number of supervisory personnel who will be involved in installations
utilizing the Subject Matter to be trained by the Licensor specifically in
the utilization of the Subject Matter; and no such installations shall be
initiated by the Contractor unless and until such supervisory personnel are

Permitted Uses.  The Licensor shall thereafter provide an adequate continuing
technical and engineering support capability to support the efforts of the
Contractor, the content, extent, and frequency of which shall be solely at
the discretion of the Licensor; except that the Licensor will conduct an
annual training seminar with respect to application of the Subject Matter in
the Permitted Uses, and the Contractor agrees to have, at its expense, at
least one supervisory representative in attendance.  The Contractor shall not
be obligated to pay any fees or other charges to the Licensor in exchange for
the foregoing training.  At the request of the Contractor and subject to

operation of the Subject Matter to assist and render advice to the Contractor
subject to payment by the Contractor of all reasonable direct traveling and
hotel expenses and a reasonable per diem rate which shall be agreed upon
between the parties at a location agreed upon by both parties.

persons and damage to property.  The Contractor also agrees to have the
Licensor named as an additional named insured under the above described
policy or policies and to cause the Licensor to be furnished with a
Certificate of Insurance which shall contain a requirement that the Licensor
be notified 30 days prior to any cancellation or any reduction in coverage
limits.  The insurance required above shall commence prior to the time the
Contractor commences operations under this Agreement and shall continue in
force throughout the Term.
      4.06  Taxes; Compliance with Laws.
      The Contractor shall promptly pay when due all taxes and assessments
against the premises or the equipment used in connection with the
Contractor's business, and all liens or encumbrances of every kind or
character created or placed upon or against any of said property, and all
accounts and other indebtedness of every kind incurred by the Contractor in
<PAGE>
the conduct of said business, the failure to pay which would have a
materially adverse effect on the ability of the Contractor to perform its
obligations hereunder.  The Contractor shall have the right to contest the
validity or amount of any assessment, tax, lien or encumbrance, provided that
the Contractor shall: (1) give the Licensor notice of its intention to
contest; (2) diligently prosecute such contest; and (3) at all times
effectively stay or prevent any official or judicial sale of such property or
any thereof by reason of the non-payment of any lien, encumbrance, tax, or
assessment.  The Contractor shall comply with all applicable federal, state,
county and municipal laws and regulations, now in effect or hereinafter
enacted, including, without limitation, all environmental laws and all
occupational safety and health laws, the failure to comply with which would
have a materially adverse effect on the ability of the Contractor to perform
its obligations hereunder, and shall timely obtain any and all permits,
certificates, or licenses necessary for the full and proper conduct of its
business.

      The Contractor shall maintain a high standard of quality in all
installations made and in all other activities under the Service Mark or
Trademark.  To ensure the maintenance of such standards, the Licensor may
periodically inspect the Contractor's practice of the methods of the Subject
Matter at the Licensor's own expense and without unreasonable inconvenience
to the Contractor.  The Contractor shall cooperate fully with the Licensor in
any such inspections in its practices of the methods of the Subject Matter
made by the Licensor.  At all times the Contractor shall exert diligent
effort to practice the methods and techniques included in the Subject Matter
in accordance with the best available technical information and advice
received from the Licensor.  The Contractor hereby agrees that failure by the
Licensor to exercise any right of inspection or any other right under this
Section 4.08 shall not operate subsequently to preclude exercise by the
Licensor of this right, and that failure of the Contractor to permit such
inspections or to maintain such standards shall constitute a material breach
of this Agreement and shall form the basis of termination hereof, but solely
in accordance with the notice and cure provisions of Article VI hereof.

terminated by the Licensor in the event the Contractor:
            (i)   becomes insolvent or a petition in bankruptcy is filed by

      provided by this agreement;
            (iv)  fails to pay when validly due any sum owed to the Licensor

accordance with such provision and, in the case of the first such breach in
<PAGE>

written notice from the Licensor to the Contractor, then in any such event,
this Agreement shall automatically terminate.
      (c) No termination under this Section 6.02 shall limit or affect any
other right or remedy of the Licensor, including the right to damages
resulting from the Contractor's breach.
      6.03 Consequences of Expiration or Termination.
      (a) Upon expiration or termination of this Agreement, the Contractor
shall promptly pay the Licensor all amounts then due under this Agreement,
terminate all use by it of any service mark, tradenames, trademark,
certification mark or corporate name that includes any of the forgoing words;

any copies which it has made of the same.  Following termination, the
Contractor shall continue to be obligated to provide all after sales services
for which it has theretofore contracted, including the honoring of all
contract warranties.  Should the Contractor fail to fulfill such obligations,
and should the Licensor, in its reasonable discretion after notice to the
Contractor, whether for reason of preserving product goodwill or otherwise,
choose to perform any such obligations (this paragraph in no way to be
construed as an assumption by the Licensor of any obligations for which it is
not specifically contractually responsible), then the Contractor shall
promptly reimburse the Licensor the reasonable charges issued by the Licensor
to the Contractor of performing such obligations of the Contractor.  If the
Contractor is a corporation having the word ULTRALINER as a part of its
corporate name, the Contractor shall, within 60 days of termination, amend

costs and expenses, including reasonable attorney's fees, incurred by such
other non-defaulting party in obtaining injunctive or other relief to enforce
the provisions of this Agreement.  Notwithstanding the foregoing, in any
dispute under this agreement, the ultimate prevailing party shall be entitled
to recover from the other party its reasonable attorney's fees.  No right or
remedy herein conferred upon or reserved to either party is exclusive of any
other right or remedy herein or by law or equity provided or permitted; but
each shall be cumulative of every right or remedy given hereunder.  In
addition to whatever remedy or remedies a party may have by way of damages
for violation of the provisions of this Agreement and/or expiration or
termination of the same, such party shall also have the right to injunctive
relief to enforce the provisions of this Agreement.
      (c) In the event of the termination of this Agreement by the Licensor
or Contractor as a consequence of any event described under sub-paragraphs
(i), (iii), or (iv) or Paragraph (a) of Section 6.02 or 6.01 hereof, the

in such case to the constraints of the Licensor's business and its other
obligations.

Licensor's knowledge, all information given will be correct in all material
respects.  However, it is impossible to anticipate every possible variation
in the manner of use or the conditions under which the Contractor will apply
the Product and Licensor makes no warranty or representation of results which
the Contractor will attain, and, except as stated above, shall under no
circumstances be held responsible for any such results that occur as a
consequence of a departure from the instructions provided by the Licensor or
from negligence or malfeasance on the part of the Contractor.
      (b) Licensor does warrant that the Product will comply with Licensor's
standard specifications and will perform in the Permitted Uses as described

such uses on account of manufacturing defects.  In the event of any such
failure, the liability of the Licensor shall be limited to the replacement of
the product that has failed.

      THE FOREGOING WARRANTY IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES

      Further, except as expressly set forth in this Article VII, the
Licensor shall not be held responsible for use by the Contractor of any
Product, Materials, Apparatus, Know-how, Patents Rights or Confidential
Material in such manner as to infringe any patent, trademark or copyright
owned by another.  The Licensor warrants that it has rights to the patents
pertaining to the Materials subject to no lien, encumbrance or charge
whatsoever.
<PAGE>
      7.02 Forbearance by Contractor.
      The Contractor expressly covenants that during the Term and after the

directly, contest or aid in contesting the validity, or the ownership or
licensing by the Licensor, of the Subject Matter, the Know-how, any Patent
Rights and any Copyrights, as well as any trademarks, service marks, trade
names, and copyrights described under Section 2.02, or the limitation of the
Contractor's right with respect to the Subject Matter by the terms and
provisions of this Agreement.  The Contractor agrees promptly to notify the
Licensor of any claim, demand, suit or litigation based upon or arising from,
or of any attempt by any other person, firm or corporation, to use the
Subject Matter, the Know-how, the Patent Rights, any Copyrights or any such
other service and/or trademarks, tarde names, copyrights licenses hereunder
without the consent of the Licensor, or any other Confidential Material or
trademark, servicemark, symbol, trade name, copyright or variation thereof,
in which the Licensor has a proprietary interest.  The Contractor agrees also
promptly to notify the Licensor of any material litigation instituted by the
Contractor, or by any person, firm, corporation or governmental agency
against the Contractor.  In the event the Licensor, pursuant to the terms of
this Agreement hereinafter set forth, undertakes the defense or prosecution
of any litigation except in the case of the Contractor, the Contractor agrees
to execute any and all documents and do such acts and things which may, in
the opinion of counsel for the Licensor, be necessary or of assistance to
carry out such defense or prosecution, either in the name of the Licensor or
in the name of the Contractor, as the Licensor shall elect and to cooperate
with the Licensor in its efforts to protect the Copyrights, as well as any
trademarks, service marks, trade names, and copyrights described under
Section 2.02.
      7.03 Defense of Patent Rights and Trademarks.
      Notwithstanding any other provision herein, the Licensor does hereby
agree, at its expense, to defend Patent Rights, if any, and the servicemarks
and trademarks herein described by such means as it in its sole discretion
may determine appropriate, including but not limited to, patent or trademark
infringement suits, as the case may be.
      The Licensor reserves, however, the exclusive right to determine
whether a patent infringement has occurred, and whether a trademark
infringement has occurred, and whether litigation or other action is
appropriate or feasible.  Subject to approval by the Licensor and control by
the Licensor of any and all proceedings initiated as a result thereof, the
Contractor, with its own counsel reasonably acceptable to the Licensor, may,
at its option and expense, take steps to defend the Patent Rights, any
service mark or trademark and the Contractor's rights thereunder.
      7.04 Indemnification by Contractor.
      The Contractor agrees to indemnify, defend and hold the Licensor
harmless from any and all claims, including, without limitation, for bodily
injury (including death), personal injury and damage to property of the
Contractor, the Licensor and/or others, which arise from the alleged
negligence or malfeasance of the Contractor or from the existence or use of
Materials and/or Apparatus acquired from sources other than the Licensor or
which are produced by the Contractor.

nor offer, permit, or suffer the same.  Any such assignment permitted by the
Licensor to any Affiliate of the Contractor shall be made on the express
condition that the assignor guarantees the performance of its assignee

subcontract of this Agreement not having the aforesaid consent shall be null
and void and shall constitute a material default hereunder.  If any event has
occurred or fact or circumstance exists which, but for the giving of notice
passage of time or otherwise, would constitute a default hereunder, the
Contractor shall so advise any proposed transferee hereunder.
      Upon approval of any assignment, transfer, or conveyance of the
Agreement by the Licensor, the assignment, transfer, or conveyance shall be
completed without additional License fees or other costs being assessed to
the Contractor.
