Licensor's forum selection for any such infringement actions.

         7.2 Exclusions. Licensor shall have no liability for any claim of
infringement based on (i) use of other than the latest release of the Licensed

release; (ii) modification of the Licensed Software by Licensee, including any
Derivative Works, if the infringement would have been avoided without such
modification; or (iii) the combination or use of the Licensed Software furnished
hereunder with materials not furnished by Licensor if such infringement would

termination given to the defaulting party.

               8.2.2 Insolvency. Either party may terminate and cancel this

Licensed Software, Source Materials and any other information provided to one
party (the "Receiving Party") by the other party (the "Disclosing Party") (which
other information is marked as "proprietary" or "confidential", or, if disclosed
orally, is reduced to writing and similarly marked and delivered to Licensee
within thirty (30) days of initial disclosure) hereunder constitutes the
confidential and proprietary information of the Disclosing Party, and that
Receiving Party's protection thereof is essential to this Agreement. The

express written consent any and all such information. Dissemination of such
information to Receiving Party's subsidiaries or affiliates is permitted,
provided that such Receiving Party agrees to be responsible for the maintenance

affiliates to execute such form of confidentiality agreement as the other party
may reasonably require consistent with the confidentiality limitations of this
Section 9.1.

persons who require access in order to carry out the permitted uses of such
Source Materials hereunder. Each copy of the Source Materials shall be marked as
the confidential and proprietary property of Licensor to which access is
restricted, and shall be kept and used solely at the Licensee's secure
development facilities ("Development Facility") under password protection.
Licensee shall ensure that the Source Materials cannot be accessed in any
insecure manner from any network, computer or similar device outside of the
Development Facility. Licensee agrees to limit access to the Source Materials
twenty four (24) hours a day strictly to those employees and independent
contractors to whom access is reasonably necessary in order to carry out the
permitted uses of the Source Materials hereunder. Licensee shall inform such
employees and contractors of Licensee's obligation to maintain the
confidentiality of the Source Materials and other confidential information.
Licensee will use its best efforts to ensure that all such employees abide by
the terms of such obligations. Licensee shall keep records of all persons who

reasonable notice, Licensee agrees to provide such records to Licensor for
review within a reasonable time period. In no event shall the Source Materials

products or for any other purpose other than the development of Licensee

                                LICENSED SOFTWARE

Licensor has developed a body of software that interacts with software on other
computers to perform network monitoring in a method known as "RMON." Licensor
markets the Licensed Software under the MeterWorks family name of products. This
software is described in Licensor's document entitled MeterWorks Agent Technical
Description version 5.0, which is incorporated by reference into this Agreement.

Licensee desires to incorporate Licensor's RMON2 software into some or all of
Licensee's products.

It is understood by both the Licensor and Licensee that the RMON software does
not stand alone. Rather, it must be incorporated into a larger body of software.
Such incorporation necessarily involves the creation of new software to act as
an interface between the RMON software and the system into which it is being
embedded. Integration of the RMON software is solely the responsibility of the
Licensee.

                        LICENSE FEE AND ROYALTY PAYMENTS


A.       License Fees.

         Siegler Technologies is licensing Hifn's MeterWorks RMON 2 agent, and
MeterFlow, including the MeterFlow Performance Metrics in return for a licensing
fee of $300,000. See MeterFlow License Agreement between Siegler Technologies
and Hifn dated August 31, 2002 for additional terms of payment.

B.       Royalties.

         A royalty will be paid for each Licensee device that includes an
implementation of the MeterFlow Object Code: $8 each.

C.       Royalty Schedule.

         Royalties will be considered paid in full once cumulative royalty
payments for MeterWorks. MeterFlow and MeterFlow PM total: $500,000, inclusive
of any royalty payments per Section B immediately above or with respect to any
royalty payments made by Licensee or its successor in interest pursuant to
Licensee's MeterFlow license agreement with Licensor executed of even date
herewith; in no event shall Licensee be obligated to pay royalties in excess of
$500,000 cumulatively with respect to the Licensee Products; after payment of
said $500,000 all Licensee Products shall be deemed fully paid up. See Schedule
D, License Fee and Royalty Payments in the MeterFlow License Agreement dated of
even date herewith.

D.       General Terms.

         1. Payments and Accounting. With respect to the royalties set forth
herein, Licensee shall keep complete and accurate records. These records shall
be retained for a period of three (3) years from the date of payment,
notwithstanding the expiration or other termination of this Agreement. Licensee
agrees to permit its directly related financial records and accounts to be
examined, not more than once a year, during normal business hours, to verify the
amount of royalties payable to Licensor under this Agreement. Prompt adjustment
shall be made by Licensee to Licensor corresponding to the net amount of any
underpayment of royalties due hereunder. If such examination reveals an
underpayment of more than five percent (5%), then Licensee shall promptly
reimburse Licensor for the cost of the examination and for any amounts
underpaid. Until full payment of the aggregate $500,000 royalty amount, the
actual annual royalty payment shall be the greater of the total royalties
generated from licenses or the minimum annual commitment.

         2. Reports and Payment Terms. Within thirty (30) days after the
beginning of each quarter following first customer shipment during the term of
this Agreement, Licensee shall furnish to Licensor a statement in suitable form
showing all products subject to royalties hereunder which were sold, leased,
licensed, transferred or otherwise disposed of during such fiscal quarter, and
the amount of royalties payable thereon. If no products are subject to




                                       D-1
<PAGE>

royalties, then that fact shall be shown on such statement. Notwithstanding the
minimum royalty payments described in the schedule above will be paid within 30
days after the beginning of each quarter following the first customer shipment.
This first quarter is estimated to be the second quarter of calendar year 2003.

         3. Withholding Taxes. All payments by Licensee shall be made free and
clear of, and without reduction for, any withholding taxes. Any such taxes which
are otherwise imposed on payments to Licensor shall be the sole responsibility
of Licensee. Licensee shall provide Licensor with official receipts issued by
the appropriate taxing authority or such other evidence as is reasonably
requested by Manufacturer to establish that such taxes have been paid.

cannot be avoided by alternate methods or which otherwise causes a shutdown of
the essential operations which are dependent on the Product Software.

                  4.2.2. "Class II Priority" means a problem which requires a
reset of product and may cause serious shutdown of some of the operations, which
are dependent on the Product Software. The fix of the problem is very cumbersome
and may involve some reprogramming.

minor inconvenience to the end user including, but not limited to, misspelled
error messages and documentation errors.
