9  NON-DISCLOSURE

     By virtue of this Agreement, each party may have access to information of
the other party which is considered confidential and proprietary. For
convenience, all such information will be called "Confidential Information."

     Confidential Information shall include the source code, source code
materials, and all other information, documentation, designs, concepts,
inventions, trade secrets, know-how, private processes, customer lists or other
materials provided by either party in written or other tangible form and clearly
marked as proprietary or confidential. Notwithstanding the foregoing,
Confidential Information shall not include information which a) is at the time
of disclosure to the receiving party in the public domain or subsequently
becomes part of the public domain without a breach of its confidentiality
obligations hereunder by the receiving party; b) was in the receiving party's
lawful possession prior to the disclosure and had not been subject to
limitations on disclosure; c) is lawfully disclosed to the receiving party by a
third party without any obligation of secrecy to the disclosing party, of which
the receiving party is aware.

     The parties agree, both during the term of this Agreement and for a period
of five (5) years after termination or expiration of this Agreement for any
reason, that all Confidential Information owned or legally controlled or used by
one party and disclosed to the other party shall remain solely the property of
the disclosing party (and shall thereafter remain solely the property of the
disclosing party), and its confidentiality shall be maintained and protected
by the other party with the same effort used to protect its own confidential
information. Except to the extent required by this Agreement, both parties agree
not to duplicate in any manner the other's Confidential Information for any
purpose other than the implementation of this Agreement.

     In the event that one of the parties, or anyone to whom Confidential
Information is disclosed pursuant to this Agreement is or becomes legally
required or compelled to disclose any of the Confidential Information, such
party shall provide the other party with prompt notice so that such other party
may seek a protective order or other appropriate remedy and/or waive compliance
with the provisions of this Paragraph. In the event that such protective order
or other remedy is not sought or obtained or in the event that the other party
waives compliance with the provisions of this Paragraph, the compelled party
will furnish only that portion of the Confidential Information which it is
legally required to disclose and will seek to obtain reliable assurance that
confidential treatment will be accorded the Confidential Information.

     During the term of this Agreement it is not the intent of Landis & Gyr to
independently develop or acquire software within the Computer Integrated
Facilities Management (CIFM) industry which is functionally similar to the
Software. In the event Landis & Gyr does elect to develop its own software or to
obtain software through the undertaking of an agreement with a third party,
Landis & Gyr shall notify Innovative Tech at the inception of its decision to
develop or acquire similar software and Innovative Tech shall then have the
right, to be exercised by written notice to Landis & Gyr within ninety (90) days
from the receipt of such notice, to terminate this

Agreement in which event all marketing and distribution license prices shall
continue as provided in this Agreement, but the parties shall otherwise treat
this Agreement and handle existing customers in the same manner as described
under Paragraph 14.1 and 14.6

     Results of benchmark tests may not be disclosed unless Innovative Tech
consents to such disclosure in writing.

     Nothing provided in this Agreement shall prohibit Innovative Tech from
selling any End User any products of Innovative Tech.

     Landis & Gyr and Innovative Tech shall not disclose the terms and
conditions of this Agreement; provided however, that either party may disclose
such terms and conditions (a) when required by law, and (b) to its professional
advisors and financial professionals. For news release or public announcements
regarding this Agreement, each party shall obtain consent from the other party
prior to publication. Such consent shall not be unreasonably withheld.

     Landis & Gyr and Innovative Tech acknowledge that money damages would not
be a sufficient remedy for any breach of this Agreement and that the other
party shall be entitled to specific performance and injunctive relief as
remedies for any such breach in addition to all other remedies at law or equity.

10   MAINTENANCE AND SUPPORT

     10.1  During the term of this Agreement, Landis & Gyr shall provide the

Innovative Tech a license price of 200.00 USD (two hundred) for each
Demonstration License as per 3.6 above.

        10.3    End User Program Errors shall be handled as follows:

                10.3.1  Upon Innovative Tech's receipt of an error reported by
an End User to Landis & Gyr's designated technical contact, and which cannot be
handled under paragraph 10.1 above, Innovative Tech shall take corrective
action so as to remedy the reported problems within the time schedule outlined
in 10.3.2

                10.3.2  Innovative Tech shall respond to all requests for
service made by Landis & Gyr within four (4) hours following Landis & Gyr's
first call to Innovative Tech help-line, and Innovative Tech and Landis & Gyr
shall cooperate in the identification, verification and possible resolution of
problems with the Software. For any "Critical Error" reported by Landis & Gyr,
Innovative Tech shall either correct such Critical Error or supply Landis & Gyr
with a satisfactory work-around within five (5) business days. In any event,
all Critical Errors shall be corrected within ten (10) business days following
Landis & Gyr's first call to the Innovative Tech Help Line. For any
"Non-Critical Error" reported by Landis & Gyr, Innovative Tech shall correct
such Non-Critical Error in the future releases of such module. A "Critical
Error" shall mean any Error which materially interferes with the normal use and
operation of the Software. A "Non-Critical Error" shall mean any Error other
than a critical error.

        10.4    It is intended that Landis & Gyr and Innovative Tech will work
within the framework of the Maintenance and Support guidelines. In the event
that an exceptional circumstance arises, the parties will discuss the
circumstances and mutually agree on the correct course of action to take.
Exceptions may include, but not be limited to, impossibility of Innovative Tech
to perform, severe impact on one of Landis & Gyr's major customers or potential
sales, or availability of a more efficient approach.

        10.5    Innovative Tech agrees to provide support, in addition to that
specified herein, based upon Landis & Gyr's request, in a expeditious manner,
and at charges to be paid by Landis & Gyr which shall not exceed those

        10.6    Landis & Gyr agrees to pay to Innovative Tech an annual
maintenance and support fee of seventeen (17) percent of the cumulative license
prices paid in accordance with Exhibit A. This fee will be applied to cover
labor costs incurred by Innovative Tech for performing second line support and
for providing product Updates to End Users at no additional charge. The
maintenance and support fee shall be payable on every anniversary date of this
Agreement.


11      WARRANTY        

        Innovative Tech warrants for a period of ninety (90) days from

12   PATENT OR COPYRIGHT INFRINGEMENT AND INDEMNITY

     12.1  Innovative Tech will defend, indemnify and hold harmless Landis & Gyr
against a claim that the Software was created in part by violation of the
protected trade secret of another or infringe a patent or copyright and will pay
resulting costs, damages and attorney's fees provided that:

     (a)  Landis & Gyr notifies Innovative Tech within thirty (30) days of the
claim;

     (b)  Landis & Gyr cooperates with Innovative Tech in the defense; and

     (c)  Innovative Tech has sole control of the defense and all related
settlement negotiations.

     12.2  If such claim occurs, or in Innovative Tech's opinion is likely to
occur, Landis & Gyr agrees to permit Innovative Tech, at its option and expense,
either to procure for Landis & Gyr the right to continue using the Software or
to replace or modify same so that it becomes noninfringing.

     12.3  Innovative Tech shall have no obligation to defend Landis & Gyr or
pay costs, damages or attorneys' fees for any claim based upon use of other than
a current, unaltered Release of the Software if such infringement would have
been avoided by the use of a current, unaltered Release of the Software. Should
such infringement occur, Innovative Tech shall only be obliged to remedy the
infringing Software by replacing at their own costs the older Release with the
current Release. Innovative Tech shall have no obligation to defend Landis & Gyr or pay costs, damages or attorneys' fees for any claim which results from
negligence or breach of this Agreement by Landis & Gyr. The concept of
"comparative negligence" shall be used to allocate the parties liability based
on their relative responsibility for any infringement claim.

Agent. The Board shall consist of three (3) members of the Association, one (1)
of which shall be chosen by each party and one (1) of which shall be chosen by
the two (2) arbitrators chosen by the parties. The sole question before the
Board shall be whether or not there existed, at the time Landis & Gyr requested
Escrow Agent to deliver a Code Copy to it pursuant to Section 5 above, one or
more of the conditions specified in Section 5. Each party shall have two (2)
hours to present the reasons which justify its position. After each party has
presented its position, each party shall have an additional one (1) hour for
rebuttal or responding. The parties agree that the Board shall have either
authority to grant injunctive or other equitable relief and that the decision
of the Board shall be final and binding and shall be immediately delivered to
Landis & Gyr and Innovative Tech. If the Board finds that none of the
conditions specified in Section 5 above existed at the time of Landis & Gyr's
request to Escrow Agent, and that accordingly such request was not properly
given by Landis & Gyr, then Escrow Agent shall not deliver a Code Copy to
Landis & Gyr. All fees and charges by the Association shall be split equally
between them. The provisions for arbitration described above shall represent
the exclusive means for resolving a dispute arising from a request for delivery
of a Code Copy pursuant to Section 5, but shall not preclude either party from
instituting a legal action against the other party for performance of any other
obligations under this Agreement.

7       Landis & Gyr and Innovative Tech agree that the Code and any Code Copy
delivered to Landis & Gyr under the provisions of this Agreement shall
constitute confidential information of Innovative Tech and no proprietary
rights thereto shall be transferred to Landis & Gyr by this Agreement or by the
delivery of any Code Copy to Landis & Gyr pursuant to this Agreement except as
expressly provided herein. Landis & Gyr shall not make any disclosure of any
such confidential information to anyone except employees of Landis & Gyr or
third parties subject to Landis & Gyr's control, which third parties shall be
deemed to include any vendor performing outsourcing of facilities management
functions for Landis & Gyr; Landis & Gyr shall

make such disclosure only when reasonably necessary for the use and maintenance
of Landis & Gyr's facilities management system. Landis & Gyr shall
appropriately notify each such employee or third party to whom such disclosure
is made of the confidential and proprietary nature of such confidential
information, shall use reasonable efforts to ensure that the employees or third
party maintains and protects the confidentiality of the disclosed information,
and shall enter into a confidentiality agreement with each third party
confirming the confidentiality restrictions set forth herein. Landis & Gyr 
agrees that these obligations will survive any termination of this Agreement,
In the event that the Code and any Code Copy is delivered to Landis & Gyr under
the provisions of this Agreement, then Landis & Gyr's license for the Software
shall immediately be amended to authorize Landis & Gyr or any vendor performing
outsourcing or facilities management functions for Landis & Gyr to develop 
derivative works from or modify the Software and to reproduce and distribute 
the same internally.
        
8       Escrow Agent may resign its duties hereunder upon not less than thirty
(30) days notice; in which case, Innovative Tech shall agree upon the identity
of a successor Escrow Agent, subject to the consent of Landis & Gyr, which
consent shall not be unreasonably withheld. Upon notice to Escrow Agent and
Landis & Gyr of the identity of the successor Escrow Agent, Escrow Agent shall
deliver the Code Copies to its successor on the effective date of its
resignation. If Innovative Tech has failed to designate a successor Escrow 
Agent acceptable to Landis & Gyr before the effective date of the Escrow
Agent's resignation, Escrow Agent may, by notice to Innovative Tech and Landis
& Gyr, designate the successor Escrow Agent and deliver the Code Copies to such
successor on the effective date of the resignation. Any successor Escrow Agent
shall be bound by the terms of this Agreement.

9       (a)  Each of Innovative Tech and Landis & Gyr, jointly and severally,
agrees to absolutely and irrevocably remise, release, and forever discharge
Escrow Agent from any and all actions, suits, payments, liabilities, claims and
demands relating in any way to the performance of its duties hereunder except
for such actions based on claims caused solely by the willful misconduct or
negligence of Escrow Agent.

        (b)  Each of Innovative Tech and Landis & Gyr, jointly and severally,
agrees to indemnify and hold harmless the Escrow Agent in respect of any
liability for taxes imposed on the Escrow Agent (other than taxes imposed on the
income of Escrow Agent) relating to the assets held by Escrow Agent pursuant to
this Agreement.

10      Each party shall promptly notify all other parties by Mail of any
change in its address listed above. Any correspondence or notifications to
such party pursuant to this Agreement shall thereafter be sent to such new
address by Mail.

11      This Agreement shall commence on the date hereof and shall terminate
upon one of the following conditions: mutual agreement between the Escrow Agent,
Innovative Tech and Landis & Gyr, upon delivery of the Source Code to Landis & Gyr, or when the Strategic Marketing Agreement is terminated.

12      This Agreement and the rights and obligations hereunder shall be
construed in accordance with and governed by the laws of the Commonwealth of 
Pennsylvania.

13  This Agreement constitutes the entire understanding between parties hereto
and the parties shall not be bound by any agreements, understandings or
conditions respecting the subject matter hereof other than those expressly set
forth and stipulated in the Agreement.

14  This Agreement shall bind and inure to the benefit of the parties hereto
and their respective successors and assigns.

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