Item 2.  Acquisition or Disposition of Assets


         On August 20, 1998, pursuant to an Investment Agreement, dated August
6, 1998 between Vision-Sciences, Inc., (the "Company") and 3DV Systems, Ltd., a
privately-held Israeli company ("3DV"), (the "Agreement") the Company purchased
338,099 shares of common stock of 3DV (the "Shares"), for a purchase price of $3
million in cash, $500,000 of which the Company had previously advanced to 3DV in
May 1998. The Company funded the purchase price from proceeds received from
Asahi Optical Co., Ltd., (Asahi Kogaku Kogyo Kabushiki Kaisha), a Japanese
corporation ("Asahi"), in exchange for 2,000,000 shares of the Company's common
stock, $.01 par value per share (the "Common Stock"), and certain rights
pursuant to the License Agreement between the Company and Asahi described below.
The Shares were previously unissued shares of common stock of 3DV and, after the
closing of the transaction, represent 25% of the fully diluted share capital of
3DV. Prior to the investment by the Company, 3DV was a subsidiary of RDC
Rafael Development Corporation Ltd. ("RDC"), an Israeli company.

         Pursuant to the Agreement, the Company also issued 500,000 shares of
its Common Stock to RDC in exchange for certain rights. These rights include an
option to purchase all of the remaining shares of capital stock of 3DV owned by
RDC, which represent 62.85% of the fully-diluted share capital of 3DV, at the
then fair market value of such shares.

         In addition, RDC has the right to require the Company to purchase up to
the remaining 75% of the fully-diluted share capital of 3DV, including 12.15%
that would be owned by employees of 3DV, at the then fair market value of such
shares. Two of the Company's directors, Mr. Katsumi Oneda and Mr. Lewis C. Pell,
have been appointed to the Board of Directors of 3DV.

         The terms of the Agreement were determined on the basis of arms'-length
negotiations. Prior to the execution of the Agreement, neither the Company nor
any of its affiliates had any material relationship with either 3DV or RDC.

         In connection with these transactions with 3DV and RDC, the Company
also entered into a License and Manufacturing Agreement (the "L&M Agreement")
with 3DV, dated August 6, 1998, pursuant to which the Company obtained
exclusive, worldwide, perpetual and royalty-free rights to commercially exploit
products in certain fields of use that incorporate, or use, component parts
embodying technology developed by 3DV. The L&M Agreement allows the Company to
sublicense certain of these rights to approved assigns. Asahi, which
manufactures and markets a wide variety of cameras, medical endoscopes and
industrial imaging systems worldwide under the brand name Pentax, is the sole
approved assign under the L&M Agreement, and the Company has sublicensed certain
of its rights under the L&M Agreement to Asahi pursuant to the License Agreement
described below.

         On August 6, 1998, the Company executed a Memorandum of 
Understanding (the "MOU") with Imagineering, Ltd., pursuant to which the 
Company will acquire exclusive rights to research to be performed in 
association with certain innovations as described in the MOU (the 
"Innovations") that are designed to improve the performance of CMOS-based 
Image Sensors. The MOU grants the Company exclusive rights to any resulting 
patent applications and patent rights that result from such research. A 
consultant to Imagineering, Ltd. will perform the research, and the Company 
plans to grant the consultant a nonstatutory stock option for 1,000,000 
shares of the Company's Common Stock, which will vest 100% upon the delivery 
of the Innovations. In addition, the Company will fund the cost of the 
research by Imagineering, Ltd., initially for a period of one year. The terms 
of the MOU were determined on the basis of arms'-length negotiations. Prior 
to the execution of the MOU, neither the Company nor any of its affiliates 
had any material relationship with Imagineering, Ltd. or the consultant.

         The Company also executed a License Agreement (the "License") with
Asahi, dated August 6, 1998, pursuant to which the Company granted Asahi
exclusive rights, as an approved assign under the L&M Agreement, to certain
technology in certain fields and to acquire from the Company and 3DV certain
products having application in those fields. Notwithstanding the License, the
Company has reserved the right to use the technology licensed to Asahi in
products bearing the Company's own trademarks within certain fields of use. In
addition, the License grants Asahi a worldwide, perpetual, royalty-free license
to patentable and non-patentable technology relating to the utilization or
application of CMOS-based Image Sensors, as researched or developed by the
Company, pursuant to the MOU with Imagineering, Ltd. On August 17, 1998, Asahi
paid the Company $5 million in cash in exchange for the rights described above
in the License Agreement and the issuance by the Company to Asahi of 2,000,000
shares of Common Stock. The terms of the License Agreement were determined on
the basis of arms'-length negotiations. Prior to the execution of the License
Agreement, neither the Company nor any of its affiliates had any material
relationship with Asahi.

         3DV Systems Ltd. was established in 1996, and has developed a new
concept of a three-dimensional (3D) video camera, based on unique technology.
The acquisition and manipulation of three-dimensional images provides solutions
for needs that include: medical imaging applications; concept and feasibility
studies; broadcast studio applications; architectural applications; courtroom
visualization; animation and virtual reality; and a wide range of CAD and CAE
services. The 3DV video camera captures a frame or movie in three-dimensional
mode, with each pixel having the Z (depth or distance from the viewer)
dimension. The camera allows the building of a 3D image and its manipulation at
a high frame rate. It is an all-in-one unit (video = color + depth), requiring
significantly less CPU power than other 3D systems, and its design makes it
simple to carry and operate.

         Rafael Development Corporation (RDC) is a business development company
owned by Rafael, a division of the Israeli Ministry of Defense, and an
investment company controlled by Discount Investment Corporation, PEC Israel
Economic Corporation and Elron Electronic Industries (Nasdaq: ELRNF). RDC's
mission is to apply Rafael's proven technologies,

required to sell the RDC Shares based on a valuation of 3DV less than (US) [**].
In the event that the parties shall be unable to reach a consensus on the
valuation of 3DV, the matter shall be submitted to an internationally recognized
investment bank operating in Israel for determination of the fair market value
of the business of 3DV by such investment bank. The purchase price payable for

and, at the election of VSI, a portion of the purchase price (as shall be agreed
between VSI and the Shareholders) shall be paid in common stock of VSI with a
value (based on the average 45 day prior trading value of such common stock)
equal to such portion of the purchase price.
 If RDC requests, VSI will acquire shares of capital stock of 3DV held by
employees of 3DV on the same terms and conditions that VSI shall acquire the RDC
Shares. VSI's right to require RDC to sell the RDC Shares and RDC's right to
require VSI to purchase the RDC Shares is referred to herein as the "Put/Call

                  (b) The Put/Call Right may be exercised by either VSI or RDC
at any time during the Option Period , by delivering a written notice (an
"Exercise Notice") of such Party's desire to exercise the Put/Call Right and
initiate the procedures described on Schedule 3.1.

         3.2 Purchase Price for RDC Shares. The purchase price for the RDC
Shares (the "Put/Call Price") determined pursuant to Section 3.1 shall be

on the Second Closing Date in the manner provided in Section 3.4 below.

         3.3 The Second Closing. The closing of the transactions contemplated by

hold VSI harmless from, any and all Loss based upon, arising out of or resulting
from (i) any breach by 3DV and RDC of any of the representations and warranties

agreements of either of them contained in this Agreement. Any claim by VSI for
indemnification under this Section 8.1 shall be hereinafter referred to as a
"VSI Indemnifiable Claim." Notwithstanding the foregoing, VSI shall not be
entitled to maintain any claim for indemnification under this Section 8.1 unless
and until the aggregate amount of such

                                       23


<PAGE>



Claims exceeds $250,000, and neither 3DV nor RDC shall have any liability under
this Section 8.1 for an amount in the aggregate greater than the Purchase Price
plus the market value of the VSI Shares on the Closing Date.

         8.2 VSI Indemnification of 3DV. (a) On the terms and subject to the
conditions of this Agreement, following the Closing, VSI shall indemnify 3DV
against, and hold 3DV harmless from, any and all Loss based upon, arising out of
or resulting from (i) any breach by VSI of any of the representations and
warranties made by VSI in Section 6 above, or (ii) any breach by VSI of any of
the covenants and agreements of VSI contained in this Agreement. Any claim by
3DV for indemnification under this Section 7.2 shall be hereinafter referred to
as a "3DV Indemnifiable Claim."

 Notwithstanding the foregoing, 3DV shall not be entitled to maintain any claim
for indemnification under this Section 8.2 unless and until the aggregate
amount of such Claims exceeds $250,000, and VSI shall have no liability under
this Section 8.3 for an amount in the aggregate greater than the Purchase Price.

         8.3 Indemnification Procedures. (a) Any party seeking indemnification
hereunder (the "Indemnitee") shall notify the party liable for such
indemnification (the "Indemnitor") in writing of any event, omission or
occurrence which the Indemnitee has determined has given or could give rise to
liabilities or losses that are indemnifiable hereunder (such written notice
being hereinafter referred to as a "Notice of Claim"). Such notice shall be
given promptly after the Indemnitee becomes aware of its own claim or that of a
third party; provided that, the failure of any Indemnitee to give notice (other
than in respect of a third party claim) shall not relieve the Indemnitor of its
obligations under this Section 8 unless such failure continues beyond the time
limits set out in Section 8.5 below which shall relieve the Indemnitor of its
obligations under this Section 8. A Notice of Claim shall specify in reasonable
detail the nature and any particulars of the event, omission or occurrence
giving rise to a right of indemnification. The Indemnitor shall satisfy its
obligations hereunder within thirty (30) calendar days of its receipt of a
Notice of Claim or, if later, within thirty (30) calendar days after the
Indemnitee shall have actually incurred or suffered a liability or loss which is
the subject of such Notice of Claim; provided, however, that so long as the
Indemnitor is in good faith defending a claim pursuant to paragraph (ii) below
and provided that the Indemnitee has not otherwise actually incurred or suffered
a liability or loss for which the Indemnitee was required to pay or otherwise
post a bond, its obligation to indemnify the Indemnitee with respect thereto
shall be suspended.

         (b) With respect to any third party claim (a "Third Party Claim") which
is the subject of a Notice of Claim, the Indemnitor shall, in good faith and at
its own expense, defend, contest or otherwise protect against any such Third
Party Claim with legal counsel of its own selection. The Indemnitee shall have
the right, but not the obligation, to participate, at its own expense, in the
defense thereof through counsel of its own choice and shall have the right, but
not the obligation, to assert any and all cross claims or counterclaims it may

                                       24


<PAGE>



have. The Indemnitee shall at all times cooperate in all reasonable ways with,
make its relevant files and records available for inspection and copying by, and
make its employees reasonably available or otherwise to render reasonable
assistance to, the Indemnitor. In the event that the Indemnitor fails to timely
defend, contest or otherwise protect against any such Third Party Claim, or if
injunctive relief is sought or issued (and not dismissed within 10 days) which
would have a material adverse effect on the Indemnitee, the Indemnitee shall
have the right to defend, contest, assert cross claims or counterclaims, or
otherwise protect against, the same and may make any compromise or settlement
thereof; provided that, it does so in good faith and be entitled to all amounts
paid as a result of such third party claim, demand, suit or action or any good
faith compromise or settlement thereof. Any compromise of asserted liability by
the Indemnitor shall require the prior written consent of the party seeking
indemnification, which consent shall not be unreasonably withheld.

         8.4 Determination of Losses. In determining the amount of any loss,
liability or expenses for which any Party is entitled to indemnification under
this Section 8, the gross amount thereof will be reduced by the value of any
correlative benefit or any other benefit, including, without limitation, any tax
benefit or credit or insurance proceeds received or to be received by such.

         8.5 Limitation on Indemnifiable Claims. No VSI Indemnifiable Claim may
be asserted or otherwise maintained by VSI against RDC or 3DV in respect of
Section 8.1(a)(i) above after either (a) twelve months following the Closing
Date, or (b) in the event that the Second Closing occurs, twelve months
following the Second Closing Date (unless in either case a Notice of Claim with
respect to such Indemnifiable Claim has been made before such date), except that
any VSI Indemnifiable Claims based on the breach of the representation and
warranty of 3DV relating to the capitalization of 3DV may be made until the
expiration of a period of five (5) years following the Closing Date. No 3DV
Indemnifiable Claim may be asserted or otherwise maintained by 3DV or RDC
against VSI in respect of Section 8.2(a)(i) above after either (a) twelve months
following the Closing Date, or (b) in the event that the Second Closing occurs,
twelve months following the Second Closing Date (unless in either case a Notice
of Claim with respect to such Indemnifiable Claim has been made before such
date).

                  patents and other forms of legal protection when such actions
                  are reasonably requested by VSI, and if 3DV does refuse to
                  take such actions, 3DV shall assign to VSI all right, title
                  and interest in and to the affected patent, patent
                  application, or other legal protection to the extent, and only

3.       Manufacturing of 3DV Components
         -------------------------------

         3.1.     Notwithstanding the provisions of Article 2, 3DV shall have
                  the exclusive right to manufacture for VSI and Approved
                  Assigns, and sell to VSI and Approved Assigns, the 3DV
                  Component to be included in a Product manufactured and sold by
                  or for VSI or an Approved Assign; provided, however, that such
                  right shall be suspended with respect to any model of 3DV
                  Component, and VSI and

                                        5

<PAGE>



                  Approved Assigns may manufacture or have manufactured such
                  model of 3DV Component pursuant to the license granted in
                  Section 2.1, if (i) 3DV elects by written notice to VSI or an
                  Approved Assign not to manufacture that model of 3DV
                  Component, (ii) 3DV does not or cannot manufacture that model
                  of 3DV Component and sell such 3DV Component to VSI or an
                  Approved Assign for a price that is fair and reasonable and
                  which is at a price that is the most favorable price offered
                  or granted to any non-Affiliate of 3DV, or (iii) 3DV does not
                  or cannot supply that model of 3DV Component in quantities
                  sufficient to meet the requirements of 3DV and VSI or an
                  Approved Assign according to the pre-arranged schedule as
                  determined from time to time. Notwithstanding the foregoing,
                  the exclusive manufacturing rights reserved to 3DV shall not
                  expire or otherwise be suspended under this Section 3.1 unless
                  and until VSI or the Approved Assigns, as the case may be,
                  shall have provided reasonable notice of the basis for such
                  expiration or suspension and an opportunity to cure or
                  otherwise address the problem that would otherwise give rise
                  to such basis for the expiration or suspension of 3DV's
                  manufacturing rights.

         3.2.     At the request of VSI or an Approved Assign, 3DV shall
                  cooperate in determining specifications, performance
                  requirements and other qualities of 3DV Components necessary
                  for their integration into Products. If the design or
                  development of 3DV Components for inclusion into Products will
                  require significant research or development, 3DV and VSI or an
                  Approved Assign may enter into an agreement concerning
                  collaborative research or joint development relating thereto.
                  Such an agreement may provide terms for the design and
                  development of 3DV Components by 3DV in accordance with
                  specifications and a schedule consistent with the requirements
                  of VSI or an Approved Assign and provide for testing of 3DV
                  Components to ensure compliance with such specifications. 3DV
                  also shall cooperate in any inspection or validation of its
                  manufacturing processes that may be required by regulatory
                  authorities having jurisdiction over 3DV Components or
                  Products.

         3.3.     At any time during the term of this Agreement, VSI or an
                  Approved Assign (each a "purchaser") may order 3DV Components
                  from 3DV by submitting a purchase order therefor to 3DV. The
                  price and delivery schedule and terms of payment for such 3DV
                  Components shall be negotiated in good faith between 3DV and
                  the purchaser, as the case may be. Unless 3DV elects not to
                  supply a model of 3DV Component, 3DV shall not unreasonably
                  refuse to accept, or delay its acceptance of, any such
                  purchase order in accordance with a pre-arranged schedule
                  determined from time to time, and if 3DV does so, clauses (i)
                  through (iii) of Section 3.1 shall apply. Upon the acceptance
                  of any such purchase order, 3DV shall deliver the 3DV
                  Components ordered, in accordance with the requirements of
                  this Agreement and the specifications, delivery schedule and
                  other requirements applicable under the purchase order. All
                  such

                                        6

<PAGE>



                  deliveries shall be F.O.B. the port of export (in accordance
                  with Incoterms 1990), unless the purchase order specifies
                  otherwise.

         3.4.     Prior to each delivery of 3DV Components, 3DV shall test the
                  3DV Components in accordance with any test protocol
                  applicable under the purchase order or otherwise agreed to
                  between 3DV and the purchaser. 3DV shall give the purchaser
                  reasonable advance notice of any such testing, and the
                  purchaser shall have the right to participate in any such
                  testing. For each 3DV Component that is required to be so
                  tested, 3DV shall provide the purchaser with detailed test
                  data demonstrating that the 3DV Component conforms to the
                  applicable test criteria. Upon delivery of each shipment of
                  3DV Components, and in addition to any testing by 3DV required
                  by this Section 3.4, the purchaser shall have seven 7days
                  from the date of receipt to inspect and test all or any part
                  of such shipment to determine whether the 3DV Components in
                  the shipment (i) fail to conform to any applicable
                  requirements of this Agreement and the relevant purchase order
                  or (ii) have any defects in materials and workmanship
                  (collectively, "Nonconformities"). If the purchaser does not
                  discover any Nonconformities during such period and report
                  such Nonconformities to 3DV promptly upon discovery, the
                  purchaser shall be deemed to have accepted the shipment. If
                  the purchaser discovers and reports any Nonconformities within
                  such period, then (x) if the purchaser has so inspected and
                  tested only part of the shipment, 3DV shall so inspect and
                  test, or pay for the inspection and testing of, the remainder
                  of the shipment, and (y) 3DV shall, at 3DV's expense, either
                  (A) promptly correct all Nonconformities found through such
                  inspection and testing or (B) replace such nonconforming 3DV
                  Components with conforming 3DV Components and, at 3DV's
                  request, cost and direction, the purchaser shall ship the
                  nonconforming 3DV Components back to 3DV. Once 3DV believes
                  it has corrected such Nonconformities, the purchaser shall
                  have another seven (7) day period to determine if there are
                  any Nonconformities in the shipment. If 3DV fails to correct
                  any material Nonconformity within seven (7) days after
                  receiving notice of such Nonconformity, the purchaser may
                  reject all or any part of the shipment containing the 3DV
                  Component with the Nonconformity.

         3.5.     3DV shall invoice the purchaser for the price of any 3DV
                  Components ordered pursuant to this Article 3 upon the
                  shipment of such 3DV Components. Any properly invoiced such
                  amounts shall be payable 30 days after the purchaser's receipt
                  of 3DV's invoice or 15 days after the purchaser's acceptance
                  of the relevant 3DV Components, whichever is later.

         3.6.     For purposes of this Section 3 and solely with respect to AOC
                  as an Approved Assign hereunder, references in the definition
                  of the term 3DV Component in Section 1.1 to a camera (or
                  component thereof) or other imaging device shall mean and
                  refer to solely to an EO Element.

                  Approved Assigns are experienced in the technological fields
                  which are relevant to 3DV's technology, and they are capable
                  of evaluating the economic risk which exists under these
                  conditions.

         4.4.     NEITHER PARTY MAKES ANY OTHER EXPRESS OR IMPLIED WARRANTIES
                  OF ANY KIND (INCLUDING THE IMPLIED WARRANTIES OF
                  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE).

8.       Confidentiality
         ---------------

         8.1.     For the purpose of this Article 8, the term "Confidential
                  Information" means any information used in or relating to the
                  business of one party (the "Disclosing Party"), including but
                  not limited to information concerning the Disclosing Party's
                  research, development efforts, trade secrets, product or
                  marketing plans, vendor or customer relationships, finances,
                  business operations or affairs and any information of third
                  parties that the Disclosing Party maintains in confidence,
                  and all tangible embodiments of such information, that is
                  received by the other party (the "Receiving Party"), in any
                  form.

         8.2.     A Receiving Party shall not use the Disclosing Party's
                  Confidential Information for any purpose other than in
                  accordance with this Agreement and shall not disclose
                  Confidential Information to any person other than its
                  employees and its independent contractors subject to a
                  nondisclosure obligation comparable in scope to this Article
                  8, which employees and independent contractors have a need to
                  know such Confidential Information; provided that VSI may (i)
                  disclose 3DV Confidential Information to an Approved Assign
                  subject to a nondisclosure obligation comparable in scope to
                  this Article 8, and (ii) to the extent reasonably necessary,
                  disclose to its customers and suppliers technical information
                  concerning the performance characteristics of 3DV Components,
                  which information is of a type reasonably and customarily
                  disclosed to customers and suppliers on a non-confidential
                  basis, in connection with the manufacture, use or sale of
                  Products.

         8.3.     Notwithstanding Section 8.2, a Receiving Party may use for any
                  purpose or disclose any information that the Receiving Party
                  can show (i) is or becomes publicly known through no fault of
                  the Receiving Party; (ii) is developed independently by the
                  Receiving Party; (iii) is known by the Receiving Party when
                  disclosed by the Disclosing Party, if the Receiving Party does
                  not then

                  have a duty to maintain its confidentiality; or (iv) is
                  rightfully obtained by the Receiving Party from a third party
                  not obligated to preserve its confidentiality. A Receiving
                  Party also may disclose Confidential Information to the extent
                  required by a court or other governmental authority, provided
                  that (a) the Receiving Party gives the Disclosing Party
                  reasonable notice of the disclosure, (b) the Receiving Party
                  uses reasonable efforts to resist disclosing the Confidential
                  Information, and (c) the Receiving Party cooperates with the
                  Disclosing Party on request to obtain a protective order or
                  otherwise limit the disclosure.

         8.4.     The parties acknowledge that either party's breach of Section
                  8.2 would cause the other party irreparable injury for which
                  it would not have an adequate remedy at law. In the event of a
                  breach, the non-breaching party shall be entitled to
                  injunctive relief in addition to any other remedies it may
                  have at law or in equity.

                  publicity material, or make any form of representation or
                  statement which would constitute an express or implied
                  endorsement by the other party of any product.

         12.3.    Nothing in this Agreement shall be construed as creating a
                  partnership, joint venture or agency relationship between the
                  parties, or as authorizing either party to act as agent for
                  the other.

         12.4.    This Agreement shall be governed by and construed in
                  accordance with the laws of the State of New York of the
                  United States of America, with the same force and effect as if
                  executed and to be fully performed therein. For the
                  adjudication of any disputes arising in connection with this
                  Agreement, the parties hereby consent to the personal
                  jurisdiction of and venue in any federal or state court of
                  competent subject matter jurisdiction located in the State of
                  New York, and the parties agree that such jurisdiction and
                  venue shall be exclusive. The parties further consent to
                  service of any process relating to this Agreement by
                  registered or certified mail or by personal service. The
                  parties hereby exclude from application to this Agreement the

                  Sale of Goods.

         12.5.    The provisions of this Agreement are severable, and the
                  unenforceability of any provision of this Agreement shall not
                  affect the enforceability of the remainder of this Agreement.
                  The parties acknowledge that it is their intention that if any
                  provision of this Agreement is determined by a court to be
                  unenforceable as drafted, that provision should be construed
                  in a manner designed to effectuate the purposes of that
                  provision to the greatest extent possible under applicable
                  law.

         12.6.    The rights and remedies provided in this Agreement and all
                  other rights and remedies available to either party at law or

                  not exclusive of any other right or remedy now or hereafter
                  available at law or in equity. Neither asserting a right nor
                  employing a remedy shall preclude the concurrent assertion of
                  any other right or employment of any other remedy, nor shall
                  the failure to assert any right or remedy constitute a waiver
                  of that right or remedy.

         12.7.    Except as otherwise specifically provided in this Agreement
                  and except with respect to any Approved Assign, neither party
                  shall assign any of its rights or obligations nor subcontract
                  or otherwise delegate any of its duties under this Agreement
                  to any third party without the prior written consent of the
                  other

                   assignment or delegation in violation of this Section 12.7
                   shall be void.

         12.8.    This Agreement shall be binding upon and inure to the benefit

                  convenient references and shall not affect the meaning or
                  interpretation of this Agreement.

         12.10.   This Agreement may be executed in counterparts, each of which
                  shall be deemed to be original but all of which together shall
                  constitute a single instrument.

         12.11.   The provisions of and of Articles, 5 (for a period of twelve
                  (12) months following the date of the termination of this
                  Agreement), 8, 9, 11, and 12 shall survive the expiration or
                  termination of this Agreement; provided however that in
                  accordance with the terms of this Agreement no termination of
                  this Agreement with respect to VSI shall terminate or
                  derogate from any rights of any Approved Assign under this
                  Agreement.

         12.12.   This Agreement sets forth the entire agreement of the parties
                  concerning the subject matter hereof and supersedes all prior
                  agreements between the parties concerning the subject matter
                  hereof. Amendments to this Agreement must be in writing signed
                  by duly authorized officers of the parties. No claimed oral
                  agreement in respect thereto shall be considered as any part
                  hereof.

         12.13.   No waiver of or change in any of the terms hereof subsequent
                  to the execution hereof claimed to have been made by any
                  representative of either party shall have any force or effect
                  unless in writing, signed by duly authorized representatives
                  of the parties.
         IN WITNESS WHEREOF, the parties have caused this Agreement to be
