this Section 4.03 shall in no manner operate to limit any obligation of the
Contractor contained elsewhere in this Agreement.
            (i)   It is specifically understood and agreed that nothing
herein provided shall be construed as requiring the Operator to operate in
accordance with any designated marketing plan or system, which, except for
the maintenance of high standards of quality with respect to the Subject
Matter and its usage, the exercise of diligence and the performance in
accordance with the terms and conditions hereof, are left to the
determination of the Operator.

      Promptly upon execution of this Agreement, and continuing throughout
the Term, the Licensor thereupon shall fully disclose to the Contractor all
Know-how, and any Patent Rights and Copyrights, intended to be utilized in

Term (and in all events prior to any application by the Contractor of the
Subject Matter), the Contractor, at its expense, shall require an adequate
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
certified by the Licensor as qualified to utilize the Subject Matter for the
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
availability, the Licensor will provide a technician experienced in the
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 or
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
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

its obligations hereunder, and shall timely obtain any and all permits,
certificates, or licenses necessary for the full and proper conduct of its
business.
      4.07  Standards and Inspection.

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.

ARTICLE V - IMPROVEMENTS; SECRECY

applications for copyrights or patents, assignments of copyrights or patents

attorneys may deem necessary or desirable, and the aforesaid obligation shall

representatives of the Contractor.

Contractor against third parties, which shall be exercised in consultation
with and subject to the Licensor's approval, which approval shall not
unreasonably be withheld, the Contractor hereby constitutes and appoints the

hereof in accordance with such provision and, in the case of the first such
breach in any calendar year, such failure shall continue for a period of 30
days after 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, tradename, trademark
certification mark or corporate name that includes any of the foregoing
words: avoid all subsequent use of all service marks, tradenames, trademarks,
certification marks or corporate names likely to be confused with ULTRALINER
as well as all stationery, invoices, signs or other visual devices displaying
or otherwise associated with ULTRALINER; terminate all use of the Subject
Matter and the Licensor's Confidential Material, as well as the use and sale
of any products under any Patent Rights or Copyrights or the Know-how; and
assign to the Licensor free of charge, any and all rights and claims to any
and all rights arising from the use of ULTRALINER, or any combination
involving ULTRALINER, the above mentioned Corporate rights in the Territory;

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
its corporate name to remove the word ULTRALINER therefrom.
            (b)   Each party hereto shall promptly pay to the other party all
damages, costs and expenses, including reasonable attorney's fees, incurred
by such other party by reason of default on the part of such party hereto,
whether or not such default occurred prior to or subsequent to the
termination or expiration of this Agreement, and said sum shall include all
<PAGE>
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 (vi) of Paragraph (a) of Section 6.02 or 6.01
hereof, the Licensor shall thereafter assist the Contractor in disposing of
any Materials or Apparatus then in the possession of the Contractor,
including but not limited to the sale of excess inventory to other qualified
Licensees, subject in such case to the constraints of the Licensor's business
and its other obligations.  
            (d)   Licensor shall supply to the Contractor, at the current
rates and prices, any and all materials or apparatus Contractor may need to
complete any outstanding projects or projects that may have been bid prior to
the termination, but not awarded, and a bid bond was provided by the
Contractor, provided the Contractor is not in default of any provision of
Section 6.02.

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.

the performance in 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.

LAW OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY OF
FITNESS FOR ANY PURPOSE OTHER THAN AS IS CONTEMPLATED BY THIS AGREEMENT.

Licensor shall not be held responsible for use by the Contractor of any
Product, Materials, Apparatus, Know-how, Patents Rights or Confidential

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.

      The Contractor expressly covenants that during the Term and after the
expiration or termination thereof, the Contractor shall not, directly or in-
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, trade 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 arrangement 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,
<PAGE>
at its option and expense, take steps to defend the Patent Rights, any
service mark or trademark and the Contractor's rights thereunder.

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.

ARTICLE VIII - LIMITED ARBITRATION PROCEDURES

      8.00  Limited Arbitration Procedures
      Any controversy or claim arising out of or relating to the subject
matter of this contract, or the breach thereof, shall be submitted to
arbitration in accordance with the rules of the American Arbitration
Association, and the results thereof shall be binding on the parties.

ARTICLE IX - INDEPENDENT CONTRACTORS

      9.00  Independent Contractors.
      This Agreement does not constitute either party as an agent, legal
representative, joint venturer, partner, employee, or servant of the other
party for any purpose whatsoever; and it is understood between the parties
hereto that each party is an independent contractor and is in no way
authorized to make any contract, agreement, warranty or representation on
behalf of the other party, or to create any obligation, express or implied,
on behalf of the other party.  The Contractor shall prominently  display in
its place of business a certificate from the Licensor stating that said
business is operated by the Contractor as a licensee of the Licensor, and not
as an agent thereof.

ARTICLE X - TRANSFER OR ASSIGNMENT OF LICENSE.

      10.00  Transfer or Assignment of License
      Subject to the requirements of the immediately succeeding sentence, the
Contractor, if not in default under this Agreement, shall have the right to
sell and assign its rights hereunder.
      This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, with the specific
understanding and requirement that the Contractor, without the Licensor's
prior written consent, which consent shall not unreasonably be withheld,
shall not, by operation of law or otherwise, sell, assign, transfer, convey,
subcontract, give away, or encumber to any person, firm or corporation, its
interest in this Agreement, or its interest in the license granted hereby,
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
strictly in accordance with the terms and provisions hereof.  In the event
that the Contractor is a corporation or partnership, should beneficial
ownership of an amount of the outstanding capital stock or other interest, as
the case may be, or other indicia of ownership in the Contractor be conveyed
so as to effect a Change in Control of the Contractor, whether by sale,
conveyance, operation of law or otherwise, without having first obtained the
written consent of the Licensor to transfer the license, which consent shall
not unreasonably be withheld, the Licensor shall at its option have the right
to immediately terminate this Agreement or enter into a new Agreement with
the Change in Control.  Any purported assignment, transfer, conveyance or
<PAGE>
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 circumstances 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.

term and condition of this Agreement, including, but not limited to, the
maintenance of high standards of quality and service.

      It is the intention of the Licensor and the Contractor that the
provisions of this Agreement shall be enforced to the fullest extent
permissible under the laws and public policies of each jurisdiction in which
enforcement is sought, but that the unenforceability of any provisions of
this Agreement shall not render unenforceable, or impair, the remainder of
this Agreement.  In the event that any one or more of the provisions of this
Agreement is, or are, held to be invalid, it is agreed between the parties
that, if legally practical said provision or provisions shall be considered
never to have been contained herein and this Agreement shall otherwise
continue in force and effect.  To the extent that the provisions of this
Agreement provide for periods of notice less than those required by
applicable law, or provide for termination, cancellation, non-renewal or the
like other than in accordance with applicable law, such provisions shall, to
the extent such are not in accordance with applicable law, not be effective,
and the Licensor shall comply with applicable law in connection with each of
these matters.  References in this Agreement to the materiality of any terms
hereof are not intended to be exhaustive of all such material terms, and
shall not preclude any other provision from construction as or constituting a
material provision hereof.
      11.05  Entire Agreement.

hereto with respect to the Subject Matter hereof and supersedes all prior

one and the same agreement.
      11.09  Standard of Dealing.
      The parties shall perform such further acts and deeds as shall be
necessary to effectuate the purposes of this Agreement and shall, in their
respective performance hereunder, at all times deal in the utmost good faith
with each other.
      11.10  Most Favored Licensee.
      In the event the Licensor subsequently enters into any license
agreement for the Subject Matter in the Permitted Uses within the United
States or its territories, and such license contains terms materially more
favorable to the licensee thereunder than are contained herein with respect
to the Contractor, then at the option of the Contractor, this agreement shall
be amended to incorporate such more favorable terms.
      IN WITNESS HEREOF, THE PARTIES HERETO HAVE CAUSED THIS CONTRACTOR
