ordinary course of performing the Consultant's duties. Consultant

 
agrees that he will not at any time, whether during or after the termination of 
his status as a Consultant to IBAH, reveal to any person or entity any trade 
secrets or confidential information of IBAH.

Consultant understands that client companies disclose confidential information
to IBAH and that IBAH agrees, in writing, to maintain the confidentiality of 
this information. Accordingly, Consultant agrees that he will not at any time, 
whether during or after the termination of his status as a Consultant to IBAH, 
reveal to any person or entity any trade secrets or confidential information 
concerning any third party or client to which IBAH owes a confidentiality 
obligation.

     6.1  Confidential information does not include disclosed information that:
          (a) is or becomes part of the public domain through no fault of
          Consultant; (b) is disclosed to Consultant by a third party entitled
          to disclose it; or (c) is required by law to be disclosed.

     6.2  Consultant will only use the confidential information furnished by
          IBAH for the purpose of fulfilling his obligations under this
          Agreement. Upon the completion or earlier termination of this
          Agreement and at IBAH's request, Consultant will promptly return all
          written confidential information.

     6.3  Consultant will not use any such confidential information for his own
          benefit or for the benefit of any third party, and will not furnish to
          any third party any materials which incorporate any confidential
          information except as otherwise hereinabove provided. All obligations
          of confidentiality and non-disclosure set forth in this Agreement will
          survive, without limitation, the expiration or earlier termination of
          this Agreement.

     6.4  The obligations of confidentiality contained herein shall remain in 
          effect for five (5) years after the termination of this Agreement.

7.0  INTELLECTUAL PROPERTY
     ---------------------

If at any time or times during the term of this Agreement, Consultant shall 
(either alone or with others), make, conceive, create, discover, invent or 
reduce to practice any invention, modification, discovery, design, development, 
improvement, process, software program, work of authorship, documentation, 
formula, data, whether or not patentable or registrable under copyright, 
trademark or similar statutes (including but not limited to the Semiconductor 
Chip Protection Act) or subject to analogous protection (herein called 
"Developments") that:

          (a) relates to the business of IBAH or any client of or supplier of
          IBAH or any of the products or services being developed, manufactured
          or sold by IBAH or which may be used in relation therewith;

          (b) results from tasks assigned by IBAH; or,

 
          (c) results from the use of premises or personal property (whether 
          tangible or intangible) owned, leased or contracted for by IBAH,

such Developments and the benefits thereof are and shall immediately become the 
sole and absolute property of IBAH and its assigns, as "work made for hire" or 
otherwise, and Consultant shall promptly disclose to IBAH (or any persons 
designated by it) each such Development and, as may be necessary to ensure 
IBAH's ownership of such Developments. Consultant hereby assigns any rights 
(including, but not limited to, any copyrights and trademarks) Consultant may 
have or acquire in the Developments and benefits and/or rights resulting 
therefrom to IBAH and its assigns without further compensation and shall 
communicate, without cost or delay, and without disclosing to others the same, 
all available information relating thereto (with all necessary plans and models)
to IBAH.

Consultant will, during the term of this Agreement and at any time thereafter, 
at the request and cost of IBAH, promptly sign, execute, make and do all such 
deeds, documents, acts and things as IBAH and its duly authorized agents may 
reasonably require:

     (a)  to apply for, obtain, register and vest in the name of IBAH alone
     (unless IBAH otherwise directs) letters patent, copyrights, trademarks or
     other analogous protection in any country throughout the world and when so
     obtained or vested to renew and restore the same; and

     (b)  to defend any judicial, opposition or other proceedings in respect of
     such applications and any judicial, opposition or other proceedings or
     petitions or applications for revocation of such letters patent, copyright,
     trademark or other analogous protection.

In the event that IBAH is unable, after reasonable effort, to secure 
Consultant's signature on any application for letters patent, copyright or 
trademark registration or other documents regarding any legal protection 
relating to a Development, whether because of Consultant's physical or mental 
incapacity or for any other reason whatsoever, Consultant hereby irrevocably 
designates and appoints IBAH and its duly authorized officers and agents as 
Consultant's agent and attorney-in-fact, to act for and in Consultant's behalf 
and stead to execute and file any such application or applications or other 
documents and to do all other lawfully permitted acts to further the prosecution
and issuance of letters patent, copyright or trademark registrations or any 
other legal protection thereon with the same legal force and effect as if 
executed by Consultant.

     -------------------------------

Modifications to this Agreement may only be made with the written agreement of 
both parties.

 
9.0  CONSULTANT'S RELATIONSHIP WITH IBAH 
     -----------------------------------

Consultant's relationship with IBAH under this Agreement shall be that of an 
independent contractor, and nothing in the Agreement or the arrangement for 
which it is made shall constitute Consultant, or anyone furnished or used by 
Consultant in the performance of the services contemplated by this Agreement, as
an employee, joint venture partner or servant of IBAH.

Consultant will not participate in IBAH employee benefit plans nor receive any 
other compensation beyond that stated above. Consultant will not have power or 
authority to bind IBAH or to assume or create any obligation or responsibility, 
express or implied, on IBAH's part or in IBAH's name except as otherwise set 
forth in this Agreement and Consultant will not represent to any person or 
entity that Consultant has such power or authority.

10.0 INSURANCE
     ---------

Consultant understands that, since Consultant is an independent contractor, any 
personal injury or property damage suffered by Consultant in the course of 
carrying out any duties under this Agreement will be Consultant's sole 
responsibility. No insurance shall be obtained by IBAH concerning Consultant.

11.0 DEBARMENT
     ---------

Consultant represents that he has never been (i) debarred or convicted of a 
crime for which a person can be debarred under 21 U.S.C. (S) 335a ((S) "335a") 
or any other applicable law nor (ii) threatened to be debarred or indicted for a
crime or otherwise engaged in conduct for which a person can be debarred under 
(S) 335a. Consultant will promptly notify IBAH in the event of any such 
debarment, conviction, threat or indictment occurring during the term of this 
Agreement.

     12.1  In consideration for entering into this Agreement, consideration
           which Consultant hereby acknowledges, Consultant does hereby release
           and forever discharge IBAH and its present and former subsidiaries,
           affiliates, divisions, officers, directors, partners, principals,
           employees, agents, predecessors, assigns, servants, attorneys and
           insurers and each of them, and their respective successors, assigns,
           heirs, administrators and personal representatives of and from all
           actions and causes of action, suits, claims, debts and demands
           whatsoever in law or equity, which Consultant may have or claim to
           have against IBAH as a result of his employment or separation from
           employment, and does hereby covenant not to file a lawsuit to assert
           such claims. Consultant is not being asked to, and does not release,
           any claim which is nonwaivable as a matter of law.

 
     12.2  By this release, Consultant knowingly and voluntarily waives any
           rights under any and all laws which provide legal restrictions on
           IBAH's right to terminate the Employment Agreement and/or the
           Employment relationship with Consultant, and under any federal,
           state, or other governmental statute, regulation, or ordinance,

           of 1964 and 1991; (2) the Age Discrimination in Employment Act of
           1967; and (3) Pennsylvania Human Relations Act. Consultant also
           waives any claim against IBAH for personal injury or any other action
           against IBAH before any body (except for compensable injuries under
           the Pennsylvania Workers Compensation Act). Consultant is not waiving
           any rights or claims that may arise after the date this waiver is
           executed.

     12.3  Consultant forever waives and relinquishes all right to assert any 
           claim for recall, reemployment, or tenure with IBAH.

13.0 COVENANT NOT TO COMPETE
     -----------------------

Not to Compete) shall be made a part of and be incorporated into this Agreement.

14.0 WAIVER
     ------

The failure of either party to enforce any provision of this Agreement shall not
be construed as a waiver or limitation of that party's right to subsequently 
enforce and compel strict compliance with every provision of this Agreement.
