         4.       Confidentiality and Non-Disclosure Agreement. Consultant
                  acknowledges that the business of OBL includes specifically
                  and primarily the development of new orthopaedic and podiatric
                  devices for use in medical and surgical treatment. At meetings
                  of the Consultant and OBL, there may be disclosed to the
                  Consultant proprietary, secret or confidential information
                  relating to products, techniques or devices that are being
                  developed or contemplated for development by OBL. Consultant
                  further acknowledges that it is the intent of OBL to preserve
                  the secrecy and confidentiality of such confidential
                  information and from time to time to seek patents for the
                  products developed by OBL. Consequently, Consultant agrees
                  that he will not, during or after secret or confidential
                  information, knowledge or data relating to the business
                  affairs or contemplated or developed products of OBL acquired
                  by, disclosed to or

   3
                  otherwise learned by Consultant and will use such information,
                  knowledge or data only for the benefit of OBL, its successors
                  and assigns and not for his own benefit or the benefit of
                  others.

Upon termination of his service as a professional advisor to OBL, for whatever
reason whatsoever, all documents, records, notebooks and other papers and
computer software, if any, containing secret, proprietary or confidential
information of OBL and information relating to new products developed or
contemplated by OBL, including all copies thereof then in Consultant's
possession or control, whether prepared by him or others, will be promptly
delivered to OBL by Consultant, and no copies shall be retained by Consultant.

         It is understood that the following information shall not be regarded
as "confidential": Information already known to Consultant when disclosed to
him, including technical information, processes, techniques or methods already
practiced by Consultant or described in published literature or otherwise in the
public domain.

         OBL acknowledges that from time to time Consultant may, during the
course of his service as a professional advisor, disclose to OBL confidential or
proprietary information owned by or under the control of Consultant. In such
event, prior to the disclosure of any such confidential information, Consultant
shall identify such information as proprietary, secret or confidential, and in
such event, OBL agrees that it will not disclose any such secret, confidential
or proprietary information, knowledge or data to any third party and will not
use such information, knowledge or data in the development of OBL's products
without the prior consent of Consultant. Notwithstanding the foregoing, no
information identified as confidential by Consultant shall be deemed
confidential it at the time of disclosure by Consultant such information was
already known by OBL from other sources, described in published literature or
otherwise in the public domain.

         5.       Professional Ethics and Disclosures. OBL and Consultant agree
                  to make full and complete disclosures of their relationship
                  and to comply in all respects thereto with all applicable laws
                  and the ethical and moral canon, standards and rules of
                  conduct of the medical-profession generally and in particular
                  all surgical, podiatric or other applicable organizations or
                  societies.

         6.       Remedies. Consultant and OBL each acknowledge that compliance
                  with this Agreement and, in particular, with the provisions of
                  Paragraph 4 above, is necessary to protect the proprietary
                  interests of the parties and that a breach thereof will be no
                  adequate remedy at law. In the event of any breach of the
                  covenants contained in this Agreement, the non-breaching
                  party, in addition to any damages that may be awarded, shall
                  be entitled to injunctive and such other relief as may by
                  awarded by a court having competent jurisdiction over the
                  parties. In addition, if Consultant shall in any way breach
                  the covenants and agreements of Paragraph 4 hereof, as an
                  additional remedy to OBL for such breach, Consultant shall
                  forfeit his option to purchase OBL stock, and OBL shall have
                  the right, but not the obligation, to redeem from Consultant
                  all shares of OBL stock purchased by Consultant through prior
                  exercise of his stock option, at consultant's acquisition
                  cost.

         7.       Non-competition. Consultant acknowledges the importance of OBL
                  maintaining strict confidentiality of its proprietary and
                  confidential information, and all plans for product
                  development. Consequently, during the three (3) year term of
                  this Agreement, Consultant agrees that he will not in any
                  capacity, directly or indirectly, consult, work on or
                  otherwise participate in any projects for any third party that
                  relate to the development, modification, evolution, formation
                  or enhancement of any product currently sold or marketed by
                  OBL.

         8.       Indemnity. OBL agrees to indemnify and hold harmless
                  Consultant from any loss, cost or damage, including reasonable
                  attorneys' fees, arising out of any action taken or advice
                  given in good faith by Consultant while performing services
                  for OBL as required herein.

         9.       Independent Contractor. Consultant acknowledges that he is
                  acting as an independent contractor to OBL and that he has no
                  authority express or implied to act for or on behalf of OBL in
                  dealing with any third party.

         10.      Work for Hire. Consultant agrees that all work performed by
                  Consultant for OBL, including but not limited to the
                  development or enhancement of processions, products, concepts
                  or devices relating to orthopaedic or podiatric products,
                  invented, developed, enhanced or produced by OBL shall be
                  considered works made for hire, the ownership and all rights
                  to which shall remain perpetually in OBL.

         11.      Successors and Assigns. This Agreement shall be binding upon
                  the parties hereto and their respective successor and assigns.

                  entire contract between the parties with respect to the
                  subject matter hereof. This Agreement may not be amended or
                  modified except by an instrument in writing signed by the
                  party to be charged.

         13.      No Waiver. No default by Consultant hereunder shall be waived
                  by OBL except in writing and no waiver of any other default or
                  of another occurrence of the same default at a future time.

         14.      Severability. Should any term, provision or clause hereof be
                  held to be invalid or unenforceable, such invalidity or
                  unenforceability shall not affect any other of the provisions
                  or clauses hereof or thereof which can be given effect without
                  such invalid or unenforceable provision, all of which shall
                  remain in full force and effect.


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