                         Notes to Financial Statements

1.   Fiscal Periods

The fiscal year of Benthos, Inc. (the Company) ends on September 30 each year.
Interim quarters are comprised of 13 weeks unless otherwise noted and end on the
Sunday closest to December 31, March 31, and June 30.  All references in the
unaudited condensed consolidated financial statements to fiscal periods ended on
December 31, March 31, or June 30 mean the interim quarters referred to above.

2.   Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared by the Company pursuant to the rules and regulations of the Securities
and Exchange Commission regarding interim financial reporting.  Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements and should be
read in conjunction with the consolidated financial statements and notes thereto
for the fiscal year ended September 30, 1998, included in the Company's
previously filed Form 10-KSB.  The accompanying condensed consolidated financial
statements reflect all adjustments (consisting solely of normal, recurring
adjustments) which are, in the opinion of management, necessary for a fair
presentation of results for the interim periods presented.  The results of
operations for the interim period are not necessarily indicative of the results
to be expected for the full fiscal year.  Certain reclassifications have been
made to the 1998 financial statements to conform with the 1999 presentation.

3.  Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market and
consist of the following:

4.  Earnings Per Share                            

Basic earnings per share excludes dilution and is computed by dividing net
earnings by the weighted average number of common shares outstanding for the
period. Diluted earnings per share reflects the potential dilution that could
occur if securities or other contracts to issue common stock were exercised or
converted into common stock. Diluted earnings per share is computed based upon
the weighted average number of common shares and dilutive common equivalent
shares outstanding. Common stock options have a dilutive effect on earnings per
share in all periods and are therefore included in the computation of diluted
earnings per share. The Company has stock options for 91,500 shares of common
stock at an average exercise price of $13.60 in the thirteen week period ended
December 31, 1998, which have not been included in basic or diluted earnings per
share as they are antidilutive.

</TABLE>

Sales. Net sales increased by 22.9% in the first quarter of fiscal year 1999 to
$3,835 as compared to $3,120 in the first quarter of fiscal year 1998. Sales of
the Undersea Systems Division increased by 109% to $3,097 in the first quarter
of fiscal year 1999 as compared to $1,479 in the first quarter of fiscal year
1998. The increase resulted mainly from higher sales of hydrophones in the first
quarter of fiscal year 1999 as compared to the first quarter of fiscal year 1998
related to the Company's transition to its new Geopoint hydrophone product.
Sales of the Container Inspection Systems Division decreased by 55% to $738 in
the first quarter of fiscal year 1999 as compared to $1,641 in the first quarter
of fiscal year 1998. The decrease resulted largely from the timing of project
orders.

Cost of Sales.  Cost of sales increased by 76.9% to $2,344 in the first quarter
of fiscal year 1999 as compared to $1,325 in the first quarter of fiscal year
1998.  As a percentage of sales, cost of sales was 61.1% in the first quarter of
fiscal year 1999 as compared to 42.5% in the first quarter of fiscal year 1998.
The increase in the cost of sales dollars and percentage is attributed primarily
to the higher sales mix of the products of the Undersea Systems division which
carry a higher cost than the products of the Container Inspection Systems
Division.

                                                                               9

Gross Profit. Gross Profit decreased by 16.9% to $1,491 for the first quarter of
fiscal year 1999 as compared to $1,795 for the first quarter of fiscal year
1998.  As a percentage of sales, gross profit was 38.9% in the first quarter of
fiscal year 1999 as compared to 57.5% in the first quarter of fiscal year 1998.
The decrease in gross profit percentage is attributed primarily to the higher
sales mix of Undersea Systems Division products, which carry a lower gross
profit than the products of the Container Inspection Systems Division. 

Selling, General and Administrative Expenses.  Selling, general and
administrative expenses decreased by 27.0% to $905 for the first quarter of
fiscal year 1999 as compared to $1,240 in the first quarter of fiscal year 1998.
As a percentage of sales, selling, general and administrative expenses decreased
to 23.6% in the first quarter of fiscal year 1999 as compared to 39.7% for the
first quarter of fiscal year 1998.  This decrease in percentage of sales is
primarily a result of an increased level of sales in the first quarter of fiscal
year 1999,  reduced selling expenses, and lower commission expenses in the
Container Inspection Systems Division which is a direct result of reduced sales
in that division as compared to the first quarter of fiscal year 1998.

Research and Development Expenses.  Research and development expenses increased
5.6% to $285 for the first quarter of fiscal year 1999 as compared to $270 in
the first quarter of fiscal year 1998.  As a percentage of sales, research and
development expenses decreased to 7.4% of sales in the first quarter of fiscal
year 1999 from 8.7% in the first quarter of fiscal year 1998.  The increase in
the overall level of expenditures is due to investments in new product
development and is consistent with the Company's current operational plans.

Interest Income.  Interest income, net increased to $36 in the first quarter of
fiscal year 1999 as compared to $23 in the first quarter of fiscal year 1998.
The increase in net interest income was a result of the Company having paid off
all the outstanding debt in fiscal 1998, offset by slightly lower interest rates
on invested capital.

Provision for Income Taxes.  The provision for income taxes increased to $121 in
the first quarter of fiscal year 1999 as compared to $118 in the first quarter
of fiscal year 1998.  The effective tax rate used in the first quarter of fiscal
year 1999 was 36.0% as compared to the rate of 38.3% used in the first quarter
of fiscal year 1998.  The rate used in the first quarter of fiscal year 1999 is
lower than the statutory rate due primarily to the benefit from the Company's
Foreign Sales Corporation.

Liquidity and Capital Resources.  The Company's cash and cash equivalents
increased $63 from September 30, 1998 to December 31, 1998.  Cash of $69 was
provided by operating activities.  Inventories used $251 to support future
sales.  Accounts receivable increased by $175 as a result of increased shipments
in the latter part of the quarter.  Prepaid expenses decreased $152.  The
Company believes it is well positioned to finance future working capital
requirements and capital expenditures during the next twelve months through cash
on hand, current earnings and available credit facilities.

Year 2000 Issues.  During 1998 and 1999, the company has been actively engaged
in addressing Year 2000 ("Y2K") issues, which result from the use of two-digit,
rather than four-digit, year dates in software, a practice which could cause
date-sensitive systems to malfunction or fail because they may not recognize or
process date information correctly.

STATE OF READINESS:  To manage its Y2K program, the Company has divided its
efforts into four program areas:

               *    Information Technology  (computer hardware, and software)
               *    Physical Plant  (manufacturing equipment and facilities)
               *    Products  (including product development)
               *    Extended Enterprise  (suppliers and customers)
<PAGE>
 
                                                                              10

For each of these program areas, the Company is using a four-step approach:

               *    Ownership  (creating awareness, assigning tasks)
               *    Inventory  (listing items to be assessed for Y2K readiness)
               *    Assessment  (prioritizing the inventoried items, assessing
                    their Y2K readiness, planning corrective actions, developing
                    initial contingency plans)
               *    Corrective Action Deployment (implementing corrective
                    actions, verifying implementation, finalizing and executing
                    contingency plans)

As of December 31, 1998, the Ownership and Inventory steps were essentially
complete for all program areas.  The Company expects to complete the Assessment
and Corrective Action Deployment steps by June 1999.

COSTS TO ADDRESS Y2K ISSUES:  The Company began incurring expenses in 1997 to
resolve this issue.  All expenditures will be expensed as incurred and are not
expected to have a significant impact on the Company's ongoing results of
operations.

RISKS OF Y2K ISSUES AND CONTINGENCY PLANS:  The Company is in the process of
assessing the Year 2000 issues relating to its physical plant, products and
suppliers.  The Company intends to develop a contingency planning process to
mitigate worst-case business disruptions such as delays in product delivery,
which could potentially result from events such as supply chain disruptions.
The Company expects its contingency plans to be complete by June 1999.

ARTICLE II - GRANT
- ------------------

2.1   Subject to the terms and conditions hereof, LICENSOR hereby grants to
      LICENSEE and LICENSEE hereby accepts an exclusive, worldwide license to
      make, distribute, use, and sell the Licensed Products, to practice the
      Licensed Processes, and to utilize the Documentation for a period of five
      (5) years commencing on the effective date of this Agreement. The
      foregoing notwithstanding, LICENSEE and LICENSOR expressly acknowledge and
      agree that the granting by LICENSOR to LICENSEE of such exclusive license
      shall only limit for a period of three (3) years commencing on the
      effective date of this Agreement LICENSOR from making, or granting a
      license to a current or future LICENSOR Affiliate entity to make on behalf
      of LICENSOR or LICENSOR Affiliate entity, the Licensed Product, practice
      the Licensed Processes and utilize the Documentation, for LICENSOR's or
      LICENSOR Affiliate entity's use, lease, or sale as a component part of a
      product of LICENSOR or LICENSOR's Affiliate entity. The term of this
      Agreement may be extended by written agreement of the parties at any time
      prior to the expiration of the then current term of the Agreement. In the
      event of expiration or termination of the exclusive License granted by
      LICENSOR to LICENSEE hereinabove, LICENSEE shall have a non-exclusive
      worldwide license to make, distribute, use, and sell the Licensed
      Products, to practice the Licensed Processes, and to utilize the
      Documentation, on the same terms and conditions as this Agreement.
      Concurrently, LICENSEE hereby grants a reciprocal, royalty free,
      perpetual, non-exclusive license to LICENSOR with respect to utilization
      of LICENSEE's proprietary information embedded in and/or a part of the
      Licensed Processes and Documentation. The provisions herein with respect
      to these non-exclusive licenses shall survive the termination of this
      Agreement.

2.2   LICENSOR represents that it neither owns nor controls nor is aware of
      patent rights or other proprietary rights to technology which would
      prevent LICENSEE from enjoying the benefits of the rights granted to
      LICENSEE herein.

2.3   LICENSEE shall use all reasonable commercial efforts to bring to market
      the Licensed Products or Licensed Processes, including without limitation
      the generation of the Documentation. The initial design verification
      parameters and performance criteria have been mutually agreed between the
      parties hereto and are documented in Appendix A attached hereto and made a
      part hereof. The Documentation shall be deemed Work For Hire due to
      contemplation of the compensation to be provided to LICENSEE by LICENSOR
      in accordance with paragraph 4.1(B) hereof and shall be licensed to
      LICENSEE by LICENSOR under this Agreement and be subject to the terms and
      conditions hereof. Due to potential LICENSOR commercial impact known to
      and hereby acknowledged by LICENSEE, should LICENSEE fail to bring
      Licensed Products or Licensed Processes to market not later than 5 January
      1998 with a review of the status of final determination of the design path
      not later than 30 November 1997 and such failure is attributable to
      LICENSEE and LICENSOR is not in default hereunder, this Agreement may be
      terminated at the sole discretion of LICENSOR with forty-five (45) days'
      notice to LICENSEE notwithstanding other provisions herein to the contrary
      and the Documentation as it exists at the time of such termination shall
      be owned by LICENSOR and delivered to LICENSOR by LICENSEE at the time of
      such termination. All obligations of either LICENSEE or LICENSOR that by
      their nature would survive termination of this Agreement for any reason
      herein provided shall so survive.

2.4   LICENSEE agrees that any improvement, enhancement or derivative
      information or product it develops to, or that results from, the
      Proprietary Rights during the term of this Agreement, or any extension
      thereto, shall be disclosed to LICENSOR. LICENSOR shall have equal
      ownership of and/or proprietary rights to such improvement, enhancement or
      derivative information or product. LICENSEE's rights to use of any such
      improvement, enhancement or derivative information or product LICENSEE
      develops to, or that results from, the Proprietary Rights shall be equally
      licensed to LICENSEE hereunder as the original subject matter of this
      Agreement. In the event either party intends to protect said improvement,
      enhancement or derivative information or product it develops to, or that
      results from, the Proprietary Rights by filing patents, such party shall
      provide notice to the other. In the event that such party is LICENSEE and
      where the practice of resulting patent applications and patents would
      infringe Proprietary Rights, LICENSEE shall provide to LICENSOR an
      exclusive, perpetual, worldwide, royalty-free license under such patent
      applications and patents for such rights as may have been granted under,
      or derived from, such patent applications and patents. Where the practice
      of resulting patent applications and patents would not infringe
      Proprietary Rights, LICENSEE shall provide to LICENSOR a non-exclusive,
      perpetual, worldwide, royalty-free license under such patent applications
      and patents for such rights as may have been granted under, or derived
      from, such patent applications and patents.

ARTICLE III - EXPORT CONTROLS

3.1   It is understood that LICENSOR and LICENSEE are subject to United States
      law and regulations controlling the export of technical data, computer
      software, laboratory prototypes and other commodities, and that their
      obligations hereunder are contingent on compliance with applicable United
      States export laws and regulations. The transfer of certain technical data
      and commodities may require a license from the cognizant agency of the
      United States Government and/or written assurances by LICENSEE that
      LICENSEE shall not export data or commodities to certain foreign countries
      without prior approval of such agency. LICENSOR neither represents that a
      license shall not be required nor that, if required, it shall be issued.
      LICENSEE shall be responsible for payment of all reasonable costs,
      attendant to securing said licenses.

ARTICLE IV - FEE, COST BASIS/REMUNERATION, ROYALTIES, AND REPORTING

4.1.  For the rights, privileges and license granted hereunder, LICENSEE shall
      pay a license fee, provide preferred selling price and delivery status,
      and pay royalties to LICENSOR in the manner hereinafter provided to the
      end of the term of the Proprietary Rights, which shall be until the last
      patent to expire of all patents included within Proprietary Rights, or
      until this Agreement shall be terminated as hereinafter provided:

      (A)   LICENSEE agrees to pay LICENSOR a License Issue fee in the amount of
            Ten Dollars ($10.00);

      (B.1) LICENSOR shall pay LICENSEE an amount equal to $ 158,500.00 (One
            Hundred Fifty-eight Thousand Five Hundred Dollars) for the
            completion of the engineering required to place the Licensed Product
            in a high volume manufacturing design state including without
            limitation the generation of the Documentation. The fee hereinabove
            to be paid by LICENSOR to LICENSEE will include full compensation
            for all engineering design, manufacturing design, the generation and
            copying of the Documentation and any future updates thereto as and
            when initiated by LICENSEE and prototype materials required to
            fabricate parts for proof of design. Said fee shall be deemed earned
            by LICENSEE on 1) the successful completion of testing to the
            satisfaction of LICENSOR and LICENSEE to a mutually agreed upon set
            of performance specifications documented in Appendix B attached
            hereto and made a part hereof and 2) delivery to LICENSOR by
            LICENSEE of a complete and accurate reproducible copy of the then
            current Documentation. Once the fee is earned as stated above,
            payment of said fee shall be effected in stages as follows:

                  a) By issuance of an Invoice with Net payment terms for, and
            payment of, $ 108,500.00 which shall be due and payable on the later
            of 5 January 1998 or 30 days following the date upon which the total
            fee is deemed earned as stated above, and 

                  b) By retention by LICENSEE of $0.50/unit of the $2.20/unit
            portion of the royalty due LICENSOR on the first 100,000 units sold
            by LICENSEE to a third party in accordance with paragraph 4.1.(F)
            hereof.

                                  Page 5 of 14

            The work product of LICENSEE's services, including results, and all
            ideas, plans, developments, and inventions which LICENSEE conceives
            or reduces to practice during the course of performance under this
            subparagraph 4.1.(B) and this Agreement shall be the exclusive
            property of LICENSOR. This information, material, plans, and any
            such ideas or inventions shall be deemed LICENSOR Proprietary
            Information and shall not be disclosed to anyone outside of LICENSOR
            or used by LICENSEE outside the terms and conditions of this
            Agreement or used by others without the prior written consent of
            LICENSOR. Such work product which qualifies as a "work for hire"
            under the copyright laws of the United States shall be the exclusive
            property of LICENSOR as "work for hire". All right, title, and
            interest, including any copyright in and to any written data which
            does not qualify as a "work-for-hire" shall be deemed to have been
            automatically transferred to LICENSOR from the date of inception
            thereof. Upon LICENSOR's request, LICENSEE shall execute any
            document and render such other assistance as reasonably necessary to
            perfect full right, title, and interest worldwide in the written
            data, including formal conveyance of copyright. Written data shall
            not be published or submitted for publication by LICENSEE without
            the prior written approval of LICENSOR. Further, if any such
            article, paper, treatise, or report includes work previously
            copyrighted by LICENSEE, LICENSEE hereby grants to LICENSOR a
            nonexclusive, worldwide, irrevocable, paid-up license under such
            copyrights to reproduce, distribute, and use the works in any
            manner.

            During the period of this Agreement and thereafter at any reasonable
            time when called upon to do so by LICENSOR, LICENSEE shall execute
            patent applications, assignments to LICENSOR, and other papers and
            shall render such other assistance that LICENSOR believes necessary
            to secure for LICENSOR the full protection and ownership of all
            rights in and to the work product of the services performed by
            LICENSEE. The filing of patent applications on inventions made by
            LICENSEE shall be decided by LICENSOR and shall be for such
            countries as LICENSOR shall elect. LICENSOR shall bear all the
            expenses in connection with the preparation, filing, and prosecution
            of applications for patents and for all matters provided in this
            subparagraph requiring the time and/or assistance of LICENSEE as to
            inventions. Further, LICENSOR shall pay LICENSEE the hourly rate of
            $ 75.00 for services which LICENSEE performs in connection with
            inventions and patent applications which may be required by LICENSOR
            whether during the term of this Agreement or after expiration or
            termination of this Agreement. LICENSEE warrants that the
            engineering design, manufacturing design, the generation and copying
            of the Documentation and any future updates thereto shall not
            violate any third party's intellectual property rights nor include
            any unauthorized disclosure of any third party's intellectual
            property and agrees to, at its sole expense, at all times during the
            term of this Agreement and thereafter indemnify, defend, and hold
            LICENSOR, their trustees, officers, employees and affiliates
            harmless against any and all costs and/or liabilities of whatever
            nature that may result from any claim by any third party for
            infringement of such third party's intellectual property rights. The
            aforementioned documentation deemed "work for hire" shall be clearly
            marked as the property and proprietary information of LICENSOR.

      (B.2) LICENSOR shall pay LICENSEE an amount equal to $ 61,000.00
            (Sixty-one Thousand Dollars) for production tooling required by
            LICENSEE or LICENSEE's subcontractors to produce the Licensed
            Product. The fee hereinabove to be paid by LICENSOR to LICENSEE will
            include full compensation for all engineering design and
            manufacturing for production tooling required by LICENSEE or
            LICENSEE's subcontractors and any future updates thereto as and when
            initiated by LICENSEE to produce the Licensed Product. Issuance of
            an Invoice with Net 30 payment terms for, and the payment of, said
            fee is contingent on 1) the successful completion of testing to the
            satisfaction of LICENSOR and LICENSEE of Licensed Product
            manufactured using the production tooling to be tested to a mutually
            agreed upon set of performance specifications documented in Appendix
            B attached hereto and made a part hereof and 2) delivery to LICENSOR
            by LICENSEE of a complete and accurate listing of such production
            tooling with values per individual item, the extended total of which
            shall equal said fee, and the physical location address for each
            individual item. Title to such production tooling shall vest in
            LICENSOR upon payment of such invoice. LICENSOR shall have complete
            and unhindered access to such production tooling at all times.
            LICENSEE shall be responsible for maintenance and replacement of
            such production tooling as long as LICENSEE derives benefit from its
            use or until such time as LICENSOR shall take physical possession of
            it.

      (C)   LICENSEE shall manufacture the Licensed Product to the
            specifications agreed to for the use of LICENSOR and all other
            customers that may have a need for this product regardless of these
            other customers competitive position with LICENSOR.

      (D)   In consideration of granting said exclusive license to LICENSEE,
            LICENSEE will provide most favored customer status to LICENSOR with
            respect to any selling price and delivery of the Licensed Product to
            LICENSOR. NO ROYALTIES ARE DUE LICENSOR ON THE VALUE OF PRODUCTS
            SOLD TO LICENSOR. At all times that this license is exclusive to
            LICENSEE, LICENSOR will not compete with LICENSEE in the Licensed
            Product as an saleable end-item.

      (E)   LICENSEE is free to set the unit sales price of the Licensed Product
            to any LICENSEE customer. The foregoing notwithstanding and by way
            of indication of most favored customer status of LICENSOR, the Net
            Selling Price of such unit sales price to any third party will not
            be lower at any time than the actual gross selling price to LICENSOR
            for like or lesser quantity purchase commitment.

      (F)   For all sales of the Licensed Product to any organization or entity
            other than LICENSOR, LICENSEE shall pay to LICENSOR running
            Royalties in the amount of five and one half percent (5.5 %) of the
            Net Selling Price plus $ 2.20 per unit for each Commercial Sale of
            Licensed Products by LICENSEE for the first 100,000 units sold by
            LICENSEE to a third party and ten percent (10.0 %) of the Net
            Selling Price only thereafter for each Commercial Sale of Licensed
            Products by LICENSEE, said Royalty to be due and payable upon
            delivery of the report due pursuant to Paragraph 4.5 hereof. In the
            event a Commercial Sale of Licensed Products occurs together with
            the sale or 

                                  Page 7 of 14
<PAGE>
 
            lease of a system or other product, (a) such royalty shall be
            calculated solely on the Licensed Product, as no royalty shall be
            payable with respect to any other portion of such system or product;
            and (b) in the event the Net Selling Price of the Licensed Product
            is not separately stated, the royalty shall be calculated based upon
            the Net Selling Price from the most recent prior comparable
            Commercial Sale of a separate Licensed Product.

4.2   No multiple royalties shall be payable solely for the reason that any
      Licensed Products, its manufacture, use, or sale are or shall be covered
      by more than one patent application, patent or certificate of registration
      licensed under this Agreement.

4.3   Royalty payments shall be paid in United States dollars in Houston, Texas,
      or at such other place as LICENSOR may reasonably designate.

4.4   LICENSEE shall keep full, true and accurate books of account and records
      containing all particulars that may be necessary for the purposes of
      showing the amounts payable to or by LICENSOR hereunder. Said books of
      account shall be kept at LICENSEE's principal place of business or the
      principal place of business of the appropriate division of LICENSEE to
      which this Agreement relates. Said books and the supporting data shall be
      open at all reasonable times for three (3) years following the end of the
      calendar year to which they pertain, to the inspection of independent
      CPA's to be proposed by LICENSOR and approved by LICENSEE, said approval
      not to be unreasonably withheld, for the purpose of verifying LICENSEE's
      royalty statement or compliance in other respects with this Agreement,
      such inspection to occur no more than once each calendar year upon
      reasonable prior notice to LICENSEE. The expense of such inspection shall
      be borne by LICENSOR unless such inspection reveals a shortfall in
      payments due to LICENSOR by LICENSEE or other violation of the terms and
      conditions of this Agreement by LICENSEE in which case such expenses shall
      be borne by LICENSEE.

4.5   The Royalty provided in Paragraph 4.1(F) shall be payable to LICENSOR
      within in one (1) month after the end of each calendar quarter. LICENSEE
      shall have the option of paying any portions of the royalty herein
      provided at any time earlier than that specified. Each royalty payment to
      LICENSOR shall include an appropriate statement of the gross revenues due
      LICENSOR and shall identify the portion(s) of the Agreement under which
      said royalty payments are made. In addition, each royalty payment shall be
      accompanied by true and accurate reports giving such particulars of the
      business conducted by LICENSEE during the period to which such payment
      applies under this Agreement ending thirty (30) days prior to such payment
      date as shall be pertinent to an accounting hereunder.

4.6   The royalty payments set forth in this Agreement shall, if overdue, bear
      interest until payment at the maximum per annum rate permitted by
      applicable law. The payment of such interest shall not foreclose LICENSOR
      from exercising any other rights it may have as a consequence of the
      lateness of any payment.

ARTICLE. V - INFRINGEMENT
- -------------------------

5.1   Enforcement of Patent Rights. In the event LICENSEE alleges that a third
      ----------------------------
      party is infringing a right contained within Proprietary Rights, LICENSEE
      shall immediately notify LICENSOR of said alleged infringement. LICENSOR
      shall, in its sole discretion, determine whether an infringement is
      occurring and shall take whatever actions it deems necessary to enforce
      Proprietary rights. LICENSOR shall, within thirty (30) days after notice
      thereof, inform LICENSEE how and to what extent it is pursuing such third
      party. In the event LICENSEE deems such action to be insufficient,
      LICENSEE shall have, with LICENSOR's prior written consent signed by an
      officer of LICENSOR, such consent not to be unreasonably withheld, the
      right, in LICENSOR's name, to pursue such infringer, as LICENSEE may
      reasonably deem appropriate; provided, however, that in the event LICENSEE
      takes such action in LICENSOR's name, it shall provide LICENSOR prior
      written notice thereof, shall keep LICENSOR fully informed of the progress
      thereof and shall act in a reasonable manner at all times in connection
      with the prosecution thereof. In the event LICENSOR recovers any amounts
      from such third party as a result of any action taken by LICENSOR,
      LICENSOR shall deduct therefrom the out-of-pocket legal and related
      expenses LICENSOR incurred in obtaining such amount, retain a percentage
      of the remainder equal to the percentage that the royalty fee
      hereinprovided is of the then current Net Selling Price and remit the rest
      to LICENSEE. In the event LICENSEE recovers any amounts from such third
      party as result of any action taken by LICENSEE, such amounts shall be
      treated as a Net Selling Price hereunder, provided that LICENSEE shall
      deduct therefrom the out-of-pocket legal and related expenses it incurred
      in obtaining such amounts prior to paying Royalties thereon. LICENSOR may
      bring and prosecute suits for infringement against others under the
      Proprietary Rights. LICENSOR shall retain whatever financial recoveries
      are obtained from said litigation and shall bear all the expenses of the
      litigation.

5.2   Prosecution of Patents. LICENSOR shall, at its sole discretion and
      ----------------------
      expense, diligently prosecute any patent applications included within
      Proprietary Rights.

      -------------------
      against LICENSEE alleging that LICENSEE's exercise of the Proprietary
      Rights infringe any rights of such third party, LICENSOR shall, with the
      reasonable cooperation of LICENSEE, defend LICENSEE against such claim at
      the expense of LICENSOR and LICENSOR shall pay any settlement amount or
      the damages that a court of competent jurisdiction awards, plus any other
      costs and expenses incurred by LICENSEE in connection therewith provided
      LICENSEE shall a) promptly notify LICENSOR in writing of any such claim,
      b) allow LICENSOR to control such defense and any related settlement
      negotiation, and c) cooperate with LICENSOR in the defense of any such
      claim or any related settlement negotiations.

      and Documentation and except as otherwise provided in Paragraph 2.1
      hereof.

             affiliates harmless against any and all costs and/or liabilities of
             whatever nature that may result from any claim by any third party
             for infringement of such third party's intellectual property
             rights. The aforementioned documentation deemed "work for hire"
             shall be clearly marked as the property and proprietary information
             of LICENSOR.

      (B.2)  LICENSEE shall provide engineering services to determine what
             production tooling will be necesary and provide such production
             tooling required by LICENSEE or LICENSEE's subcontractors to

             required by LICENSEE or LICENSEE's subcontractors and any future
             updates thereto as and when initiated by LICENSEE to produce the
             Licensed Product. Such services shall be deemed initially completed
             by LICENSEE on 1) the successful completion of testing to the
             satisfaction of LICENSOR and LICENSEE of Licensed Product
             manufactured using the production tooling to be tested to a
             mutually agreed upon set of performance specifications documented
             in Appendix B attached hereto and made a part hereof and 2)
             delivery to LICENSOR by LICENSEE of a complete and accurate listing
             of such production tooling with values per individual item. Title
             to such production tooling provided by LICENSEE to itself and its
             subcontractors shall be held by LICENSEE. LICENSEE shall be
             responsible for maintenance and replacement of such production
             tooling as required.

      (C)    LICENSEE shall manufacture the Licensed Product to the
             specifications agreed to for the use of LICENSOR and all other

Amendment Number 1


      (D)    In consideration of granting said exclusive license to LICENSEE,
             LICENSEE will provide most favored customer status to LICENSOR with
             respect to any selling price and delivery of the Licensed Product
             to LICENSOR. NO ROYALTIES ARE DUE LICENSOR ON THE VALUE OF PRODUCTS
             SOLD TO LICENSOR. At all times that this license is exclusive to
             LICENSEE, LICENSOR will not compete with LICENSEE in the Licensed
             Product as an saleable end-item.

      (E)    LICENSEE is free to set the unit sales price of the Licensed
             Product to any LICENSEE customer. The foregoing notwithstanding and
             by way of indication of most favored customer status of LICENSOR,
             the Net Selling Price of such unit sales price to any third party
             will not be lower at any time than the actual gross selling price
             to LICENSOR for like or lesser quantity purchase commitment.

      (F)    For all sales of the Licensed Product to any organization or entity
             other than LICENSOR up to the combined, cummulative amount of the
             first 250,000 units, LICENSEE shall not be required to pay any
             running Royalties to LICENSOR. For all sales of the Licensed
             Product to any organization or entity other than LICENSOR following
             such first 250,000 units, LICENSEE shall pay to LICENSOR running
             Royalties in the amount of $0.75 per unit for each Commercial Sale
             of Licensed Products by LICENSEE - said Royalty to be due and
             payable upon delivery of the report due pursuant to Paragraph 4.5
             hereof. In the event a Commercial Sale of Licensed Products occurs
             together with the sale or lease of a system or other product, such
             royalty shall be solely on the Licensed Product, as no royalty
             shall be payable with respect to any other portion of such system
             or product.

4.2  No multiple royalties shall be payable solely for the reason that any
     Licensed Products, its manufacture, use, or sale are or shall be covered by
     more than one patent application, patent or certificate of registration
     licensed under this Agreement.

4.3  Royalty payments shall be paid in United States dollars in Houston, Texas,
     or at such other place as LICENSOR may reasonably designate.

4.4  LICENSEE shall keep full, true and accurate books of account and records
     containing all particulars that may be necessary for the purposes of
     showing the amounts payable to or by LICENSOR hereunder. Said books of
     account shall be kept at LICENSEE's principal place of business or the
     principal place of business of the appropriate division of LICENSEE to
     which this Agreement relates. Said books and the supporting data shall be
     open at all reasonable times for three (3) years following the end of the
     calendar year to which they pertain, to the inspection of independent CPA's
     to be proposed by LICENSOR and approved by LICENSEE, said approval not to
     be unreasonably withheld, for the purpose of verifying LICENSEE's royalty
     statement or compliance in other respects with this Agreement, such
     inspection to occur no more than once each calendar year upon reasonable
     prior notice to LICENSEE. The expense of such inspection shall be borne by
     LICENSOR unless such inspection reveals a shortfall in payments due to
     LICENSOR by LICENSEE or other violation of the terms and conditions of this
     Agreement by LICENSEE in which case such expenses shall be borne by
     LICENSEE.

4.5  The Royalty provided in Paragraph 4.1(F) shall be payable to LICENSOR
     within in one (1) month after the end of each calendar quarter. LICENSEE
     shall have the option of paying any portions of the

Amendment Number 1


     royalty herein provided at any time earlier than that specified. Each
     royalty payment to LICENSOR shall include an appropriate statement of the
     gross revenues due LICENSOR and shall identify the portion of the Agreement
     under which said royalty payments are made. In addition, each royalty
     payment shall be accompanied by true and accurate reports giving such
     particulars of the business conducted by LICENSEE during the period to
     which such payment applies under this Agreement ending thirty (30) days
     prior to such payment date as shall be pertinent to an accounting
     hereunder.

4.6  The royalty payments set forth in this Agreement shall, if overdue, bear
     interest until payment at the maximum per annum rate permitted by
     applicable law. The payment of such interest shall not foreclose LICENSOR
     from exercising any other rights it may have as a consequence of the
     lateness of any payment.

2.   Replace Appendix A dated October 16, 1997 in its entirety with Appendix A
     dated June 18, 1998.


3.   Replace Appendix B Revision E dated October 17, 1997 in its entirety with
     Appendix B Revision G dated May 26, 1998.

4.  All other terms and conditions of the Agreement remain unchanged.


IN WITNESS THEREOF, the parties have hereunto set their hands and duly executed
