended to indemnify the Employee with respect to
                  excise taxes on "excess parachute payments. Any disputes as to
                  calculations to be made under this paragraph shall be resolved
                  by the Company's independent auditors, whose determinations
                  shall be final and binding.







6.       Confidentiality. Employee recognizes and acknowledges that the
         Proprietary Information (as hereinafter defined) is a valuable, special
         and unique asset of the Business of the Company. As a result, both
         during the Term and thereafter, Employee shall not, without the prior
         written consent of the Company, for any reason either directly or
         indirectly divulge to any third-party or use for his own benefit, or
         for any purpose other than the exclusive benefit of the Company, any
         confidential, proprietary, business and technical information or trade
         secrets of the Company or of any subsidiary or affiliate of the Company
         ("Proprietary Information") revealed, obtained or developed in the
         course of his employment with the Company. Such Proprietary Information
         shall include, but shall not be limited to, the intangible personal
         property described in Section 7(b) hereof, any information relating to
         methods of production and manufacture, research, computer codes or
         instructions (including source and object code listings, program logic
         algorithms, subroutines, modules or other subparts of computer programs
         and related documentation, including program notation), computer
         processing systems and techniques, concepts, layouts, flowcharts,
         specifications, know-how, any associated user or service manuals or
         other like textual materials (including any other data and materials
         used in performing the Employee's duties), all computer inputs and
         outputs (regardless of the media on which stored or located), hardware
         and software configurations, designs, architecture, interfaces, plans,
         sketches, blueprints, and any other materials prepared by the Employee
         in the course of, relating to or arising out of his employment by the
         Company, or prepared by any other Company employee, representative, or
         contractor for the Company, or its customers, costs, business studies,
         business procedures, finances, marketing data, methods, plans and
         efforts, the identities of licensees, strategic partners, customers,
         contractors and suppliers and prospective licensees, strategic
         partners, customers, contractors and suppliers, the terms of contracts
         and agreements with licensees, strategic partners, customers,
         contractors and suppliers, the Company's relationship with actual and
         prospective licensees, strategic partners, customers, contractors and
         suppliers and the needs and requirements of, and the Company's course
         of dealing with, any such actual or prospective licensees, strategic
         partners, customers, contractors and suppliers, personnel information,
         customer and vendor credit information, and any other materials that
         have not been made available to the general public, provided, that
         nothing herein contained shall restrict Employee's ability to make such
         disclosures during the course of his employment as may be necessary or
         appropriate to the effective and efficient discharge of the duties
         required by or appropriate for his Position or as such disclosures may
         be required by law; and further provided, that nothing herein contained
         shall restrict Employee from divulging or using for his own benefit or
         for any other purpose any Proprietary Information that is readily
         available to the general public so long as such information did not
         become available to the general public as a direct or indirect result
         of Employee's breach of this Section 6. Failure by the Company to mark
         any of the Proprietary Information as confidential or proprietary shall
         not affect its status as Proprietary Information under the terms of
         this Agreement.


7.       Property.






         A)       Ownership. All right, title and interest in and to Proprietary

                  shall not make, retain, remove and/or distribute any copies of
                  any of the foregoing for any reason whatsoever except as may
                  be necessary in the discharge of his assigned duties and shall
                  not divulge to any third person the nature of and/or contents

                  necessary in the performance of his duties; and upon the
                  termination of his employment with the Company, he shall leave
                  with or return to the Company all originals and copies of the
                  foregoing then in his possession, whether prepared by Employee
                  or by others.

                           patents, trademarks and trade names, or similar
                           intangible personal property which have been or are
                           developed or created in whole or in part by Employee
                           (1) at any time and at any place while the Employee
                           is employed by Company and which, in the case of any
                           or all of the foregoing, are related to and used in
                           connection with the Business of the Company, (2) as a
                           result of tasks assigned to Employee by the Company,
                           or (3) from the use of premises or personal property
                           (whether tangible or intangible) owned, leased or
                           contracted for by the Company (collectively, the
                           "Intellectual Property"), shall be and remain forever
                           the sole and exclusive property of the Company. The
                           Employee shall promptly disclose to the Company all
                           Intellectual Property, and the Employee shall have no
                           claim for additional compensation for the
                           Intellectual Property.






                  (ii)     The Employee acknowledges that all the Intellectual
                           Property that is copyrightable shall be considered a
                           work made for hire under United States Copyright Law.
                           To the extent that any copyrightable Intellectual
                           Property may not be considered a work made for hire
                           under the applicable provisions of the United States
                           Copyright Law, or to the extent that, notwithstanding
                           the foregoing provisions, the Employee may retain an
                           interest in any Intellectual Property that is not
                           copyrightable, the Employee hereby irrevocably
                           assigns and transfers to the Company any and all
                           right, title, or interest that the Employee may have
                           in the Intellectual Property under copyright, patent,
                           trade secret and trademark law, in perpetuity or for
                           the longest period otherwise permitted by law,
                           without the necessity of further consideration. The
                           Company shall be entitled to obtain and hold in its
                           own name all copyrights, patents, trade secrets, and
                           trademarks with respect thereto.

                  (iii)    Employee further agrees to reveal promptly all
                           information relating to the same to an appropriate
                           officer of the Company and to cooperate with the
                           Company and execute such documents as may be
                           necessary or appropriate (1) in the event that the
                           Company desires to seek copyright, patent or
                           trademark protection, or other analogous protection,
                           thereafter relating to the Intellectual Property, and
                           when such protection is obtained, to renew and
                           restore the same, or (2) to defend any opposition
                           proceedings in respect of obtaining and maintaining
                           such copyright, patent or trademark protection, or
                           other analogous protection.

                  (iv)     In the event the Company is unable after reasonable
                           effort to secure Employee's signature on any of the
                           documents referenced in Section 7.1(iii) hereof,
                           whether because of Employee's physical or mental
                           incapacity or for any other reason whatsoever,
                           Employee hereby irrevocably designates and appoints
                           the Company and its duly authorized officers and
                           agents as Employee's agent and attorney-in-fact, to
                           act for and in his behalf and stead to execute and
                           file any such documents and to do all other lawfully
                           permitted acts to further the prosecution and
                           issuance of any such copyright, patent or trademark
                           protection, or other analogous protection, with the
                           same legal force and effect as if executed by
                           Employee.

                  written notice of the termination of his employment hereunder

                  timely manner base salary or any other material form of

                  terminate as of the date of termination, except that Employee
                  shall be entitled to the accrued and unpaid base salary,
                  employee benefits (including expense reimbursement) as
                  provided herein ("Benefits") and other forms of compensation
                  and bonus payable herein ("Other Compensation") up through the
                  date of termination. In addition, solely if such termination

                  standard form termination letter as provided for in Section 10
                  below, Employee shall be entitled to receive (i) severance in
                  an amount equal to the Employee's base salary, and (ii)
                  medical and dental coverage on terms and conditions comparable

                  this Agreement, both for the period of twelve (12) months
                  commencing upon the date of such termination. Except as
                  specifically set forth in this Section 9.1, all base salary,
                  Benefits and Other Compensation shall cease at the time of
                  such termination, subject to the terms of any benefit or
                  compensation plan then in force and applicable to Employee.
                  Except as specifically set forth in this Section 9.1, the
                  Company shall have no liability or obligation to Employee or
                  any other person claiming under or through him by reason of
                  such termination.

         9.2      Termination for Cause. If Company terminates Employee's
                  employment for Cause, then this Agreement shall terminate

                  hereunder shall terminate as of the date of termination,
                  except that Employee shall be entitled to the accrued and
                  unpaid portion of his base salary, Benefits and Other
                  Compensation up through the date of termination. For purposes
                  of this Agreement, the term "Cause" shall mean (i) any
                  material breach of Employee's employment obligations, which
                  breach remains uncured seven (7) days after written notice of
                  such breach from the Company, or (ii) Employee commits an act
                  or omission which results in or is intended to result in gain
                  or personal enrichment of Employee at the expense of Company;
                  or (iii) an act by Employee involving any type of willful
                  misconduct with respect to the Company, including without

                  the course of his employment; or (iv) during the term of
                  Employee's employment, Employee's conviction of a felony.
                  Except as specifically set forth in this Section 9.2, the
                  Company shall have no liability or obligation to Employee or
                  any other person claiming under or through him by reason of
                  such termination.

                  shall terminate immediately and Employee's rights to
                  compensation and benefits hereunder shall terminate as of the
                  date of death, except that Employee's executors, legal

                  assigns or any other person claiming under or through him by
                  reason of Employee's death, except that Employee's executors,
                  legal representatives, administrators, or beneficiaries will
                  be entitled to receive the payment prescribed under any life,
                  death or disability benefits plan in which he is a participant
                  as an employee of the Company, and to exercise any rights

                  under any disability insurance plan or arrangement in which

                           on the date hereof or a sale of substantially all of
                           the assets of the Company. For these
                           purposes,"Person" means an individual, partnership,
                           corporation, joint venture, association, trust,
                           unincorporated association, other entity or
                           association.


10.      Termination Letter. As a condition precedent to the Company's payment
         of severance and continuation of medical and dental insurance coverage
         pursuant to Sections 9.1, 9.5, 9.6 and 9.7 above, Employee must sign
         and deliver to Company termination letter, without revocation, which
         includes a broad-based employment release (containing, without
         limitation, a release of claims for age discrimination), an obligation
         to return Company property and a reiteration of Employee's
         confidentiality obligations, within the time frame specified in the
         termination letter.


11.      Company Understanding. The Company does not want to benefit from any
         proprietary or other information, in any form, that Employee is under a
         duty not to use or divulge, whether it be from Employee's current
         employer or any other person or entity. Accordingly and as a condition
         of employment hereunder, Employee is instructed not to violate the
         terms of any such restriction or otherwise breach said duty. In
         furtherance thereof, and without limiting other action, Employee
         represents and warrants to the Company that:






         A        There are no restrictions, agreements or understandings
                  whatsoever to which Employee is a party which would prevent or
                  make unlawful Employee's execution of this Agreement or
                  Employee's employment hereunder, or which are or would be
                  inconsistent or in conflict with this Agreement or Employee's
                  employment hereunder, or would prevent, limit or impair in any
                  way the performance by Employee of his obligations hereunder,

         B        Employee's execution of this Agreement and Employee's
                  employment hereunder shall not constitute a breach of any
                  contract, agreement or understanding, oral or written, to
                  which Employee is a party or by which Employee is bound, and

         C        Employee is free to execute this Agreement and to enter into
                  the employ of the Company pursuant to the provisions set forth
                  herein.


12.      Survival of Provisions. Notwithstanding anything in this Agreement to
         the contrary, all representations, warranties, obligations of
         performance, statements, responsibilities, indemnities, terms or
         conditions impliedly or expressly involving performance subsequent to
         the expiration or termination of this Agreement, or which cannot be
         determined to have been fully performed until after such time, or which
         by a fair reading of their nature are intended to survive shall be
         deemed to survive. If for any reason Employee shall continue to be
         employed by the Company following the termination of Employee's
         employment under this Agreement, Employee shall have no right to
         receive any severance or other payments hereunder until Employee ceases
         to be employed by the Company, whereupon Employee's right to severance
         or other payments, if any, shall be governed by the provisions of
         Section 9 hereof with respect to the particular circumstances involved
         in the Employee's termination of employment.


13.      Successors and Assigns. This Agreement shall inure to the benefit of
         and be binding upon the Company and Employee and their respective
         successors, executors, administrators, heirs and/or permitted assigns;
         provided, however, that neither Employee nor the Company may make any
         assignments of this Agreement or any interest herein, by operation of
         law or otherwise, without the prior written consent of the other
         parties hereto.


14.      Employee Benefits. This Agreement shall not be construed to be in lieu
         or to the exclusion of any other rights, benefits and privileges to
         which Employee may be entitled as an employee of the Company under any
         retirement, pension, profit-sharing, insurance, hospital or other plans
         or benefits which may now be in effect or which may hereafter be
         adopted.

         Agreement shall be made in writing and sent by certified or registered
         mail, return receipt requested, by hand delivery, or by recognized

         by an Agreement in writing signed by each of the parties hereto.


17.      Waiver. The waiver of the breach of any term or provision of this
         Agreement shall not operate as or be construed to be a waiver of any
         other or subsequent breach of this Agreement.


18.      Governing Law. This Agreement shall be construed and enforced in
         accordance with the laws of the Commonwealth of Pennsylvania.







19.      Invalidity. In case any one or more of the provisions contained in this
         Agreement shall, for any reason, be held to be invalid, illegal or
         unenforceable in any respect, such invalidity, illegality or
         unenforceability shall not affect the validity of any other provision
         of this Agreement, and such provision(s) shall be deemed modified to
         the extent necessary to make it enforceable.


20.      Section Headings. The section headings in this Agreement are for
         convenience only; they form no part of this Agreement and shall not
         affect its interpretation.


21.      Number of Days. In computing the number of days for purposes of this
         Agreement, all days shall be counted, including Saturdays, Sundays and
         legal holidays; provided, however, that if the final day of any time
         period falls on a Saturday, Sunday or day which is a holiday in the

22.      Specific Enforcement; Extension of Period.

         A)       Employee acknowledges that the restrictions contained in
                  Sections 6, 7, and 8 hereof are reasonable and necessary to
                  protect the legitimate interests of the Company and its
                  affiliates and that the Company would not have entered into
                  this Agreement in the absence of such restrictions. Employee
                  also acknowledges that any breach by him of Sections 6, 7, and
                  8 hereof will cause continuing and irreparable injury to the
                  Company for which monetary damages would not be an adequate
                  remedy. The Employee shall not, in any action or proceeding to
                  enforce any of the provisions of this Agreement, assert the
                  claim or defense that an adequate remedy at law exists. In the
                  event of such breach by Employee, the Company shall have the
                  right to enforce the provisions of Sections 6, 7, and 8 of
                  this Agreement by seeking injunctive or other relief in any
                  court, and this Agreement shall not in any way limit remedies
                  of law or in equity otherwise available to the Company. If an
                  action at law or in equity is necessary to enforce or
                  interpret the terms of this Agreement, the prevailing party
                  shall be entitled to recover, in addition to any other relief,
                  reasonable attorneys' fees, costs and disbursements. In the
                  event that the provisions of Sections 6, 7, and 8 hereof
                  should ever be adjudicated to exceed the time, geographic, or
                  other limitations permitted by applicable law in any
                  applicable jurisdiction, then such provisions shall be deemed
                  reformed in such jurisdiction to the maximum time, geographic,
                  or other limitations permitted by applicable law.

         B)       In the event that Employee shall be in breach of any of the
                  restrictions contained in Section 8 hereof, then the
                  Restricted Period shall be extended for a period of time equal
                  to the period of time that Employee is in breach of such
                  restriction.








23.      Consent to Suit. Any legal proceeding arising out of or relating to
         this Agreement shall be instituted in the District Court of the Eastern
         District of Pennsylvania, or if such court does not have jurisdiction
         or will not accept jurisdiction, in any court of general jurisdiction
         in the Commonwealth of Pennsylvania, and the Employee hereby consents
         to the personal and exclusive jurisdiction of such court and hereby
         waives any objection that the Employee may have to the laying of venue
         of any such proceeding and any claim or defense of inconvenient forum.


24.      Counterparts. This Agreement may be executed in one or more
         counterparts, each of which shall be deemed an original, and all of
         which together shall be deemed to be one and the same instrument.


                  IN WITNESS WHEREOF, the parties have caused this Agreement to
be executed the day and year first written above.
